Former Cayuga Workers May Have Been Exposed to Asbestos-Containing Materials

You just got a diagnosis. Or someone in your family did. And you’re trying to figure out whether what happened at that Indiana power plant decades ago has anything to do with the disease you’re fighting right now.

The answer — for a significant number of former Cayuga Generating Station workers — is yes.

Former workers at Cayuga and their families face serious health risks from decades of asbestos-containing material use at this Duke Energy coal-fired power plant. Workers in construction, maintenance, and skilled trades may have been exposed to asbestos-containing materials throughout the facility’s construction and operation — conditions that cause mesothelioma, lung cancer, and asbestosis. This guide identifies what asbestos-containing materials you may have encountered, what diseases they cause, and what legal options exist — including options specifically available to Missouri and Illinois residents who worked at Cayuga or at comparable facilities throughout the Mississippi River industrial corridor.

Indiana’s 2-year statute of limitations under Ind. Code § 34-20-3-1 runs from the date of your diagnosis — not the date of your exposure.** With

Cayuga Generating Station: Facility Background

Industrial Coal-Fired Power Plant with Documented Asbestos-Containing Material History

The Cayuga Generating Station sits along the Wabash River near Cayuga in Vermillion County, Indiana. Duke Energy Indiana LLC, a subsidiary of Duke Energy Corporation, operates the facility.

Key facts:

Unit 1 came online in 1969; Unit 2 in 1970, with combined peak capacity of approximately 1,005 megawatts
Construction began in the late 1950s, when asbestos-containing materials were standard throughout industrial power generation
Employed hundreds of workers over decades — permanent plant staff, maintenance crews, and contract tradespeople
Previously operated as PSI Energy and Public Service Indiana before Duke Energy acquired ownership

Coal-fired power plants built during this era reportedly used asbestos-containing materials throughout their infrastructure. Workers employed during construction, initial commissioning, and subsequent maintenance operations may have been exposed to airborne asbestos fibers.

Many workers at Cayuga were not Indiana residents. Throughout the plant’s operational history, skilled tradespeople from Missouri and Illinois — traveling members of Heat and Frost Insulators Local 1, UA Local 562, and Boilermakers Local 27, among others — were dispatched to Indiana facilities for construction and maintenance outages. Former Cayuga workers who lived and worked in the Mississippi River industrial corridor — including the St. Louis metro area, southern Illinois, and communities along the Missouri and Illinois banks — retain legal rights in their home states regardless of where the exposure allegedly occurred.

Indiana residents: Your home-state legal rights travel with you. A Indiana diagnosis triggers Indiana’s statute of limitations and Indiana’s legal protections — even if your alleged asbestos exposure occurred across the state line in Indiana. Do not assume that because you worked at an Indiana facility, Indiana law doesn’t apply to you. Contact a Indiana asbestos attorney today.

Why Coal-Fired Power Plants Used Asbestos-Containing Materials

Asbestos-containing products became industry standard in coal-fired power generation because of specific industrial properties:

Heat resistance — withstands temperatures exceeding 2,000°F
Tensile strength — can be woven into textiles and formed into gaskets and seals
Thermal and electrical insulation — prevents heat transfer and allows safe electrical distribution
Chemical resistance — largely inert when exposed to industrial chemicals
Low cost — mined domestically and imported affordably

The U.S. power generation industry ranked among the most intensive users of asbestos-containing materials during the mid-twentieth century. Manufacturers including Johns-Manville, Owens-Illinois, Owens-Corning, Combustion Engineering, W.R. Grace, Armstrong World Industries, A.W. Chesterton, Crane Co., and Garlock Sealing Technologies reportedly supplied asbestos-containing products that may have been installed at Cayuga and similar facilities throughout Indiana, Missouri, and Illinois.

The same manufacturers who may have supplied asbestos-containing materials to Cayuga also reportedly supplied comparable facilities across the Mississippi River corridor — including Labadie Energy Center and Portage des Sioux Energy Center in Missouri, Granite City Steel in Granite City, Illinois, and industrial operations at Monsanto facilities in the St. Louis area. Workers whose careers took them across multiple facilities in this corridor may have accumulated significant cumulative asbestos-containing material exposure over time — and that cross-facility history is directly relevant to the strength of your legal claim.

What litigation has established: Asbestos manufacturers allegedly knew about lethal hazards long before workers received any warning. Internal documents recovered in litigation show that manufacturers including Johns-Manville and Owens-Corning concealed evidence of asbestos’s carcinogenic properties from workers for decades.

