Public Works cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1980. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property served as the Chimacum School District's bus maintenance and fueling facility, with a fueling system — including five underground storage tanks and a fuel dispenser island — constructed in the early 1980s. Cleanup under the Voluntary Cleanup Program has included the excavation and removal of four USTs, fuel pumps, and 649 tons of contaminated soil between 1999 and 2000, along with the recovery of 2,600 gallons of petroleum-affected groundwater. A fifth waste-oil UST was closed in place. Monitoring wells were installed in 2002, and groundwater monitoring with remedial injections has continued through 2025; the property remains in active use as a bus barn. 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 traces to underground storage tanks installed and operated during the early 1980s — years when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. More than two decades of documented remediation expenditures — tank removals, large-scale soil excavation, groundwater recovery, well installation, and ongoing injection treatments — were incurred to address releases from those pre-1986 fueling operations. With cleanup still underway, historical carriers who issued CGL policies covering the school district's operations during that window may be obligated both to recover past costs and to fund the remediation work ahead.

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.
