roadway to allow the trenching machine to install the line from the staging area to the 100,000 gallon tank.
<br />Approximately 6,090 feet of line was installed, with a substantial portion of the total length associated with the
<br />segment of the waterline that parallels the access road.
<br />Given the inactive status of the Mines, electrical power was shut -off in 2013, and active dewatering and discharge
<br />ceased at that time. MCM plans to leave most of the buried waterline in place during final reclamation activities. The
<br />pump, pumphouse, fence, intake line, and powerline will be removed. The ends of the buried waterline will be
<br />partially excavated, cut -off three feet below the ground surface, plugged, capped, and backfilled.
<br />Wastewater Treatment Facility - Approval to construct a wastewater treatment facility was obtained from the
<br />jurisdictional regulatory agencies in 1982, and construction of the facility was completed in late 1982. The
<br />Wastewater Treatment Facility is located to the southeast of the shop between the railroad spur and the Williams Fork
<br />River. The main components of the treatment facility include a two -cell aerated sewage lagoon and polishing pond.
<br />Other components include an oil water separator, sewer lines from the bathhouse, shop, and laboratory, a lift station,
<br />and a discharge ditch. The discharge flows into the Williams Fork River and is monitored for compliance with the
<br />CDPS Permit. Under Temporary Cessation status, the Wastewater Treatment System is not currently being utilized,
<br />and any sanitary waste requirements for the site are addressed by contractor - serviced portable units.
<br />Red Rock Pit and Crusher Site
<br />The Red Rock Crusher site is located just to the east of the 5A Mine Portals. Rock from the Red Rock Pit was
<br />excavated and crushed at this location for use on underground haulage roads and surface access roads. Previously the
<br />crusher facility consisted of a constructed pad, truck ramp, hopper, gyratory crusher, and screens for sizing crushed
<br />rock. Presently, only the storage pad and road into the site exist, and all equipment has been removed.
<br />Explosives Storage Area. The Explosives Storage Area location is shown on Maps 25 and 26. Two portable
<br />magazines were used to store permissible powder and blasting caps for the limited blasting required for underground
<br />construction. Under the temporary cessation status, these portable magazines have been removed from the site.
<br />The old explosive storage area, located north of the red rock crusher site (for which a small area exemption exists,) has
<br />been reclaimed. Approximately 185 cy of stockpiled topsoil was spread to a depth of about 6 inches, and the site was
<br />re- seeded.
<br />Ancillary Facilities
<br />Ancillary facilities include miscellaneous light -use roads and storage yards, as shown on the Structures and
<br />Renewable Resources Map (Map 25).
<br />Construction drawings for many of these facilities were included in previous permit submittals (1983). Since these
<br />facilities are now in place and have been approved by the appropriate jurisdictional agencies, the drawings have been
<br />removed from the PAP.
<br />Coal Refuse Disposal Sites - The original coal refuse disposal site was approved, and initial construction
<br />commenced in 1983. The site was designed to accommodate haulage and disposal of all mine development waste
<br />and course reject from the mining operations. The engineering group of CTL- Thompson, Inc. designed and
<br />completed a geotechnical evaluation of the disposal site, as presented in Exhibit 21, Waste Disposal Site.
<br />Subsequent to completion of design and construction of this original site, the No. 9 Mine Disposal Area was
<br />designed and permitted, and has been used as the primary coal refuse disposal site.
<br />Historically, an estimated 20,000 cubic yards of waste material were produced per 1,000,000 tons of coal mined.
<br />The original waste disposal area and the No. 9 Mine Disposal Area have designed refuse capacities of 1,000,000
<br />cubic yards and 200,000 cubic yards, respectively. The combined capacities would accommodate the refuse from
<br />the production of approximately 60,000,000 tons of coal, or approximately 15 to 20 years of mining. When active
<br />mining ceased and the operation went into temporary cessation status, the No. 9 Mine Disposal Area was nearly at
