EXHIBIT D (Amended) <br />Powderwash Pit No. 66 - Mining Plan <br />(Permit M-2006-006 Am 001) <br />The Powderwash Pit No. 66 is a proposed sand and gravel pit on County Road No. 66 <br />approximately 4 miles cast, and 5 miles south of the Powderwash housing community. The pit <br />will be located in the Sl/2 of Section 25, T11N, and R97W of the 6th P.M, Moffat County, <br />Colorado. The purpose of this mine is to replace the Powderwash Pit #19, which was 4 miles <br />south of Powderwash. The project is on the Smith Rancho land (with no federal minerals) and <br />will provide pit-run and road-base materials for county roads in the area. The only man-made <br />improvements are Moffat County's highway No. 66 and No. 6613, and an access trail to the <br />BLM as shown on Exhibit C-3. Moffat County might relocate one, or all, of these roads to <br />accommodate the mining program, if necessary, but it is likely that the gravel reserves in <br />Mining Zone # 1 & 2 will provide sufficient gravel resources for a 20 year life of the mine. <br />Moffat County will not obstruct the legally acquired access across the project site. <br />The significant disturbances will be limited to the mining, storage and removal of the surface <br />minable materials on the permitted area. No off-site facilities will be involved. If it is <br />practical, Moffat County will protect the integrity of the dry wash running north along the <br />center of the project; however, we will mine out the resources beneath the dry wash if they <br />are substantial. The Corps of Engineers will require a 404 permit for any culvert, or other fill <br />material to the natural drainage. The Stormwater Drainage regulations require an operator to <br />contain the stormwater within the mine area; we intend to develop basins within the mining <br />area to prevent runoff from entering State and Federal waters. If these low areas tend to <br />impound significant amounts of water, Moffat County will notify the surface owners of the <br />water status, and will suggest that they file for storage right under Colorado water law. <br />The topsoil depth is from 6 to 12 inches throughout the affected area. This humic material will <br />be stripped and stockpiled in an inactive portion of the affected area, and it will be protected <br />from the drainage channels until needed for reclamation. The topsoil piles will be protected <br />from other stored materials. Seeding them with Moffat County's seed-mix and application <br />formula will stabilize the topsoil piles. Signs will be placed to identify the topsoil and to <br />caution not to remove. The road base stockpiles will be protected from erosion and they will <br />be identified and kept separate from other stockpiled materials. Moffat County will identify <br />and stabilize overburden stockpiles in the same manner if they are to be stored for more than a <br />year. <br />Surface mining may occur anywhere on the project, but we intend to begin operations in <br />either of the two mining zones as shown on the Mining Plan Map. There are two mining <br />procedures; in the first procedure the operator will use 5-yard front-end loaders to excavate <br />along a vertical face, and to transport the material to the crushing and screening- <br />Exhibit D (page 1)
