APPROVE AMENDMENTS NO. 3 AND NO. 4 WITH RBI TO PROVIDE
ADDITIONAL STUDIES AND PERMIT COMPLIANCE SUPPORT SERVICES FOR CIP WW 20- 17 AND APPROVE BUDGET AMENDMENT
BACKGROUND:
The Surface Water Discharge Project CIP, WW 20- 17 was created to obtain a NPDES permit to discharge effluent generated by the Lathrop Consolidated LCTF to the San Joaquin River in order to minimize future sewer rate increases, and support growth as the City' swastewater flows increase and land becomes unavailable for the storage and disposal of recycled water.
The Regional Water Quality Control Board ( RWQCB) issued the NPDES permit in February 2022, with river discharge commencing on February 1, 2024. On November 8, 2021, City Council approved a PSA with RBI to assist the City with meeting the requirements of the NPDES permit. Amendments No. 1 and No. 2 to the PSA for additional LCTF permit compliance support services RBI were also approved by Council on December 12, 2022 for: 1) one- time tasks to prepare the LCTF for discharge of effluent to the San Joaquin River, and 2) routine tasks needed for the continuing implementation of permit requirements through the end of 2023.
Additional permit compliance services from RBI are needed for; 1) one- time tasks to prepare studies required by the National Marine Fisheries Service Biological Opinion for River Discharge and; 2) routine tasks needed for the continuing implementation of permit requirements through the end of Fiscal Years ( FY) 2023-024 and through FY 2024-025.
RBI has provided three proposals to provide the additional permit compliance support services for a time and materials cost, not to exceed $ 298,9for the one- time tasks needed for studies required by the NMFS Biological Opinion for River Discharge, and 300, 571 for the routine NPDES permit compliance tasks, for a total cost of 598, 860. These services are to be provided under Amendments No. 3 and No. 4 respectively to the PSA for LCTF permit compliance support services as follow:

Subject: Proposal to Conduct a Constituent of Emerging Concern Study for the City of Lathrop Consolidated Treatment Facility Required by the NMFS Biological Opinion for River Discharge
Dear Mr. King:
Robertson -Bryan, Inc. (RBI) has assisted the City of Lathrop ( City) in preparing to discharge treated effluent from its Consolidated Treatment Facility ( CTF) to the San Joaquin River, including obtaining necessary regulatory approvals for construction of the CTF' s San Joaquin River outfall. RBI prepared a National Marine Fisheries Service Biological Assessment and Essential Fish Habitat Assessment for the City ofLathrop Consolidated Treatment Facility Surface Water Discharge Project ( 2020), and subsequent addendums ( collectively, Biological Assessment or BA). The National Marine Fisheries Service ( NFMS) subsequently issued an Endangered Species Act Section 7( a)( 2) Biological Opinion and Magnuson -Stevens Fishery Conservation and Management Act Essential Fish Habitat Response for the City ofLathrop Outfall Installation Project [ 408 Permission Section ( 19535)] (2021; Biological Opinion or BO). The BO addressed potential effects of the City' s discharge to the San Joaquin River on federally listed threatened Central Valley spring -run Chinook salmon ( Oncorhynchus tshawytscha) Evolutionarily Significant Unit, the threatened California Central Valley steelhead ( 0. mykiss) Distinct Population Segment ( DPS), and the threatened southern DPS green sturgeon (Acipenser medirostris) in accordance with Section 7 of the Endangered Species Act ( ESA). The BO identifies conservation measures ( CMs) that must be met by the project to mitigate potential environmental effects of the outfall construction on ESA -listed anadromous fishes potentially occurring in the lower San Joaquin River. This proposal for professional services is provided in regard to CM 15 ( Chemicals of Emerging Concern Study), which is defined in the BO as follows:
Within six months ofinitiating discharge to the San Joaquin River, the City will initiate a monitoring study of chemicals of emerging concern ( CECs). This study will evaluate chemicals of concern to NMFS, but not yet regulated by the Regional Water Board. The study is proposed to monitor undiluted effluent and river water quarterly for two years. River monitoring will occur at a
location( s) where the CTF discharge

