Gas Station cleanup site — Restorical Research
Plaid Pantry 309
Seattle, 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.

Plaid Pantry Store #309 operated as a convenience store and gas station at 720 Taylor Avenue North in Seattle, with underground storage tanks used to dispense petroleum products. The USTs leaked, releasing petroleum hydrocarbons into soil and groundwater — contamination serious enough to be tracked in Ecology's Leaking Underground Storage Tank database. A Site Check was conducted in 1998 and the property entered the Voluntary Cleanup Program; Ecology issued a No Further Action determination in February 2001. 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 Plaid Pantry chain was founded in 1961 and built its Pacific Northwest convenience store and gas station network well before 1986, when occurrence-based Commercial General Liability policies were the industry standard. The underground storage tanks at Store #309 — whose late-1990s leak discovery and typical tank lifecycle suggest installation during that pre-1986 window — caused the petroleum contamination that required investigation and remediation under the Voluntary Cleanup Program. Historical CGL carriers who covered the facility's operations during that era may bear obligation for the cleanup costs incurred at this site.

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.
