Preliminary Site-Specific Analysis

This property has a documented history as a property with a heating oil tank going back to 1970. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property was developed as a 7-Eleven convenience store in the 1970s and has since become unoccupied. A Phase II Environmental Site Assessment identified oil-range petroleum contamination in groundwater at concentrations exceeding MTCA Method A cleanup standards. The site has been added to Washington State's cleanup database and is enrolled in the Voluntary Cleanup Program as Awaiting Cleanup; no remediation work has yet 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.

Commercial buildings constructed in the 1970s routinely relied on heating oil systems, and the 7-Eleven building's decade of pre-1986 operation places it squarely within the era when occurrence-based CGL policies were the industry standard and carried no effective pollution exclusion in Washington. The oil-range petroleum now detected in groundwater represents precisely the kind of slow subsurface release those policies were written to address. Investigation, remedial design, and cleanup costs the property now faces could plausibly be recovered from historical carriers whose policies were in force during the building's decades of pre-1986 operation.

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.
