November 1010 NOTEBOOK 1 TETRA TECH November 19, 2010 Ms. Molly Orkild-Larson, AICP, RLA Senior Planner Garfield County Building & Planning Department 108 Eighth Street, Suite 401 Glenwood Springs, CO 81601 RE: Revised Major Impact Review for a Gravel Mine (MIPA-8-10-6545) Dear Molly: On behalf of Lafarge West, Inc., we are writing in response to your completeness review comments for the Cerise Mine Major Impact Review (MIPA-8-10-6545). Attached are four copies of the updated application. Below is a listing of your completeness review comments followed by an explanation, in italics, of how we have responded to each of your comments. General Submittal Requirements 1. Narrative - Please provide narrative on the following: • Number of years proposed for the gravel operation. The gravel operation is proposed to last 15 years and begin in 2012. We have added mine schedule information to the "Purpose of Application and Project Description" section of the Narrative • How much aggregate are you mining per year? How many tons total are you anticipating mining? Lafarge anticipates mining approximately 375,000 to 500.000 tons of aggregate per year for a total of up to 7,280,000 tons by the time mining is complete. This same information has been added to the `Purpose of Application and Project Description" section of the Narrative. In addition, we have provided information about how many tons of aggregate will be mined per phase. • What structures/equipment will be located on-site (batch plant, concrete plant, etc.) A list of all of the structures/equipment that may be located on-site has been added to the "Purpose of Application and Project Description" section of the Narrative. • Number of employees. There will be 20 to 35 Lafarge employees working at the Cerise Mine site and up to 10 asphalt plant employees on-site if and when the asphalt plant is brought on-site (the asphalt plant will not be operated by Lafarge and will only be brought on site if a specific job requires asphalt). This information has been added to the '`Purpose of Application and Project Description" section of the Narrative 1900 S. Sunset Street. Suite 1 F Longmont, CO 80501 Tel 303.772.5282 Fax 303.772 7039 www teti atech.com T T A TECH Page 2 of 5 Ms. Molly Orkild-Larson November 19, 2010 • Hours of operation. Is this application requesting to operate outside the hours designated by County code? If so, what hours of operation are you proposing? The Cerise Mine will operate under the County's standard hours of operation as described in the Land Use Code. The Narrative has been revised to reflect this information. • How does your phasing coincide with the Blue Pit? At what point do you anticipate the greatest impact from both pits? How will you mitigate this cumulative impact? How the phasing and anticipated timing of the phasing of the Cerise Mine coincides with the Blue Pit is easiest to understand in graphic form. Therefore, we have prepared a series of graphics entitled "Cumulative Impact Analysis Site Plans" and included this set of graphics in Section 15 of the application package. This series of graphics takes a look at the impact of mining on the area as a whole and therefore begins with showing current existing conditions in the area (Powers Pit and Blue Pit currently being mined) and then steps through each phase of the Cerise Mine in comparison to where we understand Western Slope Aggregates projects they will be in their process of mining Blue Pit. As shown in the graphics, the overall impact of mining on the area as a whole will change very little as the total area of disturbance does not significantly increase. Lafarge will simply be moving their area of mining from the Powers Pit to the Cerise Mine. The two mines are very similar in size. Western Slope Aggregate's plans involve expansion of the Blue Pit, however, it is our understanding that they will be concurrently reclaiming as they move forward with mining so as to minimize their impact on the area. We anticipate that there will be a 2± year period of time that the Cerise Mine and Blue Pit will be adjacent to eachother (approximately 2027-2029) However, the area in which they are adjacent to eachother is as far south as possible, away from the residential homes that are to the north. Lafarge has identified several steps that they will take to mitigate the impacts of the Cerise Mine on the area All of those mitigation techniques are outlined on pages 35 to 39 of the Narrative in response to Section 7-840, G of the Code. • What type of agricultural use is proposed? Crops? Grazing? The site will be reseeded with pasture grasses so that the land can be used to pasture horses as is desired by Clifford Cerise Ranch ('o, LLLP. the landowners We have added this sentence to the "Purpose of Application and Project Description" section of the Narrative. Article IV Application and Review Procedures Section 4-502 (D) Land Suitability Analysis 7. Water Provide the lease for Basin Ditch and water contract with Basalt Water Conservancy District. A copy of the lease agreement between the Clifford Cerise Ranch ('ompany, LLLP and Lafarge West. Inc is included in Section 16 of the application. Section 6 (on page 6) of the lease addresses the water that Lafarge has access to during the term of the lease Documentation from the Basalt Water Conservancy District indicating that the District has agreed to lease Lafarge water, is also included in Section 16 of the application TETRA TECH Page 3 of 5 Ms. Molly Orkild-Larson November 19, 2010 In addition, attached is a revised copy of the Land Suitability Analysis (Section 14 of the application). We modified section 7 about water use associated with the Cerise Mine. If the life of the gravel operation is longer than one year, then the County directs Applicants to provide a permanent, reliable potable water system. I strongly encourage you to investigate other options for water. Lafarge will obtain the water that they will be leasing from the Basalt Water Conservancy District from a couple of wells on the Cerise Mine site. One well will be used to meet the production needs on the site and the second well will provide potable water to the office building. We have updated section 7 of the Land Suitability Analysis to explain how water will be provided to the site. Section 4-502 (E) Impact Analysis 6. Effect on Existing Water Supply and Adequacy of Supply. See Section 4-502 (D)(7) Water above. The Impact Analysis Statement in Section 15 of the application has been updated to explain the plans for how water will be provided to the Cerise Mine site. 7. Effect on Groundwater and Aquifer Recharge Areas If the life of the gravel operation is longer than one year then the County directs Applicants to provide permanent waste water system. I strongly encourage you to investigate other options for waste water such as an ISDS. Lafarge will install an ISDS system to meet the sewer system for the restroom facility located in the office building on the site. In addition, portapottieswill be available on the site for workers to use. The Impact Analysis Statement in Section 15 of the application has been updated to reflect this and the ISDS Design for the site is included in Section 12 of the application. Article VII Standards Division 1 — General Approval Standards for Land Use Change Permits Section 7-102 Compliance with Comprehensive Plan and Intergovernmental Agreements How is this application consistent with the 2000 Comprehensive Plan. We have added information to our response to Section .7-102 of the Narrative to explain how the application is consistent with the 2000 Comprehensive Plan. Section 7-104 Sufficient Legal and Physical Water Supply See water sections above. A thorough response to Section 7-104 is provided in the Narrative (Section 9 of the application). Section 7-105 Adequate Water Supply See water sections above .1 thorough response to Section 7-105 is provided in the Narrative (Section 9 of the application). TETRA TECH Page 4 of 5 Ms. Molly Orkild-Larson November 19, 2010 Division 8 — Standards for Certain Types of Uses Section 7-840 Additional Standards Applicable to Gravel Extraction A. Water Quantity and Quality Impacts/Floodplain Impacts Please provide the following documents: • Stormwater Management Plan (not under the Erosion and Sediment Control tab as indicated in the application's narrative). A copy of the Stormwater Management Plan in Section 12 of the application. • Evidence that you meet Colorado Department of Public Health and Environment (CDPHE) Water Quality Control Division discharge requirements. A copy of the CDPS permit from CDPHE is provided in Section 26 of the application. • Spill Prevention Plan. A Spill Prevention Plan (SPCC) is provided in Section 27 of the application. • Letter from the applicable fire protection district stating that the proposed project has been adequately designed to handle the storage of flammable or explosive solids and gases and the methods comply with the national, state, and local fire code. A copy of the letter from the fire district is provided in Section 19 of the application. B. Air Quality • Evidence that the application meets the Department of Public Health and the Environment (CDPHE) Air Pollution requirements. We have updated the Narrative to better explain how the Cerise Mine will meet air quality standards (see pages 28 to 30). In addition, evidence that the Cerise Mine will meet CDPHE requirements is provided in Section 20 of the application. Included in Section 20 are the following documents: o Air Quality Statement prepared by Buys and Associates, as required by the County's Code. o Air permits for the equipment to be used at the Cerise Mine site. o A letter from Buys and Associates explaining how the site will meet CDPHE requirements regarding air quality D. Visual Impacts • Submit a Berming, Screening, and Buffering Plan. Since this application will be situated below an existing neighborhood it is critical that you demonstrate how you will mitigate visual impacts to surrounding parcels. Visual graphics illustrating how you plan to mitigate visual impacts would be beneficial. We have updated the Narrative to better explain how the Visual Impacts of the Cerise Mine will be mitigated (see pages 31 to 33). In addition, we have prepared a Berming, Screening and Buffering Plan; it is provided in Section 15 of the application. Lafarge also had a computerized visual impact study model prepared. The model uses 2' topographic contours that were obtained by Lafarge for the Cerise Mine site in conjunction with USGS topography for the areas around the site. The model then pulls in the proposed topographic features (mining cells as well as overburden and topsoil stockpiles) of the Cerise Mine per the proposed mining and reclamation plans Existing and proposed vegetation is also built into the model (existing trees shown in the model were located based on information pulled from Google Earth aerial mapping). Using the model, we can navigate to surrounding properties and look at the Cerise Mine site to get TETRA TECH Page 5 of 5 Ms. Molly Orkild-Larson November 19. 2010 a realistic view of what will be seen. As expected, the model shows that the entire site is not screened; however, it also shows that the screening and berming that is proposed is effective at mitigating the visual impacts. Screen shots from the model are provided in Section 15 of the application E. Impacts to the Road System • What will the impacts to CR 103 and SH 82 and how will you mitigate these impacts? We have updated the Narrative to better explain how the impacts to the road system from the Cerise Mine will be mitigated (see pages 33 to 35). For even more detailed information, please review the traffic study as it also discusses the traffic impacts and improvements that must be constructed or installed in order to address those impacts. Thank you for your assistance with this application. If you have any questions regarding any of the information submitted, please give me a call.

The Cerise Mine is located at the northeast corner of Highway 82 and County Road 103/Crystal Springs Road. The Cerise Mine is directly east of our existing Powers Pit. Operations at the Powers Pit are nearing completion and the Cerise Mine is planned to replace the Powers Pit. While not required by the County's Major Impact Review application process, Lafarge hosted a neighborhood meeting regarding our application on Thursday, July 22, 20I0 in a community room at the Carbondale Town Hall. We expanded our invitation list to include neighbors beyond the 200 foot notification radius required by the County to include most of the Wooden Deer Subdivision owners as they are the neighbors that will be most impacted by our proposed mine. Lafarge hosted the meeting because we believe it is important to listen to the concerns of the neighbors and incorporate their suggested ideas into our mining and reclamation plans as much as possible. The primary concern of most of the neighbors seems to be related to the fact that the existing Powers Mine, our proposed Cerise Mine and the Blue Pit (and the proposed expansion to the Blue Pit) are all along Highway 82, south of their properties. This is true; however, the reason for this is that this is where the mineable aggregate resource is located. Therefore, as you will read in our application, Lafarge will be taking steps to minimize the impacts of the Cerise Mine on the surrounding properties, Lafarge has worked to minimize the cumulative impacts of having two mining areas adjacent to each other and is willing to work with the Blue Pit to develop a comprehensive mining plan for the area.

GENERAL PROJECT DESCRIPTION Site Description: The Applicant proposes to mine gravel on an approximately 105 acres parcel located at the northeast corner of State Highway 82 (SH 82) and Crystal Spring Road. The parcel is zoned Rural and contains a residence and out buildings and a large portion of the property is presently being farmed. An existing gravel mine is adjacent and west of the proposed site and another gravel operation is east of the subject parcel along SH 82. Subdivisions within a mile of the property include Wooden Deer to the north and Ranch at Roaring Fork to the south. Portions of the property that are not in agricultural use consist mainly of sagebrush, juniper, and pinon. Crystal Spring Creek runs along the western side of the parcel and potentially may have wetlands. Mining: The Applicant proposes to mine approximately 100 acres in the southern portion of the site. Mining will consist of four phases and six to seven tons of material is to be extracted. The life of the pit will be 15 years and is scheduled to open in 2012. Upon on the opening of this pit, the adjacent mine (operated by LaFarge) will close. The mining operation will consist of a scale house, wash plant, concrete and asphalt plants. Materials will be mined to a depth of 100 feet (2 feet above ground water) and backfilled at a 3:1 slope. A 100 foot buffer from the property line and 50 foot setback from the ditch along the north perimeter of the mining area is proposed. Top soil/overburden is proposed to be stored in the setbacks. Native vegetative along Crystal Spring Road and portions of SH 82 will remain to provide screening. Reclamation: The Applicant proposes to reclaim the site as residential after mining is completed. Number of Employees: 25 to 45 employees (25-35 LaFarge employees and 10 batch plant employees) are anticipated to work on-site. LaFarge proposes to lease the batch plant to another company. Water: There are several options to serve the site with water; on-site well, well water from the gravel pit adjacent to the site, and/or ditch water. Waste Water: Septic vault and haul for waste water on-site is being considered. Access: From Crystal Spring Road. Traffic: It is anticipated that the majority of the truck traffic will turn left onto Crystal Spring Road and travel either north or south on SH 82. The County may require some improvements to Crystal Spring Road due to impacts from increased traffic. Neighborhood Meetings: Gravel mining can be controversial therefore it may be beneficial if the Applicant hold neighborhood meetings to answer questions from the public prior to the public hearings with the County. Required permits and studies include: A Fugitive Dust Plan/p\Permit Noise Analysis for compliance with State Statute DRMS Reclamation Plan Traffic Analysis Recorded Statements of Authority Air Emission Permits Vegetation and Wildlife Analysis State Highway Access Permit Hauler Affidavit (water/san/trash) REGULATORY PROVISIONS APPLICANT IS REQUIRED TO ADDRESS Major Impact Review - Article IV — see 4-101, 4-102, 4-103, 4-106, 4-501 (F), 4-502 Also see Article VII, Divisions 1 and 2 for general standards The Unified Land Use Resolution has a dedicated section regarding extraction activity requirements in section 7-840. 11.

(Lafarge) is submitting this Major Impact Review Application to Garfield County in order to permit a sand and gravel mine on the Clifford Cerise Ranch Co, LLLP property (Cerise property) located north of Highway 82 and east of County Road 103. Lafarge has a lease agreement with the Clifford Cerise Ranch Co, LLLP to mine the aggregate on the Cerise property, process it on-site, and have a concrete plant and temporary asphalt plant on-site. The Cerise property is approximately 98 acres; however, Lafarge is only permitting 65.48 acres of the property, all of which is located south of the Basin Ditch. As illustrated on the Site Plan map in Section 11 of the application, Lafarge will mine the site in five phases (Phase 1, Phase 2, Phase 3, Phase 4A, and Phase 4B). Following is a description of the mine phasing (due to the complicated nature of the phasing, it will be easiest to follow along with the description if you refer to sheets 3-10 of the Site Plan map found in Section 11 of the application). To begin, Lafarge will construct their access to the site off County Road 103. The access will cross Crystal Creek and so a small section of the creek will need to be piped and fill material will be used to construct the road. Lafarge will then strip the topsoil and overburden from the west half of the permit area and stockpile it. Next, Lafarge will excavate the aggregate from Phase 1 to create a tailings pond/detention pond to use for the life of the mine This tailings pond is needed before any aggregate can be processed; therefore, the aggregate mined from Phase 1 will be stockpiled on-site until all of Phase 1 is excavated. The aggregate processing plant will be set-up, in the area that will be mined as Phase 3, and the aggregate from Phase 1 will then be processed. The rest of the plant site structures, including the concrete plant, will be constructed west of the aggregate processing plant (when the temporary asphalt plant is on-site, it will be located here as well). Mining on Phase 2 will begin after the Phase 1 aggregate is processed. Once Phase 2 is mined, the aggregate processing plant will move to the floor of the Phase 2 pit (all of the other plant site improvements will remain in place) and mining on Phase 3 will begin. Phase 4A will be a primary storage place for overburden from previous phases; therefore, the overburden from Phase 4A will be moved into Phase 3 to construct reclamation slopes before Lafarge begins mining Phase 4A. Upon the completion of Phase 4A mining, the concrete plant and other plant site improvements will be removed from the site and Phase 4B mining will begin. Following the mining of phase 4B, final reclamation of the entire site will occur. The site will be reseeded with pasture grasses so that the land can be used to pasture horses as is desired by Clifford Cerise Ranch Co, LLLP, the landowners. Lafarge's plan is to initiate mining of the Cerise site in the spring of 2012. They anticipate mining the site in approximately 15 years followed by two years of reclamation; however, this is just an estimate due to the fact that the rate of mining and overall life of the mine is dependent upon demand and market conditions. The table on the following page provides more detail regarding the anticipated schedule in relation to each phase and the amount of material to be mined per phase. Based on this anticipated schedule, Lafarge will mine approximately 375,000 - 500,000 tons per Cerise Mine Major Impact Review Application Page 1 of 43 year. Historically, Lafarge has mined up to 660,000 tons per year of aggregate from their Powers Mine site which is just west of the Cerise Mine site; therefore, Lafarge believes this estimate of tons per year for the Cerise Mine site is achievable.

