Why Former Power Plant Workers Are Filing Asbestos Lawsuits Now

If you worked at the Labadie Energy Center in Franklin County, the Portage des Sioux Power Plant in St. Charles County, the Rush Island Energy Center in Jefferson County, the Sioux Energy Center in St. Charles County, or any comparable facility along the Midwest industrial corridor — you may have been exposed to asbestos-containing materials decades ago. Those exposures felt routine at the time. Mesothelioma, asbestosis, and lung cancer can take 20 to 50 years to appear.

Aging power plant workers who believed they had left those hazards behind are now receiving diagnoses. As Ohio mesothelioma settlement specialists, we help former workers and families recover compensation through civil lawsuits and asbestos trust fund claims.

Ohio law gives most affected workers and their families five years from diagnosis to file — under Ohio Rev. Code § 2305.10. That window closes faster than most people expect, and it is now under active legislative pressure. ** Ohio residents who qualify may also file asbestos trust fund claims simultaneously with a civil lawsuit, potentially recovering compensation from multiple sources. An experienced asbestos attorney ohio can explain what claims are available and what the Ohio asbestos statute of limitations requires in your specific case.

How Asbestos Became Standard Equipment in Power Plants

The Industrial Case for Asbestos

Power generation facilities — including the Labadie Energy Center, Portage des Sioux Power Plant, Rush Island Energy Center, and Sioux Energy Center, all operated by Ameren UE — ran steam turbines, boilers, and piping systems at temperatures exceeding 1,000°F. From the 1940s through the mid-1970s, asbestos-containing materials were the engineering standard because they resisted extreme heat and fire, could be sprayed, woven, cast into cement, or formed into rigid shapes, cost little, lasted long, and outperformed any available alternative for industrial insulation.

These Missouri and Illinois facilities sat within the Mississippi River industrial corridor — a densely concentrated band of power plants, steel mills, refineries, and chemical plants stretching from St. Louis north through the Metro East region. Workers often moved between facilities throughout their careers, accumulating exposures at multiple sites operated by different employers using products from many of the same manufacturers.

What facility managers did not tell workers — and what product manufacturers actively suppressed — was that disturbing asbestos-containing materials during maintenance, repair, or renovation released fibers that caused fatal disease.

When Manufacturers Knew and What They Concealed

Asbestos use in power generation continued unchecked until the EPA and OSHA began restricting specific applications in the 1970s. By then, materials already installed remained in place for years or decades. Workers continued disturbing those materials during every maintenance outage and renovation. Product manufacturers had internal documents demonstrating hazard awareness going back decades before the public learned anything. Most workers received no warning labels and no respiratory protection.

The Facilities: What Was Built and When

Missouri Power Generation Facilities

Labadie Energy Center (Franklin County, MO) — Ameren UE’s major coal-fired plant was constructed and expanded during the peak decades of asbestos use. Workers at Labadie may have been exposed to asbestos-containing materials allegedly supplied by Johns-Manville, Owens-Illinois, Armstrong World Industries, Combustion Engineering, and other manufacturers. Members of Heat and Frost Insulators Local 1 (St. Louis) and Plumbers and Pipefitters UA Local 562 (St. Louis) reportedly performed insulation and pipefitting work at this facility throughout the plant’s construction and maintenance history.

Portage des Sioux Power Plant (St. Charles County, MO) — Also operated by Ameren UE, this facility served the Missouri grid through the same decades of intensive asbestos use. Insulators affiliated with Heat and Frost Insulators Local 1 and pipefitters with UA Local 562 may have been exposed to asbestos-containing materials during maintenance and renovation work at this plant. Boilermakers with Boilermakers Local 27 (St. Louis) may also have been exposed during boiler overhauls and repairs at this facility.

Rush Island Energy Center (Jefferson County, MO) — Ameren UE’s steam systems, turbines, and boilers at this facility may have contained extensive asbestos-containing insulation and gasket materials allegedly manufactured by Johns-Manville, Owens Corning, and Garlock Sealing Technologies. Workers from Heat and Frost Insulators Local 1 and Boilermakers Local 27 reportedly worked maintenance outages at this facility alongside Ameren UE’s own maintenance workforce.

Sioux Energy Center (St. Charles County, MO) — This facility’s mechanical systems may have incorporated asbestos-containing materials from Celotex Corporation, Eagle-Picher Industries, and Armstrong World Industries in insulation, gaskets, and building components. Like other Missouri River corridor plants, Sioux Energy Center may have received insulation and refractory work performed by members of Heat and Frost Insulators Local 1 and UA Local 562.

