Utilities Superintendent Benson called the meeting to order at 8:00 a.m. Present: Chairman Speedling, Commissioners Hutter and Whitcomb Absent: Commissioners Hudak and Jensen, Councilmember Polehna Staff: Utilities Superintendent Benson, Public Works Director Sanders APPROVAL OF MINUTES Possible approval of minutes of November 4, 2021 meeting Motion by Chairman Speedling, seconded by Commissioner Whitcomb, to approve the November 4, 2021 meeting minutes. All in favor. OPEN FORUM There were no public comments. NEW BUSINESS Discussion on water service from Roger Ryan Roger Ryan, 1016 N 3rd St, presented two quotes from $15,000 to $17,800 for insulation of his water service. He explained where the freezing is occurring due to the design of the system. When the waterline was constructed to his property they went out the north side of the line, up and over a telephone conduit, and then down to his property. Commissioner Whitcomb asked if repair work between the main and the house is usually at property owner expense. Superintendent Benson answered yes. In other areas where water typically freezes in pipes, residents are asked to leave the water running because the expense of running the water is less than the cost of repair of the line. This situation is unique due to the design of the waterline. It is the only property that has the service going up and around. Public Works Director Sanders confirmed that water service repairs on street projects are typically assessed 100% to the property owner. Commissioner Whitcomb commented the City Council may deny the request regardless of the Utilities Commission's recommendation. He could not recommend approval because it sets precedent. Commissioner Hutter agreed. Mr. Sanders stated Mr. Ryan could bring the request to a City Council meeting during the open forum. Discussion on funding for Utility Improvements on Street Projects Public Works Director Sanders stated that staff is considering the replacement of the watermain on Brick Street between Olive and Myrtle Streets as part of the 2022 Street Improvement Project. The main was constructed in 1961 and has had eight breaks since 1980. Brick Street will be reconstructed and now would be a good time to replace the watermain. The estimate to replace the main is $40,000. Staff is requesting to fund the replacement with water revenue funds. Utilities Commission Meeting March 10, 2022 Motion by Commissioner Whitcomb, seconded by Chairman Speedling, to recommend approval of the request to replace the watermain on Brick Street and to use water revenue funds. All in favor. UNFINISHED BUSINESS White Bear Lake Court Case Update Mr. Sanders reviewed a report on the White Bear Lake Court Case, provided by Randall Doneen and Jason Moeckel, Section Managers, DNR Ecological and Water Resources. He noted that the DNR is to set a collective annual withdrawal limit for White Bear Lake and adjust permits accordingly. State Statute deems first priority is domestic water supply, excluding commercial and industrial uses, such as schools, government agencies, and hospitals. Based on the City's 20,000 residents the withdrawal limit would be a little more than 500,000 gallons per year. Current usage is around 750,000 gallons, so the limit would have a significant impact. Legislation has been introduced that would allow Cities to continue to operate per their water supply plan that was submitted in 2016 until 2040. The bill has not gone to a hearing yet. DIRECTOR/SUPERINTENDENT UPDATE Monthly Updates Mr. Sanders provided the monthly gallons pumped, 43,203 in January and 39,409 in February. Water Appropriation use and efficiency profile Mr. Sanders provided a water use report from the Department of Natural Resources. Met Council Water Efficiency Grant Program Mr. Sanders explained that the City is applying for a grant of up to $50,000 under an 80/20% match. The grant money may be used to offer rebates to residents purchasing water saving devices. COMMISSIONER ITEMS Mr. Sanders noted if Thursday at 8 a.m. is a difficult time for Commissioners, the meeting time can be changed. This will be discussed at the next meeting. ADJOURNMENT Motion by Chairman Speedling, seconded by Commissioner Hutter, to adjourn. All in favor. The meeting was adjourned at 8:37 a.m. ATTEST: Robert Benson, Utilities Supervisor Steve Speedling, Chair Page 2 of 2 i 1 INki ater THE OIRTHELACE OF MINNESOTA UTILITIES COMMISSION MEETING April 14, 2022 8:00 A.M. Utilities Superintendent Benson called the meeting to order at 8:00 a.m. Present: Vice Chairman Hudak, Commissioners Jensen and Whitcomb, Councilmember Polehna Absent: Chairman Speedling, Commissioner Hutter Staff: Utilities Superintendent Benson, Public Works Director Sanders APPROVAL OF MINUTES Possible approval of minutes of March 10. 