1 INTRODUCTION

1.1 Background

The federal Clean Water Act (CWA) provides that discharges from point sources to waters of the United States are prohibited, unless in compliance with a national pollutant discharge elimination system (NPDES) permit. As an EPA approved state program, the Oregon Department of Environmental Quality (DEQ) is responsible for implementing these regulations and issuing NPDES permits. In 1991, DEQ adopted a series of NPDES General Stormwater Discharge Permits that applied to different industrial sectors. In 1997, DEQ consolidated these sector specific general permits and issued a statewide Industrial Stormwater General Permit (1200-Z permit) that covers a broad range of industries throughout the state. These permits expire every five years. DEQ renewed the 1200-Z permit in 2002, 2007, 2012, and 2017 with a reissuance in October 2018 as part of a negotiated settlement agreement between Columbia Riverkeeper, Northwest Environmental Defense Center, and Oregon Industrial Stormwater Group. The current 1200-Z general permit became effective on August 1, 2017, and expires on July 31, 2022. Portland’s Metro Property and Environmental Services (Metro) received its current version of the 1200-Z permit on October 24, 2018; a copy of the assignment letter and reissued permit is provided in Appendix A.

1.2 Purpose

The development and implementation of a stormwater pollution control plan (SWPCP) is one of the requirements of the 1200-Z permit (“permit”). The SWPCP is a guidance document intended for use by facility operator Allied Waste Transfer Services of Oregon, LLC (dba Republic Services, Inc.) personnel and Metro staff to minimize releases of pollutants to surface water from operations at the facility. The 1200-Z permit contains benchmarks for specific chemicals of concern, which are guideline concentrations designed to assist the site in evaluating the effect of management practices on stormwater discharge. In addition, the October 2018 revised permit requires sampling for impairment pollutants for facilities that discharge to impaired waters, or sampling for sector-specific pollutants that apply to primary industrial activity. These additional sampling requirements are listed in the permit assignment letter. A summary of key stormwater permit requirements is shown in Table 1-1.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 1-1

1.3 Pollution Prevention Team

Pollution Prevention Team Leader, operations manager and spill coordinator is Armando Arellano. Operational employees shall receive training in site best management practices (BMPs) and goals of the SWPCP, spill prevention and control, good housekeeping, and significant materials management practices.

1.4 Definitions

A copy of the general permit and the DEQ's permit assignment letter can be found in Appendix A. Applicable BMPs from DEQ’s 2013 Industrial Stormwater Best Management Practices Manual are included for reference in Appendix B (DEQ, 2013). The following terms are used in this document and are established in the “General Permit, National Pollutant Discharge Elimination System, Stormwater Discharge Permit” and the August 2017 Technical Assistance for Industrial Operators developed by the DEQ. .

Source Control BMPs. Physical, structural or mechanical devices or facilities that are intended to prevent pollutants from entering storm water. A few examples of source control BMPs are erosion control practices, maintenance of stormwater facilities, constructing roofs over storage and working areas, and directing wash water and similar discharges to the sanitary sewer.

Treatment BMPs. BMPs that are intended to remove pollutants from stormwater. A few examples of treatment BMPs are detention ponds, oil-water separators, biofiltration, and bioswales.

Operational BMPs. Schedule of activities, acceptable practices, maintenance procedures, employee training, housekeeping, and other managerial practices to prevent or reduce the pollution of the waters of the state.

Discharge Point. This is a defined point where stormwater runoff is collected and from which it may leave the site. Examples are pipes, ditches, channels, tunnels, and conduits.

1.5 Revisions Schedule

This SWPCP should be revised and updated to address changes in site conditions, new or revised government regulations, and additional on-site stormwater pollution controls. Revisions to the SWPCP will be documented on the Revision Table in Appendix G. Any revisions to this document or newly developed Corrective Action Responses should be added to Appendix G: Revisions, Annual Reviews and Corrective Action Responses.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 1-2

1.6 Annual SWPCP Review

The pollution prevention team will review the SWPCP on an annual basis. As part of the review, the team will inspect the site to ensure that procedures and best management practices are being followed, make sure that reports and corrective action responses are completed and filed, and update this SWPCP as needed. The annual review will be recorded in the Annual Review table in Appendix G.

2 SITE DESCRIPTION

2.1 General Information and History

Metro South Station (MSS) is a regional solid waste and recycling center that has operated since April of 1983. The site and facilities are owned by Metro. Metro staffs and operates the Household Hazardous Waste Facility (HHWF) and the Scale Houses. Metro contracts with Republic Services, Inc. (Republic) to process and recycle solid waste at the transfer station. The contractor has responsibility for meeting discharge permit requirements and is required to maintain the facility and its equipment.

The facility is classified in the permit assignment letter as SIC 4953, which is assigned to Sector K, Refuse Systems (hazardous waste treatment and disposal), in the new 1200-Z permit.

2.2 Site Description

Metro South Station is located within the city limits of Oregon City at 2001 Washington Street, in Clackamas County (Figure 1). The facility is bordered by Washington Street along the east and a rail line along the west. Just beyond the railroad grade is a newly constructed 6-acre floodplain mitigation site that is used by the Oregon Department of Transportation for treatment of stormwater from adjoining streets and from Interstate 205, which is just west of the site. Land use in the immediate vicinity is predominantly light industrial and commercial. Site access is restricted by fencing. Buildings and gates are locked when the site is unoccupied. The building and surrounding yard are equipped with an alarm system that is activated when the site is unoccupied.

2.3 Industrial Activities

Metro South Station contains three buildings totaling more than 80,000 square feet of area to receive and process waste, a 5,000 square foot maintenance building and three scale houses. More than 90 percent of all the structures on site have painted metal roofs and most have painted metal siding or a mix of metal and concrete siding. Vehicle traffic and processing activities are on concrete or asphalt surfaces.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 2-1

The site receives and process solid waste and recyclable material from commercial and residential sources. The site has two processing buildings where solid waste and recyclable material is unloaded for processing indoors, undercover. The main building has two processing areas, Bay 1 and Bay 2, that are separated by a disposal pit (referred to as the “pit”). Bay 1 is primarily used for commercial customers that have no recoverable material; they tip their loads directly into the pit for transfer to the landfill. Bay 2 is used to process drier waste loads to sort out the recyclable items; waste left over is placed in the pit. The other building, Bay 3/4, is a single large open area that is utilized as two bays. Bay 3 is primarily used to sort dry waste for recoverable material. Bay 4 is used to receive and process residential yard debris. Bay 3 has a conveyor set-up to improve sorting efficiency; non-recyclable material is loaded into a container and taken to Bay 1 for disposal in the pit. Loads containing only wood and yard waste are deposited inside Bay 4.

Wet waste and other materials that have no recoverable value are reloaded into sealed trailers for transfer to a landfill. Dry waste is sorted to extract materials that have recoverable value. Recovered materials are loaded typically into top load containers and shipped to markets. Trailers of waste and containers of recycled materials are stored outside on pavement until shipment. Recyclable goods in uncovered commodity boxes awaiting transport are temporarily stored beneath tents until shipped. Shipments are sent off site Monday through Saturday.

The site also receives and processes federally exempt hazardous waste from households and conditionally exempt generators at the HHWF located at the main entrance to the site. Waste types include acids, bases, cleaners, solvents, pesticides, herbicides, poisons, petroleum products, and paints. Hazardous materials are shipped from the site at least once a week. Some reusable materials (such as household cleaners) are stored on site to be given away.

The main building also has a room on the west side referred to as the tunnel. The room is used to store materials for use in the HHWF. There is personal protective equipment, facility supplies, used oils and antifreeze, and reusable products stored in this area. Floor drains in this room flow to a pump station. Pumps are normally off to prevent a release to the sanitary sewer.

Materials received at the HHWF are processed and shipped to recovery, disposal or treatment facilities consistent with hazardous waste regulations. Loading and unloading at this facility is done under canopy. The concrete receiving and shipping floors are sloped to drain to blind sumps in case of accidental spill. All materials are processed inside the building or under the cover of the receiving canopy by trained personnel. The inside of the building was constructed with floor pits to contain spills and fire water. The area under the receiving canopy was constructed to divert accidental spills to a containment sump for isolation and cleanup.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 2-2

There are three scale houses on the site where Metro staff weigh materials delivered to the facility, collect user fees, and record transaction information. A truck scale is located beside each scale house.

At the northeast end of the site is a 5,000 square foot building dedicated to maintenance.

The Truck Wash is a three-sided building used by commercial solid waste customers for rinsing residual waste and leachate from their collection vehicle. The concrete and paving at this wash area slope towards a collection trench that is connected to the sanitary sewer system.

There are no stormwater drains in the processing areas of these buildings. If stormwater contamination were to occur from process areas, it would likely occur from track out on tires of vehicles using the facilities. Roof drains from buildings on site direct water to pavement where it can flow to a catch basin or is piped directly to a nearby stormwater catch basin. One exception is the roof drain at the southeast corner of the main building: it is piped to the ditch along Washington Street.

2.4 Identification of Impacts from Previous Operations

Metro South Station has been in operation since 1983. Interviews with facility employees indicate that no significant chemical spills have occurred during the past five or more years of operations. No evidence of significant spills or leaks was identified during the October 2017 facility inspection.

Based on site history, the presence of extensive paving, and the spill history, it is unlikely that previous operations are a source of contamination in stormwater to the points of discharge.

2.5 Hours of Operation

The facility is open to the general public year round (except New Years, Thanksgiving, and Christmas), seven days a week. The facility's hours are 7 am to 7 pm (March through September, but closes at 6 pm during Fall and Winter months). Commercial accounts can access the site earlier than 7 am through an automated gate. The HHWF is open from 9 am to 4 pm, except closed on Sunday.

2.6 Stormwater Drainage Areas and Monitoring Locations

Figure 2 shows drainage areas, drainage patterns, discharge points, potential pollution- generating activities (e.g., vehicle parking and drop box storage areas, etc.), existing

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 2-3

stormwater control measures and surface water bodies. These features are discussed in the following sections.

It should be noted that all four of the drainage areas flow to the detention/wet pond via conveyances and, as such, comprise the overall facility watershed. Sampling of this composite watershed will occur at the detention/wet pond discharge that is designated as Discharge Point 006. The designations for the inlets to the pond that are no longer sampled will be retained for historical purposes and are shown on the site figure with updated sequential designations per the new permit requirements for electronic reporting (i.e., 001, 002, etc.).

Northeast Drainage Area. This area is predominantly paved or occupied by buildings. Rainwater sheet flows on the pavement and drains into a series of east-west aligned catch basins. Water then flows through a sand/oil separator before discharging at Discharge Point 001 to an open, but vegetated ditch. This "North Ditch" functions as a bioswale and follows the property line with the railroad, also collecting water from upstream to the east and from the railroad grade. The ditch continues west where it is plumbed to the wet pond via a 30-inch storm pipe with a flap valve.

Mid-North Drainage Area. This drainage is primarily paved, and contains the vehicle scales. Part of this basin also drains from the north half of the main building (Bay 2). Stormwater is collected by catch basins or by drains from beneath the scales. These are plumbed via a 24-inch diameter storm drain to Discharge Point 004 that discharges to the east end of the wet pond.

West Drainage Area. This drainage captures water from the entrance parking areas and traffic lanes, the HHHW facility, and the southwest part of the main building. Stormwater is piped by a 15-inch diameter storm drain to Discharge Point 005 that discharges to the east end of the wet pond, just south of Discharge Point 004.

Southeast Drainage Area. The southeast drainage comprises several subdrainages that are conveyed (via pumping) to the South Ditch along Washington Street, which flows through Discharge Point 007 to the wet pond. Stormwater in the southeast area is collected from portions of the roofs on Bay 3/4 and the Main Building, the pavement and permeable brick areas east of Bay 1, the landscape areas surrounding the access road, and the access road. The majority of drainage in the southeastern area is captured in a pump station that acts as a sand/oil separator. The pump station transfers the stormwater to a trapped catch basin upstream of the discharge point into the Washington Street ditch. The area over and east of the main building enters the same trapped catch basin. The truck wash area has a 10 by 60 foot area of pavement in front (west) of the truck wash that drains to sanitary sewer, the roof and other pavement drain to storm along with a small area of landscaping. There is also a sand/oil separator upstream of the discharge point of this area into the Washington Street ditch.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 2-4

The South Ditch is vegetated and designed to function as a bioswale. A compost filter is maintained at the west end of the South Ditch near the MSS main entrance. In addition, a portion of the Bay 1 roof drains through a downspout that discharges to the Washington Street ditch. Discharge Point 007 is located at the west end of the ditch.

Detention/Wet Pond. The detention pond lies within the western apex of the property. The wetted surface area of the pond is approximately 30,000 square feet, but varies depending on the water level. The overall western property area that contains the vegetated upland and pond surface comprises approximately 2 acres. The pond area is vegetated with deciduous and evergreen trees as well as a variety of vegetation adapted to function in both dry and wet environments. There are five inlets to the detention pond. Two of these are from the stormwater collection pipes for the Mid-North and West Drainage areas of the MSS property (Discharge Point 004 and 005, respectively). One inlet is from the stormwater collected at curb inlets along Washington Street. The other two inlets are from the North Ditch, which derives water from the Northeast Drainage Area and off-site upstream areas, and the South Ditch via Discharge Point 007.

The detention pond is graded to drain from east to west through a weir at the mid-point of the pond. Water eventually discharges at the west end through Discharge Point 006 to the municipal stormwater system. Discharge Point 006 will be the designated monitoring location for the facility, being the most downstream point of the water quality treatment train for the site.

2.7 Impervious and Pervious Areas

Building roofs, impermeable pavement surfaces and permeable landscape surfaces are identified on Figure 2. There are four drainage areas plus the detention/wet pond area; surface area estimates for each drainage area are as follows:

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 2-5

2.8 Receiving or Impaired Waters

Stormwater is discharged from this site to the local municipal storm system via a 48-inch culvert pipe that drains the on-site stormwater detention/wet pond. The downstream municipal system includes open ditch and drainage pipe conveyances to a wetland that discharge into Clackamas Cove, and ultimately to the Clackamas River. In its permit assignment letter (DEQ, 2018), the DEQ identified the impairment pollutants biological oxygen demand (BOD), dissolved lead, and mercury for the Clackamas River.

2.9 Stormwater Run-On

Run-on is received from up gradient property and adjacent local streets. Stormwater from Highway 213 and Washington Street is collected and piped directly to the MSS detention/wet pond.

Run-on to the North Ditch, upstream of Discharge Point 001, is from the railroad bed, contiguous MSS and State of Oregon landscaped areas, and upstream sources (ODOT, 2010). West (i.e., downstream) of Discharge Point 001, the North Ditch water flows beneath a trestle to a localized depression north of the railroad tracks that provides additional storage and currently functions as a large floodplain mitigation area. Runoff collects in this depression until it equalizes at which point flow in the North Ditch then continues westerly to the detention pond.

2.10 Significant Materials

There are no clean-up activities for past contamination of the site. The following tables list the significant materials that are treated, stored or used on site. The tables also identify the quantity of each material, where it may be stored, its usage and how stormwater is protected.

Quantities vary in the operation of the HHWF. Materials are shipped from the HHWF at least once per week. This keeps the volume of waste on site to a manageable amount. An inventory sheet is completed each day to record the amount of materials in and around the facility.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 2-8

2.11 Inventory of Materials and Potential Pollutants

The primary activities on this site are accepting and processing municipal solid waste (MSW) and HHW. Maintenance of the facilities and equipment are secondary activities to the operation. A truck rinsing station is also provided for commercial MSW haulers and a diesel fueling area is provided for equipment used on site.

Accepting and processing of MSW and HHW occur within buildings or under canopied receiving/shipping areas. These processing areas were designed with floors that either slope inward or are flat to prevent any liquids from flowing out into open areas. There is risk of debris and sediment being tracked and blown out from MSW processing. There is risk of hazardous waste spillage from customer vehicles and from moving materials to storage.

Maintenance is usually done within the processing areas or the dedicated maintenance building. Equipment fueling is done outside on the east side of Bay 2. There is risk of fuel, oil and grease contamination from fueling and equipment break down.

The truck wash was designed with a floor that slopes to the sanitary sewer drains. Trucks back in and rinse out their trash containers. Residual trash is picked up and placed in bins within the wash area. Rinse water flows to the rear of the wash area and is captured in a trench drain for disposal to the sanitary sewer system. There is risk from blowing debris and vehicles tracking out wash water. In response to a DEQ compliance inspection in March 2018, Metro is initiating a project to install a catch basin outside of the truck wash to intercept potentially contaminated stormwater from truck rinsing and divert it to the sanitary sewer system. This project requires approval from the sanitary sewerage district and a building permit. The estimated cost is $25,000 and installation is anticipated to be completed by December 1, 2018.

There is some risk of stormwater pollution from vehicles and mobile equipment that could leak fluids or track-out materials from the processing areas and truck wash. Routine maintenance of onsite equipment reduces the risk of fluid leaks. Good housekeeping in the process areas and truck wash reduce track out. Sweeping activities occur daily to reduce tracking and buildup of sediments and debris.

Pollutants that have the greatest potential of being present in the stormwater discharge from MSS are listed in Table 2-4.

3 SITE CONTROLS

Schedule A of permit 1200-Z requires a description of the stormwater contamination controls appropriate for the site. This section follows that part of the permit, discussing stormwater management controls and practices, and employee education, with the exception of spill prevention and response, which is discussed in Section 4.

3.1 Best Management Practices (BMPs)

Control measures and BMPs are practices or procedures that include methods to prevent toxic and hazardous substances from reaching receiving waters. The permit refers to BMPs as "Narrative Technology Based Effluent Limits." The BMPs described in this section are designed to address the facility’s practices and procedures, and ultimately affect the ability of the facility to meet benchmarks. The following subsections, as well as Section 4, discuss specific BMPs identified for the site to address Schedule A.1 and A.3 of the permit.

There are three general categories of BMPs. Source control BMPs are structural practices (i.e., physical, structural or mechanical devices or facilities) intended to prevent pollutant constituents from entering stormwater. Treatment BMPs govern pollutant removal from stormwater before discharge. Operational BMPs consist of a schedule of activities and a list of acceptable practices to prevent the potential for pollutants from entering stormwater. Applicable sections of the DEQ’s 2013 guidance (DEQ, 2013) on BMPs for industrial activities are listed below and included in Appendix B for reference.

3.1.1 Minimize Exposure

3.1.1.1 Containment Stormwater is protected from releases by providing secondary containment to liquids that are stored outside. A 2,000 gallon double walled aboveground storage tank (AST) containing diesel is located outside on the east side of Bay 2. Fifty gallons of de-icing fluid is kept in a self-contained secondary containment work station capable of holding two 55 gallon drums at the east side of the transfer trailer scale. Latex paint is contained in plastic lined storage cages and stored in the parking lot at the northeast end of the site. Thirty-five gallons of hydraulic fluid is stored on a secondary containment tray in a shed at the east side of Bay 3. Secondary containment is routinely checked to ensure that the primary vessel is not leaking. Latex paint is only stored temporarily; it ships off site twice a week. Spill kits are located near outside liquid storage areas to ensure quick response to accidental spills.

3.1.1.2 Stormwater Diversion Pavement slopes away from buildings and processing areas to keep stormwater from becoming contaminated.

1. A trench drain is installed at the loading dock for the HHWF to collect rainwater that is blown in under the loading canopy; this water is diverted to a storage sump for evaluation before disposal. Refer to the MSS HHW Emergency Containment Tank SOP in Appendix D.

2. A sump for the unloading/receiving area for the HHWF collects rainwater that is blown in under the canopy. Refer to Appendix D for the MSS HHW SOP noted above.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 3-2

3. A valve installed in the discharge pipe from the curb inlet on the south side of the HHWF receiving canopy can be closed if a spill threatens to enter the storm system.

4. A valve in the storm pipe leading to Discharge Point 005 (West Drainage Area) can be closed if a spill threatens to enter the pond.

5. A valve in the discharge pipe from the bottom of the truck ramp on the north side of Bay 3/4 can be closed if there is a spill while loading from this area.

6. A trench drain installed at the bottom of the truck ramp to the loading area on the south side of Bay 3/4 captures stormwater flowing down the truck ramp. This drains to a nearby stormwater catch basin. Rainwater that falls on the concrete slab west of this trench drain, in the loading area, is diverted to sanitary sewer.

7. Rainwater that falls on the pavement in the truck wash or within 10 feet of the front of the truck wash (east side) is diverted to sanitary sewer.

8. A trench drain on the east end of the concrete slab, where trailers that use the compactors are loaded, captures stormwater flowing down the access drive; this drains to a stormwater pump station. Rainwater that falls on the concrete slab west of this trench drain is diverted to sanitary sewer.

3.1.1.3 Covering Activities Most activities posing a risk to stormwater quality are performed under building cover. Liquids and waste materials stored outside near HHWF are placed in containers with lids or under canopies. Some source separated wastes, including construction materials (wood, sheetrock) are staged outside and removed from MSS on a daily basis.

3.1.2 Oil and Grease

There are four stormwater collection points that function to separate oil and grease. One is a pump station at the east end of the concrete slab where trailers are loaded by the compactors at the east end of the pit in the main building. There is an oil-water separator (OWS) in the northeast parking area, just north of the lunchroom for Bay 3/4. Another OWS is behind and southeast of the truck wash. Finally there is a sump and pump station west of the tunnel near the HHWF. A vacuum truck regularly pumps these OWS and stations and disposes of the wastes off-site.

The compost filter in the south ditch along Washington Street is filled with leaf compost to adsorb petroleum products and metals. The vegetated ditches (both North and South

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 3-3

Ditches) also remove petroleum products from stormwater. The final control device is the detention/wet pond that can further reduce petroleum contamination in stormwater.

3.1.3 Waste Chemicals and Material Disposal

MSS is a solid waste and recycling center as well as a drop off location for household hazardous waste. There are varying amounts and types of materials handled and stored on the site. Further detail is provided in sections 2.10 and 2.11.

3.1.4 Erosion and Sediment Control

The MSS site has a well established landscape. There are no exposed areas susceptible to erosion. However, dirt and debris are deposited on paved surfaces from vehicles using the facilities.

Sediment in stormwater discharge is controlled with Lynch-Type sedimentation basins/manholes, grassy swales/ditches and the detention/wet pond. Catch basins on site have been fitted with filter inserts (witches hats) to enhance sediment and pollution capture. These control measures are routinely monitored and maintained.

In the Northeast Drainage Area, additional controls address TSS runoff from the pavement. The area used for long-haul truck parking is swept on designated weekend days when the site is less congested. Trailers are pulled forward and the area behind them is hard-brushed (as necessary) and then gone over with the sweeper truck. This removes sediment tracked onto the site and subsequently mobilized by stormwater.

Outlet protection has been established at each stormwater discharge point. A riprap or concrete apron has been used to prevent scour and minimize downstream erosion.

3.1.5 Debris Control

Booms, oil socks, and catch basin filters are used in areas susceptible to debris from wind or track-out. These control/safety devices are inspected routinely and replaced as needed. Sweeping with a vac-truck is also conducted on all high-use paved areas of the facility at least once per day.

3.1.6 Dust Generation and Vehicle Tracking of Industrial Materials

Sweeping is conducted on all paved areas of the facility at least once per month with daily sweeping of the primary areas of vehicle traffic and parking by an outside contractor.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 3-4

Sweeping reduces the amount of debris on the paved areas, thereby reducing the amount of material tracked out when leaving the site.

Metro will take the following action to reduce track out from the processing buildings:

• Sweep floors 30 to 40 feet inside of the processing buildings each day.

• Reduce the use of water on the process floors to prevent dust and instead, will increase sweeping.

A truck wash is available for commercial haul trucks using the site. The trucks pull into a contained, covered wash area and spray down prior to leaving the site. The truck wash discharges to the sanitary sewer. The discharge is permitted by Industrial Wastewater Discharge Permit # 02T-004-0, provided by Tri-City Service District (Oregon City, Oregon). As mentioned in Section 2.11, Metro is planning to install a catch basin outside of the truck wash to intercept potentially contaminated stormwater from truck rinsing and divert it to the sanitary sewer system.

3.1.7 Housekeeping

Good housekeeping is necessary to maintain a clean and orderly environment at the site. Housekeeping is often the most effective first step towards controlling stormwater pollutants. Solid waste, hazardous waste and recyclable materials are properly handled and promptly removed from the site. Examples of good housekeeping practices employed at the site include:

• Minimizing contamination of stormwater runoff from areas used for vehicle and equipment maintenance, storage, and cleaning. Maintenance is usually done within the processing areas or the dedicated maintenance building. Depending on the situation and type of equipment, measures to reduce exposure of equipment or vehicles to stormwater possibly include: use of drip pans under vehicles/equipment that are leaking, under-cover storage of vehicles and equipment, use of absorbents, or cleaning pavement surfaces to remove oil and grease.

• Proper storage of petroleum products, hazardous substances, and waste materials.

• Oil and fuel are recycled to the maximum extent practicable.

• Minimize contamination of stormwater runoff from fueling areas by using spill/overflow protection and cleanup equipment, and by minimizing stormwater run-on to the fueling area.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 3-5

• Prompt attention to leaks and spills of contaminants (liquid or solid) from site operations that may occur on any exposed soil, vegetation, or paved areas.

• Prevent the accumulation of liquid or solid chemicals on the ground near storage areas.

• Sweep paved areas of the facility at least once per month with daily sweeping of the primary areas of vehicle traffic and parking.

• Inspect catch basins at least monthly, and as needed, remove sediment, oil, debris, sludge, etc. Catch basins are scheduled for cleaning in the fall before the wet season, and then every 3 months. Depending on the amount of sediment collecting in the catch basin insert, it can be taken out and cleaned and then reinstalled. Catch basin inspection and cleaning is documented with a checklist; an example can be found in Appendix D.

• Spill response kits are located to facilitate expeditious cleanup (spill kit locations are shown on figures).

• Cover and contain materials, equipment, and waste that could leach pollutants to stormwater.

Personnel inspect areas of industrial activities throughout the work day, with additional documented inspections for housekeeping occurring at least monthly (see Section 5). Housekeeping needs will be taken care of routinely throughout the work day and not be allowed to get out of hand.

3.1.8 Treatment Structure-Detention/Wet Pond

Stormwater from the site flows into a detention/wet pond that Metro constructed at the west end of the facility. This technology has demonstrated to be effective at treating stormwater based on historical water quality data for the site. An engineering analysis that was performed by Wallis Engineering for Republic and Metro evaluated both the capacity of the pond to adequately treat the water quality to below benchmarks and to handle the volume of water derived from the site. This analysis was done as part of the Tier II treatment measures for the site in 2014. The engineering evaluations concluded that the pond has the ability to reduce the pollutants to below benchmarks and has sufficient capacity to accommodate the 10-year design storm within its current boundaries and with sufficient freeboard.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 3-6

3.2 Preventive Maintenance

In addition to measures that minimize contact of rainwater with pollutant sources, preventative maintenance reduces potential for impacts to stormwater. Routine preventive maintenance by Republic personnel complements good housekeeping and is crucial in reducing the amount of pollutants discharged with stormwater runoff. Each month, Republic personnel inspect areas where potential spills of significant materials could impact stormwater runoff, control structures, or other treatment facilities.

Preventive maintenance can include, but is not limited to:

• Place drip pans to collect leaks and spills from equipment and vehicles, and empty them on a regular basis so they do not overflow.

• Store spill prevention materials (i.e., drip buckets/pans, secondary containment bins, etc.) and spill kits in a location where they are readily accessible during emergencies.

• Dispose of used spill prevention materials in accordance with applicable regulations, and replace used materials with new or cleaned materials as they are used.

• Lock master flow and drain valves that permit direct discharge from ASTs in the closed position when in non-operating status.

• Floor and sink drains may not be connected to storm drains, surface water, or to the ground.

• Cover stored oily rags, equipment parts, and other oily materials by placing them into closed and labeled containers, in covered buildings, steel storage boxes, or under tarps.

• Store liquids in compatible containers. Containers should be rigid and durable, corrosion resistant, non-absorbent, water tight, rodent-proof, and equipped with a close fitting cover.

• Procedures for Metro to manage liquids collected in two subsurface holding tanks adjacent to the household hazardous waste facility have been developed and maintained by Metro as a standard operating procedure (See Appendix D).

• Sediment basins and sumps are inspected monthly during the rainy season for substantial buildup, and periodically during the rest of the year.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 3-7

• Stormwater catch basins and other conveyance are inspected at least monthly to insure that they are free of sediment buildup, debris, or obstructions. The inlets and outlets shall be periodically cleaned, as necessary.

• Ditches and the bioswale will be inspected monthly for signs of damming due to sediment build-up or debris (including excessive grass growth) and other possible problems. Repairs will be made as needed during the dry months. The compost in the biofilter upstream of discharge point 007 is replaced annually.

See Visual Monitoring - Monthly Inspection Form in Appendix D which provides a checklist for preventive maintenance activities.

3.3 Employee Education

Republic will train designated employees to identify pollutant sources and potential pollutants, and understand pollutant control measures, spill response procedures, good housekeeping practices, and environmentally acceptable material handling practices, particularly those related to vehicle fueling, handling vehicle and equipment liquids (i.e., fuels, oils, hydraulic fluids, etc.).

Employee meetings will be held annually to specifically train employees consistent with the permit requirement for employee education with the goal to improve and reinforce BMP practices for the site. As listed in Schedule A.1.j of the permit, this includes:

• Training must cover: − Specific control measures used to achieve the narrative technology based effluent limits, such as spill response procedures and good housekeeping practices. − Monitoring, inspection, reporting and documentation requirements. • Republic will ensure that the following personnel are trained and understand the facility’s specific requirements and their responsibilities: − Personnel who are responsible for the design, installation, maintenance, or repair of controls including, pollution prevention and treatment measures. − Personnel responsible for the storage and handling of chemicals and materials that could contribute pollutants to stormwater. − Personnel who are responsible for conducting or documenting monitoring or inspections as required in Schedule B. − Personnel who are responsible for conducting and documenting corrective actions.

• Education and training must be documented and must occur:

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 3-8

− No later than 30 calendar days of hiring an employee who works in areas where stormwater is exposed to industrial activities or conducts duties related to the implementation of the SWPCP. − No later than 30 calendar days of change in duties for key personnel responsible for the tasks described above. − Annually thereafter.

• Education and training must be documented and include which specific employees received training. A log of training dates must kept on site and submitted to DEQ upon request.

A example of the Republic Services’ training materials, and Employee Sign-In Sheet to document the annual meeting can be found in Appendix E.

3.4 Non-Stormwater Discharge

Groundwater is collected from footings, foundations and pavement subdrains to maintain integrity of structures. Groundwater collected from the Main Building is commingled with the waste water collected from the compactors and discharged via the sanitary sewer. Groundwater collected from Bay 3/4 and the Maintenance Building is commingled with stormwater and discharged via Discharge Points 001 or 007.

In addition, MSS generates wash water in its truck wash area. Wash water from the vehicle washing operations is directed to an OWS before discharging to the city sanitary sewer system. Because the wash area is covered, it is unlikely that the wash water from these operations will affect stormwater discharge at the facility.

3.5 Sector-Specific Narrative Technology Based Effluent Limits

There are no additional sector-specific narrative technology based effluent limits described for Sector K of the 1200-Z permit (pp. 82-84).

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 3-9

4 SPILL PREVENTION AND RESPONSE PROCEDURES

This section identifies areas where potential spills of materials can impact stormwater runoff, and their associated drainage points. Methods to prevent spills together with cleanup and notification procedures are also identified. Details of the site spill prevention activities are outlined below but are contained in the Spill Prevention, Control, and Countermeasure Plan, Metro South Station (Landau, 2018) attached as Appendix H. The entire SPCC should be reviewed by site personnel and the pollution prevention team. Procedures outlined in that plan should be followed if a spill occurs.

4.1 Potential Spill Areas

Oils, greases, and fuels used in vehicles and equipment could contaminate stormwater runoff. All four outfalls from the processing site have potential for this contamination.

Household hazardous wastes are accepted and processed at the HHWF, but on occasion spotters and load checkers in Bays 1, 2 and 3 will find and remove hazardous waste found in the MSW drop off areas. These activities create a potential for spill at all four outfalls. Proper oil handling and spill response training is provided to employees to help prevent these types of releases.

Spills are possible on the entire site. Contamination could reach any of the four outfalls. Spill kits are positioned around the site for quick and efficient response to incidents; spill kit locations are indicated on Figure 2.

4.2 Spill Prevention

Fuels and oils used for equipment maintenance are equipped with secondary containment or are stored inside buildings. Equipment is regularly maintained to reduce the number of fuel and oil leaks. Waste accepted at the site is off loaded under cover in designated unloading areas. Staff is trained annually on methods of safely handling and moving materials on site. Accidental spills will be cleaned up immediately.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 4-1

4.3 Spill Response

If significant materials or wastes are spilled and pose a threat to the stormwater system, employees must immediately notify the Operations Supervisor. The Operations Supervisor will assess the spill for the appropriate response:

• Small spills will be managed on site with absorbent, which can contain and soak up liquid on pavement.

• Larger spills will be managed by placing a dike around the nearest stormwater catch basin down gradient of the spill. The Operations Supervisor will assess the contained material for the appropriate clean up options.

• If the spill is on grass, soil, or rock, absorbent will be used to cover as much of the spill as possible, and clean-up activities will begin immediately.

During the emergency, the Operations Supervisor will work to prevent the incident from spreading or occurring in other areas of the site. If appropriate, the Operations Supervisor will temporarily stop facility operations if this will reduce the potential for further impact.

The following instructions will be followed by employees in real or potential emergency situations:

• Employees will notify the Operations Supervisor or his/her designee or a member of the MSS emergency response team as soon as a potential emergency is recognized.

