Via Video Conference (Approval Pending) 1. Call Meeting to Order Chairperson Denise Bhirdo called the Sewer and Water Utilities meeting to order on Tuesday, March 10, 2026, at 1:00 PM. 2. Roll Call A roll call was conducted, with the following members present: Chairperson Denise Bhirdo and members Nate Bell, and Kurt Harff Staff present: Utilities Director Megan Barnes, Village Administrator Ben Andrews, Utilities Clerk Kara Kroll Others: Chad Olsen 3. Approval of Agenda Motion by Bell, second by Harff to approve the agenda as presented. Motion carried – all ayes. 4. Approval of Minutes of the February 10, 2026 Meeting, As Published Motion by Bell, second by Harff to approve the minutes of the February 10, 2026 meeting as presented. Motion carried – all ayes. 5. Comments, Correspondence and Concerns from the Public There were no members of the public present and no correspondence to report. 6. Discussion/Action Items a. Facilities Study Discussion and Recommendation Utilities Director Megan Barnes presented the three options from the facility study for addressing biosolids management: Option 1 - construct a sludge drying facility ($17.8 million), Option 2 - construct a reed bed system, and Option 3 - continue hauling to Sturgeon Bay with potential future requirements for onsite storage tanks. Chair Bhirdo expressed support for exploring regional cooperation with other municipalities for the sludge drying facility, stating that if Sister Bay were to proceed alone, reed beds would make more sense, if multiple communities could participate, the dryer option would be preferable despite the higher cost. Bell agreed that reed beds were the practical choice for Sister Bay alone, though he acknowledged the sludge dryer would be "cooler" if cost were no object. He expressed concern about the complexity of Minutes for the March 10, 2026 meeting of the Utilities- SWUC Committee- Unapproved Version coordinating multiple municipalities but supported pursuing regional discussions with a defined timeline. Administrator Andrews reported that he had reached out to administrators and operators in Ephraim, Fish Creek, and Baileys Harbor, with most indicating willingness to have conversations about regional cooperation. He noted that such an arrangement would require long-term commitments, typically 15-20 years, to cover expenses. Barnes confirmed that Ephraim, Fish Creek, and Baileys Harbor had expressed interest in discussions. She noted these communities had received similar reed bed recommendations in their own facility studies, and Ephraim was particularly interested because they had not received principal and forgiveness for their planned upgrades and believed regional cooperation might improve their chances of receiving such funding. The committee discussed setting a six-month timeline for regional discussions, after which they would proceed with reed beds if no agreement could be reached. Barnes confirmed she had been sharing cost estimates of approximately $15-17.8 million with the other communities. Consultant Chad Olsen identified the West Central Wisconsin Biosolids Facility near River Falls as an example of regional sludge processing that has operated for at least a decade. Motion by Bell, second by Harff to adopt the facility study. Motion carried – all ayes. The committee agreed to pursue regional discussions for the sludge drying facility while maintaining reed beds as the fallback option if Sister Bay proceeds alone. This item will be placed on the March board meeting agenda for discussion. b. Non-Potable Reuse System - Expansion Tanks WWTP Barnes reported that the expansion tanks for the non-potable reuse system have ruptured bladders that cannot be repaired because replacement parts are no longer manufactured. She presented a quote of $19,180 for complete replacement of both tanks, with a six-week lead time. The expense would come from replacement funds. The committee discussed whether board approval was necessary given the lead time, with Andrews and Barnes concluding that while some emergency repairs could proceed without board approval, this repair could wait for formal approval. Motion by Bhirdo, second by Harff to recommend the quotation for replacement of the two expansion tanks as presented to the Village Board for approval. Motion carried with Bell opposed. c. Wastewater Treatment Plant Operations Report Barnes provided an update on the ongoing ice issues in the sludge storage tank, explaining that the plant has been battling thick ice accumulation for three weeks. The cold weather caused more ice formation than usual, and ice formed over aeration spots, increasing pressure and apparently breaking a coupling between the main diffuser line and diffuser arms. She explained that this is a periodic issue due to the uncovered sludge tank, though this year's accumulation was more severe. The plant is currently using the sludge loadout pump as a mixer and has had a company jet hot water into the empty storage tank to remove ice. The tank switch should occur early the following week once the remaining ice is cleared. 7. Matters to be placed on a future agenda or referred to a committee, official, or employee The facility study discussion and regional cooperation efforts will be placed on the March Village Board meeting agenda. Minutes for the March 10, 2026 meeting of the Utilities- SWUC Committee- Unapproved Version 8. Adjournment Motion by Bhirdo, second by Bell to adjourn at 1:32 PM. Motion carried – all ayes. The next meeting of the Sewer and Water Committee will be conducted at 1:00 P.M. on Tuesday April 14, 2026 via Video Conference. Respectfully Submitted, Kara Kroll Utilities Clerk Page 1 STAFF REPORT Date: July 14, 2026 To: Sewer and Water Utility Committee Re: Sludge Storage Tank Aeration System Replacement Author(s): Megan Barnes, Utilities Director Action(s) Requested: ☐ Ordinance ☐ Resolution ☒ Motion ☐ Receive/File POLICY ISSUE(S) “Should the Sewer and Water Utility Committee recommend to the Village Board for approval, the unbudgeted expense of the sludge storage tank coarse bubble diffuser system replacement.” BACKGROUND INFORMATION The coarse bubble diffuser system that is suspended above the base of the sludge storage tank sustained significant ice damage this past winter. When the damage was first discovered, ice was still present, so the extent of the damage was unknown. Once the damage was noticed, operators changed the valving to allow for additional mixing utilizing the sludge loadout pump and mixing nozzles, which also helped melt the ice shelf that was present in the sludge tank. After the ice completely thawed, operators were able to transfer the sludge from the sludge tank we typically use, to the back-up sludge storage tank. Operators cleaned up the tank and photographs of the aeration system damage were sent to contractors for a quotation. August Winter & Sons originally installed the coarse bubble diffuser system equipment in the sludge storage tank in 2004. The spare sludge storage tank is smaller than the sludge storage tank we typically use, so the repair is necessary as soon as possible in order resume to regular operation. While the tank is down our sludge storage volume is substantially decreased. PRIOR ACTION/REVIEW The sludge tank aeration system damage was noticed by operators in February of 2026. The damage was evident, but the extent unknown, due to an uneven aeration pattern in the sludge storage tank. Operators decided to switch the valving to allow the sludge load out pump and mixing nozzles to function as an additional mixer in the sludge storage tank until the ice shelf thawed. Operators were able to transfer the sludge from the tank with the damaged aeration to the spare tank in late April. Page 2 FINANCIAL INFORMATION If the coarse air diffusion system replacement were approved, the following funding option would be utilized: 1. WWTP Replacement Funds RECOMMENDED ACTION(S) Village staff recommends that the cost of the coarse air diffuser system replacement in the sludge storage tank be approved. If the Village Board were in favor of this policy action, the following motion may be made: “I move to recommend the quotation for the replacement of the coarse air diffuser system as presented to the Village Board for approval.” POLICY ALTERNATIVE(S) The Village Board could take the following actions: • Approve with modifications “I move to approve the quotation for the replacement of the coarse air diffuser system in the sludge storage tank with the modification of [List Modification Sought]. • Deny “ I move to reject the quotation for the replacement of the coarse air diffuser system in the sludge storage tank and take no further action at this time.” • Table “ I move to postpone action on the quotation for the replacement of the coarse air diffuser system in the sludge storage tank and direct staff to return to the SWUC with additional information regarding [List Information Sought] at a future meeting.” ATTACHMENT(S) 1.

