A& City of Oshkosh MEMORANDUM TO: Honorable Mayor and Members of the Common Council FROM: Stephan M. Brand, Public Works Utility Bureau Manager DATE: June 22, 2017 RE: Approve and Submit 2016 Wisconsin Department of Natural Resources (WDNR) Compliance Maintenance Annual Report/ Wastewater Treatment Plant BACKGROUND The City of Oshkosh is required by the WDNR as part of the Wisconsin Pollution Discharge Elimination System 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. The results reflect the dedication of the Wastewater Utility staff and their commitment to protecting the community's public health and water environment. This report needs to be formally approved by the Common Council for submittal to the WDNR by June 30, 2017. 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 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 section looks at plant flow capacity and treatment ability based on the design of the facility. Our highest flow month for 2016 was March with a monthly average flow of 19.02 million gallons per day, which is 54% of our design flow of 35 million gallons per day. Normal months are closer to 36% of design flow with an average of 12.7 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 16,061 pounds in the month of February. Our design loading is 33,360 pounds, which puts us at 48.1% of our design loading for the facility. This section has been updated to include questions on flow meter calibration, the Sewer Use Ordinance, Septage Receiving (Hauled Waste Delivered to the Plant), and the Pretreatment Program. No issues were identified in any of these areas. Based on these responses and the available capacity of the facility, this section scored a letter grade A. Effluent Quality — BOD, TSS (Total Suspended Solids) Ammonia and Phosphorus: These sections look at the quality of our treatment individually for each of these parameters based on our permit requirements. There is a regulatory limit for mercury and, as noted in the enclosed report, we exceeded our mercury limit on one (1) sample. We did subsequent testing and analysis on the potential cause for this one (1) exceedance, which is also explained in the enclosed report. All subsequent testing was within permit limits. The sections for BOD, TSS, Ammonia, and Phosphorus each scored a letter grade A. Biosolids Management: Solids are generated from the treatment process due to the growth of microorganisms that are used for the treatment of wastewater. There is a separate process used 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 1: \ Engineering \Tracy Taylor\ Memos to Mayor & Common Council \ 2017 \ 2017 WDNR W WTP CMAR_6-22-17.docx evaluates 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. Staffing and Preventative Maintenance: 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. Operator Certification and Education: The WDNR requires wastewater facilities have state -certified operators on staff to operate and manage the facilities to meet the requirements of the Wisconsin Pollutant Discharge Elimination System Permit. Certified operators are required to attend approved conferences and training to meet continuing education requirements for the certification renewal every three (3) years. We have certified operators on staff who are certified at the appropriate levels for the wastewater treatment facility. 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 have also started including projects listed in the Capital Improvements Program (CIP) in the Future Planning section to show future potential spending requirements. There were no issues identified and this section scored a letter grade A. Sanitary Sewer Collection Systems: This section is completed using information provided by the Streets Division and Engineering Division, based on the activities reported for sanitary sewer maintenance and construction in 2016. There was one (1) sanitary sewer overflow reported, due to a force main break that occurred just outside the Snell Road Lift Station. As noted in the enclosed report, it was fully contained and cleaned up. This force main and lift station were eliminated with the Snell West construction project, which installed a new gravity sewer and a new lift station to replace the existing Fountain Avenue Lift Station. Based on the activities reported, this section scored a letter grade A. Efforts continue to reduce clear water entry into the sanitary sewer system. Flow monitoring and inspection of manholes for rehabilitation continues, along with televising to identify sanitary sewers in need of replacement. Sanitary sewer repair and replacement projects are ongoing and reflected in the CIP. The Capacity Management Operations and Maintenance program has been fully implemented and continues to provide opportunities to update and refine operations and maintenance activities related to the sanitary sewer system. The System Evaluation and Capacity Assurance Plan has also been completed and includes a City-wide sanitary sewer model. This model continues to be used to analyze the capacity of the sanitary sewer system in specific areas under various dry and wet weather scenarios to determine where there may be capacity issues and to look at corrective action opportunities. It is also being used extensively in CIP planning and area planning studies for future sewer requirements. RECOMMENDATIONS I recommend approval of the 2016 Compliance Maintenance Annual Report for submittal to the WDNR.

The Mercury PMP program was developed and implemented in 2007. Plant Staff have been actively working with various sectors in implementing and maintaining BMP's for their facilities. Sewer cleaning records were reviewed at the time of the sampling and jetting was done near the WWTP and in the vicinity of some commercial facilities where legacy material may have been present. In order to verify if this could be a continuing problem or just an anomaly, samples were collected and analyzed for Mercury in the four weeks following the receipt of the initial test.
