No. 551-1940-6450-00000 Sewer Utility – Engineering & Consulting City of� Oshkosh MEMORANDUM TO: Honorable Mayor and Members of the Common Council FROM: Stephan M. Brand, Public Works Utility Bureau Manager DATE: February 23, 2017 RE: Engineering Services Agreement for Phosphorus Preliminary Compliance Alternatives Plan / CH2M HILL Engineers, Inc. (CH2M HILL) ($249,805) BACKGROUND On September 27, 2016 a settlement was approved with the Wisconsin Department of Natural Resources (WDNR) regarding the Wastewater Pollution Discharge Elimination System (WPDES) permit related to the discharge limits for phosphorus. The settlement set an interim permit limit of 0.8 mg/1 for phosphorus, which is achievable using our existing treatment technology. This limit is likely to change with the completion of a study that is underway to determine the Total Maximum Daily Load (TMDL) for dischargers to the upper Fox River, Wolf River, and Lake Winnebago. The limit could easily become less than the wastewater treatment plant's (WWTP) current capability for phosphorus removal. There are options available that can be used in place of WWTP facility upgrades. These options include adaptive management, water quality trading, and the multi -discharger variance. The permit requires that an evaluation of these options be investigated and submitted to the WDNR no later than December 31, 2017. ANALYSIS CH2M HILL has been providing technical support for both the WPDES permit negotiations and the analysis of modeling being used in the TMDL process. They also have extensive experience in evaluating options for meeting phosphorus limits for facilities in northeastern Wisconsin. This level of experience and knowledge will assist them in providing an effective and efficient evaluation of the options required by the WPDES permit for Water Quality Based Effluent Limits for phosphorus. FISCAL IMPACT This work will be funded with Wastewater Utility funds approved in the 2016 and 2017 Operating Budgets of the Wastewater Utility. RECOMMENDATIONS Chapter 12 of the Municipal Code of the City of Oshkosh provides that professional services of a specialized nature, including engineering services, may be procured without the use of formal, sealed quotes. I have reviewed the agreement and, in accordance with Section 12-16 of the Code, I am hereby recommending the Common Council approve this agreement. Approved, Mark A.
