1993 Reclamation Activities: No additional acreage was newly disturbed by mining or construction activity during the 1993 calendar year. Reclamation activities conducted included seeding and mulching operations on the outslopes of the west ridge waste pile. (See location 32 on exhibit 7). Topsoil and subsoil piles in the vicinity of the West Ridge waste pile which were disturbed as a result of pile reconstruction activities were seeded with'the temporary seed mix (seed mixture #6 (during the fall of 1993. At the close of 1993 reclamation activities on the West Ridge waste pile, the total reclaimed acreage on this site was approximately 2.85 acres. Of this total acreage, 0.83 acres was newly revegetated in.1993. Approximately 0. 12 acres of additional disturbance occurred in association with a landslide at the west mine portal cut during 1993. Topsoil was salvaged from an area surrounding the slide crest and stockpiled near this location (refer to Exhibit 8 in this report and Map No. 8 -6, Permit No. C -81- 038). Disturbed areas associated with this slide and the subsequent stabilization work were seeded with the temporary seed mix (seed mixture #6) mulched. Table 7 of this report depicts reclaimed acreages throughout the mine site has been revised to reflect 1993 activities. 1992 Reclamation Activities: No additional acreage was newly disturbed by mining or construction activity during the 1992 calendar year. Reclamation activities conducted included seeding and mulching operations on the outslopes of the west ridge waste pile. (See location 32 on exhibit 7). Topsoil and subsoil piles in the vicinity of the West Ridge waste pile which were disturbed as a result of pile reconstruction activities were seeded with the temporary seed mix (seed mixture #6 (during the fall of 1992. At the closed of 1992 reclamation activities on the West Ridge pile, the total reclaimed acreage on this site was approximately 2.02 acres. A total of 0.63 acres was newly revegetated in 1992 with the remainder having been seeded in 1983. At the close of 1983 reclamation activities on the West Ridge waste pile, the total reclaimed acreage on this site was approximately 2.20 acres. During gob salvage and sale operations occurring in the first and second quarters of 1992, approximately 0.81 acres of seeded topsoil and subsoil was stripped from the pile to allow access to the gob. Table 7 of this report depicting reclaimed acreages throughout the mine site has been revised to reflect this sequence of events. 1991 Reclamation Activities: No additional acreage was newly disturbed by mining or construction activity during the 1991 calendar year. Reclamation activities conducted were primarily confined to interim stabilization seeding and mulching operations on topsoil piles and subsoil piles in the vicinity of the West Ridge waste pile (See exhibit 7). Soil storage piles in this area saw additions of materials due to the topsoil and subsoil stripping operations required to access gob for sale and shipment. Topsoil piles were seeded with temporary seed mix (see mixture #6) and mulched. Subsoil piles were only seeded and were left in a roughened condition to prevent erosion. One additional pile located at the parking lot area (See Exhibit 6) and consisting of windrowed subsoil material isolated for future reclamation purposes was seeded with temporary seed mix in response to NOV 91 -004.
