Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1895. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as a locomotive maintenance and fueling facility for BNSF (and its predecessor BNRR) dating to the late 1890s, storing Bunker C oil in below-grade wooden, concrete, and steel sumps and aboveground steel tanks, and diesel fuel in both aboveground and underground storage tanks until BNRR discontinued fuel handling at Skykomish in 1974. Light non-aqueous phase liquid (LNAPL) petroleum contamination is attributed to releases during those historic fueling operations, with oil seeps documented on the property as early as 1912. Cleanup work to date has included excavation and removal of petroleum source materials and underground storage tanks, removal of 100 tons of lead-contaminated sandblasting grit, and an interim remedial action for product recovery initiated in late 1995. Active remediation continues under a multi-year Agreed Order for remedial investigation and feasibility study, with ongoing waste management for investigation-derived soils and purge water. 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 releases at this site trace directly to bulk fuel storage and locomotive fueling operations that ran from the late 1890s through 1974 — decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. Oil seeps were documented on the property as early as 1912 and underground storage tanks were in place by at least 1967, meaning contamination-triggering releases occurred across the full span of the pre-1986 policy window. The documented remediation costs — UST removals, soil and source excavation, lead-grit disposal, product recovery, and an ongoing RI/FS — represent expenditures that historical carriers whose policies were in force during the fueling era 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.
