1992 AHNIII-L RDCLAt~aTICiQ REPORT Introduction In ~liance with Rule 2.04.13, Cyprus Orchard Valley Coal Company, Permit No. C-81-038, submits the following Annual Reclamation Report for the 1993 calendar year. 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 reoonstxvction 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 aryl the subsequent stabilization work were seeried with the teng~orary seed mix (Seed Mixture #6) arcs mulched. Table 7 of this report depicts reclaimed acreages throughout the mine site has been revised to reflect 1993 activities. Reclamation History An extensive reclamation project was initiated in the fall of 1977 to address the Orcharxl Valley upper mine area, middle mine area, mine roads, aryl the new county road alignment near the existing coal stockpile. The reader is referred to the following docwnents for a cw~lete discussion of the details of this program: In 1979, a diversion channel and four sedimentation ponds were constructed to divert water away frown the main mine facilities. Access roads to the sedimentation ponds and a parking lot were also constructed. The revegetation program of 1979 addw~ccr3 disturbed areas associated with these facilities arcs encompassed approximately 12 acres of reclamation. Reclamation activities in 1980 focused on revegetating lands disturbed thrcxx~r Revegetation of cut and fill slopes was accomplished in 1978 on previously seeded but sparsely vegetated and eroded slopes stemming fran excessive water runoff caused by the lack of an effective water diversion system.
