the bench for the mine facilities and which has been destroyed, please provide an explanation <br />in the text concerning the destruction of the piezometer. <br />This issue is resolved. An appropriate note was added to page 115 of Section 2.05 in the <br />August 31, 2010 submittal. <br />10. On revised page 124 of Section 2.05, BRL is proposing to eliminate the requirement to install <br />nine new piezometers in the reclaimed backfill at the East Mine. The Division asks that BRL <br />remove this request from PR-4 so that the adequacy review of PR-4 is not complicated by an <br />important side issue. BRL can submit a separate technical revision to deal with this issue. <br />However, BRL should know that the Division considers the installation and monitoring of the <br />piezometers to be important due to the steep reclamation slopes. <br />This issue is resolved. In the August 31, 2010 submittal, BRL deleted revised page 124 of <br />Section 2.05. <br />11. On the extreme western edge of the proposed new permit area, as shown on Map 4-1, there is a <br />portion of the Bowie No. 1 mine workings in section 15 that lies immediately east of the <br />proposed new permit boundary. In addition, it is stated in the first paragraph on revised page 2 <br />of Section 2.05 that secondary recovery of pillars and barrier pillars took place. Please <br />demonstrate that the effects of subsidence from these mine workings do not lie outside of the <br />proposed new permit area. <br />This issue is resolved. In the August 31, 2010 submittal, Map 4-1 was revised to add additional <br />acreage on the west side of the permit area to take into account any possible subsidence in that <br />area. <br />12. The Division has not finished its review of the ground water aspects of PR-4. <br />This issue is resolved for PR-4. Since PR-4 only involves the transfer of a portion of the Bowie <br />No. 1 Mine permit area to the Bowie No. 2 Mine, and no new mining is proposed for the Bowie <br />No. 1 Mine, there are no ground water issues specific to PR-4. The ground water issues for the <br />transferred area are being handled in PR-12 for Bowie No. 2. If any ground water issues come <br />up for the remaining portion of the Bowie No. 1 Mine permit area, they will be dealt with <br />outside of PR-4. <br />Section 2.10 Maps and Plans <br />13. Please revise the Table of Contents pages for maps to indicate which maps show the approved <br />permit boundary. <br />This issue is resolved. BRL provided a six page map directory with appropriate permit <br />boundary notes in the August 31, 2010 submittal. <br />3
