INTRODUCTION

The proposed RTZ Industrial, LLC is located along the southerly side of Interstate 70 approximately 7.5 miles easterly of the DeBeque interchange. See Project Location Map, Figure 1.

The property is a gently sloping, triangle-shaped tract of some 103 acres that is bounded on the north by Interstate Highway 70, the Union Pacific Railroad and State Highway 6 and 24. On the east side of the property is County Road 300, across which is a currently operating sand and gravel operation. To the southwest of the proposed operation is the Colorado River. The proposed site has received some limited sand and gravel extraction in the past and was permitted as the L.G. Everist Pit. The property is generally at an elevation of 5000 feet above sea level.

Although the site development has been divided into three phases, reclamation will occur more or less continuously as mining is completed. This will accomplish three main goals:

1. Begins reclamation on any one area as early as is practical 2. Reduces potential for fugitive dust emissions 3. Reduces material handling costs

As overburden and topsoil are removed for mining from one area they can be placed in areas that are being reclaimed, reducing the need for material stockpiles.

The proposed operation is intended to mine, crush and screen sand and gravel from the alluvial materials adjacent to the Colorado River. The operation will process approximately 150,000 tons of material per year, a portion of which will be sold and hauled offsite. Depending on the market for the products sold, the operation will have and expected life of ten years. As sand and gravel pits normally go, this operation will be a relatively small one. There will be no asphalt or concrete mixing operations involved. Excavators, front-end loaders, strippers and off-road haul vehicles will be the primary means of mining and moving materials to and from the crushing and screening plants. The specific types and capacities of the equipment are provided in the Emissions Permit.

Although the mining plan divides the site into three phases, reclamation will occur continuously as mining is completed. This will accomplish five main goals:

Begins reclamation on any one area as early as is practical to do so, Reduces visual impacts of the mining operations, Reduces potential for fugitive dust emissions, Reduces material handling costs, and Increases the potential for reduced bonding requirements. As overburden and topsoil are removed for mining from one area they can be placed in areas that are being reclaimed, reducing the need for material stockpiles. The reclamation will include two ponds as a water feature and residential lots. Mining and Reclamation plans are included as Appendices C and D, respectively.

The adjacent land uses are primarily industrial and transportation related uses. A sand and gravel operation similar to the proposed RTZ operation is currently in operation on the east side of the RTZ tract. Highways, railroad tracks and industrial storage/staging area for gas development border the property to the north. It is believed that the proposed land use will not significantly impact those adjacent areas.

The south side of the property is bordered by the Colorado River. A 200 foot wide buffer zone along the river has been built into the mining plan so that there will be no visual impact from river level. The north side of the property is bordered by the Railroad and has a 200 foot offset from the pit boundary to the Railroad Right of Way.

Appendix E is a Stormwater Management Plan which addresses the Construction Dewatering Plan, Stormwater Runoff Plan, Best Management Practices ang Materials Handling and Spill Prevention details how potential pollutants will be kept from entering state waters. In addition, Appendix F contains the NPDES permit which further specifies how water pollution will be prevented at the RTZ site.

MAJOR BASINS:

The property is affected by the 100 year floodplain of the Colorado River as established by the Corps of Engineers. The floodplain and floodway, as determined by the Corps of Engineers drawings dated December 1982, and found on the Garfield County website, are shown on Figure 4, Floodplain Map.

OFFSITE DRAINAGE BASINS

The three drainage basins shown on Figure 2, Basin Map, could affect the site. Basin A crosses the interstate and the railroad to enter the site near the westerly end. The existing channel for that basin is being preserved and thus the runoff from Basing A will be routed through the site and on to the Colorado River. The other two basins, B & C, also cross under the interstate and the railroad, but follow a route that cuts across the extreme northeast corner of the site and then continues southeasterly on to the river. No on-site culverts are necessary, so calculations showing the channel size necessary to convey the 100 year flow are enclosed in the calculations appendix.

The runoff calculations for each basin are also included in the appendix.

IRRIGATION DITCHES

No irrigation ditches affect this property. HYDROLOGY

The hydrologic methods for the minor basins in this study are as outlined in the Soil Conservation Service publication "Procedures for Determining Peak Flows in Colorado" (1980). Peak flows in this area will be primarily rainfall derived since the whole site as well as most of the offsite basin are below 8000 feet in elevation. Therefore, the storm drainage system will be more than adequate to handle spring snowmelt runoff, as it typically has much lower peaks, even though of longer duration. The precipitation amounts for the 25 and 100 year, 24 hour storms were taken from the NOAA Atlas 2, Volume 4, published by the National Weather Bureau (copies with the site location plotted are included in the Calculations Appendix). Runoff calculations are included in the Appendix, and a summary table of the results is provided at the end of this text.

