J. J. Dudash - 11 - June 1, 2010 <br />BRL - Text was revised to explain Terror Creek Reservoir is formed by the Bruce Park Dam. <br />54. Please explain why the creek in Steven's Gulch is not included along with Hubbard Creek <br />and Terror Creek in the discussions on revised pages 2.05-136 and 2.05-142. <br />BRL - The creek in Stevens Gulch was added to the discussion on pages 2.05-136 & 142. <br />55. Discussion of the Bruce Park landslide begins at the top of page 2.05-137. While the <br />feature is analyzed in detail in the referenced Yeh study, the location of the landslide is not <br />apparent on Map 06 - Geological Hazards. Please modify Map 06 to indicate the location of <br />the Bruce Park landslide feature. <br />BRL - The Bruce Park landslide feature was noted on Map 06 as an unstable slope. <br />56. The third paragraph on page 2.05-137 describes the Hubbard Creek road. Please update <br />the text to incorporate the new Hubbard Creek Fansite. <br />BRL - The Operator's Hubbard Creek fansite was added to the inventory of structures on page <br />2.05-132. The third paragraph on page 2.05-138 directs the reader to section 2.05.3(3)(a) for a <br />description of the Operator's structures. <br />57. On revised page 2.05-137, BRL states that the Stevens Gulch road will be subsided and <br />that the road is protected where severe damage would occur by limited extraction. The <br />Division does not agree that Stevens Gulch road is protected by limited extraction areas <br />from activities as proposed under PR-12. Permit text on page 2.05-141 accurately describes <br />the subsidence consequences and mitigation for the Stevens Gulch road. Please correct <br />the permit text on page 2.05-137. <br />BRL - The permit text on page 2.05-137 was corrected. <br />58. The 3rd paragraph on page 2.05-140 refers to the potential impact to the Bruce Park <br />landslide of mine-induced seismic activity. Please consider modifying this paragraph to <br />include a reference to the Yeh 2006 study. <br />BRL- The Yeh 2006 study was referenced as suggested. <br />59. Please add permit text discussion at the bottom of page 2.05-142 regarding the subsidence <br />consequences and mitigation to any loss of surface water flow in Stevens Gulch. <br />BRL - The creek in Stevens gulch was added to the last paragraph on page 2.05-142. <br />60. The second paragraph on page 2.05-143 seems to be internally contradictory; "The <br />sandstone ledge that forms Dove Cave could collapse. However the sandstone ledge will <br />not be damaged since it is not within the area to be affected by mining." (Emphasis added) <br />Please verify that the text reads as it is intended to read, or change as appropriate. <br />BRL - The text was amended. <br />61. The 3rd paragraph on page 2.05-151 refers to a limited extraction zone that has been <br />established where the 1 West Mains cross under Terror Creek and the WAPA transmission <br />line. The following paragraph reiterates the WAPA zone. Maps 14-B and 27 do not appear
