EXHIBIT E RECLAMATION PLAN <br /> The reclamation plan will create lakes with rangeland above the waterline, which is the primary <br /> post mining land use. The lake will have slopes of 3H:1 V or less. Exhibit F maps shows the final <br /> configuration of the site. Disturbance area is limited to 50 acres. The reclamation bond is based <br /> on this area. Exhibit L contains the proposed bond calculation. <br /> 1. Site Grading and Topsoil Replacement <br /> Final slopes will be a maximum of 31-1:1 V throughout the site, except slopes that are ten feet <br /> below the waterline within lakes, which will be a maximum of 2H:IV. Topsoil will be replaced <br /> to a depth of 8 to 12 inches. The topsoil will be placed on finished slopes as they are made, <br /> eliminating the need for most stockpiling. An excess of topsoil is present on the site, so no <br /> topsoil will need to be imported. Most of the topsoil is not stockpiled, but simply moved during <br /> the mining process as part of contemporaneous reclamation. Topsoil stockpiling procedure is <br /> covered in Exhibit D. <br /> Backfilling of overburden will take place to accomplish the final graded slopes as delineated in <br /> this plan. This will include compaction for stability. All grading shall be done in a manner to <br /> control erosion. All highwalls will be stabilized to final slopes prior to topsoil replacement. <br /> 2. Protection of the Prevailing Hydrologic Balance <br /> Reclamation of the site will also include the installation of inflow/outflow structures along the <br /> berm between the final groundwater lake and the Yampa River. These structures are detailed on <br /> Map F-IB. The structures will be built once mining and reclamation has completed within 250' <br /> of the Yampa River. <br /> The purpose of these structures is to prevent lake capture following reclamation. The majority of <br /> the Bunn Ranch Pit is within the 100-YR floodplain (FEMA Zone A3) for the Yampa River. The <br /> primary risk to the prevailing hydrologic balance in this area is the potential for lake capture <br /> following reclamation; such a capture could dramatically change the course of the river, affecting <br /> downstream landowners as well as water users on the Yampa River. Therefore, structures will be <br /> installed to facilitate the stability of the berm between the lake and the river and stable conditions <br /> even during flooding. <br /> Bunn Ranch Pit <br /> February 2021 E-1 c i xw�at nss�niaces MAX <br />
