Industrial & Manufacturing cleanup site — Restorical Research
Hydrite Chemical
Cottage Grove, Dane County

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1970. Historical insurance policies issued during operations at this property and through 1986 could help fund the multi-phase investigation and remediation work ahead under Wisconsin DNR oversight.

Chemical manufacturing operations at this property began in 1970 and included hazardous waste treatment, storage, and disposal activities that led to significant environmental contamination, with the facility designated as a RCRA corrective action site since 1982. Chlorinated solvents — including tetrachloroethylene (PCE), trichloroethylene (TCE), and 1,4-dioxane — have contaminated soil, groundwater, and surface water, with the plume extending well beyond the property into the surrounding community. Active remediation infrastructure includes a hydraulic barrier system pumping approximately 11.2 million gallons of contaminated groundwater per quarter and a shallow plume remediation system operating in an adjacent public park at approximately 7 million gallons per quarter. Vapor intrusion assessments have been conducted at neighboring residential properties, and annual surface water sampling continues at nearby ponds, drainage ditches, and Koshkonong Creek under 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.

Chemical manufacturing and hazardous waste operations at this facility began in 1970 and continued through the pre-1986 period, placing more than fifteen years of contaminating activity within the pre-1986 window. The extensive ongoing remediation — including hydraulic barrier operation, groundwater extraction and treatment, surface water monitoring, and vapor intrusion management across the surrounding community — represents substantial 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.
