2017 Annual Pretreatment Report, King County Industrial Waste Program iv EXECUTIVE SUMMARY

The King County Industrial Waste Program (KCIW) regulates more than 600 commercial and industrial customers of King County’s regional wastewater system. The program functions under the County’s Wastewater Treatment Division (WTD) as a delegated pretreatment program required by the National Pollutant Discharge Elimination System (NPDES) permits for operation of the division’s wastewater treatment plants. The annual pretreatment report contains all the NPDES permit-required elements and summarizes KCIW’s 2017 achievements in the areas of operations, special projects and activities, and public outreach. KCIW issues wastewater discharge approvals, conducts inspections, monitors discharges, and takes enforcement actions against facilities that violate requirements in order to protect public health, the County’s wastewater treatment plants, and biosolids quality and to enhance the environment. KCIW works cooperatively with its customers, provides technical assistance, and offers awards to those that consistently meet requirements. In 2017, violations by KCIW-regulated companies and facilities did not cause problems at the County’s wastewater treatment plants. There were no NPDES exceptions for effluent discharges into Puget Sound at any of the plants attributed to an industrial facility, and metal concentrations in biosolids continued to meet the strictest U.S. Environmental Protection Agency standards. Highlights of KCIW activities in 2017 are as follows: • Issued 303 wastewater discharge approvals (new, renewed, and revised letters of authorization; discharge authorizations; waste discharge permits; and verbal approvals) • Inspected and monitored significant industrial users and took enforcement actions against those that violated requirements • Received approval from the Washington State Department of Ecology for the evaluation of local discharge limits for Brightwater Treatment Plant • Implemented a regulatory approach for smaller breweries and developed best management practices for all breweries • Prioritized and completed an initial evaluation of 66 high-priority facilities as a result of the 2016 Industrial User Survey, which surveyed over 17,000 businesses in the County’s wastewater treatment system

2017 Annual Pretreatment Report, King County Industrial Waste Program vi 1.0 INTRODUCTION

This report presents information on the King County Wastewater Treatment Division’s (WTD) industrial pretreatment program for 2017. Annual pretreatment program reports are required in the National Pollutant Discharge Elimination System (NPDES) permits issued to the division’s wastewater treatment plants. WTD serves approximately 1.7 million people. Its service area includes most urban areas of King County and parts of south Snohomish County and northeast Pierce County. The wastewater treatment system includes three regional treatment plants (West Point in the City of Seattle, South Plant in the City of Renton, and Brightwater in south Snohomish County); one small treatment plant and one community septic system on Vashon Island; another small treatment plant in the City of Carnation; four combined sewer overflow (CSO) treatment facilities in Seattle; over 390 miles of pipes; 26 regulator stations; 47 pump stations; and 38 CSO outfalls. The King County Industrial Waste Program (KCIW) administers and implements the pretreatment program. KCIW duties include issuing approvals for discharging industrial wastewater to the sewer system, monitoring permitted dischargers, conducting inspections, and taking enforcement action when necessary. All required pretreatment program data are included in the appendices of this report in the order listed in the NPDES permits. The narrative of the report provides context for the data. It describes KCIW’s operations, special projects and activities, and public outreach in 2017. Lastly, the narrative of the report summarizes the collective performance of the wastewater treatment plants as it relates to pretreatment program performance.

2017 Annual Pretreatment Report, King County Industrial Waste Program 2 2.0 INDUSTRIAL WASTE PROGRAM OPERATIONS

This chapter describes the major work that KCIW has done in 2017 to ensure that industrial waste discharges to the King County wastewater treatment system are safe. This includes issuing discharge approvals, conducting inspections, and taking enforcement actions.

2.1 Industrial Wastewater Discharge Approvals KCIW issues several types of industrial wastewater discharge approvals (control documents). The type of approval is determined by the nature of the business, volume and characteristics of the wastewater, and potential risks to the wastewater treatment system.

2.1.1 Types of Control Documents The following types of control documents are issued for discharges of industrial wastewater to King County sewers: • Discharge permits. These permits are issued to companies or facilities defined as significant industrial users (SIUs) if they meet one or more of the following criteria:

o Subject to federal categorical standards o Discharge more than 25,000 gallons per day (gpd) (with exceptions as outlined under “Discharge authorizations” below)

o Represent an apparent risk to publicly owned treatment works o Warrant significant regulatory attention • Zero discharge authorizations. KCIW issues a letter to categorical facilities that propose to not discharge to the sewer system (i.e. zero dischargers). The authorization requires annual self-certification and water balance information from the industrial user. • Discharge authorizations. KCIW issues major and minor discharge authorizations (DAs). Minor DAs typically have fewer requirements than major DAs and do not require self-monitoring; major DAs typically require a limited amount of self-monitoring. These approvals apply to wastewater discharges generally between 1,000 gpd and 25,000 gpd. Facilities determined to meet the non-significant categorical industrial user (NSCIU) definition are issued minor DAs. DAs may be issued to facilities that discharge more than 25,000 gpd in cases of compatible waste (biochemical oxygen demand [BOD], suspended solids mainly from food processors) and where the discharge is determined to pose minimum risk to the system. • Letters of authorization. KCIW issues a letter of authorization (LA) for discharges less than 1,000 gpd and for short-term construction dewatering projects. The majority of the letters issued annually are for short-term construction dewatering projects.

2017 Annual Pretreatment Report, King County Industrial Waste Program 3

• General letters of authorization. KCIW issues general letters of authorization (GLAs) to small construction dewatering projects that meet all of the following criteria:

o Maximum discharge volume is 25,000 gpd o Construction activity is on a site less than one acre o The site is not contaminated with any pollutants of concern other than turbidity from construction activity.

o An on-site pretreatment system must be in place, as described in a KCIW technical memorandum dated October 7, 2011, to meet KCIW local limits for settleable solids. • Verbal authorizations and No Control Document Required Notifications. KCIW issues verbal authorizations for small-volume and one-time discharges and issues a No Control Document Required email for discharges that do not require a formal document, typically for very small volumes of ongoing discharges that pose negligible risk to the wastewater system.

2.1.2 Control Document Activity in 2017 Table 1 shows the type and number of active control documents from 2013 through 2017 (year- end numbers); Table 2 shows distribution of the major categories of active control documents at the end of 2017; and Table 3 shows the number and type of new, renewed, and revised control documents in 2017. Appendices A and C contain detailed lists of industrial users and those issued control documents in 2017. Parts 1 and 2 of Appendix A report the CSO outfall for each of the active permits and major and minor DAs, as required by the NPDES permit for West Point.

2.2 Inspections KCIW inspects each SIU at least once annually and all facilities that have applied to renew their permits, DAs, or LAs. KCIW staff conduct other miscellaneous inspections alone or jointly with other agency staff at various facilities. In 2017, the program was responsible for conducting 339 inspections (Table 4). For a detailed listing of all inspections conducted in 2017, see Appendix C.

2.3 Monitoring

2.3.1 Self-Monitoring In general, facilities must collect samples and report data according to a schedule based on the type of control document: • With few exceptions, facilities with discharge permits are required to routinely monitor their discharges and report monthly. • Holders of DAs must collect data and report the findings on a less frequent basis, typically quarterly or semiannually. • Those with construction LAs are required to sample and monitor during construction and, in some cases, to report at the conclusion of the project. For a summary of self-monitoring data submitted by industrial users, see Appendix C.

