No topsoil was stripped prior to the initial mine bench and access road development. Topsoil was <br />stripped in association with initial phase development of the coal waste disposal area in 2004. <br />Subsoil was also salvaged and separately stockpiled for use as non-toxic refuse cover. Two small <br />additional soil stockpiles were present in the permit area, one on the mine bench, and one adjacent to <br />a lower segment of the access road west of the waste disposal area. These stockpiles resulted from <br />soil material that sloughed from mine bench cut slope areas or accumulated from maintenance of <br />roadside ditches and culvert sumps. The soil in these two stockpiles was used during final <br />reclamation of the mine bench area in the summer of 2007. <br />Final reclamation has been conducted in the mine bench area, portal access road, and waste disposal <br />area. The portals have been sealed and backfilled. Coal material was placed and compacted against <br />the toe of the mine bench cut slope, and the area of compacted coal fill was subsequently covered <br />over by final reclamation grading operations in 2007. The bench area and upper road segment were <br />backfilled with onsite materials, compacted in lifts and graded to blend with surrounding <br />topography. Culverts along the portal access road (canyon segment) were removed and riprapped <br />channels were constructed to tie into natural drainage channels upstream and downstream of the <br />disturbed area. Final graded and topsoiled surfaces were roughened and seeded with a temporary <br />cover crop in June/July 2007, followed by hand broadcasting of the approved permanent seed mix <br />and straw mulch in November 2007. Small area exemption berms and silt fence sediment control <br />measures were installed at the reclaimed mine bench area and lower road topsoil stockpile site. <br />The coal waste disposal site was reclaimed contemporaneously with the portal bench and portal <br />access road in 2007. The lower road segment along the Munger valley floor will be retained for <br />the post -mining land use. During 2007, the road segment to be retained as permanent was <br />properly reduced in width, and sides of the road were ripped and seeded (with the exception of <br />the mile segment at the lower (west) end of the road, which is privately owned). Culvert <br />removal along the permanent road, width reduction along the private land road segment, and <br />reclamation associated with sediment pond removal at the coal waste disposal site was completed <br />in 2014. <br />The Loma Loadout received Phase I, II, and III Bond release in 2015 under SL2 and has been <br />removed from the permit boundary via TR26. <br />In 2009 the Division approved a Phase I bond release, S L 1, for backfilling, grading, and drainage <br />re-establishment on 17.2 acres which included 14.3 acres at the Munger Canyon site and 2.9 acres <br />at the Loma Loadout. With SL2, submitted September 3, 2014, CAM Mining, LLC requested bond <br />release for; Phase I on 1.30 acres at the Munger Canyon Mine, Phase II on 15.51 acres at the Munger <br />Canyon Mine, Phase II on 2.90 acres at the Loma Load out, and Phase III release on the Loma Loadout. <br />SL2 was approved on February 6, 2015. <br />7 <br />
