Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1956. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup.

This property operated as a gasoline station from 1956 to 1975, after which it transitioned to automotive repair use — a function it continues to the present day. A site investigation completed in 2018 confirmed the presence of petroleum and solvent-related compounds in soil vapor, attributed to historical releases from both the gasoline station and the subsequent automotive repair operations. The site is currently in the initial investigation stage and awaiting cleanup; no remediation work has commenced. 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.

Fuel dispensing and automotive service operations at this address began in 1956 — three decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and contained no effective pollution exclusion in Washington. The contamination now documented in soil vapor is attributed to historical releases tied directly to those pre-1986 operations. The investigation and remediation costs the current property owner faces could plausibly be recovered from historical carriers whose policies were in force during the years the contamination originated.

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.
