Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1914. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a petroleum bulk storage and distribution terminal since at least 1914. Standard Oil — later Chevron — ran bulk storage operations at the site from approximately 1918 through 1980, handling gasoline, diesel fuel, and stove oil from a tank farm with a load rack; in 1980, the facility was divested to Associated Petroleum for continued bulk terminal use. Cleanup activities have included underground tank removal, trenching and excavation, pump island retrofitting, and installation of a drainage system. Active groundwater treatment via granular activated carbon is ongoing during multi-year monitoring events. 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 contamination at this site originated from bulk storage and distribution operations that ran for decades before 1986, the era when occurrence-based CGL policies had no effective pollution exclusion. Documented remediation costs already incurred — tank removals, excavation, and initial groundwater treatment — represent past expenditures for which historical carriers who issued policies to Standard Oil, Chevron, and their successors during the pre-1986 operating window may be obligated to reimburse. Those same carriers may also bear responsibility for the active granular activated carbon treatment and ongoing multi-year monitoring the site still requires.

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.
