FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: INDUSTRIAL CONTROL SYSTEM AND IT DATA CENTER RELOCATION AT PLANT NO.1, PROJECT NO. P1-138 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Approve a Professional Design Services Agreement with Lee + Ro, Inc., to provide engineering services for Industrial Control System and IT Data Center Relocation at Plant No. 1, Project No. P1-138, for an amount not to exceed $2,354,485; and B. Approve a contingency of $235,449 (10%). BACKGROUND Power Building 3A (PB-3A)at Plant No.1 is over 30 years old.As part of Headworks Rehabilitation at Plant No.1,Project No.P1-105,a new Power Building 3 (PB-3)is being constructed to replace PB -3A and its associated equipment.PB-3 includes a new server room designed to house future Industrial Control System (ICS) and IT data center equipment. RELEVANT STANDARDS ·Comply with California Government Code Section 4526 to engage the best qualified firm “on the basis of demonstrated competence and qualifications”and “negotiate fair and reasonable fees” ·Maintain a culture of improving efficiency to reduce the cost to provide the current service level or standard ·24/7/365 treatment plant reliability PROBLEM The existing server room in the Plant No.1 Control Center has insufficient cooling and power capacity for new IT data center equipment.Additionally,the fiber optics cannot accommodate the higher network speeds,and communication infrastructure in the basement,where there is a flood risk. Orange County Sanitation District Printed on 6/25/2025Page 1 of 4 powered by Legistar™ File #:2025-4063 Agenda Date:7/2/2025 Agenda Item No:2. PROPOSED SOLUTION Award a professional design services agreement to equip the new PB-3 server room with the necessary equipment,backup power,communications infrastructure,and air conditioning.The work includes rerouting fiber optic cables to accommodate the relocation of the server room and planned demolition of PB-3A and providing new fiber optics that meet the higher network speed requirements. Upon completion,PB-3A will be demolished and the existing Control Center server room will be converted back into office space. TIMING CONCERNS The future IT data center equipment for the ICS and office networks cannot be installed until the new server room is operational. RAMIFICATIONS OF NOT TAKING ACTION If no action is taken,the existing Control Center server room will require significant upgrades, including new server racks,additional cooling,additional backup power,and new fiber optics and network cables. The flooding risk at the Control Center basement will remain unresolved. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION Consultant Selection: OC San requested and advertised for proposals on October 8,2024.The following evaluation criteria were described in the Request for Proposals (RFP)and used to determine the most qualified Consultant. CRITERION WEIGHT Project Understanding and Approach 50% Related Project Experience 10% Project Team and Staff Qualifications 40% One proposal was received on November 21,2024.A follow-up survey was immediately sent to firms listed on the Planholders list.Three firms provided responses with the following reasons for not submitting proposals:(1)unable to submit due to internal resource constraints,(2)unable to secure a subcontractor to perform the required field investigation,and (3)determined that the scope of the subcontracted field investigation was too extensive and preferred projects with more design work. The proposal was evaluated in accordance with the evaluation process set forth in OC San’s Purchasing Ordinance,OC SAN-61 (Purchasing Ordinance),by a pre-selected Evaluation Team consisting of OC San staff. An interview was conducted on February 25,2025,seeking clarifications on the proposal.After theOrange County Sanitation District Printed on 6/25/2025Page 2 of 4 powered by Legistar™ File #:2025-4063 Agenda Date:7/2/2025 Agenda Item No:2. An interview was conducted on February 25,2025,seeking clarifications on the proposal.After the interview,the Evaluation Team scored the proposal on the established criteria as summarized in the table below: Proposer Project Understanding and Approach (Max. 50 Points) Related Project Experience (Max. 10 Points) Project Team and Staff Qualifications (Max. 40 Points) Total Score (Max. 100 Points) Lee + Ro, Inc.38 8 29 75 Review of Fee Proposal and Negotiations: Lee +Ro,Inc.’s proposal was accompanied by a sealed fee proposal.In accordance with the Purchasing Ordinance,the fee proposal was opened after approval by the Director of Engineering based on the Evaluation Committee’s recommendation. Staff negotiated with Lee +Ro,Inc.,to clarify the project scope,assumptions used in estimating the work effort,and the proposed approach.Discussions focused on assigning appropriate personnel, reducing unnecessary drawings and meetings, and refining design deliverables. Additionally,staff revisited the project’s construction cost estimate,which forms the basis for the initial design budget.This review identified deficiencies,resulting in a revised construction cost estimate increase from $4,270,000 to $9,375,000.These figures do not include owner-furnished equipment, which consists of IT equipment,estimated at an additional $7,100,000.Although this equipment is not part of the construction cost estimate,the project requires its installation and commissioning. Therefore,the design consultant must account for it to ensure the design adequately supports its integration and functionality. Original Fee Proposal Negotiated Fee Total Hours 13,568 10,199 Total Fee $3,257,565 $2,354,485 The negotiated fee decreased the overall level of effort for the project primarily due to the following factors: ·Reduced number of Design Memos (DM) from 22 to 7 by consolidating smaller DMs ·Reduced number of sheets required from 190 sheets to 154 sheets ·Reduced PDR Production Workshops from 19 to 14 ·Reduced PDR Focus Meetings from 23 to 14 by consolidating smaller topics ·Reduced Project Coordination Meetings from 12 to 6 ·Reduced hours for on-inspection during the Final Design ·Reduced hours for Bid Support Services ·Reduced hours for each meeting and workshop ·Replaced Project Engineer paid at Lead Engineer level with one at Senior Engineer level ·Reduced hours for the Lead Electrical Engineer,Lead Network Architect,Lead Civil/Structural Engineer,and Senior Engineer,as the Project Engineer already covers responsibilities in Orange County Sanitation District Printed on 6/25/2025Page 3 of 4 powered by Legistar™ File #:2025-4063 Agenda Date:7/2/2025 Agenda Item No:2. Engineer,and Senior Engineer,as the Project Engineer already covers responsibilities in these areas ·Eliminated proposed potholing services from subcontractor, T2UE ·Overall,these reductions represent a focused effort to optimize project delivery while maintaining design quality The Consultant’s fringe and overhead costs,which factor into the billing rate,have been substantiated.The contract profit is 6.24%,which is based on an established formula based on OC San’s standard design agreements.Staff is requesting a 10 percent contingency to address potential revisions as the project progresses through preliminary and final design. Based on the above,staff have determined that the final negotiated fee is fair and reasonable for the level of effort required for this project and recommends award of the Professional Design Services Agreement to Lee + Ro, Inc. CEQA The project scope of work is included in the “Headworks Rehabilitation at Plant No.1 (Project No.P1 -105)” Mitigated Negative Declaration (MND), State Clearinghouse Number 2019049152. FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Proposed Budget Update FY 2025-26,Page A-7,Industrial Control System &IT Data Center Relocation at Plant No.1,Project No.P1-138)and the budget is sufficient for the recommended action.

