• iii ~~iiiiiiiiiu iii MEMO TO FILE PERMIT M-1996-008 NORTH R-3A PIT WESTERN GRAVEL, INC. 3/2912001 RECE~~ED APR o~z 2oot Oirision of Minera~s.,.,a ue,,, tea: • 5 19,/ r. i ~;',.`.: M~1-1996 - 008 .~ w.~.. ~~~~ , The bond amount for this permit is $16,393, and is the amount that was calculated in 1996 for reclaiming disturbances at the end of all mining, Phases 1 and 2 combined. It mainly covers bank shaping and mist grading, topsoil replacement, and revegetation activities. Abridge vas built across the Uncompahgre River to access the site from the operator's main processing facility. The bridge is inside [he permit boundary, but will remain after reclamation. Current disturbances are fairly well represented in the annual reports, and an assessment was made during the 8/8/00 inspection. At this time the bond amount appears to be adequate, based on the estimate of costs which were calculated on 3/29/01. Current figures are based as follows: it is known that only a portion of Phase 1 is disturbed, by stripping, mining, and topsoil stockpiling; some of the banks are shaped to their final gradient, some are slightly steep, some are vertical; slopes below water line are considered adequate; all topsoil is stockpiled along the western pond margin, and will be hauled by scraper and smoothed by dozer; along with standard revegeta[ion costs, some weed control is considered needed, specifically the bindweed covering the stripped areas and a small patch of thistle. Tliis bond estimate is based on current disturbance only, and should be reassessed in a few years after the operation grows. Current reclamation costs are $15,003. Bob Oswald, DMG.
