Box 808, L-293 DEPARTMENT <br /> Livermore, CA 94551-0808 <br /> WASTE DISCHARGE REQUIREMENTS NO. R5-2008-0148 FOR DOMESTIC AND <br /> EQUIPMENT WASTEWATER TO SEWAGE PONDS AND PERCOLATION PITS, <br /> LAWRENCE LIVERMORE NATIONAL LABORATORY SITE 300, SAN JOAQUIN COUNTY <br /> The Central Valley Regional Water Quality Control Board (Central Valley Water Board) <br /> adopted Waste Discharge Requirements (WDR) No. R5-2008-0148 for discharges of <br /> domestic and equipment wastewater to sewage ponds and percolation pits, and rescinded <br /> WDR No. 96-248 on 11 September 2008. As a result of our oversight, WDR No. <br /> R5-2008-0148 was adopted with the Standard Provisions from the California Code of <br /> Regulations (CCR) Title 27, instead of the 1 March 1991 Standard Provisions from CCR <br /> Chapter 15. A revision of WDR R5-2008-0148 to correct the Standard Provisions is not <br /> possible at this time. <br /> We understand that Lawrence Livermore National Laboratory (LLNL) is concerned with <br /> maintaining compliance with that part of the Central Valley Water Board Order. Therefore, by <br /> this letter we wish to assure you that staff will not recommend enforcement of any of the <br /> monitoring requirements in the Title 27 Standard Provisions in R5-2008-0148 that do not apply <br /> to LLNL's facility. Until such time as a revised Order is adopted, Central Valley Water Board <br /> staff will evaluate LLNL's compliance with the Chapter 15, 1 March1991 Standard Provisions, <br /> enclosed. <br /> If you have any que tions, you may contact Kathryn Dominic at (916) 464-1588. <br /> Antonia J.Vorster <br /> Site and Groundwater Cleanup Program Manager <br /> Enclosure <br /> cc list on next page <br /> California Environmental Protection Agency <br /> C11$Recycled Paper <br />
