It mainly covers bank shaping and mist grading, <br />topsoil replacement, and revegetation activities. Abridge vas built across the Uncompahgre River to access the <br />site from the operator's main processing facility. The bridge is inside [he permit boundary, but will remain after <br />reclamation. <br />Current disturbances are fairly well represented in the annual reports, and an assessment was made during the <br />8/8/00 inspection. <br />At this time the bond amount appears to be adequate, based on the estimate of costs which were calculated on <br />3/29/01. Current figures are based as follows: it is known that only a portion of Phase 1 is disturbed, by stripping, <br />mining, and topsoil stockpiling; some of the banks are shaped to their final gradient, some are slightly steep, some <br />are vertical; slopes below water line are considered adequate; all topsoil is stockpiled along the western pond <br />margin, and will be hauled by scraper and smoothed by dozer; along with standard revegeta[ion costs, some weed <br />control is considered needed, specifically the bindweed covering the stripped areas and a small patch of thistle. <br />Tliis bond estimate is based on current disturbance only, and should be reassessed in a few years after the operation <br />grows. Current reclamation costs are $15,003. <br />Bob Oswald, DMG. <br />
