Public Works cleanup site — Restorical Research
National Marine Fisheries Science Center

Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1966. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as the NOAA National Marine Fisheries Northwest Center, a federal government facility with underground storage tanks installed as early as 1966 and 1977. Cleanup activities have included the excavation and removal of four underground storage tanks and associated product lines, overexcavation of approximately 5.10 tons of petroleum-contaminated soil treated by thermal desorption, and a groundwater product recovery program with discharge through an oil/water separator. Continued groundwater monitoring for one year was recommended following the remediation work. 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 tanks at this federal facility were installed in 1966 and 1977 — squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Soil sampling from the gasoline tank excavation included analysis for Total Lead, indicating the likely historical use of leaded gasoline and reinforcing that contamination originated well before 1986. The documented remediation expenditures — tank removals, soil excavation and thermal treatment, groundwater recovery — represent costs that historical carriers who provided CGL coverage during those operational years 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.
