Gas Station cleanup site — Restorical Research
Old Gas Station Mineral WA
Mineral, Lewis 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 those prior operations and through 1986 could fund a cleanup.

This parcel in Mineral, Lewis County was home to three successive gasoline stations whose underground storage tanks remained buried on-site until their discovery in 1990. A Phase II site assessment identified petroleum hydrocarbon and BTEX contamination in subsurface soil traced to those old USTs; the report characterizes the assessment as scoring and contamination identification, with no remediation activities conducted to date. The site remains in the Awaiting Cleanup phase under Washington Ecology's Standard 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 underground storage tanks at this property were already described as "old" when they were discovered in 1990, indicating that the releases they caused occurred well before 1986 — the year occurrence-based Commercial General Liability policies began carrying effective pollution exclusions. Three separate gasoline station operations over the life of this parcel each represent a potential CGL policy window from that pre-1986 era. The property owner now faces the full cost of investigation and cleanup with no prior remediation to offset it, and historical carriers whose policies covered any of those operators may still be obligated to fund those costs.

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.
