Electrical Power Supply <br />Electrical power for the mine site is furnished by the Public Service Company of Colorado (PSC) <br />via a 115 -DV line from the Hudson Substation (near Hudson, Colorado) to a location at the <br />section corner between Sections 35 and 36. From there, PSC distributes power at 13,800 volts to <br />the former site of the dragline substation along the north -south line between Sections 25 and 26, <br />and east to the main access road, and then north to the facilities area. In addition, electrical power <br />from this line is supplied to two Snyder Oil Company natural gas compressor stations and a <br />Cellar One Communications Facility located to the east of the main access road which leads to <br />the CEC site. <br />Blasting Use and Potential <br />All remaining inventories of explosives remaining on site in 1995 were used to reclaim the Coal <br />Handling Facility during that year. With these supplies exhausted and no additional requirements <br />for an explosives inventory anticipated by CEC, a decision by CEC was made to let all <br />remaining ordnance licenses expire, and to request from the DMG's Mine Safety group (by letter <br />dated January 4, 1996) a final close-out inspection of the explosives storage facilities. If <br />necessary, any future explosives use on site would be performed by a licensed blasting contractor <br />selected by CEC. <br />Site Reclamation <br />Since mining is no longer taking place, site reclamation will be completed for the filled ash areas <br />in A- and B -Pits by placing a minimum of six (6) feet of overburden soils and two (2) feet of <br />topsand followed by the approved DMG revegetation program. Also, as facilities and overburden <br />stockpiles are removed, these areas will be reclaimed by backfilling them with the required <br />quantities of topsand, then revegetating the areas in accordance with the approved DMG <br />revegetation program. <br />A waste management plan exemption was granted in 1987 by the Board of County <br />Commissioners of Weld County contingent upon CEC burying its own non -coal wastes above <br />the ground water table and four (4) feet below the Approximate Original Contour (AOC) as <br />required by DMG Rule 4.11.4, "Disposal of Non -coal Wastes." CEC previously had been cited <br />twice for violations of having scrap oil and grease drums located on site, and in some cases <br />leaking, that reportedly had not been managed in a proper manner. In accordance with a Minor <br />Revision, MR #14 (dated April 4, 1990), CEC has established a protocol to no longer provide for <br />any outside storage of drums. Since almost all oil and grease is now delivered in bulk quantities <br />and recycled by outside vendors, there no longer occurs any storage of oil and grease drums on <br />the ground at the CEC property. <br />104 06/16 <br />