• The first emergency response person at the scene will immediately assess the potential hazard. If the situation is considered an emergency that cannot be controlled by on-site personnel, off-site spill response will be called (911). If site personnel can handle the emergency, the response will be consistent with this section.

• The Operations Supervisor will direct on-scene management and emergency response.

• Depending on the severity of the incident, the Operations Supervisor will notify the appropriate community response unit, state, or federal agencies as described below in “Spill Reports and Regulatory Notifications”.

• The Operations Supervisor will direct off-site spill response units to the scene and provide information about the facility.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 4-2

• Potential ignition sources will be extinguished. Storm drains or ditches near spills will be plugged or diked.

• Suitable aisle and roadway space will be maintained to allow unobstructed entry of emergency response units.

Absorbent used to control and soak up materials will be swept into piles and shoveled into containers. The containers, bags, drums, buckets, etc. will be labeled and evaluated for proper disposal options.

Spill Kits will be maintained on site in designated areas (see Figure 2 and the SPCC). The equipment will be used only for emergency response to spills and will be decontaminated or replaced immediately after each response.

After the incident, the Operations Supervisor will be responsible for recovering materials and wastes, including their proper handling, storage, and disposal. The Operations Supervisor will review the cause of the incident, the response actions, and the clean-up, and other pertinent issues or circumstances. The information will be used to evaluate the emergency procedures, training requirements, institutional controls, or any combination of these that may need to be modified to reduce the chance of such incidents from re- occurring. Within two weeks of this evaluation, a written report will be prepared and delivered to senior staff.

The Operations Supervisor will make this plan available to site employees and will coordinate appropriate training for its proper implementation.

4.4 Spill Reports and Regulatory Notifications

In this section, “immediate notification of the Operations Supervisor” means as soon as it is safe to do so. Employees will warn fellow employees of a spill before notifying the Operations Supervisor if hazards or risks exist, evacuation is advisable, or prompt spill response actions may mitigate the problem.

If an incident arises that may adversely impact stormwater runoff, the Operations Supervisor (or his designee) will immediately call the Oregon Emergency Response System (800-452-0311) and the National Response Center (800-424-8802). When reporting the incident the following information will be provided:

• Name and telephone number of person reporting the incident

• Name and address of the facility

• Time, date, and duration of the incident

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 4-3

• Type of incident

• Quantity and type of hazardous material involved

• Number of persons, if any, exposed or injured

• Potential off-site hazards to human health or the environment

Spills must be documented in writing by the Operations Supervisor within a reasonable amount of time. The written report will be submitted to senior staff for review. If the Operations Supervisor believes that there may be an off-site threat, the appropriate local authorities will be notified. A release Incident Report Form is located in Appendix D

If required by the EPA or DEQ, the written report detailing the incident will be sent to the EPA regional administrator and the DEQ within 15 working days of the incident.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 4-4

5 INSPECTIONS AND RECORD KEEPING

5.1 Inspections

The facility will be inspected on a monthly basis when the facility is in operation, and include areas where industrial materials or activities are exposed to stormwater and areas where stormwater control measures, structures, catch basins, or treatment facilities are located. Visual observations must be conducted during a discharge event if one occurs during the month, regardless of whether the monthly site inspection has already occurred.

A separate inspection protocol is required by the SPCC for the fuel and petroleum liquids storage facilities as described in that document (examples of those forms are provided in Appendix D). For this SWPCP, all discharge points and the following items will be checked as part of facility inspections:

• Industrial materials, residue, or trash that may have or could come into contact with stormwater.

• Leaks or spills from industrial equipment, drums, tanks, and other containers.

• Offsite tracking of industrial or waste materials, or sediment where vehicles enter or exit the site, excluding employee only entrances and exits.

• Tracking or blowing of raw, final, or waste materials that results in exposure of stormwater falling on the site.

• Evidence of, or the potential for, pollutants entering the drainage system.

• Evidence of pollutants discharging to receiving waters at each discharge point.

• Visual observation for the presence of floating, suspended or settleable solids, color, odor, foam, visible oil sheen, or other obvious indicators of pollution in the stormwater discharge at each discharge point(s), including discharge points that have been authorized to be substantially similar in accordance with permit Schedule B.2.c.ii.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 5-1

• Conduct visual observations during regular business hours of operation and safe conditions.

• Stormwater control measures, including treatment, to ensure they are functioning properly.

Inspections will be conducted by personnel that have completed employee training and are familiar with these aspects of the SWPCP. Information will be documented on a Visual Monitoring - Monthly Inspection Form (Appendix D) and maintained as described below.

5.2 Record Keeping

Metro and Republic will keep the following information on file at the site:

• A copy of the SWPCP and any revisions, including revised stamped SWPCP from Tier II corrective action.

• A copy of the permit.

• Permit assignment letter and coverage documents from DEQ for the current permit term and any revisions thereto.

• Documentation of maintenance and repairs of control measures and treatment systems.

• Tier I reports.

• Inspection reports.

• Documentation of any benchmark exceedance and corrective action taken.

• Copies of any reports or corrective action submitted to the DEQ.

• Spills or leaks of significant materials (See Permit Schedule D.3, Definitions) that impacted or had the potential to impact stormwater or surface waters. Include the corrective actions to clean up the spill or leak as well as measures to prevent future problems of the same nature.

• Discharge Monitoring Reports, laboratory reports and field sampling notes.

• Employee education materials and records of training.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 5-2

Records will be retained by Republic for at least three (3) years and will be available to the DEQ on request.

Additionally, reports on spills of oil or hazardous substances in greater than “Reportable Quantities” including the following: oils, gasoline or diesel fuel, that causes a violation of the State of Oregon Water Quality Standards will be retained on file for a period of five years.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 5-3

6 STORMWATER MONITORING, DATA EVALUATION AND REPORTING

Stormwater monitoring, data evaluation, and reporting will follow the requirements specified in Schedule A.9, A.10, and Schedule B of the permit. The following sections describe monitoring requirements, the procedure and time frame for evaluating the data against stormwater benchmarks or other standards, developing corrective action responses for benchmark exceedances or impairment pollutants, and reporting.

6.1 Monitoring

Republic staff or its environmental consultant will collect grab samples that are representative of the stormwater discharge from the site. Sampling procedures are described in Appendix F. Single grab samples will be collected consistent with permit Schedule B.2, from the following monitoring point:

• 006: sample from the west end of the detention/wet pond before water discharges to the 48-inch concrete pipe that conveys water west to off-site municipal storm sewer.

The sample will be taken at the monitoring point described above (see Figure 2). Grab samples must be representative of discharge and collected during the first 12 hours of the discharge event, which is a storm event or snowmelt resulting in an actual discharge from the site. If it is not practicable to collect the sample within this period, collect the sample as soon as practicable and provide documentation with the Discharge Monitoring Report why it was not practicable to take samples within the period.

The stormwater monitoring period is from July 1st to June 30th of the subsequent year. Samples will be taken at least 14 days apart. Two samples will be collected between July 1 and December 31, and two samples between January 1 and June 30. Samples will be analyzed for the following parameters:

6.2 Data Evaluation and Tier I Corrective Action Response

Laboratory monitoring results will be compared with the benchmarks and reference concentrations listed above. Benchmarks are guideline concentrations, not limitations. They are designed to assist Republic in determining whether implementation of the SWPCP reduces pollutant concentration to below levels of concern.

After each monitoring event, Republic will compare sampling results with the benchmarks and reference concentrations for impairment pollutants. If water quality criteria are not achieved, Republic will review the SWPCP no later than 30 calendar days of receiving monitoring results, and identify any additional technically and economically feasible control measures that could be implemented to further improve the quality of stormwater discharges. These control measures could include BMPs, spill prevention and response procedures, preventative maintenance, and employee education procedures. Tier I Corrective Action Response (Permit Section A.10) will include the following:

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 6-2

• Investigate the cause of the elevated pollutant levels, which could include planning or conducting any needed pollutant source tracing activities. Available resources for the investigation include currently available guidance from the DEQ, other state agencies or the EPA, or the International Stormwater Best Management Practices (BMP) Database.

• Review the SWPCP and the selection, design, installation and implementation of control measures to ensure compliance with the permit and manufacturers’ specifications. Evaluate whether any previous removal or pollutant source isolation actions are complete and whether additional removal or modifications to pollutant source isolation are necessary. Evaluate any treatment measures, including if they were properly installed, maintained and implemented, and whether maintenance, corrections, or modifications to treatment measures are necessary.

• If additional control measures or other changes are necessary based on corrective action review, revise the SWPCP and submit the revised pages of the SWPCP to DEQ, including a schedule for implementing the control measures.

• Summarize the following information in a Tier I report that is retained on site and submit to the DEQ upon request: − Results of the investigation − Corrective actions taken or to be taken, including corrective actions completed or expected to be completed. Where corrective action is determined not to be necessary, provide the basis for this decision. − Document whether SWPCP revisions are necessary.

• Implement corrective actions before the next storm event, if possible, or no later than 30 calendar days after receiving the monitoring results, whichever comes first. If the corrective action cannot be completed within this time frame, the reasoning should be documented in the Tier 1 Report, and corrective actions must be completed as soon as practicable.

Results of the Tier I Corrective Action Response will be maintained in Appendix G of this SWPCP. Tier I reports prepared for exceedances of reference concentrations for impairment pollutants will be submitted to the DEQ no later than 60 calendar days after receiving monitoring results.

6.3 Tier II Corrective Action

In the last permit cycle, MSS implemented a Tier II Corrective Action based on the fourth year geometric mean exceedance under permit coverage that ended June 2012. That

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 6-3

action incorporated the detention/wet pond west of the site into its water quality treatment train, discontinued sampling at Discharge Points 001, 004, 005 and 007, and installed a new sampling point at the outfall from the detention/wet pond (006). Use of the detention/wet pond was technically evaluated by Wallis Engineering; their report was previously provided to the DEQ.

For the current permit cycle, the permit assignment letter (DEQ, 2018) specified that benchmark monitoring data collected at MSS during the July 2018 to June 2019 monitoring year be used to calculate the "Second Year Geometric Mean Benchmark Evaluation" as described in Schedule A.11 of the permit. Results of this evaluation will be submitted as part of the 4th Quarter Discharge Monitoring Report (DMR) to be submitted by August 15, 2019. Republic is not required to conduct this evaluation for the benchmark parameters(s) for which DEQ has granted a monitoring waiver consistent with Schedule B.4 of the permit. For reference, corrective response actions and deadlines to any benchmark exceedance are explained in Schedule A.11 of the permit.

6.4 Numeric Effluent Limit Guideline Evaluation

Numeric Effluent Limits are not applicable to this site. Information about these limits can be found at Schedule A.2 and Schedule B.1.c of the permit.

6.5 Reporting

Report information below will be submitted to the Northwest Region office of the DEQ:

DEQ Northwest Region 700 NE Multnomah Street, Suite 600 Portland, Oregon 97232

A summary of comprehensive reporting requirements is provided in Table 7 of the revised permit and should be referenced for detailed information. This subsection focuses on the common reporting requirements required of Metro.

Monitoring Data. Metro will submit grab sample data quarterly for the preceding calendar quarter as outlined in Table 6-2. The results will be listed on the standard DMR form available on the DEQ’s stormwater web site in Excel© format (see example copy in Appendix C). The report must show the minimum detection level and analytical methods for the parameters analyzed. Non-detections will be reported as “ND” with the detection limit in mg/L in parentheses, e.g., ND (0.005 mg/L). For all statistical calculations (i.e., for the compliance evaluation described in Section 6.2), one-half the method reporting limit will be used for non-detections.

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 6-4

A cover letter to the report will discuss whether any difficulties in sampling procedures occurred or to request a monitoring variance (e.g., whether a monitoring point was dry during a substantial portion of the year). Laboratory reports, supporting quality assurance data, and field pH measurements and calibration information will be attached to the DMR submittal.

PERMIT COVERAGE AND EXCLUSION FROM COVERAGE

1. New Discharger to Impaired Waters (see Schedule D.3, Definitions) a. A new discharger to an impaired water without a Total Maximum Daily Load (TMDL), based on the EPA-approved 303(d) list (Category 5) that is in effect on May 1, 2017, for pollutant(s) must meet one of the following conditions to obtain coverage under this permit: i. Prevent all pollutants for which the waterbody is impaired from exposure to stormwater and document in the Stormwater Pollution Control Plan (SWPCP) procedures taken to prevent exposure on-site; or ii. Document in SWPCP that the pollutant(s) for which the waterbody is impaired are not present at the site; or iii. Provide data and other technical information that demonstrates that the discharge is not expected to cause or contribute to an exceedance of the water quality standard for which the waterbody is impaired at the point of discharge to the waterbody if the pollutant(s) for which the waterbody is impaired are likely to be present at the site and DEQ has not issued a TMDL for the pollutant(s). b. Prior to granting permit coverage to a new discharger to impaired waters without a TMDL, DEQ or agent will make a determination and document that one of the conditions in paragraph 1.a. has been satisfied. c. A new discharger that is unable to meet one of the conditions in paragraph 1.a. is ineligible for coverage under this permit; either the discharge must cease or the new discharger will be required to obtain coverage under an individual NPDES permit. d. A new discharger to an impaired water with a TMDL (based on the EPA-approved TMDLs as of May 1, 2017) may receive permit coverage under this permit under one of the following circumstances: i. The TMDL does not establish industrial stormwater wasteload allocations, the compliance with the terms and conditions of the permit is presumed consistent with the TMDL. ii. If the TMDL establishes industrial stormwater wasteload allocations, and if DEQ or agent determines that there are sufficient remaining wasteload allocations in the TMDL to allow for the new industrial stormwater discharge, then the new discharge may be authorized by this permit. e. If a new discharge to impaired waters is authorized by DEQ under this permit, DEQ or agent will establish any additional monitoring, site controls or compliance schedules as necessary. f. Instead of granting permit coverage to a new discharge under paragraph 1.d., DEQ may determine that coverage under an individual NPDES permit is necessary. g. Conditions 1.a and 1.f above do not apply if the waterbody is impaired for: i. Biological communities and no pollutant, including indicator or surrogate pollutants, is specified as causing the impairment; or ii. Temperature, hydrologic modifications, or impaired hydrology.

2. New Application for Permit Coverage Requirements a. The following conditions apply to: Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: July 31, 2022 Page 6 of 129

TECHNOLOGY BASED EFFLUENT LIMITATIONS

1. Narrative Technology-Based Effluent Limits The permit registrant must meet the following narrative technology based effluent limits and additional sector-specific limits in Schedule E of this permit, if applicable. a. Minimize exposure - Minimize exposure of manufacturing, processing, material storage areas, including loading and unloading, disposal, cleaning, maintenance and fixed fueling areas to rain, snow, snowmelt and runoff. To the extent technologically available and economically practicable and achievable in light of best industry practice, the permit registrant must do the following: i. Locate materials and activities indoors or protect them with storm resistant covers if stormwater from affected areas may discharge to surface waters. Acceptable covers include, permanent structures such as roofs or buildings and temporary covers such as tarps; ii. Use grading, berming, or curbing to divert stormwater away from these areas and prevent stormwater contamination; iii. Store all hazardous substances (see Schedule D.3, Definitions), petroleum/oil liquids, and other chemical solid or chemical liquid materials that have potential to contaminate stormwater within berms or other secondary containment devices to prevent leaks and spills. If the use of berms or secondary containment devices is not practicable, then store such substances in areas that do not drain off-site or into the storm sewer system; iv. Locate materials, equipment and activities in containment and diversion systems, including the storage of leaking or leak-prone vehicles and equipment awaiting maintenance, to prevent leaks and spills from contaminating stormwater; v. Use drip pans or absorbents under or around leaking or leak-prone vehicles/equipment or store indoors. Drain fluids from equipment and vehicles prior to on-site storage or disposal; vi. Perform all cleaning operations indoors, under cover or in bermed areas that prevent runoff and run-on and also captures overspray; vii. Clean up spills or leaks promptly using absorbents or other effective methods to prevent discharge of pollutants and use spill/overflow protection equipment; viii. Ensure that all wash water is managed indoors or in bermed areas, disposed into sanitary sewer or drain to a proper collection system such as a closed-loop system or vegetated area and does not discharge into the stormwater drainage system unless allowed under condition 8, authorized non-stormwater discharge. b. Oil and Grease - Employ oil/water separators, booms, skimmers or other methods to eliminate or minimize oil and grease contamination in stormwater discharges. c. Waste Chemicals and Material Disposal - Recycle or properly dispose of wastes to eliminate or minimize exposure of pollutants to stormwater.

Permit registrants must evaluate the sampling results collected during the second monitoring year of permit coverage and determine if the geometric mean of the qualifying samples collected at each monitored discharge point exceeds any applicable statewide benchmarks in Schedule A.9 of this permit. DEQ or agent will identify in the permit assignment letter the registrant’s Tier II evaluation year. The permit registrant must report the geometric mean of qualifying samples in the 4th quarter Discharge Monitoring Report due on August 15 of the second monitoring year of permit coverage. Permit registrants are not required to conduct this evaluation for the benchmark parameter(s) for which DEQ or agent has granted a monitoring waiver in accordance with Schedule B.4 of this permit. b. For the pH benchmark, Tier II corrective action requirements are triggered if 50 percent or more of qualifying samples during the first two monitoring years of permit coverage are outside of the pH benchmark range. c. For permit registrants that received new coverage under a previous industrial stormwater general permit (that is, the 1200-COLS, 1200-COLSB or 1200-Z) on or after July 1, 2016, time spent covered under the previous permit is included in determining the second year of permit coverage and other Tier II deadlines. d. The permit registrant must use all qualifying samples to calculate the geometric mean. e. If fewer than four qualifying samples were collected during the second monitoring year of permit coverage, qualifying sample results from the previous monitoring year may be used to obtain four consecutive values for the Tier II calculation. f. If the geometric mean of the qualifying sampling results for any monitored discharge point exceeds any applicable statewide benchmark in Schedule A.9 of this permit (or if 50 percent or more of any pH sampling results for any monitored discharge point are outside of the pH benchmark range), permit registrant must submit a Tier II report, a Tier II mass reduction waiver request, or a Tier II natural background waiver request, along with associated revisions of the SWPCP, to DEQ or agent no later than December 31 of the third year of permit coverage, unless a later date is approved in writing by DEQ or agent. DEQ or agent will notify permit registrant within 60 calendar days of receipt if the Tier II corrective action response is accepted or denied. g. Tier II corrective action(s) or mass reduction action(s) must be installed and implemented no later than June 30 of the fourth monitoring year, unless DEQ or agent approved a later date in writing. If the permit registrant changes the specifics of the corrective actions before implementation, revisions must be submitted and accepted by DEQ or agent before implementation. Corrective action revisions do not change the implementation deadline. h. No later than 30 calendar days from implementing all Tier II corrective actions or mass reduction measures, the permit registrant must submit written confirmation to DEQ or agent with the date Tier II corrective action response was implemented in accordance with the revised approved SWPCP. i. Properly apply and size approved Tier II corrective action responses and mass reduction measures to all substantially similar discharge points. j. Tier II Report i. The Tier II report must include a proposal for active or passive treatment. This may include a combination of source removal, control and treatment measures, with the goal of achieving Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: July 31, 2022 Page 21 of 129

the benchmark(s) in Schedule A.9 of this permit. The report must include the rationale for the selection of the control and treatment measures, the projected reduction of pollutant concentration(s) and the schedule for implementing these measures. ii. An Oregon registered professional engineer (PE) must design and stamp the portion of the SWPCP that addresses these control measures. iii. At discharge points where Tier II has been implemented: (1) Permit registrants must take Tier I corrective actions in accordance with A.10. (2) Monitoring must resume at substantially similar discharge points. (3) Permit registrants may request a monitoring waiver if the geometric mean of four consecutive qualifying samples is equal to or below the benchmark. k. Tier II Mass Reduction Waiver i. A permit registrant may request a mass reduction waiver from the requirements in Schedule A.11.j above if the permit registrant implements or has implemented volume reduction measures, such as low impact development practices, that will or has resulted in reductions of the mass load of pollutants in the discharge below the mass equivalent of the applicable statewide benchmarks in Schedule A.9 of this permit. ii. The mass reduction waiver request and the revised SWPCP must include data and analysis to support the rationale for the mass load reduction selection. Include in the waiver request a description of the measure(s), and a mass load analysis, and expected implementation date(s). iii. An Oregon Professional Engineer (PE) or Oregon certified engineering geologist (CEG) must design and stamp the portion of the SWPCP that addresses the mass reduction measures. iv. At discharge points at which a Tier II mass reduction waiver has been implemented: (1) Permit registrants must take Tier I corrective actions in accordance with A.10. (2) Monitoring must resume at substantially similar discharge points. (3) Permit registrants may request a monitoring waiver if the geometric mean of four consecutive qualifying samples is equal to or below the benchmark. l. Tier II Natural Background Waiver i. A permit registrant may request a natural background waiver from the requirements in Schedule A.11.j above if the benchmark exceedance(s) is attributed solely to the presence of the pollutant(s) in natural background and is not associated with industrial activities at the site (see Schedule D.3, Definitions). The Tier II natural background waiver request must include the investigation and analysis used to demonstrate that the exceedances are due only to natural background conditions and data collected by the permit registrant or others (including peer-reviewed literature studies) that describe the levels of natural background pollutants in the discharge.

12. Permit Compliance a. Any noncompliance with any of the requirements of this permit constitutes a violation of the Clean Water Act. b. Any corrective actions and time periods specified for remedying noncompliance with the permit do not absolve permit registrants of the initial underlying violations. c. Where corrective action is triggered by an event that does not itself constitute a violation, such as a benchmark exceedance, there is no permit violation associated with the trigger event provided that the permit registrant takes the corrective action within the deadlines identified in this permit. Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: July 31, 2022 Page 22 of 129

d. A new permit registrant with a new facility (that begins operation after August 1, 2017) or an existing facility (that was in operation before August 1, 2017, without a stormwater discharge permit) must implement stormwater control measures to meet new technology and water quality based requirements in Schedule A.1 – A.5, including applicable sector-specific requirements in Schedule E of this permit, no later than 90 calendar days after receiving permit coverage. Control measures that require capital improvements must be completed no later than two years after receiving permit coverage, unless DEQ or agent approved a later date.

13. Corrective Action Triggers The permit contains many types of corrective action triggers: statewide benchmarks, sector- specific benchmarks, numeric effluent limits and impairment reference concentrations. The numeric value of the corrective action trigger for a particular pollutant is often different for different types of triggers. For a particular facility, multiple corrective action triggers may apply for a particular pollutant. When exceeding multiple applicable corrective action triggers, the permit registrant must follow the corrective actions for each trigger.

SCHEDULE B

MONITORING REQUIREMENTS

1. Pollutant Parameters a. Benchmarks - Permit registrants must monitor for the applicable statewide benchmark pollutants identified in Schedule A.9 of this permit. Permit registrants must also monitor for benchmarks specified for applicable industrial sector(s) identified in Schedule E, for both primary industrial activity and any co-located industrial activities. b. Impairment Pollutants i. Permit registrants that discharge to impaired waterbodies, based on the EPA-approved 303(d) list (Category 5) that is in effect as of May 1, 2017, (see Schedule D.3, Definitions) for pollutant(s), must monitor for impairment pollutant(s) identified in the permit assignment letter for which a standard analytical method exists (see 40 CFR Part 136). ii. Before granting coverage under this permit, DEQ or agent will identify in the permit assignment letter the impairment pollutants that the permit registrant is required to monitor and reference concentrations for these pollutants. Reference concentrations reflect the approved acute aquatic life criterion for the pollutant when applicable. If there is not an acute criterion for the pollutant, DEQ or agent will use an applicable chronic criterion. If there is not a chronic criterion for the pollutant, DEQ or agent will use an applicable human health criterion. (1) If the pollutant for which the waterbody is impaired is suspended solids, turbidity or sediment/sedimentation, permit registrants must monitor for Total Suspended Solids (TSS). (2) If the pollutant for which the waterbody is impaired is expressed in the form of an indicator or surrogate pollutant, permit registrants must monitor for that indicator or surrogate pollutant. (3) No monitoring is required when a waterbody’s impairment is due to one of the following: Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: July 31, 2022 Page 23 of 129

(A) Biological communities and no pollutant, including indicator or surrogate pollutants, is specified as causing the impairment; or (B) Temperature, hydrologic modifications, or impaired hydrology. iii. Permit registrants must meet Schedule B.1.b.i. unless the permit registrant: (1) Prevents all pollutants for which the waterbody is impaired from being exposed to stormwater, and documents in the SWPCP those procedures it has taken to prevent exposure on site; or (2) Provides monitoring data demonstrating that the pollutant(s) for which the waterbody is impaired are not present in the discharge. c. Numeric Effluent limits pursuant to Federal Effluent Limit Guidelines - Permit registrants subject to effluent limit guidelines must monitor for the parameters in Schedule A.2 of this permit at each discharge point containing the discharges from industrial activities identified in the guidelines and report the monitoring results in the Discharge Monitoring Report required by Schedule B.8. d. Multiple Requirements - When more than one type of monitoring for the same pollutant at the same discharge point applies, the permit registrant may use a single sample to satisfy both monitoring requirements. Permit registrant must complete corrective action and reporting requirement for each parameter.

2. Sampling Procedures a. Grab Sampling i. For each discharge point monitored, collect a single grab sample of stormwater discharge or a series of composite samples. ii. Composite samples may be used as an alternative to grab sampling, except when monitoring for pH, oil and grease and E. coli. Composited samples must be collected from same storm event. Registrants may not switch between grab sampling to composite sampling during a monitoring year without DEQ or agent approval. iii. Permit registrants may use a single grab sample or composite to satisfy multiple pollutant parameter monitoring requirements (for example, required to monitor for zinc as benchmark and impairment pollutant). b. Representative Sample i. Samples must be representative of the discharge. ii. Monitoring locations must be identified in the SWPCP. iii. Stormwater discharges regulated by this permit include stormwater run-on that commingles with stormwater discharges associated with industrial activity. iv. If discharges authorized by this permit commingle with discharges authorized under a separate NPDES permit, any required sampling of the authorized discharges must be performed at a point before they mix with other waste streams, to the extent practicable. When combined flows are unavoidable, sampling must include all permitted parameters. v. Authorized non-stormwater discharges under condition 8 of this permit must be sampled when commingled with stormwater discharges associated with industrial activity. vi. Stormwater flows may combine into a common on-site treatment facility. vii. The permit registrant shall, to the extent practicable, sample stormwater associated with industrial activity as it flows off-site before it combines with stormwater, wastewater or other waste streams from another facility or mixes with any surface water. c. Multiple Discharges - Each discharge point must be monitored unless: Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: July 31, 2022 Page 24 of 129

i. Discharge point serves an area without exposure of stormwater to industrial activities; or ii. Discharge point has effluent that is substantially similar to the effluent(s) of a monitored discharge point and the same BMPs are implemented and maintained at the substantially similar discharge points or drainage areas that lead to the discharge points. Substantially similar effluent(s) are discharges from drainage areas serving comparable activities where the discharges are expected to be similar in composition. The determination of substantial similarity of effluent(s) must be based on past monitoring data or an analysis supporting that the discharge points are substantially similar. The supporting data or analysis must be included in the SWPCP. This provision does not apply to discharge point(s) covered by a numeric effluent limit. d. Timing - Monitor the discharge during the first 12 hours of the discharge event, which is a storm event or snowmelt resulting in an actual discharge from a site. If it is not practicable to collect the sample within this period, collect the sample as soon as practicable and provide documentation with the Discharge Monitoring Report why it was not practicable to take samples within the period. Permit registrant is not required to sample outside of regular business hours of operation or during unsafe conditions. e. Sampling for pH - Approved methods for pH sampling require either measuring the pH directly in the flow, or analyzing the sample within 15 minutes of sample collection. i. Obtain accurate pH readings with a properly calibrated pH meter. ii. Permit registrant must follow manufacturers’ specifications and keep meter in good working order. iii. pH paper may not be used for determining the precise parameters established in this permit. f. Monitoring Frequency - Permit registrants must monitor their stormwater discharge according to the frequency described in Table 5 below unless DEQ or agent grant a monitoring waiver in writing or approve a monitoring variance. i. Stormwater samples must be collected at least 14 calendar days apart. ii. Permit registrant may collect more samples than the minimum frequency described below, but must report this additional data in the Discharge Monitoring Report. All qualifying samples must be included to establish a monitoring waiver in Schedule B.4 or to conduct the geometric mean evaluation in Schedule A.11 of this permit. iii. Exceedance of Numeric Effluent Limit in Schedule A.2 of this permit – Permit registrants must conduct follow-up monitoring of any pollutant that exceeds the numeric effluent limit(s) no later than 30 calendar days (or during the next storm event should none occur within 30 calendar days) of receiving the monitoring results. If the follow-up monitoring exceeds the numeric effluent limit, the permit registrant must monitor the discharge four times per year until compliance with the numeric effluent limit is achieved. Once monitoring achieves the effluent limit value, semi-annual frequency may resume.

3. Monitoring Variance a. Permit registrants may request a monitoring variance for missed samples due to no storm events of sufficient magnitude to produce run-off during regular business hours of operation and safe conditions. For each missed sample, variance requests are due on February 15 and August 15. Report no discharge in the Discharge Monitoring Report and include supporting data and analysis demonstrating why the monitoring did not occur at the time of DMR submission. If DEQ or agent has evidence contradicting the permit registrant’s no discharge claim, failure to complete the required monitoring may be a permit violation. Supporting data may include: i. State or federal authorities declared the year a drought year. ii. Demonstration that rainfall in the area where the permit registrant’s facility is located was 20 percent or more below the three-year average rainfall for that area. iii. Photo documentation, rain gauge data, detention basin storage volumes, storm infiltration rate or retention capacity.

4. Monitoring Waiver for Benchmark and Impairment Pollutant Monitoring a. A monitoring waiver may be requested from DEQ or agent in the following circumstances: i. When the benchmark or impairment reference concentration has been achieved, as demonstrated by: (1) The geometric mean of four consecutive qualifying samples is equal to or below the impairment reference concentration, applicable statewide or sector-specific benchmarks. (2) pH results are within the range for four consecutive qualifying readings. (3) For Tier II parameters and discharge points once the corrective action has been implemented, and the geometric mean of four consecutive qualifying samples is equal to or below the applicable statewide benchmark, or pH results are within the range for four consecutive readings. ii. If the exceedance(s) is attributed solely to the presence of the pollutant(s) in natural background and is not associated with industrial activities at the site. Permit registrant may submit a natural background waiver report to DEQ or agent that describes the investigation and analysis to demonstrate that the exceedances are due to natural background conditions and includes any data collected by the permit registrant or others (including peer-review literature studies) that describe the levels of natural background pollutants in the discharge. Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: July 31, 2022 Page 26 of 129

iii. If a facility is inactive and unstaffed and no industrial materials or activities are exposed to stormwater, the permit registrant is not required to conduct monitoring for the remainder of the permit term. (1) Permit registrant must provide documentation with the Discharge Monitoring Report indicating that the site is inactive and unstaffed, and that there are no industrial materials or activities exposed to stormwater, in accordance with the substantive requirements in 40 CFR 122.26(g)(4)(iii). (2) Sign and certify the statement in accordance with D8 in Schedule F of this permit. b. The permit registrant’s request must include documentation to support the request. Monitoring waivers may be allowed for individual parameters and separate discharge points. c. If the facility has triggered Tier II during this permit term, permit registrants are ineligible for monitoring waivers at all discharge points and parameters that exceeded the geometric mean in Schedule A.11. The ineligibility applies to the end of second monitoring year through Tier II implementation date. d. DEQ or agent will notify the permit registrant in writing if a monitoring waiver is approved or denied. Until written approval of the monitoring waiver is received, the permit registrant must continue monitoring. e. Monitoring waivers are valid for the remainder of the permit term. Upon renewal into a subsequent permit, permit registrants must reinstate all monitoring, and re-establish the basis for all monitoring waivers. f. There is no reduction in monitoring allowed for: i. Visual observations, unless the site is inactive or unstaffed and there are no industrial materials or activities exposed to stormwater and permit registrant meets requirements in Schedule B.4.a.iii of this permit. ii. Monitoring for federal numeric effluent limit guidelines. g. Reinstatement of Monitoring i. It is the responsibility of the permit registrant to reinstate discharge monitoring under the following circumstances or if notified by DEQ or agent: (1) Prior monitoring used to establish the monitoring waiver was improper or sampling results were incorrect; (2) Changes to site conditions are likely to affect stormwater discharge characteristics, such as change in SIC code, process change or increased pollutants sources exposed to stormwater; (3) Additional monitoring occurs and the sampling results exceed benchmark(s) or impairment reference concentration(s); or (4) For inactive or unstaffed sites, the facility becomes active or staffed, or industrial materials or activities become exposed to stormwater. h. Revocation of Monitoring Waiver DEQ or agent may revoke the monitoring waiver based on any of the above conditions or in response to an inspection or corrective action. In this event, DEQ or agent will notify the permit registrant in writing that the monitoring waiver is revoked.

5. Additional Monitoring- DEQ may notify permit registrants in writing of additional discharge monitoring requirements. Any such notice will state the reasons for the monitoring, locations and Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: July 31, 2022 Page 27 of 129

Schedule E – Sector-Specific Requirements for Industrial Activity Sector F – Primary Metal

E.F.1 Additional Technology-Based Effluent Limits E.F.1.1 Good Housekeeping Measures. As part of your good housekeeping program, include a cleaning and maintenance program for all impervious areas of the facility where particulate matter, dust, or debris may accumulate, especially areas where material loading and unloading, storage, handling, and processing occur; and, where practicable, the paving of areas where vehicle traffic or material storage occur but where vegetative or other stabilization methods are not practicable (institute a sweeping program in these areas too). For unstabilized areas where sweeping is not practicable, consider using stormwater management devices such as sediment traps, vegetative buffer strips, filter fabric fence, sediment filtering boom, gravel outlet protection, or other equivalent measures that effectively trap or remove sediment.