It should be noted that the list of equipment is estimated and during the life of the mine, Lafarge may modify the numbers and type of equipment on site to facilitate mining and reclamation. Equipment: Loaders (4) Diesel Powered Generator Set as needed (2) Dozer (1) Scrapers (2-4) Grader (1) Backhoe (1) Water Truck (1) Pumps as needed (2-3) Skidsteer (1) Structures: Aggregate Processing Plant including a Crushing Plant and Wash Plant Ready Mix Concrete Plant Temporary Asphalt Plant Conveyors and Feeders Office/Scalehouse (1) with restroom facility Scale MCC Building Fuel Storage Tank w/Secondary Containment Trash Dumpster Portable Toilets (2- 4) to be located near portable equipment or the face of the mine There will be up to 45 people working at the Cerise Mine site; 20-35 of these people will be Lafarge employees who will be mining the aggregate and operating the aggregate processing plant and Cerise Mine Major Impact Review Application Page 2 of 43 concrete plant. The other potential 10 people will only be working on the site if the temporary asphalt plant is brought on to the site to provide asphalt for a specific job. If and when an asphalt plant is brought on site, it will be operated by an independent contractor, not Lafarge. Consistent with the Garfield County Code, the Cerise Mine will operate 7:00 a.m. to 8:00 p.m. Monday through Saturday with crushing, digging, and heavy hauling allowed from 7:00 a.m. to 6:00 pm allowing for administrative and maintenance activities to take place until 8:00 p.m. No operations except emergency maintenance to ensure the integrity of operating equipment will take place on Sunday. Responses to Article VII Applicable Standards and Criteria Following is a listing of the applicable standards/criteria found in Article VII of the Garfield County Code followed by our explanation in italics of how each of the standards will be met at the Cerise Mine. Section 7-101 Compliance with Zone District Use Restrictions. The land use change complies with applicable zone district use restrictions and regulations in Article III, Zoning. The Cerise property is in the Rural Zoning District and a gravel extraction facility is considered a permitted use subject to Major Impact Review. The maximum height of structures in the Rural Zone District is 40 feet. The Ready Mix concrete plant, as shown on the elevation included in the Site Plan set, is 45 feet tall. However, the plant will be located more than five feet below existing grade to mitigate the extra height. If needed, at the time of building permit, a height variance will be requested for this 45 foot tall structure. Section 7-102 Compliance with Comprehensive Plan and Intergovernmental Agreements. The land use change is consistent with applicable provisions of the Garfield County Comprehensive Plan and any intergovernmental agreements between the County and a municipality that applies to the area where the use will occur. The Cerise Mine will be consistent with the Garfield County Comprehensive Plan 2000. According to the Natural Resources map associated with the Comprehensive Plan, the Cerise Property has an "Aggregate, Sand and Gravel Designation ". The Proposed Land Use Districts Map for the Comprehensive Plan indicates that the property is designated for Res M (6 to <10 acres/dwelling unit). However, according to CRS 34-1-305(1), "no board of county commissioners, governing body of any city and county, city, or town, or other governmental authority which has control over zoning shall, by zoning, rezoning, granting a variance, or other official action or inaction, permit the use of any area known to contain a commercial mineral deposit in a manner which would interfere with the present or future extraction of such deposit by an extractor." Therefore, per State law, the mining of the aggregate mineral resource must occur prior to any other developed use, which, in this case, the County indicates should be residential. In addition, below is a listing of the applicable provisions from Section III, Part 9 (Natural Resource Extraction) of the Garfield County Comprehensive Plan 2000 followed by an explanation of how the Cerise Mine will comply with the stated goal, objectives, policies and programs. Cerise Mine Major Impact Review Application Page 3 of 43 Goal: Garfield County recognizes that under Colorado law, the surface and mineral interests have certain legal rights and privileges, including the right to extract and develop these interests. Furthermore, private property owners also have certain legal rights and privileges, including the right to have the mineral estate developed in a reasonable matter and to have adverse land use impacts mitigated. The Clifford Cerise Ranch Co, LLLP owns the Cerise property and they want to exercise the right afforded them by CRS 34-1-305(1) (as quoted above) to mine the sand and gravel resource found on their property. Therefore, they signed a lease with Lafarge West, Inc. to have them mine the property. Adverse land use impacts associated with the mine will be mitigated by Lafarge as. explained below in response to Objective 9.1. Objectives: 9.1 The County will require adequate mitigation to address impacts of mineral extraction on private property owners, without undue burden on the legal rights of mineral lessees. The Cerise Mine plan has incorporated the following mitigation measures into their plan to address the impacts of mineral extraction on surrounding private property owners: • Access to the site will be onto County Road 103, south of any residential streets or driveway access, so the majority of trucks coming and going to the site on County Road 103 will not pass any existing homes (the only time trucks will drive north on County Road 103 would be to deliver materials to a site in that direction). • There is a significant elevation difference between Highway 82 and the elevation of the Cerise property where the mining will occur. As a result, this ridge will serve as a screening "berm" between the mining activity and the highway and all other land south, southeast and southwest of the site. • When the site is initially prepared for mining, the topsoil and overburden from the west side of the permit area will be used to create large berms on the north and west edges. These berms will be revegetated and help buffer the site from neighbors to the north. • Lafarge is proposing to relocate their aggregate processing plant and the location for the temporary asphalt plant into the floor of the mine when the mining of Phase 2 is complete to help screen these operations from surrounding properties. • All State and County noise standards will be met. • All State air quality standards will be met and the appropriate air quality permits will be obtained. • The site will operate during the hours of operation as permitted by the Garfield County Code. 9.3 The County will ensure that mineral extraction activities will not adversely affect the natural environment, including air quality, water quality, wildlife habitat or important visual resources. The Cerise Mine will comply with the applicable local, state and federal permit regulations related to protection of the natural environment including air and water quality. Impacts on significant wildlife habitat will be minimized by keeping mining activity out of the adjacent Crystal Creek riparian corridor. Due to an elevation change and existing, mature vegetation along the west edge of the southern portion of the site, the mine will have little to Cerise Mine Major Impact Review Application Page 4 of 43 no visual impact on properties to the south of the Cerise property. To help screen the site from the northwest (along CR 103) and north, Lafarge is proposing vegetated berms along the west and north edges of the site. The berms will be constructed at the beginning of operations and remain in place through the life of the mine until the topsoil and overburden material in the berms is needed to complete reclamation of the site. In addition, Lafarge is proposing to relocate the aggregate processing plant to the floor of the mine prior to mining Phase 3 in order to further mitigate the impact of the mining operations on the surrounding property owners. Policies: 9.1 Garfield County, to the extent legally possible, will require adequate mitigation to address the impacts of mineral extraction on adjacent land owners. These measures may include the following: A. Landscaping and screening; B. Modification of phasing or area to be mined; C. Roadway improvements and signage; D. Safe and efficient access routes; E. Drainage improvements to project surface and groundwater. The Cerise Mine is proposing each of the above described measures as follows: A. Vegetated berms will be provided on the north and west edges of the property to help screen the mining activities from off-site. B. The site is planned to be mined in phases and Lafarge will reclaim the slopes of the mine as they proceed. In addition, Lafarge has proposed to relocate the aggregate plant to the floor of the mine prior to mining Phase 3. Having the plant on the floor of the mine will significantly help mitigate impacts on surrounding property owners because the floor of the mine will be approximately 80' below existing grade. C. A traffic study was prepared for the project and all improvements and signage recommended in the study will be installed. D. The site will take access onto County Road 103 which connects to Highway 82. The access is located along County Road 103 where there is good site distance and trucks using the access will not need to pass any existing homes as they travel to and from Highway 82. Lafarge did not propose a direct access to Highway 82 as that could generate safety concerns and probably wouldn't be permitted by CDOT (proposing an additional access onto the highway is not as safe as utilizing and existing access point). E. A drainage report was prepared for the property to ensure that surface water will be properly handled so as to not create an impact on surrounding property owners. No groundwater will be exposed with the mining of the site. 9.2 Garfield County, in coordination with relevant special districts, authorities and municipalities, will require that developers of energy or mineral extraction projects finance the construction and operation of any public improvements which, now or in the future, will be required by their projects. Lafarge will enter into a public improvements agreement with the County to address Lafarge's financial obligations for public improvements required as a result of the Cerise Mine. 9.4 Dust, odors and fumes should be contained within the extraction site generating such Cerise Mine Major Impact Review Application Page 5 of 43 emissions and should not negatively affect any surrounding land use. Lafarge will meet all applicable State and County regulations pertaining to dust, odor and fumes. 9.5 Any proposal regarding mineral extraction that cannot mitigate adverse impacts may be denied based on a finding of incompatibility, for the following reasons: A. Adversely affecting the desirability of the immediate neighborhood or the entire community. B. Impairing the stability or value of existing adjacent properties; C. Adversely affecting the quality of life of existing adjacent residences; D. Showing a lack of quality or function in operational planning and/or design; E. Creating a public danger or nuisance to surrounding areas; F. Altering the basic character of adjacent land uses or the entire community Lafarge will mitigate potential adverse impacts and take steps to make the Cerise Mine compatible with adjacent land uses. The mitigation steps to be taken are all outlined in this narrative in response to Section 7-840, G, 6 and 7 of the Code (see pages 36-39). In addition, we respond as follows to items A-F above: A. Lafarge has been operating the Powers Mine which is right next to the Cerise Mine site for the last several years and has a record of being a good neighbor as Lafarge does not receive complaints about their operation from neighbors. In addition, the Powers Mine existed prior to the residential development that has occurred around it and so the homeowners knew that mining was in the area when they purchased their homes. Lafarge will be finished with mining at the Powers site before they mine the Cerise site. Therefore, the character of the area will not be changed by the Cerise Mine. Instead, Lafarge's aggregate mining activities will just continue in the area. However, it is very important to point out that the way that Lafarge will mine the Cerise site will be different than how the Powers site was mined. New techniques and technology will be utilized so that the mining activities will result in less impact and the mine site will be easier to reclaim. B. The Cerise Mine will not impair the stability or value of existing adjacent residences because mining existed in the area before the residences were built. Mining as a land use is just continuing in the area because that is where the gravel resource in the County is located. The Comprehensive Plan for the County clearly indicates that the property has an `Aggregate, Sand and Gravel Designation ". While home owners have a choice as to where to buy or build a home, the gravel industry can't decide where the aggregate resource is located and State law indicates that the resource must be mined prior to using the land for any other use. C. As described on pages 36-39 of this Narrative, Lafarge is taking steps to mitigate potential impacts of the mine on surrounding property owners so that the mining operation doesn't diminish the quality of life those property owners have always had since their homes were built in an area with active aggregate mining. D. Lafarge will utilize their best management practices to mine the Cerise site so that they are good neighbors as they operate in a manner that is both efficient and environmentally conscientious. Lafarge always strives to exceed industry practices and stand out as a world leader in their mining practices. In laying out the mine plan, Lafarge's goal was to maximize the amount of reserve mined from the property while Cerise Mine Major Impact Review Application Page 6 of 43 minimizing the impacts of mining on surrounding properties. Following are some specific ways that Lafarge will demonstrate high quality operational planning and design at the Cerise Mine. To begin, their plan calls for the creation of a single tailings area that will last the life of the mine. This will allow Lafarge to mine all potential reserves on the Cerise site as quickly and efficiently as possible to minimize the amount of time that they disturb the site. In addition, Lafarge has planned to mine the site in phases to allow for mining to occur in a controlled and systematic way. At the start of operations, they will strategically create vegetated berms on the north and west edges of the site to help screen the active mining areas and plant site. As mining proceeds through the phases, as much as possible, they plan to keep the earthmoving activity down in the mining cell to help minimize impacts. At all times, their aggregate plant will be below grade. To start off it will sit ten to fifteen feet below grade on top of the aggregate resource. Then, prior to mining Phase 3 when enough space is created, the plant will be moved to the floor of the mine which will be approximately 80 feet below existing grade. This will help minimize visual, noise, and dust impacts and create a more efficient mining operation as loads of product will not need to be transported by truck or conveyor to the top of the mining cell to be processed. Lafarge has worked very hard to plan the mine phasing and operation to be efficient while limiting potential impacts. In addition, as the site is being mined, Lafarge will concurrently reclaim the mined areas as much as possible. Overburden will be used to create 3:1 reclaimed slopes and the slopes will be revegetated. This will help minimize the visual impacts of the operation as well as speed up the completion of reclamation after all mining is complete. Therefore, it is clear that Lafarge will utilize the latest mining and processing techniques at the Cerise Mine and there will be no lack of quality or function in operational planning and/or design. E. As is described above and throughout this narrative, significant steps will be taken by Lafarge to mitigate potential negative impacts; no public danger to surrounding areas will be created by the Cerise Mine and all nuisance related issues will be mitigated. F. The basic character of the community will not be altered with the mining of the Cerise property. Aggregate mining is an existing land use in the area that has existed longer than most of the adjacent residential uses in the area. Lafarge will be reclaiming the Powers Mine when they begin to mine the Cerise site and Western Slope Aggregates will be concurrently reclaiming the Blue Pit as they proceed through their mining operation. Therefore, the overall acreage of land that will be exposed for mining will be very similar to what it has historically been in this area. In addition, According to Section 9 of the July 14, 2010 version of the Garfield County Comprehensive Plan 2030 document, the Mineral Extraction Vision states: "Resource extraction, including oil and gas development, has been encouraged to remain in the county due to their contribution they make to the county's overall goal of having a diverse and stable economy. While resource industries are welcomed in the county, they have been expected to Cerise Mine Major Impact Review Application Page 7 of 43 fairly mitigate negative impacts that might have resulted due to their operations." Lafarge has been positively contributing to the Garfield County economy for many years. They currently operate at various mines throughout Garfield County and more specifically the Powers Mine at the northeast corner of County Road 103 and Highway 82. Mining at the Powers Mine site will soon be completed and Lafarge is requesting approval of the Cerise Mine to be able to continue to operate in this area. By permitting the Cerise Mine, Lafarge will be able to continue to provide employment to the current employees of the Powers Mine as well as many third party employers who utilize Lafarge products in their work. In addition, by permitting the Cerise Mine, Lafarge will be able to continue to provide aggregate construction materials needed in the County. While Western Slope Aggregates' Blue Pit is currently operating in this area (east of the Cerise Mine), it is important to continue to have more than one provider of aggregate materials in the area to maintain competition so that the price of materials is kept under control. In addition, as stated above in response to the Garfield County Comprehensive Plan 2000 Objectives, Lafarge will be taking steps to mitigate potential negative impacts associated with the Cerise Mine to prevent impacts on the surrounding properties. Section 7-103 Compatibility. The nature, scale, and intensity of the proposed use are compatible with adjacent land uses and will not result in an adverse impact to adjacent land. Please refer to the "Section 7-840, G: Compatibility with Surrounding Land Uses" response on page 36 of this Narrative for a complete explanation of how the Cerise Mine will be compatible with other uses in the area. Section 7-104 Sufficient Legal and Physical Source of Water. All applications for land use change permits requiring a water demand of 8 (eight) single family equivalents or less (one single family equivalent equals 350 gallons per day) shall have an adequate, reliable, physical, long term and legal domestic water supply to serve the use. Lafarge has access to 29.5 acre feet of Basin Ditch water through their lease agreement with the Cerise family. The Basin Ditch is located on the north end of the project. Because the water is currently used for irrigation on the property, it would need to be converted through water court to be used for any production purposes at the Cerise Mine site. Therefore, Lafarge plans to just continue to use this Basin Ditch water to irrigate the vegetation during the on-going reclamation activities at the mine site. A copy of the lease between Lafarge and Clifford Cerise Ranch Co, LLLP with information about the availability of the Basin Ditch water is included in Section 16: Water Information of the Major Impact Review application. In lieu of using the ditch water for production, Lafarge is going to lease 40.5 acre feet of water from the Basalt Water Conservancy District to supply the site with all of the water needed to meet the operational and domestic use needs. The 40.5 acre feet is the consumptive use amount calculated by Applegate Group (see water requirements letter in Section 16 of the application). This is the maximum amount of water that would ever be needed at the Cerise Mine site if all proposed activities were producing at full capacity and there was no recycled water being used. However, Lafarge always institutes recycling systems and is generally able to recycle more than 50% of the water used in processing. Therefore, 40.5 acre feet will be more than enough water to operate the site and meet the domestic water needs. Documentation from the Basalt Water Conservancy District Cerise Mine Major Impact Review Application Page 8 of 43 indicating that the District has agreed to lease water to Lafarge is also included in Section 16 of the application. The water that Lafarge will lease from Basalt Water Conservancy District will be obtained from a couple of wells on the property, one well will provide production water and the other will provide potable water for domestic use. Test wells were drilled for both of these proposed wells in order to test the quantity and quality of water that could be obtained. Based on the water quality results from the tests run on a water samples taken from the test wells, the water is suitable for use as a potable water source with use of a simple water treatment and filtration system. More detailed information about the water quality test results is included in Section 16 of the application. In addition, a 24 hour pump test was run on both wells and it was determined that the aquifer and wells can provide an ample supply of water to support the Cerise Mine. The pump test results can also be found in Section 16. Lafarge is applying for the required well permits for both the production and potable water wells and copies of those permits will be provided to the County as soon as they are issued by the State. Documentation from the Basalt Water Conservancy District indicating that the District has agreed to lease water to Lafarge and a copy of the lease between Lafarge and Clifford Cerise Ranch Co, LLLP with information about the availability of the Basin Ditch water is included in Section 16: Water Information of the Major Impact Review application. A. Determination of Reliability of Water Supply. In determining adequacy of the proposed water supply the following considerations shall apply. 1. Peak Usage. Peak demands projected to service the total development population. 2. Adequacy of Water Source. In addition to the requirements of the State Engineer and County Health Department, the following provisions shall be used to evaluate the adequacy of the water source intended to serve the proposed development. a. The average daily demand of the entire service area and the proposed development shall be based upon 350 gpd per residential unit, or [75] gpd per capita, whichever is greater. b. The average daily demand for commercial and industrial uses shall be reviewed based on the anticipated demand of the proposed development, based on standard engineer's criteria. 3. Quality of Water Source. Water supplies shall be treated by a method acceptable to conform to minimum State standards. The County may require test wells. 4. Irrigation Water. The demand for irrigation water shall be based upon the type of vegetation to be maintained, soil characteristics, the historic yield of the property and available water rights. 5. Fire Protection Requirements. The water supply demand for fire protection shall be based upon recognized and customary engineering standards and requirements of the applicable fire protection district. Subdivision developments shall comply with the provisions of Section 7-403, Fire Protection, of this Article. To meet the needs of the operational consumptive uses at the Cerise Mine site, Lafarge will lease water from the Basalt Water Conservancy District for use at the Cerise Mine. Please see Section 16 for documentation that the Basalt Water Conservancy District approved Lafarge's request to lease water. In addition, as part of Lafarge's lease to mine the Cerise property, they have access to Cerise Mine Major Impact Review Application Page 9 of 43 29.3 acre feet of Basin Ditch water. A copy of the lease between Lafarge and Clifford Cerise Ranch Co, LLLP with information about the availability of the Basin Ditch water is also included in Section 16. Section 7-105 Adequate Water Supply. An adequate water supply plan shall be required for any preliminary or final approval of an application for rezoning, planned unit development, limited impact or major impact review, development or site plan, or similar application for new construction. This section shall apply to all development permits which require a water demand in an amount of more than 8 (eight) single-family equivalents where 1 (one) single-family equivalent equals 350 gallons of water per day (Resolution 2010-29). Lafarge will have two wells on the Cerise Mine site. A well located in the southwest corner of the property will be used to supply the water needed to operate the Cerise Mine and a well drilled in the plant site area will provide potable water to the office. A. Authority. The Board of County Commissioners, pursuant to §29-20-301, et seq. C.R.S., as amended, shall not approve an application for a development permit unless it determines in its sole discretion, after considering the application and all of the information provided, that the applicant has satisfactorily demonstrated that the proposed water supply will be adequate. Nothing in this section shall be construed to require that the applicant own or have acquired the proposed water supply or constructed the related infrastructure at the time of the application. Noted. B. Water Supply Requirements. All applications for development permits shall include the estimated water supply requirements for the proposed development in a report prepared by a registered professional engineer licensed to practice in the State of Colorado qualified to perform such work. The report shall include the following: 1. An estimate of the water supply requirements for the proposed development through build- out conditions. The estimated operational consumptive uses of water at the Cerise Mine are as follows: For more information, please see the Water Requirements Letter prepared by Applegate Group, Inc. in Section 16 of the application. 