Asbestos Exposure at Power Plants: Why Weston Matters for Wisconsin workers

Facility Overview and Operational History

Weston Generating Station (also known as the J.P. Madgett / Weston Power Plant) is a coal-fired electrical generating facility in Rothschild, Wisconsin, Marathon County, along the Wisconsin River. Wisconsin Public Service Corporation (WPS), a subsidiary of WEC Energy Group (formerly Integrys Energy Group), owns and operates the plant.

The facility was built in phases:

Weston Unit 1: Commissioned approximately 1958
Weston Unit 2: Commissioned approximately 1963
Weston Unit 3: Commissioned approximately 1974 — a major expansion
Weston Unit 4: Commissioned 2008 — built to modern environmental standards

Units 1, 2, and 3 were designed and constructed when asbestos-containing materials were standard components of power generation infrastructure. Workers employed during construction, operations, and maintenance from the 1950s through the early 1990s may have been exposed to asbestos-containing materials on the job.

Wisconsin Public Service Corporation employed or contracted thousands of workers at Weston over its decades of operation, including:

Direct utility employees
Construction and skilled trades contractors — including members of Heat and Frost Insulators Local 1 (St. Louis) and other regional union locals who supplied temporary project crews to power plant construction and outage work across the upper Midwest
Maintenance specialists
Equipment service representatives

The Missouri Connection: Union Tradespeople and the Mississippi River Corridor

Missouri and Illinois tradespeople regularly worked at power facilities well beyond their home states. The Mississippi River industrial corridor — running from the St. Louis metropolitan area through the upper Midwest — created a network of power plants, refineries, and industrial sites where members of Heat and Frost Insulators Local 1, UA Local 562 (Plumbers and Pipefitters, St. Louis), and Boilermakers Local 27 (St. Louis) may have traveled for construction and outage work.

If you are a Wisconsin or Illinois resident who worked at Weston at any point, your legal rights may be governed in part by Wisconsin law and the Wisconsin’s statute of limitations for asbestos lawsuits. A Wisconsin-based asbestos attorney can evaluate whether claims belong in Wisconsin courts, Wisconsin courts, or both.

Who Was at Risk? High-Risk Occupations at Weston Power Plant

Research on occupational asbestos exposure in the power generation industry consistently identifies specific trades as carrying elevated risk of asbestos-related disease. Workers in the following occupations who worked at Weston Power Plant may have been exposed to asbestos-containing materials.

Insulators and Insulation Workers

Insulators directly installed, removed, and replaced asbestos-containing pipe insulation, block insulation, and blanket insulation on steam lines, boiler surfaces, and turbine casings. Cutting, trimming, and fitting insulation generated heavy concentrations of airborne asbestos fibers. Workers in this trade may have handled asbestos-containing products such as Kaylo (Owens-Illinois/Owens Corning), Unibestos, Thermobestos, and Pabco insulation materials. Heat and Frost Insulators Local 1 (St. Louis) and affiliated Midwest locals reportedly supplied workers to major power plant construction and maintenance projects throughout the upper Midwest during this period.

Pipefitters and Steamfitters

Pipefitters worked on high-temperature steam and feedwater systems heavily insulated with asbestos-containing materials. Accessing pipe flanges and valves required disturbing existing insulation. Workers in this trade also replaced asbestos-containing gaskets and packing on valves, flanges, and pumps — products supplied by Garlock Sealing Technologies, Crane Co. (John Crane), and Armstrong World Industries. Members of UA Local 562 (St. Louis) and other Missouri and Illinois pipefitter locals may have worked at Weston during major construction phases or scheduled outages.

Boilermakers

Boilermakers performed construction, maintenance, and repair on large boilers and may have been exposed to asbestos-containing refractory materials, boiler insulation, rope gaskets, and furnace cement. They often worked inside boilers during outages — precisely when multiple trades were simultaneously disturbing asbestos-containing materials throughout the unit. Boilermakers Local 27 (St. Louis) members and affiliated Midwest locals who traveled to Wisconsin job sites may have been exposed to asbestos-containing materials at Weston during construction and major outage work.