Ohio industrial facilities in the Same Region

Monsanto Chemical (Sauget, IL and St. Louis, MO) — Chemical manufacturing plants operated by Monsanto ran steam systems and boilers allegedly insulated with asbestos-containing pipe covering, gaskets, and building materials at facilities on both sides of the Mississippi River. Maintenance and operations workers may have been exposed to asbestos-containing materials across multiple job sites within these facilities. Monsanto’s St. Louis-area presence meant that workers from the same union locals who worked Missouri power plants may have also worked Monsanto maintenance shutdowns.

Illinois Industrial Facilities in the Mississippi River Corridor

Workers across the Ohio-Illinois Mississippi River industrial corridor faced comparable exposures at major industrial employers. Madison County and St. Clair County, Illinois — both significant asbestos litigation venues — sit directly across the river from Ohio, and many workers living in Ohio held union cards that sent them into these Illinois facilities throughout their careers.

Granite City Steel (Granite City, IL — Madison County) — This U.S. Steel facility may have contained asbestos-containing insulation on steam and process piping, boiler systems, and electrical equipment. Insulators on furnace systems and maintenance workers may have been exposed to asbestos-containing materials allegedly from Johns-Manville and Owens-Illinois. Madison County Circuit Court has historically been one of the most significant asbestos litigation venues in the United States, and cases involving Granite City Steel exposures have been filed there by former workers residing on both sides of the Mississippi.

Laclede Steel (Alton, IL — Madison County) — Steel manufacturing at this Madison County facility generated intense heat requiring extensive asbestos-containing insulation on boilers, furnaces, and piping systems. Workers may have been exposed during routine maintenance and major overhauls. Ohio residents who worked Laclede Steel maintenance may have viable claims in Madison County Circuit Court as well as Ohio courts.

Alton Box Board (Alton, IL — Madison County) — Paper and board manufacturing relied on steam generation and distribution systems allegedly insulated with asbestos-containing materials throughout the plant. This Madison County facility employed workers from across the St. Louis metro area.

Shell Oil Refinery and Roxana Refinery (Wood River, IL — Madison County) — Petroleum refining required extensive steam systems and process piping allegedly insulated with materials from Johns-Manville, Owens Corning, and Combustion Engineering. These Wood River facilities were part of the densely industrialized Madison County riverfront that generated substantial asbestos exposure claims.

Clark Refinery (Wood River, IL — Madison County) — This facility’s steam distribution and process systems may have contained asbestos-containing insulation and gasket materials comparable to those used at other regional refineries. Workers affiliated with St. Louis-area union locals may have performed insulation and pipefitting work at this facility alongside Illinois-based tradespeople.

The Granite City and Metro East Industrial Complex — The concentration of steel, refining, chemical, and power generation facilities along the Illinois side of the Mississippi River in Madison and St. Clair Counties created overlapping exposure scenarios for workers who moved between facilities throughout their careers. A pipefitter or insulator working out of St. Louis in the 1960s might work Labadie Energy Center one month and Granite City Steel or the Wood River refineries the next. The cumulative exposure picture matters — and it matters in court.

⚠️ The 2026 Legislative Threat: Understanding Ohio’s Asbestos Statute of Limitations

Ohio’s **2-year statute of limitations for asbestos personal injury claims under Ohio Rev. Code § 2305.10 remains in effect — but that protection faces a concrete legislative threat with a specific date attached to it.

Asbestos-Containing Materials Allegedly Present at These Facilities

Workers at the Labadie Energy Center, Portage des Sioux Power Plant, Rush Island Energy Center, Sioux Energy Center, and comparable regional facilities in Missouri and along the Illinois side of the Mississippi River corridor may have been exposed to asbestos-containing materials in the following forms, based on documented patterns of asbestos use at power generation and industrial facilities during the same period:

Pipe Insulation and Block Insulation

High-temperature pipe covering — commonly manufactured as calcium silicate block or magnesia block insulation — was allegedly produced by Johns-Manville, Owens-Illinois, Combustion Engineering, and Armstrong World Industries for application on steam lines, feedwater lines, and process piping throughout these facilities. Insulators applied this material by hand, cutting blocks and wrapping sections around hot pipe — a process that generated heavy concentrations of airborne fiber. Pipefitters and maintenance mechanics who worked alongside insulators during these operations may have been exposed even though insulation installation was not their primary trade.

Boiler Insulation and Refractory Materials

Power plant boilers operated at extreme temperatures requiring asbestos-containing refractory cement, castable insulation, and block insulation on boiler exteriors, breechings, and associated ductwork. Boilermakers who opened, repaired, and relined these units during maintenance outages may have been exposed to asbestos-containing materials from the existing installation as well
