Industrial & Manufacturing cleanup site — Restorical Research
Ultra Plating Corp - Site 2
Green Bay, Brown County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1955. 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 been in continuous industrial use since at least 1955, when metal plating and finishing operations began, though earlier industrial activities at the site — including paper manufacturing, welding and boiler works, and lumber and coal yards — date back to 1883. Chromium, cyanide, cadmium, VOCs, TCE, PAHs, and PCBs have been confirmed in soil and groundwater, consistent with decades of plating solution handling and direct discharge to the municipal sewer system. Groundwater contamination has migrated off-site to adjacent properties, with elevated cyanide and thallium concentrations detected beyond the property boundary, and Wisconsin DNR issued a vapor intrusion and TCE reminder letter in 2021 reflecting ongoing TCE in groundwater. Multiple rounds of groundwater sampling have been conducted under the Wisconsin DNR Environmental Remediation Program, with monitoring events documented through 2026. 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.

Metal plating and finishing operations at this property began more than three decades before 1986, with industrial use at the site extending back to the late nineteenth century. The ongoing groundwater investigation, off-site contamination assessment, vapor intrusion evaluation, and remediation work ahead under Wisconsin DNR 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.
