Industrial & Manufacturing cleanup site — Restorical Research

New Holstein, Calumet County

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1956. 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 served as a small engine manufacturing facility from 1956 through 2006, with polychlorinated biphenyl (PCB) contamination attributable to decades of industrial operations — PCBs were banned by the EPA in 1979, confirming the contamination's pre-1986 origin. PCB-contaminated sediment has been documented across approximately 8.5 miles of downstream waterways, and remediation efforts between 2001 and 2020 removed over 140,000 tons of contaminated sediment and soil across multiple operable units. Fish consumption advisory signs have been posted along affected reaches, and the site remains an active Wisconsin DNR Environmental Remediation Program case with long-term surface water and sediment oversight continuing. 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 facility began in 1956 and continued for three decades before 1986, during the period when PCB contamination originated and migrated through downstream waterways. The ongoing surface water and sediment evaluation, natural recovery assessment, and any additional remediation required across multiple operable units 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.