2.3.2 Compliance and Surcharge Program Monitoring Compliance monitoring provides a snapshot of regulated dischargers. KCIW collects compliance samples and other data from facilities with discharge permits and DAs (if under the High- Strength Waste Surcharge Program). The goal is to sample each permitted facility twice a year. In addition, KCIW conducts post-violation sampling and inspections to verify that violating conditions have been mitigated. In 2017, KCIW monitored the following parameters in addition to established compliance parameters for facilities with active permits: • Continuous pH at metal finishing facilities • Dissolved sulfides, turbidity, and settleable solids at construction sites, transfer stations, and industrial laundry facilities on a case-by-case basis • Semivolatile organic compounds analysis (base neutral acids [BNAs]) at facilities with permits due to expire in the upcoming year • Polychlorinated biphenyls (PCBs) at selected sites Facilities under the High-Strength Waste Surcharge Program are monitored for BOD and total suspended solids (TSS) in accordance with procedures established for the program. Three-day sampling events are scheduled either once or twice annually based on the facility’s history with the program, the number of samples in its database, and whether it has discharged more than 600 pounds of combined BOD and TSS per day (the King County Code threshold for monitoring). Table 5 shows the type and number of compliance, High-Strength Waste Surcharge Program, Key Manhole Program, and post-violation samples collected during 2017 for each parameter. For a detailed summary of KCIW data collected from SIUs, see Appendix C.

2.4 Enforcement Activities The 2008 King County Industrial Waste Enforcement Response Plan (www.kingcounty.gov/ about/policies/rules/utilities/put8121pr.aspx) guides enforcement of King County Code Chapter 28.84.060 and its associated local limits. According to the plan, notices of violation (NOVs) are issued to dischargers who commit the following types of violations: • Discharge violation for discharging more than the allowable contaminants or wastewater volume • Permit violation for violating conditions of a permit, DA, or other written authorization • Reporting violation for failing to submit a required report • King County Code violation The enforcement response plan provides KCIW with a variety of tools for returning industrial dischargers to compliance as quickly as possible. These tools include the imposition of

2017 Annual Pretreatment Report, King County Industrial Waste Program 7

compliance schedules, fines, charges for post-violation monitoring and inspections, and charges to recover costs for damages caused by noncompliant discharges.

2.4.1 Notices of Violation Issued in 2017 Table 6 lists the type and number of NOVs issued in 2017. KCIW issued a total of 39 NOVs for 28 facilities. NOVs were issued for facilities that discharge to the West Point, South Plant, Brightwater, and Vashon treatment plants. No NOVs were issued to facilities that discharge to the Carnation Treatment Plant. Three facilities were found to be in significant noncompliance. In October 2017, the program published all appropriate violations and enforcement actions through June 2017 in The Seattle Times. Violations and actions that occurred from July to December 2017 will be published in 2018. None of the violations caused NPDES exceptions at the County’s wastewater treatment plants. For a complete list of 2017 NOVs and a copy of The Seattle Times notifications, see Appendix D. Table 6. Type and Number of Notices of Violation in 2017

Type of Violation Number Discharge limits 15 Permit 7 Reporting 16 King County Code 1

2.4.2 Fines Imposed in 2017 In 2017, KCIW fined four companies for a total of $18,110. The largest fine was issued to Washington State Department of Transportation – Interstate-90 Two Way Transit and High- Occupancy Vehicle Project – Fire Life Systems Testing for $5,585. A total of $60,185 was levied in post-violation charges during the year. The largest post-violation charge was issued to Northwest Gourmet Food Products Inc. – Renton Facility for $7,050.

2.5 Cost Recovery KCIW charges for its services in the following ways: • Compliance monitoring and administrative charges. These charges are intended to recover KCIW’s costs for inspecting, sampling, and analyzing permitted industrial discharges for heavy metals and fats, oils, and grease (FOG) and for the overall management of permits. • Post-violation charges. Out-of-compliance facilities are responsible for the costs of the additional work associated with violations, including sampling, inspection, and documentation of an enforcement action. • Charges for issuing control documents. Facilities pay the costs for issuing permits, DAs, and LAs. King County Code allows for one free revision within the five-year cycle and specifies that no charge be levied for any KCIW-initiated revisions. • High-strength waste treatment surcharge. A surcharge is applied for discharges with BOD greater than 300 milligrams per liter (mg/L) and TSS greater than 400 mg/L. The

2017 Annual Pretreatment Report, King County Industrial Waste Program 8

surcharge includes an administrative charge that recovers costs for sampling, analysis, inspection, and billing.

Each year, KCIW reviews and updates the fees based on operating costs from the previous year. Table 7 shows the rates in effect for 2017.

2.6 Biosolids and Effluent Quality at Wastewater Treatment Plants King County’s wastewater treatment plants provide secondary treatment and mesophilic anaerobic digestion of solids, followed by dewatering. This section reports on the quality of biosolids produced at the three regional treatment plants in 2017 and then describes conditions at the regional (Brightwater, West Point, and South) and local treatment plants (Vashon and

2017 Annual Pretreatment Report, King County Industrial Waste Program 9

Carnation) related to influent, effluent, and biosolids quality. Influent and effluent data and removal efficiencies from the three regional plants are discussed in Appendix B.

2.6.1 2017 Biosolids Data In 2017, the regional treatment plants continued to produce biosolids with exceptionally low concentrations of heavy metals, organic compounds, and pathogenic microbes. Class B biosolids met the strictest standards set by the U.S. Environmental Protection Agency (EPA) (40 CFR Part 503.13) for in-land recycling projects (Table 8). Long-term data (Appendix B) on metals associated with industrial activities indicate that levels are stable with minor and slight fluctuations, which demonstrates the effectiveness of the pretreatment program.

2.6.2 Brightwater Treatment Plant, South Snohomish County No unusual operating conditions related to the discharge of industrial waste occurred at the Brightwater Treatment Plant in 2017. An operational summary follows: • Flow averaged 17.9 million gallons per day (mgd); 0.2 mgd of this flow was beneficially applied as recycled water and 0.5 mgd of the total flow average of 17.9 mgd was wastewater from the West Point service area. This flow was directed to Brightwater during the first half of 2017 to provide relief to West Point. In addition to the 17.9 mgd of flow, 1.7 mgd of Brightwater wastewater was sent to South Plant (during most of 2017) to facilitate maintenance, respond to filterability issues in the secondary process, and distribute Brightwater’s load while it received West Point flows. • Brightwater receives a substantial BOD load from breweries and wineries, especially during the fall months. These industrial wastes have a very low alkalinity. Sampling in 2014 indicated that the two largest breweries and wineries

2017 Annual Pretreatment Report, King County Industrial Waste Program 10

contributed about 6,300 pounds per day (lb/day) of BOD on average. Such a load would have accounted for 14 percent of Brightwater’s influent BOD load in 2017. • Brightwater does not receive septage or solids from other treatment facilities. • Secondary treatment at Brightwater is provided by membrane bioreactor (MBR) technology (GE/Zenon’s “ZeeWeed” ultra-filtration membrane with an effective pore size of 0.04 micrometers). This technology meets Class A reclaimed water coagulation and filtration requirements. The performance of the system relies on the ability of the membranes to filter the secondary activated biomass (mixed liquor suspended solids [MLSS]):

o The membranes performed well in 2017. Final effluent quality averaged less than 1.2-mg/L BOD and less than 2.0-mg/L TSS.