The hydrologic characteristics were based on information from the Soil Survey of Rifle, Colorado with parts of Garfield and Mesa Counties. The typical Hydrologic Soil Group was "D" for Basins A, and Basin B. A general Curve Number of 89 was used for Range Ground in Poor Condition.

ON SITE DRAINAGE

On site drainage patterns are shown on Figure 4, the Drainage Plan. The estimated flows that could affect the proposed residential lots are minor and will be short lived as well as diffuse. Since the flows will be relatively shallow and diffuse, the possible damage to buildings can be mitigated with a proper site grading plan. This could be no more elaborate than a berm or benn/ditch combination on the uphill side of each building, or across the top of the whole building envelope, or by elevating the finished floor sufficiently to allow flow away from the building in all directions. Note that the existing and proposed building sites are amply spaced to allow storm runoff flows to be diverted around each site without significantly affecting adjoining sites.

Detention is not proposed for this development because the runoff can be conveyed directly to the river without affecting any other properties.

EROSION CONTROL

See NPDES permit for information on erosion control. The plan and details of that plan are included as an attachment to the general application. Proper drainage of Basin A will require that the existing 9'x12' and 8'x8' box culverts on the Northwest edge of the subject parcel be properly maintained and undisturbed by the mine plan construction. The project dewatering pond will discharge to the unnamed drainage as illustrated in the Stormwater management plan.

Drainage of Basin B will be maintained by the usage of the existing drainage ditch on the eastern boundary of the subject parcel. An existing 48 inch CMP diverts runoff from Basin B into an open ditch across the subject parcel. This open ditch will be maintained for the duration of the project. See the attached Figure 4 for specific site details. SUMMARY

Impacts to proposed building areas due to on and off site runoff can be mitigated by routing flows through the site with reasonable care. Additional storm runoff generated from the development of the RTZ Industrial, LLC will be insignificant due to the large lot areas and small impervious areas in relation to the lot size. .... 0..

Description

Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms.

The soils in the Un~ed States are assigned to four groups (A, B, C, and D) and three dual classes (AID, BID, and CID). The groups are defined as follows:

Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission.

Group B. Soils having a moderate infillration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefty of soils having a layer that Impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission.

Group D. Soils having a very slow inflftration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission.

If a soil is assigned to a dual hydrologic group (AID, BID, or CID), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. Rating Options

Aggregation Method: Dominant Condition

Aggregation is the process by which a set of component attribute values is reduced to a single value that represents the map unit as a whole.

A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not.

For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Condition" first groups like attribute values for the components in a map unit. For each group, percent composition is set to the sum of the percent composition of all components participating in thai group. These . groups now represent "conditions" rather than components. The attribute value associated with the group with the highest cumulative percent composition is returned. If more than one group shares the highest cumulative percent composition, the corresponding "tie-break" rule determines which value should be returned. The "tie-break" rule indicates whether the lower or higher group value should be returned in the case of a percent composition tie.

The result returned by this aggregation method represents the dominant condition throughout the map unit only when no tie has occurred. Component Percent Cutoff: None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. Tie-break Rule: Lower The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected In the event of a percent composition tie.

MINING PLAN Division of Reclamation Mining & Safety Pennit Application

RTZ INDUSTRIAL SAND & GRAVEL MINING OPERATION GARFIELD COUNTY, COLORADO

6.4.1 EXHIBIT D- Mining Plan

Overview The RTZ Industrial wishes to include 130.558 acres in the permit boundary, of which approximately 40.7 acres will be mined. Accessory facilities, such as an office, are incorporated into this Mining Plan (see Exhibit 8).

The reclamation of the property will be done concurrently with mining as mmmg progresses generally north and west. For planning purposes, the market for coliStruction materials from the proposed resource is 150,000 tons per year.

Description of Overburden. Deposit and Underlying Stratum Topsoil on the proposed reclamation permit site is highly variable, consisting of six feet c, of soil in some reaches of the site up to twelve feet of topsoil cover in other locations. The alluvial deposit consists of sand and natural gravel, as well as larger unconsolidated stone material and sand and gravel with traces of shale. Other than topsoil the site is level with only overburden covering the deposit. Phase I - 14.7 Acres Phase II - 9.5 Acres Phase III- 16.5 Acres

Mining Methods The proposed method of mining is surface extraction, typical of shallow alluvial deposits. Due to the presence of groundwater in the deposit, dewatering, as detailed below, is indicated to facilitate the efficient recovery of sand and gravel. Mining will progress in three phases.

