following snow melt and following major storm events. Areas <br />• where erosion is observed will be evaluated to determine the <br />cause and whether maintenance is required. The evaluation will <br />include potential effects upon the post-mining land use, <br />revegetation success and water quality standards. If maintenance <br />is deemed necessary, appropriate corrective action will be taken <br />by the end of the fall planting season. If erosional features are <br />greater than 6" deep on the reclaimed slopes of the refuse pile, <br />corrective action will be taken within 30 days. This corrective <br />action may include minor reshaping, contour furrowing, installation <br />of erosion control matting, installation of straw dikes, dozer <br />tracking, and/or reseeding. Areas where erosion continues to be <br />a problem will be reviewed from an engineering standpoint and <br />redesigned if necessary. A rill and gully inspection report will be <br />prepared annually and submitted to the Division by June 1 of that <br />• year. The inspection reports will include a location map, a general <br />description of the erosion and a description of the corrective <br />measures to be used. <br />(f) The coal refuse material to be disposed of during mining operations is <br />not considered combustible, physically unstable, or acid - or toxic - <br />forming. Chemical and physical analysis for this material is contained in <br />Appendix 6-2. Refuse separated from the raw coal mined will be placed <br />in the refuse disposal areas described in Section 2.05.3(8). The refuse <br />piles will be constructed to the final contours shown in Exhibits 6C and <br />9C, in this Tab Section and Exhibits 51 and 52, Tab Section 13. <br />Non-coal wastes inGuding flammable liquids, paints, garbage, and <br />lumber are collected by a refuse removal service and disposed of in a <br />14-28 (Retype 12/16/96) <br />
