Storm water diversion and sediment control structures will be put in and remain in place <br />until the regraded backfilled or regraded disturbed areas are top soiled/subsoil, and revegetated (Rule <br />3.1.5(3)). <br />Graded slopes will be less than 2(Horizontal 11-11)• I(Vertical IVl) -the post mine topography will blend in <br />with existing topography- op soil will be placed where deemed possible and revegetated. If soil or <br />alternative growth medium is not available from borrow areas onsite, subsoil will be used with <br />amendments or soil will be brought in from offsite. Soil or subsoil will only be borrowed from the site <br />within the permit area adjacent to existing disturbed areas where the soil depth is greater than six inches <br />and when approval from the Division has been obtained (Rule 6.3.4(1) (b)). <br />All manmade mining and milling structures will be salvaged or removed, and buried at the portal, <br />underground disposed offsite in an approved land fill or recycled. The disturbed areas will be graded, top <br />soiled to a depth of six inches, mulch applied and revegetated as outlined in this section. <br />Mayday portals will be appropriately backfilled with crushed rock, sloped and closed in accordance with <br />DRMS requirements. The portals will be barricaded or collapsed. Mine rock will be backfilled on the <br />existing bench such that the mine portal is buried under 5 feet of cover and graded with slopes equal to or <br />less than 2(H): 1(V). (Rule 3.1.5 (7)). The mill site will be sloped, graded and reclaimed in accordance <br />with the guidelines outlined in this section where slopes will be equal to or less than 2(H): 1(V) (Exhibit <br />E-7). Slopes will be graded to conform to existing topography (See Exhibit D-1). (Rule 3.1.5) Slopes will <br />be graded to existing or geotechnical stable slopes or less as depicted on Exhibit D-2 (Mayday No. 1) and <br />Exhibit D-3 (Mayday No. 2)(Rule 6.3.4(1)(b) ) <br />Groundwater and surface water quality will be analyzed during and after reclamation activities to <br />document and to demonstrate compliance with existing surface and groundwater quality guidelines <br />established by the Colorado Water Quality Control Commission (WQCB). <br />Pre-existing mine roads outside of the Mayday permit area will not be reclaimed, graded or revegetated. <br />(Exhibit E) (Access Roads are identified in Exhibit C) (Rule 6.374(1) (d)) <br />Revised March 30, 2010 Amendment M-1981-185 <br />"Strategically Positioned - Technically Prepared" <br />9034 E Easter P1 Suitc 201, Centennial, Colorado 80112, p: (303) 832.7664, f: (303) 832-7469
