Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1977. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Cascade Dry Cleaners has operated adjacent to this property since 1977, and a Phase II Subsurface Soil and Groundwater Investigation attributed trace concentrations of trichloroethylene (TCE) in groundwater at the site to the dry cleaning solvents used at that neighboring facility. Washington State Ecology issued an Early Notice Letter to Cascade Cleaners designating the site for suspected contamination under Standard Cleanup. To date, investigative work has been limited to the Phase II investigation itself — the only cleanup-related activity on record is the abandonment of investigation borings — and no active remediation has commenced. 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 the adjacent Cascade Dry Cleaners began in 1977, nearly a decade before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion in Washington. TCE contamination attributed to long-running dry cleaning solvent use is precisely the type of gradual, continuing release those pre-1986 policies were written to cover. The investigation and remediation costs the responsible parties now face — site characterization, cleanup design, and active remediation yet to come — represent expenditures that historical carriers whose CGL policies were in force during the contaminating operations may be obligated to fund.

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.
