shown on Map King I-004. This well was monitored from 2000 to 2007, with no <br />significant changes to the water quality of the well. In 2009, this well was removed <br />from the ground water sampling program based on the lack of downstream effects to <br />the well and the termination of mining at the King I Mine. Down -gradient bedrock <br />monitoring of ground water will resume at least two years prior to submittal of a <br />bond release application. Adequacy of the resumed monitoring for satisfying the <br />requirement to monitor bedrock ground water will require DRMS approval of a <br />Technical Revision. <br />For a more detailed discussion of water monitoring please see Section 2.05.6. <br />All wells shown in Sections 28, 29, and 32, T35N R11W and Section 36, T35N <br />R12W lie within the Hay Gulch drainage, topographically below the coal seam <br />outcrop. There will be no Hydrologic effects on these wells or points of diversion. <br />There will be no impacts downstream of Pine Gulch due to subsidence related <br />depletion of flow. Subsidence could be caused by pillar extraction during retreat, <br />but pillars were not extracted. GCC Energy, LLC has submitted a mining plan <br />showing elongated pillars supporting all entries under the Pine Gulch drainage <br />system. These pillars will not be extracted on final retreat, thereby providing <br />perpetual stability for the Pine Gulch drainage and preventing potential damage to <br />the hydrologic balance outside the permit area. Map King I-012 shows the drainage <br />basin of Pine Gulch above those points proposed to be crossed by mine development <br />is included. The total area of this drainage is approximately 365.5 acres. <br />GCC Energy, LLC King I Mine <br />Section 2.04.7 <br />Page 7 July 11, 2017 (RN -07) <br />
