This property has a documented history as a automobile dealership going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Riley Parking Lot in Tacoma is contaminated by petroleum hydrocarbons — weathered gasoline and kerosene — traced to an adjacent property to the west that has operated as a car dealership and auto repair service center since at least 1930. Site investigations in 2004 and 2008 confirmed the contamination, and the weathered character of the gasoline strongly indicates the original release predates those assessments by a substantial margin, pointing to a pre-1986 origin. In 2007, remediation activities removed the asphalt surface and excavated 85 tons of contaminated soil for off-site disposal; cleanup at the property continues under the Standard Cleanup program. 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 contamination here originated from auto dealership and service operations conducted decades before 1986, when occurrence-based CGL policies were still the industry standard and carried no effective pollution exclusion. The 2007 remediation — excavation and off-site disposal of 85 tons of impacted soil — represents documented past expenditures that historical carriers whose policies were in effect at the time of the original release may be obligated to reimburse. Beyond those recoverable sunk costs, cleanup at this property remains ongoing, meaning those same pre-1986 insurers may also be obligated to fund the continuing remediation work going forward.
