CO-0033685, 2ND QUARTER 1995 DISCHARGE <br />MONITORING REPORTS. <br />To Whom It May Concern: - <br />,Ic <br />(.- <br />Please find enclosed seven completed Dt1R forms addressing the Tst Quarter <br />of 1995 for NPDES Permit No. CO-0073685. <br />You will note that on May 12, 1995, Outfall 002A exceeded discharge <br />limitations. Between May 3rd and May 12th, the Bowie X1 Mine received <br />approximately 1.05 inches of rainfall and on Hay 12th, received and additional <br />1.1 inches of rain. This unusually heavy rainfall in combination with leaks <br />located in Pond X4's binwall and valve assembly, severely limited the retention <br />time necessary to meet discharge limits. It should be noted, as new owners and <br />operators, Bowie X1 Mine has never seen Pond A4 with as much water. Upon <br />discovering, Bowie Resources took action in correcting this problem. <br />When weather permitted, water in Pond ¢4 was pumped back up to Pond fJ so <br />as to allow repair work to begin on Pond X4. Repair work on pond consisted of <br />placing a bentonite mat along the bottom perimeter of the pond as well as along <br />the sides then additional material was placed over the mat and compacted. The <br />leaking valve assembly was then replaced with a new 12" valve and tested so to <br />assure a tight seal. It should be noted that the Bowie ,91 Mine continued to <br />receive heavy rainfall after the repair work, and no sighs of leaking were found. <br />In conjunction with repairing Pond !'4, sedimentation ponds located upstream were <br />also cleaned. By cleaning these ponds, additional storage space has been created <br />as well as a greater retention time. <br />Howie Resources Ltd. is currently exploring the possibility of rebuilding <br />several of these ponds so as to further minimize the potential of exceeding <br />discharge limits in the future. <br />Thirty day average values reported on the enclosed DHR's represent the <br />maximum thirty day average values generated for this quarter. <br />If you have any questions regarding this submittal please contact me at <br />(970)527-4135. <br />B/owie Resourc e/5~s Limited <br />'~~1~/~ Jar ~~~ ~7 <br />William A.
