Dry Cleaner cleanup site — Restorical Research

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1936. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has a dual operational history: it served as a retail fuel sales station from at least 1936 until approximately 1955, after which dry cleaning businesses operated on the site through approximately 2021, using perchloroethene (PCE) in their cleaning operations. Cleanup work under the Voluntary Cleanup Program has included excavation and removal of a 1,000-gallon heating oil underground storage tank and multiple exploratory excavations, with multi-year site characterization ongoing from 2022 through 2025. Groundwater monitoring has been recommended as remediation continues. 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 property — petroleum hydrocarbons from the gas station era and PCE from six decades of dry cleaning — originated from operations that began as early as 1936, spanning the entire period when occurrence-based Commercial General Liability policies were in effect without meaningful pollution exclusions. Historical carriers who issued CGL policies to operators at any point before 1986 had no effective exclusion for these slow, ongoing releases and may remain obligated today. The site's documented remediation expenditures — tank removal, soil excavation, multi-year characterization, and projected groundwater monitoring — represent costs that historical carriers may be liable both to recover and to fund as cleanup advances.

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.
