Your Rights After a Big Sandy Asbestos Diagnosis

For decades, the Big Sandy Power Plant in Louisa, Lawrence County, Kentucky — operated by Kentucky Power Company, an American Electric Power subsidiary — generated electricity across eastern Kentucky. The workers who built, maintained, and repaired that plant may have paid for it with their health.

Boilermakers, pipefitters, insulators, electricians, millwrights, and maintenance tradespeople who worked at Big Sandy may have been exposed to asbestos-containing materials throughout the plant’s operational life.

If you or a family member worked at Big Sandy and has been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease, you may have substantial legal rights — regardless of how many years have passed since the exposure. Former Big Sandy workers and their families have pursued legal claims and recovered Missouri mesothelioma settlements and verdicts. This article explains what reportedly occurred at Big Sandy, which workers faced the greatest risks, and how to protect your legal rights before Missouri’s five-year filing deadline expires.

Facility Overview and History

Location, Ownership, and Operating Units

The Big Sandy Power Plant sits in Louisa, Lawrence County, in the eastern Kentucky coalfields along the Big Sandy River. Kentucky Power Company, an American Electric Power (AEP) subsidiary, operated the facility.

The plant ran two coal-fired generating units:

Unit 1: Reportedly began commercial operation in 1963
Unit 2: Reportedly began commercial operation in 1969
Combined capacity: Approximately 1,100 megawatts at peak operation

Unit 1 was reportedly retired. Unit 2 was converted to natural gas as environmental and regulatory pressure mounted. Decommissioning and conversion work may have disturbed legacy asbestos-containing materials throughout the facility, potentially creating additional asbestos exposure events for workers on those projects.

Why Power Plants Were Built With Asbestos-Containing Materials

Coal-fired power plants operate under extreme heat, pressure, and chemical stress. Engineers in the 1950s and 1960s specified asbestos-containing materials because no adequate substitutes existed for many applications. Asbestos fibers remain stable above 1,000°F, resist flame, insulate against electrical current, and resist degradation from industrial acids and chemicals. They were also cheap.

When Big Sandy was designed and constructed, asbestos-containing materials were engineered into thermal, mechanical, and electrical systems throughout the plant.

What makes this legally actionable is what major asbestos manufacturers knew — and concealed. Manufacturers including Johns-Manville, Owens-Illinois, Owens Corning, Eagle-Picher, Garlock Sealing Technologies, W.R. Grace, and others held internal scientific evidence of asbestos’s health hazards decades before disclosing that information to workers. Internal corporate documents show certain manufacturers understood the connection between asbestos exposure and lung disease as early as the 1930s and 1940s and continued selling their products without adequate warnings.

Workers at Big Sandy were not told of these risks. They worked without proper respiratory protection because they were told — or led to believe — they were handling standard industrial materials.

Timeline of Alleged Asbestos Use at Big Sandy

Original Construction Era (Late 1950s–1969)

Insulators, pipefitters, boilermakers, and ironworkers involved in original construction and the Unit 2 addition may have been exposed to asbestos-containing materials during installation, allegedly including:

Pipe insulation on high-temperature steam lines, allegedly manufactured by Johns-Manville and Owens-Illinois
Boiler insulation and refractory block reportedly containing asbestos
Asbestos-containing gaskets and packing from Garlock Sealing Technologies
Turbine insulation and lagging materials
Asbestos-containing floor tiles and ceiling materials, reportedly including Gold Bond products
Electrical insulation and conduit materials reportedly containing asbestos

Construction-era exposure tends to be the most intense. Workers cut, shaped, and installed asbestos-containing products in enclosed spaces with no containment procedures and no respiratory protection.

Operational and Maintenance Era (1963–Retirement/Conversion)

Big Sandy required continuous maintenance, scheduled outages, and periodic capital improvements that generated decades of ongoing potential exposure:

Scheduled outages brought large numbers of contract tradespeople into the plant, including members of Heat and Frost Insulators Local 1 (St. Louis, MO), Plumbers and Pipefitters UA Local 562 (St. Louis, MO), and other craft unions
Insulation work continued throughout the operational period as steam line insulation — allegedly including products branded Kaylo, Thermobestos, and Aircell — degraded, was damaged, or was replaced
Boiler work repeatedly disturbed high-temperature insulation and refractory materials
Gasket and packing replacement was routine at valves, flanges, and pumps, reportedly using asbestos-containing products from Garlock Sealing Technologies and Armstrong World Industries
Turbine maintenance required sustained proximity to heavily insulated components

Workers faced both direct exposure from handling asbestos-containing materials and bystander exposure from dust generated by other trades working in the same confined areas.

Transition and Remediation Era (1980s–Present)

As the Clean Air Act and EPA NESHAP regulations took effect, Big Sandy reportedly undertook asbestos abatement, encapsulation, and removal activities. Workers involved in that work — abatement contractors, maintenance personnel, and oversight staff — may have been exposed to asbestos-containing materials if proper containment and respiratory protection procedures were not followed.

The decommissioning of Unit 1 and conversion of Unit 2 to natural gas may have disturbed legacy asbestos-containing materials throughout the facility, creating renewed exposure risk for workers on those projects.

