<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 />12L, 13L, 14L, 15L, 16L, 17L, 18L. A portion of Fish Creek was undermined by longwall
<br />panels 12L, 13L, 14L, 15L, and associated gateroads. Routt County Road No. 27 is to be
<br />undermined by longwall panels 13L, 14L, 15L, 16L, and 17L. Coal production is not approved

<br />Permit Revision No.9 (PR -09) was submitted on August 7, 2012, and proposed to modify the

<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 withdrawal request was approved by
<br />the Division on June 12, 2013.

<br />12, 13, 14, 15, 16 and 17 in Township 5 North, Range 86 west. This Permit Revision includes
<br />mining of longwall panels 4RT, SRT, 6RT, 7RT, 8RT and 9RT and associated and gate and
<br />bleeder roads. A portion of Fish Creek and Foidel Creek was to be undermined. Routt County
<br />Road No. 33 was to be undermined
