Trimble County Station: Facility History and Asbestos Exposure Overview

Location and Operating History

The Trimble County Generating Station sits along the Ohio River in Bedford, Kentucky, approximately 35 miles northeast of Louisville. Louisville Gas and Electric Company operates the facility as a subsidiary of PPL Corporation and is one of Kentucky’s largest electric utilities — operating multiple generating stations across the Commonwealth, all of which share a common construction-era history involving asbestos-containing materials.

Construction and Operations Timeline:

Unit 1: Construction began in the late 1970s; commercial operation commenced in 1984 with a capacity of approximately 495 megawatts
Unit 2: Commercial operation began in 2011, adding additional generating capacity

The station operates as a conventional coal-fired steam electric generating unit: coal combustion generates heat, which converts water to high-pressure steam, which drives turbines connected to electrical generators. The facility reportedly supplied electricity to hundreds of thousands of Kentucky homes and businesses throughout the LG&E service territory.

Why Coal-Fired Power Plants Specified Asbestos-Containing Materials

Steam temperatures in boilers at the Trimble County facility reportedly exceeded 1,000 degrees Fahrenheit, and high-pressure steam piping ran throughout the plant at extreme temperatures and pressures. Managing heat transfer was both an engineering necessity and an economic decision.

Asbestos-containing materials were specified because they were lightweight, inexpensive, and durable under extreme heat — and because they were aggressively marketed as safe by major manufacturers including Johns-Manville Corporation, Owens-Illinois, Owens Corning, Armstrong World Industries, W.R. Grace, and Georgia-Pacific to power plant builders and utilities throughout Kentucky. That marketing was false. Asbestos causes mesothelioma, and the manufacturers knew it.

Unit 1 came online in 1984, when regulatory restrictions on asbestos were tightening, but construction stretched across several years during which asbestos-containing materials were reportedly still specified and installed. Pre-existing asbestos-containing materials in older equipment, residual stock insulation, and transition-era products may all have contributed to worker exposures during that period. This pattern closely parallels documented exposure history at other Kentucky LG&E facilities and comparable coal-fired generating stations that operated throughout the Commonwealth during the same era.

Asbestos-Containing Products Allegedly Present at Trimble County Station

Based on the documented history of comparable Kentucky power plants and coal-fired utilities from the same construction era — including other LG&E generating stations, Armco Steel’s Ashland, Kentucky facility, and General Electric’s Appliance Park in Louisville — the following types of asbestos-containing materials were allegedly used or may have been present at this facility.

Block Insulation

Large-format block insulation — typically calcium silicate or magnesia blocks reinforced with asbestos fibers — was reportedly used throughout the boiler house and turbine building to insulate large-diameter piping, valve bodies, turbine casings, and steam headers. Cutting, shaping, or breaking this insulation during installation or maintenance could release large quantities of respirable asbestos fibers directly into the breathing zone of nearby workers.

Kentucky insulators, pipefitters, and boilermakers who moved between multiple generating stations and industrial facilities across the Commonwealth may have encountered this same class of product repeatedly throughout their careers — accumulating exposures at each job site.

Manufacturers of asbestos-containing block insulation allegedly present at facilities of this type:

Johns-Manville Corporation — among the largest U.S. manufacturers of asbestos-containing block insulation; its products were widely specified at coal-fired power plants throughout Kentucky, including facilities comparable to Trimble County Station
Owens-Illinois and Owens Corning — manufactured and distributed insulation products containing asbestos or used in conjunction with asbestos-containing thermal systems
Armstrong World Industries — reportedly supplied asbestos-containing insulation products to power generation facilities of this type and era throughout the Commonwealth

Pipe Covering

Miles of steam piping connect the boiler, turbine, feed water heaters, condensers, and auxiliary systems throughout a coal-fired generating station. Asbestos-containing pipe covering — preformed half-round insulation sections — was standard throughout the power generation industry and was widely used at Kentucky utilities during the construction era relevant to Trimble County Station.

Asbestos content in pipe covering products could range from approximately 15 to 50 percent by weight. Cutting or trimming materials such as Kaylo and Thermobestos brand pipe coverings with saws or knives could reportedly generate visible clouds of dust containing asbestos fibers — exposing not only the worker doing the cutting but every tradesperson working in the same space.

Manufacturers of asbestos-containing pipe covering allegedly used at facilities of this type:

Johns-Manville Corporation — its pipe covering products were reportedly among the most widely distributed in the country and used at comparable Kentucky power plants
Owens-Illinois and Owens Corning — also supplied pipe covering products that may have been present at this facility
W.R. Grace — manufactured thermal insulation products containing asbestos for industrial applications, including Kentucky power generation facilities
Georgia-Pacific — reportedly supplied asbestos-containing building and thermal products to industrial facilities across Kentucky

Boiler Insulation and Refractory Materials

The steam boilers at Trimble County reportedly required extensive multi-layer insulation systems: refractory brick or castable refractory closest to the firebox, insulating block or blanket in the middle layer, and an outer finish coat. Asbestos-containing components in these systems reportedly included asbestos blanket insulation, asbestos-containing refractory cement, and asbestos rope packing.

