The Blue Pit is separated fiom the Roaring Fork River Valley by an 8o'tall natural slope which remains after removing the gravel from an elevated alluvial terrace. Western Slope Aggregates, Inc. has a lease with the landowner of parcels 239)-254-c,o-265 and 2393-254-oo-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 roo feet thick. The groundwater level limits the mining of the deposit at approximately 9o feet deep in the expansion area and 6o 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 r98r under the DRMS Reclamation Permit # M-r98r-2o7. Western Slope Aggregates, Inc. has operated the site since i99r. The site expanded to an annual production rate of approximately 45o,ooo tons per year, in the early 2ooo's. The existing permit area is Bz.7o acres; approximately z5 acres is still able to be mined. This amendment application is to allow for an expansion area of approximately 6o acres, all of which will be used for additional gravel mining. The existing reserves will be exhausted in approximately 7 to 9 years and Western Slope Aggregates, Inc. wants to secure reserves further into the future. The expansion area is located directly adjacent to the existing operation and is shown the Index Map which is included in Exhibit B. The Garfield Counry Special Use Permit for this expansion was approved in zorz. This amendment as of zor4 is to revise the DRMS permit to coincide with the approved existing Garfield Special Use Permit. Blue Pit May 2014 i-1 Blue 1l-2 Permit Amendment Exhibit A - Legal Description and Location Map The Blue Pit is located approximately 2.5 miles east of Carbondale, CO. A legal description of the permit boundary is shown on Map C-r which is included in Appendix B. The total permir area is l.46.87 acres.

Map C-zB shows the pit fully mined out but not reclaimed. These contours on this map do not represent a true point of time since reclamation of slopes will occur on an ongoing basis. Blue Pit May 2014 c-1 Blue Pit 112 Permit Amendment ExhibitD-MiningPIan General Mining Plan The existing site consists of an active gravel mining operation with approximately 7 to g years of reserves remaining under the existing permit. Map C-r shows the current operation as of November zoo9. 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, Clifflord 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. Access to the mining area will be from an access road starting at Highway 82. The existing access to Highway 8z has an access permit from CDOT. Map C-r 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 shown as Mining Areas r and 3. This is the entire area of the rg8r approval, which includes all of the existing disturbance and additional area west of the Basin Ditch that has not yet been disturbed. The total area in the existing permit is 82.7o acres. The current approved plan allows zH:rV final slopes in all areas. As described in the Reclamation Plan, these slopes will be restored to a milder grade. Mining Area z is the proposed area of new mining under the expansion plan. The estimated volume of gravel to be produced after zoog from this mine is 9.r million cubic yards, which is approximately 13.6 million tons. The annual production is estimated to average 45o,ooo tons per year. The estimated time to mine 13.6 million tons of gravel at an approximate rate of 45o,ooo tons per year is about 30 years. Since mining has been occurring since zoo9, the 3o years would be estimated to end around 2o39. Demand plays a huge role in the exact time it will take to mine out the reserve. The gravel deposit is greater than roo feet deep in the area of the Blue Pit Expansion. The groundwater level ranges from approximately 6o feet below the surface in the current mining area and increases to 9o feet to rz5 feet in the expansion area. Since this operation will not intercept groundwater, the operation will stay at least z 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 Ioad the material to the crushing plant. As the mining face moves further fiom the existing crushing/screening plant location, a haul truck may be used to transpoft the material from the Blue Pit May 2014 D-1 Blue Pit 112 Permit Amendment mining face to the crushing/screening plant. The crushing/screening plant will produce stockpiles of different sized Aggregates, Inc. 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 r.5H:rV (670/o slope), except for the upper portion of the south slope in the amendment area of zor4, which will be mined at 3H:rV to allow for rapid re- vegetation to reduce the visual impacts to the Wooden Deer community which is located north of the permit area. This mining slope will recover the maximum amount of gravel as well as keeping a safe slope. Since the mining depth is 9o feet in some places and rz5 feet in other places, benches below the existing ground level will be created during mining to promote safe recovery of the material. The mine plan utilized three areas: Mining Area r is the bulk of the existing permit, prior to the zor4 Amendment. Area z is the expansion area and Area 3 is a small portion of the pre-existing permit area that may be mined at a later date due to visual impacts.

The life of the mine is estimated at 3o years after zoog and is based on an average annual production of 45o,ooo tons per year. The estimated raw gravel production is 9,o8z,z66 cubic yards or 13,623,399 tons over 30 years. This has been the average over the past life of the mine but sales are always dependent on demand. The East Topsoil Stockpile currently has ro5,B8r cubic yards of topsoil in it. The estimated additional topsoil to be removed from Area r is 32,38o cubic yards, which is calculated at r foot depth over the undisturbed area, which is zo.o7 acres. The estimated topsoil to be removed from Area z is ro6,335 cubic yards, which was calculated at r foot depth of the entire surface area. The estimated topsoil to be removed from Area 3 is 6,776 cubic yards, which was calculated at r foot depth of the entire surface area. The total estimated topsoil to be removed is r45,49o cubic yards. The total overall topsoil (to be excavated and existing topsoil stockpile) is estimated to be I5L,3ZL cubic yards. The estimated topsoil needed to put back is calculated at r foot over the entire surface area and is zz6,178 cubic yards. The difference is topsoil removed and topsoil to be placed is negligible and will be averaged out over the entire site. The topsoil volume was estimated using an average depth of r foot over the surface area. The overburden volume was estimated using an average depth of 4 feet over the surface area. Area r has already been partially mined (see Map C-r) and all volumes represent the future mining. Area r has over r million cubic yards of already excavated overburden and import material, which has * Area t has been already been only partially mined. The disturbed area is 44.5 acres as of 2011. The topsoil and overburden to be excavated is only for the unmined area. Blue Pit May 20L4 D-3 Volume Calculations Blue Pit 112 Permit Amendment been placed in the eastern portion of the permit area. There is also an existing topsoil stockpile located on the easternmost portion of the permit, on top of the overburden material. Table 3: Backfll Volumes Acres 64.57 6s.91 4.20 134.68 Backfill Needed On- Site 623,1,65 1,914,619 47,941, 2,585,724 Available On- Site Backfill On-Site 948,509 425,339 27,L04 L,4OO,g52 Backfilllmport Needed to On- Site (325,343) 1,489,279 20,937 L,!84,772 Topsoil Needed On- Site 109,013 1,10,073 7,092 226,L79 Topsoil Available On-Site 1,38,261 106,335 6,'176 25L,372 The existing overburden available for backfilling consists of the amount imported and backfilled in the east portion of Area r (8r8,99o cubic yards) and the amount available from future mining (58r,962 cubic yards) which is a total of approximately r.4 million cubic yards over the entire permit area). This is not sufficient to fully reclaim the site, but import material will account for the shortage. The total backfill volume required is z.5B million cubic yards needed on site minus the r.4 million cubic yards which is available on site, which