Gas Station cleanup site — Restorical Research
Black Lake Grocery
Olympia, Thurston County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1946. 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 grocery store and gasoline station since prior to 1946, with underground storage tanks dispensing gasoline and heating oil to the public for decades. Multiple USTs were removed in 1992 and 1995, with 1,200 cubic yards of petroleum-contaminated soil excavated and bioremediated. Remediation also included installation of a groundwater treatment wall, and the site now carries an estimated 25- to 50-year performance and groundwater monitoring obligation at a projected cost of $210,584. A new UST system with two tanks and three fuel dispensers was installed in 1995, and the property continues to operate as a retail grocery store and gasoline station. 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 that were in service for decades before 1986 — with documented operations reaching back prior to 1946. Occurrence-based Commercial General Liability policies issued to the operators during that pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable today. The remediation costs already incurred and the decades of monitoring still ahead represent expenditures that historical carriers who covered this property during its long operational history 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.
