Gas Station cleanup site — Restorical Research
Arco 4311
300 NE 78th St, Vancouver, Clark County
Restorical Research
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 recover the cleanup costs already paid.

This property operated as a gasoline service station under Arco and its predecessors from at least 1965, with nine underground storage tanks storing gasoline across decades of retail fuel operations. Cleanup under the Voluntary Cleanup Program included removal of five USTs in 1991 and four additional 10,000-gallon fiberglass USTs in 1999, quarterly groundwater monitoring from 1993 through 2013, and Oxygen Releasing Compound injection in 2010 to address benzene and total petroleum hydrocarbons exceeding MTCA Method A Cleanup Levels — with floating petroleum product detected in at least one monitoring well. The Department of Ecology issued a No Further Action determination in December 2013. 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 installed and operated more than two decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The documented remediation expenditures — nine UST removals across two phases, twenty years of quarterly groundwater monitoring, and in-situ chemical treatment — were incurred to address releases tied directly to those pre-1986 fuel operations. Historical carriers who issued CGL policies during Arco's operational window beginning in 1965 may still be obligated to recover those cleanup costs.

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.
