Unt. data, graphing Trout Creek Sandstone are submitted herein as ich was apparently missing from the previous submitted herein as a revision page. .vision have previously agreed that a complete may need to be provided at approximately five e last "period of record" was included in the tic Report, with individual years being reported significant change is noted in collected TDS :h information will be of little value in ldentifying trend As per previous conversation, CEC does not feel that the TDS graphs are needed at this time. 6. Page 2.05.6-~4 has been corrected to refer to "The Theis equation for unst ady radial flow". The text starting on page 205.6-13 has been revised to state: "Since both the otentiometric gradients and the influence of gravity is from t e Twentymile Sandstone toward the target coal seam, no change i water quality would be expected as result of longwall mining o erations at the CEC Eagle #5 and #6 Mines." 7. Based upon r view of both USGS data and previously submitted data within the An ual Hydrologic Reports for 1990, 1991, and 1992 CEC would restate ur position that "no adverse impacts, due to CEC mining activity, as been observed between the two William's Fork River monitoring sites". Review of the data shows normal seasonal fluctuations fort a parameters noted in the Division Response, but does not indicate ny significant differences between the two sites that would warrant additional trend analysis at this time. As per previous conversa ion, CEC feels that the requested graphs of additional parame ers are not necessary at this time. 9. As per previ us conversation with DMG, Cyprus Empire has no baseline data on ater levels in the Okie Plaza well. 10. As has been p eviously discussed with the Division, until such time that signific nt changes are noted in data collected, graphs of dissolved solid iron and pH for all appropriate ground water monitoring wells, would be of little value. As per previous conversation, CEC does not feel that these graphs are needed at this time. 11. The text on page 2.04.7-2 states that ground water level declines in the Tr ut Creek Sandstone have dropped slightly due to continued use of t~e aquifer for mine water supply. The reference to declines due o drainage to No. 5 and No. 6 mine workings relates to the M'ddle Sandstone rather than the Trout Creek Sandstone. Thus, here is no contradiction with the statement on 2.05.6-12A of the ~HC which states that since water levels in the Trout Creek Sandst ne have recovered to earlier levels in both the Okie Plaza Well anQ the No. 5 Mine Wells while mine dewatering has
