⚠️ URGENT Wisconsin FILING DEADLINE WARNING

Wisconsin’s asbestos statute of limitations gives you 5 years from your diagnosis date to file a claim — and that window does not pause while you wait for a second opinion, grieve a family member’s death, or hope the science changes.

Under Wis. Stat. § 893.54, Wisconsin provides a 5-year filing window measured from your diagnosis date — not from when you were exposed. Waiting for “more time” is a strategy that has cost Wisconsin asbestos victims their legal rights. **> If you or a family member has been diagnosed with mesothelioma, asbestosis, or another asbestos-related disease, call a qualified Asbestos Cancer Lawyer Wisconsin today. The clock is running now, not from some future date.

Workers at the Nemadji Trail Energy Center in Superior, Wisconsin — and their families — may have been exposed to asbestos-containing materials linked to mesothelioma, asbestosis, and other serious lung diseases. Power generation facilities rely on insulation, gaskets, and fireproofing products that historically contained asbestos from manufacturers including Johns-Manville, Owens-Illinois, Combustion Engineering, and Armstrong World Industries. Construction, maintenance, and renovation work at such facilities has exposed thousands of skilled trades workers to toxic asbestos fibers over the course of careers that often spanned multiple facilities and multiple states.

Workers or family members diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease after working at this facility may be entitled to substantial compensation through litigation, asbestos trust fund claims, or settlements.

Time is a critical factor. Wisconsin gives asbestos disease victims 3 years from diagnosis to file claims under Wis. Stat. § 893.54 — and pending 2026 legislation threatens to make filing significantly more burdensome. Missouri and Illinois residents who worked at NTEC or at comparable power generation facilities throughout the Upper Midwest share legal rights and filing options with workers who spent their careers in the Mississippi River industrial corridor — from the Labadie Energy Center in Franklin County, Missouri, to the Portage des Sioux plant in St. Charles County, to the Granite City Steel complex in Madison County, Illinois. The same manufacturers, the same products, and the same decades-long concealment of known hazards appear throughout this interconnected industrial region. The same urgency applies to every one of those workers.

What Is Nemadji Trail Energy Center?

Facility Overview

Nemadji Trail Energy Center (NTEC) is a natural gas-fired combined-cycle power generation facility in Superior, Wisconsin, Douglas County, along the southwestern shore of Lake Superior. The facility serves Minnesota Power and other regional utilities through agreements coordinated with the Midcontinent Independent System Operator (MISO).

Superior’s Industrial History and Asbestos Exposure Risk

Superior sits at the western tip of Lake Superior and spent decades as one of the Upper Midwest’s most concentrated heavy industrial corridors. The region hosted:

  • Iron ore processing and shipping
  • Coal distribution and handling
  • Petroleum refining and storage
  • Marine vessel construction and repair
  • Power generation and transmission infrastructure

Every one of those industries relied on asbestos-containing materials for insulation, fireproofing, and mechanical system components. Manufacturers including Johns-Manville, Owens-Illinois, Owens Corning, W.R. Grace, and Combustion Engineering supplied pipe insulation, gaskets, packing materials, and spray-applied fireproofing compounds throughout the Superior industrial corridor for most of the twentieth century.

Older infrastructure at and near the NTEC site — including legacy pipework, boiler systems, turbine insulation, and building materials — may have incorporated asbestos-containing materials such as Kaylo pipe insulation, Thermobestos products, and Monokote spray fireproofing, consistent with standard industrial practice during that era.

The industrial heritage of Superior, Wisconsin connects directly to the broader Mississippi River and Great Lakes industrial corridor running southward through Illinois and Missouri. Many of the same contractors, union members, and equipment manufacturers that operated in the Superior region also worked throughout this corridor — at facilities including AmerenUE’s Labadie Energy Center in Franklin County, Missouri; the Portage des Sioux generating station in St. Charles County, Missouri; the Monsanto chemical complex in St. Louis; and the Granite City Steel facility in Madison County, Illinois. The asbestos-containing products allegedly used at these facilities were frequently identical, sourced from the same Johns-Manville, Owens-Illinois, and Combustion Engineering supply chains.

Construction, Renovation, and Asbestos Exposure Events

Construction, equipment upgrades, demolition, and abatement work at industrial facilities have historically released asbestos fibers in quantities far exceeding safe exposure thresholds. Workers who may have been employed at Nemadji Trail Energy Center or at predecessor facilities on or near this site — including contractors, subcontractors, maintenance personnel, and skilled trades workers — may have been exposed to asbestos-containing materials during their employment.

