Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property encompasses bulk fuel storage and aircraft washrack operations at McChord Air Force Base across three contaminated areas — Sites SS-34, WP-44, and DP-60 — with petroleum hydrocarbons (TPH, BTEX, gasoline, diesel, and heavy oil) and lead identified as primary contaminants. Remediation to date has included excavation and recycling of 427 tons of TPH-contaminated soil at Site WP-44 in 2000, along with purge water collection and discharge to an on-site oil-water separator. The site remains under active long-term groundwater monitoring and intrinsic bioremediation across all three areas, with Site SS-34 continuing to operate as an active bulk fuel storage facility. 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 installation originated from bulk fuel storage and aircraft servicing operations that were documented as far back as 1982 and monitored as early as 1983 — well within the era when occurrence-based CGL policies carried no effective pollution exclusion. The excavation, soil disposal, and purge-water treatment costs already incurred represent past expenditures that historical carriers may be obligated to recover. With long-term groundwater monitoring and natural attenuation continuing across Sites SS-34, WP-44, and DP-60, the O&M obligations here are ongoing — and pre-1986 policies may be available not only to recoup past remediation costs but to fund that continuing monitoring work as well.

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.
