What Is AES Petersburg Generating Station?

The AES Petersburg Generating Station sits in Pike County near Petersburg, Indiana — a coal-fired facility that has operated for more than 50 years and stands among the state’s major electricity generation installations. The facility:

  • Began operations in the 1960s, with subsequent unit additions expanding generating capacity
  • Operated multiple large coal-fired generating units capable of producing over 1,000 megawatts of electricity
  • Reportedly contained asbestos-containing materials (ACMs) throughout — in insulation, fireproofing, gaskets, and other applications — consistent with standard industrial construction practice for that era
  • Has undergone decommissioning and renovation activities that may have disturbed legacy asbestos materials

AES Indiana (formerly Indianapolis Power & Light Company) operated the facility. Petersburg sits within the broader Mississippi River industrial corridor — the stretch of heavy industry running along the Missouri and Illinois banks that includes major coal-fired generating stations such as:

  • Ameren’s Labadie Energy Center (Franklin County, MO)
  • Ameren’s Portage des Sioux Generating Station (St. Charles County, MO)
  • Granite City Steel and associated industrial complexes (Granite City, Illinois)

Workers, union dispatches, and contractors regularly crossed state lines throughout this corridor. Missouri- and Illinois-based tradesmen were regularly dispatched to Indiana facilities like Petersburg — and vice versa. That interstate work pattern matters: workers may have encountered identical asbestos-containing products from the same manufacturers across multiple states, potentially increasing cumulative exposure risk over an entire career.

Why Asbestos Was Used at Coal-Fired Power Plants

Extreme Operating Conditions Drove Asbestos Use

Coal-fired power plants operate under conditions that destroy most materials:

  • Steam temperatures exceeding 1,000°F at pressures reaching hundreds of PSI
  • Constant thermal and mechanical stress on boilers, turbines, condensers, pipes, and valves
  • Continuous maintenance cycles requiring repeated overhaul and repair of interconnected systems

Asbestos-Containing Materials: The Industry Standard for Decades

From the 1920s through the late 1970s, asbestos-containing materials matched power plant demands in ways no other affordable material could replicate:

  • Non-combustible at power plant operating temperatures
  • Dramatically reduced heat loss from pipes and equipment
  • Added structural integrity to gaskets, packing, and cement products
  • Resisted steam, acids, and corrosive agents
  • Insulated electrical applications
  • Fireproofed structural components

The same operating demands that drove asbestos-containing material use at Petersburg drove identical choices at Missouri facilities including Labadie Energy Center, Portage des Sioux Generating Station, and the Monsanto chemical complex in St. Louis County — facilities where workers represented by Missouri-based union locals were regularly dispatched throughout the same era.

Major Manufacturers Allegedly Supplied Petersburg and Missouri Facilities

Leading asbestos product manufacturers allegedly supplied facilities like Petersburg across the country, including:

  • Johns-Manville — thermal insulation, fireproofing products, and asbestos-cement materials
  • Owens-Illinois — asbestos-containing products and thermal insulation systems
  • Owens Corning — asbestos fiber glass composite insulation materials
  • Armstrong World Industries — floor tiles, ceiling tiles, and building system products containing asbestos
  • Combustion Engineering — boiler components and refractory materials
  • W.R. Grace — asbestos-containing sealants and specialty industrial products
  • Georgia-Pacific — asbestos-containing drywall and building materials
  • Crane Co. — valves and valve components with asbestos packing materials
  • Eagle-Picher — asbestos-containing gaskets and insulation products
  • Garlock Sealing Technologies — asbestos-containing gasket materials and sealing products

Internal corporate documents produced in litigation demonstrate that many of these manufacturers — including Johns-Manville, Owens-Illinois, and Armstrong World Industries — possessed research documenting asbestos health hazards decades before issuing any public warnings, yet continued marketing these products to the power generation industry. The same manufacturers allegedly supplied Indiana River and Mississippi River corridor facilities, meaning workers who moved between Indiana, Indiana, and Illinois job sites may have encountered identical products from the same suppliers throughout their careers.