E.F.2 Additional SWPCP Requirements E.F.2.1 Drainage Area Site Map. Identify in the SWPCP where any of the following activities may be exposed to precipitation or surface runoff: storage or disposal of wastes such as spent solvents and baths, sand, slag and dross; liquid storage tanks and drums; processing areas including pollution control equipment (e.g., baghouses); and storage areas of raw material such as coal, coke, scrap, sand, fluxes, refractories, or metal in any form. In addition, indicate where an accumulation of significant amounts of particulate matter could occur from such sources as furnace or oven emissions, losses from coal and coke handling operations, etc., and could result in a discharge of pollutants to waters of the United States.

E.F.2.2 Inventory of Exposed Material. Include in the inventory of materials handled at the site that potentially may be exposed to precipitation or runoff, areas where deposition of particulate matter from process air emissions or losses during material-handling activities are possible.

E.F.3 Additional Inspection Requirements As part of conducting your monthly inspections address all potential sources of pollutants, including (if applicable) air pollution control equipment (e.g., baghouses, electrostatic precipitators, scrubbers, and cyclones), for any signs of degradation (e.g., leaks, corrosion, or improper operation) that could limit their efficiency and lead to excessive emissions. Consider monitoring air flow at inlets and outlets (or use equivalent measures) to check for leaks (e.g., particulate deposition) or blockage in ducts. Also inspect all process and material handling equipment (e.g., conveyors, cranes, and vehicles) for leaks, drips, or the potential loss of material; and material storage areas (e.g., piles, bins, or hoppers for storing coke, coal, scrap, or slag, as well as chemicals stored in tanks and drums) for signs of material losses due to wind or stormwater runoff.

Schedule E – Sector-Specific Requirements for Industrial Activity Sector G – Metal Mining

E.G.1 Covered Stormwater Discharges The requirements in Sector G apply to stormwater discharges associated with industrial activity from Metal Mining facilities, including mines abandoned on Federal lands, as identified by the SIC Codes specified under types of industrial sources required to obtain coverage, Table 1. Coverage is required for metal mining facilities that discharge stormwater contaminated by contact with, or that has come into contact with, any overburden, raw material, intermediate product, finished product, byproduct, or waste product located on the site of the operation. E.G.1.1 Covered Discharges from Inactive Facilities. All stormwater discharges. E.G.1.2 Covered Discharges from Active and Temporarily Inactive Facilities. Only the stormwater discharges from the following areas are covered:  Waste rock and overburden piles if composed entirely of stormwater and not combined with mine drainage;  Topsoil piles;  Offsite haul and access roads;  Onsite haul and access roads constructed of waste rock, overburden or spent ore if composed entirely of stormwater and not combining with mine drainage;  Onsite haul and access roads not constructed of waste rock, overburden or spent ore except if mine drainage is used for dust control;  Runoff from tailings dams or dikes when not constructed of waste rock or tailings and no process fluids are present;  Runoff from tailings dams or dikes when constructed of waste rock or tailings and no process fluids are present, if composed entirely of stormwater and not combining with mine drainage;  Concentration building if no contact with material piles;  Mill site if no contact with material piles;  Office or administrative building and housing if mixed with stormwater from industrial area;  Chemical storage area;  Docking facility if no excessive contact with waste product that would otherwise constitute mine drainage;  Explosive storage;  Fuel storage;  Vehicle and equipment maintenance area and building;  Parking areas (if necessary);  Power plant;  Truck wash areas if no excessive contact with waste product that would otherwise constitute mine drainage;  Unreclaimed, disturbed areas outside of active mining area;  Reclaimed areas released from reclamation requirements prior to December 17, 1990;  Partially or inadequately reclaimed areas or areas not released from reclamation requirements. Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 54 of 129

E.G.1.3 Covered Discharges from Earth-Disturbing Activities Conducted Prior to Active Mining Activities. All stormwater discharges. E.G.1.4 Covered Discharges from Facilities Undergoing Reclamation. All stormwater discharges. E.G.2 Limitations on Coverage E.G.2.1 Prohibition of Stormwater Discharges. Stormwater discharges not authorized by this permit: discharges from active metal mining facilities that are subject to effluent limitation guidelines for the Ore Mining and Dressing Point Source Category (40 CFR Part 440). Note: Stormwater runoff from these sources are subject to 40 CFR Part 440 if they are mixed with other discharges subject to Part 440. In this case, they are not eligible for coverage under this permit. Discharges from overburden/waste rock and overburden/waste rock-related areas are not subject to 40 CFR Part 440 unless they: (1) drain naturally (or are intentionally diverted) to a point source; and (2) combine with ''mine drainage'' that is otherwise regulated under the Part 440 regulations. For such sources, coverage under this permit would be available if the discharge composed entirely of stormwater does not combine with other sources of mine drainage that are not subject to 40 CFR Part 440. Operators bear the initial responsibility for determining if they are eligible for coverage under this permit, or must seek coverage under another NPDES permit. E.G.2.2 Prohibition of Non-Stormwater Discharges. Not authorized by this permit: adit drainage, and contaminated springs or seeps discharging from waste rock dumps that do not directly result from precipitation events.

E.G.3 Definitions The following definitions are not intended to supersede the definitions of active and inactive mining facilities established by 40 CFR 122.26(b)(14)(iii). E.G.3.1 Mining operation – For this permit, mining operations are grouped into two distinct categories, with distinct technology based effluent limits and requirements applicable to each: a) earth- disturbing activities conducted prior to active mining activities); and b) active mining activities, which includes reclamation. “Mining operations” can occur at both inactive mining facilities and temporarily inactive mining facilities. E.G.3.2 Earth-disturbing activities conducted prior to active mining activities – Consists of two classes of earth-disturbing (i.e., clearing, grading and excavation) activities: a. activities performed for purposes of mine site preparation, including: cutting new rights of way (except when related to access road construction); providing access to a mine site for vehicles and equipment (except when related to access road construction); other earth disturbances associated with site preparation activities on any areas where active mining activities have not yet commenced (e.g., for heap leach pads, waste rock facilities, tailings impoundments, wastewater treatment plants); and b. construction of staging areas to prepare for erecting structures such as to house project personnel and equipment, mill buildings, etc., and construction of access roads. Earth-disturbing activities associated with the construction of staging areas and the construction of access roads conducted prior to active mining are considered to be “construction” and have additional technology based effluent limits in E.G.4.2.

E.G.3.3 Active mining activities – Activities related to the extraction, removal or recovery, and benefication of metal ore from the earth; removal of overburden and waste rock to expose mineable minerals; and site reclamation and closure activities. All such activities occur within Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 55 of 129

the “active mining area.” Reclamation involves activities undertaken, in compliance with applicable mined land reclamation requirements, to return the land to an appropriate post- mining contour and land use in order to meet applicable federal and state reclamation requirements. In addition, once earth-disturbing activities conducted prior to active mining activities have ceased and all related requirements in E.G.4 have been met, and a well- delineated “active mining area” has been established, all activities (including any clearing, grading, and excavation) that occur within the active mining area are “active mining activities.” E.G.3.4 Active mining area – A place where work or other activity related to the extraction, removal or recovery of metal ore is being conducted, except, with respect to surface mines, any area of land on or in which grading has been completed to return the earth to desired contour and reclamation work has begun. Note: Earth-disturbing activities described in the definition in E.G.3.2 that occur on areas outside the active mining area (e.g., for expansion of the mine into undeveloped territory) are considered “earth-disturbing conducted prior to active mining activities”, and must comply with the requirements in E.G.4 E.G.3.5 Inactive metal mining facility – A site or portion of a site where metal mining and/or milling occurred in the past but there are no active mining activities occurring as defined above, and where the inactive portion is not covered by an active mining permit issued by the applicable state or federal agency. An inactive metal mining facility has an identifiable owner / operator. Sites where mining claims are being maintained prior to disturbances associated with the extraction, beneficiation, or processing of mined materials and sites where minimal activities are undertaken for the sole purpose of maintaining a mining claim are not considered either active or inactive mining facilities and do not require an NPDES industrial stormwater permit. E.G.3.6 Temporarily inactive metal mining facility – A site or portion of a site where metal mining and/or milling occurred in the past but currently are not being actively undertaken, and the facility is covered by an active mining permit issued by the applicable State or Federal agency.

E.G.4 Requirements Applicable to Earth-Disturbing Activities Conducted Prior to Active Mining Activities Stormwater discharges from earth-disturbing activities conducted prior to active mining activities (defined in E.G.3.3) are covered under this permit. For such earth-disturbing activities, permit registrants do not need to comply the technology-based effluent limits or Schedule B, monitoring or inspection frequency in Schedule B or E.G.5, E.G.7 or E.G.8. Authorized discharges from areas where earth-disturbing activities have ceased and stabilization as specified in E.G.4.1.9 or E.G.4.2.11, where appropriate, has been completed (stabilization is not required for areas where active mining activities will occur), are no longer subject to E.G.4 requirements. At such time, authorized discharges become subject to all other applicable requirements in the permit, including not need to comply the technology-based effluent limits or Schedule B, monitoring or inspection frequency in Schedule B and Sector E.G.5, E.G.7 and E.G.8. E.G.4.1 Technology-Based Effluent Limits Applicable to All Earth-Disturbing Activities Conducted Prior to Active Mining Activities. The following technology-based effluent limits apply to authorized discharges from all earth-disturbing activities conducted prior to active mining activities defined in E.G.3. These limits supersede the technology-based limits listed in Schedule A.

E.G.4.1.1 Erosion and sediment control installation requirements.  By the time construction activities commence, install and make operational downgradient sediment controls, unless this timeframe is infeasible. If infeasible Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 56 of 129

you must install and make such controls operational as soon as practicable or as soon as site conditions permit.  All other stormwater controls described in the SWPCP must be installed and made operational as soon as conditions on each portion of the site allows.

E.G.4.1.2 Erosion and sediment control maintenance requirements. You must:  Ensure that all erosion and sediment controls remain in effective operating condition.  Wherever you determine that a stormwater control needs maintenance to continue operating effectively, initiate efforts to fix the problem immediately after its discovery, and complete such work by the end of the next work day.  When a stormwater control must be replaced or significantly repaired, complete the work within 7 days, unless infeasible. If 7 days is infeasible, you must complete the installation or repair as soon practicable. E.G.4.1.3 Perimeter controls. You must:  Install sediment controls along those perimeter areas of your disturbed area that will receive stormwater, except where site conditions prevent the use of such controls (in which case, maximize their installation to the extent practicable).  Remove sediment before it accumulates to one-half of the above-ground height of any perimeter control. E.G.4.1.4 Sediment track-out. For construction vehicles and equipment exiting the site directly onto paved roads, you must:  Install sediment controls along those perimeter areas of your disturbed area that will receive stormwater, except where site conditions prevent the use of such controls (in which case, maximize their installation to the extent practicable).  Remove sediment before it accumulates to one-half of the above-ground height of any perimeter control.  Note: DEQ recognizes that some fine grains may remain visible on the surfaces of off-site streets, other paved areas, and sidewalks even after you have implemented sediment removal practices. Such “staining” is not a violation of E.G.4.1.4. E.G.4.1.5 Soil or sediment stockpiles. You must:  Minimize erosion of stockpiles from stormwater and wind via temporary cover, if feasible.  Prevent up-slope stormwater flows from causing erosion of stockpiles (e.g., by diverting flows around the stockpile).  Minimize sediment from stormwater that runs off of stockpiles, using sediment controls (e.g., a sediment barrier or downslope sediment control). E.G.4.1.6 Sediment basins. If you intend to install a sediment basin to treat stormwater from your earth-disturbing activities, you must:  Provide storage for either (1) the 2-year, 24-hour storm, or (2) 3,600 cubic feet per acre drained.  Prevent erosion of (1) basin embankments using stabilization controls (e.g., erosion control blankets), and (2) the inlet and outlet points of the basin using erosion controls and velocity dissipation devices. E.G.4.1.7 Minimize dust. You must minimize the generation of dust through the appropriate application of water or other dust suppression techniques that minimize pollutants being discharged into surface waters. Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 57 of 129

E.G.4.1.8 Restrictions on use of treatment chemicals. If you intend to use sediment treatment chemicals at your site, you are subject to the following minimum requirements:  Use conventional erosion and sediment controls prior to and after application of chemicals;  Select chemicals suited to soil type, and expected turbidity, pH, flow rate;  Minimize the discharge risk from stored chemicals;  Comply with state/local requirements;  Use chemicals in accordance with good engineering practices and specifications of chemical supplier;  Ensure proper training;  Provide proper SWPCP documentation. If you plan to use cationic treatment chemicals, you are ineligible for coverage under this permit, unless you notify your applicable DEQ regional office or agent in advance and receive authorization under this permit after you have included appropriate controls and implementation procedures designed to ensure that your use of cationic treatment chemicals will not lead to a violation of water quality standards. E.G.4.1.9 Site stabilization requirements for earth-disturbing activities performed for purposes of mine site preparation as defined in E.G.3.2(a) (i.e., not applicable to construction of staging areas for structures and access roads as defined in E.G.3.2(b)). You must comply with the following stabilization requirements except where the intended function of the site accounts for such disturbed earth (e.g., the earth disturbances will become actively mined, or the controls implemented at the active mining area effectively control the disturbance) (although you are encouraged to do so within the active mining area, where appropriate):  Temporary stabilization of disturbed areas. Stabilization measures must be initiated immediately in portions of the site where earth-disturbing activities performed for purposes of mine site preparation (as defined in E.G.3.2(a)) have temporarily ceased, but in no case more than 14 days after such activities have temporarily ceased. In arid, semi-arid, and drought-stricken areas, or in areas subject to snow or freezing conditions, where initiating perennial vegetative stabilization measures is not possible within 14 days after earth-disturbing activities performed for purposes of mine site preparation has temporarily ceased, temporary vegetative stabilization measures must be initiated as soon as practicable. Until temporary vegetative stabilization is achieved, interim measures such as erosion control blankets with an appropriate seed base and tackifiers must be employed. In areas of the site where earth-disturbing activities performed for purposes of mine site preparation have permanently ceased prior to active mining, temporary stabilization measures must be implemented to minimize mobilization of sediment or other pollutants until active mining activities commence.  Final stabilization of disturbed areas. Stabilization measures must be initiated immediately where earth-disturbing activities performed for purposes of mine site preparation (as defined in E.G.3.2(a)) have permanently ceased, but in no case more than 14 days after the earth-disturbing activities have permanently ceased. In arid, semi-arid, and drought-stricken areas, or in areas subject to snow or freezing conditions, where initiating perennial vegetative stabilization measures is not possible within 14 days after earth-disturbing activities have permanently ceased, final vegetative stabilization measures must be initiated as soon as possible. Until Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 58 of 129

final stabilization is achieved, temporary stabilization measures, such as erosion control blankets with an appropriate seed base and tackifiers, must be used.

E.G.4.2 Additional Technology-Based Effluent Limits Applicable Only to the Construction of Staging Areas for Structures and Access Roads. The following technology-based effluent limits apply to authorized discharges from earth-disturbing activities associated with the construction of staging areas and the construction of access roads, as defined in E.G.3.2(b). These limits supersede the technology-based limits listed in Schedule B and E.G.5 of this sector. These limits do not apply to earth-disturbing activities performed for purposes of mine site preparation (as defined in E.G.3.2(a)). E.G.4.2.1 Area of disturbance. You must minimize the amount of soil exposed during construction activities. E.G.4.2.2 Erosion and sediment control design requirements. You must:  Design, install and maintain effective erosion and sediment controls to minimize the discharge of pollutants from earth-disturbing activities. Account for the following factors in designing your erosion and sediment controls: o The expected amount, frequency, intensity and duration of precipitation; o The nature of stormwater runoff and run-on at the site, including factors such as impervious surfaces, slopes and site drainage features; o The range of soil particle sizes expected to be present on the site.  Direct discharges from your stormwater controls to vegetated areas of your site to increase sediment removal and maximize stormwater infiltration, including any natural buffers, unless infeasible. Use velocity dissipation devices if necessary to prevent erosion when directing stormwater to vegetated areas.  If any stormwater flow becomes or will be channelized at your site, you must design erosion and sediment controls to control both peak flowrates and total stormwater volume to minimize channel and streambank erosion and scour in the immediate vicinity of discharge points.  If you install stormwater conveyance channels, they must be designed to avoid unstabilized areas on the site and to reduce erosion, unless infeasible. In addition, you must minimize erosion of channels and their embankments, outlets, adjacent streambanks, slopes, and downstream waters during discharge conditions through the use of erosion controls and velocity dissipation devices within and along the length of any constructed stormwater conveyance channel, and at any outlet to provide a non-erosive flow velocity. E.G.4.2.3 Natural Buffers. For any stormwater discharges from earth-disturbing activities within 50 feet of a water of the U.S., you must comply with one of the following compliance alternatives: 1. Maintain a 50-foot undisturbed natural buffer between earth-disturbing activities and the water of the U.S.; or 2. Provide an undisturbed natural buffer that is less than 50 feet, permit registrant must implement one or more of the BMPs listed below to control and treat sediment and turbidity:  Compost berms, compost blankets, or compost socks;  Erosion control mats;  Takifiers used in combination with perimeter sediment controls; Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 59 of 129

 Approved water treatment by electro-coagulation, flocculation, or filtration; and/or  Other substantially equivalent sediment or turbidity control measures approved by DEQ or agent. 3. Ensure all discharges are treated by control measures prior to entering the natural buffer. 4. Delineate and clearly mark off all natural buffers. There are exceptions when buffer requirements do not apply:  The natural buffer has already been eliminated by preexisting development disturbances;  The disturbance is for a water-dependent structure or earth-disturbing approved under a CWA section 404 permit. E.G.4.2.4 Soil or sediment stockpiles. In addition to the requirements in E.G.4.1.5, you must locate any piles outside of any natural buffers established under E.G.4.2.3. E.G.4.2.5 Sediment basins. In addition to the requirements in E.G.4.1.6, you must locate sediment basins outside of any surface waters and any natural buffers established under E.G.4.2.3, and you must utilize outlet structures that withdraw water from the surface, unless infeasible. E.G.4.2.6 Native topsoil preservation. You must preserve native topsoil removed during clearing, grading, or excavation, unless infeasible. Store topsoil in a manner that will maximize its use in reclamation or final vegetative stabilization (e.g., by keeping the topsoil stabilized with seed or similar measures). This requirement does not apply if the intended function of the disturbed area dictates that topsoil be disturbed or removed. E.G.4.2.7 Steep slopes. You must minimize the disturbance of steep slopes. The permit does not prevent or prohibit disturbance on steep slopes. Depending on site conditions and needs, disturbance on steep slopes may be necessary (e.g., a road cut in mountainous terrain; for grading steep slopes prior to erecting the mine office). Where steep slope disturbances are necessary, you can minimize the disturbances to steep slopes through the implementation of a number of standard erosion and sediment control practices, such as by phasing disturbances in these areas and using stabilization practices specifically for steep grades. E.G.4.2.8 Soil compaction. Where final vegetative stabilization will occur or where infiltration practices will be installed, you must either restrict vehicle/ equipment use in these areas to avoid soil compaction or use soil conditioning techniques to support vegetative growth. Minimizing soil compaction is not required where compacted soil is integral to the functionality of the site. E.G.4.2.9 Dewatering Practices. You are prohibited from discharging ground water or accumulated stormwater that is removed from excavations, trenches, foundations, vaults or other similar points of accumulation, unless such waters are first effectively managed by appropriate controls (e.g., sediment basins or sediment traps, sediment socks, dewatering tanks, tube settlers, weir tanks, or filtration systems). Uncontaminated, non-turbid dewatering water can be discharged without being routed to a control. You must also meet the following requirements for dewatering activities:  Discharge requirements: o No discharging visible floating solids or foam; Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 60 of 129

o Remove oil, grease and other pollutants from dewatering water via an oil-water separator or suitable filtration device (such as a cartridge filter); o Utilize vegetated upland areas of the site, to the extent feasible, to infiltrate dewatering water before discharge. In no case shall waters of the U.S. be considered part of the treatment area; o Implement velocity dissipation devices at all points where dewatering water is discharged; o Haul backwash water away for disposal or return it to the beginning of the treatment process; and o Clean or replace the filter media used in dewatering devices when the pressure differential equals or exceeds the manufacturers’ specifications.  Treatment chemical restrictions: If you use polymers, flocculants or other chemicals to treat dewatering water, you must comply with the requirements in E.G.4.1.8. E.G.4.2.10 Pollution prevention requirements.  Prohibited discharges: o Wastewater from washout of concrete; o Wastewater from washout and cleanout of stucco, paint, form release oils, curing compounds, and other materials; o Fuels, oils, or other pollutants used for operation and maintenance of vehicles or equipment; o Soaps, solvents, or detergents used in vehicle or equipment washing; o Toxic or hazardous substances from a spill or other release. o Design and location requirements: Minimize the discharge of pollutants from pollutant sources by:  Minimizing exposure; o Using secondary containment, spill kits, or other equivalent measures; o Locating pollution sources away from surface waters, storm sewer inlets, and drainageways; o Cleaning up spills immediately (do not clean by hosing area down).  Pollution prevention requirements for wash waters: Minimize the discharge of pollutants from equipment and vehicle washing, wheel wash water, and other wash waters. Wash waters must be treated in a sediment basin or alternative control that provides equivalent or better treatment prior to discharge;  Pollution prevention requirements for the storage, handling, and disposal of construction products, materials, and wastes: Minimize the exposure of building materials, building products, construction wastes, trash, landscape materials, fertilizers, pesticides, herbicides, detergents, sanitary waste, and other materials present on the site to stormwater. Minimization of exposure is not required in cases where the exposure to stormwater will not result in a discharge of pollutants, or where exposure of a specific material or product poses little risk of stormwater contamination (such as final products and materials intended for outdoor use). E.G.4.2.11 Site Stabilization requirements for the construction of staging areas for structures and access roads as defined in E.G.3.2(b) (i.e., not applicable to earth-disturbing activities performed for purposes of mine site preparation as defined in E.G.3.2(a)). You must comply with the following stabilization requirements, except where the intended function of the site accounts for such disturbed earth (e.g., the area of Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 61 of 129

construction will become actively mined, or the controls implemented at the active mining area effectively control the disturbance):  By no later than the end of the next work day after construction work in an area has stopped permanently or temporarily (“temporarily” means the land will be idle for a period of 14 days or more but earth-disturbing activities will resume in the future), immediately initiate stabilization measures;  If using vegetative measures, by no later than 14 days after initiating stabilization: o Seed or plant the area, and provide temporary cover to protect the planted area; o Once established, vegetation must be uniform (evenly distributed without large bare areas) perennial vegetation, which provides 70 percent or more coverage based on density of native vegetation.  If using non-vegetative stabilization, by no later than 14 days after initiating stabilization: o Install or apply all non-vegetative measures; o Cover all areas of exposed soil. Note: For the purposes of this permit, DEQ will consider any of the following types of activities to constitute the initiation of stabilization: 1. Prepping the soil for vegetative or non-vegetative stabilization; 2. Applying mulch or other non- vegetative product to the exposed area; 3. Seeding or planting the exposed area; 4. Starting any of the activities in #1 – 3 on a portion of the area to be stabilized, but not on the entire area; and 5. Finalizing arrangements to have stabilization product fully installed in compliance with the applicable deadline for completing stabilization. Exceptions:  Arid, semi-arid or drought-stricken areas: o Within 14 days of stopping construction work in an area, install any necessary non-vegetative stabilization measures; o Initiate vegetative stabilization as soon as conditions on the site allow; o Document the schedule that will be followed for initiating and completing vegetative stabilization; o Cover planted or seeded area with bio or photo degradable erosion controls designed to prevent erosion without active maintenance.  Sites affected by severe storm events or other unforeseen circumstances: o Initiate vegetative stabilization as soon conditions on the site allow; o Document the schedule that will be followed for initiating and completing vegetative stabilization; o Add a suitable interim measures (such as mulch or bark) are in place if 70 percent coverage of vegetation is expected to expand. E.G.4.3 Water Quality-Based Requirements Applicable to Earth-Disturbing Activities Conducted Prior to Active Mining Activities. The following water quality-based limits apply to earth-disturbing activities conducted prior to active mining activities defined in E.G.3.2(a) and E.G.3.2(b), in addition to the water quality-based limits in Schedule A.4 and Schedule A.5. Stricter requirements apply if your site will discharge to an impaired waters that are listed for turbidity or sedimentation or have an EPA-approved TMDL for sedimentation or turbidity:  More rapid stabilization of exposed areas: Complete initial stabilization activities within 7 days of stopping earth-disturbing work. Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 62 of 129

 More frequent site inspections: Once every 7 days and within 24 hours of a storm event of 0.25 inches or greater. E.G.4.4 Inspection Requirements Applicable to Earth-Disturbing Activities Conducted Prior to Active Mining Activities. The following requirements supersede the inspection requirements in Schedule B and E.G.7 for earth-disturbing activities conducted prior to active mining activities defined in E.G.3.2(a) and E.G.3.2(b). E.G.4.4.1 Inspection frequency  At least once every 7 calendar days, or  Once every 14 calendar days and within 24 hours of a storm event of 0.25 inches or greater. Note: o Inspections only required during working hours; o Inspections not required during unsafe conditions; and o If you choose to inspect once every 14 days, you must have a method for measuring rainfall amount on site (either rain gauge or representative weather station) Note: To determine if a storm event of 0.25 inches or greater has occurred on your site, you must either keep a properly maintained rain gauge on your site, or obtain the storm event information from a weather station that is representative of your location. For any day of rainfall during normal business hours that measures 0.25 inches or greater, you must record the total rainfall measured for that day. Note: You are required to specify in your SWPCP which schedule you will be following. Note: “Within 24 hours of the occurrence of a storm event” means that you are required to conduct an inspection within 24 hours once a storm event has produced 0.25 inches, even if the storm event is still continuing. Thus, if you have elected to inspect bi-weekly and there is a storm event at your site that continues for multiple days, and each day of the storm produces 0.25 inches or more of rain, you are required to conduct an inspection within 24 hours of the first day of the storm and within 24 hours after the end of the storm. E.G.4.4.2 Reductions in inspection frequency.  Stabilized areas: You may reduce the frequency of inspections to once per month in any area of your site where stabilization has occurred pursuant to E.G.4.1.9 or E.G.4.2.11.  Arid, semi-arid, and drought stricken areas: If earth-disturbing activities are occurring during the seasonally dry period or during a period in which drought is predicted to occur, you may reduce inspections to once per month and within 24 hours of a 0.25 inch storm event.  Frozen conditions: You may temporarily suspend or reduce inspections to once per month until thawing conditions occur if frozen conditions are continuous and disturbed areas have been stabilized. For extreme conditions in remote areas, e.g., where transit to the site is perilous/restricted or temperatures are routinely below freezing, you may suspend inspections until the conditions are conducive to safe access, and more frequent inspections can resume. E.G.4.4.3 Areas to be inspected. You must at a minimum inspect the all of the following areas:  Disturbed areas;  Stormwater controls and pollution prevention measures; Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 63 of 129

 Locations where stabilization measures have been implemented;  Material, waste, borrow, or equipment storage and maintenance areas;  Areas where stormwater flows;  Points of discharge. E.G.4.4.4 What to check for during inspections. At a minimum you must check:  Whether all stormwater controls are installed, operational and working as intended;  Whether any new or modified stormwater controls are needed;  For conditions that could lead to a spill or leak;  For visual signs of erosion/sedimentation at points of discharge.  If a discharge is occurring, check:  The quality and characteristics of the discharge;  Whether controls are operating effectively. E.G.4.4.5 Inspection report. Within 24 hours of an inspection, complete a report that includes:  Inspection date;  Name and title of inspector(s);  Summary of inspection findings;  Rainfall amount that triggered the inspection (if applicable);  If it was unsafe to inspect a portion of the site, include documentation of the reason and the location(s);  Each inspection report must be signed;  Keep a current copy of all reports at the site or at an easily accessible location.

E.G.5 Technology-Based Effluent Limits for Active Mining Activities Note: These requirements do not apply for any discharges from earth-disturbing activities conducted prior to active mining as defined in E.G.3.2(a) or E.G.3.2(b). E.G.5.1 Employee training. (See also Schedule A.1.j) Conduct employee training at least annually at active and temporarily inactive facilities. E.G.5.2 Stormwater controls. Apart from the control measures you implement to meet Schedule A technology-based effluent limits, where necessary to minimize pollutant discharges in stormwater, implement the following control measures at your site. The potential pollutants identified in E.G.6.3 shall determine the priority and appropriateness of the control measures selected. For mines subject to dust control requirements under DEQ or county air quality permits, provided the requirements are equivalent, compliance with such air permit dust requirements shall constitute compliance with the dust control effluent limit in Schedule A.1.f. Stormwater diversions: Divert stormwater away from potential pollutant sources through implementation of control measures such as the following, where determined to be feasible including: interceptor or diversion controls (e.g., dikes, swales, curbs, berms); pipe slope drains; subsurface drains; conveyance systems (e.g., channels or gutters, open-top box culverts, and waterbars; rolling dips and road sloping; roadway surface water deflector and culverts); or their equivalents. Capping: When capping is necessary to minimize pollutant discharges in stormwater, identify the source being capped and the material used to construct the cap. Treatment: If treatment of stormwater (e.g., chemical or physical systems, oil - water separators, artificial wetlands) is necessary to protect water quality, describe the type and location of treatment used. Passive and/or active treatment of stormwater runoff is encouraged, where feasible. Treated runoff may be discharged as a stormwater source regulated under this permit Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 64 of 129

provided the discharge is not combined with discharges subject to effluent limitation guidelines for the Ore Mining and Dressing Point Source Category (40 CFR Part 440). E.G.5.3 Discharge testing. Test or evaluate all off-site discharge points covered under this permit for the presence of specific mining-related but unauthorized non-stormwater discharges such as seeps or adit discharges, or discharges subject to effluent limitations guidelines (40 CFR Part 440), mine drainage or process water. Alternatively (if applicable), you may keep a certification with your SWPCP consistent with E.G.6.6.

E.G.6 Additional SWPCP Requirements for Mining Operations Note: The requirements in E.G.6 are not applicable to inactive metal mining facilities. Some requirements may be already a requirement under Schedule A.7. E.G.6.1 Nature of industrial activities. Briefly document in your SWPCP the mining and associated activities that can potentially affect the stormwater discharges covered by this permit, including a general description of the location of the site relative to major transportation routes and communities. E.G.6.2 Site map. Document in your SWPCP the locations of the following (as appropriate): mining or milling site boundaries; access and haul roads; outline of the drainage areas of each stormwater outfall within the facility with indications of the types of discharges from the drainage areas; location(s) of all permitted discharges covered under an individual NPDES permit; outdoor equipment storage, fueling, and maintenance areas; materials handling areas; outdoor manufacturing, outdoor storage, and material disposal areas; outdoor chemicals and explosives storage areas; overburden, materials, soils, or waste storage areas; location of mine drainage (where water leaves mine) or other process water; tailings piles and ponds (including proposed ones); heap leach pads; off-site points of discharge for mine drainage and process water; surface waters; boundary of tributary areas that are subject to effluent limitations guidelines; and location(s) of reclaimed areas. E.G.6.3 Potential pollutant sources. For each area of the mine or mill site where stormwater discharges associated with industrial activities occur, identify the types of pollutants (e.g., heavy metals, sediment) likely to be present in significant amounts. Consider these factors: the mineralogy of the ore and waste rock (e.g., acid forming); toxicity and quantity of chemicals used, produced, or discharged; the likelihood of contact with stormwater; vegetation of site (if any); and history of significant leaks or spills of toxic or hazardous pollutants. Also include a summary of any existing ore or waste rock or overburden characterization data and test results for potential generation of acid rock. If any new data is acquired due to changes in ore type being mined, update your SWPCP with this information. E.G.6.4 Documentation of control measures. Document all control measures that you implement consistent with E.G.5.2. If control measures are implemented or planned but are not listed in E.G.5.2 (e.g., substituting a less toxic chemical for a more toxic one), include descriptions of them in your SWPCP. If you are in compliance with dust control requirements under state or county air quality permits, you must include (or summarize, as necessary) what the state or county air quality permit dust control requirements are and how you’ve achieved compliance with them. E.G.6.5 Employee training. All employee training(s) must be documented in the SWPCP. E.G.6.6 Certification of permit coverage for commingled non-stormwater discharges. If you are able, consistent with E.G.5.3 above, to certify that a particular discharge composed of commingled stormwater and non-stormwater is covered under a separate NPDES permit, and that permit subjects the non-stormwater portion to effluent limitations prior to any commingling, retain such certification with your SWPCP. This certification must identify the non-stormwater Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 65 of 129

discharges, the applicable NPDES permit(s), the effluent limitations placed on the non- stormwater discharge by the permit(s), and the points at which the limitations are applied.

E.G.7 Additional Inspection Requirements Except for earth-disturbing activities conducted prior to active mining activities as defined in E.G.3.2(a) and E.G.3.2(b), which are subject to E.G.4.4, inspect sites at least monthly unless adverse weather conditions make the site inaccessible. See E.G.8.4 for inspection requirements for inactive and unstaffed sites.