is r.r8 million cubic yards. The average total volume of import material has been approximately 55,ooo cubic yards annually. Once mining in the expansion area commences, additional material can be accepted. Additional material was not able to be accepted due to space limitations. Also, the operator is currently charging to accept material. If more material is needed to reclaim the slopes, the fee can be waived. It is predicted that approximately 39,492 cubic yards would need to be imported annually to compensate for the backfill deficit of r.r8 million cubic yards. For this reason, it is essentially very reasonable to make the assumption that no import of backfill on site costwould be needed for the bond calculations, which are found in Exhibit L. The annual reports, which are not included in this application, will cite how much of import material is actually occurring on site each and every year. The plan is to continue moving west at the southern edge of the current 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 r. At some point when the mining area has expanded further to the west, a conveyor will be installed to convey the raw mined gravel to the crusher/screening plant, as shown on map C-zA. As mining moves to Mining Area z, the pit bottom will likely be lowered fiom an existing depth of approximately ZZ feet to 9o feet to rzo feet. This is entirely based on what is believed to be the level Blue Pit May 201.4 D-4 Overburden and Topsoil Backfill Volumes Blue Pit l-12 Permit Amendment of groundwater in the area, which is the limiting factor in the pit depth, since the operation cannot expose groundwater. Originally, it was proposed that the southern face of Mining Area z would be mined at a slope of r.5H:rV and the visible portion of this slope will be temporarily reclaimed as the pit is lowered. In this way, the homes to the north would primarily see a reclaimed slope on the south of the pit. The proposal in this application will mine the top 3o vertical feet of the south slope to a 3H:rV slope, thereby allowing rapid reclamation of this slope, since no backfilling will be needed. The slope will only require topsoiling for final reclamation. This will sacrifice reserves all the way to the bottom of the pit, but it will provide excellent visual protection to the homes to the north. The remainder of the slope to the bottom will be mined at r.5H:rV. 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 3H:rV slope, using overburden, processing fines and imported fill. The actual slope will be approximately3.rH:rV, since flat drainage benches will be installed on the slope to prevent later erosion. The plan basically allows for the reclamation of the southern slope of the pit to be reclaimed as it becomes visible, thus greatly minimizing the visual impacts. As the pit nears the western edge, the edge will be slightly visible until it is backfilled, but as the pictures in this report show, this impact is not significant. 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 or two weeks per year. Mining Area 3 is a small 4.2 acre area in the existing permit that may not be mined until later in the mine life. If this occurs, the mining of this area will cause temporary visual impacts to the homes to the north since this area is exposed. WSA commits to pushing the gravel material down to the pit bottom as fast as reasonably possible, and conducting the final reclamation of that small portion of the south slope as quickly as possible. Mine Facilities and Operations 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 are currently located north of the shop building. As mining progresses to the west, this faciliry 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-r. An office building exists near the mine entrance road into the permit area. It is a wood frame building on a concrete foundation. Blue Pit May 2014 D-5 Blue Pit l-12 Permit Amendment 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. A groundwater well (shown on Map C-r) will also be used. 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. lrrigation Ditch The Basin Ditch currently (see Map C-r) runs through the proposed expansion area. An agreement has been reached with the ditch company to leave a berm during mining to support the ditch. The berm will have 3H:rV slopes during mining. A cross-over road will be built to provide access across the berm. The berm and road are shown on Map C-zB. 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-r, C-zA and C-zB. This pile contains approximately ro4,ooo cubic yards. This material will be used to reclaim Mining Area r once final grade is achieved. Mining Area r requires 86,ooo cubic yards of topsoil for reclamation based on the restored thickness of rz inches. The excess will be used in other areas. Additional topsoil stockpiles will be located at the temporary wash plant location as shown on Maps C-zA and C-zB. 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 z feet to ro 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 couple weeks 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 z. 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:rV slopes. The amount of material needed to reclaim the slopes to 3H:rV is shown for each mining area on Map C- zA and Map C-zB. Import material will also be used in the reclamation process for backfilling slopes. This quantity and cost is addressed in the DRMS reclamation bond in Exhibit L.

The facilities area will house the mine office, the shop, parts storage and a truck scale. The employee and vendor parking area will also be located here. There will be no blasting as part of this operation. No refuse, acid or toxic producing material are expected to be encountered in this operation. If these material are encountered, topsoil will be placed over the area and mining will move to a different area. Any new fencing will be installed according to the Division of Parks and Wildlife's specifications. The operator commits to clearly marking the affected area boundary with stakes surveyed on site, once the permit is approved. It is planned that the material may be used to provide base material for construction projects in the area. One main road will be present in the mining area and will change locations in the pit as mining progresses. In pit roads are not delineated as they will move throughout mining. Access Road The site will continue to use the same haul route to Highway 82, which is a private road and is shown on Map C-zA and Map C-zB. The daily or hourly haul traffic is not increasing with the expansion of the reserves. 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 ro3 and CR ro4 to access Crystal Creek Road and is shown on Map C-2. 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 A. 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 Blue Pit May 2014 D-7 Blue Pit LLZ Permit Amendment 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 r and then mining as close as possible from Mining Area z. Schedule of Operations Mining and processing will continue to operate rz months per year. The hours of operation will be 7:oo a.m. to 5:oo p.m with administrative and maintenance functions occurring one hour prior and two hours after the hours of operation, Monday through Saturday. Garfield County lmpacts and Environmental lmpacts The aggregate production is estimated to be average 45o,ooo tons annually, although this is only approximate since past forecasts of economic conditions have been erratic. Impacts to Garfield County include: a) Truck traffic: The site will continue to use the same haul route to Highway 82, which is a private road and is shown on Map C-zA and C-zB. The daily or hourly haul traffic is not increasing with the expansion of the reserves. 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 ro3 and CR 1o4 to access Crystal Creek Road and is shown on Map C- zA and C-zB. The haul traffic from the current operation exits the site from a private road and intersects Highway Bz as shown on Map C-r. The haul traffic for the expanded operation will access the site in the same fashion as it does currently. The existing access to Highway Bz has an access permit from CDOT. 