( 0 OJHKO H ON THE WATER MEMORANDUM TO: Honorable Mayor and Members of the Common Council FROM: Stephan M. Brand, Utilities Superintendent DATE: June 8, 2011 RE: Wisconsin Department of Natural Resources 2010 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, 2011. 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 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 2010 was July with a monthly average of 24.32 million gallons per day which is 69.5 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 in pounds per day. Our highest influent loading monthly average was 15,911 pounds in the month of July. Our design loading is 33,336 Ibs which puts us at 47.7 percent of our design loading for the facility. Based on the available capacity of the facility this section scored a letter rag de 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. COMPLIANCE MAINTENANCE ANNUAL REPORT Influent Flow and Loading flows and (C)BOD load 12.
