Section - 2.05.3
from the Elk Creek Mine surface facilities disturbance area, in a new soil stockpile
• constructed on the east side of Elk Creek, near the northern limit of the new mine
disturbance area. Surveyed stockpile volume is approximately 59,500 cubic yards
(18,600 cy from relocated Elk Creek soil stockpile, 40,900 cy soil salvage from Elk
Creek Mine dismrbance areas). Compliance with applicable design and stability
requirements is addressed by the Slope Stability Analysis for Elk Creek Mine Portal
Bench Fills and Soil Stockpile (Montgomery Watson, 2000). Additional details on soil
material handling and storage are provided in Section 2.05.3 under the sub-heading,
"Soil Materials".
Roads
Designs and as-built configurations for all mine roads effect compliance with applicable provisions of
Rule 4.03 and 4.04. Specifications for each road aze summazized or referenced in the following
sections. Uriless specifically discussed or referenced, alternative specifications are not necessary since
road designs comply with applicable regulatory standards. In those limited aeeas where alternative
specifications are necessary due to cut or fill requirements, geotechnical stability considerations aze
addressed by discussion or reference. Because those roads requiring certification per Rules 4.03.1
(1)(d), and 4.03.1 (f)(i) aze components of lazger construction projects, road certifications are included
in Exhibits 2.05-E2, Geotechnical Design and Stability Analyses and 2.05-E4, Mine Development
Waste/Coal Refuse Facility Design. Any alteration or relocation of natural drainages and
requirements for inlet/outlet protection for road culverts in conjunction with road construction
requirements is addressed in the subsequent sediment control section. The only scream ford which
exists on any mine road is an existing Ford on the Elk Creek/Hubbazd Creek powerline road as
discussed under the description of this road.
• Portions of the main entrance, Sanborn Creek Mine, and West Valley haul roads and other roads aze
within I00-feet of the outside right-of--way line of State Highway 133. By letter dated Febmary 28,
1991, [he Colorado Depaztment of Highways provided Somerset Mining Company with percussion
for the proposed perrtut area and associated roads within the permit azea to be within less than 100
feet, measured horizontally, of the highway right-of--way. In addition to the required Highway
Department approval; all mining and related activities will be conducted within the permit azea on
private and public lands where the public has never had access or where public access has been
limited; the Union Pacific Railroad right-of--way, tracks, and related facilities lie between the mine and
the highway; and the proposed mining and related activities should not adversely impact public
interests.
Because those roads requiring certfcation per Rules 4.03.1(1)(d) and 4.03.1(f)(i) aze components of
larger construction projects, road certifications aze included in Exhibits 2.05-E2, Geotechnical Design
and Stability Analyses, and 2.05-E4, Mine Development Waste/Coal Refuse Facility Design.
Mine Entrance Haul Road -The entrance road which runs from State Highway 133 to the Elk
Creek coal handling, support, and ancillary facilities azea, is classified as a haul road since it is utilized
for track haulage of coal to and from the mine. For purposes of chazaccerization and discussion, this
road can be segregated into four segments. For all road segments, road width and grade are
appropriate for [he volume of [raffic and weight and speed of vehicles that use the road as indicated
by safe operation and minimal maintenance over a period of many years. The speed limi[ for this and
all mine roads is 15 miles per hour and the road is designed and constructed to provide a minimum
turning radius of 50-feet. The entire road is within the mine disturbance area as defined by Rule
4.05.2(4) and many of the performance standards under Rule 4.03 are, therefore, not applicable. Road
• plan and profile configuration is shown by a Facilities Detail Map, (Map series 2.05-M3x).
The first segment of the mine entrance road begins at the edge of the right-of--way for State Highway
133, crosses over the railroad right-of--way, passes on the uphill side of the coal storage silo, and
