-39- Bonanza Power Plant in Vernal , Utah. A 40,000 ton capacity coal storage facility is located approximately .3 miles south of the rail loadout along the overland conveyor route. Coal processing waste generated by the wash plant facility is trucked approximately 3.6 miles to the refuse disposal area located east of the rail loadout in the northern portion of the permit area. The refuse disposal area is comprised of nine separate subareas to be sequentially developed and reclaimed over the life of the operation. Non-coal solid wastes are disposed of at the Halandras garbage dump situated within the northwest portion of the permit area along County Road 65. Ventilation for the mine workings consists of a fan facility at the D-Portal area and a passive ventilation facility situated at the old Staley-Gordon mine site near the mouth of Scullion Gulch. Water supplies for the mining operation are obtained from an alluvial well pumping facility located at the confluence of Scullion gulch and the White River along County Road 65. Electrical power for the mining operation is provided by a 13.8kv H-frame powerline leading to the D-Portal from a substation near the alluvial well field. The operation is in compliance with the requirements of this section. XVI.
