Susan Burgmaier -3- July 10, 2014 <br />BRL - Drill hole SS -9 was added to Map 8A. Maps 8,8A and revised pages 2.05 -122 & 123 <br />are enclosed. <br />Rule 2.04.7 - Hydrology Description <br />Rule 2.04.7(1) - Ground Water Information <br />The Division has not yet completed its review of the application materials addressing baseline <br />ground water information. Comments on ground water will be forwarded to BRL at a later <br />date. <br />Rule 2.04.7(2) - Surface Water Information <br />9. DMRS - Currently approved page 2.04 -12 indicates that the West Fork of Terror Creek <br />is north of the western permit area; the West Fork of Terror Creek will be within the <br />permit and affected areas with the PR -14 expansion. Please update page 2.04 -12 to <br />reflect the location of West Fork of Terror Creek within the western permit area, as it <br />will be with the Spruce Stomp expansion. <br />BRL - The location of the west Fork of Terror Creek was corrected on page 2.04 -12. <br />10. DRMS - Revised page 2.04 -38 references the WWE study investigating potential <br />impacts to the West Fork of Terror Creek. The WWE study was not included in the revision <br />application materials, nor is it in the currently approved permit application package. <br />Please include a proposal to incorporate the 2013 WWEstudy report as an appendix in <br />the permit application package. <br />BRL - The 2013 WWE Evaluation of Potential Subsidence Impacts of Longwall Mining in <br />the Spruce Stomp Lease Area to Aquatic Life and Water Supply will be incorporated <br />into the permit in new Volume IIIB, Tab 23. A reference to the report's location was <br />added to page 2.04 -38. The table of contents was revised to incorporate this new <br />Volume IIIB. <br />11. DRMS - Please update the flow data for stream site (SW -05) on revised page 2.04 -48 <br />to include the most recent monitoring data - the table submitted provides data through <br />2009, but the annual reports submitted by BRL report monitoring data for this site through <br />2013. <br />BRL - Data were updated for SW -05. Amended page 2.04 -48 is attached. <br />12. DRMS - Revised page 2.04 -48 appears to have an error in the description of Stevens <br />Gulch, which is perennial. Although this language is not proposed for revision, it should <br />probably be clarified. Please revise the second paragraph of page 2.04 -48 to remove or <br />revise the statement that flows in Stevens Gulch occur in response to snowmelt and <br />precipitation events. <br />