has fully mixed with river flows. The City' sconsultant will develop the list of CECs to monitor and route to NMFS stafffor review and approval prior to study initiation.
The City initiated discharge to the San Joaquin River on February 1, 2024, triggering these study requirements. RBI' sscope of work for developing and implementing a CEC study to satisfy CM 15 is provided in the subsequent sections of this proposal.
I. SCOPE OF WORK
TASK 1: CEC SAMPLING AND ANALYSIS PLAN
RBI will prepare a sampling and analysis plan ( SAP) describing a schedule for conducting the CEC study, CECs to be monitored, sampling locations, and other details describing the monitoring study. CEC sampling will occur quarterly for two years as required by CM 15 of the BO. The list of CECs to be monitored will be consistent with California CEC monitoring guidance from Drewes et al. (2023) 1, Tadese ( 2016), and the State Water Resources Control Board Resolution 2013- 0003 recycled water policy. It was assumed, for the purpose of this proposal, that the CECs to be monitored are those recommended by these three guidance documents for monitoring in freshwater because of concerns for potential effects to aquatic life. The proposed list of CECs to be monitored is provided in Attachment 1.
The following three locations will be sampled.
CTF Final Effluent at EFF- 001 or EFF- 002
San Joaquin River upstream of the outfall at RSW- 001
San Joaquin River downstream of the outfall
The downstream San Joaquin River sampling location will be approximately 0. 35 miles downstream of the outfall (fully mixed per RBI mixing zone study) or as informed by the City' s
Effluent Dispersion Study ( CM 14) to confirm where effluent mixing with the San Joaquin River is complete.
The SAP will describe sampling conditions that include timing based on flows in the San Joaquin River ( i.e., so that flows will be in the downstream direction for sufficient time to ensure that effluent is not present at the upstream sample location), that sampling will only Drewes, J.E., P.

occur when the CTF is discharging to the river, avoiding sampling when there is stormwater discharge from the MS4 outfall between RSW- 001 and the CTF outfall, and avoiding sampling during facility maintenance or episodic storm events when discharge and river flows are not representative of typical conditions. The SAP also will describe effluent and water quality constituents that will be measured at the time of sampling ( i.e., dissolved oxygen, pH, conductivity, and temperature). Effluent flow will be recorded from meters established by the City and San Joaquin River flow will be obtained from the San Joaquin River California Data Exchange Center (CDEC) station at the Mossdale Bridge3. Data quality objectives, quality assurance and quality control samples, sample container types, volumes, analytical methods, method detection limits, reporting limits, and quality control limits also will be presented.
A draft SAP will be provided to the City for review and a revised draft SAP will be provided to NMFS for review. After which, the SAP will be finalized. The budget assumes that the preliminary list of CECs identified by RBI in the SAP is approved by NMFS.
Deliverables:
Draft CEC Sampling and Analysis Plan for review by the City Revised Draft CEC Sampling and Analysis Plan for submittal to NMFS Final CEC Sampling and Analysis Plan
TASK 2: FIELD SAMPLING
RBI will conduct CEC sampling and coordinate analysis with the City and Eurofins Test America ( West Sacramento, CA). CECs are often new compounds that are not common in typical analyses. Thus, most commercial laboratories do not offer all or even some of the analyses needed for this study. Eurofins Test America provides analyses for all CEC listed in Attachment 1 and has reporting limits sufficiently low to meet monitoring recommendations.
The budget includes the costs of analysis and Eurofins Test America will be contracted directly by RBI. Prior to sampling, RBI will contact the City to ensure sampling conditions are met and for access to the CTF and San Joaquin River. The analytical laboratory also will be contacted prior to sampling to supply sample containers that will be prepared for sample collection by RBI. Field preparation will include equipment calibration and decontamination.
Two RBI staff will mobilize to the field during each of the eight sampling events to collect grab samples of final effluent at the CTF and San Joaquin River and document field conditions at the outfall and at sampling locations in the river. River water samples will be collected from the riverbank using a pole to access surface water not influenced by near -shore disturbances. Each sampling event is expected to be conducted in a single day and samples will be shipped by overnight courier or taken directly to the analytical laboratory. 3 https:// cdec. water. ca. gov/ index. html