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 was conducted for CDOT to keep the existing access permit in the year 2or and CDOT determined that the existing permit is valid, CDOT will require improvements to Highway 8z access at a later date, which will primarily involve an extension of the acceleration/deceleration road lanes to the pit access road, which is located outside of the DRMS permit area. There is a small amount of truck traffrc that accesses the area north of the Blue Pit through CR ro3 and CR ro4. This access route is only used for product sales north of the pit on Crystal Creek Road and is a very small amount of the annual production. b) Noise: Western Slope Aggregate has operated the site since r99r 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 is part of the County Special Use process. c) 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 to date with items relative to dust emissions. Blue Pit May 2014 D-8 Blue Pit LL2 Permit Amendment d) Visual impact: As part of the county process, 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. e) The product from this mine will positively impact the local community by supplying construction material for the foreseeable growth of this part of Garfield County. It also has the advantage of supplying this area with construction material from the same area, thus limiting the amount of truck traffic and also greatly lessening truck traffic on the highway system, which in turn will lessen road repairs. Also, lessening truck traffic by providing construction Aggregates, Inc. near to the end use will also lessen the amount of greenhouse gases produced for many years to come. 0 The hydrological system will detain all runoff so that sediment will not leave the site and cloud any downstream waters. There will be sanitation facilities located in the mining area, therefore no leach fields or other means of sewage disposal within the mining area. g) The Blue Pit will be reclaimed to rangeland/wildlife habitat and irrigated pasture as shown on Map F-r. The operator will work closely with the Garfield County, NRCS, CDPW and the DRMS to ensure that the reclamation plan is the most appropriate for achieving the post-mining land use. lmport Fill, Recycled Concrete and Asphalt The pit may accept concrete and asphalt material that have been removed from existing sites in order that they can be recycled through the plants on site. Fill material may also be accepted into the mine site. Fill material will be spread out on the mined out pit floor and will be blended into the final landscape. Some material may also be re-sold as construction material. Any importation of structural fill material will occur in accordance with the requirements of Rule l.r.:(g). None of this material can be accepted by the Operator unless the attached form is filled out by the entity bringing the material to the site. The form provides an assurance that all material brought to the site is inert and has no toxic or acid forming material above acceptable limits. Blue Pit May 2014 D-9 Blue Pit 112 Permit Amendment Affidavit For lmport of Material into Blue Pit Date or Time Period of Import: Description of Import Material: Entity Providing Material to Pit (not the trucking Company): I hereby certify that the material described above and brought to the Blue Pit site is inert, which means it is free from any chemicals, toxic substances, acid forming material, or any other material which would violate the material waste disposal laws of the State of Colorado. Signature Written Name of Signer Signer's Position in Company Company Date: Blue Pit May 2014 D-10 Blue Pit 112 Permit Amendment Exhibit E - Reclamation Plan General Reclamation Plan As stated in the mining plan, the mining slope will be r.5H:rV to recover the material, with the exception of the upper portion of the south slope in mining area 2, which will have a maximum slope of 3H:rV. These slopes will be backfilled to the final reclamation slope of 3H:rV. A justification of reasons why this slope is appropriate at this site is given in Section 7-840 Gravel Extraction Regulations Exhibit I(. The reclamation slope in Mining Area r is currently z.oH:rV and will be changed to z.5H:rV with this Amendment of zor4. The material that will be used for this backfilling will be salvaged overburden, washed fines, and import fill. Backfill and import material will be used to reclaim the slopes in Mining Areas z and 3 from r.5H:rV to 3H:rV. The total permit area is 46.87 acres. The area to be minedisn3.59 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. The concrete plant will 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: Post Mining Land Uses Rangeland lrrigated Pasture Roads lndustrial Total 104.07 29.21 5.12 8.47 146.87 Overall, the pit slopes will be restored as rangeland and the pit floor in the western portion of Mining area 2 will be restored as irrigated pasture. The industrial site consists of the concrete plant and associated stockpiles and truck access. The concrete plant is not operated by Western Slope Aggregates 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. There are no costs associated with the landscaping of the concrete plant area. 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 of 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 Blue Pit May 201.4 E-1 Blue Pit LLZ Permit Amendment the property. A ramp road to the irrigated pasture will also be installed to allow farm access to the western bottom area. The farm road will be maintained by Western Slope Aggregate until the DRMS bond is released. lrrigation Ditch The Basin Ditch currently (see Map C-r) runs through the proposed expansion area. An agreement has been reached with the ditch company to leave a berm during mining to support the ditch. The berm will have 3H:rV slopes after mining. A cross-over road will be built to provide access across the berm and left after reclamation. The berm and road are shown on Map F. Topsoil Placement The East Topsoil Stockpile currently has ro5,88r cubic yards of topsoil in it. The estimated additional topsoil to be removed from Area r is 32,38o cubic yards, which is calculated at r foot depth over the undisturbed area, which is zo.o7 acres. The estimated topsoil to be removed from Area z is ro6,335 cubic yards, which was calculated at r foot depth of the entire surface area. The estimated topsoil to be removed from Area 3 is 6,776 cubic yards, which was calculated at r foot depth of the entire surface area. The total estimated topsoil to be removed is t45,49o cubic yards. The total overall topsoil (to be excavated and existing topsoil stockpile) is estimated to be z5t,37l cubic yards. The estimated topsoil needed to put back is calculated at r foot over the entire surface area and is zz6,178 cubic yards. The difference is topsoil removed and topsoil to be placed is negligible and will be averaged out over the entire site. Additional topsoil stockpiles will be located at the temporary wash plant location as shown on Maps C-zA and B. 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 z feet to ro 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 z. 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:rV slopes. The amount of material needed to reclaim the slopes to 3H:rV is shown for each mining area on Map C- z. Currently Mining Area r has an excess 8z9,ooo 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 quantiry and cost is addressed in the DRMS reclamation bond. Blue Pit May 2014 E-2 BIue Pit 1l-2 Permit Amendment Topsoil has been salvaged from the existing operation and is stockpiled on the eastern portion of the existing permit area (See Map C-z). 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 rz 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. Haul Roads and Access The haul roads that will remain after reclamation are shown on Map F. 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. 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 C-3 for further details on the reclamation sequencing which includes the temporary and final reclamation activities.

