Loveland Ready-Mix Concrete, Inc. <br /> M1974-069 AM03,TR 1 April 6, 2020 <br /> EXHIBIT E -Reclamation Plan <br /> The following information pertains to the Colorado Division of Minerals and Geology Permit # <br /> 1974-069 for Loveland Ready Mix Concrete, Inc.; Larimer Pits. <br /> The general plan is unchanged. The strategy is to leave a series of open meadows, wetlands, and <br /> ponds interconnected by landmasses,for roadways,open areas,and areas for camping,hiking,and <br /> fishing. Natural grasses will be established that do not need irrigation. The anticipated size of <br /> each remaining pond is shown in Exhibits C-1 and F-1. The majority of the site has been mined <br /> out, however pond sizes may vary at the end of mining and reclamation as long as they do not <br /> exceed the allowable exposed groundwater surface areas identified in state approved <br /> augmentation plans 00CW142 and W-7412. The reclamation time schedule correlates directly with <br /> the mining time schedule contained in Exhibit D. <br /> Reclamation will occur concurrently with mining, and final reclamation of each cell is completed <br /> as the mining operation moves to the next cell. In addition, reseeding will be done in twelve- <br /> month intervals for dust control. Therefore, any areas that need seeding and are not involved in <br /> the mining operation will be reclaimed in approximate 12-month intervals. All overburden/topsoil <br /> will be stockpiled no more than 250 feet from where it will be placed for final reclamation. <br /> At each pond,the first 4 to 6 feet from finished grade to the expected water line will be sloped at <br /> a ratio of 3:1 and to 10 feet below the water line. The remaining slope to the bottom of the pit will <br /> have a maximum slope of 2:1. <br /> Cell 21 will be reclaimed as a dry cell with pasture grasses. However, it could be used for <br /> stormwater storage or water storage. If reclaimed as a dry cell the sides will be sloped at a ratio <br /> of 3:1 to the bottom of the cell (See the pit bank cross sections on Exhibit F-2).If it is determined <br /> that it will be used for stored water prior to lining, the sides will be sloped as described for ponds <br /> above. The maximum anticipated depth of Cell 21 is 24 feet. Six inches of topsoil will be spread <br /> along the sides and bottom and leveled with a motor grader prior to plowing, harrowing, and <br /> reseeding. No additional topsoil will need to be imported to the site to achieve the required slopes <br /> and soil depth. <br /> After Cell 21 has been mined, an approximate 15 acre pit will be lined with a clay wall and <br /> reclaimed as described above. Clay material for lining the pit will come from the site, no lining <br /> material will need to be imported. An approximate 55,000 cubic yards (c.y.) of acceptable clay <br /> material will be needed to complete the liner. It will come from mined overburden and from the <br /> west side of the site. <br /> Cell 21 will be lined in accordance to State Engineer Guidelines for Lining Criteria of Gravel Pits. <br /> The Proctor Curves and Permeability Tests for the liner material to be used are attached as Exhibit <br /> I . The engineering design is also attached in this section, and meets the State Engineer Design <br /> Standard to prevent leakage no greater than 0.03 ft3/day/ft2. <br /> Appropriate quality control observations and testing will be performed during construction of the <br /> liner and written documentation of the work performed and results of all quality control field and <br />
