Process Water Reuse Facility Engineering Report Update
February 2023
Background
An Engineering Report (ER) for the City of Pasco's (City) Process Water Reuse Facility (PWRF)
improvements was completed by RH2 Engineering, Inc., (RH2) and Valley Science and Engineering
(Valley) and submitted to the Washington State Department of Ecology (Ecology) in August 2022.
Ecology reviewed the engineering report and responded in November 2022 with comments that
must be addressed by RH2 and Valley prior to final ER approval. These comments will require more
correspondence with Ecology and more extensive edits to the ER than initially anticipated.
Additionally, processors requested additional analysis of potential scenarios that could reduce
improvement costs.
This Scope of Work will amend the original PWRF Engineering Report Update contract by adding
subtasks to the original Tasks 5 and 7.
Task 5 — Prepare Engineering Report — Additional Analysis
Objective: Update Task 5 to include subtasks associated with additional analysis requested by the
processors.
Approach:
5.10 Evaluate three (3) additional scenarios, including the following:
• The proposed Revolving Algal Biofilm is eliminated from the PWRF pretreatment system and
the land treatment system (LTS) is expanded. Recommend the required LTS acreage.
• The proposed low -rate anaerobic digesters capacity is reduced by half. Recommend the
required LTS acreage and provide a qualitative description of potential effects on the LTS.
• Pretreatment is eliminated at the PWRF and individual processors provide their own
pretreatment. Recommend processor permit limits for 5-day biochemical oxygen demand,
total nitrogen, total suspended solids, and fixed dissolved solids.
5.11 Summarize the scenarios in an email to the City.
5.12 Attend one (1) virtual meeting with the processors to assist in explaining the results of the
analysis.
RH2 Deliverables:
• Summary analysis of each scenario in an email.
• Attendance at one (1) virtual meeting with the processors.

Task 7 — Agency Review Revisions — Additional Agency Correspondence
Objective: Update Task 7 to include assistance with additional agency revisions.
Approach:
7.5 Correspond with Ecology and attend two (2) additional virtual meetings to discuss ER
comments.
7.6 Coordinate with Valley to incorporate required revisions to the ER and provide to the City for
final review and Ecology submittal.
7.7 Respond to one (1) additional round of comments/questions from Ecology, if needed.
Provided by City:
• Burnham LLC's revisions to the ER.
RIi2 Deliverables:
• Attendance at two (2) additional virtual meetings with Ecology.
• ER for submittal to Ecology in electronic PDF.
Project Schedule
A matrix of responses to Ecology comments was provided to Ecology in January 2023. Ecology's
response to these comments is anticipated in mid- to late February 2023.
