Overburden
Since EC is an underground mining operation, there is very little movement of overburden. Previous limited surface
mining activity is now abandoned and currently undergoing reclamation. Refer to Section 2.05.4 Reclamation Plan
for reclamation details.
Coal Handline Structures
A detailed discussion of the coal handling structures utilized at EC has been discussed previously in the Facilities
portion of this Section.
Coal Processine Waste and Non-Coal Processine Waste
All non-coal processing waste are to be disposed at the Moffat County landfill except sludge from the sandtraps and
bottom of EC's oiUwater separators. This material, which is largely dirt and refuse cleaned off mining vehicles and
shop floors will be tested for RCRA characteristics to assure it is no[ hazardous waste and then disposed of on the
approved refuse piles. Test results will be kept on file at EC. The material will be spread out and compacted at the
waste disposal sites with the underground development waste. It is estimated that EC produces between 10 and 40
yds. Per month of this material when in full production.
Underground Development Waste
EC produces underground development waste from two sources: rock ramps or boreholes between seams and coarse
reject from run of mine coal. EC both stores development waste underground in compliance with MSHA regulations
and ships material to the surface for disposal at approved waste disposal sites maintained in compliance with MSHA
and CDMG regulations. Rock slope material is transported to the surface on conveyors.
Although EC does not have a preparation plant, coarse reject waste rock is physically separated from the run of mine
coal at the SA Yard rock diversion chute or rotary breaker located at the screening and sizing building.
Currently, EC has two approved waste disposal sites. These sites are shown on the Structures and Renewable
Resources Map (Map 25). When operational constraints restrict immediate transfer of waste to the permanent
disposal sites it will be temporarily stored in the SA Yard at the locations shown on Map 26. A maximum of 3,000
cubic yards will be stored in the 5 A Yard. This material will then be transferred from the temporary storage areas to
the permanent disposal sites within 60 days. Problems resulting in additional time and storage volume will be
requested on an individual occurrence basis.
