If you or a loved one has been diagnosed with mesothelioma, asbestosis, or another asbestos-related disease potentially linked to work at this or any other facility, consult a qualified asbestos attorney immediately.

Urgent Filing Deadline Warning: Indiana asbestos Statute of Limitations

If you worked at Tanners Creek Generating Station and have since been diagnosed with mesothelioma, asbestosis, or another asbestos-related disease, the clock is already running. Indiana’s statute of limitations for asbestos disease claims is 2 years from the date of diagnosis** under Ind. Code § 34-20-3-1. Miss that deadline, and your right to compensation is gone — permanently.

If You Just Received a Diagnosis, Read This First

A mesothelioma diagnosis typically arrives 20 to 50 years after the exposure that caused it. The plant where you worked in 1972 is directly connected to the diagnosis you received last month. That connection is compensable — but only if you act before your legal deadline expires.

You may have rights to compensation through asbestos lawsuits, asbestos trust funds, or both. The companies that manufactured the asbestos-containing materials reportedly installed at Tanners Creek — Johns-Manville, Owens-Illinois, Garlock, W.R. Grace, and others — either established bankruptcy trusts or face ongoing civil liability. Billions of dollars remain available to qualifying claimants. This guide explains what may have happened at Tanners Creek, which trades faced the greatest exposure risk, and what you need to do now.

The Facility: Location, Ownership, and Construction History

The Tanners Creek Generating Station sits on the Ohio River in Lawrenceburg, Dearborn County, in southeastern Indiana. That riverfront location was not incidental — coal-fired steam generation consumes enormous quantities of water, and the Ohio River provided it.

Ownership and Corporate Structure:

Constructed and operated as an American Electric Power (AEP) facility
Managed through Indiana Michigan Power, the AEP subsidiary serving Indiana and Michigan
Liability for asbestos exposure may extend through multiple corporate successors, parent companies, and their insurers

Construction Timeline:

Unit 1: Reportedly came online in the early 1950s
Units 2 and 3: Added in subsequent years as postwar electricity demand grew
Unit 4: The largest unit, reportedly commissioned in the 1960s
The plant operated as an active coal-fired facility for many decades before decommissioning

Each construction phase brought waves of skilled tradespeople onto the site. Each phase reportedly involved installation of large quantities of asbestos-containing materials supplied by Johns-Manville, Owens-Illinois, and other major manufacturers. That layered construction history matters for litigation — exposure claims can attach to multiple phases, multiple contractors, and multiple product lines.

Why Asbestos-Containing Materials Were Used Throughout the Plant

Coal-fired power plants operate at conditions that would destroy ordinary materials within months. Steam at Tanners Creek reportedly passed through pipes, valves, turbines, and boilers at temperatures exceeding 1,000 degrees Fahrenheit and pressures of thousands of pounds per square inch. From the 1930s through the late 1970s — and in some cases into the 1980s — asbestos-containing materials were the engineering standard for those conditions. There was no widely available substitute, and the industry knew it.

Reported uses of asbestos-containing materials at Tanners Creek:

Pipe and boiler insulation: Products including Kaylo (Johns-Manville) and Thermobestos pipe covering on steam lines throughout the facility
Gaskets: High-pressure flange and valve sealing materials supplied by Garlock Sealing Technologies and others
Valve packing: Asbestos-containing braided packing in pumps, valves, and rotating equipment
Structural fireproofing: Sprayed-on and troweled-on products including Monokote (W.R. Grace)
Refractory materials: Boiler walls, furnace linings, and high-heat surfaces, including Cranite (Crane Co.)
Electrical insulation: Switchgear components and wiring insulation from Johns-Manville and Armstrong World Industries
Roofing and flooring: Products including Gold Bond and Sheetrock (Armstrong World Industries)
Turbine insulation and lagging: Products from Johns-Manville and Owens-Corning

Every major power producer in the United States reportedly used these same materials during this period. What distinguishes Tanners Creek for litigation purposes is the volume of asbestos-containing materials allegedly installed across multiple construction phases, the plant’s long operational life, and the nature of repetitive maintenance work that required workers to cut, remove, and disturb those materials year after year.

When Workers May Have Been Exposed to Asbestos-Containing Materials

Construction Era: 1950s Through 1960s

The period of greatest reported asbestos-containing material installation corresponds to the plant’s construction and expansion. Workers in the insulation, pipefitting, and general construction trades who performed work during this era may have been exposed to substantial concentrations of airborne asbestos fibers during installation of:

Pipe covering and block insulation, including Kaylo and Thermobestos, on steam lines
Boiler insulation and refractory materials, including Cranite (Crane Co.)
Turbine insulation and lagging from Johns-Manville and Owens-Corning
Electrical insulation from Armstrong World Industries and Johns-Manville
Fireproofing products including Monokote (W.R. Grace)
Roofing and flooring materials including Gold Bond and Sheetrock (Armstrong World Industries)

Maintenance and Operations Era: 1950s Through 1980s

Power plants require constant maintenance. Boilers must be inspected and repaired. Steam pipes develop leaks. Valves must be repacked. Turbines must be overhauled. Each maintenance cycle at Tanners Creek reportedly created new asbestos exposure opportunities:

Cutting into asbestos-containing pipe insulation — including Kaylo and Thermobestos — to access pipe for repair
Removing asbestos-containing gaskets supplied by Garlock Sealing Technologies from flanged connections
Repacking valves and pumps with asbestos-containing braided packing
Working near previously installed asbestos-containing materials that had degraded and become friable over time

Workers at Tanners Creek during the 1960s, 1970s, and 1980s may have been exposed to asbestos-containing materials installed years or decades before they arrived on site — materials they never touched but breathed.

