Mesothelioma Lawyer Wisconsin: Asbestos Exposure at We Energies Power Plants

For Former Workers, Families, and Mesothelioma Victims

**URGENT: If you have been diagnosed with mesothelioma or another asbestos-related disease, Wisconsin law gives you five years to file a personal injury claim under Wis. Stat. § 893.54—and that clock runs from your diagnosis date, not from the date of exposure. Pending legislation,

Why Former We Energies Workers Are Filing Asbestos Claims Now

For decades, workers at We Energies and its predecessor utilities—Wisconsin Electric Power Company (WEPCO) and Milwaukee Electric Railway and Light Company—built and maintained the electrical and steam infrastructure that powered southeastern Wisconsin. Pipefitters, insulators, boilermakers, electricians, and maintenance crews belonging to Heat and Frost Insulators Local 19 (Milwaukee) and Plumbers and Pipefitters UA Local 562 performed skilled work they were told was safe.

What they were not told: the asbestos-containing materials they may have cut, sawed, wrapped, and removed throughout these facilities allegedly came from manufacturers including Johns-Manville, Owens-Illinois, Armstrong World Industries, and Garlock Sealing Technologies. Mesothelioma and asbestosis may not appear until 20 to 50 years after exposure. Workers who spent careers at these plants are receiving diagnoses today.

If you or a family member worked at a We Energies power plant and have been diagnosed with mesothelioma or asbestosis, an asbestos attorney can evaluate your legal rights immediately. Wisconsin residents pursuing claims face a five-year statute of limitations under Wis. Stat. § 893.54—measured from diagnosis. This page explains what allegedly happened at these facilities, where the hazardous materials reportedly came from, and what legal options remain open.

Section 1: We Energies Corporate History and Asbestos Exposure

Why Corporate History Determines Who You Sue

Asbestos-containing materials were most heavily used at power plants between approximately 1930 and 1980. Liability for that era traces through predecessor companies that purchased, specified, or installed those materials—not necessarily through today’s corporate name on the building. Understanding that chain is essential to building a viable claim.

The relevant corporate succession:

• Milwaukee Electric Railway and Light Company — one of Milwaukee’s earliest electric utilities, founded in the 1890s
• Wisconsin Electric Power Company (WEPCO) — the primary operating entity through most of the twentieth century, running power stations throughout southeastern Wisconsin
• Wisconsin Gas Company — merged operations that brought additional plant infrastructure under the same corporate umbrella
• We Energies — the current trade name, adopted in the early 2000s following restructuring under WEC Energy Group

Claims may run against We Energies, WEC Energy Group, and directly against product manufacturers—including Johns-Manville, Owens-Illinois, Armstrong World Industries, Combustion Engineering, Garlock Sealing Technologies, W.R. Grace, and Crane Co.—that allegedly supplied asbestos-containing products to these facilities.

Major We Energies / WEPCO Generating Stations

Valley Power Plant

Located along the Menomonee River in Milwaukee’s Menomonee Valley industrial corridor, Valley Power Plant reportedly operated for decades as a combined heat and power (CHP) cogeneration facility supplying electricity and steam to downtown Milwaukee buildings and institutions.

Steam generation facilities carry elevated asbestos risk. These systems require extensive high-temperature insulation, and for most of the twentieth century that insulation was manufactured with asbestos-containing materials. Workers at Valley Power Plant may have been exposed to asbestos-containing pipe insulation, boiler lagging, and sprayed fireproofing products—including trade names such as Kaylo, Thermobestos, and Monokote—allegedly supplied by Johns-Manville, Owens-Illinois, and Owens Corning. Valley Power Plant is the subject of NESHAP asbestos abatement notifications filed with the Wisconsin Department of Natural Resources in connection with renovation and demolition work (documented in NESHAP abatement records filed with WDNR).

Oak Creek Power Plant

The Oak Creek generating complex sits on Lake Michigan’s western shore south of Milwaukee. Construction reportedly began in phases in the 1950s, with additional units added through subsequent decades. For many years it was one of the largest coal-fired generating stations in Wisconsin.

Large coal-fired boilers and turbine halls characteristically incorporated asbestos-containing insulation, gaskets, packing, and fireproofing supplied by manufacturers including Combustion Engineering, Garlock Sealing Technologies, and John Crane. Workers at Oak Creek may have been exposed to asbestos-containing pipe insulation, boiler block insulation, flange gaskets, and spray-applied fireproofing materials (documented in NESHAP abatement records filed with WDNR).

Port Washington Power Plant

The Port Washington facility, located north of Milwaukee, was one of WEPCO’s major generating stations. Original units were constructed beginning in the 1930s and expanded through subsequent decades—placing the primary construction period squarely within the years of heaviest asbestos-containing material use in American industrial construction.

Workers at Port Washington may have been exposed to asbestos-containing thermal insulation, floor tiles, and gasket materials allegedly supplied by Johns-Manville, Armstrong World Industries, Owens-Illinois, and Garlock.

