This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit #NC0059200. RPB Systems and Trillium staff were present and assisted in the inspection. The following items were noted during inspection: Operational staff indicate they still have limited ability to alter settings beyond what was originally programmed for the WWTP within the SCADA system. Bar Screen: A 2mm fine screen is installed. Brushes were replaced for the first time in 2023. No reported issues or major pass-through debris noted. EQ Basin: A pressure transducer is used to monitor the level in the EQ basin, which is connected to SCADA. Any alarms triggered will call Trillium staff who will contact RPB systems. ORC states he can pull the transducer up and down to determine if it is reading the liquid level accurately. Oxic and Anoxic Basins: The ORC checked the DO and MLSS with field meters at the time of the inspection. DO read 0.72 mg/L and the MLSS was showing approximately 10,000 mg/L. The ORC indicated the MBR literature states the membranes can handle a higher solid content but based on his experience with the facility, there are issues with running the solids at the manufacturer suggested levels. MBRs: Membranes were replaced in November of 2021 and there have been no tears noted to the membranes since they were installed. Staff indicated if there is too much suction detected on the membranes, the pumps will shut down to prevent damage. When the clean alarm sounds, staff will perform a filter wash. The ORC performs a chlorine wash once a quarter and washes with just water monthly. The original clean in place (CIP) system is still inoperable. DWR still recommends staff attempt to fix or alter this system so the ORC does not need to climb to the top of the building to feed cleaning chemicals. Blower Motors: It should be noted the EQ basin and membranes tanks share blower motors, which limits how much the ORC can adjust the power to the motors depending on the season. The old motors are retained onsite as spares in case there are any issues with the motors in operation. Solids: ORC reports Mike’s septic pumps the facility monthly in the peak season. Solids were most recently removed on June 9, 2024. Flow meter: Facility utilizes a mag meter and was previously verifying effluent mag meter flow readings by measuring volume/time and comparing to the mag meter reading. At the time of the inspection, the ORC reported the meter was not being calibrated/verified to be within 10% of true value annually. Please note, per Part II.D.3 of the NPDES Standard Conditions this must be done, at a minimum, annually. Due to the nature and placement of the mag meter, staff can verify the reading is accurate by checking discharge volume/time and, if possible, checking any diagnostics for the meter within the SCADA system set by the manufacturer. Please notify the ARO, once the calibration verification has occurred and the associated percentage error. Should the percentage error exceed 10%, the permittee will need to replace or send off the mag meter for calibration. Trillium should also reach out to the mag meter manufacturer (IFM) to see if they have any recommendations for in-situ calibration verifications. Inline turbidimeter: An inline turbidimeter is installed. The ORC stated he relies on turbidity samples taken as he is unsure of the accuracy of the inline turbidimeter. Please note, if/when the infiltration NC0059200 17 (Cont.)

Generator: Onsite generator tests underload daily at approximately 1330. Blossman gas refills the propane tank onsite and Trillium maintains a contract with a local company to service all the generators. The propane tank was reading 80% full at the time of the inspection. Outfall- Trillium staff maintain the path to the outfall near well #7. Recommend the outfall location be marked for future facility staff to easily locate. US/DS: ORC reports no issues accessing the sampling location 100’ upstream and of the outfall and at the mouth of the UT to Thorpe Lake. Noted Deficiencies: Flow Measurement: A calibration verification is not being conducted annually as required by permit.