INDEMNIFICATION To the fullest extent permitted by law, CONSULTANT shall indemnify, defend (at CONSULTANT’s sole cost and expense and with legal counsel approved by OC SAN, which approval shall not be unreasonably withheld), protect and hold harmless OC SAN and all of OC SAN’s officers, directors, employees, consultants, and agents (collectively the “Indemnified Parties”), from and against any and all claims, damages, liabilities, causes of action, suits, arbitration awards, losses, judgments, fines, penalties, costs and expenses (including, without limitation, attorneys’ fees, disbursements and court costs, and all other professional, expert or CONSULTANT’s fees and costs and OC SAN’s general and administrative expenses; individually, a “Claim”; collectively, “Claims”) which may arise from or are in any manner related, directly or indirectly, to any work performed, or any operations, activities, or services provided by CONSULTANT in carrying out its obligations under this Agreement to the extent of the negligent, recklessness and/or willful misconduct of CONSULTANT, its principals, officers, agents, employees, CONSULTANT’s suppliers, CONSULTANT, Subconsultants, subcontractors, and/or anyone employed directly or indirectly by any of them, regardless of any contributing negligence or strict liability of an Indemnified Party. 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. Under no circumstances shall the insurance requirements and limits set forth in this Agreement be construed to limit CONSULTANT’s indemnification obligation or other liability hereunder. The terms of this Agreement are contractual and the result of negotiation between the parties hereto. Accordingly, any PDSA PROJECT NO. P1-138 Revised 073024 INDUSTRIAL CONTROL SYSTEM AND IT DATA CENTER RELOCATION AT PLANT NO. 1 Page 18 of 20 rule of construction of contracts (including, without limitation, California Civil Code Section 1654) that ambiguities are to be construed against the drafting party, shall not be employed in the interpretation of this Agreement. 23. DUTY TO DEFEND The duty to defend hereunder is wholly independent of and separate from the duty to indemnify and such duty to defend shall exist regardless of any ultimate liability of CONSULTANT and shall be consistent with Civil Code Section 2782.8. Such defense obligation shall arise immediately upon presentation of a Claim by any person if, without regard to the merit of the Claim, such Claim could potentially result in an obligation to indemnify one or more Indemnified Parties, and upon written notice of such Claim being provided to CONSULTANT. 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. CONSULTANT PERFORMANCE The CONSULTANT’s performance shall be evaluated by OC SAN. A copy of the evaluation shall be sent to the CONSULTANT for comment.

Investigation of existing utilities shall be in accordance with the respective ASCE guidelines, except as amended by this Scope of Work. A brief description of the ASCE guidelines defines the Quality Level of detail for researching subsurface utilities as follows: • Quality Level D: Information derived from existing records or oral recollections. • Quality Level C: Information obtained by surveying and plotting visible above-ground utility features and by using professional judgment in correlating this information to Quality Level D information. • Quality Level B: Information obtained through the application of appropriate surface geophysical methods to determine the existence and approximate position of subsurface utilities. Quality Level B data shall be reproducible by surface geophysics, such as ground penetrating radar, at any point of their depiction. This information is surveyed to applicable tolerances and reduced onto plan documents. • Quality Level A: Precise horizontal and vertical location of utilities obtained by the actual exposure (or verification of previously exposed subsurface and surveyed utilities) and subsequent measurement of subsurface utilities, usually at a specific point. Minimally intrusive excavation equipment is typically used to minimize the potential for utility damage. A precise horizontal and vertical location, as well as other utility attributes, is shown on the plan documents. Accuracy is typically set to 15-mm vertical and to applicable horizontal survey and mapping accuracy. 5.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: TRUCK LOADING BAY ODOR CONTROL IMPROVEMENTS AT PLANT NO.2,PROJECT NO.P2- 140 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Approve a Professional Design Services Agreement with CDM Smith, Inc., to provide engineering services for Truck Loading Bay Odor Control Improvements at Plant No. 2, Project No. P2-140, for an amount not to exceed $899,800; and B. Approve a contingency of $89,980 (10%). BACKGROUND Orange County Sanitation District (OC San)Plant No.2 Solids Storage and Truck Loading facility was built in 2000 and consists of two biosolid storage bins and two truck loading bays.This facility stores biosolids produced from the solids dewatering process and loads them onto trucks for transport.Odors from the storage bins and the dewatering process are treated using biofilters and odors from the truck loading bays are treated using chemical scrubbers.These odor control systems were installed in 2019.At the same time,fast-opening roll-up doors were added to the north end of each loading bay.At that time,it was assumed that ocean winds typically blew from the south.As a result,doors were not installed on the south end,since odors were not expected to escape in that direction.The open south end of each loading bay was also intended to provide fresh air to support the chemical scrubber system. RELEVANT STANDARDS ·Comply with California Government Code Section 4526 to engage the best qualified firm “on the basis of demonstrated competence and qualifications”and “negotiate fair and reasonable fees” ·Operate and maintain facilities to