COVER LETTER: 03/04/11 On November 8th, 2010 the Garfield County Board of County Commissioners (BOCC) approved the proposed expansion of the Western Slope Aggregate gravel pit (WSA) along with conditions of approval that were supplied by the neighboring Wooden Deer HOA (WD HOA). The purpose of this application is to request that the Board of County Commissioners amend the existing approve the same application with the exception of a single condition. Item #27 (As approved in resolution 2011-10 ) of the conditions submitted by WD HOA contained language that reduced the overall volume of the application by 72% as well as placed a 20 year time limit on expansion area and the existing 1981 Special Use Permit area, which contained no time limit. WSA is also currently collaborating with WD HOA to reach a mutually agreed upon set of conditions that omits item #27 as well as a revised reclamation and landscape plan that more specifically meets the future expectations and needs of Wooden Deer and surrounding communities. We respectfully request that the BOCC approve the application without condition #27, or amend the existing approval to delete this item. 0304 Highway 133 • Carbondale, Colorado 81623 • (970) 963-9424 • • • INTRODUCTION The existing Blue Pit is located approximately 2.5 miles east of Carbondale, CO on Highway 82. The Blue Pit is separated from the Roaring Fork River Valley by an 80' tall natural slope which remains after removing the gravel from an elevated alluvial terrace. Western SIope Aggregate has a lease with the landowner of parcels 2393-254-00-265 and 2393-254-00-285 which allows them to conduct mining operations north of this slope. The gravel deposit which is being mined was deposited by the Roaring Fork River and is greater than 100 feet thick. The groundwater level limits the mining of the deposit at approximately 90 feet deep in the expansion area and 60 feet in current permit area. The groundwater surface is estimated from the existing excavation and by exploration drilling conducted in the area. The site has been mined since 1981 under the state Reclamation Permit # M-1981-207. Western Slope Aggregate has operated the site since 1991. The site expanded to an annual production rate of approximately 450,000 tons per year. The existing permit area is 82.70 acres; approximately 25 acres is still able to be mined. This application in 2010 is to allow for an expansion area of approximately 60 acres, all of which will be used for additional gravel mining. The existing reserves will be exhausted in approximately 9 years and Western Slope Aggregate wants to secure reserves further into the future. The expansion area is located directly adjacent to the existing operation and is shown the Vicinity Map which is included in Exhibit B. Since Western Slope Aggregate has operated the Blue Pit, there have been no major complaints or violations, Western Slope Aggregate realizes that there are impacts associated with the expansion of the Blue Pit, especially to the homeowners north of the pit. Through the proposed mitigation measures, mining of the expansion area will minimize impacts and provide an excellent reclamation plan for the final site.

Pre -Mining, Mine Plan and Reclamation Plan Maps These maps are included in Appendix B. 3, Existing Conditions The existing site consists of an active gravel mining operation with approximately 9 years of reserves remaining under the existing permit. Map C-1 shows the current operation as of November 2009. The pre mining land use of the expansion area is irrigated pasture. The expansion area is bordered on the south by a south facing slope that descends to Highway 82, on the west by irrigated pasture owned by Cerise, Clifford Ranch Company, on the north by irrigated pasture and rangeland that has been put into a conservation easement and on the east by a landfill owned by Harold L. Blue. Adjacent landowners to the land where the Blue pit expansion is located are shown in Exhibit G. The Basin and Spring Ditches cross the property and will continue to do so throughout mining and reclamation of the Blue Pit. There is a concrete plant on site which has a separate special use permit through Garfield County. This concrete plant is owned by Casey Concrete. 4. Mine Plan A. General Mining Plan The gravel deposit is greater than 100 feet deep in the area of the Blue Pit Expansion. The groundwater level ranges from approximately 60 feet below the surface in the current mining area and increases to 90 feet in the expansion area. Since this operation will not intercept groundwater, the operation will stay at least 2 feet above the groundwater level at all times. Excavation will be conducted with a dozer pushing the raw material to a loader, which will then load the material to the crushing plant. As the mining face moves further from the existing crushing/screening plant location, a haul truck may be used to transport the material from the mining face to the crushing/screening plant. The crushing/screening plant will produce stockpiles of different sized rnaterials. Some of the material will be hauled to the wash plant to make different products for sale as well as feedstock for the concrete plant. The gravel deposit will be mined at a slope of 1.5H:I V (67% slope). This mining slope will recover the maximum amount of gravel as well as keeping a safe slope. Since the mining depth is 90 feet in some places, benches below the existing ground level will be created during mining to promote safe recovery of the material. Table 4-502.C(1) describes the mining areas and the quantity of material that is expected to be encounter in those areas. Mining Area I is the portion of the existing permit area that is east of the Basin Ditch. Mining Area 2 is the portion of the existing permit which is west of the Basin Ditch. The remaining Mining Areas 3, 4 and 5 make up the expansion area. Mining will progress in order grinning areas. Map C-2 shows these areas. The mining sequence and depth of the deposit has been utilized to lessen the visual impacts to homes to the north. This is explained in greater detail m the Visual Impact Report. Blue Pit - February 2010 C-2 • Table 4-502.C(1) Minin Area and Quantities Mining Area Acreage Topsoil (C.Y) Overburden (C.Y.)

The Years to Complete column is based on an average annual production of 450,000 tons per year. This has been the average over the past few years but sales are always dependent on demand. Additional information on the phasing of the operation and the method of mining are included in the Visual Impact Report because it was the basis of the sequencing. The Visual Impact Report is located in Appendix G. B. Mine Facilities and Operation The mine facilities and operation will continue into the expansion area as it does now. The shop and stockpile area will remain in its current location near the access entrance until ample room is available on the pit floor. The fuel tank area will stay in its current location over the life of the pit, immediately southeast of the shop building. The wash plant and associated stockpiles is currently located north of the shop building. As mining progresses to the west, this facility will initially move to the area north of the current wash pond location north of the mining area and will eventually be moved to the pit floor. Both the intermediate and final locations are better visually than the existing location for the homes located north of the pit. Equipment parking is located east of the concrete plant and immediately south of the shop. These locations will be maintained for the life of the pit. All current facilities are shown on Map C-1. The concrete plant is permitted without an expiration date which means that it will stay at its current location after the mining operation has exhausted all its reserves. Water from the Basin Ditch will continue to be used for dust control. As the mining operation moves to the expansion area the processing equipment (crushing and screening plant) may move with the active mining face to reduce pit haul traffic. The processing equipment will be placed in a location close to the northern slope to prevent nuisances to the home owners to the north of the pit. C. Topsoil, Overburden and Wash Fines Handling An existing topsoil stockpile is located at the eastern edge of the current disturbance area, as shown on Maps C-1 and C-2. This pile contains approximately 104,000 cubic yards. This material will be used to reclaim Mining Area 1 once final grade is achieved. Mining Area 1 requires 86,000 cubic yards of topsoil for reclamation based on the restored thickness of 12 inches. The excess will be used in other areas. Blue Pit - February 2010 C-3 Additional topsoil stockpiles will be located at the temporary wash plant location as shown on Map C-2. This area will be used to temporarily store the topsoil from the expansion area that cannot be directly placed on backfilled areas, Overburden will continue to be stripped in advance of the mining operation. Its thickness varies from 2 feet to 10 feet but it is expected to average 4 feet over the entire expansion area. Since there is a significantly lesser amount of topsoil and overburden compared to gravel, the stripping will only be needed a few days per year. Topsoil will be stockpiled for the initial period until the mining operation has progressed far enough for reclamation to start. This is expected at the end of Mining Area 2. Once areas are ready for reclamation, the stripped topsoil will be directly placed in these areas. Overburden will always be directly placed because there are areas currently ready for overburden placement and this will continue until the end of mining. Wash fines are generated from the washing operation and will continue to be produced. These fines will be placed on the mining slopes along with the overburden to produce the 3H: IV slopes. The amount of material needed to reclaim the slopes to 3H:1 V is shown for each mining area on Map C-2. Currently Mining Area 1 has an excess 829,000 tons of backfill material which can be used for backfilling other areas. Import material will also be used in the reclamation process for backfilling slopes. This quantity and cost is addressed in the DBMS reclamation bond. D. Water Handling Water for this site is supplied from the Basin Ditch, Spring Ditch and a well on site. The mining operation has an approved augmentation plan for the use of the water from the Basin Ditch which is located in Appendix J. The water is used for dust suppression, material washing and concrete production. One of the challenges that Western Slope Aggregates faces at this site is mining the reserves under the Basin Ditch. Recovering these resources needs to happen in a way that will not disrupt the functionality of the ditch since this ditch supplies water users downstream. This will be accomplished by mining as close as possible to the ditch from Mining Area 1 and then mining as close as possible from Mining Area 2. In one winter, while the ditch is not running, the material beneath the Basin Ditch will be mined or moved to another area on the pit floor to allow an inverted siphon to be installed. This inverted siphon is a typical use for a ditch to cross a low point without needing a trestle. The water entering the siphon on the south side will push the water out on the north side. This siphon has been used successfully at other sites such as the Colona Pit near Montrose, where the siphon has been in full operation for years without any problems. Very little surface runoff reaches the mining operation because it is protected up gradient by the Basin and Spring Ditches. E. Schedule of Operations Mining, processing and sales will continue to operate 12 months per year. The hours of operation will be 7:00 a.m. to 8:00 p.m. Monday through Saturday with mining, processing, and sales only occurring until 6:00 p.m. Blue Pit - February 2010 C-4 F. Haul Roads and Access The site will continue to use the same haul route to Highway 82, which is a private road and is shown on Map C-2. The daily or hourly haul traffic is not increasing with the expansion of the reserves. The approved access permit with CDOT is included in Appendix C. There is an additional haul route when servicing the area to the north of the pit which only produces a very small amount of tonnage per year. This haul route uses CR 103 and CR 104 to access Crystal Spring Road and is shown on Map C-2. Additional information on the Highway 82 access is provided in Appendix C. 5. Reclamation Plan A. General Reclamation Plan As stated in the mining plan, the reining slope will be 1.5H:1V to recover the material. These slopes will be backfilled to the final reclamation slope of 3H:1V in mining areas 2, 3, 4, and 5. A justification of reasons why this slope is appropriate at this site is given in Section 7-840 Gravel Extraction Regulations Exhibit K. The reclamation slope in Mining Area 1 is currently 2.5H:1 V and will not be changed with this amendment. The material that will be used for this backfilling will be salvaged overburden, washed fines, and import fill. If backfill material is insufficient to reclaim the slopes from 1.5H:1 V to 3H:1V then the mining slope will be reduced to compensate for the lesser amount of backfill material. This scenario is not expected since Mining Area 1 has over 800,000 tons of excess fill. The more likely scenario would be that excess fill material will be available and will be placed on the pit floor to decrease the slope lengths and increase the irrigated pasture acreage of the post mine land use. The total permit area is 146.87 acres. The area to be mined is 123.59 acres. The difference of 23.28 acres will be used for topsoil stockpiling, temporary wash plant location, shop area and access road realignment. The post -mine land use acreage breakdown is shown in Table 4-502.C(2). The concrete plant wilI remain in its current location after the mining is completed. This will allow for future concrete demands to be met from this site. At that time, the aggregate needed will be imported to the site to produce concrete. Table 4-502.C(21 Post Mine Land Use Land Use Acreage Rangeland 104.07 Irrigated Pasture 29.21 Roads 5.12 Industrial 8.47 Total 146.87 B. Topsoil Replacement Topsoil has been salvaged from the existing operation and is stockpiled on the eastern portion of the existing permit area (See Map C-2). Topsoil will also be salvaged from the expansion area. Initially, topsoil will be stockpiled to the east of Mining Area 3. As the mining progresses, topsoil can be directly placed in the reclamation areas to remove the stockpile step. Topsoil will be replaced at an approximate thickness of 12 Blue Pit - February 2010 C-5 inches over the entire site. Topsoil will only be placed on areas ready for final reclamation. The temporary seed mix that has been designed for this site to reduce visual impacts will grow in overburden. C. Haul Roads and Access The haul roads that will remain after reclamation are shown on Map F (Reclamation Plan Map). These roads will be used by the landowner for access through the site as well as to the irrigated pasture on the bottom of the site. Additionally, access to the concrete plant operation will remain after final reclamation. D. Reclamation Sequencing Reclamation of the site will follow the mining operation. This contemporaneous reclamation allows for visual impact mitigation as well as limiting the size of the bond required by the Division of Reclamation, Mining and Safety. See the Cross Section Map located in Appendix G for further details on the reclamation sequencing which includes the temporary and final reclamation activities. E. Revegetation Plan As areas are mined out they will be revegetated. If the areas are in their final reclamation status, topsoil will be placed and the final seed mix will be applied. lithe area has not been backfilled; is not in its final reclamation status; and is visible to the homes north of the site, the temporary seed mix will be applied to mitigate visual impact. The three different seed mixes to be used for reclamation of the Blue Pit are as follows: Blue Pit - February 2010 C-6 Temporary Seed Mix Common Name % of mixture Drill Seed ALS/ acre Annual Ryegrass 10 5 lbs. Triticale 10 5 lbs. Oats 10 51bs. Crested Wheatgrass 10 5 lbs Smooth Brome 10 5 lbs. Slender Wheatgrass 50 25 lbs. Totals 100 50 lbs Irrigated Pasture Seed Mix Common Name Alfalfa Orchard Grass Meadow Brome Total Rangeland Seed Mix Common Name Western Wheatgrass Thickspike Wheatgrass Slender Wheatgrass Green Needlegrass Indian Ricegrass Mountain Brome Four Wing Saltbrush Rubber Rabbit Brush Total % of mixture Drill Seed ALS/ acre 44 12.0 30 8.0 26 7.0 100 27.0 % of mixture Drill Seed ALS/ acre 17 5 17 5 17 5 13 3.75 9 2.5 13 3.75 7 2 7 2 100 29 The temporary seed mix is used on areas which are not ready to be permanently reclaimed but will cover disturbed areas to lessen visual impacts to the homes to the north and to reduce wind and water erosion. F. Post Reclamation Site Drainage The Blue Pit is an elevated terrace above the Roaring Fork River Valley. There are no streams that enter the site and there will be no surface water that leaves the site after reclamation. Surface runoff from above the site is captured by the Basin Ditch and the Spring Ditch and will continue to do so after reclamation. All disturbances are graded to the pit floor which is sufficient to hold a 100 year event that drains to the permit area. Additionally, the material of the pit floor is very porous because it consists of large gravelly material. Stormwater that is encountered within the pit will infiltrate to the groundwater as it does today. The reclaimed 3H:1 V side slopes will have Blue Pit - February 2010 C-7 • stormwater catchment benches which will prevent erosion. The stormwater catchment benches will be graded to one of three grouted channels to take the water from the slope to the pit floor. All post -mining drainage features are shown on Map F (Reclamation Plan Map). See Erosion and Sedimentation Control Plan in Exhibit D for more details on the design of the ditches and grouted channels. G. Weed Control Initial Weed Treatment Program The principle existing weed locations are shown on Map C -I. The intent of the Initial Weed Treatment Program is to reduce the noxious weeds for the site to approximately 1O% of the current amount. The remaining portion will be treated through annual maintenance treatments. Weeds will be treated using the following program: The knapweed and other weeds will be treated through spraying. The areas will be sprayed in the fall to maximize potential benefit. The following spring the site will be inventoried again prior to treatment. It is anticipated that the densely infested topsoil stockpile will require 1-2 years of treatment before the knapweed is completely controlled. Once this achieved the weed plan will transition to the maintenance plan. Weed Maintenance Plan After the initial intensive weed treatment the site will continue to take inventory and treat weeds onsite. Each mid-April, a noxious weed survey will be made of the permit area. If any noxious weed patches or plants have been identified, they will be sprayed by backpack sprayer or 4 -wheeler using chemicals approved for use by the local Weed Management group in Garfield County. This will be done within 2 weeks of the inspection, when the weeds are most vulnerable. Care will be taken to spot spray wherever possible, to avoid killing desirable broadleaf plants. After reclamation of portions of the site and after final reclamation, weed surveys and spraying will continue until the perennial cover and crop production of the site have met. DRMS requirements and bond release has been obtained. The plan does not contemplate total weed removal on the property, especially the removal of some non -noxious weeds. Past experience shows that some initial weed cover in the first year following retopsoiling is beneficial to the reclamation effort in dry range sites. Weeds tend to provide shade for new grasses, are a means of holding snow on the seedbed longer and protect it from wind and water erosion until the planted species gradually take over the site. H. Revegetation Success Criteria Revegetation of all dryland reclamation will be deemed adequate when erosion is controlled and the vegetation is considered satisfactory by the DRMS. Garfield County officials can monitor the reclamation at any time and can provide comments to the DRMS regarding any bond releases. Additionally as the mining face progresses, the area that will become visible must have temporary vegetative cover. The reference point for this evaluation is point #7 and is shown on the General Blue Pit - February 2010 C-8 Location Map of the Visual Impact Report which is included in Appendix G. The lower bench of the reclaimed area (29.21 acres) will be restored to irrigated pasture. The success criteria of this area is 90% of the production of alfalfa/grass from the pre - mine fields. 1. Monitoring Reclamation Success Monitoring the reclamation on an ongoing basis will help to ensure successful reclamation. The operator plans to use the local NRCS office to assist in determining the ability of the reclaimed land to control erosion and make any other suggestions which may enhance the reclamation of this site. If minor changes or modifications are needed to the seeding or reclamation plan, revised plans will be submitted to Garfield County. It is hoped that Garfield County will provide assistance in evaluating the success of the ongoing reclamation process. Monitoring of the visual impact mitigation through temporary and permanent revegetation will also be monitored to ensure that the raining operation does not create any unnecessary visual impacts. 6. Geotechnical Stability Analysis There are no buildings or any structures outside the permit area which could be affected by the excavation. A minimum fifty foot buffer will be maintained from the permit boundary line to all excavations. All reclaimed areas will be restored to relatively flat (<3.5%) slopes except for the side slope, which be mined to a 1.5H:1 V and reclaimed to a 3H:1V slope. The surface material of these slopes will be topsoil. During placement of the backfill material, the operator will compact using standard earthmoving techniques. The soil type of the overburden and waste fines used in the backfilling of the side slopes will range from sand -silt -clay with slightly plastic fines to inorganic silts and clayed silts. Design factors In the extremely remote case that a slope failure would occur, if the slope failed up to the overhead power line west of the permit area (the closest man made structure to the operation), Figure 4-502.C(6)A shows the slope angle that would occur. The horizontal distance from the edge of the excavation to the power line is 55 feet. The failure angle would be 20 degrees or 2.7H:1 V. This angle is far milder than normal failure angles in material that gets strength from internal angle of friction. Figure 4- 502.C(6)B, from Huang, shows typical internal angles of friction for various materials. Assuming that the gravel is classified as GC, clayey gravels, poorly graded gravel — sand - clay, this material has an internal angle of friction of approximately 34 degrees. Blue Pit - February 2010 C-9 The Factor of Safety (FOS) for gravel with a 20 degree slope in GC classified material with an assumed internal angle of friction of 34 degrees can be approximated by ignoring the cohesion component of the stability and simply evaluating the internal angle of friction as follows: FOS = FOS = Tangent of Internal Angle of Friction Tangent of Actual Angle of Failure Surface Tan 34° .67 Tan 20° .36 2.0 This factor of safety far exceeds the normal long term safety factor of 1.3, therefore the plan of extraction, as presented in Figure 4-502.C(6)A, is acceptable. In addition, the exposed 1.5H:1 V gravel slopes will only be present for a short period of time, since the mine will be conducting contemporaneous reclamation. These backfilled slopes are at a slope of 3H:1 V. The backfilled material will consist of overburden from previously excavated areas or reject fines, which is similar to the overburden. I, Greg Lewicki, P.E., with over 28 year of experience in mine slope safety analysis in Colorado, certify that the mine plan and reclamation plan presented in this application will lead to stable slopes during and after mining and that there is no realistic threat of failure or to the stability of any structures outside of the permit area. iY6Ozai Greg Lewicki, P.E.

