redistribution when available, contour furrowing, and seeding. All roads requiring total <br />reclamation were completed in 1996. <br />The facilities azea pond was regraded in 1996. The pond had been utilized to treat runoff <br />from the upper mine facilities, which will now be treated by the Center Ridge pond. <br />Since the Center Ridge, West Ridge, and Moffat ponds aze approved as permanent <br />structures, only the Tipple area ponds remain to be reclaimed. Reclamation of the Tipple <br />ponds will be delayed until the disturbed azea draining to [he pond no longer produces <br />sediment in excess ofpre-mining levels or that of adjacent undisturbed azeas. <br />Surface and groundwater aze monitored and a mitigation plan for potential impacts has <br />been proposed. Surface runoff from disturbed areas is channeled to sedimentation ponds <br />located in each of the West Ridge, Moffat, Center Ridge and facilities azeas, and through <br />a series of four ponds in the tipple azea. Surface water is monitored upstream and <br />downstream of the mine in Trout Creek, as well as at sediment pond discharge points. <br />Groundwater is monitored down-gradient from the mining operation in spoil, in Trout <br />Creek alluvium, and in the Trout Creek sandstone. With the exception of the Moffat, <br />Center Ridge, and West Ridge ponds, all treatment and monitoring structures will be <br />reclaimed when their use is no longer warranted. <br />Water has not been used on the mine since reclamation operations were lazgely <br />completed. Water was obtained from a pump station located in Trout Creek. The <br />operator received approval for the pump from the Army Corps of Engineers. Pittsburg & <br />Midway has obtained rights for all water usage at the operation. Details concerning water <br />rights are located in Section 3.6 of the permit application. <br />Etlna Mine 10 Permit Flenewal No. 4 <br />
