Susan Burgmaier -4- July 10, 2014 BRL - The statement on page 2.04 -48 was revised. 13. The application materials submitted by BRL do not adequately address the baseline surface water information requirements of Rule 2.04.7(2). a. DBMS - 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 III 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. BRL - Baseline data collection is ongoing. b. DRMS - Data for springs, seeps and ponds also does not cover a twelve month period. Please update Exhibit 3 of Volume III 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. BRL - Baseline data collection is ongoing. DRMS - 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 III 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. BRL - There was a typo in the referenced section. The word ditches was changed to gulches on page 2.04 -54. Does DRMS really need documented baseline information for these ephemeral gulches. Revised page 2.04 -54 is enclosed. Rule 2.04.7(3) - Alternative Water Supply Information 14. DRMS - Revised page 2.04 -58 includes a discussion of the possible impacts to surface water features, and notes that Terror Creek is protected from the affects of subsidence by a limited extraction zone. No mention of the West Fork of Terror Creek, which will not be protected with limited extraction, is made. In accordance with Rule 2.04.7(3), please provide a discussion of the potential impacts from the effects of subsidence on the West Fork of Terror Creek.
