The Tri-Cities National Park Committee (TCNPC) is a regional leadership and advocacy group that serves as a central point of coordination between the community and federal partners. • Acts as a key liaison to the National Park Service (NPS) and Department of Energy (DOE). • Provides advocacy, alignment, and local leadership to ensure the success of Manhattan Project National Historical Park. • Convened by Visit Tri-Cities, the region’s destination marketing organization. How Was It Formed? • The TCNPC began meeting in early 2015, alongside the establishment of the Manhattan Project National Historical Park. • Formed through a collaborative local effort, led by: o by Steve Young (former Mayor of Kennewick), Gary Petersen with TRIDEC, and the Mayors of Pasco, Richland, and West Richland. • Purpose: The Committee formed to provide a point of contact for the National Park Service and the Department of Energy as well as to offer assistance and advocacy to ensure that the Manhattan Project National Historical Park is a great success. Who is at the Table? A broad coalition representing government, tourism, history, and economic development. The TCNPC meets on a quarterly basis and has historically been comprised of: • Four City Mayors (Kennewick, Pasco, Richland and West Richland) • Benton and Franklin Counties • Port of Benton • B Reactor Museum Association • TRIDEC • Visit Tri-Cities • WSU Tri-Cities Hanford History Project • Hanford Communities • REACH Museum • Richland Public Library Representation from: • DOE + NPS • Congressional Delegation Staff: • Senator Cantwell, Senator Murray, and Representative Newhouse Page 15 of 115 pg. 2 Key Accomplishments • Letter supporting the National Archives and Record Administration’s (NARA) building in Seattle from being sold. • Submitted Appropriations Request to Senator Cantwell and Senator Murray to fund critical work to preserve the B Reactor including the current roof project. • Submitted an application for the NPS American World War II Heritage City Designation. The Tri-Cities was designated a Heritage City in late 2022. Only one city per state is awarded this recognition. • Visit Tri-Cities continues work on a new webpage to highlight and celebrate the Tri-Cities’ designation as an American World War II Heritage City. • The new site will connect visitors and residents to locations throughout the Tri- Cities through window clings and use of QR codes. • Grant funding from the National WWII Museum in Louisiana and funds designated by Visit Tri-Cities, are supporting the creation and installation of signage throughout the community to help raise awareness of the designation and further celebrate this important part of our region’s history. Goals Moving Forward (2026 & Beyond) The committee is focused on long-term growth and preservation. • B Reactor Grand Re-Opening (target: 2028) • Promote and leverage WWII Heritage City designation • Rivers, Trails & Conservation Assistance (RTCA) Program • Community Visioning and Analysis of STEM Assets • Preservation of Pre-Manhattan Assets • Park Boundary Expansion Why It Matters The Tri-Cities sits at the center of a nationally significant story. Through coordinated leadership and advocacy, the TCNPC helps: • Strengthen tourism and economic development • Preserve globally important history • Position the Tri-Cities as a nationally and internationally recognized heritage destination The Tri-Cities National Park Committee is administered by Visit Tri-Cities.