This is not sufficient to fully reclaim the site, but import material will account for the shortage. The total backfill volume required is 2.58 million cubic yards, which is less than the r.4 million cubic yards available which is r.r8 million cubic yards. The average total volume of import material has been approximately 55,ooo cubic yards annually. Once mining in the expansion area commences, additional material can be accepted. Additional material was not able to be accepted due to space limitations. Also, the operator is currently charging to accept material. If more material is needed to reclaim the slopes, the fee can be waived. It is predicted that approximately 39,492 cubic yards would need to be imported annually to compensate for the backfill deficit of r.rB Blue Pit May 2074 E-3 Overburden and Topsoil Backfill Volumes Blue Pit 112 Permit Amendment million cubic yards. The annual reports will document the amount of import material imported on site each year. Revegetation Plan Trees will be installed along the northern border of Mining Area z prior to any new mining activity. Prior to any mining in the expansion area, WSA proposes to plant at least 65 trees of at least ro feet height along the northern boundary of the expansion area. This will help shield all activities from the view of the homes located north of the pit. WSA will irrigate these trees and maintain them over the life of the operation. It is planned to plant a mix of evergreen and deciduous trees. 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. If the 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 irrigated pasture will be landscaped by placing topsoil back on the pit floor and seeding the land with the irrigated pasture mix. The existing side roll irrigation system from the pre mined irrigated pasture will be reused on the post mine irrigated pasture. All equipment will be removed from the irrigated pasture area. See the Map F for the location of the irrigated pasture. No trees or shrubs will be planted in this area. The irrigated seed mix will be drill seeded into the tilled soil with z,ooo lbs of straw per acre. The cost of topsoil placement and seeding is anticipated to be $3,ooo Per acre and z9.zr ircr€s = $88,ooo. Western Slope Aggregates operates the current irrigated fields for the landowner and will likely continue this practice until the DRMS bond is released. There are flat and sloped areas that will be landscaped to rangeland. These areas are shown on the Map F. The rangeland seed mix will be drill seeded into the tilled soil with z,ooo lbs of straw / acre. The rangeland seed mix has Four Wing Saltbrush and Rubber Rabbit Brush to provide the shrub requirement in the rangeland landscape. 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 fields being used for irrigated pasture they were a grass/shrub mix with minimal trees. 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 on the northeast corner is captured by the Basin Ditch and the Spring Ditch and will continue to do so after reclamation. To the south, the highway ditch will divert most drainage to the west and out of the pit. The northwest rim of the pit will have a constructed z'berm Blue Pit May 2014 E-5 Blue Pit 112 Permit Amendment to divert drainage away from the pit. The west side of the pit drains away from the pit. See Figure z for a map of the general drainage of the reclaimed site. Within the pit all runoff will be controlled. All disturbances are graded to the pit floor which is sufficient to hold a 1oo 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:rV side slopes will have 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. See Exhibit G for more details on the design of the ditches and grouted channels. The Basin Ditch currently (see Map C-r) runs through the proposed expansion area. An agreement has been reached with the ditch company to leave a berm during and after mining to support the ditch. The berm relocation is shown on Map F. Blue Pit May 201.4 E-6 Blue Pit 112 Permit Amendment L€gerd Flow Dlrcctlcn nrryord IffiBsfifiryUt,'I *m Figure 2: Post Mining Drainage Map The Rangeland slopes will also receive stormwater runoff protection. This protection consists 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 and prevent gullying on long lengths of slope by interrupting these slopes with the ditches on the catchment benches. 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. Additionally as the mining face progresses, the area that will become visible must have temporary vegetative cover. The lower bench of the reclaimed area (34.63 acres) will be restored to irrigated pasture. The success criteria of this area is usually generally based on goo/o of the production of alfalfaigrass from the pre-mine fields. Blue Pit May 2014 E-7 Blue Pit 1,L2 Permit Amendment The revegetation will be deemed adequate for the when erosion is controlled and is considered satisfactory according to Division standards. Monitoring Reclamation Success Monitoring the reclamation on an ongoing basis will ensure its success. The operator plans to use the local NRCS office to determine the capacity of the reclaimed land to control erosion. If minor changes or modifications are needed to the seeding and reclamation plan, revision plans will be submitted to the Division. It is hoped that the Division will provide assistance in evaluating the success of the ongoing reclamation process. Information on all areas disturbed and reclaimed as well as any other important items regarding the reclamation will be submitted in the annual reports to the Division. Garfield County and Division of Parks and Wildlife will also be consulted on the progress of the reclamation. Blue Pit May 2014 E-8 Blue Pit 112 Permit Amendment Weed Control Measures will be employed for the control of any noxious weed species. Control measures will also be used if the growth of weed species on the reclaimed area threatens further spread of the weeds to nearby areas. A Weed Control Plan will be utilized as follows: 1) Each April, a weed survey will be taken of the permit area. If any patches or plants have been identified, they wilt be sprayed by backpack sprayer or 4-wheeler using chemicals approvedfor use by the weed control staffof Garfield County. After reclamation, weed surveys and spraying will continue until the perennial cover and production of the site have met DRMS requirements and bond release has been obtained. The Division and Garfield County weed control staff will be consulted regarding any weed infestation areas and any control measures prior to their initiation. The plan does not contemplate total weed removal on the property. Past experience has shown that some initial weed cover in the first year following the re-topsoiling is beneficial to the reclamation effort in rangeland site 2) 3) Blue Pit May 2014 E-9 Blue Pit 1L2 Permit Amendment Exhibit F - Reclamation Plan Map Exhibit Map F shows the final contours of the reclaimed area as well as the final land uses. Blue Pit May 2014 F-1, r Blue Pit 112 Permit Amendment Exhibit G - Water Information Sunface Water General Discussion The Blue Pit is separated from the Roaring Fork River Valley by an Bo' tall natural slope which remains after removing the gravel from an elevated alluvial terrace. The pre-mine site was used for irrigated pasture and the western portion of the site still serves this use. This irrigation water enters the site from the south in the Basin Ditch. Hydrology and Sediment Control for during Mining Almost the entire site drains to the bottom of the pit with the exception of the East Topsoil Stockpile. This Stockpile will have a ditch and berm to prevent runoff from leaving the site, therefore, no discharge permit is needed for the site. The pit is approximately 6o feet deep and will become deeper in the western portion of the mine, therefore, it is more than adequate to handle an event larger than the 1oo year event with no discharge. No water from south of the permit area enters the site since it flows south to Highway Bz. No water from the east enters the site due to a berm placed around the eastern portion of the site adjacent to the east Topsoil Stoclgile. No water from the North enters the site, since it is intercepted by the Spring Ditch in the eastern part of the permit and the berm with trees for the north portion of Mining Area z. This berm will be z.o feet high and will have 3:r sidelsopes and will be vegetated upon construction. The berm is shown on Maps C-zB and Map F. No disturbance will take place south of this area until the berm is installed. No water can encer the site from the west since this area drains to the west and is now part of the Cerise Pit for United Companies. One of the challenges thatWestern SlopeAggregates, Inc. 