This property has a documented history as a industrial and manufacturing facility going back to 1957. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Upper Baker River Generating Plant, owned by Puget Sound Power & Light Company, operated as a hydroelectric facility in Concrete, Skagit County, with fuel dispensing and used oil storage serving as ancillary functions supporting its power generation operations. Underground storage tanks at the site were installed beginning in 1957, with additional tanks added in 1968 and 1978, including at least one leaded gasoline tank. Remediation has included removal of multiple USTs, excavation and stockpiling of approximately 30 cubic yards of contaminated soil, demolition of the on-site fuel house, soil processing and screening, and proper disposal of 80 gallons of purge and decontamination water; groundwater monitoring programs ran from 1992 through 1994 and are recommended to continue on an annual basis. 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.
Contamination at this property traces to underground storage tanks first installed in 1957 and operated by Puget Sound Power & Light Company for nearly three decades before 1986 — the year occurrence-based CGL policies ceased to provide reliable pollution coverage. The presence of leaded gasoline tanks and long-term used oil storage reflects the kind of slow, continuous release those pre-1986 policies were written to address. The documented remediation costs — UST removals, soil excavation, fuel house demolition, and ongoing groundwater monitoring — represent expenditures that historical carriers who issued CGL policies to the operator during that pre-1986 window may be obligated both to recover and to fund going forward.
