Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1967. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

Sternoff Metals Corporation operated a large-scale scrap metal and electrical equipment recycling facility at this property from approximately 1967 to 1985, processing automobiles, electrical wire, storage tanks, and PCB-containing transformers delivered by rail car through an industrial shredding and separation process. Remediation has proceeded under a Cleanup Action Plan that maintains engineered soil and surface covers over residual contamination and enforces institutional controls — including groundwater use restrictions backed by restrictive covenants recorded from 1997 onward. The site has reached No Further Action status under Washington's Standard Cleanup program. 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.

Nearly two decades of industrial recycling operations at this property — including the shredding and processing of PCB-laden transformers — concluded in 1985, one year before the 1986 threshold after which occurrence-based CGL policies began carrying effective pollution exclusions. The documented remediation record, from aluminum dross removal through a multi-decade Cleanup Action Plan with engineered covers and permanently recorded groundwater restrictions, reflects the scale of liability generated by those pre-1986 operations. Historical carriers who issued CGL coverage during Sternoff Metals Corporation's operational window may still be obligated to fund the costs tied to that contamination.

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.
