Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1973. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as a steel production and rolling facility operated successively by Northwest Steel Rolling Mills, Salmon Bay Steel, and Birmingham Steel, with the primary warehouse erected in 1973 and contamination attributed to fill material placed on the property prior to that date as well as former industrial operations. Cleanup under the Standard Cleanup program included excavation and stabilization of over 14,100 cubic yards of impacted soil, with the long-term remedy relying on containment beneath the existing building and asphalt cover, institutional controls through a restrictive covenant recorded in 1999, and ongoing five-year periodic reviews and site inspections. The property was vacant at the time cleanup was finalized in the late 1990s. 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 site originated from industrial fill and steel manufacturing operations that predate 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The scale of documented remediation — more than 14,000 cubic yards of soil excavated and stabilized, plus long-term containment and monitoring obligations that continue through periodic reviews — represents substantial expenditures tied directly to those pre-1986 operations. Historical carriers who insured the facility's operators during that window may be obligated to recover past cleanup costs and to fund the ongoing containment and monitoring requirements.

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.