o The filterability of the MLSS continued to be a concern in 2017, especially in the winter when rainfall causes flows to increase and water temperatures to decrease. It does not appear to be a source control issue.

o Large foaming events in the secondary aeration process occurred less frequently than in previous years, likely because of implementation of better foam and scum removal. Most foaming events are likely not a source control issue, but the byproduct of physical design and operational conditions of the secondary process.

o A MBR secondary pilot plant was operated during 2016 and 2017 to better understand how influent quality and operating conditions affect filterability, foaming, and secondary process performance. The pilot plant operated under a variety of conditions, but did not identify any specific reasons for reduced filterability. • Twenty-five percent sodium hydroxide (NaOH) solution is added continuously to the secondary process to keep the effluent pH above 6.0; 12.5 percent sodium hypochlorite (NaOCl) solution is also added continuously for disinfection. NaOH dosing is required because the influent alkalinity is insufficient to balance the alkalinity consumed by the secondary nitrification process. The problem is exacerbated during rainstorms when low-alkalinity infiltration and inflow enter the influent. The continuous and high doses of NaOH and NaOCl result in effluent sodium levels that are relatively high for reclaimed water use.

2.6.3 Carnation Treatment Plant, City of Carnation No unusual operating conditions related to the discharge of industrial waste occurred at the Carnation Treatment Plant in 2017. An operational summary follows: • Flow to the Carnation plant averaged 0.097 mgd in 2017. Flow to the plant has been fairly consistent—on both an annual as well as monthly basis—since the plant started operating in 2008. • The plant processes wastewater through a secondary/MBR process (with “ZeeWeed” ultra-filtration membranes) followed by ultraviolet disinfection.

2017 Annual Pretreatment Report, King County Industrial Waste Program 11

• The effluent was applied as Class A reclaimed water for wetlands enhancement at the Chinook Bend Natural Area. All permit effluent quality requirements for the wetlands application were satisfied in 2017. • Considerable amounts of alkalinity [either 25 percent NaOH solution or 50 percent Mg(OH)2 solution] were added to the secondary/MBR process to maintain the effluent pH above pH 6.0. The addition is required because the influent alkalinity is insufficient to balance the alkalinity consumed during nitrification. Efforts in 2017 continued to focus on maximizing the denitrification process, which recovers alkalinity as well as lowers the effluent nitrogen load.

• A 50 percent magnesium hydroxide [Mg(OH)2] solution was used to supply alkalinity to the secondary process from January through April 2017. Mg(OH)2 was used instead of the 25 percent NaOH solution because it is safer to handle, poses fewer consequences if spilled [e.g., the resulting wastewater pH will be much lower with Mg(OH)2 than NaOH], and reduces the sodium content in the effluent. It was also used in hopes of seeing an improvement in the filtering characteristics of the mixed liquor; however, there was no apparent improvement. It did increase the magnesium levels in the sludge that is hauled to South Plant for further treatment. • NaOCl and citric acid were occasionally added to the secondary process to maintain filter performance. The frequency of cleaning has stayed relatively the same year after year.

2.6.4 South Treatment Plant, City of Renton South Treatment Plant consistently performed well in 2017. No unusual or detrimental influent conditions hindered the plant’s ability to comply with effluent quality, biosolids quality, or Class A reclaimed water permit conditions. South Plant’s flow averaged 76.2 mgd. Information on 2017 plant operations is as follows: • Fairly heavy amounts of airplane deicer were discharged to South Plant from SeaTac Airport during wet weather months. BOD loads in early 2017 were especially high, averaging 14,600 and 18,400 lb/day for January and February, respectively. These loads accounted for 6 percent and 12 percent of South Plant’s influent BOD loads (and about 9 percent and 18 percent of the BOD load to the secondary process). Effluent TSS and BOD levels were below permit limits during the months with higher deicer BOD loads. • South Plant received 27.2 million gallons of septage in 2017. Septage solids accounted for about 8 percent of all influent solids. South Plant also receives secondary sludge from other County treatment facilities (Carnation, Vashon, and Beulah Cove). • There was one occasion in 2017 when a glue-like substance was discharged to South Plant via the Septage Receiving Facility. The substance was mostly captured in the hoppers of Septage Receiving while some of the substance made its way to the influent bar screens and associated equipment. Substantial resources were required to remove and dispose of this substance as well as for clean-up activities at the facility. The substance did not appear to impact final effluent quality, reclaimed water quality, or biosolids quality.

2017 Annual Pretreatment Report, King County Industrial Waste Program 12

• South Plant received thickened raw sludge from West Point from January through August, with the heaviest loads occurring from March through May. In fact, West Point sludge accounted for nearly 6 percent of South Plant’s annual biosolids load in 2017 and 20 percent and 25 percent of the loads in April and May, respectively. Some metals concentrations in South Plant’s biosolids changed in a manner consistent with levels typically found in West Point’s biosolids. For example, the lead level in South Plant biosolids increased while receiving West Point sludge. No other notable impacts occurred to South Plant’s effluent, reclaimed water, and biosolids quality. • As mentioned previously, a notable amount of wastewater from the Brightwater service area was directed to South Plant through most of 2017 (1.7-mgd annual average). There were no notable impacts to South Plant’s effluent, reclaimed water, and biosolids quality.

2.6.5 Vashon Treatment Plant, Vashon Island The Vashon Treatment Plant operated well in 2017. No unusual influent conditions caused processing problems or issues with effluent quality. Flow averaged 0.175 mgd, which is reflective of the rainy year that characterized 2017. Influent loads averaged 442 lb/day BOD and 346 lb/day TSS. Influent loads did not vary much throughout the year, with maximum-month loads of 488 lb/day BOD and 446 lb/day TSS. Soda ash (sodium carbonate, Na2CO3) was occasionally added to the plant’s oxidation ditch when the effluent pH was nearing 6.0. The occasional low pH events were not a source control issue, but rather the result of biological nitrification that consumes alkalinity and stormwater infiltration and inflow with essentially no alkalinity.

2.6.6 West Point Treatment Plant, City of Seattle

On February 9, 2017, there was a major internal flooding event at the West Point Treatment Plant. As a result of the flooding event, major equipment and processes were damaged and the plant was unable to meet its NPDES permit limits for a few months while it was recovering. In addition, after recovering from the flooding event, saltwater intrusion into the system caused NPDES violations in late October and early November. The saltwater entered the collection system during high tide conditions through a failed flap gate, impacting plant processes and performance. As a result, a temporary stop log was put in place until a replacement gate could be manufactured and installed. West Point treated an annual average flow rate of 99.2 mgd for 2017.

Although several major projects continued to progress in 2017 (in planning, design, and/or under construction), much of the year was spent on recovery efforts, including the replacement of several major below-grade equipment (e.g., motor control centers and other electrical equipment). Work to optimize the systems to control emissions from the influent pump engines continued through 2017. Among the major technical components installed were a biogas treatment system, an automated air-to-fuel controller, and a three-way catalyst. By the end of 2017, the systems were able to meet the expected emissions limits on a consistent basis.