E.G.8 Monitoring and Reporting Requirements. (See also Schedule B) Note: There are no monitoring and reporting or impaired waters monitoring requirements for inactive and unstaffed sites. E.G.8.1 Benchmark Monitoring for Active Copper Ore Mining and Dressing Facilities. Table E.G-1 identifies benchmarks that apply to active copper ore mining and dressing facilities. These benchmarks apply to both your primary industrial activity and any co-located industrial activities. Table E.G-1

Subsector Benchmark Monitoring (You may be subject to requirements for more Parameter Concentration than one sector/subsector) Active Copper Ore Mining and Dressing Facilities Nitrate plus Nitrite Nitrogen 0.68 mg/L (SIC 1021) Chemical Oxygen Demand 120 mg/L (COD) E.G.8.2 Benchmark Monitoring Requirements for Discharges From Waste Rock and Overburden Piles at Active Metal Mining Facilities. For discharges from waste rock and overburden piles, perform benchmark monitoring once in the first year for the parameters listed in Table E.G-2, and twice annually in all subsequent years of coverage under this permit for any parameters for which the benchmark has been exceeded. You are also required to conduct analytic monitoring for the parameters listed in Table E.G-3 in accordance with the requirements in E.G.8.3. DEQ may also notify you that you must perform additional monitoring to accurately characterize the quality and quantity of pollutants discharged from your waste rock and overburden piles. Table E.G-2 Subsector Benchmark Monitoring (You may be subject to requirements for more Parameter Concentration than one sector/subsector) Iron Ores; Copper Ores; Lead and Zinc Ores; Gold Turbidity 50 NTU and Silver Ores; Ferroalloy Ores, Except Vanadium; pH 6.0-9.0 s.u. and Miscellaneous Metal Ores (SIC Codes 1011, Total Antimony 0.64 mg/L 1021, 1031, 1041, 1044, 1061, 1081, 1094, 1099) Total Arsenic 0.15 mg/L Total Beryllium 0.13 mg/L Total Iron 1.0 mg/L Total Mercury 0.0014 mg/L Total Nickel 0.5 mg/L Total Selenium 0.005 mg/L Total Silver 0.0005 mg/L Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 66 of 129

E.G.8.3 Additional Analytic Monitoring Requirements for Discharges From Waste Rock and Overburden Piles at Active Metal Mining Facilities. In addition to the monitoring required in E.G.8.2 for discharges from waste rock and overburden piles, you must also conduct monitoring for additional parameters based on the type of ore you mine at your site. Where a parameter in Table E.G-3 is the same as a pollutant you are required to monitor for in Table E.G-2 (i.e., for all of the metals), you must use the corresponding benchmark in Table E.G-2 and you may use any monitoring results conducted for E.G.8.2 to satisfy the monitoring requirement for that parameter for E.G.8.3. For radium and uranium, which do not have corresponding benchmarks in Table E.G-2, there are no applicable benchmarks. The frequency and schedule for monitoring for these additional parameters is the same as that specified in Table 5. Table E.G-3. Additional Monitoring Requirements for Discharges from Waste Rock and Overburden Piles Supplemental Requirements Pollutants of Concern Type of Ore Mined Total Suspended pH Metals, Total Solids (TSS) Tungsten Ore X X Arsenic, Cadmium (H), Copper (H), Lead (H), Zinc (H) Nickel Ore X X Arsenic, Cadmium (H), Copper (H), Lead (H), Zinc (H) Aluminum Ore X X Iron Mercury Ore X X Nickel (H) Iron Ore X X Iron (Dissolved) Platinum Ore Cadmium (H), Copper (H), Mercury, Lead (H), Zinc (H) Titanium Ore X X Iron, Nickel (H), Zinc (H) Vanadium Ore X X Arsenic, Cadmium (H), Copper (H), Lead (H), Zinc (H) Molybdenum X X Arsenic, Cadmium (H), Copper (H), Lead (H), Mercury, Zinc (H) Uranium, Radium, and X X Chemical Oxygen Demand, Arsenic, Vanadium Ore Radium (Dissolved and Total), Uranium, Zinc (H) Note: An “X” indicated for TSS and/or pH means that you are required to monitor for those parameters. (H) indicates that hardness must also be measured when this pollutant is measured.

E.G.8.4 Inactive and Unstaffed Sites – Conditional Exemption from No Exposure Requirements for Monthly Visual Assessments and Routine Facility Inspections. As a Sector G facility, if you are seeking to exercise a monitoring or inspection waiver, you are conditionally exempt from the requirement to certify that “there are no industrial materials or activities exposed to stormwater” in Schedule B.4.iii of the permit. This exemption is conditioned on the following:  If circumstances change and your facility becomes active and/or staffed, this exception no longer applies and you must immediately begin complying with the monitoring and inspection requirements; and  DEQ retains the authority to revoke this exemption and/or the monitoring waiver where it is determined that the discharge causes, has a reasonable potential to cause, or contributes to an instream excursion above an applicable water quality standard, including designated uses.

Non-stormwater discharges from these sources are subject to NPDES permitting and may be subject to the effluent limitation guidelines under 40 CFR Part 440. Discharges from overburden/waste rock and overburden/waste rock- related areas are not subject to 40 CFR Part 440 unless: (1) it drains naturally (or is intentionally diverted) to a point source; and (2) combines with ''mine drainage'' that is otherwise regulated under the Part 440 regulations. For such sources, coverage under this permit would be available if the discharge composed entirely of stormwater does not combine with other sources of mine drainage that are not subject to 40 CFR Part 440, as well as meeting other eligibility criteria contained in Part 1.1 of the permit. Operators bear the initial responsibility for determining the applicable technology-based standard for such discharges.

E.G.9. Termination of Permit Coverage E.G.9.1 Termination of Permit Coverage for Sites Reclaimed After December 17, 1990. A site or a portion of a site that has been released from applicable state or federal reclamation requirements after December 17, 1990, is no longer required to maintain coverage under this permit. If the site or portion of a site reclaimed after December 17, 1990, was not subject to reclamation requirements, the site or portion of the site is no longer required to maintain coverage under this permit if the site or portion of the site has been reclaimed as defined in E.G.3.3. E.G.9.2 Termination of Permit Coverage for Sites Reclaimed Before December 17, 1990. A site or portion of a site that was released from applicable state or federal reclamation requirements before December 17, 1990, or that was otherwise reclaimed before December 17, 1990, is no longer required to maintain coverage under this permit if the site or portion of the site has been reclaimed. A site or portion of a site is considered to have been reclaimed if: (1) stormwater runoff that comes into contact with raw materials, intermediate byproducts, finished products, and waste products does not have the potential to cause or contribute to violations of state water quality standards, (2) soil disturbing activities related to mining at the sites or portion of the site have been completed, (3) the site or portion of the site has been stabilized to minimize soil erosion, and (4) as appropriate depending on location, size, and the potential to contribute pollutants to stormwater discharges, the site or portion of the site has been revegetated, will be amenable to natural revegetation, or will be left in a condition consistent with the post-mining land use.

Schedule E – Sector-Specific Requirements for Industrial Activity Sector H – Coal Mines and Coal Mining-Related Facilities

E.H.1 Definitions The following definitions are not intended to supersede the definitions of active and inactive mining facilities established by 40 CFR 122.26(b)(14)(iii). E.H.1.1 Mining operations - For this permit, mining operations are grouped into two distinct categories, with distinct effluent limits and requirements applicable to each: a) earth-disturbing activities conducted prior to active mining activities); and b) active mining activities, which includes reclamation. “Mining operations” can occur at both inactive mining facilities and temporarily inactive mining facilities. E.H.1.2 Earth-disturbing activities conducted prior to active mining activities – Consists of two classes of earth-disturbing (i.e., clearing, grading and excavation) activities: a. activities performed for purposes of mine site preparation, including: cutting new rights of way (except when related to access road construction); providing access to a mine site for vehicles and equipment (except when related to access road construction); other earth disturbances associated with site preparation activities on any areas where active mining activities have not yet commenced (e.g., for heap leach pads, waste rock facilities, tailings impoundments, wastewater treatment plants); and b. construction of staging areas to prepare for erecting structures such as to house project personnel and equipment, mill buildings, etc., and construction of access roads. Earth-disturbing activities associated with the construction of staging areas and the construction of access roads conducted prior to active mining are considered to be “construction” and have additional technology based effluent limits in E.H.2.2. E.H.1.3 Active mining activities – Activities related to the extraction, removal or recovery, and preparation of coal; removal of overburden and waste rock to expose mineable minerals; and site reclamation and closure activities. All such activities occur within the “active mining area.” Reclamation involves activities undertaken, in compliance with applicable mined land reclamation requirements, to return the land to an appropriate post-mining contour and land use in order to meet applicable federal and state reclamation requirements. In addition, once earth- disturbing activities conducted prior to active mining activities have ceased and all related requirements in E.H.2 have been met, and a well-delineated “active mining area” has been established, all activities (including any clearing, grading, and excavation) that occur within the active mining area are “active mining activities.” E.H.1.4 Active mining area – A place where work or other activity related to the extraction, removal or recovery of coal is being conducted, except, with respect to surface mines, any area of land on or in which grading has been completed to return the earth to desired contour and reclamation work has begun. Note: Earth-disturbing activities described in the definition in E.H.1.2 that occur on areas outside the active mining area (e.g., for expansion of the mine into undeveloped territory) are considered “earth-disturbing conducted prior to active mining activities”, and must comply with the requirements in E.H.2. E.H.1.5 Inactive coal mining facility – A site or portion of a site where coal mining and/or milling occurred in the past but there are no active mining operations occurring as defined above, and where the inactive portion is not covered by an active mining permit issued by the applicable state or federal agency. An inactive coal mining facility has an identifiable owner / operator. Sites where mining claims are being maintained prior to disturbances associated with the Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 70 of 129

extraction, beneficiation, or processing of mined materials and sites where minimal activities are undertaken for the sole purpose of maintaining a mining claim are not considered either active or inactive mining facilities and do not require an NPDES industrial stormwater permit. E.H.1.6 Temporarily inactive coal mining facility – A site or portion of a site where coal mining and/or milling occurred in the past but currently are not being actively undertaken, and the facility is covered by an active mining permit issued by the applicable state or federal agency.

E.H.2 Requirements Applicable to Earth-Disturbing Activities Conducted Prior to Active Mining Activities Stormwater discharges from earth-disturbing activities conducted prior to active mining activities (defined in E.H.1.2) are covered under this permit. For such earth-disturbing activities, you must comply with all applicable requirements in technology-based effluent limits in E.H.3 and Schedule A, the inspection and monitoring requirements in Schedule B and in E.H.5 and E.H.6 Authorized discharges from areas where earth-disturbing activities have ceased and stabilization as specified in E.H.2.1.9 or E.H.2.2.11, where appropriate, has been completed (stabilization is not required for areas where active mining activities will occur), are no longer subject to the E.H.2 requirements. At such time, authorized discharges become subject to all other applicable requirements in the permit, including the technology based effluent limits in limits in E.H.3 and Schedule A, the inspection and monitoring requirements in Schedule B and in E.H.5 and E.H.6.

E.H.2.1 Technology-Based Effluent Limits Applicable to All Earth-Disturbing Activities Conducted Prior to Active Mining Activities. The following technology-based effluent limits apply to authorized discharges from all earth-disturbing activities conducted prior to active mining activities defined in E.H.1.2(a) and E.H.1.2(b). These limits supersede the technology-based effluent limits listed in Schedule A. E.H.2.1.1 Erosion and sediment control installation requirements.  By the time construction activities commence, install and make operational downgradient sediment controls, unless this timeframe is infeasible. If infeasible you must install and make such controls operational as soon as practicable or as soon as site conditions permit.  All other stormwater controls described in the SWPCP must be installed and made operational as soon as conditions on each portion of the site allows. E.H.2.1.2 Erosion and sediment control maintenance requirements. You must:  Ensure that all erosion and sediment controls remain in effective operating condition.  Wherever you determine that a stormwater control needs maintenance to continue operating effectively, initiate efforts to fix the problem immediately after its discovery, and complete such work by the end of the next work day.  When a stormwater control must be replaced or significantly repaired, complete the work within 7 days, unless infeasible. If 7 days is infeasible, you must complete the installation or repair as soon practicable. E.H.2.1.3 Perimeter controls. You must:  Install sediment controls along those perimeter areas of your disturbed area that will receive stormwater, except where site conditions prevent the use of such controls (in which case, maximize their installation to the extent practicable).  Remove sediment before it accumulates to one-half of the above-ground height of any perimeter control. Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 71 of 129

E.H.2.1.4 Sediment track-out. For construction vehicles and equipment exiting the site directly onto paved roads, you must:  Use appropriate stabilization techniques to minimize sediment track-out from vehicles and equipment prior to exit;  Use additional controls to remove sediment from vehicle and equipment tires prior to exit, where necessary;  Remove sediment that is tracked out onto paved roads by end of the work day. Note: DEQ recognizes that some fine grains may remain visible on the surfaces of off- site streets, other paved areas, and sidewalks even after you have implemented sediment removal practices. Such “staining” is not a violation of E.H.2.1.4. E.H.2.1.5 Soil or sediment stockpiles. You must:  Minimize erosion of stockpiles from stormwater and wind via temporary cover, if feasible.  Prevent up-slope stormwater flows from causing erosion of stockpiles (e.g., by diverting flows around the stockpile).  Minimize sediment from stormwater that runs off of stockpiles, using sediment controls (e.g., a sediment barrier or downslope sediment control). E.H.2.1.6 Sediment basins. If you intend to install a sediment basin to treat stormwater from your earth-disturbing activities, you must:  Provide storage for either (1) the 2-year, 24-hour storm, or (2) 3,600 cubic feet per acre drained.  Prevent erosion of (1) basin embankments using stabilization controls (e.g., erosion control blankets), and (2) the inlet and outlet points of the basin using erosion controls and velocity dissipation devices. E.H.2.1.7 Minimize dust. You must minimize the generation of dust through the appropriate application of water or other dust suppression techniques that minimize pollutants being discharged into surface waters. E.H.2.1.8 Restrictions on use of treatment chemicals. If you intend to use sediment treatment chemicals at your site, you are subject to the following minimum requirements:  Use conventional erosion and sediment controls prior to and after application of chemicals;  Select chemicals suited to soil type, and expected turbidity, pH, flow rate;  Minimize the discharge risk from stored chemicals;  Comply with state/local requirements;  Use chemicals in accordance with good engineering practices and specifications of chemical supplier;  Ensure proper training;  Provide proper SWPCP documentation. If you plan to use cationic treatment chemicals (as defined in Appendix A), you are ineligible for coverage under this permit, unless you notify your applicable DEQ regional office or agent in advance and the DEQ regional office or agent authorizes coverage under this permit after you have included appropriate controls and implementation procedures designed to ensure that your use of cationic treatment chemicals will not lead to a violation of water quality standards. E.H.2.1.9 Site stabilization requirements for earth-disturbing activities performed for purposes of mine site preparation as defined in E.H.1.2(a) (i.e., not applicable to construction Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 72 of 129

of staging areas for structures and access roads as defined in E.H.1.2(b)). You must comply with the following stabilization requirements except where the intended function of the site accounts for such disturbed earth (e.g., the earth disturbances will become actively mined, or the controls implemented at the active mining area effectively control the disturbance):  Temporary stabilization of disturbed areas. Stabilization measures must be initiated immediately in portions of the site where earth-disturbing activities performed for purposes of mine site preparation (as defined in E.H.1.2(a)) have temporarily ceased, but in no case more than 14 days after such activities have temporarily ceased. In arid, semi-arid, and drought-stricken areas, or in areas subject to snow or freezing conditions, where initiating perennial vegetative stabilization measures is not possible within 14 days after earth-disturbing activities performed for purposes of mine site preparation has temporarily ceased, temporary vegetative stabilization measures must be initiated as soon as practicable. Until temporary vegetative stabilization is achieved, interim measures such as erosion control blankets with an appropriate seed base and tackifiers must be employed. In areas of the site where earth-disturbing activities performed for purposes of mine site preparation have permanently ceased prior to active mining, temporary stabilization measures must be implemented to minimize mobilization of sediment or other pollutants until active mining activities commence.

 Final stabilization of disturbed areas. Stabilization measures must be initiated immediately where earth-disturbing activities performed for purposes of mine site preparation (as defined in E.H.1.2(a)) have permanently ceased, but in no case more than 14 days after the earth-disturbing activities have permanently ceased. In arid, semi-arid, and drought-stricken areas, or in areas subject to snow or freezing conditions, where initiating perennial vegetative stabilization measures is not possible within 14 days after earth-disturbing activities have permanently ceased, final vegetative stabilization measures must be initiated as soon as possible. Until final stabilization is achieved, temporary stabilization measures, such as erosion control blankets with an appropriate seed base and tackifiers, must be used.

E.H.2.2 Additional Technology-Based Effluent Limits Applicable Only to the Construction of Staging Areas for Structures and Access Roads. The following technology-based effluent limits apply to authorized discharges from earth-disturbing activities associated with the construction of staging areas and the construction of access roads, as defined in E.H.1.2(b). These limits supersede the technology-based limits listed in Schedule A and E.H.3. These limits do not apply to earth-disturbing activities performed for purposes of mine site preparation (as defined in E.H.1.2(a)). E.H.2.2.1 Area of disturbance. You must minimize the amount of soil exposed during construction activities. E.H.2.2.2 Erosion and sediment control design requirements. You must:  Design, install and maintain effective erosion and sediment controls to minimize the discharge of pollutants from construction activities. Account for the following factors in designing your erosion and sediment controls: o The expected amount, frequency, intensity and duration of precipitation; Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 73 of 129

o The nature of stormwater runoff and run-on at the site, including factors such as impervious surfaces, slopes and site drainage features; o The range of soil particle sizes expected to be present on the site.  Direct discharges from your stormwater controls to vegetated areas of your site to increase sediment removal and maximize stormwater infiltration, including any natural buffers, unless infeasible. Use velocity dissipation devices if necessary to prevent erosion when directing stormwater to vegetated areas.  If any stormwater flow becomes or will be channelized at your site, you must design erosion and sediment controls to control both peak flowrates and total stormwater volume to minimize channel and streambank erosion and scour in the immediate vicinity of discharge points.  If you install stormwater conveyance channels, they must be designed to avoid unstabilized areas on the site and to reduce erosion, unless infeasible. In addition, you must minimize erosion of channels and their embankments, outlets, adjacent streambanks, slopes, and downstream waters during discharge conditions through the use of erosion controls and velocity dissipation devices within and along the length of any constructed stormwater conveyance channel, and at any outlet to provide a non-erosive flow velocity. E.H.2.2.3 Natural Buffers. For any stormwater discharges from earth-disturbing activities within 50 feet of a water of the U.S., you must comply with one of the following compliance alternatives: 1. Maintain a 50-foot undisturbed natural buffer between earth-disturbing activities and the water of the U.S.; or 2. Provide an undisturbed natural buffer that is less than 50 feet, permit registrant must implement one or more of the BMPs listed below to control and treat sediment and turbidity:  Compost berms, compost blankets, or compost socks;  Erosion control mats;  Takifiers used in combination with perimeter sediment controls;  Approved water treatment by electro-coagulation, flocculation, or filtration; and/or  Other substantially equivalent sediment or turbidity control measures approved by DEQ or agent. 3. Ensure all discharges are treated by control measures prior to entering the natural buffer. 4. Delineate and clearly mark off all natural buffers. There are exceptions when buffer requirements do not apply:  The natural buffer has already been eliminated by preexisting development disturbances;  The disturbance is for a water-dependent structure or earth-disturbing approved under a CWA section 404 permit. E.H.2.2.4 Soil or sediment stockpiles. In addition to the requirements in E.H.2.1.5, you must locate any piles outside of any natural buffers established under E.H.2.2.3. E.H.2.2.5 Sediment basins. In addition to the requirements in E.H.2.1.6, you must locate sediment basins outside of any surface waters and any natural buffers established Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 74 of 129

under E.H.2.2.3, and you must utilize outlet structures that withdraw water from the surface, unless infeasible. E.H.2.2.6 Native topsoil preservation. You must preserve native topsoil removed during clearing, grading, or excavation, unless infeasible. Store topsoil in a manner that will maximize its use in reclamation or final vegetative stabilization (e.g., by keeping the topsoil stabilized with seed or similar measures). This requirement does not apply if the intended function of the disturbed area dictates that topsoil be disturbed or removed. E.H.2.2.7 Steep slopes. You must minimize the disturbance of steep slopes. The permit does not prevent or prohibit disturbance on steep slopes. Depending on site conditions and needs, disturbance on steep slopes may be necessary (e.g., a road cut in mountainous terrain; for grading steep slopes prior to erecting the mine office). Where steep slope disturbances are necessary, you can minimize the disturbances to steep slopes through the implementation of a number of standard erosion and sediment control practices, such as by phasing disturbances in these areas and using stabilization practices specifically for steep grades. E.H.2.2.8 Soil compaction. Where final vegetative stabilization will occur or where infiltration practices will be installed, you must either restrict vehicle/ equipment use in these areas to avoid soil compaction or use soil conditioning techniques to support vegetative growth. Minimizing soil compaction is not required where compacted soil is integral to the functionality of the site. E.H.2.2.9 Dewatering Practices. You are prohibited from discharging ground water or accumulated stormwater that is removed from excavations, trenches, foundations, vaults or other similar points of accumulation, unless such waters are first effectively managed by appropriate controls (e.g., sediment basins or sediment traps, sediment socks, dewatering tanks, tube settlers, weir tanks, or filtration systems). Uncontaminated, non-turbid dewatering water can be discharged without being routed to a control. You must also meet the following requirements for dewatering activities:  Discharge requirements: o No discharging visible floating solids or foam; o Remove oil, grease and other pollutants from dewatering water via an oil-water separator or suitable filtration device (such as a cartridge filter); o Utilize vegetated upland areas of the site, to the extent feasible, to infiltrate dewatering water before discharge. In no case shall waters of the U.S. be considered part of the treatment area; o Implement velocity dissipation devices at all points where dewatering water is discharged; o Haul backwash water away for disposal or return it to the beginning of the treatment process; and o Clean or replace the filter media used in dewatering devices when the pressure differential equals or exceeds the manufacturers’ specifications.  Treatment chemical restrictions: If you use polymers, flocculants or other chemicals to treat dewatering water, you must comply with the requirements in E.H.2.1.8.

Wash waters must be treated in a sediment basin or alternative control that provides equivalent or better treatment prior to discharge;  Pollution prevention requirements for the storage, handling, and disposal of construction products, materials, and wastes: Minimize the exposure of building materials, building products, construction wastes, trash, landscape materials, fertilizers, pesticides, herbicides, detergents, sanitary waste, and other materials present on the site to stormwater. Minimization of exposure is not required in cases where the exposure to stormwater will not result in a discharge of pollutants, or where exposure of a specific material or product poses little risk of stormwater contamination (such as final products and materials intended for outdoor use). E.H.2.2.11 Site Stabilization requirements for the construction of staging areas for structures and access roads as defined in E.H.1.2(b) (i.e., not applicable to earth-disturbing activities performed for purposes of mine site preparation as defined in E.H.1.2(a)). You must comply with the following stabilization requirements, except where the intended function of the site accounts for such disturbed earth (e.g., the area of construction will become actively mined, or the controls implemented at the active mining area effectively control the disturbance):  By no later than the end of the next work day after construction work in an area has stopped permanently or temporarily (“temporarily” means the land will be idle for a period of 14 days or more but earth-disturbing activities will resume in the future), immediately initiate stabilization measures;  If using vegetative measures, by no later than 14 days after initiating stabilization: o Seed or plant the area, and provide temporary cover to protect the planted area; o Once established, vegetation must be uniform (evenly distributed without large bare areas) perennial vegetation, which provides 70 percent or more coverage based on density of native vegetation. Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 76 of 129

 If using non-vegetative stabilization, by no later than 14 days after initiating stabilization: o Install or apply all non-vegetative measures; o Cover all areas of exposed soil. Note: For the purposes of this permit, DEQ will consider any of the following types of activities to constitute the initiation of stabilization: 1. Prepping the soil for vegetative or non-vegetative stabilization; 2. Applying mulch or other non-vegetative product to the exposed area; 3. Seeding or planting the exposed area; 4. Starting any of the activities in #1 – 3 on a portion of the area to be stabilized, but not on the entire area; and 5. Finalizing arrangements to have stabilization product fully installed in compliance with the applicable deadline for completing stabilization. Exceptions:  Arid, semi-arid or drought-stricken areas: o Within 14 days of stopping construction work in an area, install any necessary non-vegetative stabilization measures; o Initiate vegetative stabilization as soon as conditions on the site allow; o Document the schedule that will be followed for initiating and completing vegetative stabilization; o Cover planted or seeded area with bio or photo degradable erosion controls designed to prevent erosion without active maintenance.  Sites affected by severe storm events or other unforeseen circumstances: o Initiate vegetative stabilization as soon conditions on the site allow; o Document the schedule that will be followed for initiating and completing vegetative stabilization; o Add a suitable interim measures (such as mulch or bark) are in place if 70 percent coverage of vegetation is expected to expand.

E.H.2.3 Water Quality-Based Requirements Applicable to Earth-Disturbing Activities Conducted Prior to Active Mining Activities. The following water quality-based limits apply to earth-disturbing activities conducted prior to active mining activities defined in E.H.1.2(a) and E.H.1.2(b), in addition to the water quality- based limits Schedule A.4 and A.5. Stricter requirements apply if your site will discharge to an impaired waters that are listed for turbidity or sedimentation or have an EPA-approved TMDL for sedimentation or turbidity:  More rapid stabilization of exposed areas: Complete initial stabilization activities within 7 days of stopping earth-disturbing work.  More frequent site inspections: Once every 7 days and within 24 hours of a storm event of 0.25 inches or greater.

E.H.2.4 Inspection Requirements Applicable to Earth-Disturbing Activities Conducted Prior to Active Mining Activities. The following requirements supersede the inspections requirements in Schedule B and E.H.7 of the permit for earth-disturbing activities conducted prior to active mining activities defined in E.H.1.2(a) and E.H.1.2(b). E.H.2.4.1 Inspection Frequency  At least once every 7 calendar days, or Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 77 of 129

 Once every 14 calendar days and within 24 hours of a storm event of 0.25 inches or greater. Note: o Inspections only required during working hours; o Inspections not required during unsafe conditions; and o If you choose to inspect once every 14 days, you must have a method for measuring rainfall amount on site (either rain gauge or representative weather station) Note: To determine if a storm event of 0.25 inches or greater has occurred on your site, you must either keep a properly maintained rain gauge on your site, or obtain the storm event information from a weather station that is representative of your location. For any day of rainfall during normal business hours that measures 0.25 inches or greater, you must record the total rainfall measured for that. Note: You are required to specify in your SWPCP which schedule you will be following. Note: “Within 24 hours of the occurrence of a storm event” means that you are required to conduct an inspection within 24 hours once a storm event has produced 0.25 inches, even if the storm event is still continuing. Thus, if you have elected to inspect bi-weekly in and there is a storm event at your site that continues for multiple days, and each day of the storm produces 0.25 inches or more of rain, you are required to conduct an inspection within 24 hours of the first day of the storm and within 24 hours after the end of the storm. E.H.2.4.2 Reductions in Inspection Frequency  Stabilized areas: You may reduce the frequency of inspections to once per month in any area of your site where stabilization has occurred pursuant to E.H.2.1.9 or E.H.2.2.11.  Arid, semi-arid, and drought stricken areas: If earth-disturbing activities are occurring during the seasonally dry period or during a period in which drought is predicted to occur, you may reduce inspections to once per month and within 24 hours of a 0.25 inch storm event.  Frozen conditions: You may temporarily suspend or reduce inspections to once per month until thawing conditions occur if frozen conditions are continuous and disturbed areas have been stabilized. For extreme conditions in remote areas, e.g., where transit to the site is perilous/restricted or temperatures are routinely below freezing, you may suspend inspections until the conditions are conducive to safe access, and more frequent inspections can resume. E.H.2.4.3 Areas to be Inspected. You must at a minimum inspect the following areas:  Disturbed areas;  Stormwater controls and pollution prevention measures;  Locations where stabilization measures have been implemented;  Material, waste, borrow, or equipment storage and maintenance areas;  Areas where stormwater flows;  Points of discharge. E.H.2.4.4 What to Check for During Inspections. At a minimum you must check:  Whether all stormwater controls are installed, operational, and working as intended;  Whether any new or modified stormwater controls are needed; Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 78 of 129

 For conditions that could lead to a spill or leak;  For visual signs of erosion/sedimentation at points of discharge. If a discharge is occurring:  The quality and characteristics of the discharge;  Whether controls are operating effectively. E.H.2.4.5 Inspection Report. Within 24 hours of an inspection, complete a report that includes:  Inspection date;  Name and title of inspector(s);  Summary of inspection findings;  Rainfall amount that triggered the inspection (if applicable);  If it was unsafe to inspect a portion of the site, include documentation of the reason and the location(s);  Each inspection report must be signed;  Keep a current copy of all reports at the site or at an easily accessible location.

E.H.2.5 Cessation of Requirements Applicable to Earth-Disturbing Activities Conducted Prior to Active Mining Activities.

Earth-disturbing activities have ceased; and 2. Stabilization has been met consistent with E.H.2.1.9 or E.H.2.2.11 (not required for areas where active mining activities will occur).

E.H.3 Technology-Based Effluent Limits for Active Mining Activities Note: These requirements do not apply for any discharges from earth-disturbing activities conducted prior to active mining as defined in E.H.1.2(a) or E.H.1.2(b). E.H.3.1 Good Housekeeping Measures. As part of your good housekeeping program, in order to minimize discharges of pollutants in stormwater, implement control measures such as the following, where determined to be feasible including: using sweepers and covered storage; watering haul roads to minimize dust generation; and conserving vegetation to minimize erosion. For mines subject to dust control requirements under state or county air quality permits, provided the requirements are equivalent, compliance with such air permit dust requirements shall constitute compliance with the dust control effluent limit in Schedule A.1.f. E.H.3.2 Preventive Maintenance. Perform inspections or other equivalent measures of storage tanks and pressure lines of fuels, lubricants, hydraulic fluid, and slurry to prevent leaks due to deterioration or faulty connections.

E.H.4 Additional SWPCP Requirements for Mining Operations Note: The requirements in E.H.6 are not applicable to inactive coal mining facilities. Some requirements may be already a requirement under Schedule A.7. E.H.4.1 Other Applicable Regulations. Most active coal mining-related areas (SIC Codes 1221-1241) are subject to sediment and erosion control regulations of the U.S. Office of Surface Mining (OSM) that enforces the Surface Mining Control and Reclamation Act (SMCRA). OSM has granted authority to most coal-producing states to implement SMCRA through State SMCRA regulations. All SMCRA requirements regarding control of stormwater-related pollutant discharges must be addressed and then documented with the SWPCP (directly or by reference).

E.H.6.1 Inactive and Unstaffed Sites – Conditional Exemption from No Exposure Requirements for Monthly Visual Assessments and Routine Facility Inspections. As a Sector H facility, if you are seeking to exercise a monitoring or inspection waiver, you are conditionally exempt from the Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 80 of 129

requirement to certify that “there are no industrial materials or activities exposed to stormwater” in Schedule B.4.iii of the permit. This exemption is conditioned on the following:  If circumstances change and your facility becomes active and/or staffed, this exception no longer applies and you must immediately begin complying with the monitoring and inspection requirements; and  DEQ retains the authority to revoke this exemption and/or the monitoring waiver where it is determined that the discharge causes, has a reasonable potential to cause, or contributes to an instream excursion above an applicable water quality standard, including designated uses. Subject to the two conditions above, if your facility is inactive and unstaffed, you are waived from the requirement to conduct routine facility inspections, monthly visual assessments, and benchmark and impaired waters monitoring. You are encouraged to inspect your site more frequently where you have reason to believe that severe weather or natural disasters may have damaged control measures or increased discharges.

E.H.7 Termination of Permit Coverage E.H.7.1 Termination of Permit Coverage for Sites Reclaimed After December 17, 1990. A site or a portion of a site that has been released from applicable state or federal reclamation requirements after December 17, 1990, is no longer required to maintain coverage under this permit. If the site or portion of a site reclaimed after December 17, 1990, was not subject to reclamation requirements, the site or portion of the site is no longer required to maintain coverage under this permit if the site or portion of the site has been reclaimed. E.H.7.2 Termination of Permit Coverage for Sites Reclaimed Before December 17, 1990. A site or portion of a site that was released from applicable state or federal reclamation requirements before December 17, 1990, or that was otherwise reclaimed before December 17, 1990, is no longer required to maintain coverage under this permit if the site or portion of the site has been reclaimed. A site or portion of a site is considered to have been reclaimed if: (1) stormwater runoff that comes into contact with raw materials, intermediate byproducts, finished products, and waste products does not have the potential to cause or contribute to violations of state water quality standards, (2) soil disturbing activities related to mining at the sites or portion of the site have been completed, (3) the site or portion of the site has been stabilized to minimize soil erosion, and (4) as appropriate depending on location, size, and the potential to contribute pollutants to stormwater discharges, the site or portion of the site has been revegetated, will be amenable to natural revegetation, or will be left in a condition consistent with the post-mining land use.