minimize impacts on surrounding communities,including odor, noise, and lighting ·Safe, beneficial reuse of Biosolids Orange County Sanitation District Printed on 6/24/2025Page 1 of 4 powered by Legistar™ File #:2025-4170 Agenda Date:7/2/2025 Agenda Item No:3. PROBLEM Despite the installation of chemical scrubbers and a north side door in 2019,OC San has continued to experience odor issues at the truck loading bays since the installation of dewatering centrifuges. To address this,a planning study was completed to evaluate the odors and identify potential solutions.The study determined that inadequate odor containment and capture were the primary causes of the issue.Specifically,foul air escapes through the open south exit when the north door is opened for truck entry. Additionally, the lack of negative pressure allows odors to escape. PROPOSED SOLUTION Approve a professional design services agreement to improve the facility’s ability to capture nuisance odors by installing roll up doors on the south end of each loading bay and extending the facility for safety and pedestrian egress when the roll up doors are closed.The project will also install a new air intake system, modify the existing exhaust system, and install other ancillary improvements. TIMING CONCERNS Delaying this project will result in continued odor complaints at the facility. RAMIFICATIONS OF NOT TAKING ACTION Without improvements, the current odor control measures will remain ineffective. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION Consultant Selection: OC San requested and advertised for proposals on January 10,2025.The following evaluation criteria were described in the Request for Proposals (RFP)and used to determine the most qualified consultant. CRITERION WEIGHT Project Understanding and Approach 35% Related Project Experience 30% Project Team and Staff Qualifications 35% Four proposals were received on March 26,2025,and evaluated in accordance with the evaluation process set forth in OC San’s Board of Directors Purchasing Ordinance OC SAN-61 (Purchasing Ordinance) by a pre-selected Evaluation Team consisting of OC San staff. Orange County Sanitation District Printed on 6/24/2025Page 2 of 4 powered by Legistar™ File #:2025-4170 Agenda Date:7/2/2025 Agenda Item No:3. The Evaluation Team scored the proposals on the established criteria as summarized in the table below: Firm Approach (Max 35) Related Experience (Max 30) Team (Max 35) Total Score (Max 100) 1 CDM Smith Inc.28 23 28 79 2 Carollo Engineers, Inc.22 27 26 75 3 Lee + Ro, Inc.25 22 22 69 4 GHD Inc.28 17 22 67 Based on this scoring,two consultants were shortlisted for interviews on April 7,2025.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, CDM Smith, Inc., was selected as the most qualified consultant. Consultant Approach (Max 35) Related Experience (Max 30) Team (Max 35) Total Score (Max 100) 1 CDM Smith Inc.30 22 29 81 2 Carollo Engineers, Inc.25 25 26 76 CDM Smith,Inc.excelled in both the technical proposal and interview evaluations.The technical proposal demonstrated an understanding of major elements of the project and the project risks.The proposal reflected the consultant’s awareness of construction sequencing and the importance of maintaining operations. The interview presentation demonstrated a cohesive team operating within an appropriate organizational structure.The selected consultant demonstrated awareness of permitting needs. They also emphasized the importance of communication and active engagement with OC San’s staff during both the design and construction phases.Therefore,the Evaluation Team determined that CDM Smith, Inc., is the most qualified firm to complete the project scope. Review of Fee Proposal and Negotiations: Proposals were accompanied by sealed fee proposals.In accordance with the Purchasing Ordinance,the fee proposal of only the highest-ranked firm was opened after approval by the Director of Engineering of the Evaluation Committee’s recommendation. Staff conducted negotiations with CDM Smith,Inc.,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 project.These discussions occurred over two negotiation meetings with the main outcome listed below: The level of effort was increased based on clarifications to the project scope and a task to model the Orange County Sanitation District Printed on 6/24/2025Page 3 of 4 powered by Legistar™ File #:2025-4170 Agenda Date:7/2/2025 Agenda Item No:3. The level of effort was increased based on clarifications to the project scope and a task to model the air flow in the truck loading bay to validate the planning study recommendations. Original Fee Proposal Negotiated Fee Total Hours 3,850 4,355 Total Fee $789,666 $899,800 The consultant’s fringe and overhead costs,which factor into the billing rate,have been substantiated.The contract profit is 8.98%,which is based on an established formula determined by OC San’s standard design agreements.Staff is requesting a 10 percent contingency to address potential revisions as the project progresses through preliminary and final design. Based on the above,staff has determined that the final negotiated fee is fair and reasonable for the level of effort required for this project,and recommends award of the Professional Design Services Agreement to CDM Smith, Inc. CEQA The project is exempt from CEQA under the Class 1 categorical exemptions set forth in California Code of Regulations sections 15301,because it involves rehabilitation and minor alterations of existing facilities involving no expansion of use or capacity.A Notice of Exemption will be filed with the OC Clerk-Recorder and State Clearing House after the Orange County Sanitation District’s Board of Directors award of the construction contract. FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Proposed Budget Update FY 2025-26,Page A-6,Truck Loading Bay Odor Control Improvements at Plant No.2,Project No.P2-140)and the budget is sufficient for the recommended action.

