FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: SECONDARY TREATMENT AREA CABLE REPLACEMENT AT PLANT NO.1,PROJECT NO. FR1-0023 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Receive and file Bid Tabulation and Recommendation for Secondary Treatment Area Cable Replacement at Plant No. 1, Project No. FR1-0023; B. Award a Construction Contract Agreement to Big Sky Electric, Inc., for Secondary Treatment Area Cable Replacement at Plant No. 1, Project No. FR1-0023, for a total amount not to exceed $298,102; and C. Approve a contingency of $59,600 (20%). BACKGROUND Orange County Sanitation District (OC San)operates an effluent junction box at Plant No.1 that conveys treated effluent to the Plant No.2 ocean outfall.OC San also supports the Orange County Water District’s (OCWD’s)Groundwater Replenishment System (GWRS)by supplying electrical power from Power Building 8 to the GWRS Metering Vault located at Plant No.1.After the initial construction of the GWRS, OCWD took over the operation of the metering vault. RELEVANT STANDARDS ·Comply with California Public Contract Code Section 20103.8,award construction contract to lowest responsive, responsible bidder ·24/7/365 treatment plant reliability PROBLEM The power cable to the effluent junction box shows signs of failure and the power and control cables serving OCWD GWRS metering vault at Plant No.1 are damaged.The condition of these cables affects the reliability of electrical service needed to support effluent conveyance to Plant No.2 and the transfer of flow to OCWD. Orange County Sanitation District Printed on 2/23/2026Page 1 of 3 powered by Legistar™ File #:2025-4351 Agenda Date:3/4/2026 Agenda Item No:2. PROPOSED SOLUTION Award a construction contract agreement to replace damaged power and control cables for the GWRS metering vault.These cables will be fed from the adjacent OCWD screenings electrical room instead of Power Building 8.This project will also replace power cables between the Plant No.1 12kV Service Center and the effluent junction box. TIMING CONCERNS Delaying the project award increases the risk of additional power and control cable failure at the GWRS metering vault and a failure of the power cable to the effluent junction box. RAMIFICATIONS OF NOT TAKING ACTION If the damaged cables to the GWRS metering vault fail,OCWD will lose the flow signal to their control system and will need to manually operate the valve to control the flow from OC San’s Plant No.1 trickling filters,and/or will need to pump out the metering vault with an external pump if it floods.If the power cable to OC San’s effluent junction box fails,flow to Plant No.2 will need to be manually controlled. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION OC San advertised Project No.FR1-0023 for bids on September 9,2025,and two sealed bids were received on October 21, 2025. A summary of the bid opening follows: Engineer’s Estimate $ 750,000 Bidder Amount of Bid Big Sky Electric, Inc.$ 298,102 Minako America Corporation, dba Minco Construction $ 877,700 The bids were evaluated in accordance with OC San’s policies and procedures.A notice was sent to all bidders on February 11,2026,informing them of the intent of OC San staff to recommend award of the Construction Contract Agreement to Big Sky Electric,Inc.The difference between the engineer’s estimate and the contractor’s estimate was mainly due to the engineer’s estimate using higher markups,having longer generator rental durations,and over estimating subcontractor markups. Staff recommends awarding a Construction Contract Agreement to the lowest responsive and responsible bidder, Big Sky Electric, Inc., for a total amount not to exceed $298,102. Orange County Sanitation District Printed on 2/23/2026Page 2 of 3 powered by Legistar™ File #:2025-4351 Agenda Date:3/4/2026 Agenda Item No:2. CEQA The project is exempt from CEQA under the Class 1 categorical exemptions set forth in California Code of Regulations section 15301.A Notice of Exemption will be filed with the OC Clerk-Recorder and State Clearinghouse after OC San's Board of Directors approval of the construction contract agreement. FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Budget Update FY 2025-26,Page 33,Repairs &Maintenance)and the budget is sufficient for the recommended action.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: TRICKLING FILTER ODOR CONTROL STUDY AT PLANT NO. 1, PROJECT NO. PS24-04 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Approve a Professional Services Agreement with Black & Veatch Corporation to provide engineering services for the Trickling Filter Odor Control Study at Plant No. 1, Project No. PS24-04, for an amount not to exceed $548,506; and B. Approve a contingency of $54,851 (10%). BACKGROUND The Orange County Sanitation District (OC San)has long utilized trickling filters at Plant No.1. Trickling filters provide secondary level treatment for wastewater.In 2006,OC San replaced its original four trickling filters with two new trickling filters and secondary clarifiers as part of Project No. P1-76,Trickling Filter Rehabilitation and New Clarifiers at Plant No.1.These trickling filters are a key unit process to maintain plant operations and meet operational requirements. The trickling filters at Plant No.1 have had issues with the creation of nuisance odors.OC San has previously reviewed this issue in feasibility studies and as part of SP-166,Odor Control Master Plan. These efforts identified the installation of covers and associated foul air treatment systems as a potential solution;however,structural standards have changed and may impact the viability of cover installation.There are also significant operational impacts associated with cover installation that may require further modifications. These trickling filters are currently scheduled to undergo media replacement and rehabilitation as part of Project P1-142, Trickling Filter Media Replacement at Plant No. 1. RELEVANT STANDARDS ·Less than 12 events for