Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1943. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Industrial use at this property began in 1943 with the construction of a Shell heating oil distribution facility on the site's northwestern corner. Sunset Coal and Oil subsequently operated the petroleum distribution facility from 1950 through 1967, during which period petroleum hydrocarbons — including gasoline-range, diesel-range, and oil-range TPH — were released into soil and groundwater. Cleanup under the Voluntary Cleanup Program has included general remediation of contaminated soil and groundwater, a five-year program of semi-annual groundwater monitoring, and the implementation of restrictive covenants to manage residual contamination and support ongoing remedy maintenance. 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 distribution operations at this site began in 1943 — more than four decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and lacked effective pollution exclusions in Washington. The TPH-G, TPH-D, and TPH-O contamination documented in soil and groundwater here is directly traceable to bulk-plant operations conducted throughout that pre-1986 window. The documented remediation costs, the years of groundwater monitoring, and the perpetual obligations created by the restrictive covenants are all expenditures tied to releases that historical carriers 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.