2022 meeting Vice Chairman Hudak tabled the approval of the minutes to the next meeting. OPEN FORUM There were no public comments. NEW BUSINESS 1315 Fifth Avenue South Water Service Public Works Director Sanders reported that in December, the property owner at 1312 Fourth Avenue South notified the Utility Department of water in their basement. Upon investigation, it was determined there was a leak in the water service, not for 1312 Fourth Avenue South, but for the property located at 1315 Fifth Avenue South. This property is served from a galvanized pipe coming from the main on Fourth Avenue that was installed over 70 years ago. (There is no watermain located on Fifth Avenue South). To make matters worse, the service is thought to be located under the garage and under an in -ground pool at the property at 1312 Fourth Avenue South. The property owner is reluctant to repair the existing service because of the potential high cost to repair the pool or garage. Other options include connecting to the watermain on Fourth Avenue South or Orleans Street at a cost of $35,000+, the high cost due in part to wintertime construction, length of service and potential to encounter rock during construction. The property owner has also considered drilling a private well, and was quoted about half the cost of connecting to the watermain, however all costs may not be included. City code states that properties shall connect to water if it is available. The question is, is it considered "available" where the closest connection to the house is 200 feet away? Vice Chair Hudak noted that if other nearby homes have galvanized services, this will likely be a recurring problem. It would be preferable to avoid having each of these properties in the future drilling wells. Additionally, well maintenance every 5-10 years can be costly for the property owner. Commissioner Whitcomb remarked in his opinion as a citizen, the best long term solution is to do a directional bore to connect to existing watermain. Motion by Commissioner Whitcomb, seconded by Commissioner Jensen, to uphold City policy of requiring the property owner at 1315 Fifth Avenue South to connect to City water via a directional bore, and not allow for a private well to serve the property. All in favor. Public Works Director Sanders said he will inform the homeowner. Nightingale Boulevard Water Bill Utilities Commission Meeting April 14, 2022 Mr. Sanders provided a letter from a resident on Nightingale Boulevard who received a utility bill for $2,300 due to a water softener that kept recycling and draining into the sewer drain. According to City policy, a property owner is responsible for charges for whatever goes through their meter (water) and whatever goes down their drain (sewer). In addition, the sewer bill for the remainder of the year is based on 1st quarter usage. The property owner is asking the charge to be waived or reduced. Commissioner Whitcomb suggested that the Finance Department adjust the sewer bill for the remaining quarters, and pay the water charge as billed on a payment plan. Commissioner Jensen said if the bill is adjusted, it must be well documented for future such requests. Vice Chair Hudak reminded residents if they are going to be on vacation, they should shut the water off and have someone check on their house, or bypass their water softener. Motion by Commissioner Hudak, seconded by Commissioner Whitcomb, to recommend that the City charge the property owner per the existing water bill and work with the Finance Department toward a payment plan (less than 12 months), and adjust the sewer bill for the rest of 2022. All in favor. UNFINISHED BUSINESS There was no unfinished business. DIRECTOR/SUPERINTENDENT UPDATE Monthly Water Use Mr. Sanders provided the monthly gallons pumped, 39, 409 in February and 41, 176 in March. Update on Utility Dept. Capital Outlay Items Mr. Sanders updated the Commission on utility construction projects for 2022. He pointed out the cost for the Mid Oaks lift station rehab includes paying property owners for easements because when the lift station was installed in the 1970s, there were no utility easements for the lines that go through private properties. Water Efficiency Grant Program Update Mr. Sanders explained that he applied for a Met Council water efficiency grant to help reimburse residents who replace high -flow toilets, washing machines, and get smart controllers. The grant would be 80/20, $40,000 Met Council and $10,000 City. It would be a two year program starting July 1, 2022. COMMISSIONER ITEMS Commissioner Jensen noted her term is up in June and she is considering stepping down and allowing someone else to serve due to health issues requiring treatments on Thursdays. Mr. Sanders and the Commissioners who were present said they would be happy to change meeting dates so Commissioner Jensen could stay on. Mr. Sanders will poll the other Commissioners by email. ADJOURNMENT Motion by Whitcomb, seconded by Commissioner Hudak, to adjourn. All in favor.

