Asbestos Exposure at Petersburg Generating Station Petersburg — Indiana: Former Worker Claims

Hire an Asbestos Attorney Indiana — Petersburg Generating Station Exposures May Support Major Claims

If you worked at Indianapolis Power & Light’s Petersburg Generating Station and have been diagnosed with mesothelioma, asbestosis, or lung cancer, an experienced mesothelioma lawyer Indiana specializing in asbestos litigation may help you recover substantial compensation. Workers who built, operated, and maintained this coal-fired power plant for decades may have been exposed to asbestos-containing materials that manufacturers including Johns-Manville, Owens-Corning, Owens-Illinois, Armstrong World Industries, and W.R. Grace reportedly knew were dangerous — but allegedly concealed that information from workers and employers.

An asbestos attorney Indiana with deep experience in power plant litigation can evaluate your exposure history, determine whether you qualify for court claims and asbestos trust fund recovery, and guide you through Indiana’s strict filing deadlines. Petersburg Generating Station’s decades of operation created widespread occupational asbestos exposure potential — your case may have significant value.

⚠️ CRITICAL INDIANA FILING DEADLINE: Your Two-Year Window Is Non-Negotiable

Indiana law imposes an absolute two-year statute of limitations on asbestos-related personal injury claims under Ind. Code § 34-20-3-1. This deadline applies to mesothelioma lawsuits, asbestosis claims, and lung cancer claims. The two-year clock begins running from the date of your diagnosis — not from the date of your exposure. If you were recently diagnosed, your filing deadline may be much closer than you realize.

Once Indiana’s two-year statute of limitations expires, no court can restore your right to file — your claim is permanently barred. This is not a suggestion. This is an absolute legal requirement. Workers and families who miss this deadline lose all court-based recovery rights, period.

How the Clock Works

Diagnosis date = Day 1. Your mesothelioma, asbestosis, or lung cancer diagnosis starts the clock.
Two years from diagnosis = Final deadline. You must file before this date — not on it.
Missing the deadline = Permanent loss of claims. No exceptions, no extensions, no second chances.

Workers exposed 20, 30, or 40 years ago but diagnosed recently still have a two-year window — but they must act immediately. That window is already closing.

Asbestos Trust Fund Claims: Different Timeline, Same Urgency

Asbestos bankruptcy trust fund claims do not carry identical court-imposed filing deadlines, but trust fund assets are actively depleting as thousands of victims file claims every year. Delays can result in reduced compensation awards because trusts operate under proportional distribution protocols — later filers may recover cents on the dollar compared to what earlier claimants received.

Indiana law permits simultaneous pursuit of court-based lawsuits AND asbestos trust fund claims. Workers diagnosed with mesothelioma or asbestosis can:

File a lawsuit in Indiana court within the two-year window
File claims with multiple asbestos bankruptcy trusts established by liable manufacturers
Recover from both sources simultaneously

Most workers do not know dual-track recovery is available. An asbestos attorney Indiana familiar with trust fund procedures can coordinate these parallel claims to maximize your total compensation. Do not leave money on the table because you did not know it existed.

Petersburg Generating Station: Location, Ownership, and Operational History

Petersburg Generating Station sits in Pike County, southwestern Indiana, approximately two miles outside the city of Petersburg along the White River. Indianapolis Power & Light Company (IPL) owns and operates the facility. IPL is a subsidiary of IPALCO Enterprises, Inc., itself owned by AES Corporation.

Construction Timeline: Four Units, Decades of Asbestos-Containing Materials

The facility was built in phases between the early 1960s and 1979:

Unit 1 — Construction began early 1960s; reportedly came online approximately 1967
Unit 2 — Reportedly came online approximately 1969
Unit 3 — Reportedly came online approximately 1972
Unit 4 — The largest unit; reportedly came online approximately 1979

By the time Unit 4 was completed, Petersburg Generating Station ranked among Indiana’s largest coal-fired plants. Each unit required hundreds of tradespeople and enormous quantities of asbestos-containing materials that were industry standard during this era.

The facility reportedly operated all four units for decades through the late 2000s and beyond. Petersburg Generating Station’s workforce spanned multiple generations of Indiana construction workers and plant employees affiliated with regional labor unions including Boilermakers Local 374, Asbestos Workers Local 18 (Indiana insulator union), and Indiana Pipe Trades affiliated locals, as well as other skilled trades organizations representing workers throughout southwestern Indiana and the broader Wabash Valley region.

Why Coal-Fired Power Plants Required Massive Quantities of Asbestos-Containing Materials

The Engineering Reality

Coal-fired steam generating stations burn coal to produce superheated steam that drives massive turbines connected to electrical generators. The engineering demands are extreme:

Boilers operate at temperatures exceeding 1,000°F
High-pressure steam lines carry steam at 800–1,000°F and pressures over 2,400 PSI
Turbines operate at similarly extreme temperatures
Feedwater heaters, condensers, heat exchangers, and miles of associated piping all generate intense, continuous heat

Thermal insulation was not optional — equipment fails without it, and heat loss renders the plant uneconomical. That engineering reality made asbestos-containing materials ubiquitous in every coal-fired plant built before the 1980s.

Asbestos as Industry-Standard Insulation

Throughout the 1940s–1970s — precisely when Petersburg was designed, constructed, and expanded — asbestos-containing materials dominated high-temperature insulation in industrial power generation. The industry standardized on asbestos because it is naturally fire-resistant and thermally non-conductive, it was inexpensive and abundantly available, and engineering standards endorsed it. Manufacturers including Johns-Manville, Owens-Corning, Owens-Illinois, Armstrong World Industries, and Combustion Engineering aggressively marketed these products while allegedly concealing known health hazards from purchasers and end users.

