Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1945. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Multiple landfills and waste disposal sites operated within Area D of McChord Air Force Base from the mid-1940s through the early 1970s, with at least one landfill active from 1954 to 1968. EPA Region 10 discovered volatile organic compounds, including trichloroethylene (TCE), at the American Lake Garden Tract in 1984, and the site was added to the National Priorities List that October. Remediation has included pump-and-treat systems, soil vapor extraction, in-situ amendment injections, dry well excavation, and tank removal, with some cleanup components projected to continue for up to 50 years. 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.

The contamination here traces directly to landfill and waste disposal operations that began in the mid-1940s and continued through the early 1970s — a period entirely predating 1986, when occurrence-based CGL policies still lacked effective pollution exclusions. New remedial alternatives under active consideration carry cost estimates of $1.5 million to $2.9 million, on top of the treatment systems already operating and decades of monitoring ahead. Historical carriers who issued CGL policies to operators of the Area D waste disposal sites during that pre-1986 window may remain obligated to fund a share of those ongoing and future 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.
