Date: October 26, 2015 Re: EPA/ IDNR Consent Decree Consent Decree (CD) Remedial Measures and Schedules (Article V.) A. Short-term Remedial Measures i. SSO Signage (CD Appendix 2) This requirement of the CD has already been addressed by WMSD. Signs will stay up for one (1)week following a Sanitary Sewer Overflow(SSO). ii. Footing Drain Removal Program in Service Areas 15, 16, 18 and 19 According to Craig Clark, approximately 1,688 footing drains have been removed in Services Areas 15 and 16 to-date. No footing drains have been removed to-date in Service Areas 18 and 19. B. Capacity, Management, Operations and Maintenance (CMOM) Program This requirement of the CD has been addressed by WMSD through preparation of a CMOM Program Plan. WMSD personnel, under the supervision of CMOM Supervisor Mark Brandes, will implement the provisions of the CMOM Plan. Periodic reports, including any substantive updates, changes or revisions to the CMOM Program Plan, will be submitted to state and federal agencies. C. SSORP Program (CD Appendix 4) This requirement of the CD is being handled by WMSD personnel under the supervision of Brian Rath. The only reported SSO so far in 2015 occured in May when a sanitary sewer pipe broke at ConAgra creating a small pool of wastewater near the broken sewer. D. Rainfall & Flow Monitoring Program (CD Appendix 5) This requirement of the CD will be handled by WMSD personnel, including the WMSD Instrument Control Technicians (ICTs). WMSD plans on purchasing the necessary rainfall and flow monitoring equipment for long-term use. Engineering assistance from an outside consultant, most likely AECOM, may be needed for data analyses and reports. E. Sanitary Sewer System Condition Assessment (CD Appendix 6) This CD requires a targeted inspection and assessment of the condition of the gravity sewer mains, manholes, pumping stations and forcemains within the sanitary sewer system. Investigation activities include; • Smoke testing • Televising • Dye testing • External building inspections CITY WEBSITE: www.cityofwaterlooiowa.com WE'RE WORKING FOR YOU! An Equal Opportunity/Affirmative Action Employer Manholes, gravity sewer mains, pumping stations and forcemains within Service Areas 15 and 16 must be assessed by September 30, 2016 and the results reported to EPA/ IDNR by December 31, 2016. Manholes, gravity sewer mains, pumping stations and forcemains within those portions of Services Areas 10, 11, 12, 13 and 19 determined by the City using best engineering judgement to have excessive wet-weather flows, must be assessed and results reported by December 31, 2017. All other condition assessments will be conducted as called out in the approved Master Plan which must be submitted by December 31, 2017. F. Sanitary Sewer System Hydraulic(SWMM) Model (CD Appendix 7) This requirement of the CD will be handled by an outside consultant, most likely AECOM. Currently, AECOM is under contract to create a hydraulic model of the sewer system. To comply with the final provisions of the CD, the following additional hydraulic modeling work is required: i. To Be Completed by February 29, 2016 • Validation of the Dry Weather Flow predicted by the model. • Validation of Wet Weather Flow data from three (3) storm events. • Simulation of the performance of the sewer system during the 2-year, 5-year, and 10-year rainfall events. ii. To Be Completed By August 31, 2016 • Submit final model calibration report to EPA. iii. To Be Completed By December 31, 2017 and each subsequent year as needed • Update hydraulic model based on latest rainfall and flow data The Hydraulic Modeling efforts by AECOM will be supervised by the Wastewater Supt. and CMOM Supervisor. G. Sanitary Sewer System Capacity Assessment (CD Appendix 8) This requirement of the CD will be handled by an outside consultant, most likely AECOM. This Capacity Assessment will look at existing conditions as well as projected population growth and flow rate growth for the next 20 years. i. To Be Completed By December 31, 2016 • Capacity Assessment of Service Areas 15 and 16 ii. To Be Completed By December 31, 2017 • Capacity Assessment of Service Areas 18 and 19 The Capacity Assessment efforts by AECOM will be supervised by the Wastewater Supt. and CMOM Supervisor. H. Sanitary