Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1909. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This site was developed as a rail yard in the early 1900s, with tracks extended to Auburn in 1909 and the Auburn Railyard opening in 1915 as the western freight terminal for the Northern Pacific Railroad. Facilities included a roundhouse, fueling stations, engine wash facilities, and wastewater disposal ponds, with underground storage tanks holding several hundred thousand gallons of bunker fuel, diesel, gasoline, and cleaning solvents. USTs were removed in the late 1980s, and investigations beginning in 1986 revealed a groundwater plume containing TPH-D, TPH-O, benzene, PCE, TCE, and LNAPL free product at thicknesses up to 5.6 feet — all exceeding MTCA Method A cleanup levels. 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.

Railroad operations at this property date to 1909 — more than seven decades before the 1986 shift away from occurrence-based Commercial General Liability policies. The contamination identified here — petroleum hydrocarbons, chlorinated solvents, and free product in groundwater within Auburn's wellhead protection zone — traces directly to fueling, maintenance, and solvent-handling activities conducted under those pre-1986 policies. The cleanup costs this site now faces could plausibly be funded by historical carriers whose occurrence-based CGL policies were in effect during the decades of active railyard operations.

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.
