Gas Station cleanup site — Restorical Research
Gull 0263
Seatac, King County
Restorical Research
Preliminary Site-Specific Analysis

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

This property operated as Gull Service Station No. 263, a gasoline station in SeaTac, before being redeveloped as a Taco Bell. A release of gasoline and BTEX compounds — benzene, ethylbenzene, toluene, and xylenes — contaminated soil and groundwater at the site. Independent remedial actions were carried out under the Voluntary Cleanup Program, with investigation and remediation work documented in reports from 1992 through 1993. Ecology issued a No Further Action determination in 1999. 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 gasoline and BTEX contamination at this property originated from underground storage tank operations at the former Gull station — the type of slow, cumulative release that occurrence-based Commercial General Liability policies were written to cover. The site's listing in the Leaking Underground Storage Tank database and seven years of investigation, remediation, and regulatory oversight represent documented cleanup expenditures tied to those historical fueling operations. CGL carriers who insured the station during its pre-1986 operating years may still be obligated to recover those 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.