Prior to commencement of production mining, topsoil will be stripped prior to mining in each phase. Topsoil and overburden will be stored outside the pit area inside the gravel pit boundary. The overburden storage area is located on the southwest portion of the parcel. This portion of the parcel will be used for storage of overburden only and will reduce the amount of transport of overburden.

Construction materials will be extracted and moved on-site with excavators, front-end loaders, strippers and off-road haul vehicles. The mining limit for the project will be at least 25 feet from utility easements in the southeast section of the parcel and 50 feet from Division of Reclamation Mining & Safety Permn Application county road and railroad right-of-way. The mining limits of the southern boundary of the parcel will be at least 200 feet from the Colorado River. These setbacks ensure the stability of the structures in the vicinity throughout the period of mining and reclamation.

Phased Mining and Processing Phase 1 commences with topsoil and overburden stripping as needed and moved to the overburden storage location. Mining will be initiated at the southeast corner of the Phase 1 mining area, creating a sump area for dewatering operations. The sump area is intended to retain pumped water for dust control and eventual discharge through outfall 001 and for controlled re-distribution to wetland areas to maintain soil moisture. The direction of mining in Phase I will generally move north and west.

The processing plant, including screening and crushers to be used during mining in Phase I and 2 will be located in the northeast section of Phase 3 mining area as shown on the Mining Plan. (Exhibit 8). Reclamation will begin in areas within Phase 1 within one year of the completion of this phase of mining.

Mining in Phase 2 will begin with stripping and stockpiling of topsoil and overburden as needed in Phase 1. The overburden will be used to as reclamation of Phase I. The mining will start in the southeast corner of the Phase 2 mining area.

After the completion of Phase 2 and prior to the mining of Phase 3 the excess overburden and top soil will be removed from Phase 3 and the processing plant, including screening and crushers will be used in Phase 2 for the mining of materials in Phase 3.

The mining of Phase 3 will continue with the stripping of topsoil and overburden from Phase 3. The mining will begin in the southeast corner of Phase 3 and move northwest. The Phase 3 is the final section of the pit area to be mined and reclamation will begin within one year of completing mining in this phase.

The processing plant will be moved off-site, allowing for the efficient recovery of all sand and gravel reserves within the permit area.

Mining Slopes The operator will not be limited to mining to approximate reclamation slopes in the event slopes in the event that backfill material is generated in sufficient quanitites to facilitate recovery of construction materials within the cross-section of the slope to the pit bottom. Mining to near-vertical slopes will be permitted where backfill material are available for reasonably contemporaneous placement along mined slopes.

Final sculpting of reclamation slopes of 3:1/2:1, in accordance with Construction Materials Rule 3.1.5(7), may occur at the time of mining or with concurrent reclamation.

Earthmoving Operations and Maximum Disturbance Division of Reclamation Mining & Safety Permit AppUcatlon

The vegetation and plant growth medium within pit boundary will be cleared and salvaged in the penni! boundary. Topsoil, as available, can be used to construct 6-foot screening benns in determined locations.

Standard equipment, including excavators, backhoes, loaders and haul trucks will be used in earthmoving operations at the RTZ Industrial Gravel Pit.

Site disturbance will be minimized through the use of phasing plan and the reclamation plan.

Dewatering The RTZ Gravel Pit will be equipped with pumps to allow for dry-mining. Water impacts associated with dry-mining have been addressed in Exhibit G and the water right decree.

The RTZ Gravel Pit will pump water to the detention pond located on the west end of the project for discharge to the existing stream and sample point 00 I. This will allow for a dry pit area and give access to the pit floor. If only partial dewatering is obtained; mining methods will be adapted accordingly. The wet pit run will be removed with a track hoe and set on the pre-mining area for temporary drying and removed with a loader. This two stage mining will be used where groundwater pumping is limited due to on or off-site constraints.

(' ; Primary and Secondary Commodities The primary commodities to be mined are sand and gravel. These are expected to be used for road bed material and oil and gas pads. There is no secondary commodity.

Incidental Products There should be no incidental products expected from this operation

Explosives Explosives are not planned to be used in this proposed operation. i-'! . ~<' ' .. ' . ; ·'- ..

RECLAIMATION PLAN Division of Reclamation Mining & Safety Permit Application

RTZ INDUSTRIAL SAND & GRAVEL MINING OPERATION GARFIELD COUNTY, COLORADO

6.4.1 EXHIBIT E- Reclamation Plan

Introduction

The RTZ Industrial mining plan proposes to use 131.558 acres for the gravel mining activities, of which 40.7 acres will actually be mined. The mining and reclamation is to proceed in three phases with reclamation of each phase following closely behind each mining phase. All of the affected land is to be reclaimed. Reclamation will include (1) contouring and stabilization of slopes, (2) placement of topsoil and soil amendments, (3) seeding and planting and (4) follow-up monitoring and management to ensure adequate soil cover and noxious weed suppression (See attached Exhibit E, Reclamation Plan).