The Forgiveness of Sewer Charges / Leak Adjustment Policy is not a Wisconsin Administrative Code, Chapter PSC 185 requirement. However, there have been a few cases in which residents have experienced exterior leaks and have requested a sewer charge leak adjustment due to the water not entering the sanitary sewer system. The Utility has never had a sewer leak credit policy in effect, so requests in the past have been denied. RECOMMENDED ACTION(S) Village staff recommends that the Sewer and Water Utilities Committee recommend for Village Board approval and resolution the following policies; ➢ Disconnection Policy ➢ Deferred Payment Policy ➢ Tax Certification Policy ➢ Forgiveness of Sewer Charges / Leak Adjustment Policy Page 2 If the Sewer and Water Utilities Committee were in favor of this policy action, the following motion may be made: “I move to recommend for Village Board approval and resolution the [Policy Name] as presented” POLICY ALTERNATIVE(S) The Sewer and Water Utilities Committee could take the following actions: • Approve with modifications. “I move to recommend for Village Board approval and resolution the [Policy Name] with the modification of [List Modification Sought].” • Deny “I move to reject the [Policy Name] and take no further action at this time.” • Table “I move to postpone action on the [Policy Name] and direct staff to return to the SWUC with additional information regarding [List Information Sought] at a future meeting.” ATTACHMENT(S) 1.

PURPOSE The purpose of this policy is to establish guidelines for entering into Deferred Payment Agreements (DPA) for the payment of past-due utility balances. The Utility is required to offer a DPA to residential customers and may offer a DPA to commercial customers but is not required to do so. 2. STATE LAW Wisconsin Admin Code § PSC 185.38 requires utilities to offer a DPA to residential customers who are unable to pay their bills in full. Delinquent amounts paid according to the terms of an established DPA are not subject to late charges and cannot be levied as a tax against the lot or parcel of real estate to which the utility service was furnished. 3. TERMS A DPA consists of two elements: 1. A reasonable down payment; and 2. An installment plan to pay the remaining outstanding balance over a specified period of time. A customer with a DPA is required to pay their current charges in full in addition to the agreed- upon installment payment. The Utility must receive payment on or before the due date. Delinquent amounts paid according to the terms of an established DPA are not subject to late charges. 4. DEFAULT A late or missed payment will cause the DPA to “default ,” placing the customer in jeopardy of disconnection. If a customer defaults on a DPA and there has not been a significant change in the customer’s ability to pay since the agreement was negotiated, the utility is not required to offer another DPA prior to disconnection.

Page 1 Forgiveness of Sewer Charges / Leak Adjustment Policy UTILITIES-POL-2026-004 Adoption: RES. 2026-005 Department: Utilities Effective Date: MM/DD/YYYY Revision Date: N/A Policy Source: Sewer and Water Utilities Committee Policy Audience: Utility Users; Sister Bay Water and Sewer Utilities 1. PURPOSE The purpose of this policy is to establish guidelines that are to be followed in a uniform manner, exercised consistently, and in accordance with the Forgiveness of Sewer Charges / Leak Adjustment Policy. 2. POLICY The Village of Sister Bay Utilities Department is responsible for the maintenance and operation of the water distribution system and sanitary sewer collection system. Each property owner is responsible for the installation, maintenance and any repairs of water piping from, and including, the curb stop to the main building and all wastewater piping from the connection to the service lateral to the main building and all plumbing inside the building. The Village of Sister Bay’s Policy for Forgiveness of Sewer Charges / Leak Adjustment Policy is intended to address high use utility bills caused by water pipe breaks or failures, that are beyond the control of the customer. It is the responsibility of the customer to ensure that all plumbing, fixtures, and appliances in their building are maintained in sufficient operating condition using best common practices to ensure their proper functionality. It is not the intent of this policy to issue credits for failures resulting from lack of maintenance. All water that passes through the water meter must be paid for, therefore leak credits will only be considered on the sewer use portion of the utility bill. The Village of Sister Bay will consider sewer credits on a case-by-case basis. Sewage credits will be awarded in the form of a credit applied to the sewer customer account. Refunds by check will only be made when an account is closed and the customer has a credit balance remaining on the account. A sewer credit may only be considered if usage is at least 150% above the customer’s average usage determined by the previous quarterly billing cycles on record. Any eligible credit for sewer use will be calculated by subtracting the average water usage from previous like quarter(s) from the quarter in which the credit is being applied for. In instances where a customer has occupied or owned the property for less than one year, the average of previous quarters will be used. If a Village of Sister Bay Leak Adjustment Policy Page 2 customer does not have any history of accurate verified readings, estimated or prorated usage cannot be used to calculate the credit and the customer will not be eligible for a credit. 3. APPLICABILITY Sewer credit can be applied for in the following circumstances; Outdoor Water Leak Credit Sewer credits may be considered for excess water usage resulting from a leak that occurred outside the building if the customer can prove that the water that was leaked did not enter the sanitary sewer system. It will be the burden of the customer to provide adequate proof to justify the claimed application. • Sewer credits will not be considered for excess water usage resulting from one or more of the following; lawn watering, pool filling, car washing, ice rink flooding Sewer credit will not be considered in the following circumstances; Indoor Water Leak Credit No credits for sewer use will be approved for leaks inside a building if the leaked water entered the sanitary sewer system via any fixture, appliance, or drain. Sewer use credits for indoor water leaks will only be approved if the customer can provide enough evidence that the water that was leaked did not enter the sewer system. It will be the burden of the customer to provide adequate proof to justify the claimed application. Examples of circumstances in which sewer credit will not be considered; ➢ Customer failed to make repairs to a pipe, appliance, or fixture known to have defects or be in need of repair. ➢ High usage occurred more than 30 days after customer received a high bill or high usage notice form the Sister Bay Utilities Department. ➢ Customer is unwilling to allow Utility staff access or entry to inspect the reported leak and/or repairs made. ➢ High usage is due to failure to turn off hoses, sprinklers or sprinkler systems. ➢ High usage is due to negligent water use or other incident within the customer’s control. ➢ High usage is due to watering lawns, trees, or gardens. ➢ High usage is due to failure to turn off sprinklers, hoses, or sprinkler systems. ➢ The customer has an outstanding delinquent balance. (Submit payment for delinquent balance or sign a deferred payment agreement prior to requesting adjustment). Village of Sister Bay Leak Adjustment Policy Page 3 ➢ The customer was granted an adjustment to their sewer usage utility bill within the last 24 months at a specific location (adjustments may be granted to same customer at other locations). 