being placed in the Pond 1 basin. Prior to final backfilling and grading, the debris in the Pond 1 area <br />was compacted and then covered with at least four feet of nontoxic, noncombustible material (dirt). <br />Additional demolition debris consisting of concrete, coal fines from the stockpile area and debris <br />associated with the demolition of the office/shop/wazehouse building, was placed in, and in front of, <br />the portals. There was also some concrete that was broken and buried in place. This concrete <br />comprised the wing walls, foundation and apron (concrete slab making up a driveway and pazking azea) <br />of the office/shop/warehouse building. The wing walls, foundation and apron were broken in place to <br />allow water infiltration. Debris at the portal area was compacted and covered with at least four feet of <br />nontoxic, noncombustible material (dirt). Pond 1 and the portal area were approved as disposal areas <br />for demolition debris with Minor Revision 41 -approved on 18 January 2002 and Minor Revision 42 - <br />approved on 11 April 2002. <br />Ms. Paula Coulter expressed concems regarding the nature of the debris at the portal area in her 15 <br />November 2002 -etter. At the informal conference on 15 January 2003 she showed a video of the <br />portal area during reclamation. She had concems that tires, desks, cinder blocks, trash, black sludge, <br />scrap metal and concrete were being buried. In Ms. Coulter's video, the Division did observe one fire <br />on the edge of the fill material and other demolition related debris. Based on a call after the informal <br />conference to the Hazardous Materials and Waste Management Division (HMWMD) of CDPHE, the <br />Division determined that burying tires that were related to the mining activities is acceptable. Disposal <br />of solid waste generated by a mining operation within the permit boundary is in accordance with the <br />Solid Waste Disposal Facilities Act (Section 30-20-102(4)). <br />The Division finds that the demolition debris disposal plan is in compliance with Rule 4.11.4 and the <br />Solid Waste Disposal Facilities Act (Section 30-20-102(4)). <br />Three structures have been approved as permanent facilities at the request of the landowners. These <br />facilities are: <br />The truck tunnel (approved as a permanent structure with the approval of Minor <br />Revision 41 -approved on 18 January 2002) <br />Southfield Mine Permit No. C-1981-014 <br />SL-2 Findings 13 25 April 2003 <br />