Site Map The erosion control measures to be installed are shown on Map F (Reclamation Plan Map) which is located in Appendix B. b. Drainage Structures There are no drainage features that enter the Blue Pit. Surface water runoff is routed around the site in the Basin and Spring Ditches. A small area north of the expansion area could potentially drain to the pit but a small berm will be installed, as shown on Map F (Reclamation Plan Map) to prevent this inflow. The berm will direct these undisturbed flows to the west. All surface water runoff from the disturbed area drains to the pit floor and will not leave the site. c. Topography The existing site topography is shown on Map C-1. The proposed mining topography is shown on Map C-2. The reclamation topography is shown on Map F (Reclamation Plan Map). d. Grading Plan The final grading of the site is shown on Map F (Reclamation Plan Map). The final slopes of the site will be 3H:1V for Mining Areas 2 though 5. Mining Area 1 of the existing operation will be reclaimed to 2.5H:1 V. Additionally a small berm will be installed on the north side of Mining Area 3 and 5 to assure that no runoff from the irrigated pasture enters the pit. e. Stockpiles The stockpile areas will be graded to protect the stockpiles from erosion. The topsoil stockpile will be revegetated with the temporary seed mix to reduce wind and water erosion. f. Drainage Plan The proposed drainage plan is shown on Map F (Reclamation Plan Map). g. Equipment Storage Equipment and fuel is stored south of Mining Area 2. h. Temporary Roads Existing roads are shown on Map C-1. Roads to be used during mining are shown on Map C-2. Final reclamation roads are shown on Map F (Reclamation Plan Map), i. Areas of Steep Slope The mining slope is 1,5H:1V (67%). The reclamation slope in Mining Area 1 is 2.5H:L1V (40%) and 3H:1 V (33%) in Mining Area 2-5. j. Construction Schedule The majority of the erosion and sedimentation control features will be installed on the reclaimed slopes. The reclaimed slopes will be created as areas become available over the next 35-40 years. Blue Pit - February 2010 D-1 • • • The temporary revegetation of the topsoil pile will be within 6 months of the topsoil being placed. k. Permanent Stabilization Permanent stabilization of the rangeland slope areas will be achieved through seeding with the rangeland seed mix. Also the stormwater catchment benches will be installed with a concrete lined ditch for the water to get to the pit floor. Permanent stabilization of the irrigation areas will be through seeding with the irrigated pasture seed mix and installation of irrigation system. 1. Erosion Control Measures Erosion control measures are shown on Map F (Reclamation Plan Map). m. Estimated Costs The estimated cost of temporary revegetation is approximately $2,000 per year. This includes seeding and supplemental irrigation. All other costs associated with erosion and sediment control items are for the permanent structures. n. Calculations The Stormwater Catchment Benches and Grouted Channel structures were designed to develop this Erosion and Sedimentation Control Plan. The Stormwater Catchment Benches The slopes of the reclaimed Blue Pit are very long and need to be protected from erosion. The maximum amount of unbroken slope that will be allowed in the reclamation is 30 vertical feet. The breaks in the slope are going to be the Storrnwater Catchment Benches which will collect the water and transport it to the 3 Grouted Channels, which bring the water to the bottom of the site. Figure 4-502A shows the ditch and channel designs. The Stormwater Catchment Bench design is shown below, Longest segment of Stormwater Catchment Bench 2,700 feet Curve Number 79 Drainage Basin Area 6.19 acres Precipitation Event 24 Hour 100 year Type II storm Rainfall 2.4 in Runoff 0.40 acre -ft Watercourse slope 2.0 % Time of Concentration 19.7 min Peak Discharge 4.07 cfs Side Slopes 3H: I V, 8H:1 V Manning Coefficient 0.02 Depth of Flow 0.65 feet Freeboard Depth 0.10 Feet Blue Pit - February 2010 D-2 • The Grouted Channels The Stormwater Catchment Benches collect the water from the slopes and transfer it to the Grouted Channel to be taken to the pit floor.

Surrounding Land The surrounding land consists of irrigated pasture, Highway 82, rangeland slopes and an exhausted landfill. The surrounding land is shown on Map C-1. p. Stormwater Management Concepts The general plan for controlling stormwater on site is to prevent undisturbed runoff from entering the pit and direct runoff from the pit slopes to the pit floor and allow it to infiltrate to the groundwater. q. Additional Calculations All calculations used to determine erosion and sedimentation control structures are included in section n of this exhibit. r. Maintenance of Best Management Practices The BMP's for this operation are the contemporaneous reclamation of the slopes, the installation of bench ditches and the installation of grouted channels to bring the water to the bottom of the pit. Western Slope Aggregate is responsible for the maintenance of theses structures. If there is any evidence that the structure will not continue to operate after reclamation, the Division of Reclamation, Mining and Safety will not release the reclamation bond. The schedule of the maintenance of these structures will be as needed and the cost associated with this maintenance is included in part m of this exhibit. s. Stormwater Management Plan Application A Discharge Permit is not required for this site through the Colorado Department of Public Health and Environment because there will be no discharge, since the entire operation drains to the pit bottom. The Stormwater Management Plan is a sub part of this permit and is therefore also not required. See the attached letter from Kathryn Dolan of CDPHE for more information.

The stormwater regulations apply to mines only if runoff contacts overburden, raw material, intermediate or finished product, or waste products, and has a reasonable potential of reaching state waters. If all runoff from the mine site an any of the disturbed areas is contained on site, with no discharge off-site expected, a stormwater permit is not required. The Clean Water Act does not establish a threshold (e.g., a 100.year storm event); the potential for any discharge is determined by the site owner/operator. If the owner/operator determines that no permit is needed and so does not apply for one, keep in mind that any change in Ibis situation would require application for a stormwater permit at least 30 days prior to any discharge taking place. If you have any questions, please give me a call at (303) 692-3596.

The Blue Pit is separated from the Roaring Fork River Valley by an 80' tall natural slope which remains after removing the gravel from an elevated alluvial terrace. The groundwater level limits the mining of the deposit at approximately 90 feet deep in the expansion area and 60 feet in current permit area. The groundwater surface is estimated from the existing excavation and by exploration drilling conducted in the area. Groundwater will not be intercepted my mining. The site has been mined since 1981 under the state Reclamation Permit # M-1981-207. Western Slope Aggregate has operated the site since 1991. The site expanded to an annual production rate of approximately 450,000 tons per year. The existing permit area is 82.70 acres; approximately 25 acres is still able to be mined. This application in 2010 is to allow for an expansion area of approximately 60 acres, all of which will be used for additional gravel mining. The proposed landscaping features are shown on the Landscaping Plan Map. Existing Erosion and Sedimentation Control Measures The landscaping plan is designed to reclaim the mining areas to rangeland and irrigated pasture. The existing area of the mining operation will be reclaimed to irrigated pasture, rangeland and industrial. A breakdown of the post mine land use is shown below. Post Mine Land Use Table Land Use Acreage Rangeland 104.07 irrigated Pasture 29.21 Roads 5.12 Industrial 8.47 Total _ 146.87 The landscaping is designed based on the post mine land use of a particular area. Reclamation tasks will be conducted as areas become available. The general schedule of reclamation activities will be delineated by the exhaustion of reserves in each mining area. The timing is dependent on demand and is expected to take place over the next 35 years. After Mining Area 1 Is Mined Out • Backfilling of the northern slope within Mining Area 1 After Mining Area 2 Is Mined Out • Backfilling of the southern slope within Mining Area 2 • Temporary revegetation of the southern slope of Mining Area 2 for erosion and sediment control as well as visual impact mitigation • Placing the Basin Ditch within an inverted siphon Blue Pit - February 2010 E-1 After Mining Area 3 Is Mined Out • Reclaim pit floor in Mining Area 2 to irrigated pasture • Revegetate the southern slope of Mining Area 2 with the rangeland seed mix • Reclaim temporary stockpile and wash plant area to rangeland • Reroute the farm access road (shown on Erosion Control Map 2) After Mining Area 4 Is Mined Out • Backfill and revegetate northern slope of Mining Area 3 to rangeland • Backfilling of the southern slope within Mining Area 4 • Temporary revegetation of the southern slope of Mining Area 4 for erosion and sediment control as well as visual impact mitigation After Mining Area 5 Is Mined Out • Backfill and revegetate all remaining slope of Mining Area 4 and 5 to rangeland • Reclaim all remaining portions of the pit floor in Mining Areas 2-5 to irrigated pasture. Irrigated Pasture The irrigated pasture will be landscaped by placing topsoil back on the pit floor and seeding the land with the irrigated pasture rnix. The existing side roll irrigation system from the pre mined irrigated pasture will be reused on the post mine irrigated pasture. Alt equipment will be removed from the irrigated pasture area. See the Landscape Plan Map for the location of the irrigated pasture. No trees or shrubs will be planted in this area. The irrigated seed remix will be drill seeded into the tilled soil with 2,000 lbs of straw per acre. The cost of topsoil placement and seeding is anticipated to be $3,000 per acre and 29.21 acres = $88,000. Western Slope Aggregate operates the current irrigated fields for the landowner and will likely continue this practice until the DRMS bond is released.