Page 16 of 115 TRI-CITIES NATIONAL PARK COMMITTEE B REACTOR MUSEUM ASSOCIATION February 8, 2021 Mr. Chaun Benjamin Government Services Administration Regional Headquarters Building 400 15th Street SW Auburn, WA 98001 Dear Mr. Benjamin: RE: Support of Washington State Attorney General Save the State of Washington Archives The Tri-Cities Manhattan Project National Historical Park Committee fully supports the twenty- nine federally recognized tribes, tribal communities, the State of Oregon, and the nine community organizations who have partnered with the Washington State Attorney General’s office lawsuit to save the National Archives and Record Administration’s (NARA) building in Seattle from being sold. In brief, the case for preserving the National Archive in Seattle boils down to three essential considerations: ancestry, accessibility, and accountability. • The Seattle facility houses original and important federal records for four states— Washington, Oregon, Idaho, and Alaska—and our region’s first people, dating back more than 150 years. These records represent the history of the Pacific Northwest, our history, and they belong here with us. • According to NARA, just “.001% of the facility’s 56,000 cubic feet of records are digitized and available online.” With so few of its holdings available digitally, removal of physical archival records to Riverside, CA and Kansas City, MO would effectively eliminate access to these resources for whom they are most valuable: researchers, historians, and individuals seeking greater understanding of our region’s history and heritage. • As access to public records and other historical documents is a cornerstone of transparency and accountability, restricting availability to these archival materials would most certainly serve to further erode public trust in state and federal leadership. The archive is home to many of the most important records relating to the history of the Manhattan Project and its many legacies. For this reason, keeping the Seattle facility is of particular importance to this community and to the Manhattan Project National Historical Park, Hanford Unit, which works closely with this committee. These records are instrumental to the National Park Service’s efforts to tell the whole story of what was arguably the most important event of the last century, not only for our community, but for our country and for the entire world. In addition, they remain a vital resource for scholars, historians, writers, and public policy experts interested in better understanding how government, scientists, academics, and industry came together to launch the nuclear age that we are living in today. The Hanford History Project is a partnership between the U.S. Department of Energy and Washington State University (WSU) that is responsible for archiving and digitizing Manhattan Project History. Loss of these records during relocation is of great concern and we request that at a minimum they be retained for digitization. The Tri-Cities National Park Committee is made up to the Tri-Cities cities of Kennewick, Pasco, West Richland and Richland, Benton County, Visit Tri-Cities, TRIDEC, Hanford History Project, B Reactor Museum Association, and the Port of Benton. We get monthly updates from U.S. Department of Energy on facilities and tours and from National Park Page 17 of 115 Service on education and interpretation. Interest in visiting Hanford’s national park facilities continues to grow due to the significance of the Manhattan Project and the Cold War. Prior to COVID, the Tri- Cities community hosted about 15,000 national park visitors to Hanford each year, and WSU held national seminars and ongoing education related to the archives. These activities help the public understand not only Hanford’s history, but the legacy waste resulting from Hanford’s defense role, and the importance of cleaning up the Hanford Site. For all these reasons, we strongly support the Attorney General’s coalition to save the State of Washington archives and agree that the federal government’s consultation process was not followed, and this transaction should not proceed without full consultation with all tribal nations, local communities and families who desire access to their historical heritage. In addition, we urge the State of Washington to view this proposed action as causing a loss of ongoing academic scholarship on Hanford, and a loss of potential economic activity associated with bringing interested parties from around the world to Washington State to learn about the Manhattan Project.

ATTACHMENT(S): II. ACTION REQUESTED OF COUNCIL / STAFF RECOMMENDATIONS: Discussion III. FISCAL IMPACT: IV. HISTORY AND FACTS BRIEF: Background The City of Pasco collects water rights or fees in lieu of water rights from all applicants for new water service connections under PMC 13.15.030. The current code requires irrigation water rights dedication sufficient to cover 50 percent of the lot or parcel to be served, using a residential-equivalent formula of 3.5 acre-feet per year per irrigable acre. Applicants without appurtenant water rights pay an in-lieu acquisition fee, which was updated to $4,150 per acre-foot. For a standard 6,000 sf lot, the cost of water rights for potable water is $1,245 and irrigation water is $1,000; total water rights in-lieu fees being $2,245. Industrial and commercial developers have raised consistent concerns that the residential-equivalent irrigation actual their significantly formula overstates demand, for the following reasons:  Industrial and commercial sites typically have high impervious lot coverage, paved yards, building footprints, and hardscape, leaving a small fraction of the parcel as irrigable area.  Many industrial sites use gravel, rock, or decorative aggregate instead of living vegetation, resulting in near-zero irrigation demand.  