the collection system, under normal operations ·Operate and maintain facilities to minimize impacts on surrounding communities,including odor, noise, and lighting Orange County Sanitation District Printed on 2/24/2026Page 1 of 4 powered by Legistar™ File #:2025-4579 Agenda Date:3/4/2026 Agenda Item No:3. PROBLEM During operation,the trickling filters at Plant No.1 have been a source of nuisance odors and related complaints.These complaints have increased over time,and the operating capacity of the trickling filters has been reduced to mitigate odor generation. PROPOSED SOLUTION This Planning Study aims to explore short-term and long-term odor mitigation strategies for the trickling filters at Plant No.1.It will evaluate the feasibility of adding covers to the trickling filter structures,including ventilation and odor control.It will also identify short-term mitigation measures without covering the structures and provide a conceptual design. TIMING CONCERNS N/A RAMIFICATIONS OF NOT TAKING ACTION Trickling filters operation may be reduced to avoid odor complaints.Reducing capacity of this process can lead to additional operational challenges.A clear plan of action to mitigate nuisance odors will not be in place to correct issues in the short- or long-term. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION Consultant Selection: Criterion Weighting Project Understanding and Approach 40% Related Project Experience 30% Project Team and Staff Qualifications 30% OC San advertised for proposals for Trickling Filter Odor Control Study at Plant No.1,Project No. PS24-04,on June 24,2025.The following evaluation criteria were described in the Request for Proposals (RFP) and used to determine the most qualified Consultant. Two proposals were received on August 18,2025,and evaluated in accordance with the evaluation process set forth in OC San’s Purchasing Ordinance OC SAN-6 by a pre-selected Evaluation Team consisting of OC San staff:one project engineer,the Plant No.1 Chief Plant Operator,and one maintenance supervisor.The Evaluation Team also included one non-voting representative from the Contracts Administration Division and one non-voting technical advisor. The Evaluation Team scored the proposal on the established criteria as summarized in the table Orange County Sanitation District Printed on 2/24/2026Page 2 of 4 powered by Legistar™ File #:2025-4579 Agenda Date:3/4/2026 Agenda Item No:3.

Following the interview,each member of the Evaluation Team scored the Consultants based on both the proposals and interviews using the evaluation criteria and weighting described above.Based on the scoring shown below, Black & Veatch Corporation was selected as the most qualified Consultant. Below is the summary of the final scores: Proposer Reviewer Total Score (Max. 100 Points) 1 2 3 Black & Veatch Corporation 90 80 90 87 AtkinsRealis 67 70 77 71 Black &Veatch Corporation submitted a clear and comprehensive approach that demonstrated a thorough understanding of the scope of work. ·The technical proposal was well-prepared,articulating a strong comprehension of OC San’s objectives and the level of effort necessary to conduct a detailed study. ·The proposed project team was well-organized and included representation from all relevant disciplines, reflecting the firm’s depth of experience. ·Furthermore,the interview reinforced Black &Veatch Corporation’s qualifications and confirmed their understanding of the scope of work. Based on the strength of their proposal and interview performance,the Evaluation Team determined that Black & Veatch Corporation is the most qualified firm to execute the scope of work. Review of Fee Proposal and Negotiations: Proposals were accompanied by sealed fee proposals.In accordance with the Purchasing Ordinance,only the fee proposal submitted by the highest-ranked firm was opened,following Orange County Sanitation District Printed on 2/24/2026Page 3 of 4 powered by Legistar™ File #:2025-4579 Agenda Date:3/4/2026 Agenda Item No:3. approval of the Evaluation Committee’s recommendation by the Director of Engineering. Staff conducted initial negotiations with Black &Veatch Corporation to clarify the requirements of the scope of work,the assumptions used for the estimated level of effort,and the proposed approach to meet the goals and objectives for the study.During the negotiations and discussions,it was agreed upon to include optional TASK 4.2 -Electrical and Instrumentation and Control Concept Drawings in the scope or work to provide flexibility to implement a short-term solution quickly if required.This addition resulted in increased labor hours for the project compared to the original fee proposal. In November 2025,the Operations &Maintenance Department informed the Engineering Department that trickling filter operational changes had been recently implemented,including turning off the fans, which resulted in reduced odors and improved treatment.Based on this information,the project scope was re-evaluated,and minor changes were made including to increase field odor sampling and AERMOD dispersion modeling,to reduce electrical and I&C concept design for both short-term and long-term solutions,and to provide high-level recommendations for long-term odor treatment and cover installation requirements.These efforts will help OC San identify the root cause of the odor by analyzing the modeling data and will support short-term and long-term odor control as required. Based on the reduced scope and the re-negotiation,below is the revised level of effort and the final re-negotiated fee. Original Initial Negotiated Final Re-Negotiated Labor Hours 2640 2832 1865 Consultant’s Fee $746,916 $780,020 $548,506 The Consultant’s fringe and overhead costs,which factor into the billing rate,have been substantiated. CEQA N/A FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Budget FY 2024-25 and 2025-26,Section 8,Page 53,Planning Studies Program (M- Studies)) and the budget is sufficient for the recommended action.

