Gas Station cleanup site — Restorical Research
Northwest Investments
Vancouver, Clark County

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

Northwest Investments is a Chevron brand service station at 610 NE 99th Street in Vancouver, featuring a convenience store, a six-dispenser fueling canopy, a car wash, and three underground storage tanks for diesel, unleaded, and super unleaded gasoline. The soil and groundwater contamination at the site is attributed entirely to an adjacent former fuel facility, Astro Station at 716 NE 99th Avenue, whose environmental investigation report dates to March 1991 and whose petroleum release was initially reported in June 1991. The contamination — TPH-GRO, BTEX, and related petroleum hydrocarbons — is characterized as significantly weathered, predating Northwest Investments' 1995 operations. The site enrolled in the Voluntary Cleanup Program in 2015, adopted natural attenuation with quarterly groundwater monitoring as the cleanup action, and has reached No Further Action status. 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.

The weathered petroleum plume migrating from Astro Station — first documented in an environmental investigation as early as March 1991 — is consistent with a release originating from pre-1986 fuel-dispensing operations, though the record characterizes this as a strong inference rather than a confirmed date. Northwest Investments' decade-long VCP enrollment produced a documented and quantifiable remediation record: installation of three monitoring wells, quarterly groundwater sampling, purge-water disposal, and well redevelopment. With the site now at No Further Action, that full scope of expenditures is known — a defined cleanup cost record that historical carriers who insured Astro Station's operations before 1986 may be obligated to recover.

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.