2. A description of the physical source of water supply that will be used to serve the proposed Cerise Mine Major Impact Review Application Page 10 of 43 Assumption 1 Annual Water Use Requirement Aggregate Production 500,000 tons 14.7 acre-feet Concrete Production 100,000 cubic yards 15.3 acre-feet Dust Control 400,000 gallons/month for 8 months 9.8 acre-feet Truck Washing 20,000 gallons/month for 8 months 0.5 acre-feet Domestic 5,000 gallons/month 0.2 acre-feet Total Annual Operational Consumptive Use 40.5 acre-feet For more information, please see the Water Requirements Letter prepared by Applegate Group, Inc. in Section 16 of the application. 2. A description of the physical source of water supply that will be used to serve the proposed Cerise Mine Major Impact Review Application Page 10 of 43 development. Lafarge will lease 40.5 acre feet of water from the Basalt Water Conservancy District. Please see the documentation from the Basalt Water Conservancy District in Section 16 of the application for proof that the District has agreed to lease the water to Lafarge for the Cerise Mine site. Basalt Water Conservancy District is in the process of drafting a contract for Lafarge to sign. The leased groundwater will be obtained via a couple of wells that Lafarge will install on the Cerise Mine site. Copies of the well permits will be provided to the County as soon as they are issued by the State. 3. Water quality shall be demonstrated by complying with the Colorado Department of Public Health and Environment's drinking water standards for all development permits requiring water demand of 8 SFE or greater. Two test wells were drilled on the property. The November 16, 2010 letter from EnviroGroup Limited (see Section 16, Water Well Documentation) documents the water quality analytical results from water samples taken from the two test wells. The water quality tests required by CDPHE were run on the water samples and, as stated in the letter, the water will be suitable for use as drinking water. 4. An estimate of the amount of water yield projected from the proposed water supply under various hydrologic conditions. As indicated in the contract that Lafarge received from the Basalt Water Conservancy District, the District will lease them guarantee them 40.5 acre feet of water per year. Please refer to the November 17, 2010 letter report from EnviroGroup Limited (Section 16, Water Well Documentation), which documents the results of two 24-hour pumping tests. The pumping tests demonstrate a more than adequate supply of water available for the project, regardless of seasonal variations in hydrologic conditions. 5. Water conservation measures, if any, that may be implemented within the development. There will be a wash plant at the Cerise Mine site that will have a thickener tank installed within the plant system. This type of tank/system enables solids to settle out of the process water used within the plant so that the water can be re -used within the production processes of the plant. Approximately 50% of all water used within the wash plant will be recycled with the use of a thickener tank. Additionally, all other process water on site will be diverted to the silt pond. Solids will settle in the pond and then the water will be re -used for various on-site processes. 6. Water demand management measures, if any, that may be implemented within the development to account for hydrologic variability. Lafarge does not anticipate the need to implement water conservation or water demand management measures in response to hydrologic variability (dry year conditions). Lafarge obtained a water allotment contract from the Basalt Water Conservancy District (BWCD) to allow continued diversion of water when a water right call is placed on the Roaring Fork or Colorado River in response to dry year streamflow conditions. In the event of an extreme dry year that results in an unforeseen reduction in the yield of the BWCD water right portfolio, BWCD may develop and adopt a temporary water conservation plan to be implemented by its contractees. Lafarge will follow any such temporary conservation plan and will reduce its demand accordingly. Cerise Mine Major Impact Review Application Page 11 of 43 7. Proof of legal water supply shall include but may not be limited to an approved substitute water supply plan contract, approved augmentation plan, approved well permit, a summary of consultation from water court, or a legally adjudicated domestic water source. The water leased from the Basalt Water Conservancy District will be used as makeup credits for the water removed from the groundwater system and the Cerise Mine will automatically be covered by Basalt Water Conservancy District's Substitute Water Supply Plan. In addition, Lafarge is in the process of applying for well permits for the two wells that will provide water to the Cerise Mine site. Included in Section 16, Water Well Documentation, is a letter from Bence Close with EnviroGroup regarding the Aquifer Pumping Tests. In the letter, Mr. Close indicates that based on the estimated water demands, the productivity of the existing wells or new wells would not be a limiting factor in obtaining well permits to satisfy the project needs. Therefore, we do not anticipate any problems obtaining the required well permits from the State and the approved well permits will be provided to the County prior to final approval of the application. Also in Section 16 is documentation from the Basalt Water Conservancy District verifying that the District's Board approved Lafarge's request to lease water and a copy of the proposed water lease contract. 8. Such other information as may be required by the Board of County Commissioners. Lafarge will respond if additional information is requested by the Board. C. Water Supplied by Water Supply Entity Requirements. If the development is to be served by a water supply entity, the Board of County Commissioners may allow the applicant to submit, in lieu of the report required by Section 7-105(B), a letter prepared by a registered professional engineer licensed to practice in the State of Colorado qualified to perform such work from the water supply entity stating whether the water supply entity is willing to commit and its ability to provide an adequate water supply for the proposed development. The water supply entity's engineer shall prepare the letter if so requested by the applicant. At a minimum, the letter shall include: 1. An estimate of the water supply requirements for the proposed development through build- out conditions; 2. A description of the physical source of water supply that will be used to serve the proposed development; 3. An estimate of the amount of water yield projected from the proposed water supply under various hydrologic conditions; 4. Water conservation measures, if any, that may be implemented within the proposed development; 5. Water demand management measures, if any, that may be implemented to address hydrologic variations; and 6. Such other information as may be required by the Board of County Commissioners. 7. In the alternative, an applicant shall not be required to provide a letter or report identified pursuant to Sections 7-105(B) and 7-105(C)(1) — (6) above if the water for the proposed development is to be provided by a water supply entity that has a water supply plan that: a. Has been reviewed and updated, if appropriate, within the previous ten years by the governing board of the water supply entity; b. Has a minimum twenty-year planning horizon; Cerise Mine Major Impact Review Application Page 12 of 43 c. Lists the water conservation measures, if any, that may be implemented within the service area; d. Lists the water demand management measures, if any, that may be implemented within the development; e. Includes a general description of the water supply entity's water obligations; f. Includes a general description of the water supply entity's water supplies; and g. Is on file with the local government. No response required, please see responses to Section 7-105(B). D. Determination of Adequate Water Supply. The Board of County Commissioners' sole determination as to whether an applicant has a water supply that is adequate to meet the water supply requirements of a proposed development shall be based on consideration of the following information: 1. The documentation required by Sections 7-105(B) and 7-105(C) (Resolution 2010-29); 2. A letter from the state engineer commenting on the documentation required pursuant to Sections 7-105(B) and 7-105(C) (Resolution 2010-29); 3. Whether the applicant has paid to a water supply entity a fee or charge for the purpose of acquiring water for or expanding or constructing the infrastructure to serve the proposed development; and 4. Any other information deemed relevant by the Board of County Commissioners to determine, in its sole discretion, whether the water supply for the proposed development is adequate, including, without limitation, any information required to be submitted by the applicant pursuant to applicable local government land use regulations or state statutes. The Basalt Water Conservancy District (BWCD) has agreed to lease Lafarge the water required to meet the projected consumptive use requirements of the Cerise Mine site. Documentation from the BWCD verifying Board approval of Lafarge's request as well as a proposed contract issued by BWCD are included in Section 16 of the application. The water that Lafarge will lease from BWCD will be obtained from a couple of wells on the property; one well will provide the production water and the other will provide potable water for domestic use in the office. In October 2010, Lafarge had two test wells installed on the site in the approximate locations of the wells that will be formally permitted through the State. Water quality tests were run on water out of the test wells and the water was found to be suitable for use as a potable water source with use of a simple water treatment and filtration system. More detailed information about the water quality test results can be found in Section 16 of the application behind the Water Well Documentation divider. A 24 hour pump test was also run on both wells and it was determined that the aquifer and wells can provide an ample supply of water to support the Cerise Mine. The pump test results can also be found in Section 16 behind the Water Well Documentation divider. In addition, Bence Close with EnviroGroup has written a letter regarding the Aquifer Pumping Tests. In the letter, Mr. Close indicates that based on the estimated water demands, the productivity of the existing wells or new wells would not be a limiting factor in obtaining well permits to satisfy the project needs. Therefore, we do not anticipate any problems obtaining the required well permits from the State and the approved well permits will be provided to the County prior to final approval of the application. The water leased from the BWCD will be used as makeup credits for the water removed from the ground Cerise Mine Major Impact Review Application Page 13 of 43 water system and the Cerise Mine will automatically be covered by the BWCD's Substitute Water Supply Plan because both wells will draw water out of Area A of their District. Section 7-106 Adequate Central Water Distribution and Wastewater Systems. The land use change shall be served by water distribution and wastewater systems that are adequate to serve the proposed use and density. Wells will be used to provide the required water to the site for both operational needs and potable water. In addition, Basin Ditch water will be available for operational need uses. A septic system will be installed in the plant site area for the restroom facilities in the office building and several porta potties will be located throughout the site for use by employees working in the field. See responses below for more details. A. Water Distribution System Standards. 1. Central Water Distribution System Preferred. Where water service through a water supply entity is not physically or economically feasible, a central well and distribution system is preferred over individual wells (Resolution 2010-29). There is no nearby public potable water system for the Cerise Mine site to tie onto. Therefore, Lafarge will use a well to supply potable water to the office at the Cerise Mine site. 2. Central Water Distribution System Required. The following conditions require connection to a central water system. a. Proximity to Central System. The property is located within 400' of a central water system, the system is available and adequate to serve the proposed development, and connection is practicable and feasible. b. 15 or More Dwelling Units. Central water will be required for residential developments consisting of fifteen (15) or more dwelling units. Not applicable; the property is more than 400' away from a central water system. 3. Design. The water distribution system shall be designed by a qualified professional engineer licensed by the State of Colorado and shall be approved by the Colorado Department of Public Health and Environment and the County. An engineer will design a system to convey the water from the potable water well to the office building. B. Wastewater System Standards. 1. Central Sewer System Preferred. Every effort shall be made to secure a public sewer extension. Where connections to an existing public sewer are not physically or economically feasible, a central collection system and treatment plant is preferred. The Cerise Mine is not in close proximity to a public sewer system. Therefore, the restroom facilities in the office will be tied to a septic system and port -a potties will be provided on the site for employees to use. 2. Central Sewer System Required. The following conditions require connection to a central sewer system. a. Proximity to Central System. The property is located within 400' of a central sewer system, the system is available and adequate to serve the proposed development, and connection is practicable and feasible. Cerise Mine Major Impact Review Application Page 14 of 43 b. ISDS Not Suitable. The property is not suitable for a septic system, or individual sewage disposal system (ISDS). Septic systems or individual sewage disposal systems are not permitted on parcels less than one (1) acre in size. Not applicable; an ISDS is proposed and has been designed for the site. 3. Design. The wastewater system shall be designed by a qualified professional engineer licensed by the State of Colorado, and reviewed by the County Planning Department. The system shall be designed in compliance with the standards established by the Colorado Department of Public Health and the Environment. Site location approval shall be obtained from the Colorado Water Quality Control Commission for systems requiring their approval. a. The collection system shall not be designed for less capacity than the anticipated maximum daily sewage flow or treatment requirements. Where guidelines and standards are not available, the design intended for use shall be reviewed by the County Planning Department. b. Collection systems shall be designed and sized to comply with the guidelines and requirements of the applicable service provider. Approval of the proposed system by the service provider shall be a recommended condition of approval by the County Planning Department. 1. Collection systems shall be sized to meet present and future demands of the proposed development. Oversizing for likely extensions may be required. 2. The constructed systems shall minimize, unless otherwise specified by the service agency. The proposed ISDS has been designed by an engineer licensed to practice in Colorado. The system was designed to meet CDPHE requirements and it has been placed on the site to meet the locational requirements of the Water Quality Control Commission. Please see Section 12 of the application for the ISDS design report. 4. Occupancy Restrictions. Where connection to a central collection and treatment system is proposed and approved, but not available until installation or expansion of such facilities is completed, no uses shall occupy the lot until the collection and treatment system is available to service the proposed use. Porta potties will be available on-site at all times once activity on the site begins and then the septic system will be installed for the restroom in the office building as soon as possible. 5. Repair and Maintenance. Adequate provisions for repair and maintenance of the wastewater system shall be required. Lafarge will have a contractor service the septic system and port -a potties on a regular basis. 6. Public Systems. Not applicable; tying into a public system is not an option for the Cerise Mine. 7. Private Systems. A septic system, or individual sewage disposal system (ISDS), permitted under these Regulations shall comply with the Garfield County Individual Sewage Disposal System Regulations. The ISDS system will comply with the Garfield County Individual Sewage Disposal System Regulations. 8. Minimum Lot Requirements for Private Systems. Unless otherwise provided in these Regulations, the proposed system shall comply with the minimum lot requirements set forth in Table 7-105 B, below. Cerise Mine Major Impact Review Application Page 15 of 43 a. The minimum lot area may be increased and the number of uses permitted under the applicable zoning district may be decreased if the County Health Department determines that the proposed use of septic tanks or other individual sewage treatment facilities could result in a danger to public health. The ISDS system complies with the minimum lot requirements. Section 7-107 Adequate Public Utilities. Adequate public utilities shall be available to serve the land use change. Lafarge will coordinate with Holy Cross Energy to get electric service to the site. Section 7-108 Access and Roadways. All roads shall be designed to road design standards set forth in Section 7-307 and all roads shall be reviewed by the County Engineer. (2009-53) B. Access to Public Right -of -Way. All lots and parcels shall have access to a public right-of-way. A new lot or parcel is not proposed with this Major Impact Review application; however, the Cerise Mine will have access onto County Road 103. C. Safe Access. Access to and from the use shall be safe and in conformance with access standards set forth in the [title of new road/bridge standards]. Where the land use change causes warrant(s) for improvements to State or federal highways, the developer shall be responsible for paying for those improvements. The site access into the Cerise Mine site is located along County Road 103 in a place that will allow for safe site distances. Lafarge will be responsible for improvements to the County Road 103 and Highway 82 intersection and all other improvements that, according to the traffic study, are required to accommodate the Cerise Mine. D. Adequate Capacity. Access serving the proposed use shall have the capacity to accept the additional traffic generated by the use safely and efficiently. The use shall not cause traffic congestion or unsafe traffic conditions, and all impacts to the County and state roadway system shall be mitigated through roadway improvements or impact fees, or both. The proposed access into the Cerise Mine has been designed with the appropriate radii and width to accommodate the truck traffic that will be generated on the site. The Traffic Study included with this application addresses the anticipated impacts to County Road 103 and Highway 82 and the improvements that are required to mitigate those impacts. Lafarge will work with the County regarding the need for impact fees due to traffic generated by the Cerise Mine. Section 7-109 No Significant Risk from Natural Hazards. The use is not subject to significant risk from natural hazards and will not exacerbate existing natural hazards. The proposed Cerise Mine is not subject to any significant risks from natural hazards nor will it exacerbate any existing natural hazards. Cerise Mine Major Impact Review Application Page 16 of 43 Section 7-201 Protection of Agricultural Lands. A. No Adverse Affect to Agricultural Operations. Land use changes on lands adjacent to or directly affecting agricultural operations shall not adversely affect, or otherwise limit the viability of existing agricultural operations. Proposed division and development of the land shall minimize the impacts of residential development on agricultural lands and agricultural operations, and maintain the opportunity for agricultural production on the most productive and viable parcels of land. The Cerise property is currently used for agricultural purposes (pastureland); however, as is their right per CRS 34-1-305(1), the Clifford Cerise Ranch Co, L.L.L.P. has decided that they would like to have their property mined for the gravel resource and then the land will be returned to agricultural use (pastureland). There are no other agricultural operations that will be adversely impacted by the Cerise Mine. B. Irrigation Ditches. 1. Maintenance. Where irrigation ditches cross or adjoin the land proposed to be developed, the developer shall insure that the use of those ditches, including maintenance, can continue uninterrupted. Some lateral ditches that cross the Cerise property will be removed as part of the mining process. However, those laterals do not convey water to other properties and therefore do not need to be maintained. The Basin Ditch which runs along the north edge of the mine site will not be impacted by the Cerise Mine. 2. Rights -of -Way. The land use change shall not interfere with the ditch rights-of-way. The Cerise Mine operations will all be south of the Basin Ditch. 3. Maintenance Easement. A maintenance easement of at least twenty-five (25) feet from the edges of the ditch banks shall be preserved and indicated on any final plat for subdivision, or the final development plan for any non -subdivision use. When approved in notarized written form by the ditch owner(s), that distance may be decreased. Not applicable; this is not an application to plat the property. Section 7-202 Protection of Wildlife Habitat Areas. The applicant shall consult with the Colorado Division of Wildlife or a qualified wildlife biologist in determining how best to avoid or mitigate impacts to wildlife habitat areas. Methods may include, but are not limited to, one or more of the following: A. Buffers. Visual and sound buffers shall be created through effective use of topography, vegetation, and similar measures to screen structures and activity areas from habitat areas. Mining activities will not occur in the Crystal Creek riparian corridor. In addition, there is a significant topographical difference between the Crystal Creek riparian corridor area and the portion of the Cerise property that will be mined. This topographical difference will work to buffer the mining activities from the habitat area. Cerise Mine Major Impact Review Application Page 17 of 43 B. Locational Controls of Land Disturbance. Land disturbance located so that wildlife is not forced to use new migration corridors, and is not exposed to significantly increased predation, interaction with vehicles, intense human activity, or more severe topography or climate. As explained in our Natural Habitat Statement found in Section 23 of the application, a biologist took a look at the site and determined that the Cerise Mine is proposed on land that is currently used for agricultural purposes and does not provide optimal wildlife habitat; therefore, any disturbance to wildlife will be minimal. C. Preservation of Native Vegetation. 1. Vegetation Utilized by Wildlife. Proposed land use changes are designed to preserve large areas of vegetation utilized by wildlife for food and cover, based upon recommendations by the Colorado Division of Wildlife. The vegetation used by wildlife is the native vegetation along Crystal Creek which is adjacent to the Cerise Mine but outside the area that will be impacted by mining (with the exception of a small area that will be impacted by the access that will cross Crystal Creek to get to County Road 103). 2. Removal and Replacement of Native Vegetation. When native vegetation must be removed within habitat areas, it is replaced with native and/ or desirable non-native vegetation capable of supporting post -disturbance land use. Native dryland grasses will be used to re -vegetate the area within the Crystal Creek Corridor that will be disturbed by the Cerise Mine. Please see the Landscape Plan in Section 13 of the application for details. 3. Removal of Noxious Weeds. Vegetation removed to control noxious weeds is not required to be replaced, unless the site requires revegetation to prevent other noxious weeds from becoming established. Noted D. Habitat Compensation. Where disturbance of critical wildlife habitat cannot be avoided, the developer may be required to acquire and permanently protect existing habitat to compensate for habitat that is lost to development. With the exception of the crossing of Crystal Creek for the access road, Lafarge will not have any activity in the riparian corridor. Section 7-203 Protection of Wetlands and Waterbodies. A. Restrictive Inner Buffer. 1. Minimum Setback. A setback of thirty-five (35) feet measured horizontally from the typical and ordinary high water on each side of a waterbody is required. With the exception of where the site access road will cross Crystal Creek, the Cerise Mine is over 35 feet away from the ordinary high water mark and wetlands associated with Crystal Creek. 