About Alma Station | Alma, WI

Alma Station is a coal-fired power plant in Buffalo County, Wisconsin, operated by Dairyland Power Cooperative. The plant has generated electricity since the mid-twentieth century. Like most coal-fired generating facilities built before 1980, Alma Station reportedly relied on thermal insulation, gasket materials, and fireproofing products that may have contained asbestos-containing materials throughout its construction and early decades of operation.

Coal-fired power plants generate extreme heat. Turbines, boilers, steam lines, condensers, and feedwater systems all require thermal insulation capable of withstanding temperatures that destroy ordinary materials. From roughly 1930 through the late 1970s, asbestos-containing materials were the industry standard solution. Asbestos-containing materials were used for pipe and equipment insulation — applied to steam lines, turbine casings, feedwater heaters, and boiler surfaces; gaskets and packing — used at valve joints, pump seals, and flange connections throughout high-pressure systems; refractory and fireproofing materials — sprayed or troweled onto structural steel and boiler room walls; floor tile and adhesives — installed in control rooms, maintenance shops, and administrative areas; and electrical insulation — wrapped around wiring and used in switchgear components.

The facility includes five generating units: Alma 1 and 2 (1947, 20 MW each), Alma 3 (1951, 20 MW), Alma 4 (1957, 55 MW), and Alma 5 (1959, 84 MW), all coal-fired with front-type boilers operating at steam pressures ranging from 850 PSI at 900°F to 1450 PSI at 1000°F.

Who May Have Been Exposed at Alma Station | Alma, WI

Workers who spent time at Alma Station — operators, maintenance crews, pipefitters, boilermakers, insulators, and contractors — may have been exposed to asbestos-containing materials during routine work and during repair or renovation projects.

Insulators cut and shaped pipe insulation daily. Every cut released fiber clouds. Heat and Frost Insulators Local 1 — representing insulation workers throughout the St. Louis metropolitan area — members were reportedly dispatched to power plant projects throughout the region, including facilities outside Missouri. Boilermakers worked inside boiler systems during outages, surrounded by deteriorating insulation and refractory material. Members of Boilermakers Local 27, based in St. Louis, have historically been dispatched to regional utility outages. Pipefitters and steamfitters removed old gaskets, scraped joint compound, and replaced packing material — all tasks that allegedly disturbed asbestos-containing materials at close range. UA Local 562 dispatched members to power plant construction and maintenance projects throughout the region. Maintenance mechanics repaired pumps, valves, and turbines. Gasket removal and replacement was routine maintenance work that may have disturbed asbestos-containing materials. Electricians worked in cable trays and switchgear rooms where asbestos-containing electrical insulation was allegedly present. Control room operators worked in buildings where asbestos-containing floor tile, ceiling tile, and wall materials may have been installed. Outside contractors — who often performed the most intensive insulation work — moved between facilities and carried accumulated fiber burden from multiple sites. Bystander exposure was common. Workers in adjacent trades who never personally handled asbestos-containing materials still breathed fibers released by workers who did.

⚠️ Critical Filing Deadline

Wisconsin law gives mesothelioma and asbestos-disease victims 3 years from the date of medical diagnosis to file a personal injury lawsuit (Wis. Stat. § 893.54). For wrongful death claims after an asbestos-related death, the filing window is 3 years from the date of death (Wis. Stat. § 893.54). Miss either deadline by a single day and the right to file is permanently gone. No exceptions, no extensions.

About the two deadlines: Wisconsin keeps the personal-injury clock (Wis. Stat. § 893.54) and the wrongful-death clock (Wis. Stat. § 893.54) on separate tracks. The 3 years personal-injury deadline runs from the date of diagnosis and applies to the diagnosed person's own claim while they are alive. The 3 years wrongful-death deadline runs from the date of death and applies to surviving family members. The two are independent — preserving one does not extend the other, and an asbestos attorney with experience in Wisconsin can keep both options open as the situation evolves.

The personal-injury clock runs from the date of medical diagnosis — not from the date of asbestos exposure. Mesothelioma can take 20 to 50 years to develop after exposure. Many workers are only now receiving diagnoses from exposures that occurred decades ago.

Treat the 3 years deadline as a hard outer limit, not a planning horizon.

⚠️ Why You Must Act Now

Wisconsin's filing window may sound like ample time. It is not. Every month that passes after a mesothelioma diagnosis is a month in which your case gets harder to build and your options narrow.

Witnesses Become Harder to Reach

The tradespeople who worked alongside mesothelioma victims at facilities of this era are now in their 70s and 80s. Witnesses from many years ago are harder and harder to contact by the day — coworkers who can testify about which asbestos-containing materials were used, who supplied them, and how the work was done are increasingly difficult to locate. Once first-hand testimony becomes unavailable, that record is gone.

Records Disappear

Employment records, union records, purchasing records, and product invoices that document exactly which asbestos-containing materials were used at this facility are being lost every year. Plants close. Corporate owners change. Storage facilities are cleared. Records that existed five years ago may not exist today.

