i~ <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 to <br />provide for small animal habitat and blend more closely with the adjacent slopes. <br />Placement will be random with spacing varying from 50-feet to150-feet. <br />Rock may be stockpiled to the east of the active coal mine waste disposal area <br />as long as the rock stockpiles are within the area that will ultimately be disturbed by <br />disposal area expansion. Topsoil will not be salvaged prior to stockpiling rock <br />associated with Phase I waste disposal development, but topsoil will be salvaged from <br />areas to be affected by expansion of rock stockpiles or new rock stockpiles associated <br />with subsequent phases of waste disposal area development. The rock storage area <br />where topsoil was not salvaged is within the sediment controlled area and_impact to the <br />topsoil horizon is minor. The only impact to the topsoil is minor compaction which will <br />be relieved as it is salvaged for placement on completed portions of the coal mine <br />waste disposal area. Access to and from the rock stockpile will be very infrequent and <br />only allowed when topsoil is dry and firm. <br />Final reclamation will include completion of the cover material including topsoil <br />and construction of the permanent diversion and collection ditches. Revegetation will <br />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 hoe <br />gouging (pocking) or other preparation technique approved by the BLM. Extensive <br />roughening provides for increased moisture retention and favorable micro sites for plant <br />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 will <br />be anchored using a tackifier, netting, or a tackifier mixed with wood or wood/paper <br />fiber. The tackifier will be applied in accordance with manufacture's specifications with <br />consideration of the type and quantity of mulch applied, slope, soil conditions and other <br />applicable factcrs. <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 critical <br />periods: removal of all organic material, large boulders and topsoil as previously <br />described, installation of surface drainage systems, placement and compaction of fill <br />materials, and during revegetation. A report will be provided to the Division by the <br />inspecting engineer within two weeks of the completed inspections. A copy of this report <br />• will be kept at the mine site. <br />MR-22 2-18 05/05 <br />