4. APPLICATION PROCESS A fully completed Request for Forgiveness of Sewer Charges / Leak Adjustment form must be submitted to the Utility for a credit to be considered. Customers must submit applications to the Utility Clerk within 30 days of the billing date where the excessive use was included. It is strongly suggested that the customer pay at least the amount of an “average” bill and continue to pay subsequent bills during the time the application for adjustment is under review. Applicants are required to provide proof of repair at the time of application (e.g., receipts for materials or services related to that repair). Credits for leaks that are repaired more than 30 days after a high use billing issuance will not be considered. Applications can be found on the Village website at: https://sisterbaywi.gov/applications/ or at the Wastewater Treatment Plant located at: 2124 Autumn Ct, Sister Bay, WI 54234. Applications can be submitted via email to kara.kroll@sisterbaywi.gov, or in person. All applications will be reviewed by the Utilities Director and a determination made within 30 days of application submittal. The Utilities Director or Utility Clerk will notify the applicant of the Utilities Directors decision. If the case is determined to be eligible for a leak adjustment, the adjustment will be applied to the next billing cycle. All sewer credit requests in excess of $1000.00 must be approved by the Village Finance Committee prior to issuance. Customers will be notified of this situation and when the secondary review is scheduled to take place. Customers who do not agree with the Director’s determination regarding their application have the right to appeal their application to the Sewer and Water Utility Committee for further review within 20 days of the date that the initial determination is issued. 5. ADJUSTMENT TERMS – CALCULATION OF CREDIT Water Usage Charge The Public Service Commission of Wisconsin requires customers to pay at least the cost of the Utility providing the water that was lost due to a leak. Water charges will not be reduced in the event of a leak. Village of Sister Bay Leak Adjustment Policy Page 4 Sewer Usage Charges In cases where a customer shows sufficient evidence to the committee that all water usage during a leak was not discharged to the sanitary sewer system, full credit of the sewer usage charges above the customer’s average usage will be considered. If the customer does not have a history of accurate verified water reads, estimated readings cannot be used to calculate sewer credits and the customer would not be eligible for credit. In cases where water usage during a leak was not discharged to the sanitary sewer system, an adjustment of sewer usage charges above the customer’s average usage will be considered with limitation to the number of adjustments allowed during the customer’s tenancy and/or ownership of the property during a ten-year period as follows: First occurrence Eligible for adjustment of 100% of sewer usage. Second occurrence Eligible for adjustment of 75% of sewer usage. Third occurrence Eligible for adjustment of 50% of sewer usage. Fourth and subsequent occurrences Not eligible for adjustment of sewer usage. Please note that leak adjustment applications are subject to the Applicability section above and a recurring plumbing or appliance leak is not eligible for multiple leak adjustments where the customer failed to make necessary repairs to prevent the leak from recurring.

I understand and accept that significant water usage occurred during this period. My request is not to dispute water consumption itself, but to request removal or adjustment of sewer charges associated with this usage due to the nature and location of water discharge. 1. Summary of Event During a period of extreme winter conditions following Winter Storm Elsa, my property in Sister Bay was inaccessible due to a substantial snow barrier (approximately 12 feet of plowed snow blocking access). No occupancy or routine property use occurred during the majority of this time. Beginning March 16th, an exterior water hose was unintentionally left in a partially open position during this period, resulting in continuous outdoor water discharge. I am still unclear how it was turned on, as Sister Bay had plowed a 12 foot wall of snow in front of our property – nobody could even enter the property for over a week. (handle is very loose – could have been ice/snow). 2. Physical Conditions and Access Limitations - Property was inaccessible due to heavy snowfall and plowed snow accumulation - No routine presence at the property during the majority of the billing period - Access to exterior fixtures was not practical during the initial portion of the event period 3. Known Property Activity Timeline - March 28: I visited the property to address snow removal and observed water-related issues in the basement. At that time, I did not identify the exterior hose as the source. - April 2–5: A planned rental stay occurred. Guests documented water intrusion in the basement during their stay. - April 6: I returned to the property and discovered the exterior hose was on. I confirmed a steady flow rate of approximately 2.2 gallons per minute using a measured bucket test. 4. Measured Water Use A controlled flow test performed at the same setting as observed at discovery indicates: - Flow rate: approximately 1.8–2.7 gallons per minute - Estimated total usage over the billing period: approximately 55,000–80,000 gallons 5. Sewer Charge Dispute The water discharged during this event was entirely outdoor and did not enter the sanitary sewer system. Because sewer billing is typically based on assumed return flow, I respectfully request: - Removal of sewer charges associated with this usage period, or - Adjustment to reflect non-sewer outdoor water use classification Supporting Documentation Available I can provide: - Timestamped photographs and video of the massive puddling of water in the back of the house - Guest communication documenting basement water intrusion - Rental occupancy records - Snow and access condition evidence - Flow rate measurement documentation 7. Request I am requesting a formal review of this case and an adjustment of sewer charges based on the documented nature of water use and discharge. I am not requesting policy changes or exemptions outside of standard utility practice, only accurate classification of water that did not enter the sewer system. Sincerely, Walter Nawrot 920-268-5512 Outlook Request to Appear on Board Agenda – Water/Sewer Billing Dispute FromWalter Nawrot <wnawrot1@gmail.com> Date Tue 4/14/2026 11:37 PM To Kara Kroll <kara.kroll@sisterbaywi.gov> 1 attachment (15 KB) Request for Review of Sewer Charges.docx; Dear Board President and Members of the Water Utility Board, I am requesting placement on the agenda for an upcoming board meeting to review and present a billing dispute regarding my property in Sister Bay. This is not a general complaint about water usage. I am requesting a formal review of sewer charges applied to a documented case of outdoor, non-sewer water use under unusual access and weather conditions. I would like the opportunity to present a clear timeline, supporting documentation, and measured flow data that I believe are relevant to how the usage has been classified and billed. I understand the utility’s current policy structure regarding limited exceptions. My request is not to disregard policy, but to ensure the classification of this specific usage (water vs. sewer return) is accurately applied based on physical facts. Please advise the process for placement on the next available board agenda. I am prepared to provide all supporting documentation in advance or at the meeting.

