This property has a documented history as a gasoline service station going back to 1948. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The DSHS S Graham St property at 3600 S Graham St carries petroleum contamination traced to historical releases from two adjacent former gas stations on Martin Luther King Jr. Way — one involving former waste oil underground storage tanks at 6061 MLK Jr. Way, the other a gasoline station at 6007 MLK Jr. Way with operations dating to at least 1948. Site investigation identified oil, diesel, and benzene compounds in groundwater beneath the property. Remediation work at the site has included the removal of four 10,000-gallon underground storage tanks in 1989 and 1998, management of impacted soil stockpiles, and semi-annual to quarterly groundwater monitoring conducted since 1999; a 2001 air sparge feasibility test was cancelled due to site conditions, and no final cleanup has yet commenced. 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 petroleum releases that contaminated this property originated from adjacent gas station operations predating 1986 — including a station at 6007 MLK Jr. Way active since at least 1948 and USTs that stored leaded gasoline, confirming decades of pre-1986 operations. Occurrence-based Commercial General Liability policies issued to those adjacent operators during that era carried no effective pollution exclusion and remain enforceable. The investigation and monitoring costs already incurred at this site, and the remediation expenditures still ahead, represent potential claims against the historical carriers whose policies were in force when those releases first occurred.
