Permit Revision Adequacy Comment Response November 30, 2004 Page 6 of 24 ~7. On page 2.04-55, please discuss the presence or absence of groundwater seeps at Bowie sandstone outcrops. . MCC Response: MCC added discussion of the up-dip outcrop. 28. The discussion beginning on page 2.04-55 refers extensively to the Cumulative Hydrologic Impacts Analysis (CHIA). Those references are not appropriate in the context of the permit application. The data and observations on geology, hydrogeology, stratigraphy and structure are all secondary, derived from primary sources including the permit applications from the North Fork mines and others. This discussion should reference primary sources. References to conclusions drawn or calculations made in the CHIA by the Division is appropriate, but not the listing of data. MCC Response: MCC has made some comparisons to the CHIA data in Table 57 and 2.06. 29. On page 2.04-56, in the first paragraph, MCC seems to be saying that the transmissivity values derived from aquifer tests in the B-seam were so low that meaningful conclusions could not be drawn. Is that the case? Please reference the data used and add a concluding statement to the text. MCC Response: MCC has referenced the data and added a statement to the text. 30. On page 2.04-56, in the section "Upper Coal Member" the discussion on sandstone channels, are there any relevant observations where these formations crop out? If so, please discuss. MCC Response: MCC added discussion about the up-dip outcrop and proximity to the proposed m mine workings. 31. On page 2.04-56, in the last line, is "Bowie shale" intentional or should it be "Bowie sandstone?" MCC Response: MCC made the change to Bowie Sandstone for consistency. 32. Table 4 on page 2.04-57 should be amended to include the data from the wells in the E-seam and the alluvium of the Dry Fork of Minnesota Creek. MCC Response: MCC added the information from one-year of baseline on the E Seam and Upper and Lower Alluvial Wells. 33. Please include a discussion of the baseline groundwater data MCC is providing for the SOD permit revision, including a summary of data from the E-seam and aquifers above and below, as specified in Rule 2.04.7(1).
