Box 85, Cripple Creek, Colorado 13 phone 9 25 <br />Mine reclamation plan oaTe:February 23, 1981 <br />'Charles Brechtel pAOE 5 <br />Mulching 1 acre 250.00 <br />Total 8900.00 <br /> <br />The Carlton Tunnel site will disturb additional land. The existing <br />dump area will be used for settling ponds. The .new dump area should <br />have the top soil removed and stockpiled for later use. Because this <br />soil is deep, it will provide enough topsoil to help establish vege- <br />tation on the flatter area of the dump area. Care should be taken <br />when stripping the topsoil not to get into the present material and <br />large rocks. The new dump material will be left slightly flatter <br />than the angle of repose in order to. provide more stability of the <br />dump. <br />~A diversion will be used to safely convey runoff water away Prom the <br />settling ponds. This will prevent the settling pond from filling <br />with excess sediment and reduce the bhance.of an overflowing.of the <br />ponds. <br />Water coming down the main drainage past the tunnel will be. safely <br />controlled with the use of culverts or drop structures in the exist- <br />ing channel. <br />The water from the tunnel will be routed through the settling ponds, <br />with a drop structure letting water into the existing drainage. <br />Once the plan end location of the proposed settling pond is prepared, <br />some effort can be saved by applying top soil to the top area of the <br />dump. This will eliminette double hauling and stockpiling of the top- <br />soil. The'soil can be placed on those areas that will not be used <br />in the current mining operations. <br />Reclamation of the area has been discussed previously, but will also <br />include grading and shaping, fertilizing, seeding and mulching. <br />Seeding, fertilizing, and mulching rates for this area are included <br />on one of the CO CONS 6 forme. The total area for this work will be <br />about 3 acres. <br />Estimated Cost for Carlton Tvnnel Site (1981 cost} <br />Topsoiling 3 acres 81500:00 <br />Shaping 3 acres 1200.00 <br />Fertilizer 3 acres 150.00 <br />Seed and Seeding 3 acres 300.00, <br />Mulching 3 acres 65.00 <br />Total 8382$.00 O <br /> <br />i~h4392 <br />
