• The top of the pile will be sloped back to the south to ensure run-off from the fill <br />surface flows to the collection ditches and is not allowed to flow over the outslope <br />of the fill. As the pile increases in size, a refuse slope will be constructed above <br />the reclaimed lower slopes. A silt fence will be installed immediately above the <br />reclaimed slopes to assure it is not contaminated with refuse. The design of the <br />silt fence is presented in Appendix~M(vii) at page 44. <br />Large rock (18" to 30" diameter) obtained from the cover material will be <br />segregated and distributed on the completed slopes following topsoil placement <br />to provide for small animal habitat and blend more closely with the adjacent <br />slopes. Placement will be random with spacing varying from 50-feet to150-feet. <br />Final reclamation will include completion of the cover material including topsoil <br />and construction of the permanent diversion and collection ditches. <br />Revegetation will be in accordance with Section 3.9.6. <br />The seed mixture(s) will be hydroseeded or broadcast seeded. Seedbed <br />preparation for all disturbed areas shall consist of extensive roughening by track <br />• hoe gouging (pocking) or other preparation technique approved by the BLM. <br />Extensive roughening provides for increased moisture retention and favorable <br />micro sites for plant establishment. <br />All seeded areas will be mulched with certified weed free grass hay or straw. <br />Approximately two tons of mulch will be used on each acre seeded. Straw or hay <br />will be anchored using a tackifier, netting, or a tackifier mixed with wood or <br />wood/paper fiber. The tackifier will be applied in accordance with manufacture's <br />specifications with consideration of the type and quantity of mulch applied, slope, <br />soil conditions and other applicable factors. <br />Inspection <br />The waste rock disposal area will be inspected for stability on a quarterly basis <br />by a qualified engineer. In addition the area will be inspected during the following <br />critical periods: removal of all organic material, large boulders and topsoil as <br />previously described, installation of surface drainage systems, placement and <br />compaction of fill materials, and during revegetation. A report will be provided to <br />. the Division by the inspecting engineer within two weeks of the completed <br />inspections. A copy of this report will be kept at the mine site. <br />M" 2.2-12v 10/02 <br />