Elm Road Generating Station

The Elm Road facility in Oak Creek is a mid-to-late twentieth-century generating complex. Workers involved in construction, and later in the removal or replacement of older infrastructure components, may have encountered legacy asbestos-containing materials during renovation phases—including pipe insulation, equipment covers, and refractory materials.

Milwaukee Steam Distribution Infrastructure

We Energies and predecessor companies operated extensive steam distribution infrastructure throughout downtown Milwaukee: underground steam tunnels, above-ground steam mains, condensate return lines, and building-integrated distribution networks. This system allegedly relied heavily on asbestos-containing pipe insulation and related materials from manufacturers including Johns-Manville and Owens-Illinois. Workers maintaining, repairing, or renovating these systems over the course of a career may have been exposed to wrapped and block pipe insulation products repeatedly—often in confined spaces with no ventilation.

Section 2: Asbestos Exposure in Power Generation

Why Asbestos Was Used Throughout These Facilities

Power generation is a heat management enterprise. Coal-fired and natural gas generating stations combust fuel to produce superheated steam that drives turbines. Operating temperatures often exceed 1,000°F; line pressures reach hundreds of pounds per square inch. Containing that energy required massive quantities of insulation, gaskets, packing materials, and fireproofing—and for most of the twentieth century, asbestos-containing materials were the industry standard for every one of those applications.

No commercially available material matched asbestos across all the properties power plant operators required:

• Extreme heat resistance — asbestos fibers remain stable at temperatures that destroy most alternatives
• Tensile strength — asbestos fibers can be woven into cloth, rope, or reinforcing material
• Chemical inertness — asbestos resists acids, alkalis, and corrosive steam condensate
• Thermal and acoustic insulation — asbestos-containing products reduced heat loss and noise across large surface areas
• Low cost — American asbestos mines in Libby, Montana, and Canadian sources kept prices low throughout the mid-twentieth century

Virtually every component of a mid-century steam generating station—boiler drums, turbine casings, valve covers, flange connections, expansion joints—potentially incorporated asbestos-containing materials.

Manufacturers of Asbestos-Containing Products

These manufacturers actively marketed asbestos-containing products to power utilities operating facilities like those at We Energies:

Trade-Name Asbestos-Containing Products at We Energies Facilities

Evidence and facility records suggest the following trade-name asbestos-containing products were present at We Energies and predecessor WEPCO facilities:

• Kaylo — Johns-Manville high-temperature pipe insulation
• Thermobestos — Johns-Manville insulation cement
• Aircell — asbestos-containing insulation product
• Monokote — spray-applied fireproofing
• Unibestos — asbestos-containing insulation product
• Cranite — Crane Co. asbestos-containing refractory material
• Superex — asbestos-containing product line
• Gold Bond — Johns-Manville asbestos-containing floor tiles and related products
• Pabco — asbestos-containing roofing materials

What the Manufacturers Knew—and When They Knew It

This is not a case of unknown hazards. Internal documents produced in decades of asbestos litigation have established that major manufacturers—including Johns-Manville and Owens-Illinois—were aware of the connection between asbestos exposure and fatal lung disease as far back as the 1930s and 1940s. These companies allegedly continued marketing their products without adequate warnings long after that knowledge existed internally.

Workers at We Energies power plants reportedly handled asbestos-containing materials for years without respirators, without hazard warnings on product labels, and without the industrial hygiene controls that basic occupational safety standards now require. The concealment of known dangers is central to why these cases result in substantial verdicts and settlements.

Section 3: NESHAP Records and Asbestos Evidence

Understanding NESHAP Requirements

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for asbestos, codified at 40 C.F.R. Part 61, Subpart M, is the primary federal regulation governing asbestos disturbance at industrial facilities. Before any renovation or demolition that will disturb regulated asbestos-containing materials, facility owners must:

• Inspect for asbestos-containing materials
• Notify the appropriate regulatory authority—in Wisconsin, the WDNR—before work begins
• Wet-down and remove friable asbestos-containing materials before general demolition proceeds
• Dispose of asbestos waste at approved facilities

NESHAP notification records are public documents. They are among the most concrete evidence available to former workers and their attorneys establishing that asbestos-containing materials were present at a specific facility at a specific time.

Asbestos-Containing Materials Documented in NESHAP Records

NESHAP abatement notification records filed with the WDNR in connection with renovation and demolition activities at We Energies and predecessor WEPCO facilities have reportedly identified the following categories of asbestos-containing materials:

• Pipe insulation — wrap and block insulation on steam, hot water, and process piping, reportedly containing chrysotile and/or amosite asbestos-containing materials from manufacturers including Johns-Manville and Owens-Illinois
• Boiler insulation — block and blanket insulation on boiler exteriors, reportedly containing high-temperature amosite and crocidolite asbestos-containing materials
• Turbine insulation — lagging and casing covers on steam turbines and associated equipment
• Valve and fitting insulation — pre-formed and field-applied asbestos-containing
