This property has a documented history as a industrial and manufacturing facility going back to 1907. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This property operated first as a steam plant beginning in 1907 and then as a manufactured gas plant (MGP) from 1913 to 1947, with steam plant operations continuing until 1959. MGP processes used high-temperature conversion of coal or petroleum-based materials into combustible gas, generating coal tar as a waste product now identified as the primary source of contamination at the site. Coal tar was discovered in 2018 during an investigation of an adjacent property, triggering ongoing environmental investigations, quarterly groundwater monitoring events from 2022 through 2024, and a physical containment action — installation of a 10-foot bentonite seal to prevent downward migration of coal tar NAPL through the subsurface. Active remediation has not 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 coal tar contamination at this site originated from MGP operations that began in 1913 and ran for more than three decades — all of it before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. Coal tar is precisely the type of slow-migrating, long-latent industrial waste that pre-1986 policies were written to address: deposited over decades of operation, discovered only when a neighboring site investigation uncovered the plume. The costs now accumulating — multi-year investigation, quarterly monitoring, subsurface containment, and eventual remediation — could plausibly be funded by historical carriers whose policies were in force during the MGP-era operations that caused the release.
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.
