Title | Offsite Notification - Oil Release |
Event Description | The following information was provided by the licensee via email:
On 6/13/23 at approximately 1030 PDT, testing was being conducted on a lubricating oil system which interfaces with a cooling water system that has a pathway to the Columbia River. Due to an equipment failure, an indeterminate amount of oil leaked into the cooling water system, with a maximum potential loss of 300 gallons of oil. At 1230 PDT, an oil sheen was identified on the water basin which is the suction and discharge for this cooling system. The discharge pathway to the river was isolated at 1235 PDT. Investigation at the Columbia River showed no signs of oil sheen. This is being reported to offsite agencies under the Columbia Generating Station NPDES [National Pollutant Discharge Elimination System] Permit section S3.E.b. l and RCW [Revised Code of Washington] 90.56.280 due to the discharge of oil which has the potential to cause a sheen on the surface of the river. This condition is being reported pursuant to 10CFR50.72(b)(2)(xi) for news release or notification of other government agencies related to health and safety of the public or protection of the environment. Notifications to off-site agencies were performed at 1842 PDT on 6/13/2023. United States Coast Guard National Response Center Incident Report# 1369989. Washington State Emergency Management Division Report# 23-2245. Discharge pathway will remain secured until on-site cooling water system has been remediated. The NRC resident has been informed. |
