Mr. Chaun Benjamin

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• As access to public records and other historical documents is a cornerstone of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.

Mayor Brent Gerry, Committee Chairman Mayor Saul Martinez, Committee Vice-Chairman

AGENDA REPORT
FOR: City Council May 18, 2026
TO: Harold Stewart, City Manager City Council Workshop
Meeting: 5/26/26
FROM: Richa Sigdel, Deputy City Manager
City Manager
SUBJECT: Revision to Water Rights for Commercial and Industrial Irrigation
Purposes (10 minute staff presentation)
I. 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.

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.

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

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.

IV. 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.

Page 67 of 115
together Amendment 6 to continue work on the Butterfield WTP Improvements
project. 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

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.

2. Early Works Design Phase Modifications
2.1 RWPS Driveway Stabilization (Overall Task 8E)
Following the 30% Design Workshop and site visit in June 2025, it was identified that the existing ecology
blocks lining the sides of the driveway have started to erode away. Following the workshop, Jacobs
completed an alternatives evaluation to look at short-term and long-term options to stabilize the driveway
and provide support to the security fence installation along the driveway. 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.

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.
Consultant will submit electronically stamped 100-percent-complete contract documents submittal in
Unlocked PDF and CAD format for use by the City for bidding the construction contract. PDF drawings will be
half-size, 11”x17”. A total of 73 drawings will be included in the contract set as shown in the table below.

3. Pilot Study (Overall Task 15)
The Washington Department of Health (DOH) requires pilot testing to design new filters at loading rates
greater than 6 gallons per minute per square feet (gpm/sf). Filters designed with higher loadings rates
reduce overall footprint and construction costs, as more flow can be pushed through a filter. The pilot study
will include ozonation, rapid mix, coagulation/flocculation, and filtration treatment processes to mimic the
new process. The results of the pilot study will be used to establish ozone demand/decay for ozone system
design criteria, evaluate optimal coagulant dose for chemical building sizing, confirm a shortened
flocculation hydraulic residence time (HRT), and confirm an increased filter loading rate (FLR) to reduce
construction costs. The results will also inform chlorine demand post-treatment for on-site hypochlorite
generation sizing and confirm disinfection byproduct (DBP) formation potential.
The pilot study will be split into three tasks:
· Planning and procurement
· Operation
· Data analysis and reporting
3.1 Pilot Test Planning
Consultant will develop a pilot test plan for the new Butterfield WTP, including the following information:

· Purpose and goals of the pilot testing
· Duration of pilot testing and activities to be completed
· Data to be collected
· Analysis to be performed
· Intended use of data and expected conclusions.
As part of the development of the pilot test plan, Consultant will coordinate a pilot test plan review meeting
with Consultant, DOH, and the City to solicit DOH’s input on the pilot study plan and establish requirements
of pilot testing. Consultant will respond to additional DOH requests as a result of the pilot test plan review
meeting.
Consultant will lead the procurement of pilot equipment, including the following tasks:
· Develop bid documents and specifications for pilot installation
· Define specific features of pilot equipment to be procured
· Establish connection locations and design connecting pipe systems
· Determine representative sample locations and select sample pumps
· Evaluate hydraulics of pilot system
· Prepare process schematics showing proposed installation configuration of pilot system and
installation diagrams showing proposed equipment locations and tie-in points
Consultant will prepare data collection forms that will be used to record system status, maintenance
information, and operations and water quality data.
Consultant will rent the pilot unit for the entire test duration. The pilot system supplier, Intuitech, will
fabricate the pilot enclosure and treatment process skids, and transport them onsite.
Consultant will prepare bid documents for the installation of the pilot enclosure within the fenced area of
the drying beds adjacent to the permanganate Conex. The City will be responsible for providing a Contractor
for installation of the pilot plant in the fenced area around the drying beds. Installation of the system by City
Contractor includes but not limited to placement of a gravel pad, rigging the pilot enclosure on the gravel
pad from delivery truck with a crane, piping installation to convey raw water from permanganate Conex to
the pilot enclosure, and drain piping installation for the pilot discharge to drying beds outlet structure, and

· Pilot test system will include ozonation, flocculation, and filtration.
· Additional equipment purchased for pilot testing includes Chemtrac LCA5, a jar tester, a UVT
analyzer, a DR900, and a pH probe.
3.2 Pilot Test Operation
Consultant will provide and operate the pilot system over four quarters, including the following tasks:
· Determine initial coagulant and polymer doses using Chemtrac LCA-5 Laboratory Charge Analyzer.
· Perform routine checks of the pilot system.
· Perform regular and emergency maintenance. Note that more complicated maintenance activities
(such as broken pipes, pump replacements, etc.) may require support from the City.
· Collect samples for water quality analysis.
· Routinely calibrate instruments.
· Collect and record data.
· Compile filter run reports.
The pilot plant will consist of ozonation, flocculation, and filtration skids housed inside of a custom
enclosure. The pilot plant enclosure will be located near the drying beds. Installation of the pilot plant will
require a contractor for placement of a gravel pad, removal of the pilot enclosure from the delivery truck
and placement of the enclosure on the gravel pad with a crane, pump and piping installation to convey raw
water to the pilot and drain out pilot treated water, and electrical connections.
Operation of the pilot system will be six weeks at a time, depending on the season, for a total of 24 weeks. In
addition to the pilot skid, a climate-controlled trailer and portable toilet will be provided for pilot staff.
Electricity, chemicals, and potable water required for piloting will be provided by the City.
Assumptions:
· Portable toilet will be provided for pilot staff by City.

pilot system when Consultant is not on site, including weekly inspections when the pilot is offline
between quarterly testing periods.
3.3 Pilot Test Data Analysis and Reporting
Consultant will analyze all data that is collected during pilot test operation; figures and tables will be
prepared for use in the Pilot Report. Draft and final versions of the Pilot Report will be prepared for
submission to DOH. The Pilot Report will include the following:
· Purpose of the pilot test.
· Test procedure and setup summary.
· Description of and reasons for variations from the Pilot Test Plan.
· Summary of data collected during pilot testing.
· Results and conclusions gathered from pilot testing.
· Recommendations for water treatment design criteria.

