Dear Mr. King:

Robertson- Bryan, Inc. ( RBI) has been assisting the City of Lathrop ( City) in preparing to discharge treated effluent from its Consolidated Treatment Facility ( CTF) to the San Joaquin River. In September of this year, RBI expended its funding under its current City contract, which covered river discharge preparation services for the prior 12 months ( 2022 Contract).

This proposal is for RBI services that need to be completed through the end of 2023 to further ready the City for initiation of river discharge ( anticipated for April 2023). These tasks are explained further in the detailed scope of work and budget provided below.

I. SCOPE OF WORK
TASK 1: VEOLIA O& M CONTRACT
Task 1. 1: Contract Negotiations
RBI will assist the City in negotiating and finalizing the operation and maintenance ( O& M) contract with Veolia Water West Operating Services, Inc. ( Veolia) to operate the CTF in compliance with the applicable sections of the National Pollutant Discharge Elimination System ( NPDES) permit and Waste Discharge Requirements/ Master Recycling Permit. RBI prepared the current draft O& M contract between Veolia and the City under our 2022 Contract. RBI will support the City in this effort with meeting attendance and incorporating requested edits to the draft contract. RBI will work with the City so the new contract provides clarity regarding roles and responsibilities for Veolia and the City, and responsibilities for compliance with the applicable sections of the NPDES permit and data gathering to ensure complete reporting consistent with the NPDES permit Monitoring and Reporting Program.

Task 1. 2: Meetings
RBI will attend up to four( 4) virtual meetings with the City and Veolia regarding contract negotiations and revisions.

Lathrop, CA 95330
Subject: Proposal to Provide Professional Services to Assist with Implementing all Requirements of the City of Lathrop Consolidated Treatment Facility NPDES Permit through December 2023
Dear Mr. King:

Robertson- Bryan, Inc. ( RBI) has been assisting the City of Lathrop ( City) in preparing to discharge treated effluent from its Consolidated Treatment Facility ( CTF) to the San Joaquin River. This proposal is for RBI services that need to be completed to maintain compliance with its National Pollutant Discharge Elimination Permit( NPDES) permit through the end of 2023. These tasks are explained further in the detailed scope of work and budget provided below.

I. SCOPE OF WORK
TASK 1: NPDES PERMIT REPORTING
Subtask 1. 1: Routine Self-monitoring Reports ( SMRs)
RBI will assist the City with preparing and reviewing data files and cover letters for routine SMRs, which includes monthly, quarterly, and annual reports. RBI also will assist with preparation and review of the Discharge Monitoring Report( DMR) that is required with each SMR submittal. Both the DMR and SMRs are uploaded to the California lntegrated Water Quality System ( CIWQS) database. RBI will assist the City in preparation of draft SMRs and will review draft SMR and DMR data files to ensure they contain the NPDES permit- required information, the calculated and analytical parameters are accurate, and the contents of the cover letter and any attachments are consistent with the reported data. RBI will work with the City to finalize the SMRs for upload to CIWQS and will coordinate with the City to ensure the SMRs are submitted and certified in CIWQS by the report due date. The City is responsible for conducting the final submittal and certification of SMRs in CIWQS. Hours budgeted are for providing assistance with SMRs/ DMRs for the following submittals. 3100 Zinfandel Drive, Suite 300 Phone 916. 714. 1801

Subtask 1. 2: One- time Reports
RBI will prepare the following one- time reports required by the NPDES permit. While the one report is due February 1, 2024, RBI will need to begin working on it by December 2023, hence its inclusion in this scope of work.

Analytical Methods Report Certification due January l, 2023 Mercury Pollution Prevention Plan due February 1, 2024
TASK 2: COORDINATION AND REVIEW OF CONTRACT LABORATORY TESTING Subtask 2. 1: Whole Effluent Toxicity Testing
RBI will assist the City with scheduling, coordination, and reviewing results of routine, quarterly whole effluent toxicity (WET) testing required by the NPDES permit during Ql—Q4 2023 ( four routine quarterly reports). RBI will advise the City on whether permit-required accelerated testing or a
toxicity reduction evaluation ( TRE) has been triggered. In the event a Michael King Ro' soH BRYA lx
City of Lathrop
SotutlansforProgress
November 7, 2022

TRE is triggered by the routine bioassay results, the City must submit a TRE Action Plan to the Central Valley Water Board within 30 days. Budget is provided for RBI to prepare one ( 1) TRE Action Plan for the City to provide a timely submittal, should a TRE be triggered. RBI will provide a separate scope and budget to provide assistance beyond the hours budgeted herein in the event that additional effort is required to assist implementing routine testing, accelerated testing, or a TRE. We assume that the City will contract laboratory testing services separate from RBI' s contract and that Veolia operations staff will collect the effluent samples used for bioassay testing.

Subtask 2. 2: Effluent and Receiving Water Characterization Monitoring The City is required to conduct four quarters of effluent and receiving water characterization monitoring during Q2 2023—Q1 2024. RBI will coordinate with the City, Veolia, Compliance First, and FGL to ensure that the testing will be completed as required. This scope of work and budget assumes that Veolia or FGL will collect the effluent samples, Compliance First will collect the receiving water samples, and FGL will be responsible for analytical testing.

RBI will review the laboratory reports, coordinate with FGL on any QA/ QC issues, and prepare the data for submittal to CIWQS with the SMRs.

