System Process Description The Port Burwell WWTP is located at 1 Chatham Street, Ontario.The plant is a Sequential Batch Reaction (SBR)with Aerated Sludge Management.The facility has a rated capacity on 1,060 m3/d and is comprised of the following components: • Wastewater collection system & pumping stations; • Preliminary treatment facility consisting of a bar screen, grit removal and flow equalization tanks; • Biological Treatment facility including 2 SBR's including supplementary treatment system; • Disinfection system; • Biosolids Handling. Raw Wastewater Collection Raw sewage typically flows by gravity through the system to the wastewater treatment plant. Where gravity flow is not possible due to elevation restrictions, raw sewage flows by gravity to each of the eight pump stations that service the Municipality of Bayham and from there the stations discharge to the Port Burwell WWTP via forcemains throughout the collection system. Eight sewage pumping stations transport wastewater from the communities of Eden, Straffordville, Vienna, and Port Burwell. Each station includes: Eden SPS • Pump Station#1 consists of 2 submersible pumps controlled by Milltronics level sensors,with high level float alarm,flow measurement Bioxide addition, emergency back-up generator and Overflow Discharge. Straffordville SPS • Pump Station#2 consists of 2 submersible pumps controlled by Milltronics level sensors,with high level float alarm, emergency back-up generator and Overflow Discharge. • Pump Station#3 consists of 2 submersible pumps controlled by Milltronics level sensors,with high level float alarm and auxiliary portable generator hooked. • Pump Station#4 consists of 2 submersible pumps controlled by Milltronics level sensors,with high level float alarm and auxiliary portable generator hooked. pg. 3 Ontario Clean Water Agency-Port Burwell WWTP& Bayham WWC 2025 Annual Performance Report • Pump Station#5 consists of 2 submersible pumps controlled by Milltronics level sensors,with high level float alarm,flow measurement Bioxide addition emergency back-up generator and Overflow Discharge. Vienna SPS • Pump Station#6 consists of 2 submersible pumps controlled by Milltronics level sensors,with high level float alarm,flow measurement Bioxide addition, emergency back-up generator and Overflow Discharge. Port Burwell SPS • Pump Station#7 consists of 2 submersible pumps controlled by Milltronics level sensors,with high level float alarm, auxiliary portable generator hooked and Overflow Discharge. • Pump Station#8 consists of 2 submersible pumps controlled by Milltronics level sensors,with high level float alarm, auxiliary portable generator hooked and Overflow Discharge. Odour Control Odour control throughout the collection system is supported by Bioxide injection at three pumping stations.These station houses a 1,000-litre Bioxide storage tank and a metering pump delivering up to 1.89 L/h.The introduction of Bioxide into the wastewater stream reduces the formation of hydrogen sulfide,thereby minimizing odours within the sewer network and at downstream facilities. Preliminary Treatment System When wastewater arrives at the facility, it first enters the preliminary treatment works, where solids and grit are removed to protect downstream biological processes.This stage incorporates a mechanical grinder, a manual bar screen and a mechanical auger.A vortex grit separator and grit classifier complete the preliminary treatment process by removing heavy inorganic materials.These components ensure that the wastewater entering the downstream systems is free of coarse debris and abrasive materials. Following screening and grit removal,wastewater flows into a flow equalization tank, which moderates variations in both flow and loading.The equalization tank is equipped with two influent transfer pumps, along with a mixing pump. By attenuating peak flows,the equalization process ensures stable hydraulic conditions for the SBR biological treatment system, improving process efficiency and maintaining consistent treatment performance. Biological Treatment The biological treatment system consists of two SBR units.These reactors operate through sequential cycles of aeration, settling and decanting.The process relies on three aeration blowers,which support the aerobic biological degradation of organic matter and ammonia. Sludge pumps transfer settled solids within the process. After the treatment and settling phases, clarified effluent is decanted from the reactors and conveyed to the disinfection stage.This batch-based biological process provides reliable removal of biochemical oxygen demand, suspended solids and ammonia. pg. 4 Ontario Clean Water Agency-Port Burwell WWTP& Bayham WWC 2025 Annual Performance Report Chemical Treatment To ensure compliance with phosphorus limits, the facility utilizes a chemical dosing system that uses liquid alum to precipitate and remove phosphorus. The system includes a chemical storage tank and two metering pumps. Alum is introduced at controlled rates to maintain effluent phosphorus concentrations within approved compliance limits. Disinfection Disinfection is achieved using ultraviolet (UV) irradiation.The UV system consists of two banks of low-pressure, high-intensity lamps, with ten lamps per bank. As effluent passes through the UV channels,the system inactivates pathogenic organisms, ensuring compliance with bacteriological discharge criteria prior to release to the environment.A Parshall flume downstream of the UV system provides continuous flow