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 \ /ater to users downstream. This will be accomplished by creating an irrigation berm with a 3H:rV grade with an open ditch to move the water, as shown on Maps C-zA and C-zB. This will be done in the winter when the ditch is non- functional. All plans and details have been evaluated and approved with the Ditch Company prior to making the changes. AII documentation pertaining to this are found located in Appendix C. The Spring Ditch also enters the permit area in the southeast corner and then enters a holding pond from which the water goes in a 4" HDPE pipe along the eastern edge of the permit area as shown on Map C-r and C-zB. Once the northeast corner of the permit area is reached, the water re-enters an open ditch which is north of the permit area and moves water to the west. Hydrology for after Mining (long term) Blue Pit May 2014 G-1 Blue Pit L!2 Permit Amendment Sitr: Map and Grading I'lan The erosion control measures to be installed are shown on Map F which is located in Appendix B. The final grading of the site is shown on Map F. The final slopes of the site will be 3H:rV for Mining Areas z and 3. Mining Area r of the existing operation will be reclaimed to minimum of z.5H:rV. As described above, a small z.o'berm will be installed on the northwest and east side the mining area assure that no runoff from the irrigated pasture enters the pit as shown on Map C-zB and Map F. Drainagc Structurcs There are no drainage features that will enter the Blue Pit reclaimed area. The berm on the north portion of Mining Area z will be left in place to reduce runoff to the reclaimed slope. Surface water runoff will also be intercepted by the Spring Ditch in the northeast portion of the permit area. A z.o feet high berm will also be left in place on the eastern edge of the permit area to prevent runoff from entering the pit from this direction. The Basin Ditch will have an open ditch to move the water, as shown on Maps C-zA and B. 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 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. Cons(ruction Sclredule 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 ro-3o years. The temporary revegetation of the topsoil pile will be within 6 months of the topsoil being placed. No immediate backfilling of slopes in area r can take place or occur since the area is used to the facilities area. Pcrmancnt Stabilization Permanent stabilization of the slope areas will be achieved through seeding with the rangeland slopes. Also the stormwater catchment benches will be installed with a concrete lined ditch for the water to get to the pit floor at key locations. See design details on following pages. See Map F. Permanent stabilization of the irrigation areas will be through seeding with the irrigated pasture seed mix and installation of irrigation system. 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, the z foot berm left in place 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 loo 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:rV side slopes will have 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 M"p). Blue Pit May 2Ot4 G-2 Blue Pit 112 Permit Amendment The concrete plant is not operated by Western Slope Aggregates and it is anticipated that upon mining and reclamation being completed the concrete plant will remain in place. No revegetation 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. The concrete plant will have some stockpiles associated with it. The entire faciliry will be within the reclaimed pit. The pit will have sufficient capacity to prevent stormwatet discharges from ever occurring. Therefore, the concrete plant facility does not require additional drainage control. 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 3o vertical feet. The breaks in the slope are going to be the Stormwater Catchment Benches which will collect the water and transport it to the Grouted Channels, which bring the water to the bottom of the site. The Stormwater Catchment Bench design is shown below.

Maintenance of Best Management Practices The BMP's for this operation are the contemporaneous reclamation of the slopes, the installation of bench catchment benches ditches and the installation of grouted channels to bring the water to the bottom of the pit. Western Slope Aggregates is responsible for the maintenance of these structures. 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 there will be no runoff for the roo year event. 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.

Parker, CO 80138 RE: Need for a Stormwater permit Dear Mr. I-cwicki: This is in response to your letter of December L3,2W2, regarding the need for a stormwater pe rmit and Stormwater Management Plan (SWMp) for a gravel mining operition. The_ stormwater regulations apply to mines only if rulroff contacG overburden, raw material, intermediate or fiaished product, or waste products, and has a reasonablc potentiat of reaching state waters. If all runoff from the mine site an any of the disturbed areas is contained on site, witht discharge off-site expe_cted, a stormwater permit is not required. The Clean Water Act does not establish a thieshold (e.g., a 100-year storm event); the potential for any discharge is determined by the site owner/operator. If theowner/operator determines that no permit is needed and so does not apply for one, keep in mind that any change in this situation would require application for a stormwater p.*it at least 30 days prior to a1ry discharge taking place. If you have any questions, please give me a call at (303) 692-3596. Sincerely, Kathryn Dolan Stormwal.er Program Coordinator Permits Unit WATER QUALITY CONTROL DIVISION Blue Pit May 2014 G-7 Blue Pit l-12 Permit Amendment Groundwater The groundwater level limits the mining of the deposit at approximately 9o-rzo feet deep in the expansion area and 6o-7T feet in the 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. It is believed that the groundwater level is deeper in the western portion of the pit due to seepage from the existing Basin Ditch which makes the water level higher in the eastern portion of the permit area. There are no visible seeps or springs, and groundwater is not expected to be encountered during mining. While no groundwater is anticipated to be exposed by excavation, if it is exposed, excavation will cease at an elevation of z feet above the groundwater level. Water for this site is supplied from the Basin Ditch, and a well on site. All of these structures are shown on Map C-r. The mining operation has an approved augmentation plan for the use of the water from the Basin Ditch which is located in Appendix A. The water is used for dust suppression, material crushing, screening washing and concrete production. lrrigation Water Irrigation has historically occurred on the vast majority of the permit area. The irrigation water comes from the Basin and Spring Ditches, where the property owner has existing irrigation rights. See Appendix A. Once the site is fully reclaimed, these rights will be used to irrigate the bottom area, as shown on Map F. Water Consumption for the Operation The Pit is on an elevated terrace and there is no groundwater on the terrace. This is known from existing operations on the terrace further north of this site and also the lack of springs emanating from the base of the gravel anynrhere on the site. There is very little moisture in the gravel that will evaporate when the material is mined. 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. r) 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 r.35 Acre-feet Dust Control r.54 Acre-feet Crusher / Screen z.o9 Acre-feet Concrete Truck Washout 2.38 Acre-feet Blue Pit May 201.4 G-8 Blue Pit L12 Permit Amendment The source of the water to be used by the Blue Pit Expansion is the Basin and Spring Ditch. Also there are z wells on site which supply water to the concrete plant and the shop. These items are shown on Map C-r. The water supplied from the Basin and Spring Ditch as well as the wells on site are not used for drinking water. Potable water is provided by bottled water. 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 wells. A majoriry of the water demands are during irrigation season. 