1. Facility Overview and Operational History
What Is the Hawthorn Generating Station?
The Hawthorn Generating Station is a coal-fired electric power plant located along the Missouri River in the Kansas City metropolitan area. Kansas City Power & Light (KCPL) — now operating as Evergy following a 2018 merger with Great Plains Energy and Westar Energy — has operated the facility since the early-to-mid twentieth century.
Construction and Asbestos Use Across Decades
Hawthorn was built and expanded during the period when industrial facilities were routinely constructed and maintained using asbestos-containing materials from manufacturers including Johns-Manville, Owens-Illinois, Garlock Sealing Technologies, Eagle-Picher, and W.R. Grace. Those materials were reportedly incorporated into virtually every major system in the plant. Engineers and purchasing departments of that era specified asbestos-containing materials as the standard choice for:
- Thermal insulation products, including Kaylo, Thermobestos, and Aircell brands
- Fireproofing systems, including Monokote applications
- Gaskets and seals manufactured by Garlock Sealing Technologies
- Packing materials
- Refractory cements and products
- Electrical components from manufacturers including Crane Co.
Major Expansions and Modernization Projects
Hawthorn underwent multiple unit additions and expansions over its operational lifespan. Each successive generation of turbines, boilers, piping systems, and electrical infrastructure brought additional installations of asbestos-containing materials manufactured by Johns-Manville, Owens-Illinois, Armstrong World Industries, and Combustion Engineering. Workers faced recurring exposure risk each time those materials were disturbed during maintenance and repairs.
Scheduled maintenance outages at large generating stations are precisely the conditions under which asbestos fibers become airborne and reach workers’ lungs.
The 2019 Explosion and Subsequent Remediation
Following the 2019 explosion and fire at Hawthorn Unit 5 — which caused structural damage and claimed contract workers’ lives — the facility underwent extensive remediation and reconstruction. Abatement activities associated with that incident and the subsequent rebuilding effort reportedly involved handling legacy asbestos-containing materials, including insulation products characteristic of mid-twentieth-century power plant construction, allegedly manufactured by Johns-Manville, Owens-Corning, and Armstrong World Industries.
Corporate Liability and Operator Responsibility
Kansas City Power & Light and its predecessor and successor entities have been named as defendants or identified as sites of exposure in asbestos-related personal injury litigation filed by former workers and their families. The manufacturers — Johns-Manville, Owens-Illinois, Garlock Sealing Technologies, Eagle-Picher, Crane Co., Combustion Engineering, Armstrong World Industries, W.R. Grace, Georgia-Pacific, Celotex, and others — produced the asbestos-containing materials at issue.
KCPL was not an asbestos manufacturer. But as the facility operator responsible for specifying, purchasing, and directing the installation of those materials, it falls within the scope of responsibility that experienced asbestos litigators examine when building a case for injured workers and their families.
2. Why Asbestos-Containing Materials Were Used at Power Plants
Coal-fired power plants became among the most asbestos-intensive industrial environments in American history. Understanding why explains where exposure occurred and why it was so severe.
The Physics of Power Generation Create Extreme Thermal Demands
Coal-fired power plants operate under conditions that demand constant management of extreme heat and pressure:
- Steam boilers operate at temperatures exceeding 1,000 degrees Fahrenheit
- Pressure systems operate at pressures measured in hundreds of pounds per square inch
- Turbines spin at thousands of revolutions per minute
- High-pressure steam piping carries superheated steam from boiler to turbine to condenser — miles of pipe under constant thermal stress
Every inch of that piping, every valve, every flange, every boiler wall, every turbine casing, and every heat exchanger was, in the engineering practice of the mid-twentieth century, a location where asbestos-containing insulation products from Johns-Manville (including Kaylo and Thermobestos brands), Owens-Illinois, Armstrong World Industries, and Celotex were the technically superior and economically standard choice.
