Unauthorized Discharge |
On 23 July 2022 Board staff received a Spill Report #22-4181 from the Office of Emergency Services (OES) describing a spill that occurred between the hours of 6 PM Friday 22 July 2022 and 6 AM Saturday 23 July 2022. CDCR staff submitted a Spill Notification Report on 25 July 2022 with further details, pictures, and a map of the spill. CDCR staff stated in that report that a power failure/surge tripped the uninterruptible power supply (UPS) to enter alarm mode and then fail to reset. This caused the Supervisory Control and Data Acquisition (SCADA) system to crash, halting operation of the wastewater treatment plant. However as wastewater continued to flow into the plant causing the effluent basin to fill, eventually tripping a secondary high level alarm. Although the alarm called out it was not relayed to an operator by the Main Control group so the issue was not discovered until an operator arrived onsite following morning. CDCR reports that the effluent basin was spilling for 12 consecutive hour. Using historical SCADA data for the time frame of 6 PM to 6 AM from the prior 5 days the CDCR operator estimated 160,830 gallons was released. This is value does not include any discharges of stormwater or comingled stormwater from the stormwater collection system of the Old Prison facility, which are currently being addressed through other enforcement actions. Because the treatment plant was no operating during this time and the volume exceeds that of the chlorine contact channel the discharged water consisted of partially treated wastewater. No samples were collected. The spill overtopped the effluent basin, flowed approximately 120 feet east to a culvert which leads under the road to a surface water drainage course that leads to Mule Creek. This is release of treated and partially treated wastewater is a violation of the WDRs. Relevant WDR Discharge Prohibitions and Discharge Specifications are cited below. On the morning of 23 July when the spill was discovered CDCR staff used a trailer mounted vacuum excavator to recover 8,500 gallons from the drainage. The operator provided a map showing the path and location of the spill as well as pictures prior to and after the cleanup effort in the Spill Notification Report. That map and the pictures are attached. All pictures were taken from the location designated as ?End of Spill? on the map. The Discharger states in the Spill Notification Report that CDCR intends to implement training procedures for their Main Control group to ensure the proper staff are notified when wastewater treatment and conveyance related alarms are triggered. |