2. Structures Permitted In Setback. Irrigation and water diversion facilities, flood control structures, culverts, bridges and other reasonable and necessary structures requiring some disturbance within this setback may be permitted. The access road is the only structure that will infringe into this area. Cerise Mine Major Impact Review Application Page 18 of 43 3. Structures and Activity Prohibited in Buffer Zone. Unless otherwise permitted or approved, the following activities and development shall be prohibited in the restrictive inner buffer zone include: a. Placement of material, including without limitation any soil, sand, gravel, mineral, aggregate, organic material, or snow plowed from roadways and parking areas. b. Construction, installation, or placement of any obstruction or the erection of a building or structure. c. Removal, excavation, or dredging of solid material, including without limitation any soil, sand, gravel, mineral, aggregate, or organic material. d. Removal of any existing live vegetation or conducting any activity which will cause any loss of vegetation, unless it involves the approved removal of noxious weeds, non-native species, dead or diseased trees. e. Lowering of the water level or water table by any means, including draining, ditching, trenching, impounding, pumping or comparable means. f. Disturbance of existing natural surface drainage characteristics, sedimentation patterns, flow patterns, or flood retention characteristics by any means including without limitation grading and alteration of existing topography. Measures taken to restore existing topography to improve drainage, flow patterns and flood control must be approved. Lafarge will obtain a Nationwide Permit to allow for the filling that will occur as a result of constructing the access road across Crystal Creek. Section 7-204 Protection of Water Quality from Pollutants. The following regulations shall apply to all land use changes, except agricultural activities allowed by right. A. Compliance with State and Federal Regulations. At a minimum, all hazardous materials shall be stored and used in compliance with applicable state and federal hazardous materials regulations. Lafarge will meet all applicable state and federal hazardous materials regulations. B. Storage Near Waterbodies Restricted. 1. The storage of hazardous materials within one hundred (100) horizontal feet of any waterbody is restricted. When no practical alternative exists, site specific best management practices shall be employed to minimize potential adverse water quality impacts. 2. Sand and salt for road traction shall not be stored within one hundred (100) horizontal feet of any waterbody unless there is no practicable alternative, in which case suitable site- specific best management practices shall be utilized. No hazardous materials will be stored by Lafarge within 100 feet of any waterbody. C. Spill Prevention. Measures shall be implemented to prevent spilled fuels, lubricants or other hazardous materials from entering a waterbody during construction or operation of equipment and/or facility. If a spill occurs it should be cleaned up immediately and disposed of properly. Included in Section 26 of the application is a copy of Lafarge's Spill Prevention Control and Countermeasure Plan (SPCC). Cerise Mine Major Impact Review Application Page 19 of 43 D. Machine Maintenance. Maintenance of vehicles or mobile machinery is prohibited within 100 feet of any waterbody. Emergency maintenance may be conducted until the vehicle or machinery can be moved. Lafarge will not perform any vehicle or equipment maintenance within 100 feet of any waterbody. E. Fuel storage Areas. Containment measures shall be provided for all fuel storage areas to prevent release into any waterbody. Inventory management or leak detection systems may be required. Containment measures for fuel storage tanks will be followed, as required. F. Waste Storage. Areas used for the collection and temporary storage of solid or liquid waste shall be designed to prevent discharge of these materials in runoff from the site. Collection sites shall be located away from the storm drainage system. Other best management practices such as covering the waste storage area, fencing the site, and constructing a perimeter dike to exclude runoff may also be required. There will be no waste collection sites on the Cerise Mine site. Section 7-205 Erosion and Sedimentation. The following requirements shall apply to land disturbances shall be subject to the Colorado Department of Health and Environment, National Pollutant Discharge Elimination System Permit and to all land development disturbing more than one-half (1/2) acre, with the exception of agricultural grading activities, unless excepted by CDPHE. Please see the Erosion and Sediment Control Plan in Section 12 of the application. Section 7-206 Drainage. A. Site Design to Facilitate Positive Drainage. Lots shall be laid out to provide positive drainage away from all buildings. The plant site has been graded to facilitate positive drainage. B. Coordination with Area Storm Drainage Pattern. Individual lot drainage shall be coordinated with the general storm drainage pattern for the area. 1. Drainage ditches shall have a minimum slope of no less than 0.75%. Energy dissipaters or retention ponds shall be installed in drainage ditches where flows are in excess of 5 feet/second. Ditches adjacent to roads shall have a maximum slope of 3:1 on the inside and outside edges, except where there is a cut slope on the outside edge where the edge of the ditch shall be matched to the cut slope. 2. Subdrains shall be required for all foundations where possible and shall divert away from building foundations and daylight to proper drainage channels. 3. Avoid Drainage to Adjacent Lots. Drainage shall be designed to avoid concentration of drainage from any lot to an adjacent lot. Not applicable for a mine site. Cerise Mine Major Impact Review Application Page 20 of 43 Section 7-207 Stormwater Run -Off. These standards shall apply to any new development within 100 feet of a waterbody, and to any other development creating 10,000 square feet or more of impervious surface area. These standards apply to the Cerise Mine. A. Avoid Direct Discharge to Streams or Other Waterbodies, Stormwater runoff from project areas likely to contain pollutants shall be managed in a manner that provides for at least one of the following and is sufficient to prevent water quality degradation, disturbance to adjoining property and degradation of public roads. 1. Runoff to Vegetated Areas. Direct runoff to stable, vegetated areas capable of maintaining sheetflow for infiltration. Vegetated receiving areas should be resistant to erosion from a design storm of 0.5 inches in 24 hours. The mining site will primarily be a gravel surface mainly void of vegetation during operation. Gravel swales will be constructed to direct runoff to the detention / tailings pond, however, the majority of flows are expected to infiltrate prior to reaching the pond. 2. On -Site Treatment. On-site treatment of storm water by use of best management practices designed to detain (see Section 7-207C, Detain and Treat Run-off below) or infiltrate the runoff and approved as part of the Stormwater Quality Control Plan prior to discharge to any natural waterbody. The stormwater runoff generated at the Cerise mine site will be directed to the detention/ tailings pond which will allow for the infiltration of the water. 3. Discharge to Stormwater Conveyance Structure. Discharge to a storm water conveyance structure, designed to accommodate the projected additional flows from the proposed project, with treatment by a regional or other storm water treatment facility prior to discharge into any natural waterbody. All project surface flows, including additional flows from the proposed project, will be directed to the detention/tailings pond which will allow for infiltration of the water. Discharge to Crystal Creek, the neighboring waterbody, is not needed as the pond will be large enough to capture and detain the flows. B. Minimize Directly -Connected Impervious Areas. The site design shall minimize the extent of directly -connected impervious area by including the following requirements. 1. Drainage Through Vegetated Pervious Buffer Strips. Runoff from developed impervious surfaces (rooftops, parking lots, sidewalks, etc.) shall drain over stable, vegetated pervious areas before reaching stormwater conveyance systems or discharging to water bodies. 2. Techniques Used in Conjunction with Buffer Strip. The requirement that all impervious areas drain to vegetated pervious buffer strips (paragraph B 1, above) may be reduced if the outflow from the vegetated pervious buffer strip is directed to other stormwater treatment methods. Examples of other potential techniques to be used in conjunction with vegetated pervious buffer strip are: infiltration devices, grass depressions, constructed wetlands, sand filters, dry ponds, etc. 3. Grass Buffer Strip Slope Design. When impervious surfaces drain onto grass buffer strips a slope of less than 10% is encouraged, unless an alternative design is approved by the County. This area will be used as a gravel mine and as such will not have many vegetated areas during Cerise Mine Major Impact Review Application Page 21 of 43 mining operations. Most of the surface will be gravel and as such will be pervious. Drainage swales will be constructed to direct runoff to the detention/tailings pond; however, the majority of surface runoff is expected to infiltrate through the porous gravel prior to reaching the detention facility. C. Detain and Treat Runoff. Permanent stormwater detention facilities are required to be designed to detain flows to historic peak discharge rates and to provide water quality benefits. Design criteria for detention facilities include: 1. Detention facilities shall ensure the post -development peak discharge rate does not exceed the pre -development peak discharge rate for the 2 -year and 25 -year return frequency, 24- hour duration storm. In determining runoff rates, the entire area contributing runoff shall be considered, including any existing off-site contribution. 2. To minimize the threat of major property damage or loss of life all permanent stormwater detention facilities must demonstrate that there is a safe passage of the 100 -year storm event without causing property damage. 3. Channels downstream from the stormwater detention pond discharge shall be protected from increased channel scour, bank instability, and erosion and sedimentation from the 25 -year return frequency, 24-hour design storm. 4. Removal of pollutants shall be accomplished by sizing dry detention basins to incorporate a 40 -hour emptying time for a design precipitation event of 0.5 inches in 24 hours, with no more than fifty percent (50%) of the water being released in twelve (12) hours. If retention ponds ("wet ponds") are used, a 24-hour emptying time is required. For drainage from parking lots, vehicle maintenance facilities, or other areas with extensive vehicular use, a sand and oil grease trap or similar measures also may be required. To promote pollutant removal, detention basins length -to -width ratio should be not less than 2, with a ratio of 4 recommended where site constraints allow. A sedimentation "forebay" is recommended to promote long-term functioning of the structure. Access to both the forebay and pond by maintenance equipment is required. 5. Culverts, drainage pipes and bridges shall be designed and constructed in compliance with AASHTO recommendations for a water live load. 6. A written inspection and maintenance agreement shall be required to ensure regular inspection and maintenance of on-site detention facilities. The detention/tailings pond located on the southwest corner of the site will be used to completely detain the surface runoff and allow the water to infiltrate. Volume will be accounted for up to and including the 100 year event. Section 7-208 Air Quality. The land use change shall not cause air quality to be reduced below acceptable levels established by the Colorado Air Pollution Control Division. The Cerise Mine will not cause air quality to be reduced below acceptable levels established by the Colorado Air Pollution Control Division. For more information regarding air quality, please see Section 20 which includes an Air Quality Statement, copies of air permits for the equipment proposed for the site, and a letter from Buys and Associates explaining how the site will meet air quality standards. Cerise Mine Major Impact Review Application Page 22 of 43 Section 7-209 Areas Subject to Wildfire Hazards. The following standards shall apply to land use changes in Areas Subject to Wildfire Hazards, as identified on the County Wildfire Hazards Map. Wildfires is not a concern for the Cerise Mine site. Section 7-210 Areas Subject to Natural Hazards and Geologic Hazards. The development shall be designed to eliminate or mitigate the potential effects of hazardous site conditions, by a qualified professional geotechnical engineer. There are no natural hazard or geologic hazards to eliminate or mitigate nor will the mining activities create any hazards. Please see Stability Analysis letter prepared by Tetra Tech in Section 17 of the application for more details. Section 7-211 Areas with Archeological, Paleontological or Historical Importance. The proposed land use change shall be designed to avoid or mitigate negative impacts upon previously identified archeological, paleontological and historical resources that exist in areas to be affected by the proposed development. There are no previously identified archeological, paleontological or historical resources on the site according to the report prepared by Grand River Institute for the Cerise Mine property (see Section 18 of the application for a copy of the report). Section 7-212 Reclamation A. Applicability. These standards shall apply to any activity that requires review and permit approval by the County, and to the following activities. 1. Installation of ISDS. Installation of a new or replacement individual sewage disposal system (ISDS) that is required to obtain an Individual Sewage Disposal System Permit. 2. Driveway Construction. Any driveway construction that requires a Garfield County Access Permit or a Colorado Department of Transportation Access Permit. An ISDS system will be installed and a new driveway will be constructed; therefore, the reclamation standards, below, apply to the Cerise Mine. B. Reclamation of Disturbed Areas. Areas disturbed during development shall be restored as natural -appearing landforms that blend in with adjacent undisturbed topography. (Reso 2009- 53) Following mining, the Cerise Mine site is proposed to be reclaimed with vegetation that is consistent with the vegetation that currently grows on the property (please see the Landscape Plan for details). In addition, the land above the ISDS system and the land disturbed by the construction of the access road will be revegetated following their installation/construction. 1. Contouring and Revegetation. Abrupt angular transitions and linear placement on visible slopes shall be avoided. Areas disturbed by grading shall be contoured so they can be re - vegetated, and shall be planted and shall have vegetation established and growing based on 70% coverage as compared with the original on-site vegetation within two (2) growing seasons, using species with a diversity of native and/or desirable non-native vegetation capable of supporting the post -disturbance land use. a. Revegetation of Disturbed Areas. To the maximum extent feasible, disturbed areas Cerise Mine Major Impact Review Application Page 23 of 43 shall be revegetated to a desired plant community with composition of weed -free species and plant cover typical to that site. Noted; please see the Landscape Plan in Section 13 of the application. 2. Application of Top Soil. Top soil shall be stockpiled and placed on disturbed areas. All topsoil will be scraped prior to mining and stockpiled for placement back on the property following mining operations. 3. Time Line Plan. Every area disturbed shall have a time line approved for the reclamation of the site approved by the County. As much as possible, the Cerise Mine site will be concurrently mined and reclaimed. Final reclamation of the entire site will be completed within two (2) years of the completion of mining. Section 7- 814 Additional Standards Applicable to Mining and Extraction Uses. A. Roads. 1. Impact Mitigation. The mining operator or owner shall bear the proportionate cost of all road and bridge improvements, repairs, and maintenance necessitated by the proposed mining operation. Lafarge understands this requirement and it is their understanding that the details of this will be addressed in the improvements agreement. 2. Vehicle Weight. The weight of trucks shall not exceed federal, state or local government imposed road or bridge weight capacity on approved haulage routes, as those routes are established by the procedures in the Garfield County Overweight Vehicle Regulations. The Cerise Mine will comply with the Garfield County Overweight Vehicle Regulations. 3. Seasonal Traffic Limitation. As a condition of approval, the County may impose limits on the number of trucks that may access the mine to avoid damage to roads caused by heavy vehicle use, weather conditions or water saturation. The number of trucks proposed to access the Cerise Mine is addressed in the traffic study (Section 22 of the application). Lafarge will work with the County, if and as needed, to limit truck access to prevent road damage. B. Routing. Designation of construction and haul routes for a specific mining operation application shall comply with the following standards: 1. Avoidance of Developed Areas. Truck haulage and traffic routes shall be designed to the maximum extent feasible to avoid residential areas, commercial areas, environmentally and visually sensitive areas, schools and other civic buildings, municipalities and already congested locations. Alternative routes shall be identified. Access to the Cerise Mine will be off County Road 103, south of any access to residential streets or driveways. To get to County Road 103, the access road will need to cross Crystal Creek. Therefore, the access is proposed in a location that will provide adequate site distance along County Road 103 and minimize impacts to the riparian corridor along the Creek. Once on County Road 103, the trucks will primarily turn south to Highway 82 where they will turn east or west onto the highway depending on their destination. There may be a few instances where trucks will turn north on County Road 103, but this would only be if product is needed for construction on a property north of the Cerise Mine site. In addition, Cerise Mine Major Impact Review Application Page 24 of 43 when the Cerise Mine is operating, Lafarge will no longer be mining product out of the adjacent Powers Mine Site. This means that the traffic along Highway 82 that is associated with Lafarge mining will move east a few hundred feet. Having the trucks use County Road 103 rather than a separate curb cut onto Highway 82 will improve safety along the highway. Therefore, as much as possible, the haul route avoids residential areas, commercial areas, environmentally and visually sensitive areas, schools and other civic buildings, municipalities and already congested locations. 2. Timing of Hauling. Timing of truck traffic may be controlled to prevent congestion or adverse noise impacts or safety risks. According to the traffic study prepared for the Cerise Mine site (provided in Section 22), the mine site isn 't projected to create any congestion or safety risks and the Noise Analysis (provided in Section 21) doesn't any noise impact issues from truck traffic. Therefore, there shouldn't be a need to control the timing of truck traffic. However, should a problem develop, Lafarge is willing to work with the County to resolve the issue. 3. Load Control. Applicant shall prevent loss of loads and fugitive dust emissions during transit, and shall be responsible to ensure that haul routes are maintained in accordance with dust -suppressant methods required by applicable state or federal agency. During transit, all loads leaving the site will be watered or covered as necessary to suppress dust. The haul route for the trucks is paved so dust will not be generated as they travel the route. C. Wildlife. Mining operations shall mitigate any impacts not be located in wildlife habitat areas as identified by the Colorado Division of Wildlife. Crystal Creek runs along the edge of the Cerise Mine site. No mining activities will occur in the Crystal Creek riparian corridor. The portion of the Cerise property that will be mined has been farmed for many years and therefore does not currently provide optimal wildlife habitat. For more information on wildlife, please see the Natural Habitat Statement in Section 23 of the application. D. Emergency Preparedness. The site operator prepare an emergency preparedness plan and have it on site and provided to the appropriate emergency providers for the site. Prior to operations, Lafarge will prepare an emergency preparedness plan, have it on-site and provide it to emergency service providers. Section 7-840 Additional Standards Applicable to Gravel Extraction A. Water Quantity & Quality Impacts / Floodplain Impacts If a gravel pit is located within the floodplain there is a reasonable chance that it could be flooded during its operational life. Equipment, machinery, fuel etc could become pollutant sources in the case of a flood. In addition, if the pit is located near the floodway of a river there is the possibility that in a flood a gravel pit could alter the natural course of a river. This can have negative impacts on a river ecosystem and unknown impacts on nearby landowners. Every Application for gravel extraction shall address the following: 1. When the proposal is near a river or stream the Applicant is required to submit an analysis by a professional engineer showing the boundaries of the floodplain and the floodway in the Cerise Mine Major Impact Review Application Page 25 of 43 area of the pit. The Cerise Mine site is located outside of the floodplain and floodway of the Roaring Fork River. The mine site is separate from the river and floodplain by both Highway 82 and a ridge that is over 100 feet higher than the Roaring Fork River Base Flood Elevation (BFE) based on the FEMA Flood Insurance Rate Mate for Garfield County, CO (unincorporated areas) Community Panel 080205 1880B. Crystal Creek is a smaller stream that runs along the western border of the mining site. This creek is not included in the FEMA mapping for the area. However, the river is over 25 feet lower than any adjacent mining activity and over 60 feet from the closest grading extents. There will be no mining in the floodplain of the creek, which has a 100 year discharge of approximately 300 cfs. 2. Provide a Stormwater Management Plan that demonstrates how the project will not adversely affect surface or groundwater resources. Additionally, provide a Sediment and Erosion Control plan that demonstrates what best management practices will be used in the project. Included in this Major Impact Review application is an Erosion Control Plan (provided in Section 12) that demonstrates what best management practices will be used on the site. A draft Stormwater Management Plan (SWMP) is also provided in Section 12 of the application. The SWMP will be finalized upon approval of the mining plan by the County and Division of Reclamation, Mining and Safety. According to Colorado Regulations, a SWMP is required in order to apply for a Colorado Discharge Permit System (CDPS) stormwater only permit, which is required prior to site disturbance. The CDPS permit will strictly be for stormwater and will be covered under a COR34-0000 permit (see Section 26 for a copy of the permit). 3. In all cases, an application for a gravel mining operation shall include a Spill Prevention Counter Measure and Control Plan (SPCC) that provides a program that handles spills of hazardous materials as well as local contact information for responsible personnel at the facility. A copy of the SPCC is provided in Section 27 of the application. 4. No land use change application shall be accepted by the County without a letter from the applicable fire protection district stating that the proposed project has been adequately designed to handle the storage of flammable or explosive solids or gases and that the methods comply with the national, state and local fire codes. Included in Section 19 of our application package is a letter to the Carbondale Fire Protection District identifying the flammable or explosive solids, liquids and gases that Lafarge may have on site and the steps that they will take to comply with the national, state and local fire codes. We have also attached the letter received from the Fire District in response to our letter indicating that the District found Cerise Mine proposal to be acceptable. 5. No materials or wastes shall be deposited upon a property in such form or manner that they may be transferred off the property by any reasonably foreseeable natural causes or forces. No materials or wastes will be deposited on the property that can be transferred off the property by a reasonably foreseeable natural cause or force. Cerise Mine Major Impact Review Application Page 26 of 43 6. Development in 100 year Floodplain: Floodways - located within areas of special flood hazard established in as found in the report entitled the Flood Insurance Study, Garfield County, Colorado, Unincorporated Areas dated August 2, 2006 and the accompanying flood maps entitled Flood Boundary Maps, Floodway Maps and Flood Insurance Rate Maps, Garfield County, Colorado, Unincorporated Areas, as the same may be from time to time amended through the Zone District Amendment procedure in Article IV are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles and erosion potential, the following provisions shall apply: a. Encroachments are prohibited, including fill, new construction, substantial improvements and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase or decrease in flood levels within the County during the occurrence of the base flood discharge. b. All new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of Section 7-701(G) and Section 7-701(H). c. Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Regulations, the County may permit encroachments within the adopted regulatory floodway that would result in an increase in base flood elevations, provided that the Applicant obtains a Letter of Map Revision (LOMR) for a floodway revision through FEMA and that no mining activity shall occur until FEMA has approved a Letter of Map Revision (LOMR). d. In all cases, there shall be no storage of fuel or hazardous materials including concrete / asphalt batch plants within the floodway. The entire mining site is located outside of any designated floodway; therefore, there will be no storage of fuel or hazardous materials in the floodway. See Section 7-840, response A.1 for further information regarding floodplain. 7. Standards for Areas of Shallow Flooding: Located within the areas of special flood hazard which are areas designated as shallow flooding also known as the flood -fringe as found in the report entitled the Flood Insurance Study, Garfield County, Colorado, Unincorporated Areas dated August 2, 2006 and the accompanying flood maps entitled Flood Boundary Maps, Floodway Maps and Flood Insurance Rate Maps, Garfield County, Colorado, Unincorporated Areas, as the same may be from time to time amended through the Zone District Amendment procedure in Article IV. These areas have special flood hazards associated with base flood depths of 1 to 3 feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow; therefore, the following provisions apply: a. All new construction and substantial improvements of residential structures have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified). b. All new construction and substantial improvements of non-residential structures; Cerise Mine Major Impact Review Application Page 27 of 43 i. have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified), or; ii. together with attendant utility and sanitary facilities be designed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads of effects of buoyancy. c. A registered professional engineer shall submit a certification to the County Floodplain Administrator that the standards of this Section have been fully satisfied. d. Require within Zones AH or AO adequate drainage paths around structures on slopes, to guide flood waters around and away from proposed structures. This standard does not apply as the area being permitted is not within an area of shallow flooding. 8. The proposed operation will be located a sufficient distance from other mining operations so as not to create cumulative impacts to the integrity of the water course. The Board of Commissioners will determine sufficiency of distance. This mining site is not located within the 100 year floodplain of the Roaring Fork River or Crystal Creek; therefore, it has an extremely rare chance of impacting the integrity of either water course. Unlike most gravel mine sites, the Cerise site is situated on a plateau high above the adjacent waterways. Mining operations will be conducted in such a manner that the site will eventually become a large basin that is topographically isolated from any surrounding areas. 9. In -stream mining is not permitted. No in -stream mining is proposed. 10. All applications shall provide a de -water / discharge plan that provides a detailed graphic representation of how dewatering operations shall occur. This plan shall demonstrate that the discharge will not exceed state standards for discharge into a watercourse or wetland. There is no need for a discharge point with this application. Due to the fact that all mining will be above groundwater, de -watering will not be required as part of the mining process and all storm water will infiltrate or be directed to the drainage/tailings pond. 11. In all cases, the Application shall contain proof that the operation has adequate legal and physical water for the proposed application. Lafarge will lease water from Basalt Water Conservancy District to supply their operations at the Cerise Mine. Documentation from Basalt Water Conservancy District indicating that the District's Board approved Lafarge's request to lease water is provided in Section 16 of the application. B. Air Quality Fugitive dust from disturbed areas is one of the primary causes of gravel pit air pollution. The potential for soil erosion potential also increases proportionate to the amount of disturbed area. Gravel Pits should make an active effort to reduce disturbed area through phased reclamation, efficient operations, and landscaping. Disturbed acreage can also provide a measure of visual impact when the operation is located on valley floor and there are residences on nearby hillsides. Opacity shall not exceed 20%. Lafarge will operate the Cerise Mine site in a manner that controls fugitive dust. Please see the Cerise Mine Major Impact Review Application Page 28 of 43 response below and the Air Quality Statement, copies of air permits, and letter from Buys and Associates included in Section 20 of the application for more information. 1. All gravel operations in the County shall comply with applicable County, State, and Federal regulations regulating air pollution and shall not be conducted in a manner constituting a public nuisance or hazard. The Cerise Mine will operate in a manner that complies with applicable air pollution regulations. For more detail, please see the Air Quality Statement and letter from Buys and Associates provided in Section 20 of the application. 2. Impacts on adjacent land from the generation of vapor, dust, smoke, or other emanations. All applications shall demonstrate how they will meet County, State, and Federal air pollution regulations. Any repair and maintenance activity requiring the use of equipment that will generate odors beyond the property boundaries will be conducted within a building at any time or outdoors during the hours of 7:00 AM to 8:00 PM, Monday - Saturday. The Cerise Mine will only conduct repair and maintenance activities that require the use of equipment that generates odors beyond the permit boundary between 7:00 am and 8:00 pm, Monday through Saturday. 3. The proposed operation will be located a sufficient distance from other mining operations so as not to create cumulative impacts to air quality. Western Slope Aggregate's Blue Pit Mine, to the east of the Cerise Mine, has been approved to expand its operations. According to information presented at the public hearings for the Blue Pit expansion, and based on the projected timing of the Cerise Mine and the Blue Pit mining activities, there will be about a two year time frame when the mining activity in the Blue Pit (Area 4, Phase 2) will be immediately adjacent to the Cerise Mine (please see the Cumulative Impact Analysis Site Plan graphics found in Section 15 of the application for a graphic illustration of this). However, this will not lead to cumulative air quality impacts. The Colorado Department of Public Health and Environment (CDPHE) is the agency that issues air quality permits and their permit process requires all mines to meet National Ambient Air Quality Standards (NAAQS) which take into consideration the impacts of the mining project and background concentrations of pollutants. In addition, the NAAQS require the mining operations to meet air quality standards at their property line. This means that when it comes to air quality, it doesn't matter if the Cerise Mine and Blue Pit are right next to each other or a mile apart. In order to be in compliance with the NAAQS, the CDPHE will require both the Blue Pit and Cerise Mine to operate in a manner that prevents air quality from exceeding the NAAQS limits at each mine's property line. In order to ensure compliance, CDPHE may impose emission restrictions and/or require emission controls for the facilities. In addition, they may require dispersion modeling to demonstrate compliance with the NAAQS. Lafarge understands this may be required by CDPHE and they will comply. Therefore, NAAQS will prevent cumulative air quality impacts. In addition, Lafarge already has a fugitive dust control plan which they will follow during operations at the Cerise Mine to keep air quality in compliance with the NAAQS. This plan is as follows: • Exposed areas will be vegetated or stabilized to limit wind erosion and to provide screening. Cerise Mine Major Impact Review Application Page 29 of 43 • When necessary, a water truck will spray the gravel as it is removed and transported. • Water spray bars will be installed, operated and maintained in the conveyor system and crushing and screening plant. • Drop heights of gravel will be limited for conveyor loading, transfer points, and screening and crushing activities. • On-site vehicle speeds will be limited. • Frequently traveled on-site roadways will be sprayed with water to minimize re - entrainment of dust from the surface of the road. • Dust from loaded haul trucks will be limited by covering or watering as necessary. • A minimum 50 foot setback around the Cerise property will be maintained to allow any fugitive dust to settle before being carried by wind. • Emission controls and limits as required by CDPHE will be enforced and followed. • Berms and mine walls will be constructed to serve as wind breaks. • Reclamation including complete revegetation of the site, once mining has been completed, to the Colorado Division of Reclamation, Mining and Safety standards. 4. No application shall be approved until the Applicant submits evidence that all plants and processing equipment shall have current Colorado Department of Public Health and the Environment (CDPHE) Air Pollution Permits and shall meet current CDPHE emissions standards for air and water. Copies of the air permits for all plants and processing equipment to be used on the site are provided in Section 20 of the application. C. Noise / Vibration All gravel extraction operations in the County shall comply with applicable County, State, and Federal regulations regulating noise pollution and shall not be conducted in a manner constituting a public nuisance or hazard. Volume of sound generated shall comply with the standards set forth in the Colorado Revised Statutes at the time any new application is made. A detailed Noise Analysis report was prepared by Hankard Environmental for the Cerise Mine. The Cerise Mine will comply with applicable County, State and Federal noise pollution regulations and will conduct their operations in a manner that will not generate a public nuisance or hazard. Please see the Noise Analysis report in Section 21 of the application for details. 1. An Applicant shall submit a noise study that demonstrates the proposed gravel operation can meet the requirements in the matrix below based on measuring the sound levels of noise radiating from a property line at a distance of 25 feet or more beyond the subject property. (The image to the right shows a dashed line at 25 feet beyond the subject property where noise shall be measured.) A Noise Analysis for the Cerise Mine was prepared by Hankard Environmental, an acoustics and vibration consulting firm, and is provided in Section 21 of the application. 2. Note, the dB(A) threshold shown below shall be that of the receiver and not that of the emitter. For example, while the gravel operation would be considered an industrial operation, the dB(A) levels shown below are measured according to the neighboring uses so that if a residential use was located adjacent to the operation, sound levels could not exceed 55 dB(A) from 7 AM to 7 PM and 50 dB(A) from 7 PM to 7 AM. Cerise Mine Major Impact Review Application Page 30 of 43 Zone 7 am to 7 pm 7 pm to 7 am Residential 55 dB(A) 50 dB(A) Commercial 60 dB(A) 55 dB(A) Light Industrial 65 dB(A) 70 dB(A) Industrial 80 dB(A) 75 dB(A) The dB(A) threshold of the receivers will not exceed the thresholds identified in the table above. This threshold standard is addressed in the Noise Analysis report. 3. Every use shall be so operated that the ground vibration inherently and recurrently generated is not perceptible, without instruments, at any point of any boundary line of the property on which the use is located. Lafarge will not conduct any activities within the Cerise Mine permit boundary that causes perceptible ground vibration at any point along the boundary line of the Cerise property. D. Visual Impacts All applications for gravel extraction shall address the following: 1. All gravel operations proposed to mine areas greater than 30 acres shall be designed in multiple phases in order to minimize the visual impact of the gravel pit primarily by logical "sequencing" and "overall layout" of the pit's design. Cerise Mine will be mined in five phases (1, 2, 3, 4A and 4B) which range in size from 2.1 to 24.1 acres as shown on the Site Plan map found in Section 11 of the application. 2. Design of the proposed use including the storage of heavy equipment is organized to minimize impact on adjacent uses of land through installation of screen fences, berming, and/ or landscape materials on the periphery of the lot and by location of intensively utilized areas, access points, lighting and signs in such a manner as to protect established neighborhood character. Due to the topography of the property, the mining activities on the site will be hard to see from Highway 82 and other areas south of the property. However, land north of the Cerise Mine is at a higher elevation and looks down on the property. Therefore, Lafarge is taking steps to minimize the visual impact for those neighbors. Early in the process, topsoil and overburden stockpiles will be placed on the west and north edges of the permit boundary. These stockpiles will be re -vegetated and serve as berms to help screen views into the mine site from the north. In addition, to further minimize the visual impact of the mining activities, Lafarge will be moving the aggregate processing plant equipment onto the floor of the mine as soon as Phase 2 mining is completed. The access point into the site has been located along County Road 103 away from any residential streets or driveways so that trucks coming and going from the site to Highway 82 will not pass any homes. Lighting will be kept to a minimum. All on-site lighting will be downcast and shielded so as to not shine directly onto any other property. An unobtrusive site identification sign will be placed at the entrance to the facility. A View Study model was prepared to help all parties involved understand the effectiveness of the proposed screening and berming. Several screen shots from that study are provided Cerise Mine Major Impact Review Application Page 31 of 43 in Section 15 of the application. The View Study model is an interactive tool that we can show the County staff Planning Commission, County Commissioners and neighbors in a meeting setting. With the model, we have the ability to look at the site from the vantage point of properties all the way around the Cerise Mine site. 3. At the discretion of the County Commissioners, all outdoor storage facilities may be required to be enclosed by fence, landscaping or wall adequate to conceal such facilities from adjacent property. Re -vegetated topsoil and overburden stockpiles that will serve as berms for the life of the mine, as well as existing vegetation along Crystal Creek, will help to screen the plant site structures and activity from adjacent properties. 4. New long-term (more than one year) mining operations will minimize visual impacts along entryways to growth centers. Planning Commission and/or the Board of County Commissioners will determine sufficiency of minimization. Not applicable; the Cerise Mine is not located in a growth center entryway. 5. All applications shall include a `Germing, Screening, and Buffering Plan" to aid in visual screening. Provisions in this plan shall be in place prior to commercial mining The Applicant shall invite the Staff from the County Building and Planning Department to the site to inspect that the installation occurred pursuant to the plan presented to the Board of County Commissioners prior to the commencement of any commercial activity and issuance of a land use change permit. A Berming, Screening and Buffering Plan is provided in Section 15 of the application. The Plan calls out the mature vegetation along Crystal Creek which runs along the west edge of the Cerise Mine site which will serve as an effective buffer. It also points out the significant grade change (approximately 90 feet) from Highway 82 up to the top of the plateau Cerise property where Lafarge will be mining. This difference in topography will effectively screen views from the south. In addition, the topsoil and overburden stockpiles that will be created on the north and west edges of the permit boundary area are called out on the Plan. These stockpiles will be in place prior to mining. They will be re -vegetated by Lafarge and remain in place as berms for the life of the mine. These berms will help screen the mining and plant operations occurring on the property. There are neighbors that are located north and above the Cerise Mine site in Wooden Deer Subdivision. It is not possible to screen all views of the Cerise Mine site from the neighboring homes because they are at a higher elevation than the mine; however, Lafarge is committed to doing what they can to address visual impact concerns. This is why Lafarge hired a consultant to construct an accurate visual impact model of the Cerise Mine site in relation to the surrounding properties. The model gives all parties involved a realistic understanding of the visual impact associated with the mine. The visual impact model is computerized and the user can move around the model and look at the Cerise Mine from any vantage point. For a base, model uses the 2' topographic contours that were obtained by Lafarge for the Cerise Mine site in conjunction with USGS topography for the areas around the site. The model then pulls in the proposed topographic features (mining cells as well as overburden and topsoil stockpiles) of the Cerise Mine per the proposed mining and reclamation plans. Existing and proposed vegetation is also built into the model (existing trees shown in the model were horizontally located based on information pulled from Cerise Mine Major Impact Review Application Page 32 of 43 Google Earth aerial mapping). Using the model, we have the ability to navigate to individual neighbors' properties or public streets and look at the Cerise Mine to get a realistic view of what they will see. Based on the results of the model, as expected, the entire operation is not completely screened from view; however, the proposed buffering and screening associated with the project is effective. Screen shots from the model are provided in Section 15 of the application. It is understood that Lafarge will need to invite County Staff to the site to inspect the installation of the stockpiles/berms identified on the Berming, Screening and Buffering Plan map (found in Section 15) prior to the start of mining. 6. All lighting shall be the minimum necessary, directed inward and downward towards the property. Lighting will be kept to a minimum. All on-site lighting will be downcast and shielded so as to not shine directly onto any other property. No flashing lights will be used and lights will not exceed 40 feet in height. There will be some lighting available on-site for use during operations, if needed, and the entrances to structures will also be lit at night for security purposes. 7. Unless otherwise determined by the Board of County Commissioners, mining operations shall be allowed to progress so long as the previous pit has been reclaimed within 6 months after the commencement of the new pit mining operation. If the reclamation has not commenced in six months or has been completed within eighteen (18) months, all mining operations on the property shall stop until the reclamation / revegetation has occurred to the satisfaction of the County. Completion, including but not limited to top -soiling, seeding, mulching, sapling planting, and water filling of the lake, shall be determined by the provisions contained within the reclamation plan approved by the Board of County Commissioners. The Cerise Mine is proposed to be concurrently mined and reclaimed as described on the Site Plan map. E. Impacts to County Road System 1. All applications for a gravel extraction operation shall submit a traffic impact study prepared by a professional traffic engineer that identifies projected volumes of traffic through the life of the project, expected haul routes and any improvements street improvements adequate to accommodate traffic volume generated by the proposed use and to provide safe, convenient access to the use. These improvements shall either be in place or shall be constructed in conjunction with the proposed use. In accordance with this requirement, a detailed Traffic Impact Study was submitted to the County (see Section 22 of the application). All traffic associated with the Cerise Mine site will use an access onto County Road 103 and almost always come and go on County Road 103 to and from State Highway 82. The only reason trucks would turn north on County Road 103 would be if there was a local construction project north of the Cerise Mine that needed to have aggregates, concrete or asphalt delivered. According to the Traffic Impact Study, current operating conditions are acceptable in the area of the Cerise site and all projected trips associated with the Cerise Mine can easily be managed by County Road 103 and State Highway 82 with the following improvements: Cerise Mine Major Impact Review Application Page 33 of 43 • All auxiliary lanes warranted by current and future traffic, including traffic generated by Cerise Mine, currently exist on Highway 82 at the intersection of County Road 103. However, the west bound right turn deceleration lane on Highway 82 for vehicles turning right/north on County Road 103 and the east bound left turn acceleration lane for vehicles turning left/east onto State Highway 82 from County Road 103 are substandard based on current CDOT Access Code criteria. Therefore, these two lanes will need to be improved to meet current design standards. All turn lanes on Highway 82 that are west of County Road 103 are acceptable in their current form. Striping changes to compliment the intersection improvements will also be made. • Turning radii on the east side of the Highway 82 and County Road 103 intersection will be increased to be capable of serving a WB-67 design vehicle. • Truck warning signs need to be installed on the County Road 103 approaches to the site access and a stop sign will be needed on the access approach to County Road 103. The Traffic Impact Study concludes that with these improvements in place, acceptable levels of service will be achieved and maintained through the long-term for all traffic movements at all intersections. Therefore, Lafarge will make each of these improvements prior to mining the Cerise site. 2. Truck traffic will not access the mining operation through residential or commercial areas, or such traffic will be mitigated. Truck traffic will not access the mining operation through residential or commercial areas. 3. The Applicant shall submit evidence of insurance for a minimum of $1,000,000 to cover any damages to public and private property, and Garfield County shall be named as an additional insured. If the applicant demonstrates its operation will not require a Garfield County access permit, this insurance shall not be required. (Resolution 2009-88). Evidence of insurance will be provided prior to final approval of the Major Impact Review application. 4. Expected haul routes from the mine will be upgraded to withstand the additional traffic, if determined by the traffic study or recommendation by the County Engineer, and the permittee will prevent road damage and mitigate dust, under the supervision of the Road and Bridge Director. (Resolution 2009-88) Improvements to the haul route (County Road 103 to Highway 82) will be made as identified in the Traffic Study or at the recommendation of the County Engineer. Lafarge will take steps to prevent road damage and mitigate dust and will be responsible for damage to the road caused by trucks from the Cerise Mine site. 5. The Applicant shall obtain driveway access permit/s issued by Garfield County Road & Bridge Department at specific locations to be approved by the Road and Bridge Department. These permits shall have conditions specific to the driveway/s. This may include stop sign/s at entrance to County Road. The stop signs and installation shall be as required in the MUTCD (Manual on Uniform Traffic Control Devices). Paved or concrete aprons shall also be required as specified by the issued permit/s. Lafarge will coordinate with the Garfield County Road & Bridge Department to obtain a driveway access permit onto County Road 103. A stop sign for vehicles leaving the site will Cerise Mine Major Impact Review Application Page 34 of 43 be provided at the intersection of the driveway and County Road 103. The driveway connection into the site and the plant site area are proposed to be paved. Please see the plant site detail on page 12 of the Site Plan (Section 11 of the application). 6. If road damage on a County Road becomes evident due to the traffic generated from the gravel pit operation, the Road and Bridge Department shall require that repair or replacement of the road surface as determined by Garfield County Road & Bridge Department become the responsibility of the owners or operators of the gravel pit operation. Lafarge understands that they are responsible for repairing damage to roads caused by traffic generated by the Cerise Mine site. F. Impacts to Wildlife 1. The Applicant shall demonstrate the presence or absence of Threatened and Endangered species as well as the presence or absence of critical habitats for Threatened and Endangered species. There are no Threatened or Endangered species or habitat within the permit boundary of the Cerise Mine. Please see the attached Natural Habitat Statement prepared by Buys and Associates in Section 23 of the application. 