and alternate water supply discussion on revised permit application pages 2.05-99 through 2.05- 125 and page 2.04-37. Additionally, based on information from the Division of Water Resources, the worst possible consequences for the Bruce Park main dam and saddle dam will not result in material damage or diminution of reasonably foreseeable use. No further revisions to the permit application text were needed for this issue. However, the Division requested that the contingency subsidence control plan for the Bruce Park Dams mentioned under Rule 2.05.6(6)(d)(i) and described in Section 2.05.6(6)(f) be retained. This was done in the June 25, 2008 submittal, which contained a complete subsidence section on revised permit application pages 2.05-99 through 2.05-125. Rule 2.05 5. Please update the Probable Hydrologic Consequences section 2.05.6(3) of the permit application to include a discussion of the hydrologic impacts of the operations proposed in PR-10. The Division has no further concerns. BRL responded that no PHC updates were needed. The Division agrees. 6. In order to assess the hydrologic impact ofproposed limited extraction beneath a portion of Hubbard Creek, the Division requests that BRL develop a mine water inflow monitoring program, per Rule 2.05.6(3)(b)(iv). The monitoring program would include a survey of locations and rates offlow of seeps in the limited extraction zone beneath Hubbard Creek. The appropriate permit text needs to be revised to describe this monitoring program, including the methodology, a seep location map, seep rate of flow measurements and the frequency of monitoring and reporting. The Division has no further concerns. In the December 28, 2006 submittal, BRL revised page 2.05-78 to include a semi-annual seep monitoring program, the results of which are to be submitted in the Annual Hydrology Report. However, the Division requested that the seep monitoring and reporting frequency be on a monthly basis until it is established that the development mining beneath Hubbard Creek is not affecting Hubbard Creek. BRL revised page 2.05-78 accordingly in the January 30, 2008 submittal. 7. In Section 2.05.6(6)(a) of the permit application, please add the prehistoric campsite designated as 5DT1326 to the inventory ofstructures within the permit and adjacent areas. The Division has no further concerns. Page 2.05-99 was revised in the submittal dated December 28, 2006. The statement was later moved to revised page 2.05-100 in the June 25, 2008 submittal. 8. Under Rule 2.05.6(6) (a), please add depictions and annotations of the Terror Creek Ditch and the Deer Trail Ditch to Map 9, as they no longer appear to be presented on this map. The Division has no further concerns. BRL pointed out that the ditch depictions are already on the approved Map 23, Water Rights Location. 9. Although mentioned in Section 2.05.6(6)(a)(ii)(A) in the permit application, please add brief descriptions for the Hughes Cabins, the Terror Ditch and for those applicable portions of the 4