INDEMNIFICATION To the fullest extent permitted by law, CONSULTANT shall indemnify, defend (at CONSULTANT’s sole cost and expense and with legal counsel approved by OC SAN, which approval shall not be unreasonably withheld), protect and hold harmless OC SAN and all of OC SAN’s officers, directors, employees, consultants, and agents (collectively the “Indemnified Parties”), from and against any and all claims, damages, liabilities, causes of action, suits, arbitration awards, losses, judgments, fines, penalties, costs and expenses (including, without limitation, attorneys’ fees, disbursements and court costs, and all other professional, expert or CONSULTANT’s fees and costs and OC SAN’s general and administrative expenses; individually, a “Claim”; collectively, “Claims”) which PDSA PROJECT NO. P2-140 Revised 050625 TRUCK LOADING BAY ODOR CONTROL IMPROVEMENTS AT PLANT NO. 2 Page 17 of 20 may arise from or are in any manner related, directly or indirectly, to any work performed, or any operations, activities, or services provided by CONSULTANT in carrying out its obligations under this Agreement to the extent of the negligent, recklessness and/or willful misconduct of CONSULTANT, its principals, officers, agents, employees, CONSULTANT’s suppliers, CONSULTANT, Subconsultants, subcontractors, and/or anyone employed directly or indirectly by any of them, regardless of any contributing negligence or strict liability of an Indemnified Party. 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. Under no circumstances shall the insurance requirements and limits set forth in this Agreement be construed to limit CONSULTANT’s indemnification obligation or other liability hereunder. The terms of this Agreement are contractual and the result of negotiation between the parties hereto. Accordingly, any rule of construction of contracts (including, without limitation, California Civil Code Section 1654) that ambiguities are to be construed against the drafting party, shall not be employed in the interpretation of this Agreement. 23. DUTY TO DEFEND The duty to defend hereunder is wholly independent of and separate from the duty to indemnify and such duty to defend shall exist regardless of any ultimate liability of CONSULTANT and shall be consistent with Civil Code Section 2782.8. Such defense obligation shall arise immediately upon presentation of a Claim by any person if, without regard to the merit of the Claim, such Claim could potentially result in an obligation to indemnify one or more Indemnified Parties, and upon written notice of such Claim being provided to CONSULTANT. 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. PDSA PROJECT NO. P2-140 Revised 050625 TRUCK LOADING BAY ODOR CONTROL IMPROVEMENTS AT PLANT NO. 2 Page 18 of 20 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. CONSULTANT PERFORMANCE The CONSULTANT’s performance shall be evaluated by OC SAN. A copy of the evaluation shall be sent to the CONSULTANT for comment. The evaluation, together with the comments, shall be retained by OC SAN and may be considered in future CONSULTANT selection processes. 25. COMPLIANCE WITH OC SAN POLICIES AND PROCEDURES CONSULTANT shall comply with all OC SAN policies and procedures including the Contractor Safety Standards, as applicable, all of which may be amended from time to time. 26. CLOSEOUT When OC SAN determines that all work authorized under the Agreement is fully complete and that OC SAN requires no further work from CONSULTANT, or the Agreement is otherwise terminated or expires in accordance with the terms of the Agreement, OC SAN shall give the Consultant written notice that the Agreement will be closed out. CONSULTANT shall submit all outstanding billings, work submittals, deliverables, reports or similarly related documents as required under the Agreement within thirty (30) days of receipt of notice of Agreement closeout. Upon receipt of CONSULTANT’s submittals, OC SAN shall commence a closeout audit of the Agreement and will either: i. Give the CONSULTANT a final Agreement Acceptance: or ii. Advise the CONSULTANT in writing of any outstanding item or items which must be furnished, completed, or corrected at the CONSULTANT’s cost. CONSULTANT shall be required to provide adequate resources to fully support any administrative closeout efforts identified in this Agreement. Such support must be provided within the timeframe requested by OC SAN. Notwithstanding the final Agreement Acceptance the CONSULTANT will not be relieved of its obligations hereunder, nor will the CONSULTANT be relieved of its obligations to complete any portions of the work, the non-completion of which were not disclosed to OC SAN (regardless of whether such nondisclosures were fraudulent, negligent, or otherwise); and the CONSULTANT shall remain obligated under all those provisions of the Agreement which expressly or by their nature extend beyond and survive final Agreement Acceptance. Any failure by OC SAN to reject the work or to reject the CONSULTANT’s request for final Agreement Acceptance as set forth above shall not be deemed to be acceptance of PDSA PROJECT NO. P2-140 Revised 050625 TRUCK LOADING BAY ODOR CONTROL IMPROVEMENTS AT PLANT NO. 2 Page 19 of 20 the work by OC SAN for any purpose nor imply acceptance of, or agreement with, the CONSULTANT’s request for final Agreement Acceptance. 27. ENTIRE AGREEMENT This Agreement constitutes the entire understanding and agreement between the Parties and supersedes all previous negotiations between them pertaining to the subject matter thereof. PDSA PROJECT NO. P2-140 Revised 050625 TRUCK LOADING BAY ODOR CONTROL IMPROVEMENTS AT PLANT NO. 2 Page 20 of 20 IN WITNESS WHEREOF, this Agreement has been executed in the name of OC SAN and CONSULTANT by their respective duly authorized officers as of the day and year first written above.