Topsoil Preservation

( Topsoil will be removed prior to mining each phase and will be stockpiled in mounds on the western end of the property. A temporary seed mixture, following the recommendations of the Natural Resource Conservation Service (NRCA) (See attached NRCA seed recommendations), will be applied by broadcasting to help stabilize the soil against wind and water erosion. When broadcast seeding is used the seeding rate will be doubled per NRCA recommendations. Certified weed free hay or straw will be used for mulch, except where the slope exceeds 10 percent. In those instances an agronomy blanket is to be used.

Final Contouring

The Reclamation Plan Map, Exhibit F, shows the proposed final contours. Per Construction Materials Rule 3.1.5 (7), final slopes will be no greater than 3:1 (H:V) for 5 feet above and ten feet below the water table. Most other slopes will be 2:1. The base of the pit is expected to be at or near bedrock, which in most areas will be approximately 24 feet below ground surface.

Final grading is to be accomplished by the excavation equipment onsite. All grading is to be completed in a manner to control erosion and siltation of the affected lands. All backfilling and grading shall be completed as soon as feasible after the mining process. Areas that are to be backfilled will be compacted to provide stable slopes. If farm equipment is to be used for topsoil mixing and for planting, final contours will be compatible with these activities. Division of Reclamation Mining & Safety Permit Application

Topsoil Redistribution

The fall season is the best planting time to provide optimum plant survival. Topsoil will be taken from the stockpile and redistributed to disturbed areas after slope stabilization has occurred and in line with the planting seasons. Three to six inches of topsoil and soil amendments will be mixed using a disk harrow or other such equipment.

Seeding and Planting

Seeding of the NRCS-recommended dry land grasses will be undertaken during prime planting seasons, October 15 through April 30. Seed mixtures recommended by the NRCS, as stated in the attached letter, will be used. The letter includes recommendations for rates and methods for seeding and planting. These recommendations will be followed as closely as possible to provide the best conditions for maximum plant survival rates.

Seeding of the larger areas will be completed during the first prime planting season following the completion of mining, contouring and topsoiling of each phase of the project. Planting may proceed prior to the end a phase of the project if contouring and topsoiling are completed and it is in line with sound engineering practices. Seeding will be accompanied by straw or hay mulch or its equivalent. ( Planting will be accomplished using a seed drill using a drill spacing of 7 - 10 inches, Planting depth will be Y. to Y. inch. If the seed is broadcast the seed coverage will be twice that shown in the NRCS recommendations and mulched, if needed.

Follow-up Monitoring and Management

Management of the reclaimed area will proceed according to NRCS guidelines. RTZ will monitor the plant growth progress and add soil amendments, including fertilizer, if needed. Grasses will be mowed for at least the first two years after reclamation of each phase to establish regenerating stands of grasses and to control weed infestation.

Noxious Weed Control

RTZ Industrial will control noxious weeds using the recommendations of the Colorado Noxious Weed Management Act and the Garfield County Vegetation Management Department. Weeds listed by Garfield County as noxious are shown below:

Common Name Scientific Name Leafy Spurge (Euphorbia esula) Russian Knapweed (Acroptilon repens) Division of Redamation Mining & Safety Pennlt Application

(970) 945-5700 INTRODUCTION

The proposed construction of the RTZ Gravel Pit will take place on a 130 acre tract of land located 4.5 miles west of Parachute, Colorado at the intersection of Highway 6 & 24 and Stone Quarry Road. The site is bordered by the Union Pacific Rail Road line and Interstate 70 to the north, to the east by an existing gravel pit operation, to the west by undeveloped land, and to the south by the Colorado River.

The project will initially involve the development of the gravel pit, Including the removal and stockpile of topsoil and overburden, clearing and grubbing the area for crusher machinery and offices, and reclamation of the pit after each phase has been fully mined. It is anticipated that reclamation will entail open water ponds, and a future development to the site may occur, but these activities are not formally proposed at this time.

The implementation of this storm water management plan shall begin prior to any construction. This plan covers the mitigation of the adverse effects of storm water runoff during construction, and gravel mining and crushing operations. The owner, contractor and subcontractors will be responsible for the construction of the infrastructure and protection of adjacent water courses.

