directed off any highwall into them ine. Excepting the highwa It, slopes in the area of <br /> drainages will be maintained at or shallowerthan 3H:1 V. As no stormwaterwill leave or is <br /> anticipated to leave the site, a CDPHE Storm Water Discharge permit is not required. <br /> 4. Topsoil and Overburden Handling Topsoil will be salvaged from the mined area and <br /> placed in a stockpile in the northwest extent of the site. Piles are shown at the perimeter of <br /> the permit boundary on Map E-2,the maximum disturbance limit. Topsoil stockpi Les will be <br /> created by stripping them in imum required disturbed area for that phase of mining.Topsoil <br /> is expected to range from 0-4 inches.The topsoil berm will be used during reclamation, will <br /> be constructed to 2H:1 V slopes or shallower, and will be seeded within 180 days of pile <br /> establishment with native rangeland grasses to stabilize the topsoil stockpile until <br /> reclamation is in process. Variably thick overburden will be handled in the same fashion <br /> throughout the mine's life as topsoil detailed above. <br /> 5. Schedule of Operations Mining and processing will be conducted with portable <br /> equipment at various times of the year. Mining operations will bed ictated by initial <br /> recovery values and market conditions. Mining may take ptace 7 days per week. Night <br /> mining willnotoccur, although minor truck activity or repairs may occur after daylight <br /> hours. <br /> 6. Montrose County Impacts and Environmental Impacts The impacts to Montrose County <br /> will be limited. No dust is expected from the operation as the active mine area and roads <br /> are watered as needed. In the event that airborne dust is observable, immediate action to <br /> mitigated ust via roadway wetting and a slowdown of production wilt be initiated and <br /> 7 <br />
