Mining operations during previous permit terms have utilized long wall extraction and room and <br /> pillar techniques to extract coal from the "D" Seam. "D" Seam mining within the permit area <br /> was completed in 1999, with operations shifting to the underlying"B" Seam, beginning with <br /> development mining in 1998/1999 and the imitation of longwall mining in early 2000. Mining <br /> operations and schedules were substantially altered by a mine fire in longwall panel 9 in January <br /> 1996. The entire "D" Seam longwall mining district in the northern portion of the permit area <br /> was eventually sealed off and the longwall equipment not recovered. <br /> The original 1981 permit has been renewed seven times. The Deserado Mine permit was last <br /> renewed in May 2019. The current permit term is from May 29, 2019 to May 29, 2024. <br /> The majority of the Deserado Mine permit boundary lies within Rio Blanco County. With the <br /> final approval of PR-8, a portion of the Deserado Mine permit boundary lies within Moffat <br /> County. <br /> The general area of the mine is characterized by gently rolling to moderately steep landforms. <br /> The mine is located in the White River Basin, which is the eastern portion of the larger Uinta <br /> Basin. The permit area is located in portions of Sections 1, 2, 3, 4, 10, 11, and 12, Township 2 <br /> North, Range 101 West and all or portions of Sections 17 through 23, and 25 through 36, <br /> Township 3 North, Range 101 West of the 6th Principal Meridian. <br /> The post-mining land uses are grazing for livestock and wildlife at the mine site. <br /> Permit(C-1981-018) <br /> - Division issues Permit C-1981-018 July 7, 1981 <br /> - Permit Renewal No. 1 July 27, 1989 <br /> - Permit Renewal No. 2 July 27, 1994 <br /> - Permit Renewal No. 3 July 28, 1999 <br /> - Permit Renewal No. 4 January 4, 2005 <br /> - Permit Renewal No. 5 July 27, 2009 <br /> - Permit Renewal No. 6 October 21, 2014 <br /> - Permit Renewal No. 7 May 29, 2019 <br /> This Midterm Review is required to be completed by November 29, 2022. <br /> SECTION II—REVISIONS TO THE PERMIT <br /> The following is a summary of the revisions to the permit since the RN-7 Findings Document <br /> dated May 29, 2019. <br /> Revision No. Approval Date Nature of Revision Bond <br /> MR-175 06/03/2019 Belt press addition coal mining and +$13,691.00 <br /> reclamation <br /> TR-72 10/10/2019 Establishment of an additional +$644,078.00 <br /> refuse disposal area A and <br /> Deserado Mine -3- 12/21/2022 <br />