Review of Financial Statements See the attached financial reports. Well Permit Status Report 2026 well permit status; see enclosed information. WPDES Permit Renewal The current Wisconsin Pollutant Discharge Elimination System Permit (WPDES) for the wastewater treatment facility will expire on December 31, 2026. Barnes has finalized and submitted the 2026 Village of Sister Bay wastewater treatment facilities WPDES application and all necessary documentation to the Department of Natural Resources (DNR). The WPDES application was completed and submitted on July 2, 2026. A copy of the WPDES Renewal is included in the packet for review. It is important to note that the reissued permit may impose further limitations on the discharge of pollutants and may include a schedule of compliance for construction or other steps that are necessary to meet any such limitations. Chemical Standard Operating Procedure As part of the Wisconsin Pollutant Discharge Elimination System Permit (WPDES) reissuance for the wastewater treatment facility, the Department of Natural Resources (DNR) highly recommended that the Village develop and submit to the DNR a Standard Operating Procedure (SOP) for the Chemical Phosphorus Removal System. The SOP provides guidance for operators regarding the operation of the chemical feed system to reduce potential overdosing of phosphorus treatment chemicals. Submitting an acceptable SOP will hopefully reduce the potential for more frequent whole effluent toxicity (WET) monitoring being added to the reissued permit. The Village of Sister Bay’s Chemical Phosphorus Removal System SOP was submitted to the DNR on July 2, 2026. Notice was received on July 6, 2026, that the Department of Natural Resources (DNR) has completed the review of the Standard Operating Procedure (SOP) for the Chemical Phosphorus Removal System for the Sister Bay Wastewater Treatment Facility. The DNR approved the SOP. Sister Bay must operate in conformance with this SOP effective immediately. If Sister Bay wishes to operate differently than specified in the approved SOP or make significant changes to the SOP, a written request must be submitted to the department for approval to amend the SOP. 2025 CMAR The 2025 Compliance Maintenance Annual Report (CMAR) for the Sister Bay Wastewater Treatment Facility has been submitted and reviewed by the Department of Natural Resources (DNR). A copy of the DNR Response to Resolution or Owner’s Statement is included in the packet for review. DATCP Lab Audit Barnes has scheduled the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) biennial water laboratory evaluation for July 20, 2026. The audit is required for the laboratory’s license to utilize the Colilert bacteriological analysis method. 2026 Drinking Water System Routine Monitoring Sister Bay Waterworks has sent in the samples required for analysis to satisfy the Department of Natural Resources (DNR) Drinking Water System Routine Monitoring Requirements. Sister Bay Waterworks has sent in samples for the Inorganics, Radioactivity, and Volatile Organics requirement. The Disinfection Byproducts (TTHM, HAA5) samples will be sent in on July 21, 2026, along with a portion of the ten required Lead and Copper samples. Pretreatment Fine Screen and PLC Issues On May 26, 2026, Operators noticed that the pretreatment fine screen was no longer operating. Operators could run the fine screen in hand, but the equipment would not work through the Programmable Logic Controller (PLC) automated programming. That same day, while Operators were trying to diagnose the fine screen issue, the pretreatment PLC dropped all communication. Barnes and IPS technicians worked on reviving the PLC, but all efforts were unsuccessful. Without the PLC, all equipment in pretreatment could only be operated manually. Barnes expedited the purchase of a new PLC through Werner and had the pretreatment PLC replaced and reprogrammed on May 27, 2026. After the PLC was replaced, the fine screen was still not operational. Barnes and the IPS technicians found a work around that worked for about two weeks while trying to diagnose the issue. The fix ultimately failed and Action Electric was called to help us find the electrical issue. With the help of Action Electric and the IPS technicians, Operators isolated an electrical short that was occurring in a conduit line where the fine screen electrical runs. Action Electric repaired the issue, and the fine screen and pretreatment PLC have had no further issues. Sludge Hauling Update NEW Water is temporarily shut down for sludge hauling due to one of their digestors being temporarily shut down for maintenance. The NEW Water incinerator will also be temporarily shut down this fall for its routine maintenance. NEW Water communicated that we are not completely cut off during the outages which will run from 06/22/2026-09/30/2026. However, they did request that we limit sludge brought to them during this time period. Barnes coordinated extra hauling in order to prepare for the outage. We are sitting in a very good position to continue holding all sludge hauling until the NEW Water outage is over. Septage Chopper Pump Plug On June 9, 2026, Operators noticed that the two septage chopper pumps were not pumping at a usual rate. We utilize the chopper pumps to lift the hauled waste from the receiving tank over to our pretreatment channel. Operators attempted to clear the check valves and pull the pumps to remove the plugs lodged inside them. Haulers were told that the hauled waste receiving station was shut down and Operators tried for two days to loosen the plug in at least one of the pumps. We were successful in getting the plug out of chopper 2, the plug was entirely comprised of “flushable” wipes. However, the plug in the pump was only half of the issue. Once we got the pump reinstalled, we determined that the discharge pipe was also completely plugged. Great Lakes TV and Seal were able to respond with their vacuum truck to assist. The Great Lakes TV and Seal crew were able to jet the discharge lines from the bottom of the tank and completely remove the “flushable” wipe plugs that was also located in the discharge lines. PFAs General WPDES Permit The WI Department of Natural Resources has determined that Sister Bay Wastewater Treatment Facility is eligible for coverage and is hereby authorized under the “PFAS Monitoring for Sewage Sludge (Biosolids) Generators” Wisconsin Pollutant Discharge Elimination System (WPDES) General Permit No. WI-0012345-01. This general permit has been developed as a supplemental permit to our WPDES individual permit. The general permit coverage begins on July 1, 2026.

