DRMS WORST CASE RECLAMATION BOND EXHIBIT L <br />1. Introduction <br />As shown on Map F-1, Reclamation Plan, the site will be restored to high altitude rangeland, and <br />some commercial area around some of the buildings that will remain. The worst case reclamation <br />scenario at the Revenue Mine will take place early in the mine life, when the entire Revenue waste <br />pile is opened up and the 4.53 acres of Atlas pile has also been opened. It is shown on Map L-1. <br />Also, the additional disturbance in the lower storage area of 0.37 acres will be utilized. It is <br />expected that the worst case reclamation scenario will occur when the areas described above are <br />opened, but no topsoil has yet been imported for the reclamation. It is assumed that the <br />underground development for the mill and additional underground storage will be completed at this <br />point. It is at this time in the mine's life that the greatest amount of earthwork needs to be <br />conducted for successful reclamation. <br />2. Worst Case Reclamation Details <br />The bond estimate is based on the following details. Table L-1 shows the bond estimate. <br />Grading all of the disturbed areas steeper than 3H:1 V to 3H:1 V. The retaining wall near the <br />dry building will be bulldozed and backfilled as part of the reclamation process. All wood <br />and steel will be removed from the site. <br />The thickener and its concrete containment will be removed for reclamation. The "TH" <br />drawings included in Appendix 17 show the details of the thickener, its supports and its <br />concrete foundation. <br />Topsoil required is based on the areas and replacement thicknesses shown on Map L-1. The <br />operator will document the importation of topsoil in the Annual Reports to the Division. <br />All topsoil areas will need to be seeded and mulched. <br />The underground storage portals and mill portal will have to be backfilled with an MSHA <br />seal, and a bat gate will be installed on the Revenue tunnel portal. <br />o See Table E-1 in Exhibit E for a detailed description of portal closure. <br />Revenue Mine June 2015 L-1