Xeriscape or low-water landscaping is common in commercial settings and consumes a fraction of the water assumed under the standard formula. Page 42 of 115 To address the treatment of industrial and commercial properties at the permitting stage, staff is recommending the following:  Create two elective alternative tracks for industrial and commercial applicants in lieu of the standard formula. o Track 1 - Site Plan-Based Metered Dedication: Water rights dedication calculated on actual net irrigable landscaped area from acre 3.5 the at standard site approved the plan, feet/year/acre rate. o Track 2 - Xeriscape Reduced Dedication: A discounted dedication rate of 1.5 acre feet/year/acre rate.  Require irrigation metering on all properties utilizing either alternative track.  Memorialize the irrigation baseline and overage obligations requiring a recorded deed restriction or conservation easement or service contracts Impact (Other than fiscal) If approved, this action will have the following real and potential impacts:  Removes an identified barrier to industrial and commercial development in rights with dedication water requirement aligning by the Pasco verifiable actual irrigation demand rather than a conservative residential- equivalent formula.  Supports City Council's economic development goals by reducing upfront development costs for qualifying non-residential projects.  Incentivizes water-efficient landscaping through the xeriscape rate reduction, advancing broader water conservation objectives.  Requires investment in irrigation metering infrastructure and monitoring capacity. Staff will need resources to track metered baselines and enforce property restriction obligations. This need should be addressed in the 2027-2028 budget cycle if Council approves.  Potential for compliance disputes if property owners later alter landscaping in ways that deviate from the approved site plan. The deed restriction, service contract or conservation easements the proposed program are designed to address this risk; however, enforcement is significantly more difficult in these scenarios. V. DISCUSSION: Recommendations Staff recommends the following: 1. Establish a site plan-based metered irrigation water rights dedication methodology for industrial and commercial development (Track 1); 2. Establish a xeriscape reduced dedication rate for certified low-water landscaping with required metering (Track 2); 3. Require recorded deed restrictions or conservation easement or service contracts on all properties, memorializing the irrigation baseline and overage obligations; Page 43 of 115 4. Establish a baseline requiring the property owner to transfer additional water rights or pay the in-lieu fee when metered use exceeds 120% of the dedicated baseline for two consecutive years, or when irrigated area is expanded or xeriscape is converted; and Constraints (Time or Other Considerations) 1. Timely implementation will allow for lower development costs to commercial and industrial customers. Next Steps If the recommendation is approved, staff will: 1. Prepare an ordinance that incorporates Council direction. 2. Conduct a public comment period consistent with applicable state law requirements . 3. Develop, in coordination with the City Attorney: deed restriction form or conservation easement or service contracts and recording procedures; xeriscape certification standards and approved certifier criteria; landscape plan submission requirements for Track 1 and Track 2 applications. 4. Procure and configure metering equipment for new commercial and industrial irrigation services; establish a baseline monitoring protocol within Public Works. Alternatives 1. Take no action. Continue applying the residential-equivalent irrigation formula to all development types. This maintains code consistency but perpetuates the identified barrier to industrial and commercial development and does not respond to ongoing developer feedback. 2. Adopt Track 1 (site plan-based metered dedication) only, without the Track 2 xeriscape reduction. Simpler to administer but foregoes the conservation incentive and does not address concerns from developers with primarily hardscape or gravel sites. Page 44 of 115 Water Rights Reform for Commercial & Industrial Development Proposed Revision to PMC 13.15.030 —Irrigation Water Rights Dedication Pa g e 4 5 o f 1 1 5 THE PROBLEM The current formula overstates irrigation demand for commercial and industrial sites. High Impervious Coverage Industrial sites have large building footprints, paved yards & hardscape —very little irrigable area. Zero-Irrigation Surfaces Many sites use gravel, rock, or decorative aggregate with near-zero actual irrigation demand. Xeriscape Is Common Low-water landscaping is standard in commercial settings —fraction of residential water use. Current formula: 3.5 AF/year/acre applied to 50% of total lot —regardless of actual landscape coverage. Pa g e 4 6 o f 1 1 5 PROPOSED SOLUTION Two elective alternative tracks for commercial & industrial applicants TRACK 1 Site Plan-Based Metered Dedication Water rights calculated on actual net irrigable landscaped area from the approved site plan —at the standard 3.5 AF/year/acre rate. Irrigation metering required Deed restriction /conservation easement/service contract recorded TRACK 2 Xeriscape Reduced Dedication Discounted rate of 1.5 AF/year/acre for certified low-water / xeriscape landscaping. Irrigation metering required Xeriscape certification required Deed restriction / conservation easement/service contract recorded OR Pa g e 4 7 o f 1 1 5 COMPLIANCE & PROTECTIONS 01 Irrigation Metering Required All properties on either track must install dedicated irrigation meters to enable ongoing consumption monitoring. 02 Recorded Restriction Irrigation baseline and overage obligations memorialized via deed restriction, conservation easement, or service contract. 