Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1951. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This University Way NE property hosted Lee Hong Laundry, a dry cleaning operation, from 1951 to 1966, with tetrachloroethylene (PCE) used in its machinery and detected in sub-slab soil gas at concentrations exceeding regulatory guidelines — with evidence of migration into the southern building subsurface. The property also contained an approximately 1,800-gallon heating oil underground storage tank in use from roughly 1945 through the time of investigation, contributing petroleum hydrocarbon contamination. Remediation under Standard Cleanup included UST removal and triple rinsing, off-site disposal of VOC-contaminated soil and investigation-derived waste, and planned vapor suppression during subsequent redevelopment activities, culminating in a No Further Action determination by Ecology. 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 PCE contamination documented here originated from dry cleaning operations conducted at this site from 1951 through 1966 — activities that predate the 1986 threshold by at least two decades, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The heating oil UST, installed around 1945, adds a second independent pre-1986 contamination source tying historical carriers to the cleanup liability. The documented remediation expenditures — tank removal, soil excavation, waste disposal, and site investigation — were incurred to address releases directly traceable to those pre-1986 operations, and historical CGL carriers who issued policies during the dry cleaning and heating oil storage years may still be obligated to recover those costs.

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.

What We Look For

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.
