Preliminary Site-Specific Analysis

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

King County Fire District 25 is a government-agency property in Renton where petroleum-contaminated soil was discovered at the base of a former excavation. The site previously carried a "Reported Cleaned Up" designation, indicating earlier remediation activity; cleanup work has nonetheless resumed under Washington's Standard Cleanup program. Grant funding of $200,000 to $300,000 is available to assist the local government with independent remedial actions at the site. 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.

Government fire districts routinely maintain on-site fuel storage for their vehicle and equipment fleets, and the petroleum contamination documented here is consistent with fuel-storage operations that, at facilities of this age, predate the 1986 shift away from occurrence-based Commercial General Liability coverage. The site's trajectory — an initial cleanup, a "Reported Cleaned Up" designation, and a subsequent return to active remediation — reflects the kind of multi-phase cost pattern that historical CGL carriers may still be obligated to address. Where pre-1986 policies were issued to operators of this facility, those carriers may retain exposure for the ongoing remediation 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.
