If you were diagnosed with mesothelioma, asbestosis, or another asbestos-related disease and you worked at Wheaton Power Station, contact an asbestos cancer lawyer in St. Louis or your region today — not next month, not after the next appointment. Today.

Power generation facilities like Wheaton ranked among the most heavily asbestos-contaminated industrial workplaces in America throughout the twentieth century. Steam-driven electricity production required materials that could withstand extreme heat in enclosed, poorly ventilated spaces — conditions where asbestos-containing materials were reportedly used throughout the facility and where microscopic fibers accumulated without workers’ knowledge or warning. Major manufacturers including Johns-Manville Corporation, Owens-Illinois, Armstrong World Industries, and Combustion Engineering are alleged to have known of grave health hazards decades before workers received any warning.

Workers who were employed at Wheaton and later relocated to Wisconsin or Illinois — or who traveled from Wisconsin or Illinois to work at Wheaton on construction or maintenance contracts — may have legal options in those states as well. The Mississippi River industrial corridor, stretching from the Quad Cities south through St. Louis and into the American Bottom, supplied skilled tradespeople to power stations throughout the Upper Midwest, including Wisconsin facilities. If you or a family member worked at Wheaton and has developed a serious illness, you may have legal claims against multiple asbestos manufacturers and possibly your employer or contractors. Wisconsin’s 3-year filing window is under active 2026 legislative threat — contact an asbestos lawsuit attorney today.

About Wheaton Power Station: Location and Operating History

Location and Regional Context

The Wheaton Power Station (also known as the Wheaton Generating Station) sits in Eau Claire, Wisconsin, in the Chippewa Valley region of west-central Wisconsin. The facility served as a primary piece of the area’s electric power infrastructure for decades, supplying energy to regional industrial and residential customers.

Ownership and Operating Structure

The Wheaton facility has been associated with:

Wisconsin Public Service (WPS) and its corporate predecessors and affiliate entities
Broader utility networks serving Wisconsin and Upper Michigan
Various holding companies and energy conglomerates throughout its operational history

Like virtually all coal- and oil-fired steam electric generating stations of comparable vintage, Wheaton was designed and built during an era — roughly the 1940s through 1970s, with some structures dating earlier — when asbestos-containing materials were considered the standard choice for thermal insulation, fireproofing, and equipment protection. Workers traveled from throughout the region — including from Missouri and Illinois — to work construction and maintenance outages at facilities like Wheaton. Many of those workers later returned home to communities along the Mississippi River industrial corridor, where they continued careers at facilities such as AmerenUE’s Labadie Energy Center in Franklin County, Missouri, Ameren’s Portage des Sioux Power Station in St. Charles County, Missouri, and Granite City Steel in Madison County, Illinois — facilities with their own documented histories of asbestos-containing material use.

Why Power Stations Used Asbestos-Containing Materials: The Engineering Context

Extreme Temperature Requirements and Material Selection

Steam-turbine power generation runs at extraordinary temperatures and pressures. Main steam lines operate above 1,000 degrees Fahrenheit at several hundred pounds per square inch. Open flame combustion systems create persistent fire hazards. Miles of piping and hundreds of equipment connections require insulation, gaskets, and sealing throughout every system.

Asbestos-containing materials dominated these applications because:

Chrysotile, amosite, and crocidolite asbestos fibers remain structurally stable at temperatures that destroy most organic materials
Asbestos transfers heat slowly, reducing energy waste
The material could be applied as plaster, wrapped as blankets, or molded into rigid pipe sections
It resists combustion — a practical necessity in facilities with open flame combustion
It was cheap and available throughout the twentieth century

These same engineering requirements drove asbestos-containing material use at Wisconsin and Illinois power stations and industrial facilities along the Mississippi River corridor. Workers who moved between facilities — or who built careers across multiple states in the same trades — accumulated exposures at each job site. If you worked at multiple power stations or industrial facilities, an asbestos attorney wisconsin can evaluate all your potential exposure locations.

What Manufacturers Knew — And When They Knew It

Major asbestos manufacturers — including Johns-Manville Corporation, Owens-Illinois, Armstrong World Industries, W.R. Grace, Combustion Engineering, and Eagle-Picher Industries — reportedly possessed internal knowledge for decades that asbestos fibers caused fatal diseases. Internal documents produced in litigation have shown these manufacturers allegedly suppressed, minimized, and delayed public disclosure of those hazards.

OSHA did not establish meaningful permissible exposure limits for asbestos until the 1970s. Enforcement in the utility sector was inconsistent. Workers at power stations like Wheaton reportedly labored for years or decades in environments where airborne fiber concentrations may have far exceeded safe levels — while manufacturers allegedly withheld the information that would have let them protect themselves. The same manufacturers supplied asbestos-containing materials to facilities throughout Wisconsin and Illinois, including chemical plants along the Missouri River, coal-fired generating stations on the Mississippi, and integrated steel mills in the American Bottom.

Asbestos-Containing Materials Reportedly Present at Wheaton Power Station

Based on construction types, equipment, and operational practices common to coal-fired steam generating stations of comparable vintage in the Midwest, the following categories of asbestos-containing materials were reportedly present at Wheaton.

