This bill amends existing law, RCW 64.06.090, by changing the seller disclosure required for residential real property that uses an oil tank for heating. The amendment requires the seller to provide a specific notice to the buyer about oil tanks used for heating and replaces the existing phrase about possible "no cost insurance" with language stating that "remediation assistance for heating oil contamination may be available" and directs the reader to contact the Washington State Pollution Liability Insurance Agency for more information. This is a procedural change to disclosure requirements rather than the creation of a new crime or a change in penalties. The bill also adds a new section stating it applies prospectively only and not retroactively, and it applies only to property sales arising on or after January 1, 2027. Affected parties identified include sellers and buyers of residential property that uses heating oil tanks and the Washington State Pollution Liability Insurance Agency. The extracted text does not include the full original RCW 64.06.090 language, does not define "remediation assistance for heating oil contamination," and does not show any other sections or an operative effective date beyond the stated prospective application; those details are therefore uncertain. The bill was referred to the Committee on Consumer Protection & Business.

Starting January 1, 2027, sellers of homes that use oil tanks for heating will be required to give buyers a specific notice saying that remediation assistance for heating oil contamination may be available and to contact the Washington State Pollution Liability Insurance Agency for more information. In practice this means sellers have a new, concrete disclosure duty and buyers will routinely be told where to seek help or information about oil‐tank contamination when considering a purchase. The people most affected are residential sellers (who must add this notice to their disclosures), buyers of properties with oil heat (who will get more information and may make more inquiries or be more cautious), and the Pollution Liability Insurance Agency (which is likely to receive more calls or requests for info). The bill does not define what “remediation assistance” includes or provide any new funding or eligibility rules, so it’s unclear what actual cleanup help would be available or who would pay for it.
