Advance Notice of Oil Transfer (ANT)

The Advance Notice of Oil Transfer (ANT) system was developed as part of the implementation of rules related to the transfer and movement of oil in Washington State.

The preferred method for submitting the advance notice of transfer (ANT) is by web-based form which satisfies both Ecology and United States Coast Guard (USCG) reporting requirements for the advance notice of oil transfer. Facilities, vessels, and eligible emergency response agencies using this system must first register via the state’s SecureAccess Washington (SAW) online system at https://secureaccess.wa.gov/. This system will ensure protection of proprietary transfer information. After registration has been approved, ANTs may be submitted or viewed at https://secureaccess.wa.gov/ecy/ants.

Rule Information

The ANT System is used to submit and view advance notice details described in the following chapters of the Washington Administrative Code (WAC).

Chapter 173-180 WAC, Facility Oil Handling Standards and Chapter 173-184 WAC, Vessel Oil Transfer Advance Notice and Containment Requirements

These rules require submission of an Advance Notice of Oil Transfer (ANT) by the delivering facility (fixed or mobile) or vessel which is transferring over 100 gallons of bulk oil to a non-recreational vessel or facility. The ANT must be submitted 24 hours prior to the transfer for facilities, and as required by local USCG Captain of the Port requirements for vessels. Smaller fueling stations that deliver oil to non-recreational vessels with an oil capacity of less than 10,500 gallons are not required to submit the ANT form. Instead they must submit bi-annual reports detailing cumulative types and amounts of oil. See WAC chapters 173-184-100, 173-180-215, and 173-180-210 for details.

Chapter 173-185 WAC, Oil Movement by Rail and Pipeline Notification (adopted Aug. 24, 2016)

Facilities in Washington that receive crude oil by rail are required to submit advance notice for each new shipment of crude oil scheduled for delivery. Advance notice should be submitted before a crude-by-rail shipment scheduled for delivery in Washington enters the state. The ANT System was updated in 2016 to facilitate the requirements of Chapter 173-185 WAC, which also includes an interface for emergency response agencies to view rail oil transfer details in advance of the transfer. See WAC 173-185-070 and WAC 173-185-090 for details.
