Blewett Pass, Washington diesel spill

US Hwy 97 | 2025-Apr-24

Initial Notification: On April 24, 2025, the EPA contacted the SSC to notify NOAA about a 50-gallon diesel spill on Blewett Pass in WA. The spill occurred several months ago (sometime between December 2024 and February 2025). EPA was just made aware of the spill. There does not appear to be an NRC notification associated with this release. The spill entered Tronsen Creek (which feeds into Peshastin Creek and ultimately the Wenatchee and Columbia Rivers). WAECY is planning on conducting a site visit next week. SSC notified NMFS. No further support has been requested.
