Gas Station cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1912. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This Puyallup property and its west-adjoining parcel carry a documented industrial history dating to at least 1912, when auto repair operations began at the adjacent site, with fuel and oil dispensing added by 1927. The adjacent automobile service station operated with underground storage tanks from 1951 through 1989, at which point three USTs totaling 14,000 gallons and an in-ground hoist were removed; a separate 350-gallon heating oil UST was also removed from the subject property. General remediation on the adjacent parcel was completed in 1990, and multi-year monitoring there produced a No Further Action determination in 2012, while investigation of the subject property — where vinyl chloride, TCE, and PCE contamination has been attributed to the former service station and parts-cleaning solvents — remains ongoing under the Voluntary Cleanup Program. 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 chlorinated-solvent contamination at this site — vinyl chloride, trichloroethylene, and tetrachloroethylene — traces to auto service and parts-cleaning operations that ran for several decades before 1986, when occurrence-based CGL policies still lacked effective pollution exclusions. Carriers who issued policies to operators of the adjacent service station during its 1951–1989 run may carry liability for the contamination that has since migrated onto this parcel. The documented cost trail — UST removals, soil remediation, years of groundwater monitoring, and an open Voluntary Cleanup Program investigation — represents expenditures tied directly to those pre-1986 operations that historical insurers may be obligated to fund.

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.
