Subsidence impacts on Foidel Creek, Middle Creek, and Fish Creek <br /> Subsidence of portions of Foidel Creek, Middle Creek, and Fish Creek will cause gradient <br /> changes in these streams. These gradient changes will result in ponding and channel <br /> incision controlled by the streams' relationship to orientation of longwall panels and <br /> gateroads. Subsidence cracks in the near surface also have the potential to disrupt the <br /> streamflow. Based on the presence of fine-grained alluvial material, any disruption of <br /> stream flows would be temporary. Site-specific experience from Foidel Creek resulted in a <br /> complete loss of streamflow for approximately 24 hours followed by recovery over the <br /> subsequent months. <br /> See section B, part III B of this document for more information concerning the surface and <br /> ground water monitoring plan. <br /> The Division has evaluated each of these impacts and finds that the operations proposed <br /> under the application have been designed to prevent damage to the hydrologic balance <br /> outside the proposed permit area(2.07.6(2)(c)). <br /> 4. The Division finds that the affected area is, subject to valid rights existing as of August 3, <br /> 1977, not within: <br /> a) An area designated unsuitable for surface coal mining operations (2.07.6(2)(d)(i)); <br /> b) An area under study for designation as unsuitable for surface coal mining operations <br /> (2.07.6(2)(d)(ii)); <br /> c) The boundaries of the National Park System, the National Wildlife Refuge System, the <br /> National System of Trails, the National Wilderness Preservation System, the Wild and <br /> Scenic Rivers System including rivers under study for designation, and National <br /> Recreation Areas (2.07.6(2)(d)(iii)(A)); <br /> d) Three hundred feet of any public building, school, church, community or institutional <br /> building, or public park(2.07.6(2)(d)(iii)(B)); <br /> e) One hundred feet of a cemetery (2.07.6(2)(d)(iii)(C)); <br /> f) The boundaries of any National Forest unless the required finding of compatibility has <br /> been made by the Secretary of the U.S. Department of Agriculture. (2.07.6(2)(d)(iii)(D)); <br /> g) One hundred feet of the outside right-of-way line of any public road except where mine <br /> access or haul roads join such line, and excepting any roads for which the necessary <br /> approvals have been received, notices published, public hearing opportunities provided, <br /> and written findings made (2.07.6(2)(d)(iv)); <br /> Permit Revision No. 2 (PR-02), approved undermining a portion of Routt County Road <br /> No. 27 in Section 33, TSN, R86W and Section 25, TSN, R87W. Routt County approved <br /> this undermining and subsidence of the road and the Division stipulated that the written <br /> Foidel Creek Mine 21 August 4,2023 <br />
