Industrial & Manufacturing cleanup site — Restorical Research
Advance Die Cast - Plant 2
Milwaukee, Milwaukee County

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1900. 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 industrial use since the early 1900s, with decades of aluminum and zinc die casting manufacturing involving cutting oils, greases, degreasers, solvents, and suspect underground storage tanks. A Phase II Environmental Site Assessment confirmed extensive groundwater contamination across eight temporary monitoring wells, with benzene concentrations nearly 70 times the Wisconsin NR 140 enforcement standard, along with polycyclic aromatic hydrocarbons (chrysene, naphthalene, benzo(b)fluoranthene) and heavy metals including arsenic, cadmium, chromium, lead, and mercury at levels exceeding NR 140 standards. The site is an active Wisconsin DNR Environmental Remediation Program case with a site investigation workplan under review. 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 decades of aluminum and zinc die casting involving cutting oils, solvents, degreasers, and underground storage tanks — began in the early 1900s and continued through the years preceding 1986. The site investigation now under review by the Wisconsin DNR Environmental Remediation Program, remediation of extensive groundwater contamination where benzene alone exceeds NR 140 enforcement standards by nearly 70 times alongside polycyclic aromatic hydrocarbons and heavy metals, and the long-term monitoring needed to achieve compliance represent substantial future costs that the 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.
