Wisconsin Mesothelioma Lawyer: Port Washington Power Plant Asbestos Exposure

Port Washington, Wisconsin | Wisconsin Electric Power Company

⚠️ CRITICAL WISCONSIN FILING DEADLINE WARNING
Wisconsin law imposes a strict three-year statute of limitations under Wis. Stat. § 893.54. If you or a family member has been diagnosed with mesothelioma, asbestosis, or another asbestos-related disease, that three-year clock begins running from the date of diagnosis — not the date of exposure. Miss this deadline and you permanently forfeit your right to compensation in Wisconsin civil court. No exceptions. No extensions.
Asbestos bankruptcy trust fund claims can be filed simultaneously with your civil lawsuit in Wisconsin, and most trusts do not impose rigid filing deadlines — but trust assets are finite and actively depleting. Every month you wait is a month closer to reduced recoveries.
Do not wait. Call our Wisconsin asbestos attorney team today.

If You Worked at Port Washington Power Plant

The Port Washington Power Plant, operated by Wisconsin Electric Power Company (now We Energies) along Lake Michigan’s western shore, was one of the Upper Midwest’s largest coal-fired steam generating stations. For decades it powered hundreds of thousands of Wisconsin homes and businesses. Inside its turbine halls and boiler rooms, workers reportedly encountered asbestos-containing insulation, pipe covering, and thermal products throughout construction, expansion, and maintenance cycles spanning multiple decades.

Former workers, their families, and members of Boilermakers Local 107, IBEW Local 494, Asbestos Workers Local 19, and Pipefitters Local 601 who spent careers at this facility may have been exposed to asbestos-containing materials — including Kaylo, Thermobestos, Aircell, and Monokote from manufacturers including Johns-Manville, Owens-Illinois, and Combustion Engineering. Decades later, some of those workers — and family members who laundered contaminated work clothes — are receiving diagnoses of mesothelioma, asbestosis, lung cancer, and other asbestos-related diseases.

If you or a loved one worked at the Port Washington Power Plant and have been diagnosed with an asbestos-related illness, Wisconsin’s three-year filing deadline under Wis. Stat. § 893.54 is already running from your diagnosis date. Legal remedies exist — but they disappear permanently once that deadline passes. This page explains what happened at this facility, who was at risk, what diseases result from asbestos exposure, and how to pursue a Wisconsin asbestos lawsuit before it is too late.

The Port Washington Power Plant: Facility Background

Location and Operations

The Port Washington Power Plant sits along Lake Michigan in Port Washington, Wisconsin — approximately 30 miles north of Milwaukee in Ozaukee County. Wisconsin Electric Power Company, now We Energies, operated the facility from the early twentieth century forward, building it into one of Wisconsin’s largest steam-electric generating stations and a critical node in the state’s energy infrastructure.

Construction and Expansion History

The plant expanded incrementally across several decades:

Multiple generating units added throughout the twentieth century
Massive boiler installations requiring extensive thermal insulation
Miles of high-pressure steam and feedwater piping
Turbines, condensers, and feedwater heaters requiring thermal protection
Coal-fired operations at extreme temperatures and pressures demanding constant maintenance

Each expansion required thousands of feet of asbestos-containing materials — standard industry practice at the time, now understood to be lethal. Workers from Milwaukee, Ozaukee, and Washington counties, as well as tradespeople dispatched through Milwaukee-area union halls, are among those who may have been exposed during these construction and expansion phases.

Why Power Plants Used Asbestos-Containing Materials

From roughly the 1930s through the mid-1970s — and in some cases into the early 1980s — asbestos-containing products were the insulation material of choice for high-temperature industrial applications. Resistance to heat, fire, and chemical degradation made asbestos-containing materials standard across American power plants, including multiple Wisconsin Electric facilities serving southeastern Wisconsin. OSHA and EPA regulatory pressure, combined with evolving public health science, eventually drove asbestos-containing products out of new construction — but not before generations of Wisconsin power plant workers sustained repeated exposures at Port Washington and sister facilities throughout the state.

