This equates to <br /> approximately 51 acres. Pre-existing road culverts were removed, <br /> and the roads were graded to fill the inside ditch and achieve a <br /> positive gradient to the outside. The roads were ripped to an <br /> eighteen inch depth, then fertilized, seeded and mulched. <br /> Approximate cost was $92 ,000. Contractor: Dirt-N-Iron, Loma, <br /> Colorado. <br /> Rock Tunnel Project: Concrete foundations were demolished and <br /> buried against the highwall remnant. A forty eight inch pipe was <br /> installed in each entry. The pipes were buried under the highwall <br /> backfill , and are anchored at their terminus by a concrete wall. <br /> The entry is secured by a locking steel grate. The entire area was <br /> ripped, a portion was topsoiled and approximately seven acres <br /> fertilized, seeded and mulched. Approximate cost was $75,000. <br /> Contractor: ERM Enviroclean, Denver, Colorado. <br /> Waste Rock Dump: The Rock Tunnel Dump was graded to achieve the <br /> desired contour. Topsoil was excavated from the outside of a <br /> nearby road and applied at a minimum thickness of twelve inches. <br /> Drainage swales were established on the north and south sides of <br /> the approximately eleven acre dump. The dump and borrow areas were <br /> fertilized, seeded and mulched. Approximate cost was $85,000 . <br /> Contractor: Wagner Construction, Craig, Colorado. <br /> Mines 1 and 2: Concrete foundations and buildings were <br /> demolished and removed to the highwall remnants. Seven underground <br /> entries were backfilled, as were the highwall remnants at both mine <br /> areas. Fan entries and associated roads were reclaimed. Steep <br /> slopes and sharp road cuts in the vicinity of the mine entries and <br />
