Fourth Quarter 1994 Status Report 4 <br /> Golden Gram Company, Manteca Bean Facility, 229 Moffat Blvd, Manteca, CA December 22, 1994 <br /> • recording operational data and maintaining vacuum extraction blowers and vapor extraction <br /> system (VES) <br /> ■ checking and recording operational data for the air stripper and making adjustments as <br /> necessary <br /> ■ checking the condition of the catalytic water conditioner which minimizes fouling caused by <br /> the hardness of the water <br /> ■ performing a dally system operating parameters check via modem <br /> The soil vapor extraction and groundwater treatment systems ran continuously this quarter except <br /> during four occasions The following is a list of the clays that the remediation system was not <br /> operational <br /> 10/08/94-10/11/94 The catalytic oxidizer shut down for an unknown reason System <br /> interlocks functioned as designed, shutting down the groundwater <br /> extraction and treatment system,and the SVES The system was reset <br /> and was operating under normal conditions within two days after the <br /> system shutdown On October 11, piping to connect two additional <br /> vapor wells was installed and vapor extraction from all four vapor <br /> extraction wells began <br /> 10/26/94-10/27/94 Loose electrical connections within the catalytic oxidizer control panel <br /> caused the oxidizer to shut down System interlocks functioned as <br /> designed, shutting down the groundwater extraction and vapor <br /> extraction systems The electrical connections were tightened and the <br /> system was returned to normal operation <br /> 10/29/94-11/01/94 A burned wire from the main power relay to a system transformer <br /> caused the entire system to shut down The wire was replaced and <br /> the system was operational within one day of the system shutdown <br /> 11/02/94-11/04/94 Control components within the catalytic oxidizer failed causing the <br /> oxidizer to shutdown System interlocks functioned as designed The <br /> components were replaced with parts from the lead scrubber which <br /> was removed from the vapor stream during the site visit on <br /> November 4, 1994 The system was restarted and returned to normal <br /> operating parameters <br /> During this quarter of operation, there were no releases of untreated groundwater or untreated system <br /> effluent vapors System shutdowns were planned or occurred as a result of designed system safety <br /> interlocks, which shut down the remediation systems to preclude untreated releases <br /> 010211044 202 <br /> L1901GROUNDWATER <br /> TECHNOLOGY,INC <br />
