Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1914. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup.

Tacoma Rail has operated this railyard since 1914, with historical operations that included the use of creosote-treated wooden crossties. Recent incidents in 2020 and 2021 resulted in documented contamination, with benzene, MTBE, and petroleum hydrocarbons identified at the property. Groundwater was encountered at 30 inches below ground surface during remediation but was never sampled, and suspected groundwater contamination remains uncharacterized. The site is currently awaiting cleanup under the Standard Cleanup program. 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.

This railyard has been in continuous industrial operation since 1914 — more than seven decades of activity before 1986, during which occurrence-based CGL policies carried no effective pollution exclusion in Washington. While documented contamination at the site has been attributed to recent incidents, suspected groundwater contamination beneath a century-old railyard that used creosote-treated crossties has never been sampled or fully investigated. As the site's full environmental condition is assessed and cleanup costs are incurred, pre-1986 carriers who insured those decades of railyard operations may bear obligations tied to any historical releases that investigation reveals.

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.