These areas are shown on the Landscape Plan Map. The rangeland seed mix will be drill seeded into the tilled soil with 2,000 lbs of straw / acre. The rangeland seed mix has Four Wing Saltbrush and Rubber Rabbit Brush include providing the shrub requirement in the rangeland landscape. These shrubs are anticipated to be of the 5 gallon size prior to the end of mining in a majority of the rangeland areas because the seeding will take place many years ahead of mining completion. Supplemental irrigation may be used during drought years. Tree saplings are excluded from the revegetated areas since they are not needed to mitigate visual impacts and the root system could interfere with the post mine drainage ditches. Additionally, prior to these field being used for irrigated pasture they were a grass/shrub mix with minimal trees. This irrigation is planned to be accomplished by water truck. Backfilling is a critical part of the rangeland landscaping on the slopes. The mining slope is 1.51-1:1V in all areas. The reclamation slope is 3H: I V in all areas except Mining Area 1 which was previously approved at 2H:1 V. This material will come from wash fines, overburden and imported fill.

This protection consist of Stormwater Catchment Benches and Grouted Channels. The catchment benches will be installed on the slopes when the topsoil is being placed. These benches will run to the grouted channels to remove the stormwater from the slopes. The design for the catchment benches and grouted channels are shown below.

Blue Pit - February, 2010 E-5 Industrial The concrete plant is not operated by Western Slope Aggregate and it has its own special use permit through Garfield County, therefore, it is anticipated that upon mining and reclamation being completed the concrete plant will remain in place. No landscaping is planned in the industrial area since it is currently being used for that purpose. The access road leading to the concrete plant will also remain in place until the concrete plant is removed. There are no cost associated with the landscaping of the concrete plant area. Farm Access Road The farm access road that is currently in use will be removed during mining and will be replaced with a bypass road that is located on the west side op the operation. This road will allow the landowner to continue to use the existing access road without having to travel into the pit to access the property. The construction of this road is expected to cost $30,000 since the materials and equipment are already on site. The farm road will be maintained by Western Slope Aggregate until the DRMS bond is released. Landscaping Installation and Maintenance Cost Estimate Current DRMS Reclamation Bond The current Reclamation bond is $307,000. An updated bond calculation will be needed when the Blue Pit amendment application is submitted to DRMS. It is likely that the reclamation bond will increase due to a larger permit area and more elaborate reclamation plan. Slope Bacll The anticipated cost of handling the backfill material is $0.85 / C.Y. The entire site needs to handle approximately 3.5 million C.Y. over the next 35 years. This would cost nearly 3 million dollars, but since it done on an ongoing basis and is never needed all at once the DRMS reclamation bond is far less than this total. Benches and Channels Installation of all the catchment benches are anticipated to cost $80,000. This cost covers the regarding of the backfill material to create benches at a 2% slope. The three grouted channels have a linear distance of approximately 1,000 feet. The anticipated installation cost of the channels is $20,000 since the aggregate and concrete supply is onsite. The benches and channels will need maintenance in the early years until the vegetation becomes established. This maintenance will be performed by Western Slope Aggregate on an as needed basis. The maintenance will be hand grading to fix any bypasses or breaches. This maintenance is not expected to be needed after the first 5 years of reclamation. Since the site will be reclaimed through out the mine life the expected cost is $2,000 per year for the life of the mine plus 5 years. Topsoil Replacement The topsoil replacement and seeding will also be conducted as areas become available but the total cost is estimated at $3,000 per acre and there are 104.07 acres that will be reclaimed to rangeland. That is an anticipated cost of $312,000. This topsoil will be placed after the final Blue Pit - February 2010 E-6 grading of the benches. The topsoil will be replaced on an ongoing schedule and will not cost this full amount at any one time. Seeding/Irrigation Areas that are topsoiled will be seeded with the Rangeland or Irrigated Pasture seed mix depending on the post mine land use of that area. Placing the seed will occur as areas are ready and not all at one time during the operation. The anticipated cost of placing the seed and initial supplemental irrigation is $1,200 per acre and there are 104.07 acres that will be reseeded which is a cost of $124,884. The cost of final irrigation of the irrigated pasture is not included because at that point it is associated with the farming operation and the reclamation liability will be released for that portion of the site. Totals The total cost of the landscaping of the fully mined out Blue Pit would be $3,632,000. This would never be the reclamation cost at any time. Contemporaneous reclamation minimizes this cost of the worst case reclamation scenario to the total of the DRMS bond which is $307,000. Blue Pit - February 2010 E-7 4-502.D Land Suitability Analysis Exhibit F 1. Public Access There is no public access to the site currently, historically or planned for the future. The only users of the site are associated with the mining operation and the landowner. 2. Access to Adjoining Roadways The site accesses Highway 82 through the use of a private access road which is shown on Map C-1. This access point has an access permit with CDOT which is included in Appendix C. The Highway 82 access point has very good site distances and has existing accelldecel lanes. Additionally the site has a northern access route that is rarely used. This northern route uses CR103 and CR104 to access Crystal Spring Road. 3. Easements There is a gas line and overhead power line easement located on the adjacent property. These structures are shown and delineated on Map C-1. The easements are not associated with the subject property. 4. Topography and slope The topography and slope of the existing site is shown on Map C-1. The topography and slope of the proposed mining and reclamation plans are shown on Map C-2 and Map F (Reclamation Plan Map) respectively. The reclamation slopes are similar to the native slopes of the area. 5. Natural Features There are no significant natural features on or off site. 6. Drainage Features The Basin and Spring Ditch divert the existing surface runoff from up gradient of the mining operation around the site. There are no drainages or impoundments that are located within the expansion area. 7. Water As seen on Map C-1 the expansion area is irrigated pasture. This has been the use of this land since before the mining operation started. The water supplied to the irrigated pasture comes from the Basin and Spring Ditch. The mining operation also has an approved augmentation plan for this water consumption. Additionally there is a well on site to provide water for the mining operation in the months during which the ditches are not running. 8. Floodplain The Blue Pit is not located within or near any floodplains. 9. Soils The average topsoil thickness available for salvage is expected to be 12". This topsoil will be stockpiled or directly replaced on reclaimed areas. The soil of the irrigated pasture Blue Pit - February 2010 F-1 • • area is very porous and requires large amounts of irrigation water to facilitate high production. The soil unit boundaries are shown on Map C-1. The descriptions of these soil units are included in Exhibit G. 10. Hazards With a mining slope of 1.5H:1 V and backfilling to 3H:1 V, there are no geological hazards within the mining area. Additional information can be found in the geotechnical study located in Exhibit C. There are no hazards adjacent to the expansion area, 11. Natural Habitat No trees are to be removed during the expansion of the Blue Pit. The vegetation of the expansion area is primarily irrigated pasture which consists of alfalfa and other pasture grasses. Wildlife does use the expansion area during various times in the year but this operation is not expected to significantly impact wildlife, since the existing operation has not shown to do so. Additional information concerning wildlife is included in appendix H. 12. Resource Areas This site does not have any known archeological, paleontological or historical importance. If a site of such importance is found during mining, the Colorado Historical Society will be consulted on the correct procedure for handling the site. The Colorado Historical Society file search results are shown in Appendix I. Blue Pit - February 2010 F-2 4-502.E Impact Analysis Exhibit G 1. Adjacent Property The adjacent landowners to the two parcels of land which the Blue Pit is located on are outlined in Table 4-502.E(1) Adjacent Landowners. The parcel locations are shown on Figure 4-502.E(1) Adjacent Landowner Map. As shown on the Adjacent Landowner Map the majority of the property directly adjacent to the proposed expansion area is owned by the Blue Family. Impacts to the adjacent property owners as well as others in the general area of the expansion area are addressed in the remainder of this exhibit.

Site Features The Spring Ditch and the Basin Ditch are within the Blue Pit Expansion Area, The Basin Ditch has an average flow of approximately 40 C.F.S. while the Spring Ditch is approximately 1 C.F.S. These ditches will be kept operational throughout the mine life. Surface water from up gradient of the expansion area is primarily collected by these ditches and will not significantly be encountered within the mining operation. The ground water has been shown to range from 60'-90' below the natural surface at the site and mining will not intercept groundwater. Table 4-502.E(3) shows the climate data for Glenwood Springs which receives similar amounts of precipitation and is at a similar elevation to the site.

Geology and Hazard The geology of the site is an alluvial gravel deposit which is 50-90 feet taller than the river valley floor. The gravel deposit is much deeper than 90 feet below the natural ground level but ground water is encountered prior to reaching the full depth of the deposit. The hill side up gradient ofthe site consists of fine grained gypsum material. This hill side has an average slope of approximately 5H:1V(20%) and is not at risk ofa slope failure due to the mining operation. 6. Water Supply Water is supplied to this operation from the Basin Ditch. This consumption is covered through an approved augmentation plan. Additionally water is supplied from the well on site which is shown on Map C-1. Potable water is purchased from a supplier and is delivered to the site by truck. 7. Groundwater and aquifer recharge Groundwater and aquifer recharge is not expected to be altered by this operation. The mining operation will not intercept groundwater. Also, irrigation of the permit area will continue ahead of the mine sequence as well as after reclamation to continue to recharge the aquifer. 8. Environmental effects a. Flora and Fauna No trees are to be removed during the expansion ofthe Blue Pit. The vegetation ofthe expansion area is primarily irrigated pasture which consists of alfalfa and other pasture grasses. Wildlife does use the expansion area during various times in the year but this operation is not expected to significantly impact wildlife, since the existing operation has not shown to do so. Additional information for impacts to wildlife is included in appendix H. b. Archaeological This site does not have any known archeological, paleontological or historical importance. If a site of such importance is found during reining, the Colorado Historical Society will be consulted on the correct procedure for handling the site. No impact to any archeological, paleontological or historical importance site is expected. The Colorado Historical Society file search results are included in Appendix 1. c. Radiation This site is not expected to have any impact of the radiation levels in the area. d. SPCC A Spill Prevention Control Countermeasure Plan has been produced for this site since it stores greater than 1320 gallons of petroleum products on site. The SPCC plan is included in Appendix A. Blue Pit - February 2010 G-12 • 9. Traffic The haul traffic from the current operation exits the site from a private road and intersects Highway 82 as shown on Map C-1. The haul traffic for the expanded operation will access the site in the same fashion as it does currently. The existing access to Highway 82 has an access permit from CDOT and the permit is included in Appendix C. Even though the Blue Pit is expanding, the annual production is going to stay the same which means the truck traffic will stay the same. A traffic study will be conducted if required by CDOT to keep the existing access permit, but it is our understanding that a traffic study is not needed. There is a small amount of truck traffic that accesses the area north of the Blue Pit through CR 103 and CR 104. This access route is only used for product sales north of the pit on Crystal Spring Road and is a very small amount of the annual production. 10. Nuisance Western. Slope Aggregate knows that there are impacts the surrounding community from this gravel mining operation. The mining and reclamation plan has been designed to mitigate these impacts to the fullest extent possible. Glare, vapor, smoke and vibration are not expected to be a nuisance at this operation due to the type of mining operation and the products made on site. Dust - The processing equipment, along with the mining operation, has air emission permits in place and will not be changed as part of this expansion. These air permits need to be revised every 5 years and will be kept up do date with items relative to dust emissions. Noise — Western Slope Aggregate has operated the site since 1991 and has not had a noise violation. WSA will continue to operate the site below the state noise limits. A full noise study was conducted and the report is included in Appendix E Visual Impact — Visual impacts have been mitigated through the use of the natural topography, project phasing and mining the deposit from the bottom where possible. The visual impacts were studied using 3D models of the mining and reclamation plan and site photos. The Visual Impact Report shows the different views of the site and addresses visual impact. This report is included in Appendix G. 11. Reclamation Plan The Reclamation Plan has been produced to satisfy the requirements of Garfield County with one variation. The proposed reclamation plan calls for the final slopes to be at 3H:1V or shallower, while the regulation 7-840.H(1.b) requires 5H:1V slopes on all dryland areas. A variance is believed to be suitable in this case as the slopes are hidden from view from the general public, excluding the homes north of the site. 3H:1 V slopes will maximize the resource recovery, as well as the land available the irrigate after mining. The full reclamation plan is included in Exhibit C. Blue Pit - February 2010 0-13 Improvement Agreement Exhibit H Blue Pit - February 2010 H-1 Section 7 Division 1 General Approval Standards for Land Use Change Permits Exhibit I 1. Compliance with Zone District Use Restrictions The Blue Pit Expansion Complies with zoning regulations. 2. Compliance with Comprehensive Plan and Intergovernmental Agreements The Blue Pit Expansion is consistent with the Garfield County Comprehensive Plan. 3. Compatibility The expansion of the Blue Pit is not changing the intensity or scale of the project. This expansion only extends the number of years that it will be operating. Impacts to surrounding property are addressed in Exhibit D. 4. Sufficient Legal and Physical Source of Water A. Determination of Reliability of Water Supply 1) Peak Usage The peak usage is not going to change at this site since production is not changing. The approved Augmentation plan allows for 7.4 acre-feet of water to be pulled from the Basin Ditch each year. 2) Adequacy of Water Source The anticipated water use is 7.4 acre-feet per year. 3) Quality of Water Source Potable water for the site is bottled water. 4) Irrigation Water The irrigation water comes from the Basin and Spring Ditches. The water right is included In Appendix J. 5) Fire Protection Requirements Currently there is no water supply for fire protection. Upon request by the local fire protection district, a cistern tank may be installed. Blue Pic - February 2010 I-1 • • B. Individual Wells There is only one well on site and it is used for industrial use, primarily to supply the concrete plant. No new wells are planned. 5. Adequate Water Supply A. Authority B. Water Supply Requirements 1) Water supply requirements are not changing as part of this application. The estimated supply requirements are 7.4 acre-feet per year. The breakdown is as follows: Pond Evaporation 1.35 Acre-feet Dust Control 1.54 Acre-feet Crusher / Screen 2.09 Acre-feet Concrete Truck Washout 2.38 Acre-feet 2) The source of the water to be used by the Blue Pit Expansion is the Basin and Spring Ditch. Also there are 2 wells on site which supplies water to the concrete plant and the shop. These items are shown on Map C-1. 3) The water supplied from the Basin and Spring Ditch as well as the well on site are not used for drinking water. Potable water is provided by bottled water. 4) The Basin and Spring Ditch only run during irrigation season. The well on site is not affected by seasonal variations. During non irrigation season, all water for the operation comes from the well. A majority of the water demands are during irrigation season. 5) Water used in the material washing operations will be recycled through the plant to reduce the annual amount of water used. Water recycling is currently conducted at the Blue Pit. 6) A majority of the water consumption occurs during irrigation season. Washed material is stockpiled through the winter to reduce winter water needs. 7) The approved augmentation plan is included in Appendix J. C. Water Supplied by Water Supply Entity Requirements Blue Pit - February 2010 1-2 • 1) Water is supplied from an onsite source therefore this section does not apply to the Blue Pit Expansion. D. Determination of Adequate Water Supply 1) The approved augmentation plan as well as the consumption estimate should allow the Board of County Commissioners to determine adequate water supply. b. Adequate Central Water Distribution and Wastewater Systems A. The locations of the water use change as mining progresses which makes a central distribution system impractical. B. Wastewater System Standards I. Wastewater requirements for the Blue Pit are handled by portable toilets. 7. Adequate Public Utilities This site has adequate public utility service. 8. Access and Roadways A. (this item was blank in the County Regulations) B. This parcel has access to Highway 82. C. The access road connecting the site to Highway 82 is safe and is not going to be changed in the expansion of the Blue Pit. D. No additional traffic will be produced by the expansion of the Blue Pit. The existing access safely and efficiently handles the traffic from the site. 9. No Significant Risk of Natural Hazard The Blue Pit Expansion is not subject to significant risk from natural hazards and will not exacerbate existing natural hazards. Blue Pit - February 2010 I-3 Section 7 Division 2 General Resource Protection Standards For Land Use Change Permits Exhibit J 1. Protection of Agricultural Lands A. No Adverse Affect to Agricultural Operation. The operation of the Blue Pit Expansion area will allow the majority of the parcel to remain as agricultural use. The mining operation is expected to take 35-40 years and the portions to be mined later will have irrigated pasture as long as possible. Additionally the land will go back to agricultural use after reclamation, B. Domestic Animal Control Domestic animals will not be allowed to interfere with livestock. C. Fences All fences between the property of the Blue Pit and adjoining property will be maintained. D) Roads All new roads are set back a sufficient distance from property boundaries to allow for maintenance without damaging fences. Dust will be controlled on these roads. E) Irrigation Ditches 1, Maintenance The use and maintenance ability of the Basin and Spring ditch will remain through mining and after reclamation. 2. Right-of-ways The Blue Pit Expansion will not interfere with the Basin or Spring Ditch rights-of-way. 3. Maintenance Easements A maintenance easement of twenty-five (25) feet from the edges of the Basin and Spring Ditch banks shall be preserved and indicated on Map F (Reclamation Plan Map). 2. Protection of Wildlife Habitat Areas A. Buffers A Wildlife and Habitat Assessment has been prepared and is included in Appendix H. The mining operation will be primarily on the pit floor which provides a screen to the wildlife habitat areas. Blue Pit - February 2010 J-1 • B. Locational Controls of Land Disturbance The Blue Pit Expansion will have very little further impact on the wildlife of the area than does the current operation. Migratory routes will not be blocked by the disturbance. C. Preservation of Native Vegetation The vegetation that will be disturbed by the expansion area is primarily irrigated pasture grass/alfalfa. This is not the native vegetation. Trees and shrubs of the rangeland areas will not be removed. The rangeland seed mix described in the reclamation plan is designed to mimic the native rangeland vegetation. A weed management plan is included in the Reclamation Plan to prevent weed infestations after soil disturbance. D. Habitat Compensation Critical wildlife habitat is not being disturbed. F.