Reports and electronic data deliverables ( EDDs) received from the analytical laboratory will be reviewed to identify any deviations from data quality objectives in the SAP and to determine if corrective actions are needed to address any issues in the next sampling event.
RBI will discuss any data issues and any necessary actions to remedy the issues with the City.
TASK 3: REPORTING
RBI will review, analyze, and report data collected during the CEC study. The focus of the data report will be to fully implement CM 15 of the BO by presenting the CEC analytical results. The report also will describe the methods used for this CEC study, field data collected at the time of sampling, any deviations from data quality objectives described in the SAP, and any corrective actions taken.
A draft report will be provided to the City for review. Upon request, RBI also will meet with the City via conference call to discuss the draft report and findings. RBI will prepare a final CEC study report that addresses any comments from the City. The final report will be provided to the City in PDF format, complete with any attachments ( i.e., analytical data), for the City to submit to NMFS. RBI can submit this report to NMFS on behalf of the City, upon request.
Deliverables:

TASK 4: PROJECT MANAGEMENT
Project management time shall primarily be used to coordinate and direct project activities to ensure that all tasks are conducted efficiently and effectively. This task also provides time for project coordination by phone and email with other project team members and local/ regional agencies as appropriate, review of budget and invoices, schedule tracking, and other duties to coordinate and administer the project.
II. SCHEDULE
RBI can begin providing professional services associated with the tasks defined herein upon receipt of a contract or written authorization to proceed.
III. CONTRACT AND BILLING ARRANGEMENT
RBI recommends a time -and -materials contract, not to exceed the amount shown in Attachment 2 without written authorization, to provide the professional services outlined herein. RBI will invoice the City monthly according to its annual rates ( Attachment 3) for all RBI work activities completed in the prior month.

Subject: Proposal to Provide Effluent Dispersion Study Professional Services for the City of Lathrop Consolidated Treatment Facility in accordance with Requirements of the NMFS Biological Opinion for River Discharge 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, including obtaining necessary regulatory approvals for construction of the CTF' sSan Joaquin River outfall. RBI prepared a National Marine Fisheries Service Biological Assessment and Essential Fish Habitat Assessment for the City ofLathrop Consolidated Treatment Facility Surface Water Discharge Project (2020), and subsequent addendums collectively, Biological Assessment or BA). National Marine Fisheries Service ( NFMS) subsequently issued an Endangered Species Act Section 7(a)( 2) Biological Opinion and Magnuson -Stevens Fishery Conservation and Management Act Essential Fish Habitat Response for the City ofLathrop Outfall Installation Project [ 408 Permission Section 19535)] (2021; Biological Opinion or BO). The BO addressed the potential effects ofthe City' s
San Joaquin River discharge on the threatened Central Valley spring -run Chinook salmon ( Oncorhynchus tshawytscha) Evolutionarily Significant Unit, the threatened California Central Valley steelhead ( 0. mykiss) Distinct Population Segment ( DPS), and the threatened southern DPS green sturgeon ( Acipenser medirostris) in accordance with Section 7 of the Endangered Species Act ( ESA). The BO identifies conservation measures (CMs) that must be met by the project to mitigate potential environmental effects of the outfall construction on ESA -listed anadromous fishes potentially occurring in the lower San Joaquin River. This proposal for professional services is provided to assist the City with implementing CM14 (Effluent Dispersion Study), which is specified in the NMFS BO as follows.
Within six months ofinitiating discharge to the San Joaquin River, the City will initiate a dye tracer ( or similar methodology) study to track the actual dispersion patterns of the effluent discharged from the outfall into the San Joaquin River. This study will ensure the inferences made in the BA for the Project prepared by the City, based upon modeled mixing ofeffluent with river flows, is representative ofreal -world conditions. 3100 Zinfandel Dr., Suite 300 Phone 916. 714. 1801

