About Port Washington Power Station | Port
Port Washington Generating Station was a coal-fired power plant operated by Wisconsin Electric Power Company in Ozaukee County, Wisconsin, with seven generating units that operated from 1935 to the 2000s. The facility included Units 1–4 (coal-fired, Arch-type boilers manufactured by Alstom/Fw), Unit 5 (coal-fired, Dsaa-type boiler), and Unit 6 (a 19.6 MW oil-fired gas turbine unit commissioned in 1968). The plant operated continuously for over 70 years, with most units retired by 2002. The facility’s boiler systems operated at high steam pressures (ranging from 1230 to 1450 PSI) and temperatures (825°F to 950°F), requiring extensive thermal insulation systems and refractory materials throughout the power generation and steam distribution infrastructure.General Equipment at Port Washington Power Station | Port
The equipment below represents the systems and infrastructure documented or typically present at this facility during the era when asbestos-containing materials were specified in industrial construction. This is general facility-equipment reference — not a legal attribution of any specific product, manufacturer, or exposure event to this facility. Material-category and manufacturer information is addressed in the AsbestosIndex Product Crosswalk linked under the records table below.
Documented Asbestos Evidence
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Wisconsin Department of Natural Resources (Wisconsin DNR) was notified under federal NESHAP rules, the work was logged, and the asbestos-containing material was confirmed and removed under regulated conditions. These are not allegations or estimates — they are paper records tying documented asbestos-containing material to this specific site.

Who May Have Been Exposed at Port Washington Power Station | Port
Insulators — particularly members of Heat and Frost Insulators Local 1 — carried among the highest documented mesothelioma and asbestos-related lung cancer risks at the facility due to direct contact with asbestos-containing calcium silicate pipe insulation and other thermal insulation products. Pipefitters and steam fitters installed, maintained, and replaced heavily insulated pipe systems and handled asbestos-containing gaskets, packing materials, and joint compounds during routine maintenance and emergency repairs. Boilermakers fabricated, installed, and repaired boiler components, working directly with boiler block insulation, refractory materials, and asbestos-containing gaskets, with particular exposure risk during scheduled outages when boilers were opened for repair. Electricians, instrument technicians, millwrights, equipment mechanics, and general maintenance personnel experienced both direct and bystander exposure to asbestos-containing materials throughout the facility. Demolition and abatement workers involved in decommissioning and removal of insulated pipe systems, boiler insulation, and other asbestos-containing components during plant closure experienced high-intensity exposure without adequate respiratory protection.⚠️ 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:
- 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.
- 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.
- 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.
- 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.
- 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
Union workers in the insulation, pipefitting, boilermaking, and electrical trades routinely followed work across state lines through dispatch systems operated by regional locals. A journeyman insulator from Heat and Frost Insulators Local 1 in St. Louis might spend months at Labadie, travel to Port Washington for a scheduled outage, then return to Portage des Sioux. Union workers dispatched from UA Local 562 (United Association of Plumbers and Pipefitters) throughout Wisconsin, Illinois, and the surrounding region may have been dispatched to Port Washington as part of major industrial maintenance projects throughout the Mississippi River corridor. Boilermakers Local 27 (St. Louis, Missouri) represents boilermakers throughout Wisconsin and the surrounding region, with members potentially dispatched to Port Washington and other regional power facilities.Data Sources
