Paul Cross, PE, Principal ATTEST: Debra C. Barham, City Clerk APPROVED AS TO FORM: Kerr Ferguson Law, PLLC, City Attorney 1 4/14/2025 9:04:58 AM J:\Data\PSC\25-0072\00 Contract\PSA_SOW_WPWTP Phases 3 and 4.docx Scope of Work City of Pasco West Pasco Water Treatment Plant 18 MGD Expansion Phases 3 and 4 Design April 2025 Background The City of Pasco (City) is growing rapidly and its potable water demands are increasing with population growth and local industries. The City has two water treatment plants (WTPs) on opposite ends of its distribution system. While these plants can accommodate current and short -term peak demands together, individual plant capacity must increase to meet the City’s 20 -year planning projection. The West Pasco Water Treatment Plant (WPWTP) was designed to accommodate equipment expansion within the facility, and provides a cost-effective way for the City to handle growth. Previously, the City expanded the WPWTP capacity from 6 million gallons per day (MGD) to 12 MGD in two phases. Phase 1 increased treatment capacity to 12 MGD, including the installation of additional raw water strainers and membrane filtration units, filter-to-waste capabilities, a process residuals treatment and recycling system, and various plant operational improvements. Phase 2 increased pumping capacity at the raw water Intake Pump Station to 12 MGD, added a new High Service Booster Pump Station (BPS) with additional Zone 3 pumps, and improved electrical power redundancy for the Intake Pump Station and WPWTP. The City has asked RH2 Engineering, Inc., (RH2) to provide engineering design services for Phases 3 and 4 expansion of the WPWTP. A list of approximately $21 million worth of necessary improvements have been identified by the City, which exceeds the City’s budget for Phases 3 and 4. For this reason, a scoping workshop was held on December 3, 2024, between the City and RH2 to prioritize project elements for Phases 3 and 4, including a base list of treatment capacity related improvements and a list of non-capacity functionality improvements that may be incorporated into the final design budget. The base improvements identified to be designed as part of the Phased 3 and 4 improvements include the following: •Installing two (2) 3 MGD membrane filtration units (Membrane Rack Nos. 5 and 6). •Replacing the existing membrane modules on Membrane Rack Nos. 1 and 2. •Upgrading Membrane Rack Nos. 1 and 2 to replace problematic/antiquated plastic module header components (e.g., Victaulic couplers) with updated metal materials matching Membrane Rack Nos. 3 and 4. •Installing one (1) Intake Pump Station pump and associated piping, valves, and appurtenances.

As discussed at the scoping meeting, the project will be separated into preliminary design and final design. The preliminary design will include 30-percent design of the base improvements. A detailed Engineer’s opinion of probable construction cost (OPCC) will be prepared and reviewed with the City to determine if the City’s budget can accommodate additional non-capacity related improvements. If it is determined that the City’s budget cannot accommodate the base improvements, upgrading the treatment plant HVAC system will be removed from the project scope. If it is determined that additional project elements can be accommodated within the City’s budget, RH2 will add the following project elements to the design in the prioritized order listed: 1. Installing an additional clarifier. 2. Installing gutters on the WPWTP building and snow guards on the WPWTP and Recycle Pump Station buildings. 3. Evaluating and potentially lining the significantly corroded drainpipe near the chemical dosing pumps.