ROBERTSON • BRrAN, INC.
Solutions for Progress
The City initiated discharge to the San Joaquin River on February 1, 2024, triggering these study requirements. RBI' sscope of work for Effluent Dispersion Study ( study) services is provided in the subsequent sections of this proposal.
I. STUDY ASSUMPTIONS
The BO requires the City to conduct a dye tracer study to track dispersion patterns of the CTF effluent discharged to the San Joaquin River through the CTF' soutfall. RBI assumes the use of rhodamine dye for the study. Rhodamine dye is commonly used for this purpose primarily due to its benign character in aquatic environments and chemical stability ( low rate of degradation). RBI has performed several similar studies in Delta water bodies with great success.
It is also assumed that the study will be performed in a single event ( three day duration) during daylight hours. The study design will accommodate these assumptions.
II. SCOPE OF WORK
TASK 1: STUDY WORKPLAN PREPARATION
Under this task, RBI will prepare a workplan that outlines the procedures and schedule for conducting the study. The workplan will define the study approach, methods for field measurement of rhodamine dye concentrations and any other relevant field or water quality parameters measured ( e.g., temperature, electrical conductivity). As part of this task, RBI staff will perform a site visit to the CTF outfall site to confirm the approach identified in the workplan. Additionally, the workplan will identify procedures for post -processing of field data gathered to meet the objectives of the study. The workplan will be provided to the City for review in Microsoft Word format, with any attachments provided in PDF format. Upon receipt of any review comments, RBI will finalize and issue the workplan to the City in PDF format.
TASK 2: STUDY PREPARATION AND COORDINATION
Under this task, RBI will prepare, plan, and coordinate the study with project team members, including the City and any other involved parties. This task will involve procurement and fabrication of field supplies and apparatus necessary for the study. Anticipated supplies and apparatus include rented fluorescent dye monitoring equipment, buoys, anchors, rope, and rhodamine dye.
Budget is provided under this task for routine coordination with project team members in advance of the study. Additional budget is provided for coordination with regulatory authorities, as appropriate, to obtain any necessary approvals for conducting the study.
Budget also is provided under this task for RBI staff to perform a site visit to the CTF outfall site to perform testing of field apparatus prior to the study. This will ensure that the field apparatus is properly suited to achieve the goals of the study.

TASK 3: FIELD STUDY
7 ROBERTSON ' BRI' Rn, Inc
Solutions for Progress
RBI will conduct the field rhodamine dye tracer study at the CTF' soutfall and within its vicinity in the San Joaquin River. The study is anticipated to take place over the course of three days, with the first day dedicated to equipment setup in the field and testing to confirm proper functionality.
The study will be conducted on the second day once equipment setup and functionality has been confirmed. RBI anticipates the use of up to ten ( 10) rhodamine dye measurement sondes, with some placed at strategic locations within the study area and at least one positioned to a boat that will be used to track the effluent plume in the river. On the morning ofthe second day, multiple rhodamine dye slugs will be dosed at the CTF effluent transfer pump station, which will allow the rhodamine dye to be fully mixed in the CTF effluent prior to discharge to the San Joaquin River. Dye slug doses will be staggered to prevent overlapping of the effluent plumes and to allow for tracking ofthe effluent plume via boat.
The third day of the study will primarily be used to retrieve field apparatus deployed during the study, in addition to any remaining data gathering.
For budgeting purposes, it is assumed that three ( 3) RBI staff will be on -site each day during the study.
TASK 4: DATA PROCESSING AND REPORT PREPARATION
After completion of the field tracer study, RBI will download, review, process, and analyze the data collected during the study. The data will be reviewed to ensure that sufficient and accurate data was collected before proceeding with the preparation of the study report. RBI will discuss any data issues with the City and determine any necessary actions to remedy the issues.
Once the data has been adequately analyzed, RBI will prepare a study report documenting the findings from the study. This report will summarize the findings from the field dye tracer study and provide a comparison of the study findings to the modeled effluent dispersion discussed in the BA, in accordance with the requirements of CM14. The report will provide the following:
1. Description of purpose and need;
2. Description of field data collection and methods;
3. Field data results for dye tracer concentrations and other water quality parameters measured;
4. Comparison of field study results to modeled dispersion of CTF effluent in the San Joaquin River included in the NMFS BA; and
5. Study conclusions.
The draft report will be provided to the City for review in Microsoft Word format, with any attachments in PDF format. RBI will then prepare a final report, incorporating any comments Mr. Michael King, P. E.

