10 Remove available topsoil from the Phase 3 mining area and backfill on <br />regraded slopes of Phase 2 above the lake surface. <br />11 Remove overburden and place below water level in the Phase 1 lake. 1.0 <br />12 Mine Phase 3 (Approximately 15.1 acres). Use reject fines from process- <br />ing to fill Trench #1. Use reject fines to backfill the slopes of the final <br />Phase to 3.OH:1.OV. 30.0 <br />9 Fill Trench #2 0.5 <br />10 Reseed and mulch lake slope area and upper dryland areas 0.25 <br /> Total 81.75 <br />5. ROAD ACCESS <br />Primary access to the property is US Highway 50 which provides excellent access to Interstate 70 <br />interchange at Fruita. The haul route from the pit intersects US Highway 50 at an existing <br />channelized intersection at the point that the N-S section line between Sections 11 and 12 meets the <br />Highway. This is the graveled portion of 15 Road proceeding south to the permit area. Map C-1 <br />indicates the location of the haul route from Highway 50 to the permit area. This route follows ex- <br />fisting roads established as part of the previous refinery activities. Improvements are lirt~ited to <br />maintenance of [he gravel surfaces. Given the maximum production of the site coupled with avail- <br />able tmcks, it is estimated that a peak of 15 trips per hour will utilize the haul route at maximum <br />production. Two types of trucks will be used; tandem axle trucks with a capacity of 14 tons and 24 <br />ton capacity belly dump trucks. It is expected that 90% of the trucks moving the products off site <br />will be of the belly dump type. In order to control dust, water will be used on an as needed basis. <br />Magnesium chloride may also be considered if needed. <br />6. MINE FACILITIES <br />The site will consist of a portable crushing and screening plant, portable stacker conveyors, portable <br />asphalt plant, portable truck scale, portable dewatering equipment, portable scale house trailer and <br />Gilsanite Pit 5/03 16 <br />
