Gas Station cleanup site — Restorical Research
Parkside Grocery
Leavenworth, Chelan County

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1977. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property operated as Parkside Grocery with an on-site fuel dispensing operation in Leavenworth, Chelan County, featuring a 4,000-gallon diesel underground storage tank installed around 1977 alongside two registered gasoline USTs. The diesel UST was found to have numerous pits and holes and failed a tightness test, leading to its excavation and removal along with 45 tons of contaminated soil. The site underwent a multi-year assessment process from 2003 to 2009 under the Standard Cleanup program before receiving 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.

The diesel UST at this property was installed around 1977 and leaked through progressive deterioration over years of normal operations — exactly the kind of slow, ongoing release that occurrence-based Commercial General Liability policies issued during that era were designed to cover. The documented remediation expenditures — tank removal, excavation of 45 tons of contaminated soil, backfilling, waste disposal, and years of site assessment — represent cleanup costs incurred to address contamination originating squarely within the 1977-to-1986 window when CGL policies carried no effective pollution exclusion. Historical carriers who provided coverage during that operational period 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.
