In order to continually monitor the ma- terial being placed in the waste rock refuse pile, roof, floor, interburden, and coal samples will be taken in loca- tions as depicted on Map 2-S and where inordinate concentrations of waste rock are encountered (roof falls, rockwork, etc.) to supplement the planned sample locations. • The projected locations for waste rock analysis were chosen on the basis of: future main and submain entry develop- ment; periphery of Lease C-32710; and areas in which, due to the depositional stratigraphy, a fades change in waste rock may be present. These sample lo- cations exceed the Division's recom- mended I mile spacing, The results of waste rock and coal analyses will be reported annually in conjunction with the Annual Subsidence and Hydrology Report. If the potential for damage to the hydrologic regime is apparent from sample analyses (increas- ing pyritic sulfur, decreasing pH, etc.), a mitigation plan will be devel- oped and implemented after consultation with the Division.
