The explosives area at the Foidel Creek Mine was transferted from the Mine No. I, Mine No. 2, and
Eckman Park mine, Permit No. C-81-071. Surface blasting is limited to 5 pounds of explosives. No
specific approvals are granted under this section.
VII. Disposal of Excess Spoil
No excess spoil exists at the Foidel Creek Mine. No specific approvals are granted for this section.
Vill. Coal Mine Waste Banks
Technical Revision No. 21 (TR-21) approved a coal waste pile south of Pond D at the main facility area of
the Foidel Creek mine. The pile configuration is a sidehill design with a maximum estimated volume of 3
million cubic yards of waste. The source of the waste is a prep plant which processes any low quality coal
product produced by mining. The Division approves the design and any alterna[ive specifications as
represented in Exhibit 26A of the permit (4.10.1(1)).
IX. Coal Mine Waste
Coal Mine Waste Fire Fighting Plan is found in Exhibit 25a of the permit (4.1 l.l).
No coal processing waste will be returned to abandoned workings at the Fish Creek Mine or Fish Creek
Tipple (4.11.3).
Twentymile Coal Company has previously been approved to dispose of select non-coal waste in a location
south of the area 1 pit. This location is located in spoil material from the Energy Mine No. 1, and is
located above the water table (4.l l.4(l}(3)).
X. Backfilling and Grading
The Foidel Creek mine portals are located along Foidel Creek, faced-up in highwall from the adjacent
surface mining activity in Eckman Pazk. Partial backfilling and grading was done to help seal the portal
area from groundwater inflow. The remaining backfilling and grading will occur at the completion of
mining activity at the Foidel Creek mine. No specific approvals aze granted under this section.
XI. Revegetation
The Division has previously approved the use of introduced species in the reclamation seed mix.
Introduced species are included in the pastureland and rangeland seed mixes. The applicant has
submitted information which shows that the introduced species are desirable and necessary to
achieve the approved post-mining land use, and are not poisonous or noxious, (4.15.2).
Methods to measure herbaceous cover and production, species diversity, and woody plant density
are discussed beginning on pages 2.04-52 and 2.05-I IS of Vol. 1 for all but the Fish Creek Tipple
area. These techniques include:
a) ten-meter transects using a ten point optical frame every one meter for a total of l00 "hits" to
evaluate vegetative cover;
b) clipping of cone-square-meter quadrant followed by drying far 34 hours at l05 degrees and
weighing to the nearest O.l gram for productivity;
