- :._, <br />Mr. Randall P. Price <br />April 15, 1994 <br />Page Two <br />In chose areas where remaining fill is indicated, there were also a number of shallow to <br />moderately deep (5-15 feet) sub-parallel erosional gullies. During construction of the overburden <br />stockpile, these gullies were filled in with overburden material. During final backfilling and <br />grading activities, Kerr established a relatively uniform regraded surface and did not attempt to <br />reestablish the previous gullies which would tend to channelize runoff and result in potential <br />erosional instability. Overburden material remaining in these gully areas is probably also a <br />component of the indicated remaining fill. <br />During final backfilling and grading activities, Kerr utilized both conventional survey methods <br />and visual indicators (variations in material color and the presence of vege[ative material <br />including roots) to determine the lower limit of the stockpiled material. Every effort was made <br />to recover all stockpiled material for placement in the adjacent 720 Pit. <br />Given the mapping information indicating possible remaining fill in two locations on the south <br />end of the former overburden stockpile area, Kerr proposes to inspect these areas for visual <br />indications of any remaining fill. It is anticipated that the volume of any remaining fill will not <br />be significant and [hat this material can be effectively placed and blended into the existing fill <br />during topsoiling activities. Based on DMG comments during our informal site inspection in <br />March, Kerr also plans to shift the postmining drainage at the south end of the 720 Pit <br />downslope to enhance long-term stability. This minor modification will require less than one <br />day of dozer time and will also be completed in conjunction with topsoil replacement activities <br />in June. <br />We appreciate your continuing cooperation and input relative to effective final reclamation of <br />the Marr Mine. Please feel free to contact me if you have any questions regarding this <br />transmittal or require additional information relative to our partial bond release request. <br />Best regards, <br />TerraMatrix for Kerr Coal Company <br />Jerry Iettleton <br />Project Manager/Senior Engineer <br />JMN:cmc <br />enclosures <br />cc: D.
