Public Works cleanup site — Restorical Research
Tacoma Port Train Spill
update, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

The Port of Tacoma's South Intermodal Transfer Yard has served as a rail hub for multiple railroad operators, including Burlington Northern, Southern Pacific, and Tacoma Rail, with the Port itself established in 1918. In June 2017, a train engine oil spill was reported on Tracks 5 and 6, releasing diesel petroleum into the yard. An initial investigation confirmed groundwater is suspected to be contaminated with diesel petroleum and other substances above MTCA cleanup levels, with the release located within a ten-year travel time of a community wellhead protection zone and approximately 940 feet from the Puyallup River. The site is enrolled in the Standard Cleanup program and remediation is underway. 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 Port of Tacoma has operated this intermodal rail yard since the early twentieth century, with railroad tenants whose operations at this location trace back decades before 1986 — Tacoma Rail since 1914, Burlington Northern's predecessor lines since the 1800s, and Southern Pacific since 1865. Occurrence-based Commercial General Liability policies issued to the Port and its rail operators during that pre-1986 window likely carried no effective pollution exclusion under Washington law. The cleanup expenditures now being incurred at this yard — site investigation, groundwater assessment, and remediation in a sensitive wellhead-protection area near the Puyallup River — represent costs those historical carriers may be obligated to fund.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

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 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