measurement of treated effluent. After disinfection,treated effluent is discharged to Big Otter Creek through a gravity outfall equipped with a rubber check valve and gate valve to prevent backflow.An effluent pumping station is also available to support discharge operations and includes a submersible pump and an auxiliary pump. These components provide flexibility in managing effluent flows under varying hydraulic conditions. Sludge Management System Sludge produced through the treatment process is stabilized and stored within the facility's solids management system.This includes a primary digester and secondary digester, both equipped with diffused aeration systems and mixers.The secondary digester incorporates a decant system for supernatant management.Additional storage and handling are provided by a biosolids transfer tank and four aerated sludge holding tanks.This system supports ongoing sludge stabilization and preparation for off-site transport and disposal. Standby Power Both the collection system and the WWTP are equipped with standby power systems. Pumping stations include either permanent generators or provisions for portable generator connection, ensuring uninterrupted operation during electrical outages.The WWTP maintains emergency power capacity to support uninterrupted treatment, disinfection and effluent discharge. pg. 5 Ontario Clean Water Agency-Port Burwell WWTP& Bayham WWC 2025 Annual Performance Report System Facts: Environmental Compliance Approval #0112-B6VQV8 (issued December 6, 2018) CLI Environmental Compliance Approval #061-W601 (issued May 24, 2023) Rated Capacity 1,060m3/d Receiving Water Big Otter Creek For 2025,the Port Burwell WWTP & Bayham WWC system was operated in accordance with the provincial regulations as required in ECA#0112-B6VQV8 and #061-W601.The following report is presented such that it corresponds with Section 46(3) (a)through (n) and Schedule E condition (4).

As well, monitoring of the alum dosages and wasting volumes are completed. Data collected from these tests provide valuable information to the operators to make the appropriate adjustments in the treatment process and take corrective actions before the plant reaches its effluent limits. Calibration, Maintenance and Repair Activities The flowmeter was verified on December 1st, 2025 by Flowmetrix in accordance with the facilities ECA. The flow meters met the accuracy tolerance of within 15%of the actual flow rate. Gas detection meters were calibrated on March 5, 2025 by HETEK Solution Inc. Refer to Appendix D Calibration Reports for the 2025 calibration records. Summary of Efforts Made to Achieve Design Objectives In 2025,the Port Burwell WWTP experienced two (2) effluent objective exceedances for TSS (1),TAN (1) concentrations as well as five (5) limit exceedance for TAN(4) and E.coli (1).All exceedances were reported in accordance with MECP regulatory requirements, and corrective actions were implemented to address contributing factors and maintain compliance moving forward. Refer to Table 3 for a summary of monthly average objective and limit exceedances. Refer to Table 4 for a summary of effluent loading limit exceedances. A monthly average effluent Total Suspended Solids (TSS) concentration objective exceedance occurred in January as a result of a mechanical failure of the SBR No. 1 basin motive pump.The unit was removed from service and replaced on January 27t", 2025. A monthly average effluent Total Ammonia Nitrogen (TAN) concentration objective exceedance occurred in March, attributed to elevated flows resulting from heavy rainfall events, which caused hydraulic overloading of the treatment process, diminishing the effectiveness of biological nitrification. Monthly average effluent Total Ammonia Nitrogen (TAN) concentration limit exceedances, along with effluent loading limit exceedances, were observed in April and May, attributed to elevated flows resulting from heavy rainfall events,which caused hydraulic overloading of the treatment process, diminishing the effectiveness of biological nitrification. A monthly geometric mean effluent E. coli concentration limit exceedance occurred in June due to multiple ultraviolet (UV) disinfection degradation incidents, which were caused by reduced UV transmittance diminished the system's ability to achieve effective disinfection. Despite the WWTP's objective and limit exceedances during 2025,there were no parameters that exceeded objectives more than 50%of the time and no trends indicating deteriorating effluent quality were observed.The average plant flow volumes have not exceeded 80%of the plant's design capacity. pg. 18 Ontario Clean Water Agency-Port Burwell WWTP& Bayham WWC 2025 Annual Performance Report Table 3:Monthly average exceedances Date Parameter Concentration Objective Limit Reasoning (mg/L) (mg/L) (mg/L) Jan-2025 TSS 10.9 10 15 S13R#1 mechanical failure Mar-2025 TAN 3.5 3 5 Due to high flows from Heavy rain Apr-2025 TAN 9.0 3 5 Due to high flows from Heavy rain May-2025 TAN 4.5 1 2 Due to high flows from Heavy rain Jun-2025 E. coli 315.9 150 200 Result of multiple UV degradation Incidents Table 4:Loading limit exceedances Date Parameter Concentration Limit Reasoning (mg/L) (mg/L) Apr-2025 TAN 8.24 Apr 1-15 Due to high flows from Heavy 8.30 rain Apr-2025 TAN 3.83 April 16-30 Due to high flows from Heavy 2.16 rain Sludge Handling and Generated Sludge is pumped from the SBR basins to the aerated sludge primary and secondary digester where it is then pumped to the sludge holding tanks.