03 Overage Trigger —120% Rule If metered use exceeds 120% of dedicated baseline for two consecutive years, owner must transfer additional water rights or pay the in-lieu fee. 04 Land Use Change Triggers Expanding irrigated area or converting xeriscape to conventional landscaping immediately triggers additional dedication or payment. Pa g e 4 8 o f 1 1 5 IMPACTS & BENEFITS BENEFITS •Removes identified barrier to industrial & commercial development in Pasco •Supports Council's economic development goals by reducing upfront costs •Incentivizes water-efficient landscaping and advances conservation objectives CONSIDERATIONS •Requires irrigation metering infrastructure —budget need in 2027-28 cycle •Increased administrative capacity needed to track baselines and enforce restrictions •Compliance disputes possible if owners later alter landscaping from approved plan •Deed restriction / easement enforcement more complex than upfront collection Pa g e 4 9 o f 1 1 5 STAFF RECOMMENDATION 1.Establish Track 1 —site plan-based metered irrigation water rights dedication for commercial & industrial development 2.Establish Track 2 —xeriscape reduced dedication rate (1.5 AF/year/acre) for certified low-water landscaping with required metering 3.Require recorded deed restrictions / conservation easements on all Track 1 and Track 2 properties 4.Establish 120% metered-use overage threshold triggering additional dedication or in-lieu fee payment NEXT STEPS (if approved) •Draft ordinance incorporating Council direction → Conduct public outreach → Attorney review •Develop property restriction forms, xeriscape certification standards, and landscape plan submission requirements •Procure metering equipment and establish baseline monitoring protocol within Public Works Pa g e 5 0 o f 1 1 5 AGENDA REPORT FOR: City Council April 29, 2026 TO: Harold Stewart, City Manager City Council Workshop Meeting: 5/26/26 FROM: Maria Serra, Director Public Works SUBJECT: Resolution - Professional Services Agreement Amendment No. 4 with RH2 Engineering, Inc. for Design Services for the Process Water Reuse Facility Phase 4 Irrigation System Farm Upgrades Project (5 minute staff presentation) I.

HISTORY AND FACTS BRIEF: Background: The Process Water Reuse Facility (PWRF) Irrigation System Farm Upgrades Project planned of series the current phase fourth the encompasses of improvements and modifications to the PWRF. This project (informally referred to as PWRF Improvements Phase 4) will replace existing irrigation system components nearing their end-of-life, construct new irrigation assets to convey the pretreated process water to the City-owned land application farm circles, and extend the system to newly created land application areas from recently purchased parcels. The City secured the professional services of RH2 to provide holistic planning, design and permitting support services for the proposed improvements to implement the land treatment system expansion consistent with the “Process Water Reuse Facility Engineering Report”approved by the State of Washington Department of Ecology on April 12, 2023. Amendment No. 1 to the PSA addressed various evolving project needs. These included added Field Investigations and background review, 60 and 90 percent Irrigation Pump Station (IPS) Improvements Designs, and Bid ready plans and specifications. Amendment No. 2 to the PSA addressed various evolving project needs. These included additional analysis and design for pipelines and IPS (Irrigation Pump Station) design adjustments to reflect the revised site work, additional distribution system improvements, and updated controls for the system. The majority consultant during services for amendment the of provides construction, to assist with engineering services through the duration of project and assistance during project closeout. Amendment No. 3 to the PSA addressed the needs for construction and finalization of the bid documents with the changes to Circles 14 and 16. As construction needs and further coordination changes/submittals/RFIs for the project were further refined, the scope of the project was subject to revisions and adjustments. The proposed amendment will provide the additional construction support that is needed for coordinating with the County and the Contractor. Impact: The proposed upgrades will provide the distribution and irrigation infrastructure needed to increase PWRF operations and meet the State Waste Discharge Permit for the next season. The upgrades needed and the addition of two Page 52 of 115 irrigation fields allows PWRF to not only meet the State Waste Discharge Permit but also allow for a more robust irrigation for the added processor capacity to PWRF. V. DISCUSSION: Recommendation: Staff has reviewed and recommends approval of Amendment No. 4 to the PSA with RH2 Engineering in the amount of $54,303.00 for the PWRF - Phase 4 Irrigation System Farm Upgrades project. The proposed Amendment No. 4 to RH2 Professional services agreement addresses the additional work needed for construction completion. The proposed amendment will provide the additional construction support that is needed for coordinating with the County and the Contractor. The amendment also adds additional consultant services during construction, as there have been high amount of submittals, RFIs, and construction coordination. Constraints: Construction of this project has been planned to minimize interruptions and/or impacts to PWRF Farm Operations and must be completed on schedule. Projected 2026 flows at PWRF will necessitate the additional land treatment area. Next Steps: Provided the Council approves the amendment, staff will work with the consultant to complete all necessary contractual documentation in the upcoming weeks. Alternatives:  Council may choose to reject the amendment. This is not recommended since the additional construction support is needed to ensure construction deadlines are met. The timeline associated with this alternative action would hinder expansion of the land treatment system and therefore fail to comply with the parameters established for the facility under the State Waste Discharge Permit for PWRF; likely resulting in violation of the permit and/or limiting industries from sending flows to the facility which has, in turn, a negative economic impact to the industries and the utility.