Stats., and ch. NR 200, Wis. Adm. Code. Failure to provide the requested information may result in fines, forfeitures or other penalties pursuant to ss. 283.89 and 283.91, Wis. Stats. Personally identifiable information is not likely to be used by the Department of Natural Resources (DNR) for any purpose other than the reasons stated in the form or for the purpose the form is being submitted. You must use this form (or a department-approved modification to this form) to apply for an initial permit or a reissued permit for a discharge that the DNR determines requires an individual permit under ss. NR 200.03(1)(a), (b) and (c), Wis. Adm. Code. • Initial permit - If you are applying for an initial permit, s. NR 200.05(3), Wis. Adm. Code, requires that you file a complete application with the DNR no later than 180 days prior to the date you intend to commence discharging. • Reissued permit - If you have an existing permit and wish to continue to discharge after expiration of the permit, s. NR 200.06, Wis. Adm. Code, requires that you must file a complete application with the DNR no later than 180 days prior to the current permit expiration date. The application for a given permittee consists of a number of sections that may differ from another pemittee's application, based on whether your facility is municipal or industrial and based on the discharge type (surface water, land treatment, land application). You must answer every question in the sections that apply to your facility. If you try to submit the application with required fields missing or inappropriate information, an error message will alert you. You may then go back and supply the required information. For certain outfalls (all surface water and industrial land treatment and land application), effluent monitoring for a list of pollutants is required as part of the application. Please plan accordingly so results are available to submit with the application by 180 days before the deadline. The DNR may contact you for additional information that is either missing from the submitted application, or was not specifically requested in this application. Some pollutants require multiple tests and you may be required to provide attachments to your application, including documentation on additives used at your facility. Your application will not be considered complete until the DNR receives the results of all required tests and all additional documentation as requested within the application and by department staff. To begin, check to see if the Permittee and the Facility name shown at the top of the title page are correct. If the facility name and permittee name are not correct, please use the 'contact us' button in the menu bar at the left of the opening screen to report the error. If changes occurred at your facility since the last time the DNR reissued your permit and the DNR was not informed, this application may not contain all of the correct sections or outfalls. When you open the application for your facility, the correct discharge type(s) should appear in the menu bar. Outfalls for your facility will be listed under permit sections named for the type of discharged occurring at each outfall. To view individual outfalls, click on the permit section names. A bulleted list of outfalls included in each section will appear as the section headings are clicked. If the proper sections or outfalls are not given, notify the DNR of changes needed using the 'contact us' button prior to filling out the application. We will make the necessary changes and notify you when the application has been re-tailored to your facility. Any information entered in the application prior to re-tailoring will be lost when the application is released back to you with the correct sections and outfalls so it is important to make sure the application includes the correct sections and information prior to filling out any sections. If the information in your application is correct: • Click on the various sections in the menu bar to the left, one at a time, and complete the information requested by checking boxes, clicking buttons, or entering words and numbers as requested. • If you are unsure on the information needed for specific questions, click on the Instructions button on the left menu bar. This instruction document will open to the section you are working on. Useful tip: After you bring up the instructions, you may print them. Set the print job to only print the pages you’d like printed, otherwise the complete 40-page instruction document will print. • At certain points in the process, you may be requested to save. Your work will automatically be saved upon exiting but we recommend using the save button before you exit a section and frequently between questions to prevent data loss in the event of a computer system crash or network drop. You may complete some parts of the application, log out of the system and come back at another time to finish. • When filling out special forms, the save button in the left menu bar will be disabled. Prior to closing out any special forms, save the information entered using the save button provided at the bottom of the form. • You may print a section or multiple sections at any time by using the print button in the left menu bar. This will allow you to select what you want to print, open a PDF file and print pages using normal printing procedures you use for any other PDF document. You may also save a copy of your application using this print button. To get back to the application program, close the PDF application and select 'cancel' in the print window. • When you believe a section is complete, click on the validate button in the left menu bar. If information is missing, a message will tell you what needs to be completed still. Once all the required information for that section has been supplied, a red check mark will appear in the left menu bar next to the section. You may change your answer to a question in a validated section up until you submit your application. After you change an answer in a validated section, you must save and re-validate. • When all sections are complete, as indicated by red check marks next to the sections, the Authorized Representative will use the submit button to send the application to the DNR. When the Authorized Representative clicks on the submit button, they will see a box stating they believe the application is complete and accurate and warning them that they will no longer be able to make changes. Clicking OK will bring up a Certification Statement page and send a 'finalize submission' email with a certification code to the facility's Authorized Representative, whose email should be listed on the certification page. • To receive the certification code, the Authorized Representative must make sure WTeReports@wisconsin.gov isn’t blocked by their spam filter. If they do not receive the email to finalize submission, they should double check the email address listed in the certification page and look for an email from WTeReports@wisconsin.gov in the junk mail folder for the listed email address. • To certify the application, the code received via the 'finalize submission' email will need to be entered in the box included on the certification page. • Once the permit is certified, an automated email will be sent to the facility's Authorized Representative and the facility owner (when applicable). Instructions for submitting additional documents and attachments to the application will be included in this automated email along with instructions for viewing, printing and saving the final, certified application.

WPDES Permit Application SISTER BAY WASTEWATER TREATMENT FACILITY Last Updated: Permit No: 07/02/2026 0022071-11-0 Potential WWTP upgrade to implement one of the biosolids handling options outlined in the completed Wastewater Treatment Facility Facility Assessment, Feasibility Study & Long-Term Facility Planning Engineering Report compiled by McMahon Associates, Inc. The two options presented in the report that would require Sister Bay to install new equipment are a regional biosolids facility (sludge dryer) and reed beds. Other upgrades were also included in the report as consideration items for updating the following: equalization tank aeration/mixing system, the orbal oxidation ditch aeration system, secondary clarifier and effluent reuse pumping. Equalization tank aeration: Option 1- Add a second set of coarse bubble diffusers to mix the lower section of the tank. Option 2- Compressed gas mixing system (preferred because it could be mounted to the floor of the tank, we would not have to reach a certain tank level before being able to aerate). Orbal oxidation ditch aeration: Option 1-Surface aerators Option 2-Fine bubble diffusers with submersible mixers Secondary clarifiers: Add second WAS pump to allow us to operate both clarifiers in the summer months and to provide redundancy. Also add an aluminum dome cover to reduce algae growth and to prepare for potential winter operation in the future as well. No. (continue to 3) 3. Design Flow Based on information available to the Department, the wastewater treatment facilities average flow (may also be known as the "dry weather design flow") is shown below. This is the flow that the Department uses for most of the effluent limit calculations. The Department will determine other needed flow values from our records. Please indicate if you agree or disagree with the average design flow given. If you disagree, please briefly explain your reason. Average Design Flow .356 MGD (million gallons per day) I agree that the given flow is correct. I disagree for the following reason: Based on the seasonality of the Village. Our two biggest months for flow is typically July and August. In 2025, the average MGD for July and August was 0.311 MGD. Our max flow day for 2025 was 07/25/2025, with 0.4217 MG. NOTE: Contact your DNR representative regarding development of an industrial pretreatment program if your Average Design Flow exceeds 5 MGD or will do so in the next 5 years. 4.

