The Commercial Underground Storage Tank Reinsurance program was created by the Washington State Legislature in 1989 and began operations in September of that year.
The Legislature found that many owners and operators of underground storage tanks (USTs) could not purchase pollution liability insurance because:
- private insurance was unavailable at any cost, or
- owners and operators could not meet the rigid underwriting standards of existing insurers.
PLIA was established to provide affordable pollution liability insurance that helps owners and operators comply with the financial responsibility regulations of the Environmental Protection Agency (EPA) and the Washington State Department of Ecology.
