Chairperson Johnson called the meeting to order with Commissioners Demuth and Miller. Staff present included the following: City Administrator Logan Martin, Public Works Director Nick Egger, Mayor Weisensel, Recording Secretary Amy Simonson ADDITIONS OR CORRECTIONS TO AGENDA None. AUDIENCE INPUT None. APPROVAL OF MINUTES 4.a. March 25, 2024, Utility Commission Meeting Minutes Motion by Johnson Second by Demuth Motion to approve the March 25, 2024, Utility Commission meeting minutes as presented. Ayes: 2. Commissioner Miller abstained. Nays: None. Motion Carried. PUBLIC HEARINGS None. OLD BUSINESS 6.a. Manganese Discussion & Update Director Egger informed the Commissioners about discussions with the City Council during the June work session regarding water treatment plant options and manganese levels in drinking water. A consultant presented various water treatment options to the Council. It was noted that due to the layout of the water network, more than one treatment plant would be required to treat all city water. The city currently meets the Minnesota Department of Health (MDH) guidelines, and staff is monitoring manganese levels. Current manganese levels are within MDH standards, and manganese is not a federally regulated issue. The Council suggested that staff test water for manganese at selected homes throughout the city over the course of one year to determine levels on a regular basis and to obtain a range of data points. Testing from the customer end point, as opposed to the wellhead, will provide information on the level of system blending from the wells to the tower. Logistics for selecting properties and testing frequency are still being worked out. Page 2 of 53 Commissioner Miller inquired if there are any other cities with a population of 40,000 or more without a water treatment plant. Staff clarified that there is no requirement to have a water treatment plant; it is only necessary to remove certain regulated elements if required. Commissioner Demuth suggested that the city provide carbon ion exchange filters to all households with infants. Director Egger noted that the Council discussed this option, but no decision was made. The annual Consumer Confidence Report was posted on the city website in April and was featured in the spring city newsletter. A link was added to the Manganese outreach information. NEW BUSINESS None. EXECUTIVE DIRECTOR’S REPORT 8.a. Well Pumping Report Commissioners inquired about the decision-making process for operating the wells. Director Egger explained that the SCADA system uses a sequencing matrix to activate wells based on demand, the pumping capacity of each well, and the distribution requirements. Staff will invite the Public Works Utilities Supervisor to the next meeting to discuss the specifics in greater detail. 8.b. Water Efficiency Grant Update Staff will work to develop a city HOA irrigation audit program as the Vermillion River Watershed Joint Powers Organization discontinued their program. 8.c. Major Projects Update Parks staff reported that the seed mix used in new city parks consists of 80% fescue and 20% rye and bluegrass and contains four types of fescues. Staff provided an update on the city's collaboration with the developer of the Amber Fields project on the design of the private park. The park will include a central stormwater pond with primarily native plantings, and irrigation will be used only to establish the vegetation. The city continues its efforts to install Variable Frequency Drives (VFD) in its wells. A VFD was installed at Well 8 last fall, leaving Wells 9, 12, and 15 as the only wells without VFDs. Installation and retrofitting for these wells are planned over the next few years. The city is addressing the Federal Mandate to inventory lead service lines. Notices were mailed to property owners of homes built before January 1, 1985, requesting they complete an online survey. Additional notices were posted on the city website, social media platforms, and in the newsletter. Commissioners inquired about the city's service line inventory. Staff reported that information from as-built records confirmed there are no lead water mains in the city. Page 3 of 53 8.d. Action Item / Issues list None. 8.e. Set Next Meeting Agenda – September 23, 2024 None. ADJOURNMENT There being no further business to come before the Utility Commission at the regular meeting and upon a motion by Demuth and a second by Miller, the meeting was adjourned at 7:36 p.m. Respectfully submitted, Amy Simonson Recording Secretary Page 4 of 53 EXECUTIVE SUMMARY Utility Commission Regular Meeting: September 23, 2024 AGENDA ITEM: Manganese Monitoring Update AGENDA SECTION: OLD BUSINESS PREPARED BY: Nick Egger, Public Works Director AGENDA NO. 6.a. ATTACHMENTS: Manganese Sample Locations Map, Manganese Sample Results Q3 2024, Manganese Sample Results Chart MVTL vs. City Measurements Q3 2024, MVTL Sample Results Report - August 2024 APPROVED BY: NAE RECOMMENDED