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.
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.
