1148309 10/01/2025 LREP Once Only OneTime ( TECHRPT ) (Salinity Evaluation and Minimization Plan) report for 2021/10/01 (2518373) was due on 30-SEP-25 Violation B Report
1146420 07/21/2025 OEV Total Coliform 7-Day Median limit is 23.0 MPN/100 mL and reported value was 33.0 MPN/100 mL at EFF-001. Upon the result of the test, we immediately switched chlorine contact basins for our Effluent and cleaned the one that we were using to avoid further issues/violations. If we see any more higher numbers/results, then we may consider switching our chlorine contact basins on a more frequent basis, rather than once per month. Violation B eSMR
1124392 01/29/2024 OEV Total Coliform 7-Day Median limit is 23 MPN/100 mL and reported value was 33 MPN/100 mL at EFF-001. The EFF-001 will be closely monitored and any subsequent violations, should they occur, will be immediately reported to our regulator for any follow-up corrective actions. Violation U eSMR

*As of 5/20/2010, the Water Board's Enforcement Policy requires that all violations be classified as 1, 2 or 3, with class 1 being the highest. Prior to this, violations were simply classified as Yes or No. If a 123 classification has been assigned to a violation that occurred before this date, that classification data will be displayed instead of the Yes/No data.
