Design Criteria <br />Topic <br />Design Criteria for the Proposed Action <br />_ <br />87. Stabilization of steep cut slopes that will remain unreclaimed over <br />a winter or longer will be stabilized through placement of native <br />boulders or other reclamation. <br />88. All cut slopes would be aggressively re- vegetated (hydro-mulch <br />seeded and fertilized, if necessary) following the completion of <br />construction to help stabilize these disturbed sites. <br />89. Post - construction seeding applications would continue until <br />determined successful by the Forest Service. <br />BMP <br />BMP, State <br />Forest Plan, <br />CO DRMS <br />Onsite Inspections <br />90. Prior to any construction, onsite inspections with appropriate <br />regulatory agencies will be held to discuss site - specific concerns. <br />36 CFR 228 E <br />OPERATIONS & MAINTENANCE ACTIVITIES <br />Emergency Shaft <br />91. Hoist and generator will be tested weekly per MSHA <br />requirements to assure functionality. <br />92. A 1,000 gallon propane tank for generator will be buried in pad. <br />93. The generator for shaft will be muffled to reduce noise during the <br />testing periods. <br />MSHA, MCC <br />Project Plan <br />MCC Project <br />Plan <br />MCC Project <br />Plan, State <br />Site Security <br />94. A 6 -foot high, locked, chain -link fence topped with barbed wire <br />will surround shaft escapeway to preclude wildlife and public. <br />95. Underground mine workings will supply power to light the shaft <br />and emergency escapeway instead of solar power to avoid <br />installation of a powerline. Back-up power will be provided by a <br />generator. <br />MCC Project <br />Plan <br />MCC Project <br />Plan <br />De -gas installation <br />96. Degassing trailer, if needed near shaft/escapeway, will be <br />enclosed with a fence with a locking gate to preclude public, <br />livestock, and wildlife entry. <br />97. Equipment will be inspected by MSHA prior to installation. <br />MCC Project <br />Plan <br />RECLAMATION ACTIVITIES <br />Closure <br />98. Shaft and emergency escapeway would be capped with concrete <br />and steel structure below ground surface and backfill material <br />would be used to cover the caps. Caps would consist of 6 inch <br />layer of concrete poured onto a steel screen supported by a steel <br />beam frame installed 10 feet below the ground surface. Concrete <br />collars would be removed and .the area re- graded to approximate <br />original contour and re- vegetated. <br />30 CFR <br />75.1711 <br />Reve getation <br />99. Subsurface ripping would be used to reduce compaction prior to <br />replacement of the topsoil and seeding. <br />BMP <br />Design Criteria <br />Topic <br />Design Criteria for the Proposed Action <br />
