miscellaneous roadways, Steven's Gulch wellfield structures, and the scale house <br />and truck scales near the truck dtm¢~ station. <br />Construction of the west ridge waste disposal area was initiated in July, 1983. <br />Lands available for reclamation at this site have been seeded and mulched on an <br />approximately annual basis since development began. Zhe west ridge waste <br />disposal site encompasses approximately 3.37 acres. Approximately 2.20 acres of <br />this site are currently reclaimed. Reclamation of the old waste disposal site <br />near porxls 1 and 2 was completed in November of 1983. Vegetation was established <br />on this 0.86 acre site the following spring. Development of the east ridge waste <br />disposal site was initiated in 1983 in conjunction with development of the west <br />ridge site. 'The east ridge has seen topsoil salvaged and an intermediate <br />material stockpile established to ac~mnodate material being generated from the <br />west ridge development. <br />Reclamation of the Orcharri Valley West Mine fill slopes and associated <br />disturbance was completed by the fall of 1987. Slope instability necessitated <br />the relocation of topsoil at the mine site and subsequent reseeding arri mulching <br />of both the new pile and the old pile footprint was completed in the fall of <br />1990. <br />Several small topsoil piles exist throughout the various distuxha~x~.e areas on the <br />mine. 'Those piles projected to remain undisturbed for longer than five years are <br />seeded with the permanent seed mixture. Those piles projected to be <br />redistributed within five years are seeded with the temporary seed mixture. <br />Several seed mixtures have been utilized at the Orchard Valley mine. The <br />following tables ~~rize the various seed mixes used historically and currently <br />to stabilize disturbed areas. <br />Table 1.
