Dhaliwal Initiating Dept./Div.: Plant Operations/Operations ~5]) B. Dhaliwal r ~f::g tú- J. Kelly REVIEWED AND RECOMMENDED FOR BOARD ACTION: ISSUE: The Central Contra Costa Sanitary District's (CCCSD) Year 2000 National Pollutant Discharge Elimination System (NPDES), Collection System Overflow Monitoring Program, and the Recycled Water Quality and Distribution Reports have been prepared for submission to the California Regional Water Quality Control Board (RWQCB), San Francisco Bay Section. These annual reports are presented for Board of Directors' information and acceptance. RECOMMENDATION: Accept the Year 2000 National Pollutant Discharge Elimination System, Collection System Overflow Monitoring Program, and Recycled Water Quality and Distribution Reports. FINANCIAL IMPACTS: None AL TERNA TIVES/CONSIDERA TIONS: None BACKGROUND: Treatment Plant -- During the year 2000, the treatment plant received a total of 16,754 million gallons of wastewater, which equated to an average flow of 45.9 million gallons per day. This average flow is the same as for 1999. The treatment plant produced an effluent with an annual average biochemical oxygen demand (BOD) and total-suspended solids (TSS) concentrations of 6 and 9 mg/L each, respectively. These concentrations are markedly lower than our NPDES permit standards of 25 and 30 mg/L each. BOD and TSS removal efficiency for the treatment plant averaged 95 and 96 percent, respectively. Solids disposal during the year involved the incineration of dewatered sludge in the 1/16/01 S :\LAB\AnnuaIRpt\PosnPpr .00. wpd Page 1 of 3 POSITION PAPER Board Meeting Date: January 25, 2001 Subject: BOARD ACCEPTANCE OF THE YEAR 2000 NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM, COLLECTION SYSTEM OVERFLOW MONITORING PROGRAM, AND THE RECYCLED WATER QUALITY AND DISTRIBUTION REPORTS District's multiple-hearth furnaces. Approximately 5,127 tons of furnace ash was produced. The ash met regulatory requirements for final disposal throughout the year. More than 15,000 NPDES permit-required tests were completed to comply with the NPDES permit requirements. The treatment plant effluent met all (100 percent) of the permit requirements throughout the year. Effective January 1, 2000, the District started to submit its monthly self-monitoring report to the RWQCB electronically, as required. Because of the District's participation in the electronic data submittal program, the RWQCB has exempted the District from tabular and graphical reporting in the annual report. Consequently, this year's annual report does not contain any graphical presentations of data. All of the pertinent data is shown in the appropriate tables within the report. The District's NPDES permit also requires an annual update of the District's operation and maintenance procedures. A description of the updates is also included in the annual report. Collection System -- There were 34 reportable collection system overflows (overflows exceeding 100 gallons in volume), compared to 22 for the previous year. Only 3 of the 34 overflows exceeded 1,000 gallons in volume and were the subject of written reports submitted to the RWQCB. The causes of these three overflows were wet-weather surcharge, sewer pipe failure, and root blockage in the sewer pipe. The rest of the overflows were mainly due to root growth, grease deposition, and other blockages in the pipes. Further details on the overflows can be found in the attached reports. Recycled Water Oualitv and Distribution -- CCCSD distributed more than 175 million gallons of tertiary recycled water to various customers in the District's service area, compared to 89 MG for 1999. Recycled water quality met all applicable RWQCB reuse water-quality requirements and limitations. CCCSD plans to add another ten users in 2001. Submittal to the RWQCB -- Upon acceptance of these reports by the District Board of Directors, the reports will be submitted to the RWOCB. 1/16/01 5 :\LAB\AnnuaIRpt\PosnPpr .00. wpd Page 2 of 3 POSITION PAPER Board Meeting Date: January 25, 2001 Subject: BOARD ACCEPTANCE OF THE YEAR 2000 NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM, COLLECTION SYSTEM OVERFLOW MONITORING PROGRAM, AND THE RECYCLED WATER QUALITY AND DISTRIBUTION REPORTS RECOMMENDED BOARD ACTION: Accept the Year 2000 National Pollutant Discharge Elimination System, Collection System Overflow Monitoring Program, and Recycled Water Quality Distribution Reports. 1/16/01 S:\LAB\AnnuaIRpt\PosnPpr .00. wpd Page 3 of 3 RWQCB ANNUAL REPORT Purpose Summary of Calendar Year Performance Compiles Data for Twelve Monthly Reports In Essence "Our Report Card" to RWQCB RWQCB ANNUAL REPORT Contents Treatment Plant Waste Characteristics and Loading Waste Characteristics Into Plant Waste Characteristics In Treated Effluent Receiving Water Characteristics Suisun Bay Around Our Outfall Sewer System Overflows Recycled Water Report Usage Water Quality Annual Customer Inspections RWQCB ANNUAL REPORT Treatment Plant I Receiving Water Completed 15,000 Analytical Tests Approximately 11,000 Hours of Laboratory Work 100 Percent Compliance With NPDES Permit Requirements RWQCB ANNUAL REPORT Flow Information Total Flow Treated = 1999 16.7 Billion Gallons 2000 16.7 Billion Gallons Average Daily - 45.8 Million Gallons 45.9 Million Gallons Peak Hourly Flow = 168 Million Gallons/Day 200 Million Gallons/Day RWQCB ANNUAL REPORT Collection System Oveñlows Total Sewer Overflows 1999 22 2000 34 Overflows greater than 1,000 gallons 6 3 Causes: Pipe Failure Root Intrusion Wet Weather Surcharge Grease Debris RWQCB ANNUAL REPORT Recycled Water 1999 Recycled Water Customers 13 Million Gallons Recycled Water Delivered 93.4 Peak Month Usage 16.6 / (July) 100 Percent Compliance With Title 22 Requirements No Customer Complaints 2000 15 175.5 33.4 / (June) RWQCB ANNUAL REPORT Changes In Year 2000 Electronic Reporting Starting January, 2000 LIMS Implementation Complete New NPDES Permit With Additional Challenges More Stringent Requirements Fines For Violations (AB 709) RWQCB ANNUAL REPORT Acknowledgements Operations Staff Laboratory Plant Operators Maintenance Staff Buildings and Grounds Mechanical Maintenance Electrical & Instrumentation Shops Process Cantrall Maintenance Engineering Collection System Crews Engineering Staff Source Control Pollution Prevention Water Recycling Desig n/Construction Administrative Public Information Human Resources Pu rchasinglWarehouse Board of Directors RWQCB ANNUAL REPORT Recommend,atioo'....nH ...
