DATE: June 23, 2016
RE: Approve and Submit 2015 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 and submitted to the WDNR by June 30, 2016.
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 2015 was December with a monthly average flow of 15.92
million gallons per day, which is 45% of our design flow of 35 million gallons per day. Our normal months
are closer to 36% of design flow or 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 14,916 pounds in the month of July. Our design loading is 33,360 pounds, which puts us at
44.7% 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 (Biological Oxygen Demand), 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, or
Ammonia. The section for BOD, TSS, Ammonia, and Phosphorus 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 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 facilities have certified operators on staff to operate and
manage a wastewater treatment facility and 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 Division and
Engineering Division based on the activities reported for sanitary sewer maintenance and construction in
2015. 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 (CIP). 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 2016 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 Phase II was completed in 2015 and included adding
all of the smaller diameter sanitary sewers to complete the City -wide sanitary sewer system model. This
model is being 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 2015 Compliance Maintenance Annual Report for submittal to the WDNR
