Confirmation of the existence of contamination or suspicion of contamination resulting from a spill or release of heating oil should prompt several pertinent questions:
- What reports must be made, and to whom?
- When does a cleanup have to occur?
- What is the required level or standard of cleanup?
Heating Oil Fact Sheet
The Pollution Liability Insurance Agency (PLIA) has created this Heating Oil Fact Sheet to provide an overview on how to address heating oil releases and to describe PLIA’s heating oil programs. Please contact Jeremy Richtmyre if you have additional questions.
PLIA conducts Initial Investigations of heating oil tank releases referred to us by the Department of Ecology. During an Initial Investigation we gather information to determine if a cleanup is required under the Model Toxics Control Act, the state’s cleanup regulation.
Owners or operators of heating oil tanks should report releases to the Department of Ecology office located in the region where the release occurred within 90 days of discovery.

If you believe the release is a threat to the environment or needs immediate action, please contact the Department of Ecology’s Spills Program, or your local health department. If the release has impacted surface water or groundwater (e.g. lakes, rivers, creeks, or storm sewers), you must also notify the Washington Emergency Management Division at 1-800-258-5990.
Chapter 173-340 WAC (Model Toxics Control Act – Cleanup) addresses the requirement for cleanup of contamination and the requirement to conduct remedial action necessary to protect human health and the environment.
If a cleanup is required, you can apply for technical assistance under our Heating Oil Technical Assistance Program.
If contamination from a spill or release from a heating oil tank does not pose an imminent or substantial threat to human health and the environment, cleanup does not have to be accomplished immediately.
You should keep a copy of all documents related to a heating oil tank cleanup, including copies of any lab analyses. We recommend you take photos throughout the process.
