Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Goodwill Corp Dearborn Campus has a documented industrial history extending to the late nineteenth century, with a laundry and dry cleaning facility confirmed by 1950 and 1969 Sanborn maps to have operated within the main Goodwill Building from the 1950s through 1997. The 2007 environmental report identifies tetrachloroethylene (PCE) and its degradation products — trichloroethylene (TCE), cis-1,2-dichloroethylene (cis-1,2-DCE), and vinyl chloride — along with chromium as chemicals of concern, attributable to those dry cleaning operations and to historical auto body and plating activity on the property. Underground storage tanks were also present and removed in the early 1990s, and cleanup work under the Standard Cleanup program is 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 campus began in the 1950s — more than three decades before 1986 — when occurrence-based Commercial General Liability policies were industry standard and contained no effective pollution exclusion in Washington. The persistent, widespread groundwater contamination from PCE and its chlorinated degradation products reflects a diffuse, slow-release profile tied directly to those pre-1986 solvent operations. Historical carriers who issued CGL policies during the decades of active dry cleaning and industrial use at this property may retain an obligation to fund the ongoing remediation costs.

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.
