Preliminary Site-Specific Analysis

This property has a documented history as a facility using PFAS-containing firefighting foam going back to 1982. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Eastside Fire & Rescue Headquarters at 555 NW Holly St was constructed in 1982 and used aqueous film-forming foam (AFFF) in firefighting training activities from the early 1980s through the late 1990s. Those training activities contaminated soil and groundwater with per- and polyfluoroalkyl substances (PFAS), which have since been confirmed at the site and detected in the City's water supply. Cleanup is underway under the Standard Cleanup program, currently centered on a granular activated carbon treatment system filtering PFAS from the water supply, alongside management and disposal of investigation-derived waste including soil cuttings and contaminated water. The remediation is a multi-year effort with an estimated total cost of $221,802, with additional characterization and remediation tasks still planned. 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.

AFFF-based training at this facility began in the early 1980s, placing the contamination's origin firmly within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Repeated AFFF training exercises produced the type of gradual, accumulating release that pre-1986 CGL policies were structured to cover. The documented and projected expenditures here — groundwater treatment infrastructure, waste disposal, investigative work, and future remediation — represent costs that historical carriers whose policies were in force during those training years may be obligated both to recover and to fund going forward.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

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 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