Exceptions to these requirements can be made when the Department determines that disinfection is not required to protect the recreational use. The following questions gather information that the permittee is required to identify in their permit application and that the Department must use to determine the need for effluent disinfection. 001-10.1 Proximity of the wastewater outfall to recreational activities in or on the water outside of the default recreation season (May – October). Activities that should be considered recreational activities for the purposes of this evaluation are those where people are expected to have the potential for full or partial body contact. These activities include: swimming, diving, water skiing, jet skiing, canoeing, kayaking, tubing, polar plunges, water play by children, wading for fishing or hunting, or similar activities where immersion or ingestion (accidental or otherwise) can occur. (Provide answer to 10.1.1 or 10.1.2, depending on discharge location.) WPDES Permit Application SISTER BAY WASTEWATER TREATMENT FACILITY Last Updated: Permit No: 07/02/2026 0022071-11-0 001-10.1.1 If a nonflowing waterbody: Are there recreational activities occurring between November – April within a radius of 5 miles of the wastewater outfall? Yes No Not Applicable Unknown 001-10.1.2 If a flowing waterbody: Are there recreational activities occurring between November – April within 20 miles downstream of the outfall? Yes No Not Applicable Unknown 001-10.1.3 During what months are these activities occurring? 001-10.2 The detention time of the wastewater treatment system. Except in extenuating circumstances, the discharge of wastewater to surface water from a treatment system with a detention time of 180 days or longer does not pose a risk to human and animal health. Department staff will evaluate the last permit term’s worth of flow data to determine whether or not detention times are met. 001-10.2.1 Does the current treatment process consist of treatment lagoons? Yes (proceed with answering 10.2.2 and 10.2.3) No 001-10.2.2 What is the total operating pond volume of the facility? 001-10.2.3 Are there any other influent flows not accounted for in the daily flow results on the discharge monitoring reports (i.e. hauled in waste.)? Yes (provide explanation and supporting documentation with the permit application) No 001-10.2.4 Is sufficient monitoring data available for E. coli in effluent? Monitoring data is needed for a minimum of 1x weekly samples for one disinfection season (May 1 through September 30) to be deemed sufficient. Yes, effluent results were reported on eDMRs and are representative of current operation. (If monitoring data was provided on eDMRs during the permit term, it does not need to be repeated in the permit application.) Yes, effluent sampling was conducted during the last permit term but not reported on eDMRs. (All monitoring data not provided on eDMRs shall be submitted with the permit application.) No, effluent sampling was not conducted during last permit term. No, available effluent data is not sufficient or not representative of current operation. 001-10.3 Do you have other information that should be considered when determining if there is a risk posed to human and animal health by the discharge of wastewater that has not been disinfected? Yes (If the permittee believes that there is site-specific information that the Department should consider when making disinfection-related decisions that information shall be submitted with their permit application.) No 001-11.

Discharge Monitoring Reporting (DMR) Information Select one and give details, if appropriate. This is a first-time permit application for an outfall that does not yet have a discharge. I believe that data previously reported on DMRs for this outfall for the last 36 months are representative of the effluent quality. Certain portions of the data previously reported on DMRs for this outfall for the last 36 months are not representative of the effluent quality. The data (give specific dates or date ranges) and the reasons for them not being representative are as follows: 001-13. Additive Totals Provide the number of biocides, water quality conditioners and process additives that you add to the waters discharged from this outfall. If zero, enter 0. 0 Biocides (chlorine and other halogens, fungicides, algicides, herbicides, bacterial control chemicals, etc.) 0 How many of the biocides are used less frequently than once in any four day period? 1 Water Quality Conditioners (water and wastewater treatment chemicals including scale and corrosion inhibitors, chemical conditioning agents, pH adjustment chemicals, dechlorination chemicals, alum, ferric chloride, ferrous sulfate or chloride polymers, ammonia, phosphorus, defoamers, etc.) 0 How many of the water quality conditioners are used less frequently than once in any four day period? 0 Process additives (dyes, non-biocide cleaners, surfactant-based detergents, etc.) 0 How many of the process additives are used less frequently than once in any four day period? Out of the additives included above, submit the most recent available SDS, an additive review worksheet, and the additives grid (Item 13.) for all additives which: (1) may enter a surface water without receiving treatment; or (2) are used in a treatment process, are not expected to be removed by wastewater treatment, and may contribute to effluent toxicity Exception: No SDS or additive review worksheet is required for additives solely comprised of chlorine, caustic soda (sodium hydroxide), hypochlorite, sulfuric acid, or hydrochloric acid. However, these additives should be included on the additive grid. 001-14. Additives WPDES Permit Application SISTER BAY WASTEWATER TREATMENT FACILITY Last Updated: Permit No: 07/02/2026 0022071-11-0 Fill out the additives grid at the bottom of this item for all additives associated with the discharge. An additive review is necessary for substances that may enter surface water without receiving wastewater treatment or substances that are used in a treatment process but are not expected to be removed by wastewater treatment and may contribute to effluent toxicity. Chemicals used in an industrial process generating wastewater that eventually receives treatment or chemicals added as part of a wastewater treatment process (such as ferric chloride, alum or pickle liquor) do not require an additive review. For each additive which may be present in the discharge: • Submit a copy of the 'Additive Review Worksheet' by submiting a copy with application • Submit the most recent available SDS by submiting a copy with application attachments. Examples of water treatment additives include biocides such as microbicides, fungicides, molluscicides, etc. and water quality conditioners such as scale and corrosion inhibitors, pH adjustment chemicals, oxygen scavengers, conditioning agents, water softening compounds, etc. An SDS and the Additive Review Worksheet are not required for additives with active ingredients consisting only of chlorine, hypochlorite, sulfuric acid, hydrochloric acid or sodium hydroxide. Please only describe these additives on the Additives Grid. For more information on the additive review process, see the 'Additives Internet Page'. The required Additive Review Worksheets and SDSs are submited with the application attachments.

