Section - 2.053
(DD continued) primary coal stockpile area and the East Yard area may be used in the future
for storage of mine supplies, temporary stockpiling of coal refuse, mine development waste
and emergency coal storage.
EE. Non-Coal Waste Collection Areas -Several areas axe provided fox temporary collection of
non-coal wastes including a solid waste collection area in the East Yaxd and Elk Creek portal
area, and a scrap metal collection area near the old shop, Additional details on solid waste
collection, storage, and disposal are provided in the subsequent coal mine waste section.
FF. Non-Coal Waste Pickup Bin -Non-coal solid waste from other temporary collecdou areas is
transferred to and stored in the bins fox pickup and oEE-site disposal in the Delta County
Landfill or other suitable disposal site. The pickup bins axe three-sided steel bins with open
front and top so as to be readily accessible by collection equipment. Additional details on
solid waste collection, storage, and disposal are provided in the subsequent coal mine waste
section.
GG. Soil Storage Areas -There were previously two areas where soil materials were stored for
future reclamation use; the East Yaxd and the Elk Creek soil stockpiles. In conjunction with
mine expansion activities in 1997-1998, the Elk Creek stockpile was moved and expanded
and the East Yard and Elk Creek stockpIles were consolidated. With development of the Elk
Cteek IVGne and construction of associated surface facilities, the North Elk Creek soil
stockpile was established and all soil in the existing Elk Creek soIl stockpile was transferred
to the new stockpile. Additional details on soil material handling and storage axe provided in
the subsequent soils handling section.
HH. Elk Creek Culvert - In conjunction with the historic Somerset Mine C Seam mining activities,
U.S. Steel placed approximately 800 feet of 9-foot diameter culvert in the Elk Creek drainage
channel and backfilled over the culvert to create a level facilities area near the mouth of Elk
Creek Canyon. OMLLC has subsequently extended this culvert another 650 feet to
accommodate progressive mine expansion activities. The culvert has been sized, bedded,
placed, and backfilled to assure it's long-term stability. The Elk Creek culvert is designed to
safely pass the peak Elows resulting from a 100-year, 24-hour storm event and is permitted
under applicable provisions of Nationwide Permi[ 26 by the U.S. Army Corps of Engineers
(Permit No. 199675449). OMLLC also culverted two additional segments totaling
approximately 1,600 Eeet of the middle portion of Elk Creek in order to establish a haul road
and facilities pad fox the Elk Creek Mine.
II Elk Creek Canyon Road -The Elk Creek Canyon road was apre-law road extending from
the main haul road part way up Elk Creek Canyon. The lower portion of this road was
modified and improved a short distance beyond the Elk Creek Facilities area in conjunction
with previous mining-related activities. Expansion of the Elk Creek coal stockpile in 1997-
1998 cut-off access to this road at the lower end of Elk Creek Canyon. Access was
reestablished by a light-use road extending from the Cemetery up the west side of Elk Creek
Canyon to tie-in with the existing road. OMLLC modified this light-use road and the middle
portion of the Elk Creek Canyon road as a haul road to access the Elk Creek Mine facilities
and operations. Additional detail on this road is provided in the subsequent roads section.
JJ ID. Signs (Rule 4.02) -Mine and permit identification signs are displayed at each entrance to
the permit azea from public roads.