Construction Sequence

The date for beginning construction activities is estimated to be March 2009. Implementation of the storm water management plan is required to be in place prior to initiating construction activities. The storm water management sequence is the installation of the perimeter sediment controls such as sediment control fencing, and erosion logs and/or straw bales, followed by clearing and grubbing. The site will be developed in three phases. The phases will consist of 14.7 acres for Phase I, 9.5 acres for Phase II, 16.5 acres for Phase Ill. This will limit the disturbed area to one third of the site at a time. As each phase has been fully developed, it will be reclaimed and revegitated before the next phase proceeds. The intent of this storm water management plan is to cover the development and operations of the three phases for the crushing activities and reclamation of the site. The construction phasing can be seen on the attached construction phasing map. (Fig. 1)

The stabilization methods will be further described below.

Existing Conditions

The site can be broken into three parts. The upland area is dominated by scattered greasewood shrub lands. This area includes the railroad right-of-way and will not be affected by the mining operations.

The second part is the main area that will be mined and includes the previously disturbed and excavated borrow pits. This area also has infrequent rabbit brush and widely scattered saltbrush. As a result of the prior disturbance and the high salinity of this area it currently has a ground cover of about 20% to 30%. The third area is the cottonwood riparian woodlands immediately adjacent to the Colorado River which also has tamarisk, Russian olive, and small patches of cattaiL Grasses in this area were dominated by saltgrass.

A wildlife study conducted by Rocky Mountain Ecological Services has identified three wetlands areas on the proposed property. These wetlands are located along the county road and the Colorado River. The gravel pit boundary has been adjusted to exclude the wetlands.

Proposed Conditions

As previously described, the proposed construction will consist of the development, operation, and reclamation of a gravel mining and crushing operation. The proposed reclaimed site will include two new ponds. (Attach reclamation plan) All other disturbed areas of the site will be revegitated to stabilize the site in the interim until the site obtains approval for a residential development. The site will be revegitated with a native seed mix in accordance with the attached seeding plan.

CONSTRUCTION DEWATERING PLAN

Dewatering of the gravel pit is anticipated due to shallow water table and the proximity of the gravel pit to the Colorado River. A construction dewatering permit has been submitted to the Colorado Department of Public Health and the Environment. A lined, 300ft. by 100ft. detention pond will be constructed on the east side of the unnamed intermittent stream as identified on the attached site map. As each phase of the gravel pit is developed, a sump will be constructed and the water will be pumped to the detention pond. The water leaving the detention pond will pass through a Parshall flume with a continuous data logger to record the water leaving the plant. The water will then flow through a series of check dams along the unnamed intermittent steam to the Colorado River.

STORMWATER RUNOFF- DRAINAGE PLAN

Stormwater runoff from this site will be, in general, unconcentrated sheet flow. The sheet flow off of the stripped land and the stockpiles will be channeled into ditches to minimize erosion. Because of the natural slope of the site, the storm water will be channeled into three outfall areas. These three areas are: the bar ditch alongside County Road 300, the unnamed Intermittent stream on the east side of Phase II, and the unnamed intermittent stream south of the topsoil stockpile. The three outfalls will have check dams and straw bale BMP's to minimize sediment and erosion before the storm water reaches the Colorado River. A silt fence will be required along the southern edge of the gravel pit near the Colorado River to minimize sediment from entering the river from the low areas of the site.

BEST MANAGEMENT PRACTICES (BMPs)

The following describes the site management procedures that will be implemented for the RTZ Gravel Pit site in accordance with typical Best Management Practices (BMP's). During construction activities and until vegetation can be established, temporary BMP's will be utilized to minimize the effects of sediment erosion and to manage storm water. The stripping of topsoil and overburden from the site will produce large stockpiles on the site. The size of these stockpiles will be constantly changing as more material is removed from the site and deposited at the stockpile. For this reason a perimeter ditch will be a better choice than silt fence. The perimeter ditch can easily be moved and maintained as the stockpiles are moved and changed with the equipment available at the site. A ditch will be placed around the perimeter of the stockpiles to gather runoff from storm events and channel it to a detention pond. The detention pond will allow the sediment to fall out of the storm water before it enters the intermittent stream. The sides of the stockpiles will be tracked with a dozer to minimize sheet flow off the sides of the stockpiles.

Erosion control logs or certified weed free straw bales will be placed at intervals of approximately 100ft in major drainage channels/roadside ditches and at intervals of approximately 50ft in minor drainage channels leading from culverts. They will also be placed at the end of all swales before the swales outfall into the major drainage. These controls should be sufficient to mitigate the sediment discharged Into the existing system.

Sediment and mud shall be prevented from leaving the construction site by immediate placement of a vehicle tracking pad at entrance. The contractor is responsible for cleaning and general upkeep of existing public roads used for access. In the interim condition water trucks should be maintained and utilized onsite for the duration of the construction period to minimize potential fugitive dust caused by mining activities as an effective dust control measure.