E.S.3.1.7 Management of Runoff. Minimize the discharge of pollutants in stormwater from deicing chemicals in runoff. To minimize discharges of pollutants in stormwater from aircraft deicing, implement runoff management control measures such as the following, where determined to be feasible and that accommodate considerations of safety, space, operational constraints, and flight considerations (list not exclusive): installing a centralized deicing pad to recover deicing fluid following application; plug-and-pump (PnP); using vacuum/collection trucks (glycol recovery vehicles); storing contaminated stormwater/deicing fluids in tanks; recycling collected deicing fluid where feasible; releasing controlled amounts to a publicly owned treatment works; separation of contaminated snow; conveying contaminated runoff into a stormwater impoundment for biochemical decomposition (be aware of attracting wildlife that may prove hazardous to flight operations); and directing runoff into vegetative swales or other infiltration measures. To minimize discharges of pollutants in stormwater from runway deicing, implement runoff management control measures such as the following, where determined to be feasible and that accommodate considerations of safety, space, operational constraints, and flight considerations (list not exclusive): mechanical systems (snow plows, brushes); conveying contaminated runoff into swales and/or a stormwater impoundment; and pollution prevention practices such as ice detection systems, and airfield prewetting. When applying deicing fluids during non-precipitation events (also referred to as “clear ice deicing”), implement control measures to prevent unauthorized discharge of pollutants (dry-weather discharges of pollutants would need coverage under an NPDES wastewater permit), or to minimize the discharge of pollutants from deicing fluids in later stormwater discharges, implement control measures such as the following, where determined to be feasible and that accommodate considerations safety, space, operational constraints, and flight considerations (list not exclusive): recovering deicing fluids; preventing the fluids from entering storm sewers or other stormwater discharge conveyances (e.g., covering storm sewer inlets, using booms, installing absorptive interceptors in the drains); releasing controlled amounts to a publicly owned treatment works Used deicing fluid should be recycled whenever practicable. E.S.3.2 Deicing Season. You must determine the seasonal timeframe (e.g., December- February, October - March, etc.) during which deicing activities typically occur at the facility. Implementation of control measures, including any BMPs, facility inspections and monitoring must be conducted with particular emphasis throughout the defined deicing season. If you meet the deicing chemical usage thresholds of 100,000 gallons glycol and/or 100 tons of urea, the deicing season you identified is the timeframe during which you must obtain the four required benchmark monitoring event results for deicing-related parameters, i.e., BOD, COD, ammonia and pH.

If you use deicing chemicals, you must maintain a record of the types (including the Safety Data Sheets [SDS]) used and the monthly quantities, either as measured or, in the absence of metering, as estimated to the best of your knowledge. This includes all deicing chemicals, not just glycols and urea (e.g., potassium acetate), because large quantities of these other chemicals can still have an adverse impact on receiving waters. Tenants or other fixed-based operations that conduct deicing operations must provide the above information to the airport authority for inclusion with any comprehensive airport SWPCPs. E.S.4.3 Vehicle and Equipment Washwater Requirements. Attach to or reference in your SWPCP, a copy of the NPDES permit issued for vehicle/equipment washwater, if applicable.

A9. Permit Fees The permittee must pay the fees required by OAR.

SECTION B. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS B1. Proper Operation and Maintenance The permittee must at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) that are installed or used by the permittee to achieve

Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 121 of 129

compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires

the operation of back-up or auxiliary facilities or similar systems that are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit.

B2. Need to Halt or Reduce Activity Not a Defense For industrial or commercial facilities, upon reduction, loss, or failure of the treatment facility, the permittee must, to the extent necessary to maintain compliance with its permit, control production or all discharges or both until the facility is restored or an alternative method of treatment is provided. This requirement applies, for example, when the primary source of power of the treatment facility fails or is reduced or lost. It is not a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.

B3. Bypass of Treatment Facilities a. Definitions (1) "Bypass" means intentional diversion of waste streams from any portion of the treatment facility. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, provided the diversion is to allow essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of paragraphs b and c of this section. (2) "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. b. Prohibition of bypass. (1) Bypass is prohibited and DEQ may take enforcement action against a permittee for bypass unless: i. Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; ii. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventative maintenance; and iii. The permittee submitted notices and requests as required under General Condition B3.c. (2) DEQ may approve an anticipated bypass, after considering its adverse effects and any alternatives to bypassing, if DEQ determines that it will meet the three conditions listed above in General Condition B3.b.(1). c. Notice and request for bypass. (1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, a written notice must be submitted to DEQ at least ten days before the date of the bypass.

Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 122 of 129

(2) Unanticipated bypass. The permittee must submit notice of an unanticipated bypass as required in General Condition D5.

B4. Upset a. Definition. "Upset" means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operation error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. b. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology-based permit effluent limitations if the requirements of General Condition B4.c are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. c. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of upset must demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (1) An upset occurred and that the permittee can identify the causes(s) of the upset; (2) The permitted facility was at the time being properly operated; (3) The permittee submitted notice of the upset as required in General Condition D5, hereof (24-hour notice); and (4) The permittee complied with any remedial measures required under General Condition A3 hereof. d. Burden of proof. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof.

B5. Treatment of Single Operational Upset For purposes of this permit, a single operational upset that leads to simultaneous violations of more than one pollutant parameter will be treated as a single violation. A single operational upset is an exceptional incident that causes simultaneous, unintentional, unknowing (not the result of a knowing act or omission), temporary noncompliance with more than one federal Clean Water Act effluent discharge pollutant parameter. A single operational upset does not include federal Clean Water Act violations involving discharge without a NPDES permit or noncompliance to the extent caused by improperly designed or inadequate treatment facilities. Each day of a single operational upset is a violation.

B6. Overflows from Wastewater Conveyance Systems and Associated Pump Stations a. Definition. "Overflow" means any spill, release or diversion of sewage including: (1) An overflow that results in a discharge to waters of the United States; and (2) An overflow of wastewater, including a wastewater backup into a building (other than a backup caused solely by a blockage or other malfunction in a privately owned sewer or building lateral), even if that overflow does not reach waters of the United States. b. Reporting required. All overflows must be reported orally to DEQ within 24 hours from the time the permittee becomes aware of the overflow. Reporting procedures are described in more detail in General Condition D5.

Permit Number: 1200-Z Effective: August 1, 2017 Reissuance: October 22, 2018 Expiration: June 30, 2022 Page 123 of 129

B7. Public Notification of Effluent Violation or Overflow If effluent limitations specified in this permit are exceeded or an overflow occurs that threatens public health, the permittee must take such steps as are necessary to alert the public, health agencies and other affected entities (for example, public water systems) about the extent and nature of the discharge in accordance with the notification procedures developed under General Condition B8.

Such steps may include, but are not limited to, posting of the river at access points and other places, news releases, and paid announcements on radio and television.

B8. Emergency Response and Public Notification Plan The permittee must develop and implement an emergency response and public notification plan that identifies measures to protect public health from overflows, bypasses, or upsets that may endanger public health. At a minimum the plan must include mechanisms to: a. Ensure that the permittee is aware (to the greatest extent possible) of such events; b. Ensure notification of appropriate personnel and ensure that they are immediately dispatched for investigation and response; c. Ensure immediate notification to the public, health agencies, and other affected public entities (including public water systems). The overflow response plan must identify the public health and other officials who will receive immediate notification; d. Ensure that appropriate personnel are aware of and follow the plan and are appropriately trained; e. Provide emergency operations; and f. Ensure that DEQ is notified of the public notification steps taken.

B9. Removed Substances Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of wastewaters must be disposed of in such a manner as to prevent any pollutant from such materials from entering waters of the state, causing nuisance conditions, or creating a public health hazard.

SECTION C. MONITORING AND RECORDS C1. Representative Sampling Sampling and measurements taken as required herein must be representative of the volume and nature of the monitored discharge. All samples must be taken at the monitoring points specified in this permit, and must be taken, unless otherwise specified, before the effluent joins or is diluted by any other waste stream, body of water, or substance. Monitoring points must not be changed without notification to and the approval of DEQ. Samples must be collected in accordance with requirements in 40 CFR part 122.21 and 40 CFR part 403 Appendix E.

C2. Flow Measurements Appropriate flow measurement devices and methods consistent with accepted scientific practices must be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The devices must be installed, calibrated and maintained to insure that the accuracy of the measurements is consistent with the accepted capability of that type of device. Devices selected must be capable of measuring flows with a maximum deviation of less than ± 10 percent from true discharge rates throughout the range of expected discharge volumes.

Oregon Department of Environmental Quality iv Industrial Stormwater Best Management Practices Executive Summary This document is designed to aid in the selection and implementation of best management practices for the protection of water quality affected by industrial stormwater discharges.

Best management practices, or source controls, are practices and/or procedures to prevent pollution in stormwater discharge, including methods to prevent toxic and hazardous substances from reaching re- ceiving waters. They are designed to address the quality of a facility’s practices and may ultimately af- fect the ability of the facility to meet effluent limits, impairment and sector-specific reference concentra- tions and/or benchmarks. Best management prcatices are most effective when organized into a compre- hensive stormwater pollution control plan. Several different source controls can be used to achieve simi- lar environmentally protective results. With facility-specific or activity-specific pollutant(s) of concern as the major consideration(s) in selecting appropriate best manaegement prcatices, facilities can tailor a stormwater pollution control plan to achieve permit compliance with available technologies.

The best management practices included in this document address activities and operations that take place outdoors and do not address pollutants from indoor industrial production. These practicess are to be considered a work in process and are by no means a complete list of appropriate pollution control measures. DEQ may periocically add other best management practices to this document.

Oregon Department of Environmental Quality 1 Industrial Stormwater Best Management Practices Introduction Background: Under the Total Daily Maximum Load, or TMDL, program states must list waterbodies not meeting wa- ter quality standards and to determine, for each degraded waterbody, the “total maximum daily load” of the problematic pollutant that can be allowed without violating the applicable water quality standard. The regulating community or agency then determines what types of additional pollutant loading reduc- tions are needed, considering not only point sources but also nonpoint sources. The regulator then estab- lishes controls on these sources to ensure further reductions to achieve applicable water quality goals. National Pollutant Discharge Elimination permit conditions must respond to federal U.S. Environmental Protection Agency stormwater requirements, as well as TMDLs, which have been mandated by Con- gress to regulate stormwater discharges more rigorously. Locally in 2007 and 2008, two environmental advocacy groups, Northwest Environmental Defense Center and Columbia Riverkeeper, challenged the validity of the Oregon’s current industrial permits under the federal Clean Water Act. DEQ revised the industrial NPDES permit as part of a settlement agreement and implemented significant changes.

Organization: This is a ‘living document’ with new additions generally added at the document’s end. Table 1, follow- ing the Reference section, is organized by type of activity and provides an index to the numbered best management practices for easy access to the body of information.

Best Usage: The best way to use this guide is to assess your site’s activities that affect your stormwater discharge(s), using Table 1. Determine the pollutants in the stormwater discharge(s) and the potential sources of those pollutants on site, then determine which potential sources have the most significant impact on the dis- charge(s). Select a best management practice or practices that will be most effective in controlling pollu- tion in the stormwater discharges, while being practical about resources and costs that will be required to implement and maintain those practices. After you install selected best management practices, sample the stormwater discharges to verify reduced pollutants and determine if additional practices will be nec- essary to meet permit monitoring requirements for the various pollutants of concern. [Caution: The effi- ciencies provided in this document should be used as indicators of the potential pollutant reduction re- lated to best management practice installation. The efficiencies can be variable depending on a number of factors including flow, maintenance of the best management practice, loading and other factors.]

Low Impact Development began in Prince George’s County, Maryland in 1990 as an alternative ap- proach to the no longer cost-effective detention ponds and basin on construction sites. The concept has become the preferred method of stormwater management because engineered small-scale hydrologic controls replicate pre-developed conditions through infiltration, filtration, storage, evaporating and de- taining water close to its original source. Often space is a limiting factor for industrial facilities’ use of low-impact development controls. Other limitations include: soil conditions, climate, groundwater lev- els, cost and maintenance. DEQ promotes the use of low-impact development practices to reduce stormwater flows and control the mass load of pollutants that enter the receiving stream. In addition, if an industrial facility can capture and treat and/or infiltrate all stormwater without discharging to waters of the state or a conveyance system that discharges to waters of the state, that facility may be eligible for termination of NPDES permit coverage. Low-impact development options include:

• Bioretention Areas • Dispersion or Swales • Vegetated Roofs • Permeable Pavements or Pavers • Roof Rainwater Collection Systems (for re-use)

Underground Injection Control places fluids below the ground through dry wells, drill holes, soaking Oregon Department of Environmental Quality 2 Industrial Stormwater Best Management Practices

trenches and infiltration facilities with under drains. Any infiltration facility is a UIC if it is deeper than the facility is wide. Oregon Association of Clean Water Agencies hired Kennedy/Jenks Consultants to evaluate stormwater data before entering UIC devices. This report use data from five municipalities around Oregon, Clackamas County, Gresham, Redmond, Bend and Portland to provide DEQ with groundwater protectiveness models to demonstrate UICs do not pose a likely adverse risk to groundwa- ter. This report and other factors reaffirm that injection systems to dispose of water that may come in contact with any raw material, product, byproduct or waste during manufacturing or processing may be a viable option while protecting groundwater under the Safe Drinking Water Act federally enacted in 1974. If all stormwater can be injected into the ground, permitting will be addressed through the under- ground injection control program and the facility may be exempt from NPDES permitting. All under- ground injection controls must be registered and approved for issuance through either a water pollution control facility (WPCF) permit or authorized by rule. Stormwater may be managed through underground injection systems provided conditions established in rule can be met. Some industrial activities which may inhibit use of groundwater injection include:

• Vehicle washing, maintenance, repair and recovery • Airport de-icing • Storage of treated lumber • Facilities handling hazardous materials or improper storage and containment or chemicals • Sites under Resource Conservation and Recovery Act (RCRA)

Oregon Department of Environmental Quality 3 Industrial Stormwater Best Management Practices phoned to a vegetated area so that complete percolation into the ground occurs. An impermeable fabric liner may be needed for the lagoons or constructed wetlands to protect groundwater. All criteria set forth in OAR 340-40 must be met for groundwater quality protection. Treatment options include, but are not limited to: • grit trap for suspended solids removal • oil/water separator removes floating oil • ph adjust unit will neutralize acids and caustics • advance treatment alternatives

 The treatment system must be, at all times, properly operated and maintained. Records of mainte- nance activities should be maintained on-site for DEQ inspection.

2. Disposal of wash water should occur on ground surfaces with vegetated cover and may not cause any erosion. Depending on the amount of vehicles washed in a week, a permit may be required.

3. If facility is close to surface waters the wash water may be disposed to a dry grassy swale, a mini- mum of 250 feet in length before the waterbody. Complete percolation in the swale should occur with no direct discharge to the surface water. Discharge into a grassy swale for treatment should not occur with- in 24 hours after a rainfall event or if water remains ponded in the swale. A distance of 250 feet was based on a hydraulic conductivity of 0.2 gal/ft/day, volume per day of 150 gallons, and a swale with a width of 3 feet.

Efficiency/Impact: The use of a recycling system will not only reduce or eliminate the contaminant discharge to stormwater or sanitary sewer but it will greatly reduce the amount of water used in the process. The use of a bioswale with an oil/water separator will likewise virtually eliminate the total suspended solids, oil and grease, and heavy metals discharged provided both are properly sized. A portable collection system will provide the collection of the contaminants provided the collection system is large enough to capture significant amounts of the overspray.

BMP 9 Oil/Water Separators

Activity: Any site that has steel, equipment or vehicles stored outside and has a potential for oily storm water discharges.

Typical Pollutants: Oil and grease, PAH, and suspended solids

Typical Problem: Structural steel and plate arrives on the site from the supplier coated with oil to in- hibit corrosion. As storm water comes in contact with the steel the oil disperses and runs off. Equipment stored outside has grease and oil on it that washes off when contacted by storm water. Vehicles not only have the normal oil and grease associated with them but they also have road film which contains oil.

Oregon Department of Environmental Quality 15 Industrial Stormwater Best Management Practices

BMP: Installation of a properly sized oil/water separator can reduce the amount of both Total Suspended Solids and Oil and Grease in the storm water run-off. Sev- eral types of oil/water separators are available (Gravity, Coalescing, Centrif- ugal, Carbon Absorption, Ultrafiltration, etc.). Gravity Oil/Water Separators are generally the most economical provided emulsifying chemicals have not been used upstream of the separator, dirt is not a major contaminant, and high shear centrifugal pumps are not used to pump the water to the separator.

There are three basic types of oil/water separators, spill control (SC), API (longer retaining time), and coalescing plate (CPS) recommended for use in all pipe drainage systems conveying runoff from paved areas, subject to vehicular use or storage of chemicals, prior to discharge from the project site or into an open drainage feature. All three types have the following basic applica- tion/selection criteria:

• Urban residential runoff usually low flows • Suitable for smaller sites, draining 5 or less acres • Land uses associated with include: industrial, transportation, log storage, airports, fleet yard, railroad, gas station, vehicle/equipment dealers and repair, construction and petroleum stor- age. • SC can be effective at retaining small spills but does not remove dispersed oil droplets be- cause they have a short residence time. SC type should be required when the site stores petro- leum based products and spills are likely.

API used where there is a relatively high likelihood of dispersed oil contamination. API/CPS should be used in areas with high traffic volumes (2,500 vehicles per day), at sites that are used for petroleum storage/transfer, scrap and wrecking yards, or at sites where heavy equipment is stored and/or maintained. Oil/water separators cannot deal well with heavy sediment loads and should be used in conjunction with detention, biofiltration, or water quality treatment system to protect groundwater. CPS consist of a bundle of plates made of fiberglass or polypropylene installed in a concrete vault. The plates improve the removal of oil and fine suspended sediments and assist in concentrating the pollutants for removal. CPS requires frequent inspection and maintenance to operate as designed. A mechanism should exist for the system to be bypassed, so the system can be taken off line for maintenance. Oil and sediment removed from devices may qualify as hazardous waste and should be tested prior to disposal. Oil separators should be sized for a local six-month reoccurring 24-hour de- sign storm. Larger storms should be diverted from the separators.

Efficiency/Impact: The use of gravity oil/water separators in the storm water outflow can greatly re- duce the free oil droplets larger than 0.015cm (150 microns). Ultrafiltration can virtually eliminate oil in the storm water outflow. Fouling of membranes may be- Oregon Department of Environmental Quality 16 Industrial Stormwater Best Management Practices

come a concern with Ultrafiltration although some newer vibrating membranes show great promise for keeping the membranes clear during backflushing.

BMP 10 Oil/Water Separators for Air Compressors

Activity: The use of compressed air.

Typical Pollutants: Oil

Typical Problem: Compressed air systems typically absorb or condense moisture from the ambient air. Fine oil is released to the compressed air in the compression cycle. The con- densed water is either manually drained out of the compressor, filters, and/or the air receiver tank or is automatically drained by a timed valve system. This con- densate may be discharged to the ground or to a location that can leak or be spilled into the outside environment. Storm water then flushes this oil to the storm water outfall.

BMP: Install an oil/water separator especially made for compressors and receiver tanks or manufacture a simple separator similar to the one shown on the following page and siphon off the oil. Dis- charge the remaining water to the sanitary sewer if it is available on-site.

Efficiency/Impact: Oil from this source can be greatly reduced or eliminated and loading to the storm water conveyances will be reduced.

BMP 11 Oil and Sediment Trap Catch Basins

Activity: Storm water runoff from commercial or industrial sites to standard catch basins or drains.

Typical Pollutants: Oil, PAH, and sediment

Typical Problem: On sites that use standard catch basins or drains there is no retention of any oils or sediments. This could result in excessive discharges to storm water of these pollu- tants.

Oregon Department of Environmental Quality 17 Industrial Stormwater Best Management Practices

BMP: Retrofitting drains to standard sediment and oil trap (Lynch style) catch basins properly designed for the flow-through rate and when properly maintained can reduce oil and grease levels in the storm water discharge significantly.

Efficiency/Impact: Proper sizing and maintenance can reduce the discharge concentrations of oil and grease to below 10mg/l and suspended sol- ids including heavy metals by from 10% to 42% depending on the influent flow rate and the accumulated sediment level al- ready in the lower sump with the lower ef- ficiency corresponding to the higher flow rates. It is extremely important to remove the accumulated sediments and oil in the catch basin when the sediment retention capacity (depth below the bottom of the outfall pipe) is reduced by 50 % but to a depth of not less than 18 inches to the outfall pipe.

Note: An additional issue on some industrial sites is the lack of a single or common sampling point which may require that sampling be accomplished from the catch basin(s). The catch basin is typically the worst place to sample in that it is where the pollutants are concentrated and retained and it is not really representative of the pollutant concentrations leaving the site. Sometimes an insert bag may be used in the catch basin as a BMP to remove sediments. Moving this bag to the side typically re-suspends TSS that was clinging to the bag thus increasing the TSS in the sam- ples collected. Consider using a pipe Tee instead of an inverted elbow or flat steel invert/cleanout in the catch basin outfall. If the pipe and tee are four inches or more in diameter, it is possible to dip the sample bottle in the clean side of the catch basin and if the tee where extended up through the grate and a removable cap was place upon it, the insert bag would not have to be disturbed nor would the grate have to be removed in order to sample. Another option for sampling is to ex- cavate to the outfall piping on the discharge side of the catch basin and replace the a section of the 45 degree angled drain pipe with a sampling sump with access to a sealed cover at ground level. The depth to the angled outfall pipe would probably be around 18 inches or less in most cased.

An alternative to introducing ozone is the use of ultraviolet light disinfection to control microbial growth in cooling tower water. In this case the cooling tower is recirculated through the UV unit which kills organisms attempting to grow in the water. Blowdown will still have to occur but will probably be required at a reduced frequency over that necessary when chemicals are used. The computer chip industry has used this method for their ultrapure water processes for years and the machinery coolant recycling equipment industry has also been using UV treatment units to eliminated biological growth in their coolant recycling equipment.

Efficiency/Impact: By replacing chemical additives with ozone or UV treatment and using a swim- ming pool vacuum cleaner for sediment removal, potential pollutants from this source to the storm water conveyances can be reduced or eliminated.

BMP 14 Cartridge Filtration

Activity: Operations with exposed copper and/or galvanized piping, galvanized siding and/or roofing materials, cathodic protection coatings of copper such as may be found on boats, or other exposed copper, brass, and/or zinc coated materials that are exposed to storm water may have significant levels of these metals present in their storm water discharge. Operations in- volving heavy vehicle traffic may also have metals in their storm water discharge such as copper from brake shoes and clutches or zinc from tire wear.

Vault type filters

Oregon Department of Environmental Quality 21 Industrial Stormwater Best Management Practices

Typical Pollutants: Copper, zinc, PAH, and Total Suspended Solids

Typical Problem: Dust from tires (1% Zinc wear rate = 90mg/km/tire) and clutch/brake mecha- nisms, deterioration from galvanized building materials or corrosion and/or oxida- tion of copper piping and fixtures cause discharges of particulate and dissolved chemical forms of copper and zinc to the environment when contacted by storm water. Copper based cathodic protection on boats and other equipment generates chemical and particulate forms of copper that becomes combined with storm wa- ter.

BMP: The installation of properly sized compost filtration units can remove significant amounts of both chemical and particulate forms of some heavy metals, including copper and zinc, and reduce TSS levels in the storm water discharge. Colloidal particulate levels from clay soils should also be re- duced effectively.

Effectiveness/Impact: Evaluation of existing sites over a three-year period show that the mean reduc- tions of pollutants in storm water for the following were achieved:

For Compost Media

TDS 22.4% Turbidity 91.8% COD 70.4% Total Phosphorus 44.9% Lead 44.9% Zinc 83.2% Copper 65.3% Oil & Grease 80.9%

In general, reductions for Heavy Metals can be expected to be in the range of 65 to 95% and for Oil & Grease up to 85% for a properly designed and sized system.

Oregon Department of Environmental Quality 22 Industrial Stormwater Best Management Practices

BMP 15 Sweeping

Activity: Operations that have exposed copper and/or galvanized piping, galvanized siding and/or roofing materials, or other exposed copper, brass, and/or zinc coated materials exposed to storm water can have significant levels of these metals present in the storm water discharge. Operations involving heavy vehicle traffic also produce elevated metal levels in storm water from vehicle brake shoes or clutches (copper) and tire particles (1% zinc wear rate = 90mg/km/tire).

Typical Pollutants: Total Suspended Solids, PAH, Copper, Zinc.

Typical Problem: Dust from tires and clutch or brake mechanisms, deterioration from galvanized building mate- rials, or corrosion and/or oxida- tion of copper piping and fix- tures cause discharges of par- ticulate and dissolved chemical forms of copper and zinc to the environment when contacted by storm water. Copper based ca- thodic protection on boats and other equipment also generate dissolved chemical and particu- late forms of copper that can become combined with storm water.

BMP: Sweeping of paved roads, parking lots, and storage areas with a type of vacuum sweeper that in- corporates HEPA filtration or other high efficiency method of filtration of the exhaust air from the sweeper to trap the very fine metallic particles found in road or parking lot dust can reduce these discharges to storm water.

Ensure that good control measures are implemented when dumping the contents of the sweeper and practice proper disposal methods for the emptied contents to ensure that there is no adverse environmental impact after spending so much effort in the initial clean-up. Oregon Department of Environmental Quality 23 Industrial Stormwater Best Management Practices

Efficiency/Impact: This type of Sweeper is capable of collecting and containing up to 99.6% of parti- cles as small as 2.5 microns in size. The elimination of particulates in storm water is related to the frequency of sweeping as is shown comparisons of various types of sweepers in the following graph.

There are sweeper certifications, PM-10 and AQMD, which both are high effeciency sweepers that can contain small particle sizes. Some models, as shown below, contain hoppers which can be emptied directly into a dumpster or dump and debris as it is picked up from the floor and passed through a polyester filter. When the hopper is full, it can be emptied directly into a dumpster or dump truck, mini- mizing the chance of particulate matter being re-released into the air. Information from the manufacturer, reports that the sweepers will retain particles 10 microns, or 0.001 mm, or larger. The smaller size of the model and four-wheel steering makes it easy to maneuver in small spaces that traditional sweepers would not fit.

BMP 16 Battery Storage

Activity: The outdoor replacement or storage of lead/acid or nickel/cadmium batteries and the long time storage of vehicles or battery powered equipment outside.

Typical Pollutants: Soluble metals such as lead, nickel, or cadmium, Sulfuric acid

Typical Problem: When batteries are replaced, the used batteries are generally stored around a site until enough have been collected to make it feasible to either have them picked up or shipped out to a battery recycler. These batteries are usually stored on the shop floor or outside without containment and with no thought of exposure to storm water. Sometimes electric lift trucks, pallet jacks, welders, portable powered pumps, etc. are stored outside with the batteries used for starting or for operation left in place and poorly protected from storm water contact. Lead sulfate usually present on lead/acid batteries or in the spillage of the lead/acid or nickel-cadmium/acid solution can create soil contamination and a storm water run-off problem.

Oregon Department of Environmental Quality 24 Industrial Stormwater Best Management Practices

BMP: Batteries should be stored in a contained area protected from the weather. Containment pallets can be used to collect any acid spillage. The pallets should be placed inside of buildings to keep storm water from coming into contact with the batteries.

Efficiency/Impact: Containment, protection from the weather, and frequent shipment to the recycler can minimize or eliminate the adverse storm water impact from this potential source of contamination.

BMP 17 Wrecked Vehicle Storage & Scrap Metal Recycling

Activity: Wrecked or Damaged Vehicle Storage or Scrap Metal Recycling

Typical Pollutants: Antifreeze (ethylene glycol), gasoline, oil, grease, brake fluid, diesel

Oregon Department of Environmental Quality 25 Industrial Stormwater Best Management Practices

• In systems using filters, the filters, when full, shall be first wetted with a fine mist of water, then removed and placed immediately in an impermeable container, properly labeled and disposed.

• Any spills of asbestos-containing aqueous solution or any asbestos-containing waste material shall be cleaned up immediately and properly disposed.

• The use of dry brushing during low pressure/wet cleaning operations is prohibited.

Efficiency/Impact: Use of the wet method for removing the dust in the wheel/brake housing or the use of a HEPA vacuum will significantly reduce or eliminate this practice as a source for copper or asbestos in storm water. It will also significantly reduce the potential health hazard associated with asbestos exposure to employees.

BMP 21 Employee Environmental Training

Activity: Employee environmental education and training.

Typical Pollutants: All

Typical Problem: Many employees are not aware of the potential adverse impact the company’s busi- ness may have on the environment or how they personally can affect those impacts. They may not have even thought about environmental impacts and cannot recognize bad practices. Some may not know whom to inform of upsets or potential problems.

BMP: Provide periodic training that describes the potential adverse environmental impacts of the busi- ness and methods for preventing those impacts. The training should:

• Describe how the company is being environmentally responsible. • Encourage employees to bring forth suggestions for improving the environmental perfor- mance of the business. • Describe how and to whom the employee should report potential environmentally relate con- cerns. • Inform the employee of what to do. • Provide incentives to employees to offer ideas for improvement.

Record attendance of the training. Show graphics in the presentation such as pictures of the vari- ous parts of the site under discussion during the presentation. Schedule regular inspections of the site looking for possible conditions or operations that could produce potential adverse environ- mental impacts. Use a team approach to this inspection, as it is too easy, even for professionals, to acquire tunnel vision during the inspection. During the site inspections, write up every ques- tionable item or practice for later thought or resolution. To resolve or dismiss a suggestion or Oregon Department of Environmental Quality 30 Industrial Stormwater Best Management Practices

question during the inspection may distract from the process of the inspection or discourage em- ployees from providing their input. Do not associate biodegradable with environmentally safe. Verify that the company is not moving wastes from one media to another, i.e. water to air, storm water to groundwater, etc.

Before the training takes place, analyze the potential problem areas of the site and the potential for how the site’s manufacturing process can adversely impact the environment. Develop the training program presentation around these areas. Ask the question “what message am I trying to present?” and thoroughly provide the information necessary to answer the question. How and to whom should it be reported? Involve employees in the presentation through discussion items. Don’t over look providing this training to temporary employees.

Efficiency/Impact: By making employees aware of the potential adverse impacts of the business and encouraging employees to offer ideas and suggestions, employers will see, not on- ly a decrease in pollutants in their storm water discharge but, potentially in air, hazardous waste, and other media.

BMP 22 Housekeeping

Activity: Any site that stores material outside.

Typical Pollutants: Total suspended solids from erosion, oil and grease, BOD5, heavy metals.

Typical Problem: Poor housekeeping inside and outside on a site provide a possible indicator of the de- gree of the site’s compliance with environmental, health and safety regulations. In addition, poor outside housekeeping tends to discharge paper, cardboard, wood, pallet and box strapping, and other wastes to the storm water conveyance system. These wastes can plug the storm water conveyances, and divert storm water flows causing increased erosion and localized flooding.

Oregon Department of Environmental Quality 31 Industrial Stormwater Best Management Practices

BMP: Good housekeeping includes:

• Orderly storage of bags, drums, and piles of materials and chemicals; prompt cleanup of spilled liquids; • Frequent sweeping, vacuuming, or other cleanup methods for accumulated dry chemicals and materials can cut down on possible storm water contamination; • Proper disposal of toxic and hazardous wastes, and • Removal of accumulated scrap and spare parts.

Good housekeeping doesn’t just happen. It occurs when it is well planned, scheduled, and when upper management demonstrates its importance by participating in regular inspections. Set aside time in the work schedule for cleanup activities.

• Schedule personnel to be responsible for the cleanup and rotate every employee through the schedule. • Periodic inspections and regular site cleanup can prevent problems from occurring. The fre- quency of outside inspections should be increased during the October through May rainy pe- riod. • Encourage employees to pick up trash when it is seen and to report when more intensive clean up is needed.

Every site that is environmentally responsible has good housekeeping activities. Most sites with environmental problems do not have good housekeeping activities.

Efficiency/Impact: The implementation of a formal housekeeping program with education and encour- agement of employees can reduce or eliminate pollution by bringing the importance of how materials are stored and how trash can affect the storm water discharges to their attention along with the importance that management places on the issue. A regular maintenance schedule for storm water conveyances minimizes erosion and visually verifies the condition of the storm water discharges. Several typical pollu- tants in storm water can readily be identified by visual observance.

Oregon Department of Environmental Quality 32 Industrial Stormwater Best Management Practices

BMP 23 Lawn Care

Activity: Facilities having lawns or vegetated areas.

Typical Pollutants: Fertilizers, pesticides, herbicides, fungicides, phosphorus, nitrogen, zinc, copper, and pH.

Typical Problem: Lawn care entails the application of fertilizers, herbicides, pesticides, and water in order to achieve a rich vibrant lawn. Weeds are quite often controlled through the ap- plication of chemicals. Over fertilizing and the over-application of pesticides and herbicides can contaminate storm water. Too much irrigation can wash these chemi- cals off the site into storm water conveyances, streams, rivers, and lakes. The nutri- ents, phosphorus, nitrogen, and pH can be detrimental to slow moving water bodies by encouraging algae growth. Herbicides and pesticides can adversely impact human health, fish and other wildlife. All of these pollutants can significantly affect the ben- eficial uses of water bodies.

BMP: If a landscape contractor is hired to take care of the lawn and other vegetated areas of the site, ensure that they do their part to protect the environment by applying the appropriate amount of chemicals. Encourage them to investigate more environmentally friendly alternatives to the use of chemicals such as a thin layer of compost on top of the lawn in the fall.

A few simple precautions can minimize adverse environmental impacts from lawn care. No mat- ter what chemicals are used, over-watering can move the chemicals in to the storm water con- veyance system. Use rain measuring equipment to automatically prevent automatic lawn sprin- klers from turning on. In the Northwest, watering to a depth of six inches a couple of times a week is sufficient for a lush green growth. Always water in the morning, between 6 a.m. and noon, or in the evening around sundown so that the water has time to infiltrate before it evapo- rates

Fertilization:

For lawn fertilization, 1,000 square feet of lawn requires 0.5 pound of nitrogen per month of ac- tive growth(~8 months in Portland area ~ 4 pounds). A good ratio for fertilizer is 3 parts nitrogen Oregon Department of Environmental Quality 33 Industrial Stormwater Best Management Practices

to 1 part phosphorus to 2 parts potassium to 1 part sulfur (3:1:2:1). Use a slow release fertilizer such as one containing water insoluble nitrogen (WIN). After determining the amount of fertiliz- er to use per year based upon the growing season, apply the fertilizer in four equal applications of approximately one pound per 1,000 square feet each application, i.e. 1/4 in early spring, 1/4 in late spring, 1/4 in late summer, and 1/4 in the fall.

Have your site’s soil tested to determine if other materials such as iron (for low pH soil < 6.8), boron, chlorine, copper, manganese, molybdenum, nickel, and zinc should be added for a healthy lawn. If soil testing indicates that one or more of the additives above is needed, contact your county Extension Agent, a lawn and garden center, or a master gardener for advice on how much of the additives to apply for optimum growing conditions.