Additional At-Risk Occupations

Electricians: Installed and maintained asbestos-containing electrical panels, switchgear components, and electrical insulation materials
Millwrights: Machinery maintenance and turbine work may have involved direct contact with asbestos-containing insulation supplied by General Electric, Westinghouse, and Combustion Engineering
Laborers and Maintenance Workers: Cleanup and general work in areas where asbestos-containing materials were being disturbed created bystander exposure
Plant Operators and Painters: Routine contact with insulated pipe systems; surface preparation near ACMs released fibers
Sheet Metal Workers: Installed ductwork and casings adjacent to asbestos-containing insulation

If your occupation appears on this list — or if you performed work at Weston in any capacity during the decades identified above — and you have since received a diagnosis of mesothelioma, asbestosis, or lung cancer, you may have a viable asbestos claim.

Why Asbestos Was Standard at Weston and Other Midwest Power Plants

The Thermal and Industrial Requirements

Coal-fired power plants operate under conditions that drove widespread use of asbestos-containing materials through the mid-twentieth century:

Steam generated at temperatures exceeding 1,000°F
Pressures measured in hundreds of pounds per square inch
Thermal insulation required on high-pressure steam lines, boiler casings, turbine bodies, feedwater heaters, condensers, and economizers

Asbestos-containing insulation dominated these applications because manufacturers and facility operators prized its fire-resistance, chemical stability, and cost-effectiveness.

Equipment Manufacturers Built Asbestos Into Their Specifications

Major manufacturers — including General Electric, Westinghouse, Combustion Engineering, Babcock & Wilcox, and Foster Wheeler — incorporated asbestos-containing materials into boilers, turbines, generators, and associated equipment as a matter of routine engineering specification. Asbestos-containing insulation from Johns-Manville, Owens-Illinois, Owens Corning, Eagle-Picher, Georgia-Pacific, and Celotex were standard for Midwestern power plant construction. These same product lines appear repeatedly in litigation arising from Wisconsin-area facilities, including:

Labadie Power Plant (Franklin County)
Portage des Sioux Power Plant (St. Charles County)
Granite City Steel (Madison County, Illinois)

The manufacturer and distributor networks serving Wisconsin utilities were the same networks supplying plants throughout the Mississippi River corridor.

Regulatory Transition Was Gradual — and Workers Paid the Price

Early 1970s: EPA began issuing asbestos regulations; OSHA promulgated its first asbestos exposure standards in 1971
Late 1970s–1980s: Power generation facilities began phasing out ACMs, but the transition was slow and uneven
1980s–1990s: Existing asbestos-containing insulation remained in place at many facilities, continuing to create exposure risk during maintenance and renovation work

The science on asbestos toxicity was well-established decades before these regulations took effect. Internal documents produced in asbestos litigation have shown that manufacturers knew of the health risks long before workers were warned.

Timeline: Alleged Asbestos-Containing Materials Exposure at Weston Power Plant

1950s — Original Unit Construction

During construction of Weston Unit 1, asbestos-containing insulation, gaskets, packing materials, and fireproofing products supplied by Johns-Manville, Owens-Illinois, and Crane Co. are alleged to have been installed throughout the facility. Construction tradespeople — insulators, pipefitters, boilermakers, and electricians — may have been exposed to asbestos-containing materials during installation of equipment manufactured by General Electric and Westinghouse. Missouri and Illinois union members who traveled to Wisconsin for this construction work may have been among those allegedly exposed.

1960s — Unit 2 Construction and Continued Operations

Construction of Weston Unit 2 introduced additional asbestos-containing materials from major manufacturers. Maintenance workers, operators, and contractor personnel may have encountered asbestos-containing pipe insulation — including Kaylo (Owens-Illinois) and Unibestos — as well as boiler insulation and equipment gaskets from Garlock and Armstrong World Industries. The same Kaylo product alleged to have been used at Labadie and Portage des Sioux was a standard insulation specification at coal-fired generating stations throughout this region.

1970s — Unit 3 Construction and the Regulatory Transition

Construction of Weston Unit 3 proceeded while awareness of asbestos hazards was growing and OSHA’s first asbestos standards were nominally in effect. Asbestos-containing materials from Johns-Manville, Owens Corning, W.R. Grace, and Eagle-Picher nonetheless remained in widespread use. Workers on Unit 3 construction — potentially including members of Heat and Frost Insulators Local 1 and UA Local 562 — may have been exposed to asbestos-containing materials during this critical expansion phase. The gap between regulatory intent and field compliance was well-documented at industrial sites throughout this era.
