Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1966. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as Ken's Skyway Cleaners, a retail dry cleaning facility, from approximately 1966 through 2005, during which chlorinated solvents used in the cleaning process contaminated soil and groundwater beneath the site. Remediation has included multi-year groundwater monitoring from 2001 to 2013, waste management of purged groundwater, and operation of a soil vapor extraction and air sparging system in 2006 and 2007. Future remedial actions under a consent decree will encompass a Remedial Investigation, Feasibility Study, and implementation of a Cleanup Action Plan. 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 site began approximately two decades before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. The chlorinated solvents identified here — PCE, TCE, DCE, and vinyl chloride — are the products of slow, ongoing releases characteristic of decades of solvent use, precisely the contamination profile those pre-1986 policies were written to address. Historical carriers whose policies were in force during Ken's Skyway Cleaners' operational years may be obligated both to recover documented expenditures already incurred and to fund the investigation and cleanup work required under the consent decree 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.
