Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1917. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Seattle property has hosted continuous commercial and industrial operations since before 1917, with successive tenants including York Construction & Supply, Alaska Barrel Company, Perry Brothers wholesale poultry, and Chasen City Floor Company spanning decades of use through the 1980s. Oil-heated buildings and underground storage tanks were installed circa 1950; the USTs were not removed until 1991 and 1993. An independent remedial action investigation documented tetrachloroethylene (PCE) and vinyl chloride in groundwater at concentrations exceeding MTCA Method A cleanup levels, and while total petroleum hydrocarbons in groundwater have been addressed to standards, Ecology's 2012 opinion letter confirmed that further remedial action for PCE and vinyl chloride is still required. 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.

Industrial and commercial operations at this property began more than six decades before 1986, the year occurrence-based CGL policies gave way to claims-made forms with absolute pollution exclusions. The groundwater contamination now requiring further remediation — PCE and vinyl chloride, both hallmarks of industrial solvent use — traces to operations conducted under policies that had no effective pollution exclusion in Washington. Documented remediation expenditures to date and the cleanup costs still ahead represent obligations that historical carriers who insured these pre-1986 operations may be required 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.