Why Asbestos Was Specified — Superior Material Properties
Asbestos offered a combination of properties that no affordable synthetic alternative could match until the 1970s and 1980s:
- Heat resistance — chrysotile and amphibole asbestos fibers retain structural integrity at temperatures that destroy organic materials
- Low thermal conductivity — asbestos-containing pipe insulation reduced heat loss and improved plant efficiency
- Chemical resistance — asbestos did not degrade when exposed to the acids, alkalis, and steam condensate present in power plant environments
- Mechanical durability — asbestos-containing gaskets and packing materials from Garlock Sealing Technologies and others maintained sealing properties under repeated thermal cycling
- Fire resistance — asbestos-containing fireproofing, including Monokote formulations, protected structural steel
- Low cost — asbestos was inexpensive relative to its performance characteristics for most of the twentieth century
Industry Standards Specified Asbestos-Containing Materials
ASME, ASTM, and various federal and state agencies specified asbestos-containing materials in their codes and standards for power plant construction throughout most of the twentieth century. Kansas City Power & Light was not acting outside industry norms when it purchased products from Johns-Manville, Owens-Illinois, Garlock Sealing Technologies, and other major manufacturers — it followed the consensus guidance of the engineering profession.
That institutional normalization does not eliminate legal liability. Decades of litigation have established that manufacturers including Johns-Manville, Owens-Illinois, Armstrong World Industries, Crane Co., Combustion Engineering, Eagle-Picher, W.R. Grace, Georgia-Pacific, Celotex, and Garlock Sealing Technologies knew of the health hazards of asbestos fiber inhalation far earlier than they disclosed to workers, purchasers, or regulators. The failure to warn is the central theory of liability in asbestos personal injury claims against these manufacturers.
3. Timeline of Asbestos-Containing Materials at Hawthorn
Construction and Early Operational Period (Pre-1975)
Based on the documented history of asbestos use in American industrial construction, asbestos-containing materials manufactured by Johns-Manville, Owens-Illinois, Armstrong World Industries, and other suppliers were reportedly incorporated into the Hawthorn Generating Station from original construction through at least the mid-1970s — and in many cases may have remained in place in undisturbed areas of the plant long after that date.
During initial construction and any subsequent unit additions prior to approximately 1975, workers including members of Heat and Frost Insulators Local 1 and Local 27, Plumbers and Pipefitters UA Local 562 and Local 268, and other trades would reportedly have worked with or around asbestos-containing materials from Johns-Manville (Kaylo, Thermobestos), Owens-Illinois, and Garlock Sealing Technologies as a matter of routine.
The 1970s Transition Period: Regulatory Change and Continued Asbestos Use
The regulatory environment shifted during the early 1970s:
- 1970: The U.S. Environmental Protection Agency began regulating certain asbestos uses under the Clean Air Act
- 1971: OSHA issued its first permissible exposure limit for asbestos
- Early 1980s: Regulatory restrictions on asbestos in industrial insulation phased in gradually, though manufacturers continued selling existing inventory
Many asbestos-containing products from Johns-Manville, Owens-Illinois, Armstrong World Industries, and Celotex remained legally available and in widespread use through the early 1980s. During this transition period, Hawthorn workers may have faced exposure from two directions simultaneously:
- Newly installed materials still containing asbestos
- Legacy asbestos-containing materials from earlier decades, disturbed during ongoing maintenance and repair operations
Long-Term Maintenance and Scheduled Outage Exposure (1970s–1990s and Beyond)
Maintenance workers face a different asbestos exposure profile than construction workers — and in many ways a more dangerous one. A pipefitter replacing valve packing year after year, an insulator removing and re-lagging boilers during scheduled outages, a boilermaker cutting into pipe sections during a turnaround — each of those workers repeatedly disturbed existing asbestos-containing materials over years and decades of employment.
At Hawthorn, as at virtually every coal-fired power plant built before the 1980s, maintenance and repair operations reportedly required recurring disturbance of:
- Asbestos-containing pipe insulation from Johns-Manville (Kaylo, Thermobestos, Aircell brands)
- Boiler insulation products from multiple manufacturers
- Turbine insulation
- Gaskets manufactured by Garlock Sealing Technologies
- Packing materials from Garlock and others
- Refractory cements
- Electrical components from Crane Co.
Workers employed at the facility for extended periods — common among skilled tradespeople at unionized utility plants — may have accumulated significant cumulative exposure through this pattern of repeated, short-duration disturbances over a full career.
4. High-Risk Occupations at Hawthorn
Not every worker at Hawthorn faced the same level of asbestos exposure risk. Certain trades and job classifications were routinely positioned closest to asbestos-containing materials during the operations most likely to release airborne fibers.
