Also attending <br />this meeting were Jim Giottinnini, Director of Public Works, city of <br />Stockton; J.C. Isham, EMCON Associates (EMCON); Stephen Chen, city <br />of Stockton; and John Boss, EMCON. <br />1. Ed Padilla indicated that the California Integrated Waste <br />Management Board (CIWMB) was concerned about the <br />recirculation of landfill gas condensate into the landfill. He <br />indicated that Pacific Electric had reported that approxi- <br />mately 60 to 120 gallons per day of condensate were <br />reinjected into the landfill. According to Mr. Padilla, the <br />CIWMB wants to prohibit this recirculation, and has <br />indicated that this is a violation of the permit as part of its <br />last inspection. Mr. Padilla agreed to research what basis <br />was used for considering this to be an operating permit <br />violation. (Note: John Boss investigated this further and <br />found that the violation was for leachate control due to the <br />detection of ground -water contamination.) <br />The landfill gas extraction system operator received <br />approval from the Regional Water Quality Control Board <br />(RWQCB) for this activity.
