6.0 EXHIBIT E—RECLAMATION PLAN <br /> 6.1 Post-Mining Land Use <br /> Approximately 2/3 of the Morton-Holton Lakes Sand and Gravel Pit is located in the 100- <br /> year floodplain of the South Platte River. Weld County Department of Planning Services <br /> considers land located in the 100-year floodplain to be suitable for agriculture, recreation, and <br /> wildlife uses. The principal post-mining land uses proposed in this Reclamation Plan include <br /> developed water storage and wildlife habitat. These uses are compatible with the surrounding <br /> land uses and with the Weld County planning goals. <br /> In order to minimize surface disturbance at the Morton-Holton Lakes Pit, mining and <br /> reclamation will be conducted concurrently to the greatest extent practicable. The operator will <br /> concurrently reclaim pit wall areas in locations where mining has been completed. Reclamation, <br /> including re-grading and seeding will be completed in 2 to 3 years following the completion of <br /> mining operations in Stages 3-7. Stages 1 and 2 will be reclaimed over the life of the mine as <br /> wetland habitat. <br /> Stages 1 and 2 will be backfilled, over the life of the mine, with wash fines from the <br /> sand and gravel processing plant. Wash fines will be pumped from the processing plant to Stages <br /> 1 and 2 and used to backfill each of the cells that comprise these stages. The goal of the <br /> reclamation plan for Stages 1 and 2 is to enhance the overall wildlife habitat diversity of the <br /> South Platte floodplain . <br /> Stages 4-7 will be reclaimed for developed water storage. Preliminary calculations indicate <br /> that approximately 7,500 acre-feet of water storage will be created in these four stages. <br /> 6.2 Reclamation Measures—Material Handling <br /> Site reclamation measures are illustrated on Exhibit F. Reclamation of the site will include <br /> creation of four bentonite slurry-sealed pits. All pit walls will be re-graded using stockpiled <br /> overburden. Pit perimeter slopes will be no steeper than 3H: IV. Topsoil will be spread over the <br /> surface of the re-graded slopes in all areas above the post reclamation water storage elevation, <br /> and the topsoil-covered surfaces will be re-vegetated. <br /> 7 <br />
