Water Resources Board

MINUTES MURFREESBORO WATER RESOURCES BOARD June 23, 2020 The Murfreesboro Water Resources Board met on Tuesday, June 23, 2020 in the conference room at the Operations and Maintenance Building, 1725 S. Church Street. Consistent with the Governor’s Executive Order, members of the Water Resources Board participated by electronic means as has been determined necessary to protect the public health, safety, and welfare in light of the COVID-19 pandemic. Present at the meeting were Board members: Mr. John Sant Amour, Mr. Ron Crabtree, Dr. Al Carter, Ms. Sandra Trail, Ms. Kathy Nobles, Mr. Kirt Wade, and Ms. Madelyn Scales-Harris. Also present were Darren Gore, Michele Pinkston, Roman Hankins, Robert Haley, Ryan Potts, Marshall Fall, Steve Tate, Sharon Seibert, Donald Hughes, Jimmy Stacey, Matt Powers, Alan Cranford, Joe Russell, John Strickland, Randy McCullough, Brent Fowler, Linda Sullivan, Mike Bernard, and Ronnie Martin along with other members of the public. The Consent Agenda was presented for the following considerations: A. Consider renewal of Memorandum of Understanding with MTSU – Public education and participation are a core requirement of the State-issued stormwater discharge permit under which the City of Murfreesboro operates. The City’s annual report to TDEC includes a record of the outreach and education done during the year. In 2011, the City and MTSU entered into a memorandum of understanding (MOU) for MTSU to do education projects for us related to stormwater and surface water quality. We have continued with that MOU by annual renewals since then. The MOU sets a base amount of $45,000 and allows up to $60,000 in payments by the City to MTSU. Each year MTSU and the City plan for a set of projects and events that MTSU will work. These include education and outreach targeted to selected businesses or properties (for example, adjacent a stream); activities (TV spots, stream clean-up events, tree-planting, and follow-up education, etc.); classroom teaching; and setting up and staffing outreach events (Earth Day, school field days, etc.). Projects vary from year to year. Staff would like to renew the MOU without changes and recommended that the Board recommend to City Council renewal of the MOU. The 2020-21 fiscal year budget included $50,000 for the MTSU education services and would be paid out of stormwater funds. Page 21 Water Resources Board Minutes June 23, 2020 Page 2 B. Consider ADS Professional Services Contract Year 1 extension – Currently the Department is contracted with ADS, LLC to operate and maintain the Department’s 19 permanent sewer flow monitors and seven rain gauges, to analyze data recorded from these monitors and to report on this data annually. These annual reports, report wet and dry weather capacities and rain dependent inflow and infiltration (RDII) for 18 flow monitor areas. They also are contracted to perform temporary flow monitoring, analyze the temporary data recorded and report findings as well as perform field investigations. The current Professional Services Contract is nearing the end of its first year which is June 30, 2020. There is an option to extend for two additional one-year periods, with pricing for Years 2 & 3 being established on the consumer pricing index (CPI) for the southern region. The proposed extension adjusts pricing 1.4%. Staff desires to continue to contract their professional service as we have in various forms over the last 27 years. Staff recommended accepting the renewal of the ADS contract for a one-year period. The use of the quantities/units listed in the contract will be within the estimated budget amount for 2020-2021 of $300,000. The Long-Term Monitoring and Temporary Flow Monitoring quantities/units are completely used; however, the field inspections change from year to year, so this portion of the total is used within the budgeted amount. C. Consider revision to CUD/MWRD boundary – Staff proposes to swap a small area, within the Stones River National Battlefield along Wilkinson Pike, with Consolidated Utility District (CUD). It is unclear why this area was not included with a previous land swap since MWRD serves the surrounding area. CUD agrees with this swap and requested to bring this to the Board to “clean up” the boundary. Amendment document #6 will be prepared by our Legal Department to be executed by both parties. Staff recommended that the Board recommend that City Council approve the revision to the CUD/MWRD boundary and the Mayor executing an amendment to the Water Service Boundary. D. Consider Tiger Hill, Mill St., Halls Hill Water Tanks Change Control Form 1 – Change Control Form (CCF) No. 1 is for necessary changes to the scope of work to complete the project. These changes will come from the contingency