at the Rock Tunnel. Revegetation requirements and a seed mixture <br /> is contained within the permit, which was used but slightly <br /> modified based upon comments from Division revegetation specialists <br /> and Resources' consultants. A brief discussion of each of the four <br /> projects, including rationale for field changes made during <br /> performance of each project, follows. <br /> TABLE 1. 1996 RECLAIMED ACREAGE AND PROJECT COSTS <br /> PROJECT ACREAGE RECLAIMED PROJECT COST <br /> ROCK TUNNEL 7.0 $71,236 <br /> ROCK TUNNEL WASTE 14.5 $88,710.75 <br /> DUMP <br /> MINES 1 AND 2 18.5 $155,211.50 <br /> ROADS E, F, G 51 .0 $89,995.50 <br /> TOTAL 91.0 $405,153.75 <br /> Rock Tunnel Waste Dump <br /> The objectives of the Rock Dump project was to establish final <br /> contours at the top of the facility, apply topsoil or topsoil <br /> substitute to an average depth of fourteen inches, establish <br /> hydrologic controls at the margins of the dump, and revegetate the <br /> facility and borrow areas. <br /> When constructing the dump, Resources salvaged an estimated 3,400 <br /> cubic yards of topsoil. The permit requires an average soil depth <br /> of fourteen inches over the entire twelve acre facility. <br /> Therefore, a deficit of about 19,200 cubic yards of topsoil existed <br /> at the site. The permit does not state how or where the deficit <br /> would be overcome. A source area for the deficit material was <br /> identified as the outslope of Road B between the intersection of <br /> Roads B, C, D east to the Rock Tunnel vicinity. Utilization of <br /> this material, which was located within one half mile of the dump, <br /> would accomplish the goals of providing topsoil substitute, and of <br /> reducing the road width, a road reclamation goal. The bid required <br /> specific reclamation tasks be performed at the borrow area as well <br /> as at the dump. <br /> Wagner Construction of Craig was the low bidder, at $88,900. Final <br /> payment is estimated at $88,710.75. Work was initiated on July 23 , <br /> 1996. Material was removed from the borrow area with a trackhoe, <br /> and loaded into trucks with the hoe or by a wheel loader. Five <br /> trucks were used to haul the material to the dump, where it was <br /> spread by a D-6D dozer. This dozer also performed final <br /> contouring, diversion construction and benching. <br /> 11 <br />