All Lighting will be directed inward and downwards towards the property. 7. The Blue Pit is one continuous pit, but reclamation activities will follow the mining operation to the extent possible. Further details of the reclamation sequencing can be found in the Visual Impact Report or in the Reclamation Plan included in Exhibit C. E. Impacts to County Road System 1, The existing operation access directly to the state Highway 82. There is an approved access permit through CDOT and it is not expected to need revision. The traffic from the site will stay the same as it is today under the existing permit. 2. There is an alternate access route to the north of the site but does not see a significant number of trucks since it is only used when hauling to the homes north of the Blue Pit. Blue Pit - February 2010 K-2 • • • 3. The access to the site is directly to the State Highway and therefore Western Slope Aggregate does not need to submit evidence of insurance. 4. There are no road upgrades needed since the traffic volume is not increasing. 5. All access used for the expansion area are existing with existing access permits. 6. Western Slope Aggregate will repair road damage that is caused by the operation of the Blue Pit. F. Impacts to Wildlife 1. The Wildlife and Habitat Assessment is included in appendix H and states that there are no threatened or endangered species or habitats within the Blue Pit Permit Boundary. G. Compatibility with Surrounding Land Use 1. The mining operation is offset 50 feet from the property boundary. There are no off property damages expected from the operation of the Blue Pit Expansion Area. 2. Equipment storage is not located within 300 feet of a residence. 3. Loading and unloading will be conducted primarily on the pit floor which is on private property. 4. Storage areas not associated with natural resources will be less than 10 acres. 5. All lighting of storage areas will be directed downwards and inwards and will not directly reflect to the adjacent land. 6. The Blue Pit expansion is compatible with surrounding land uses. The existing. site has been a gravel pit for many years. There is an old waste dump to the east of the pit, Highway 82 well below the terrace to the south, the Blue Pit landowner (Dee Blue) owns the land to north and uses it for a tree farm and irrigated pasture. There is an area of pinyon juniper also owned by Dee Blue to the north of the eastern portion of the property. The immediate area to the west is irrigated field, however, La Farge has another gravel mining operation in the same terrace deposit approximately 2000 feet west of the west permit boundary. 7. The closest mining operation to the Blue Pit expansion is approximately 2000 feet to the west and is nearing final reclamation. Blue Pit - February 2010 K-3 • • 8. The hours of operation of the Blue Pit will continue to be from 7:OOAM to 8:00 Monday through Saturday with crushing, mining and heavy hauling only being allowed from 7:00 AM to 7:00 PM to allow from administrative and maintenance activities to occur until 8:00 PM. H. Reclamation / Enforcement 1. The slopes of the reclaimed land are addressed in the Reclamation Plan which is located in Exhibit C. A variance from the standard is requested for this site from 5H:1 V to 3H:1 V. The existing approved reclamation plan states 2.5H:1V reclaimed slopes. Mining Area 1 will be reclaimed to 2.5H:1 V and Mining Areas 2-5 will be reclaimed at 3H:1 V. This is milder than that currently allowed but steeper than the slope standards outlined in Section 7-840.H(1) for dryland slopes. Reasons to allow the reclaimed slopes at 3:1 are given below: 1) One of the principal reasons behind the requirement for 5:1 slopes was the focus on wet pits along the 1-70 corridor. This pit is not a wet pit, since the gravel occurs in an upland terrace and it is far removed from 1-70. 2) Visual concerns are an important part of the desire for 5:1 slopes, since the visual aspect of the reclamation from well traveled highways is a long term concern. This concern is well mitigated at the Blue Pit since Highway 82 is the only well traveled highway within any reasonable distance from the pit and it is located well below the active pit. No pit operation will ever be seen from Highway 82. The highway is well vegetated and will remain that way. The access road was installed years ago and its slopes are well vegetated This road will be used for the life of the extended operation. 3) The pit is visible from some of the homes in the rural housing located north and uphill of the pit. An extensive plan has been developed that utilizes the depth of the pit, combined with sequencing and temporary reclamation, to mitigate the visual aspects of the operation from these homes. See the Visual Impact Report located in Appendix G. 4) The pre -mining use of the land is an irrigated field. The landowners desire that as much land as possible be restored to irrigated field, which will be at the bottom of the slopes. Restoring the slopes to 5:1 would greatly reduce the amount of irrigated area at the bottom, since the expected depth is approximately 90 feet. 5) The reclamation plan calls for 2 benches of 6 feet width in a slope height of 90 feet, therefore, the overall slope will be reduced from 3:1 to 3.1:1. These slopes will also be used to collect Blue Pit - February 2010 K-4 runoff from the slope itself and reduce erosion. The 3.1 slope will be bac/Oiled, topsoiled and reclaimed to dry rangeland, as desired by the landowner and required by the DBMS. 2. The seed mixes to be used during reclamation are outlined in the reclamation plan. The site will be continuously reclaimed as mining progresses over the next 35-40 year. This is plenty of time for the shrubs to be planted to reach the 5 gallon size. Supplemental irrigation will be used on the temporary seeded areas and only during drought conditions in the rangeland areas. The irrigated pasture areas will be irrigated. 3. Ponds will not be created in the reclamation of the Slue Pit. 4. All disturbances at the Blue Pit will be covered under the DRMS bond. Garfield County can choose to be involved in the bond recalculation process. 5. Since the DRMS reclamation permit amendment has not yet been submitted, all conditions agreed upon during the Major Impact Review will be included in the DRMS amended reclamation permit. 6. Annual reports of the reclamation progress will be submitted to Garfield County. 7. Western Slope Aggregate welcomes Garfield County Inspectors to inspect the site with site personnel upon notice. 8. 'Western Slope Aggregate welcomes Garfield County Inspectors to inspect the site with site personnel upon notice. 9. Other permits that are required for this site are regulated through the following agencies: CDPHE Air Quality Control Division 303-692-3150 Division of Reclamation Mining and Safety 303-866-3567 CDOT Grand Junction office 970-248-7000 The following agencies do not regulate this site since there is not going to be a discharge to state waters from this site nor are there any wetlands on this site: CDPHE Water Quality Control Division 303-692-3500 US Army Corps of Engineers 970-243-1199 10. The Garfield County Inspector will be invited to any bond release inspections and have the opportunity to demonstrate that any item of the permit has not been complied with and that the bond should not be released.

Registration Number Blue Pit Page ri • • • 1.0 Introduction 1.1 Purpose The purpose of this Spill Prevention Control and Countermeasure (SPCC) plan is to prevent spills from occurring, and to perform safe, efficient and timely response in the event of a spill or leak (both referred to as "spills" herein). In accordance with United States Environmental Protection Agency (EPA) oil pollution prevention regulations (40 CFR 112), the operator must prepare and implement an SPCC plan for facilities that could reasonably be expected to discharge oil into or upon navigable waters or adjoining shorelines; and, meet one of the following conditions: • Above -ground oil storage capacity exceeds 1,320 gallons; or • Underground oil storage capacity exceeds 42,000 gallons, unless the underground tanks are subject to all of the technical requirements of 40 CFR 280 or a state program approved under 40 CFR 281. (Maine's approved program is Department of Environmental Protection, Chapter 691 — Rules for Underground Storage Facilities.) As defined by 40 CFR Part 112, oil includes all grades of motor oil, hydraulic oil, lube oil, fuel oil, gasoline and diesel, automatic transmission fluid (ATF), waste oil, and transformer mineral oil. The definition of oil also includes non -petroleum oils such as animal or vegetable oils and synthetic oils. 1.1.1 Using the Plan In addition to satisfying a regulatory requirement, this SPCC plan should be a working document at the facility. The plan should be used frequently in the following ways: • As a reference for oil storage and containment system information. • As a tool for informing new employees and refreshing existing employees on practices for preventing and responding to spills. • As a guide to periodic training programs for employees. • As a guide to facility inspections. • As a resource during an emergency response. L 1.2 SPCC Plan Revisions The operator must revise this SPCC plan for any change in the facility design, construction, operation or maintenance that affects the facility's potential for discharging oil. Revisions must occur as soon as possible, but no later than six months after the change occurs. The Facility Manager is responsible for initiating and coordinating such revisions. Additionally, this SPCC plan must be reviewed at least once every three years. Revisions to the plan, if any, must be made within six months of the review. Facility inforrnation related to the SPCC plan must be submitted to the United States Environmental Protection Agency (EPA) Regional Administrator whenever the facility discharges more than 1,000 gallons in a single event, or discharges more than 42 gallons of oil in each of two spill events within a 12 -month period. Blue Pit Page 1-1 1.2 Facility Description [112.7(a)(3)1 1.2.1 Location and Use The Blue Pit is located approximately 2.5 miles east of Carbondale, CO on Highway 82. The Blue Pit is separated from the Roaring Fork River Valley by an 80' tall natural slope which remains after removing the gravel from an elevated alluvial terrace. The site has been mined since 1981 under the state Reclamation Permit # M-1981-207. Western Slope Aggregate has operated the site since 1991. The site has been mined since the early 1980's and has expanded to an annual production rate of approximately 450,000 tons per year. This site is a dry alluvial terrace and mining will be conducted above the groundwater level. There will be no dewatering or water discharge from this site. All maps referred to in this plan can be found in the Colorado Division of Reclamation, Mining and Safety permit application. Once the pit has been dewatered, mining will begin. Primarily, front-end loaders will be used to mine the raw gravel. The slopes of the pit will be mined to 1.5H:1V slopes. Some dozer pushing or ripping may also he used. The loader will directly load to a primary crusher or into trucks which will deliver the material to the crusher. The crushing equipment is powered by an overhead power line and does need diesel power for operation. 1.2.2 Waterways and Abutters There are two irrigation ditches on site and are used to supply irrigation water to the Blue property as well as property to the west of the site. There is no petroleum product storage near these ditches. Once all mining has been completed the land will be reclaimed to irrigated pasture and rangeland. After reclamation all on site stormwater will infiltrate into the underlying groundwater. 1.2.3 Site Drainage Drainage will be directed into the pit bottom where it will infiltrate into the porous alluvial material. Blue Pit Page 1-2 2.0 Potential Spill Sources and SPCC Features 2.1 SPCC Compliance [112.7(a)(1) and 112.7(a)(2) and 112.8 The only permanent spill source onsite will be the fuel storage area. All other fuel tanks are associated with the mobile equipment or the concrete plant which is owned and operated by a different company, Casey Concrete. 2.2 Tables [112.7(a)(3)(i and iii) and 112.7(b)1 Fuel/Oil Dispensers Location Product / Size Spill direction Fuel Containment Area South of Shop Dyed Diesel -10,000 gallon Concrete Secondary Containment Fuel Containment Area South of Shop Highway Diesel -10,000 gallon Concrete Secondary Containment Fuel Containment Area South of Shop Gasoline -3,000 gallon Concrete Secondary Containment Mobile Equipment Name Quantity Fuel Tank (gal) Hydraulic System (gal) Wheel Loader 3 75 40 D8 Dozer 1 165 19 Note: This list is an estimate of on-site equipment.

