The material removed from the pit will be hauled to a portable crushing and screening unit by the <br />frontend-loader as it is removed from the pit. This crushing and screening plant will size the <br />gravel material and direct it to stockpiles for reloading and hauling off-site. The screening and <br />crushing plant will be powered by a portable dieseVelectric generating set with a 350 - 500 gallon <br />fuel tank, positioned nearby. The operator has no plans for an office, but will have a truck trailer <br />converted to a material shed located neazby the crusher and material removal operation. A <br />portable sanitation facility ("porta-potti") will be located neaz the supply trailer. A 1500 - 2000 <br />gallon fuel storage tank for fueling equipment and the generator fuel storage tank will be located <br />in appropriate bermed and plastic lined containment. All of the above equipment is portable and <br />will be relocated (always kept on disturbed areas) as the mining face advances to reduce loader <br />cycle times and facilitate reclamation. <br />Any hazardous materials/petroleum products stored in the storage trailer will be stored in a <br />containment cabinet designed for the purposed of providing primary containment of spills. <br />The access road directs all truck traffic to the gravel pit along the southern edge of the permit <br />boundary and accesses County Road 37.00 approximately 1000' east of the mining boundary. <br />Overhead power lines cross the mining azea and are illustrated on the Exhibit C-1. San Miguel <br />Power Association maintains an easement for these structures. The operation will incorporate <br />measures to insure that the operation will not affect the stability of these structures. <br />The gravel deposit lies on a shale shelf. This shale layer is considered an impervious confining <br />layer which should keep the pit floor dry. At least 2-feet of porous material will be left over the <br />shale layer and under the topsoil to provide for drainage of any intercepted stormwater and for a <br />rooting zone for establishing vegetation during reclamation. If ground water is encountered, pit <br />floor projections will be revised to maintain a minimum of 2-feet of undisturbed material above <br />the ground water. <br />The only commodities to be mined aze construction materials. Construction materials include bu[ <br />aze not limited to pit run gravel, road base, and screened/sized gravel. No secondary commodities <br />are to be mined or extracted. <br />The construction products will be used for the production of asphalt, concrete and road <br />construction. Additionally, the gravel products aze used as select and special fill for large and <br />small construction projects. <br />Operating hours of [he pit aze controlled the Montrose County Special Use Permit. <br />12/02 D - 2 <br />