Asbestos-Containing Materials Reportedly Present at Port Washington

Product Types

Asbestos-containing materials were reportedly present in virtually every thermal application at Port Washington:

Block insulation — products such as Kaylo and Thermobestos — on boilers, furnace walls, and high-temperature surfaces
Pipe covering on steam, condensate, and feedwater lines
Boiler gaskets and rope packing reportedly containing chrysotile asbestos
Turbine and valve insulation — products such as Aircell
Insulating cement applied as finishing coats over block and pipe sections
Asbestos cloth and tape used in lagging and patching applications
Insulating board — products such as Gold Bond — in walls, ceilings, and equipment enclosures
Refractory materials in boiler furnaces and pressure vessels

Manufacturers of Allegedly Supplied Asbestos-Containing Products

Johns-Manville

Johns-Manville — also known as J-M or Manville Corporation — was one of the nation’s largest producers of asbestos-containing insulation products. Products allegedly supplied to facilities like Port Washington include pipe covering, block insulation for boiler applications, insulating cement, asbestos cloth, and thermal protective products for steam systems.

Johns-Manville asbestos-containing products were distributed extensively to Wisconsin industrial facilities — reportedly including Allen-Bradley in Milwaukee, Allis-Chalmers in West Allis, and Falk Corporation in Milwaukee, as well as to Wisconsin Electric’s power generation facilities. Internal company documents produced in litigation showed that Johns-Manville executives knew of asbestos health hazards decades before disclosing those risks to the workers and Wisconsin tradespeople who installed their products.

Owens-Illinois (Kaylo)

Owens-Illinois manufactured Kaylo, a calcium silicate pipe and block insulation product containing asbestos, and marketed it aggressively to power utilities and industrial facilities throughout Wisconsin and the Upper Midwest. Asbestos-containing Kaylo insulation may have been applied to steam lines, boiler surfaces, high-temperature systems, and feedwater heater installations at Port Washington. Court records from asbestos litigation document widespread distribution of Owens-Illinois Kaylo to Wisconsin power plants and heavy industrial facilities during the relevant period.

Combustion Engineering

Combustion Engineering manufactured industrial boilers and steam-generating equipment and supplied and specified insulation systems, refractory materials, and block insulation for its boiler products. Where Combustion Engineering boilers were installed at Port Washington, asbestos-containing block insulation may have been specified as standard, with products potentially including materials marketed as Cranite and Superex.

Armstrong World Industries

Armstrong World Industries manufactured pipe covering and block insulation products containing asbestos distributed to power utilities and industrial customers throughout Wisconsin. Asbestos-containing Armstrong products may have been installed at Port Washington during expansion and maintenance phases.

W.R. Grace

W.R. Grace produced asbestos-containing thermal insulation products supplied to industrial and utility customers throughout Wisconsin and the broader Midwest region.

Georgia-Pacific

Georgia-Pacific manufactured asbestos-containing insulating products distributed to industrial facilities across Wisconsin and the region during this era.

Other Potential Suppliers

Additional manufacturers whose asbestos-containing materials were common in Wisconsin’s utility and heavy industrial sector during this period include:

Celotex Corporation — insulating board and block insulation
Crane Co. — valve and equipment insulation systems
Eagle-Picher Industries — pipe covering and thermal products
Garlock Sealing Technologies — gasket and packing materials containing asbestos

Who Was at Risk for Asbestos Exposure at Port Washington?

Asbestos exposure at Port Washington was not confined to a single trade. Multiple crafts worked simultaneously in shared spaces where asbestos-containing insulation materials reportedly generated airborne dust during installation, disturbance, and removal. Many of these workers were dispatched through Milwaukee-area union halls and lived in communities throughout southeastern Wisconsin, including Milwaukee, Ozaukee, Washington, and Waukesha counties.

