( 0 Of I-KO H ON THE WATER MEMORANDUM TO: Honorable Mayor and Members of the Common Council FROM: Stephan M. Brand, Utilities Superintendent DATE: June 3, 2009 RE: Wisconsin Department of Natural Resources 2008 Compliance Maintenance Annual Report City of Oshkosh Wastewater Treatment Plant BACKGROUND The City of Oshkosh is required by the Wisconsin Department of Natural Resources 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 Wisconsin Department of Natural Resources by June 30, 2009 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 Department of Natural Resources 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 provide. 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 2008 was June with a monthly average of 24.94 million gallons per day which is 71.2 percent of the design flow of 35 million gallons per day. Our normal months are closer to 32% of design flow or 11.2 million gallons per day. The treatment capacity is based on Biochemical Oxygen Demand in pounds per day. Our highest influent loading monthly average was 15,066 pounds in the month of May. Our design loading is 33,336 Ibs which puts us at 45.1 % 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, Ammonia, Phosphorus These four sections look at the quality of our treatment for each of these parameters based on our permit requirements. There were no treatment issues for any of these sections and each scored a letter grade A . 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 reused 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. Wisconsin Department of Natural Resources 2008 Compliance Maintenance Annual Report City of Oshkosh Wastewater Treatment Plant Page 2 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 Department of Natural Resources 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 that 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 was is required as a condition of the Clean Water Fund when financing projects through the Clean Water Fund Financial Assistance Program. 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 2008. Much of this section is subjective and based on planning and maintenance activities. Inflow and Infiltration issues are noted in questions seven and eight with a response for corrective action in question nine. Even though these issues are identified, there are no points associated with these questions. Based on this scoring system, the identification of the I &I during the June flooding does not affect the score and this section scored a letter grade A . Even with this grade, it is recognized that the collection system needs to be upgraded. The first phase of an Inflow and Infiltration Study is being undertaken by the Consulting firm McMahon Engineers /Architects and will help to begin addressing the larger concerns with the performance of the collection system. RECOMMENDATIONS I recommend approval of the Compliance Maintenance Annual Report 2008 for submittal to the Wisconsin Department of Natural Resources. Respectfully Submitted, Stephan M.
