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 six times. The Deserado Mine permit was last <br />renewed in October 2014. The current permit term is from July 27, 2014 to July 27, 2019. <br />Operational status was most recently reviewed and summarized by the Division in Permit <br />Revision No. 8 (PR -8), which received final approval on August 5, 2013. <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-1981-01 <br />- Division issues Permit C-1981-018 <br />- Permit Renewal No. 1 <br />- Permit Renewal No. 2 <br />- Permit Renewal No. 3 <br />- Permit Renewal No. 4 <br />- Permit Renewal No. 5 <br />- Permit Renewal No. 6 <br />This Midterm Review is required to be completed by January 27, 2017. <br />SECTION II — REVISIONS TO THE PERMIT <br />July 7, 1981 <br />July 27, 1989 <br />July 27, 1994 <br />July 28, 1999 <br />January 4, 2005 <br />July 27, 2009 <br />October 21, 2014 <br />The following is a summary of the revisions to the permit since the RN -6 Findings Document <br />dated August 13, 2014. <br />Revision No. Approval Date Nature of Revision <br />MR -160 08/13/2014 Nitrogen Plant #2 Facilities <br />MR -161 09/24/2014 Nitrogen Pipelines <br />me <br />+$7,968.46 <br />+$74,198.16 <br />Deserado Mine -3- 1/26/2017 <br />
