About Ames Municipal Power Plant | Ames, IA | City Of Ames (Iowa
The Ames Municipal Power Plant—also known as the Ames Electric Services generating facility—operated as a coal-fired steam generating station in Ames, Story County, Iowa. For more than a century, this facility generated electricity for the City of Ames, its residents, businesses, and Iowa State University.
Coal-fired steam generation is one of the most extreme industrial environments ever created. Before safer substitutes displaced asbestos-containing materials, virtually every major insulation product used in steam power applications reportedly contained asbestos in some form. Workers at the Ames plant may have encountered these materials on a routine, ongoing basis throughout their careers.
Many tradespeople who worked at the Ames Municipal Power Plant did not live in Iowa. Insulators, pipefitters, boilermakers, and electricians based in Iowa and Illinois regularly traveled to Iowa power plants for outage work, major overhauls, and new construction. If you are a Missouri or Illinois resident—or a surviving family member of one—your legal options may be broader than you realize, and the venues available to you in Missouri and Illinois may be significantly more favorable to asbestos plaintiffs than Iowa courts.
Iowa residents facing an asbestos-related diagnosis: your right to file exists today under current law—but pending 2026 legislation could fundamentally change the procedural landscape for every asbestos lawsuit filed after August 28, 2026. The single most important thing you can do after receiving a diagnosis is consult with a Iowa asbestos attorney immediately.
General Equipment at Ames Municipal Power Plant | Ames, IA | City Of Ames (Iowa
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 Iowa Department of Natural Resources (Iowa 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.
No Iowa DNR NESHAP abatement notifications have been identified for this facility in current public records. Per the framing above, absence of state-agency documentation should not be read as absence of asbestos — only as absence of a formal, regulated abatement event meeting reporting thresholds. Workers who recall encountering pipe insulation, block insulation, gaskets, or other asbestos-era construction materials at this facility may still have viable claims regardless of whether a state record exists.

Critical Filing Deadline & Next Steps
Iowa law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (Iowa Code § 614.1(2A)). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (Iowa Code § 614.1(2)). The two deadlines run on separate tracks — preserving one does not extend the other.
The personal-injury clock runs from diagnosis, not from exposure. Mesothelioma latency is typically 20 to 50 years, so workers exposed in the 1950s–1980s are being diagnosed today.
Practical first steps
- Document what you remember. Pay stubs, W-2s, union cards, photographs, coworker names, and dates of employment. The WorkChain widget on this page can save a copy you can email yourself.
- Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
- Identify household members. Spouses who laundered work clothing and children of plant workers are eligible for secondary-exposure claims when diagnosed with an asbestos-related disease.
- Speak with an asbestos attorney with Iowa experience. The first conversation is free and confidential. Asbestos trust-fund claims and civil claims run on different tracks — both can be pursued in parallel.
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
Power plant construction and maintenance in the Midwest was never purely a local operation. The Mississippi River industrial corridor—stretching from the Iowa border through Missouri and into southern Illinois—created a regional labor market where union tradespeople routinely crossed state lines for power plant work. Iowa’s power plants, including the Ames facility, drew significantly on this regional workforce.
Missouri union locals with documented histories of placing members at Midwest power plants include:
- Heat and Frost Insulators Local 1 (St. Louis), whose members may have performed insulation installation and removal at Iowa facilities including the Ames plant during major outages and construction phases
- UA Local 562 (Plumbers and Pipefitters, St. Louis), one of the largest pipefitting locals in the country, whose members were regularly dispatched to Midwest power plant projects
- Boilermakers Local 27 (St. Louis), whose members built, repaired, and overhauled steam boilers at facilities throughout the region, including Iowa municipal utilities
Illinois-based locals from the St. Louis metro area—including those from Madison County and St. Clair County—similarly supplied skilled tradespeople to Iowa power plant projects throughout the mid-twentieth century.
Missouri and Illinois tradespeople who worked at the Ames plant may have carried the same asbestos exposures home. The industrial corridor connecting St. Louis to Iowa City along the river and rail lines was also, for these workers, a potential corridor of asbestos exposure.
If you are a Missouri union member or retiree who traveled to Iowa power plants for work, you may have legal rights in Iowa courts—and those rights are time-sensitive in ways that are becoming more urgent as August 2026 approaches.
Comparable Midwest Facilities
Missouri and Illinois residents who may have encountered similar conditions at facilities along the Mississippi River corridor will recognize the industrial profile of the Ames plant:
- Labadie Energy Center (Franklin County, Missouri)—Ameren’s large coal-fired station on the Missouri River, where workers allege asbestos-containing insulation and gasket materials were extensively used
- Portage des Sioux Power Plant (St. Charles County, Missouri)—an Ameren facility where former workers and tradespeople have alleged exposure to asbestos-containing materials during construction and maintenance
- Granite City Steel (Madison County, Illinois)—where boilermakers, pipefitters, and insulators reportedly encountered asbestos-containing materials throughout the plant’s industrial operations
- Monsanto chemical complex (St. Louis, Missouri)—where workers and contractors may have encountered asbestos-containing insulation and fireproofing materials throughout decades of operations
The same manufacturers—, Armstrong, gaskets and packing—supplied asbestos-containing materials to power plants and heavy industrial facilities throughout this entire corridor. A Missouri or Illinois tradesperson who worked at multiple facilities during a career may have accumulated asbestos exposures at several sites, and the Ames Municipal Power Plant may be one of them.