................ 35 WPDES Permit No. WI-0012345-01-0 PFAS Monitoring for Sewage Sludge (Biosolids) Generators 4 1 Requirements of 2025 Act 201 On April 6, 2026, 2025 Act 201 was enacted creating s. 283.82(4), Wis. Stats., which directed the department to issue a Wisconsin Pollution Discharge Elimination System (WPDES) general permit (GP) requiring perfluoroalkyl and polyfluoroalkyl substances (PFAS) monitoring conditions for sewage sludge. This GP applies to all sewage sludge generators with valid WPDES individual permits that do not have limitations or conditions addressing PFAS. In addition, s. 283.82(4)(b), Wis. Stats. requires the department to modify a WPDES individual permit (IP) assigned to a sewage sludge generator if sample results conducted under the GP exceed a 20 µg/kg concentration for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) combined. If the average of at least two sample results exceeds 20 µg/kg concentration for PFOA+PFOS combined, the department shall include limitations and conditions for PFAS in the reissued WPDES IP. The department created WPDES GP (WI-0012345-01-0) to cover sewage sludge generators (generators) which do not have PFAS conditions in the WPDES IP assigned to the generator. A sewage sludge generator is no longer eligible for coverage under this GP upon modification or reissuance of the generator’s WPDES IP assigned to include PFAS monitoring and conditions. WPDES Permit No. WI-0012345-01-0 PFAS Monitoring for Sewage Sludge (Biosolids) Generators 5 2 Applicability Criteria 2.1 Definitions and Responsibility Section NR 204.03(55), Wis. Adm. Code defines “sewage sludge” or “sludge” or “biosolids” as “the solid, semi-solid or liquid residue generated during the treatment of domestic sewage in a treatment works. Sewage sludge includes scum or solids removed in primary; secondary or advanced wastewater treatment processes and material derived from sewage sludge. Sewage sludge does not include ash generated during the firing of a sewage sludge incinerator or grit and screenings generated during preliminary treatment of domestic sewage in a treatment works.” Section NR 204.03(24), Wis. Adm. Code defines “generator” as “either the person who generates or prepares sludge during the treatment of domestic sewage in a treatment works or the person who derives a material from sludge or the person who changes the sludge characteristics either through treatment, mixing or any other process.” Section NR 204.09(41), Wis. Adm. Code defines “person” as “an individual, owner, operator, association, partnership, corporation, municipality, interstate agency, state agency or federal agency.” Section NR 204.03(19), Wis. Adm. Code defines “exceptional quality sludge” (EQ) as “sludge that meets the class A requirements for pathogens, as specified in s. NR 204.07(6)(a), Wis. Adm. Code, the high-quality pollutant concentrations, as specified in s. NR 204.07(5)(c), Wis. Adm. Code, and one of the pre-land application processes to reduce vector attraction, as specified in s. NR 204.07(7)(a) to (i), Wis. Adm. Code.” Section NR 204.02(2), Wis. Adm. Code explains sewage sludge generators responsibility for land application and disposal of sewage sludge, specifically: “RESPONSIBILITY: A facility that generates sludge is ultimately responsible for the handling, transporting, storage and land application or disposal of the sludge and grit and screenings. A generator is responsible for compliance with its WPDES permit and all applicable provisions of this chapter. In the event a generator sends its sludge to another person for final land application or disposal and that person alters the characteristics of the sludge by mixing it with other wastes or substances or by treating it in some other manner, then the person who receives the sludge shall also be considered a generator and shall assume primary responsibility for compliance with this chapter. If a generator gives the sludge to another person to land apply, but that person does not alter the characteristics of the sludge, then that person is also responsible for complying with applicable provisions in this chapter, such as the land management practices specified in s. NR 204.07, Wis. Adm. Code.” WPDES Permit No. WI-0012345-01-0 PFAS Monitoring for Sewage Sludge (Biosolids) Generators 6 Section NR 204.05(2)(a), Wis. Adm. Code, specifies WPDES permit requirements when sewage sludge is sent to another facility for treatment or storage, specifically: “If a treatment works sends its sludge to another treatment or storage facility for final treatment prior to land application, and at that facility, the sludge is mixed with other materials such as, but not limited to another municipal sludge, industrial sludge, animal manure or septage, or if the characteristics of the sludge are altered in any other manner, the owner of the receiving facility shall apply for a separate WPDES permit and shall assume primary responsibility for compliance with this chapter.” 2.2 Sewage Sludge Generators Covered This WPDES GP is applicable to any generator of sewage sludge (or “sludge” or “biosolids”) that do not currently have PFAS monitoring conditions in their WPDES IP. This GP applies to the following sewage sludge generators: 1.

Generators shall refer to the sewage sludge Outfalls designated under the WPDES IP. PFAS monitoring data shall be recorded on Characteristic Reports (Form 3400-49) under the Switchboard account of the WPDES IP sewage sludge generator. 3.1 Sewage Sludge Outfalls: General Most sewage sludge WPDES IPs have one or two sewage sludge sample point Outfalls to discharge sludge. Some sewage sludge WPDES IPs have additional Outfalls to accommodate EQ sewage sludge treatment processes along with pre- and post- processes necessary for the EQ sewage sludge treatment process. Typical sewage sludge discharge is from one primary sample point or Outfall. In most cases, the annual PFAS monitoring will be performed at a single Outfall. However, annual PFAS monitoring is required from all sewage sludge Outfalls when sewage sludge is discharged from those Outfalls during the calendar year. Sections 3.2 and 3.3 outline the procedures or situations where PFAS monitoring conditions would apply to sewage sludge Outfalls. 3.2 WPDES IPs with Single Sewage Sludge Outfalls Generators with a single sewage sludge Outfall identified in the WPDES IP shall monitor that sewage sludge Outfall pursuant to Sections 4, 5, and 6 of this WPDES GP. Annual PFAS monitoring is required from a sewage sludge sample point Outfall when sewage sludge is discharged from those Outfalls during the calendar year. 3.3 WPDES IPs with Multiple Sewage Sludge Outfalls Generators may discharge sewage sludge via multiple Outfalls identified in the WPDES IP assigned to the generator. In many cases, all required PFAS monitoring will be performed at a single Outfall only when sewage sludge is discharged from that Outfall. When sewage sludge is discharged from multiple Outfalls in a calendar year, PFAS monitoring is required from each of the Outfalls that discharge occurred. Many WDPES IP have Outfalls where discharges do not routinely occur (example: a lagoon facility may discharge sewage sludge once per 20 years). These infrequently used Outfalls provide flexibility in the WPDES IP for using dormant, inactive or emergency Outfalls. The generator must contact the department to report PFAS monitoring results if there is a discharge from a dormant, inactive, or emergency Outfall. WPDES Permit No. WI-0012345-01-0 PFAS Monitoring for Sewage Sludge (Biosolids) Generators 11 3.4 WPDES IPs without a Sewage Sludge Outfall In some unique situations, a WPDES IP may not include a sewage sludge discharge Outfall. These unique situations may include, but are not limited to, generators that infrequently discharge (example: once per 20 years) or generators that discharge sludge to another facility for treatment and that treatment facility has a WPDES IP. Generators shall notify the assigned department compliance staff within 90 days if the generator intends to discharge sewage sludge from a location that has not been covered as a sample point (Outfall) under the assigned WPDES IP. The department may provide coverage under this GP or require the modification of the WDPES IP assigned to the generator to include PFAS monitoring conditions. WPDES Permit No. WI-0012345-01-0 PFAS Monitoring for Sewage Sludge (Biosolids) Generators 12 4 PFAS Monitoring Requirements for Sewage Sludge Generators The following requirements shall apply to all EQ and non-EQ sewage sludge generators covered under this GP except those that apply under Sections 5 and 6. 