Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1965. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

Silicon Metaltech has operated as an active silicon smelting plant in Rock Island since at least the mid-1960s, with mercury used in its onsite quality control laboratory through the late 1960s. In 1988 and 1989, the former laboratory building was razed and approximately 142 cubic yards of mercury-contaminated soil were excavated and placed in temporary storage crates. Contaminated soil remained at the site following those initial excavation efforts, and additional remediation was still being planned as recently as 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.

Mercury was in active use at Silicon Metaltech's quality control laboratory from the mid-1960s through the late 1960s — more than fifteen years before 1986, when occurrence-based CGL policies were still the industry standard and lacked effective pollution exclusions. Carriers who issued policies to Silicon Metaltech during those mercury-use years may be obligated to fund both the 1988–1989 excavation costs and the unresolved remediation that remains. For an active industrial operation carrying an open cleanup obligation tied to decades-old laboratory operations, identifying those historical policy assets is a material financial consideration.

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.
