Gas Station cleanup site — Restorical Research
CENTRAL SERVICE
Enumclaw, 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.

The Clifford A Rouse Central Service property in Enumclaw operated as a vehicle service and fueling facility with underground storage tanks that were in place well before the release was reported in January 1990. Heavy oil contamination from leaking UST No. 1701 impacted both soil and groundwater at the site. Independent cleanup activities were completed to Method A Cleanup levels under the state's standard cleanup program, and the site has received a No Further Action determination from Ecology. 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 underground storage tanks at this property were installed and operational years before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. The heavy oil release from those tanks — and the full scope of remediation required to reach Method A standards — traces directly to operations conducted during that pre-1986 policy window. Historical carriers who covered Central Service during those years of tank operation may still be obligated to recover the cleanup costs the property owner incurred to close out the 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.
