Mud Creek Pit -Reclamation Permit Application -112 (C) Exhibits Page 21 of 67 <br />Holes, etc. <br />There are no drill holes, auger holes, adits or shafts to reclaim. <br />Maximum slopes <br />Slopes of 1V:3H or less, as proposed, are compatible with surrounding conditions and land use. See Table E-1 <br />Permanent industrial areas will either have slopes of 1 V:3H or less, or have retaining structures as needed. <br />Use of farm equipment <br />Slopes will be compatible with such use in the area. <br />Notice of other backfill <br />The Applicant will comply with this requirement to notify the Division if other backfill is used. Use of clean <br />construction debris, such as soil, subsoil, waste rock, overburden, clean Portland or asphaltic cement concrete <br />rubble or waste (as from washout of trucks), for backfill, to be covered by topsoil as appropriate for intended <br />post-mining use, is proposed. Noacid-bearing materials, tailings, or other toxic or potentially toxic materials <br />shall be used. When in doubt, standard characterization methods shal- be used to evaluate the suitability of <br />construction/demolition debris-type materials for use on site. Records of off-site sources of backfill material shall <br />be maintained for the life of the operation. <br />Prevention of unauthorized release of pollutants to surface water <br />The Applicant will handle mined material to be disposed of on-site in a way to prevent unauthorized release of <br />pollutants to surface water, and comply with this requirement, <br />Prevention of unauthorized release of pollutants to groundwater <br />The Applicant will handle material mined, handled, or disposed of on-site in a way to prevent unauthorized <br />release of pollutants to groundwater, and comply with this requirement. <br />General water hydrology and water quality <br />Hydrology and water quality issues are addressed at length in Exhibit B. The Applicant will comply with <br />applicable water and water rights laws and regulations, and water quality laws and regulations. No dredge or fill <br />in waters of Colorado or the United States is proposed, and no temporary or large siltation structures will be <br />placed except as required by permits,9 and will be removed in accordance with those permits. <br />Earth dams <br />Mining will be done only in areas which will not present potential for negative impact on the stability of off-site <br />earth dams (located near NE corner). Except for storm water control systems and ponds for livestock use, there <br />will be no earth or other dams or basins constructed. Those bermed areas and basins will each contain less <br />than 10 acre-feet of water and with a total depth of less than 10 feet at any time, including immediately following <br />24-hour, 25-year storm events, and are therefore non-jurisdictional. Mining is expected to remain well above the <br />normal ground water table. Rock check dams and incised basins shall be used for sediment and erosion control. <br />Erosion control <br />All surfaces will be stabilized and protected to control erosion. Stockpiles of soil and excess fines will be <br />protected against erosion, traffic, and weed invasion; either by seeding (temporary seed mix or agricultural <br />products) or application ofdust-control and crusting agents (such as polymers or other soil treatments), wind or <br />silt fencing. (See Exhibit B for seeding data, Exhibit C for additional stockpile information.) <br />9 Primarily CDPS storm water permits. <br />McStone Aggregates, LLC 15 FEB 2008 ©WAST`EL1NE, INC 2008 PN 5006.1-4(009) <br />
