Coal Company under Permit C -81 -071. Design and certification information for these facilities, as shown on
the Surface Facilities Map, Map 24, was transferred from Permit C -81 -071 and incorporated into TCC's permit
(the explosives bunker located to the south of the tipple facility was also transferred to TCC).
• The tipple /loadout facilities include the Run -of -Mine (ROM or "Belt- Out - Back ") stockpile, truck dump,
crushing facilities (primary & secondary), conveying facilities, sampling facilities, finished product (Tipple)
stockpile, stoker belt and dump, stoker product stockpile, conveyor belt and stacker for coal stockpile, train
loadout, and trackage, and access and temporary storage site for cleaning spilled coal from loadout tunnel. Of
the above structures (as discussed in the following sections), the following are identified as existing structures,
transferred from Permit C -81 -071:
Structure Dimension (LxWxH)
Raw Coal Conveyor 126' x 10' (dia)
ROM Coal Conveyor 168'x 10' (dia)

Overland Conveyor Geotechnical Investigations (MR11 -254)
Site geotechnical investigations are required to support evaluation, design, and possible future construction,
operation, maintenance, and reclamation of an overland conveyor which would transfer coal from the Sage
Creek Mine to the Twentymile coal handling facilities. Appropriate environmental clearances for the proposed
geotechnical investigations have been completed, as documented by a cultural _resource survey report (Exhibit
6T, Overland Conveyor Cultural Resources Information), and a wildlife consultation letter (Exhibit 23B,
Overland Conveyor Wildlife Consultation).
As a result of conceptual design evaluations, a 25 -foot wide conveyor corridor, approximately 8 miles long,
extending from the Sage Creek portal area to the Twentymile coal handling facilities, has been defined, as
shown on Figure EX49X -F1 in Exhibit 49X, Overland Conveyor Design Information. Approximately 2.7 miles
of the conveyor corridor fall within the Sage Creek Coal Company (SCCC) Permit Boundary. The remaining
5.3 miles are within the Twentymile Permit Boundary. As proposed, the overland conveyor, and a light -use
construction and maintenance service road would fall within this corridor.
The site geotechnical investigations will provide foundation and soils information for evaluation and design of
support structures for the proposed overland conveyor. Site geotechnical investigations for the proposed
overland conveyor will involve completion of 35 to 40 shallow (approximately 10 -30 foot deep) geotechnical
test holes along the length of the corridor. An all- terrain drill rig will be used to complete 4 -inch hollow -stem
auger sample holes to characterize foundation materials, assess depth to bedrock and groundwater conditions,
