Order Conditions |
December 23, 2021, an unauthorized discharge occurred due to very high effluent flows which dislodged a temporary plug in a corroded automatic relief valve nozzle at the ARV#6 vault. The initial estimated unauthorized discharged quantity of 40-45,000 gallons reported to all required parties. The final discharge quantity of 158,400 gallons was reported in the 5-day report. The discharge took place over an 8-hour period. During this 8-hour period the discharge occurred at effluent flows above 37MGD for 5.5-hours. |

Order Conditions |
The week of December 13, 2021, the Monday through Friday average effluent flow was 25.59 MGD with effluent flow peaks up to 50 MGD (normal average dry weather flows of 9 MGD). It is assumed but has not been confirmed that utilization of the final effluent storm pumps to handle the increased flows resulted in a discharge from an unknown location on the outfall pipeline between the final ARV#6 and the bay discharge. On December 16, 2021 water lightly bubbled up out of the soil near the ARV#6 vault into a curbed planter box and then onto a dirt utility road. An estimated 300 gallons was reported to all required parties. |
