William A. Bear Page 3 of 9 May 19, 2014 West Fork of Terror Creek within the western permit area, as it will be with the Spruce Stomp expansion. 10. Revised page 2.04 -38 references the WWE study investigating potential impacts to the West Fork of Terror Creek. The WWE study was not included in the revision application materials, nor is it in the currently approved permit application package. Please include a proposal to incorporate the 2013 WWE study report as an appendix in the permit application package. 11. Please update the flow data for stream site (SW -05) on revised page 2.04 -48 to include the most recent monitoring data - the table submitted provides data through 2009, but the annual reports submitted by BRL report monitoring data for this site through 2013. 12. Revised page 2.04 -48 appears to have an error in the description of Stevens Gulch, which is perennial. Although this language is not proposed for revision, it should probably be clarified. Please revise the second paragraph of page 2.04 -48 to remove or revise the statement that flows in Stevens Gulch occur in response to snowmelt and precipitation events. 13. The application materials submitted by BRL do not adequately address the baseline surface water information requirements of Rule 2.04.7(2). a. For the West Fork of Terror Creek. The data collected at upstream site SW -12 is limited to three months of data, as opposed to the twelve consecutive months required to identify seasonal variations. No data was provided for site SW -1. Please update Exhibit 3 of Volume 111 to provide complete baseline data for the upstream and downstream locations on the West Fork of Terror Creek, sufficient to identify seasonal variations, in accordance with Rule 2.04.7(2)(b) and the Division's "Guidelines for the Collection of Baseline Water Quality and Overburden Geochemistry Data" document. b. Data for springs, seeps and ponds also does not cover a twelve month period. Please update Exhibit 3 of Volume 111 to provide complete baseline data for the springs, seeps, and ponds in the Spruce Stomp expansion area, sufficient to identify seasonal variations, in accordance with Rule 2.04.7(2)(b) and the Division's "Guidelines for the Collection of Baseline Water Quality and Overburden Geochemistry Data" document. c. Page 2.04 -54 identifies four unnamed ephemeral gulches and two ephemeral ditches tributary to Terror Creek, but no baseline data has been provided for these gulches and ditches. Please update Exhibit 3 of Volume 111 to provide complete baseline data for the springs, seeps, and ponds in the Spruce Stomp expansion area, sufficient to identify seasonal variations, in accordance with Rule 2.04.7(2)(b) and the Division's "Guidelines for the Collection of Baseline Water Quality and Overburden Geochemistry Data" document.
