(Page 21 MINE ID # OR PROSPECTING ID Jl M-1984-001 INSPECTION DATE 4/14/00 S INITIALS WHE OBSERVATIONS This inspection occurred in response to operator request to clarify remainin reclamation tasks necessary to achieve full release of warranties and termination of permi . John Schmahl accompanied the DMG inspector throughout the inspection. Ron Tipping and E Settle, from Grand Junction Pipe & Supply Company, were present during the inspection. The urface Rock Pit is approved for 28 acres total affected area. The phased reclamation pan indicates that approximately 13.5 acres may be affected at any given time. The permit area is divided into two locations, areas A and B. Area A is a quarry type extraction of metamorphi and igneous rock, approved for 18 acres affected area, approximately 9.5 acres may be affecte at any given time. Area B is a granite boulder and backfill material harvesting area, approved fo 10 acres affected area, approximately 4 acres may be affected at any given time. Permit stat s is active. DMG holds 527,000 financial warranty. During the inspection, the operator submitte updated maps and aerial photos of the permit area. Area A - Mine identification sign was posted. Public access is controlled b locked gate. The boundary of affected lands was sufficiently delineated to verify that mini g activities have remained within approved areas. Highwall was visually estimated at 40'-60' tall. Near vertical sections of the highwall were interrupted by several benches. The highwall app ared to have been excavated from competent massive rock, evidence of instability appeared lime ed to potential for rock fall. Stockpile of 3" minus material, located at the Phase II area and containing approximately 60,000 cy, appeared well vegetated and stable. Vegetative cover for the stoc pile, including the steep outslope, was well established and included Pinion and Juniper trees, ucca, Four-wing saltbush, Rubber rabbitbrush, Sage brush, Western wheatgrass, Crested w eatgrass, Smooth brome, additional unidentified grasses, Yellow sweet clover, Broom snakewe d, Flexweed, and Russian thistle. Presence of noxious weeds was not observed. Upland dra Wage is conveyed around the stockpile by an upland diversion ditch with culvert outlet. Evidence f mild erosion was observed at the outfall point for the upland diversion culvert. DMG recommend that the operator place large rock at the culvert outfall to dissipate the energy of water discharge g from the culvert and control erosion. Affected area drainage was appropriately controlled with b rms and sediment basins. Reclamation Plan for area A indicates that the highwall will be stabilized with enches. Benches are to be 10'-15' wide and spaced at 20' elevation intervals. Vegetative cov r for the benches is not required. The approved reclamation plan stipulates that the 60,000 cy st ckpile of 3" minus material must either be removed from site, or relocated to the base of the high all and utilized as backfill to attain the approximate 15% final slope requirement. The 15% final slope requirement extends from the base of the highwall to the 25' buffer zone bordering Hwy 41 of the Phase I area. Topsoil or fines, approved as suitable growth medium, are to be distrib ted over affected areas and contoured with 2" creases to reduce runoff and control erosion. he surface of the affected lands are to be stabilized with an appropriate vegetative cove , which includes transplanting 60-70 pine trees. Affected lands will be reclaimed to support ildlife habitat post mining land use. DMG cannot approve full release of warranties and terminate he permit until the conditions of the approved reclamation plan are satisfied in accordance with he Act and Rules. Copy of the approved reclamation plan for Area A is attached for reference.
