Landfill cleanup site — Restorical Research
West Allis Waste Transfer Station
West Allis, Milwaukee County

Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1946. 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 municipal incinerator site beginning before 1949 and was also the location of a 1946 creek rerouting project in which the former Kinnikinnick Creek channel was backfilled with fill material. PCBs, polycyclic aromatic hydrocarbons (PAHs), and metals have been confirmed in soil consistent with decades of historic fill and incinerator operations, and benzene has been detected above the Wisconsin NR 140 Enforcement Standard in groundwater monitoring wells. The site is an active Wisconsin DNR Environmental Remediation Program case with an approved remedial action plan calling for engineering and institutional controls along with monitored natural attenuation of contaminated groundwater. 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.

Incinerator operations and disposal of historic fill material at this property began before 1949 and continued for decades prior to 1986, producing soil contamination from PCBs, PAHs, and metals as well as benzene in groundwater above the NR 140 Enforcement Standard. The ongoing groundwater monitoring, implementation of engineering and institutional controls under the approved remedial action plan, and any additional remediation required to achieve Wisconsin DNR closure standards 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.
