1991 ANNID~L RDCI~DIl44ZON REPORT Eatroduction In c~ipliance with Rule 2.04.13, Cyprus Orchard Valley Coal Company, Fermit No. C-81-038, sul~nits the following Annual Reclamation Report for the 1991 calerclar year. 1991 Reclamation Activities No additional acreage was newly disturbed by mining or construction activity during the 1991 calendar year. Reclamation activities conducted were primarily wnfiTled 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 material due to the topsoil and subsoil stripping operations required to aoce_cs gob for sale and shipment. Topsoil piles were seeded with temporary seed mix (Seed Mixture #6) and mulched. Subsoil piles were only seeded and were left in a rouc~ened condition to prevent erosion. One additional pile located at the parking lot area (see Exhibit 6) and oonsistir-g of windrowed subsoil material isolated for future reclamation purpcx~ was seeded with temporary seed mix i.rl response to NOV 91-004. Reclamation History An extensive reclamation project was initiated in the fall of 1977 to address the Orchard Valley upper mine area, middle mine area, mine roads, anti the new county road alignment near the existing coal stockpile. Zhe reader is referred to the following docwnents for a complete discussion of the details of this program: Zn 1979, a diversion channel and four sedimentation ponds were constructed to divert water away from the main mine facilities. Access roads to the sedimentation ponds and a parking lot were also constructed. 'Ihe revsletation program of 1979 addressed disturbed araac associated with these facilities and encompassed approximately 12 acres of reclamation. Reclamation activities in 1980 focused on revegetating lands disturbed through minor construction activities conducted in 1979. 'Ihe areas addressed in 1980 included the Orchard Valley Mine water pipeline, exploration drill pads, and miscellaneous 1-oadways. The majority of the acreage reclaimed in 1980, approximately 3.5 acres, was associated with reclamation of the water pipeline. The 1981 revegetation program en~assed minor disturbarx;es consisting of 1 Revegetation of cut and fill slopes was accot~lished in 1978 on previously seeded but sparsely vegetated and eroded slopes stemming from excessive water runoff caused by the lack of an effective water diversion system.
