Groundwater availability in <br />the area may potentially be enhanced with the storage of water in the reclaimed pit. Colowyo currently <br />owns all water rights within Taylor Creek and owns over 20% of the appropriated amount (10.83 cfs of <br />the total 51.6 cfs available) of water available in Good Spring Creek. Thus, any potential diminishment <br />of flow will be compensated for by reduced use by Colowyo. There is sufficient capacity for Colowyo to <br />reduce their use of adjudicated water to compensate for potential diminishment of flow in the creek, <br />allowing downstream users full access to their water rights. <br />2.05.6 (4) Protection of Public Parks and Historic Places <br />No public parks are located within the permit or adjacent areas; therefore no public parks will be affected <br />by the mining operations. Likewise the mining operations will not affect any places listed or eligible for <br />listing in the National Register of Historic Places. <br />2.05.6 (5-6) Surface Mining near Underground Mining; Subsidence Control <br />No surface mining activities will be conducted within 500 feet of an underground mine. Therefore, there <br />is no subsidence control plan for operations. The Red Wing Mine, a historic underground mine, exists <br />north of the South Taylor pit and is shown on the existing Map 31. <br />2.06 PERMIT REQUIREMENTS - SPECIAL MINING CATEGORIES <br />2.06.1-3 Scope, Experimental Mining, and Mountain Top Removal <br />There will be no experimental mining practices at the South Taylor or Lower Wilson pits. <br />2.06.4 Steep Slope Mining <br />The steep slope mining procedures specified in Rule 2.06.4(2) will not be applicable to the South Taylor <br />Mining Area; however, Colowyo will be requesting a variance from approximate original contour for <br />steep slope mining in accordance with Rule 2.06.5 as outlined in the following section. <br />2.06.5 Variance from Approximate Original Contour Restoration Requirements <br />The South Taylor mining area will include non -mountaintop removal steep slope surface coal mining and <br />reclamation operations, where the operation is not to be reclaimed to achieve the approximate original <br />contour as required in Rules 4.14.1-4.14.6 and 4.27.3. Therefore, Colowyo is requesting a variance from <br />approximate original contour in the post -mining topography (PMT). This is due to the fact that steep <br />slopes will not remain steep slopes in the post -mining topography. However, the PMT will reflect the <br />pre -mining topography generally, with drainages and drainage divides remaining in their approximate <br />current locations. Post -mining topography is shown on Map 19B. The PMT was designed by Norwest <br />Corporation based on the Divisionrules for Operations on Steep Slopes as discussed in Section 4.27 of <br />this document. <br />South Taylor/Lower Wilson — Rule 2, Page 86 Revision Date: 4/7/17 <br />Revision No.: RN -07 <br />