Blue Pit Page 2-1 • • • 3.0 Spill Prevention and Response 3.1 Discharge Prevention 31.1 SPCC Features and Operating Procedures f112. 7(a)(3) and 112.81 The operator's employees are trained to implement spill prevention practices for work with and around oil sources. Personnel shall use common sense and rely on spill prevention practices at all times to minimize the potential for a release of oil. For example, the following "common sense" practices are recommended: • keep container lids securely fastened at all times; • do not leave portable sources unattended; • return portable sources to their storage location after use; • use pads, drip pans, and funnels when transferring petroleum products from a portable container; • protect oil sources from damage by moving equipment; • do not store oil sources near catch basins or floor drains; and • loading and unloading of petroleum products shall be attended at all times. Suppliers All suppliers will meet the minimum requirements and regulations for tank truck unloading as established by the United States Department of Transportation. These supplier procedures also ensure that the vendor understands the site layout, knows the protocols for entering the site and unloading product, and has the necessary spill equipment on board to respond to a spill from the vehicle or fuel delivery hose. Observations of Deliveries The Facility Manager or designee will supervise deliveries for all new suppliers and will periodically observe deliveries for existing, approved suppliers. Delivery observations include: • vehicle inspection prior to delivery and departure (e.g., to make sure the driver does not drive away with the hose in the fill pipe): • inquiry to ensure the truck contains the right product for the tank; • assurance that the tank can hold what the supplier intends to deliver; and • adequate spill response equipment is on board the vehicle Vehicle Filling Loading operations and vehicle fueling operations will be performed by facility personnel trained in the specific operation. The operators will: • check that the vehicle is properly secured before making connections, • inspect the storage and delivery system, hoses, connections and the receiving vessel before beginning operations, • monitor the transfer operation in-person from beginning to end, • check that the vehicle has been disconnected before departure, Blue Pit Page 4-1 • • • secure the storage and delivery system after use, and • Facility personnel will monitor the fueling area for safe and proper operation, and will take immediate action to correct any deficiencies. 3.1.2 Tests and Inspections [112.7(e) and 112.8 (c) (6)1 The personnel at the facility shall perform testing, inspection, and maintenance of all petroleum equipment to keep it performing in an efficient and environmentally sound manner. The tests and inspections shall be performed as discussed in the following subsections. 3.1.2.1 Inspecting AST's Facility personnel periodically observe the ASTs during operating hours. The ASTs shall be inspected monthly, and the results shall be recorded on the Monthly AST Inspection Report, as included in Appendix E. Spill response kits kept on site shall also be checked during the monthly AST inspection, and restocked as necessary. The monthly inspection reports shall be kept for at least three years in a file maintained by the Facility Manager. Inspections include observations of the exterior of the tank for signs of deterioration or spills (leaks), observations of the tank foundation and supports for signs of instability, and observations of the vent, fill and discharge pipes for signs of poor connection, that could cause a spill. Check for accumulation of precipitation. In addition to these monthly inspections, the facility will periodically verify the integrity of each tank every ten years, or more often as deemed necessary by the inspection results. Integrity testing will be conducted in accordance with an industry standard procedure such as STI — SPO01-03 or API 653. 33.2.1 Tank Maintenance All petroleum tank and piping problems shall be immediately reported to the Facility Manager. Visible oil spills (leaks) that cause a loss of oil from tank waits, piping or other components shall be repaired or replaced as soon as possible to prevent the potential for a major spill from the source. This is especially important for sources located outside or near drains or catch basins that discharge to the environment. 3.1.3 Training [112.709] The operator shall provide SPCC spill training for personnel involved with handling petroleum products. The Facility Manager shall arrange for annual training, which shall include the following training topics: • an introduction to pollution control laws; • rules and regulations pertaining to the use and storage of petroleum products; • inspection, operation and maintenance of spill equipment, and petroleum storage and dispensing equipment; • spill response and cleanup; • spill notification and record keeping; and • spill prevention practices.

This information shall be filed and maintained for at least 3 years at the office of the Environmental Compliance Officer. A Certificate of Training shall be presented to each employee that has completed the training. 3.1.4 Security [112.7(W No security issues are expected on this site. 3.2 Emergency Response [112.7(a)(3)(iv) and 112.7(c)] This section describes the cleanup response and protocols to follow in the event of an oil spill. The uncontrolled discharge of oil to groundwater, surface water or soil is prohibited by State or Federal laws. It is imperative that action be taken to respond to a spill once it has occurred. In the event of an oil spill, depending on the volume and characteristics of the material released, the operator has defined spill response as either a "Minor Spill Response" or "Major Spill Response" ("Spill Emergency"). A list of Emergency Contacts is included in Appendix A. 3.2.1 Minor Spill Response [112. 7000)(iv)] A "Minor Spill Response" is defined as one that poses no significant harm to human health or the environment. These spills involve generally less than 5 gallons and can usually be cleaned up by the operator's personnel. Other characteristics of a minor spill include the following: • the spilled material is easily stopped or controlled at the time of the spill; • the spill is localized; • the spilled material is not likely to reach surface water or groundwater; • there is little danger to human health; and • there is little danger of fire or explosion In the event of a minor spill the following guidelines shall apply: 1. Immediately notify the senior on-site person (i.e., Facility Manager). 2. Call the Colorado Department of Public Health and Environment, Colorado Division of Reclamation Mining and Safety, City of Carbondale, and the Garfield County Environmental Health Department within two hours. Document the telephone calls on the Spill Notification Form in Appendix B. 3. Under the direction of a senior on-site person, contain the spill with spill response materials and equipment. 4. Place spill debris in properly labeled waste containers. 5. Complete the Spill Notification Form (Appendix B) and send to the Environmental Compliance Officer. Blue Pit Page 3-3 • • • 3.2.2 Major Spill Response (Spill Emergency) (112. 7(a)(3)(iv)J A "Spill Emergency" is defused as one involving a spill that cannot be safely controlled or cleaned up. Characteristics include the following: • the spill is large enough to spread beyond the immediate spill area; • the spilled material enters surface water or groundwater (regardless of spill size); • the spill requires special training and equipment to cleanup; ▪ the spilled material is dangerous to human health; and • there is a danger of fire or explosion In the event ofa spill emergency the following guidelines shall apply: 1. All workers shall immediately evacuate the spill site and move to a safe distance away from the spill. 2. A senior on-site person shall call for medical assistance if workers are injured (no worker shall engage in rescue operations unless they have been properly trained and equipped). 3. A senior on-site person shall immediately calf the Colorado Department of Public Health and Environment, Colorado Division of Reclamation Mining and Safety, City of Carbondale, and the Garfield County Environmental Health Department within two hours. Document the telephone calls on the Spill Notification Form in Appendix B. 4. Notify the local Fire Department or Police Department. 5. A senior on-site person shall contact the Facility Manager and provide details regarding the spill. 6. The Facility Manager will coordinate cleanup and seek assistance from a cleanup contractor as necessary. 'fa senior on-site person is not available at the time of the spill, then the next highest employee in command shall assume responsibility. 3.2.3 Waste Disposal [112. 7(a)(3)(v)J Wastes resulting from a minor spill response will be containerized in impervious bags, drums or buckets. The waste will be removed from the site by a licensed waste hauler within two weeks. Wastes resulting from a major spill response will be removed and disposed of by a cleanup contractor. 3, 2.4 Waste Disposal [112. 7(a)(4)1 In the event ofa minor spill, a senior on-site person shall notify the Facility Manager and complete a written Spill Notification Form. This form details the time, material, and quantity of oil released.

April 6, 2010• Sate 450 s9O South Broadway Dew Colorado Tom Veijic ECM Garfield County 108 Eigth Street Glenwood Springs, CO 81601 Re: Blue Gravel Pit — Traffic Evaluation SH -82 and Blue Road/CR-103 Dear Mr, Veljic: It is understood that Western Slope Aggregate Inc. has requested a change in location of current excavations for the Blue gravel pit, located along the north side of SH -82 at the Blue Road/CR-103 intersection in Garfield County, Colorado. Although the proposal is to change location, the overall pit excavation area and access will remain the same. Western Slope Aggregate has identified that with the change in excavation location, the existing operations will be maintained. Please see attached letters from Western Slope Aggregate and Lewicki and Associates describing existing operations and proposed excavation areas. Therefore, based on this information and that the excavation area will remain under the CDOT Access Permit identified 1 1 0 acres for this same use, we believe that Blue gravel pit will be in compliance with the existing access permit. Based on the operations remaining the same for the existing Blue gravel pit, the amount of existing traffic generated by the gravel pit is not anticipated to change in the future due to the excavation location change. No increase in traffic volumes are anticipated along CR -104, CR -103, or SH -82 due to the Blue gravel pit excavation location change. Therefore, we believe a traffic impact study for a relocation of excavation area should not be needed or required. If you have any questions or need anything further, please feel free to call me at (303) 228-2304. Sincerely, KIMLEY-HORN AND ASSOCIATES, INC. ".7. Curtis D.

County Road 104 after a fairly short distance then merges into County Road 103 (the "102 Access"). Based upon historical operations, the 82 Access accommodates approximately 95% of all the vehicular traffic generated by the Blue Pit. These locations are set forth within those maps contained within our present Application for Major Impact Use with Garfield County ("Amendment Application"). The 82 Access was permitted by the Colorado Department of Transportation ("COOT') under Permit No.396055 an March 21, 1996. This permit is attached. The 104 Access is a historical ranch access paint. The CDOT Permit for the 82 Access required the construction of acceleration/deceleration lanes for all 4 movement directions to and from the access, which have been in place since their construction in 1996. Sheets 2 through 6 of the existing permit lists 50 conditions which must be complied with. Almost all of these conditions are details concerning the design and construction of the accel/decel lanes. All of the 50 conditions have been complied with. The most important conditions are discussed below: Condition 5: Condition 6: Condition 13: Condition 14: No new property was dedicated for the right of way since the existing right of way was sufficient for the new accel/decel lanes. The final plat was the same as the pre-existing plat since no new right of way was needed. Full plans designed by a registered professional engineer at Schmueser Gordon Meyer were provided to CDOT as required and CDOT gave permission to proceed. Upon completion of the work, the engineer submitted "As Built" plans as required, showing compliance with all requirements. All other conditions of the installation were met. The access has been in operation since 1996 with no functional problems of any kind. 0304 Highway 133 • Carbondale, Colorado 81623 • (970) 963-9424 Page 2 April 21, 2010 Curtis Rowe Kimley-Horn and Associates, Inc. The COOT Permit for the 82 Access stipulates that no more than 110 acres of general Tight industrial use will supply the access point. Over the existing life of the operation as expanded under the Amendment Application, this condition (accessing no more than 110 acres)will always be fully complied with. The pit will not access the additional acreage requested under the Amendment Application for approximately 8 more years, and as this area is accessed later, lands will be reclaimed so that the 110 acres of industrial use is never exceeded. Lewicki and Associates has prepared an analysis showing the disturbance area over the life of the pit, which confirms that the 110 acres will never be exceeded. This analysis is attached. Current operations consist of one crushing operation and a concrete batch plant. No additional crushers or other operations are planned or requested under the Site Plan contained within the Amendment Application. The pit operations will remain the same for the expanded area. Traffic at both the access points, Highway 82 and 103 Road (approximately 5% of traffic), will not change, due to the pit expansion. Constituting as such merely a life extension of present pit operations, the Amendment Application will result in no additional construction activities and as such, does not put into issue aspects such as staging and storage areas, temporary access points, lane closures or traffic interruptions. There have never been any issues such as traffic bottlenecks, safety issues or any other issues during the entire time that the 82 Access has been used. Operations will remain the same so the historic traffic from the pit will not change if the Amendment Application is approved. Sincerely, M.

If Western Slope Aggregate is successful in obtaining approval of its present application for Amended Major Impact Review, this area will be expanded to 146.87 acres. As discussed, although the total mineable acreage will be increased, such increase because of contemporaneous reclamation and the use of permitted areas for buffering, the total industrial use area will remain well under 110 acres at any one time. See the scenarios below and attached maps for details. Current Disturbance 60.4 acres Permitted Disturbance 82.7 acres (after mining area 2 is mined out) This will not occur for 6-8 more years.

INTRODUCTION di,engineering dynamics Iincorporated This noise assessment report was prepared for Western Slope Aggregates under the direction of Ryan Ellis of Greg Lewicki and Associates and addresses noise emissions and control thereof associated with the proposed expansion of the Blue Pit Sand and Gravel MMine. The pit is located north of State Highway 82 and between County Roads 100 and 103 in Garfield County, Colorado. The address of the Blue Pit is: 0304 Highway 133, Carbondale, Colorado. The mining plan including drawings and maps necessary for the preparation of this Noise Assessment Report were provided to Engineering Dynamics Inc. by Greg Lewicki and Associates. Other maps and drawings showing equipment locations and access roads have been prepared by Greg Lewicki and Associates and are included in the application package. Topographical cross sections are included in the Applicant's submittal package. On Tuesday, April 28, 2009, Mr. McGregor visited the Blue Pit Expansion Area and was given an extensive tour of the site by Mr. D. Brown. Engineering Dynamics Inc. has prepared noise impact assessment analyses and reports for the surface and underground mining Industry since 1972. All of the work reported herein was performed by Mr. McGregor or under his direct supervision. Howard N. McGregor is a registered professional engineer licensed to practice engineering in the State of Colorado. Mr. McGregor holds Colorado Professional Engineer License Number 3928, which was obtained by examination. This report will show that the proposed operation can meet State and County noise standards by employing the mitigation measures described in this report. E.D.I. Job # C3785 Page 3 of 10 3925 S.