Fertilizer over-use, over watering, and watering at the wrong time of the day set up a good envi- ronment for many grass diseases and for invasion by weeds that are very competitive with the grasses in the lawn.

Pest Management:

Pest management can be conducted in an environmentally friendly manner through:

• Knowledge 1. knowing the variety of grass in your lawn; 2. knowing its growth characteristics; and

• Identification 1. identifying the weeds present; 2. identifying the grass disease present; and/or 3. identifying the insect pests present a). Note where the pest is located on the lawn b). Draw a picture of the pest or collect a sample i. Research in books for a match of the pest found to a photograph; ii. Contact local County Extension office for assistance and advice; or iii. Take sample to local home and garden center for identification.

Weed removal is best accomplished by hand-pulling.

Maintain a buffer strip next to waterways. Do not apply fertilizer or pesticides to this strip. It is used to absorb excess fertilizer from the care of the rest of the lawn. It will also retain excess nu- trients and sediments.

Healthy Lawn

Step 1: Lawn conversion Convert lawn areas into groundcover, trees, shrubs, or meadow plantings. For a low input approach, replace the grass underneath mature trees with groundcover. For an even lower input approach, examine your lawn for potential conversion areas and plant groundcovers, trees, shrubs, or perennials in all areas where grass is hard to grow. For the lowest input approach, use turf only where Oregon Department of Environmental Quality 34 Industrial Stormwater Best Management Practices

it is the best plant to fulfill a particular function, such as providing children’s sports area.

Step 2: Soil building Provide a strong foundation for the lawn. For a low input lawn, get a soil test to determine the soil's pH and fertility. You may not need to add any lime or fertilizer to your lawn. For a lower input lawn, test for soil compaction. Can you sink a screwdriver into the ground without pounding or is the soil compacted? If the soil is compacted, aerate with a hand corer or mechanical aerator. For the lowest input lawn, examine the soil's texture- neither extremely sandy soils nor extremely heavy clay soils make for good lawns. Next count earthworms - if none can be found in a square foot of soil, there's a problem. A healthy soil community has over 10 per square foot. With this basic understanding of soil acidity, fertility, compaction, texture, and earth-worms, one can build soil that sup- ports dense, healthy turf.

Step 3: Grass selection Choose the type of grass that will be easiest to grow. For a low in- put lawn, select hardy grass species adapted to your region's cli- mate. For a lower input lawn, select named grass varieties to meet your specific needs. For the lowest input lawn, try the new low in- put slow growing or dwarf grass mixes.

Step 4: Mowing and thatch Mow to the right height at the right time and recycle clippings. management For a low input lawn, leave clippings on the lawn to provide nutrients and moisture. For a lower input lawn, set mowing height as high as possible. For the lowest input lawn, adjust mowing height and fre- quency during the growing season and monitor thatch levels.

Step 5: Minimal fertilization Give the lawn what it needs but don't overfeed. For a low input lawn, recycle clippings and (in the right season) apply commercial fertilizer at half the recommended rate; avoid weed and feed for- mulations and don't fertilize if rain is imminent. For a lower input lawn, fertilize as above but use encapsulated nitrogen or an organic product instead and fertilize only if soil tests show it's needed. For the lowest input lawn, substitute home generated compost for commercial organic or encapsulated products.

Step 6: Weed control and Establish a realistic tolerance level for weeds and use less toxic tolerance control methods to maintain it. For a low input lawn use least toxic weed control methods such as: cultivation, solarization, flaming, mowing, or herbicidal soap. For a lower input lawn, grow strong healthy grass and it will crowd out weeds. For the lowest input lawn, broaden your definition of “lawn” to include weeds that per- form desirable functions.

Step 7: Integrated pest Establish a realistic tolerance level for pests and use least toxic con-

Oregon Department of Environmental Quality 35 Industrial Stormwater Best Management Practices

management trol methods to maintain it. For a low input lawn, use least toxic control methods such as removing or trapping pests, introducing biological control agents, or apply least toxic chemical controls such as insecticidal soaps. For a lower input lawn, grow strong, healthy grass that can resist attack. For the lowest input lawn, use cultural controls to prevent infestation, protect natural predators, and add beneficial soil microbes.

Step 8: Sensible irrigation Practice water conserving landscaping techniques. For a low input lawn, water infrequently, in the early morning, but soak the lawn well. For a lower input lawn, water only when the lawn definitely needs it, and calibrate sprinklers. For the lowest in- put lawn, accept that the grass may not be green year round.

Efficiency/Impact: Proper maintenance of lawns and vegetative strips can be pleasing to the eye and provide environmental benefits such as reduced pollution to streams, rivers, and lakes, cooler runoff, reduce sediments in the runoff, and in some cases reduce other pollutants from the site. The degree that this BMP will be effective is direct- ly proportional to the degree of involvement in the care of the lawn or the degree of caution exercised in selecting a lawn care contractor and the degree that the watering system is in tune with the lawn and the weather.

BMP 24 Dumpster Covering

Activity: Storage of general rubbish or food rubbish outside in dumpsters.

Typical Pollutants: Suspended solids, nutrients, bacteria, dioxin, chemicals

Typical Problem: Waste materials are typically removed from inside the site buildings to a collection container (dumpster) outside of the buildings. If these dumpsters have an open top or the top is left open at times when materials are not being dumped into them, storm water makes contact and will mix with the wastes and leak out to the storm water dis- charge conveyances for the site.

Oregon Department of Environmental Quality 36 Industrial Stormwater Best Management Practices

BMP 30 Catch Basin Insert Bag

Activity: Sites with surface water runoff contamination that have implemented specific non-point source BMPs for pollution prevention but have been un- able to reduce the pollutant discharges in their storm water runoff to levels below the bench- marks. Unused excess land may be necessary to implement these BMPs.

Typical Pollutants: Sediment (TSS), PAH, metals, BOD, phosphorus, and hydrocarbons (Oil & Grease)

Typical Problem: When the implementation of specific point source BMPs has not eliminated or re- duced the contaminants in the storm water to the specific benchmarks, end of the pipe or final discharge BMPs may be necessary.

BMP: Install a catch basin filter system (normal flow) without overflow slots in the filter media: a catch basin coupled with a sump and sediment traps (i.e. trapped or Lynch style catch basins). May also be used with an inlet device, prefiltering insert and screens (see other facilities and ret- rofit). The inserts consist of several filtering trays suspended from the inlet grate. Common filters are charcoal, wood fibers or fiberglass.

• Retains small particles, partially effective with high levels of particulate heavy metals, oil/grease, and TSS. Moderate reduction in TSS and turbidity. However, few pollutants are associated with these coarser solids. • Disadvantage: When 60% full, the suspended solid deposition is in equilibrium with scour, and the capture efficiency is reduced to zero. • Best in small basins and with treatment of highly turbid runoff prior to discharge to catch ba- sin. • Do not use on unstable or steep slopes. • Usually used with vaults, tanks, sumps or inverted (hood) inlet. Inlet can be coupled with a filtration system (see retrofit). • Maintenance is critical and must be at least semiannual. Require a maintenance schedule and plan for disposal of material removed by the catch basin. • Insert maintenance is required quarterly and should be inspected more frequently during wet periods. • Catch basins with a restrictor device (multiple orifice and weir/riser section) for controlling outflow provide minimal control for floatables and petroleum based products. • Design the size of catch basin sump to handle the site runoff rate, TSS concentration in run- off and how often it will be cleaned out. • To minimize groundwater pollution problems, be careful where infiltrating catch basins are used (residential areas) and pre-treat the infiltration water. • Using a Catch Basin Insert Filter Bag with a bypass or overflow is not recommended as they tend to bypass the inflow almost all of the time. Even during a relatively small rainfall event the types of catch basin insert bags with an overflow or bypass will tend to bypass on trapped (Lynch) type catch basins a significant amount of the runoff

Oregon Department of Environmental Quality 44 Industrial Stormwater Best Management Practices

thereby eliminating the benefits of using this BMP. Using an insert bag without an over- flow or bypass may result in flow back up and cause temporary local flooding unless the bag has the largest surface area (filtering area) inside of the bag possible for the size of the catch basin in which it is used.

Efficiency/Impact: Catch Basin Filter System Efficiency: TSS up to 22%, and Turbidity up to 38%

BMP 31 Constructed Wetlands

See the Biofilters document at http://www.deq.state.or.us/wq/stormwater/docs/nwr/biofilters.pdf for further information on Constructed Wetlands.

Activity: Sites with surface water runoff contamination that have implemented specific non-point source BMPs for pollution prevention but have been unable to reduce the pollutant dis- charges in their storm water runoff to levels below the benchmarks. Unused excess land may be necessary to implement these BMPs.

Typical Pollutants: Sediment (TSS), PAH, metals, BOD, phosphorus, and hydrocarbons (Oil & Grease)

Typical Problem: When the implementation of specific point source BMPs has not eliminated or re- duced the contaminants in the storm water to the specific benchmarks, end of the pipe or final discharge BMPs may be necessary.

BMP: Install a constructed wetland. Constructed wetlands are constructed by a combination of excava- tion and/or berming. The basic types of constructed wetlands are: shallow marsh, a 2 or 3 celled pond/marsh, extended-detention wetland and pocket wetland.

Storm water treatment facilities are not considered waters of the State, however, their discharge is regulated in the same way as any treatment system. Created wetlands built as mitigation for loss of wetlands under the Clean Water Act Section 404, are considered waters of the State. Cre- ated wetlands are protected as natural wetlands and cannot be used for conveyance or treatment of wastewater, unlike constructed wetlands.

• Extended-detention wetland and pocket wetlands are less effective in removal of some types Oregon Department of Environmental Quality 45 Industrial Stormwater Best Management Practices

of pollution than other types of wetlands. • The constructed wetland should be lined when located over permeable soils for permanent pool maintenance. This is to prevent potential groundwater and soil contamination. Use a Bentonite clay (12” thick) or commercial heavy plastic pond liner (minimum 40 ml). Place a minimum of 18” thick compacted soil over the liner prior to seeding. • The permanent pool depth should be between three to six feet in depth, plus one foot of dead storage for sediment. Six feet is the maximum depth or the pond will stratify in summer and create low oxygen conditions which result in the re-release of phosphorus and other pollu- tants. In addition, if the pond is deeper than six feet, it will likely pollute the groundwater. • Suitable for larger sites up to 100 acres. • Soils should be tested to determine suitability. Best when located in clay loams, silty clay loams, sandy clays, silty clays and clays. • Cannot be used in areas with shallow depth to bedrock or unstable slopes. • Good for removal of nutrients and conventional pollutants such as oil and grease and some heavy metals. • Needs to have a shallow marsh system in association to deal with nutrients. • Should be multi-celled, preferably three of equal sizes. The first cell should be three feet deep to trap coarse sediments and slow turbulence. They need to be designed as a flow through facility, and the pond bottom should be flat to facilitate sedimentation. • Need to be designed with periodic maintenance in mind by using an overhead scooping de- vice. • Side slopes should be 2:1, not steeper than 3:1, and 10 to 20 feet in width. A length to width ratio of 5:1 is preferred, with a minimum ratio of 2:1 to enhance water quality benefits. The longer length allows more travel time and opportunity for infiltration, biofiltration and sedi- mentation. • Pond berm embankments over six feet should be designed by a registered engineer. Berm tops should be 15 feet wide for maintenance access and should be fenced for public safety. • Shape should be long, narrow, and irregular since these are less prone to short circuiting, are more effective, and maximize the treatment area. • Baffles can be used to increase the flow path and water residence time. • Should have an overflow system/emergency spillway to accommodate a 100 year, 24 hour flood and a gravity drain. • Maintenance is of primary importance. The site must be responsibly selected. A maintenance plan needs to address removal of dead vegetation (that release nutrients) prior to the winter wet season, debris removal from trash racks, sediment monitoring in forbays and in basin are likely to contain significant amounts of heavy metals and organics (regular testing is ad- vised). • Access to the wet pond is to be restricted with a gate and posted signs. • For mosquito control, either stock the pond with fish or allow it to be drained for short peri- ods of time (do not kill the marsh vegetation). • Constructed wetland is more complex, with more vegetation, and shallower with greater sur- face area, hydrologic factors (flow) play a larger part in siting. • Selection of vegetation should be done by a wetland specialist. • Oil/water separators can be used prior to the constructed wetland, depending upon the sur- rounding land uses. • Relatively low maintenance costs. • Fence off for safety (children), to protect plants/wildlife. Oregon Department of Environmental Quality 46 Industrial Stormwater Best Management Practices

• Disadvantages/constructed wetlands: a.) Constructed wetlands have a larger land requirement for equivalent service compared to a wet pond. b.) Relatively high construction costs. c.) Delayed efficiency until plants are well established (1–2 seasons). • Buffer width 25 to 50 feet. • Limit water level fluctuations, as they kill plants.

Efficiency/Impact: Wet pond/wetland removal efficiencies:* a) Heavy metals = 40 to 80%; b) Total Phosphorus = 40 to 80% c) Total Nitrogen = 40 to 60% d) TSS = 70% e) Soluble reactive phosphorus 75% f) Nitrate = 65% g) Ammonia = -43 h) COD = 2 i) Total copper, lead and zinc = 80 to 95%

* Higher efficiencies are associated with use of O/G trap, larger pond/marsh area and volume. These efficiencies assume that the intensity of the storm water inflow does not exceed the capacity of the wetlands and that the pollutants are not in a concentrated form from a large spill or discharge.

BMP 32 Bioswales

See the Biofilters document at http://www.deq.state.or.us/wq/stormwater/docs/nwr/biofilters.pdf for further information on Bioswales.

Activity: Sites with surface water runoff contamination that have implemented specific non-point source BMPs for pollution prevention but have been unable to reduce the pollutant dis- charges in their storm water runoff to levels below the benchmarks. Unused excess land may be necessary to implement these BMPs.

Typical Pollutants: Sediment (TSS), PAH, metals, BOD, phosphorus, and hydrocarbons (Oil & Grease) Oregon Department of Environmental Quality 47 Industrial Stormwater Best Management Practices

Typical Problem: When the implementation of specific point source BMPs has not eliminated or re- duced the contaminants in the storm water to the specific benchmarks, end of the pipe or final discharge BMPs may be necessary.

BMP: Install a grassy bioswale. Swales basically act as filters for runoff from frequent storms. The principle form of treatment is the settling out of pollutants and the use of vegetation to take up the dissolved fraction. For best results a swale should be designed to deal with the peak runoff for a two year, 24 hour storm event.

• Does well with first flush runoff, economically feasible, improves aesthetics and has minimal environmental impacts. Best in median strips and parking lot islands. • The organic topsoil layer is good for degrading petroleum solvents, heavy metals, nutrients and hydrocarbons. • Critical design elements: size of drainage area to be treated, location of bioretention areas, sizing guidelines, calculate water budget. • Biofiltration is suitable for smaller sites 10 or less acres. • Needs a minimum width of 20 feet. • Must be graded to create sheet flow, not a concentrated stream. Sheet flow decreases the chance of producing gully erosion and distributes contaminants over a wider area. Level spreaders (i.e. slotted curbs) can be used to facilitate sheet flow. • Can be placed anywhere with careful site design. • Do not use on steep, unstable slopes or landslides. • Can reduce peak flow rates. • Best when used for treatment and conveyance of storm water after a settling pond. • Good for nutrient removal and conventional pollutants such as suspended solids and some heavy metals. • Best at 200 feet in length, in tight spaces obtain more length by using a curved path. Should have a maximum bottom width of 50 feet. One foot high check dams should be installed eve- ry 50 feet starting 20 feet downstream from the inflow point. • Good when used at a storm water outfall, commercial development or roadside.

Efficiency/Impact: Bioswales can, when sized correctly and when incorporated with an upstream set- tling pond, provide similar pollutant removal efficiencies to those achieved by a biopond or constructed wetland.

Removal efficiencies: a) TSS = 83 to 92% b) Lead = 67% c) Copper = 46% d) Total phosphorus = 29 to 80% e) Total zinc and aluminum = 63% g) Oil/grease/TPH = 75% h) Nitrate-N = 39 to 89%

Stormwater Pollution Control Plan November 2018 Metro South Station MSS HHW Emergency Containment Tank SOP

Metro has two underground emergency containment tanks at the Metro South Station Household Hazardous Waste Collection (HHW) facility. These tanks were installed to collect fire sprinkler water and or a potential spill. However, these tanks might also collect some rain water that is driven under the receiving and loading canopies.

Tank 1: Is in the landscaping between the Tank 2: Is by the stairs leading down from the receiving bay and the driveway and has a back loading dock to the tunnel and has a capacity to store 4,000 gallons at a depth of 72- capacity to store 2,500 gallons at a depth of 72- inches. The bay dips slightly towards the inches. It collects overflow from the back dock middle outside wall and into a catch basin that area through the Trench drain at the base of the drains to the tank. dock.

Overflow Tank 1 for Receiving Bay Overflow Tank 2 for Loading Dock

Metro HHW staff will check each tank monthly for water depth and record the depth on the Monthly Checklist. (Depth will be measured with a marked pole that is kept behind the receiving bay wall). Tanks will be pumped out if there is 15-inches or more of water in the bottom (which is about 600 gallons). The tanks will also be pumped if there is a spill or a fire sprinkler release that might have entered them.

Rain water in the tanks will be pumped to storm drains in the driveway, using the facility’s sump pump, if there is no reason to believe the sumps are contaminated (i.e. there has been no spills or fire sprinkler releases that could have entered the tanks). The date and estimated volume of rain water pumped to storm drains from the tanks will be recorded on the Monthly Checklist.

Metro will contract with a local laboratory to sample and test the water in the tanks in the event that there has been a spill or fire sprinkler release that might have entered a tank. Metro will review the results of testing and decide whether it is appropriate to transfer the tank contents to storm water, or will contract with a local pumping service to have the tank contents removed for appropriate treatment and or disposal. The details of any spill or fire sprinkler release and subsequent testing and pumping, will be reported on the Monthly Checklist and laboratory reports and invoices for treatment or disposal will be attached.

Metro will retain records of monthly inspections, the date and estimated volume of rain water pumped to storm drains, laboratory reports of any sampling and testing of tank contents, and invoices for any treatment and or disposal of water from the tanks. These records will be scanned each month to an Adobe file named MSS.HHW.MonthlyChecklist.dd.mm.yy.pdf, and stored on Metro’s electronic network. The Metro South HHW facility supervisor will be responsible for ensuring that these records are correctly maintained and available at the facility for regulatory inspectors.

. What is stormwater? . Why is stormwater discharge regulated? . Stormwater permit requirements . Permit enforcement . Pollution prevention What Is Stormwater?

. Definition: Rain or snow melt that “runs off” or travels across land and does not infiltrate. What Is Stormwater?

. Different from wastewater:

. Is not treated at a treatment plant before being discharged to surface water . Pollutants picked up by runoff as it travels across the ground Why Do We Have Stormwater Permits?

Potential Stormwater Impacts: . Increased mortality for fish . Reduction in available recreational water uses . Contamination of drinking water sources . Increased need for remediation and habitat restoration . Pollution leads to stricter regulations for new development and retrofitting of existing facilities What Does The Permit Require?

. Records:

. Preparation and maintenance of a Stormwater Pollution Control Plan (SWPCP) . Reporting and site inspections . Reports to address benchmark exceedances (Tier I Reports) . Stormwater sampling and analysis . Implementation of Best Management Practices (BMPs) . Spill response procedures and cleanup Records . SWPCP

. Site specific plan drafted by a third party . Contents: Site map, BMPs, inspection forms, permit, training . Reporting

. Annual report to DEQ . Inspections

. Performed monthly and are site specific . Tier I Reports

. Must be completed within 30 days of receiving exceedance results Stormwater Sampling

. Sample discharge point 4x per stormwater year (July 1 – June 30)

. 2x prior to December 31 & 2x after . Samples must be 14 days apart . Collect within 12 hours of start of discharge . Obtain “representative” samples . During regular business hours only What Is Regulated In Stormwater?

. Total Suspended Solids (TSS) . Total Copper . Total Lead . Total Zinc . Oil & Grease . pH Oregon Benchmarks

PARAMETER BENCHMARK . TSS 100 mg/L . Total Copper 0.020 mg/L . Total Lead 0.015 mg/L . Total Zinc 0.090 mg/L . Oil & Grease 10 mg/L

. pH 5.5 – 9.0

1 mg/L = 1 part per million Contamination Sources . Zinc – sediment, galvanized metals (fences, roofs), tires, brake pad dust metal storage containers, oil, hydraulic fluid . Copper – sediment, dust from brake wear . Lead - sediment . Oils and Grease – operating equipment, spills . TSS – sediment, dust, tire wear, dirt, sanding, metal grinding . pH – Cleaning products, bleach, cedar wood, detergents Zinc Sources Sediment - TSS – Metals Sources Oil & Grease Sources Best Management Practices

Best Management Practices (BMPs): Schedule of activities, prohibitions of practices, maintenance procedures, and other physical, structural and/or managerial practices to prevent or reduce pollution of stormwater Types Of BMPs

. Good housekeeping . Preventive maintenance . Structural . Treatment . Administrative Good Housekeeping

. Sweep paved surfaces with vacuum sweeper regularly . Identify and control all on-site sources of dust . Keep dumpsters covered Preventative Maintenance

. Clean catch basins regularly . Inspect for leaks and maintain equipment monthly . Immediately clean spills and leaks . Replace wattles & catch basin inserts frequently Structural BMPs

. Minimize exposure to rain, snow, and runoff . Use grading, berms, or curbs to prevent run-on to areas where pollutants may enter stormwater . Perform all operations inside or under cover to prevent run-on, runoff, and discharges Treatment BMPs

. Detention or retention basins or vaults . Oil-water separators . Infiltration basins or trenches . Bio-filtration swales . Sand filters . Wattles . Catch basin inserts fitted with treatment media Administrative BMPs

F.3 Sampling Methods and Handling Procedures

The person collecting samples will use the following procedures to collect stormwater:

1. Powder free gloves will be worn while sampling. Use a new pair of gloves for each separate sampling location if more than one location is being sampled.

2. A grab sample will be obtained by filling a single sample “grabbed” by filling up a container either by hand or with a sampling device. As an alternative, a

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 F-2

clean, extra sample bottle can be used to dip and transfer water from the flow to the sample container.

3. Grab samples will be collected with the stormwater entering directly into bottles supplied by the laboratory, ensuring that any preservative acid in the bottle is not washed out. Samples will be collected as close to the central part of the flow as possible.

4. When holding the sample bottle, hands and other objects will be kept away from the opening to prevent contaminating the sample.

5. Bottles will not be rinsed or overfilled. Approximately 1/2 inch of headspace will be in the top of each bottle.

6. Sampling for pH will be by measuring the pH directly in the flow, or analyzing the sample within 15 minutes of sample collection.

a. Sampling technician will properly calibrated pH meter before sampling and maintain records of calibration for submittal with reporting documentation.

b. Sampling technician will follow manufacturers’ specifications and keep meter in good working order.

c. pH paper may not be used for determining the precise parameters established in this permit.

7. As needed, dissolved metals will be field-filtered with a hand held or battery- operated apparatus and 0.45 micron filter.

8. Once the sample is collected, the bottle will be capped and labeled. Labels provided by the laboratory typically included the following information: − Sample Number, or Discharge Point Name − Testing Parameter − Sample Date and Time − Sampler’s Initials − Project Number or Identifier

F.4 Sample Handling and Transfer

Original Chain-of-Custody forms will be sent to the laboratory along with the samples. A copy of all sampling forms, including field logs will be kept in the facility file. The Chain-of-Custody forms include:

MSS_SWPCP2018 Rev. 4, 11/14/2018 RSI-001-002 F-3

• Sample date and times • Sampler’s signature and time of shipment • A list of analyses to be completed • Medium sampled (water) • Number of sampling jars

Sample jars will be carefully packed in an insulated cooler and generously covered with ice or blue ice. Collected environmental samples must be stored in a field cooler with ice (or ice packs) before and during shipment to the laboratory. Samples will be iced as they are collected or immediately thereafter. Additional ice may need to be added just before shipping. Before shipping the sample cooler will be sealed with custody seals. The cooler will be shipped within 24 hours of sample collection so the lab can conduct the analyses within required holding times.

F.5 Monitoring Variance

If the Republic is unable to collect a sample because there is no discharge from the designated outfall location(s) during the sampling period, then a monitoring variance will be requested consistent with Schedule B.3 of the permit. For each missed sample, Republic/Metro will report in the quarterly DMRs due February 15 and August 15 that no discharge occurred and provide supporting data and analysis at the time of DMR submission demonstrating why the monitoring did not occur.

Supporting data may include:

• State or federal authorities declare the year a drought year.

• Rainfall in the area where the facility is located is demonstrated to be 20 percent or more below the three-year average rainfall for the area.

• Photo documentation, rain gauge data, detention basin storage volumes, storm infiltration rate or retention capacity.

Written requests for sampling variances must be submitted to DEQ by July 31 of the monitoring year in which the missed sampling occurred.

EXECUTIVE SUMMARY

If a spill has occurred, go to Appendix A. Spill Response Procedures.

More than 1,320 gallons of new and used oil product are kept in aboveground storage tanks (with holding capacities of 55 gallons or more) at the Metro South Station (facility), operated by Republic Services, Inc. in Oregon City, Oregon (site). As such, the site is subject to the requirements set forth by the Oil Pollution Prevention regulation of the Clean Water Act, which requires specific non- transportation-related facilities to develop and implement a spill prevention, control, and countermeasures plan. The SPCC plan does not need to be submitted to the U.S. Environmental Protection Agency unless requested; however, a copy of the up-to-date SPCC plan must be available on site during normal business hours.

This SPCC plan was prepared to satisfy applicable requirements of Title 40 Code of Federal Regulations, Part 112. The goal of this regulation is to prevent the spill and discharge of oil products into navigable waters (e. g., streams, creeks, rivers, and lakes) of the United States and their adjoining shorelines. The SPCC plan also addresses the spill response procedures and actions that must be implemented if a spill occurs at the facility.

Republic Services, Inc. must annually train appropriate staff as described in this plan. Training must include spill prevention; potential spill situations involving tanks, piping, material transfers, and vehicle collisions; and spill/emergency response regulations and activities applicable to the facility. Training records should be kept with this plan.

The SPCC regulation requires periodic equipment and facility inspections and documentation of the inspections. Tanks, pumps, piping, and containment structures must be regularly inspected, and inspection records should be kept with this plan.

This document includes the emergency procedures that Republic Services, Inc. should follow from the time a release/spill is discovered to its containment and cleanup. Post-cleanup activities, including internal and external reporting procedures, are described and can be used by Republic Services, Inc. as a guide.

This SPCC plan will be reviewed and evaluated at least once every 5 years. Technical amendments to the plan must be reviewed and certified by a professional engineer. Amendments to the plan will be implemented as soon as possible, but no later than 6 months following preparation of the amendment.

1.0 GENERAL INFORMATION 1.1 Purpose of the Spill Prevention, Control, and Countermeasures Plan

The purpose of this spill prevention, control, and countermeasures (SPCC) plan is to establish procedures that will prevent discharge of oil and hazardous substances in quantities that violate applicable water quality standards, cause a sheen upon or discoloration of the surface of navigable U.S. waters or adjoining shorelines, or cause a sludge or emulsion to be deposited beneath the surface of the water or upon adjoining shorelines. The SPCC plan also establishes measures that will be taken to mitigate such discharges should they occur.

This SPCC plan has been prepared for Republic Services Transfer Services of Oregon, LLC (RSI), the operating contractor of the Metro South Station (MSS) facility, pursuant to Title 40 Code of Federal Regulations (CFR), Part 112 (40 CFR 112). A copy of the current 40 CFR 112 regulations is presented in Appendix B. A complete copy of the SPCC plan will be maintained at the facility. Upon request, the plan will be made available to the U.S. Environmental Protection Agency’s (EPA’s) Regional Administrator and agents for onsite review during normal business hours.

Employees responsible for operations and maintenance of the facility are required to familiarize themselves with the contents of the SPCC plan, and a SPCC Coordinator will be responsible for implementing emergency spill response procedures (Appendix A). A second full-time employee will be trained to assume the SPCC Coordinator’s responsibilities in the Coordinator’s absence.

This plan will be reviewed at least once every 5 years from the date of institution and must be amended whenever there is a change in facility design or construction, operation, or maintenance that affects the facility’s potential to discharge oil into navigable waters. This plan must be recertified by a registered professional engineer whenever revised.

1.2 Conformance with Applicable Requirements This SPCC plan has been prepared in accordance with 40 CFR 112 and good engineering practices. In conformance with all applicable requirements of 40 CFR 112, no deviations are employed or claimed in this SPCC plan, unless noted in Section 1. 4 “Equivalent Environmental Protection.”

By implementing and maintaining this SPCC plan, the facility will be in compliance with all applicable requirements set forth in 40 CFR 112. In accordance with 40 CFR 112.7, Table 1 presents a cross- reference of the elements of this plan with applicable requirements set forth in 40 CFR 112.

1.3 Applicable State Rules and Regulations No other oil spill prevention, control, or reporting standards are required by the State of Oregon.

SPCC Plan 1600012.010 Metro South Station 1-1 February 28, 2018 Landau Associates

1.4 Equivalent Environmental Protection In accordance with 40 CFR 112.7(a)(2), a facility may deviate from certain aspects of the SPCC regulation if equivalent environmental protection is achieved through other means of spill prevention, control, or countermeasures. For this facility, equivalent environmental protections include the following.

 Portable tanks and drums (non-anchored aboveground storage tanks [ASTs]) are considered exempt from the integrity testing requirements set forth in 40 CFR 112.8(c)(6). The tanks can be lifted to visually inspect their exteriors for evidence of deterioration; if deterioration is observed, the tanks can be removed and disposed of off site. Facility personnel who use the tanks daily may note signs of deterioration prior to the monthly or annual tank inspections. In addition, all portable tanks at the site are located on the asphalt pavement or inside the building on a concrete floor or pad, which functions as a release prevention barrier.  For all tanks at the facility not equipped with level gauges, the liquid level in the tank is visually observed through the fill port to determine available capacity. This approach provides equivalent environmental protection to the overfill protection requirements set forth in 40 CFR 112.8(c)(8).  The ASTs will be inspected monthly in lieu of routine integrity testing. During monthly inspections, the outside surfaces, particularly the tank bottoms, will be inspected for corrosion and signs of leakage. For double-walled tanks, the interstitial space will be inspected for the presence of oil, an indicator of inner tank leakage.

2.0 FACILITY INFORMATION 2.1 Site Location The MSS facility (facility) is located at 2001 Washington Street in Oregon City, Oregon (site). Figure 1 shows the general location of the facility.

2.2 Site History and Current Operations The facility is a regional solid waste and recycling center that was established in April 1983andis open to the general public 7 days a week, year-round (except on New Year’s Day, Thanksgiving, and Christmas). The facility is open from 7:00 a.m. to 7:00 p.m. March through September, and from 7:00 a.m. to 6:00 p.m. October through February. Commercial customers can use an automated gate to access the site before 7:00 a.m.

Metro owns the site and facilities and is responsible for staffing and operating the household hazardous waste facility (HHWF) and the scale houses. Metro contracts with RSI to process and recycle solid waste at the transfer station. The operating contractor, RSI, is responsible for meeting discharge permit requirements and is required to maintain the facility and its equipment.

Metro has worked to improve the safety and efficiency of the region’s solid waste handling by making several additions to the facility. The facility encompasses three buildings, with a total area of more than 80,000 square feet, where waste is received and processed; a 5,000-square-foot maintenance building; and three scale houses.

The site receives and processes solid waste and recyclable material from commercial and residential sources. The site has two processing buildings, where solid waste and recyclable material are unloaded for processing indoors, undercover. The main processing building has two processing areas, Bay 1 and Bay 2, separated by a disposal pit (referred to as the “pit”). Bay 1 is used primarily to process the waste produced by commercial customers, which includes no recoverable material; commercial customers tip their loads directly into the pit for transfer to the landfill. Bay 2 is used to process drier waste loads from which recyclable items are sorted; leftover waste is placed in the pit. The other processing building is a large, open area with two bays, Bays 3/4. Bay 3 is used primarily to sort dry waste for recoverable material. Bay 4 is used to receive and process residential organics. Bay 3 has a conveyor set-up to improve sorting efficiency; non-recyclable material is loaded into a container and taken to Bay 1 for disposal in the pit. Loads containing only wood and yard waste are deposited into Bay 4.

Wet waste and other materials that have no recoverable value are reloaded into sealed trailers and transferred to a landfill. Dry waste is sorted to extract materials that have recoverable value. Recovered materials typically are loaded into open-top containers and shipped to markets. Trailers of

SPCC Plan 1600012.010 Metro South Station 2-1 February 28, 2018 Landau Associates waste and containers of recycled materials are stored outside on pavement until shipment. Shipments are sent off site Monday through Saturday.

The site also receives and processes federally exempt hazardous waste from households and conditionally exempt generators at the HHWF, located at the main entrance. Waste types include acids, bases, cleaners, solvents, pesticides, herbicides, poisons, petroleum products, and paints. Hazardous materials are shipped from the site at least once a week. Some reusable materials (such as household cleaners) are stored on site to be given away.

The main HHWF building has a room on its west side referred to as the tunnel. The tunnel provides storage for materials used in the HHWF, including personal protective equipment, facility supplies, waste oils and antifreeze, and reusable products. Floor drains in this room flow to a pump station that can be shut off to prevent a release to the sanitary sewer.

