Water Resources Board

MINUTES MURFREESBORO WATER RESOURCES BOARD July 23, 2024 _____________________________________________________________________________________ The Murfreesboro Water Resources Board met on Tuesday, July 23, 2024, in the conference room of the Operations and Maintenance Building, 1725 South Church Street. Present at the meeting were Board members: Mr. Ron Crabtree, Mr. Brian Kidd, Ms. Kathy Nobles, Mr. Warren Russell, Mr. John Sant Amour, Ms. Sandra Trail, and Mr. Kirt Wade. Also present were Valerie Smith, John Strickland, Michele Pinkston, Doug Swann, Darren Gore, Matt Powers, Donald Huges, Nathan Corum, Steve Campbell, Joe Russell, Jennifer Tag, Josh Upham, Brent Fowler, Linda Sullivan, and Travis Wilson, along with other members of the public. The Consent Agenda was presented to the Board for approval: A. Consider Salem Barfield Sewer Upgrades Contingency Allocation B. Consider SRWTP Grass Cutting & Landscaping Contract Amendment No. 3 C. Consider JBS Task Order 24-02, SRWTP Raw Water Pump #3 Service D. Consider WRRF Sodium Hypochlorite (Bleach) Contract Amendment E. Consider GE GlobalCare Software Support Purchase F. Consider Rockwell Automation TechConnect Support Purchase G. Consider Culp Cleaning Contract Amendment Kirt Wade made a motion to accept the Consent Agenda as presented and it was seconded by Warren Russell. The motion carried unanimously. The June 25, 2024 Board Minutes were accepted as presented. Staff requested extending the term of Task Order (TO) 2141013.0 for regulatory assistance and water quality management through June 30, 2025. The Board previously approved Amendment No. 1 of SSR TO 2141013.0 which added stormwater management consulting services. The term specified in Amendment No. 1 has expired. Amending TO 2141013.0 from July 1, 2023, through June 30, 2025, will provide time for assistance with policy documents resulting from ordinance revisions. These services have been beneficial in updating the stormwater chapter of City Code and many other technical documents. Amendment No. 2 only extends the term of the TO and does not propose any funds above the previously approved amount of $175,300. Sandra Trail made a motion to approve. Kathy Nobles seconded. The motion unanimously passed.

In June of 2022, staff reviewed a study conducted by SSR detailing the WRRF’s existing hydraulic capacity along with the necessary upgrades to handle the flows generated by peak wet weather events in the Department’s sanitary sewer collection system service area. In July 2022, the Board approved the Engineering design to upgrade the WRRF with additional filters, additional UV disinfection equipment and piping upgrades to bring the wet weather capacity of the WRRF from 60 to 80 million gallons per day (MGD). The estimated probable construction cost at that time was $8,150,000. Bids were received July 2, 2024, and staff received a recommendation of award from SSR and the bid tabulation. SSR has successfully worked with RY in the past and RY has also been awarded the Full- Scale Thermal Dryer project as well. The contract, $7,185,000, will be paid for through Working Capital Reserves. These wet weather upgrades will be usable as part of any future WRRF treatment expansion (e.g., oxidation ditch and clarifiers). Staff requests the Board to award the project to RY and recommend the Council approve of the contract based on Legal’s review and approval. Kathy Nobles made a motion to approve. Brian Kidd seconded. The motion unanimously passed. Staff recommends the Board to approve the sole source purchase of Pit Raider and Nutri Pro odor control from State Industrial Products. Since 2013, Operations & Maintenance has used State Chemical products to control odor complaints from the Saratoga Drive area. The odor comes from the Kensington Drive Pump Station which is fed by Tortuga Court Pump Station. The force main between these two pump stations is long and often experiences low velocity resulting in odorous and corrosive conditions. Pit Raider is a bacteria-based hydrogen sulfide treatment combined with a nutrient supplement furnished by State Chemical Products to keep these conditions under control. Pit Raider has demonstrated it can reduce hydrogen sulfide to a minimal level, virtually eliminating the odor and greatly reducing corrosive effects to the manholes. These chemicals are purchased and distributed through the Kensington Pump Station to control odor issues. Our odor complaints have diminished, and the department works closely with a state chemical representative to minimize costs by maintaining optimal feed rates during summer dry and winter wet months. The total annual expense last year, $28,147.11, will remain the same through FY25. The department has budgeted $55,000 in the operating account, Sewer Pump Station Operations -Odor Control. Brian Kidd made a motion to approve. Kirt Wade seconded. The motion unanimously passed.

The Operations & Maintenance Division received a quote from United Systems, a sole source provider within our region, for the purchase of 400 water meters to maintain adequate supply level as the lead time to receive these meters is 9 to 10 months. These meters will be used for replacements and new installations. The purchase, $74,000, will be paid from AMI’s FY25 Operating Budget for Meters/ERTs/MLog. Sandra Trail made a motion to approve. Kirt Wade seconded. The motion unanimously passed. MWRD is prepared to take the next step with TDEC in applying for an expanded NPDES discharge permit for the Water Resource Recovery Facility (WRRF). Hazen Sawyer’s and Smith Seckman Reid’s engineering expertise and associated aid are required to meet Tennessee’s antidegradation regulations to demonstrate that any increase in discharge from the WRRF will not lower the measurable instream dissolved oxygen (DO) concentration of the West Fork Stones River (WFSR). MWRD has been working on a water quality model for the WFSR since 2021 with Hazen Sawyer. This water quality model will be the foundation for the NPDES permit expansion and will demonstrate how the additional discharge from Murfreesboro’s WRRF would not degrade water quality criteria in the WFRS. The completed model was submitted to TDEC on July 11, 2024, and we expect their approval in the next several weeks. In preparation of that approval, Hazen Sawyer and Smith Seckman Reid have collaboratively provided the scope of work and fees for the necessary tasks to complete the preliminary engineering and permitting requirements that would ultimately allow for the next WRRF expansion; expected to start in the 2027-2028 timeframe. The most significant effort of work and associated costs is in conjunction with developing a calibrated process and capacity model for the WRRF and the preliminary engineering design of proposed improvements associated with the WRRF expansion. Hazen Sawyer’s proposal is provided as information only. Staff intends to bring contracts for the work to the next Board meeting. The total fees associated with the five separate tasks is $879,000. A $15,000 expense contingency takes the total estimated costs to $894,000. Staff presented the Water Resources Dashboard Performance for June 2024. There being no further business, the meeting was adjourned. _____________________________ John Sant Amour, Chairman Page 18
