Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1937. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property has hosted commercial fuel operations since at least 1937, when Louie's Fuel Co. occupied a building on the western portion of the site. By 1967, all structures were replaced with a carwash and fueling station, and two 6,000-gallon underground storage tanks storing gasoline were installed, with an additional tank added in 1971. A subsurface investigation confirmed benzene and gasoline-range petroleum hydrocarbons in perched groundwater at concentrations exceeding MTCA Method A cleanup levels, with petroleum-related contamination also detected in air. The site has received a No Further Action determination under Washington's Standard Cleanup program. 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 storage and dispensing operations at this property date to at least 1967, with commercial fuel use stretching back to 1937 — decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions in 1986. The benzene and petroleum contamination documented in groundwater and air traces directly to those pre-1986 underground storage tank operations. Remediation expenditures incurred to bring this site to its No Further Action status represent costs that historical carriers who issued occurrence-based CGL policies during the 1937–1986 operational window may still be obligated to cover.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