Timeline: When Asbestos-Containing Materials Were Present

Construction Era (1960s–1970s)

Original construction and subsequent unit additions at Petersburg reportedly occurred during the peak years of asbestos use in American industrial construction. Workers involved in that construction — including those dispatched through Missouri-based union locals — may have been exposed to asbestos-containing materials from multiple manufacturers, including:

  • Insulators installing thermal insulation products such as Kaylo, Thermobestos, and other asbestos-containing block and pipe insulation
  • Pipefitters working on pipe systems subsequently insulated with asbestos-containing materials, per typical power plant construction sequencing
  • Boilermakers constructing boiler systems with asbestos linings and refractory materials
  • Ironworkers and electricians working with asbestos fire protection and electrical insulation products, including Monokote fireproofing

Union dispatch records and pension fund records may help document the presence of specific members at Petersburg during the construction era — evidence that can prove decisive in establishing exposure history for a mesothelioma claim.**

Operational Maintenance Era (1960s–1980s)

Ongoing maintenance operations represent arguably the period of greatest exposure risk for Petersburg workers. Coal-fired plants require constant upkeep:

  • Boilers periodically taken offline for inspection and overhaul
  • Steam lines repaired for leaks and failures, routinely involving asbestos-containing gaskets and valve packing from manufacturers such as Garlock Sealing Technologies and Crane Co.
  • Turbines undergoing regular overhauls where asbestos-containing insulation and gaskets were disturbed
  • Pumps, valves, and mechanical components repacked and replaced using asbestos-containing materials

Workers may have encountered asbestos-containing materials on a daily or near-daily basis during this period. Members of Missouri-based trades were regularly dispatched to Petersburg and comparable Midwest power plants for major maintenance shutdowns. OSHA issued its first asbestos standard in 1971, but practical implementation of protective measures in operating industrial facilities routinely lagged behind the written requirements.

Missouri-based tradesmen working at Petersburg during this era faced the same asbestos-containing product exposures as their counterparts at Labadie, Portage des Sioux, and Granite City Steel — because the products, manufacturers, and supply chains were largely identical across the Mississippi River industrial corridor.

Renovation and Decommissioning Era (1980s–Present)

Legacy asbestos materials remained embedded in the plant long after new installation ended. Workers may have encountered them through:

  • Renovation and repair work disturbing previously installed asbestos-containing materials from Johns-Manville, Owens-Illinois, and Armstrong World Industries
  • Demolition and decommissioning activities as the plant reduced operations, with workers potentially encountering asbestos-containing building materials such as Gold Bond drywall products and Transite panels
  • Activities subject to EPA NESHAP requirements (National Emission Standards for Hazardous Air Pollutants)

NESHAP regulations require facilities to survey for asbestos before demolition and to abate asbestos-containing materials beforehand. NESHAP notifications and abatement records filed with state and federal environmental agencies may document the types and quantities of asbestos-containing materials identified at the facility (per NESHAP abatement records). Indiana- and Illinois-based contractors performing abatement work at Petersburg during this era may have been exposed to materials that had sat undisturbed for decades — often the most dangerous condition for fiber release.Call an experienced asbestos attorney indiana today.**

Which Workers May Have Been Exposed

Asbestos exposure at Petersburg was not limited to workers who directly handled asbestos-containing materials. When ACMs are disturbed, fibers become airborne and remain suspended for hours. Workers performing unrelated tasks in the same area may have inhaled them without knowing it.

Insulators (Heat and Frost Insulators Local 1, St. Louis)

Insulators faced among the highest asbestos exposure risks of any trade:

  • Mixed asbestos-containing cements from powder form, including products from Johns-Manville and W.R. Grace
  • Sawed, cut, and shaped asbestos-containing block insulation such as Kaylo, Thermobestos, and Aircell
  • Applied asbestos-containing lagging to boiler surfaces
  • Removed old, degraded asbestos insulation during maintenance and overhaul

Every one of those tasks — mixing, cutting, sawing, and stripping — generates the respirable fiber clouds that cause mesothelioma. Insulators at Petersburg and at Missouri corridor facilities worked with identical products from the same manufacturers throughout their careers.
