Soils were identified as <br />Delson Inam, 3 to 12 perverrt slopes. Six feet of topsoil was salvaged <br />fran the 0.35 acre site and stockpiled along the eastern perimeter of the <br />site. Upon cessation of operations, the storage tank will remain for use <br />by the Pitkin Mesa Pipeline Company. ire topsoil is available for the <br />reclamation of other mine areas. <br />During the initial construction of the old waste disposal area during the <br />SulmOer' of 1980, six inches of topsoil was removed with a dozer and stock- <br />piled nearby. The stockpile was re•.~eeded in the Fall, according to Section <br />2.05.4(2)(e). The old wastepile was expanded to the south during <br />October, 1982. Eight irx3res of topsoil was salvaged and stockpiled. The <br />old waste pile was filled to capacity in August, 1983, and final soil <br />Dover and grading was congrleted. Following redistribution of six inches <br />of topsoil with a front end loader and blade, the surface was ripped. Due <br />to the limited quantities of topsoil available at the site, only the top <br />of the waste a;_~i area owld be topsoiled. Per the Division's <br />reocamnendation, fertilizer was applied to the cnrtslopes. The area was <br />fertilized and seeded during November, 1983. Vegetation was successfully <br />established by the next year. <br />7.n the Spring of 1985, spontaneous oranbastion in the old waste rock fill <br />was detected. Surficial cracks were tamped closed to cut off contact with <br />oxygen. As this method proved unsuccessful, topsoil and subsoil were <br />excavated and stockpiled. The hot material was excavated, cooled and <br />transported to the West Ridge disposal site. Excavated materials were <br />also utilized by the western Slope Carton wash plant facility. The area <br />will be reoontoured, subsoil and topsoil redistributed aryl the area seeded <br />during the Sunanes of 1988. <br />ire truck scales near the truck dump station were wnstructed during ta5e <br />Summer, 1981.
