Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1948. 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 retail gasoline service station since at least 1948, with underground storage tanks installed in 1948 and 1971 and two tanks replaced in 1985. Contamination was discovered during tank removals in 1998 and attributed to leaks from the older tanks, including the original 1948 installation. Lead was detected in soil samples during that investigation, consistent with decades of leaded-gasoline dispensing. The site is enrolled in the Voluntary Cleanup Program and cleanup work is ongoing; the property currently operates as a Valero-branded 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 releases at this site originated from underground storage tanks that were installed and operated for decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The contamination discovered in 1998 — including lead consistent with leaded-gasoline operations — traces directly to infrastructure in service since 1948. Historical carriers who issued CGL policies during that nearly four-decade pre-1986 operational window may be obligated both to recover remediation 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.