CONSULTANT shall secure the services of a Professional Fire Protection Engineer licensed in the State of California to determine fire protection requirements, develop and prepare preliminary design documents, and prepare final plans and specifications. 1.1 BACKGROUND Orange County Sanitation District (OC SAN) Plant No. 2 Solids Storage and Truck Loading facility, consisting of two biosolids storage bins (Bin A and Bin B), and two truck loading bays (Bay A and Bay B) under them, was built in 2000 by P2-60 Project. This facility stores and loads the biosolids produced from the solids dewatering process (centrifuges) to the contracted hauling trucks. The foul air from the storage bins combined with odorous air from the centrifuge dewatering process is treated by biofilters while the foul air from the truck loading bays is treated by Truck Loading Scrubbers A and B, two chemical scrubbers. These biofilter and chemical scrubbers were added when the existing dewatering centrifuge facility was built in 2019 by P2-92 and P2-92A Projects, respectively. In addition to adding scrubbers, P2- 92A Project added one fast opening roll-up door at the north end of each loading bay. Assuming that the prevailing wind from the ocean would always blow into the building from the south, no door on the south end nor supply air was deemed necessary under P2-92A (i.e., no odor would escape from the south openings). Despite addition of chemical scrubbers and north side door in 2019, OC SAN has been experiencing odor issues at the truck loading bays since the installation of dewatering centrifuges that replaced the belt-filter press dewatering at Plant No. 2. This issue resulted in conducting Planning Study PS20-03 in 2022 to evaluate the odor release at these loading bays and to develop solutions to mitigate it. PS20-03 concluded that the poor odor containment and capture were the cause of the odor issues at Plant No. 2 biosolids truck loading bays. Foul air continuously escapes from the south exit that has no door at each bay. The lack of south exit doors also allows natural breezes to sweep odors out of the bays when the north entrance door opens for trucks to enter the bays. The existing exhaust ducts do not effectively draw foul air from the entire space inside the bays, and the lack of negative pressure allows odors to escape. The solutions and corrective actions for these identified issues by PS20-03 formed the project elements of P2-140 Project. 1.2 GENERAL PROJECT DESCRIPTION The primary purpose of this project is to resolve the odor capture and containment deficiency of truck loading bays odor control system at OC SAN Plant No. 2. This is achieved by adding a south truck exit roll-up door at each of the bays. To allow sufficient space for OC SAN staff and the biosolid truck drivers to walk around the trucks inside the bays (after adding the new roll-up doors and accounting for the existing site constraints such as tunnels) the project will extend each of the loading bays by 4 feet. 06-17-2025 - Final P2-140 – Design SOW Page 6 of 46 Enclosing the loading bays by adding the south roll-up doors also requires adding egress doors to each bay to allow the drivers and OC SAN staff to safely enter and exit the bays. As such, two egress doors will be added to the south and north end of each bay’s exterior wall accounting for the existing site obstructions and constrains (total of 4 doors). To improve the collection of odors, the project will replace and reconfigure the existing ventilation ducts at both bays and will add supply air fans. The new duct systems and registers need to draw foul air from the lower and celling levels of the bays to eliminate any dead zones per recommendations provided in PS20-03 and pursuant to this study’s smoke test results. A platform needs to be added between the bays to support the supply fans and ducts added by this project. This project will not impact the exhaust air duct system outside of the bays leading to the scrubbers. Additional lighting needs to be added to the bays due to the reduction of natural light resulting from adding the south roll-up doors. The new lighting system includes wall mounted LEDs illuminating walkways around the trucks as well as emergency and exit lights. Adding new supply fans and rollup doors also requires modifying the existing MCCs to facilitate the new supply fans’ motor starters and new roll-up door feeder breakers. Gas monitors and alarms also need to be added to each bay to address the safety requirements. Controls and instrumentation for the new equipment will be added and integrated with the existing control system. Lastly, the project is expected to repair any concrete spalling and cracks at the truck loading facility. Figure 1 below illustrates the general boundary and scope of P2-140 project. Figure 1. P2-140 Location Map 06-17-2025 - Final P2-140 – Design SOW Page 7 of 46 1.3 PROJECT EXECUTION PHASES All OC SAN projects are divided into six phases. CONSULTANT shall provide engineering services for all Project Elements listed in this Scope of Work for the following Phases: Phase 1 – Project Development (Not in this Scope of Work) Phase 2 – Preliminary Design Phase 3 – Design Phase 4 – Construction (Not in this Scope of Work) Phase 5 – Commissioning (Not in this Scope of Work) Phase 6 – Close Out (Not in this Scope of Work) 1.4 DESCRIPTION OF PROJECT ELEMENTS Detailed descriptions of the Project Elements are presented below. 1.4.1 PROJECT ELEMENT 1 – STRUCTURAL MODIFICATIONS/REPAIRS A. The biosolid truck loading bay odor control project consists of the following structural modifications: 1. Truck loading bay extension of approximately 4ft at the south end to enclose all hauling truck types and to allow sufficient space to walk around the trucks. 2. Add a roll-up door at each truck loading bay south end (total of 2) to contain odors during and after truck loading. 3. Add two (2) egress doors at each truck loading bay (total of 4) for personnel and truck- drivers to safely enter and leave the truck loading bays. 4. Add roof level platform between the two bays (Bays A and B) to support supply fans and ducts if these fans cannot be located on the existing roof. 5. Repair any concrete spalling or cracks that need repair at the truck loading facility. B. Assumptions for Level of Effort 1. For the purpose of estimating the predesign and design phase levels of effort, the CONSULTANT shall make the following assumptions regarding this project element: a. The loading bay will be extended 4 ft due to site constraints (Tremblay Tunnel and space need for truck turn toward the facility exit gates). In other words, PS20-03’s recommendation on the length of extension does not need to be reevaluated. b. The truck bay extension will not have an impact on the scale since the truck will continue to park at the existing loading position; however, the procedures for entering and exiting the building need to be evaluated and modified due to the addition of the second roll-up door. c. Pursuant to PS20-03 recommendation, the egress doors are required to be on the truck driver’s side wall of loading bay A and passenger’s side wall of the loading bay B due to the obstructions blocking such doors on the interior walls (staircase and hydraulic power units). d. It is OC SAN’s understanding from similar project at Plant 1 that no fire alarm or sprinklers are required to be added to the bays. e. It is OC SAN’s understanding from similar project at Plant 1 that new building permits are not required for this project. f. Installing the supply fans platform requires two openings cut out in the parapet to allow people to walk between the existing roof and the new platform. 