V1. Use of Explosives <br />The explosives area at thz Foidel CreeR Mine was transferred tom the ~~line ho. I, ~(ine No. ?, and Ec:;n;a^ <br />Park mine, Permit No. C-31-071. Surface blasting is limited to ~ pounds of explosives. No specific approvals <br />are eranted under this section. <br />VI1. Disposal of Excess Spoil <br />No excess spoil exists at the Foidel Creek Ivtine. No specific approvals are granted for this section. <br />Vlll. Coal Ivtine Waste Banks <br />Technical Revision No. 21 (TR-21) approved a coal waste pile south of Pond D at the main facility area of the <br />Foidel Creek mine. The pile configuration is a sidehill design with a maximum estimated volume of 3 million <br />cubic yards of waste. The source of the waste is a prep plant which processes any low quality coal product <br />produced by mining. The Division approves the design and any alternative specifications as represented in <br />Exhibit 26A oY the permit (4.10.1(1)). <br />IX. Coal Mine Waste <br />Coal Mine Waste Fire Fighting Plan is found in Exhibit 25a of the permit (4.l l.l). <br />No coal processing waste will be returned to abandoned workings at the FoidelCreek Mine or Fish Creek <br />Tipple (4.1 1.3). <br />Twentymile Coal Company has previously been approved to dispose of select non-coal waste in a location <br />south of the area 1 pit. This location is located in spoil material from the Energy Mine No. 1, and is located <br />above the water table (4.11.4(1)-(3)). <br />X. Backfilling and Grading <br />The Foidel Creek mine portals are located along Foidel Creek, faced-up in highwall from the adjacent surface <br />mining activity in Eckman Park. Partial backfilling and grading was done to help seal the portal area from <br />groundwater inflow. The remaining backfilling and grading will occur at [he completion of mining activity at <br />the Foidel Creek mine. No specific approvals are granted under this section. <br />Xl. Revegetation <br />The Division has previously approved the use of introduced species in the reclamation seed mix. <br />Introduced species are included in the pastureland and rangeland seed mixes. The applicant has <br />submitted information which shows that the introduced species are desirable and necessary to achieve the <br />approved post-mining land use, and are not poisonous or noxious, (4.15.2). <br />Methods to measure herbaceous cover and production, species diversity, and woody plant density are <br />discussed beginning on pages 2.04-52 and 2.05-I l5 of Vol. I for all but the Fish Creek Tipple area. <br />These techniques include: <br />a) ten-meter transects using a ten point optical frame every one meter for a total of 100 "hits" to <br />evaluate vegetative cover; <br />C:\JHB\C820561PR05\PROS FINDINGS 62800.doc <br />23 <br />
