Exhibit E -Reclamation Plan <br />Backfilling and reclamation activities will require an additional three to five years after mining is <br />completed. As much as 1.5 million cubic yards of material from the WSF excavation may be used <br />to develop the final topography, with a maximum elevation of 5,016-feet AMSL to the east along <br />Brighton Road. The site will slope gently east to west towards the South Platte River as shown on <br />Exhibit F-2. No pit walls are anticipated. No off-site fill material will be required. If the <br />Division were required to reclaim Expansion Area North, then only filling to two feet above the <br />groundwater level as described in Reclamation Plan A would be necessary. Adequate material is <br />available onsite to accomplish the minimal filling required. <br />Expansion Area South <br />Mining Area <br />Expansion Area South will be mined after the Expansion Area North is mined out, depending on <br />market conditions and the quality of the material (Exhibit F-1). Before any disturbance occurs <br />within the Expansion Area South, this permit will be modified by a Technical Revision to include <br />the mine and reclamation plan and bonding for this area. <br />REVEGETATION PLAN <br />The primary goal of the revegetation plan is to establish a diverse and long lasting plant cover <br />that is capable of self-regeneration without irrigation. Historically, vegetative cover in the area is <br />less than 5 percent and consists mostly of annuals and perennial grasses. Drought tolerant species <br />will be used to establish vegetation cover best suited for the intended post mining land uses. <br />Revegetation at the existing Worthing Pit, Expansion Area North and Expansion Area South will <br />be consistent with industry practice and the Colorado Reclamation Board standards. Standard <br />Best Management Practices (BMPs) and field-tested methods will be implemented during <br />reclamation activities. <br />Topsoil Stockpiles and Replacement <br />Topsoil in the Expansion Area North is minimal due to historic mining activities. Most topsoil in <br />the Expansion Area North was previously stripped and no longer exists on the site. However, <br />approximately 35,000 cubic yards of topsoil is stored within the stockpiles at the Worthing Pit. <br />Not all this stockpiled topsoil will be required for reclamation of the existing permitted mine <br />because the pit lakes will not require revegetation except for the shorelines. Excess topsoil from <br />Worthing Pit may be used for revegetation at the Expansion Area North_ Detailed information is <br />available in Exhibit I. <br />Based on historic, topographic and hydrologic conditions, the topsoil at the site is anticipated to <br />be poorly suitable for revegetation. Sorting and testing are required prior to distribution to <br />determine if soil enhancement is necessary for revegetation. Topsoil will be applied by truck and <br />shovel, and graded to an average depth of six to nine inches, depending on availability. <br />If topsoil stockpiles are left undisturbed for more than one year, a cover crop of Western <br />Wheatgrass will be planted on the stockpiles at a minimum rate of 3 pounds of pure live seed per <br />100 square feet. <br />1898-Frei ] 12 Exhibits_(4.20.05).doc E-5 <br />
