Public Works cleanup site — Restorical Research
Ryder Student Transportation Services
Seattle, King County
Restorical Research
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.

This Seattle Public Utilities property operated as Ryder Student Transportation Services, a student transportation fleet facility with underground storage tanks used for vehicle fueling. Leaking underground storage tanks were identified at the site, which has been on Ecology's Confirmed and Suspected Contaminated Sites List since 1997. Cleanup is underway through the Voluntary Cleanup Program, with both an Interim Action and an Independent Cleanup Action currently in progress. 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 leaking underground storage tanks at this fleet fueling facility represent the kind of gradual petroleum release that typically began years or decades before discovery — and this site's contamination was already confirmed by 1997. If fueling operations at the Ryder facility were underway before 1986, occurrence-based CGL policies covering that period may apply to the ongoing remediation costs now being incurred under the Voluntary Cleanup Program's Interim Action and Independent Cleanup Action.

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.
