• Abandonment Plan <br />After all permit areas have been mined or at the time of filing a notice of abandonment (permanent <br />cessation), the following procedures will be employed. Appendix 13-11, Postmine Permanent Features, <br />summarizes the postmining process for the Seneca II Mine as the mine progresses through the bond <br />release process. <br />Last Alive Pit and Hiahwall. After all coal is removed, the area will be graded and the highwall reduced <br />(see F~ibit 13-2A, Postmining Topography and Permanent Features map). The site will be prepared <br />and soil replaced. <br />Internal Haul Roads. All haulage roads will have road base matedals dozed into cut areas where they will be <br />wvered by fill material during the road grading operations. The road area will be ripped approximately 18 <br />inches deep. The road site will then be graded, topsoiled, and seeded (see F~rhibits 131, Postmining <br />Vegetation Types, and Attachment 9-9, Topsoil Management Plan). <br />• Based on requests from postmine landowners, SCC proposes to leave several haul roads and one light-use <br />road as permanent postmine features. The locations of the proposed postmine roads are shown on 6diibit <br />132A, Postmining Topography and Permanent Features. In accordance with Rules 4.03.1(f)(ii) and 4.03.2 <br />(1)(g)(ii), permanent road requests have been mailed to the postmine landowners and will be inserted into <br />Appendix 13-11 a, Landowner Requests for Permanent Features, upon receipt by SCC. Senep Coal <br />Company, the postmine landowner for a portion of Roads E, E1 and C has requested that these roads be left <br />as permanent postmine features. SCC's request is presented in Appendix 1311a, Landowner Requests for <br />Permanent Features. <br />SCC has designed and constructed the postmine roads in accortlance with CDMG criteria. Typical <br />postmine permanent road cross$ections are presented in Exhibit 13.28, Permanent Road Cross- <br />Sections. The following actions will be completed to convert the haul and access roads from <br />operational roads to postmine roads: <br />1. The top road surface will be approximately 20 feet in width, as appropriate; <br />2. The road surtacing material from any narrowing of the section will be placed on the <br />remaining road width; and <br />• 3. All areas re-disturbed by road narrowing activi0es will be reseeded with Seed Mix #1 to the <br />edge of the road surface. <br />TR-37 73-37 Revised 04/05 <br />