2. The Application shall contain a Wildlife Impact Analysis prepared by a professional that identifies existing wildlife habitat and impacts on wildlife as a result of the project which may include but be not limited to impacts to domestic animals through the creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions. The required Natural Habitat Statement is provided in Section 23 of the application. G. Compatibility with Surrounding Land Uses The following regulations shall apply to all gravel operations in the County: 1. No permit shall be approved unless sufficient distances separate such use from abutting property which might otherwise be damaged by operations of the proposed use(s). Attached please find a copy of a Stability Analysis report prepared by Tetra Tech as part of the application to the Division of Reclamation, Mining, and Safety (see Section 17). The report indicates that the proposed mining will not damage any structures on abutting properties. 2. The equipment storage area is not placed any closer than 300 ft. from any existing residential dwelling. All equipment storage is more than 300 feet away from any existing residential dwellings. 3. Loading and unloading of vehicles shall be conducted on private property and may not be conducted on any public right-of-way. All loading and unloading of vehicles will occur on the Cerise Mine site and not in public right-of-way. 4. Any storage area for uses not associated with natural resources, shall not exceed ten (10) acres in size. Other than the overburden, topsoil and aggregate stockpiles there are no storage areas over 10 acres in size. 5. Any lighting of storage area shall be pointed downward and inward to the property center and shaded to prevent direct reflection on adjacent property. Cerise Mine Major Impact Review Application Page 35 of 43 Storage areas will not be regularly lit and if they are lit, it will only be during the hours of operation and the lighting will be downcast and shielded so as to not shine directly onto any other property. 6. Shall be compatible with surrounding agricultural, residential, and recreational land uses by selection of location and/or mitigation. The property to the west of the Cerise Mine is currently being mined by Lafarge (Powers Pit). Land to the east of the Cerise Mine site is currently agricultural; however, Western Slope Aggregates has plans to expand the Blue Pit onto this property. Therefore, compatibility to the west and east of the Cerise Mine is not an issue. The property to the south of the Cerise Mine is significantly lower in elevation and so it will be difficult to view the mining activities on the Cerise property from the south. There are residential properties to the north of the Cerise Site which are at a higher elevation than the Cerise Mine. Therefore, steps are being taken to mitigate impacts on that area to address compatibility issues. Large, vegetated berms will be created on the north side of the site to screen and buffer the site from residential uses to the north. In addition, Lafarge will be moving their aggregate processing plant and the temporary asphalt plant site into the bottom of the mining cell following Phase 2 mining. Placing these operations down in a hole will further help to minimize the impact of these operations on the residential area. The access location to the mine site was also carefully chosen with the residential neighbors in mind. Currently, the access to the property is on the north off of County Road 104. While continuing to use this site access would have been the easiest way for Lafarge to access the site, it would have impacted residences to the north. Therefore, Lafarge is proposing to construct a new access out to County Road 103. The access is south of any residential roads or driveways onto County Road 103 so that the trucks will not pass by existing homes as they drive south to Highway 82. The site will also comply with the County's noise impact and air quality regulations (see Sections 20 and 21 of the application for more details). In Section 15 of the application, we have provided Cumulative Impact Analysis Site Plan graphics and View Study graphics to further help understand how the Cerise Mine will be compatible with the surrounding land uses. 7. The proposed operation will be located a sufficient distance from other mining operations so as not to create non-mitigatable cumulative impacts to roads, air and water quality, or other resources and amenities. The location of aggregate mining operations is driven by the location of the aggregate resource. As a result, the proposed Cerise Mine is located in an area where there is other aggregate mining occurring. However, permitting the Cerise Mine will not create a non- mitigatable cumulative impact to roads, air and water quality or other resources and amenities for the following reasons: • One of the adjacent mines is Lafarge's existing Powers Mine which is directly east of the Cerise Mine site. Prior to commencing mining operations at the Cerise site, Lafarge will complete mining at the Powers site and be in the reclamation stage. • Western Slope Aggregates currently operates the Blue Pit on the Blue property which is located east of the Cerise Mine site. They were recently approved to amend their permit to allow for the expansion of their mine site to the west. It is our understanding that the resource in their currently permitted area will be depleted in Cerise Mine Major Impact Review Application Page 36 of 43 about ten years (2± years to complete mining of Area 1 and 8± years to mine Area 2) and the expansion area (Mining Area 4) will take 10± years to mine. Mining Area 4 is 22± acres and rectangular is shape. According to information presented at the public hearings for the Blue Pit expansion, Mining Area 4 is divided into four similarly sized phases and their plan is to mine the southeast corner as phase 1, the southwest corner as phase 2, the northeast corner as phase 3 and the northwest corner of phase 4. The 5.5± acre Phase 2 portion of Mining Area 4 is immediately adjacent to the Cerise Mine site. Based on the projected timing of the Cerise Mine and the Blue Pit mining activities, there will be just 2-2.5 years when the Blue Pit will be mining immediately adjacent to the Cerise Mine in Phase 2. This is difficult to understand in words, there for Cumulative Impact Analysis Site Plan graphics are provided in Section 15 of the application to make it easier to understand the progression and timing of the Cerise Mine in relation to the Blue Pit. It is important to keep in mind that Western Property Advisors was not involved in the creation of this graphic. Therefore, the graphic representation of their mining plan is based on our understanding of how they plan to proceed (we reviewed their mining plan map and attended their public hearing presentations regarding the application). As you can see from the graphics, the overall impact of mining on the area will not be significantly different from what it has been in the future. While the location of the mining activity is changing, the overall amount of land being disturbed will not significantly increase. This is especially true of the mining activity that Lafarge is responsible for since the Powers Mine will be completed and in the process of reclamation before mining begins at the Cerise Mine site. • Traffic on Highway 82 will not increase as a result of having the Blue Pit and Cerise Mine operating at the same time. The Blue Pit and Lafarge's Powers Mine both currently access the highway and, in the future, the Blue Pit will continue to access the highway and Lafarge's traffic will just shift from being generated by the Powers Mine to being generated by the Cerise Mine. There will actually be safety improvements with the Cerise Mine access versus the existing Powers Pit access situation. This is because the Cerise Mine will utilize an existing access onto the highway (County Road 103) rather than take direct access onto the highway as the Powers Mine currently does. • The Cerise Mine will access County Road 103 (Crystal Springs Road). The location along County Road 103 was located to be south of any residential development to prevent trucks from driving on the local roads adjacent to homes. In addition, the access was located at a point along the County Road 103 that will allow for good site distance conditions. • The traffic study that was conducted as part of the Cerise Mine application takes the Blue Pit traffic into consideration. The study indicates that the Cerise Mine will not adversely impact the area street system. The only improvements that the traffic study identified as being necessary are: o The west bound right turn deceleration lane on Highway 82 for vehicles turning right/north on County Road 103 and the east bound left turn acceleration lane for vehicles turning left/east onto State Highway 82 from Cerise Mine Major Impact Review Application Page 37 of 43 County Road 103 are substandard based on current CDOT Access Code criteria and need to be improved to meet current design standards. o Turning radii on the east side of the Highway 82 and County Road 103 intersection will be increased to be capable of serving a WB-67 design vehicle. o Striping changes to compliment the intersection improvements are needed. o Truck warning signs need to be installed on the County Road 103 approaches to the site access and a stop sign will be needed on the access approach to County Road 103. The Traffic Impact Study concludes that with these improvements in place, acceptable levels of service will be achieved and maintained through the long-term for all traffic movements at all intersections. Therefore, Lafarge is committed to making each of these traffic related improvements. • Lafarge will implement a fugitive dust control plan during operations at the Cerise Mine. Their plan will involve the following dust control measures and best management practices to reduce fugitive dust generation from the mine: o Exposed areas will be vegetated or stabilized to limit wind erosion and to provide screening. o When necessary, a water truck will spray the gravel as it is removed and transported. o Water spray bars will be installed, operated and maintained in the conveyor system and crushing and screening plant. o Drop heights of gravel will be limited for conveyor loading, transfer points, screening and crushing. o On-site vehicle speeds will be limited. o Frequently traveled on-site roadways will be sprayed with water to minimize re-entrainment of dust from the surface of the road. o Dust from loaded haul trucks will be limited by covering or watering as necessary. o A minimum 50 foot setback around the Cerise property will be maintained to allow any fugitive dust to settle before being carried by wind. o Emission controls and limits as required by CDPHE will be enforced and followed. o Berms and mine walls will be constructed to serve as wind breaks. o The site will be reclaimed once mining has been completed. In addition, both Lafarge's Cerise Mine and Western Slope Aggregate's Blue Pit are required to meet the new National Ambient Air Quality Standards at each property's boundary and these new air quality standards consider background concentrations of pollutants. Therefore, the Cerise Mine will be required by the State to operate in a manner that will prevent an air quality cumulative impact. Lafarge had a noise analysis report prepared for the Cerise Mine to ensure that the proposed operations at the site would comply with State of Colorado/Garfield County noise regulations. As suggested in the noise analysis report, Lafarge will follow these noise mitigation measures: Cerise Mine Major Impact Review Application Page 38 of 43 o The two "Vegetated Screening Berms" as called out on the Berming Screening and Buffering Plan (See Section 15 of the application) will be constructed at the beginning of the project (prior to Phase 1 mining). o The concrete plant will be oriented so that the dust collector on top of the plant is oriented away from the residential homes to the north. o Line power will be used on-site and if any electrical generator is used for back-up power, it will be equipped with a commercial grade silencer. o Lafarge's earth moving equipment will be equipped with white noise back-up alarms and backing-up by contractor vehicles not outfitted with these alarms will be minimized. • Lafarge will not affect water quality with the Cerise Mine because no water will be discharged from the site due to the fact that groundwater will not be encountered during mining. Process water will be contained on site, treated, and, in some cases, reused. In addition, consistent with County and State regulations, a Drainage Report and Erosion and Sediment Control Plan have been prepared for the site to make sure that stormwater is handled properly so as to not create any water quality issues. • There are neighbors that are located north and above the Cerise Mine site in Wooden Deer Subdivision. By virtue of the elevation change from where the neighboring homes are located down to the Cerise site, there will be some visual impacts; however, Lafarge is committed to doing what they can to address visual impact concerns. In order for all parties involved to have a realistic understanding of the visual impacts associated with the mine, Lafarge had a computerized visual impact study model prepared. The model uses 2' topographic contours that were obtained by Lafarge for the Cerise Mine site in conjunction with USGS topography for the areas around the site. The model then pulls in the proposed topographic features (mining cells as well as overburden and topsoil stockpiles) of the Cerise Mine per the proposed mining and reclamation plans. Existing and proposed vegetation is also built into the model (existing trees shown in the model were located based on information pulled from Google Earth aerial mapping). Using the model, we can navigate to surrounding properties and look at the Cerise Mine site to get a realistic view of what will be seen. As expected, the model shows that the entire site is not screened; however, it also shows that the screening and berming that is proposed is effective at mitigating the visual impacts. Screen shots from the model are provided in Section 15 of the application. 8. Unless otherwise determined by the Board of County Commissioners, the gravel pit hours of operation will be 7:00 a.m. to 8:00 p.m. Monday through Saturday with crushing, digging, and heavy hauling allowed from 7:00 am to 6:00 pm allowing for administrative and maintenance activities to take place until 8:00 p.m. No operations except emergency maintenance to ensure the integrity of operating equipment shall take place on Sunday. The Cerise Mine will operate during these hours, as allowed by the Garfield County Code. Cerise Mine Major Impact Review Application Page 39 of 43 H. Reclamation / Enforcement Reclamation shall be done to create an aesthetically pleasing site or reclaimed area that will blend with or improve upon the surrounding areas. All applications shall submit a Reclamation Plan that specifically addresses the following aspects of reclamation: slopes, vegetation, lake / pond shape & character, wildlife habitat / agriculture, phasing and berms. Additionally, The State of Colorado Division of Reclamation, Mining and Safety has minimum standards for reclamation. For example, reclaimed slopes are typically required to be 3:1 or shallower. This standard creates stable slopes but does not necessarily result in a landscape that blends with the surroundings. The same is true for other aspects of reclamation. All Reclamation plans shall follow the following design criteria: 1. Slopes (See illustration below) (Resolution 2009-88) a. Wetland Slope Areas: 1. Wetland Slopes shall be predominantly 5:1 or shallower, with at least 80% 5:1 and 20% 10:1 or shallower. The percentage of Wetland Slope is calculated along the perimeter of the reclaimed lakes. 2. For the purpose of this section, the Wetland Slope is defined as three (3) feet above the shoreline and three (3) feet below the shoreline (see graphic). 3. Wetlands shall be included in the reclamation plan, for all shoreline areas. 4. An alternate plan for the shoreline area which modifies the standards above may be proposed by an applicant to accommodate special needs for: a) Water based recreation amenities; b) Reducing wildlife habitat along certain sections of shoreline due to proximity to an airport; c) Fishing embankments; or d) Other special needs or uses that may be proposed by the applicant. 5. Any modification of the listed standards requires the recommending or decision making body to provide a separate finding and reason for waiving or modifying the Wetland Slope standards and that the modifications are in conformance with the purpose statement above: to create an aesthetically pleasing site that blends with the surrounding area, to provide for wildlife habitat and, to provide for future re -use of the site. Not applicable; there are no proposed wetland slope areas in the reclamation plan for the Cerise Mine. b. Dryland Slope Areas: 1. Dryland Slopes shall be predominantly 5:lwith at least 85% of the slopes 5:1 or shallower. 2. For the purpose of this section, the Dryland Slope area is defined as any area above a Wetland Slope in the post -mine land use that will predominantly be used for rangeland grazing and wildlife habitat. 3. An alternate slope plan for the dryland area which modifies the standards above may be proposed by an applicant to accommodate special needs when: a) The existing terrain slope is steep (greater than 5:1) or; b) Where there is little or no available on-site backfill material; c) Other special needs or uses that may be proposed by the applicant. 4. Any modification of the listed standards requires the recommending or decision making body to provide a separate finding and reason for waiving or modifying Cerise Mine Major Impact Review Application Page 40 of 43 the Dryland Slope standards and that the modifications are in conformance with the purpose statement above: to create an aesthetically pleasing site that blends with the surrounding area, to provide for wildlife habitat and, to provide for future re-use of the site. Lafarge proposes to reclaim the Phase 1 mining cell back to original grade and the Phase 2 through 4A mining cell with 3:1 slopes. This "alternate slope plan" is proposed because following the mining of the site, there will not be enough overburden material available to backfill the site to a less steep slope. In addition, the property owners, have agreed to 3:1 slopes and have asked Lafarge to re-vegetate their property with pasture grasses to continue the agricultural use that currently exists on their property. If shallower reclamation slopes were used, the amount offlat pasture area at the bottom of the slopes would be significantly reduced and not meet the needs of the property owners for how they want their land reclaimed. 2. Vegetation: All re-vegetation efforts shall occur as part of phased reclamation. (Resolution 2009-88) a. Wetland Criteria Not applicable; no portions of the property will be reclaimed with wetland vegetation. b. Dryland Criteria: 1. All dryland areas on a reclamation plan shall include re-vegetation with appropriate dryland plant species based on the written recommendation of a qualified professional consistent with 4-502 A, Professional Qualifications. The plan shall: a) Include a mixture of grasses, forbs and shrubs b) Seeding methods shall either use drilling with crimp mulching or hydro- seeding i. Mulch shall be weed free and shall be applied at a rate of no less than 3000 pounds per acre. ii. Hydro-seeding with hydro-mulching and tackifier shall be used on steep (greater than 5.1) slopes. Hydro-mulching shall be a minimum rate of 2000 pounds of wood fiber per acre. iii. If required, adequate irrigation shall be employed in re-vegetated areas during the life of the mine or until re-vegetation is self-sustaining based on the written recommendation of a qualified professional. 2. Any modification of the standards listed above requires the recommending or decision making body to provide a separate finding and reason for waiving or modifying the wetland re-vegetation standards and that the modifications are in conformance with the purpose statement above: to create an aesthetically pleasing site that blends with the surrounding area; to provide for wildlife habitat and; to provide for future re-use of the site. (Resolution 2009-88) Notes on the Landscape Plan (Section 13 of the application) indicate that the dryland seeding methods described above will be followed. 3. Lake / Pond Shape and Character: Reclamation with multiple ponds or lakes with substantial islands or peninsula (at least 20% of total surface) to break up surface, undulation of shorelines provides natural appearance. Not applicable; no ponds or lakes are proposed with the reclamation plan. Cerise Mine Major Impact Review Application Page 41 of 43 4. To the extent permitted by law, unless all disturbance created by the mining operation is covered by a reclamation bond under jurisdiction of the Colorado Division of Reclamation, Mining and Safety, or by the federal government on federally owned lands, a bond or other acceptable financial performance guarantee shall be submitted in favor of Garfield County in an amount of at least 150 percent of the cost of restoration of the site and access roads. The required amount of such financial performance guarantees may be increased at the discretion of the Board of County Commissioners to account for inflation. A bid for site restoration acceptable to the permittee and Garfield County shall be submitted to the Planning Department as evidence of the cost of reclamation for bond setting purposes. A cost estimate for reclamation will be submitted to the DRMS. The DRMS will review the estimate and then Lafarge will post a bond with the DRMS based on this estimate. A copy of the cost estimate that was submitted to and accepted by the DRMS is included in the Major Impact Review Application in Section 25. 5. To the extent permitted by law, the Board of County Commissioners may require a financial performance guarantee in addition to that required by the Colorado Division of Reclamation, Mining and Safety to insure that certain conditions of a permit will be complied with. The required amount of such financial performance guarantees may be increased at the discretion of the Board of County Commissioners to account for inflation. The County will not require financial guarantees that are duplicative of that required by the DRMS. See response to comment 4, above. 6. The operator will submit an annual report to the County Building and Planning Department with GPS measurements shown on a map showing the current disturbance, what areas have been backfilled, where topsoil stockpiles are located, all site structures, what areas have been seeded, mulched and what is planned for the ensuing 12 months. Upon commencement of mining, Lafarge will submit an annual report to the County regarding the status of the mining operation and reclamation. 7. The County commits to notifying the Operator of any compliance concern and allows an inspection with site personnel and the designated County inspector prior to contacting any agency. Noted 8. The County can request a site inspection with one day's notice to the Operator. Full access to any part of the site will be granted. On request, all paperwork must be shown. The County cannot request a large number of inspections that would interfere with normal operation without cause. Noted 9. A full list of all other permits shall be provided to the County. Any person at any time can call the following agencies directly and request an inspection if they believe a condition of that agencies permit is being violated. a. CDPHE Air Quality Control 303-692-3150 b. CDPHE Water Quality Control 303-692-3500 c. US Army Corps of Engineers 970-243-1199 d. Division of Reclamation, Mining and Safety 303-866-3567 e. CDOT Grand Junction office 970-248-7000 A copy of all permits that relate to the Cerise Mine will be provided once they are issued. a. Air permits are provided in Section 20 of the application. Cerise Mine Major Impact Review Application Page 42 of 43 b. The CDPS permit is provided in Section 26. c. A Nationwide Permit from the US Army Corps of Engineers will be obtained prior to constructing the access road through the wetlands adjacent to Crystal Creek. d. A 112 Reclamation Permit from the Division of Reclamation, Mining and Safety was submitted and is expected to be approved in January. A copy of the permit application was provided to the Garfield County Planning Department. e. No new access onto Highway 82 is proposed; therefore no access permit from CDOT will be required. However, an access permit from Garfield County will be obtained. 10. The County will be invited to any bond release inspection of the State Division of Reclamation, Mining and Safety. The County inspector will have the opportunity to demonstrate that any item of the permit has not been complied with and that bond should not be released. Noted 11. The Operator acknowledges that the County has performance standards in place that could lead to revocation of the Land Use Change Permit if continued violations of the permit occur over a period of time. (Resolution 2009-88) Noted 12. The County shall not issue a Land Use Change Permit until all required local, state, and federal permits have been obtained and submitted to Garfield County including but not limited to the municipal Watershed Permit, CDPHE, USACE, NPDES, Division of Water Resources (approved well permits and plan for augmentation), etc. (Resolution 2009-88) Noted 13. The reclamation plan approved by Garfield County as part of the land use change permit shall be resubmitted to the DRMS to become the only reclamation plan (tasks / timetables) used by both the County and DRMS. Additionally, a bond shall need to be calculated to cover this plan and secured with DRMS to cover its implementation. Noted 14. The applicant shall provide locations of county listed noxious weeds on a map. Once the inventory is provided the applicant shall develop a weed management plan that addresses all county listed noxious weeds found on site. This weed management plan shall be submitted to the County Vegetation Manager for approval prior to the issuance of a land use change permit. Please see the Natural Habitat Statement in Section 23 of the application regarding the weeds found on-site.

