<br />subsided portions of Fish Creek and its associated alluvial valley floor in sections 16, 15, 10 and
<br />11.
<br />Permit Revision No. 6 (PR -06), was approved on May 21, 2004. Permit Revision No. 6
<br />provided for continued mining in the Northern Mining District in Sections 3, 4, 7, 8, 9, 10, 11,

<br />Permit Revision No. 7 (PR -07), was approved on January 2, 2007, and allowed for continued
<br />longwall and development mining in the Northern Mining District in sections 4, 5, 6, 7, and 8 of
<br />TSN, R86W, and development mining in the Western Mining District into portions of Section 17
<br />and 18, TSN, R86W, and Section 13 TSN, R87W.
<br />Permit Revision No. 8 (PR -08) was approved on October 30, 2009, and allowed for the
<br />expansion of mining in the Western Mining District with development and longwall mining in
<br />Sections 17, 18, 19, and 20 of TSN, R86W, and 13, 22, 23, 24, 25, 26, and 27 of TSN, R87W.
<br />This Permit Revision includes mining of longwall panels 12L, 13L, 14L, 15L, 16L, and 17L, and
<br />gateroads 12L, 13L, 14L, 15L, 16L, 17L, 18L. A portion of Fish Creek was approved to be
<br />undermined by longwall panels 12L, 13L, 14L, 15L, and associated gateroads. Routt County
<br />Road No. 27 was approved to be undermined by longwall panels 13L, 14L, 15L, 16L, and 17L.
<br />Coal production was not approved to increase beyond the previously approved 12,000,000 tons
<br />per year with the approval of PR8.
<br />Permit Revision No. 9 (PR -09) was submitted on August 7, 2012, and proposed to modify the
<br />approved Foidel Creek Mine plan for the Western Mining District (WMD). PR -9 proposed to
<br />add an additional longwall panel, the 11 -Left Panel, and to include an extension of the 12 -Left
<br />and 13 -Left Panels. The additional panel, and panel extensions to the west, would have required
<br />modification of the currently approved Foidel Creek Mine Permit Area boundary, adding
<br />approximately 560 acres to the Mine Permit Area. Due to potentially unstable mining conditions
<br />in the PR -09 area, TC requested to withdraw PR -09. The withdraw request was approved by the
<br />Division on June 12, 2013.
<br />Permit Revision No. 10 (PR -10) submitted on January 8, 2015 and Permit Revision No. 11 (PR -
<br />11), submitted on July 8, 2015, proposed to include development and longwall mining of the
<br />Wolf Creek Coal Seam Reserve. The Permit Revisions addressed mining of five of the initial
<br />panels (9RT, 8RT, 7RT, 6RT and 5RT). The Permit Revisions also included development of an
<br />internal ventilation and utility shaft in the Wolf Creek main entries. PR -10 was approved May 4,
<br />2016 and PR -11 was approved February 25, 2016.
