No. 0561-2050-6450-00000 Engineering & Consulting Fees City Oshkosh MEMORANDUM TO: Honorable Mayor and Members of the Common Council FROM: Justin Gierach, Engineering Division Manager/City Engineer DATE: January 9, 2020 RE: Approve Professional Services Agreement for 2020-2022 Illicit Discharge Detection and Elimination Outfall Screening and Revisions to the Ongoing Screening Program/OMNNI Associates,Inc. (OMNNI) ($79,545) BACKGROUND The Department of Public Works requested a proposal from OMNNI to perform the ongoing storm sewer outfall screening for 2020 - 2022. The ongoing field screening of storm sewer outfalls is required by the Wisconsin Department of Natural Resources (WDNR) under Wisconsin Administrative Code Section NR 216, and the City's Municipal Separate Storm Sewer System (MS4) General Permit WI-S050075-3. The WDNR administers this program in accordance with the United States Environmental Protection Agency Clean Water Act. The WDNR reissued the MS4 Permit in 2019. The latest version of the MS4 Permit contained updates and revisions to the requirements that municipalities must complete. The storm sewer outfall screening program is one program that had changes made to it, so OMNNI will assist the City in updating our outfall screening program to be in compliance with the newest version of the permit. ANALYSIS OMNNI was chosen based upon their experience in performing these services for the City of Oshkosh and for other communities within the Fox Valley region. OMNNI performed the initial field screening for the City of Oshkosh in 2009 and has completed the ongoing field screening since then. FISCAL IMPACT The cost of these services over the course of the three-year contract is estimated not to exceed $79,545. Funding for the 2020 services is available in the Storm Water Utility Operating Budget. Funding for future years' services will be included in the Storm Water Utility Operating Budget for each year.

This proposal is intended to present a work scope and cost estimate for our services. OMNNI Associates (OMNNI) proposes to review and evaluate the current ongoing outfall screening program for � the City of Oshkosh that was revised in2O15. Recommendations for revising the ongoing screening program � would consider the City's existing program, experience obtained from previous outfall screening inspections, � and the Illicit Discharge Detection and Elimination (IDDE) Guidance Document prepared by the Wisconsin � Department of Natural Resources (NDNR). Our recommendations would take into account the most current issuance of the General Permit to Discharge under the Wisconsin Pollutant Discharge Elimination System (MS4 Permit), so the revised ongoing screening program is compliant with any new requirements. VVe would meet | ! with the City to discuss our recommendations. Based on the outcome from the discussions withtheChy a revised ongoing outfall screening program would be prepared for submittal to the WDNR. OMNN| also proposes screening approximately 90 outfalls (of the approximately 426 outfalls) each year in years � 2020'2022. The outfalls screened would include outfalls identified in the City's ongoing program for the � current year and outfa|b identified in the previous year's inspection as requiring re-screening. Proposed Scope ofServices 1. Evaluate changes to the Cit/a current ongoing screening program. a. Update municipal separate storm water sewer system map. i Update outfaUs and storm sewer system. ii Provide a drainage basin for each oudaU. iii. Indicate flow direction for storm sewer. h. Evaluate the City/s current ongoing screening program to include experience obtained from previous outfoU screening inspections, input from City staff and new permit requirements. c. Develop a screening matrix to identify the proposed screening frequency for each identified oudaU for the City. d. Meet with City to discuss the draft revised ongoing screening program recommendations. 2. 2820-20%2stormvvate/outfaUscreening. � a. Update the illicit discharge GIS applications for the current year screening program. | | omnnixom | wrntwmodpm.cvm � � ' | Mr.James Rabe,pc. November 6,zu19 Page zms b. Conduct approximately 9UoutfaU inspections each year. OudaU inspections would include outfalls identified in the City's ongoing program for the current year and outfalls identified in � the previous year's inspection as requiring re-screening. i. For each outfall screened,the geographic location would be verified; a digital photograph showing general location and configuration would be taken; a digital photograph showing flow(or the absence of flow)would be taken; and physical data on the outfaUwould be verified. ii For inspected outfalls that are flowing 48 or more hours after a runoff-producing rainfall event,flow characteristics would be documented. � iii A sample of the stormvvaterwould be collected from outfaUo that are flowing 48or � � more hours after a runoff-producing rain event and analyzed using field tests and/or the Hach kit for stormwater. iv. Indicator parameters from the stormwatersample (parameters can include: pH, ! conductivity,temperature, ammonium,total chlorine, and detergents) would be � measured as outlined in the City ofOshkosh's Ongoing Screening Program. v. For outfalls that are partially or fully submerged,the stormwater sample would be collected from the next accessible upstream location. vi. If potential illicit discharge is detected,the City would be notified and provided with the data collected during the screening of the outfa|i c. Produce inspection reports for each outfall inspected that year, including general outfall characteristics and illicit discharge indicator parameters. d. Produce a program summary report each year describing the outfall screening procedures that � were followed, along with any potential illicit discharges that were discovered. e. Produce a summary report each year ofoudaUsthat have observed structural damage, significant deposition o/erosion, orgraffiti. [ Update the outfall map each year showing the locations of the identified outfalls. ' 8. Present a summary of the outfall screening to the Storm Water Utility Committee each year, if requested. ' / l Submittals/deliverables. � a. Revised ongoing screening program would be provided in hardcopy and PDF format. � b. 0udaU reports would be provided inhardcopy and PDFformat. � c. Outfall photographs and flow photographs would be provided to Client on a DVD-ROM. d. Outfall locations and screening results would be provided in ESRI shapefile. e. One color copy of the draft field screening summary report, including the oudaD reports for the sceenedoutfaUs. [ Two color copies of the final field screening summary report, including the outfall reports for the scmonedoutfaUs. � | A. Summary presentation of the outfall screenings to the Storm Water Utility Committee, if requested. � � Schedule � The proposed schedule for the work would generally bemsfollows: l. Conduct uutfaU screening during June—October,weather permitting. | 2.

Our estimate above is based on the previous level of effort we have provided the City. The contingency for tracking estimate is the same amount we have set aside in the past. City Support We recommend that the City provide OMNNI's field staff with identification badges and/or documentation authorizing our field inspection activities. We also recommend that the relevant city and county departments (police,fire, street, etc.) are informed of the field screening effort and our field presence. When screening submerged outfalls, one or more upstream manholes will likely need to be opened to allow for inspection and sampling. If any of these manhole covers are secured with bolts or locks,the City will be responsible for providing personnel to assist with opening the manhole for the inspection and securing them following the inspection. City assistance is not anticipated for manhole covers with no bolts or locks, unless required by the City. For high traffic areas, we may require City staff to assist with traffic monitoring and/or temporary diversion while the manholes are accessed. We have assumed that the City of Oshkosh will continue to provide ESRI shapefiles or CAD data of the storm sewer pipes and the major and minor outfall locations. We truly appreciate the opportunity to provide our services to the City and look forward to continue working with you on the City's stormwater screening, Please contact me at 920-830-6141 or bwayner@omnni.com with any questions or for clarification of our proposed approach. Sincerely, Brian D. Wayner, PE. Environmental Manager