06-17-2025 - Final P2-140 – Design SOW Page 8 of 46 g. The new platform height should be sufficient not to interfere with the hydraulic power unit, stairway to the operations room, and the restroom wall mounted exhaust fan below. The height also needs to account for the use of a crane to lift different components of the hydraulic units during its maintenance. h. A phased approach needs to be employed to perform the construction of these structural elements to keep one bay operational at all times. i. No temporary facility is expected to be required at this point due to loading bays redundancy, expectation on completion of all the necessary maintenance projects prior to P2-140 (e.g. screw conveyors or augers and scales repairs and replacements) and proposed phased construction approach by PS20-03. However, CONSULTANT should verify this assumption during PDR and assist with strategizing and preparing shutdowns and contingency plans in collaboration with OC SAN O&M. 1.4.2 PROJECT ELEMENT 2 – VENTILATION SYSTEM MODIFICATIONS A. The biosolid truck loading bay odor control improvement project consists of the following ventilation improvements and modifications: 1. Replace and reconfigure the existing ventilation ducts inside the bays and tie the new ducts into existing air scrubber duct connections at the bay ceilings (both bays). 2. Install two (2) new supply air fans (one standby/one duty) and supply air duct systems. B. Assumptions for Level of Effort 3. For the purpose of estimating the predesign and design phase levels of effort, the CONSULTANT shall make the following assumptions regarding this project element: a. PS20-03 recommended U shape exhaust collection duct system with collectors from the top to the bottom, and the supply air to push fresh air into the bays and sweep the odorous air toward the exhaust system to ensure complete capture and collection based on extensive testing. Assume no further testing is required during design. The results of the testing performed for this planning study and the recommended configuration will be used as the starting point of the design effort and further reviewed and evaluated in the PDR phase. b. The current odor control system’s air permit will need to be modified to include the supply fans. CONSULTANT (or their subconsultant) will prepare the permit modification application package including emission calculations, risk assessment, application forms, regulatory applicability analysis, and application narratives as applicable and implement OC SAN feedback and comments. Due to SCAQMD requiring 2 years to process air permit applications, the permit application needs to be prepared after completion of preliminary design phase and submitted to SCAQMD at the beginning of the design phase. c. Installation of new duct work may require existing lighting fixtures to be relocated or replaced to avoid conflicts with other equipment at the ceiling area. d. No additional building structural modifications are required for this project element. 1.4.3 PROJECT ELEMENT 3 – SAFETY, ELECTRICAL, AND CONTROL SYSTEM IMPROVEMENTS AND ADDITIONS A. The following safety, control system, and electrical improvements and additions will be required as part of this odor improvement project: 1. Add emergency, security, and exit lighting at the egress doors pursuant to OC SAN requirements. 2. Add new lighting to illuminate walking areas. 3. Add carbon monoxide (CO) gas monitoring and alarm system inside the truck loading bays pursuant to OC SAN standards. 06-17-2025 - Final P2-140 – Design SOW Page 9 of 46 4. Add hydrogen sulfide (H2S) gas monitoring and alarm system inside the truck loading bays pursuant to OC SAN standards if it is determined to be required in the preliminary design 5. Modify the existing and add new electrical system to feed the new equipment. 6. Add control and instrumentation for the new equipment and integrate them with the existing control system. B. Assumptions for Level of Effort 1. For the purpose of estimating the predesign and design phase levels of effort, the CONSULTANT shall make the following assumptions regarding this project element: a. It is OC SAN’s understanding that only Carbon Monoxide (CO) monitoring and alarm system are required to be installed at the bays and that hydrogen sulfide (H2S), and hydrogen (H2) gas monitoring and alarm systems are not required for this improvement. These assumptions will be verified as part of the preliminary design tasks. b. According to PS20-03 field assessment, MCC-SMB has sufficient space in the existing MCC to facilitate addition of a new motor starter for the Bay B supply fan and feeder breaker for the new Bay B roll-up door. MCC-SMA does not have adequate space for an 18" motor starter bucket; however, there is sufficient space to the left of MCC-SMA to install a new vertical section for the Bay A supply fan motor starter and roll-up door feeder breaker. c. CONSULTANT is required to develop shutdown coordination table listing each shutdown event, duration, along with associated loads that will be impacted by each shut down and assist with the coordination of these events with OC SAN Operations and Maintenance groups (O&M). d. New conduits required for the new truck bay equipment will be routed from the electrical room to the loading bays via the tunnel system used for existing conduits. e. The traffic light (red or green light) immediately outside each bay south exist need to be relocated. The new location (inside or outside the bay) should be evaluated as part of the preliminary design phase. 1.4.4 COORDINATION WITH OTHER PROJECTS A. The following projects may impact or require coordination with this project. The CONSULTANT shall coordinate with each project and incorporate work restrictions and requirements in the design documents. 1. FE23-04, Truck Loading Scale Replacement at Plant No. 2. This project will replace two truck loading scales at Plant No. 2. The construction phase of this project is currently ongoing and is expected to be completed by the end of 2024. As such, no coordination is anticipated between the two projects as this project is expected to be completed before P2- 140 construction commencement in 2028. 2. J-124, Digester Gas Facility Rehabilitation at Plant 1 and 2. This project will rehabilitate the existing gas compressor facilities at both plants. This includes seismic upgrades to the gas compressor buildings, rehabilitation of electrical and I&C systems, and rehabilitation of other necessary auxiliary equipment. It will also replace the existing flares with low pressure ultra-low emission flares. The staging area of this project is adjacent to those of P2-140. The construction phase of this project is currently scheduled to start and finish in July 2027 and January 2032, respectively, which will completely overlap with construction of P2-140. Therefore, close coordination between these two projects is necessary. 3. P2-128, Plant No. 2 Digester Replacement. This project will build six new anaerobic digesters at Plant No. 2, to be initially operated in mesophilic mode to produce Class B biosolids product and designed for future thermophilic operation to produce Class A product. 06-17-2025 - Final P2-140 – Design SOW Page 10 of 46 Supporting facilities and equipment will include sludge pumping, heating, and mixing; odor control; power distribution; and instrumentation and controls. Future conversion to the thermophilic process as well as replacement and/or demolition of existing digesters will be part of a separate future project. The construction area of this project is adjacent to that of P2-140. The construction phase of this project is currently scheduled to start and finish in November 2028 and June 2036, respectively, which will completely overlap with construction of P2-140. Therefore, close coordination between these two projects is crucial. 4. P2-138, Plant No. 2 Operations and Maintenance Complex. This project will replace the Operations Center building and Maintenance building at Plant No. 2 in the location of the current Maintenance building and will build a new Maintenance cart barn south of the new building. The construction area of this project is adjacent to that of P-140. The construction phase of this project is currently scheduled to start and complete in June 2027 and August 2030, respectively, which will completely overlap with construction of P2-140. Therefore, close coordination between these two projects is essential. 1.5 DESIGN CONSIDERATIONS The following design considerations shall be carried from Preliminary Design through Final Design. 1.5.1 TECHNOLOGY AND CONFIGURATION CHOICES The project elements in this facility shall be achieved using proven technologies.

