The Divisions policy concerning the bedrock Mancos Shale and the selenium concerns are <br />understood by the applicant. The applicant will leave a minimum of two (2) feet of undisturbed <br />material above the Mancos Shale bedrock. All topsoil will be reserved at the site for reclamation <br />activities. No topsoil will be removed from the site. <br />The buffer zones along the west and north sides of the proposed area of operations will be used for <br />brash pile habitat and temporary topsoil stockpiling and thus will be disturbed areas. The interior edges <br />of these 50-foot perimeter buffer areas will be graded to match the reclaimed slope. The buffer zone <br />area for [he wetland is a Vue buffer zone and will have no disturbance. The silt fencing will separate <br />this buffer area (and the wetlands below it) from all active site areas. In the southwest comer of the <br />17.74 acre Phase I area, a combination of additional silt fencing, bales, and/or and berms will be used <br />as necessary during mining and reclamation activities in [his area. In the 16 acre Phase 2 area all <br />mining will take place above (north) the interior haul road. <br />The silt fence will separate the buffer zone and wetland from [he access road area and active areas of <br />the site. The buffer zone will remain undisturbed. The access road will have sufficient drainage and <br />berms to allow for storm runoff and sediment retention A ditch will be constructed along the north <br />side of the access road to contain and direct mnoff away from the wetland area. Straw bale filter <br />structures will be used along with additional silt fence along the access road and in the active mining <br />areas as necessary to keep sediments from entering the wetlands area. USACOE recommendations <br />have been followed for the construction of the stream crossings (CMP installations) and for the <br />rehabilitation and protection of the wetland area. <br />Sloping, final grading and topsoil placement and seeding activities will be done concurrent with <br />mining activities a[ the site whenever possible. If topsoil stockpiles are to be left for more than 1 <br />growing season, [hey will be seeded with the USDA recommended seed mix via broadcast method. <br />The permit area and [he phase areas will be marked and staked using steel posts and other delineation. <br />Mining will be done with dozers, front end loaders and excavators. Gravel and cobble deposits will be <br />facially removed from [he ridges for loading, hauling and processing. Gravel will be loaded on dump <br />trucks with rubber tired loaders and hauled offsite or temporally stockpiled for later hauling. A <br />crusher/screen set up may be onsite periodically to process material for hauling and/or project <br />stockpiles. An asphalt plant may be onsite occasionally if the operator secures contracts for asphalt <br />production. The crusher/screen spread and asphalt plants are not permanently installed at [he site and <br />anticipated operations would be from 4 [0 12 weeks at a time on an as needed basis. Secondary <br />containment for site hazardous materials lie. temporary fuel and lubricants for mobile process <br />equipment) will be constructed. Containment will generally consist of a bermed enclosure of sufficient <br />volume surrounding the temporary site fuel storage/materials area and containers/tanks. The location <br />of the temporary enclosure will move as mining and reclamation activities proceed across the Phase <br />Areas from mobilization to mobilization of contract equipment or spreads to the site. I[ is anticipated <br />that several mobilizations of contract process equipment will occur during the period of mining <br />activities at the site. Other than the bermed area, volumes of fuels and other lubricants and/or <br />hazardous materials, as previously stated, will he [hat volume contained in the tanks and reservoirs of <br />each separate equipment type. <br />Following the extraction of all aggregate material, the site will be graded to a uniform slope from north <br />to south and covered with the stockpiled topsoil. The slope will [hen be re-vegetated with the Soil <br />Conservation Service's recommended grass and shmbs to a final use as rangeland. The entire Phase l <br />Area will be mined and reclaimed prior to moving into the Phase 2 Area. Some disturbance will occur <br />in the Phase 2 Area during Phase 1 operations along [he haul/access road where temporary product <br />stockpiling may be located. This disturbance will be less than I acre and will lie along the "old stage <br />road trace" which is adjacent to [he haul road. Vehicle, haul truck and equipment speeds will be ISmph <br />or less on the haul road. The haul road will remain as a farm road for the landowners use after mining <br />and reclamation activities at the site are completed and will no require reclamation. <br />