Combustion Engineering, Inc. manufactured large utility steam boilers and reportedly supplied boiler systems and associated components to numerous American power plants, including facilities in Kentucky. Workers who may have performed maintenance, inspection, or repair work on Combustion Engineering boiler systems at Trimble County Station could have been exposed to asbestos-containing materials associated with those systems.

Members of Boilermakers Local 40 (Louisville), which represented boilermaker craftsmen throughout the Louisville metropolitan area and surrounding Kentucky counties, may have worked at LG&E generating facilities and encountered these materials during boiler construction, repair, and outage work.

Steam Turbine Insulation and Packing

Large steam turbines require insulation on their casings, steam chests, valves, and extraction points. Turbine insulation at facilities of this type typically incorporated asbestos-containing block insulation products, asbestos blanket insulation, and finishing cements containing asbestos fibers.

Asbestos-containing gasket materials and packing compounds were also reportedly used on turbine valve bodies, steam chest flanges, and extraction steam connections. Products manufactured by Garlock Sealing Technologies and Crane Co. — including asbestos-containing spiral-wound gaskets and valve stem packing — may have been present and required periodic replacement during maintenance outages. Workers removing or installing these materials may have been exposed to asbestos fibers in the process.

During maintenance outages, insulation workers, pipefitters, and other tradespeople removed existing insulation from turbine components — disturbing asbestos-containing materials and contaminating the air throughout the turbine building. Members of IBEW Local 369 (Louisville), which represented electrical workers at LG&E facilities, may also have been present in turbine building areas during those outages, potentially exposed to fibers disturbed by other trades working in the same space.

Feed Water Heater Insulation

Feed water heaters recover heat from extracted steam to preheat boiler feed water. These large cylindrical pressure vessels were typically insulated with asbestos-containing block insulation and asbestos-containing pipe covering. Boilermakers, pipefitters, and insulators performing maintenance on feed water heaters may have been exposed to asbestos-containing materials in the process.

Kentucky tradesmen who split their careers between Trimble County Station and other regional industrial facilities — including Armco Steel Ashland and the various LG&E power plants serving the Louisville metropolitan area — may have accumulated significant asbestos exposures across multiple job sites over the course of a working career.

Additional Asbestos-Containing Materials Throughout the Facility

Other asbestos-containing materials were reportedly present throughout the plant:

Asbestos gaskets and packing — products manufactured by Garlock Sealing Technologies and Crane Co. were reportedly used on virtually every flanged joint and valve stem in high-temperature service throughout the facility
Thermal spray insulation — asbestos-containing spray-applied fireproofing and thermal insulation applied to structural steel and other surfaces during construction
Floor tiles and adhesives — vinyl asbestos floor tiles and asbestos-containing mastics, potentially manufactured by Armstrong World Industries or Celotex, in plant buildings and administrative areas
Roofing materials — asbestos cement roofing products, potentially manufactured by Johns-Manville or Celotex
Electrical insulation — asbestos-backed electrical products and wiring insulation; members of IBEW Local 369 and other electrical trades who worked at this facility may have encountered these materials
Fireproofing materials — spray-applied asbestos-containing fireproofing, potentially including products such as Monokote or Aircell, applied to structural members in the boiler house and turbine building
Joint compound and drywall finishing materials — products such as Gold Bond and Sheetrock brand materials, some formulations of which allegedly contained asbestos, used during construction and renovation phases of the facility

Who Worked at Trimble County Station? High-Risk Trades and Occupations

Asbestos exposure at Trimble County was not limited to any single trade or craft. Multiple trades worked in close proximity throughout construction and maintenance operations. When one trade disturbed asbestos-containing materials, workers of every other trade in the same space breathed the same air — including those who never touched an asbestos-containing product directly. Bystander exposure is every bit as dangerous as direct-contact exposure, and the law treats it the same way.

High-risk occupations at this facility may have included:

Insulators — applied, removed, and replaced asbestos-containing pipe covering, block insulation, and boiler insulation throughout the facility
Boilermakers — worked directly on boiler systems, feed water heaters, and pressure vessels; may have disturbed asbestos-containing insulation and refractory materials during construction, repair, and outage work
Pipefitters and steamfitters — installed and maintained miles of steam and process piping throughout the plant; may have cut, trimmed, or disturbed asbestos-containing pipe covering and gasket materials
Electricians (IBEW Local 369) — worked throughout the turbine building, control rooms, and switchgear areas; may have been exposed as bystanders during insulation removal and installation by other trades
