Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1920. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has served industrial purposes since at least the 1920s, when a raw-coal bunker and crusher occupied the site. In the 1960s the coal facilities were replaced by a 250,000-gallon concrete underground storage tank holding Bunker C oil (Fuel Oil No. 6) as backup fuel for the adjacent EnWave steam plant. Site investigations conducted between 1990 and 2022 identified petroleum contamination originating from the former UST. Under the Voluntary Cleanup Program, the selected remedy includes retaining existing engineering controls, installing new monitoring wells and a soil vapor probe, recording an environmental covenant, and five years of groundwater monitoring at an estimated cost of $130,000; a more aggressive soil-excavation alternative was evaluated at $2,900,000 but not selected. 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.

Petroleum storage and handling at this site began decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The contamination detected here traces directly to that pre-1986 bulk-fuel infrastructure — a quarter-million-gallon UST installed in the 1960s and operated continuously through the policy period. Investigation and remediation costs already incurred over three decades, together with the ongoing monitoring and characterization work still ahead, represent expenditures that historical CGL carriers may be obligated both to reimburse 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.
