Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Boeing Plant 2, located at 7755 E Marginal Way S in Seattle, operated as a Boeing Commercial Airplane Group manufacturing facility. The site is contaminated by hazardous substances and dangerous wastes requiring RCRA Corrective Action for soils and groundwater. Cleanup activities include ongoing oversight of corrective actions — with an annual oversight cost limit of $80,000 — and extensive habitat restoration involving structure removal, sediment corrective measures, shoreline stabilization, and replanting of thousands of plants. 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.

Contamination at this facility stems from industrial manufacturing operations that predate 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The site's documented remediation obligations — RCRA corrective actions for hazardous substances in soil and groundwater, plus large-scale habitat restoration — represent substantial ongoing costs tied to releases that originated during the pre-1986 policy window. Historical carriers who insured Boeing's operations during that period may be obligated both to recover past cleanup expenditures and to fund the corrective actions still under way.

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.
