OJHKOIH ON THE WATER MEMORANDUM TO: Honorable Mayor and Members of the Common Council FROM: Stephan M. Brand, Public Works Utility Bureau Manager . DATE: June 17, 2014 RE: 2013 Wisconsin Department of Natural Resources (WDNR) Compliance Maintenance Annual Report for the Wastewater Treatment Plant BACKGROUND The City of Oshkosh is required by the WDNR as part of the Wisconsin Pollution Discharge Elimination System (WPDES) Permit to complete a Compliance Maintenance Annual Report. This report outlines the performance of the Wastewater Treatment Plant and sanitary sewer collection system for the previous year. This report needs to be formally approved by the Common Council and submitted to the WDNR by June 30, 2014. ANALYSIS The report is broken down into sections that address specific areas of performance for the wastewater system. Based on the responses in each section, a score is determined and a letter grade is given based on the score. This grade is used by the WDNR to determine the need for improvements to the wastewater treatment system. A letter grade of an A or B does not require any action be taken based on the information provided. The following is a brief summary of each section: Influent Flow and Loading: This looks at plant flow capacity and treatment ability based on the design of the facility. Our highest flow month for 2013 was May with a monthly average of 23.10 million gallons per day, which is 66 percent of the design flow of 35 million gallons per day. Our normal months are closer to 33 percent of design flow or an average of 11.5 million gallons per day. The treatment capacity is based on Biochemical Oxygen Demand (BOD) in pounds per day. Our highest influent loading monthly average was 14,657 pounds in the month of March. Our design loading is 33,360 pounds, which puts us at 44.0 percent of our design loading for the facility. Based on the available capacity of the facility, this section scored a letter grade A. Effluent Quality— BOD, TSS (Total Suspended Solids), Ammonia, and Phosphorus: Each of these sections look at the quality of our treatment individually for each of these parameters based on our permit requirements. There were no treatment issues for BOD, TSS, Phosphorus, or Ammonia. In September, we exceeded our Chlorine limit of no detect, as noted in the report. This occurred for one hour due to an instrument reagent calibration issue, which has been corrected. This did not affect our score for this category. BOD, TSS, Ammonia, and Phosphorus scored a letter grade A, �:\Engineering\Tracy Taylor\Memos to Mayor&Common Council\2014\2013 WDNR WWTP Comp Maint Annual Report_6-17-14.docx Page 1 of 2 Biosolids Management: Solids are generated from the treatment process, due to the growth of the microorganisms that are used for the treatment of wastewater. We have a separate process to treat this material as it is removed and turn it into a product that can be beneficially re-used as fertilizer on approved agricultural land. This section of the report looks at the treatment process and management of the biosolids in compliance with the permit requirements. All requirements were met and this section scored a letter grade A. Preventative Maintenance and Staffing: This section asks general questions about plant maintenance procedures, record keeping and staffing levels. There were no issues identified with either plant maintenance or staffing and this section scored a letter grade A. Operation Certification: The WDNR requires that facilities have certified operators on staff to operate and manage a wastewater treatment facility and that they attend approved conferences and training to obtain continuing education credits for certification renewal every three years. We have certified operators on staff who are certified at the appropriate levels for the wastewater treatment plant. This section scored a letter grade A. Financial Management: This section looks at the financial aspects of the utility and is done with the assistance of the Finance Department. In addition to rates, it looks at the funding in the Equipment Replacement Fund, which is required as a condition of the Clean Water Fund when financing projects through the Clean Water Fund Financial Assistance Program. We also have started including projects listed in the Capital Improvements Program in the Future Planning section to show future potential spending requirements. There were no issues identified and this section scored a letter grade A. Collection System: This section is completed using information provided by the Streets and Sanitation Division and Engineering Division based on the activities reported for sanitary sewer maintenance and construction in 2013. This section scored a letter grade A. Efforts are continuing to reduce clear water entry into the system. Flow monitoring and inspection of manholes for rehabilitation continues, along with televising to identify sanitary sewers in need of replacement. Sanitary sewer repairs and replacement projects are ongoing and are reflected in the Capital Improvements Program. Work plans for the Capacity Management Operations and Maintenance (CMOM) program and Sewer Evaluation and Capacity Assurance Plan (SECAP) are continuing to be updated and refined for the 2014 program year. The CMOM work plan is providing opportunities to further identify, define, and implement additional operation and maintenance activities related to the sanitary sewer system. The SECAP project first phase modeling is completed. It is being used to analyze the capacity of the sanitary sewer system under various dry and wet weather scenarios to determine where there may be capacity issues and to look at corrective action opportunities. The second phase will include collection of additional sanitary sewer information to be included in the model to further define and identify capacity issues and corrective action opportunities. RECOMMENDATIONS I recommend approval of the 2013 Compliance Maintenance Annual Report for submittal to the WDNR. Approved: Mark A.