Todd Ohlheiser Vice President Name (Printed) Title Signature Date Cerise Pit Storm Water Management Plan Page 3 of 19 SECTION 1 Description of Industrial Activities This SWMP has been prepared for the Cerise Pit, which produces aggregates and ready -mixed concrete for use at construction sites in the Carbondale, Colorado vicinity. FIGURE 1 identifies the general location of the facility, as well as the nearest receiving waters. Construction activities present at the site are as follows: • GRADING/MINING Site is leveled and smoothed according to final project specifications using a road grader. Material may be excavated using earthmoving equipment and processed through various feeders, screens, and crushers. This may include right-of-ways, drainage ditches, and road sub -base areas of the project. ❑ QUARRYING Drilling and blasting is used to liberate virgin stone from its natural consolidated state. Haul trucks are typically used to take the material to the plant for processing. 1 STOCKPILING (Check if applicable) • OVERBURDEN AND TOP SOIL Stockpiles may occur in the form of earthen berms. • SAND AND GRAVEL Raw and processed aggregates are stockpiled for future use. • AGGREGATE MIX FOR CONCRETE PRODUCTION Aggregate can be stored in stockpiles, and loaded into a ground hopper as needed, and then conveyed to the plant. Material may also be loaded directly into a series of hoppers located above the plant that directly discharge into the plant. • AGGREGATE MIX FOR ASPHALT PRODUCTION Raw material can be stockpiled or put into storage bins. • RECYCLE ASPHALT PRODUCT Asphalt that is being stored and/or processed for reuse. • RECYCLE CONCRETE PRODUCT Concrete that is being stored and/or processed for reuse. ❑ ASPHALT MILLING The existing roadway is milled, emptied into haul trucks and hauled off-site. Cense Pit Storm Water Management Plan Page 4 of 19 ❑ ASPHALT PAVING Hot mix asphalt is transported to the project from a production plant located off-site. It is then placed, compacted and rolled according to project specifications. II ASPHALT MANUFACTURING A hot -mix asphalt plant blends together aggregate and asphalt cement to produce a hot, homogeneous asphalt paving mixture, which is then hauled to off-site construction projects. The aggregate used can be a single material, such as a crusher run aggregate or a pit run material, or it can be a combination of coarse and fine aggregates, with or without mineral filler. The binder material used is normally asphalt cement but can also be an asphalt emulsion or one of a variety of modified materials. Various additives, including liquid and powdered materials, can also be incorporated into the mixture. Activities at these sites may include the following: raw material unloading into stockpiles or storage tanks, raw material feed to plant, material batching, raw material storage area, recyclable asphalt disposal area, truck wash out, and water supply and settling lakes. ❑ READY MIXED CONCRETE, CENTRAL BATCHING These operations mix sand, gravel, cement, and water together to form ready mix concrete, which is then hauled to off-site construction projects. The raw materials are made up of sand, gravel, cement, water and additives. The sand and gravel is either stored in stockpiles located outside and fed into the plant via loaders and conveyors, or it is stored directly in a series of hoppers located directly above the central plant. The remainder of the raw materials is stored in tanks to protect them from exposure to moisture and temperature until they are pumped into the mixer. Once the raw materials are fed into the central mixer and combined to form Ready Mix concrete, the final product is placed within trucks and removed from the site. ■ READY MIXED CONCRETE, DRY BATCHING These operations apportion out a mix of sand, gravel, cement, and water together, which is then mixed within the truck to form Ready Mixed concrete that is hauled to off-site construction projects. The raw materials are made up of sand, gravel, cement, water and additives. The sand and gravel is either stored in stockpiles located outside and fed into the plant via loaders and conveyors, or it is stored directly in a series of hoppers located directly above the central plant. The remainder of the raw materials is stored in tanks to protect them from exposure to moisture and temperature until they are pumped into the mixer. Dry batching then apportions out and dumps the raw materials into the concrete truck -mounted mixer where it is continually agitated and mixed to keep it from hardening before it arrives on the assigned job site. Cerise Pit Storm Water Management Plan Page 5 of 19 • EQUIPMENT FUELING Diesel and/or gasoline tanks are located on site for fueling of equipment. Off-site vendors refill tanks as needed. ■ EQUIPMENT MAINTENANCE The site contains a shop area where necessary maintenance can be conducted for site equipment. Typical chemicals associated with maintenance, such as used oil, antifreeze, motor oil, hydraulic oil, brake fluid, etc, may be stored on site as needed. All chemicals are stored in such a manner as to prevent materials from mixing with stormwater or being accidentally discharged off site or to waters of the U.S. SECTION 2 Site Map * Figure 2 will be updated to include all site specific BMPs and other site characteristics once the site is approved and prior to beginning operation. The map can not be updated until the site is approved and final plans are developed. Enclosed is FIGURE 1: Site Vicinity Map and FIGURE 2: SWMP Site Plan; which indicates site-specific characteristics and BMPs implemented. The site has been determined to be within a single drainage area. Soil berms and/or high walls along all sides of the facility serve as barriers to prevent run-on from and run-off to adjacent property. The site comprises of approximately 99 acres, 66 of which will be mined in five phases. The property has a natural slope to the south towards Highway 82, which forms the southern property boundary. The Roaring Fork River is the largest nearby stream; it is located to the south of Highway 82. Crystal Creek is a smaller waterway tributary to the Roaring Fork River. It is located along the western edge of the property. The mined pit floor has a general slope to the south. Several holding ponds and depressions provide storage for process and storm water on site. Directions of stormwater flow, locations of BMPs, location of all surface water bodies, inflow areas, and outflow areas are indicated on FIGURES 1 and 2. The nearest receiving water that may receive storm water flows from the facility is Crystal Creek which confluences with the Roaring Fork River (FIGURE 1). However, a tailings / detention pond is designed to contain all storm water on site. During operations the site will be graded to Cerise Pit Storm Water Management Plan Page 6 of 19 minimize the amount of ponding on the property. Process water, primarily created from the washing of aggregates, will be recycled and reused. Water from the wash plant that can not be used will be sent to a silt pond. There will be no discharge of process water from this plant. The unmined portions of the site are vegetated to also act as a buffer and the overburden stockpiles will be vegetated. The following is a list of specific information included on the Site Map(s): ✓ Site boundary ✓ Access & haul roads ✓ Stormwater outfalls and an outline of each drainage area for each outfall 1 An estimate of the direction of flow ✓ Material handling areas ✓ Each structural control measure to help reduce pollutants in stormwater runoff ✓ Areas used for storage or disposal of overburden, materials, soils, or wastes ✓ Areas used for mineral milling & processing ✓ Springs, streams, wetlands and other surface waters ✓ Location of mine drainage or any other process water discharge points ✓ Boundary of tributary area that is subject to effluent limitations ✓ Date the map was prepared and subsequent revision dates SECTION 3 Stormwater Management Controls This section describes the development and implementation of stormwater management controls specifically designed for the Cerise Pit including: SWMP Administration, identification of potential pollutant sources and Best Management Practices (BMPs), sampling information, preventative maintenance, good housekeeping techniques, Spill Prevention and Response Procedures, employee training, and identification of discharges other than stormwater.

Cerise Pit Storm Water Management Plan Page I I of 19 Sampling Information The current plan does not include discharging process water from the Cerise Pit. Per CDPHE regulations, no sampling will be required under this plan. Existing Discharge Sampling Data Sampling Point Quantity of Discharge Pollutants NA — Proposed Sampling Points Sampling Point Description of Location Monitoring Requirements NA Preventive Maintenance Daily inspections of all storage and activity areas are conducted as a part of the operation. Comprehensive inspections are completed as required based on activity at the site (please see Section 4 for additional details). Inspections include at a minimum the following: • Integrity of diesel storage tank and secondary containment • Integrity of perimeter berms and truck wash out berms • Fuel spills in diesel fueling area, and material spills in the silo area and mixer area. • Open aggregate storage bins Cerise Pit Storm Water Management Plan Page 12 of 19 • Air and oil leaks on machinery and equipment • Belts, pulleys, rollers, and gates on plant equipment Cleaning and maintenance is performed as needed and in response to inspection results. Records of these inspections are available through the plant manager or another member of the site SWMP Administration Team.

This is accomplished through proper operation and maintenance of machinery and processing equipment. Careful material storage practices have been implemented. House keeping includes prevention and/or reduction of spilled aggregate and other particulate material. Principal good housekeeping procedures are as follows: • The material inventory is kept up to date, and all containers are labeled with the name and associated hazards. • Material safety data sheets (MSDS) are available on site to ensure that operation staff is aware of hazards and pollution potential. • Routine cleanup operations are ongoing and scheduled to ensure that the storage areas and maintenance areas are clean and orderly. • Good housekeeping, including cleanup procedures and disposal requirements, are incorporated into employee training. • Solid waste receptacles are available on site and are emptied regularly. Cerise Pit Storm Water Management Plan Page 14 of 19 Spill Prevention and Response Procedures The facility contains sufficient amounts of stored petroleum products as to require the development of a formal Spill Prevention, Control, and Countermeasure (SPCC) Plan, a copy of which is kept on site. Training and procedures established under SPCC rules are applied to all petroleum storage within Lafarge facilities. Secondary containment is provided for the diesel fuel storage tanks should releases occur. Removal of accumulated liquids from the containments is accomplished by use of absorbents, portable pump, or other technique, and waste material is properly disposed. In the event that a spill occurs: o Do-- • Shut off supply, stop leak (if possible) • Shut of ignition sources • Contain spill and/or dike ahead of spill • Notify Plant Manager. If the spill leaves the site or is greater than 25 gallons, the Plant Manager will notify Environmental Department. • Protect adjacent people, property, surface waters, and equipment from contact with spill • Look to Material Safety Data Sheets (MSDS) for clean up guidance • Follow site SPCC plan • Place absorbents, dirt, or other solid materials in a non -leaking container and dispose of according to state and federal regulations o Don't— • Smoke • Risk personal injury • Wash down spill with water • Cover and not cleanup spill The majority of manufacturing process includes solid earthen materials with inert properties that would not impair surface or groundwater characteristics. The most common liquid not covered under the facility petroleum management plan would be process water used in the production of aggregate and concrete, and small amounts of cleaning liquids that have no identified impairment of surface or ground water. Cense Pit Storm Water Management Plan Page 15 of 19 Employee Training Training of personnel is conducted annually to educate employees, at all levels of responsibility, about the components and objectives of the storm water management plan for the site. The training scope will include the following topics: Spill Prevention Spill Response Good Housekeeping Techniques Materials Management Sediment & Erosion Prevention Definition of Process Water Best Management Practices in Place and Proper Maintenance While operations are conducted on site, it will be the responsibility of the site manager or operator in charge to train appropriate on-site personnel so that the goals of the SWMP are achieved. Various other types of environmental training are conducted at different levels of the site management. Environmental Training topics are produced for `tailgate' meetings to discuss site- specific environmental management. Site managers participate in a number of internal and industry management meetings where environmental pollution control, regulations, and responsibilities are discussed. Records of personnel training conducted, including personnel in attendance, date of training, and scope of training are available through the facility manager. Identification of Discharge other than Stormwater The site has been evaluated for the presence of non-stormwater discharges. Water associated with portable wash plants for processing aggregate and water used in the production of concrete are the primary sources of non-stormwater on site. All other sources are contained within the site and are not discharged with stormwater. Water stored and applied on site for dust abatement Cerise Pit Storm Water Management Plan Page 16 of 19 is periodically utilized on the yard site and the access road to suppress fugitive dust. Applied dust control is not applied in excess amounts that would result in an off-site discharge of liquids. Dust abatement is not necessary during precipitation events; therefore, no non -storm water at the site is intermingled with storm water runoff. Water and other liquids utilized in other peripheral uses and in the production of aggregate are contained within the plant. Any mechanical failure with the potential to allow a surface release would be addressed through the site's spill response or emergency response protocols, free liquids would be isolated and adsorbed, and adsorbents properly disposed. Currently, no stormwater or commingled process water are in sufficient quantities to discharge from the site. Should subsequent water uses be initiated on site, these water sources will be identified in the table below: Types of Discharge No Discharge Permitted Process Water Unpermitted Exempt Control Measures Mine Dewatering X Equipment Wash Water X Dust Control (roads) X Irrigation return flows X Other Agricultural discharge X Fire Fighting discharges X Foundation Draining(SUMP) X Springs X Other Other Cerise Pit Storm Water Management Plan Page 17 of 19 SECTION 4 Comprehensive Inspections Comprehensive inspections performed by qualified individuals, record keeping and internal reporting are essential activities under the SWMP and are outlined below. All records and reports are to be maintained with the plan at the managing office. Qualified personnel shall make a comprehensive inspection of the stormwater management system at least twice per year in the spring and fall for all active facilities. For idle sites where an employee is not stationed or does not routinely visit the site, inspections shall be conducted every two years. For inactive sites, inspections shall be conducted every three years. These comprehensive inspections must be documented and summarized in the Annual Report. Material handling areas, disturbed areas, areas used for material storage that are exposed to precipitation, and other potential sources of pollution identified in the SWMP in accordance with the permit shall be inspected for evidence of, or the potential for, pollutants entering the drainage system. Structural stormwater management measures, sediment and control measures, and other structural pollution prevention measures identified in the plan shall be observed to ensure that they are operating correctly.

Cerise Mine — Drainage Report TETRA TECH August 10, 2010 DRAINAGE REPORT CERISE MINE — GARFIELD COUNTY, CO 1.0 INTRODUCTION This report summarizes the drainage analysis and plan for the proposed Cerise Mine located at the intersection of State Highway 82 and Crystal Springs Road east of Carbondale, Colorado. (See Figure 1: Vicinity Map). The project is bound to the west by Crystal Springs Road, to the south by Highway 82, and to the north and east by open farm land. The land is currently used for agricultural purposes. A gravel mining operation with a concrete plant and a temporary asphalt plant is currently being proposed at the site. The purpose of this report is to discuss the existing and proposed grading and drainage and to address surface water runoff issues. The project has three phases included in the drainage analysis including the existing condition, the final mining layout, and the restoration condition. This drainage report provides the results of the analysis for all three conditions and includes the recommendations for proposed drainage based on the Garfield County Regulations. The proposed storm water plan has been developed to adhere to the requirements of Garfield County, which requires that the existing runoff rates from the site are not exceeded by the proposed condition for the 25 -year, 24-hour storm event. Detention facilities must detain or safely pass the 100 -year storm event. Lafarge West, Inc. Cerise Mine — Drainage Report 1 TETRA TECH August 10, 2010 DRAINAGE REPORT CERISE MINE — GARFIELD COUNTY, CO Figure 1. Vicinity Map 2.0 DRAINAGE ANALYSIS 2.1 Existing Conditions The Cerise Mine site of approximately 47 acres is located on the north side of Highway 82 on a high bench that is approximately 80 feet above the highway. The Roaring Fork River is located to the south of the highway and another 25 feet +/- lower than Highway 82. The entire site is located outside of the floodplain and floodway of the Roaring Fork River and sits over 100 feet higher than the Roaring Fork River Base Flood Elevation (BFE) based on the FEMA Flood Insurance Rate Mate for Garfield County, CO (unincorporated areas) Community Panel 080205 1880B. Lafarge West, Inc. Cerise Mine — Drainage Report 2 TETRA TECH August 10, 2010 DRAINAGE REPORT CERISE MINE — GARFIELD COUNTY, CO Crystal Creek is a smaller stream that runs along the western border of the mining site. This creek is not included in the FEMA mapping for the area. However, the river is over 25 feet lower than any adjacent mining activity and over 60 feet horizontally from the closest grading extents. There will be no mining in the floodplain of the creek, which has a 100 -year discharge of approximately 200 cfs. The site is not visible from Highway 82 as it sits at the top of a steep embankment. The site is currently used for agriculture and consists of open meadow with minor access roads. A small irrigation ditch exists on the northern border of the site and a smaller collection swale exists closer to the center of the field. Surface water runoff rates and volumes are estimated using a combination of methods. For the larger basins, the SCS Method is used assuming a 24-hour storm distribution, initial infiltration loss of 1 inch and precipitation values determined using the NOAA Interactive Precipitation Atlas. For the smaller basins, the Rational Method of peak flow and volume estimation is used. There are three offsite basins that contribute flow to the project site as seen on Figure ER - 10 and ER -11. Basin A is the largest and includes Crystal Creek. All surface flows from this basin reach Crystal Creek (without flowing through the project site) which flows to along the western border of the site, toward the southwest under Highway 82 in a 36" culvert. The 100 -year 24-hour storm is estimated to produce 198 cfs in Crystal Creek at the project site. Flows from the Basin B, the offsite basin to the north, are collected in the irrigation ditch located just above the northern border of the project site. This ditch flows towards the west and discharges into Crystal Creek. Flows from Basin C (to the east of the project) follow a generally southern overland direction. Flows reach the swale that is located along the north side of Highway 82 that flows west toward Crystal Creek. This basin is included in the existing conditions analysis to account for all of the potential flow that reaches the Crystal Creek culvert under Highway 82; however, the flows from this basin do not otherwise have an impact on this project. The project site is located within Basin D. Flows from this basin travel to the south and west, reaching Crystal Creek and the Highway 82 swale. The runoff from the project area and contributing offsite areas all ultimately discharge into Crystal Creek which flows under Highway 82 in a 36" CMP culvert towards the Roaring Fork River. It should be noted that this culvert is currently undersized and Lafarge West, Inc. Cerise Mine — Drainage Report 3 TETRA TECH August 10, 2010 DRAINAGE REPORT CERISE MINE — GARFIELD COUNTY, CO flooding of Highway 82 is a possibility during the larger return period storms. Redesigning the culvert is not within the scope of this project. Refer to Table 1 for the total runoff rates for the existing site and offsite basins. Additional calculation information can be found in Appendix A. Table 1— Drainage Summary for Existing Conditions Basin Drainage Area (acres) Discharge (cfs) 25 -year 100 -year A 2,029 81.3 150.4 B 136 7.8 15.2 C 307 33.2 63.4 D 142 10.1 23.3 Crystal Creek 2,614 108.4 198.2 2.2 Proposed Conditions 2.2.1 Final Mining Configuration Phase The proposed development site will contain a gravel mining operation, which will require the construction of gravel pits and processing equipment. See Figure ER -12. A large tailings pond will be constructed near the southwest corner of the site. The tailings pond will also serve at the detention pond. A minimum of 0.12 acre-feet will be required in the pond to capture and detain the 100 -year runoff for proposed mining conditions. The mining excavation operations will all be conducted on dry land as the excavation is not proposed to access the groundwater table. However, a stability analysis of the impact of the pond on the adjacent slope is being conducted. Further information is contained in the Stability Analysis Report for Lafarge Cerise Property. During the development of the mine site, the excavation operation location will change slightly until the final configuration can be achieved. Surface water flows will be directed toward the tailings/ detention pond during all phases of mining operations. However, as the exposed surface will be primarily gravel, it is expected that the infiltration rate will be such that a small percentage of rainfall will actually reach the detention pond. To be conservative, sizing calculations assume all flow will reach the tailings / detention pond. Storm water runoff from the contributing offsite areas will be routed in existing patterns. Existing irrigation ditches will be maintained to convey offsite runoff around the site where it will discharge into Crystal Spring per the existing drainage pattern. Storm water runoff from the proposed site will be collected and routed into the proposed tailings / detention pond where it will be reused for mining operations or allowed enough time to Lafarge West, Inc. Cerise Mine — Drainage Report 4 TETRA TECH August 10, 2010 DRAINAGE REPORT CERISE MINE — GARFIELD COUNTY, CO infiltrate into the groundwater. Table 2 includes the results of the drainage calculations for proposed conditions. See Appendix A for additional calculations.

The asphalt plant is temporary and will move with the aggregate plant. This area will drain toward the southwest and runoff will be diverted through an oil and grease separator before being discharged into the tailings / detention pond. 2.2.2 Reclamation Phase The reclamation phase will consist of the final basin lowered approximately 100 feet, with 3:1 slopes and bottom, all revegetated to mimic existing conditions. A gravel access road will remain to access the bottom of the basin. See Figure ER -13. Flows from this area will reach the bottom of the basin and will infiltrate into the ground water. The tailings pond will be reclaimed back to original grade, half of which will slope towards Crystal Creek and the other half will slope towards the lowered basin. This area will also be revegetated. As no additional impervious area will be created compared to existing conditions, detention of surface flows is not necessary to maintain existing conditions flow rates. 2.2.3 Site Access The site will be accessed by a new entrance road which will cross Crystal Creek. A 60" HDPE culvert will be used to convey the 100 -year flow of 198 cfs under the road. A HEC -RAS model was created to evaluate the impact of the culvert on the water surface elevations. The culvert will be inlet controlled and will have approximately 5 feet of Lafarge West, Inc. Cerise Mine — Drainage Report 5 TETRA TECH August 10, 2010 DRAINAGE REPORT CERISE MINE — GARFIELD COUNTY, CO head above the top of the culvert. The water surface will however be approximately 15 feet lower than the entrance road. The HEC -RAS model report is located in Appendix B. 4.0 CONCLUSION In combination with surface conveyance features such as irrigation ditches, swales, oil and gas separators and the tailings / detention pond, this drainage system design will successfully control storm water runoff and prevent any increased runoff from leaving the project site. Overall, the storm water plan addresses both the quantity and quality of runoff from the site and conforms to the requirements set forth by the Garfield County standards capturing runoff, therefore lowering the post- development runoff rate from the pre -development condition for the 25 -year, 24 hour storm as well as the 100 -year, 24 hour storm.

Box 1659 Breckenridge, Colorado 80424 This system design is based on Garfield County Health Department and the State of Colorado ISDS Regulations. It is assumed that the Cerise Mine site will have a single field that serves the main office. The site will be a gravel mine that will operate approximately 15 years before this area would be mined. Based on the need to fix the location of the field where it will not be disturbed by mining operations around it, a site adjacent to the office has been chosen between the scale and the main parking to insure drainage does not affect the percolation of effluent. For that reason, a mound system has been chosen to elevate the field and insure protection of the system. Since the field location will be located anywhere from 10-15 feet below the existing grade, a percolation test was not done. Instead, the drill logs from the site exploration for the site have been used to estimate the long term acceptance rate (LTAR). A drill log fairly close to the proposed site classifies the area at the estimated field location as sandy with some gravels and traces of silt and clay. Based on this, a coarse to medium sand classification will be used for soil absorption sizing. Once the site is excavated, a percolation test will be done to test the actual rates in the field. The field will be a mound system that will treat less than 2000 gal/day. SOIL ABSORPTION AREA SIZING 1) Estimate Average Daily Flow: The mine site will employ anywhere from 20-35 full time employees, with 2-3 of those people full time in the main office that will be served by the system. There could also be up to 10 temporary employees onsite if a portable asphalt plant is brought to the site for a specific job. Throughout the site, "porta potties" will be located for site workers but there may be instances where the workers could use the facilities. Usage has been calculated based on the "Factories and Plants" classification without showers. This is a conservative approach to calculating the flows anticipated for the office and should provide a solid system design. Usage for each employee is estimated at 20 gallons per employee per day. 2) Estimate Maximum Daily Flow: Factories and Plants: 20 gal/employee/day 20 gal/day x 35 people x 1.5 = 1050gal/day 3) Estimate Maximum Flow per Dose 1050 gal/day x 1 day/4 doses = 262ga1/dose The application rate is based upon the estimated soil's percolation rate. The LTAR has been estimated to be at 1.2 gal/sf/day with the sandy material, (see Test hole #10 Enviro Group logs).

