This property has a documented history as a public works and maintenance facility going back to 1951. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property was originally constructed in 1951 as U.S. Army Nike Battery No. 37 and passed successively to the U.S. Air Force in 1961 and to the Washington Air National Guard in 1971. Hazardous materials were generated and disposed of on-site through vehicle maintenance, aerospace ground equipment maintenance, corrosion control, battery shop operations, and Nike Ajax missile maintenance. Cleanup included vacuum-truck removal of contaminated sediments, installation of an activated carbon treatment system at a nearby residential well, and injection of over 59,738 gallons of potassium permanganate for in situ chemical oxidation of groundwater between 2003 and 2005. The 2007 selected remedy — estimated at $195,000 — required relocation of a residential water supply well and recorded environmental covenants, and the site has since reached No Further Action status. 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 contamination at this property — 1,1-dichloroethylene attributable to historical 1,1,1-trichloroethane use — originated from military operations conducted continuously from 1951 through the pre-1986 period under three successive government operators. Occurrence-based Commercial General Liability policies issued during those Army, Air Force, and Air National Guard operational windows had no effective pollution exclusion and remain potentially enforceable today. The documented remediation record — multi-year investigations spanning more than a decade, large-scale groundwater chemical oxidation, residential well treatment and relocation, and environmental covenants — represents the cost trail that recovery efforts against historical carriers would draw on.
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.
