Bulk Plant cleanup site — Restorical Research
US Oil Pipeline 100th and A
Tacoma, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

The McChord Pipeline, operated by U.S. Oil & Refining Co., delivers jet fuel from USOR's Tacoma refinery to Joint Base Lewis-McChord. In August 2017, a third-party contractor punctured the pipeline, triggering an initial investigation that confirmed benzene, non-halogenated solvents, and petroleum hydrocarbons in groundwater at the site. The site entered the Voluntary Cleanup Program in 2018, and a remedial investigation and feasibility study was completed by July 2020 following multiple groundwater sampling events. The site has since received 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.

U.S. Oil & Refining Co. has operated its Tacoma refinery since the 1950s and used the McChord Pipeline to deliver jet fuel to what is now Joint Base Lewis-McChord — a military installation active since 1938. CGL policies in force while USOR ran that refinery-to-base fuel corridor would have insured the pipeline's petroleum-transfer operations without an effective pollution exclusion, covering exactly the type of groundwater contamination — benzene and petroleum hydrocarbons — confirmed at this location. The documented remediation costs, from initial response through the investigation and cleanup work that secured a No Further Action determination, are expenditures those historical carriers may 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.