The HHWF is open from 9:00 a.m. to 4:00 p.m., Monday through Saturday, and is closed on Sunday. Materials received at the HHWF are processed and shipped to recovery, disposal, and/or treatment facilities, consistent with hazardous waste regulations. Loading and unloading at this facility is done under canopy. The concrete receiving and shipping floors are sloped to drain to blind sumps in case of accidental spill. All materials are processed inside the building or under the cover of the receiving canopy. The inside of the building was constructed with floor pits to contain spills and fire water. The area under the receiving canopy was constructed to divert accidental spills to a containment sump for isolation and cleanup.

Metro staff uses the three scale houses on site to weigh materials delivered to the facility, collect user fees, and record transaction information. Truck scales are located beside each scale house.

A dedicated maintenance building, 5,000-square-feet in area, is located at the northeast end of the site, and a covered area near the maintenance building is used to process appliances for recycling.

A three-sided truck wash building is used by commercial solid waste customers for vehicle wash down. The concrete and paving at this wash area slope toward a collection trench that is connected to the oil-water separator and the sanitary sewer system. The oil-water separator is cleaned regularly.

There are no stormwater drains in the processing areas of these buildings. Roof drains direct stormwater to the pavement, where it flows to a catch basin; some drains are piped to a nearby stormwater catch basin. Vehicles using the buildings might track material on their tires, which could contaminate stormwater.

Within the last 3 years, there have been no reports of significant releases of petroleum products at the site.

2.3 Material Storage The following oil products stored (in tanks and drums) and used at the facility are regulated under provisions of 40 CFR 112.

 Diesel fuel used to fuel facility vehicles and heavy equipment.  Lubricating fluids (motor oil, gear oil, etc.) used in facility vehicles and heavy equipment and machinery.  Hydraulic fluids (hydraulic oil, transmission fluid, brake fluid, etc.) used in facility vehicles, heavy equipment, and machinery.  Used motor oils, hydraulic oils, and antifreeze stored on site prior to collection for disposal or recycling. These oils are dropped off by customers and generated from internal maintenance activities.  A bio/microorganism parts washer and degreaser, serviced by a third-party contractor.  Antifreeze used for servicing facility vehicles.  Used vegetable and linseed oils dropped off by customers and stored on site prior to collection for disposal or recycling.

2.3.1 Aboveground Storage Tanks and Drums Thirteen (13) ASTs are located on site, as shown on Figure 2. A description of the tanks and associated spill containment and countermeasures can be found in Table 2.

A dual-walled steel tank located just outside the entrance to Bay 2, in the main processing building stores up to 2,000 gallons of diesel used to fuel facility vehicles and heavy machinery. The tank is protected by bollards to limit vehicles or equipment from running into it.

Two 1,200-gallon hydraulic oil tanks are stored on a large spill containment pad, located within the hydraulic power unit room next to the covered municipal solid waste (MSW) pit and underneath the main building.

Two 500-gallon steel tanks in the Bay 2 Hazardous Area are used to collect and store used oil and antifreeze. Small containers and drums of used oil and antifreeze are dropped off by customers and stored on secondary containment pallets until Metro employees can empty them into the storage tanks.

Three 260-gallon, single-wall tanks are installed within a metal containment inside the maintenance building and used to store the motor and hydraulic oil used on facility equipment and vehicles, along with waste oil. A 350-gallon tank, fabricated with an open top and built-in spill containment, stores additional waste oil used to fuel the furnace inside the maintenance building. Small amounts (< 55 gallons) of additional hydraulic oil, motor oil, and antifreeze are stored in drums or small containers, on top of secondary containment pallets inside the maintenance building.

SPCC Plan 1600012.010 Metro South Station 2-3 February 28, 2018 Landau Associates

Four 55-gallon tanks used for collection of waste oil, antifreeze, vegetable oil, and linseed oil are located under cover in the HWWF. The tanks are stored on top of secondary containment trays, and the vegetable and linseed oil tanks are stored in the flammable bay, which has additional spill containment volume due to the concrete sumps that drain to the sanitary sewer.

2.3.4 Facility Response Plan The facility does not meet the substantial harm criteria, and as such, does not require a facility response plan. See Appendix C for the substantial harm criteria certification.

2.4 Security Site access is restricted by fencing and building access. Site buildings and gates are locked when the site is unoccupied.

All tanks with master flow and drain valves are located inside locked buildings or in a fenced yard. Tank valves are locked to prevent unauthorized access.

The starter control for all oil pumps is accessible only to authorized personnel, and the area in which the control is located is locked when the site is unoccupied.

SPCC regulations require the facility to maintain adequate lighting—commensurate with the facility type and location—to prevent acts of vandalism and assist in the discovery of oil discharges. The facility’s lighting meets these regulations. A pole-mounted light illuminates the entrances of the

SPCC Plan 1600012.010 Metro South Station 2-6 February 28, 2018 Landau Associates facility and diesel fueling station area. Each building at the facility is equipped with outdoor lighting that illuminates entrances, the area surrounding the building, and the used oil tank area. The lighting is sufficient to detect spills and deter vandalism.

SPCC Plan 1600012.010 Metro South Station 2-7 February 28, 2018 Landau Associates

3.0 FACILITY DRAINAGE AND STORMWATER MANAGEMENT 3.1 Sanitary Sewer Discharge Sanitary sewer discharge at the facility is covered under Industrial Wastewater Discharge Permit # 02T-004-0, provided by Tri-City Service District (Oregon City, Oregon). Floor drains in the tunnel room within the HHWF can be shut off to prevent discharge to the sanitary sewer.

3.1.1 Truck Wash Station The truck wash was designed with a floor that slopes to the sanitary sewer. Trucks back in and rinse out their trash containers. Residual trash is picked up and placed in bins within the wash area. Rinse water flows to a catch basin spill control separator for disposal to the sanitary sewer system.

3.2 Surface Drainage Stormwater is discharged from a large stormwater detention/wetland pond on site to the local municipal storm system via a 48-inch culvert pipe. The municipal system includes open ditch and drainage pipe conveyances to Clackamas Cove, which drains to the Clackamas River.

There are five inlets to the detention/wetland pond. Two of these are from the stormwater area (Outfall #5 – west drainage area. One inlet is from the stormwater collected at curb inlets along Washington Street. The other two inlets are from the ditches described below. Outfall #6 is the culvert that drains the pond.

The facility has one outfall to the ditch on the property line with the railroad to the north (Outfall #1 – northeast drainage area). Stormwater from the northeastern portion of the site discharges into the open, vegetated ditch at Outfall #1. An oil separator is located upstream of Outfall #1.

The facility also has two outfalls to the ditch along Washington Street to the south (Outfall #2 – truck wash area, and Outfall #3 – southeast drainage area). Stormwater in the southeastern area, Outfall #3, is collected from portions of the roofs on Bay 3/4 and the main building, the pavement and permeable brick areas east of Bay 1, the landscape areas surrounding the access road, and the access road. The majority of drainage in the southeastern area is captured in a pump station that acts as an oil separator. The pump station transfers the stormwater to a trapped catch basin upstream of Outfall #3. The area to the east of the main building enters the same trapped catch basin upstream of Outfall #3. The truck wash area, Outfall #2, has a 10-foot by 60-foot area of pavement in front (west) of the truck wash that drains to the sanitary sewer; the roof and other pavement drain to the stormwater system along with a small area of landscaping. An oil separator is located upstream of Outfall #2. Both separators are inspected and cleaned regularly.

The north and south ditches have run-on from adjacent property, and drain to the facility’s detention/wetland pond. Both ditches are vegetated and act as bioswales. A compost filter is

SPCC Plan 1600012.010 Metro South Station 3-1 February 28, 2018 Landau Associates maintained at the west end of the south ditch (Washington Street), near the facility’s main entrance, Outfall #7. The compost filters and bioswales are maintained as needed to remove sediment, accumulated trash, and debris on the compost bed and in the swale. Good vegetation also is maintained in the swale.

Stormwater runoff from a portion of the Bay 1 roof flows into a French drain, which daylights at the Washington Street ditch. During heavy rains, water seeps into the ditch from the daylight end of the French drain. The French drain is inspected and maintained as needed to remove any accumulated sediment.

3.2.1 Run-on and Non-Stormwater The site receives run-on from upgradient property and adjacent local streets. Stormwater from Highway 213 and Washington Street is collected and piped directly to the detention/wetland pond. Run-on into the ditch between the facility and railroad (north ditch), upstream of Outfall #1, is from the railroad bed and railroad, the MSS facility, and State of Oregon landscaped areas. Oregon City’s property (formerly a log deck) north of the railroad also releases run-on into the north ditch, located downgradient of Outfall #1, just before the detention/wetland pond.

Groundwater is collected from footings, foundations, and pavement sub-drains to maintain integrity of structures. Groundwater collected from the main building is commingled with waste water collected from the compactors and discharged via the sanitary sewer. Groundwater collected from Bay 3/4 and the maintenance building is commingled with stormwater and discharged via Outfall #1 or Outfall #3.

3.3 Stormwater Management Stormwater management is performed in accordance with the existing Stormwater Pollution Control Plan for the facility, updated in December 2017. Based on its current operations and applicable standard industrial classification (SIC) codes, the facility holds an active National Pollutant Discharge Elimination System (NPDES) 1200-Z Industrial Stormwater Discharge Permit, issued by the Oregon Department of Environmental Quality. The following sections describe the outside fuel stations and oil storage at the site. As part of the NPDES 1200-Z permit requirements, samples are collected from identified site outfalls and analyzed in accordance with the permit requirements.

3.3.1 Fueling Stations The diesel fueling station is located east of the main transfer building. The fuel storage tank has a steel, dual-walled secondary containment area with 110 percent of the total storage capacity of the tank. The fueling station is protected from vehicular traffic by concrete barriers and yellow-painted bollards.

SPCC Plan 1600012.010 Metro South Station 3-2 February 28, 2018 Landau Associates

3.3.2 Liquids Storage Two 55-gallon steel drums (A-9 and A-10) are staged on a containment pallet at the HHWF driveway and used to collect and store used oil and antifreeze. These drums are moved to the tunnel when full and mobilized off site for daily disposal.

All other oil storage tanks are located inside facility buildings and protected from precipitation in compliance with the requirements of the NPDES 1200-Z Stormwater Permit.

4.0 PERSONNEL TRAINING 4.1 Spill Prevention and Response Training Under 40 CFR 112.7(f), owners or operators are responsible for instructing personnel on spill prevention and abatement procedures. A designated person who reports to management must administer training. Owners and operators are responsible for conducting spill prevention training at intervals frequent enough to ensure complete understanding of the facility’s SPCC plan. The following guidelines will be adhered to when administering the training program for the facility.

4.1.1 Training for Permanent Personnel  Prevention and Safe Work Practices. Appropriate facility personnel will participate in annual training to facilitate site operation and maintenance and prevent the discharge of harmful quantities of oil or hazardous substances. This training will include familiarization with the safety data sheets (SDS) appropriate to the job assignment; safe work practices; and emergency response procedures, equipment, and systems.  Spill Response and Emergency Procedures. Appropriate facility personnel will be trained annually in spill and emergency response procedures. This training will include information regarding spill abatement and containment, spill cleanup, disposal of spill materials, and emergency communications.  Reporting and Regulations. Facility personnel will be apprised annually of their responsibilities for ensuring compliance with spill incident reporting and emergency response regulations applicable to the facility. Trainers must be aware of new regulations issued by local and federal agencies and should update the training program accordingly. New personnel will be trained within 2 weeks of entering the facility.

4.1.2 Training for Transient Personnel When necessary, transient personnel will be advised of applicable spill prevention measures upon entering the facility. Transient personnel and drivers of vehicles not regularly employed at the facility will be advised, when necessary, of the presence of aboveground and below-ground pipes, tanks, and other potential spill sources.

4.1.3 Tank Truck Drivers Tank truck drivers loading or unloading materials at the facility will adhere to the following guidelines.

 Remain with the vehicle while loading/unloading.  Drain the loading/unloading lines to the storage tank; close the drain valves before disconnecting the lines; and make sure a drain pan or other appropriate containment device is located under all connections.  Inspect the vehicle before departure to be sure loading/unloading lines have been disconnected and drain and vent valves are closed.  Immediately report any leaks or spills, including quantity, to the SPCC Coordinator.

SPCC Plan 1600012.010 Metro South Station 4-2 February 28, 2018 Landau Associates

5.0 SPILL PREVENTION MEASURES 5.1 General An effective response to an oil-release incident includes keeping released material separate from water. This will minimize migration and the potential for human and environmental exposure. Every effort should be made to prevent spills and emphasize substance containment at the source rather than to rely on spill cleanup.

5.2 Spill Prevention and Safe Work Practices Accidental discharge of oil at the facility is most likely to occur via one of three scenarios: (i) equipment or operator failure during onsite activities, (ii) equipment or operator failure during fueling, or (iii) structural failure of an AST. This section includes a description of shop practices and tank design standards employed to prevent accidental discharge.

5.2.1 Handling Used Motor Oil The following equipment and procedures are used to prevent accidental spilling of used oil, during transfer to/from the used-oil holding tank. Equipment and supplies are to be made available through the SPCC Coordinator or her designee.

5.2.1.1 Facility and Supplies  Multiple ASTs used to store used oil. See Table 2.  A drip bucket/pan.  A shovel.  A yard brush.  A spill kit, including absorbent material, personal protective equipment, drum liners, and spill containment socks. Spill kits are located throughout the facility; see Figure 2. A full list of supplies included in the spill kits is provided in Appendix F.

5.2.1.2 Oil Transfer Procedures  Used oil must be transferred within the containment area over a spill pallet or drip pan. Technicians should never fill or drain oil containers in the open yard, as materials spilled in the yard can easily enter the stormwater collection system.  The technician must remain in the containment area during oil transfer.  The technician must not overfill the receptacle tanks.  A licensed used-oil disposal company should be contacted to empty the used-oil tank when full.  Used oil cannot be stored temporarily in open-drip pans or used tanks without secondary containment.

SPCC Plan 1600012.010 Metro South Station 5-1 February 28, 2018 Landau Associates

 If a spill of less than 25 gallons occurs outside the containment area, the technician must place an absorbent on the spilled fuel immediately. As soon as the absorbent becomes saturated with spilled material, the technician should use a sweeping brush and shovel to collect the absorbent and place it in a covered receptacle marked for used absorbents. The used absorbent container must be protected from rain at all times.  Used absorbents must be disposed of in accordance with RSI’s policy for disposal of special waste.  Clean absorbents must be stored in a location readily accessible during emergencies. Any absorbent taken from spill kits must be replaced with a clean absorbent.  The shovel, yard brush, and drip bucket/pan must be replaced following use.  If a spill of 25 gallons or more occurs outside the containment area, take immediate steps to contain the spill. Call for assistance if necessary, and make sure the incident is reported to the SPCC Coordinator.  When not in use, master flow and drain valves permitting direct discharge from ASTs will be locked in the closed position.  Filling and draining connections of oil conduits should be capped or blank-flanged when out of service for extended periods.  The containment area must remain free of debris and waste material other than oil.

5.2.2 Fuel Transfer Procedures The 2,000-gallon AST supplies diesel fuel to waste hauling trucks and other facility equipment. The equipment and procedures listed in this section will be used to prevent accidental discharge and spills. Supplies listed in this section are available through the SPCC Coordinator or Maintenance Manager.

5.2.2.1 Facility and Supplies  The diesel storage tank is a dual-walled, steel tank located on an asphalt-paved surface just outside the entrance to Bay 2. The secondary containment is sealed from rain water, and has a capacity of 110 percent of the tank’s total storage capacity.  A spill kit is located at the fueling station area adjacent to the tank and contains absorbent material, a salvage drum, plastic sheeting, and spill containment socks.  Only facility vehicles refuel at the facility. Vehicles fuel on the asphalt surface to the north side of the tank.  A shovel is available for distributing absorbent and containment materials and for cleanup.  A yard brush is available for cleanup and containment management.  Dispensing hoses are fitted with a breakaway coupling, which allows the hose to detach from the dispenser safely, in the event the vehicle is driven away with the nozzle still in its fuel tank.  Fueling trucks are equipped with breakaway coupling on the dispensing hoses.

SPCC Plan 1600012.010 Metro South Station 5-2 February 28, 2018 Landau Associates

 The facility spill kit is marked and stored in a highly visible location (Figure 2). The kit can be relocated readily with a forklift and transported to the spill location. The contents of the spill kit are listed in Appendix F.

5.2.2.2 Operating Procedures  Fueling must be conducted on a paved surface.  The vehicle ignition must be turned off during fueling.  Before the fueling transfer process, the fuel supplier or fueler will verify that the transfer hoses are securely attached, and the hose couplings are latched.  The fueler must remain with the vehicle while fueling.  The fuel supplier or fueler must make a visual assessment of the liquid level in the receiving tanks. When the tanks are filled, the supplier or fueler must shut off the flow to limit the potential of overfilling the tank.  The fueler must not overfill the tank.  The fueler must not keep the nozzle open using a device or method other than his hand.  Onsite personnel must be present at the fueling station during fueling operations.  After the unloading process is completed, the fuel supplier will drain the hose into the tanks (or, if necessary, into a portable container).  The fill port on the tanks will be secured.  The fuel supplier will prepare the tank truck for departure. The fuel supplier will check for any drips or leaks under the tank truck. If any are observed, the fuel supplier will take corrective actions to stop the drips or leaks. Prior to signing the supplier manifest and allowing the supplier to leave the site, the SPCC-trained facility representative will inspect the unloading area for any oil drips or spills that occurred during the unloading process. If any drips or spills occurred, the fuel supplier or SPCC-trained facility representative will clean up the spill and properly dispose of the residue. The fuel supplier will then remove the wheel chocks and leave the facility.  If a spill of less than 25 gallons occurs, no matter how small, the fuel supplier must place absorbent on the spilled fuel immediately, pick up the absorbed material with a sweeping brush and shovel, and place the material in the ‘Used Absorbent’ receptacle.  The fuel pad must be dry cleaned (sweep and shovel; absolutely no water).  The ‘Clean Absorbent’ and ‘Used Absorbent’ storage containers must be covered or otherwise protected from rain at all times.  Used absorbent must be disposed of properly.  The ‘Clean Absorbent’ container must be refilled when it has been depleted to less than half of its capacity.  At all times, spill kits must be protected from precipitation of any type.  The shovel and drip pan/bucket must be replaced at the fueling area following use.

SPCC Plan 1600012.010 Metro South Station 5-3 February 28, 2018 Landau Associates

 The drip pan/bucket must be stored upside down when not in use.  To ensure vehicles do not rupture the tank, concrete barriers and bollards should remain in place. All vehicles should remain outside this protected area and not allowed to bypass the concrete barrier or bollard.  Clean absorbent must be stored in a location readily accessible during emergencies. Any absorbent taken from spill kits must be replaced with clean absorbent. The SPCC-trained facility representative will restock any materials used during the spill response (i.e., the spill kit).  If a spill of 25 gallons or more occurs outside the containment vault, take immediate steps to contain the spill. Call for assistance, if necessary, and make sure the incident is reported to the SPCC Coordinator.

5.3 Emergency Response Action Plan 5.3.1 Spill Response Plan – Immediate Actions The person discovering a release of material from a container, tank, or operating equipment should initiate the following.

 Extinguish any sources of ignition. Until the material is identified as nonflammable and noncombustible, all potential sources of ignition in the area should be removed or disabled. Vehicles should be turned off. If the ignition source is stationary, attempt to move spilled material away from the ignition source. Avoid sparks and movement likely to create static electricity.  Ensure that no danger to human health exists. If there is an immediate threat to human life (e.g., a fire in progress or fumes overcoming workers), an alarm should be sounded to evacuate the building, and the fire department should be called. If there is no health or safety hazard, begin to address the spill.  Attempt to stop the release at its source. The discoverer may attempt to complete simple procedures (i.e., turning valves, plugging leaks, etc.). All other efforts to control leaks should be supervised by the SPCC Coordinator or Assistant SPCC Coordinator.  Contain the material released into the environment. Following proper safety procedures, contain the spill by placing absorbent materials and dikes using shovels and brooms. A mobile spill kit that includes adsorbent material, containment socks, rags, plastic, and a salvage drum is located in the facility. Consult the applicable SDS for material compatibility, safety, and environmental precautions. Spill kits are located at various locations throughout the facility (Figure 2).  Initiate spill notification and reporting procedures. Report the incident immediately to the Maintenance Supervisor or the SPCC Coordinator. Request the assistance of the local fire department’s hazardous materials response team if an uncontrollable spill has occurred and/or if the spill has migrated beyond the site boundaries. A summary of emergency personnel and duties is provided in Appendix G.  Consult the SDS. If material is released outside the containment areas, it is critical that the material is accurately identified and appropriate control measures are taken in the safest

SPCC Plan 1600012.010 Metro South Station 5-4 February 28, 2018 Landau Associates

possible manner. Consult the SDS for accidental release measures for petroleum products used at the facility.  Consult local response agencies. In the following instances, consult local response agencies. If the source of the release has not been found, if special protective equipment is necessary to approach the release area, or if assistance is required to stop the release, notify Clackamas Fire District #1 by calling 911. Unless the site is deemed unsafe by emergency response agencies, RSI personnel must remain available to guide the fire department or the response team’s efforts.

5.3.2 Spill Cleanup and Disposal Procedures Appropriate personal protective equipment and cleanup procedures for the materials on site can be found in the SDS. When cleaning up spills, care must be taken to minimize waste generation. The Operations Manager must be made aware of all spill cleanups and can provide assistance for the issues discussed below.

 Recover or cleanup the material spilled. As much spilled material as possible should be recovered and reused where appropriate. Material that cannot be reused must be declared waste. Saturated solids will be shoveled into open-top, 55-gallon drums. When drums are filled after a cleanup, secure their lids and label (or relabel) to identify the substance contained, the date of the spill/cleanup, and the facility and location. Combining non- compatible materials can cause dangerous chemical and/or physical reactions or severely limit disposal options. Compatibility information can be found in the SDS.  Cleanup of the spill area. Surfaces contaminated by the release will be cleaned with an appropriate substance. Cleanup agents must be minimized, contained, and properly disposed of. Occasionally, porous materials, such as wood, soil, or oil-dry, may be contaminated. These materials will require special handling for disposal.  Decontaminate tools and equipment used in cleanup. Even if dedicated to cleanup efforts, used tools and equipment must be replaced or decontaminated before they are restored to the spill kit.

5.3.3 Post-Cleanup Procedures  Initiate notification and reports to outside agencies. The SPCC Coordinator will determine if a reportable spill has occurred. Verbal notifications to government agencies and emergency planning committees will be made, if necessary. Where verbal notification is given, a confirming written report will be sent to the same entity, per Section 6.0 of this plan. A reportable spill includes any amount of oil released to the waters of the state; oil spills on land in excess of 42 gallons; hazardous materials that are equal to, or greater than, the quantity listed in 40 CFR, Part 302 (List of Hazardous Substances and Reportable Quantities), and amendments adopted before July 1, 2002.  Arrange for proper disposal of any waste materials. The waste material from the cleanup must be characterized using RSI’s Special Waste Manual. Representative sampling and analysis may be necessary to make characterizations. In any case, the SPCC Coordinator will assure that the waste is transported and disposed of in compliance with applicable laws and

SPCC Plan 1600012.010 Metro South Station 5-5 February 28, 2018 Landau Associates

regulations. When manifests are needed, the SPCC Coordinator will see that they are prepared and, when appropriate, returned in the time allotted by the disposal site.  Review the spill plans. Management and operating personnel will evaluate spill response efforts, notification procedures, and the cleanup equipment used (Appendices A, F, and G). Where deficiencies are found, the plan will be revised and amended.

5.3.4 Communications In case of a fire, spill, or other emergency, paging systems and two-way radios can be used to contact personnel. Telephones are located in the facility offices.

5.3.5 Spill, Fire, and Safety Equipment Portable fire extinguishers located throughout the facility are well marked and easily accessible. Records are kept on fire equipment in service, and regular testing is performed in accordance with established good practices. A recommended list of fire extinguishers and spill and safety equipment is included in Appendix F.

5.3.6 Liaison with Local Authorities Copies of this plan will be submitted to the local fire department, police department, and hospital, if requested. In addition, familiarization sessions will be held with personnel from these organizations, as they deem necessary. Personnel responding to an emergency must be familiar with the fuels and chemicals used at the facility; the possibility for release of hazardous materials; and the location of fire equipment, such as hydrants and extinguishers.

SPCC Plan 1600012.010 Metro South Station 5-6 February 28, 2018 Landau Associates

7.0 FACILITY INSPECTION 7.1 General In accordance with 40 CFR 112.7(e)(8), the owner and operator will inspect the facility for malfunctions, deterioration, operator errors, and discharge that may cause—or be causing—spills of oil and hazardous substances. The inspection will be conducted often enough to identify problems in time to correct them before a spill occurs. Inspections of tanks, secondary containment, and response equipment are to be documented, and records should be maintained by the SPCC Coordinator.

7.2 Monthly Inspection The following inspections will be conducted either monthly or with more frequency, if deemed appropriate. Observations made during inspection should be recorded on the monthly inspection form found in Appendix I. The SPCC Coordinator will be notified and the appropriate action initiated if a problem is detected during the inspection.

7.2.1 Aboveground Storage Tanks The condition of ASTs, including drums, containing oil or hazardous substances will be examined visually, and the need for maintenance will be determined. Examination will include aboveground foundation and tank structural supports. The outside of the tanks will be checked for signs of deterioration, leaks from seams, rivets, bolts, and gaskets and for accumulation of oil or hazardous substances inside containment structures.

Per the Standard for Inspection of Aboveground Storage Tanks (Steel Tank Institute, the STI SP001),1 all ASTs should be inspected monthly and annually, with the more comprehensive annual inspection serving as an environmental equivalent measure to periodic integrity testing. The facility will conduct monthly inspections under the guidelines outlined above and in accordance with additional criteria, similar to the more comprehensive annual inspection defined in STI SP001. During monthly inspections, outside surfaces, particularly the tank bottoms, will be inspected for corrosion and signs of leaks. AST supports and foundations will be inspected for integrity and condition. For dual-walled tanks, the AST and interstitial space will be inspected for the presence of oil, an indicator of inner tank leakage, or for water, an indicator of outer tank leakage.

7.2.2 Aboveground Piping Aboveground valves and piping will be examined for general condition of supports, flange joints, expansion joints, valve glands and bodies, and drip pans. Periodic pressure or other non-destructive integrity testing may be warranted for piping, where facility drainage could fail and lead to a spill event.

SPCC Plan 1600012.010 Metro South Station 7-1 February 28, 2018 Landau Associates

7.2.3 Containment Structures Containment walls, vaults, and berms will be inspected for accumulation of oil or hazardous substances, and the source of the oil or substances will be determined. Visual inspections will be performed to ensure the integrity of the containment walls.

7.3 Response Equipment Inspection Emergency response equipment will be inspected monthly or following a spill event. Each item listed in Appendix F should be checked for proper storage location, accessibility, operational status/condition, shelf life, and quantity. Any discrepancies should be reported to the SPCC Coordinator and corrected as soon as possible. Observations made during inspection should be recorded on the monthly inspection forms found in Appendix I.

7.4 Inspection Records Inspections will be documented, and a written record of inspection, signed by the SPCC Coordinator, will be kept on file. All inspection records should be kept for comparison and will be retained in Appendix I for a minimum of 3 years.

7.5 Integrity Testing The 13 ASTs have a continuous release detection method, a means of detecting release of a liquid through inherent design and spill control. All ASTs should be periodically inspected by an SPCC-trained facility representative in keeping with the STI SP001.

As noted in Section 7.2.1, all ASTs will be inspected monthly with additional criteria; monthly inspections will be similar to the more comprehensive annual inspection defined in STI SP001. Monthly inspections with additional criteria will serve as an environmental equivalent measure to periodic integrity testing.

APPENDIX A

Spill Response Procedures

If there is an immediate threat to human life (e.g., a fire in progress or fumes overcoming workers), make an announcement to evacuate the building and call 911.

EMERGENCY RESPONSE GOAL: During an oil- or substance-release incident, an effective response procedure includes keeping the released material separated from water. This will minimize migration and the potential for human and environmental exposure.

EMERGENCY CONTACTS:

A. SPCC COORDINATOR Amy R. Roberts 503.901.9505

B. ASSISTANT SPCC COORDINATOR Christine Baker 971.444.3230

J. CLACKAMAS COUNTY WATER ENVIRONMENT SERVICES, POLLUTANTS 503.353.4592 Discovery of a Release

The person who discovers a release of material from a container, tank, or operating equipment should immediately report the incident to the Supervisor and the SPCC Coordinator.

 Extinguish any nearby sources of ignition. Ensure that no danger to human health exists. Unless the spilled material is identified as nonflammable and noncombustible, all potential sources of ignition in the area, including vehicle engines, should be turned off, extinguished, or removed. If the ignition source is stationary, attempt to direct spilled material away from the source. Avoid sparks and movement likely to create static electricity.  Attempt to stop the release at its source. Ensure that no danger to human health exists. Simple procedures (e.g., turning valves, plugging leaks) may be attempted by the discoverer if there is a reasonable certainty of the leak’s origin. All other efforts to control leaks should be supervised by the SPCC Coordinator or Assistant SPCC Coordinator.  Initiate spill notification and reporting procedures. Request the assistance of the fire department’s hazardous materials response team if an uncontrollable spill has occurred and/or if the spill has migrated beyond the boundaries of the facility. The SPCC Coordinator will make the necessary corporate and external regulatory notifications.

Containment of a Release

Material released outside the containment area must be accurately identified, and appropriate control measures should be taken in the safest possible manner. Consult the safety data sheets (SDSs) kept in the facility office. To contain a release, follow these procedures:

 Attempt to stop the release at its source. If the source of the release has not been found; if special protective equipment is necessary to approach the release area; or if assistance is required to stop the release, call the fire department to halt the discharge at its source. If possible, site personnel should remain available to guide the fire department’s efforts.  Contain the material released into the environment. Following proper safety procedures, contain the spill by using shovels and brooms to place absorbent materials and dikes. A spill kit that includes absorbent material, containment socks, rags, plastic, and a salvage drum is located in the facility. Consult applicable SDSs for material compatibility, safety, and environmental precautions.  Continue the notification procedure. Inform the SPCC Coordinator of the release (the Coordinator shall make subsequent notifications as appropriate).

Spill Cleanup and Reporting

Once the spill situation is under control and the release has been contained, facility personnel should commence the cleanup and reporting procedures described in Section 6 of the main text. Retain outside contractors to clean up the spill, if necessary.

(e) This part establishes requirements for the preparation and implementation of Spill Prevention, Control, and Countermeasure (SPCC) Plans. SPCC Plans are designed to complement existing laws, regulations, rules, standards, policies, and procedures pertaining to safety standards, fire prevention, and pollution prevention rules. The purpose of an SPCC Plan is to form a comprehensive Federal/State spill prevention program that minimizes the potential for discharges. The SPCC Plan must address all relevant spill prevention, control, and countermeasures necessary at the specific facility. Compliance with this part does not in any way relieve the owner or operator of an onshore or an offshore facility from compliance with other Federal, State, or local laws.

(f) Notwithstanding paragraph (d) of this section, the Regional Administrator may require that the owner or operator of any facility subject to the jurisdiction of EPA under section 311(j) of the CWA prepare and implement an SPCC Plan, or any applicable part, to carry out the purposes of the CWA.

(1) Following a preliminary determination, the Regional Administrator must provide a written notice to the owner or operator stating the reasons why he must prepare an SPCC Plan, or applicable part. The Regional Administrator must send such notice to the owner or operator by certified mail or by personal delivery. If the owner or operator is a corporation, the Regional Administrator must also mail a copy of such notice to the registered agent, if any and if known, of the corporation in the State where the facility is located.

(2) Within 30 days of receipt of such written notice, the owner or operator may provide information and data and may consult with the Agency about the need to prepare an SPCC Plan, or applicable part.

(3) Within 30 days following the time under paragraph (b)(2) of this section within which the owner or operator may provide information and data and consult with the Agency about the need to prepare an SPCC Plan, or applicable part, the Regional Administrator must make a final determination regarding whether the owner or operator is required to prepare and implement an SPCC Plan, or applicable part. The Regional Administrator must send the final determination to the owner or operator by certified mail or by personal delivery. If the owner or operator is a corporation, the Regional Administrator must also mail a copy of the final determination to the registered agent, if any and if known, of the corporation in the State where the facility is located. (4) If the Regional Administrator makes a final determination that an SPCC Plan, or applicable part, is necessary, the owner or operator must prepare the Plan, or applicable part, within six months of that final determination and implement the Plan, or applicable part, as soon as possible, but not later than one year after the Regional Administrator has made a final determination.

(5) The owner or operator may appeal a final determination made by the Regional Administrator requiring preparation and implementation of an SPCC Plan, or applicable part, under this paragraph. The owner or operator must make the appeal to the Administrator of EPA within 30 days of receipt of the final determination under paragraph (b)(3) of this section from the Regional Administrator requiring preparation and/or implementation of an SPCC Plan, or applicable part. The owner or operator must send a complete copy of the appeal to the Regional Administrator at the time he makes the appeal to the Administrator. The appeal must contain a clear and concise statement of the issues and points of fact in the case. In the appeal, the owner or operator may also provide additional information. The additional information may be from any person. The Administrator may request additional information from the owner or operator. The Administrator must render a decision within 60 days of receiving the appeal or additional information submitted by the owner or operator and must serve the owner or operator with the decision made in the appeal in the manner described in paragraph (f)(1) of this section.

§ 112.2 Definitions.

For the purposes of this part:

Adverse weather means weather conditions that make it difficult for response equipment and personnel to clean up or remove spilled oil, and that must be considered when identifying response systems and equipment in a response plan for the applicable operating environment. Factors to consider include significant wave height as specified in appendix E to this part (as appropriate), ice conditions, temperatures, weather-related visibility, and currents within the area in which the systems or equipment is intended to function.