Good housekeeping BMPs should be followed throughout the entire life of the project. These include the following:

-refuse receptacles should be regularly emptied and equipped with lids,

-keeping machinery in good operating condition to prevent leakage.

-apply appropriate (not excessive} amounts of fertilizer to the landscaping.

-scheduled maintenance of BMPs and cleaning of check dams, vehicle tracking pad, and silt fence.

Other housekeeping practices should include general site cleanliness and proper training of employees. Seeding of disturbed areas is needed after the completion of construction. The seeding may be only temporary if it is in areas that will contain pavement or buildings in the future.

MATERIAL HANDLING AND SPILL PREVENTION

If fuel or oil for construction machinery is present on the site, materials should be stored and handled in covered areas to prevent contact with stormwater, and chemicals should be stored within berms or secondary containment devices to prevent leaks and spills from entering stormwater runoff. Cleaning and fueling of machinery should be done during dry weather, if possible. Washing of concrete trucks and other equipment into the storm drainage system is prohibited. Spills or accidents shall be immediately reported to the SWMPAdministrator and depending on the nature of the spill involved, the Colorado Department of Health, downstream users, or other agencies may need to be notified. FINAL STABALIZATION

Once construction activities are completed for each phase, restoration and final stabilization of the disturbed areas will begin. Within one growing season of the project completion, uniform vegetative site coverage shall be equal to or greater than 70% of the pre-disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed, to be considered stabilized. When the site is determined to have reached the final stabilization stage, temporary erosion control measures can be removed.

INSPECTION AND MAINTENANCE

A thorough inspection and maintenance of the storm water management system is required every 14 days and after any precipitation or snowmelt event that causes surface runoff. The permit will describe the inspection procedures to follow. As part of the inspection, a logbook needs to be kept. The following information should be included in the logbook (per "Construction Guidance Document: Preparing a Storm Water Management Plan," Colorado Department of Public Health & Environment, 7/94):

-records of any spills, leaks, or overflows, including time, date and weather condition,

-implementation of specific items in SWMP,

·events involving materials handling and storage,

- contacts with regulatory agencies

-maintenance and repair of storm water management controls,

-preventive maintenance activities,

-inspection activities and

-dated photographs.

RETENTION OF RECORDS

The permittee shall retain a copy of the Storm Water Management Plan required by this permit at the construction site from the date of project initiation to the date of final stabilization.

The permittee shall retain copies of the Storm Water Management Plan and all reports required by the permit and records of all data used to complete this application for a period of at least three years from the date affinal stabilization. AITACHMENTS LEGAL DESCRIPTION RTZ INDUSTRIAL

NATIONAL POLLUTION DISCHAGE ELIMINATION SYSTEM IV ATER QUALITY CONTROL DIVISION COWRADO DISCHARGE PERMIT SYSTEM APPLICATION DISCHARGES ASSOCIATED WITH SAND AND GRAVEL PRODUCTION OPERATIONS FOR STORMWATERrutd PROCESS WATER (AND OTHER NONMETALLIC MINERALS EXCEPT FUEL)

This application is for use by all industrial process and/or stormwatcrdischargers engaged in sand and gravel production operations, and other nonmetallic minerals (except fuels). This application is for both active and inactive mining operations and concrete and asphalt batch plants ot the mine. This application is for coverage under a general or individual penn it. This fonn may be reproduced. For infonnation on electronic copies, please contact the Permits and Enforcement Section at (303) 692·3500. It is suggested that the applicant contact the Division of Mining and Geology at the Colomdo Department of Natural Resources, concerning reclamation rules and regulations at (303) 866-3567.

WATER RIGHTS

The State Engineers Office (SEQ) has indicated that any discharge that does not return water directly to surface waters (i.e. land application, rapid infiltration basins, etc.) has the potential for material injury to a water right. As a result, the SEQ needs to detennine that material injury to a water right will not occur from such activities. To make this judgement. the SEO requests that a copy of all documentation demonstrating that the requirements of Colorado water law have been met, be submitted to their office for review. The submittal should be made as soon as possible to the following address:

Colorado Division of Water Resources 1313 Shonnan St. Rm 818 Denver, Colorado 80203

Should there be any questions on the issue of water rights, the SEO can be contacted at (303) 866-3581. It is important to understand that any COPS permit issued by the Division does not constitute a water rjght. Issuance of n COPS permit docs not negate the need to also have the necessary water righls in place. lt is also impommt to understand that even if the activity has an existing COPS penn it, there is no guarantee that the proper water rights are in place.