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. A majority of the water consumption occurs during irrigation season. Washed material is stockpiled through the winter to reduce winter water needs. The determination was made in the decree of Appendix J that the mine will utilize 7.4 acre-feet of consumptive use which was made available from the r.o cfs that is the historic water right for the property. This amount of water (7.4 acre-feet) at the mine has been sufficient for all consumptive uses and since production is not changing for the zor4 amendment, the existing water rights are sufficient. z) 4) 6) Blue Pit May 20L4 G-9 5) Blue Pit 112 Permit Amendment Exhibit H - Wildlife Information Almost the entire site was previously an irrigated pasture on a terrace above the roaring Fork River. Much of the western portion of the site which has not yet been disturbed, is still used as irrigated pasture. The following is an excerpt from the "Wildlife and Habitat Assessment - Western Slope Aggregate Parcel" by Environmental Solutions, Inc. (April zoog). "Records searches, interviews with CDOW personnel and the sire visirs revealed a number of wildlife species known to use tl^te Property. Despite the generally monocultural nqture of most of the vegetation in the qree, e reasonably diverse array of species frequent the Property, including elk, ntule deer, coyote, cottontail rabbit, and other small mqmmals. Avariety of bird species also utilize the area, at Ieast seoson ally, including a wide range of songbirds and raptor species. However, despite the number of species known to L.se the area, most are notably habitat generalists. There are no special habitat paranleters nor specialized species seeking specific habitatfunctions on the Property. Time and space constraints dictate that this analysis will focus on those wildlife species that are of signifrcant ecological, economic, regulatoty or political importance. Other species or ecological elements assuredly occur on the Property, but are omitted in rhis discussion due to one or more of the following: t) they will not be significantly impacted by the proposed action; z) they are not specifcally regulated by local, state or federal law or code; ) their life cycle and/or habitat use criterion do not make them reasonable indicators of probable effects to other wildlife species. Several Federal q.nd State' listed Threqtened 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 reasonlor dismiss al from further review are shown in Table z. Three species were selected for analysis because of their regulatory status, sensitivity to human activities, known use of the study orea, limited habitat resoltrces in the region and/or their ability to serve as indicators of probable effects to a variety of other wildlife species. Each species is discus sed, 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. Table z: Threatened, Endangered and Sensitive species precluded from detailed anolysis on the Western Slope Aggregate Parcel.

Further, both these species serve as "umbrella species," which meqns that if habitat requiremenfs ro meet the needs of these species qre present, thenwe Blue Pit May 201-4 H-2 Common Nome Scientific Nome Status Reason for Dismissol Blue Pit 112 Permit Amendment can safely cssume that a great many other species will be adequately supported in the area as well (Caro & O'Doherty ryg9, Lambeck ryg7, Roberge & Angelstam zoo4). Mule deer are known to utilize the site throughout the year. The Property is not considered to be a production area but is shown os normal summer rangefor the species. There are no migration corridors mapped on the site by CDOW. However, the Property is listed as a Winter Concentration Area, which oreas are defined as locations that harbor zoo%o higher densities of animals 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 defned as the area on which 9o% of the animqls may occur when annual snowpack is qt its maximum andlor when temperatures are at their lowest during the worst two winters out often. CDOW considers suc/i sires 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 availablefor deer during thewinter 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 qttractive for deer due to the flat tetain and distance from security cover. That said, deer do make some use of the hayfelds throughout the year so long os sno)l/ cover remqins shallow enough and uncrusted to permit them to forage. Generally, however, deer make notably /ess 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 seosons, and throughout the winter months as long os snou/ cover retnains 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 ofwinter range at all by CDOW.Ihis is surprising in that CDOW typically maps general winter ronge 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 unsuitablefor 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 ofopen Blue Pit May 2074 H-3 Blue Pit LL2 Permit Amendment forage and lack of security cover may be the reoson CDOW does not include rhis sire in its winter range mqpping. If subdivision development becomes denser 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 Threqtened species qnd because they select relatively quiet, undisturbed riparian sitesfor nesting, ond they require healthy aquatic ecosystems to provide adequote food resources. As such, they are an excellent indicator of the relative heqlth and viability of many other species in the area. There are no Bald eogle nests known to occur on the Property, ond the nearest active nesf site is over jo sir-miles away from the Property on the Colorado River itself. There are two known winter roosf sifes 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 Jlying in the vicinity during winter months, which would be expected due to the relative proximity of the Roaring Fork corridor and much of the valley being mapped as winter foraging habitat for the species. However, there are no criticql hqbitctt parameters for this species on the Property. The scarcity of mature cottonwoods or other toll tree species suitable for eagle nest sites, the abundance of road.s ond human activity already taking place in the orea and the distance from the Roaring Fork River makes this o very unattractive location for nesting or roosting. The plethora of mature cottonwoods present along many miles of the Rooring Fork river corridor provide numerous adequate perches for hunting or roosting as well os nesr sites along the river, which supplies far more productive hobitat for this species than anything found on the Property. Potentiol Effects of the Proposed Project The proposed project will result in significant surface disturbance of the relatively level hayfields on the Property. Grqvel extraction requires removal and stockpiling of topsoil and overburden subsoils, and the mining itself removes aggregate Aggregate,t Inc. permanently, changing the contours of the site in perpetuity. The direct physical effects to existing habitot are clear: open space, forage production and overall habitat availability will be significantly decreosed on the Property during mining operations. Indirect effects include dust and particulate emissrons, noise pollution ctnd potential trffic col/isions with wildlife. However, the effect of this hqbitat impact moy be limited to the temporal fficts of the mining activity, which is alreody occurring. Reclqmation plans include restoring the Property to agricultural production qt 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 qnd elk, though less so for bald eagles, during the productive lifespan of the pit. It should be noted, however, thqt both the direct and indirect impacts discussed above will occur in phases on a 98-acre parcel of marginal, open habitaf. Such an impact will clearly be minor when viewed in a regional habitat context. Blue Pit May 2014 H-4 Blue Pit LtZ Permit Amendment These cumulative changes wilt likely deuease suitability of remaining habitat for most species, though prolific, adaptable species such cs cottontail rabbits, red fox and a number of songbird species may persist or even increase in abundance. Potential effects and opportuniries posed by the proiect for the key species identifed in Section 5 are discussed below. Mule Deer qnd EIk: Since both mule deer and elk make primary use of the Property during winter months, and sincewinter 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 fficts to both species. However, since the existing habitat consisfs of ircigated 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 vegetotive community r.nd 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 instonce will be to limit vegetation removal in all phases to minimize disturbance at any point in time and to reclaim disturbed areqs with a variety of grass and forb species as quickly as possible after mining