9. The surface t/ater monitoring plan is addressed in Section 2.09.7(2) <br />Item 1 of ttus letter. , <br />5. Review of the proposed groundwater monitoring plan is found in Attachment C. <br />In order to shore compliance with 4.05.16 regarding diversion of water <br />into abandoned underground mine workings, the operator must demonstrate: <br />1. water quality is improved; <br />2, discharges meet effluent limitations; <br />3. ultimately the discharges will be treated by an existing treatment <br />facility; and <br />4. water ultimately discharged from these underground working meets <br />with both water quality standards and effluent limitations. <br />In order to assess the impacts of diversion of mine drainage into <br />abandoned underground workings, Empire Energy should be running chemical <br />analyses of water quality of the mine discharges before entering the old <br />working and the water quality of the water pumped out of the old r/orkings. <br />Also, Empire Energy should provide maps of the underground workings into <br />which water is being discharged; roof, floor interburden and coal analyses <br />of the old mine; a description of the coals electing, fracturing and <br />faulting and; the characteristics of first aquifer above and below the <br />coal seam itself. <br />S. The applicant does not include a specific discussion of the probable <br />hydrologic consequences of the mining activities under Rule 2.05.6(3)(b) <br />(iv). Based upon the results of the groundwater monitoring, surface water <br />monitoring and the data and analysis which should be provided under <br />Rule 2.09, the applicant should evaluate the possible effects to the <br />surface and ground water systems during and after the operation. <br />The discussion should separately consider surface water quantity and <br />quality, and ground water quality and quantity. Effects should be identified <br />as short-term (during mining and reclamation) or long-term (continuing <br />after reclamation). If no effect is anticipated, the applicant should <br />make that statement and provide sufficient analysis to support the statement. <br />If an effect is considered not be significant, the effect should be <br />identified and the reasons for its insignificance discussed. In order <br />to assist the Di. vision in making the written findings required by the <br />Act, the assessment should be as quantitative as possible. <br />2.05.6(6) Subsidence Survey, Subsidence Monitoring and Subsidence <br />Control Plan <br />Review of Empire's subsidence control plan is found in Attachment D. <br />-12- <br />