A-1 APPENDIX B • STORMWATER MANAGEMENT PLAN (SWMP) 9/97/sg

In this doctuncn~ the text in bold italics is quoted directly from the Sand and Gravel general permit. The text in straight type is provided as guidance in the preparation of your SWMP.

The requirement to develop a Stonnwater Management Plan (SWMP) prior to application for tl1e general permit applies to all facilities. The applicant shall develop a SWMP for their facility, and certify in Item 8 of the application that it has been completed. The SWMP shall be prepared in accordance with good engineering pmctices. (The plan need not be completed by a registered engineer.)

The plan shall identify potential sources of pollution (including sediment) which may reasonably be expected to affect the quality ofstormwater discharges associated with the mining activity. In addition, the plan shall describe and ensure the implementation of Best Management Practices (BMPs) which will be used to reduce the pollutants in stonnwater discharges associated with mining activity. BMPs are defined as physical, structural, and/or managerial practices that, when used singly or in combination. prevent or reduce pollution of water.

Mining operations must certify the completion of their SWMP, as described in this document. Implementation of the plan will be required at the time that coverage under the general pennit begins. The Division reserves the right to request and review the plans, and to require additional measures to prevent and control fX>llution, as needed.

When preparing your plan, make sure to address each item. If it is not applicable to your site, briefly e:.:plain why. A simple ''Not Applicableu is not enough. Also note that the SWMP should include any existing stormwater controls at your site, not just new or proposed ones. Take full credil for what you are already doing.

The SWMP shall include the following items, at a minimum:

I. SiteMap

Tile piau sltall provide a site map or maps which indicate at a minimum:

Atlining site boundaries Access a11d /tau! roads Stormwater outfalls and tm outline ofthe drainage area ofeach stormwater outfall An estimate oftile direction offlow Materit1/s lla11dling areas Each existing structural cmrtrol measure to reduce pollutm1ts in stormwater runoff Areas usellfor storage or disposal ofoverburden, materials, soils or wastes Areas used for mi11eral mi/li11g anti processing Spri11gs, streams, wetla11ds ami other surface waters Locatio11 vfmine draitmge or ally otfler process water Bowulary oftributary area til at is subject to effluent limitations Date the map was prepared

1l1e drainage areas shown should include the pottions of the site where industrial activities occur, as well as those portions contributing stonnwatcr that mixes with run ofT from the industrial area. Therefore, the entire drainage area where industrial activities occur must usually be included.

Aside from mining, indusllial activities con include equipment washing, materials storage) vehicle maintenance or fueling, incineration, waste treatment, storage or disposal, shipping/loading/unloading, etc. You do not need to include industrial activities which only take p\nce indoors, unless there is some part or aspect of the activity with which stonnwater could come in contact. For example, ifall vehicle maintenance is done indoors, but vehicle storage Ol" fueling is outside, the vehicle storage or fueling urea must be addressed. It is a good idea to s1nrt with a portion of the USGS (U.S. Geological Smvey) quadmngle map showing tl1e site. These nre available and easily obtainable for the entire state; they show a large amount of information for very linle effort. You can then use the USGS map as a guide for preparing your site map, which will be more detailed. Regardless ofthe source of the bese map, the site map needs to be of suitable scale to show the industrial portion ofthe facility and the features within it .... Locations of stQimwater outfalls: If the site has a stonnwater drainage system, the location of outfalls is a simple task. Indicate on the map where pipeline outfalls are, as well as the general layout of the drainage system such as inlets, grates, pipelines, etc. Jfstormwater is conveyed over land without a developed storm drainage system, the points where runoff collects and runs off must be located. ~ Drainage basins for each outfall: Field inspection can usually accomplish this task with acceptable accuracy. Look for high areas such as crests of parking lots, road~ ete- which would fonn the division bet\veen dminages. Gullies and swales are indicators ofstonnwater flow direction. Obviously, if runoff is observed during a stonn, most uncertainties can be eliminated. ~ Surface water bodies (including dl)' water courses): Mark on the site map any surface water bodies, including lakes, streams, springs, wetlands, detenlion ponds, roadside or i1rigation ditches, etc. These do not necessarily need to be within the facility, but may be adjacent to it or impacted by stonnwater runoff. Also include any existing storm sewers . ... Existing structural control measures to reduce stormwater pollution: Show on the map the location of any structural stonnwater pollution control measures, such as detention JXJnds, diversion ditches, covered material storage areas, fuel farm secondary containment structures, etc.

In addition, there are several other features which could be included to make the SWMP a more comprehensive and usable plan. For example, later sections ofthe SWMP will include requirements for spill prevention procedu~ which can include a site map showing \vhcre materials are stored. By including the follo\ving items on the site map, all information would be in one place on a single base map.

