EXHIBIT D State Pit No. 38 (Mining Plan) Note: This Exhibit D has been mod f ed by clan Eying the term "stabilize" as it applies to overburden stockpiles. The State Pit No. 38 is a proposed sand and gravel mine on the paved Moffat County Highway No. 4 -approximately 5 miles northeast of the Eddinger Bridge crossing the Little Snake River (see Exhibit B-2). The center of the affected area will be located in a portion of State Tract No. 38, which is also described as Lot IS (NWl/4SE1/4) of Section 36, T12N, R95W of the 6a' P.M., Moffat County, Colorado (see Exhibit A-4). The purpose of the mine is to provide road construction materials for the development and maintenance of several county roads in that vicinity. The only man-made improvements that may have a "defined current and recognizable value of an economic nature" on, or within 200 feet of, the affected area are (1) the main access road from County Road No. 4; and (2) a primitive access trail to the BLM land north of the project as shown on Exhibit C-3. There is an abandoned four-acre well- drilling pad on Moffat County's State Lease #GP 3440 that does not have a defined, current and recognizable value of an economic nature. Moffat County will mine and reclaim the abandoned well-pad structures along with the other affected areas of our permit (see Exhibit D-1). The significant disturbances will be limited to the mining, storage and removal of the road construction materials, including sand, clay and gravel products; no off-site facilities will be involved. If it is practical, Moffat County will protect the integrity of the Stormwater drainage basin running north through the center of the affected azea, however, we will mine-out the gravel resources beneath the dry wash if they are substantial -subject to the applicable permit requirement within the jurisdiction of the Army Corps of Engineers. The Stormwater Drainage regulations require an operator to prevent Stormwater from entering the mining area; and to prevent discharging water into the natural drainage without first developing berms, ditches and basins to settle out the suspended solids. If low areas tend to impound significant amounts of water, Moffat County will notify the surface owner of the water status, and will suggest that they file for a water storage right in order to put the water to a beneficial use. The topsoil depth is from 6 to 10 inches throughout the affected area. This dark organic topsoil will be stripped; the stockpiles will be stored in an inactive portion of the affected area, and they will be protected from the drainage channels until needed for reclamation. The topsoil piles will be protected from other stored materials. Seeding them with Moffat County's seed-mix formula will stabilize the topsoil piles -and signs will be placed to identify the topsoil and to caution against removing it. The crushed road-base stockpiles will be identified, protected from erosion, and kept separate from other stockpiled materials. Moffat County will stabilize overburden stockpiles if they are to be stored for State Pit No. 38 -Moffat County Road Deparunent
