Unauthorized Discharge |
On October 28, 2024, a PG&E gas crew was in the process of assessing and repairing a natural gas line suspected of leaking at the PG&E Cupertino Service Center when a 3-in potable water line was accidentally struck and began to slowly leak. A plumbing contractor was then scheduled to repair the leak the following day. To access the leaking pipe for repairs, the excavation had to be dewatered. While water was discharged as an Unplanned discharge under the provisions of the General Order, required BMPs to filter the water prior to discharge were not implemented. The contractor performing the repair was not aware of PG&E's dewatering requirements and discharged the water without notifying PG&E Environmental staff or applying a filter sock prior to discharge. Water was pumped directly from the excavation and onto the ground where it flowed approximately 700 feet north along the facility's stormwater drainage swales and into the storm drains. |
