Gas Station cleanup site — Restorical Research

Bellevue, King County
Restorical Research
Preliminary Site-Specific Analysis

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

This property has operated as a Chevron service station in Bellevue, with six underground storage tanks totaling 36,500 gallons of gasoline, diesel, waste oil, and hydraulic oil capacity removed in 1989 along with two hydraulic hoists. Cleanup involved overexcavation of contaminated soil — 68 cubic yards hauled offsite for treatment — recovery of solvent-contaminated sump fluids, installation of a Stage II vapor recovery system in 1994, and multi-year monitoring and investigation spanning 1989 through at least 2009. New replacement tanks were installed and the site continues to operate as an active service station with a food mart. 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 and solvent contamination at this property originated from underground storage tanks and service-bay operations that were in place well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank removals, soil excavation and offsite treatment, vapor recovery, and two decades of monitoring — represent costs tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during that operational window may be obligated both to recover costs already incurred and to fund the ongoing cleanup work at this site.

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.