Laborers, pipefitters, insulators, electricians, and boilermakers from regional unions including Heat and Frost Insulators Local 1 (St. Louis), Heat and Frost Insulators Local 27 (Kansas City), UA Local 562 (St. Louis plumbers and pipefitters), and Boilermakers Local 27 (St. Louis) reportedly traveled to and worked at facilities throughout the Upper Midwest, including NTEC and related power generation assets. This travel and contract work pattern is well-documented in asbestos litigation involving Missouri and Illinois union members who worked at out-of-state industrial facilities during peak construction and maintenance periods.

For any Wisconsin or Illinois worker who may have been exposed at NTEC and has since received a diagnosis of mesothelioma or asbestosis, the legal clock is already running.

Why Power Plants Use Asbestos-Containing Materials

The Engineering Case for Industrial Asbestos

Asbestos is a naturally occurring fibrous silicate mineral with physical properties that drove its adoption across virtually every heavy industry from the late nineteenth century through the 1970s and beyond:

  • Heat resistance: Asbestos fibers remain stable above 2,000°F, making them the default choice for boilers, turbines, and high-pressure steam lines
  • Electrical non-conductivity: Asbestos materials insulated generating equipment reliably and cheaply
  • Tensile strength: Asbestos fibers reinforced composite materials, gaskets, and packing compounds
  • Chemical resistance: ACMs withstood steam, oil, acids, and industrial chemicals without degrading
  • Low cost: Asbestos was cheap, abundant, and easily processed into hundreds of distinct industrial products
  • Fire resistance: Regulatory and insurance requirements at industrial facilities demanded fire-resistant materials, and asbestos was the industry-standard solution for decades

Power Plants: Among the Most Asbestos-Intensive Industrial Environments

Coal-fired, oil-fired, and early natural gas power plants historically ranked among the most asbestos-intensive worksites in the United States. The reasons are structural:

  • High-pressure, high-temperature steam systems required extensive pipe and equipment insulation, historically supplied by Johns-Manville and Owens-Illinois
  • Large boiler installations were wrapped in multiple layers of insulating materials — Kaylo, Thermobestos, and similar products reportedly containing chrysotile, amosite, or crocidolite asbestos fibers
  • Turbine and generator systems used asbestos-containing gaskets from Garlock Sealing Technologies, along with seals, packing, and insulating blankets
  • Electrical switchgear and control rooms were built with asbestos-containing panels — Unibestos and Gold Bond products — and fireproofing compounds such as Monokote from W.R. Grace and Armstrong World Industries
  • Cooling systems and heat exchangers were sealed with asbestos-containing gaskets and packing from manufacturers including Eagle-Picher and Crane Co.
  • Building construction materials included asbestos cement board, roofing products from Celotex and Georgia-Pacific, floor tiles, ceiling tiles, and spray-applied fireproofing compounds such as Aircell and Monokote

This pattern is consistent with documented conditions at Missouri power generation facilities including AmerenUE’s Labadie Energy Center, the Portage des Sioux plant, and Union Electric’s Meramec generating station in St. Louis County — as well as at Illinois industrial facilities in Madison County and St. Clair County along the Mississippi River corridor.

What Manufacturers Knew — and Concealed

Internal corporate documents produced in asbestos litigation have repeatedly shown that major manufacturers knew their products were lethal and concealed that knowledge from workers and facility operators for decades.

Johns-Manville — the dominant supplier of industrial insulation products throughout the twentieth century — held internal medical records documenting asbestos-caused mesothelioma and asbestosis dating to the 1930s and 1940s. The company continued marketing products such as Kaylo pipe insulation without adequate worker warnings. Johns-Manville’s concealment of these hazards has been extensively documented in litigation filed in Milwaukee County Circuit Court and in Madison County, Illinois Circuit Court.

Owens-Illinois, Owens Corning, and W.R. Grace similarly manufactured and distributed asbestos-containing spray fireproofing, pipe insulation, and cement products while withholding known health risks from the workers applying them. Owens-Illinois operated a significant glass and materials manufacturing presence in the greater St. Louis region, and its products were routinely specified at Missouri and Illinois power generation and industrial facilities throughout the Mississippi River corridor.

The Regulatory Shift Away From Asbestos

EPA and OSHA moved progressively to restrict asbestos use beginning in the early 1970s:

  • 1972: OSHA issued its first permissible exposure limits for asbestos in the workplace
  • 1973–1994: Permissible exposure standards tightened repeatedly as the science became impossible to ignore
  • 1989 and beyond: Ongoing regulatory restrictions on new asbestos-containing products

Asbestos was never universally banned across all applications. Legacy materials installed before the 1980s remained in place — and many still remain — at facilities built or significantly modified before that regulatory shift. Workers performing maintenance, renovation, or demolition on older power plant infrastructure may have been exposed to asbestos-containing materials years or decades after original construction. This phenomenon — sometimes called secondary disturbance exposure — accounts for a substantial proportion of mesothelioma diagnoses among maintenance workers and skilled trades members.
