This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
Western Towboat Co operated a marine industrial facility at 3956 NW 6th Avenue in Seattle, where petroleum hydrocarbons were released into soil and groundwater during those operations. Environmental assessments began in 1989, and independent remedial actions — including bioremediation testing — were carried out under the Voluntary Cleanup Program over the following decade. Ecology issued a No Further Action determination for the site in 1999. 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 hydrocarbon contamination at this property is historical in character — no evidence of a recent release was identified, and the releases that drove more than ten years of remediation almost certainly predated 1986. Occurrence-based Commercial General Liability policies issued to Western Towboat Co's operators during that pre-1986 window carried no effective pollution exclusion and remain enforceable today. Historical carriers whose policies were in force during the operational window may be obligated to recover the documented costs of investigation, bioremediation, and long-term assessment.
Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.
Recovering Costs from an Older Cleanup
If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.
