TENTATIVE WASTE DISCHARGE REQUIREMENTS ORDER NO. -2- <br /> WASTE DISCHARGE REQUIREMENTS <br /> FOR CLOSURE,POST CLOSURE AND CORRECTIVE ACTION OF SURFACE <br /> IMPOUNDMENTS AT KRUGER FOODS, INC -SMS BRINERS VEGETABLE BRINING <br /> FACILITY SAN JOAQUIN COUNTY <br /> 6. The following are dates in which the Regional Board has asked the previous and current <br /> Dischargers in writing to comply with Subchapter 15 or Title 27 by closing or retrofitting <br /> their surface impoundments to the current regulatory standards. <br /> ■ 20 December 1988 <br /> • 10 February 1989 <br /> ■ 17 October 1989 <br /> 8 December 1989 <br /> ■ 24 May 1990 <br /> ■ 27 March 1992 (WDR Order No. 92-053) <br /> ■ 5 October 1995 <br /> ■ 1 May 2001 <br /> ■ 2 February 2002 <br /> ■ 16 December 2003 <br /> No retrofit or closure of surface impoundments has occurred. The original flexible liners are <br /> in poor repair with numerous holes exposed to the ground surface. Their condition does not <br /> comply with the prescriptive standards for Class R surface impoundments presented in Title <br /> 27 Table 4.1. This order is requiring the Discharger to "clean close"their impoundments per <br /> the requirements of Section 21400 of Title 27. <br /> 7. In December 1990, the Discharger completed installation of their Class I deep injection well <br /> (Souza#1) for the disposal of brine waste. The injection well is screened within a sand <br /> interval from—1720 feet msl to—2050 feet msl,which is beneath the Great Valley Sequence <br /> marine unconformity. The injection of brine waste into the subsurface is permitted by U.S. <br /> Environmental Protection Agency under UIC Permit Number CA 192000001. <br /> 8. The waste stream generated from the facility consists of a pickling solution of salt(sodium <br /> chloride) combined with potable water. Prior to installation of the injection well, <br /> approximately 7,500 gallons per day(gpd) of process wastewater were discharged to the <br /> surface impoundments resulting in approximately two million gallons of wastewater per year. <br /> The last known discharge of wastewater to the impoundments occurred on 18 November <br /> 2003. <br /> WASTEWATER CLASSIFICATION <br /> 9. The wastewater discharged into the surface impoundments prior to injection includes three <br /> components. The first component is process water, which incorporates waste brine,wash <br /> water, and brine tank rinse water. The second component is storm water run off, which <br /> incorporates runoff from the brining pads and from facility roadways. The third is extracted <br /> groundwater from MW-1 as part of their corrective action program. <br /> 10. `Designated waste' is defined in California Water Code, §13173, as a nonhazardous waste <br /> which consists of, or contains pollutants which,under ambient environmental conditions at <br /> the waste management unit, could be released at concentrations in excess of applicable water <br /> quality standards, or which could cause degradation of waters of the state.