~ Materials hondling and loading areas .... Materials storage areas ~ Paved and unpaved areas (for hydrologic assessments)

2. Description of Potential Pollutant Sources/Materialluventory

Tile piau shall provide a tlescription ofall potential sources (activities and materials) wlzicll may reasonably be expectetlto adtl pollutants to stornnvater discharges. Such sources may iuclude !raul roads, equlpmellt storage aud malntetwnce areas,ftiel storage areas, etc.

lu en eft case where stormwater pollution potential ex.ists, appropriate preve11tlve measures must be taken and documeutetl.

This section of the SWMP summarizes the existing potential for stmmwater contamination at the site. It is a narrative description which slates what is stored, where it is stored, how it is used, what has been used, etc. These can include such pollutants as fuels, oils, detergents, pesticides, herbicides, fertilizers, etc.

3. Stormwater Quality Controls

6acfl mining site covered by tills plfm slta/1 develop 11 description ofstormwafer quality controls appropriate for tit at site, and implement Sllclt controls. Tl1e appropriateness and priorities ofcontrols in tile plan shall reflect ltlentijietf potential sources of pollutants at tlte site. The description ofstormwater quality controls sfla/1 address the following miuimum components, including a scltedulefor implementing such co11trols:

This section of the SWMP, when completed, will spell out what the facility is doing to conl.rol stomnvater pollution, what the facility will do in the future, when Best Management Practices (S:MPs) will be implemented, and who at the facility is responsible for the plan.

a) SWM P Administrator- Tile SWMP sir all identify a specific individual or Individuals wltltinlhe mining orgmzizatiou wfto is responsible for developing the SWMP ami assisting tile mine operator lu its implementation, maintenance, and revision. APPENDIX A· SWMP (cont.) Page B-3

The SWMP Administro1or becomes the contact for all SWMP-related issues and is the person responsible for its accuracy, completeness, and implementation. Therefore, the SWMP Administrator should be a person in an authoritative position. Larger facilities may want to develop a "S\VMP team" in order to share the responsibilities and generate greater awareness and participation. h) Materiql.v Handling qlldSnlU Prevention- Where materials Call impact stormwater runoff, BMPs that reduce lite potential for cmztamlnation sit all be described. For example, materials slro11/il be stored and lraml/ed ill covered areas whenever possible to prevent contact wlt/1 stormwater; fitels and other cltemfcals should be stored within berms or secondary colltalnment devices to prevent leaks and spills from entering stormwater runoff.

When selecting BMPs, the most important ones to evaluate first are those which limit the source oflhe pollutant. It is much more efficient, from both a cost and environmental standpoint, to prevent the pollution in the first place than to clean up contwninated stonnwater. For example, a BMP requiring that any vehicle maintenance that involves fluid exchange must take place indoors, results in the removal of a pollutant source {i.e., oillhydrnulic fluids) from possible contact with stOJmwater.

Good housekeeping measures, such as cleaning and maintenanre schedules, trnsh disposal and collection practices, giUunds maintenance, etc., can be included here.

c) Erosion a11d Se

BMPs can describe a wide range of management procedures, schedules of activities, prohibitions or practices and other manngeinent practices. BMPs can include operating procedures, trealment requirements and practices to control plant site runoff, drainage from raw materials storage, spills or leaks. Nonstructural BMPs are mainly definitions of opemtional or managerial techniques. Structural BMPs include physical processes ranging from diversion structures to oil/water separators to retention ponds.

The BMPs selected are up to the judgment ofthe individual permittee. However, it is important to note that a fully implemented SWMP will constitute compliance with Best Available Technology (BA 1) and Best Conventional Technology (BCT), as mandated under the Federal Clean Water Act. This means that, in order 1o comply with your pe1mit, the appropriate measures must be taken in keeping with the pollutant(s) involved and the risk potential at U1e facility.

d) ldentificqtion ofDisclwqes other than Slnnmvater- Tire stonmvater C01l'I'C!J1ance system 011 tlze site sha{{ be evaluatetlfor tile preseuce oftllsclwrges oilier tllan stormwater, such as mine drainage, spoil springs, sanitary waste, or process water of any kind.

In other words. only stonnwater can be conveyed by the stonnwater drainage system. Examples of JX.l1entint illicit connections include floor drains and toilets in maintenance buildings, chemical stomgc buildings, etc. There are several methods of dete1mining whether or not illicit connections exisL Acceptable procedures include dty weather obseJvations ofoutfalls or other appropriate locations, analysis nnd validation ofaccurnte piping schematics, dye tests, etc.

Note- if illicit connections are discovered, corrective measures must be taken.