ACTION: No Action - Informational Only BACKGROUND As discussed at the June Utility Commission meeting, the City Council supported staff recommendations to collect water samples from homes, businesses, and public locations around the City at the consumer tap end to have those samples analyzed for manganese concentration for the purposes of getting a true sense of concentration on the consumer end. Previously, manganese concentrations have only been determined for the source water coming directly out of each City well, which is not the point at which a consumer receives water. With a wider set of results to show the reality condition of the water arriving at the point of consumption, the City will gain insight as to how source water is blending and commingling within the system prior to reaching the consumer. This work was directed to occur over at least one calendar year, with samples being collected quarterly to establish trend lines. In early August, the first set of samples was collected from 36 locations around the City for a good representation of the geographic area and primary population center served by the City's water distribution system. Samples were analyzed at a local level by City staff with recently acquired testing equipment, while a companion sample was also sent to Minnesota Valley Testing Lab for an independent analysis and report. A map of the sample locations, along with a tabulation of the corresponding property addresses, type, sample location at the property (i.e. sink, exterior spigot, etc.), and documentation of the presence of a water softener or other form of on-premesis treatment on the plumbing system, have all been attached for reference. Each sample result for the August sampling run has been listed alongside the address. A bar graph of concentrations from the samples run by the City, and run by MVTL has also been included for illustration purposes. The results of the first run of sampling show that at most locations consumer-end manganese concentrations of delivered water are below the concentrations at the well heads,with some exceptions. Additionally, concentrations reported from the MVTL-analyzed companion samples are Page 5 of 53 consistently slightly lower than what the City-owned equipment determined. A copy of the MVTL issued reports for each sample have been attached for the Commission's reference. Please note, although results are accurately attributed to the correct location in the map, tabulation, and bar chart documents, the MVTL report sheet document sequence does not follow that same order. This information is only a first round of results. The City will continue to perform the sampling rounds each quarter through at least the summer of 2025. Ultimately, at the conclusion of the study trends will become apparent, and staff will have further discussion with the Commission and the City Council on recommended next steps, which could include the pursuit of a blending facility/manifold, treatment plant(s), some other form of mitigation, or no further pursuit at all. From a communications standpoint, the City did highlight and enhance the annual water quality report to directly identify manganese in the unregulated contaminants section of the document, and to point out where additional information can be reached. Additionally, this fall we will be sending out another round of courtesy letters to clinics and daycares in the area as a refresher and to ask for their assistance with communicating to their clients and patients.

Report Date: Page 51 of 53 EXECUTIVE SUMMARY Utility Commission Regular Meeting: September 23, 2024 AGENDA ITEM: Kick-off to Review of 2025 Utility Rate Review AGENDA SECTION: NEW BUSINESS PREPARED BY: Nick Egger, Public Works Director Teah Malecha, Administrative Services Director AGENDA NO. 7.a. ATTACHMENTS: APPROVED BY: NAE RECOMMENDED ACTION: Review and Feedback BACKGROUND The Utility Commission reviews proposed utility billing rate adjustments each year. The City's rate model brings together a multitude of known and estimated operational and capital improvement expenses to distill into proposed adjusted rates. Staff will walk through the preliminary operations budget and the Capital Improvement plans for the Water, Sanitary Sewer (Wastewater), Stormwater, and Street Lighting funds with the Commission to illustrate what program costs are at hand for the near term in 2025 as well as looking forward to future years. Additionally, staff will walk the commission through the utility rate model workbook to show how these operational and capital improvements, along with future anticipated expenses, tie into rate projections. Lastly, staff will provide a summary of 2024 rates for neighboring communities for a frame of reference. The Commission's feedback from this meeting will be taken into account as staff continues analysis work into October and formulates recommended adjustments for the Commission's consideration at the next meeting.