Community Noise Community noise has been addressed by the Federal Government starting with the U. S. Environmental Protection Agency, (EPA) "Noise Control Act of 1972". In concert with that act, state and local governments have enacted laws or ordinances regulating noise emission levels. Furthermore, these laws clearly define measurement methodology and decibel limits in scientific terms. Some laws do, however, include subjective assessments, which are considered outside of rigorous scientific evaluation and for this reason can be highly variable. Subjective assessments or considerations will not be addressed in this report for that reason. B. State of Colorado Noise Law Section 25-12-103. Maximum Permissible Noise Levels §(1) Every activity to which this article is applicable shall be conducted in a manner so that any noise produced is not objectionable due to intermittence, beat frequency, or shrillness. Sound levels of noise radiating from a property line at a distance of twenty-five feet or more therefrom in excess of the dB(A) established for the following time periods and zones shall constitute prima facie evidence that such noise is a public nuisance: §(2) In the hours between 7:00am and the next 7:00pm, the noise levels permitted in subsection (1) of this section may be increased by ten dB(A) for a period of not -to -exceed fifteen minutes in any one-hour period. This paragraph in the State of Colorado Noise Law has been interpreted to mean that this 10 dB increase can occur once and only once during the daytime hours of 7:00am to 7:00pm and never during the nighttime hours. §(3) Periodic, impulsive, or shrill noises shall be considered a public nuisance when such noises are ata sound level of five dB(A) less than those listed in subsection § (1) of this section. Examples Periodic — pile drivers, impact wrenches, punch presses, jack hammers and compaction equipment. Impulsive — firearm, fireworks, blasting, high pressure venting. Shrill — sirens, metal forming, warming devices. §(5) Construction projects shah be subject to the maximum permissible noise levels specified for industrial zones for the period within which construction is to be completed pursuant to any applicable construction permit issued by proper authority or, if no time limitation is imposed, for a reasonable period of time for completion of project. This section of the law has been interpreted to include mine development as construction. Such construction would include access roads, top soil removal and storage, set up of stationary equipment such as crushers, screens and engine generators, installation of utilities and construction of earthen noise barrier berms. Section 25-12-104 Action to Abate The entire section was amended in 2008 and made effective on August 5, 2008. The last sentence of this section now reads: The court may stay the effect of any order issued under this section for such time as is reasonably necessary for the defendant to come into compliance with the provisions of this article.

Garfield County Garfield County has no ordinance or regulation addressing noise in general and relies upon Colorado Revised Statutes, Title 25, Article 12,"Noise Abatement" for determination of compliance. However, Garfield County has a supplemental Gravel Extraction Regulation and Section 5.17.03 titled "NoiseNibration" addresses noise and vibration. This Garfield County Regulation resolves conflicts that have occurred previously into the interpretation of CRS 25-12 section 103 as to whether the noise limits are determined by the zoning of the noise emitter property or the zoning of the receiver property. The Garfield County Regulation clearly states in 5.17.03 § (2) that the noise limits are determined by the zoning of the receiver property. The Garfield County Supplemental Gravel Extraction Regulation and the Colorado Noise Law are silent on another factor which is the setting of the sound level meter used during the measurement of the noise. Most sound level meters have two settings available when using the A -weighting; the settings are dB(A) fast and dB(A) slow. The dB(A) fast setting always indicates a dB(A) value that is equal to or greater than the dB(A) slow setting. The difference can be as great as 10 dB(A) for non -steady noise sources such as a dozer or front-end loader. For the stationary equipment such as crushers, vibratory screens and conveyors, there is essentially no difference between the dB(A) fast and the dB(A) slow because the noise is constant or steady. However, the dB(A) values used in the analysis section of this report (Section IV) are the maximum, either measured or provided by the equipment manufacturer. They are not the average decibel value, which could include minimum noise levels. D. Zoning of Adjacent Land 1. North A residence is located 868 ft. north of the boundary of Mining Areas 3 and 4 just north of the "Y" intersection of County Road 103. The residence is at an elevation of 6180 ft. and due south at the pit boundary the elevation is 6158 ft. There are two residences north of Mining Area 5; one is at a distance of 880 ft. and at an elevation of 6180 ft. The second residence is at a distance of 712 ft. and at an elevation of 6175 ft. All three residences are north of the irrigation ditch/pipe. There is a 50 ft. offset to the south from the edge of the permit boundary to the mining excavation. 2. South Residential property is located to the south and across Hwy 82. The distance to the nearest residential property from the Expansion Area is about 430 ft. and the distance from the mining limit boundary is 480 ft. The residential property is lower than the mining limit boundary by about 80 ft. therefore the line -of -sight between these two locations is broken. This is shown as cross section A- A' in the drawing titled "Western Slope Aggregates, Blue Pit, Visual Map 2, Cross -Section Map. 3. East Due east of the existing mine and the mine Expansion Area is the Garfield County Waste Disposal Area. This parcel of land has not fully been reclaimed and in all probability will never be rezoned to residential. It could be rezoned to industrial. Additionally there is an enormous topsoil stockpile on the eastern portion of Mining Area 1 that will remain in place until the mine nears its final reclamation stage. 4. West There are residential and farming structures located 850 ft. northwest from the northwest corner of the Mining Area 5. In this northwesterly direction, there are at the present time no significant natural changes in elevation or other natural obstructions that would be barriers or obstructions to noise coming from the mine. There may be, however, during mine development and production noise barriers made of overburden or mine product. E.D.I. Job # C3785 Page 5 of 10 3925 S.

EQUIPMENT INVENTORY AND NOISE EMISSION LEVELS Table 1 presents a list of the equipment that will be in operation at the pit during development, mining and reclamation. The noise emission levels for the equipment listed in Table 1 is presented as so many dB(A) at 100 ft. This avoids the confusion associated with the use of the sound power level dB. The 100 ft. dB value can be used to determine the noise level at other distances by use of a simple calculation using logarithms. However, the calculation does not include the effects of terrain, vegetation, vertical thermal gradients in the atmosphere and wind and should be used only for initial analysis purposes. dI enco�ootu d Description Backhoes Doze0 Front -End Loader Front -End Loader Qty 2 1 2 2 Table 1 Mine Site Construction and Development Mfg.

Approach The noise assessment analysis presented in this section of the report is based upon the following two requirements. 1. During development (construction) of the amended pit area the daytime noise limits shall not exceed the maximum allowable for Industrial Zoning of 80 dB(A) at a distance of 25 ft. beyond the Blue Pit Expansion property line in all directions CRS 25-12-103, §(5). 2. During production in the expansion area, the noise limits shall not exceed the maximum allowable for Residential Zoning of 55 dB(A) during the daytime and 50 dB(A) during the nighttime at a distance of 25 ft. beyond the pit property line or at the receptor, CRS 25-12-103. B. Mine Development During mine development, which is considered a construction activity, the noise limits are as detailed in CRS 25-12-103; (5), which limits the maximum permissible noise levels specified for industrial zones, that is: 80 dB(A) form 7:00am to 7:OOpm. Mine development will begin in already worked Area 1 then sequentially onto Areas 2, 3, 4 and 5. Overburden, which ranges from 4 to 7 ft. in depth, will be removed with the front end loader. The maximum noise level to the north, south, east and west that will occur when there is a direct line -of -sight and when the front end loader is at the closest property line are presented in Table 2. dI engineering ncorporated dynamics Table 2 Maximum Noise Level during Mine Development Front End Loader — 76 dB(A) at 10.0 ft. Direction Receptor Noise Source Location Maximum Noise Level — dB(A) N Home North Edge of Areas 3 and 5 _ 57 N Home North Edge of Areas 3 and 5 57 N/NW Home Northwest Corner of Area 5 59 S Homes Directly South of Areas 2 and 4 62 E Property Line Eastern Property Line 66 W Property Line Western Property Line 70 It can be seen in Table 2 that under the worst case conditions when the front end loader is at the western mining edge and close to the property line that the noise level is 10 dB(A) less than the 80 dB(A) permissible level specified in CRS 25-12-103 § (5). This noise level occurs only at the western mine boundary. In all other directions the noise levels are much lower. Also, the duration of these noise levels will only be several days. C. Initial Mining After mine development is completed and production commences the noise limits shall not exceed the maximum allowable for Residential Zoning at a distance of 25 ft. beyond the Blue Pit property line or at the receptor. Excavation of material' will start at the east face of the initial expansion area and the raw material will be transported to the jaw crusher bin by the front end loaders. During initial production the crushing and screening plant will remain at its present location and will always be below grade, The 55 dB(A) noise contour or footprint will not extend beyond the top edge of the mine face to the north, south, east and west. Elevations may be seen on the Site Plan, E.D.I. Job # C3785 Page 7 of 10 3925 S. Kalamath St., Englewood, Colorado 80110 • voice: 303-761-4367 • fax: 303-761-4379 D. Processing Plant — Noise Emissions The processing plant works as follows: The front-end loader (CAT988) will dump the raw rock material into the jaw crusher feed bin. The crushed rock and fines will then feed to vibratory screens located under the jaw crusher. Rock of the selected size will be washed and go via conveyor to storage piles. Rock that is too large will be transported via conveyor to the cone crusher where the material is reduced in size. From the cone crusher, the material goes back to the vibratory screens, where it is separated by size, washed and then conveyed to storage piles. engineering dynamics ethincorporated The processing plant will initially remain at its present location and then move in a westerly direction but remain at the same level as the existing pit floor, which is 6110 ft. Table 3 presents the stationary and mobile equipment that make up the processing plant and the noise level of each. At distances greater than 100 ft., the processing plant can be mathematically treated as a single noise source having the total noise emission of 80 dB(A) at 100 ft. as presented in Table 3.

Front -End Loader CAT988 76 Jaw Crusher Cedarapids 74 Cone Crusher JCI 71 Conveyors Misc, 65 Vibratory Screen -- 70 Total Combined Noise Level 80 (1) See Table 1, which details all of the equipment operating at the pit. If the processing plant and the receptors (north, south, east, west) were all at the grade level or in the direct line -of -sight, the 55 dB(A) noise level would occur at a distance of 1775 ft. in all directions. The reduction of noise from the processing plant due to distance and the barrier effect of the intervening terrain are presented in Table 4. Table 4 Processing Plant Elevation —6110 ft.

Kalamath St., Englewood, Colorado 80110 • voice: 303-761-4367 • fax: 303-761-4379 engineering d a e dynamics incorporated It should be pointed out that the terrain reductions occur when the receptor is beyond the upper edge of the pit and the line -of -sight from the receptor to the processing plant is broken. Otherwise, there is no reduction in the noise from the plant at that receptor location due to the pit wall. Also, the data presented in Table 4 are when all of the equipment is in operation including the front end loader. Such a situation would not be continuous because, for example, the front end loader would be away from the crusher bin when it was scooping up another load of rock. E. Mine Site Haul Trucks Mine site haul trucks are high capacity units capable of hauling up to 30 ton loads. The trucks will transport material to storage areas near the processing plant where the front end loader will pick up the material and dump it into the jaw crusher bin. The trucks will also be used to transport over burden to storage areas. The mine site haul trucks will be limited in speed to 15 mph or less and will produce 76 dB(A) at 100 ft. and 55 dB(A) at an unobstructed distance of about 1000 ft. The only time this condition would occur is when the trucks were transporting overburden to storages areas during development of the Expansion Area during which time the 80 dB(A) permissible noise level, CRS 25-12-103 §(5), would occur at distances of less than 104 ft. During mine production the trucks will initially start out at about 10 ft. below grade and the 55 dB(A) distance would be at 700 ft. As mining progressed the trucks will be further below grade and the distance to the 55 dB(A) will become less and less and eventually be pulled in to the pit edge. P. Highway Haul Trucks Highway haul trucks will be loaded with rock products or concrete and leave the pit via the access road and onto Highway 82. Once the trucks are on Highway 82, they will be required to not exceed the permissible noise limits of CRS 25-12-106 of 86 dB(A) at 50 ft. at speeds of less than 35 mph. Customer haul trucks that exceed the 86 dB(A) may be denied access to the pit until they have been repaired. There is a change in Crs-25-12-107 that is effective, July 1, 2010 and is as follows: (1) Counties or municipalities may adopt resolutions or ordinances prohibiting the operation of motor vehicles within their respective jurisdictions that produce noise in excess of the sound levels in decibels, measured on the A" scale on a standard sound level meter having characteristics established by the American National Standards Institute, publication S1.4 — 1971, and measured at a distance of fifty feet from the center of the Fine of travel and within the speed limits specified in this section. This change removes the requirement that this section is applicable to of highway vehicles such as those within the Blue Pit Expansion areas. However, Garfield County can still enact noise limits for highway haul trucks that are less than those in CRS -25-12, for example; haul trucks on Highway 82. G. Reclamation Topsoil may be taken from the topsoil storage areas to the mined area using the dozer, front end loader and haul truck. Distribution of the topsoil will be done with the front end loaders. Smaller equipment such as a skid steer may be used for ditching and seeding. Most of the time during reclamation, the equipment will be below grade. E.D.I. Job # C3785 Page 9 of 10 3925 S. Kalamath St., Englewood, Colorado 80110 • voice: 303-761-4367 • fax: 303-761-4379 ■ engineering dynamics edi incorporated V. CONCLUSIONS AND RECOMMENDATIONS 1. Noise emissions during mine development (construction as defined in CRS 25-12-103 § (5) will not exceed 80 dB(A) at 25 ft. beyond the existing or amended pit boundary. 2. During mine development noise emission levels from the front end loader at the homes to the north and south will be less than 62 dB(A) when the front end loader is at grade level and at the closest property line. At all other locations that do not abut to the mining boundary the noise level during development will be less than 60 dB(A). 3. During mine production in any of the five mining area, the noise level from mobile equipment occurring at the homes to the north, northwest and south will be less than 55 dB(A) and intermittently lower. This condition will only occur during the initial mining operations, as mining progresses and the mobile equipment goes deeper and deeper, the noise level will decrease. 4. Noise levels from the processing plant will always be less than 46 dB(A) at the homes to the north, northwest and south. The process plant will always be at an elevation of 6110 ft (the pit floor), even when it is moved in an easterly direction. 5. All backup alarms will be of the white noise type and will be adjusted during installation to meet all regulatory requirements. 6. Customer haul trucks that exceed the noise limits specified in CRS 25-12-107 may be denied access to the pit until they have been maintained and are in compliance. 7. Noise measurements will be taken once the pit expansion area of the pit is in production to verify compliance with CRS 25-12-103. Measurement results will be detailed in a report certified by a Professional Acoustical Engineer registered in the State of Colorado. EL I. Job # C3785 Page 10 of 10 3925 S.