amount in the contract. The approved changes are for items at the Mill Street, Halls Hill and Tiger Hill water tanks. SSR and staff have reviewed the cost associated with CCF No. 1 and concur that all charges are fair. The cost for Change Control Form No. 1 is $9,985. The contract has a contingency of $175,000 for this project. The remaining contingency amount after Change Control Form No. 1 is $165,015. A motion was made by Kirt Wade to accept the Consent Agenda as presented and it was seconded by Dr. Carter. The Board voted unanimously to approve. Page 22 Water Resources Board Minutes June 23, 2020 Page 3 The May 26, 2020 Board Minutes were unanimously accepted as presented. The Board considered sole source Rotork tank actuator modifications purchase. Staff is requesting to purchase equipment components for the existing actuators at each of the water storage tanks. These modifications will allow the controlling of the actuators by allowing them to modulate or allow partial opening/closing capability as opposed to fully open or fully closed. Each tank has a pre-existing Rotork actuator. The 4-20 mA kit purchase and install is required to be performed by Eco-Tech, Inc. through a sole source procurement. Eco-Tech, Inc. is the only authorized points of sale for Rotork actuators, control systems, parts and services in Tennessee. The Stones River Water Treatment Plant (SRWTP) fills a single pressure plane that then stores water in five distribution storage tanks (DSTs) spread throughout the service area. Unfortunately, because each tank is located at different distances from the SRWTP and the demands in the areas surrounding each tank vary, the tanks fill and drain at different rates. Certain customers near the SRWTP experience very high-water pressure and staff believes the distribution system loses a lot of water through leakage in these high-pressure areas. In order to alleviate these challenges, a solution was proposed in the Water Resource Integration Plan (WRIP) that would add two booster pumping stations near the Tiger Hill and Stoney Meadows DSTs to fill these tanks more quickly. The estimated one-time capital costs were $870,000 with $7,500 annual operating costs. A better solution has been identified. By modifying the actuators which allow them to modulate, or partially open and close, Specific Energy’s Distribution System Optimizer (DSO) system can be incorporated to better manage the filling and draining the DST’s. The DSO solution will allow the filling of the Tiger Hill and Stoney Meadows tanks faster, balance the hydraulics of the system to reduce peak pressures (which is anticipated to reduce water loss in the system), reduce pressure surges by controlling the speed of opening and closing of the valves on each tank, and will integrate the distribution system water quality to the operation of the high service pumps to improve both water quality and energy efficiency. The proposed cost of the DSO solution is estimated at $150,000, including the first year of annual service for the software interface, communications, updates, and data storage. After that, the annual service will cost $8,000 per year. The DSO solution is expected to afford the department over $700,000 in cost savings. The costs associated with modifying the actuators at each of the tanks, including installation, is $24,300. These improvements have been budgeted in the Department’s FY21 capital expenditures in the amount of $32,000. Staff recommended the Board recommend to the City Council approving the sole source purchase from Eco-Tech, Inc. in accordance with their quote. Sandra Trail made a motion to approve. Dr. Carter seconded. The motion unanimously passed. Page 23 Water Resources Board Minutes June 23, 2020 Page 4 The Board considered SSR Task Order 09-47-001.2, Amendment No. 7 for bioassessment monitoring of the West Fork Stones River and stratification study of J. Percy Priest reservoir. AquAeTer has completed its water quality and stream assessments for the West and East Fork Stones River commissioned for 2014-2019. The bioassessment monitoring results were very encouraging and demonstrate that the West Fork Stones River is healthy and meeting its designated uses. Staff believes the task order is necessary to continue this work through the summer of 2020, as a next installment of developing the protocol that we believe will help create a new permitting framework for the City of Murfreesboro with the Tennessee Department of Environment and Conservation (TDEC). All results demonstrate the West Fork is exceeding the standard for Tennessee Macroinvertebrate Index (TMI) of 32 of Murfreesboro’s ecoregion. Additionally, the assessments demonstrate that the effluent being discharged from the Water Resource Recovery Facility (WRRF) is not impacting stream health. TMI scores assess biological integrity of streams. Macroinvertebrates are used by TDEC as indicator organisms to determine if a stream supports fish and aquatic life. The continued sampling efforts and TMI scores are intended to support the strategy of approaching TDEC to offer alternate permitting potentials to the City of Murfreesboro as we attempt to get ahead of the growth projected in the City’s Murfreesboro 2035 Comprehensive Plan. One of the main overarching goals that the Department has over the next 20 years is to influence the regulatory framework focusing on reclaimed water. In addition to the macroinvertebrate sampling, staff has asked AquAeTer to conduct another stratification study of J. Percy Priest. This study is to demonstrate that during stratified conditions in the reservoir, the phosphorus being discharged from Murfreesboro’s WRRF is not getting into the lower reaches or deeper part of the lake where Smyrna is withdrawing water to supply their drinking water plant. Past assertions have been made that phosphorus from Murfreesboro’s WRRF had been getting to the bottom of the lake during summertime conditions, binding with manganese, and causing problems at Smyrna’s drinking water treatment plant and creating “black” water discharge at certain residents. Staff recommended that the Board approve Amendment No. 7 to SSR Task Order 09-47-001.2 to allow for continued biological sampling of the West and East Fork Stones River. The extension to the stratification study is a net additional fee of $108,800 from previous approved fee ceilings. Staff recommended funding coming from the Department’s working capital reserves. MWRD’s 5-yr CIP earmarked $150,000 for Stones River Water Quality studies for FY21. Dr. Carter made a motion to approve. Kirt Wade seconded. The motion unanimously passed. The Board considered SSR Task Order 18-41-009.0, Amendment No. 1 for Overall Creek Pump Station Upgrade additions. The Board previously approved various upgrades to the Overall Creek Pump Station due to equipment age. The approved upgrades included new variable frequency drives (VFDs), a new Human Page 24 Water Resources Board Minutes June 23, 2020 Page 5 Machine Interface (HMI), new local network switch, and new 240-watt, 24 volt DC power supply; a new stand-alone bubbler level system; a new backup ultrasonic level system; and a new cellular remote terminal unit (RTU). JBS Task Order 18-06 and MRS agreement were approved at the December 11, 2018 Board meeting. SSR Task Order 1841009.0 was approved at the June 26, 2018 Board meeting. During SSR design, staff requested additional upgrades to the station to improve station functionality, operation, and maintenance. These additional upgrades include replacement of old and problematic check valves, a new permanent bypass pumping connection, and structural evaluation and design of a new wet well cleaning access way. These upgrades were requested and authorized on August 20, 2018. Staff brought the re-budgeting information to the Board last month detailing the additional scope of work and updated cost estimates. Staff recommended the Board recommend City Council approve SSR additional design services related to the upgrades project, as well as John Bouchard & Sons revisions to Task Order 18-06 for additional construction activities itemized in their proposal and MR Systems performing additional controls and integration services. The estimated recommended additional upgrades cost is $173,680.90 consisting of $102,248.90 for soft starters removal and replacement, $56,987 for control panel upgrades, and $14,445 for additional engineering services. The total estimated project cost with additional services is revised to $559,372.96. Dr. Carter made a motion to approve. Kirt Wade seconded. The motion unanimously passed. Under Other Business, the Board considered Outside City Sanitary Sewer request for a proposed Rutherford County Fire and EMS station. Rutherford County has requested outside city sewer service for a proposed County Fire and EMS Station on Rockvale Elementary School property. Sewer service to this facility meets consideration criteria due to a Fire and EMS Station meeting a higher benefit to the public than annexation affords: Staff recommended the Board recommend approval to City Council serving the proposed Rutherford County Fire and EMS Station as an outside the City sewer customer. Sandra Trail made a motion to approve. Dr. Carter seconded. The motion unanimously passed. Staff presented and discussed the Water Resources Dashboard Performance for May 2020. Staff presented the Financial Reports for the year ending May 31, 2020. There being no further business, the meeting was adjourned. John Sant Amour, Chairman Page 25