Total Hauled Sludge Volumes Complaints In 2025, community complaints were recorded in relation to odours from the Port Burwell Wastewater Treatment Plant and the sanitary collection system.The odours were identified as originating from pumping station and force main infrastructure. Corrective actions were implemented, including increased Bioxide dosing at Pump Stations No. 1, 5, and 6,to mitigate odour impacts and address the concerns. By-passes, Overflows, Spills or Abnormal Discharge Events There were no by-passes, overflows, or spills that occurred at the Port Burwell WWTP or within the Bayham Sanitary Collection System in 2025. The ECA requires additional daily sampling for the WWTP when the plant is operated outside of normal operating conditions. Results are included in monthly average final effluent monitoring results. Refer to Figure 17 for the number of days each month where the WWTP operated outside its normal operating conditions, all of which were due to precipitation events. Refer to Table 6 for a summary of all Outside Normal Operating Conditions events in 2025. pg. 20 Ontario Clean Water Agency-Port Burwell WWTP& Bayham WWC 2025 Annual Performance Report 18 16 14 — 12 — m 10 — x� 8 6 4 2 0 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Total Month #Days Raw Flow Exceeded due to Precipitation ■#Days Raw Flow Exceeded due to Maintenance I Figure 17: Number of Outside Normal Operating Condition Days per Month Table 6:Summary of Outside Normal Operating Conditions Events Date Event Description Flow(m3) January 1, 2025 High flow, over capacity 1,253 March 5, 2025 High flow, over capacity 1,561 March 6, 2025 High flow, over capacity 1,235 March 16, 2025 High flow, over capacity 1,130 March 29, 2025 High flow, over capacity 1,124 March 30, 2025 High flow, over capacity 1,154 March 31, 2025 High flow, over capacity 1,185 April 2, 2025 High flow, over capacity 1,449 April 3, 2025 High flow, over capacity 2,313 April 4, 2025 High flow, over capacity 1,448 April 5, 2025 High flow, over capacity 1,219 April 6, 2025 High flow, over capacity 1,090 April 7, 2025 High flow, over capacity 1,129 May 5, 2025 High flow, over capacity 1,260 May 6, 2025 High flow, over capacity 1,583 May 7, 2025 High flow, over capacity 1,146 December 29, 2025 High flow, over capacity 1,259 pg. 21 Ontario Clean Water Agency-Port Burwell WWTP& Bayham WWC 2025 Annual Performance Report Notice of Modifications to Sewage Works (Alterations) There were no modifications made to the Port Burwell WWTP or Sanitary Collection System in 2025. Summary of Efforts made to achieve conformance with F-5-1 The Municipality of Bayham is a separated collection system;therefore, a Pollution Prevention Control Program is not required to be established or maintained.There are six designed overflows within the collection system for the protection against basement flooding, damage to equipment/property and prevention of treatment process wash out. No overflows or bypasses have occurred in 2025. Ongoing flood preparedness efforts to mitigate flood water from entering the sanitary collection system include gasketing of sanitary manholes in low lying flood prone areas as well as sand bagging manholes when and where applicable. Notice of Modification to the Works & Purposed Works There are no changes to the schedule for the completion of construction and commissioning activities for the major processes and equipment groups in the Proposed Works.The Eden Pump Station#1 storage tank upgrades remain on track to continue throughout 2025, with final construction and commissioning still anticipated for completion in 2026. pg. 22 Ontario Clean Water Agency-Port Burwell WWTP& Bayham WWC 2025 Annual Performance Report APPENDIX A Influent & Effluent Data Port Burwell Wastewater Treatment Plant Year: 2025 Municipality of Bayham Works#: 11=1319 Population Served: 2530 Annual Compliance Summary Design Avg Flow(m): 1060 FLOWS BIOCHEMICAL 02 DEMAND SUSPENDED SOLIDS PHOSPHORUS NITROGEN SERIES EFFLUENT SEPTAGE D0c1-A 15 A r16-Nov30 Dec1- r15 A r16-Nov30 2025 Total A-Da Desl n Max Da Mon.D.11 A .Raw A .Raw Av.Eff.

