EXHIBIT E <br />Reclamation Plan <br />Post-Mining Land Use <br />The majority of the site is within the 100-year floodplain of Boulder Creek. Weld County <br />Department of Planning Services considers land located in the 100-year floodplain to be <br />suitable for agriculture, recreation, and wildlife uses. The post-mining land use as <br />proposed in this Reclamation Plan consists of open water for recreational purposes and <br />wildlife habitat. The open water created will consist of two unsealed ponds, approximately <br />30 and 14 acres. The remaining area, approximately 11 acres, will be vegetated to provide <br />wildlife habitat. These uses are compatible with the surrounding land uses and with the <br />Weld County planning goals. <br />Lafarge West, Inc. will concurrently reclaim pit wall areas in locations where mining has <br />been completed, according to phases outlined in the Mine Plan. Reclamation, including <br />regrading and seeding, will be completed in 2 to 5 yeazs following the completion of <br />mining operations. The mining will leave no highwalls on the property. No acid forming <br />or toxic materials are used or encountered in the mining. There will be no auger holes, <br />adits, or shafts left on the site. <br />Reclamation Measures -Material Handling <br />Site reclamation measures are illustrated in Exhibit F. Reclamation of the site will include <br />the creation of unsealed ponds. All pit walls will be re-graded with stockpiled overburden. <br />Slopes within 5 feet above to 10 feet below the post-mine water level will be no steeper <br />than 3H:1 V. Topsoil will be spread over the surface of the re-graded slopes in all areas <br />above the post-mining lake level; all topsoil-covered surfaces will be revegetated. <br />Disturbed areas associated with site access and the conveyor will be scarified, covered with <br />topsoil, and revegetated. Topsoil will be replaced, where required, in reclaimed areas at a <br />depth of approximately three to six inches. <br />Site grading will be performed to create stable topography that will be consistent with post- <br />closureland uses. Reclamation quantities and costs are summarized in Exhibit L. <br />Water <br />Overburden and mine materials will be inert and impacts to local surface water or <br />groundwater quality aze not anticipated to occur as a result of the development or <br />reclamation of the proposed expansion area. Lafarge West, Inc. will comply with all <br />applicable Colorado water laws and all applicable Federal and State water quality laws and <br />regulations. <br />Duckworth Pit <br />OMG //2 Permit <br />Page /U of 45 <br />