· Pilot Report, Draft and Final
4. Revised Butterfield WTP Implementation Plan for
Greenfield Site (Overall Task 2.7)
4.1 Treatment Process Confirmation Workshop
Consultant will evaluate and update the proposed treatment scheme using the last five years of water
quality data. Consultant will prepare a workshop to reach consensus with City staff on treatment objectives
and resiliency criteria. Consultant will identify alternative treatment schemes and potential for project cost
savings. The following topics will be discussed:
· Updated raw water quality data.
· Evaluate the need for ozonation.
· Disinfectant alternatives as greenfield site will provide more flexibility for phasing.
· Finished water storage.
· Site layout options for greenfield site.

14
Deliverables:
· Workshop presentation and minutes documenting treatment scheme decisions.
4.2 Revised Site Plan
The previous site plan developed for the new Butterfield WTP was based on new facilities and treatment
processes being constructed on the existing Butterfield WTP site. Consultant will develop three preliminary
site plans for a greenfield WTP constructed in the empty plot of land to the east of the existing solids drying
beds. Prior to development of site plans, Consultant will verify previously established design criteria
associated with ozonation and disinfection.
Consultant will schedule a project definition meeting with the City to discuss the revised site plan
alternatives and establish agreement on the preferred site plan alternative. Consultant will provide meeting
minutes following review meeting. Decisions made during the project definition meeting will be
incorporated in the revised Implementation Plan.
Assumptions:
· Site plan development to start after treatment process confirmation workshop and decisions.
Deliverables:
· Workshop presentation and minutes documenting revised site plan decisions.
4.3 Revised Implementation Plan
The previous Implementation Plan developed for the new Butterfield WTP was based on new facilities and
treatment processes being constructed on the existing Butterfield WTP site, which necessitated phased
construction to appropriately sequence construction and demolition efforts. A Class 5 (AACE International)
cost estimate will be developed, based on the proposed site plan and treatment process. Consultant will
revise the Implementation Plan, accounting for changes to site location, project schedule and phasing
needs, cost estimate, and funding.
Consultant will provide City with a draft revised implementation plan. City will provide review comments in a
Bluebeam Revu Studio Session coordinated by Consultant. City will internally reconcile 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 final revised implementation plan accordingly.
Assumptions:
· Design treatment capacity remains unchanged. Space for future expansion will be considered for
site plan development, but not cost estimated.
· Ozone and direct filtration will still be utilized and design criteria associated with flocculation and
filtration remain unchanged.
Deliverables:
· Draft and final version of the revised Implementation Plan.

4.4 Revised Hydraulic Profile
Consultant will conduct a hydraulics evaluation to confirm impact of building on the greenfield site on the
raw water pump station capacity. The evaluation will include whether the existing pumps can achieve the
firm capacity of 30 mgd at the greenfield site using the existing design condition of the raw water pumps.
This study will utilize the pump hydraulic model built as part of the early works design. This study will
evaluate the need for the City to upgrade pumps 6 and 7 under Early Works to achieve the higher total
dynamic head (TDH) that is needed to each convey 10 mgd to the existing Butterfield WTP, which has a
grade elevation that is about 14-feet higher than the greenfield site. Pump replacement recommendation
will include consideration of modernization and maintenance schedule on aging infrastructure.
Deliverables
· Revisions to the Raw Water Pump Station Capacity and Hydraulics Evaluation Technical Memo
prepared under Early Works design.

IV. 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.

Scope of Work
Amendment No. 9
City of Pasco
Process Water Reuse Facility Improvements
Winter Storage
April 2026
Background
The City of Pasco (City) has requested that RH2 Engineering, Inc., (RH2) perform additional tasks
beyond the original scope of work for services during construction. Additional on-site observation
time was required to support project closeout and confirm that the system is functioning as intended.
This effort has included multiple return visits to address evolving punch list items identified during
final inspections, many of which required review of corrective actions, coordination with the
contractor, and documentation for acceptance. Project completion is anticipated for June 1, 2026.
Furthermore, installation of a reticulation line as part of Process Water Reuse Facility Pretreatment
Improvements Phase 2: Winter Storage enabled the irrigation pump station (IPS) wet well to be
drained, allowing RH2 to enter the structure and perform a detailed condition assessment to
evaluate potential corrosion associated with sodium hypochlorite exposure and to develop
appropriate replacement recommendations.
Task 8 – Services During Construction (Regular)
Objective: Provide additional construction-phase services to support project closeout and provide
additional on-site observation of corrosion-related issues at the IPS for reliable system performance
and long-term integrity.
Approach:
Provide additional on-site observation and construction-phase services from January 1, 2026,
through June 1, 2026, to support project closeout, including addressing civil and mechanical
punchlist items, reviewing corrective actions, coordinating with the contractor, and
supporting system testing. CSNW will support this effort by performing these same tasks for
electrical and control items.
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.
Provide the updated technical memorandum to the City for review and comment and finalize
the amended technical memorandum.
