Having said that, the water depletions associated with the proposed PR10 operations will be similar <br />to or (more probably) less than those for our recent and current operations, given projections of reduced <br />production levels. For the PR10 activities, we also anticipate that clewatering of non -tributary groundwater <br />stored in sealed and abandoned mine areas may result in supplemental contributions to normal strearnflows <br />in the area, rather than depletions. For any discharges associated with the mine clewatering activities, we are <br />Previous water depletion calculations (Foidel Creek Mine PHQ indicate "worst-case" depletions to the Fish <br />Creek drainage of approximately 11,000 gpd (approximately 1 2 cfs), or roughly 0.5 percent of the average <br />flow for the Fish Creek drainage, which is considered negligible. During active mining, we have implemented <br />a comprehensive water capture and recycling program for our underground and washplant operations, with <br />the result that both our water supply withdrawals from, and discharge to, area streams are minimal. The <br />limited amount of surface moisture retained on our coal product is offset by our limited mine inflows, which <br />are roughly equivalent. <br />Hopefully, this addresses your question.
