<br /> <br />J.E. Stover & Associates -26- <br />Bowie No. 2 Mine <br />May 31, 1996 <br />analyses of the coal seams provided within Exhibit 6 of Volume <br />III show the Upper B-Seam to vary from 0.4$ to 0.01$ (average <br />0.145&) dry weight pyritic sulfur. This data also shows the <br />Upper D-Seam to vary from 0.05$ to 0.01$ (average 0.027$) dry <br />weight pyritic sulfur. The data included within Exhibit 6 <br />regarding occurrence of calcium shows minimal amounts of soluble <br />Calcium and Magnesium to be present in the roof and floor rock. <br />No Calcium or Magnesium data is provided for the two coal seams. <br />No anion analyses, such as carbonate, or acid/base potential <br />determinations are provided for any of the coal., floor or roof <br />materials. <br />77. BRL's conclusion that sufficient lime is present within the <br />coal to negate the formation of acid within these coal seams <br />is unsupported. BRL should expand upon its conclusion <br />regarding the acid forming potential of the upper B-seam and <br />upper D-seam Williams Fork coals. Failing this <br />demonstration, consideration would have to be given to the <br />disposal of potentially acid-forming coal mine waste within <br />the proposed coal refuse pile. <br />2.05.5 Post Mining Land Uses <br />No comment. <br />2.05.6 Mitigation of the Impacts of Mining operations <br />2.05.6(1) Air Pollution Control Plan <br />As with the CDPS permit, this question is being added to ensure <br />that the final approved air emission permit is included in the <br />permit application. <br />78. BRL should submit a final approved air emission permit in a <br />format which can easily be inserted into the permit <br />application prior to approval. <br />79. On page 2.05-64 of the permit application, speed limits of <br />20 to 30 mph are stated. The Division wishes to add that <br />there may be further limitations on speeds due to fugitive <br />dust potential. The fugitive dust air emissions permit will <br />state such limitations, if any. <br />2.05.6(2) Fish and Wildlife Plan <br />