In a typical year, a digester is taken down for cleaning and routine periodic maintenance work; however, this was cancelled in 2016 because of digester foaming at West Point. In 2017, the plant continued to face challenges with digester foaming before the February 9, 2017, flooding

event. The transfer of thickened, raw sludge to South Plant had been initiated at the end of 2016 to reduce the load to the digesters. After the flooding event, solids continued to be transported to South Plant because the West Point digesters were offline. During the recovery period, the plant was able to clean one digester and seeded with solids from South Plant.

The cogeneration project, which provided the plant with two, 2.3-megawatt cogeneration engines, completed its fourth year of commercial operation in 2017. The engines process the digester biogas to produce electricity and heat for the plant. During 2017, gas production and energy production were offline for a significant period of time because there was no available digester gas due to the February 9, 2017, flooding event.

The Oxygen Generation and Dissolution System Project continued to evaluate upgrades and/or replacements for the existing vacuum swing adsorption (VSA) generation and dissolution system. Planning continued in 2017 to first pilot test the new aerators on two trains before full- scale implementation. However, replacement of the existing VSA systems has been delayed.

Lastly, in 2017, West Point completed its conversion and migration to a new Emerson Ovation control system.

3.0 SPECIAL PROJECTS AND ACTIVITIES

This chapter describes special projects and activities that KCIW undertook in 2017.

3.1 Activities Regarding Specific Types of Wastes

3.1.1 Construction Dewatering Discharges In 2017, demand for authorizations to discharge construction dewatering water to King County sewers continued to take up a significant amount of time as in previous years. In addition to smaller projects, the program continued to manage major regional construction projects, including the North and East Link projects ( to Northgate and Bellevue corridor), several King County WTD capital projects including three projects associated with the Georgetown CSO facility, the City of Seattle Elliott Bay Seawall Replacement project, and Washington State Department of Transportation projects associated with the Alaskan Way Viaduct Replacement. To respond to an increase in smaller projects, KCIW developed and issued GLAs to construction projects that meet the following criteria: • Maximum discharge volume is 25,000 gpd • Construction activity is on a site less than one acre • The site is not contaminated with any pollutants of concern other than turbidity from construction activity. • An on-site pretreatment system must be in place, as described in a KCIW technical memorandum dated October 7, 2011, to meet KCIW local limits for settleable solids. During 2017, KCIW issued 65 GLAs to qualified construction projects. Inspections of randomly selected GLA projects indicated that project owners are in compliance and are satisfied with the expedited authorization process and ease of application. During 2017, KCIW performed the following activities on construction-related documents and procedures: • Updated the application form for larger projects that require individual authorizations. The revised form provides clearer guidance for applicants and is expected to improve the rate of applications received that are complete. • Updated the internal scoring criteria matrix to identify projects that require an authorization versus a full permit. This will further standardize the procedure for selecting the type of authorization. • Created selection criteria for frequency of sampling and reporting. When used, the criteria will enable the investigators to select quickly from a standardized list and will also improve standardization. • Updated the inspection form for construction sites • Updated the “frequently asked questions”

2017 Annual Pretreatment Report, King County Industrial Waste Program 15

• Updated the Web pages

3.1.2 Dental Waste Each year, KCIW randomly selects and inspects a portion of all dental offices in its service area. The goal is to ensure that these offices are following best management practices (BMPs), including installation and maintenance of amalgam separator units (ASUs) to capture wastes containing mercury before they enter the County’s wastewater system. In July 2017, EPA published new regulations for dental offices in the Code of Federal Regulations, 40 CFR Part 441. Most dental offices (about 95 percent) in King County’s wastewater service area already have installed approved ASUs. However, the new rule applies to some dental offices that were previously exempt under King County’s BMPs, including endodontists and some pediatric dental specialists. Since EPA published the new regulations for dental offices, KCIW has developed materials to assist dentists in meeting the requirements. KCIW has updated its website and posted the one- time compliance report form online for dentists to fill out and submit to KCIW. KCIW is working on procedures to receive and track the one-time compliance reports and is developing a certificate to issue to dentists that have submitted a complete one-time compliance report as confirmation and recognition of their compliance. In 2017, 50 dental offices from KCIW’s database were inspected. All of these offices were in compliance. Since the dental waste program began in 2001, the annual median mercury concentrations in biosolids have steadily declined. In the past few years, these concentrations have stabilized at around 0.7 mg/kg at West Point and South Plant and 0.6 mg/kg at Brightwater, which began operating in 2011 (see Table 8 in Chapter 2).

3.1.3 Fats, Oils, and Grease A KCIW compliance investigator serves on the PreFOG & Wastewater Committee, which is a work group of pretreatment inspectors from sewer agencies in Western Washington and the Portland, Oregon, area. The goal of this group is to prevent free-floating FOG from entering, blocking, and causing backups in local sewer lines. Although KCIW did not participate in meetings in 2017, it continued to track the activities of the group. In 2017, KCIW continued to focus on minimizing the discharge of free-floating FOG from applicable permitted industrial users. These facilities are required to submit a free-floating FOG control plan, semiannual reports documenting compliance with BMPs, and the results of increased monitoring of free-floating FOG. KCIW developed a standard operating procedure for the measurement of free-floating FOG for customers and published the procedure on its website.

3.1.4 Winery and Brewery Waste In 2017, KCIW implemented permitting guidelines for breweries. Breweries must apply for a DA if they meet one or more of the following criteria: • Produce 3,000 or more barrels of beer per year • Send 1,000 or more gallons of wastewater to the sewer each day

2017 Annual Pretreatment Report, King County Industrial Waste Program 16

• Are located in the Carnation or Vashon treatment plant collection zones Breweries that do not meet these permitting criteria must still meet King County local discharge limits. To assist breweries in complying with regulations and limits, KCIW developed BMPs for breweries. The BMPs explain how to reduce solids in wastewater, control pH, store chemicals, prevent chemical spills, keep records, and conserve water. KCIW developed a template discharge authorization document for breweries and issued an additional three DAs under the new permitting guidelines and BMPs.

3.2 Key Manhole Program The purpose of the Key Manhole Program is to monitor and isolate potential sources of spills or slug loads from industrial sources, to characterize wastewater for program development such as setting local limits, and to characterize wastewater near industrial discharge facilities. The two main components of the program—responding to unusual occurrences and conducting surveillance monitoring—are described below.

