No Fecal Coliform sample was taken on a Wednesday, and by permit, we must test both Total and Fecal Coliform on Wednesday and Saturdays.
Fecal Colifom was taken on Tuesday, 5/13 and Saturday, 5/17, and as always was <2 MPN/100 ml. |
This was human error. |

Daily Coliform sample was set up incorrectly by our Laboratory. Our permit requires 15 tube multiple fermentation, yet it was mistakenly set up as a Quanti-Tray. Although no coliform was detected, it is a violation because we have no MTF results for January 7, 2025. |
This event was due to error on the Laboratory's part. They have already changed their procedures to keep it from happening again. See letter from lab attached herein. |

This deficient monitoring violation occurred during an "atmospheric river" rain event which resulted in numerous closed roads around San Luis Obispo County. We were not able to deliver the coliform sample that day to an accredited laboratory due to the storm. |
This violation was caused by a natural event over which we had no control. |

Total Coliform Sample was not analyzed on this day. Flooding in County prevented delivery of sample to a certified Lab within the holding period of the sample, due to closed roads and highways. |
Since this was a natural event, there is no corrective action. |

Order Conditions |
This report concerns an unauthorized discharge that occurred at the Cayucos Water Resource Recovery Facility at 800 Toro Creek Road, Morro Bay, California on December 4, 2022. Partially treated wastewater flowed out of our Aeration Basins and Membrane Tanks and ran to a capture basin on-site. All the wastewater was captured and was re-treated.
During a period of rainy weather, one of our membrane tanks had a valve that failed to open. That valve failure shut down that Membrane Tank at 00:06 hours. We have determined that the reason for the valve failure was water in the electrical conduit, and have removed the water and re-sealed the conduit. The other two Membrane Tanks onsite were unable to keep up with influent flow, and also shut down, at 00:44 and 00:45 hours. One alarm was sent for each membrane tank failure. These alarms were not acknowledged by the operator on standby.
During the time that all three Membrane Tanks were offline the average influent flow was 424 gallons per minute. From 00:45 to 05:28 hours, the flow was 120,541 gallons. At 05:28 hours, influent flow was stopped by turning off influent pumps. These flows were abnormally high for that time of the night due to the ongoing rain event.
We pumped the overflow back from the capture basin to our Equalization Basin, where it was then sent back through the treatment system. The water was pumped to the Equalization Basin by end of day, Thursday, December 8th. The retreatment process was completed on December 15, 2022.
To prevent a reoccurrence of this unauthorized discharge, we completed the repairs on the Membrane Tank valve on December 8, 2022. We have also changed the number of alarms that the standby operator receives from one for a failure to multiple alarms to ensure proper notification and timely response.

A total of 130,785 gallons was recovered and reprocessed through the plant. This total includes washdown water. |
