Industrial & Manufacturing cleanup site — Restorical Research
Silicon Metaltech Lagoon
199 4th St, Rock Island, Douglas County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1974. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

Silicon Metaltech is an active silicon smelting plant that operates electric arc furnaces producing ferrosilicon at this Rock Island facility, generating approximately 40 tons of metal fume waste every 16 hours. The facility maintains eight on-site fume waste lagoons — three active and five inactive — where water slurry from the furnaces is pumped for settling in series. Cleanup activities to date include removal of an underground storage tank and plastic lining of one inactive lagoon for containment; site assessment and monitoring have been ongoing since at least 1978, and the Department of Ecology formally initiated a cleanup project in 2014. 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.

Metal fume waste deposition at this facility began no later than 1974 — more than a decade before 1986, when occurrence-based CGL policies still lacked effective pollution exclusions in Washington. The contamination here is the direct product of continuous heavy industrial operations spanning the pre-1986 window, not a discrete accident, making it precisely the type of slow, ongoing release those policies were written to cover. With five inactive lagoons on site and a formal cleanup project underway since 2014, the remediation costs — past and future — represent expenditures that historical carriers whose policies were in force during those decades of operation may be obligated to fund.

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.

What We Look For

  • Historical insurance policies (pre-1986)

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.
