Bulk Plant cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1961. 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 service yard and warehouse for Puget Sound Power & Light Company from 1961 to 2013, with fueling operations supporting the utility's fleet and equipment throughout that period. Petroleum hydrocarbon contamination was reported at the site in the mid-1990s and has been characterized as historical in nature, consistent with decades of bulk fuel storage and dispensing. Prior remediation activities have been conducted, and the site remains under active cleanup oversight through the Standard Cleanup program. 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.

Bulk fueling operations at this property began in 1961 — twenty-five years before occurrence-based Commercial General Liability policies stopped reliably covering pollution claims in 1986. The petroleum contamination documented here is the product of long-term industrial fueling activity conducted squarely within that pre-1986 policy window. Historical carriers who issued CGL policies to the site's operators during those decades may be obligated to reimburse past remediation expenditures and to fund the cleanup work that remains ahead.

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.
