Annual Compliance Summary (Section V.C.1.f(1) and (3)) The District recognizes that the annual compliance summary table and the tabular data has previously been submitted electronically and are not required herein per Order No. R2- 2012 -0016, that became effective April 1, 2012. In this document, the District discusses treatment plant performance and compliance with the permit, presents yearly totals, averages, maximum and minimum values for influent, final effluent, sludge, ash, and receiving water quality parameters as a courtesy and considers the electronic submittals previously made as compliance with Sections V.C.1.f(1) and (3) of the Permit as the official Annual Report data. Comprehensive Discussion of Treatment Plant Performance and Compliance with the Permit (Section V.C.1.f(2)) The final effluent quality remained in compliance with all applicable NPDES standards for the year, making 2012 the fifteenth consecutive year that the District has accomplished this milestone. From July 18 through July 27, 2012, results for carbonaceous biochemical oxygen demand were reported from batches where the glucose glutamic acid recovery was greater than 72 percent, but below the method specified 84.6 percent. Final effluent and influent data for the time period remained within the Treatment Plant's historical range and well below permit discharge limits. On July 7, 2012, the District started its Outfall Inspection and Repair Project. The Regional Water Quality Control Board (RWQCB) was previously notified of the project on Dec 22, 2011 and the District received approval from the RWQCB on February 16, 2012. Monitoring requirements for the discharge during the bypass were conducted according to the approved letter and were submitted electronically.

O &M Manual The operations and maintenance (O &M) procedures are stored on the intranet on the Plant Information Management System (PIMS) and in binders located in the Plant Operations Control Room and in the Maintenance and Reliability Center. As systems change due to capital projects, new O &M binders are received from contractors and included in these libraries. Information included in both PIMS and the binders includes system overviews, procedures, alarms, troubleshooting, control strategies, and schematics. PIMS also contains videos pertaining to plant systems, equipment upgrades and modifications, additional system schematics, and plant operator training materials including video tests, practice exams, and certification information. In September 2011, the District began a comprehensive review of over 225 existing Standard Operating Procedures (SOPs). By June 2012, all of the existing SOPs had been converted into a standardized format, with consistent and clear terminology to improve readability for the operators. The District is still in the process of conducting a technical review of the reformatted SOPs by senior plant operators. PIMS has been updated with the reformatted SOPs, schematics have been relabeled so they are easier to locate, additional schematics and videos have been added, and the regulatory section has been overhauled with the most current reports, permits, and procedures. Contingency & Spill Prevention Plans The District's Contingency and Spill Prevention Plan was updated in August 2012 and included updates by recent capital improvements, facility changes, and current personnel. All edits have been thoroughly reviewed and approved by the District's Plant Operations Division Manager and Director of Plant Operations. The new edition of the Plan was distributed throughout the District to make recipients aware of the new edition; edits to the Plan were tracked on the Amendment Log for recipients to easily identify what has changed from the last edition. The next thorough review and evaluation of the District's Contingency and Spill Prevention Plan is scheduled for the summer of 2013.
