Susan Mowry <br />Tom Schreiner <br />Pege 3 <br />Samples of discharge from Lower Refuse Pond (MB-6) that was <br />dewatered on 4-14-86 were as follows: <br />OUTFACE 010 <br />pH 8.44 su <br />Conductivity 1294 umhos/cm <br />Total Suspended Solids 12.0 mg/1 <br />Oil and Grease No visible sheen <br />Iron (total) 0.22 mg/1 <br />This sample is well within the requirements of NPDES permit <br />discharge limitations. <br />It is WECC's opinion that this was an operational problem, but not a <br />violation of permit requirements or standards. <br />No environmental damage can be attributed to the Lower-Refuse <br />Pond. <br />Bear No. 1 Area Sediment Pond (MB-5) <br />The Bear No. 1 Pond is located in an area where the water table is <br />controlled by the level of the North Fork of the Gunnison River and <br />other factors such as high springflow rates in the surrounding area, <br />etc. During periods of high water such as Spring runoff, the water <br />table essentially controls the level of the pond. This could be an <br />adverse situation, but in this case it is not. Samples taken during <br />recent spring runoff indicates that the baseflow tends to dilute any <br />runoff as a result if precipitation and therefore the water in the Bear <br />Pond is well within effluent discharge limitations. Recent <br />precipitation events on May 9, 10, 14, I5, and 16 which produced some <br />surface runoff did not have a degrading effect as indicated by the <br />following sample results: <br />May 9, 1986 Outfall 009 (Bear Pond) <br />pH 7.38 su <br />Conductivity 3250~umhos/cm <br />Iron (total) 1.48 mg/1 <br />Total Suspended Solids 16.0 mg/1 <br />Oil and Grease No visible sheen <br />
