All rights reserved. <br /> <br />This is EXHIBIT A, consisting of 15 pages, referred to in <br />and part of the Agreement between Owner and Engineer <br />for Professional Services dated , . <br />Engineer’s Services <br /> <br />Article 1 of the Agreement is supplemented to include the following agreement of the parties. <br /> <br />Engineer shall provide Basic and Additional Services as set forth below. <br /> <br />PART 1 – BASIC SERVICES <br />A1.01 Study and Report Phase <br />A. Engineer shall (standard text deleted and new text inserted): <br />United States Environmental Protection Agency (US EPA) promulgated the first national primary drinking <br />water regulation (NPDWR) for six (6) per- and polyfluoroalkyl (PFAS) compounds (including PFOA, <br />PFOS, PFHxS, PFNA, PFBS, and GenX chemicals) on April 10, 2024. All public water systems will be <br />required to begin monitoring and reporting in 2027, and public water systems are required to be in <br />compliance with the maximum contaminant levels (MCLs) by 2029. <br /> <br />The Owner owns and operates nine water treatment plants (WTPs), including Cleveland North, Cleveland <br />South, Carriage Hills, Pinhook, North, Edison, Olive, South, and Erskine. Several rounds of PFAS <br />monitoring were conducted in 2023 and 2024 in the raw water wells and finished water at each WTP. The <br />Owner provided data with 2023-2024 finished water results which showed exceedances of PFAS MCLs at <br />the North WTP and Pinhook WTP. The Owner also provided raw water results for 2024 for comparison <br />to the MCLs. The data indicated contamination to concentrations exceeding the MCLs in the raw water <br />wells at the Pinhook, North, Olive, and South WTPs. In the absence of finished water PFAS <br />concentrations above the MCLs at the South and Olive WTPs, it appears the current operational strategy is <br />effectively producing finished water within regulatory limits by taking affected wells offline, but this <br />needs to be further studied. <br /> <br />The focus of the PFAS Minimization Evaluation is to complete the following phases: <br />1. Short-term Strategies: Engineer shall first study the available data from all water <br />production wells and WTPs to determine a short-term operational strategy to minimize <br />finished water PFAS going to the distribution system. <br />2. Long-term Strategies: Consultant will identify solutions, including bulk treatment at the <br />various WTPs or opportunities for potential wellhead treatment. Engineer will develop <br />conceptual designs and life cycle costs for up to four sites. Conceptual treatment design at <br />additional sites can be added as a supplemental service. <br />Task 101 – PFAS Minimization Study Kickoff and Data Review <br />Engineer will conduct a kickoff meeting with Owner to define and clarify Owner’s requirements for the <br />Project, finished water quality goals, and available data. Engineer will work with the Owner to develop <br />ratings for various criteria for the future decision-making matrix.
