EXHIBIT E <br />Reclamation Plan <br />Post-Mining Land Ilse <br />Portions of the site are within the 100-year floodplain of Idaho Creek. Weld County <br />Deparhnent 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. The <br />open water created will consist of two unsealed ponds, approximately 30 and 14 acres. The <br />remaining area, approximately 11 acres, will be vegetated. These uses aze compatible with <br />the surrounding land uses and with the Weld County planning goals. <br />Lafarge West, Inc. will concurrently reclaim pit wall azeas 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 years following the completion of <br />mining operations. The mining will leave no highwalls on the property. No acid forming <br />or toxic materials aze 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 aze 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 />to form slopes no steeper than 3H:1 V. Scrapers will be used to place the backfilled <br />overburden and topsoil. Using scrapers to layer the lifts at a 3:1 slope ensures a stable <br />configuration. Topsoil will be spread over the surface of the re-graded slopes in all azeas <br />above the post-mining lake level; al] 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 azeas at a <br />depth of approximately six to twelve inches. All Bankard Sandy Loam located east of <br />Idaho Creek will be completed salvaged in stockpiles for topsoil replacement. <br />Site grading will be performed to create stable topography that will be consistent with post- <br />closure land uses. Reclamation quantities and costs aze 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 azea. 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 />DMG !/2 Permit <br />Page 1 / oj49 <br />