3.2.1 Response to Unusual Occurrences KCIW staff work with staff from the County’s treatment plants and Conveyance Inspection and Flow Monitoring group (Conveyance Inspection group), local sewer agencies, and other regulatory agencies to evaluate and respond to referrals of unusual occurrences in the sanitary sewer system. Staff also respond to notifications from the Washington State Department of Ecology (Ecology) Environmental Report Tracking System (ERTS). The ERTS notifies local agencies of complaints that have the potential to expose illicit discharges to sanitary sewers. KCIW evaluates each referral and responds accordingly. Responses include follow-up contact with industrial facilities, inspections, sampling, and surveillance monitoring at key sampling manholes. In 2017, KCIW published a guidance document that outlines roles and responsibilities and the process and procedures for handling unusual occurrences such as spills, ERTS, and complaint calls. In 2017, KCIW responded to 27 reports of unusual occurrences, including four ERTS notifications. KCIW developed a standard operating procedure to respond more effectively to referrals. Table 9 lists the occurrences and responses organized by treatment plant service area. Table 9. Unusual Occurrences in 2017 No. Unusual Occurrence Date Response Reported Brightwater Service Area 1 KCIW received a call from the Nov. 8, Nov. 29, 2016 – The assigned investigator followed Woodinville Water District (WWD) 2016 up with WWD to discuss the extent and possible concerning sewer line conditions causes of the damage. downstream from NW Cascade, a KCIW developed and conducted continuous pH permitted facility. and H2S monitoring in late summer of 2017. KCIW will send the findings to WWD and coordinate with them on communication plans for several businesses in the service area. In addition, KCIW will update the one permitted facility in the area to a full permit.

City of Black Diamond staff were provided the list and reviewed it to see if any of the businesses had the potential to be the source. An inspection with Black Diamond staff of the local lines was conducted to observe conditions. The KCIW investigator inspected the King County pump station and King County lines. A potential local source was identified; however, there was no strong evidence that it was reaching the King County line. Reviewing the initial email from the Conveyance Inspection group, the location of the equipment was determined to be on the opposite end of the Black Diamond trunk. Therefore, the source was not likely to be industrial. There are multiple lateral sewers connecting to the King County line between the business center and the location of the complaint. The Conveyance Inspection group was notified by email of the findings. This record was closed after conferring with the Industrial Waste Program Manager. 3 South Plant staff emailed KCIW to July 10, July 10 – An investigator was assigned to the report a large amount of grease 2017 incident.

3.2.2 Surveillance Monitoring KCIW investigates potential sources of spills, slug loads, or illicit discharges by monitoring contaminants of concern at strategic manholes near suspected industrial users or possible polluters. In addition, KCIW designs key manhole studies to collect technical data in the regional wastewater system to use in the evaluation of local limits. In 2017, KCIW conducted seven-day surveillance monitoring in five manholes in the Woodinville sewer district to evaluate sewer line conditions, focusing on pH and sulfide. The evaluation revealed several intermittent spikes of high levels of atmospheric sulfide downstream from Northwest Cascade Inc., a chemical toilet company. As a result, KCIW plans to update the Northwest Cascade authorization in 2018 to a full permit and will develop conditions to minimize potential impacts to sewer lines.

Key manhole surveillance monitoring was also conducted for three days at the Oberto Brands meat processing compliance site and at another manhole downstream of the site. The purpose of the investigation was to compare pH data from a variety of monitoring equipment. KCIW staff inserted two different types of pH measuring equipment at the compliance site. The evaluation

2017 Annual Pretreatment Report, King County Industrial Waste Program 22

revealed significant differences between King County’s data and data from the compliance site’s pH meters. KCIW will follow up with Oberto Brands to evaluate the discrepancies.

3.3 PIMS Database KCIW uses the Pretreatment Information Management System (PIMS) to manage and record data on permitted companies, including compliance activities such as inspections and sampling, and to generate mailing lists, standard correspondence documents, permit documents, and facility information query reports. In 2017, KCIW continued to make the following improvements to PIMS: • Modified and added PIMS-generated letters and permitting documents to streamline the process • Conducted a comprehensive evaluation and needs assessment of the PIMS database with support from King County Information Technology (KCIT) department staff. The final report from KCIT will be used by KCIW management to seek budget monies for updates to the current database. The next version of the PIMS database is expected to address Web-based reporting of self-monitoring data by industrial users.

3.4 Septage KCIW continued to work with South Plant staff to permit septage waste from businesses in accordance with septage acceptance guidelines developed for facilities discharging industrial and commercial wastewater into on-site sewerage systems. KCIW continued to use the computer tools and criteria developed in 2015, including improved heavy metals evaluation criteria, sampling data workflow, and tracking tools, to record data criteria exceedances, inspections, and data letters sent to haulers. Septage-related activities in 2017 included the following: • KCIW processed two septage acceptance applications. The first request was for a building in that sustained damage to its side sewer and needed to divert its sanitary waste stream until repairs could be completed. The second application was from the University of Washington to haul sewage from periodic lift station cleaning and maintenance activities. • Under the random inspection program, KCIW inspected 29 septage hauler deliveries at South Plant on four different days between March and December. The purpose of the inspections was to check and document that each delivery met King County’s criteria. All 29 of the trucks inspected were hauling residential septage only. • South Plant personnel collected 40 random septage samples in 2017. The samples were analyzed for nine metals (arsenic, cadmium, chromium, copper, lead, mercury, nickel, silver, and zinc) at the King County Environmental Laboratory (KCEL). General criteria developed for expected levels of heavy metals in “normal” domestic septage were used to screen the data. For discharges that are out of normal range, haulers are required to supply manifests about the contents of the sampled load. Septage haulers were sent letters along with the sample results and requests for manifests. All loads in question were

2017 Annual Pretreatment Report, King County Industrial Waste Program 23

verified as either residential or commercial in origin. KCIW will continue to track random sampling results, identify any trends of concern, and discuss this information with haulers, as appropriate. • In November 2017, KCIW issued a notice of violation to Evergreen Sanitation, a septage hauler, for discharging unauthorized waste into the septage receiving facility at South Plant. The discharge consisted of a glue-like substance that interfered with treatment plant operations. KCIW is currently preparing its final action to close this matter. • KCIW participated in facilitated process improvement workshops to address septage permitting bottlenecks, better coordinate sampling data, and increase information sharing between its interagency partners. • In November 2017, KCIW representatives attended the annual septage haulers meeting at South Plant to educate septage haulers on procedures for acceptance of septage from commercial businesses, answer questions, and provide copies of the KCIW septage application for commercial facilities. Haulers were also notified that, extending into 2017 and beyond, KCIW will continue to randomly inspect septage trucks and send written results of periodic sampling events to septage haulers. Depending on these sampling results, KCIW may require additional information on the source of hauled septage that exceeds sample screening criteria.

3.5 Source Control Activities

3.5.1 Lower Duwamish Waterway To support Lower Duwamish Waterway (LDW) sediment remediation efforts, KCIW has worked with agency partners to reduce the amount of pollution discharged from permitted industrial sites to combined sewers that discharge to the waterway during combined sewer overflow (CSO) events. The purpose of this source control program is to reduce the potential for recontamination of waterway sediment following cleanup. KCIW conducted the following source control activities in the LDW basin during 2017: • King County source control implementation plan. In 2017, KCIW staff continued to implement the KCIW portion of the King County Source Control Implementation Plan. This work primarily involved implementing the standard pretreatment requirements for industrial users that are located within the LDW basin. • Lower Duwamish Waterway Source Control Work Group. KCIW participates in the Lower Duwamish Waterway Source Control Work Group, which was formed to promote discussion of source control issues that may affect sediment remediation. The group is primarily composed of the three members of the Lower Duwamish Waterway Group (King County, Port of Seattle, and City of Seattle) and the two agencies with regulatory responsibility for different aspects of LDW sediment remediation (Ecology and EPA). It has been meeting regularly for several years. • Urban Waters Initiative inspections. In 2007, Ecology initiated a targeted source control effort in the LDW basin called the Urban Waters Initiative. Inspectors from Ecology’s water quality and hazardous waste programs are implementing the initiative.