Alteration means any work on a container involving cutting, burning, welding, or heating operations that changes the physical dimensions or configuration of the container.

Animal fat means a non-petroleum oil, fat, or grease of animal, fish, or marine mammal origin.

Breakout tank means a container used to relieve surges in an oil pipeline system or to receive and store oil transported by a pipeline for reinjection and continued transportation by pipeline.

Bulk storage container means any container used to store oil. These containers are used for purposes including, but not limited to, the storage of oil prior to use, while being used, or prior to further distribution in commerce. Oil-filled electrical, operating, or manufacturing equipment is not a bulk storage container.

Bunkered tank means a container constructed or placed in the ground by cutting the earth and re-covering the container in a manner that breaks the surrounding natural grade, or that lies above grade, and is covered with earth, sand, gravel, asphalt, or other material. A bunkered tank is considered an aboveground storage container for purposes of this part.

Completely buried tank means any container completely below grade and covered with earth, sand, gravel, asphalt, or other material. Containers in vaults, bunkered tanks, or partially buried tanks are considered aboveground storage containers for purposes of this part.

Complex means a facility possessing a combination of transportation-related and non-transportation-related components that is subject to the jurisdiction of more than one Federal agency under section 311(j) of the CWA.

(a)(1) Except as otherwise provided in this section, if your facility, or mobile or portable facility, was in operation on or before August 16, 2002, you must maintain your Plan, but must amend it, if necessary to ensure compliance with this part, and implement the amended Plan no later than November 10, 2011. If such a facility becomes operational after August 16, 2002, through November 10, 2011, and could reasonably be expected to have a discharge as described in §112.1(b), you must prepare and implement a Plan on or before November 10, 2011. If such a facility (excluding oil production facilities) becomes operational after November 10, 2011, and could reasonably be expected to have a discharge as described in §112.1(b), you must prepare and implement a Plan before you begin operations. You are not required to prepare a new Plan each time you move a mobile or portable facility to a new site; the Plan may be general. When you move the mobile or portable facility, you must locate and install it using the discharge prevention practices outlined in the Plan for the facility. The Plan is applicable only while the mobile or portable facility is in a fixed (non-transportation) operating mode.

(2) If your drilling, production or workover facility, including a mobile or portable facility, is offshore or has an offshore component; or your onshore facility is required to have and submit a Facility Response Plan pursuant to 40 CFR 112.20(a), and was in operation on or before August 16, 2002, you must maintain your Plan, but must amend it, if necessary to ensure compliance with this part, and implement the amended Plan no later than November 10, 2010. If such a facility becomes operational after August 16, 2002, through November 10, 2010, and could reasonably be expected to have a discharge as described in §112.1(b), you must prepare and implement a Plan on or before November 10, 2010. If such a facility (excluding oil production facilities) becomes operational after November 10, 2010, and could reasonably be expected to have a discharge as described in §112.1(b), you must prepare and implement a Plan before you begin operations. You are not required to prepare a new Plan each time you move a mobile or portable facility to a new site; the Plan may be general. When you move the mobile or portable facility, you must locate and install it using the discharge prevention practices outlined in the Plan for the facility. The Plan is applicable only while the mobile or portable facility is in a fixed (non-transportation) operating mode.

(b) If your oil production facility as described in paragraph (a)(1) of this section becomes operational after November 10, 2011, or as described in paragraph (a)(2) of this section becomes operational after November 10, 2010, and could reasonably be expected to have a discharge as described in §112.1(b), you must prepare and implement a Plan within six months after you begin operations.

(c) [Reserved]

(d) Except as provided in §112.6, a licensed Professional Engineer must review and certify a Plan for it to be effective to satisfy the requirements of this part.

(1) By means of this certification the Professional Engineer attests:

(i) That he is familiar with the requirements of this part ;

(ii) That he or his agent has visited and examined the facility; (iii) That the Plan has been prepared in accordance with good engineering practice, including consideration of applicable industry standards, and with the requirements of this part;

Additionally, you must meet the following requirements:

(i) Failure analysis, in lieu of the requirements in §112.7(b). Where experience indicates a reasonable potential for equipment failure (such as loading or unloading equipment, tank overflow, rupture, or leakage, or any other equipment known to be a source of discharge), include in your Plan a prediction of the direction and total quantity of oil which could be discharged from the facility as a result of each type of major equipment failure. (ii) Bulk storage container secondary containment, in lieu of the requirements in §§112.8(c)(2) and (c)(11) and 112.12(c)(2) and (c)(11). Construct all bulk storage container installations (except mobile refuelers and other non- transportation-related tank trucks), including mobile or portable oil storage containers, so that you provide a secondary means of containment for the entire capacity of the largest single container plus additional capacity to contain precipitation. Dikes, containment curbs, and pits are commonly employed for this purpose. You may also use an alternative system consisting of a drainage trench enclosure that must be arranged so that any discharge will terminate and be safely confined in a catchment basin or holding pond. Position or locate mobile or portable oil storage containers to prevent a discharge as described in §112.1(b).

(iii) Overfill prevention, in lieu of the requirements in §§112.8(c)(8) and 112.12(c)(8).

§ 112.7 General requirements for Spill Prevention, Control, and Countermeasure Plans.

If you are the owner or operator of a facility subject to this part you must prepare a Plan in accordance with good engineering practices. The Plan must have the full approval of management at a level of authority to commit the necessary resources to fully implement the Plan. You must prepare the Plan in writing. If you do not follow the sequence specified in this section for the Plan, you must prepare an equivalent Plan acceptable to the Regional Administrator that meets all of the applicable requirements listed in this part, and you must supplement it with a section cross-referencing the location of requirements listed in this part and the equivalent requirements in the other prevention plan. If the Plan calls for additional facilities or procedures, methods, or equipment not yet fully operational, you must discuss these items in separate paragraphs, and must explain separately the details of installation and operational start-up. As detailed elsewhere in this section, you must also:

(a)(1) Include a discussion of your facility's conformance with the requirements listed in this part. (2) Comply with all applicable requirements listed in this part. Except as provided in §112.6, your Plan may deviate from the requirements in paragraphs (g), (h)(2) and (3), and (i) of this section and the requirements in subparts B and C of this part, except the secondary containment requirements in paragraphs (c) and (h)(1) of this section, and §§112.8(c)(2), 112.8(c)(11), 112.9(c)(2), 112.9(d)(3), 112.10(c), 112.12(c)(2), and 112.12(c)(11), where applicable to a specific facility, if you provide equivalent environmental protection by some other means of spill prevention, control, or countermeasure. Where your Plan does not conform to the applicable requirements in paragraphs (g), (h)(2) and (3), and (i) of this section, or the requirements of subparts B and C of this part, except the secondary containment requirements in paragraph (c) and (h)(1) of this section, and §§112.8(c)(2), 112.8(c)(11), 112.9(c)(2), 112.10(c), 112.12(c)(2), and 112.12(c)(11), you must state the reasons for nonconformance in your Plan and describe in detail alternate methods and how you will achieve equivalent environmental protection. If the Regional Administrator determines that the measures described in your Plan do not provide equivalent environmental protection, he may require that you amend your Plan, following the procedures in §112.4(d) and (e).

(3) Describe in your Plan the physical layout of the facility and include a facility diagram, which must mark the location and contents of each fixed oil storage container and the storage area where mobile or portable containers are located. The facility diagram must identify the location of and mark as “exempt” underground tanks that are otherwise exempted from the requirements of this part under §112.1(d)(4). The facility diagram must also include all transfer stations and connecting pipes, including intra-facility gathering lines that are otherwise exempted from the requirements of this part under §112.1(d)(11). You must also address in your Plan:

(i) The type of oil in each fixed container and its storage capacity. For mobile or portable containers, either provide the type of oil and storage capacity for each container or provide an estimate of the potential number of mobile or portable containers, the types of oil, and anticipated storage capacities;

(ii) Discharge prevention measures including procedures for routine handling of products (loading, unloading, and facility transfers, etc.);

(iii) Discharge or drainage controls such as secondary containment around containers and other structures, equipment, and procedures for the control of a discharge;

(iv) Countermeasures for discharge discovery, response, and cleanup (both the facility's capability and those that might be required of a contractor);

(v) Methods of disposal of recovered materials in accordance with applicable legal requirements; and

(vi) Contact list and phone numbers for the facility response coordinator, National Response Center, cleanup contractors with whom you have an agreement for response, and all appropriate Federal, State, and local agencies who must be contacted in case of a discharge as described in §112.1(b).

(4) Unless you have submitted a response plan under §112.20, provide information and procedures in your Plan to enable a person reporting a discharge as described in §112.1(b) to relate information on the exact address or location and phone number of the facility; the date and time of the discharge, the type of material discharged; estimates of the total quantity discharged; estimates of the quantity discharged as described in §112.1(b); the source of the discharge; a description of all affected media; the cause of the discharge; any damages or injuries caused by the discharge; actions being used to stop, remove, and mitigate the effects of the discharge; whether an evacuation may be needed; and, the names of individuals and/or organizations who have also been contacted.

(5) Unless you have submitted a response plan under §112.20, organize portions of the Plan describing procedures you will use when a discharge occurs in a way that will make them readily usable in an emergency, and include appropriate supporting material as appendices.

(b) Where experience indicates a reasonable potential for equipment failure (such as loading or unloading equipment, tank overflow, rupture, or leakage, or any other equipment known to be a source of a discharge), include in your Plan a prediction of the direction, rate of flow, and total quantity of oil which could be discharged from the facility as a result of each type of major equipment failure.

(c) Provide appropriate containment and/or diversionary structures or equipment to prevent a discharge as described in §112.1(b), except as provided in paragraph (k) of this section for qualified oil-filled operational equipment, and except as provided in §112.9(d)(3) for flowlines and intra-facility gathering lines at an oil production facility. The entire containment system, including walls and floor, must be capable of containing oil and must be constructed so that any discharge from a primary containment system, such as a tank, will not escape the containment system before cleanup occurs. In determining the method, design, and capacity for secondary containment, you need only to address the typical failure mode, and the most likely quantity of oil that would be discharged. Secondary containment may be either active or passive in design. At a minimum, you must use one of the following prevention systems or its equivalent:

(1) For onshore facilities:

(i) Dikes, berms, or retaining walls sufficiently impervious to contain oil;

(ii) Curbing or drip pans;

(iii) Sumps and collection systems;

(iv) Culverting, gutters, or other drainage systems;

(v) Weirs, booms, or other barriers;

(vi) Spill diversion ponds;

(vii) Retention ponds; or

(viii) Sorbent materials.

(2) For offshore facilities:

(i) Curbing or drip pans; or

(ii) Sumps and collection systems.

(d) Provided your Plan is certified by a licensed Professional Engineer under §112.3(d), or, in the case of a qualified facility that meets the criteria in §112.3(g), the relevant sections of your Plan are certified by a licensed Professional Engineer under §112.6(d), if you determine that the installation of any of the structures or pieces of equipment listed in paragraphs (c) and (h)(1) of this section, and §§112.8(c)(2), 112.8(c)(11), 112.9(c)(2), 112.10(c), 112.12(c)(2), and 112.12(c)(11) to prevent a discharge as described in §112.1(b) from any onshore or offshore facility is not practicable, you must clearly explain in your Plan why such measures are not practicable; for bulk storage containers, conduct both periodic integrity testing of the containers and periodic integrity and leak testing of the valves and piping; and, unless you have submitted a response plan under §112.20, provide in your Plan the following:

(1) An oil spill contingency plan following the provisions of part 109 of this chapter.

(2) A written commitment of manpower, equipment, and materials required to expeditiously control and remove any quantity of oil discharged that may be harmful.

(e) Inspections, tests, and records. Conduct inspections and tests required by this part in accordance with written procedures that you or the certifying engineer develop for the facility. You must keep these written procedures and a record of the inspections and tests, signed by the appropriate supervisor or inspector, with the SPCC Plan for a period of three years. Records of inspections and tests kept under usual and customary business practices will suffice for purposes of this paragraph.

(f) Personnel, training, and discharge prevention procedures. (1) At a minimum, train your oil-handling personnel in the operation and maintenance of equipment to prevent discharges; discharge procedure protocols; applicable pollution control laws, rules, and regulations; general facility operations; and, the contents of the facility SPCC Plan. (2) Designate a person at each applicable facility who is accountable for discharge prevention and who reports to facility management.

(3) Schedule and conduct discharge prevention briefings for your oil-handling personnel at least once a year to assure adequate understanding of the SPCC Plan for that facility. Such briefings must highlight and describe known discharges as described in §112.1(b) or failures, malfunctioning components, and any recently developed precautionary measures.

(g) Security (excluding oil production facilities). Describe in your Plan how you secure and control access to the oil handling, processing and storage areas; secure master flow and drain valves; prevent unauthorized access to starter controls on oil pumps; secure out-of-service and loading/unloading connections of oil pipelines; and address the appropriateness of security lighting to both prevent acts of vandalism and assist in the discovery of oil discharges.

(h) Facility tank car and tank truck loading/unloading rack (excluding offshore facilities).

(1) Where loading/unloading rack drainage does not flow into a catchment basin or treatment facility designed to handle discharges, use a quick drainage system for tank car or tank truck loading/unloading racks. You must design any containment system to hold at least the maximum capacity of any single compartment of a tank car or tank truck loaded or unloaded at the facility.

(2) Provide an interlocked warning light or physical barrier system, warning signs, wheel chocks or vehicle brake interlock system in the area adjacent to a loading/unloading rack, to prevent vehicles from departing before complete disconnection of flexible or fixed oil transfer lines.

(3) Prior to filling and departure of any tank car or tank truck, closely inspect for discharges the lowermost drain and all outlets of such vehicles, and if necessary, ensure that they are tightened, adjusted, or replaced to prevent liquid discharge while in transit.

(i) If a field-constructed aboveground container undergoes a repair, alteration, reconstruction, or a change in service that might affect the risk of a discharge or failure due to brittle fracture or other catastrophe, or has discharged oil or failed due to brittle fracture failure or other catastrophe, evaluate the container for risk of discharge or failure due to brittle fracture or other catastrophe, and as necessary, take appropriate action.

(j) In addition to the minimal prevention standards listed under this section, include in your Plan a complete discussion of conformance with the applicable requirements and other effective discharge prevention and containment procedures listed in this part or any applicable more stringent State rules, regulations, and guidelines.

(k) Qualified Oil-filled Operational Equipment. The owner or operator of a facility with oil-filled operational equipment that meets the qualification criteria in paragraph (k)(1) of this sub-section may choose to implement for this qualified oil-filled operational equipment the alternate requirements as described in paragraph (k)(2) of this sub-section in lieu of general secondary containment required in paragraph (c) of this section.

(1) Qualification Criteria—Reportable Discharge History: The owner or operator of a facility that has had no single discharge as described in §112.1(b) from any oil-filled operational equipment exceeding 1,000 U.S. gallons or no two discharges as described in §112.1(b) from any oil-filled operational equipment each exceeding 42 U.S. gallons within any twelve month period in the three years prior to the SPCC Plan certification date, or since becoming subject to this part if the facility has been in operation for less than three years (other than oil discharges as described in §112.1(b) that are the result of natural disasters, acts of war or terrorism); and

(2) Alternative Requirements to General Secondary Containment. If secondary containment is not provided for qualified oil-filled operational equipment pursuant to paragraph (c) of this section, the owner or operator of a facility with qualified oil-filled operational equipment must:

(i) Establish and document the facility procedures for inspections or a monitoring program to detect equipment failure and/or a discharge; and

(ii) Unless you have submitted a response plan under §112.20, provide in your Plan the following: (A) An oil spill contingency plan following the provisions of part 109 of this chapter.

Subpart B—Requirements for Petroleum Oils and Non-Petroleum Oils, Except Animal Fats and Oils and Greases, and Fish and Marine Mammal Oils; and Vegetable Oils (Including Oils from Seeds, Nuts, Fruits, and Kernels)

Source: 67 FR 47146, July 17, 2002, unless otherwise noted.

§ 112.8 Spill Prevention, Control, and Countermeasure Plan requirements for onshore facilities (excluding production facilities).

If you are the owner or operator of an onshore facility (excluding a production facility), you must:

(a) Meet the general requirements for the Plan listed under §112.7, and the specific discharge prevention and containment procedures listed in this section.

(b) Facility drainage. (1) Restrain drainage from diked storage areas by valves to prevent a discharge into the drainage system or facility effluent treatment system, except where facility systems are designed to control such discharge. You may empty diked areas by pumps or ejectors; however, you must manually activate these pumps or ejectors and must inspect the condition of the accumulation before starting, to ensure no oil will be discharged.

(2) Use valves of manual, open-and-closed design, for the drainage of diked areas. You may not use flapper-type drain valves to drain diked areas. If your facility drainage drains directly into a watercourse and not into an on-site wastewater treatment plant, you must inspect and may drain uncontaminated retained stormwater, as provided in paragraphs (c)(3)(ii), (iii), and (iv) of this section.

(3) Design facility drainage systems from undiked areas with a potential for a discharge (such as where piping is located outside containment walls or where tank truck discharges may occur outside the loading area) to flow into ponds, lagoons, or catchment basins designed to retain oil or return it to the facility. You must not locate catchment basins in areas subject to periodic flooding.

(4) If facility drainage is not engineered as in paragraph (b)(3) of this section, equip the final discharge of all ditches inside the facility with a diversion system that would, in the event of an uncontrolled discharge, retain oil in the facility.

(5) Where drainage waters are treated in more than one treatment unit and such treatment is continuous, and pump transfer is needed, provide two “lift” pumps and permanently install at least one of the pumps. Whatever techniques you use, you must engineer facility drainage systems to prevent a discharge as described in §112.1(b) in case there is an equipment failure or human error at the facility.

(c) Bulk storage containers. (1) Not use a container for the storage of oil unless its material and construction are compatible with the material stored and conditions of storage such as pressure and temperature.

(2) Construct all bulk storage tank installations (except mobile refuelers and other non-transportation-related tank trucks) so that you provide a secondary means of containment for the entire capacity of the largest single container and sufficient freeboard to contain precipitation. You must ensure that diked areas are sufficiently impervious to contain discharged oil. Dikes, containment curbs, and pits are commonly employed for this purpose. You may also use an alternative system consisting of a drainage trench enclosure that must be arranged so that any discharge will terminate and be safely confined in a facility catchment basin or holding pond. (3) Not allow drainage of uncontaminated rainwater from the diked area into a storm drain or discharge of an effluent into an open watercourse, lake, or pond, bypassing the facility treatment system unless you:

(i) Normally keep the bypass valve sealed closed.

(ii) Inspect the retained rainwater to ensure that its presence will not cause a discharge as described in §112.1(b).

(iii) Open the bypass valve and reseal it following drainage under responsible supervision; and

(iv) Keep adequate records of such events, for example, any records required under permits issued in accordance with §§122.41(j)(2) and 122.41(m)(3) of this chapter.

(4) Protect any completely buried metallic storage tank installed on or after January 10, 1974 from corrosion by coatings or cathodic protection compatible with local soil conditions. You must regularly leak test such completely buried metallic storage tanks.

(5) Not use partially buried or bunkered metallic tanks for the storage of oil, unless you protect the buried section of the tank from corrosion. You must protect partially buried and bunkered tanks from corrosion by coatings or cathodic protection compatible with local soil conditions.

(6) Test or inspect each aboveground container for integrity on a regular schedule and whenever you make material repairs. You must determine, in accordance with industry standards, the appropriate qualifications for personnel performing tests and inspections, the frequency and type of testing and inspections, which take into account container size, configuration, and design (such as containers that are: shop-built, field-erected, skid-mounted, elevated, equipped with a liner, double-walled, or partially buried). Examples of these integrity tests include, but are not limited to: visual inspection, hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, or other systems of non-destructive testing. You must keep comparison records and you must also inspect the container's supports and foundations. In addition, you must frequently inspect the outside of the container for signs of deterioration, discharges, or accumulation of oil inside diked areas. Records of inspections and tests kept under usual and customary business practices satisfy the recordkeeping requirements of this paragraph.

(7) Control leakage through defective internal heating coils by monitoring the steam return and exhaust lines for contamination from internal heating coils that discharge into an open watercourse, or pass the steam return or exhaust lines through a settling tank, skimmer, or other separation or retention system.

(8) Engineer or update each container installation in accordance with good engineering practice to avoid discharges. You must provide at least one of the following devices:

(i) High liquid level alarms with an audible or visual signal at a constantly attended operation or surveillance station. In smaller facilities an audible air vent may suffice.

(ii) High liquid level pump cutoff devices set to stop flow at a predetermined container content level.

(iii) Direct audible or code signal communication between the container gauger and the pumping station.

(iv) A fast response system for determining the liquid level of each bulk storage container such as digital computers, telepulse, or direct vision gauges. If you use this alternative, a person must be present to monitor gauges and the overall filling of bulk storage containers.

(v) You must regularly test liquid level sensing devices to ensure proper operation.

(9) Observe effluent treatment facilities frequently enough to detect possible system upsets that could cause a discharge as described in §112.1(b). (10) Promptly correct visible discharges which result in a loss of oil from the container, including but not limited to seams, gaskets, piping, pumps, valves, rivets, and bolts. You must promptly remove any accumulations of oil in diked areas.

(11) Position or locate mobile or portable oil storage containers to prevent a discharge as described in §112.1(b). Except for mobile refuelers and other non-transportation-related tank trucks, you must furnish a secondary means of containment, such as a dike or catchment basin, sufficient to contain the capacity of the largest single compartment or container with sufficient freeboard to contain precipitation.

(d) Facility transfer operations, pumping, and facility process. (1) Provide buried piping that is installed or replaced on or after August 16, 2002, with a protective wrapping and coating. You must also cathodically protect such buried piping installations or otherwise satisfy the corrosion protection standards for piping in part 280 of this chapter or a State program approved under part 281 of this chapter. If a section of buried line is exposed for any reason, you must carefully inspect it for deterioration. If you find corrosion damage, you must undertake additional examination and corrective action as indicated by the magnitude of the damage.

(2) Cap or blank-flange the terminal connection at the transfer point and mark it as to origin when piping is not in service or is in standby service for an extended time.

(3) Properly design pipe supports to minimize abrasion and corrosion and allow for expansion and contraction.

(4) Regularly inspect all aboveground valves, piping, and appurtenances. During the inspection you must assess the general condition of items, such as flange joints, expansion joints, valve glands and bodies, catch pans, pipeline supports, locking of valves, and metal surfaces. You must also conduct integrity and leak testing of buried piping at the time of installation, modification, construction, relocation, or replacement.

(5) Warn all vehicles entering the facility to be sure that no vehicle will endanger aboveground piping or other oil transfer operations.

§ 112.10 Spill Prevention, Control, and Countermeasure Plan requirements for onshore oil drilling and workover facilities.

If you are the owner or operator of an onshore oil drilling and workover facility, you must: (a) Meet the general requirements listed under §112.7, and also meet the specific discharge prevention and containment procedures listed under this section.

(b) Position or locate mobile drilling or workover equipment so as to prevent a discharge as described in §112.1(b).

(c) Provide catchment basins or diversion structures to intercept and contain discharges of fuel, crude oil, or oily drilling fluids.

(d) Install a blowout prevention (BOP) assembly and well control system before drilling below any casing string or during workover operations. The BOP assembly and well control system must be capable of controlling any well-head pressure that may be encountered while that BOP assembly and well control system are on the well.

§ 112.11 Spill Prevention, Control, and Countermeasure Plan requirements for offshore oil drilling, production, or workover facilities.

If you are the owner or operator of an offshore oil drilling, production, or workover facility, you must:

(a) Meet the general requirements listed under §112.7, and also meet the specific discharge prevention and containment procedures listed under this section.

(b) Use oil drainage collection equipment to prevent and control small oil discharges around pumps, glands, valves, flanges, expansion joints, hoses, drain lines, separators, treaters, tanks, and associated equipment. You must control and direct facility drains toward a central collection sump to prevent the facility from having a discharge as described in §112.1(b). Where drains and sumps are not practicable, you must remove oil contained in collection equipment as often as necessary to prevent overflow.

(c) For facilities employing a sump system, provide adequately sized sump and drains and make available a spare pump to remove liquid from the sump and assure that oil does not escape. You must employ a regularly scheduled preventive maintenance inspection and testing program to assure reliable operation of the liquid removal system and pump start-up device. Redundant automatic sump pumps and control devices may be required on some installations.

(d) At facilities with areas where separators and treaters are equipped with dump valves which predominantly fail in the closed position and where pollution risk is high, specially equip the facility to prevent the discharge of oil. You must prevent the discharge of oil by:

(1) Extending the flare line to a diked area if the separator is near shore;

(2) Equipping the separator with a high liquid level sensor that will automatically shut in wells producing to the separator; or

(3) Installing parallel redundant dump valves.

(e) Equip atmospheric storage or surge containers with high liquid level sensing devices that activate an alarm or control the flow, or otherwise prevent discharges.

(f) Equip pressure containers with high and low pressure sensing devices that activate an alarm or control the flow.

(g) Equip containers with suitable corrosion protection.

(h) Prepare and maintain at the facility a written procedure within the Plan for inspecting and testing pollution prevention equipment and systems.

(i) Conduct testing and inspection of the pollution prevention equipment and systems at the facility on a scheduled periodic basis, commensurate with the complexity, conditions, and circumstances of the facility and any other appropriate regulations. You must use simulated discharges for testing and inspecting human and equipment pollution control and countermeasure systems. (j) Describe in detailed records surface and subsurface well shut-in valves and devices in use at the facility for each well sufficiently to determine their method of activation or control, such as pressure differential, change in fluid or flow conditions, combination of pressure and flow, manual or remote control mechanisms.

(k) Install a BOP assembly and well control system during workover operations and before drilling below any casing string. The BOP assembly and well control system must be capable of controlling any well-head pressure that may be encountered while the BOP assembly and well control system are on the well.

(l) Equip all manifolds (headers) with check valves on individual flowlines.

(m) Equip the flowline with a high pressure sensing device and shut-in valve at the wellhead if the shut-in well pressure is greater than the working pressure of the flowline and manifold valves up to and including the header valves. Alternatively you may provide a pressure relief system for flowlines.

(n) Protect all piping appurtenant to the facility from corrosion, such as with protective coatings or cathodic protection.

(o) Adequately protect sub-marine piping appurtenant to the facility against environmental stresses and other activities such as fishing operations.

(p) Maintain sub-marine piping appurtenant to the facility in good operating condition at all times. You must periodically and according to a schedule inspect or test such piping for failures. You must document and keep a record of such inspections or tests at the facility.

§ 112.12 Spill Prevention, Control, and Countermeasure Plan requirements.

If you are the owner or operator of an onshore facility, you must:

(a) Meet the general requirements for the Plan listed under §112.7, and the specific discharge prevention and containment procedures listed in this section.

(b) Facility drainage. (1) Restrain drainage from diked storage areas by valves to prevent a discharge into the drainage system or facility effluent treatment system, except where facility systems are designed to control such discharge. You may empty diked areas by pumps or ejectors; however, you must manually activate these pumps or ejectors and must inspect the condition of the accumulation before starting, to ensure no oil will be discharged.

(2) Use valves of manual, open-and-closed design, for the drainage of diked areas. You may not use flapper-type drain valves to drain diked areas. If your facility drainage drains directly into a watercourse and not into an on-site wastewater treatment plant, you must inspect and may drain uncontaminated retained stormwater, subject to the requirements of paragraphs (c)(3)(ii), (iii), and (iv) of this section.

(3) Design facility drainage systems from undiked areas with a potential for a discharge (such as where piping is located outside containment walls or where tank truck discharges may occur outside the loading area) to flow into ponds, lagoons, or catchment basins designed to retain oil or return it to the facility. You must not locate catchment basins in areas subject to periodic flooding.

(4) If facility drainage is not engineered as in paragraph (b)(3) of this section, equip the final discharge of all ditches inside the facility with a diversion system that would, in the event of an uncontrolled discharge, retain oil in the facility.

(5) Where drainage waters are treated in more than one treatment unit and such treatment is continuous, and pump transfer is needed, provide two “lift” pumps and permanently install at least one of the pumps. Whatever techniques you use, you must engineer facility drainage systems to prevent a discharge as described in §112.1(b) in case there is an equipment failure or human error at the facility.

(c) Bulk storage containers. (1) Not use a container for the storage of oil unless its material and construction are compatible with the material stored and conditions of storage such as pressure and temperature.

(2) Construct all bulk storage tank installations (except mobile refuelers and other non-transportation-related tank trucks) so that you provide a secondary means of containment for the entire capacity of the largest single container and sufficient freeboard to contain precipitation. You must ensure that diked areas are sufficiently impervious to contain discharged oil. Dikes, containment curbs, and pits are commonly employed for this purpose. You may also use an alternative system consisting of a drainage trench enclosure that must be arranged so that any discharge will terminate and be safely confined in a facility catchment basin or holding pond.

(3) Not allow drainage of uncontaminated rainwater from the diked area into a storm drain or discharge of an effluent into an open watercourse, lake, or pond, bypassing the facility treatment system unless you:

(i) Normally keep the bypass valve sealed closed.

(ii) Inspect the retained rainwater to ensure that its presence will not cause a discharge as described in §112.1(b).

(iii) Open the bypass valve and reseal it following drainage under responsible supervision; and

(iv) Keep adequate records of such events, for example, any records required under permits issued in accordance with §§122.41(j)(2) and 122.41(m)(3) of this chapter.

(4) Protect any completely buried metallic storage tank installed on or after January 10, 1974 from corrosion by coatings or cathodic protection compatible with local soil conditions. You must regularly leak test such completely buried metallic storage tanks.

(5) Not use partially buried or bunkered metallic tanks for the storage of oil, unless you protect the buried section of the tank from corrosion. You must protect partially buried and bunkered tanks from corrosion by coatings or cathodic protection compatible with local soil conditions.

(6) Bulk storage container inspections.

(i) Except for containers that meet the criteria provided in paragraph (c)(6)(ii) of this section, test or inspect each aboveground container for integrity on a regular schedule and whenever you make material repairs. You must determine, in accordance with industry standards, the appropriate qualifications for personnel performing tests and inspections, the frequency and type of testing and inspections, which take into account container size, configuration, and design (such as containers that are: shop-built, field-erected, skid-mounted, elevated, equipped with a liner, double-walled, or partially buried). Examples of these integrity tests include, but are not limited to: Visual inspection, hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, or other systems of non- destructive testing. You must keep comparison records and you must also inspect the container's supports and foundations. In addition, you must frequently inspect the outside of the container for signs of deterioration, discharges, or accumulation of oil inside diked areas. Records of inspections and tests kept under usual and customary business practices satisfy the recordkeeping requirements of this paragraph.

(ii) For bulk storage containers that are subject to 21 CFR part 110, are elevated, constructed of austenitic stainless steel, have no external insulation, and are shop-fabricated, conduct formal visual inspection on a regular schedule. In addition, you must frequently inspect the outside of the container for signs of deterioration, discharges, or accumulation of oil inside diked areas. You must determine and document in the Plan the appropriate qualifications for personnel performing tests and inspections. Records of inspections and tests kept under usual and customary business practices satisfy the recordkeeping requirements of this paragraph (c)(6).

(7) Control leakage through defective internal heating coils by monitoring the steam return and exhaust lines for contamination from internal heating coils that discharge into an open watercourse, or pass the steam return or exhaust lines through a settling tank, skimmer, or other separation or retention system. (8) Engineer or update each container installation in accordance with good engineering practice to avoid discharges. You must provide at least one of the following devices:

(i) High liquid level alarms with an audible or visual signal at a constantly attended operation or surveillance station. In smaller facilities an audible air vent may suffice.

(ii) High liquid level pump cutoff devices set to stop flow at a predetermined container content level.

(iii) Direct audible or code signal communication between the container gauger and the pumping station.

(iv) A fast response system for determining the liquid level of each bulk storage container such as digital computers, telepulse, or direct vision gauges. If you use this alternative, a person must be present to monitor gauges and the overall filling of bulk storage containers.

(v) You must regularly test liquid level sensing devices to ensure proper operation.

(9) Observe effluent treatment facilities frequently enough to detect possible system upsets that could cause a discharge as described in §112.1(b).

(10) Promptly correct visible discharges which result in a loss of oil from the container, including but not limited to seams, gaskets, piping, pumps, valves, rivets, and bolts. You must promptly remove any accumulations of oil in diked areas.

(11) Position or locate mobile or portable oil storage containers to prevent a discharge as described in §112.1(b). Except for mobile refuelers and other non-transportation-related tank trucks, you must furnish a secondary means of containment, such as a dike or catchment basin, sufficient to contain the capacity of the largest single compartment or container with sufficient freeboard to contain precipitation.

(d) Facility transfer operations, pumping, and facility process. (1) Provide buried piping that is installed or replaced on or after August 16, 2002, with a protective wrapping and coating. You must also cathodically protect such buried piping installations or otherwise satisfy the corrosion protection standards for piping in part 280 of this chapter or a State program approved under part 281 of this chapter. If a section of buried line is exposed for any reason, you must carefully inspect it for deterioration. If you find corrosion damage, you must undertake additional examination and corrective action as indicated by the magnitude of the damage.

(2) Cap or blank-flange the terminal connection at the transfer point and mark it as to origin when piping is not in service or is in standby service for an extended time.

(3) Properly design pipe supports to minimize abrasion and corrosion and allow for expansion and contraction.

(4) Regularly inspect all aboveground valves, piping, and appurtenances. During the inspection you must assess the general condition of items, such as flange joints, expansion joints, valve glands and bodies, catch pans, pipeline supports, locking of valves, and metal surfaces. You must also conduct integrity and leak testing of buried piping at the time of installation, modification, construction, relocation, or replacement.

(5) Warn all vehicles entering the facility to be sure that no vehicle will endanger aboveground piping or other oil transfer operations.
