Other Violations/Staff Remarks:
Facility reported 13.95 inches of rain for the month of May 2020. Recorded 2.90 MGD of flow on 5/21/2020 due to heavy
rain event. Violations during month of May related to heavy rain events.
Facility is under SOC WQ S19-003 that cover parameters for Total Suspended Solids (Monthly Avg. 45.0 Weekly Avg.
70.0) and Fecal Coliform (Monthly Avg. 400*, Weekly Avg. 600*) *Geometric Mean.
Supervisor Remarks:
please clarify why there are so many "No action, Facility Reporting Errors". if there are violations
of the Soc, we will need to enforce the SOc stipulated penalties potentially. we may have some
discretion since the severe natural condition would be an act of God and be covered under the 4
exemptions in the Soc