activities ceose. BaId 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 signifcantly 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 isvery unlikely to negatively ffict bald eagles in any way. Pote ntiql Mitig ation M easur es 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 sire as possible to agricultural production matching the current condition now found on the Property. There may also be an opportunity to devetop multiple habitat psrameters 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 coruidors 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 qre being developed. Soil disturbance during construcfion invites noxious Blue Pit May 2014 H-5 BIue Pit LL2 Permit Amendment weed invasion on sutounding areqs and promotes estqblishment of a seed-source on the construction site. Therefore, weed monitoring and an active, multi-faceted control program should be implemented concunent with consfrucfion activities. This would involve bi-weekly monitoring during the growing secson throughout all phases of constructton to rapidly identify weed species as they try to establish themselves, followed by immediate control ffirts utilizing mechanical ond 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 meosure 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 harqssing wildlife. Enhancement Once mining operatiotls on any phase have been contpleted, tlnt 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, ircigation capability restored to the sitg soils returned to their praper /ocafions (last out, first in) qnd all disturbed oreas reseeded with a grass- legume hay mixture. Typical mixtures include orchard grass, timothy, smooth brome and alfalfa. For those areas not suitablefor ag-production, thosesites shou/d be re-seededwith on 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 noxfous weeds and provide a prefened food source for native wildlife in the area. The fundamental ideq is to formulate a seed mix with components that will establish quickly to retain exposed soils and prevent erosion, and other components that will rernain 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 lntermediate, Western and Slender wheat grasses, Sheep fescue, muttongrass, Needle-and-Threqd-grass, Small bumet, a dry land- adapted alfalfa, a contingent of clover species and sainfoin. Planting rate should be about zo lbslPLSlacre." Mitigation and Enhancement Trees will be installed along the northern border of Mining Area z prior to any new mining activity. Prior to any mining in the expansion area, WSA proposes to plant at least 65 trees of at least ro feet Blue Pit May 2014 H-6 Blue Pit 112 Permit Amendment height along the northern boundary of the expansion area. This will provide habitat for wildlife. 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. If the 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 disturbances to wildlife. The temporary seed mix will be made up of Annual Ryegrass, Triticale, Oats, Crested Wheatgrass, Smooth Brome, and Slender Wheatgrass. The irrigated pasture seed mix will be made up of alfalfa, orchard grass and meadow brome. The rangeland seed mix will be made up of Western Wheatgrass, Thickspike Wheatgrass, Slender Wheatgrass, Green Needlegrass, Indian Ricegrass, Mountain Brome, Four Wing Saltbush, and Rubber Rabbit Brush. These seed mixed incorporate the much of the recommendations by Environmental Solutions as shown above. Also measures will be employed for the control of any noxious weed species. Control measures will also be used if the growth of weed species on the reclaimed area threatens further spread of the weeds to nearby areas. Significant Wildlife Resources on the Affected Lands There are not significant wildlife resources on the affected lands. Mule deer and elk may have used the site prior to disturbance. Eagles could use the large the trees adjacent to the river, but that area is not affected by the mining. Significant Non-Game Resources on the Affected Lands There are no significant non-game resources on the affected lands. Seasonal Use of Affected Lands The affected lands could potentially be used seasonally by mule deer and elk. Presence and Estimated Population of Threatened or Endangered Species There is no presence or estimated population of threatened or endangered species. Fish Resources There are no fish resources within the permit area. General Effects of the Operation on the Existing Wildlife There are not expected to be any negative effects on the existing wildlife. The rangeland slopes and irrigated pasture at the bottom area will provide some unique areas for deer, elk and small mammals to utilize after reclamation. Blue Pit May 2014 H-7 Blue Pit 112 Permit Amendment Exhibit I - Soils Information The soil survey performed by the NRCS covers the permit area. The soil mapping is shown on the Exhibit B Map. The associated soil lype descriptions are listed below. Soils encountered on the site were comprised entirely of Empedrado loams as mapped by the NRCS. These soils ranged from z-60/o slope and are deep, well-drained soils with moderate permeabiliry and high water capacity. Surface runoff is medium and erosion hazard is slight on the Empedrado soils. These soils are well-suited for bay production, small-grain crops and pasture. Records indicate this soil type can annually yield 5 tons bay/acre or 9o bushels of barley/acre under proPer management. lt has few limitations, but performs best if a crop residue is left covering the field over the winter and with adequate fertilizer added annually. An existing topsoil stockpile is located at the eastern edge of the current disturbance area, as shown on Maps C-r, C-zA and C-zB. This pile contains approximately ro4,ooo cubic yards and is located within Area r. This material will be used to reclaim Mining Area r once final grade is achieved. The excess topsoil from Area r will be used for Area z, which is deficient in topsoil. Table 6:'lopsoil Vcslumes 64.57 65.91 4.20 134.68 109,013 'l.to,o73 7,A92 226,L78 L38,261 106,335 6,776 25L,372 The existing disturbance of Mining Area r requires 1o9,o13 cubic yards of topsoil for reclamation based on the restored thickness of rz inches. The volumes for all areas are shown in Table 6. The excess will be used in other areas. Additional topsoil stockpiles will be located in the pit as it is expanded. Additional area to the north of the existing excavation may 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 z feet to ro 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 topsoil/overburden 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 as mining transitions to Mining Area z. 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. The topsoil will be removed with a loader or excavator at the existing ground level. The material will be loaded into trucks and hauled to the topsoil stockpile or areas ready for reclamation. The overburden will also be removed with a loader or excavator at near the existing ground level. The Blue Pit May 2014 t-L Area Acres Topsoil Needed TopsoilAvailable L 2 3 Total Blue Pit 112 Permit Amendment material will be loaded into trucks and will be deposited in areas where backfill is needed. The topsoil stockpile will be seeded within a year after it is created with the same seed mix shown in the reclamation plan.

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. The Property consists almost entirely of irrigated hay, with the most prevalent species consisting of Smooth brome (Bromus inermis), Orchardgrass (Dactylis glomeratc), I(entucky bluegrass (Poa pratensis) and Dandelion (Taraxicum o.fficinale). There are also small contingents of alfalfa (Medicago sativa), Sweetclover (Melilotus o.fficinalis), Common plantain (Plantago major) and Western salsify (Tragopogon dubius) amid the hayfields. Some fields 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 corner 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 (Achtllea millefulium ), along with more weedy species such as Ragweed (Ambrosia psilostachya), Tumblemustard (Sisymbrium altissimum), Curlycup gumweed (Grindelia squarrosa), I(ochia (Kochia scoparia), Curled dock (Rum ex 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 viscidiflorus), 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 (Hilariajamesir) and various penstemons (Penstemon spp.).There are no riparian areas nor wetlands found anywhere on the Property, though there is a small stand of cottonwoods about half a mile west of the Property where it is reported that eagle's sometimes perch during the winter months. A list of plant species found on the properry is provided in Table r.

