Lower Neuse WTP Project Advisor

Page 1 of 5 Request for Qualifications Johnston County Lower Neuse WTP Project Advisor March 7, 2024 Statement of Qualifications Due by: April 18, 2024 5:00 pm Johnston County Department of Public Utilities 309 E. Market Street Smithfield, NC 27577 Page 2 of 5 NOTICE REQUEST FOR QUALIFICATIONS JOHNSTON COUNTY Lower Neuse Intake and Lower Neuse WTP Project Advisor Deadline: April 18, 2024, at 5:00pm The Johnston County Department of Public Utilities (JCPU) is seeking statements of qualifications from qualified consultants to serve as a project advisor to the County for the Lower Neuse Intake and a Lower Neuse WTP in Princeton, NC. A selection panel will review and evaluate the qualifications statements and select a single consulting firm for this project. Background Johnston County provides potable water supply to sixteen water districts and the Towns of Clayton, Wilson’s Mills, Archer Lodge, Kenly, Princeton, and Four Oaks. The County provides supplemental supplies to the Towns of

Selma, Pine Level, Micro, Benson, Smithfield, and Fuquay-Varina (in Wake County). In addition to supply from the Timothy G. Broome Water Treatment Plant (WTP), the County purchases water for distribution to its customers from the Town of Smithfield, Harnett County, Wayne County Sanitary Districts, the City of Wilson, Sampson County, the City of Raleigh and, under emergency conditions, the Town of Benson. The County’s Timothy G. Broome Water Treatment Plant is centrally located in Wilson’s Mills. Its source is the Neuse River. The intake and treatment facility are located one half mile east of the Town of Wilson’s Mills. There are two reservoirs on site. Each reservoir has a storage capacity of 35 million gallons. The treatment system has six main steps to remove and reduce harmful contaminants: presedimentation, organic carbon removal through magnetic ion exchange, coagulation, clarification, filtration by multimedia high rate filters, and disinfection. Once treatment is complete, water is pumped into elevated storage tanks for distribution throughout the water system. A project is underway to upgrade the existing plant from 14.0 MGD to 18.0 MGD. The withdrawal from the Neuse River at this site is limited to 17 MGD. A long term water supply study is underway and nearing completion. Results show that the County will need to double its water supply capacity within the next 10-12 years. Project Description The proposed project will include: • The Lower Neuse Intake (near the Richardson Bridge Road crossing of the Neuse River) • An approximately 14 mile raw water transmission system from the Lower Neuse Intake to the County owned abandoned quarry and adjacent land north of Princeton. • The conversion of the County-owned 0.8 billion gallon abandoned quarry as a water supply storage facility. • A new 12 MGD WTP, expandable to 30 MGD, on the County-owned land north of Princeton. • Finished water transmission to US 70 and to Rains Mill Road. The project is to be placed in operation in 2029. Previous and Concurrent Efforts Hazen and Sawyer are nearing completion of a Long Term Water Supply Plan for the County. The final draft will be ready this Spring. The study looks at historical and predicted growth, projects water supply needs, evaluates alternatives for meeting those needs and recommends a path forward. The plan recommends that the County establish the Lower Neuse Intake and construct a new WTP adjacent to the County owned abandoned quarry using those 0.8 billion gallons as water supply storage. Page 3 of 5 The County has been planning for the Lower Neuse Intake and the new WTP at the quarry site for a long time. The Lower Neuse Intake had the approval of the Division of Water Resource (DWR), and a FONSI was issued in 2006. The 2006 FONSI has since expired but efforts are underway to update the hydrologic study and FONSI. Both have been submitted to DWR, and approval is expected later this year. A copy of the final Lower Neuse Water Supply Hydrologic Modeling Report is included in this RFQ package (Exhibit A). As part of the earlier effort, the County established a water supply watershed for the intake and the quarry. Zoning classifications in the area were modified to accommodate the designation. Hazen and Sawyer maintains the County’s systemwide hydraulic model. The County recently updated and recalibrated the model. Hazen is working on modeling future conditions and a plan for moving finished water from the new WTP location to the areas of demand predicted within the service area. Most of the required improvements will be rolled into a capital improvement program separate from this effort. Preliminary results show that at least two major transmission mains will be required at the start-up of the new facilities. Major transmission lines from the new WTP to US 70 and to Rains Mill Road will be required. The sizing of these lines and the operating conditions of the finished water pumps will be provided to the engineer from the model results. The future model results are expected later this year. Anticipated Scope of Services Stage 1 - Project Development – 7 Months Task 1: Preliminary Site Planning Given the long term needs established in the study, the consultant will conduct preliminary site planning for the current 12 MGD WTP project and future expansions to 30 MGD at the treatment plant site. Preliminary planning for the Lower Neuse Intake will include a constructability, permitting and operational assessment of site alternatives for the intake and pumping facilities. Task 2: Treatability Study The County has begun collecting quarterly raw water samples at the Lower Neuse Intake location (Exhibit B). Using this data, the consultant will develop a plan for effective treatment to current and anticipated upcoming drinking water standards. Alternatives for treatment will be evaluated on effectiveness, operation and maintenance requirements, and cost. A cost benefit analysis of possible effective treatment processes will be required. Task 3: Site Permitting The consultant will determine the permitting needs for the construction of a water treatment facility on the County owned property. Known issues remaining to be addressed are underground fuel storage tanks on-site and NPDES permitting for the waste stream from the future treatment process. The consultant will start the process of acquiring key permits identified. Task 4: Project Make Up and Scope An undertaking this large may require a collection of design and construction projects to complete. The Consultant will recommend a scope and delivery method for each component of the project. The consultant shall support the analysis and selection of a delivery method to accommodate the budget, schedule, and project goals. Analysis should include risk assessment, a clear outline of regulatory requirements and approvals required, and an analysis of how the delivery method impacts funding options. Stage 2 - Project Delivery and Contracting – 5 Months Task 1: Development of RFQs The consultant shall develop an RFQ for the County’s selection of a design or design-build team for each component of the project that clearly defines the project objectives and priorities, as well as owner expectations. The RFQ shall meet all regulatory and funding requirements and include clear selection criteria. During the RFQ process, the consultant shall Page 4 of 5 assist in answering questions, issuing addenda, and facilitating interviews, as needed. The consultant will also advise the County during the submission review process. Task 2: Contracting The consultant shall assist in the development of a contract with the selected design and/or design build teams. The consultant will help the County avoid pitfalls and develop a contract with appropriate risk and opportunity assignments to bring the project in within budget. Stage 3: Project Management Support – Until project completion in 2029 The consultant will assist the County in the development of a project execution plan. Throughout the project, the consultant shall facilitate project and progress review meetings, monitor costs, and minimize project disputes. Upon completion, the consultant will assist in project closeout documentation.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.
