1082716 08/24/2020 CTOX Chronic Toxicity Monthly Average limit is 51 TUc and reported value was 59.2 TUc at EFF-001. Violation B Report
1078685 07/17/2020 CAT1 Total Suspended Solids (TSS) Weekly Average limit is 45 mg/L and reported value was 48.0 mg/L at EFF-001. The apparent cause of the high TSS values has been traced to an operational control problem with the Aeration System. The District monitors for Dissolved Oxygen at the end of the Aeration Basin maintaining a 2 mg/L Dissolved Oxygen concentration. The PLC that controls blower speed/output utilizes this setpoint input to determine the appropriate blower speed/output. On falling Dissolved Oxygen concentration, the PLC increases blower speed/output and vice versa. During the evening and early morning hours, when biological respiration is minimized from darkness, coupled with minimal diurnal load, the PLC control program for blower speed/output would reach a dead band. This dead band would take several hours to overcome and ramp up blower speed/output during the morning diurnal peak load to the treatment plant. This dead band resulted in too little air being applied to the Aeration Basin stressing the microbiology reducing the level of treatment. The Districts solution was to implement a PLC program change to eliminate the dead band. This programming change was implemented on July 24, 2020. The District believes this has eliminated the dead band issue. The District does not know why this dead band issue began to show up in July 2020. The blower system has been functioning adequately since 2010 with no significant changes. It is hypothesized that the predominant Shelter In Place requirements for the residents of Rodeo from the COVID 19 Pandemic has significantly changed the weekday makeup of the Sewage to the Districts Treatment Plant. Rodeo is primarily a "bedroom" community. The District has observed an approximate 10% increase in weekday flow to the Treatment Plant. Violation B 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.