Sewer System Master Plan (CD Appendix 9) This requirement of the CD will be handled by an outside consultant, most likely AECOM. The Master Plan work by AECOM will be supervised by the Wastewater Supt. and CMOM Supervisor. The deadline for submitting the Master Plan to EPA/IDNR is December 31, 2017. The remedial measures called out in the Master Plan must be completed no later than December 31, 2032. The schedule for implementation of remedial measures called out in the Master Plan must be broken down into 3-year time blocks in which each project will be completed. CITY WEBSITE: www.cityofwaterlooiowa.com WE'RE WORKING FOR YOU! An Equal Opportunity/Affirmative Action Employer II. Priority Capital Improvement Projects Related To Consent Decree a. Cured-In-Place Pipe (CIPP) Phase III Project The Phase II CIPP Project is about 70%complete at this time. Remaining identified needs in Service Areas 15& 16 will be included in a Phase III CIPP Project. Work on the Phase III CIPP Project would likely start in late 2016 or early 2017. b. Dry Run Interceptor& Pumping Station This project involves upgrading the Tower Lift Station and a new forcemain between the Tower Lift Station and the Hawkeye Lift Station. These improvements will reduce the wastewater hydraulic load on the conveyance and pumping components in Service Area 19, in the area along 9th Street. Design engineering on this project is complete. The plans and specifications are currently under review by IDNR. The project will be bid over the winter of 2015—2016 with construction beginning in the spring of 2016 and continuing into 2017. c. Titus (Midland) Pumping Station and Forcemain This project involves upgrading the Titus(Midland) Lift Station and a new forcemain between the Titus Lift Station and Park Road Lift Station service area. These improvements will reduce the wastewater hydraulic load on the conveyance and pumping components in Service Area 10. This project will not take place until after the hydraulic modeling of the sewer system is completed by AECOM. Final design of the project will likely be conducted by Claassen Engineering, which was the firm that provided a previous design for improvements to the Titus Pumping Station. The estimated construction start date is late 2017 or early 2018. d. Flow Equalization (FEQ) Basin Overflow Connection This project involves a new 24-inch diameter connection between the Flow Equalization Basins and the Satellite Treatment Units at the WWTF. This project will reduce or eliminate sewer system overflows (SSOs)occurring at the WWTF. AECOM is currently designing the connection. The project should be ready for bids during the winter of 2015 — 2016. Construction should start in the spring of 2016 and should be completed by the end of 2016. e. Long-Term Flow Monitoring Equipment (See Item I.D above.) This equipment will be purchased during the winter of 2015—2016 so it can be used to collect data during the spring/summer of 2016. III. Environmentally Beneficial Project Appendix 3 of the CD contains criteria for an environmentally beneficial project which, if undertaken and completed by the City of Waterloo, could receive funding up to the amount of fine collected by IDNR as part of the CD. The IDNR portion of the fine which could be reimbursed to the City is $136,000. WMSD and the City Engineering Department are collaborating on a project which would provide new pervious pavement surfacing in the downtown area. It is hoped that this project, which would reduce stormwater runoff to the Cedar River, will meet the criteria contained in Appendix 3 of the CD. The ballpark cost of the pervious pavement project is$136,000. CITY WEBSITE: www.cityofwaterlooiowa.com WE'RE WORKING FOR YOU!

The IDNR portion of the fine which could be reimbursed to the City is $136,000. WMSD and the City Engineering Department are collaborating on a project which would provide new pervious pavement surfacing in the downtown area. It is hoped that this project, which would reduce stormwater runoff to the Cedar River, will meet the criteria contained in Appendix 3 of the CD. The ballpark cost of the pervious pavement project is$136,000. CITY WEBSITE: www.cityofwaterlooiowa.corn WE'RE WORKING FOR YOU! An Equal Opportunity/Affirmative Action Employer
