All rights reserved. The Report will be revised in response to Owner’s comments, as appropriate, and furnish one (1) electronic copy of the revised Report and any other deliverables to the Owner within 14 calendar days of receipt of Owner’s comments. Engineer’s services under the Short-Term PFAS Minimization Plan Phase will be considered complete on the date when the revised Report and any other deliverables have been delivered to Owner. Task 103 – Phase 2 – Long Term PFAS Minimization Plan/Conceptual Design At each affected facility, identify intended solution strategy (wellhead management, decentralized wellhead treatment, or centralized treatment at the WTP). For locations requiring treatment, consider options for adsorptive media, including granular activated carbon (GAC), anion exchange (AIX), or FLUORO-SORB®. High pressure membranes (RO/NF) will not be considered due to cost, footprint requirements, and impacts to finished water quality. Engineer will use a decision-making matrix to identify a recommended adsorptive media based on review of available water quality data, spent media disposal considerations, and Owner goals and weightings as identified in the kickoff meeting. For any sites lacking sufficient data to support a recommended media, GAC will be selected as a conservative solution due to its larger footprint and capital costs, unless available footprint drives the need for AIX resin. Discuss those recommendations with the Owner during in an in-person workshop before proceeding with conceptual design. Prepare a report (the “Report”) which will, as appropriate, contain the following for each site: · For sites in which wellfield management is the solution, document operational strategy. · For sites in which treatment is required, prepare schematic layouts, sketches, and conceptual design criteria with appropriate exhibits. Provide of probable construction cost; high-level annual operation and maintenance (O&M) cost estimates using the Black & Veatch PFAS cost model; 20-year life cycle costs; and recommended next steps. · Recommended next steps, including demonstration testing for optimized media selection if applicable. Furnish one (1) electronic review copy of the Report to Owner within 90 calendar days of the Effective Date and review it with Owner. Within 14 calendar days of receipt, Owner shall submit to Engineer any comments regarding the Report and any other deliverables. Revise the Report and any other deliverables in response to Owner’s comments, as appropriate, and furnish one (1) electronic copy of the revised Report and any other deliverables to the Owner within 14 calendar days of receipt of Owner’s comments. Engineer’s services under the Long-Term PFAS Minimization Plan/Conceptual Design Phase will be considered complete on the date when the revised Report and any other deliverables have been delivered to Owner. Task 104 - Project Management and Administration Engineer will support the Owner by managing the project to coordinate evaluation of alternatives between engineering disciplines, monitor and control the project budget and schedule, and keep the Owner
