Substations 2 and 3; and a mine water treatment pond. The Sanbom Creek Mme facilities are
being utilized in conjunction with ongoing muting operations of the Sanbom Creek Mule.
• OMI's phased mine expansion includes at least three distinct phases; 1) Installation of a longwall
muting system and associated coal handling, waste handling, and support facility modifications and
upgrades; 2) Cortswction of the required infraswcture for the Elk Creek Mme in the D Coal Seam
and initial mine development; and 3) Development and longwall mining in the Elk Creek Mute. The
follOR'Illg S~~mm~n>PS those mining-related surface facilities and disturbance auras within the mine
permit area recently constructed, currently being conswtted or developed, or which will be
constructed or developed in the future in conjunction with the phased mine expansion:
Sanbom Creek Mme and Elk Creek Coal Handling, Support, and Ancillary Facilities
Expansion -The initial mine expansion activities have included installauon of ahigh-capacity
longwall mining system in the Sanbom Creek Mme; relocation of the existing storage
buildings, Substation No. 1 and a portion of the existing powerline; modification of the
existing overland conveyor, dump station, tipple, silo feed conveyor, silo, and loadout; and
conjwction of a new office, warehouse, sanitary leach field, two stacking tubes, a reclaim
system, a screening facility, a new batch weigh loadout, and a new coal mine waste pile and
associated haul road.
Elk Creek Mme Construction and Initial Development - Constmttion and initial mine
development for the new Elk Cmek Mme will involve diversion of a portion of Ells Creek;
relocation and/or reconfiguration of the existing Elk Creek soil stockpile; upgrading of the
existing Elk Creek road; conjwction of mine portak, ventilation shafts, and associated
surface facilities; construction of a new conveyor connecting the portals to the existing coal
stockpile; installauon of mine dewatering and water handling facilities; and initial
development and mining of private D Seam coal reserves.
Ellt Creek Mme Development and Longwall Mmittg - OMI has apphed for a Federal Coal
Lease to mine extensive D Seam reserves to the north and west. Federal lease approval is
anticipated by June 2000. and mining of the D seam Federal reserves will be pemtitted
separately at some time in the future.
Potential environmental considerations associated with ongoing mining operauons, the phased mine
expansion attivities, and construction, mine development, and mining for the Elk Cmek Mme include:
1) Direct surface disturbance with temporary loss of vegetation and utilvation of these areas
during active operations. These areas will be reclaimed following completion of active
operations to their prettrinirrg use as "undeveloped ]ands" with vegetative cover and
productivity cornparable to that which existed prior to disturbance.
2) Indirect surface disturbance due to mining-related ground subsidence. Given the depth
of mining, surface subsidence effects are negligible and have not nor are they expected to
adverselyimpatt anyrenewable resources.
3) Surface disturbance is generally in or adjacent to roads or other areas of human use and
activity so distinct wildlife impacts ate minimal.
4) Surface water impatts ate very localized and are effectively addressed through
compliance with applicable regulatory requirements for drainage and sediment control
and effluent standards.
• 5) Significant ground water resources have not been identified within the mine permit area
and no identified water users will be impacted