Notwithstanding the foregoing, nothing herein shall be construed to require CONSULTANT to indemnify the Indemnified Parties from any Claim arising solely from: (A) the active negligence or willful misconduct of the Indemnified Parties; or (B) a natural disaster or other act of God, such as an earthquake; or (C) the independent action of a third party who is neither one of the Indemnified Parties nor the CONSULTANT, nor its principal, officer, agent, employee, nor CONSULTANT’s supplier, CONSULTANT, Subconsultant, subcontractor, nor anyone employed directly or indirectly by any of them. Exceptions (A) through (B) above shall not apply, and CONSULTANT shall, to the fullest extent permitted by law, indemnify the Indemnified Parties, from Claims arising from more than one cause if any such cause taken alone would otherwise result in the obligation to indemnify hereunder. CONSULTANT’s liability for indemnification hereunder is in addition to any liability CONSULTANT may have to OC SAN for a breach by CONSULTANT of any of the provisions of this Agreement.

Payment to CONSULTANT by any Indemnified Party or the payment or advance of defense costs by any Indemnified Party shall not be a condition precedent to enforcing such Indemnified Party’s rights to indemnification hereunder. In the event a final judgment, arbitration, award, order, settlement, or other final resolution expressly determines that the claim did not arise out of, pertain to, or relate to the negligence, recklessness, or willful misconduct of the CONSULTANT, to any extent, then OC SAN will reimburse CONSULTANT for the reasonable costs of defending the Indemnified Parties against such claims. CONSULTANT’s indemnification obligation hereunder shall survive the expiration or earlier termination of this Agreement until such time as action against the Indemnified Parties for such matter indemnified hereunder is fully and finally barred by the applicable statute of limitations. 24.

SUMMARY This Scope of Work (SOW) requests engineering services to evaluate and seek recommendations to determine the most viable implementation to mitigate odors at the Plant 1 Trickling Filters Secondary Treatment Process Area. II. PLANNING STUDY BACKGROUND AND OBJECTIVES BACKGROUND OC San owns and operates two (2) uncovered trickling filter (TF) units at Plant No. 1. The trickling filters were built in 2006 by Project P1-76, and their primary objective is to remove Biological Oxygen Demand (BODs) from the primary effluent stream and convert them into suspended solids. Due to the TF surface being exposed to the atmosphere, they have been one of the potential nuisance odor sources at Plant No. 1. The odor has been identified as musty in nature, and odor constituents may have been composed of reduced sulfur compounds, ammonia, and volatile organic carbons (VOCs). Depending on the wind direction and weather conditions, odors related to the TF process have been ongoing issues at Plant 1. Therefore, the trickling filters have been operating at reduced flow to minimize the nuisance impacts to the public. Meanwhile, the TF units are being operated to provide the Ground Water Replenishment System (GWRS) with the aqueous ammonia residual concentration in the TF effluent. (SEE FIGURE 1 for General Site Location) Additionally, in 2017, P1-126 Feasibility Study and SP-166 Odor Control Master Plan (OCMP) considered options to cover the trickling filters and explored other means to minimize odor. The Odor Control Master Plan specifically recommended placing covers on the trickling filters and treating foul air with new single-stage chemical scrubbers. It was also reported that trickling filters were designed to have sufficient structural support for a geodesic dome if it is required in the future. The P1-126 concept report and the OCMP are important reference documents that are attached to this scope Consequently, this Planning Study (PS24-04) will conduct a dedicated study to identify both short-term and long-term TF odor mitigation strategies to potentially allow the trickling filters to continue operating at their design capacity and find viable ways to address the odor issues. January 2026 Page 4 of 18 PS24-04 – Trickling Filter Odor Control Study at Plant No. 1 Figure 1 – General Site Location GENERAL PROJECT DESCRIPTION This Scope of Work (SOW) requests engineering services to conduct a planning study to evaluate and make recommendations to determine a viable TF odor control technology at Plant 1. The study will include: a. Analysis of odor control technology alternatives based on OC San odor control policy and strategic plan, including: i. Evaluations and recommendations of both short-term and long-term odor mitigation strategies. ii. Recommendations for odor control systems based on the existing facilities/landscape and other relevant factors such as life cycle cost & Operations and Maintenance costs Trickling Filters at Plant 1 January 2026 Page 5 of 18 PS24-04 – Trickling Filter Odor Control Study at Plant No. 1 Tasks 1 through 3 assessments will be submitted as Chapters, culminating in a Planning Study Report. The final report will outline conceptual design, implementation plans, project schedule, and construction cost estimate for CIP project planning for the preferred short-term odor control alternative. Additionally, high level recommendations will be made for a long term odor control system as well as modifications of operations and maintenance as required.

