r. The operation produces aggregate to meet particular construction specifications. Water used to wash the gravel will continue to be drawn by pump from a series of sump wells at various locations shown on the mining map, Exhibit "C" . After washing gravel , the water is piped along the southern boundary of the pit into the settling pond also shown on the mining map, Exhibit "C" . From there it will filter back into the subsurface stratas. No water from the mining operation will be dis- charged into surface waters, and no pollution of any subsur- face or ground water should occur. B. The Crusher Plan: The crusher which will process the sand and gravel removed from the pit is generally located in the work area originally shown as Phase I on the mining map, Exhibit "C" . The operator proposes to move the location of the crusher from time to time closer to cutting operations for conveni- ence as the mining operation moves westward. An alternate western location is shown on Exhibit "C" submitted with this application. The crushing equipment generates a tolerable level of noise and, in any event, will at all times be within the confines of the Eagle River, the Denver & Rio Grande Railroad, and U. S. Highway 6 & 24 . Complaints have been received from the Eagle River 1978 Trust about noise, particularly the safety backup signals required by OSHA; however Eagle County has determined that the operation does not violate applicable noise regulations. Moreover, the operator has placed stock- piles so as to create an earth berm to screen the noise from his work area, and the proposed movement of mining operations westward is expected to alleviate the situation so far as the Trust is concerned. The western crusher location shown on Exhibit "C" is particularly well suited to insulate the noise because of the present highwalls of the area. -3-
