The purpose of the evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit WQ0003044. Don and Karrie O'Mara were present during the inspection. This facility is a 50,000 gpd Integrated Surge Anoxic Mix SBR system with a high -rate infiltration system consisting of three surface LPP fields. The current facility was constructed and put into operation in July 2017 to replace the old plant. There has been no effluent violations since the summer of 2017. A review of GW-59s, since last inspection in 2019, show some TDS limit exceedances in MW-6. This permit expires in March 31, 2022. A renewal application will need to be submitted by October 1, 2021. The facility is compliant with Non -Discharge Permit WQ0003044. Please review the comment sections of the inspection report for more details.
