Sanitary Sewer Overflows (SSOs): No sanitary sewer overflows occurred during the month of May 2025 4|Page 5 Financial The Project continues to be well under budget for both the Maintenance and Chemical Rebateable accounts. Oxygen expenses have started to impact the Chemical Rebate Account and will continue to pressure our budget, however, we are under budget for now.

The new units replaced two older surface mount aerators that were at the end of their service life due to age and the lack of available parts. Once the new units were tested, Aeration Basin 1 was brought online to meet the demands of high flows and summer temperatures. So far, the jet aerators are producing 2.0ppm dissolved oxygen during daytime flows while using 58 amps of power each. By comparison, the older surface mount aerators installed in the corresponding positions on Aeration Basin 2 are using an average of 96 amps of power to produce equivalent amounts of dissolved oxygen. As a result, the new jet aerators are using 40% less power to aerate basin 1 than the older units in basin 2. Inframark staff will continue to monitor the new aerators and the basin. Of particular interest will be the jet aerators ability to keep the mixed liquor suspended inside the basin, without having biosolids accumulate in areas were the turbulence and flow velocity are lower. So far, there is no evidence of solids settling in the basin. 6|Page 7 Maintenance UV Disinfection One of the focal points during the month of May was restoring the capability of the UV disinfection system at the Westside WWTF. Over the last year, a number of the bulbs had failed, reducing the effectiveness of the UV system. Inframark was able to locate an alternate supplier for compatible bulbs, reducing the cost by over 30%. With the new bulbs installed, fecal coliform counts for the facility have dropped and we are much better able to deal with the high storm related flows that have pushed through the plant over the past few months. Laser Alignment During the start up of Aeration Basin 1, care was taken to align the motors and gearboxes of the surface aerators that moved to accommodate the jet aeration system. Proper alignment greatly increases the service life of equipment by reducing the strain on the output bearing of the electric motor and the input bearings of the gearbox. At the end of the alignment process, the motor and gearbox were within five thousandths of an inch (0.005) of true. By comparison, the motor when initially bolted to gearbox was over three hundred eighty thousandths (0.380) out of alignment which would have resulted in extreme wear and early failure of both the electric motor and gearbox. 7|Page 8 Pretreatment For the month of May, staff have collected several discrete composite samples from the effluent of Con Agra as part of our industrial surveillance program. In addition, Inframark met with Wolfspeed to facilitate removing them from the Categorical Discharge classification. Lastly, revenue is somewhat high this month due to the unusually high surcharges for Tyson Foods.

Currently, two drying houses per week are being processed through the belt dryer, achieving greater than 92% solids on a single pass. 9|Page 10 Noteworthy Activity During May 2025, Inframark hosted four (4) tours of the Westside WWTF. The groups included children from both middle school and high school and totaled over 200 students. 10 | P a g e 11 Woolsey Wet Prairie Inframark staff have conducted several surveys at Woolsey this month and applied herbicide to non native species found at the site. Below are the areas we've covered: Surveys conducted in Buffer zones and E1-5 Herbicide Applied: 2 gallons glyphosate (2%) applied in E3 2 gallon glyphosate (2%) applied in East Buffer Zone 2 gallons glyphosate (2%) applied in E2 1 gallon glyphosate (2%) applied in E1 Species targeted were Fescue, Yellow Rocket, and clover.
