-12- <br /> FACT SHEET ORDER NO. 5-00-031 <br /> • <br /> ATTACHMENT C <br /> CITY OF LODI <br /> WHITE SLOUGH WATER POLLUTION CONTROL PLANT <br /> SAN JOAQUIN COUNTY <br /> for various.constituents regulated by the California Toxics Rule. The minimum detection limit <br /> proposed for lindane is 0.02 µg/1. The detection level was based on a survey of laboratories <br /> throughout the State to determine what levels could be reliably achieved by at least 20% of the labs. <br /> This Order requires the Discharger to monitor for all 303(d) listed pesticides including diazinon and <br /> -chlorpyrifos, as outlined in the monitoring and reporting program. The Discharger will be required <br /> by the Order to determine whether the level of diazinon and chlorpyrifos in the discharge cause or <br /> contribute to an in-stream excursion abovemater quality objectives, and allows the Board to reopen <br /> this Order and include effluent limitations for these specific pesticides which are not addressed by <br /> the Basin Plan. <br /> k) Monitoring of Constituents in Receiving Waters <br /> There are presently four receiving water sample stations (R-1 through R-4) used to monitor water <br /> quality in the receiving waters. A fifth monitoring station (R-5)has been added for this Order. The <br /> frequencies of sampling and required analyses have been modified from the previous requirements <br /> and are summarized in Monitoring and Reporting No. 5-00-031. These modifications reflect the <br /> need to better understand receiving water quality and its assimilative capacity for discharge of <br /> treated wastewater. Priority pollutant monitoring will be required at receiving water stations <br /> R-1 and R-2 collected with a quarterly frequency. Priority pollutant monitoring will be limited to <br /> Stations R-1 and R-2 since both locations represent the direct path of the effluent stream and will <br /> aid in our understanding of the potential for the receiving water to mix and dilute effluent priority <br /> pollutants. Daily DO monitoring at R-1 will be required since the DO conditions in Dredger Cut <br /> (5 mg/1 or greater) is a limiting factor for effluent discharge. <br /> 1) Reclamation _ <br /> The California Department of Health Services has established statewide reclamation criteria in Title <br /> 22, California Code of Regulations, Section 60301, et seq. (hereafter Title 22) for the use of <br /> reclaimed water and has developed guidelines for specific uses. The Board has consulted with the <br /> Department of Health Services, San Joaquin County Mosquito Abatement District and considered <br /> their recommendations regarding public health aspects for use of reclaimed water. This Order <br /> contains Specifications that require compliance with the guidelines developed in conformance with <br /> Title 22. <br /> A few industrial users subject to metal finishing pretreatment standards discharge process <br /> wastewaters to the industrial wastewater collection system, for direct discharge to the land disposal <br /> areas at the treatment plant. Metal finishing process wastewaters are generally "hazardous wastes" <br /> under the federal Resource Conservation and Recovery Act (RCRA) and are prohibited from <br /> discharge to land. However, metal finishing process wastewaters discharging to community <br /> sewerage systems are generally excluded from being regulated as a hazardous waste under <br /> 40 CFR § 261.4, because they are mixed with domestic sewage and other wastes that pass through a <br /> sewer system to a publicly-owned treatment works for treatment. The industrial waste collection <br /> system does not qualify as a community wastewater collection system under this exclusion, <br />