All work under Amendment 6 and construction of the Raw Water Pump Station and Electrical Improvements project (Early Works Phase) are anticipated to use the funds available from the $14.727M DWSRF loan. Going forward, additional low interest loan/grant opportunities will be pursued to support the future construction phases of this project. Funding for Amendment Nos. 1-5 of the project are paid for by a low-interest loan through the Washington State Department of Health (DOH) Drinking Water State Revolving Fund (DWSRF) for preconstruction activities, awarded in the amount of $510,000. Additional funding is provided by a second low- interest loan through the Public Works Board Preconstruction Program, awarded in the amount of $1,000,000. Remaining funding is allocated from the Utility Fund (Water Fund 411). IV. HISTORY AND FACTS BRIEF: Background: On January 5, 2024, the city entered into a Professional Services Agreement (PSA) with Jacobs for the Butterfield WTP electrical system upgrade predesign services. Overall tasks included the following:  Condition assessment of the existing electrical service and backup power generator, the intake screens, raw water pump and ancillary chemical feed systems.  30% preliminary design package for the electrical system upgrades including a new electrical building and new electrical equipment and standby power to supply existing and future facilities.  A project definition evaluation to identify treatment process objectives.  Development of a project implementation and phasing approach and preliminary site plan.  Funding strategy assistance to identify potential funding alternatives to design and construct the future improvements. An amendment to the Butterfield WTP Facility Plan issued in 2023 provided additional recommendations for remediation with respect to cyanotoxins and aquatic plant (milfoil) growth present in the Columbia River during the seasonally warmer months. These recommendations led to an alternate sequence of phased replacement of the Butterfield WTP that prioritizes meeting new water quality and facility operational challenges caused by climate change. Several amendments have been executed since the initial PSA. They are described below: Amendment No. 1 scope included completion of construction bid documents previously initiated by in-house City engineering staff for the installation of a Page 68 of 115 precast concrete permanganate injection vault located at the 36-inch raw water inlet piping downstream of the raw water pump station. This work also included relocation of the chemical storage and feed pump system and instrumentation, and installation of pipe tapping saddles, chemical piping, and chemical injection equipment. Amendment No. 1 was approved September 12, 2024, by the City Manager. Amendment No. 2 scope added $1,173,300.00 for 90% design services for the Raw funding Improvements Electrical project, Station Pump Water and application support, and a geotechnical investigation of the existing Butterfield site. Amendment No. 2 was approved by City Council October 28, 2024. Amendment No. 3 was a no cost amendment that shifted funds within the PSA to provide additional design and services during bidding for the Raw Water Permanganate System project and additional geotechnical support due to unforeseen soil conditions at Butterfield WTP. Amendment 3 was approved by the Public Works Director on April 7, 2025. Amendment No. 4 was a no cost amendment that shifted funds within the PSA to provide additional design and construction services for the Raw Water Permanganate System project, as well as additional design scope for the Raw Water Pump Station and Electrical Improvements project, and an evaluation of building a new Butterfield WTP on a greenfield site. Amendment 4 was approved by the Public Works Director on October 30, 2025. Amendment No. 5 was a no cost amendment that shifted funds within the PSA to provide additional design scope for the Raw Water Pump Station and Electrical Improvements project. Scope included evaluations of alternatives for the raw water pump station HVAC system, driveway, and diver access with the proposed installation of a fencing/security system. A utility location with ground penetrating radar (GPR) was also completed. Amendment 5 was approved by the Public Works Director on February 16, 2026. Amendment No. 6 (Proposed) With the recent approval of the $14.727 million dollar loan from the Washington State Department of Health DWSRF program, work on the Butterfield WTP Improvements approval proposed of continue. The ready is project to Amendment 6 will allow for the 100% completion of the Raw Water Pump Station and Electrical Improvements design phase and the completion of pilot testing following and future design planning. The tasks/subtasks will be completed as part of Amendment 6: 1. Station Pump and Electrical Improvements design Raw Water modifications:  90% and 100% design of driveway stabilization at the Raw Water Pump Page 69 of 115 Station.  