EXHIBIT E - Reclamation Plan a) Site stabilization and reclamation of mined out areas is mostly completed. Once the slurry wall is constructed, the remaining material in the East and West Pits will be mined and processed to make gravel for Weld County roads. It is expected that the mining operation will continue for another 3 to 5 years following construction of the slurry wall. Area A (11.64 acres) contains the Weld County Public Works salt shed, road grader training course, and the Weld County fueling site (jointly used by Weld County and Greeley). This area has been reclaimed to its final configuration as an industrial developed use and is requested to be released from the DRMS permit area. Area B (26.57 acres), the mitigation wetland constructed under supervision of the U.S. Army Corps of Engineers, has also been reclaimed to its final configuration and is request to be released from the DRMS mining permit. Area C (70.81 acres), the East and West Geisert Pits, are proposed for reclamation as developed water storage, stockpile area, and dust control well. There is also a walking path/bike trail along the north edge of the West Geisert Pit. Slurry wall installation around the East and West pits (54.32 acres) will commence upon receipt of approval of this Amendment request from the Colorado Division of Minerals and Geology. Following installation of the slurry wall around both pits, the site will be offered for sale to a local water provider (special district, town, or irrigation company). Final configuration and reclamation of the Geisert ponds will be dependent on the water storage design needs of the purchaser. The final water storage configuration will likely include inlet and outlet works, pumps and piping, fencing, walking/bike paths, and other water storage and handling engineered facilities. The most likely location for the future pump house has been shown on the Reclamation Plan Map (Exhibit F). b) Reclaimed slopes interior to the Geisert East and West pits will be graded at a maximum of three to one (3:1) horizontal to vertical or as approved by the Division upon submission of final water storage designs as proposed by the site purchaser/future water storage property owner. C) Reclaimed areas will be stabilized by: i) Re-grading on areas of the site where slurry wall installation has been completed. ii) Replacement of topsoil in thicknesses equal to or exceeding the original topsoil depths originally at the site. iii)Soil amendments, seed mix, and application rate to be determined in accordance with NRCS guidelines and Weld County Weed Control requirements. iv)Mulch application may be concurrent with seeding (hydro-seeding or drill and crimp). Mulch may include straw and tackifier. v) The existing Poudre River trail will be replaced if damaged during slurry wall installation. d) The Geisert mining access to H Street (see Exhibit C) will be left as-is following completion of slurry wall installation and cessation of mining for use by the future water storage property owner. e) Prior to slurry wall installation, the County's existing Geisert dust control well will likely need to be relocated outside of the proposed slurry wall boundary so that future water pumping may continue. The power line and associated poles servicing the Geisert well will be temporarily relocated. That power line services only the County's well. e) The Geisert site had little overburden materials, any overburden from the Geisert site has been utilized by Weld County Public Works Department for construction of local County roads and on other County construction projects. f) The slurry wall will cost approximately $2.8 million. The cost of the to-be-constructed water storage facilities (outlet works, pumps, meters, and piping, fencing) is unknown and will be completed by the future purchaser of the facility. Reclamation and seeding estimated costs: Under $30,000. M:\DAVE B\Geisert Pit\DRMS Permit Amendment\Geisert Amendment Application & Exhibits Revised 4-21-1 Ldocx
