Spill response plans for Class 2 mobile facilities
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.
Spill response plans tell owners and operators of oil-handling facilities how to manage an oil spill incident. We also require mobile facilities to prepare oil-transfer response plans for their operations.
A spill response plan prepares a facility owner or operator to respond to an oil spill. There are both federal and Washington state requirements for oil spill response plans. We require an approved response plan for all Class 2 facilities operating in Washington.
Federal response plans for marine transportation-related facilities are required and regulated by the U.S. Coast Guard. Facilities often elect to develop one plan to address both federal and state requirements in the same document, but the two regulations function as separate programs.
Class 2 facilities must prepare and submit an facility response plan at least 90 days prior to conducting the first transfer operation to a non-recreational vessel.
We review and approve Class 2 response plans. Our approvals are valid for five years. Facilities with an expiring approval must submit an updated plan for re-approval, or a letter asking us to review and re-approve the existing plan, at least 90 days before expiration.