4.1 Sampling Point(s) Sampling Point Designation Monitoring shall occur at all sewage sludge sample point Outfalls prior to discharge of sewage sludge via land application, distribution to other WPDES permitted facilities, or disposal at licensed incinerator or licensed landfill. The generator shall refer to the WPDES IP for the appropriate Outfall identification number(s) needed to complete the electronic Characteristic Report (Form 3400-49). Note: This section does not apply to WPDES permitted contract haulers, facilities with lagoon treatment processes, and facilities with reedbed treatment processes. 4.1.1 Land Application of Sludge Containing PFAS The sewage sludge generator shall monitor PFAS concentrations in the sewage sludge prior to the sewage sludge being discharged from all Outfalls. The department recommends the land application of sewage sludge be completed in a manner consistent with the most recent version of the “Interim Strategy for Land Application of Biosolids and Industrial Sludges containing PFAS” (https://dnr.wisconsin.gov/sites/default/files/topic/PFAS/PFAS_BiosolidsInterimStrategy.pdf). Note: The department intends to periodically review and update this interim strategy. 4.1.2 Monitoring Requirements The generator shall comply with the following monitoring requirements. Parameter Units Sample Frequency Sample Type Notes Solids, Total Percent Annual Composite PFOA + PFOS µg /kg Annual Calculated Report the sum of PFOA and PFOS. Results greater than 20 μg/kg.

Note: As part of this GP the department has created a dedicated Characteristic Report (Form 3400-49) to record all PFAS sewage sludge monitoring results. This form identifies the due date of January 31 following the year of analysis. The requirement to complete and certify the form within 14 days of receipt of PFAS laboratory results supersedes the date listed on the form. The sewage sludge generator may request additional Characteristic Reports to record PFAS monitoring results. WPDES Permit No. WI-0012345-01-0 PFAS Monitoring for Sewage Sludge (Biosolids) Generators 25 Representative sludge samples shall be collected at each Outfall. The liquid sludge storage/digesters should be thoroughly mixed prior to sampling. Cake sludge samples should consist of seven equal size discrete samples and be collected from different areas and depths, then composited into one sample for laboratory analysis. The department may require representative sampling procedures to be detailed in a sludge management plan pursuant to s. NR 204.11, Wis. Adm. Code. Note: If additional equipment is used for collecting sewage sludge samples (i.e., shovels, compositing buckets, bottles, etc.), then a one-time equipment blank is recommended to be collected with the first sample. An equipment blank sample is collected by passing laboratory verified PFAS-free water over or through field sampling equipment before the collection of a representative sludge sample. The equipment blank result shall be reported on the Characteristic Report (Form 3400-49) in the comment section when reporting PFAS concentrations in the sludge. The generator shall use the following convention when reporting sludge monitoring results: Pollutant concentrations less than the limit of detection shall be reported as < (less than) the value of the limit of detection. For example, if a substance is not detected at a detection limit of 1.0 mg/kg, report the pollutant concentration as < 1.0 mg/kg. 7.3 Sludge Testing Procedures The laboratory performing the analysis on any samples shall be certified for the applicable PFAS compounds in the solids matrix by the Wisconsin Laboratory Certification Program established under s. 299.11, Wis. Stats., and in accordance with s. NR 149.41, Wis. Adm. Code.

Note: Section 292.11(2)(a), Wis. Stats., requires any person who possesses or controls a hazardous substance or who causes the discharge of a hazardous substance to notify the department immediately of any discharge not authorized by the permit. The discharge of a hazardous substance that is not authorized by this permit or that violates this permit may be a hazardous substance spill. To report a hazardous substance spill, call DNR's 24-hour HOTLINE at 1-800-943-0003. 8.3.6 Planned Changes In accordance with ss. 283.31(4)(b) and 283.59(1), Wis. Stats., the permittee shall report to the department any facility expansion, production increase or process modifications which will result in new, different, or increased discharges of pollutants. The report shall either be a new general permit notice of intent or, if the new discharge will not violate the effluent limitations of the general permit, a written notice of the new, different or increased discharge. The notice shall contain a description of the new activities, an estimate of the new, different, or increased discharge of pollutants, and a description of the effect of the new or increased discharge on existing waste treatment facilities. Following receipt of this report, the department may modify the general permit coverage letter to specify any discharges of pollutants not previously covered by the general permit. 8.3.7 Duty to Halt or Reduce Activity Upon failure or impairment of treatment facility operation, the permittee shall, to the extent necessary to maintain compliance with its permit, curtail production or wastewater discharges or both until the treatment facility operations are restored or an alternative method of treatment is provided. 8.3.8 Enforcement Any violation of this permit is enforceable under ss. 283.89 and 283.91, Wis. Stats. 8.3.9 Permit as Enforcement Shield Compliance with a permit during its term constitutes compliance for purposes of enforcement with 33 USC 1311, 1312, 1316, 1317, 1328, and 1345 (a) and (b), except for any toxic effluent WPDES Permit No. WI-0012345-01-0 PFAS Monitoring for Sewage Sludge (Biosolids) Generators 33 standard or prohibition, and standards for sewage sludge use or disposal. If a new or revised toxic effluent standard or toxic prohibition becomes effective during the term of the permit, the permittee may be subject to enforcement action if the discharge exceeds the new or revised effluent standard for the toxic pollutant even though the discharge is in compliance with the existing permit. The permittee may also be subject to enforcement action standards for sewage sludge use or disposal. However, a permit may be modified, revoked and reissued, or terminated during its term for cause as set forth in ch. 283, Wis. Stats., and ch. NR 203, Wis. Adm.
