Water Resources Board

MINUTES MURFREESBORO WATER RESOURCES BOARD January 22, 2019 The Murfreesboro Water Resources Board met on Tuesday, January 22, 2019 in the conference room at the Operations and Maintenance Building, 1725 S. Church Street. Present at the meeting were Board members: Mr. John Sant Amour, Dr. Al Carter, Mr. Ron Crabtree, Ms. Sandra Trail, Ms. Kathy Nobles, and Ms. Madelyn Scales-Harris. Also present were Darren Gore, Doug Swann, Valerie Smith, Michele Pinkston, Anita Heck, Adam Tucker, Steve Tate, Alan Cranford, Joe Russell, John Strickland, Jay Bradley, Mike Bernard, Lynda Sullivan, and Kyle Peters, along with other members of the public. The December 11, 2018 Board Minutes were unanimously accepted as presented. The Board considered contingency allocations for Ransom Drive Pump Station Replacement. The Department received bids for the Ransom Drive Pump Station Replacement on May 10, 2018 and the Board approved to award the project to SBW Constructors, LLC in the amount of $934,836 which included add alternate #1. As part of the project, Item #13 of the Construction Contract is a Miscellaneous Allowance of $10,000. Staff would like to allocate a portion of this Miscellaneous Allowance through a field work change directive. This work change directive does not change the contract price, only adjusts the remaining balance of the miscellaneous allowance. The following table is provided to update the Board on the current field work change directives and the remaining miscellaneous allowance. Project Miscellaneous Prior Allowance Current Allowance Remaining Allowance Allocations Allocations Miscellaneous Allowance Ransom Drive PS $10,000 $0.00** $5,174.00* $4,826.00 Replacements *WCD # – 1 (Current) **WCD #’s - none previously approved) Staff recommended the miscellaneous allowance in the amount of $5,174, for the Ransom Drive Pump Station Replacement be authorized. A final contract amount accounting for all miscellaneous items will be brought to the Board and City Council for approval in a future or final balancing change order. Kathy Nobles made a motion to approve. Madelyn Scales-Harris seconded. The motion unanimously passed. The Board considered purchase of a Fournier Rotary Biosolids Press. Page 31 Water Resources Board Minutes January 22, 2019 Page 2 The Water Resources Recovery Facility utilizes 8 Fournier Industry Rotary Biosolids Presses to dewater the sludge that is a byproduct of the wastewater treatment process. Currently, over 50,000,000 lbs. of dewatered sludge are trucked annually to the landfill by the Department for final disposal. The Biosolids facility was constructed in 1999 with four presses and commissioned in 2000. Of those presses, only one has not been replaced. However, after 19 years it also needs to be replaced. This request is for the purchase of the equipment only. The cost of installing the new press, through the Department’s standing contract with John Bouchard & Sons, is estimated at $74,000. A Task Order will be developed and brought to the Board for approval. Controls and Integration services from MR Systems should not be necessary. These are already in place. Staff will complete any minor adjustments. Also, new Original Equipment Manufacturer (OEM) parts are only available from a single source. The manufacturer’s distributor for this area is the Fournier Industries. Staff recommended approval to purchase one six-channel rotary press from Fournier Industries to replace an existing rotary press in the amount of $382,500 from rate funded capital. The purchase of the Fournier Rotary Biosolids Press was budgeted in the Department’s rate funded capital account in the amount of $480,000. Kathy Nobles made a motion to approve. Dr. Carter seconded. The motion unanimously passed. The Board considered John Bouchard and MR Systems Task Orders for Small-Scale Biosolids Dryer Installation. The Water Resources Board approved the procurement of a small-scale biosolids thermal drying unit from Gryphon Environmental, LLC at the June 2018 meeting. This purchase was to demonstrate how well the drying process would work if added to our process full scale prior to the onset of the landfill closure and the discontinuance of our biosolids disposal at the landfill in approximately 3½ to 5 years. The dryer is being manufactured and has an expected delivery date of late February. Staff expects to have the installation complete in approximately 6 months and that will give us approximately 12 months of operation before determining if this manufacturer would be recommended for a full-scale implementation. For this installation, SSR has received and evaluated Task Order proposals from John Bouchard and Sons (JBS-Task 19-02) and MR Systems (MR-Q18-5707 Rev. 2) through our Mechanical/Electrical Services Contract and Master Services Agreement respectively. Estimated costs associated with the installation and ancillary equipment presented in June 2018 totaled $196,000. SSR tabulated the original opinion of the construction costs as well as the updated and revised construction costs. The revised costs are $41,652.50 less than the original estimate. The revised estimate for all costs associated with the installation is $154,347.50, with JBS being $100,645.50 and MR being $24,492 of this amount. The remainder is made up of MWRD work, Demolition and Contingencies.

Staff has earmarked $750,000 in our 5-yr CIP for biosolids processing equipment and storage from reserves and also $1.8M in reserves through FY18, for a total of $2.55M. The cost of the Gryphon dryer was $865,000. The cost of SSR’s design fee is $133,725. Revised additional costs associated with installation and ancillary equipment equals $154,347.50; totaling $1,153,072.50. Annual operational costs are estimated as $48,000 ($18,000 O&M, $13,000 Natural Gas, $17,000 Electricity). Sandra Trail made a motion to approve. Kathy Nobles seconded. The motion unanimously passed. The Board considered a Resolution Adopting Revised Murfreesboro Water Resources Department Plant Protection Criteria and Local Industrial User Limits. The General Pretreatment Regulations (40 CFR 403) require that each publicly owned treatment works (POTW) that is required to develop an approved pretreatment system to also develop and enforce local limits on certain pollutants to protect against pass through or interference which may be caused by industrial discharges to the treatment facilities. EPA provides guidance manuals for developing these local limits. Local limits are most often associated with the control of toxic pollutants such as cadmium, chromium, copper, cyanide, lead, mercury, nickel, silver and zinc. The POTW must also identify all other pollutants of concern and evaluate the need for limits of these pollutants. A pollutant of concern is defined as any pollutant limited in the POTW’s NPDES permit or found in the collection system of sufficient quantity to have a reasonable potential to cause pass through or interference at the treatment plant, pose a threat to worker’s health and safety, or to cause other problems within the collection system or at the treatment plant, such as explosions or obstruction of wastewater flow. The Tennessee Department of Environment and Conservation (TDEC), Division of Water Pollution Control directed the Murfreesboro Water Resources Department to recalculate local limits and plant protection criteria (PPC) every five years to replace the said limits currently in place. New local limits and revised PPC have been developed based on the most recent pass through limits, flow into the plant, and removal efficiencies. Plant historical data and typical removal efficiencies as determined by EPA were used in the calculations. Public notice of the proposed new limits was advertised in the local newspaper in December 2018.

The Plant Protection Criteria (Section 1) and Industrial User Limits (Section 2) are in the resolution. Pursuant to Section 33-36(F) (1) the proposed revised Plant Protection Criteria and new Industrial User Limits may be adopted by resolution. Sandra Trail made a motion to approve. Dr. Carter seconded. The motion unanimously passed. Staff presented and discussed the Water Resources Dashboard Performance for December 2018. Staff presented the Financial Reports for the year ending December 31, 2018. There being no further business, the meeting was adjourned. John Sant Amour, Chairman Page 34
