Mr. Paul E. Thomsen - 3 - July 14, 1993 EXHIBIT E - Reclamation Plan (continued) 5. Mountain mahogany provides cover over most of the current permit and proposed amended acreage while providing excellent browse for def~r. The Division requests a commitment to seed random patches of mountain mahogany over twenty-five percent of the tree pad surface. Please provide pounds PLS per acre. (Mountain mahogany cannot be seeded with the grass seed mixture because of competition and so must be seeded alone in patches.) 6. Areas that will not require pad construction but will be affected by mining activities such as exploration, drainage control, etc. or where mining interfaces with undisturbed natural drainages will require seeding with an approved seed mix. Please state your commitment to seeding these areas. 7. Please comment on mulching of the pads and fertilizing as part of the Reclamation Plan. The Division requests a commitment to test the final growth medium to determine nutrient requirement and application prior to seeding. 8. The Reclamation Plan states that drainages will be maintained and the runoff characteristics of the area will be virtually identical to the existing characteristics. Exhibit C Pre-mining and Mining Plan Mtip indicates that the natural drainages between pods in Phase 2 will not be disturbed by mining. Erosion control devices such as check dams Mill be necessary on these drainages that lie downslope of both Phase 1 and 4. How will the natural drainage that lies at the north end of Phase 5 be maintained? Please discuss. 9. Please indicate which haul roads or portions of haul roads will be reclaimed and which roads will remain as service roads. Roads for all phases should be addressed. 10. Because of the experimental nature of the proposed Reclamation Plan, the potential erosion hazard both on and off-site due to increased run-off from the exposed sandstone slab., and the potentially extended time period necessary to obtain an effective cover over the pads and to trap fines on the rock piles, the Division recommends the following: a. That the financial warranty be based on total acres to be af~-ected by all mining activities within a phase or phases, but that b. Acres of maximum disturbance (exposure of sandstone slabs or equally difficult terrain where pads will be constructed) be limited. This acreage maximum would be based on adequate si::ing of erosion control structures and the commitment that reclamation would proceed on these acreages before additional bare slab could be exposed. Please commit to a maximum acreage that will be disturbed prior to reclamation beginning on the mine. Such maximum acreage cannot be more than is reasonably required for operations and stockpile areas.
