About Kansas City Power Light Hawthorn No 5 Unit Missouri Coal Plant Kansas City Missouri
What Was Hawthorn Unit 5?
Hawthorn Generating Station, located at 1800 East Front Street in Kansas City, Missouri, was one of the metropolitan area’s largest coal-fired power plants. Unit 5 was built during the post-World War II industrial expansion and operated for decades, serving Kansas City Power & Light customers across Jackson, Clay, Platte, and Cass counties in Missouri and northeastern Kansas. The facility’s boiler, turbine, and steam systems were heavily insulated with products manufactured by .
When Did Asbestos Exposure Occur?
The facility operated from the 1940s through the early 1980s and beyond. Significant asbestos exposure occurred during:
- Initial construction and equipment installation (1940s–1950s) — Workers from Heat and Frost Insulators Local 1 applied calcium silicate insulation asbestos block, pipe covering, and pipe covering and insulationproducts throughout the facility
- Regular maintenance and repair work (entire operational period) — Continuous exposure to gaskets and packingand Armstrong asbestos gaskets, asbestos rope packing, and insulation dust
- Scheduled maintenance outages and overhauls (every 12–24 months) — Intensive work inside asbestos-contaminated boiler drums and turbine enclosures
- Equipment replacement and system upgrades (ongoing) — Installation and removal of spray fireproofing spray coatings, pipe and block insulation, and gasket material refractories
- Facility decommissioning (1980s onward) — Asbestos removal under hazardous conditions
Who Hired Workers at Hawthorn?
Kansas City Power & Light employed some workers directly but contracted the majority of the work to specialty firms, including:
- Mechanical contractors specializing in boiler and turbine maintenance
- Insulation contractors certified by Heat and Frost Insulators Local 1 (St. Louis, MO)
- Industrial construction and maintenance contractors operating throughout Missouri
- Specialty trade firms in pipefitting (UA Local 562, St. Louis, MO), boilermaking (Boilermakers Local 27, St. Louis, MO), and electrical work (IBEW Local 124)
If your pay stub shows a contractor’s name rather than “Kansas City Power & Light,” you still worked alongside asbestos products every day. Whether you worked for a mechanical contractor, an insulation company, or through a trade union, you are entitled to pursue compensation for asbestos exposure in Missouri.
General Equipment at Kansas City Power Light Hawthorn No 5 Unit Missouri Coal Plant Kansas City Missouri
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 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.
The following 2 project notification(s) are documented with the Missouri Department of Natural Resources (NESHAP program) for Ameren Missouri in West Alton. These are public regulatory records.

Missouri Boiler and Pressure Vessel Registry — Equipment on File
The following boilers and pressure vessels were registered with the Missouri Department of Labor and Industrial Relations (DOLIR) for this facility. These are public records and have been introduced in asbestos exposure litigation to establish the presence of industrial heating and process equipment — and the contractors and inspectors who serviced it — at this site.

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
- 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 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.
