The King County Metro Transit Ryerson Base at 1220 Fourth Ave S in Seattle has operated as a municipal transit maintenance facility, with contamination discovered during a Hydraulic Lifts Replacement Project in Bay 6. Soil sampling conducted in December 2014 identified petroleum-contaminated soil classified as WDOE Category 3, along with lead concentrations of up to 21.3 mg/Kg, consistent with long-term vehicle maintenance operations. Wood pilings with a creosote-like odor were also observed on the property, further indicating an older, established facility. Soil excavation and waste profiling for disposal are underway as part of the cleanup. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
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 and lead contamination at this transit maintenance base is consistent with decades of vehicle fueling and servicing operations that predate 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Lead levels in the soil point to an era when leaded gasoline was standard — placing the contamination origin squarely within the pre-1986 policy window. The remediation costs already incurred and still ahead — excavation, soil profiling, regulated disposal — represent expenditures that historical carriers who covered the facility during those earlier decades of operation may be obligated both to recover and to fund going forward.
