This property has a documented history as a property with a heating oil tank predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This rural-residential property in Kingston came to regulatory attention through the discovery of an abandoned 55-gallon drum containing a mixture of pentachlorophenol (PCP) and diesel, along with a 100-gallon fuel oil storage tank that had been abandoned in an on-site shed. The property owner stated that the drum had been present for over 30 years as of December 2013, placing it on the property before 1983. Cleanup activities have included removal of the drum, and regulators have determined that additional remediation remains necessary under an Independent Action process. 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 contamination at this property — PCP and diesel from a drum stored on-site for decades — originated from a period well before 1986, when occurrence-based CGL policies were still the industry standard and carried no effective pollution exclusion in Washington. Long-term storage and slow release of PCP and diesel from a container in place since at least the early 1980s is precisely the kind of gradual pollution event those policies were written to cover. With additional cleanup still required, historical carriers whose policies were in force during the drum's storage period may bear an obligation both to fund ongoing remediation and to recover costs already incurred.
