Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1983. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

Mount Baker Cleaners has operated as a dry cleaning business at this Seattle location since 1983, using tetrachloroethylene (PCE) and related chlorinated solvents throughout its operation. Contamination was identified in 2009, with compliance actions addressing floor staining and improper chemical storage taken in 2010. A Prospective Purchaser Consent Decree, initiated in 2016 and amended in 2017 and 2018, is now the governing framework for site cleanup in connection with redevelopment. The dry cleaning business remains in active operation. 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.

Mount Baker Cleaners began operations in 1983 — three years before 1986, the year CGL policy language began systematically excluding pollution claims — meaning the PCE and TCE contamination traced to those early years of solvent use occurred squarely within the pre-exclusion window. Any carrier that issued an occurrence-based CGL policy to Mount Baker Cleaners between 1983 and 1986 may be obligated to contribute to the remediation costs now being pursued under the Consent Decree. The active dry cleaning use and ongoing cleanup obligation mean those historical policy obligations remain live 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.

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.
