Gas Station cleanup site — Restorical Research
Montesano Fire Dept
Montesano, Grays Harbor 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 — and recover costs already spent.

This property at 310 East Pioneer Street operated as a Mobile service station before being demolished around 1975, with its underground storage tanks removed approximately four years later. The Montesano Fire Department subsequently occupied the site and installed its own fuel tanks in 1978. Cleanup activities in 1995 included removing two 285-gallon underground storage tanks, associated pumps and piping, and excavating contaminated soils to a depth of 19 feet; recovered fuel was reprocessed and excavated soils were stockpiled for bioremediation. As of 2013 the site remains on Ecology's list for further testing and possible cleanup. 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 property traces to two distinct pre-1986 operations — a Mobile service station that dispensed fuel to the public for years before its 1975 demolition, and fire-department tanks installed in 1978 — meaning any CGL policies in force for either operator during those specific windows would have been occurrence-based forms with no effective pollution exclusion. The remediation costs already incurred here, from deep soil excavation to tank removal to ongoing bioremediation, plus whatever further cleanup Ecology requires, represent expenditures those historical carriers may be obligated both to reimburse and to fund going forward.

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.
