Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup.

This property operates as a Grays Harbor County road maintenance shop in Cosmopolis. Two 4,000-gallon underground storage tanks were documented with a recorded installation date of January 1, 1989, though their single-wall steel construction, sacrificial anodes, and absence of under-dispenser containment sumps are design characteristics predating the 1988 EPA UST regulations. In 2021, both tanks were removed along with approximately 383 tons of contaminated soil at a permitted cost of $286,500; petroleum hydrocarbons, benzene, and halogenated solvents are suspected in groundwater, which was encountered at just four feet below ground surface during excavation. The site remains under active evaluation as a multi-year cleanup project, with no further remediation commenced beyond the 2021 removal action. 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 recorded tank installation date of January 1, 1989 falls after the 1986 threshold when occurrence-based Commercial General Liability policies typically gave way to claims-made forms with pollution exclusions. However, the tanks' physical characteristics — single-wall steel with sacrificial anodes and no under-dispenser containment — are inconsistent with post-1988 EPA standards and raise the question of whether fueling operations at this county facility began before the documented date reflects. If pre-1986 operations can be established, the remediation costs already incurred and the cleanup work still ahead at this site could fall within the coverage window of historical CGL policies issued during that earlier period.

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.