Council directed staff to work with the property owner on an agreed amount for the utility bill. After the meeting, our City Attorney presented information on utility adjustments from the South Saint Paul, City Code. Their code gives the consideration of utility bill adjustments to City staff, rather than having to go to the commission or the council. and would consider adjustments under certain conditions, such as billing errors, water line freeze and water break or malfunction. Staff has read though the code and is proposing similar language to code for utility bill adjustments. (The utility bill adjustment section of the code is attached) RECOMMENDATION Staff recommends that the commission review the code and direct staff to bring an updated version for final approval. ACTION REQUIRED If the commission agrees with the recommendation, they should pass a motion directing staff to proceed with preparing an addition to the City Code for utility bill adjustments. South St. Paul, MN Code of Ordinances about:blank Sec. 62-56. - Adjustments to utility bills. \Apfr 1.. (a) Policy and purpose. It is the policy of the city of South St. Paul to make adjustments to consumer water bills where an adjustment is necessary to correct mistakes, equipment failures, or fairly apply the rates and rules. The purpose of this policy is to improve consumer service by enabling city staff to quickly and accurately respond to consumer requests for adjustments to water bills. (b) Requests for adjustments. When a consumer disputes a water bill, the consumer may request an adjustment for one of the reasons set forth in section 62-56(d). All requests for adjustments must be made in writing within 14 days of the date the water bill was sent, addressed to the finance director. Written requests shall state the name of the account holder, service address, contact information and the reason for the requested adjustment. The consumer shall further provide all information requested by the panel deemed necessary to make a determination on the request. (c) The panel. A panel made up of the city engineer, public works director, and finance director, their designees, or members appointed by the city administrator, shall determine the amount, if any, of the adjustment to be made. (d) Adjustments allowed. (1) The panel is authorized to make adjustments to water bills, without prior city council action, for the following situations: a. Billing error. Where an error has occurred that results in an inaccurate water bill being sent to a consumer, staff shall correct the error as soon as discovered, whether by the consumer or by staff. These adjustments include data recording and entry errors as well as meter failures if tested and found to be inaccurate. b. Water line freeze. Adjustments to charges when a consumer experiences extraordinary water consumption during a billing period following a water line freeze and the city advised the consumer to leave a drip running during the period of time covered by the water bill. c. Water break or malfunction. If the panel is shown evidence that the consumer made a good faith effort to address a break or malfunction in a timely manner, then the rate may be adjusted to a lower tier for the billing cycle in question and the winter quarter average may be re-established to a rate based on usage history. (2) After an adjustment is made by the panel, the bill is due and payable within 14 days of the panel's decision. (e) Adjustments not allowed. The panel will not consider adjustments when a consumer experiences extraordinary water consumption due to a break or malfunction and the 1 of 2 5/6/2022, 3:57 PM South St. Paul, MN Code of Ordinances about:blank consumer has not made a good faith effort to address the break or malfunction in a timely manner or when the appeal is untimely.

