Public Works cleanup site — Restorical Research
Mount Vernon City Hall Alley
Mount Vernon, Skagit County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1964. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as the City of Mount Vernon's municipal vehicle fueling point from 1964 through 1997, with a 550-gallon diesel and a 1,000-gallon gasoline underground storage tank supplying city fleet operations at City Hall. Both USTs were removed in 2000, along with the excavation and thermal desorption treatment of approximately 621 tons of petroleum-contaminated soil. Quarterly groundwater monitoring across five wells ran from January 2001 through February 2003, and in 2007 Ecology determined that further remedial action was necessary to address residual TPH gasoline and benzene in groundwater. 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.

Petroleum contamination at this site originated from underground storage tanks installed in 1964 and operated continuously for over three decades — more than twenty years before occurrence-based CGL policies gave way to claims-made forms with absolute pollution exclusions. The documented remediation costs already incurred — tank removal, large-scale soil excavation and treatment, years of groundwater monitoring — along with the additional cleanup Ecology has required for residual groundwater contamination, represent expenditures that historical carriers who covered the city's operations during the pre-1986 window may be obligated both to reimburse and to fund going forward.

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.