90% and 100% design of HVAC requirements at the Raw Water Pump Station.  90% and 100% design to include the new transformer and conduit routing through the levee.  Permitting support regarding a United States Army Corps of Engineer's real estate application.  100% complete design of the Raw Water Pump Station and Electrical Improvements project.  Services During Bidding. The Raw Water Pump Station and Electrical Improvements project will address many improvements at the Raw Water Pump Station which is located on the Columbia the and items above the include will Improvements River. replacement of in water screens, pumps, check valves, electrical distribution panels and harmonic filters as well as the installation of pressure indicators, a redundant level indicator, security fencing and cameras and a standby power roll-up connection for the Raw Water Pump Station and Backwash Lift Station. 2. Piloting of proposed water treatment processes  Pilot plan development, design of pilot system, and coordination with the Department of Health (DOH).  Procurement of pilot system.  Pilot installation bid drawings and specifications  Operations of pilot system.  Analysis of pilot data and development of pilot test results report. A pilot test includes a small-scale replica that mimics the treatment process for a large-scale Water Treatment Plant. For this project, a pilot test will be designed and built according to the planned treatment process for the new Butterfield WTP. Pilot testing is required by the DOH to design new filters at loading rates greater than 6 gallons per minute per square foot (GPM/Ft). The pilot study will consist of running all 4 seasons for 4-6 weeks duration each season. 3. Butterfield WTP Implementation Plan modifications for greenfield site  Revised site plan, including a project definition meeting  Revised implementation plan, including an updated cost estimate and funding analysis  Revised hydraulic profile and evaluation of existing and proposed raw water pumps The Butterfield Implementation Plan serves as a big picture of the path forward on the Butterfield WTP Improvements project. Recently, a greenfield location has been chosen to build the new Butterfield WTP plant. The new location is Page 70 of 115 located near the existing drying beds and Raw Water Pump Station (South of the S 12th Ave and W Washington St intersection). Placing a new Butterfield WTP on a greenfield site will allow for the uninterrupted operation of Butterfield while a new plant is being constructed. The existing Implementation plan will need to be revised to reflect the change in location, and to evaluate the existing infrastructure at the raw water pump station. This evaluation will determine if different pumps/materials will be needed due to the change in WTP location. Impact (other than fiscal): This project addresses the replacement of the Butterfield Water Treatment Plant (WTP). The Butterfield WTP has served the City of Pasco since 1946 and is nearing the end of its useful life. Without improvements, the city will risk the safe delivery of treated water to all of its residents. Once complete, Butterfield is anticipated to reliably deliver 30 million gallons of treated water per day to the residents of Pasco. V. DISCUSSION: Recommendation: Staff has negotiated the amendment scope and fee and found it to be reasonable. Staff recommends approval of Amendment No. 6 to the PSA with Jacobs Engineering Group, Inc. in the amount of $2,020,000 for the Butterfield Water Treatment Plant Improvements Project. Constraints: The Butterfield WTP is critical to the overall water system. Its reliability is key for the delivery of treated water to the residents of Pasco. Butterfield WTP is nearing the end of its useful life and is in need of replacement. The proposed improvements the begin will and the plant reliability the extend will of groundwork for the future replacement of the entire WTP. Next Steps: If approved by City Council, Jacobs will complete the design for the Raw Water Pump Station and Electrical Improvements project, as well as begin the pilot testing to Butterfield the revisions treatment and technology for make Implementation Plan, reflecting the greenfield site and funding strategy consistent with approved rates. Construction for the Raw Water Pump Station and Electrical Improvements project is anticipated to begin at the end of 2026. The pilot testing will begin by fall of 2026 and will run until fall of 2027. Alternatives: If Amendment 6 is not approved, the overall replacement project will be postponed and a need to re-evaluate the improvements to the Butterfield WTP project will be necessary. This option accepts increased risk in the potential failure of the plant prior to replacement. Page 71 of 115 Resolution – Amend.