2017 Annual Pretreatment Report, King County Industrial Waste Program 24

Under Ecology’s lead, the City of Seattle and KCIW are participating in source control issues relating to stormwater drainage and industrial wastewater pretreatment, respectively. A lead investigator at KCIW also participates in the Duwamish Inspectors Group, which is a forum for inspectors from the City of Seattle, Ecology, King County, and other agencies to discuss regulatory issues in the LDW basin. KCIW compliance investigators send industrial user surveys and conduct inspections based on agency referrals from the Duwamish Inspectors Group. • Technical support for source control studies. WTD sponsors source control studies in the LDW; King County’s Water and Land Resources Division (WLRD) conducts the fieldwork for the studies and KCIW reviews documents and provides technical assistance with reporting. The following is a summary of one of the studies:

o Michigan combined sewer basin study. The goal of the Michigan combined sewer basin study is to identify sources of contaminants to the combined sewer system and to aid in evaluating the potential for CSO discharges to re-contaminate sediments following CSO control. In 2013 and 2014, WLRD staff sampled wastewater at three locations in the basin during base flow and storm flow conditions. The purpose of the sampling was to evaluate potential differences in LDW chemicals of concern from wastewater, infiltration and inflow, and stormwater contributions to the system. KCIW reviewed revised draft reports throughout the project. WTD issued a final report in 2017.

3.5.2 East Waterway To support the East Waterway (EWW) sediment remediation efforts, KCIW is working with agency partners to reduce the amount of pollution discharged from permitted industrial sites to combined sewers that discharge to the waterway during CSO events. The purpose of this source control program is to reduce the potential for recontamination of waterway sediment following cleanup. KCIW conducted the following source control activities in the EWW basin during 2017: • Source control activities in the East Duwamish Waterway area. In 2017, KCIW inspected and collected wastewater samples at selected permitted industrial facilities in the East Duwamish Waterway area. Data from the sampling are being used to assess whether wastewater treatment and/or source control BMPs implemented at the facilities are adequate to control pollutants of concern. • Outreach to businesses in Hanford No. 2 CSO basin. At the request of KCIW, the Local Hazardous Waste Management Program (LHWMP) Technical Assistance & Incentives (TAI) team conducted source control inspections at businesses located in the King County Hanford No. 2 CSO basin. The businesses had been identified through KCIW business surveys and mapping to support WTD source control efforts in the EWW. The visits resulted in the following:

o The TAI team conducted 152 site visits (including initial and follow-up visits) in the area between January and November 2017. The visits focused on on-site technical assistance to small businesses for hazardous material and waste management including storage, spill prevention and disposal, and discharges to

2017 Annual Pretreatment Report, King County Industrial Waste Program 25

sanitary and storm drains. Other services to businesses included EnviroStars consultations and verifications.

o LHWMP issued vouchers to reimburse small quantity generator businesses 75 percent of their costs (up to $599) for purchasing and installing pollution prevention equipment, if needed. In addition, through a contract with the Environmental Coalition of South Seattle, the TAI team also provided spill kits, customized drainage maps, spill plans, and spill cleanup training to businesses that lacked them.

3.6 Surcharge to Treat High-Strength Wastes In January 1977, KCIW implemented a surcharge to recover the cost of treating high-strength waste discharges from industrial facilities. The High-Strength Waste Surcharge Program performs periodic audits to evaluate its effectiveness in recovering costs. In 2015, KCIW and the WTD finance group guided the work of an engineering consultant to update operational costs for BOD and TSS removal at County wastewater treatment plants and to assess surcharge fees for BOD and TSS removal. To support the effort, KCIW staff collected wastewater samples in residential and commercial portions of the wastewater system to evaluate the adequacy of the current domestic-strength equivalence for BOD and TSS and to assess the domestic-strength equivalence for soluble BOD (sBOD). The sBOD data were used to evaluate the feasibility of a surcharge based on dividing total BOD into sBOD and insoluble BOD fractions. The recommendation memorandum and supporting background report on development of revised high-strength waste surcharge rates were completed in 2015. In keeping with King County Code, the recommendations were presented to the WTD director and approved in December 2015. KCIW implemented the revised allocation formula and fees in July 2016. The implementation was guided by a communication plan that included mailing letters to the facilities with estimates of their fee changes and making telephone calls to facilities with more significant changes. WTD will update the surcharge allocation every five years. In 2017, KCIW continued to implement the surcharge rate revisions outlined in last year’s report. The highlights of the surcharge program are as follows: • High-strength surcharge rates are based on system wide annual operating costs allocated among BOD, TSS, and flow, through an engineering and financial analysis of the County’s wastewater treatment system. The BOD and TSS annual operating cost allocations were combined with annual BOD and TSS loadings to the system to derive surcharge rates in units of dollars per pound of BOD or TSS ($/lb BOD or $/lb TSS). The surcharge applies to discharges above the domestic-strength equivalence of 300-mg/L BOD or 400-mg/L TSS because discharges of domestic strength are already captured in the base sewer fee that all dischargers pay. The allocation percentages used in calculating the operating cost allocations were as follows:

o Until June 30, 2016: BOD (18 percent), TSS (33 percent), and flow (49 percent) o After June 30, 2016: BOD (37 percent), TSS (39 percent), and flow (24 percent)

2017 Annual Pretreatment Report, King County Industrial Waste Program 26

• The revised surcharge rates place WTD at a comparable level to other peer sewer utilities on the west coast region of the country. Because the revised rate for BOD nearly doubled, WTD decided to phase this increase over four years. • The TSS rate increase was not as significant and was fully implemented in the first year (effective July 1, 2016). • The previous practice for calculating BOD, TSS, and flow relied on data provided when the industrial user first started discharging or when a user made a major upgrade to their pretreatment system. The revised practice relies on more recent data with a window of four years. Because some industrial users will record large increases in concentrations when transitioning to the use of more recent data, the transition is being implemented over four years. • Per King County Code, KCIW conducts at least twice-per-year sampling of industrial users that discharge more than 600 lb/day of BOD and TSS. Industrial facilities that discharge less than this amount either can be sampled or their waste strength can be classified based on the waste strength of a comparable industrial user. • WTD analysis indicates that it is not cost-effective to recover high-strength waste surcharge costs from industrial users that discharge less than 10 lb/day of BOD and TSS; however, this does not preclude cost recovery in the future if a cost-effective mechanism for recovery can be devised for industrial users or industrial user classifications.

3.7 Review of Businesses in the Service Area Starting in 2015 and continuing in 2017, KCIW undertook a major initiative to review 80,000 businesses in the King County wastewater treatment service area. The purpose of the initiative was to identify businesses that have the potential to discharge non-domestic wastewater to the wastewater collection system and to notify them of pretreatment and federal reporting regulations. In 2017, the goal was to identify and follow up with business that were identified as potential SIUs or categorical industrial users with the information gathered through their submitted survey. The objectives of this review were as follows: • Conduct a survey that complies with federal regulations (40 CFR 403.8) regarding collection and maintenance of basic information about users in the King County wastewater treatment service area that have a potential for discharging non-domestic wastewater. • Notify each business of federal, state, and local pretreatment requirements and federal hazardous waste reporting requirements. • Issue permits to any SIUs found through the survey process. • Use the data collected for source control and share information gathered with local sewer agencies and source control inspectors.