PROJECT EXECUTION TASK 1 - REVIEW EXISTING DATA AND PERFORM FIELD SAMPLING (Chapter 1) The CONSULTANT shall evaluate the relevant data, record drawings, documents, reports that will be provided by OC San staff. The existing data available will include: - TF and Secondary Clarifiers treatment record drawings,. - TF operational philosophy and Operations Manual and Practices (OMaPs). - Prior studies related to TF odor control such as P1-126 conceptual report and Odor Control Master Plan. - Available air quality sampling data and foul air constituents’ concentrations. - Previous TF concrete assessment. -P1-142 media replacement project information and condition assessment data. The CONSULTANT’s Odor Control Task Lead and Project Manager shall attend a one-day field visit for field testing, sampling, and trickling filter observation. Should sampling not be completed during this visit, CONSULTANT’s Odor Control Task Lead shall attend a field visit on a second day to complete sampling. The Consultant shall assess condition of the trickling filters using the data provided in reports supplemented with any visual observations from the field visit and make recommendations for any further inspection or condition assessment. CONSULTANT shall develop sampling protocol to be approved by OC San ahead of the field visit. During the field visit, the CONSULTANT shall perform testing, wastewater sampling, and odor sampling as follows: - Fan performance: For evaluation of fan performance, CONSULTANT shall document airflow of each blower during the field investigation using pressure gauge readings and fan curves (or other available means that does not include fan testing) and compare to their rated capacity. Fans would need to be operational for this effort. Should fans not be operational during the sampling field visit, it is assumed that OC SAN can provide this data. - Wastewater sampling: OC SAN shall supply two samples of primary effluent for analysis. o Jar test: The CONSULTANT shall use the first sample to measure dissolved sulfide concentration, pH, and ORP. A jar test shall then be performed using hydrogen peroxide (H₂O₂) to determine the appropriate dosing rate and reaction time required to fully oxidize sulfides present in the liquid phase. o Shake test: The CONSULTANT shall use the second sample for a “shake test” to evaluate the stripping potential of hydrogen sulfide (H₂S) and reduced sulfur compounds. Colorimetric (Draeger) tubes shall be used for this analysis for three odorants (methyl mercaptan, hydrogen sulfide, and dimethyl sulfide). Results from the shake test will provide an indication of the odor potential associated with the trickling filters’ distribution arm. January 2026 Page 7 of 18 PS24-04 – Trickling Filter Odor Control Study at Plant No. 1 - Vapor phase odor sampling: o Continuous sampling: CONSULTANT shall perform continuous H2S sampling over a two-week period using Acrulog H2S dataloggers. A total of eight Acrulogs are assumed, four per trickling filter; two at the trickling filter surface (ideally, one mounted to the distribution arm and one behind the distribution arm), one in the trickling filter’s plenum at the bottom, and one downstream of the fan from a sampling port at the exhaust stack . Fans shall be operational for exhaust stack measurement and vent doors should be closed during fan operation. If feasible, one continuous week of sampling shall be conducted with the fans operational and one continuous week with the fans off. Should OC SAN elect to only turn fans off at night, the exact timing of the operation of the fans shall be logged by OC SAN and provided to BV. The continuous sampling will serve as an observation of odors over time and will show the diurnal variations and duration of odor events. CONSULTANT shall return to the site after the two-week sampling period to retrieve Acrulogs. o Instantaneous sampling: CONSULTANT will collect instantaneous samples at the trickling filter surfaces and ventilation ports using colorimetric (Drager) tubes for three odorants (methyl mercaptan, hydrogen sulfide, and dimethyl sulfide). o Odor sampling: Consultant will take four air samples for lab analysis for odor units and SIFT analysis for total reduced sulfur compounds. These results will serve as inputs to the dispersion model. Consultant will use a flux chamber to collect samples in 10L Tedlar bags from the surface of one trickling filter and from the vent doors during “fan off” operation. After the fans have been turned on, CONSULTANT shall take a second set of samples from the surface of the trickling filter and from the sample port in the exhaust stack. It is assumed that odor generation is similar in both TFs and samples from one TF are representative for both trickling filters. o Spot checks: During field visit, CONSULTANT shall use a Jerome meter for instantaneous spot checking of H2S around the trickling filters and adjacent fenceline. - Air Velocity and Movement: CONSULTANT shall use an anemometer to check air velocity at the surface of trickling filters and at the trickling filter natural ventilation ports when ports are uncovered and fans are non-operational. CONSULTANT will utilize a smoke pen to verify direction of air movement with fans operational and non-operational. CONSULTANT will compare collected field data to existing data and coordinate with OC SAN for confirmation on data to use for odor control assessment (Tasks 2 and 3) and dispersion modeling (Task 5) prior to initiating those tasks. The CONSULTANT shall document the Task 1 effort in the first chapter of the Planning Study. Upon receipt of review comments from OC SAN, CONSULTANT shall incorporate comments with the updated Chapter submitted with the Draft Planning Study Report.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: ENGINEERING PROGRAM CONTRACT PERFORMANCE REPORT GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Receive and file the Engineering Program Contract Performance Report for the period ending December 31, 2025. BACKGROUND The Engineering Program involves awarding and managing multiple construction and consulting contracts.In 2008,the Orange County Sanitation District (OC San)Board of Directors began authorizing contingencies along with construction and consulting contracts,allowing the General Manager to approve construction change orders and amendments to consulting contracts up to the amount of the authorized contingency.This practice reduces administrative costs,expedites resolution of project issues that arise,helps avoid contractor delay claims,and facilitates efficient management of many contracts. The Engineering Program Contract Performance Report summarizes construction and consulting contract performance and activities for the quarter ending December 31,2025.This report is updated quarterly and includes a summary of the General Manager approved contract contingencies among other key performance indicators.

