OBSERVATIONS The following observations were made during an inspection of this 65 acre open 112 site. At the Operator's request, DMG conducted an inspection to check on both the current and proposed changes at the site and their impact on the current financial warranty. At this time, no new acreage has been disturbed since the last inspection conducted on June 18, 1996. The pit has been excavated another 10 feet in areas previously disturbed, but the mining plan has been adhered to, and grading and topsoil replacement will follow the already established guidelines. The City of Aurora is currently establishing plans both for the extension of 6th Avenue past the south side of the site, and the moving of a sewer line along the north side. Hart & Associates is working on an technical plans which will be added as an amendment to the permit, which would decrease the proposed lake area to be left on site and increase wetlands area by about 20 acres. The current plans appear to be consistent with the current level of disturbance. Once the amendment is submitted, the bond will need to be recalculated for the proposed reclamation plan changes. After City approval has been gained, DMG will wish to examine the changes to the site and evaluate whether any increase to the bond will be necessary. Some of the topsoil stored onsite has been used to reclaim 1-2 acres near the east side of the disturbance area. There has been no other change to the topsoil stockpiles at the site, and it should be noted that the former deficit still stands, although it does not effect the financial warranty at this time.
