This property has a documented history as a industrial and manufacturing facility going back to 1962. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This 35-acre organic chemical manufacturing facility was constructed in 1962 and has been in operation since at least 1971, producing food preservatives, flavors and fragrances, plasticizers, and pharmaceuticals using toluene as a primary feedstock. The plant was operating as a recognized dangerous waste management facility by 1980, and contamination identified in 1989 and 1994 was attributed to those historical manufacturing operations. Cleanup work has included soil vapor extraction, groundwater treatment through trenches, recovery wells, and a wastewater treatment system, and multi-phase excavation and removal of mixed material solids from 2020 through 2022. Ongoing monitoring, remedial investigations, and institutional controls through deed restrictions remain active. 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.
Chemical manufacturing operations at this site began in 1962 — more than two decades before 1986 — when occurrence-based Commercial General Liability policies were still standard and carried no effective pollution exclusion in Washington. The contamination documented here in 1989 and 1994 traces directly to those pre-1986 decades of organic chemical production and the handling of toluene and associated industrial hazardous substances. The site's remediation record — vapor extraction infrastructure, groundwater recovery systems, multi-year excavation campaigns, and ongoing institutional controls — represents cleanup expenditures that historical CGL carriers whose policies were in force during those operational years may be obligated both to recover and to fund going forward.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