Results and a recommendation were shared with the City at the 60% Design Workshop in September 2025, including driveway stabilization using grade beams and walls along the edge of the driveway to replace the ecology blocks as a bid alternative to the Early Works project. Ground penetrating radar (GPR) was completed in February 2026 to verify the location and depths of the raw water pipes along the driveway. Page 77 of 115 Butterfield WTP Improvements Scope of Work 5 This amendment includes detailed design of the driveway stabilization developing 90% and final (100% complete) design documents consisting of technical specifications and drawings. It includes a 2-day site visit for a civil engineer to verify site conditions for the final design. City will provide review comments for each design milestone in a Bluebeam Revu Studio Session coordinated by Consultant. City will internally adjudicate its review comments to provide clear direction for Consultant. Consultant will provide a written response within the Bluebeam Revu Studio Session to each written review comment provided by City and incorporate the comments into the subsequent design documents accordingly. Assumptions: · Additional works included in this amendment will be bid as part of the Early Works Project construction contract. · Results of GPR utility locate will be used for driveway stabilization design and must be completed prior to finalization the design of the driveway. · Level of effort is based on the addition of two (2) drawings: o Civil Site Plan o Structural Details 2.2 RWPS HVAC Design (Overall Task 8F) During the 60% Design Workshop in September 2025, the City noted that there are issues with control panels overheating in the RWPS due to a lack of ventilation. Two larger pump motors will be designed as part of the raw water pump replacement in Early Works base scope. These larger motors will generate more heat and any existing ventilation issues within the RWPS can worsen. An evaluation of HVAC requirements will be performed as part of Amendment 5. Following this evaluation, the City will decide on an alternative to carry forward to detailed design. Consultant will complete a detailed design of the selected HVAC system by developing 90% and final (100% complete) design documents. The completed design documents will consist of technical specifications and drawings. City will provide review comments for each design milestone in a Bluebeam Revu Studio Session coordinated by Consultant. City will internally adjudicate its review comments to provide clear direction for Consultant. Consultant will provide a written response within the Bluebeam Revu Studio Session to each written review comment provided by City and incorporate the comments into the subsequent design documents accordingly. Assumptions: · Additional works included in this amendment will be bid as part of the Early Works Project construction contract. · Level of effort is based on the addition of specification sections determined once alternative is selected, and three (3) HVAC drawings: o General Sheet Page 78 of 115 Butterfield WTP Improvements Scope of Work 6 o Plan and Air Flow Schematics o Sections and Details 2.3 Transformer and Levee Conduit Design (Overall Task 8G) A National Energy Code (NEC) analysis completed by Jacobs suggests that the RWPS is currently overloaded. During initial coordination with Franklin PUD on the RWPS improvements, PUD indicated that they’re at capacity with existing transformers and a new pad-mounted transformer is required to provide the increased power capacity to the RWPS. Further investigation by Jacobs and the City showed that the existing conduits between the current transformer and RWPS are not large enough for additional lines to be added. A new conduit will need to be routed between the new pad-mounted transformer by PUD to the RWPS. It is assumed that the transformer pad and conduit construction will require USACE, rather than railroad (BNSF) coordination. Coordination with Franklin PUD and USACE regarding the details of transformer placement and permitting/easement requirements for electrical conduit through the existing levee, respectively, will occur as part of Amendment 5. Consultant will complete a detailed design of the project by developing 90% and final (100% complete) design documents. The completed design documents will consist of a technical specification for the transformer and associated drawings. City will provide review comments for each design milestone in a Bluebeam Revu Studio Session coordinated by Consultant. City will internally adjudicate its review comments to provide clear direction for Consultant. Consultant will provide a written response within the Bluebeam Revu Studio Session to each written review comment provided by City and incorporate the comments into the subsequent design documents accordingly. Assumptions: · Additional works included in this amendment will be bid as part of the Early Works Project construction contract. · City will coordinate with Franklin PUD on transformer location. · Construction area is within USACE property. No coordination with BNSF is required. · Level of effort is based on the addition of two (2) electrical drawings: o Electrical Site Plan o Site Plan Details 2.4 Early Works Phase Final Design (100% Design) (Overall Task 8) A Management Reserve was established as part of Amendment 2, intended to be used for Early Works Phase final design (100% design). Amendment 6 includes approval for the use of these Management Reserve funds for the Early Works 100% complete submittal. The use of the 100% design budget in management reserve was contingent on receiving construction funding for the Early Works project. In January 2026, the City approved the $14.7M Drinking Water State Revolving Fund (DWSRF) loan to fund the Early Works construction. Consultant will prepare a 100% complete submittal of the design, including front end specifications and an Engineers Opinion of Probable Construction Cost (EOPCC). Consultant will incorporate City’s and agency Page 79 of 115 Butterfield WTP Improvements Scope of Work 7 review comments from the 90% submittal into the 100% complete design submittal. The 100% complete submittal will be used to bid the construction contract. The Draft 100-percent complete design package review comments will be discussed at a subsequent project manager check-in call, as needed. No meetings to review or discuss the Final 100-percent complete design package are planned or budgeted. Design changes that impact the cost estimate are not anticipated after 90% design, but the estimate will be updated based on the 100% design if needed.