Renovation, Abatement, and Decommissioning: 1980s Onward

As the asbestos hazard became publicly documented in the late 1970s and 1980s, utilities began programs to identify, encapsulate, and remove asbestos-containing materials. That abatement process itself generated significant fiber release when not conducted under proper containment. Workers involved in asbestos abatement at Tanners Creek, or those who worked in areas where asbestos-containing materials were disturbed during renovation or decommissioning activities, may also have been exposed during this later period.

Which Workers Face the Highest Exposure Risk

Any worker at Tanners Creek during its operational years may have been exposed to asbestos-containing materials. The following trades, however, consistently show the highest documented exposure levels in both occupational health research and decades of asbestos litigation across the power industry.

Insulators (Asbestos Workers)

Highest-risk occupation.

Insulators — historically called “asbestos workers” in the trades — are among the most heavily exposed occupational groups documented in asbestos litigation. Workers in this trade who performed work at Tanners Creek were allegedly:

Directly involved in installing, maintaining, and removing asbestos-containing pipe insulation products including Kaylo and Thermobestos, boiler insulation, and turbine lagging
Mixing asbestos-containing cements and mastics
Cutting asbestos-containing pipe covering to fit in the field
Working with loose asbestos-containing materials in confined spaces
Installing fireproofing products including Monokote (W.R. Grace)

These activities release fibers at high concentrations. Former members of Heat and Frost Insulators Local 1 (St. Louis) or Heat and Frost Insulators Local 27 (Kansas City) who performed work at Tanners Creek may hold the strongest direct exposure claims. An experienced mesothelioma lawyer indiana-based can evaluate your union membership and work history to identify every viable claim.

Pipefitters and Steamfitters

Pipefitters and steamfitters maintained and repaired the steam and water piping networks running throughout the plant. Their work allegedly involved:

Cutting and removing asbestos-containing pipe insulation including Kaylo and Thermobestos to access pipe for repair
Installing new pipe sections alongside existing asbestos-containing insulation
Working with asbestos-containing gaskets supplied by Garlock Sealing Technologies on flanged connections
Removing and replacing asbestos-containing valve packing
Working alongside insulators who were simultaneously cutting and applying asbestos-containing materials — the classic bystander exposure scenario

Pipefitters from UA Local 562 (St. Louis) and UA Local 268 (Kansas City) who worked at Tanners Creek may have been exposed both through direct product contact and through repeated bystander exposure to fiber releases by nearby trades.

Boilermakers

Boilermakers at Tanners Creek were responsible for installing, inspecting, maintaining, and repairing the plant’s boilers — the heart of every coal-fired generating station. Their work allegedly involved:

Handling asbestos-containing insulation products, refractory materials including Cranite (Crane Co.), and packing integral to boiler construction and maintenance
Confined-space work inside boilers where asbestos-containing materials may have been present on interior surfaces
Repeated exposure during maintenance outages when boilers were dismantled for inspection and repair

Boilermakers represent one of the most heavily exposed occupational groups in asbestos litigation across the power industry. If you worked as a boilermaker at Tanners Creek, an asbestos attorney indiana-based should evaluate your claim without delay.

Electricians

Electricians at Tanners Creek installed and maintained electrical systems, switchgear, and power distribution equipment throughout the facility. Their work allegedly involved:

Direct contact with asbestos-containing electrical insulation materials from Johns-Manville and Armstrong World Industries
Regular proximity to insulation and fireproofing work performed by other trades in shared work areas
Disturbing asbestos-containing materials when running conduit or pulling wire through areas where those materials had degraded

Electricians handled asbestos-containing materials less frequently than insulators or boilermakers, but they worked in the same confined spaces, often simultaneously. Bystander exposure in an enclosed boiler room is not meaningfully different from direct handling exposure.

Millwrights and Machinery Technicians

Millwrights who serviced turbines, generators, pumps, and rotating equipment at Tanners Creek may have been exposed through:

Installing and removing asbestos-containing packing in rotating equipment
Working in direct proximity to asbestos-containing pipe insulation on adjacent steam piping
Participation in major turbine overhauls where asbestos-containing materials were present throughout the work area

Laborers and General Workers

General laborers at Tanners Creek were not asbestos specialists, but may have been exposed through:

Proximity to construction, maintenance, and abatement activities involving asbestos-containing materials from Johns-Manville, Owens-Illinois, and other manufacturers
Handling or staging materials that reportedly contained asbestos
Cleanup activities after maintenance or construction work where disturbed asbestos-containing materials had settled on surfaces

Construction Workers and Contractors

Subcontractors and specialized tradespeople who worked on renovation, expansion, and decommissioning projects at Tanners Creek may have been exposed to asbestos-containing materials installed during earlier construction phases — materials they had no direct role in placing but distur
