Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1980. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This commercial property carried two separate contamination histories. A Unocal/Arco service station operated on the site in the 1980s, releasing petroleum that was reported in the 1990s, remediated under the Standard Cleanup program, and closed with a No Further Action letter in 2005. Best Drycleaners has leased space at the property since 2007, using and storing tetrachloroethene (PCE/PERC) without secondary containment; a Phase II investigation confirmed a PCE release at concentrations exceeding regulatory cleanup levels. Hazardous waste materials were also removed from the property prior to a 2016 ownership change. 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 Unocal/Arco service station at this property operated during the 1980s, a period when occurrence-based Commercial General Liability policies remained the industry standard and carried no effective pollution exclusion in Washington. Historical carriers who issued CGL coverage to the service station's operators during the pre-1986 portion of that operational window may remain obligated to contribute to the documented petroleum cleanup costs at this site. The confirmed PCE release from the dry cleaning operation — at concentrations still exceeding cleanup standards — compounds the remediation liability trail and strengthens the case for a full insurance-archaeology review of all policies tied to this property's multi-decade contamination record.

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.
