West Elk Mine
surface shop building but has not yet been built. It will be utilized to perform maintenance on the
larges surface equipment. As -built descriptions of the surface shop facilities are provided in Exhibit
68.
Materials Storage Bench Building
Construction of the Materials Storage Bench Building was completed in March 1996. The
building is utilized to store materials that will be used in the mine. The 3,900 square foot
building has six bays. The as -built description is provided in Exhibit 68.
Bulk Fuel, Barrel, and Hydraulic Component Storage Areas
MCC stores bulk petroleum products within a covered, concrete bunker capable of containing
approximately 31,000 gallons. Barrels containing petroleum products or waste materials are stored
within a separate covered containment area of approximately 1,840 square feet located between the
bulk fuel area and the Maintenance Shop. These storage areas are enclosed by three walls and a
roof to reduce the accumulation of precipitation within the concrete bunkers. The material stored in
this area includes products, recyclables, and hazardous wastes.
Petroleum products are stored for ongoing operations and maintenance usage. Recyclables are
collected and transported off-site and hazardous waste is also transported off-site. See the Spill
Prevention, Control and Countermeasure Plan in Exhibit 8 for more detailed information
regarding the fuel storage area containment. The bulk fuel storage area also includes a heated,
enclosed storage bay for a total storage area of approximately 3,500 square feet. To the west of
the heated, enclosed bay is the hydraulic components storage building. This 450 square foot,
steel structure provides containment and cover for hydraulic components, motors, etc. being
stored prior to return to vendors. An as -built construction description is provided in Exhibit 68.
Oil Separation Skimming System
The oil separation system consists of an oil skimming pit and an oil skimmer. The skimming pit is
contained in the shop building and receives water from wash down bays and the shop. An oil
skimmer unit is installed in the skimmer pit and removes the bulk of the oil which may accumulate
on the water. The remaining water is tested for water quality compliance and drained to the mine
site sediment ponds and/or is pumped and hauled to an authorized disposal facility.
Bulk Rockdust Bin and Compressor Building
MCC utilizes a bulk rockdust storage and distribution system at West Elk Mine. The bulk rockdust
bin has a capacity of approximately 142 tons. The compressor, distribution tank and controls are
contained in a 416 square foot building at the base of the bulk storage bin. An as -built construction
description is provided in Exhibit 68.
Water Treatment Plant
A water treatment plant at the mine site provides potable water for the operation. The Culligan
Multi -Tech 48 water treatment system can treat water at the rate of 62 gpm. Thus, maximum
capacity is about 89,280 gallons of treated water per day. The water treatment plant is operated as
