Dry Cleaner cleanup site — Restorical Research
NW Market Street
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

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

This Seattle property is the site of historical dry cleaning operations that left tetrachloroethene (PCE), trichloroethene (TCE), benzene, petroleum hydrocarbons, and metals in soil and groundwater at concentrations exceeding MTCA cleanup levels. Cleanup Action Plans were issued in 1999 and 2000, and a Restrictive Covenant was recorded against the property in 2001. Remediation to date has included installation of an iron groundwater treatment wall, with planned future work encompassing removal of existing buildings and foundations and remediation of soil contamination, along with continued monitoring, sampling, and compliance obligations. 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.

The contamination profile at this property — chlorinated solvents, petroleum hydrocarbons, and metals spread across soil and groundwater — reflects long-term operational releases, not a single recent event, placing its origins squarely in the pre-1986 era when occurrence-based CGL policies were standard. Cleanup Action Plans dating to 1999 and 2000 and a 2001 Restrictive Covenant document over two decades of regulatory-mandated remediation costs already incurred, while the iron treatment wall, planned building removal, and ongoing monitoring ensure that expenditures will continue to grow. Historical carriers whose policies were in force during the decades of dry cleaning operations that produced the PCE, TCE, and petroleum contamination at this site may be obligated to fund both the costs already spent and those still ahead.

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.
