~ Ill IIIIIIIIIIIlIIII ~~ <br />EXHIBIT "B" 5!J <br />This material is removed by first removing considerable soil over- <br />burden on a six (6) to eight (8) foot wide area, then catapillar tractors <br />begin to push the underlying gravel down a 30 - 35% slope to the loader <br />and crushers below. As that rench of gravel is removed, the overburden <br />alongside is then similarly pushed onto the mined are and a new trench <br />is opened for removal of gravel when the pit is exhausted, the soil would <br />be evenly re-distributed and shaped on the site for reclamation. <br />The present topsoil at the site has been stockpiled in an area where <br />former mining has taken place, and has filled up a depression caused by <br />erosion and former extraction activities. <br />There currently exists a highwall consisting of soil overburden and <br />gravel. As this pit is worked from the East to the West it is anticipated <br />that the mining would continue until the operator intersected a draw behind <br />the existing highwall. This would have the effect of eliminating the highwall <br />once it was mined out, and would allow for the creation of advantageous slopes <br />for reclamation. <br />The areas distrubed at any one point in time wou]d be approximately 2 <br />to 3/4 of an acres, with the total effected acreage being 8.5 acres. Production <br />usually begins in early summer and continues for 55 - 60 days in duration, during <br />which time approximately 30,000 to 35,000 yards of material are extracted. At <br />this rate of production it is anticipated that the pit will last until 1988. <br /> <br />AU G 21 1978 <br />MINED LAID RECLAiv"~Ai~O~ <br />Colo. Dept. of Natural Resources <br />
