This property has a documented history as a property with a heating oil tank going back to 1973. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Silver Beach Elementary School property used underground storage tanks to supply fuel oil to the building's boiler system; two USTs were removed in 1998 after petroleum contamination was discovered during site work. In 2013, remediation continued with the excavation and offsite thermal desorption of approximately 160 tons of petroleum-contaminated soil and the removal of associated fuel-supply piping, with the excavated area subsequently backfilled with compacted clay as a subsurface barrier. The site remains enrolled in the Standard Cleanup program with cleanup ongoing. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
Why Historical Insurance Policies May Be Accessible
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.
The heating oil USTs at this school property were installed and operated for decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. Historical carriers who issued CGL policies during that operational window may be obligated both to recover costs already documented — the 1998 tank removals and the 2013 soil excavation and thermal treatment — and to fund the continuing remediation obligations the property owner carries under the active Standard Cleanup program. Because cleanup here is not yet complete, the exposure to those historical carriers runs to future expenditures as well as past ones.
