I 1 <br />' MINREC, INC. ANNUAL HYDROLOGIC REPORT PAGE 3 <br />measurements for the year were consistent with prior years data. <br />The conductivity measurements were also consistent with prior <br />t years. The pH measurements for the wells were similar to prior <br />years monitoring. <br />' MINE FLOWS <br />' Due to an unusually wet spring the water levels in both the No. 1 <br />Mine and No. 3 Mine increased. <br />' All of the water flowing into the No. 1 Mine is being allowed to <br />flow out of the mine into the treatment ponds. Measurements of the <br />water level in the mine are taken at two valves that penetrate a <br />' concrete bulkhead in the mine portal. One of the valves penetrates <br />the seal approximately 3 feet higher than the other. The water <br />level in the mine has been maintained below the upper valve and <br />t above the lower valve during the year. Therefore, the level of <br />water inside the mine has been stable during the year. <br />' The No. 3 Mine, (Outfall 007), has two separate sources of <br />discharge. One is from a point source (spring) within the Mine <br />' that is piped directly to the surface. This good quality point <br />source of water has been the source of the discharge from the No. <br />3 Mine, (Outfall 007), since the mine was sealed in 1986. The <br />' water level in the mine has fluctuated since that time but no water <br />has discharged directly from the mine in ten (10) years. During <br />the second quarter, the very wet spring weather evidently caused <br />' the mine to fill and begin discharging iron laden water. <br /> The discharge was first discovered on Monday, June 26, 1995 at <br />about 9:45 a.m. Approximately 67.5 gpm was flowing from the mine. <br />The discharge was inspected on Wednesday and Friday of the same <br />week and the flow was decreasing quite rapidly. <br />' In order to handle the non-compliance discharge, Minrec combined <br />' the discharge from the No. 3 Mine, (Outfall 007), with the <br />discharge from the No. 1 Mine, (Outfall 001), as provided for in <br />its discharge permit. A 4" diameter pipe has been installed to <br />convey the discharge from Outfall 007 to the long pond. The <br />discharges from the mines were combined effective August 11, 1995. <br /> <br /> <br />