Where Asbestos-Containing Materials May Have Been Present at Cayuga

Asbestos-Containing Products and Locations Reportedly Present Throughout the Facility

Former workers at Cayuga may have been exposed to asbestos-containing materials in the following locations and applications:

High-temperature pipe insulation — products reportedly including Kaylo, Thermobestos, and Unibestos pipe coverings throughout steam generation and distribution systems
Boiler insulation and refractory materials — asbestos cement products surrounding furnace walls
Turbine insulation — on steam turbines and turbine casings, potentially including Monokote spray-applied fireproofing
Generator insulation — within electrical equipment potentially manufactured by Combustion Engineering
Fireproofing materials — Monokote, Aircell, and similar spray-applied products on structural steel throughout the plant
Floor tiles, ceiling tiles, and wall panels — products reportedly including Gold Bond, Sheetrock, and Pabco in buildings constructed during the asbestos era
Gaskets, packing, and sealing materials — products from Garlock Sealing Technologies, Crane Co., and A.W. Chesterton throughout pipe flanges and valve assemblies
Rope gaskets and furnace door seals — in boiler systems reportedly supplied by Johns-Manville and others
Calcium silicate block insulation — Cranite and similar high-temperature block products in elevated-temperature applications

Workers in multiple trades — not just insulators, but pipefitters, electricians, boilermakers, and general maintenance staff — may have encountered asbestos fibers during routine work, not only during dedicated insulation tasks.

The same product lines — Kaylo, Thermobestos, Unibestos, Garlock gaskets, Cranite block — were reportedly used at comparable Missouri and Illinois facilities throughout the same construction and operating era. Workers who may have handled these products at Cayuga may have handled identical materials at Labadie, Portage des Sioux, or facilities in the Granite City industrial corridor. That cross-facility exposure history matters enormously to the value of your legal claim — and it needs to be documented before memories fade and witnesses become unavailable.

When Were Workers Most Likely Exposed?

Construction Era (Late 1950s–1970): The Highest-Concentration Exposure Period

Workers who built Cayuga may have faced the highest asbestos fiber concentrations of any operational phase. This period included:

Ironworkers, pipefitters, insulators, boilermakers, and laborers — including traveling members dispatched from Heat and Frost Insulators Local 1 (St. Louis, MO) and Boilermakers Local 27 (St. Louis, MO) — installing original insulation systems with products reportedly including Kaylo and Thermobestos, along with boiler construction and turbine installation
Direct application of asbestos-containing pipe covering and block insulation using products that released substantial quantities of airborne fibers during handling, cutting, and installation
Limited respiratory protection in widespread use during this period
On-site fabrication of custom insulation components requiring workers to cut and shape asbestos-containing products including Unibestos and Superex

Missouri and Illinois tradespeople who worked on Cayuga’s construction in the late 1950s and 1960s were part of the same regional labor pool that built contemporaneous facilities along the Mississippi River corridor, including Labadie Energy Center (commissioned 1970) and Portage des Sioux Energy Center (commissioned 1958–1967). Workers whose careers spanned multiple facilities may have faced repeated and compounding exposure across job sites.

If you worked construction at Cayuga during this era and have since been diagnosed with an asbestos-related disease, you may be running out of time. Indiana’s 2-year clock started on your diagnosis date — and the 2026 legislative threat means that your ability to file against multiple asbestos trust funds simultaneously may be curtailed even sooner.

Initial Operations and Early Maintenance (1969–1975)

As the plant entered service, maintenance activities may have caused significant asbestos fiber release:

Routine maintenance — including valve packing adjustment and gasket replacement using asbestos-containing materials reportedly from Garlock and Crane Co. — disturbing previously installed materials during normal operations
Turbine cleaning and early overhaul work in enclosed boiler and turbine rooms where fiber concentrations may have remained elevated
Contract tradespeople brought in for early overhauls, including members dispatched from UA Local 562 (St. Louis, MO), working in conditions where airborne fiber levels were not yet routinely monitored or controlled

Major Overhaul and Outage Period (1975–1990): Repeated High-Dose Exposure

Scheduled maintenance outages reportedly produced some of the most exposure-intensive conditions at power generating facilities:

Systematic removal of insulation — particularly products reportedly including Kaylo and calcium silicate block — to access underlying pipes, valves, and equipment
Installation of replacement insulation, some of which may still have contained asbestos-containing products during portions of this period
Extended work in confined spaces with multiple trades working simultaneously, potentially including dispatched members of Plumbers and Pipefitters UA Local 562 (St. Louis, MO) and Heat and Frost Insulators Local 1 (St. Louis, MO) — the same union locals that reportedly staffed outages at Labadie and Portage des Sioux during this same era
Variable regulatory enforcement and inconsistent abatement practices throughout this transitional period

Workers diagnosed today who performed outage work at Cayuga during this period face a 5-year Indiana filing window that closes on the anniversary of their diagnosis. Do not let procedural delay cost you the recovery you have earned.

Regulatory Response and Ongoing Conditions (1990–Present)

The EPA and OSHA substantially tightened asbestos regulations during the 1980s and 1990s. Duke Energy Indiana reportedly became subject to NESHAP asbestos notification requirements governing renovation and demolition activities at the facility. Even under tighter regulatory conditions, however, asbestos-containing materials installed during prior decades may remain in place throughout the plant infrastructure — and workers performing maintenance, repair, or renovation activities may have been exposed to previously installed asbestos-containing materials during disturbance activities, even where proper abatement protocols were nominally in place