Task 9: General Compliance Support
Task 10: Project Management
These tasks are explained further in the detailed scope of work and budget provided below.
I. SCOPE OF WORK
TASK 1: COMPLIANCE COORDINATION MEETINGS
This task provides for up to two meetings per month during the six- month recycled water reclamation season ( May —October; 12 meetings) and weekly meetings during the wet season November —April; 25 meetings) when the CTF is likely to be discharging to the San Joaquin River. Weekly coordination is necessary while discharging to the river because of the additional attention needed to comply with the NPDES permit. These meetings will be used by 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 each for two RBI staff members attending each meeting, which provides time for meeting/ call preparation, participation, and post -meeting briefings of other parties not attending the meetings. RBI' sPrincipal -in -Charge is assumed to attend up to eight ( 8) meetings.
TASK 2: EFFLUENT AND RECEIVING WATER MONITORING
Ensuring compliance with the NPDES permit Monitoring and Reporting Program involves the subtasks below.
Subtask 2. 1: Scheduling and Coordination
RBI will update and maintain the monitoring schedule spreadsheet used by RBI, the City, Veolia, Compliance First, and FGL. RBI will coordinate with these parties to ensure they are aware of upcoming sampling, identify issues with sampling dates, ensure bottles are on -hand, review chain of custodies ( COCs), and other related issues.
Subtask 2.: Review and Compile Data
RBI will review and maintain a spreadsheet of monitoring results for routine CTF monitoring data tested at FGL and field data produced by Compliance First. An updated version of this spreadsheet and the final lab reports will be provided to the City with the monthly SMRs or made available through RBI' s Sharefile data portal. RBI will update its internal tracking spreadsheet for trihalomethane ( THM) disinfection byproducts so that we can advise the City and its contractors on the need to collect additional samples, adjust operations to minimize THM formation, and help ensure compliance with THM effluent limitations.
Subtask 2. 3: Characterization Monitoring
The City initiated four quarters of effluent and receiving water characterization monitoring in Q1 2024. RBI will coordinate with the City, Veolia, Compliance First, and FGL to ensure that Mr. Michael King

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/C issues, and prepare the data for submittal to CIWQS with the SMRs. RBI will process the data using the Central Valley Water Board' s reasonable potential analysis tool, which determines if the new characterization data would trigger effluent limitations in the next/ renewed NPDES permit.
Subtask 2. 4: Pyrethroid Pesticides Monitoring
The City initiated four quarters of effluent and receiving water monitoring for pyrethroid pesticides and acute toxicity using the test species, Hyalella aztecca during 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 will collect the receiving water samples, and McCampbell Analytical will conduct the testing under sub -contract to FGL. RBI will review the laboratory reports, coordinate with FGL and McCampbell Analytical on any QA/C issues, and prepare the data for submission to CIWQS with the SMRs. RBI will advise the City on any requirements applicable to the CTF if effluent pyrethroid levels were to exceed the Central Valley Water Board pyrethroid triggers.
TASK 3: ELECTRONIC SELF -MONITORING REPORTS ( ESMRS)
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 Integrated 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.

