Bulk Plant cleanup site — Restorical Research
BNR Occidental Street
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1940. 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 railyard with bulk petroleum storage and dispensing operations dating to the 1940s, including a 20,000-gallon aboveground fuel tank visible in 1956 aerial photography and two 1,000-gallon underground diesel storage tanks. Cleanup under the Standard Cleanup program has included the 1994 removal of both underground tanks and excavation of petroleum-contaminated soil, along with LNAPL recovery from groundwater. A 1999 Cleanup Action Plan calls for annual groundwater monitoring, institutional and engineering controls, and oxygen release compound application to treat residual contamination in soil and groundwater; that work remains ongoing. 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.

Diesel-range petroleum contamination at this site traces directly to fuel storage and dispensing infrastructure that was in place decades before 1986 — the aboveground tank alone predates 1956. Occurrence-based CGL policies issued to the operators during those pre-1986 years carried no effective pollution exclusion under Washington law and remain enforceable today. The remediation expenditures already incurred — tank removals, soil excavation, LNAPL recovery — and the ongoing costs outlined in the Cleanup Action Plan represent obligations that historical carriers may be required 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.