2017 Annual Pretreatment Report, King County Industrial Waste Program 27

3.7.1 Comprehensive Survey A survey was conducted in accordance with Ecology’s Guidance Manual for Performing an Industrial User Survey (Ecology Publication No. 11-10-055). The survey was mailed to 24,000 businesses in the King County service area. Approximately 6,000 completed surveys were returned to King County for evaluation. The remainder of the non-responders (about 18,000) are categorized into groups that can be used for future source control activities. King County has reviewed the data from the 6,000 responses that were collected and sorted them into four groups by priority level. The highest priority level included surveys from respondents that indicated that their company performed categorical processes; discharged, on average, over 20,000 gpd; or had anodizing solutions on-site. KCIW categorized 66 companies into the highest priority level. KCIW worked with a consultant to provide database training for the investigators. The training enabled the investigators to use the 2016 Industrial User Survey database as a customer records management tool and tracking system. All 66 companies were evaluated by an investigator to determine if the company had completed the survey correctly and if they were still active in the King County Service area. For companies that were still active in the service area and had completed the survey correctly, the investigator determined if no control documents are needed or if a permit application is required. KCIW determined 16 companies did not need any type of control document and 11 companies needed to fill out a permit application. The project will continue in 2018 as one of the priority projects for KCIW. The goal for 2018 is to receive the permit applications and issue all required documents to the 11 companies identified as needing applications. King County will continue to update Ecology in annual reports and during annual state pretreatment inspections and will provide a complete final report at the end of the project.

3.7.2 Other Actions In addition to the comprehensive survey, KCIW did the following in 2017: • Continued to compile lists of potential dischargers from sources such as local sewer agencies, EPA, Ecology, LHWMP, county stormwater program inspectors, and the Puget Sound Business Journal. • Used the industrial user database to create a list of businesses that were within the East Waterway CSO basins. The list was further refined by geographic information system analysts and was provided to LHWMP for source control activities. • Received and issued approximately 45 additional surveys that resulted from referrals from other agencies, KCIW staff, or the businesses themselves. • Began the transition to the electronic survey format to incorporate future ad hoc and referral surveys into the database.

4.2 Other Outreach Activities Other KCIW outreach activities in 2017 were as follows: • Annual newsletters. KCIW published two newsletters that focused on technical assistance, regulatory and other program updates, enforcement activities, and recognition of compliance successes. The newsletters were delivered electronically to make it easier for customers to manage delivery preferences and to follow links for more information. • Website. The KCIW website provides access to application forms, permit information, and information for specific business sectors. KCIW is making more information available on the Web to reduce reliance on print materials. In 2017, the home page and forms library were updated to make it easier to find materials and to reduce the need for mailing multiple copies. • Enforcement notification. KCIW published two notifications in The Seattle Times that listed all companies and facilities in the King County wastewater service area that violated permit conditions and described the violations, penalties, and requirements for corrective action. • KCIW programs. Many KCIW programs contain communication elements to reach specific audiences. In 2017, these programs included construction dewatering, brewery BMPs, new rules for dentists, and engagement regarding future changes to the fee structure. In 2017, KCIW created and began phasing in a new graphic identity to make it easier for customers to use materials.

2017 Annual Pretreatment Report, King County Industrial Waste Program 58

APPENDIX B

Results of wastewater sampling at the treatment plants, as specified

The permittee must calculate removal rates for each pollutant and evaluate the adequacy of the existing local limits in prevention of treatment plant interference, pass through of pollutants that could affect receiving water quality, and sludge contamination.

Appendix B consists of two parts: • Part 1. Wastewater sampling data and removal efficiencies, discussion, and tables • Part 2. Long-term biosolids charts

2017 Annual Pretreatment Report, King County Industrial Waste Program 59 Appendix B Part 1

Wastewater sampling data (metals) and removal efficiencies, discussion, and tables

Influent and effluent total metals data were analyzed for the King County Brightwater, South, and West Point treatment plants. Data were collected from the seasonal intensive sampling events at the respective plants and were screened to only include data sets that had paired influent and effluent data for the metals for which King County has developed numerical local discharge limits. Because of the limited amount of data available during a given calendar year, data were collected for a five-year timeframe (2013 to 2017) to have a larger data set for analysis.

The treatment plant data were used to evaluate influent and effluent concentrations and to calculate removal efficiencies. The results from the Brightwater, South, and West Point treatment plants are provided in the attached Tables 1 , 2, and 3, respectively.

Metals effluent concentrations were all well below the levels of concern for exceeding water quality criteria when taking into account the allowable acute or chronic water quality criteria mixing zones established for each treatment plant. These water quality criteria for metals at the respective treatment plants are presented in the 2010 King County evaluation of local discharge limits.

For further discussion of treatment plant results, please note the following: • Table 1. Brightwater Treatment Plant (BWTP) (2013–2017): The Brightwater Treatment Plant data for 2017 indicated the removal efficiency for chromium, copper, lead, mercury, and nickel in 2017 appeared to be less than that of 2016 and less than that of the overall 2013 to 2017 overall average removal efficiency, with exception of lead, which was better. Copper removal efficiency in 2017 was similar to that of the overall average 2013 to 2017 removal efficiency. However, the trend analysis indicated the plant removal efficiency appears to be improving. • Table 2. South Treatment Plant (STP) (2013–2017): The South Treatment Plant data for 2017 indicated the removal efficiency for lead, nickel, and silver in 2017 appeared to be less than that of 2016 and, in the case of nickel, less than that of the overall 2013 to 2017 average removal efficiency, with exception of silver, which was better. Lead removal efficiency in 2017 was similar to that of the overall average 2013 to 2017 removal efficiency. However, the trend analysis indicated the plant removal efficiency appears to be improving. • Table 3. West Point Treatment Plant (WPTP) (2013–2017): The West Point Treatment Plant data indicated lower efficiency during 2017 with respect to the past four years for all metals tested. The lower efficiency appears to be a result of the February 9 flooding incident that caused the plant to operate at reduced capacity (i.e., no secondary process and associated digestion) for about 3 months. However, the lower removal efficiency did not affect the overall trend and, as indicated graphically, the plant’s removal efficiency trend appears to be improving.

2017 Annual Pretreatment Report, King County Industrial Waste Program 60 Biosolids concentrations for 2017 were well below acceptable use standards, as discussed in other portions of this report (see Table 8 in the narrative report). See the attached charts for the long-term trends of Brightwater, South, and West Point treatment plants biosolids data. Polychlorinated biphenyls in biosolids are found mostly below or just above methods detection levels. West Point has higher detections most likely because discharges to the plant are from the older portion of the system (City of Seattle and combined system).

There were no recorded incidents of inhibition of wastewater treatment plant operations relating to discharges from industrial users. A review of the influent and effluent organics data including tentatively identified compounds did not reveal any new sources of pollutants of concern from industrial sources.