HISTORY AND FACTS BRIEF: Page 97 of 115 Background The Process Water Reuse Facility (PWRF) Phase 2 Winter Storage Improvements project began with the City of Pasco entering into a Professional Services Agreement (PSA) with RH2 Engineering, Inc. in August 2021 to design 200 million gallons of winter storage ponds. The scope later expanded to over 300 million gallons to accommodate existing processors' future growth, prompting multiple contract amendments for environmental permitting, land acquisition, agencies. regulatory state and and with coordination federal Amendments 1 through 6 addressed needs ranging from NEPA compliance to dam safety requirements, and extended construction support through 2025. The project is being fully funded through a State Revolving Fund (SRF) low- interest loan administered by the Washington State Department of Ecology and authorized under Resolution No. 4425. As a Designated Equivalency Project (DEP), it is subject to federal requirements for labor documentation, reporting, and complexity project to of layers adding verification, payroll contractor oversight and coordination. Prior amendments to the PSA (1 through 8) addressed various evolving project needs. These included added environmental permitting for land acquisition (Amendment 1), preparation of an Environmental Site Assessment required by the US Bureau of Reclamation (Amendment 2), additional permitting to comply with federal funding and NEPA requirements for an expanded disposal site (Amendment 3), and engineering services to address Dam Safety regulations and coordination with other ongoing construction phases (Amendment 4). Amendments 5 and 6 provided for extended construction support services, contract 6 with compliance, Amendment and administration, regulatory extending RH2's services through the end of 2025 without a change in scope or cost. Amendment 7 includes additional construction administration, onsite inspections, and expanded coordination responsibilities to ensure regulatory compliance. It also provides engineering support for well drilling operations and additional coordination with Burnham accommodating the PRRC startup timeline. Amendment 8 extending RH2's services through the end of 2026 without a change in scope or cost. Impact The proposed amendment addresses multiple concerns that came up during construction, which included multiple return visits to address evolving punchlist items identified during final inspections, many of which required review of corrective actions, coordination with the contractor, and documentation for acceptance. V. DISCUSSION: Recommendation Staff has reviewed and recommends approval of Amendment No. 9 to the PSA with RH2 Engineering in the amount of $74,819.00 for the PWRF - Phase 2 Page 98 of 115 project. The proposed Amendment No. 9 to RH2 Professional services agreement addresses the additional work needed for completion of the construction phase. observation on-site provide and amendment proposed The will construction phase services. And to provide additional condition assessment related to corrosion within the IPS well and prepare an amendment to the IPS Corrosion Investigation Technical Memorandum prepared by RH2. Constraints Construction of this project has been planned to minimize interruptions or impacts to PWRF and needs to keep moving forward. Performing a condition assessment, sodium evaluating potential corrosion associated with hypochlorite exposure, and developing appropriate replacement recommendations has been identified as a current need. Next Steps Provided the Council approves the amendment, staff will work with the consultant to complete all necessary contractual documentation in the upcoming weeks. Alternatives Council may choose to reject the amendment. This is not recommended since the additional construction support is needed to ensure construction meets deadlines.