TASK 4: NPDES PERMIT -REQUIRED PROGRESS REPORTS
RBI will prepare the following annual reports required by the NPDES permit, as well as cover letters for the submittals. Draft reports will be prepared for review and comment by the City.
The City' scomments will be incorporated into a final report for the City to submit to CIWQS.
Annual Operations Report due February 1, 2025
Best Management Practices Plan for Salinity Annual Report due February 1, 2025 Mercury Pollution Prevention Plan Annual Report due February 1, 2025 TASK 5: INDUSTRIAL PRETREATMENT PROGRAM
RBI is currently under contract to implement the City' sIndustrial Pretreatment Program (IPP) for fiscal years 2023/024 and 2024/025. Services provided under that contract include assistance with industrial user permit development, monitoring, and enforcement. Services to be provided under this task include the following subtasks.
Task 5. 1: IPP Approval by Central Valley Water Board
In January 2024, the City submitted its updated IPP, prepared by RBI, to the Central Valley Water Board for approval, in accordance with CTF NPDES permit requirements. RBI is tracking Central Valley Water Board staff' review of the IPP. This task is for RBI to address Mr. Michael King
City of Lathrop
March 6, 2024
IMROBERTSON- BRYON, Inc
Solutions for Progress
Board staff queries regarding the IPP to facilitate its approval. This task is also for RBI to make minor revisions to the IPP in the event Board staff have comments and request changes.
Task 5. 2: Municipal Code Revisions
The IPP update included proposed revisions to the City' s municipal code to local limits, new industrial user definitions, and editorial revisions. This task is for RBI to support the City to revise the municipal code, such as assistance with preparing the staff report and resolution to be considered by City Council.
Task 5. 3: IPP Annual Report
RBI will prepare the IPP Annual Report required by the CTF NPDES permit. This report will address IPP activities in calendar year 2024 and is to be submitted to CIWQS by February 1, 2025. This will be the first IPP Annual Report submittal by the City. The report will address all twelve elements listed in Attachment E, section X. D. 5 (for brevity, these items are not described here). The information and data to address these elements will come from industrial user data, data collected by the City, and inspections conducted by the City.
If the City is not in compliance with the Central Valley Water Board' s pretreatment
audit/ compliance inspection requirements, then the report will include the reasons for noncompliance and state how and when the City will comply with such conditions and requirements.
TASK 6: TOXICITY COMPLIANCE SUPPORT
RBI will assist the City with scheduling, coordination, and reviewing results of routine, quarterly whole effluent toxicity ( WET) testing required by the NPDES permit. RBI will advise the City on whether permit -required accelerated testing or a Toxicity Reduction Evaluation ( TRE) has been triggered. In the event a 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' scontract and that Veolia operations staff will collect the effluent samples used for bioassay testing.
TASK 7: REGULATORY DEVELOPMENTS TRACKING AND REPORTING
The CTF is currently subject of several Central Valley Water Board initiatives, including CV - SALTS, the Delta Regional Monitoring Program ( RMP), the Delta Merucry Control Program and Total Maximum Daily Load ( TMDL), Pyrethroid Control Program, and others. There may be other regulatory initiatives that the CTF would be affected by during FY24/ 25, including the State Water Resources Control Board' sClean Water Act section 303( d) listing process. As approved by the City, RBI will attend meetings for these initiatives, advocate for the City' sinterest, and advise the City on these initiatives and their impacts to the CTF. RBI Mr. Michael King

will cost share these efforts with other RBI clients when feasible. RBI' seffort on these activities is limited by the task budget.
TASK 8: TEMPERATURE MONITORING
RBI will continue to closely monitor CTF effluent and San Joaquin River temperature to identify any potential temperature compliance challenges. This will involve monitoring of effluent temperature in the CTF' s
cooling ponds ( Ponds A and B) to better characterize the amount of cooling provided by these ponds and help PACE identify appropriate changes to the ponds when constructing the Phase 3 upgrades. Budget is included in this task for RBI staff to procure, deploy, and routinely ( quarterly) download data from a temperature logger in
Pond B, obtain effluent temperature data from the CTF' sEffluent Transfer Pump Station, and post -process the data. Budget is provided for RBI staff to travel to the CTF to download data from and perform any necessary maintenance to the temperature logger. RBI will communicate findings from this monitoring to the City in the form of a technical memorandum. Budget is provided for preparation of a single technical memorandum in FY24/ 25.
TASK 9: GENERAL COMPLIANCE AND OPERATIONAL SUPPORT
