Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1940. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

The Mount Baker Cleaners dry cleaning operation has occupied this Seattle property since 1940, using tetrachloroethylene (PCE) and trichloroethylene (TCE) throughout its history and continuing to operate as a dry cleaning business today. The site also hosted a gas station beginning in 1955, with underground storage tanks removed in 1989 and 2005 and a third tank closed in place in 2011. Remediation under the Voluntary Cleanup Program has included groundwater treatment via ozone injection and in-situ chemical oxidation from 2005 to 2007, demolition of a retail building in 2018, completion of a Remedial Investigation/Feasibility Study in 2019, and a Cleanup Action completed by 2023, with post-cleanup controls and monitoring now 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.

Dry cleaning operations at this property began in 1940 — more than four decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. PCE concentrations as high as 3,700 micrograms per liter and TCE at 57 micrograms per liter in groundwater document the scale of contamination attributable to those pre-1986 operations. The documented remediation costs here — UST removals, groundwater treatment, a full RI/FS, a Cleanup Action, and continuing post-cleanup monitoring — represent expenditures that historical carriers who issued CGL policies during the facility's early decades may be obligated both to recover 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.
