Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1870. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as the Interbay Railyard since the 1870s, serving as Burlington Northern Railroad's maintenance, repair, and fueling hub for locomotives and railcars. The facility's industrial infrastructure includes a 2.4-million-gallon aboveground diesel storage tank, multiple underground storage tanks for diesel, gasoline, and lube oil, a roundhouse, machine shop, car repair shop, and locomotive wash rack. Cleanup efforts have included excavation and removal of multiple underground storage tanks and contaminated soil, LNAPL recovery operations that removed 1,776 gallons of free product between 1993 and 2010, and an on-site wastewater treatment plant processing up to 136,000 gallons of contaminated water daily. Remediation is ongoing. 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.

Contamination at this railyard stems from more than a century of industrial fueling, maintenance, and solvent use — operations that were well established decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. The documented remediation expenditures here — tank removals, soil excavation, long-term free-product recovery, daily wastewater treatment — represent costs tied directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies during the railyard's long operational window may be obligated both to recover past cleanup costs and to fund the remediation work that continues today.

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.
