Industrial & Manufacturing cleanup site — Restorical Research
Mayfield Transfer Company Property - Cvocs
Milwaukee, Milwaukee County

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 documented history of industrial use, with chlorinated volatile organic compounds — including trichloroethylene (TCE), vinyl chloride, and cis-1,2-dichloroethylene (cis-1,2-DCE) — confirmed in groundwater at concentrations significantly exceeding Wisconsin NR 140 Enforcement Standards. Vinyl chloride was measured at more than 41 times its enforcement standard, and TCE exceeded its standard by more than three times across multiple monitoring wells. A prior Environmental Remediation Program case was opened at this same property in 1994, indicating that contamination has been present for decades, and the current ERP case remains open with active investigation under Wisconsin DNR oversight. 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.

The chlorinated solvents confirmed in groundwater at this property — TCE, vinyl chloride, and cis-1,2-DCE — are characteristic industrial degreasers whose widespread use predates 1986, and the opening of an initial Environmental Remediation Program case at this same property in 1994 confirms that contamination from pre-1986 industrial operations has persisted here for decades. The ongoing groundwater investigation, remediation of NR 140 Enforcement Standard exceedances — including vinyl chloride concentrations measured at more than 41 times the applicable standard — and the long-term monitoring required to achieve Wisconsin DNR closure represent future costs that historical pre-1986 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.
