Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1981. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property housed a 1,100-gallon underground storage tank used for gasoline storage in support of its commercial dairy-supply and service-warehouse operations. The leaking UST was removed in April 2006, with soil and groundwater sampling confirming petroleum concentrations exceeding MTCA Method A cleanup levels. Cleanup activities to date include tank removal, excavation backfilling, and ongoing quarterly and semi-annual groundwater monitoring; natural attenuation is being evaluated as the long-term remedy, with institutional controls recommended. 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 underground storage tank at this property was installed approximately twenty-five years before its 2006 removal, placing its origin around 1981 — squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The gasoline and BTEX contamination found in soil and groundwater traces directly to that pre-1986 tank operation. Documented remediation expenditures already incurred — tank removal, site investigation, years of groundwater monitoring — along with the costs of any forthcoming cleanup could plausibly be recovered from and funded by historical carriers whose policies were in force when the release began.

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.
