Industrial & Manufacturing cleanup site — Restorical Research
Wausau Manufacturing Group - Future DPW Site
Wausau, Marathon County

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1907. 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 heavy industrial facility from 1907 through 1983, with iron works and metal fabrication operations — including steel bridge and snowplow manufacturing — spanning more than six decades, followed by material handling equipment manufacturing from 1971 to 1983. Metals, polycyclic aromatic hydrocarbons (PAHs), and volatile organic compounds (VOCs) have been confirmed in soil, and groundwater monitoring has revealed arsenic and lead above Wisconsin NR 140 preventive action limits, with chloride concentrations exceeding enforcement standards at more than 2,600 mg/L. A previous Environmental Remediation Program case documented hazardous lead-based paint waste from late-1970s operations, and Wisconsin DNR denied site closure in February 2025, directing additional 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 — including iron works, metal fabrication, and material handling equipment manufacturing — began in 1907 and continued through 1983, spanning more than seven decades of heavy industrial activity before 1986 during which metals, PAHs, and VOCs were introduced into soil and groundwater. With the Wisconsin DNR denying site closure in February 2025 and directing additional investigation and remediation to address contaminants including arsenic and lead above NR 140 preventive action limits, the substantial costs of that ongoing and future cleanup work represent obligations that historical pre-1986 carriers may be required 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.
