I1 <br />than undisturbed areas, although not of the magnitude of the analysis. [The Division finds that all <br />factors less cover of the Universal Soil Loss Equation (USLE) equation used are similar. The more <br />protective "C" or cover factor of the reclaimed areas results in the finding.] <br />Remaining Reclamation Work <br />The Division determined the remaining reclamation work required at the site, and developed a cost <br />estimate to accomplish this work by a third party contractor. The estimated cost to complete the <br />remaining required reclamation was, as of July 13, 1998, $2,334,441, and includes, as a separate line <br />item, monies (financial assurance) for water quality monitoring for ten years. <br />Water Quality <br />By review of the Annual Hydrologic Reports submitted by CEC, the Division determined that no <br />surface or underground water pollution had occurred or was occurring. There had been no discharge <br />of surface water from the site (sedimentation ponds) at the site. Samples from monitoring wells <br />indicated no impact to the quality of ground water about the site. In addition, from geological, <br />geotechnical, topographic, climate and operational information found within the Permit, the Division <br />determined that the probability of future occurrence of pollution is low (requiring, at this time, no <br />estimated cost for abatement). <br />IV. CONCLUSIONS <br />Phase I <br />Based upon a review of the mine Permit, the Bond Release Application, and previous and recent site <br />inspections, the Division finds that CEC has backfilled, graded and established drainage on 179 acres <br />of 413 disturbed at the Keenesburg Mine in accordance with the approved reclamation plan. Areas fo <br />which Phase I Bond Release has been applied meet the criteria of Rule 3.03.1(2)(a). <br />Phase II <br />The Division finds that topsoil was replaced over the 111 acres of the Application in accordance with <br />the approved reclamation plan. <br />The Division finds that the 1985 reclaimed parcel fails to meet the cover standard when the vegetation <br />data collected during August 1996 is used as a basis for evaluation. However, investigation of <br />previous vegetation monitoring data collected in 1994 and 1995 finds that the 1985 reclaimed parcel <br />met the cover standard in both 1994 and 1995. The 1994 and 1995 vegetation sampling data was not <br />submitted in the Application but is available in the 1994 and 1995 Annual Reclamation Reports. The <br />1985 parcel meets the requirements of Rule 3.03.1(2)(b). <br />11 August 93 <br />
