Preliminary Site-Specific Analysis

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.

This property received waste oil and sludge from a former used oil recycling facility located across 26th Place South beginning in the mid-1980s. A 1989 cleanup action uncovered numerous buried drums at the site, indicating sustained dumping over a period of years. Contaminants identified include halogenated organics, metals, and petroleum products. The site entered the Voluntary Cleanup Program and has since received a No Further Action determination, with a periodic review completed in 2015. 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.

Waste disposal activities that generated contamination at this property began in the mid-1980s — within the window when occurrence-based Commercial General Liability policies were still standard and carried no effective pollution exclusion. The discovery of numerous buried drums during the 1989 excavation points to sustained operations over multiple years, strengthening the case that contamination-generating activity was underway before 1986. Remediation costs incurred under the Voluntary Cleanup Program to address halogenated organics, metals, and petroleum contamination at this site may be recoverable from historical carriers whose CGL policies were in force during that operational period.

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.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
