Menzer Quarry Annual Report Additional Sheets Permit M-76-009-HR Anniversary Date: December 31, 1997 Centennial Materials Annual Summary: Clearly the most significant event of the last year was the approval of the large amendment which added about 116 acres to the previous permit. This amendment not only added land to the permit, but totally revised the mining and reclamation plans. This plan was done in coordination not only with the state requirements, but also with the local requirements and the concerns of local people over visual impatt. Other than this amendment approval, the mining operation itself actually proceeded as though it was still operating under the previous permit. Mining approaches gradually changed as Dart of the process of shifring to the new approaches included in the permit amendment. By the end of the year, sequencing and actual mining procedures were occurring in accordance with the new plan:;. Now that the change over to the new approaches has been almost completed, Honing in the future will follow the new plans rather than the old approaches. The following information is keyed to the enclosed annual report map. Map: Disturbance and affected land azea changed little over the past year. Each section de::cribes the changes. Revegetation (5.3 acres) -This revegetation represents what was done over the past several years to revegetate disturbed areas on the site. No revegetation was done in 1997. This is actually a reduction of about 0.5 acre from the 1996 report. This reduction is due to a slight enlazgertent of the mining northwazd as part of initiating the new plans. It needs to be noted, that over the next several years, all previous reclamation will be destroyed as the new plans are implemented. But by the time that is destroyed, additional reclamation of equal or greater amount will replace it, but in other locations. Plant fr Processing (15.8 acres) -Although this appears to be a slight reduction in acreage, actually that is an artifact of various alterations in other categories of land combined with ::ome redefinition of lands as a result of the amendment. In fact, the land involved in the plant azd processing facilities changed very little during the last year. Mining (14.7 acres) -This, as shown on the map, is divided into two pans. Most of the mining occurred in the smaller azea on the south side of the quazry, but mining elsewhere within the large zone, primazily lower in the pit and west of the processing plant, also occurred. The large mining area expanded northward somewhat and cut into the older revegetation in that area. A fault wa; encountered in this area. To adjust for this feature, removal of the top of the hill forming Stage 1 of Phase 1 (see 1997 amendment) is being accelerated slightly so a road can be built on more s':able land. This fault does not appeaz to present any major problems as its exposure will be totally removed during Stage 1 of Phase 1. Menzer Quarry 1997 Annual Report (M-76-009-HRI Due: Dec 31, 1997 Page 1 of 2
