Industrial & Manufacturing cleanup site — Restorical Research

Oshkosh, Winnebago County

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1890. 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 along the Fox River has been in industrial use since before 1890, with documented operations including a railroad spur and freight yard (1903–1957), a plywood warehouse (circa 1960–1971), and boat building (1971–1974). Historic fill deposited over decades of industrial development extends six to ten feet below ground surface and contains elevated concentrations of RCRA metals (arsenic, chromium, lead), polycyclic aromatic hydrocarbons (PAHs), and volatile organic compounds (VOCs). Groundwater sampling has confirmed benzo(b)fluoranthene above the Wisconsin NR 140 Preventive Action Limit, with groundwater flow directed northeast toward the Fox River. The site is an active Wisconsin DNR Environmental Remediation Program case with investigation and remediation work continuing. 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 railroad and freight yard use from 1903 to 1957, plywood warehousing from approximately 1960 to 1971, and boat building from 1971 to 1974 — all took place decades before 1986, depositing historic fill containing RCRA metals, PAHs, and VOCs that now extend six to ten feet below ground surface and have impacted groundwater flowing toward the Fox River. The ongoing site investigation, soil remediation, groundwater monitoring, and environmental compliance work required under the Wisconsin DNR Environmental Remediation Program represent future costs that the historical carriers insuring the businesses that operated here before 1986 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.
