Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as Chevron Service Station 94998, a retail fuel outlet with underground storage tanks and dispenser islands at 1501 Auburn Way N in Auburn. Cleanup activities under the Voluntary Cleanup Program have included a 1999 excavation of former USTs and contaminated soil, followed by extensive groundwater monitoring and sampling from 2010 through 2014 addressing petroleum hydrocarbons and light non-aqueous phase liquid (LNAPL) in the subsurface. The station is no longer in operation, and remediation efforts — part of Chevron's broader multi-site independent remedial action program — remain 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.

Petroleum contamination at this site originated from underground storage tanks estimated to have been installed in the mid-1970s, well before 1986 when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. More than two decades of documented remediation expenditures — tank and soil excavation, long-term groundwater monitoring, LNAPL management, and continued VCP enrollment — trace directly to releases from those pre-1986 fueling operations. Historical carriers who issued CGL policies during the station's early operational years 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.
