1- v California ReWonal Water Quality Control Board Central Valley Region Ter Tamminen Robert Schneider,Chair Terry Arnold Schwarzenegger Secretaryfor 3443 Routier Road,Suite A,Sacramento,California 95827-3003 Govemor Environmental (916)255-3000•Fax(916)255-3015 Protection http://www.swreb.ca.gov/mgcb5 23 April 2004 Jim McAnnelly, Facility Manager Super Store Industries 16888 McKinley Avenue Lathrop, CA 95330 REVIEW OF REPORT OF WASTE DISCHARGE,SUPER STORE IND USTRIES,SAN JOAQUIN COUNTY On 20 June 2003, you submitted a Report of Waste Discharge(RWD) for the discharge of ice making water onto land. The RWD was for coverage under the Regional Board's Resolution No. R5-2003-008, Waiver for Specific Types of Discharge Within the Central Valley Region(Waiver). Upon review of the RWD, staff determined that the RWD was not complete and in a letter, dated 25 June 2003, informed you that a filing fee and additional information must be submitted. You responded to that request on 8 July 2003. Since that time, staff has been in communication with your consultant about additional data required in order to ensure that the discharge would meet the particular conditions of the Waiver, specifically, that the total dissolved solids (TDS) concentration of the discharge would be less than that in the uppermost underlying groundwater. On 5 February 2004,DJH Engineering provided us with groundwater data indicating that the TDS concentrations in the discharge were less than the average TDS concentration in underlying groundwater. Although the discharge meets the specific requirements of the Waiver, after further consideration of the volume of waste that will be discharged(12,000 to 17,000 gallons per day) and method of discharge(flood irrigation),it is staff's determination that coverage under the Waiver is not appropriate and that the discharge would be more appropriately covered under State Board's Water Quality Order No. 2003-0003-DWQ, General Waste Discharge Requirements for Discharge to Land with a Low Threat to Water Ouality(General WDRs).jhe Waiver is more appropriate for one-time discharges,while this discharge will be long-term. In addition,because of the volume and method of the discharge, ongoing monitoring is warranted, and therefore better regulated under the General WDRs. The General WDRs may be found on the Internet at www.swrcb.ca.gov/resdec/wgorders/2003/wqolog.html. The information submitted to date will be used to enroll you under the General WDRs. However, we cannot enroll you until you supply evidence of compliance with the California Environmental Quality Act(CEQA). Has a CEQA document for this discharge been certified by a public entity?
