Title | Offsite Notification of Potential Oil Discharge |
Event Description | On August 22, 2021, Columbia Generating Station determined that no more than approximately eight (8) gallons of silicone oil was inadvertently released into a plant service water system due to a failed heat exchanger on a plant installed air compressor. The plant service water system returns water to a water basin that contains at a minimum 300,000 gallons of water. The water basin is connected to the Columbia River via a blowdown line. Although not confirmed, it is suspected that an unknown quantity of silicone oil may have been released to the Columbia River. A visual inspection of the basin did not identify any oil sheen or film, and there are no additional actions needed to mitigate this issue. It does not appear the oil release poses a threat to human health or the environment, however because there could have been a discharge of an unknown quantity of silicone oil into the Columbia River this matter is immediately reportable under RCW 90.56.280 to the US Coast Guard National Response Center and Washington State Department of Ecology.
This condition is being reported pursuant to 10 CFR 50.72(b)(2)(xi) for news release or notification of other government agencies concerning an event related to the health and safety of the public or protection of the environment. Notifications to off-site agencies were performed at 1825 PDT on 8/23/2021. The NRC resident has been informed. |
