Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1955. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

The Anacortes Refinery has processed crude oil into gasoline, diesel, jet fuel, and other petroleum products since its construction in 1955, with the Oily Water Sewer system in continuous operation from that same date. Documented waste disposal activities at the site run from 1971 through 1974, and by November 1980 the facility was operating as a Dangerous Waste Management Facility, including management of leaded tank bottoms. Current corrective actions center on the OWS system and include excavation of hazardous fill, groundwater monitoring, remediation planning, and multi-year financial assurance obligations. 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 contamination timeline here spans from the OWS system's 1955 construction through documented leaded tank bottom management in the early 1980s — a 30-year window during which occurrence-based CGL policies were in force at this refinery. Leaded tank bottom handling is itself an automatic pre-1986 qualifier, and the site's waste disposal record from the 1971–1974 period falls squarely within those policies' coverage window. The documented remediation expenditures — hazardous fill excavation, groundwater investigation and treatment, and ongoing financial assurance obligations — represent costs that historical carriers may be obligated both to recover and to fund going forward.

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.