Subtask 2. 3: Pyrethroid Pesticides Monitoring
The City is required to conduct four quarters of effluent and receiving water monitoring for pyrethroid pesticides and acute toxicity using the pyrethroid- sensitive test species, Hyalella aztecca during Q2 2023—Q1 2024. RBI will coordinate with the City, Veolia and FGL to ensure that the testing will be completed as required. This scope of work and budget assumes that Veolia or FGL will collect the effluent samples, Compliance First, LLC will collect the receiving water samples, and McCampbell Analytical will conduct the testing under subcontract to FGL. RBI will review the laboratory reports, coordinate with FGL and McCampbell Analytical on any QA/ QC issues, and prepare the data for submission to CIWQS with the SMRs.

TASK 3: TEMPERATURE COMPLIANCE
RBI will conduct daily (weekday) tracking of the San Joaquin River temperature in accordance with procedures developed by RBI under separate contract. This tracking will be conducted in the months identified as having the potential to have a CTF effluent- river temperature differential> 20° F. With initiation of river discharge in April 2023 and based on RBI' s familiarity with other Delta dischargers, the months of November and December 2023 are the months in which tracking will need to be conducted. Ifthe river temperature falls below the temperature identified from the above analysis, then RBI will notify the City and Veolia, so that CTF effluent can be diverted to the cooling ponds.

TASK 4: SEWER RATES EVALUATION
RBI will review the City' s current wastewater rate structure in light of anticipated annual expenses for operating and maintaining the CTF under the new NPDES permit, for preparing Michael King Z i?OBFR1xo1'1 BR1'An! J
City of Lathrop
SolatlnnaforProgress

the reports needed in compliance with the NPDES permit, and continuing to operate the recycled water system. This review also will consider the City' s planned population growth and future needs ( and timing) for expanding the CTF treatment capacity to accommodate planned and approved growth. Based on this review, RBI will provide input to the City' s rate consultant to update the rate consultant' s rate model and then review the model as it is being developed. Ifrate increases are needed, RBI will also consult with City management on approaches to implementing those rate increases.

TASK 5: ADDITIONAL SERVICES
This task provides funding to be used to provide additional RBI services as directed by the City, as the need arises. This facilitates timely and effectively addressing unanticipated or expanded issues as they arise without delays that would otherwise be incurred to seek a contract remedy prior to proceeding. Work under this task will be at the direction of the City Manager or Assistant City Manager.

TASK 6: MEETINGS
This task provides for up to two meetings per month from September 2022 through December 2023 for a total ofthirty-two ( 32) meetings for RBI staff to meet with City staff and its contractors/ consultants to coordinate efforts and obtain information associated with implementing this scope of work. For the purposes of the scope and budget for this task, two 2) hours are assumed for each RBI staff inember attending each meeting, which provides time for meeting/ call preparation, participation, and post- meeting briefings of other parties not attending the meetings.

TASK 7: PROJECT MANAGEMENT
This task provides hours for RBPs Project Manager and Principal- in- Charge to oversee and direct RBI staff efforts on each task and hold key conversations with City staff when needed.

In addition, this task provides time for project coordination by phone, email, and fax with other project team members, budget and schedule tracking, invoicing, and other duties to coordinate/ administer the project.

TASK 8: CTF PROGRAM MANAGEMENT
This task provides funding for RBI' s Project Manager and Principal- in- Charge to assist City staff in identifying and scheduling all tasks that need to be completed ( including tasks lead by other parties) to: ( 1) coordinate all necessary monitoring and reporting under the NPDES permit, and ( 2) maintain compliant operations. RBI will ensure that all necessary coordination among Veolia, PACE, Woodard& Curran, City, RBI, and others happens when needed. This will ensure that appropriate and timely actions are assigned to the proper parties to facilitate operating the CTF in a manner that is efficient, complies with its permits, and consolidates its permits in a
timely manner to minimizing regulatory reporting efforts. The management Michael King Ros ox- BRIArL l
City of Lathrop
SoluCrons tarProgress
November 7, 2022

Page 5 ends

efforts under this task do not include hours for managing the implementation of RBI' s technical tasks identified herein, which is budgeted under Task 7.

Additional Assumptions of this Scope of Work
The level of effort for this scope is limited to the hours budgeted. Should additional services be requested due to additional requests of City staff that are not identified herein, or should analyses of greater scope or depth than identified and budgeted herein be required, RBI will notify the City to discuss the extent of any out-of-scope services needed/requested. Should out-of-scope services be requested by the City, RBI will submit a supplemental scope and fee proposal for those services.

II. SCHEDULE
RBI can begin providing professional services associated with the tasks defined herein upon receipt of a signed contract or written authorization to proceed.

III. CONTRACT AND BILLING ARRANGEMENT
RBI will complete the scope of work defined herein on a time- and- materials basis, with an authorized budget as shown in Attachment 1. RBI will not exceed the authorized budget amount without written approval. Attachment 1 provides an estimated breakdown of the total budget by task based on RBI' s 2022 rates ( Attachment 2) for work activities completed October through December 15, 2022, and according to its 2023 rate schedule ( Attachment 3) for all services provided between December 16, 2022 and December 31, 2023.

If you have any questions regarding this proposal, please do not hesitate to contact me at 916) 261- 4043. We look forward to continuing to assist the City with its NPDES permitting and compliance needs.

Sincerely,
Michael Bryan, Ph. D.
