Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1970. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has served as an industrial coatings and metal fabrication facility since at least 1970, with operations including sandblasting, painting, welding, and applying industrial coatings for corrosion control. Underground storage tanks installed prior to 1986 were removed in 1987, and cleanup activities since then have included excavation of significant volumes of petroleum- and metals-impacted soil, and operation of an air sparging system for groundwater treatment from 2004 through 2006. Additional remediation is planned, including further soil excavation, an air sparging and soil vapor extraction system, engineered controls, and monitored natural attenuation. 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.

Contamination at this site — heavy metals including chromium and lead, volatile organic compounds from industrial solvents, and petroleum hydrocarbons — originated from coating, blasting, and fabrication operations that were underway more than a decade before 1986. Occurrence-based CGL policies issued during that pre-1986 operational window carried no effective pollution exclusion under Washington law. The remediation expenditures already incurred since 1987 and the substantial cleanup costs still ahead — vapor extraction, engineered controls, long-term monitoring — represent obligations that historical carriers may be required both to reimburse 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.
