Benson Brothers Pig Mesa Pit <br />DMG 112 Application <br />Exhibit E- Reclamation Plan <br />Material handled on site will not create an unauthorized release of pollutants to the <br />surface drainage system. A Stormwater Dischazge Permit for Gravel Mines will be <br />obtained from the Colorado Department of Health. <br />No Pollutants will be dischazged to groundwater on this site. <br />3.1.6 This is a dry pit. There will be no disturbance to the prevailing hydrologic balance. <br />There aze no wetlands on this site. Topsoil and overburden stockpiles and berms will <br />be stabilized by broadcasting with a grass seed mix as recommended by the Natural <br />Resources Conservation Service, Delta Office. A Stormwater Discharge Permit for <br />Gravel Mines will be obtained from the Colorado Depaztment of Health. There will be <br />no dischazge of process water used in aggregate washing from this site. <br />3.1.7 We will not encounter any groundwater on this site. <br />3.1.8 There is very little evidence of any wildlife on this site. There aze no trees or shrubs or <br />any cover or feed for wildlife except reptiles, small rodents, and insects adapted to <br />desert environments. <br />3.1.9 Topsoil will be removed and stockpiled in the process and stockpile azea and protected <br />from erosion by broadcasting with 28 lbs/acre of Tall Wheatgrass and Tall Fescue after <br />October 15 as recommended by the NRCS Delta Office. <br />We do not expect to have to move the topsoil stockpiles until it is used in reclamation. <br />Topsoil will be replaced 3:1 slopes and on relatively flat sloping pit floor and <br />compacted with the placing equipment. These soils aze of poor quality and currently <br />support little vegetation which is one reason the reclamation plan does not include re- <br />vegetation. <br />Topsoil will be replaced at 4 to 8 inches. <br />3.1.10 Re-vegetation is not a part of this reclamation plan. <br />Spraying according to an approved Delta County Weed Mitigation Plan will control <br />weeds. <br />3.1.11 There aze no buildings or structures on this site and there aze no structures planned in <br />conjunction with this operation. <br />3.1.12 The operator will post the required sign at the entrance to the mine. <br />The boundaries of the affected azea will be delineated by existing fences or steel mazker <br />posts before mining begins. <br />d) Overburden will be used to create the process and stockpile azea by cutting and filling the shale <br />ridges and gullies on the northeast flank of the mesa. It will be stabilized by compaction with <br />the moving equipment. Excess topsoil and overburden will then be removed and stockpiled in <br />a berm along the northeast edge of the process azea, which will also serve as a sight and sound <br />barrier for the operation. Topsoil stockpiles will be stabilized by broadcasting the seed mix as <br />described in 3.1.9 above. Overburden will be accessible for backfilling and final grading as <br />needed. The topsoil will be spread after final grading of overburden. Re-vegetation is not part <br />of this reclamation plan. <br />e) Reclamation if this site will consist of reducing high-walls to 3:1 (h:v) and maintaining the pit <br />floor at or neaz final grade as mining progresses. The high-walls on the northwest perimeter <br />will be sloped as the mining east to west is completed and mining begins to move north to <br />south. High walls on the east and west will be reduced to 3:1 slopes concurrently as mining <br />moves to the south. A maximum of 1200 feet of un-reduced high wall will exist at any one <br />time. Topsoil will be replaced on 3:1 slopes as soon as the final slope is created. Topsoil will <br />