Mesothelioma Cases Are Complex to Build

Identifying every responsible manufacturer and every jobsite across a tradesperson's career requires intensive investigation by experienced toxic-tort counsel. A case against the manufacturers who supplied asbestos-containing materials to this facility may involve dozens of defendants. That investigation takes time that waiting families do not have.

Asbestos Trust Fund Claims Run on a Separate Track

More than 60 asbestos bankruptcy trusts exist to compensate victims whose exposures came from manufacturers that have since gone bankrupt — including the Manville Personal Injury Settlement Trust, established after the 1982 Johns-Manville bankruptcy. Each trust has its own claim forms, exposure criteria, documentation requirements, and processing timelines. Pursuing trust-fund compensation in parallel with a lawsuit takes months. The trust-fund process should start now, not after you decide whether to file suit.

What To Do Next

If you or a family member has been diagnosed with mesothelioma, asbestosis, or another asbestos-related disease — and you worked at this facility, lived with someone who did, or worked at neighboring industrial sites in the corridor — the practical next steps are:

  1. Speak with an asbestos attorney with experience in Wisconsin. The first conversation is free, confidential, and creates no obligation. An experienced attorney will help you understand which trust-fund claims may apply, which civil claims are viable, and what documentation you should start gathering.
  2. Gather what you can about your work history. Pay stubs, W-2s, union cards, photographs, names of coworkers, and dates of employment all become important evidence. The WorkChain widget on this page can help you organize and email yourself a copy of your facility list.
  3. Preserve your medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests all become part of the legal record. Ask your treating physicians for full copies of everything in your chart.
  4. Identify household members who may also have been exposed. Spouses who laundered work clothing and children who hugged a parent returning from the plant are eligible for secondary-exposure claims when they have been diagnosed with an asbestos-related disease.
  5. Act before the filing deadline runs. Wisconsin's statute of limitations is a hard outer limit. Even if you are still in the middle of treatment decisions, beginning the legal process early preserves your options.

Asbestos-Related Diseases

Asbestos fiber exposure can cause several specific diseases that typically appear decades after the original exposure. The latency period — the gap between exposure and diagnosis — usually runs 20 to 50 years. That's why workers exposed in the 1960s, 1970s, and 1980s are receiving diagnoses today.

Mesothelioma

A rare, aggressive cancer that affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal), or heart (pericardial). Mesothelioma is almost exclusively caused by asbestos exposure, which is why a mesothelioma diagnosis often points directly to historical workplace exposure. Average latency from first exposure to diagnosis is 30-50 years.

Asbestosis

A chronic, non-cancerous scarring of lung tissue caused by inhaled asbestos fibers. Asbestosis causes progressive shortness of breath, persistent cough, and reduced lung function. It does not improve with treatment, and it is a recognized basis for compensation under most trust schedules and civil claims.

Lung Cancer

Asbestos exposure significantly increases the risk of lung cancer, particularly when combined with a history of smoking. Asbestos-related lung cancer is compensable under the same trust schedules and civil claim avenues as mesothelioma.

Other Recognized Diseases

Pleural plaques, pleural thickening, laryngeal cancer, ovarian cancer, and certain gastrointestinal cancers are also recognized as asbestos-related under various trust schedules and case-law authorities, though eligibility and proof requirements vary by claim type.

If you have any of these diagnoses and you worked at this facility, lived with someone who did, or were exposed in any documented capacity, you may have a claim worth pursuing. Speak with an attorney before assuming you don't qualify.

Cross-State & Regional Corridor Workers

Many workers who may have been exposed at Alma Station are Missouri and Illinois residents who traveled to Wisconsin job sites through union dispatch or contractor assignments, then returned home to communities along the Mississippi River industrial corridor. The same asbestos-containing products reportedly used at Alma Station were reportedly used at facilities throughout the Mississippi River industrial corridor — at Ameren’s Labadie Energy Center in Franklin County, at Dairyland’s peer facilities, at AmerenUE’s Portage des Sioux plant in St. Charles County, and at heavy industrial facilities including Granite City Steel across the river in Madison County, Illinois. Workers dispatched from Missouri union halls to Wisconsin job sites carried the same trades knowledge and faced the same fiber hazards they knew from home. Local 1 members who traveled to Wisconsin job sites may have encountered the same asbestos-containing insulation products they allegedly handled at Labadie and Portage des Sioux. Local 27 members who performed outage work at Alma Station may have been exposed to asbestos-containing materials during those assignments. Members dispatched through Local 562 to Wisconsin utilities may have been exposed to asbestos-containing materials during those assignments. A contractor who worked at Alma Station in Wisconsin may also have worked at Labadie in Missouri, at Portage des Sioux in Missouri, or at Granite City Steel in Illinois. Each of those alleged exposures is legally cognizable and may support separate claims.
