In response to Stipulation 22, cross section B-B' shown on Map 13, Post-Mining • <br />Topography and Cross Sections, presents the topography of the portal azea. Basin <br />Resources received approval from the Division to use the excavated portal area as a <br />concrete disposal site. During the demolition phase of final reclamation, concrete slabs <br />and footers were broken up and placed in the approved disposal site. The remaining <br />depression was filled by cutting the areas shown on the cross section. <br />(d) Topsoil Removal. Storage. and Redistribution <br />Approximately 12,000 cubic yards of topsoil was removed and stockpiled after <br />regulations were promulgated requiring the recovery and storage of topsoil for use in <br />final reclamation. Topsoil piles were constructed in an oval shape with a containment <br />ditch azound each pile and seeded with the approved rangeland seed mix. Signs <br />identifying the topsoil piles were posted on each pile. <br />Soil material was not salvaged prior to the construction of the majority of the mine <br />facilities area because most of the Golden Eagle construction was prelaw. Topsoil <br />recovery was limited to post-law facilities including the Refuse Disposal Area <br />and Pond 5. As such, in 1985 a plan was established and approved, whereby salvaged <br />soil was to be spread on areas which will be most limiting to revegtation efforts. Iv[ap 12, <br />Surface Disturbance and Post Mining Land Use, was prepared to assess this situation. <br />The map defined areas of Limited Disturbance, Disturbed Areas with No Refuse, and <br />Disturbed Areas with Refuse Exposed. <br />Table 20 demonstrated the areas to be reclaimed with the salvaged topsoil. In addition a <br />topsoil borrow area was permitted to achieve the reclamation for the coal processing <br />waste bank requirement of four feet of nontoxic material, including a minimum of one <br />foot of suitable topsoil material. <br />(e). Revegetation <br />Seeding and mulching of the areas occurred immediately after final grade w•as <br />established, topsoil redistributed if available, and compacted areas ripped to a depth of 18 <br />inches. The majority of the disturbed areas were seeded and mulched in the fall of 1996. <br />The topsoil borrow area and Refuse Disposal Area were seeded in the spring of 1997, <br />Sediment pond areas 003 and 004 were seeded late in 1998. <br />Preparation of the seed bed consisted of either discing the seed bed or when on steeper <br />slopes, ripping the seed bed on contour to a depth of 8-12 inches. Mulch was placed <br />using a mulching machine that broadcast seeded at the same time. Seed rates were <br />doubled. <br />~ 22.05-16 (PetmitRenewal~e+yseen-3/~l/00) <br />~ N'o3 • <br />