Insulators — Asbestos Workers Local 19

No trade worked more directly with asbestos-containing thermal products than insulators. Members of Asbestos Workers Local 19 — the Milwaukee-based local representing insulation workers throughout the region — performed installation of pipe covering on steam and feedwater lines, application of block insulation to boiler surfaces, mixing and application of insulating cement, and cutting, shaping, and fitting of asbestos-containing calcium silicate blocks and pipe sections. This work may have exposed insulators to airborne asbestos fibers in significant quantities.

Insulators dispatched through Asbestos Workers Local 19 to Port Washington are among the most heavily represented occupations in Wisconsin mesothelioma litigation. Local 19 members who also rotated through Allis-Chalmers in West Allis or Falk Corporation in Milwaukee may have sustained cumulative exposures across multiple facilities — a factor that directly increases the value of your legal claim.

If you are a former Asbestos Workers Local 19 member diagnosed with mesothelioma or asbestosis, Wisconsin’s three-year statute of limitations under Wis. Stat. § 893.54 is running from your diagnosis date. Call our office today.

Pipefitters and Steamfitters — Pipefitters Local 601

Members of Pipefitters Local 601 — the Milwaukee-based local representing pipefitters and steamfitters throughout southeastern Wisconsin — worked alongside insulators and performed installation and modification of high-pressure steam and feedwater piping, repair and maintenance of piping systems insulated with asbestos-containing materials, removal and re-application of Kaylo, Thermobestos, and other insulation during repair operations, and handling of asbestos-containing gaskets and valve packing, including materials from Garlock Sealing Technologies.

Pipefitters who disturbed aged asbestos-containing insulation during maintenance — rather than installing it fresh — may have faced some of the highest fiber concentrations of any trade on site. Many Local 601 members also worked at Milwaukee-area industrial facilities such as A.O. Smith and Allen-Bradley, compounding their lifetime exposure burden.

Former Pipefitters Local 601 members diagnosed with an asbestos-related disease must act within three years of diagnosis under Wis. Stat. § 893.54 or permanently lose the right to sue in Wisconsin civil court. Call our asbestos attorney Wisconsin office today.

Boilermakers — Boilermakers Local 107

Members of Boilermakers Local 107 — representing boilermakers throughout the Milwaukee area and Wisconsin — handled construction, maintenance, repair, and periodic overhaul of Port Washington’s boilers. Their work included assembly of steam boilers, entry into boiler furnaces and pressure vessels, and repair and renovation involving asbestos-containing refractory and block insulation, including products such as Cranite and Superex, in confined spaces during plant overhauls.

Asbestos dust concentrations in confined boiler spaces during overhaul periods may have reached acutely dangerous levels. Boilermakers Local 107 members are disproportionately represented among mesothelioma victims in Wisconsin power plant litigation. Local 107 members who also worked at Allis-Chalmers in West Allis or other Wisconsin heavy industrial sites may have sustained cumulative exposures that significantly strengthen their legal claims.

Boilermakers Local 107 members diagnosed with mesothelioma, asbestosis, or lung cancer: your three-year filing deadline under Wis. Stat. § 893.54 runs from your diagnosis date — not from your last day of work. Contact a mesothelioma lawyer Wisconsin today.

Electricians — IBEW Local 494

Members of IBEW Local 494 — the Milwaukee-based local representing electricians throughout southeastern Wisconsin — worked throughout Port Washington’s generating units in close proximity to workers actively cutting, fitting, and applying asbestos-containing insulation. Electricians did not typically install insulation themselves, but bystander exposure to airborne asbestos fibers generated by nearby trades is well-documented in asbestos litigation and may have resulted in significant cumulative exposure over a career.

Millwrights and Laborers

Millwrights and general laborers performed maintenance, equipment handling, and cleanup work throughout the plant. This work may have brought them into direct contact with asbestos-containing debris, disturbed insulation, and accumulated dust in areas where asbestos-containing materials had been applied or removed.
