Financial responsibility for oil spills

We require tank vessels, including small barges and commercial cargo/fishing/passenger vessels, to have financial responsibility. This means they are able to pay for the costs and damages of a spill up to a specified amount.


What is financial responsibility?

Financial responsibility refers to the proof or demonstration that a responsible party is able to pay for the costs and damages of a spill up to a specified amount. Typically, financial responsibility is evidenced by an insurance policy or Pollution and Indemnity (P&I) club documents, but also may involve surety bonds, guarantees, letters of credit, or qualification for self-insurance.

Financial responsibility requirements

Washington has financial responsibility requirements for vessels based on the vessel type, size, and the volume of fuel or cargo. Washington does not have its own certification program; we rely on federal and other state programs to certify vessels for financial responsibility.

On April 17, 2023, Ecology began a rulemaking to create a new rule, Chapter 173-187 WAC Financial Responsibility. The rulemaking will ensure that vessels and facility owners and operators have adequate financial resources to pay cleanup and damage costs arising from an oil spill. As part of this rulemaking, the existing Chapter 317-50 WAC – Financial Responsibility for Small Tank Barges and Oil Spill Response Barges, will be incorporated into the new rule and then repealed. For information about the rulemaking, visit our website at https://ecology.wa.gov/Regulations-Permits/Laws-rules-rulemaking/Rulemaking/WAC-173-187.