The Blue Pit is separated from the Roaring Fork River Valley by an 80' tall natural slope which remains after removing the gravel from an elevated alluvial terrace. Western Slope Aggregate has a lease with the landowner which allows them to conduct mining operations north of this slope. The gravel deposit which is being mined was deposited by the Roaring Fork River and is greater than 100 feet thick. The groundwater level limits the mining of the deposit at approximately 90 feet deep in the expansion area and 60 feet in current permit area. The groundwater surface is estimated from the existing excavation and by exploration drilling conducted in the area. The site has been mined since 1981 under the state Reclamation Permit # M-1981-207. The site has been mined the site the early 1980's and has expanded to an annual production rate of approximately 400,000 tons per year. The existing permit area is 82.70 acres and approximately 25 acres is still able to be mined until the expansion area is entered. Approximately 60 acres of additional gravel mining is included in the expansion area. The existing reserves will be exhausted in Iess than 8 years and Westem Slope Aggregate wants to secure reserves further into the future. The expansion area is located directly adjacent to the existing operation and is shown the Site Map located in this Visual Impact Report. Since Western Slope Aggregate has operated the Blue Pit, there have been no major complaints or violations pertaining to the visual impact of the mining operation. Western Slope Aggregate realizes that there are visual impacts associated with the expansion of the Blue Pit, especially to the homeowners north of the pit. Through the mitigation measures outlined in this report, mining of the expansion area will minimize visual impact and provide an excellent reclamation plan for the final site. Visual Map 1 shows the site in relation to the surrounding area. Features of the surrounding area are shown. It also shows key picture locations discussed in this report. Page 1 Mining Plan Map C-1 shows the current status of the site where considerable mining has taken place under the approved permit. The map also shows the extent of the mining approved in the existing permit, which is now divided into 5 phases, Mining Area 1 is the current permitted area east of the Basin Ditch, Mining Area 2 is the previously permitted but west of the Basin Ditch. The current approved plan allows 2:1 final slopes in all areas, Mining Areas 3, 4 and 5 are proposed areas of new mining under the 2009 expansion plan. All of these areas can be seen on Map C-2: Mine Flan Map. Minimization of visual impact to the homes north of the pit is the driving force of the entire plan sequencing. The plan is to continue moving west at the southern edge of the mining limit, while performing most activities from the pit bottom, making most of the activities invisible. This includes the actual mining with a dozer, loading of the raw gravel with a front end loader and trucking the gravel to the plant facilities in Mining Area 1. As mining moves to Mining Area 2, the pit bottom will likely be lowered from an existing depth of approximately 60 feet to 90 feet. This is entirely based on what is believed to be the level of groundwater in the area, which is the limiting factor in the pit depth, since the operation cannot expose groundwater. The southern face of Mining Area 2 will be mined at a slope of 1.5:1 and the visible portion of this slope will be temporarily reclaimed as the pit is lowered. In this way, the homes to the north will primarily see a reclaimed slope on the south of the pit. Once the pit reaches its final depth, the operation will move north, always working from the pit bottom. As this is done, the length of temporary vegetated slope will be expanded, As the pit bottom extends north, the south slope will be gradually restored to a 3:1 slope, using overburden, processing fines and imported fill. The actual slope will be approximately 3.1:1, since flat drainage benches will be installed on the slope to prevent later erosion. Visual Map 2 shows a cross section depicting all the items discussed above. During the extension of mining to the north, topsoil and overburden will be stripped on the original surface, in advance of the mining operation. This will be visible, but it will be done in rectangular fashion, to look similar to a plowed field, which is done from time to time on the existing irrigated field. This topsoil and overburden stripping will take place approximately one week per year. Page 2 • • • Reclamation Plan Basics The reclamation plan is based on the following main items: 1) Keeping the concrete plant operation in the existing east area of the pit. This plant is not visible to any of the homeowners north of the pit, since it is at the pit bottom and east of the homeowners view. 2) Reclaiming Mining Area 1 sideslopes to rangeland, at a 2.5H:1 V slope. 3) Restoring irrigation to the flat bottom portion of the expansion area of the site 4) Reclaiming Mining Areas 2, 3, 4 and 5 sideslopes to rangeland, using the newly proposed slopes of 3:1. A justification of these slopes being steeper than 5:1 is given in the Section 7- 840 Gravel Extraction Regulations - Section H of the 2009 expansion plan application. 5) Maintaining the Basin Ditch and Spring Ditch through the property. 6) Keep the mine operation and most reclamation activities well below the visible sight line of the homes to the north by utilizing the depth of the deposit and the mine sequencing to minimize the visual impacts. 7) All reclamation activities will be done in phases so that the visual impact to the north homes is minimized. 8) The north facing slopes of the pit will be temporarily reclaimed and irrigated to lessen visual impacts to the homes to the north. Page 3 • • • Evaluation of Visual Impacts On November 4 of 2009, several pictures were taken from various areas surrounding the Blue Pit to determine the areas that would have a visual impact due to the operations of the Blue Pit. These areas were broken down into three major areas: 1) Highway 82, 2) the Roaring Fork River Valley and 3) the homes north of the pit. Locations of the pictures included in this report are shown on Visual Map I - General Location Map which is included in this report. Visual representations of the expansion areas have been created using a baseline topographic map in AutoCad, which was then modified using 3D grids for the mining and reclamation of the expansion area. These visual representations were made to determine the impacts from the three sensitive areas. Sensitive Area #1 - Highway 82 Highway 82 is a heavily traveled road by Garfield residents, commercial vehicles as well as tourists. As seen on the General Location Map, this area needs to be evaluated for visual impacts due to the expansion of the Blue Pit. The view to the north (looking towards the Blue Pit) is shown in the next three pictures. The undisturbed southern face of the natural slope is approximately 50-90 feet high, which is vegetated with mature trees and grasses. There is no part of the expansion area (or the existing operation) that is visible from Highway 82. The access road is the only visible part of the operation and will be kept in its existing condition as well as truck traffic. The locations of all pictures used in this report are shown on the General Location Map in this Visual Impact report. All pictures were taken on November 2, 2009 by Greg Lewicki, P.B. with a Canon G10 digital camera using the equivalent of a human eye view zoom level. Page 4 • • • v vs vs dal t3 7D OD co) 7J Q 7.a C'S y Wtct �. • 77$ Cto LL � I v CV �— au ▪ C? y w�,A Sensitive Area #2 - The Roaring Fork River Valley The Roaring Fork River Valley does not have a visual impact from the expansion area since the expansion area is not visible from the valley floor. Since the raining area is basically an excavation of the upper gravel terrace, and the outside portion (on the south) of this terrace will be left intact, the operation cannot be seen from the valley. The only part of the existing operation that is visible from the valley is the topsoil stockpile at the far eastern edge of the permit area. This existing stockpile, shown on Picture 5, will be vegetated for most of the entire life of the operation. It will be used to reclaim the site after mining and backfilling activities have been completed at the end of the mine life. As stated before the berm left on the southern side of the pit provides a barrier to the operation. Also areas on the southern side of the valley that are elevated similarly to the Blue Pit are industrial and can not see the operation because it occurs behind the berm and below the natural grade. The river valley is also heavily vegetated with mature cottonwood trees as shown in the following pictures. Page 7 • • • Sensitive Area #3 - Homes North of the Pit Approximately one dozen hornes were constructed on a hill to the north of the Blue Pit expansion area and have a direct view of the expansion area. The visual impacts will be minimized through the use of the natural terrain, phasing the operation, contemporaneous reclamation and the use of temporary seeding as well as final reclamation seeding. The natural terrain of the area of the Blue Pit is a relatively flat terrace elevated approximately 50-90 feet above the valley floor and Highway 82. This flat terrace extends further to the north for approximately 200-700 feet, where some ranch buildings are located. These buildings are owned by the property owner of the pit. The homes are located on a hill further to the north overlooking the pit. These homes vary in elevation but are approximately 100 to 300 feet higher than the elevation of the gravel terrace. The homes are also located at a distance of approximately 2000 to 3000 feet north of the terrace to be mined. Picture 6 shows some of the activities on the western portion of the existing disturbance. Many gravel stockpiles and the wash plant are visible. As described in the mine plan, the pit floor will move west from Mining Area 1 and much of the existing disturbance will move to the pit floor, where it will be invisible. This will actually be an improvement over what is now visible. For an initial period of approximately 3 years the wash plant will be located north of Mining Area 1 in the existing horse pasture. The wash plant will be moved to the pit floor once ample room is available. Several pictures were taken from the road leading to theses homes north of the planned expansion area. The worst case visual scenarios are shown in Pictures 6 and 7, where the gravel terrace is visible, representing the view from the homes. Picture 7 location represents the worst case visual location since it the highest point where homes are located while at the same time, the operation is visible. The access road continues north but the terrain levels out and thick stands of trees prevent the homes from seeing anything below. Western Slope Aggregate understands the view from the homes is very attractive, with Mount Sopris in the background. Modified versions of these pictures have been included to show what the site will look due to mining. Picture 6 — Zoomed In View is an intermediate stage looking east of the farm road splitting the property. Picture 6 Normal Eye View shows the same area as currently exists but at a normal human eye view. Picture 6 —Normal Eye View Modified shows the effects of rnining this area. This picture is crucial because raining activity will be taking place at pit level but it is not visible due to the depth and the angles involved. Visual Map 2 shows this in the Cross Section. Picture 7 is from a different location on the road, which shows the majority of the expansion area to the west. Picture 7 -Modified shows the effects of mining this area. The line of site angle is fairly shallow which prevents the homeowners from seeing the pit floor when mining is taking place. During topsoil and overburden salvage operations, the equipment will be at the same grade as the existing fields and the equipment will be visible. Topsoil and overburden salvage will only occur approximately one week per year and will therefore not have a significant visual impact. Also, the topsoil and overburden operation will be performed in rectangular form, which is very similar to the way that the current irrigated fields are managed for the irrigated alfalfa. These Page 11 fields are disked at intervals to relieve soil compaction. The natural terrain and site angle are shown in the Visual Map 2 - Cross Section which is included in this section. The expansion area will be phased to limit the total disturbed area at any one time. The processing will be conducted within the existing operation. The expansion area will salvage topsoil and overburden each year to minimize the amount of area disturbed at any one time. The phases are also oriented so that the longest distance is in the east west direction to help shield the pit from the homes. The external slopes of the expansion area will be mined to 1.5H:1V and will therefore need to be backfilled prior to final reclamation seeding. As areas are fully mined out, the external slopes will be backfilled with overburden or imported fill material to a final reclamation slope of no steeper than 3H:1V. Temporary seeding will be conducted on the 1.5H:1V slopes that are visible from the homes north of the Pit. Theses slopes will be seeded in the fall with a seed mix that is designed for the Carbondale climate and which will provide good visual cover. This temporary reclamation will be irrigated in a supplemental fashion to ensure that it provides the visual protection for the homes to the north. This will be accomplished with a water truck spraying the slope to supplement natural precipitation. Theses slopes should be of similar color and texture of the irrigated pasture adjacent to the expansion area. Subsequent phases will not be disturbed until the temporary ground cover is established on the slope that will become visible. See the Visual Map 2 - Cross Section for details of the seeding schedule. As described in the mine plan, as the operation progresses north, the south slope can be backfilled to its final slope and will be reclaimed using the final rangeland seed mix. As bottom areas are mined, graded and topsoiled, these areas will also be reclaimed on an ongoing basis. The final seed mixes will be placed on all final graded and topsoiled areas. The slopes will be seeded with a rangeland mix that will replicate the native slopes that have not been irrigated. The flat bottom will be irrigated and will be seeded with the same seed mix that the landowner uses on the existing irrigated pastures. This is primarily alfalfa.

The area of concern is the rural development of approximately 12 homes located north and uphill of the pit expansion area. Western Slope Aggregate has spent considerable time in developing a mining and reclamation plan which is entirely based on minimizing impacts to the homeowners living north of the pit. This plan provides temporary reclamation of the visible south slope, which together with the irrigation of this slope, are mitigation items that have not been done at any other pit in Colorado, to the best of our knowledge. The costs of these items are solely for the benefit of the homeowners, since the slope will later be changed from 1.5:1 to 3:1. Considerable effort has also been placed in the mining being expanded from the pit floor, which, due to its depth, will keep most activities invisible. The sequence of the mining is also entirely based on reducing visual impacts.

