The area to be mined lies between County Road 21 and the South Platte River, straddling 32 . 5 Road and lies within the Town of Platteville, Colorado . GENERAL INFORMATION The primary commodities to be mined are sand, gravel, topsoil, overburden, and borrow materials . No incidental commodities will be produced at this mine . Throughout this application we will refer to the two areas, (a) the south area containing Phases 1 & 4 and (b) the north area containing Phases 2 & 3 . The roadways (transportation corridors) are left out of the permit since L.G. Everist, Inc. does not own them. Permit/affected lands and mining lines and setbacks vary throughout the site, depending on ROWS and proximity to the South Platte River. Along the river the permit/affected lands line is 100 feet from the western bank of the river. Along the river in Phase 2 (north of CR 32 . 5) , mining will take place within 300 feet of the river bank and the bank will be rebuilt so the top of the slope into the reservoir area will be 300 feet from the top of the river bank. This will be done bV backfilling from the '/2h : ly mining face to the top-of-slope (TOS) line using shale from the floor of the mined area. Along the river in Phase 1 (south of CR 32 . 5) , the mining line will be along the west side of the old railroad grade, which is greater than 345 feet from the river bank. There is a 1305 feet section of reservoir bank in this area that will be armored since it is less than 400 feet from the river . MAP EXHIBITC-'I -MINING PLAN shows the location of the armored sections . Along the County and Local Roads, the permit lines use the ROW lines associated with the roads .
