Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This site at Snoqualmie Pass appears to have been a historic railroad facility used for bulk storage and dispensing of heavy fuel oil for locomotives. Free-phase heavy oil was discovered in soil and floating on groundwater during a test pit excavation and subsequent investigation in 2008 and 2009. Further remedial action is required, and the site has been directed toward cleanup under Washington's Standard Cleanup program, with the Voluntary Cleanup Program identified as a potential pathway for addressing the contamination. 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.

Free-phase heavy oil floating on groundwater is the signature of a long-standing release, not a recent spill — the contamination found here almost certainly originated from fueling and storage operations conducted decades before its 2008 discovery. The full scope of remediation needed to address free-phase product in both soil and groundwater has yet to be determined, meaning the largest cleanup expenditures still lie ahead. Historical carriers who issued CGL policies to operators of this facility during the pre-1986 period may be obligated to fund those 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.
