Box 2 <br /> Lockeford, California 95237-002 <br /> REVISED MONITORING AND REPORTING PROGRAM NOs. 90-312 AND 90-313, CITY OF <br /> LOCKEFORD WASTEWATER TREATMENT FACILITY, SAN JOAQUIN COUNTY <br /> Waste Discharge Requirements (WDRs) Order No. 90-312 and 90-313 were both adopted by <br /> the Regional Board on 2 November 1990. During a meeting with your consultants in January, <br /> staff learned that Lockeford CSD plans to request revised WDRs in the near future. As <br /> discussed at that meeting, the existing monitoring program is insufficient to characterize the <br /> facility wastewater and to determine if the wastewater discharge has resulted in groundwater <br /> quality degradation. Therefore, staff prepared a revised Monitoring and Reporting Program <br /> (MRP). The draft revised MRP was transmitted to you on 21 February 2006. We received the <br /> comments provided in the 31 March 2006 Comments to Draft Revised MRP, prepared by <br /> Ecologic Engineering and revised the draft MRP. <br /> Enclosed is the final Revised MRP; it replaces the MRPs from both orders listed above. <br /> Please note that this is effective immediately; therefore, your May 2006 wastewater sampling <br /> should conform to the requirements of the revised MRP. Please contact Tim O'Brien at <br /> (916) 464-4616 if you have any questions regarding the revised MRP or the WDR update <br /> process. <br /> MARK .
