MANAGEMENT <br />The DRMS' letter dated August 6, 2010 transmitted its adequacy review for the <br />referenced permit revision. This letter is sent to obtain clarification on item 11. <br />11. On the extreme western edge of the proposed new permit area, as shown on <br />Map 4-1, there is a portion of the Bowie No. 1 mine workings in section 15 that <br />lies immediately east of the proposed new permit boundary. In addition, it is <br />stated in the first paragraph on revised page 2 of Section 2.05 that secondary <br />recovery of pillars and barrier pillars took place. Please demonstrate that the <br />effects of subsidence from these mine workings do not lie outside of the <br />proposed new permit area. <br />BRL - The effects of subsidence do extend outside the permit boundary. The enclosed <br />Map 4-1 shows an optional permit boundary in the subject area for DRMS' <br />consideration. <br />Please call if you have any questions. <br />Enclosures: <br />Volume 4 Map 4-1 <br />Sincerely, <br />Jim Stover, P.E. <br />Consulting Engineer <br />cc: Wm. A. Bear, Jr. <br />
