Amendments to Chapter 173-180 WAC and Chapter 173-184 WAC

Amendments to Chapter 173-180 WAC, Facility oil handling standards and Chapter 173-184 WAC, Vessel oil transfer advance notice and containment requirements were adopted on June 6, 2023. This webpage will be updated with new requirement information on the effective date for the respective requirements.

We have requirements for advance notice of oil transfers (ANT) to help prepare for and prevent oil spills to Washington's environment. Our rules establish requirements for bulk oil transfers over water, and for providing notice of crude oil being transported by rail and pipeline through the state.

Advanced notice of oil transfer helps us streamline compliance inspections for over-water transfers. It allows local emergency responders to prepare for oil-related incidents from rail and pipeline transport. We provide guidance to regulated businesses and vessels for submitting advance notice of oil transfer.

Emergency responders

The State Emergency Management Division, the Utilities and Transportation Commission, and any county, city, tribal, port, and local government emergency response agency can access data on rail shipments of crude oil that enter Washington. These users do not submit transfer notices but are authorized to view them. Please note: this information is exempt from public disclosure and cannot be shared with the public.
