EXHIBIT E RECLAMATION PLAN The Loloff Pit is an operational sand and gravel mine, with this application being for the expansion of the existing mine boundaries to include approximately 4.24 acres of additional mining area. The site is approximately 55.17 acres with 42.7 acres currently permitted under Permit M-1985-112 on file with the Colorado Division of Reclamation Mining & Safety. Exhibit F shows the intended Reclamation Plan Map for the Loloff Pit. It is the operator's intent to apply all of the vegetation and re -grading requirements set forth in the original mine permit with some minor changes. The original permit does not call out water storage as an end use and did not account for a slurry wall to be constructed as part of the reclamation plan to allow for the water storage as an end use. With this amendment submittal, there are bonding calculations to include the estimated cost for constructing the slurry wall. Water storage is a consistent use for post mining operations and would be consistent with State and Local land use programs. The affected area in the amended mine area will be re -graded to the final reclamation grades with a GPS controlled D6 Caterpillar dozer. All reclaimed slopes to be re -vegetated, shall be re -seeded per the attached seed mix provided by the Greeley NRCS Field Office. All disturbed area slopes will be graded to a final slope no steeper than 3H:1V and all final slopes within the reservoir will have final slopes from the reservoir crest to the toe of slope of 3H:1V and the final reservoir bottom grade will vary from 2% to 0.5% to the sump. All reclaimed slopes from five (5) feet below the maximum water surface elevation of the reservoir and disturbed areas surrounding the reservoir shall be reseeded with the proposed mix design provided by the Greeley NRCS Field Office. The current reclamation plan requires 6 to 12 inches of topsoil placement within the 100 -yr floodplain and 18-24 inches of topsoil placement outside of the floodplain. There is not a stockpile for topsoil currently, however, the area to be included in the amendment shall provide topsoil for the reclamation. No irrigation system proposed as a part of the reclamation plan. Reseeding shall occur during the recommended planting periods of November 1 to April 30. The additional area to be re -vegetated with the approval of this amendment is approximately 4.24 acres. The schedule for the completion of the Reclamation Plan is estimated to begin within the next 18 months as mining operations have been ongoing and if market conditions maintain the current pace, mining should be completed in the next 36 months. With the installation of the slurry wall, the slopes that have not been regraded to the final 3H:1V slope where mining has extended to the mine limits, will be final graded and then reseeded with native grasses. The south wall, the west wall, and a portion of the north wall, have been mined to the mine limits and could be graded and seeded if the slurry wall
