Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1965. 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 gasoline station and convenience store in downtown Morton, Washington, with underground storage tanks dating to approximately 1965 — one of which was confirmed to be 29 years old at the time of a major release in 1994. In March 1994, approximately 3,200 gallons of leaded gasoline were released from a corroded UST, prompting emergency tank removal and excavation of 150 cubic yards of contaminated soil. Remediation from 1994 through 2019 included off-site hot-air vapor extraction, installation of an on-site vapor extraction system, and long-term groundwater monitoring and well maintenance. Cleanup work remains ongoing. 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 petroleum contamination at this site originated from underground storage tanks installed around 1965 and operated continuously through the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — emergency response, tank removal, soil excavation, vapor extraction, and over two decades of groundwater monitoring — trace directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies to the operators during that window may be obligated both to reimburse costs already incurred and to fund the cleanup work that remains ahead.

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.