Which Trades Faced the Greatest Asbestos Exposure at Big Sandy

Asbestos-related disease does not track job titles — it tracks dust. But certain trades faced heavier potential exposure based on what they handled and where they worked.

Insulators (Heat and Frost Insulators)

Insulators from Heat and Frost Insulators Local 1 (St. Louis, MO) and other locals installed, maintained, and removed the thermal insulation covering steam pipes, boilers, turbines, and high-temperature equipment throughout the plant. Before the mid-1970s, asbestos-containing materials were the standard material for those applications. For insulators working in that era, asbestos-containing products were not incidental — they were the primary working material.

Insulators at Big Sandy may have:

Cut asbestos-containing pipe insulation products — including Kaylo, Thermobestos, and Aircell, sometimes called “mag pipe” or magnesia pipe insulation — with saws, knives, and hand tools, generating substantial airborne dust
Applied asbestos-containing cement and finishing compounds allegedly manufactured by Johns-Manville
Removed deteriorated asbestos-containing insulation during repair and replacement work
Fabricated custom insulation fittings from asbestos-containing blanket materials reportedly manufactured by Owens Corning and W.R. Grace

Pipefitters and Steamfitters

Pipefitters from Plumbers and Pipefitters UA Local 562 (St. Louis, MO) and other locals worked on the high-temperature, high-pressure steam systems that drove power generation. That work placed them in constant proximity to asbestos-containing pipe insulation and required routine use of asbestos-containing gaskets and packing.

Pipefitters at Big Sandy may have been exposed through:

Cutting through asbestos-containing pipe insulation to reach pipe sections during repair
Removing and replacing asbestos-containing gaskets from Garlock Sealing Technologies and Armstrong World Industries at pipe flanges throughout the plant
Using asbestos-containing rope packing from Garlock in valve stems and pump seals
Working alongside insulation and boiler work performed by other trades in shared, enclosed areas

Gasket and packing work carried concentrated exposure risk. Pipefitters routinely removed old gaskets by scraping, grinding, or wire-brushing corroded flange faces — tasks that released asbestos fibers at close range, with no engineering controls and no respiratory protection.

Boilermakers

Boilermakers worked inside and around the boilers — the largest, hottest, and most heavily insulated components in the plant. That work placed them in direct contact with some of the most concentrated asbestos-containing materials on site.

Boilermakers at Big Sandy may have been exposed to:

High-temperature refractory brick and cement reportedly containing asbestos, allegedly supplied by Crane Co. and Combustion Engineering
Boiler insulation and blanket materials from Johns-Manville, Owens-Illinois, and Owens Corning
Asbestos-containing gasket and packing materials from Garlock Sealing Technologies
Asbestos dust generated during boiler cleaning, scaling, and repair operations
Asbestos-containing insulation disturbed during welding and torch-cutting

Boiler work is inherently dusty and difficult to isolate. Every worker in an adjacent area became a potential bystander exposure victim.

Electricians and Electrical Workers

Electricians worked with systems that reportedly relied on asbestos-containing materials for insulation and fire protection throughout the plant:

Electrical conduit wrapping and insulation reportedly containing asbestos
Pre-1980s cable insulation that may have incorporated asbestos-containing materials from manufacturers including Johns-Manville and Owens-Illinois
Asbestos-containing panel boards, switchgear, and distribution equipment
Asbestos-containing tape and wrapping materials

Many electrical workers did not recognize asbestos-containing materials as a hazard because those materials were not the focus of their daily tasks. Asbestos exposure does not require awareness — it requires only proximity.

Millwrights and Equipment Mechanics

Millwrights and equipment mechanics worked on turbines, pumps, motors, and rotating equipment throughout the plant. That work required disassembly, repair, and reassembly of equipment that allegedly incorporated asbestos-containing insulation, gaskets, and packing.

Millwrights at Big Sandy may have been exposed to:

Turbine insulation and lagging materials from Johns-Manville and Armstrong World Industries
Pump and motor insulation reportedly containing asbestos
Bearing packing materials from Garlock Sealing Technologies
Asbestos-containing vibration damping materials
Gaskets and seals in mechanical connections throughout the facility

Maintenance Workers and Plant Laborers

General maintenance workers and plant laborers may have been exposed through:

Handling and moving insulated pipe sections and equipment
Sweeping and cleaning areas where asbestos-containing insulation had been disturbed — an activity that resuspends settled asbestos fibers
General plant maintenance in areas reportedly containing asbestos-containing materials
Assisting specialized trades without full knowledge of the materials involved

Bystander exposure is an established legal and medical theory with decades of supporting science behind it. A worker who never personally handled asbestos-containing materials may still develop mesothelioma after years of working in areas where other trades generated asbestos dust.

Contract Workers and Outage Crews

Contract workers brought in for scheduled and emergency maintenance outages faced particular risks. These workers often had no ongoing employment relationship with the plant and may not have received regular safety briefings or been issued adequate respiratory protection. Outage schedules are compressed, and multiple trades work in the same areas simultaneously — conditions that concentrate airborne dust from asbestos-containing materials and increase exposure risk for every worker on site.

If you worked Big Sandy as a contractor during any outage period, your exposure history is legally significant even if you were only on site for days or weeks.
