1139087 08/03/2024 Order Conditions The Discharger stated that low UV dosing occurred for two days in August 2024 due to high flow rate testing of the new MBR treatment system. Violation N Report Mountain House WWTP 453528 R5-2023-0033 Y
1139086 07/24/2024 Order Conditions The Discharger violated the UV system operating specification for UV dose contained in the WDRs. The Discharger stated the UV dosing was set below the lower order condition limitation throughout most of July 2024 due to a misunderstanding with the UV dose limitation associated with MBR treatment. The UV dose was increased to a level above the lower order condition limitation on 25 July 2024. Violation N Report Mountain House WWTP 453528 R5-2023-0033 Y

1131104 06/30/2024 Order Conditions The Discharger violated the UV system operating specification for UV dose contained in the WDRs/NOA. The Discharger stated that they lowered the target dose to 80 mJ/cm2 according to new MBR process guidelines rather than maintaining permit requirement of 100 mJ/cm2. The Discharger increased the target dose back to 105 mJ/cm2 when they realized the permit limit had not been amended. After returning to the higher target dose, the Discharger noted average dose was still dipping below the setpoint and identified several UVI sensors that were causing the dose to be calculated artificially low. The Discharger replaced the faulty sensors in July 2024 and UVI dose calculations are now above the 100 mJ/cm2 permit requirement. Violation N Report Mountain House WWTP 453528 R5-2023-0033 Y