While the greatest effort occurs during construction, careful attention in the earlier stages is critical to minimize changes later, helping to control costs and avoid overruns while ensuring successful project delivery. 151 Projects $4,145,391,052 TotalProjectsBudget AllOCS j h h d dlif l b i i i h j Project Count by Phase 03-ProjectDevelopment 04-PreliminaryDesign 05-Design 06-BidandAward 07-Construction 09-Close-Out 27 13 29 2 53 27 1 ྦྷ d l bli h h ll i h h li i d Project Budget by Phase 03-ProjectDevelopment 04-PreliminaryDesign 05-Design 06-Bid andAward 07-Construction 09-Close-Out $564,857,700 $105,757,029 $1,691,201,800 $5,938,000 $1,515,051,186 $262,585,337 2/18/2026Print Date: Quarter End Date: 12/31/2025 Active Contracts Overview 136 Contracts $1,206,511,610 TotalContractsValue While projects represent the work OC San plans and manages, contracts reflect the formal obligations we hold with external partners.

One purpose of this report is to track how much of that contingency is ultimately used. Because change order rates are only meaningful once a project is complete, the chart below includes only contracts closed since OC San began formally approving contingencies in 2008. It illustrates how cumulative change order rates have evolved over time for plant- related projects, collection system work, and all contracts combined. *Cumulativedatabeginning in2008.Chartshowslast15years. 4 ྦྷ CCCCCCCooooonnnnnttttttrrrrraaaaacccccttttttsssss CCCCCCCllllllllooooossssseeeeedddddddd LLLLLLLaaaaassssstttttt QQQQQQQuuuuuaaaaarrrrrtttttteeeeerrrrr bbbbbbbbyyyyy PPPPPPPrrrrrooooojjjjjjjjoooooeeeeeccccctttttt CCCCCCCooooonnnnnttttttrrrrraaaaacccccttttttsssss OOOOOOOrrrrriiiiiiiigggggiiiiiiiinnnnnaaaaallllllll CCCCCCCooooonnnnnttttttrrrrraaaaaccccctttttt CCCCCCChhhhhhhhaaaaannnnngggggeeeee OOOOOOOrrrrrddddddddeeeeerrrrrsssss 2010 2015 2020 2025 Goal: Plant - New: 5% Goal: Plant - Rehab: 8% Goal: Collections: 10% 5.5% 9.4%9.5% 5.2% 4.8% 4.0% 2.1%2.6%3.7% 7.1% 7.8% 4.1% 2/18/2026Print Date: Quarter End Date: 12/31/2025 Active Engineering Service Agreements This page provides a view into active professional services contracts, illustrating both the distribution by contract type and the pace of expenditures to date.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: SECONDARY TREATMENT VFD REPLACEMENTS AT PLANT NO.2 AND VFD REPLACEMENTS AT PLANT NO. 1, PROJECT NOS. FE19-08 AND FR1-0011 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Receive and file Bid Tabulation and Recommendation for Secondary Treatment VFD Replacements at Plant No. 2 and VFD Replacements at Plant No. 1, Project Nos. FE19-08 and FR1-0011; B. Award a Construction Contract Agreement to Big Sky Electric, Inc. for Secondary Treatment VFD Replacements at Plant No. 2 and VFD Replacements at Plant No. 1, Project Nos. FE19- 08 and FR1-0011, for an amount not to exceed $3,424,300; and C. Approve a contingency of $342,430 (10%). BACKGROUND Orange County Sanitation District (OC San)operates multiple pump stations and treatment facilities at Plant No.1 and Plant No.2 that are critical to wastewater treatment operations and regulatory compliance.These facilities use pumps equipped with variable frequency drives (VFDs)to control pump speed in response to changing flow and process conditions and to support reliable and efficient operations. At Plant No.1,the City Water Pump Station,Trickling Filter Pump Station,and Return Activated Sludge (RAS)Pump Station support key treatment and utility functions.The City Water Pump Station provides potable water to the Plant,the Trickling Filter Pump Station conveys primary effluent to the trickling filters for treatment,and the RAS Pump Station returns process flow to the front of the Activated Sludge Facility No.1.These pump stations include a total of six VFDs:two at the City Water Pump Station, three at the Trickling Filter Pump Station, and one at the RAS Pump Station. At Plant No.2,the Activated Sludge Facility includes fourteen pumps ranging from 50 to 300 horsepower,equipped with VFDs to control pump speed.These VFDs were installed between 2004 and 2007 and are now at the end of their useful life.Replacement parts and manufacturer support services are no longer available.The pumps driven by these VFDs are critical to operations and Orange County Sanitation District Printed on 2/25/2026Page 1 of 3 powered by Legistar™ File #:2025-4617 Agenda Date:3/4/2026 Agenda Item No:5. services are no longer available.The pumps driven by these VFDs are critical to operations and permit compliance. RELEVANT STANDARDS ·Maintain a proactive asset management program ·24/7/365 treatment plant reliability PROBLEM Construction contracts were awarded by the OC San Board to ACS Engineering,Inc.,(ASCE)in March 2022 (Project No.FE19-08)and December 2022 (Project No.FR1-0011).Notices to Proceed were issued on June 7,2022,and February 28,2023,respectively.During construction,ACSE incurred performance issues,including vendor stop payment notices,which resulted in OC San issuing non-compliance letters and notices of pending damages.In addition,ACSE’s contractor’s license was suspended during this time,which prevented them from performing the work.Despite notification to the surety and multiple opportunities to