Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1962. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Mac's One Hour Cleaners has operated as a dry cleaning facility on this Renton property since the 1960s, when the northern building housing the operation was constructed in 1962. Tetrachloroethene (PCE) from those historical dry-cleaning operations has contaminated soil and groundwater beneath the property; PCE concentrations currently exceed the MTCA Method A cleanup level by one to two orders of magnitude. Remediation — designated as an Independent Action by Ecology — has been underway since at least 2011, encompassing trench excavation, installation of an infiltration gallery, 1,010 pounds of HRC and HRC-Primer injections for in-situ bioremediation in May 2014, and multi-year groundwater monitoring with additional wells installed as recently as April 2016. Cleanup work 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 site trace to the 1960s, placing the origin of the PCE contamination firmly in the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The slow, subsurface migration of PCE — a hallmark of historical dry-cleaning releases — is precisely the type of continuing loss those pre-1986 policies were written to cover. Historical carriers who issued CGL policies during that operational window may bear obligations both to fund the ongoing bioremediation and monitoring and to recover costs already incurred through more than a decade of active cleanup work.

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.