Seed mixture must be certified as weed free. A minimum of ten (10) pounds of seed shall be applied. 11) Following seeding, a layer of straw shall be applied over the mound cover to protect the seed and retain moisture. To insure no side slope erosion, seed and straw area shall be netted and staked down. 12) Contractor shall irrigate the mound cover as part of site clean-up and apply a minimum of three-quarters (3/4) of an inch of water to the mound cover. SEPTIC TANK AND LIFT STATION CONSTRUCTION AND PUMP STATION NOTES: 1) Use Hydromatic SHEF 30 pump in lift station or equivalent approved by Engineer. Final pump sizing will depend on final tank elevation. Contractor to review with engineer prior to ordering. 2) Use a three (3) compartment concrete tank. First two compartments to have 1250 gal. capacity. Third compartment for lift station to have capacity of 400 gal. minimum. Bury depth to be approximately 2'. 3) Concrete tank to be placed on bed of 3/4" washed rock a minimum of 6" deep. Backfill to be clean native material with no material larger than 2" diameter. 4) Inlet and outlet openings of tanks to be properly sealed to be water tight. 5) The mound shall be dosed four (4) times daily.

Enough water must be applied to have the surface of the soil adequately moist, yet not enough water to cause a runoff of mulch and seed. This may be accomplished by turning the system on for approximately 30-40 minutes for rotary head systems for four to six waterings the first day or two until proper saturation of subsoil is accomplished. After the first two days you may find that 25-40 minutes for rotary systems, three (3) times per day for the next three (3) weeks more or less, according to the soil's ability to hold water, will be sufficient to keep surface looking damp at all times. On cloudy days, water may be lessened to one to two times daily. Do not water after 6:00p.m. if possible. Water during day light hours whenever possible as this is the time most transpiration occurs and the new seedlings are most vulnerable. Watering of Plant Material A thorough watering of all newly planted plant material is necessary immediately after planting. The surrounding soil of the new plant may be in an extreme dry condition which will draw the moisture from the plant root balls and cause shock to the plants which may later cause a loss of plant material. All newly planted material must be watered once a day for three consecutive days to make sure all air pickets are eliminated and plants set firmly in place. After this initial watering, once a week or every ten days should be ample. However a test should be made by inserting a finger into the soil around the plant to judge the amount of moisture in the soil. Naturally, in extreme hot weather as in July and August, it may require more frequent watering. Good judgement and caution must be taken not to over water or drown the plants. It is important to note that trees can suffer from too much water as easily as they can from lack of water. There are definite signs of over watering, such as yellowing leaves or total loss of leaves. On the other hand, lack of water will cause the leaf edge to turn brown and brittle, then a total dehydration of the leaf will cause the plant to become void of water, and it will soon die. It is an accepted practice to plant pines and deciduous shade trees 2"-4" above ground level. This method of planting aids in preventing oxygen starvation and eventual drowning of plant materials planted too deep or in wet areas. If the ground drains well, the ball can be planted even with the ground level or with the bud of the deciduous tree just below the surface of the ground. Fertilization of plant material is not needed the first year of planting. The second year, a small handful of balanced chemical feed, 10-6-4, can be supplied around the base of the plant, 6" from stems. Cultivate it into the soil 2" deep, then water thoroughly. Spraying all the plant material with Malathion or Lindane is recommended once a month. A minimum spraying of two or three times per year is a must. Spraying more often is necessary if damaged by insects is evident. Deciduous shade trees should be fed in the following way. Make holes one foot deep and one inch in diameter, then fill the hole up with fertilizer, 10-6-4. Use 2 lbs. of fertilizer per caliper inch. This will gradually be assimilated by the trees as water dilutes the fertilizer into the soil and root zone. Plants must be watered thoroughly at least once per month during November, December, January, February, March and April for the first year as they dehydrate rapidly in the Colorado climate.

Drawn By: D.Q.B Checked By: G.L.W 2 Bar Measures 1 inch Copyright: Tetra Tech Cerise Mine Land Suitability Analysis 1. Public Access to the Site The attached Land Suitability Analysis map shows the historic public access to the Clifford Cerise Ranch Co, L.L.L.P. property. In order to minimize impacts on existing residential development, this historic access will not be used for the Cerise Mine. Instead, a new access will be constructed onto County Road 103. The proposed access onto County Road 103 is also shown on the Land Suitability Analysis map. 2. Access to adjoining Roadways The proposed access to County Road 103 is shown on the Land Suitability Analysis map. According to the County, the speed limit for County Road 103 is 25 MPH and so the access to the site was located as proposed to ensure that it can meet site distance requirements. There are no intersection constraints associated with this new access point onto County Road 103 or with the intersection of County Road 103 and State Highway 82. 3. Easements All existing easements are shown on the Land Suitability Analysis map. 4. Topography and Slope The existing topography for the Cerise property is shown on the Land Suitability Analysis map. The slopes within the permit boundary of the Cerise Mine are primarily less than 20% slopes. However, there are a few places within the permit boundary (on the edge of the permit boundary, on the south side of the permit boundary and where the access road from the mine to County Road 103 will be located) where the slopes are steeper. Please see the Existing Slopes Plan (sheet ER -5) sheet of the Erosion and Sediment Control Plans set. 5. Natural Features Natural features both on-site and off-site are depicted on the Land Suitability Analysis map. 6. Drainage Features The existing drainage features for the Cerise property are the Basin Ditch, irrigation laterals that cross the property and Crystal Creek. These features are shown on the Land Suitability Analysis map. 7. Water The Cerise property has historically been irrigated with water from the Basin Ditch. As part of the lease agreement between Lafarge and the Clifford Cerise Ranch Co, L.L.L.P., Lafarge has the right to use this irrigation water for the mining operations. These water rights may be used by Lafarge to irrigate the vegetation on the property during the life of the mine and are not anticipated to be used for production purposes (they cannot be used for production uses unless Lafarge requested a change in the use of these water rights from water court). Therefore, Lafarge will lease water from the Basalt Water Conservancy District for all of the consumptive Cerise Mine Land Suitability Analysis Major Impact Review Application Page 1 of 2 use needs (both production and domestic needs). The leased water will be obtained for use at the Cerise Mine site via two wells; one production well and one domestic water well. Please see the documentation provided in Section 16 of this Major Impact Review application for more details and the County required documentation regarding the use of water at the Cerise Mine site. 8. Floodplain The Cerise Mine site is not within a floodplain. Please see the note regarding the floodplain on the Land Suitability Analysis map. 9. Soils According to the mapping available on the Natural Resources Conservation Service's (NRCS) website (http://websoilsurvey.nrcs.usda.gov/), the soils found on the Cerise Mine property include: Almy loam, 1 to 12 percent slopes Empedrado loam, 2 to 6 percent slopes Fluvaquents, 0 to 10 percent slopes For more information about the soils, please see Section 17: Geotechnical Information and Section 24: Soils Information of the application. 10. Hazards There are no known existing geologic hazards on or adjacent to the Cerise Mine site and no geologic hazard will be created as a result of mining the site. Please see the Stability Analysis letter found in Section 17 of the application for more information. 11. Natural Habitat Please see the Natural Habitat Statement report found in Section 23 of the application. 12. Resource Areas There are no protected or registered archaeological, cultural, paleontological or historic resource areas on the Cerise Mine property. For more details, please see the Report on the Class I Cultural and Paleontological Resources found in Section 18 of the application. Cerise Mine Land Suitability Analysis Major Impact Review Application Page 2 of 2 Cerise Mine Impact Analysis 1. Adjacent Property An address list of real property adjacent to the subject parcel and the mailing address for each of the property owners is provided in Section 7 of this application. 2. Adjacent Land Use The adjacent land uses within 1500 feet of the Cerise Mine are gravel mining, residential, irrigated pasture, and riparian (along Crystal Creek and the Roaring Fork River). 3. Site Features The Cerise Mine site is located on a plateau that sits high above any FEMA floodplain as well as Crystal Creek, a stream that runs along the western edge of the site. The Basin Ditch runs along the north edge of the Cerise Mine, but it has been excluded from the Cerise Mine permit area so the ditch will not be affected by the mining operations and will remain operational where it is currently located. Details regarding the existing vegetation at the Cerise Mine site is provided in the Natural Habitat Statement which is in Section 23 of this application. In addition, the vegetative cover can be seen on the Land Suitability Analysis Map (Section 14 of the application). The groundwater elevation on the Cerise Mine site was measured at 96 to 99 feet below the ground surface. Lafarge will monitor the groundwater during mining to make sure all mining remains above the groundwater elevation. Climate data for the Cerise Mine site is assumed to be similar to that of the Glenwood Springs #2 (053359) weather station. The Western Regional Climate Center tracks temperature extremes and precipitation data for this station. The table on the following page includes data that was collected between September 1, 1893 and August 31, 2009.

The deposit is composed of various amounts of cobbles, gravels, sands, silts, and clays. The site subsurface Impact Analysis Major Impact Review Application Page 2 of 5 conditions were investigated through an exploratory drilling program conducted by Deere and Ault and EnviroGroup. The results of exploratory borings indicate that bedrock was not encountered to the maximum depth explored (119') within the proposed mine limit. From a geotechnical standpoint, sand and gravel will form most of the mine slope. These soils are generally strong and stable, particularly when no groundwater is present, as will be the case at Cerise Mine. Minor amounts of clay will lie at the ground surface and locally as lenses within the sand and gravel. For more information, please see the Stability Analysis Letter and Boring Logs found in Section 17 of the application. 6. Effect on Existing Water Supply and Adequacy of Supply Applegate Group determined that Lafarge will need up to 40.5 acre feet of water to satisfy their annual consumptive use requirements at the Cerise Mine site (see water requirements letter from Applegate Group in Section 16 of the application). The Basalt Water Conservancy District (BWCD) has agreed to lease Lafarge the water required to meet the projected consumptive use requirements of the Cerise Mine site. Documentation from the BWCD verifying Board approval of Lafarge's request as well as a proposed contract issued by BWCD are included in Section 16 of the application. The water that Lafarge will lease from BWCD will be obtained from a couple of wells on the property; one well will provide the production water and the other will provide potable water for domestic use in the office. In October 2010, Lafarge had two test wells installed on the site in the approximate locations of the wells that will be formally permitted through the State. Water quality tests were run on water out of the test wells and the water was found to be suitable for use as a potable water source with use of a simple water treatment and filtration system. More detailed information about the water quality test results can be found in Section 16 of the application behind the Water Well Documentation divider. A 24 hour pump test was also run on both wells and it was determined that the aquifer and wells can provide an ample supply of water to support the Cerise Mine. The pump test results can also be found in Section 16 behind the Water Well Documentation divider. In addition, Bence Close with EnviroGroup has written a letter regarding the Aquifer Pumping Tests. In the letter, Mr. Close indicates that based on the estimated water demands, the productivity of the existing wells or new wells would not be a limiting factor in obtaining well permits to satisfy the project needs. Therefore, we do not anticipate any problems obtaining the required well permits from the State and the approved well permits will be provided to the County prior to final approval of the application. The water leased from the BWCD will be used as makeup credits for the water removed from the ground water system and the Cerise Mine will automatically be covered by the BWCD's Substitute Water Supply Plan because both wells will draw water out of Area A of their District. 7. Effect on Groundwater and Aquifer Recharge Areas The Cerise mining operation will be conducted above the water table. Consequently, the mine is projected to have negligible impacts on groundwater resources in the area. The site hydrogeology indicates that no existing permitted private wells would be significantly affected by the mine operation. All project surface flows, including additional flows from the proposed project, will be directed Impact Analysis Major Impact Review Application Page 3 of 5 to the detention/tailings pond which will allow for infiltration of the water. Discharge to the neighboring waterbody (Crystal Creek) is not needed as the pond will be large enough to capture and detain the flows. The Cerise Mine site is located outside of the floodplain and floodway of the Roaring Fork River. The mine site is separate from the river and floodplain by both Highway 82 and a berm that is over 100 feet higher than the Roaring Fork River Base Flood Elevation (BFE) based on the FEMA Flood Insurance Rate Mate for Garfield County, CO (unincorporated areas) Community Panel 080205 1880B. Crystal Creek is a smaller stream that runs along the western border of the mining site. This creek is not included in the FEMA mapping for the area. However, the river is over 25 feet lower than any adjacent mining activity and over 60 feet from the closest grading extents. There will be no mining in the floodplain of the creek, which has a 100 -year discharge of approximately 300 cfs. The water leased from the Basalt Water Conservancy District will be used as makeup credits for the water removed from the ground water system by the Cerise Mine. The Cerise Mine will automatically be covered by the Basalt Water Conservancy District's Substitute Water Supply Plan because both wells that they will use to draw water out of the groundwater aquifer are located in Area A of the District. The Cerise Mine is not in close proximity to a public sewer system. Therefore, the restroom facilities in the office will be tied to an individual septic disposal system (ISDS) and port -a - potties will be provided on the site for employees to use. The proposed ISDS has been designed by an engineer licensed to practice in Colorado. The system was designed to meet CDPHE requirements and it has been placed on the site to meet the locational requirements of the Water Quality Control Commission so that groundwater is not affected. 8. Environmental Effects a. Determination of the long term and short term effect on flora and fauna. There will be no significant long term or short term effect on flora and fauna as there is no Federally designated critical habitat for vegetative or wildlife species in the Cerise Mine Permit area. For more details, please see the Natural Habitat Statement (Section 23 of the application). b. Determination of the effect on significant archaeological, cultural, paleontological, historic resources. There will be no significant effect on archaeological, cultural, paleontological or historic resources as a result of mining the Cerise property. For more details please see the Report on Class I Cultural and Paleontological Resources provided in Section 18 of the application. Impact Analysis Major Impact Review Application Page 4 of 5 c. Determination of the effect on designated environmental resources, including critical wildlife habitat. 1) Impacts on wildlife and domestic animals through creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions. The Cerise Mine will have a minimal effect on environmental resources due to the fact that the area of disturbance is currently used for agricultural purposes and therefore does not provide optimal wildlife habitat. No hazardous attractions will be created on the mine site, the existing vegetation will eventually be replaced at the time of reclamation, and no significant migration routes will be disrupted by the mine For more details, please see the Natural Habitat Statement (Section 23 of the application). d. Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departments. There are no potential radiation hazards associated with the Cerise Mine. e. Spill Prevention Control and Counter Measures plan, if applicable. A Spill Prevention Control and Counter Measures Plan is provided in Section 27 of the application. 9. Traffic A detailed traffic study for the Cerise Mine is provided in Section 22 of the application. In addition, additional information regarding the traffic study findings as they relate to impacts on the County Road system can be found in the Narrative (Section 9 of the application) in response to Sections 7-108 and 7-840,E of the Code. 10. Nuisance The Cerise Mine will meet all County, State and Federal requirements pertaining to the generation of vapor, dust, smoke, noise, glare, vibration or other emanations. For specific details, please refer to the following documents: • Section 9: Narrative (specifically, please see responses to Sections 7-840, B, C and D of the Code) • Section 20: Air Quality Information • Section 21: Noise Analysis 11. Reclamation Plan Following mining the Cerise Mine site will be reseeded with pasture grasses so that the land can be used to pasture horses as desired by Clifford Cerise Ranch Co, LLLP, the landowners. Please see the Landscape Plan map in Section 13 of the application for details regarding the Reclamation Plan. Impact Analysis Major Impact Review Application Page 5 of 5 LAFARG E NORTH AMERICA MINING SITE Cumulative Impact Analysis Site Plan Maps PREPARED fOR Lafarge West, Inc. November 2010 Cumulative Impact Analysis Site Plan Maps Following are a series of seven Cumulative Impact Analysis Site Plan Maps that show the existing conditions with mining in the area and illustrate how the Cerise Mine and Blue Pit are projected to progress in relation to one another and impact the area. It should be noted that the timeline information presented on the maps is approximate and may change depending on future market conditions. In addition, all of the information presented regarding the Blue Pit is based on our understanding of their project and what was approved by the Board of County Commissioners for their expansion. What the maps show is that for 90% of the time that the Cerise Mine and Blue Pit are operating, together they will disturb less acreage than is currently disturbed by mining in the area. The other 10% of the time (2 years), the area of combined disturbance will be the same as the amount of land currently disturbed by mining in the area. Below is a brief explanation of the information shown on the seven maps. Existing Conditions Lafarge currently operates the 66± acre Powers Pit on the northwest corner of Highway 82 and County Road 103 (Crystal Springs Road). The Cerise Mine site is on the other side of County Road 103, across the street from the Powers Pit. Western Slope Aggregates is currently mining the Blue Pit; based on the aerial photography, they have currently disturbed approximately 53± acres of land for their mining operation. Therefore, a total of 119± acres of land in the area is currently disturbed for mining Cerise Mine Phase 1 • Blue Pit Area 1 By 2012, Lafarge will be finished mining the Powers Pit and they are required to have all of the reclamation site work completed and will be working on establishing vegetation on the site. Since mining operations will be completed at the Powers Pit, Lafarge wants to begin mining Phase 1 of the Cerise site in 2012 and they anticipate the first Phase will take a couple of years. During this same time, it is anticipated that Western Slope Aggregates will complete the mining of their Area 1. Between the two mines, we estimate approximately 43± acres will be disturbed in the Cerise Mine and 53± acres will be disturbed in the Blue Pit for a total disturbance area of just 96± acres. Cerise Mine Phase 2 • Blue Pit Area 2 The period of time when we anticipate Cerise Mine and Blue Pit will have the largest amount of land disturbed for mining will be from approximately 2014-2021. During this time, Lafarge anticipates that they will be mining Phase 2 of the Cerise Mine which will disturb no more than 55± acres. Western Slope Aggregates anticipates they will be mining Area 2 of the Blue Pit so we estimate up to approximately 64± acres of land will be disturbed. This means that we expect the total area of disturbance for mining operations in the area will be no more than 119 ± acres which is the same amount of land currently disturbed by mining in the area (see Existing Conditions map). During this point in time, the disturbed areas in the two mines will be a little over a 1/4 mile apart. Cerise Mine Phase 3 • Blue Pit Area 4, Phase 1 It is anticipated that between 2021 and 2023 the Cerise Mine will move into Phase 3 of their mining operation at which time they will be moving their aggregate plant to the floor of the mine to help Cerise Mine Major Impact Review Application minimize impacts on surrounding properties. At this point, some of the edges of the Phase 2 portion of the Cerise Mine will be reclaimed to 3:1 slopes and reseeded. The Blue Pit is expected to be operating in their Area 4, Phase 1 and it is our understanding that their plan is to reclaim as they proceed so their Area 2 is shown as being reclaimed. The disturbed areas in the two mines will be approximately 760± feet apart. Between the two mines, we estimate approximately 57± acres will be disturbed in the Cerise Mine and 52 ± acres will be disturbed in the Blue Pit for a total disturbance area of 109± acres. Cerise Mine Phase 4A • Blue Pit Area 4, Phase 2 The Cerise Mine and Blue Pit will be the closest together for just a couple of years between approximately 2023 and 2026. During this time, concurrent reclamation will continue to occur at the Cerise Mine and Blue Pit. Between the two mines, we estimate up to approximately 60± acres will be disturbed in the Cerise Mine and 52 ± acres will be disturbed in the Blue Pit for a total disturbance area of 112± acres. Cerise Mine Phase 4B • Blue Pit Area 4, Phase 3 From approximately 2026 until 2027 Lafarge will be in the final stage of mining Cerise and the Blue Pit will be mining Area 4, Phase 3. The spacing between the two disturbed areas is back to being 760± feet apart. Once again, concurrent reclamation will be happening at the Blue Pit and Cerise Mine. Between the two mines, we estimate approximately 60± acres will be disturbed in the Cerise Mine and 52 ± acres will be disturbed in the Blue Pit for a total disturbance area of 112± acres. Cerise Mine Reclamation • Blue Pit Area 4, Phase 2 It is expected that Lafarge will begin final reclamation of the Cerise Mine in approximately 2027 and have reclamation complete by 2029. During this same time, Western Slope Aggregates will be mining Area 4, Phase 4 of the Blue Pit and concurrently reclaiming Area 4, Phase 3. Therefore, all 65± acres of the Cerise Mine will be in the process of reclamation and only the Blue Pit will be mining and have approximately 52± acres disturbed.