Notes: (A) Sample collected during large storm event which resulted in a shortened hydraulic retention time for the treatment plant. The February 2014 discharge monitoring report indicated that the peak flow exceeded 300 million gallons per day resulting in 21.79 million gallons being diverted around secondary treatment. Despite negative removal efficiency value, influent and effluent concentrations appear to be valid.

APPENDIX C

Status of program implementation

Appendix C consists of seven sections: 1. Section c.i. Any substantial modifications to the pretreatment program as originally approved by the Washington State Department of Ecology (Ecology), including staffing and funding levels. 2. Section c.ii. Any interference, upset, or permit violations experienced at the publically owned treatment works (POTW) that are directly attributable to the wastes from industrial users. 3. Section c.iii. A list of industrial users that were inspected and or monitored, and a summary of the results. • Part 1. All facilities inspected by the King County Industrial Waste Program (KCIW) in 2017, listed in chronological order. During 2017, all significant industrial users (SIUs) were inspected at least once. • Part 2. A summary of self-monitoring analyses submitted to KCIW by SIUs during 2017. The data have been entered into the Pretreatment Information Management System (PIMS) database. • Part 3. A summary of KCIW monitoring for 2017. This summary lists the date each facility was monitored and the pollutants/parameters monitored. Exceptions are listed in the following table, Part 4. • Part 4. A list of facilities not monitored at least twice during 2017. KCIW’s goal is to sample all SIUs at least twice annually. The federal pretreatment program requires that all SIUs that discharge during the year be sampled at least once. KCIW met this standard, with the exception of two facilities because of database protocols/issues. 4. Section c.iv. A list of industrial users scheduled for inspection and/or monitoring for the next year (2018) and expected frequencies. 5. Section c.v. A list of industrial users notified of promulgated pretreatment standards and/or local standards as required in 40 CFR 403.8(f)(2)(iii). The list must indicate which industrial users are on compliance schedules and the final date of compliance for each. 6. Section c.vi. A list of industrial users issued waste discharge permits. • Part 1. A list of all industrial users issued waste discharge permits. These are all SIUs. This list includes middle-tier categorical industrial users as defined by 40 CFR 403.8(f)(2)(v)(B) and (C). • Part 2. A list of categorical industrial users issued a zero discharge authorization. • Part 3. A list of all industrial users issued letters of authorization and minor and major waste discharge authorizations. This lists all nonsignificant categorical industrial users (NSCIUs) in accordance with 40 CFR 403.12(i). 7. Section c.vii. Planned changes in the pretreatment program implementation plan.

2017 Annual Pretreatment Report, King County Industrial Waste Program 84 Appendix C Section c.i

Any substantial modifications to the pretreatment program as originally approved by Ecology, including staffing and funding levels

There were no substantial modifications to the program in 2017. A summary of personnel changes and training as well as KCIW’s most significant work plan items in 2017 are outlined below. Personnel KCIW’s total full-time equivalent technical positions remained at 15 for core activities. In 2017, two investigators were promoted from level I to level II. Mark Henley joined the program in October, replacing Despina Strong as the unit supervisor. Training In 2017, KCIW continued to focus on training for employees, particularly in technical skill development and internal cross-training. With a number of new employees on board, the program focused on on-the-job training in technical skills associated with each new position. Safety training The Wastewater Treatment Division Safety Office conducted audiometric fit tests. KCIW developed a list of annual field-related safety huddles and began implementing them. Technical training and skill development courses Staff attended leadership training, took classes in project management, Lean, and Equity and Social Justice. To remain informed and to network with other professionals in the region, KCIW staff attended the National Pretreatment Conference and the Pacific Northwest Pretreatment Conference.

2017 Annual Pretreatment Report, King County Industrial Waste Program 85 Program Priorities in 2018 The table below outlines the program’s most significant priorities in 2018.

King County Industrial Waste Program 2018 Work Plan Regulatory compliance • Issue and administer permits, discharge authorizations, and letters of authorization • Inspect SIUs and conduct compliance sampling • Take enforcement actions and publish violators in a newspaper of largest circulation • Develop clearer guidelines for permitting decisions • Implement general authorization for larger construction projects • Implement the new Dental Rule and continue to conduct random inspections

• Develop permitting recommendations for wineries • Follow up on the comprehensive industrial user survey of King County service area • Respond to complaint calls and conduct studies to update local limits • Conduct random inspections and collect samples to monitor the discharge of septage waste at South Treatment Plant • Develop a comprehensive plan for PIMS database Regulatory compliance – Lower Duwamish and East Waterway Source Control Projects • Continue involvement with the Duwamish Source Control Work Group • Continue to provide support to East Waterway Project focusing on several industrial facilities within the Superfund area Customer support • Continue to work closely with local sewer agency staff • Provide technical information materials to industrial users and other stakeholders • Publish newsletters • Continue to hold meetings with industrial users as needed to solicit input into new processes • Continue to issue awards to industrial users with excellent compliance Cost recovery support • Continue to collect data to recover costs for high-strength waste discharges • Continue to collect data and calculate costs for monitoring of industrial users

2017 Annual Pretreatment Report, King County Industrial Waste Program 86 Appendix C Section c.ii

Any interference, upset, or permit violations experienced at the POTW that are directly attributable to the wastes from industrial users

During 2017, none of King County’s wastewater treatment plants (Brightwater, Carnation, South, West Point, Vashon Island) had any National Pollutant Discharge Elimination System permit exceptions attributable to wastes from industrial users. There were no instances of interference attributable to wastes from industrial users at the County’s wastewater treatment plants, except for South Plant. A septage hauler dumped commercial waste that was not authorized and this caused non-routine maintenance at the plant’s influent screens. At the end of 2017, this incident was under investigation and is pending further enforcement action in 2018.

2017 Annual Pretreatment Report, King County Industrial Waste Program 87 Appendix C Section c.iii - Part 1 All facilities inspected by KCIW in 2017, listed in chronological order. During 2017, all SIUs were inspected at least once.

2017 Annual Pretreatment Report, King County Industrial Waste Program 494 Appendix C Section c.v

List of industrial users notified of promulgated pretreatment standards and/or local standards as required in 40 CFR 403.8(f)(2)(iii). The list must indicate which industrial users are on compliance schedules and the final date of compliance for each.

Please refer to Appendix A, which lists new sources that started discharging to the King County sewer system in 2017. Industrial users are also identified in Appendix C, Section c.vi, Part 1 and Part 2. Identified in the category column are noncategorical dischargers subject to King County local limits. All facilities under compliance schedules because of noncompliance are listed in Appendix D, Section d.ii, Part 2. In July 2017, the U.S. Environmental Protection Agency (EPA) published new regulations for dental offices in the Code of Federal Regulations, 40 CFR Part 441. Most dental offices (about 95 percent) in King County’s wastewater service area already have installed approved amalgam separator units. However, the new rule applies to some dental offices that were previously exempt under King County’s best management practices, including endodontists and some pediatric specialties. Since EPA published the new regulations for dental offices, KCIW has developed materials to assist dentists in meeting the requirements. KCIW has updated its website and posted the one-time compliance report form online for dentists to fill out and submit to KCIW. KCIW is working on procedures to receive and track the one-time compliance reports as well as develop a certificate to issue to dentists that have submitted a complete one-time compliance report as confirmation and recognition of their compliance.