The 98 -acre parcel is located in Section 25, Township 7 South, Range 88 West (Figure 1). The following analysis addresses significant wildlife uses currently occurring on the Property, and evaluates the condition and functional values ofthe habitat types found on the site. The report further addresses potential short- and long-term effects of the proposed action on the identified wildlife resources, including specific evaluations for species of concern. 2.0 Proposed Action Western Slope Aggregate, Inc., (the "Company") currently operates an aggregate mining operation on land immediately adjacent and east of the study area, which has been in production since 1981. The Company has proposed an expansion of existing gravel mining operations westward to include the Property in question. The proposed expansion would allow the Company to maintain existing production levels as mining operations are completed on the current mining area and that area is abandoned reclaimed. Gravel extraction from the existing area is expected to continue until reserves are depleted. It is anticipated that expansion to the new mining area would be implemented in 4 phases (Phase 2A, 213, 3A, 313), with production expected to continue for approximately 12 years (Figure 2). Operations would be primarily on existing hay fields, though some minor re- grading could occur on a portion of the pinyon -covered hillside in the northeast corner. It is anticipated that a number of mitigation measures might be implemented to protect open space for wildlife and enhance habitats for a variety of wildlife species upon completion of mining operations. Those mitigation measures are discussed in a later section. 3.0 Methods The wildlife assessment presented herein was based on the following: a) A review ofthe Colorado Natural Heritage Program (CNHP) database for Garfield County. b) A review of current Colorado Division of Wildlife (CDOW) Natural Diversity Information Source (NDIS) species distribution maps and GAP analysis. c) A review of Natural Resource Conservation Service (MRCS) soils data. d) April 2009 field surveys of the Property. e) The author's extensive field experience with a variety of wildlife and habitat - related matters in this region. 4.0 Study Area Description Site Description The project area consists of approximately 98 acres of gently rolling, upland habitats which have been almost entirely converted to irrigated hay production. The one exception is the far northeast corner which harbors a relatively steep hillside covered with native pinyon and juniper forest and some sagebrush. The site ultimately drains into the Roaring Fork River to the south (Figure 3). The Property was historically used for agricultural production, and continues to be used for irrigated hay production and fall/winter pasture for cattle. The Property has been well-maintained with irrigation systems in good working order, fields generally free of weedy species and fences in good repair. There were no significant hazards to wildlife movement or habitat use discovered on the Property during the site visits. Lands adjacent to the Property include more irrigated hayfields to the west and east and a steep bluff covered by native sagebrush and pinyon pines to the south. To the north is an irrigated hayfield that abuts a mesa on which a small subdivision resides. Vegetation on the hillside is mainly native pinyon and juniper forest and some small areas of sagebrush. Vegetation The Property consists almost entirely of irrigated hay, with the most prevalent species consisting of Smooth brome (Bromus inermis), Orchardgrass (Dactylis glomerata), Kentucky bluegrass (Poa pratensis) and Dandelion (Taraxicum officinale). There are also small contingents of alfalfa (Medicago sativa), Sweetclover (Melilotus officinalis), Common plantain (Plantago major) and Western salsify (Tragopogon dubius) amid the hayfields. Some fields (Phase 3B site) have been recently planted solely to alfalfa (Medicago sativa) with a nurse crop of oats (Avena fatua) to get the planting established. The only non -hay -producing areas are roadside ditches, the edges of the existing mining areas and the far northeast comer which is comprised of a mountain toe -slope covered with pinyon juniper forest. in these non-agricultural locations a variety of plant species can be found, including Crested wheatgrass (Agropyron cristatum), Slender wheatgrass (Agropyron trachycaulum), Western wheatgrass (Agropyron smithii), Western yarrow (Achillea millefolium), along with more weedy species such as Ragweed (Ambrosia psilostachya), Tumblemustard (Sisymbrium altissimum), Curlycup gumweed (Grindelia squarrosa), Kochia (Kochia scoparia), Curled dock (Rumex crispus) and Russian thistle (Salsola iberica). Undisturbed upland areas to the north of the Property (from the subdivision and beyond) are dominated by Pinyon pine (Pinus edulis), Utah juniper (Juniperus utahensis), Big sagebrush (Artemisia tridentata), Douglas rabbitbrush (Chrysothamnus viscidorus), Gambel's oak (Quercus gambelii) and Mountain mahogany (Cercocarpus montanus). The understory consists primarily of Western wheatgrass, Kentucky bluegrass, Prickly pear cactus (Opuntia compressa), Galleta-grass (Hilaria jamesii) and various penstemons (Penstemon spp.). There are no riparian areas nor wetlands found anywhere on the 4 • • Property, though there is a small stand of cottonwoods about % mile west of the Property where it is reported that eagle's sometimes perch during the winter months (Company staff, pers. comm.). A list of plant species found on the property is provided in Table 1. Tahla 1. Common nlants found on the Western Slope AgEregate Parcel.

These soils ranged from 2-6% slope and are deep, well -drained soils with moderate permeability and high water capacity. Surface runoff is medium and erosion hazard is slight on the Empedrado soils. These soils are well-suited for hay production, small -grain crops and pasture. Records indicate this soil type can annually yield 5 tons hay/acre or 90 bushels of barley/acre under proper management. It has few limitations, but performs best if a crop residue is left covering the field over the winter and with adequate fertilizer added annually. 5.0 Significant Wildlife Use of the Property Records searches, interviews with CDOW personnel and the site visits revealed a number of wildlife species known to use the Property. Despite the generally monocultural nature of most of the vegetation in the area, a reasonably diverse array of species frequent the Property, including elk, mule deer, coyote, cottontail rabbit, and other small mmals, A variety of bird species also utilize the area, at least seasonally, including a wide range of songbirds and raptor species. However, despite the number of species known to use the area, most are notably habitat generalists. There are no special habitat parameters nor specialized species seeking specific habitat functions on the Property. Time and space constraints dictate that this analysis will focus on those wildlife species that are of significant ecological, economic, regulatory or political importance. Other species or ecological elements assuredly occur on the Property, but are omitted in this discussion due to one or mare of the following: 1) they will not be significantly impacted by the proposed action; 2) they are not specifically regulated by local, state ox federal law or code; 3) their life cycle and/or habitat use criterion do not make them reasonable indicators of probable effects to other wildlife species. Several Federal and State -listed Threatened or Endangered species and species of special concern, which have been known to occur in Garfield County were considered but precluded from use in this analysis for a variety of reasons. Most commonly they were precluded due to the lack of suitable habitat in the study area. A complete list of these species along with their legal status and reason for dismissal from further review are shown in Table 2. Three species were selected for analysis because of their regulatory status, sensitivity to human activities, known use of the study area, limited habitat resources in the region and/or their ability to serve as indicators of probable effects to a variety of other wildlife species. Each species is discussed, complete with known -use history, special habitat availability and likelihood of continued future habitat capability for the species. These include mule deer, elk and bald eagles. 6 • • • Table 2: Threatened, Endangered and Sensitive species precluded from detailed analysis on the Western Slone A ere ate Parcel.

Mule deer are known to utilize the site throughout the year. The Property is not considered to be a production area but is shown as normal summer range for the species. There are no migration corridors mapped on the site by CDOW. However, the Property is listed as a Winter Concentration Area, which areas are defined as locations that harbor 200% higher densities of anirnals than surrounding areas of defined winter range in the five average winters out of ten, The entire Property is also mapped by CDOW as Severe Winter Range for mule deer, which is defined as the area on which 90% of the animals may occur when annual snowpack is at its maximum and/or when temperatures are at their lowest during the worst two winters out often. CDOW considers such sites as critical habitat for the species and gives these areas the highest habitat priority ranking for both deer and elk. However, because the Property has been cleared of all native shrub species and is managed as an irrigated hayfield, forage available for deer during the winter season is extremely limited, and particularly so under the severe, deep -snow circumstances indicative of CDOW's definition of critical winter conditions. Further, the size of the irrigated fields also makes the area less attractive for deer due to the flat terrain and distance from security cover. That said, deer do make some use of the hayfields throughout the year so Tong as snow cover remains shallow enough and uncrusted to permit them to forage. Generally, however, deer make notably less use of the Property than do elk. Elk are known to utilize the area fairly regularly, mainly from mid -fall as they seek refuge during hunting seasons, and throughout the winter months as long as snow cover remains light enough to allow them to forage. Elk can tolerate deeper, crustier snow surfaces than deer, and can also persist on a lower -quality diet, which explains the relatively higher use levels by elk noted in the area. However, though elk use the area more than deer, this does not imply that elk use is significant in the regional context. Given the amount of existing development and presence of the county road through the valley, much of the elk utilization of the area is done nocturnally as the herds seek to avoid human interaction, though they can occasionally be found on the Property in daylight hours. There are no mapped summer range, production areas or migration corridors for elk on the Property, and surprisingly, none of Property is mapped as any kind of winter range at all by CDOW. This is surprising in that CDOW typically maps general winter range with a fairly broad stroke and the bulk of elk use on the Property clearly occurs during the winter months. Since elk are generalist grazers, the lack of the native shrub component over much of the site and the dominance of irrigated grass hay does not render the rangeland as unsuitable for them as it does for deer. However, like the deer, elk require some areas of security cover and adequate travel corridors in order to utilize the site, and the broad expanse of open forage and lack of security cover may be 8 the reason CDOW does not include this site in its winter range mapping. if subdivision development becomes more dense to the north and associated daily human activity levels increase, the site will become less attractive to elk. Bald Eagle: This species was selected because it is listed as a State Threatened species and because they select relatively quiet, undisturbed riparian sites for nesting, and they require healthy aquatic ecosystems to provide adequate food resources. As such, they are an excellent indicator of the relative health and viability of many other species in the area. There are no Bald eagle nests known to occur on the Property, and the nearest active nest site is over 30 air -miles away from the Property on the Colorado River itself. There are two known winter roost sites bald eagles frequent along the Roaring Fork River just southwest of the Catherine Store. Employees of the Company also indicated that they have seen bald eagles flying in the vicinity during winter months, which would be expected due to the relative proximity ofthe Roaring Fork corridor and much ofthe valley being mapped as winter foraging habitat for the species. However, there are no critical habitat parameters for this species on the Property. The scarcity of mature cottonwoods or other tall tree species suitable for eagle nest sites, the abundance of roads and human activity already taking place in the area and the distance from the Roaring Fork River makes this a very unattractive location for nesting or roosting. The plethora of mature cottonwoods present along many miles of the Roaring Fork river corridor provide numerous adequate perches for hunting or roosting as well as nest sites along the river, which supplies far more productive habitat for this species than anything found on the Property. 6.0 Potential Effects of the Proposed Project The proposed project will result in significant surface disturbance of the relatively level hayfields on the Property. Gravel extraction requires removal and stockpiling of topsoil and overburden subsoils, and the mining itself removes aggregate materials permanently, changing the contours of the site in perpetuity. The direct physical effects to existing habitat are clear: open space, forage production and overall habitat availability will be significantly decreased on the Property during mining operations. Indirect effects include dust and particulate emissions, noise pollution and potential traffic collisions with wildlife. However, the effect of this habitat impact may be limited to the temporal effects of the mining activity, which is already occurring_ Reclamation plans include restoring the Property to agricultural production at the conclusion of mining operations, which obviously limits these impacts to the lifespan of mining activities. For the purposes of this report, it is true that the Property will experience a loss of habitat value for deer and elk, though less so for bald eagles, during the productive lifespan of the pit. It should be noted, however, that both the direct and indirect impacts discussed above will occur in phases on a 98 -acre parcel of marginal, open habitat. Such an impact will clearly be minor when viewed in a regional habitat context. 9 • • • These cumulative changes will likely decrease suitability of remaining habitat for most species, though prolific, adaptable species such as cottontail rabbits, red fox and a number of songbird species may persist or even increase in abundance. Potential effects and opportunities posed by the project for the key species identified in Section 5 are discussed below. Mule Deer and Elk: Since both mule deer and elk make primary use of the Property during winter months, and since winter habitat has been identified as the critical component for herd sustainability in much of the State, the proposed development will likely have some minor negative effects to both species. However, since the existing habitat consists of irrigated hay fields, the Property is of limited value as winter range for these species in any event. Mitigation measures that promote an increase the shrub and tree components of the undeveloped vegetative community and create additional cover and feed resources (which would be available above snowpack in severe winters) would be of great benefit to mule deer, though less so for elk. The critical parameter in this instance will be to limit vegetation removal in all phases to minimize disturbance at any point in time and to reclaim disturbed areas with a variety of grass and forb species as quickly as possible after mining activities cease. Bald Eagle: The absence of tall snags and mature tree species on the Property, its distance from the Roaring Fork River, existing urban development north of the site, and the plethora of superior habitat along the river corridor itself all significantly limit the suitability of this site for Bald eagles. Further, available habitat for key prey species on which eagles depend is also limited on the Property. The proposed mining operation is very unlikely to negatively affect bald eagles in any way. 7.0 Potential Mitigation Measures Since much of the open space and currently available habitat on the Property will be impacted during mining operations, those areas that remain undisturbed or which can be reclaimed will become increasingly important. The chief post -mining objective is to reclaim as much of the site as possible to agricultural production matching the current condition now found on the Property. There may also be an opportunity to develop multiple habitat parameters in the area, creating diversity and microclimates suitable for a broad variety of plant species that serve as both forage and security cover as well as travel corridors connecting fragmented habitats. Protection First and foremost will be protecting those areas during construction activities to minimize loss of vegetation and minimize soil erosion potential while adjacent areas are being developed. Soil disturbance during construction invites noxious weed invasion on surrounding areas and promotes establishment of a seed -source on the construction site. Therefore, weed monitoring and an active, multi -faceted control program should be implemented concurrent with construction activities. This would involve bi-weekly monitoring during the growing season throughout all phases of construction to rapidly identify weed species as they try to establish themselves, followed by immediate control 10 efforts utilizing mechanical and chemical control methods as appropriate. The Proponent has already developed an integrated weed control plan detailing weed identification and appropriate control measures for each species to which contractors must adhere during the construction process. One final protective measure could include pet restrictions, which should be enforced by disallowing employees to bring dogs onto the jobsite to prevent domestic dogs from running at -large and harassing wildlife. Enhancement Once mining operations on any phase have been completed, that area should be reclaimed as quickly as possible. For areas of the Property to be returned to agricultural production, the area should be contoured appropriately for maximum irrigation efficiency, irrigation capability restored to the site, soils returned to their proper locations (last out, first in) and all disturbed areas reseeded with a grass -legume hay mixture. Typical mixtures include orchardgrass, timothy, smooth brome and alfalfa. For those areas not suitable for ag-production, those sites should be re -seeded with an appropriate seed mixture containing species that are adapted to the soil and climatic conditions of that particular site, and which will establish quickly, compete well with potential noxious weeds and provide a preferred food source for native wildlife in the area. The fundamental idea is to formulate a seed mix with components that will establish quickly to retain exposed soils and prevent erosion, and other components that will remain established long-term, able to compete with potentially invasive species, and yet a third component that will offer a nutritious and palatable feed source for the targeted wildlife species. Specific seed mixes and planting rates could be easily developed for specific site conditions around the Property. However, for the purposes of this report, such a mix for the Carbondale region generally should include Intermediate, Western and Slender wheatgrasses, Sheep fescue, muttongrass, Needle -and -Thread -grass, Small bumet, a dryland-adapted alfalfa, a contingent of clover species and sainfoin. Planting rate should be about 20 lbs/PLS/acre. 11 8.0 Literature Cited Andrews, Robert and Righter, Robert. 1992. Colorado Birds. Denver Museum of Natural. History. Denver, CO. Cam, T.M., and G.

The existing weed infestations are shown on the Weed Management Plan Map. The primary infestation of kochia is on the large topsoil stockpile located on the east side of Mining Area 1 within the existing permit area. Additional small areas of weeds are located along the roads and on the southern slope of Mining Area 1. The existing weeds are anticipated to be removed within 2 years of treatment. Areas around the mining operation that have not been disturbed do not show signs of infestation. Weeds will be sprayed by a weed control contractor who is familiar with the area and species that will be encountered. The contractor will come to the site once a year in the early summer when the weeds are most vulnerable and treat each location with appropriate herbicide or as frequent as determined to be necessary by the county vegetation specialist. Once the existing. infestations have been controlled, an annual weed survey will be conducted to inspect for any new infestations either in the mining or reclamation areas. If new areas are identified, a specific plan will be produce to remove the weeds. The findings and proposed treatment will be submitted to the Garfield County Vegetation Specialist. As part of the DRMS bond release inspection a weed survey will be conducted and any infestations of noxious weeds will result in the bond not being released until the weeds are removed. Garfield County officials are welcome to attend any of these inspections to verify that the weed infestations are being addressed. Blue Pit - April 2010 Weed Management Plan