The east Topsoil Stockpile is still in place and the excess fill in the eastern portion of Mining Area r has not yet been moved. Structures to be Removed The haul roads that will remain after reclamation are shown on Map F. 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. All structures (except for the concrete plant) will be removed. These structures include the to be removed mine office on a concrete foundation, truck scale, fuel tank containment and all portable equipment in the pit and scale. The conveyors, crushers and screening plants will be portable only. Backfilling Backfilling will consist of z separate tasks: t- The eastern portion of Mining Area r will require backfilling on the north, east and south slopes. This material will be obtained from the excess fill previously placed on the eastern portion of Mining Area r. The volume required is based on backfilling approximately 3,3oo feet of slope from approximately zH:rV to z.5H:rV over a distance of 3,3oo feet. Based on the surface models of Map C-zA and Map F, this is a volume of 359,647 cubic yards. The material will be obtained by pushing down the existing fill slope with a Cat D-B dozer and then a loader will load 25 ton trucks to haul the material an average distance of yS feet to the toe of the slope where an additional D-B dozer will push up the slope to complete the backfill. The cost of this work is expected to be $3.o5 per cubic yard. 2- As described above, 5oo feet of pit length in Mining area 2 will require backfilling from r.5H:rV to 3.oH:rV. The backfill for this task will be obtained from the most recent overburden cut. Western Slope Aggregates, Inc. commits to no more than 5oo feet of this slope requiring backfill at any one time. The volume required to backfill this area is ry7,867 cubic yards, based on a depth of 9o feet. The cost to place this material is based on moving all the material from the eastern portion of Mining Area r. Since there is minimal distance for the trucks to move the material, the cost of this work is $2.25 per cubic yard. Some excess fill may remain in place in the eastern portion of Mining Area r as long as this fill has a slope of no steeper than 2.5:rY. Therefore the total backfill required is 497,5t4cubic yards. Since this material will be pushed up from the pit bottom, the cost per cubic yard is $2.25. Also at this time, there will be the largest amount of pit floor, plant area, internal roads and in-slopes to reclaim to irrigated fields/rangeland. These areas are determined below. Blue Pit May 20L4 L-1 Blue Pit LtZ Permit Amendment Basin Ditch Construction The permanent installation of the Basin Ditch wilt be minimal to its final configuration setup and will not require backfilling at all for reclamation purposes. There is no cost for this item' Catchment Benches, Ditches, Concrete Grouted Channels and Energy Dissipation Rock As shown on Map F, many catchment benches with ditches must be constructed on the final3H:rV slope to prevent erosion. These ditches will lead to grouted channels which will deliver the runoff water to the bottom of the reclaimed pit areas. As described in the Reclamation Plan, large energy dissipation rock will be needed at the toe of each grouted channel. This rock will be available on site and collected during mining for later use in this reclamation. The estimated cost of installation of the catch benches and ditches is $r per foot. The estimated cost of installation of the grouted channels is $6 per foot. The length of catch bench/ditch needed would b" 35,)99 feet. The length of grouted channel needed would be 3,4t6.9t feet. Therefore the cost is $35,)99 and $zo,5or.

Garfield County Special Use Permit (completed for the proposed DRMS Amendment and approved in zotz) . An Augmentation Plan from the Division of Water Resources is nof needed for the operation since rhis is not a wet pit that will leave a gravel pit lake.

(approved) o Construction Permit (Air Pollution Control Division) - Permit number o7GAo559 for cone crusher, Permit number oTGAojjo for screening plant, Permit number o7GAo559 for crusher, o8GAo9& for concrete facility (approved) . A Spill Prevention Control and Countermeqsure (SPCC) Plan is needed for the mining operation since the site tank storage exceeds ryzo gallons. Other tanks that will be located on sife will be associated with the individual processing plants. Fuel will be brought to the site with a mobile fueling truck. No spilled material will be allowed to leave the site and all tanks will have secondary containment. In addition, the portable plants that will be on site from time to time each have their own separate SPCC Plans. (in place) o Water discharge permit is not needed since the site will not discharge water at any time during the entire life of the mine. o An Army Corps of Engineer 4o4 permit will be nof necessary because no wetlands or waters of the U.S. will be disturbed.

Please see enclosed sign certification. Blue Pit May 2014 T-1 Blue Pit 112 Permit Amendment NOTICE This site is the location of a proposed construction Aggregates, Inc. operation. Western Slope Aggregates, Inc., whose address and phone number is 14682 Colorado 82, Carbondale CO 81623, (970) 963-155 l, has applied for a Reclamation Permit with the Colorado Mined Land Reclamation Board. Anyone wishing to comment on the application may view the application at the Garfield County Clerk and Recorder's Office, 109 8tl' Street STE 200, Glenwood Springs CO 81601, and should send comments prior to the end of the public comment period to the Division of Reclamation, Mining, and Safety, I 3 13 Sherman St, Room 2 1 5, Denver, Colorado 80203. Certification: I,hereby certifu that I posted two signs containing the above notice for the proposed permit area known as the Blue Pit , on: Date Posted The signs were posted at the start of the access road on Highway Bz and the much less used intersection of Blue Road (ro4) and Road ro3, which is northwest of the permit area. SIGNATURE DATE Blue Pit May 20L4 r-2 Blue Pit 112 Permit Amendment Exhibit U - Geotechnical Stability 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 fiom 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 r.5H:rV and reclaimed to a 3H:rV 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 The reclamation plan calls for z benches of ro feet width in a slope height of 9o feet, therefore, the overall slope will be reduced from 3:r to 3.1:1. These slopes will also be used to collect runoff from the slope itself and reduce erosion. The 3:r slope will be backfilled, topsoiled and reclaimed to dry rangeland, as desired by the landowner and required by the DRMS. 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- foz.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 zo degrees or z.7H:rV. This angle is far milder than normal failure angles in material that gets strength from internal angle of friction. Figure a-5oz.C(6)8, fiom Huang, shows typical internal angles of friction for various Aggregates, Inc.. 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.

In addition, the exposed r.5H:rV 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:rV. 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 z8 year of experience in mine slope safety analysis in Colorado, certiSr 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 stabiliry of any structures outside of the permit area" Greg Lewicki, P.E.
