2.05.3 OPERATION PLAN <br />Coal is no longer being mined on the CEC property under this Permit; however, there are other <br />ongoing activities such as ash disposal, other non -coal non -hazardous waste disposal, and road <br />and facility maintenance which do not fit into the overall Reclamation Plan (2.05.5), that are <br />discussed herein. All existing features within the CEC Mine Permit boundary are shown on the <br />Existing Surface Features Map, presented in Appendix M-1 (updated annually in the AHR <br />Report). <br />Site Facilities in Use <br />The following CEC site facilities continue to be used: <br />♦ Sediment Pond 2, the Dugout Pond and the perimeter ditches (permanent features) <br />♦ A portion of the shop/office/warehouse building <br />♦ Laramie-Foxhills Formation water well #1-A (LFH #1) <br />♦ Electrical distribution lines <br />♦ Portable storage building (20'x 15'), currently located on west side of the shop/office <br />♦ Explosives magazine (see Maps M-1 & N-3) - used for records & equipment storage <br />♦ Diesel fuel storage tanks - (2) 12,700 gal./each and (1) 7,500 gal. - above ground, with <br />containment and dispensing system <br />♦ Portable equipment cover shed, skid -mount (formerly dragline bucket repair shed) <br />♦ Water storage tank - 8,000 gal., elevated <br />♦ Domestic Waste Treatment Facility (includes lift station, "plant" & evaporation pond) <br />The site facilities listed below are shown on the Existing Surface Features Map, see <br />Appendix M-1: <br />♦ Office, shop and warehouse, with additions <br />♦ Diversion/drainage/perimeter ditches, Dugout Pond and Sediment Pond 2 for surface <br />water runoff control (refer to TR -28, Drainage and Control Plan II) <br />♦ Domestic Waste Treatment Facility (see Appendix N-3) <br />♦ On site access roads, plans and profiles (see Appendix N-10) <br />♦ Electrical distribution system (see Appendices P-1 and P-2) <br />♦ Potable water system (see Appendix 0-1) <br />Disturbed lands in the facility areas have been mulched with manure and then seeded. Topsand <br />stockpiles A-1, A-3, B-1 and B-2 have been similarly treated for slope stability protection. Both <br />A and B Pits were reclaimed to elevations at a minimum of five (5) feet above the pre -mining <br />local groundwater table. A -Pit reclamation has been completed and B -Pit is currently being used <br />for ash (plus small amounts of mine waste rock) disposal. The estimate for 2016 fill is <br />approximately 25,151 cubic yards of ash plus daily cover soil for the year, CEC will no longer be <br />disposing of ash at this site after 2016. Thus, a present calculation of the "site -life" of the CEC <br />Keenesburg facility should be approximately 3 years. <br />102 06/16 <br />
