_.. ., <br />-a- <br />results from each surface water sample (stream and NPDES) taken <br />during the quarter. The applicant should, therefore, ammend <br />the monitoring plan to reflect quarterly, not annual, submittal <br />of surface water data. Ground water data should also be <br />submitted on a quarterly basis. Quarterly submittal of <br />monitoring data is consistant with reporting requirements <br />placed on mining permits since February of 1981. <br />The annual mine inflow study should also include a discussion <br />of the source of each inflow (i.e. from fault, fractured roof, <br />abandoned exploration drill hole, weeping roof, weeping coal <br />face, roof bolt holes, seal to mined out panel area, etc.). <br />The monitoring plan should Snclude the submittal of an annual <br />report of hydrologic impacts of mining. This report should <br />incude an analysis of all hydrologic data collected during <br />previous year. This analysis should Include a discussion: 1) <br />of water use in the mining operation, 2) of water discharged to <br />receiving streams (quality and quantity), 3) of mine inflows <br />(annual mine inflow study), 4) of impacts to alluvial and <br />bedrock ground water quantity (lowering of ground water <br />levels), 5) of depletions In stream flows, 6) of impacts to <br />alluvial and bedrock ground water quality, and 7) of impacts to <br />spring flows, The annual hydrologic report should include a <br />discussion of how any adverse hydrologic impacts were mitigated <br />during the year. The annual report should include an <br />assessment of potential impacts of mining on the hydrologic <br />balance which may be encountered in the upcoming year, and also <br />a discussion of those mitigative measure which the applicant <br />will undertake to minimize these impacts. <br />If you have any comments or questions, please feel free to <br />contact me. <br />/ep <br />cc: Ed Bischoff <br />James Pendleton <br />Jerry Zimpfer <br />Doc.
