Dry Cleaner cleanup site — Restorical Research
Portage Cleaners Inc
Portage, Columbia County

Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1970. 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.

Dry-cleaning operations using tetrachloroethylene (PCE) were conducted at this property from the 1970s through approximately 1996, across multiple buildings — including a third structure between the east and west buildings that was destroyed by fire in 1990. A PCE and trichloroethylene (TCE) groundwater plume extends approximately 120 feet off-site to the east, with concentrations exceeding Wisconsin DNR enforcement standards at both on-site and off-site monitoring wells. Vapor intrusion assessments have been conducted at multiple neighboring residential and commercial properties, with vapor action levels and vapor risk screening levels exceeded, prompting ongoing Wisconsin DNR Environmental Remediation Program 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.

Dry-cleaning operations at this property began in the 1970s and continued through the mid-1980s, placing more than a decade of PCE-based solvent use squarely in the pre-1986 window. The ongoing groundwater remediation, off-site vapor intrusion monitoring, and compliance work required to address the migrating contaminant plume 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.
