Panella trucking on Fremont and Cardinal, and spotted a 12" cement outfall pipe <br />discharging at an estimated 100-200 cfs. I got in my vehicle and drove to the outfall <br />where both Lori and I took water samples and samples of the solid deposit from the <br />cement pipe and nearby vegetation. At the same time I used the Hydrolab suveyor 4 <br />multimeter to take readings of water temperature, dissolved oxygen, electrical <br />conductivity and pH. The pH of the effluent was 8.96, the temperature was 20.99-C <br />and the Specific Conductivity was 1241.0. At 14:22 I checked in with my superior Bill <br />Jennings and updated him on the incident. Lori contacted EHD and Raymond J. Von <br />Flue arrived. EHD contacted the city to try and track the discharge. City referred to <br />County Channel Maintenance. Another DFG Warden arrived and then Lance Womble, <br />Steve Winkler and another individual (who's name I do not recall) from San Joaquin <br />County Channel Maintenance. Lori went upstream to collect another sample, which I <br />tested with the hydrolab and found the following readings: temperature 29.2°C, Specific <br />conductivity 230.7, and pH 8.01. These readings suggested that the cause of the fish kill <br />might be the effluent coming from the outfall The unnamed individual remembered <br />something about a permitted pipe discharge coming from the Marley Cooling Towers <br />site. Lori Oldfather and county staff went to Marley Co. to investigate. CIES Haz Mat <br />specialist Robert V. Lopez arrived and joined the investigation. At 16:59 the discharge <br />slowed dramatically and then stopped. It was apparent that the discharge had been <br />stopped by the source after county staff instructed them to shut it off. DFG and County <br />returned at approximately 17:25 and reported Marley Co. as the point source. The <br />employee on site (Dave Live) was reported to have informed DFG about a problem that <br />occurred Tuesday night, September 12, 2002. According to the Marley employee the <br />pump on the caustic tank froze in the "on" position and therefore stayed open all night <br />Tuesday September 12, allowing the effluent to discharge into the Calaveras diverting <br />canal. At approximately 18:30 I released my samples of effluent from the outfall to EHD <br />staff and then headed for DeltaKeeper. I arrived at DeltaKeeper at 19:00, placed my fish <br />samples in the freezer, gave a verbal report to Bill Jennings and turned over my field logs <br />and notebook for him to review. <br />Respectfully submitted, <br />Kari Morgan, DeltaKeeper Monitoring Coordinator <br />3536 Rainier Avenue <br />Stockton, CA 95204 <br />(209)464-4985 <br />
