4. On proposed revised page 2.05- I01, a statement is made that the decreed water rights shown on Map 23 will not be affected by subsidence because they are outside the permit boundary. Please comment on whether or not subsidence could alter the ground water Clow and affect these water rights. 5. On proposed page 2.05-104, Section 2.05.6(6), please change the rule heading From (b)(ii) to (b)(iii) since that is the correct rule for a determination that material damage could occur. 6. On proposed revised page 2.05-105, in Section 2.05.6(6)(f)(ii)(A), please remove the word "longwall" from the first sentence since this revision does not address longwall mining. 7. Please provide proposed revised page 15 of Exhibit 15, Subsidence Prediction, since it was inadvertently left out of the submittal. 8. On proposed revised page l9 of Exhibit 15, Subsidence Prediction, the last sentence in Section 2.1, Land Use, lists Freemans Gulch and the stock ponds as those areas where disruption of surface water and ground water would be expected. However, in the approved permit application, on page 18 of Exhibit 15, Stephens Draw is also included as an area where disruption of surface water and ground water would be expected. Please justify this change or show in the permit application where this change has been justified. 9. On page 2.05-85 of the approved permit application, it is stated that there aze no springs in the permit or adjacent areas that are of a beneficial use. However, on proposed revised page 2.05-103, the sentence has been changed to say that most of the springs do not have a beneficial use. Please describe which springs have a beneficial use and what that use is. l0. Due to the existence of a fault west of the North Mains, BRL should address the potential for encountering substantial groundwater inflow to the mine workings. Please update the Probable Hydrologic Consequences (PHC) portion of the permit document to include a discussion of the potential for encountering large mine inflows when crossing the fault trace during development mining. Also provide a contingency plan for the safe handling and treatment (if necessary) of mine inflow water that may result from mining in the- vicinity of the fault trace. l 1. information presented in the TR-08 submittal indicates that localized perch water zones will be disrupted due to mining, and may result in mine inflows of short duration. As discussed above, much larger flows may also result from development mining across the fault trace located west of the North Mains. On page 38 of the Subsidence Handbook, BRL indicates that mine inflow monitoring will be conducted and reported in the "Annual Subsidence and Hydrology Report". The Division agrees that mine inflow monitoring should be conducted and reported. 2
