Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1971. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

This property has operated as a gasoline station and car wash at 209 Central Ave S in Kent since at least 1971, with underground storage tanks installed as early as 1972 dispensing gasoline as the sole petroleum product stored on site. Cleanup under the Voluntary Cleanup Program ran from 1992 through 2019 and included excavation of 250 cubic yards of contaminated soil, groundwater pump-and-treat operations recovering 100,000 gallons, soil vapor extraction, in-situ injection of over 2,500 pounds of chemical oxidation compounds, and years of groundwater monitoring and confirmation sampling. The site has received a No Further Action determination. 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 property traces directly to underground storage tanks installed in 1972 and operated continuously through the era when occurrence-based CGL policies were standard — meaning the specific carriers who insured this gasoline station during the 1970s and early 1980s likely covered the very operations that caused the release. Twenty-seven years of documented remediation expenditures — soil excavation, groundwater recovery, chemical oxidation, vapor extraction, and long-term monitoring — represent costs that those identified policy periods may be obligated to reimburse. The 1992 soil sampling that detected lead consistent with pre-1986 leaded gasoline further anchors the contamination timeline to the coverage window.

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.

What We Look For

  • Historical insurance policies (pre-1986)

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.
