Section - 2.04.7 !/ <br />Stored Mine Water - Information on the quality and characteristics of stored mine water is based on 1? <br />• monitoring, sampling, and analysis for both mine inflows, as discussed above (Wells B-6 and H-10 in <br />the B Coal Seam), and mme discharge from site SP-8 (Oliver Mine) in the D Seam. Based on <br />available analysis information and as shown by Figures 2.04.7-F7B, B Coal Seam Trlinear Diagram <br />and 2.04.7-177C, D Coal Seam Trilinear Diagram, the stored mine water is dominantly a sodium- <br />bicarbonate chemical type. <br />• <br /> <br />#.'
