About Evergy Iatan Generation Station

The Evergy Iatan Generation Station in Weston, MO, is a power generation facility that began operations in 1980. The facility was equipped with major industrial systems typical of large power plants, including a Babcock & Wilcox boiler and steam system, General Electric turbine and generator equipment, Lodge-Cottrell particulate control systems, and was designed by Black & Veatch with construction by Daniel Construction. Asbestos-containing materials (ACMs) were extensively incorporated into power generation facilities like Evergy Iatan throughout the 20th century due to asbestos’s heat resistance, insulating properties, and durability. These materials were commonly used in insulation for pipes, boilers, and turbines (including pipe covering and calcium silicate insulation), electrical equipment components, and building materials such as floor tiles, roofing, and fireproofing products. Asbestos use declined in the late 20th century, but many older industrial plants — including the Evergy Iatan Generation Station — reportedly contained these materials well into the modern regulatory era. Disturbing these materials during routine maintenance, renovations, or demolition allegedly released microscopic asbestos fibers into the air.

Documented Asbestos Evidence

The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Missouri Department of Natural Resources (Missouri 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.

Official Missouri Department of Natural Resources (MDNR) records reportedly detail the presence and abatement of ACMs at the Evergy Iatan Generation Station. These records indicate multiple ACM categories requiring formal abatement projects. MDNR NESHAP (National Emission Standards for Hazardous Air Pollutants) abatement notifications show that several projects at the Evergy Iatan Generation Station and Iatan Generating Station reportedly involved ACM removal.

Who May Have Been Exposed at Evergy Iatan Generation Station

Workers from union halls — including Heat and Frost Insulators Local 1 (St. Louis, MO), Plumbers and Pipefitters UA Local 562 (St. Louis, MO), and Boilermakers Local 27 (St. Louis, MO) — reportedly performed contracted work at the Evergy Iatan Generation Station when ACMs may have been present. Insulators dispatched through Heat and Frost Insulators Local 1 who installed, repaired, or removed insulation may have directly handled asbestos-containing thermal system insulation, including pipe covering and calcium silicate insulation on pipes, boilers, and other high-temperature equipment. Pipefitters from Local 562 who cut, welded, and repaired pipes may have disturbed insulation jacketing those pipes or worked with gaskets and packing materials in valve and flange assemblies throughout the plant. Boilermakers from Local 27 involved in boiler construction, maintenance, and repair may have frequently encountered asbestos-containing refractory materials, insulation, and spray fireproofing products, often requiring removal and replacement of friable thermal system insulation. Electricians performing work on equipment may have been exposed to asbestos-containing electrical components, while maintenance workers performing repairs and minor renovations throughout the plant may have inadvertently disturbed friable ACMs. Construction and demolition workers involved in facility renovation and demolition projects — especially those involving roofing, flooring, and insulation systems — and roofers involved in documented roofing projects that removed tens of thousands of square feet of asbestos-containing roofing felt and flashing may have been directly exposed to friable asbestos fibers. Individuals who did not directly handle ACMs may have been exposed through secondary contamination if they worked in areas where asbestos fibers were airborne.

Critical Filing Deadline & Next Steps

Missouri law gives mesothelioma and asbestos-disease claimants 5 years from the date of medical diagnosis to file a personal-injury lawsuit (Mo. Rev. Stat. § 516.120). For wrongful-death claims after an asbestos-related death, the filing window is 3 years from the date of death (Mo. Rev. Stat. § 537.100). 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

  1. 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.
  2. Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
  3. 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.
  4. Speak with an asbestos attorney with Missouri 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

Workers who also labored at comparable regional industrial facilities including Granite City Steel/U.S. Steel (Granite City, IL), Laclede Steel (Alton, IL), Monsanto Chemical (Sauget, IL/St. Louis, MO), Shell Oil/Roxana Refinery (Wood River, IL), and Clark Refinery (Wood River, IL) may have encountered similar ACMs across multiple jobsites. Multi-site exposure histories are common among tradespeople in Missouri and the greater St. Louis metro area, reflecting the shared industrial corridor along the Mississippi River. This pattern of use was common across the industrial corridor shared by Missouri and Illinois along the Mississippi River.
