Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

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

This property has a long history of industrial operations predating 1986, with an EPA Superfund Site Assessment recorded as early as June 1980 and a Wisconsin DNR notification of hazardous substance discharge filed in July 1985 describing the contamination as historic. Volatile organic compounds, petroleum hydrocarbons, engine waste oil, lead, and chlorinated solvents — including trichloroethylene (TCE) and 1,4-dioxane — have been confirmed in soil and groundwater, with TCE exceeding NR 140 Enforcement Standards at multiple monitoring wells. The chlorinated volatile organic compound plume continues to expand and may be migrating off-site, with enforcement standard exceedances documented on an adjacent property to the south and residual soil contamination in the public right-of-way. 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 site were well established before 1986, with federal and state environmental actions beginning as early as 1980 and contamination officially characterized as historic by the time of the 1985 DNR notification. The ongoing groundwater investigation, off-site plume delineation, and remediation work required under Wisconsin DNR Environmental Remediation Program oversight represent future costs that those historical carriers 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.