Installing an isolation valve upstream of the High Service BPS. It should be noted that the WPWTP backwash recovery system is not designed to accommodate 18 MGD without an additional clarifier. Increasing plant capacity to 18 MGD without installing the additional clarifier will result in increased flow to the sewer beyond what was intended as part of the WPWTP Phase 1 improvements. This information was provided to the City during the scoping meeting and is repeated here for reference. As part of the scoping meeting, the City identified a number of necessary improvements that currently cannot be accommodated within the budget for Phase s 3 and 4. As such, the following necessary improvements are outside the scope of Phases 3 and 4 and will not be designed as part of this project without an amendment: • Installing a polymer building to thicken the backwash recovery system’s solids waste stream. • Installing additional drying bed capacity. • Installing a permanent means of dewatering the clarifier(s). • Demolishing/salvaging the existing Zone 1 finished water pumps and associated mechanical components within the WPWTP. • Installing roll-up doors for chemical tank replacement in the clean-in-place area. • Installing a storage building. • Installing a locker room. • Installing an additional bathroom. • Installing additional Intake Pump Station generator capacity. • Replacing chain link fencing with anti-climb mesh. This Scope of Work presents the design and permitting tasks for the Phases 3 and 4 Improvements as follows: • Task 1 – Project Management • Task 2 – Preliminary Design • Task 3 – Bid-Ready Design • Task 4 – Permitting Future tasks include the following: • Task 5 – Services During Bidding • Task 6 – Services During Construction City of Pasco Exhibit A WPWTP 18 MGD Expansion – Phases 3 and 4 Design Scope of Work 4 4/14/2025 9:04 AM J:\Data\PSC\25-0072\00 Contract\PSA_SOW_WPWTP Phases 3 and 4.docx General Assumptions The following assumptions were made when preparing this Scope of Work: • The City will provide access to the hard copy data, plans, manuals, etc. required for this project.

Consequently, it is assumed the 2021 approvals cover the Phases 3 and 4 improvements proposed now such that a new SEPA and Special Permit land use approvals are not included in this Scope of Work. It will be necessary to discuss and confirm this assumption with City Planning staff. If required, preparation of new land use permit documents for the Phases 3 and 4 improvements could warrant an amendment to this Scope of Work. Prepare SSDP Application and Submit: Prepare a preliminary SSDP application, including a Joint Aquatic Resources Permit Application (JARPA), project and code compliance narrative, and shoreline site plans for City project staff review. Finalize the SSDP application based on City staff comments, and submit to City Planning staff for review, public noticing, and decision components. Conservatively, it is assumed that an SSDP will be for the proposed Intake Pump Station improvements near the Columbia River; however, confirmation of applicability will be requested during the Pre-Application meeting in subtask 4.3. Coordinate with DOH for Environmental and Cultural Review: Submit proof of SEPA review and compliance to DOH for Drinking Water State Revolving Fund (DWSRF) funding requirements. Prepare a preliminary EZ-1 form, specific to Phases 3 and 4 of this project, together with the prior cultural resources compliance documents prepared for the WPWTP Expansion in 2021 and submit to the City and DOH for Executive Order (EO) 21-02 consultation with the Washington State Department of Archaeology and Historic Preservation (DAHP). Facilitate DOH reviews and DAHP consultation. Prepare an Inadvertent Discovery Plan (IDP) for the project to facilitate construction improvements and DOH cultural approval. It is assumed that SEPA and cultural resources documentation prepared in 2021 cover all phases of the WPWTP Expansion project and consequently, new SEPA or cultural resources documents will not be required. Conservatively, RH2 has included this subtask to facilitate DOH approval for DWSRF funding. A nominal fee for cultural resources support from Cultural Resources Consultants, LLC, (CRC) has been included; however, the effort included in this subtask may require an amendment to this Scope of Work pending coordination with DOH and DAHP. Prepare and Submit City Building Permit: Prepare an application for City Building Permit utilizing the 90-percent design documents prepared in Task 3. Develop energy code and structural calculations to accompany the Building Permit application . Submit the Building Permit application package to the City’s Building Division. Provide Permit Coordination and Support: Support the City with permit compliance and facilitate approvals. This subtask includes up to twenty (20) hours of RH2 staff time to assist the City with permit compliance, reviews, and responding to comments, as requested. Assumptions: • The City will pay all permit fees and be the applicant for permit applications. • Acceptance of permit submittals is beyond the control of RH2 and the City, and no date is warranted or implied for agency response or acceptance.