The PS20-03 study report recommended one configuratfon based on smoke testfng of three alternatfves. To ensure confidence in the selected approach and provide a defensible basis for final design, performance of three alternatfve scenarios including the configuratfon recommended by PS20-03 will be evaluated and compared with the existfng facility’s through CFD modeling. Performance Criteria: The CFD model will be evaluated against the following criteria to determine the effectfveness of each ventflatfon alternatfve: • Maintain negatfve pressure in the loading bay under operatfng conditfons. • Reduce odor constftuent concentratfons, specifically H₂S and ammonia, to levels consistent with or below those cited in the PS20-03 report. • Improve airflow uniformity, eliminatfng dead zones and achieving a proper sweeping flow pattern from air supply to exhaust. • Use the existfng configuratfon (without exhaust fan system) as the baseline to assess relatfve improvements across the alternatfves. • Performance targets will be refined in consultatfon with OC SAN Operatfons staff to ensure alignment with operatfonal goals and regulatory expectatfons. Flow Conditions: The CFD simulatfon will use a steady-state model under a single operatfng conditfon, assuming that the truck bays are symmetrical and that fans operate at constant speed. This approach is appropriate given the relatfvely stable flow conditfons during loading and unloading events. Model Boundaries: The model will define all air inflow and outilow boundaries, representfng the supply fans (inlets) and exhaust registers (outlets). Internal heat and contaminant sources (such as the sludge drop zone) will be simplified to scalar release zones, consistent with species transport modeling assumptfons. Page 2 of 2 P2-140 BIM Modeling: To support a CFD modeling and enhance long-term design value, we are suggestfng laser scanning & BIM model development of the truck loading facility additfon into the scope. This will enable us to develop a high-resolutfon BIM model that captures existfng ductwork, structural features, and spatfal constraints—all of which are important for reliable airflow simulatfon. The process will involve performing laser scanning, followed by the development of a BIM model, which will then be exported into the CFD platiorm for simulatfon. By startfng with more accurate geometry, we can generate realistfc and defensible CFD results that reflect true airflow behavior within the space. In additfon to supportfng this project’s design validatfon, the BIM model will serve as a valuable digital asset for OC SAN’s future modificatfons, maintenance planning, and capital improvements. Model Geometry: Model geometry will be developed using laser scanning and BIM tools. A Revit-based model will be created to capture the shell of a single truck bay and all major architectural and mechanical features, including air inlets, outlets, ductfng, and large equipment. This geometry will be exported to CFD software for simulatfon. Alternatives to be Evaluated: To determine the most effectfve odor collectfon and supply air distributfon configuratfon system, following scenarios will be evaluated and compared through CFD modeling: • Scenario 0: Existfng Facility (Baseline or Reference Scenario) • Scenario 1: PS20-03 Recommended Configuratfon • Scenario 2: Optfmized/Improved Configuratfon 1 • Scenario 3: Optfmized/Improved Configuratfon 2 Scenario 0 will be the startfng point of the modeling exercise where the existfng facility’s model will be developed and calibrated using the available data from PS20-03 tests as well as boundaries and geometry data gathered in the previous steps of the modeling effort. This calibrated model then will be used to develop the models for three other scenarios and used as a reference point to determine the most effectfve configuratfon. Scenarios 2 and 3 models will be developed to either verify PS20-03 recommended configuratfon (Scenario 1) as the most effectfve configuratfon for odor collectfon and supply air distributfon ductfng system or provide opportunitfes for additfonal improvements.

BACKGROUND The Central Generation facilities at Orange County Sanitation District (OC San)Plant Nos.1 and 2 have been in operation for over 30 years.The major support equipment has aged and degraded to varying degrees.To ensure the facilities are reliable,it is necessary to perform extensive boiler cleaning and assess the condition and remaining useful life of the eight (8)Engine Exhaust Heat Recovery Boiler Systems. Staff anticipate that two (2) boilers per year will be assessed. RELEVANT STANDARDS ·Maintain a proactive asset management program ·Protect OC San assets ·Use all practical and effective means for resource recovery Orange County Sanitation District Printed on 6/24/2025Page 1 of 3 powered by Legistar™ File #:2025-4315 Agenda Date:7/2/2025 Agenda Item No:4. PROBLEM The Exhaust Heat Recovery Boilers undergo a yearly in-depth inspection by Hartford Steam Boiler Inspection and Insurance Company to meet annual permitting requirements.OC San has a need for a thorough and comprehensive assessment to address the decline in performance. PROPOSED SOLUTION Establish a Professional Consultant Services Agreement (Agreement)with Pond and Company,Inc. to conduct boiler cleaning to enhance performance.The Agreement will also include a comprehensive internal and external assessment of the boilers to evaluate their current condition and support planning for any necessary repairs or replacement. TIMING CONCERNS Timely approval of the Agreement will allow for the cleaning and assessment efforts of the boilers. This will support OC San’s asset restoration goals,extend service life,and reduce the risk of equipment failures caused by corrosion or other structural issues. RAMIFICATIONS OF NOT TAKING ACTION Without an assessment of the boilers,equipment performance will continue to degrade,leading to reduced efficiency.Potential failures may force critical systems out of service which could impact overall plant reliability and safety. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION A Request for Proposal was issued on January 22,2025,for the Engine Exhaust Heat Recovery Boiler Assessment with one (1)proposal received.Prior to the receipt of the proposal,an evaluation team consisting of various OC San staff was formed.Individual scoring was the chosen method of evaluation for this procurement.Members of the team performed an independent review of the proposal and later met as a group with the Purchasing Representative to discuss their preliminary scores, questions, and concerns. The Proposal was evaluated using standard procurement procedures and found to be acceptable based on the published evaluation criterion.OC San intends on providing two (2)boilers for assessment and cleaning per year.

