Alternatives <br />Table 2-2 <br />Design Criteria <br />Topic Design Criteria for the Proposed Action <br /> and located in areas where disturbance by ongoing mining operations will be <br /> minimized. Such stockpile areas must be included in the affected areas and subject to <br /> all reclamation requirements. <br /> Immediate seeding of topsoil stockpiles for the purpose of stabilization may be <br /> required. <br /> Once stockpiled, the topsoil shall be handled as little as possible until replacement on <br /> the regraded, disturbed area. <br /> The Operator shall take measures necessary to assure the stability of replaced topsoil <br /> on graded slopes such as roughing in final grading to eliminate slippage zones that <br /> may develop between the deposited topsoil and heavy textured spoil surfaces. <br /> When growing media is replaced, it shall be done in as even a manner as possible. <br /> Fertilizer or other soil amendments shall be added, if required in the Reclamation <br /> Plan. <br />Subsoil Minimize footprint of stockpile to limit disturbance. Use for regrading and <br /> contouring. <br />Erosion & Sediment Erosion will be minimized through interim reclamation including, but not limited to, <br />Control contouring, seeding and mulching. <br /> Sediment control measures such as, but not limited to, silt fence, straw mulch, site <br /> containment and sediment control ponds will be utilized as needed. <br /> Construction on steep slopes would be fully designed and engineered according to <br /> Forest Service standards and design criteria and should include an erosion control and <br /> maintenance plan. <br />Geologic Hazard Leases contain stipulations restricting occupancy in areas of geologic hazards: Avoid <br /> areas with high geologic hazards to prevent mass slope failure in Section 32, T13S, <br /> R90W, 6th P.M. unless specifically approved by authorized officer.* <br /> Controlled Surface Occupancy Stipulation. Areas with moderate geological hazards <br /> will require analysis and mitigation plans detailing construction and mitigation <br /> techniques to ensure stability of facilities in portions of Sections 27-29 and 32-34, <br /> T13S, R90W, 6th P.M. and Sections 3-4, 9-10, T14S, R90W, 6th P.M. unless <br /> specifically approved by authorized officer.* <br /> No Surface Occupancy Stipulation- No operating on slopes greater than or equal to <br /> 60% or areas surrounded by slopes greater than or equal to 60% to prevent erosion, <br /> mass failure and loss of productivity in portions of Sections 27-29 and 32-34, T13S, <br /> R90W, 6th P.M. and Sections 3-4, 9-10 T14S, R90W, 6th P.M. unless specifically <br /> approved by authorized officer.* <br /> Controlled Surface Use Stipulation Surface use on slopes 40-60% will be subject to <br /> analysis and mitigation plans detailing construction and mitigation techniques to <br /> minimize potential for soil loss, mass land movement, revegetation failure and <br /> unacceptable visual impairment except as otherwise approved by authorized officer. <br /> This may apply to lands in portions of Sections 27-29, 32-34 T13S, R90W, 6th P.M. <br /> and Sections 3-4, 9-10, T14S, R90W, 6th P.M.* <br />Incidental Coal Any coal recovered incidental to project will be taken back to the mine site or <br />Recovery disposed of in the mud pits. <br />' Deer Creek Ventilation Shaft and E Seam Methane Drainage Wells DEIS 27 <br />
