Industrial & Manufacturing cleanup site — Restorical Research
Stone Property Transit Site
Tacoma, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1912. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Tacoma property served as a railroad depot and trackage for the Chicago, Milwaukee, St. Paul, and Pacific Railroad from at least 1912 through 1969, with heavy metals and hydrocarbons deposited through decades of locomotive maintenance, fueling, and depot operations. Investigation has included soil sampling through test pit excavation and preparation of a cleanup action plan, which Ecology found insufficient; the site was subsequently withdrawn from the Voluntary Cleanup Program. No active remediation has yet been completed, and cleanup remains pending. 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.

CMSP railroad operations at this depot began more than seven decades before 1986 and generated the contamination that investigators have now confirmed in soil. The investigation costs already incurred — soil sampling, test pit excavation, and cleanup action plan preparation — represent documented expenditures tied directly to those pre-1986 railroad activities, and carriers who issued CGL policies to CMSP during its operating decades may be obligated to fund their recovery. With active remediation still ahead, those same historical policies remain relevant to the future cleanup expenditures that a compliant remedy will require.

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.
