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 Ions of aggregate per year for a total of up to 7,280,000 tons by the time reining 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 he 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. BOCC 1 1 CV214 - 000001 TETRA TECH Page 2of5 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 liming 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 an 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 aur understanding that they will be concurrently reclaiming as they move forward with mining so as 10 minimize their impact on the area. We anticipate that there will be a 21 year period of time that the Cerise Mine and Blue Pit will be adjacent to eachother (approximately 2027-2429). However, the area in which they are adjacent to eachother is as far south as possible, awayfram 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 an pages 35 to 39 of the Narrative in response 10 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 Co, 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 Chord Cerise Ranch Company, 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 10 lease Lafarge water, is also included in Section 16 of the application. BOCC 1 1 CV214 - 000002 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. 1f the life of the gravel operation is longer than one year, then the County directs Applicants to provide a permanent, reliable potable water system. 1 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. Sec 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. 1 strongly encourage you to investigate other options for waste water such as an I S DS. 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, porta potties will 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 /SDS 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 A thorough response to Section 7-105 is provided in the Narrative (Section 9 of the application).

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 coccal 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 2810 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 Germing, 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 gel BOCC 1 1 CV214 - 000004 TETRA TECH Page 5 of 5 Ms. Molly Orkild-Larson November 19, 2010 a realistic view of what will he seen. As expected, the model shows that the entire site is not screened; however, 11 also shows that the screening and berrning 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.
