J. J. Dudash -12- June 1, 2010 <br />to have been modified to illustrate the limited extraction zones described. Please revise <br />Maps 14-B and 27 to depict the limited extraction zones for the 1 West Mains. <br />BRL - Maps 14B and 27 were amended to show the limited extraction zone. <br />62. According to subsection 2.05.6(6)(c)(i) on page 2.05-144, the subsidence monitoring <br />program for the Bruce Park dam and Bruce Park landslide will be suspended. Text <br />regarding the monitoring program has also been struck through on page 2.05-149. <br />However, page 2.05-158 appears to retain language regarding monitoring of the Bruce Park <br />landslide. Please review the various monitoring plans for the Bruce Park Dam and Landslide <br />and verify that the permit text is internally consistent regarding the monitoring efforts <br />proposed. <br />BRL - Text regarding the monitoring program for Bruce Park dam and landslide were removed <br />from page 2.05-158. Additionally, the text regarding monitoring the tightly spaced subsidence <br />line installed on the edge of panel B-11 was deleted. <br />63. Because BRL is no longer proposing to mine within one mile of the Bruce Park Dam and <br />Terror Creek Reservoir, no material damage due to the Bruce Park landslide is anticipated. <br />Therefore, the Division requests that Section 2.05.6(6)(b)(iii) on revised page 2.05-143 be <br />revised to reflect this change. The Division also requests that a statement be made in this <br />same section that, should mining be proposed within one mile of the Brace Park Dam and <br />Terror Creek Reservoir, the subsidence control plan will be reactivated. The. same reference <br />should also be added to the appropriate sections of 2.05.6(6) which now discuss the <br />subsidence control plan, rather than deleting such text. If BRL wants to continue monitoring <br />of the Bruce Park Dam and the Terror Creek Reservoir on a voluntary basis, an appropriate <br />explanation should be placed into the text as well, such as on revised page 2.05-158. <br />BRL - The no material damage due to the Bruce Park landslide statement was added to page <br />2.05-143. The "should mining be proposed within one mile of the Brace Park Dam ...." <br />statement was added midway through the first paragraph on page 2.05-144. <br />Section 2.10 Maps and Plans <br />64. Please revise the currently approved Maps 11, 14 and 27-B to show that the new permit <br />boundary extends to the west. <br />BRL - The approved maps with new permit boundary are enclosed. Map 27-B was updated to <br />shown 2006, 2007, 2008 and 2009 subsidence features as show in the 2009 annual subsidence <br />report. Historical subsidence features can be found in prior subsidence reports. <br />Section 3.02.2 Determination of Bond Amount <br />65. Attached is the Division's reclamation cost estimate for PR-12. The estimate is comprised of <br />eight tasks (a summary sheet and tasks 251-257) and represents an increase in liability of <br />$45,039.00. This estimate included the transfer of three exploration holes (BRL-1-03-01, <br />BRL-1-08-01 and BRL-1-08-04), drill pads, light use roads, topsoil replacement and <br />reseeding from the Bowie No. 1 Mine permit into the Bowie No.2 Mine permit. The original <br />Bowie No. 1 Mine revisions were TR-4 1 and TR-49. The Division's estimate is more than <br />the one submitted by BRL because the Division updated the costs for the tasks from TR-41 <br />and TR-49 in the PR-12 estimate. Please inform the Division in writing whether or not this <br />estimate is acceptable to BRL.
