Industrial & Manufacturing cleanup site — Restorical Research
Boeing North Field F & G Facility

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property is part of Boeing Field, where Boeing has maintained manufacturing and industrial operations since the 1930s. The facility falls within the Georgetown Steam Plant Agreed Order area, reflecting the long-standing industrial character of the surrounding corridor. Site investigations have confirmed petroleum hydrocarbon contamination in groundwater, and the property is currently under Washington's Standard Cleanup program with remediation underway. 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.

Boeing's industrial operations at this location date to the 1930s — more than five decades before 1986, when occurrence-based Commercial General Liability policies ceased covering pollution claims without exclusion. The confirmed petroleum contamination in groundwater here is consistent with decades of industrial activity predating that policy shift. With cleanup underway and remediation costs accumulating under the Standard Cleanup program, historical carriers who issued CGL policies during the facility's pre-1986 operational window may bear obligation for both past expenditures and ongoing cleanup costs.

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.
