• As the first phase of the refuse pile is nearing completion, the next section of the <br />foundation will be cleared of all vegetative or organic material. Topsoil will be <br />salvaged and temporarily stockpiled. Alluvial material will be excavated and <br />placed at a thickness of 42-inches on the completed portion of the refuse pile <br />with excess material placed in the coverfill pile. Topsoil will be obtained from the <br />temporary stockpile and placed on the completed portion of the refuse pile to <br />provide the required 4 feet of non-toxic cover. <br />Thus, the waste pile will be covered with 4-feet of non-toxic cover as <br />contemporaneously as practicable. Final reclamation will include completion of <br />the cover material including topsoil and construction of the permanent diversion <br />and collection ditches. Revegetation will be in accordance with Section 3.9.6. <br />The seed mixture(s) will be drilled on level areas and on slopes which will permit <br />machine work along the contour. On slopes which prevent safe or adequate <br />machine work, the surface will be hydroseeded or broadcast seeded. Broadcast <br />seeding will also be used for small isolated areas. Dozer tracking up and down <br />steep slopes or other roughening techniques will be used before seeding to <br />• establish a better seedbed. On predominantly south and west facing steep <br />slopes, the surface will be extensively roughened to provide for increased <br />moisture retention and favorable 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. On drilled <br />sites the hay or straw will be crimped with a serrated disc or other appropriate <br />equipment. On steeper slopes and areas where crimping is not feasible, straw or <br />hay will be anchored down using a tackifier, netting, or a tackifier mixed with <br />wood or wood/paper fiber. The tackifier will be applied in accordance with <br />manufacture's specifications with consideration of the type and quantity of mulch <br />applied, slope, soil conditions and other applicable factors. <br />M" 2.2-12ii 6/02 <br />
