During the month of September 2022, we had our historian go down for a period of 6 days. We have been attempting to recover data from the PLC for dates 9/6-9/11/2022 but are unable to do so. The lost reportable data includes:
UV Transmittance Average
UV Transmittance Maximum
UV Dose Average
UV Dose Maximum
We have alarm histories that are accurate as well as daily documented values for each one of these data points that have been reported. It would be a one-time read instead of a 24-hour max or average value.
|
We have added an alarm into our SCADA call out system that will notify us if or when the historian goes down. In addition, We will be installing a stand-alone system as a backup to help prevent any future incidents of lost data. |

To prevent further exceedances, Jacobs is running the centrifuge longer hours but at a lower flow rate. We have turned on our third aeration blower and are running it at 100%. In addition to the longer run hours and third blower running the City of Clovis has reduced flows to the facility down to 1.6 MGD as a daily average.
The Centrifuge is scheduled to be repaired early August. While the centrifuge is being repaired, we will have a belt press rental on site to prevent excessive inventory in our aeration basins. Jacobs and the City of Clovis will collaborate together and determine the best time to repair the diffusers.

Turbidity Instantaneous Maximum limit is .5 NTU and reported value was .92 NTU at FIL-001. *** MMP Exempt Reason:Not an effluent violation. It is an other violation type and considered Order Condition violation. |
The high turbidity event may have been caused by the two membrane tanks being in standby for an extended period of time and not being recirculated prior to pumping to the filtrate header. A rung of programming code was found that could have potentially allowed filtration directly following an extended standby period. An inhibitor was previously added to the filtration logic code, but found that logic triggering "Normal Filtration" did not include the inhibitor. 5 minutes of standby has been added to the inhibitor code of the "Normal Filtration" logic to assure the filtrate pump will not run directly after an extended standby period unless 10 minute recirculation has completed. |

Chlorine, Total Residual Instantaneous Maximum limit is .01 mg/L and reported value was .05 mg/L at EFF-A. *** MMP Exempt Reason:According to the discharger no chlorinated effluent was discharged from the facility. This is a violation of order condition not an effluent violation. |
A sample was taken from the recycled water tank at 9:46 AM and the result was <0.0015 mg/L . Please note that no chlorinated effluent was discharged from the facility. |