correct the deficiencies,ACSE failed to resolve the issues and was subsequently terminated for cause.The remaining construction services were turned over to the assigned surety.OC San staff concluded that it would be most expeditious to complete the projects through a direct contract with a completion contractor.OC San will finalize an agreement with surety to recover incurred costs for this change. PROPOSED SOLUTION Award a construction contract agreement to Big Sky Electric,Inc.to replace VFDs at the end of their useful life. TIMING CONCERNS Delaying replacement of these VFDs increases the risk for reduced secondary capacity if the VFDs cannot be repaired because parts or vendor support are not available. RAMIFICATIONS OF NOT TAKING ACTION Not replacing these VFDs increases the risk that critical pumps would not be available for service, reducing treatment capacity, and potentially impacting regulatory compliance. PRIOR COMMITTEE/BOARD ACTIONS December 2022 -Received and filed Bid Tabulation and Recommendation for VFD Replacements at Plant No.1,Project No.FR1-0011;awarded a Construction Contract to ACS Engineering,Inc.for VFD Replacements at Plant No.1,Project No.FR1-0011,for a total amount not to exceed $1,214,888;approved a contingency of $121,488 (10%);found that VFD Replacements at Plant No. 1,Project No.FR1-0011 is exempt from CEQA under the Class 1 categorical exemptions set forth in California Code of Regulations Section 15301;and authorized staff to file a Notice of Exemption with the OC Clerk-Recorder. March 2022 -Received and filed Bid Tabulation and Recommendation for Secondary Treatment VFD Orange County Sanitation District Printed on 2/25/2026Page 2 of 3 powered by Legistar™ File #:2025-4617 Agenda Date:3/4/2026 Agenda Item No:5. March 2022 -Received and filed Bid Tabulation and Recommendation for Secondary Treatment VFD Replacements at Plant No.2,Project No.FE19-08;received and filed Orange County Sanitation District’s Notice of Intent to Award dated January 27,2022;received and filed Award Protest from LEED Electric,Inc.dated February 2,2022,concerning the award to ACS Engineering;received and filed Orange County Sanitation District’s determination letter dated February 10,2022 to LEED Electric,Inc.responding to award protest;awarded a Construction Contract to ACS Engineering for Secondary Treatment VFD Replacements at Plant No.2,Project No.FE19-08,for an amount not to exceed $1,433,000; and approved a contingency of $143,300 (10%). ADDITIONAL INFORMATION Upon a contractor’s default,a public agency may complete a project with another contractor without further competitive bidding.(Shore v.Central Contra Costa Sanitary District (1962)208 Cal.App.2d 465).Under this authority,OC San elected to enter into a direct contract with Big Sky Electric,Inc.to complete the remaining work.This procurement approach provides OC San with greater control over contractor engagement,project scope,and construction management,and is intended to mitigate any further schedule delays and potential cost impacts. CEQA The project is exempt from CEQA under the Class 1 categorical exemptions set forth in California Code of Regulations section 15301 and a Notice of Exemption has been filed with the OC Clerk- Recorder and State Clearinghouse. FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Budget Update FY 2025-25,Appendix A,Page A ‑ 8,Small Construction Projects Program (Project No.M-FE)and under the Repairs &Maintenance budget for the Operations and Maintenance Department, Page 33) and the budget is sufficient for the recommended action.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: NEWHOPE-PLACENTIA SEWER MANHOLE REPLACEMENTS, PROJECT NO. FE21-08 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Approve a contingency increase of $456,000 to the existing Construction Contract Agreement with Sancon Technologies,Inc.,for Newhope-Placentia Sewer Manhole Replacements,Project No.FE21- 08, for a new total contingency of $1,537,902 (378%). BACKGROUND Orange County Sanitation District (OC San)operates and maintains the Newhope-Placentia Trunk Sewer system,which includes several manhole structures originally constructed in 1958.As part of a previously approved construction contract for the Newhope-Placentia Sewer Manhole Replacements project, OC San identified three manholes for repair or rehabilitation to extend their service life. In September 2025,the OC San Board of Directors approved an urgent contingency increase to the existing construction contract to allow partial replacement of Manholes NHP0020 and NHP0135 rather than just rehabilitation.The estimated costs were based only on the scope of work known at the time. In October 2025,OC San assessed the condition of Manhole NHP0135 and confirmed that it is in similar condition to Manhole NHP0020 and would require partial replacement rather than rehabilitation. As of January 2026,Manhole NHP0020,located near the Plant No.1 entrance,has been reconstructed.The condition of the third manhole included in the contract was also assessed and confirmed to be suitable for rehabilitation as originally planned. A visual assessment of the Manhole NHP0205 concrete determined that it was in good enough condition to be coated under OC San’s blanket