Preliminary Site-Specific Analysis

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

This property operated as a United Parcel Service vehicle fueling facility in Tacoma, with underground storage tanks storing gasoline and diesel for fleet operations. Petroleum contamination — including benzene and gasoline — was identified in groundwater beneath the site. Remediation under the Standard Cleanup program successfully brought groundwater concentrations below applicable cleanup levels, and Ecology issued a No Further Action determination in December 2024. 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.

UPS has maintained operations in the Tacoma and Pierce County area since the early 1900s, and the petroleum contamination at this facility — benzene and gasoline from underground storage tanks — is consistent with decades of vehicle fueling operations predating 1986. Occurrence-based Commercial General Liability policies issued during that pre-1986 operational window carried no effective pollution exclusion in Washington and remain enforceable today. The remediation expenditures required to bring this site's groundwater to below cleanup levels represent costs that historical carriers who wrote those policies may still be obligated to cover.

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.
