Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1968. Historical insurance policies issued during operations at this property and through 1986 could help fund the multi-phase investigation and remediation work ahead under Wisconsin DNR oversight.

This property has been in continuous industrial use since the late 1960s, with manufacturing operations that included parts degreasing with chlorinated solvents — a use confirmed by a prior Wisconsin DNR Environmental Remediation Program case documenting solvent contamination near a former underground storage tank. Contaminated fill material containing chlorinated volatile organic compounds, polycyclic aromatic hydrocarbons (PAHs), and metals was placed on-site during facility expansion between 1980 and 1990. Grab groundwater samples from multiple borings have confirmed trichloroethylene (TCE) and vinyl chloride at concentrations exceeding Wisconsin NR 140 enforcement standards, and the Wisconsin DNR did not approve the initial Site Investigation Report, directing further investigation and remediation work. That history could support an insurance coverage claim against the carriers who issued policies more than 40 years ago — coverage that could help fund the cleanup ahead.

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 Wisconsin — and those policies may provide coverage that remains enforceable today. 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.

Industrial operations at this property began in the late 1960s, with chlorinated solvent use in manufacturing processes and placement of contaminated fill material confirmed during the period before 1986. The additional site investigation required by the Wisconsin DNR, along with the groundwater remediation and long-term monitoring needed to address TCE and vinyl chloride contamination exceeding NR 140 enforcement standards, represent substantial future costs that carriers insuring the businesses that operated here before 1986 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.

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 viable insurance coverage exists to fund the cleanup, 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.
