12 July 2000 AGE-NC Project No. 96-0232 Page 2 of 2 point of discharge into the canal would be located in an area near the southeast intersection of Thomton Road and De Broggi Road. AGE would anticipate a continuous discharge of pre-treated ground water from Flag City Chevron to Canal No.DPC-79 at a flow rate of approximately 15 gallons per minute,or approximately 21,600 gallons per day. Based on modeling calculations of the Flag City Chevron subsurface impacted ground water plume, AGE estimates that discharge into Canal No. DPC-79 would be desired for approximately two years. Sampling ports would be installed to monitor influent and effluent of the "pump and treat"remediation system;receiving water monitoring stations(R-1 and R-2) would be set up 50 feet upstream and 50 feet downstream from the point of discharge to monitor effluent and the general water conditions of the canal. Prior to any discharge, an effluent monitoring and sampling program would be initiated at the Flag City Chevron site in a format acceptable to the DWR, RWQCB and the U.S. Fish and Game. Upon completion of the"pump and treat"remediation system at the Flag City Chevron site, the six- inch diameter discharge pipe from the Flag City Chevron site to DWR Canal No. DPC-79 would be removed from the subsurface, and all encroached areas returned to there original conditions.