Boiler Insulation and Refractory Components

Mid-twentieth century boilers were routinely built with:

Rigid block insulation from manufacturers such as Johns-Manville and Combustion Engineering
Finishing cements and plasters applied over insulation blocks
Refractory linings that in some formulations contained asbestos or were installed alongside asbestos-containing materials
Gaskets at flanged connections, inspection ports, and access panels throughout boiler systems

Workers who performed boiler construction, maintenance, tube repair, or overhauls may have been exposed to asbestos-containing materials from these components. Missouri boilermakers who traveled to Wisconsin facilities for outage work — including members of Boilermakers Local 27 based in the St. Louis area — may have encountered these same materials during their careers.

Pipe Covering and Thermal Insulation Systems

Steam lines, condensate return lines, feedwater heaters, and associated piping at Wheaton may have been insulated with asbestos-containing materials throughout much of the facility’s operational history:

Preformed pipe covering sections allegedly made with amosite asbestos from manufacturers including Johns-Manville, Armstrong World Industries, and Carey Manufacturing
Calcium silicate pipe insulation in earlier formulations reportedly containing asbestos
Pipe wrap and canvas jacketing used to finish and protect pipe insulation
Field-fabricated fitting covers and valve insulation made from asbestos-containing materials

Installing and removing pipe insulation produced one of the most hazardous asbestos exposure scenarios in industrial settings. Cutting, breaking, or pulling off pipe covering releases large quantities of airborne fibers. Members of Heat and Frost Insulators Local 1 in St. Louis — whose jurisdiction covered much of Wisconsin and portions of southern Illinois — reportedly traveled to power stations and industrial facilities throughout the region, including facilities in Wisconsin, on long-term construction and maintenance assignments. If you are an insulator with an asbestos exposure history, consult an asbestos cancer lawyer in St. Louis or your area immediately.

Turbine and Pump Insulation Systems

Steam turbines and associated pumps reportedly required extensive insulation with asbestos-containing materials:

Turbine casing insulation blankets and block insulation
Gaskets throughout turbine components and steam connections
Packing in turbine glands and valve packing systems
Pump insulation on feedwater pumps, circulating water pumps, and condensate extraction pumps

These turbine insulation systems were broadly standardized across Midwestern power stations. Workers who insulated or maintained turbines at Wheaton may have encountered the same manufacturers’ products and the same installation and removal practices used at Missouri facilities such as Labadie and Portage des Sioux.

Electrical Infrastructure and Switchgear Systems

Electrical systems at power stations may have incorporated asbestos-containing materials:

Panels and switchgear from General Electric, Westinghouse, and Square D, which reportedly included asbestos-containing arc suppression components, insulation boards, and internal gaskets
Cable trays and conduit penetration seals with asbestos-containing fire-stopping materials
Motor insulation on pumps and fans in some applications

Building Structure and Fireproofing Materials

The buildings housing power generation equipment at Wheaton reportedly contained:

Sprayed-on fireproofing on structural steel from manufacturers such as W.R. Grace, whose Monokote product is alleged to have contained asbestos fibers
Ceiling tiles and floor tiles in control rooms, office areas, and mechanical spaces, reportedly from Armstrong World Industries and Georgia-Pacific
Transite board and panels — asbestos-cement products from Johns-Manville and others — used for partition walls, electrical backing boards, and exterior panels
Roofing materials and mastics in building envelope construction

W.R. Grace’s products were reportedly distributed and used throughout the Mississippi River industrial corridor, including at Missouri and Illinois facilities. Grace’s operations in the region — including alleged connections to Monsanto’s chemical complex in St. Louis County — are alleged to have contributed to asbestos-containing material contamination across multiple industrial sites.

Gaskets, Packing, and Sealing Materials Throughout the Facility

Gaskets and packing were present at virtually every flanged pipe joint, valve, pump, and heat exchanger connection throughout the facility. Many products reportedly contained 80% or more asbestos fiber by weight. Manufacturers associated with these asbestos-containing products include Garlock Sealing Technologies (Coltec Industries), Flexitallic, John Crane, and A.W. Chesterton.

Workers replaced these materials repeatedly during maintenance outages. Removing asbestos-containing gaskets — by scraping, grinding, or wire-brushing old material from flange faces — released asbestos fibers into the air. Workers performing removal and those nearby may have been exposed. Members of UA Local 562 — the United Association of Plumbers and Pipefitters serving the greater St. Louis area, one of the largest UA locals in the country — reportedly traveled to power station outages throughout the Midwest on a regular basis, performing gasket and packing work alongside local trades.

Occupations and Trades at Risk: Who May Have Faced Asbestos Exposure

Exposure at power stations like Wheaton was not limited to one trade. Many occupations brought workers into direct contact with asbestos-containing materials. Bystander exposure — inhaling fibers disturbed by other workers — affected virtually everyone working in the facility during active insulation, demolition, or maintenance work.

Insulators and Thermal Protection Specialists

Insulators working at Wheaton may have:

Installed asbestos-containing pipe insulation during original construction and subsequent modifications
Removed and replaced pipe covering during routine maintenance and emergency repairs
Mixed, applied, and finished asbestos-containing cements and plasters on irregular surfaces
Cut and shaped preformed ins