CS-2025-650BD 1. BACKGROUND The Central Generation facilities at Orange County Sanitation District Plant No. 1 and 2 were completed in 1993, and house Cogeneration facilities, providing power and heat to support miscellaneous wastewater processes. There are three stationary reciprocating internal combustion engine-generator sets at Plant No. 1, and five at Plant No. 2. To support the operation of the engine-generator sets and the wastewater processes as a whole, various types of equipment such as pumps, heat exchangers, pressure vessels, piping, valves, etc. are needed to ensure that the gensets operate as designed. Having been in operation for over 30 years, the major gensets support equipment has aged and degraded to varying degrees. For this reason, it is necessary to periodically assess the health, condition, and remaining useful life of the critical pressure containing components, like pressure vessels, tanks, boilers, heat exchangers, and piping systems. OC San is striving to improve the effectiveness of the current Engine Exhaust Heat Recovery Boilers and the associated preventive maintenance and examination program at both Plant Nos. 1 and 2 Cen Gen facilities. One element of this effort is planning for more standardized, rigorous, and comprehensive internal and external inspections to better understand the conditions of the boilers and their associated systems. 1.1 DEFINITIONS A.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: PRIMARY CLARIFIERS F AND G ROTATING MECHANISM REHABILITATION AT PLANT NO.2, PROJECT NO. FE23-09, SPECIFICATION NO. S-2024-612BD GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Approve a contingency increase of $850,500 (27%)to the existing Services Contract with Vicon Enterprises,Inc.,for Primary Clarifiers F and G Rotating Mechanism Rehabilitation at Plant No.2, Project No.FE23-09,Specification No.S-2024-612BD,for a new total contingency of $1,323,000 (42%). BACKGROUND The A-side Primary Clarifiers (clarifiers),originally constructed in 1962,consist of four circular clarifiers responsible for treating non-reclaimable flows at Orange County Sanitation District (OC San)Plant No.2.During normal operations,three clarifiers are in service,while the fourth is kept in reserve as a backup unit.In February of 2023,Clarifier F failed due to metal loss from corrosion at the connections between the rake arms and center cage structure,which resulted in the failure of the rotating mechanism.An inspection of Clarifier G showed similar levels of corrosion,raising concerns that its rotating mechanisms could fail at any time.Consequently,Clarifiers F and G have remained offline since then. The A-side is currently operating with only Clarifiers D and E in service. RELEVANT STANDARDS ·Meet volume and water quality needs for the GWRS ·24/7/365 treatment plant reliability PROBLEM Currently,only Clarifiers D and E are running,providing no redundancy during dry weather operating conditions due to Clarifiers F and G being out of service.The reduced A-side treatment capacity is straining the secondary treatment process and impacting secondary effluent quality when operating in separated mode for the Orange County Water District’s Ground Water Replenishment System (GWRS). Following the completion of sandblasting,it was discovered that the metal deterioration on the rake Orange County Sanitation District Printed on 6/24/2025Page 1 of 3 powered by Legistar™ File #:2025-4273 Agenda Date:7/2/2025 Agenda Item No:7. Following the completion of sandblasting,it was discovered that the metal deterioration on the rake arms and feed well of Clarifiers F and G,as well as the center column of Clarifier F was significantly greater than originally anticipated.Sandblasting of Clarifier G’s center column has started but remains incomplete;however,similar levels of corrosion are expected based on the findings from Clarifier F.These deteriorated components must be repaired to restore the clarifiers to operational condition. PROPOSED SOLUTION Approve a contingency increase to repair additional corrosion damage to the Primary Clarifiers F and G rake arms and feed well and reinforce the center columns.Out of the total revised contingency of 42%,approximately 6%will be used for pending changes and 24%for rake arm,feed well,and center column repairs.The remaining 12%will be reserved for potential Clarifier F drive repair, unknown conditions, and anticipated time impacts. TIMING CONCERNS The clarifiers are currently operating at a reduced capacity with no available redundancy to maintain plant operations in a separated mode of treatment.Clarifiers F and G need to be rehabilitated and returned to service as soon as possible to restore redundancy and improve overall plant reliability. A-Side Primary Clarifiers Replacement at Plant No.2,Contract No.P2-98A is currently constructing four new A-side clarifiers, which are expected to be completed by late 2027. RAMIFICATIONS OF NOT TAKING ACTION OC San is currently operating the A-Side with only two clarifiers in service.Losing another A-Side clarifier would force plant operations into a combined mode of treatment (bypassing separation for reclaimable and non-reclaimable flows), greatly reducing reclaimable flow to GWRS. PRIOR COMMITTEE/BOARD ACTIONS September 25,2024 -Approved a Services Contract to Vicon Enterprise,Inc.for Primary Clarifiers F and G Rotating Mechanism Rehabilitation at Plant No.2,Project No.FE23-09,Specification No.S- 2024-612BD,for a total amount not to exceed $3,150,000;and approved a contingency of $472,500 (15%).
