About AEP Conesville Power Plant: Coshocton County Industrial History

Facility Location and Regional Workforce

The AEP Conesville Power Plant — formally known as the Conesville Coal Preparation and Power Generating Station — sits along the Muskingum River in Coshocton County, Ohio, approximately five miles east of the city of Coshocton. American Electric Power (AEP) owned and operated the facility through its subsidiary Ohio Power Company.

The Conesville facility drew its workforce from a broad regional area spanning Coshocton, Muskingum, Guernsey, Tuscarawas, and Holmes counties. Many workers employed at Conesville also worked at other major Ohio industrial facilities during their careers — including Cleveland-area steel mills, Akron rubber plants, and automotive assembly operations — creating compound exposure histories that experienced asbestos attorneys Ohio know how to document and prove in litigation.

If you worked at Conesville and have since been diagnosed with mesothelioma, asbestosis, or an asbestos-related lung cancer, Ohio’s two-year filing deadline is running right now. Speak with an experienced asbestos attorney Ohio immediately.

Decades of Operation and Workforce Scale

Conesville was among Ohio’s largest coal-fired electricity generating stations and served as the dominant industrial employer in the Coshocton region for more than fifty years:

Construction began: Late 1950s
First generating units operational: 1960
Major expansions: 1960s and 1970s
Peak employment: Hundreds of direct employees plus an extensive contractor and union trade workforce
Plant retirement and decommissioning: 2020

Generating Unit History and Capacity

The facility expanded progressively across four decades of operation (per EIA Form 860 plant data):

Units 1 and 2: Operational early 1960s
Unit 3: Operational mid-1960s
Unit 4: Operational 1973 (largest unit, approximately 810 megawatts)
Units 5 and 6: Expanded through the 1970s

Current Status: Decommissioning and Demolition

AEP retired Conesville in 2020 as part of its transition away from coal-fired generation. Demolition of a facility built largely in the 1960s raises documented concerns about asbestos-containing material abatement — disturbance of previously encapsulated asbestos-containing materials during demolition can release fibers, creating exposure risks for demolition workers, contractors, and nearby personnel.

The facility operates under an Ohio EPA Title V operating permit under the Clean Air Act. Ohio EPA Title V permit files and NESHAP asbestos abatement records for Conesville are available through public records requests and can serve as evidence in asbestos litigation.

If you worked in demolition, decommissioning, or abatement at Conesville and have since been diagnosed with mesothelioma or another asbestos-related disease, Ohio’s two-year statute of limitations runs from your diagnosis date — not your last day on the job. Call an asbestos attorney Ohio today.

Why Coal-Fired Power Plants Used Asbestos-Containing Materials

The Industrial Role of Asbestos in Electricity Generation

Coal-fired power plants are fundamentally heat-management systems. Superheated steam — often exceeding 1,000 degrees Fahrenheit — drives turbines to generate electricity. Mid-20th-century engineers specified asbestos-containing materials throughout these facilities because asbestos fiber resists extreme heat, does not burn, insulates effectively, and was cheap relative to available alternatives.

Ohio’s industrial economy — anchored by steel production in Cleveland and Youngstown, rubber manufacturing in Akron, and coal-fired power generation throughout eastern Ohio — made Ohio one of the largest consumers of asbestos-containing industrial products in the United States between the 1930s and 1970s. Workers who built and maintained Conesville were part of the same union trade workforce that constructed and maintained facilities including Cleveland-Cliffs Steel operations, Republic Steel in Youngstown, Goodyear manufacturing in Akron, B.F. Goodrich in Akron, and Ford’s Lorain Assembly Plant. These workers faced comparable, well-documented occupational asbestos exposure risks across multiple facility types throughout their careers.

Primary Asbestos-Containing Material Applications in Power Plants

Thermal Insulation Systems

Pipe insulation on superheated steam lines, hot water pipes, and condensate return lines — products such as Kaylo and Thermobestos asbestos-containing pipe covering were reportedly supplied by Johns-Manville and Owens-Illinois to industrial facilities of this type and era
Boiler block insulation and boiler casing insulation containing asbestos-containing materials
Turbine casing and rotor insulation, including Aircell and Monokote spray-applied asbestos-containing fireproofing systems
Equipment insulation allegedly containing chrysotile, amosite, and crocidolite asbestos fiber varieties throughout the facility
These product specifications were standard across the industry from the 1930s through the mid-1970s

Fire Resistance and Fireproofing Systems

Structural steel fireproofing and mechanical equipment fireproofing, potentially including spray-applied asbestos-containing products such as Monokote and Superex, historically supplied by W.R. Grace and Armstrong World Industries
Fire blankets and fire-resistant wrapping containing asbestos-containing materials
Rope gaskets and rope packing materials containing asbestos fiber in high-temperature service
Packing materials in high-heat equipment areas reportedly supplied by manufacturers including Garlock Sealing Technologies and Eagle-Picher
Arc chutes and electrical fire-suppression equipment components allegedly containing asbestos-containing materials

Gaskets, Seals, and Mechanical Packing

Compressed asbestos fiber (CAF) gasket sheet on thousands of flange connections throughout facilities of this type, reportedly supplied by Garlock Sealing Technologies, John Crane Inc., and comparable manufacturers
Braided asbestos fiber packing in valve stems, pump seals, and rotating mechanical equipment
Asbestos-containing products also reportedly supplied by Armstrong World Industries for mechanical packing and sealing applications in power generation equipment

Electrical Insulation Components

Asbestos-containing electrical insulation on cables and conductors allegedly supplied by manufacturers including Johns-Manville
Arc chutes and electrical arc-suppression materials containing asbestos fiber
Panel liners and panel insulation containing asbestos-containing materials
Wire insulation in high-temperature electrical applications

Asbestos-containing refractory cements and castable refractories reportedly supplied by manufacturers such as Combustion Engineering
Insulating refractory block containing asbestos-containing materials
Cranite and comparable asbestos-containing refractory products are alleged to have been standard specifications in facilities built and expanded during the 1950s through 1970s

Timeline of Alleged Asbestos-Containing Material Use at Conesville

Construction Phase: Late 1950s – 1973

During initial construction and phased expansion of Conesville’s generating units, asbestos-containing materials were at their peak industrial application. Workers who participated in construction of Units 1 through 4 may have encountered heavy concentrations of asbestos-containing materials allegedly supplied by Johns-Manville, Owens-Illinois, Owens Corning, W.R. Grace, Armstrong World Industries, and Garlock Sealing Technologies.

Many construction trades workers who built Conesville were members of Ohio union locals with extensive histories of industrial construction work across the state. Members of Asbestos Workers Local 3 (Cleveland), Boilermakers Local 900, Insulators and Allied Workers Local 54, and comparable union locals are among those who may have been dispatched to large Ohio power generation and industrial construction projects during this era — and who may have worked alongside tradespeople applying, cutting, or disturbing asbestos-containing materials on a daily basis.

The scientific and medical evidence that asbestos fiber causes mesothelioma, asbestosis, and lung cancer is unambiguous and was available to industry by the 1930s and 1940s — decades before Conesville was built. Asbestos product manufacturers, including Johns-Manville and Owens-Illinois, are alleged in court filings across multiple jurisdictions to have suppressed this evidence from workers and the public for decades.