manhole maintenance repair contract.As a result, Manhole NHP0205 has been removed from this project. Orange County Sanitation District Printed on 2/23/2026Page 1 of 3 powered by Legistar™ File #:2026-4756 Agenda Date:3/4/2026 Agenda Item No:6. RELEVANT STANDARDS ·Comply with California Public Contract Code Section 20103.8,award construction contract to lowest responsive, responsible bidder ·Commitment to safety & reducing risk in all operations PROBLEM The actual costs for replacement of Manhole NHP0020 increased due to significantly higher than normal flows in the existing 51”sewer during construction,substantially less usable concrete in the existing base,and unsuitable backfill material around the manhole.The higher sewer flows and severely corroded channel made reconstructing the manhole base far more difficult than anticipated, and the unsuitable soil had to be replaced with slurry to finish backfilling before rain hit the area. These increased costs exceeded the original cost estimate provided by the contractor. The cost for Manhole NHP0135 was estimated before a detailed design for partial replacement was prepared.The detailed design determined that the partial replacement of Manhole NHP0135 is more complex than originally anticipated.While relocation of one interfering waterline was identified and assumed in the September contingency increase,the effort now requires relocation of two waterlines, additional paving and enhanced traffic control.The majority of the traffic control for Manhole NHP0135 is located in the City of Santa Ana and is affected by their paving moratorium,requiring the slurry sealing,and restriping of all affected lanes.This additional scope was not anticipated in the original contract nor in the prior contingency authorization. A portion of the requested contingency increase is also needed to restore project contingency to address potential unknown conditions that may still arise during construction. PROPOSED SOLUTION Approve a contingency increase to allow OC San to complete the partial replacement of Manhole NHP0135. TIMING CONCERNS Delaying approval of this contingency increase would delay completion of the remaining work associated with the replacement of Manhole NHP0135,increasing the risk that the manhole cannot be repaired promptly. RAMIFICATIONS OF NOT TAKING ACTION If no action is taken,the deterioration will worsen for Manhole NHP0135,increasing the risk of structural failure and ultimately requiring emergency replacement at a significantly higher cost and with greater impact to OC San and the surrounding community.

The major revenue sources are as follows: • Service Fees • Permit User Fees • Capital Facilities Capacity Charges (CFCC) • Property Taxes • Interest • Other Revenue • Debt Proceeds FY2026-27 FY2027-28 Service Fees – User fees are ongoing fees for service paid by customers connected to the sewer system. A property owner, or user, does not pay user fees until connected to the sewer system and receiving services. Once connected, a user is responsible for his share of the system’s costs, both fixed and variable, in proportion to his demand on the system. These fees are for both Single Family Residences (SFR) and Multiple Family Residences (MFR). FY 2026-27 will be the forth year of the most recent five-year sewer service fee rate schedule to be approved by the Board. The SFR rate (the underlying basis for all sewer rates) will increase by 3.4 percent ($13) to $397 in FY 2026-27, and 3.65 percent ($14) to $411 in FY 2027-28. These rates are still well below the average annual sewer rate currently being charged throughout the state. $372.8 $395.3 2 FY2026-27 FY2027-28 Permit User Fees – Fees paid by large industrial and commercial properties owners connected to the sewer system. These fees are for the owner’s share of the system’s costs, both fixed and variable, in proportion to his demand on the system. Since the inception of the Permit User Fee program in 1970, users of OC San’s system that discharge high volumes or high strength wastewater are required to obtain a discharge permit and pay for the full cost of service. $22.1M $22.9M Capital Facilities Capacity Charges (CFCC) – Capital Facilities Capacity Charge is a one-time, non- discriminatory charge imposed at the time a building or structure is newly connected to OC San’s system, directly or indirectly, or an existing structure or category of use is expanded or increased. This charge pays for OC San facilities in existence at the time the charge is imposed, or to pay for new facilities to be constructed in the future, that are of benefit to the property being charged. $16.3M $16.8M Property Taxes – The County is permitted by State law (Proposition 13) to levy taxes at 1% of full market value (at time of purchase) and can increase the assessed value no more than 2% per year. OC San receives a share of the basic levy proportionate to what was received in the 1976 to 1978 period less $3.5 million, the amount that represents the State’s permanent annual diversion from special districts to school districts that began in 1992-93. OC San’s share of this revenue is dedicated for the payment of debt service. $145.7M $148.7M Interest – Interest earnings are generated from the investment of