Auto Body cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a auto body / repair shop going back to 1967. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a machinery storage, maintenance, and rental facility since at least the late 1960s, with vehicle fueling, steam cleaning, and heavy-equipment servicing among its core activities. Cleanup work under Ecology's standard program has spanned from 1989 to at least 2015, including removal of eight underground storage tanks, excavation and offsite disposal of at least 540 cubic yards of contaminated soil, in-situ bioremediation of groundwater, and multi-year monitoring campaigns with numerous wells and soil borings installed across the property. Remediation is ongoing. 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.

Petroleum contamination at this site originated from underground storage tanks, an engine sump, and a transmission sump tied to machinery maintenance operations that were already active when the facility was first reported to Ecology in 1969 — nearly two decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. More than 25 years of documented remediation expenditures — tank removals, large-scale soil excavation, bioremediation, and long-term groundwater monitoring — were incurred to address releases from those pre-1986 operations. Historical carriers who issued CGL policies during that operational window may be obligated both to recover past cleanup costs and to fund the remediation work that continues today.

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.
