Gas Station cleanup site — Restorical Research
BP 11062
Seattle, King County

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1966. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a BP and ConocoPhillips 76-branded retail fuel station from at least the mid-1960s through 2009, with an underground storage tank complex comprising three gasoline tanks totaling 34,000 gallons of capacity — the tanks implied to have been installed around 1966. Cleanup activities included full UST removal, excavation of approximately 50 cubic yards of impacted soil, vacuum-based recovery of 4,162 gallons of petroleum-affected groundwater, and installation of Soil Vapor Extraction piping. Groundwater monitoring ran from 1991 through 2018, and natural attenuation remains the active remediation technique at the site today. 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 gasoline tanks here were installed around 1966 and dispensed leaded fuel — a marker that definitively anchors contamination-generating operations to the pre-1986 era. The documented cleanup expenditures tied to those operations — UST and soil removal, vacuum groundwater recovery, SVE infrastructure, and a 28-year monitoring program — represent past costs that historical CGL carriers may be obligated to recover. Because natural attenuation is still the active remediation method and monitoring obligations continue, those same pre-1986 policies may also be called upon to fund the site's ongoing cleanup commitments.

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.