Internal company documents — discoverable in asbestos litigation — reveal that major manufacturers had scientific knowledge of asbestos dangers dating to the 1930s and 1940s, yet continued marketing and installing products in industrial facilities throughout the 1960s and 1970s without adequate warnings to workers.

Cumulative Exposure Across Indiana’s Industrial Landscape

The same product lines reportedly used at Petersburg were being installed simultaneously at:

U.S. Steel Gary Works in Lake County
Bethlehem Steel Burns Harbor in Porter County
Inland Steel East Chicago
Cummins Engine Columbus in Bartholomew County
Regional petroleum refineries, chemical plants, and manufacturing facilities across Indiana

Workers who built or maintained those facilities and later worked at Petersburg may have accumulated significant cumulative asbestos exposure across their careers. An asbestos attorney Indiana experienced in Lake County asbestos lawsuits and Gary Indiana asbestos litigation understands these multi-facility exposure histories and can build comprehensive claims reflecting total occupational burden — not just the years spent at one plant.

Asbestos-Containing Materials Reportedly Present at Petersburg Generating Station

Based on industry standards and documentation from comparable Indiana coal-fired power plants constructed during the same era, workers at Petersburg Generating Station may have been exposed to asbestos-containing materials including:

Pipe Insulation and Lagging

Hundreds of miles of steam, condensate, and feedwater piping would reportedly have been covered with asbestos-containing pipe covering — often pre-formed half-sections applied in multiple layers. Products may have included Kaylo, Thermobestos, and Superex. Manufacturers allegedly supplying these products included Johns-Manville, Owens-Corning, Owens-Illinois, Armstrong World Industries, and W.R. Grace.

Pipe insulation removal represents one of the most hazardous asbestos exposure scenarios. During maintenance “rip-out” — when old insulation is torn away to access underlying equipment — workers release massive concentrations of airborne fibers directly into their breathing zones. Indiana insulators affiliated with Asbestos Workers Local 18 who rotated among the state’s major industrial facilities — including Petersburg, U.S. Steel Gary Works, and Inland Steel East Chicago — may have encountered these same product lines repeatedly across their working careers, multiplying cumulative exposure with every job.

If you performed pipe insulation work at Petersburg and have received a mesothelioma diagnosis, contact an asbestos cancer lawyer immediately — your statute of limitations is running right now.

Boiler Insulation and Refractory Materials

The steam boilers at Petersburg were reportedly insulated with asbestos block insulation on exterior surfaces, asbestos cement mixed on-site for sealing and coating, asbestos-containing refractory cements and castables inside and around fireboxes and combustion chambers, and asbestos rope and wicking for sealing access doors and expansion joints. Products may have been marketed under trade names including Aircell and Superex. Major manufacturers of boiler-related asbestos-containing products during this construction era allegedly included Babcock & Wilcox, Combustion Engineering, Foster Wheeler, Eagle-Picher, and Carey-Canada.

Turbine and Generator Insulation

Steam turbines at Petersburg were reportedly extensively insulated with asbestos-containing materials: turbine blankets and packing containing woven or compressed asbestos, asbestos-containing gaskets at every flanged connection along steam pathways, and valve packing made from asbestos rope or braided asbestos fiber — including products potentially marketed under the names Unibestos and Cranite. Turbine manufacturers including General Electric and Westinghouse supplied equipment to Indiana and Midwestern plants with insulation specifications that routinely called for asbestos-containing materials during the relevant construction period.

Gaskets, Packing, and Sealing Materials

Every flanged pipe joint, valve bonnet, pump seal, and expansion joint in a steam plant requires gasket and packing materials rated for extreme temperatures and pressures. During Petersburg’s construction and operation, virtually all such materials may have contained asbestos. Common products came from manufacturers including Garlock Sealing Technologies, Crane Co., Johns-Manville, and A.W. Chesterton.

Gasket replacement is particularly hazardous: scraping away old material generates highly concentrated asbestos fiber release directly at the worker’s face and hands. Indiana pipefitters and boilermakers who performed gasket and packing work at Petersburg during scheduled maintenance outages may have been exposed to these materials repeatedly across decades-long careers.

Floor Tiles, Ceiling Tiles, and Fireproofing

Administrative buildings, control rooms, and ancillary structures at the facility reportedly contained:

Asbestos-containing floor tiles and floor tile mastic
Asbestos-containing ceiling tiles
Sprayed-on asbestos fireproofing applied to structural steel members

These materials were routinely supplied by manufacturers including Armstrong World Industries, Johns-Manville, and W.R. Grace (marketed under the Monokote trade name). Renovation, repair, and demolition work in areas with these materials may have exposed workers — including electricians, carpenters, and general maintenance employees — who had no reason to believe ceiling tiles or floor adhesives posed a health threat.

Electrical Equipment and Switchgear

Electrical components at Petersburg may have incorporated asbestos-containing materials in arc barriers, wire insulation, and panel components. Manufacturers of electrical equipment incorporating asbestos-containing materials during this era reportedly included General Electric, Westinghouse, and Square D. Electricians performing routine maintenance on switchgear and panel equipment may have disturbed these materials without any warning of the associated hazard.

Who May Have Been Exposed at Petersburg Generating Station

Asbestos-related disease does not discriminate by job title. Workers across every trade and classification who may have been present at Petersburg Generating Station during construction and operation potentially face asbestos disease risk:

Construction Trades During Plant Build-Out (1960s–1979)

Pipefitters and steamfitters — installed and maintained all high-pressure steam and condensate lines
Boilermakers — constructed, tested, and maintained the