This letter of transmittal confirms completion of this service project. The following service report contains the individual instrument reports for all verification/calibrations as well as an Equipment List Summary. Note:Equipment List Summary is only included where 5 or more instruments are verified/calibrated for the same client/area. Otherwise,only individual reports are provided. In addition to the base report, relevant information related to standard approach and methodologies for various instruments verified and/or calibrated, and a statement of qualifications for all verification/calibrations completed by trained, knowledgeable and experienced personnel is found in the section Quality Assurance and Quality Control. If you have any additional questions or concerns with regards to this report, please do not hesitate to contact me directly. Kind Regards, Sarah Cawston Sales&Service Coordinator 2088 Jetstream Rd London,ON N5V 3136 c. 519-281-9660 scawston@scgflowmetrix.com 2098 Jetstrearn Rd. London,ON N5V 3P6 100D Edgeley Blvd. Concord,ON FLOWMETRIX TECHNICAL SERVICES Opportunity�SYD�tb QUALITY ASSURANCE/QUALITY CONTROL Flowmetrix adheres to a rigid scope of service and deliverables for each client and instrument verified,calibrated,and reported. We follow a standard guideline while performing verification and calibration procedures for each instrument, using original equipment manufacturer(OEM)tools,where possible.The values are field reported and entered in a standard report format for client review.A digital report is completed for each instrument and collated into a single document for client record. Approach &Methodology Flowmetrix conducts verification of each instrument and subsequent calibrations on instruments that are outside the expected tolerance of the instrument response,where possible. Manufacturers OEM suggested testing guidelines are used to verify and/or calibrate each instrument. Where, unable to perform the verification or calibration as suggested by the manufacturer,a best management practice is performed to validate the performance of such instruments. REPORTING Flowmetrix report is divided into(2)sections. Section i identifies an equipment summary of all instruments verified during this service project including instruments that PASS or FAIL; section ii identifies individual equipment reports for client review and record and identifies any comments and deficiencies that should be noted for client review and possible response. Section (i) -Equipment Summary An equipment summary sheet identifying all instruments; both PASSING and FAILING verification and/or calibration while completed during this service project. The Summary Equipment List is only included where 5 or more instruments are verified/calibrated for the same client/area. Otherwise,only individual reports are provided. Section (ii)-Individual Equipment Reports Individual equipment reports are completed for easy review and are found in Appendix B.These reports outline all specific information pertaining to the equipment be tested; noted as meter under test (MUT). Date, time, location, meter make, model and serial number accompany this report for tracking and identification. Each report identifies a PASS or FAIL comment'as found' and 'as left' upon completion of the verification and/or calibration. Where possible, a verification is performed prior to calibration, if the OEM testing procedures allow, otherwise an 'as left' report is provided for such equipment. Note:If a meter under test(MUT)is(AS FOUND)to be operating outside of the allowable tolerance,the report will indicate"NA".The"NA"statement is NOT suggesting the MUT,or a component of the MUT is not functional or has failed;but simply indicates at the time the test was conducted the verification reported values are found outside the allowable tolerance. Only if the MUT is failed due to equipment failure and not verification/calibration tolerances,the report will indicate"FAIL"(AS FOUND)and will be commented on in the individual equipment report. STATEMENT OF QUALIFICATIONS To comply with our clients DWQMS standards, Flowmetrix adheres to a rigid approach to conducting our equipment verification/calibration services including the training received by our company and our personnel conducting service. A Statement of Qualifications outlining Flowmetrix qualifications to conduct this level of service is available in a separate document upon request. 1:: Jetstream Rd.
