In 1979, a diversion channel and four sedimentation ponds were constructed to divert water <br />away from the main mine facilities. Access roads to [he sedimentation ponds and parking lot <br />were also constructed. The revegetation program of 1979 addressed disturbed areas associated <br />with these facilities and encompassed approximately 12 acres of reclamation. <br />The 1981 revegetation program encompassed minor disturbances consisting of miscellaneous <br />roadways, Steven Gulch well field structures, and the scale house and truck scales near the truck <br />dump station. <br />Construction of the West Ridge Waste Disposal Area was initiate in July, 1983. Lands available <br />for reclamation at the site have been seeded and mulched on approximate annual basis since <br />development began. The west ridge disposal site encompasses approximately 3.37 acres. <br />Approximately 2.02 acres of this site are currently reclaimed. Reclamation of the old waste <br />disposal site near ponds 1 and Z was completed in November of 1983. Vegetation was <br />established on this 0.86 acre site the following spring. Development of the West Ridge Disposal <br />site was initiated in 1983 in conjunction with development of the west material stockpile which <br />was established to accommodate material generated by the West Ridge Disposal area <br />development. <br />Reclamation of the Orchard Valley West Mine fill slopes and associated disturbances was <br />completed by the fall of 1987. Slope instability necessitated the relocation of topsoil at the mine <br />site and subsequent reseeding and mulching of both the new pile and the old pile footprint. This <br />was completed in the fall of 1990. <br />Several small topsoil piles exist throughout the various disturbance areas of the mine site. Those <br />topsoil piles projected to remain undisturbed for longer than five years are seeded with the <br />permanent seed mixture. Those piles projected to be redistributed within five years are seeded <br />with the temporary seed mixture. <br />Page -3- <br />
