<br />minor construction activities conducted in 1979. Zhe areas addressed in 198C <br />itx:lude3 the Orchard Valley Mine water pipeline, exploration drill pads, and <br />miscellaneous roadways. The majority of the acreage reclaimed in 1980, <br />approximately 3.5 acres, was associated with reclamation of the water pipeline. <br />4he 1981 revegetation program P~+TM+.rs~ minor disturbances consisting of <br />miscellaneous roadways, Steven's Gulch wellfield structures, and the scale house <br />aryl truck scales near the truck dump station. <br />Construction of the west ridge waste disposal area was initiated in July, 1983. <br />Lards available for reclamation at this site have been seeded aryl mulched on an <br />approximately annual basis since development began. The west ridge waste <br />disposal site PTM~* ~s~ approximately 3.37 acres. Approximately 2.02 acres of <br />this site are currently reclaimed. Reclamation of the old waste disposal site <br />near ponds 1 and 2 was owiq~leted 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 accor[miodate material being generated from the <br />west ridge development. <br />Reclamation of the Orchard 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 and mulching <br />of both the new pile and the old pile footprint was o~leted in the fall of <br />1990. <br />Several small topsoil piles exist throughout the various disturbance areas on the <br />mine. those piles projected to remain undisturbed for longer than five years are <br />seeded with the permanent seed mixture. ?hose 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. Zhe <br />following tables summarize the various seed mixes used historically aryl currently <br />to stabilize disturbed areas. <br />Table 1.