No. 1283, § 1, 4-7-2014; Ord. No. 1319, § 1, 8-7-2017) 2 of 2 5/6/2022, 3:57 PM South St. Paul, MN Code of Ordinances about:blank Sec. 62-166. - Billing and payment. (a) Timing; penalty. Water and sewer services are billed on the same statement, with sewer and water charges listed separately. Bills are sent quarterly except that high volume user consumers are billed monthly. Accounts must be paid 30 days following billing, at which date the accounts become delinquent. A penalty will be added to the balance of delinquent accounts as established by chapter 26 of this Code. (b) Deferral. Upon the verified application of a user prior to certification of unpaid charges to the county auditor for collection with taxes, the council may defer the collection and payment of sewage or water charges or a portion of either to a future date or dates and upon such terms and conditions as the council may determine, in those cases in which the council finds that payment thereof when due cannot be made because of a present temporary adverse economic situation of the user, and collection and payment when due would result in undue economic hardship to the user. Adjustment. In the event a bill is abnormally high because of a verifiable faulty plumbing system which has been or will in the near future be repaired, the customer shall pay the current bill, but an equitable adjustment shall be made by setting the sewer maximums back to the prior year, or to the average of the last two years, or to an average based on family size, whichever is most appropriate under all of the circumstances. The finance director or designee is delegated authority to make the adjustment in accordance with the foregoing criteria. (Ord.

With the change to quarterly billing for all properties, the rate change for commercial properties does not coincide with the City's quarterly billing cycle. Previously, commercial properties were billed monthly. The Finance Department is proposing to adjust the commercial billing rate to match that of the billing cycle which would add April and remove October from the seasonal rate. RECOMMENDATION Staff recommends that the Commission discuss and review the proposed the seasonal rate billing change. If approved, staff will bring the request to the City Council. ACTION REQUIRED If the Commission agrees with recommendation, they should pass a motion recommending changing the seasonal commercial utility rate from May -October to April - September.

This is an area of active research, and 1 One microgram per liter is the same as one part per billion (ppb). 2 STATEWIDE PFAS MONITORING RESULTS scientists at MDH and EPA have not yet determined whether these contaminants in drinking water at this level poses a health concern. As we learn more about them over time, we will let you know. Perfluorobutyrate, or perfluorobutanoic acid, (PFBA) is one of a group of related chemicals known as perfluorinated alkylated substances (PFAS). This group of chemicals is commonly used in non-stick and stain -resistant consumer products, food packaging, fire -fighting foam, and industrial processes. PFBA can be a breakdown product of other PFAS. PFBA moves easily through the environment and is widely detected in groundwater, surface water and in nature. PFBA is the most commonly detected PFAS in Minnesota waters. PFBA is commonly found in drinking water at low levels.

Exceedance of the HRI indicates a health concern for the combined PFAS exposure. The HRIs for these samples range from 0.03-.58. A person drinking water at or below an HRI of 1 would have little or no risk for health effects. Next Steps Because the detected results are above an HRI of 0.5, Minnesota Department of Health (MDH) will conduct follow-up sampling for three quarters to ensure that PFAS levels remain consistently below an HRI of 1. Your district engineer will begin this sampling next quarter. 3 STATEWIDE PFAS MONITORING RESULTS If the average HRI is greater than 1 after four quarters of sampling, MDH will send a Health Risk Advisory letter recommending that you provide public notice to your customers about the PFAS levels in your water supply and that you take action to reduce exposure. As a standard process, MDH notifies area legislators and the governor's office when a Health Advisory Letter is issued. MDH can provide resources to help you communicate with your customers about what these results mean. About the project MDH has been studying the potential health impacts of PFAS in groundwater in Minnesota since 2002. This project is part of a larger effort at MDH to sample all community water systems (CWSs) for PFAS. MDH aims to cover 90% of CWS customers under its PFAS monitoring program by 2025. The project has been made possible through funding from the Clean Water Fund and U.S. Environmental Protection Agency. Sampling results from all systems that participated in the study will be included in an interactive mapping application on the MDH website. MDH will also be providing these results to the Minnesota Pollution Control Agency to make them aware of the contamination.