accumulated reserves consisting of a cash flow/contingency, a capital improvement, a renewal/replacement, and a self- insurance reserve. $37.5M $37.2M Other Revenue – Other revenue includes solids handling and capital assessments from the Irvine Ranch Water District (IRWD); and O&M sewer services provided to IRWD, the Santa Ana Watershed Protection Authority (SAWPA), Capital Improvement Program reimbursements from OCWD, and the Sunset Beach Sanitary District. $32.2M $52.5M 3 FY2026-27 FY2027-28 Debt Proceeds – Certificates of Participation (COPs) are OC San’s primary mechanism for financing capital projects. COPs are repayment obligations based on a lease or installment sale agreement. COPs are viewed by the State of California as a share in an installment arrangement where OC San serves as the purchaser. No new debt issuances are projected in the near-term. $0.0M $0.0M Financing If it is necessary that OC San utilize debt financing to meet its total obligations and to meet projected construction schedules, OC San uses long-term borrowing (Certificates of Participation (COP)) for capital improvements that cannot be financed from current revenue. Before any new debt is issued, the impact of debt service payments on total annual fixed costs is analyzed. No new debt issuance is currently being planned. OC San Maintains its AAA Rating OC San maintains ratings of “AAA” from Standards and Poor and “AAA” from Fitch. A triple A rating is the highest obtainable for any governmental agency. To maintain this rating, OC San adheres to its 2023 Debt Policy and coverage ratios requirements. This Board-adopted policy serves as the agency’s guide in the management of existing debt and in the issuance of future debt. OC San Has Contractual Covenants OC San has contractual covenants within the existing COP agreements which require minimum coverage ratios of 1.25. The minimum coverage ratio is the ratio of net annual revenues available for debt service requirements to total annual debt service requirements for all senior lien COP debt. The coverage ratio for senior lien COP debt was approved at 5.68 for FY 2026-27. Orange County Sanitation District Reserve Summary - FY 2025-26 Orange County Sanitation District (OC San) has a Board of Directors Reserve Policy that sets forth seven criteria to be used to determine its reserve level. As part of the OC San financial and operating process, we have developed a Reserve Policy which governs the establishment of our reserve level and the use of those funds. To ensure an adequate and diverse reserve policy, we have established seven different criteria. These are not seven different reserves, but seven criteria used to set the total reserve level. Reserves can only be used with the approval of the Board of Directors. Below is a summary of the OC San Reserve Criteria. Reserve Policy Summary Non-Discretionary 1) Debt Covenants and Other Requirements – Required by OC San bondholders – $57 million – RESTRICTED This level is set by various bond covenants. As OC San issues debt, it is required to maintain certain levels of reserves held specifically for repayment of that debt and cannot be reduced or used prior to repayment of all outstanding debt issuances. 2) “Dry Period” – Property Tax Payments – 50% of Operating Costs – $126 million The largest portion of OC San revenues are user fees, approximately $360 million. These fees are listed on and collected through the County property tax bill. Since we receive payments twice each year, we hold funds in reserve specifically to pay operating expenses pending receipt of those payments. 3) “Dry Period” – Property Tax Payments – 100% of August Debt Service Costs – $13 million The largest portion of OC San revenues are user fees, approximately $360 million. These fees are listed on and collected through the County property tax bill. Since we receive payments twice each year, we hold funds in reserve specifically to pay debt service pending the receipt of those payments. Discretionary 4) Operating Budget – 10% of the total Operating Budget as a Contingency – $25 million We hold ten percent of our operating budget as an operating contingency for non-recurring and unanticipated expenditures. 5) Capital Improvement Budget – 50% of the average 10-year CIP Program – $178 million OC San currently has a ten-year, $3.6 billion Capital Improvement effort. We hold the equivalent of 5% of that total as a contingency specifically related to these Capital Improvement Program efforts. 6) Rehabilitation and Refurbishment – $75 million In 2002, OC San established a reserve level related to rehabilitation efforts at $50 million based on the rehabilitation or replacement costs at that time. Although the total costs for rehabilitation or replacement has increased substantially since 2002 as a result of the move to Full Secondary Treatment and the Construction of GWRS, this reserve guideline has been increased to $75 million. 7) Catastrophic loss / Self-insurance – $100 million OC San is Self-Insured for Catastrophic Loss. $100 million of OC San’s total reserves are related to holding funds for this category. Although OC San now has approximately $14 billion in asset replacement value and this level has been increased, it is potentially under-funded.
