Contact an asbestos cancer lawyer at a St. Louis-based firm now — legislative threats are narrowing your filing window.
⚠️ URGENT FILING DEADLINE FOR Indiana residents
Indiana’s asbestos statute of limitations gives you 5 years from diagnosis to file a personal injury claim (Ind. Code § 34-20-3-1). But your window may be closing faster than you think.
Pending 2026 legislation poses a direct threat: would impose strict new trust fund disclosure requirements for asbestos lawsuits filed after August 28, 2026. If this bill becomes law, filing after that date could significantly complicate your ability to recover from the dozens of asbestos bankruptcy trust funds — potentially worth hundreds of thousands of dollars to your family.
Do not wait. The only way to protect your claim from this legislative threat is to file before August 28, 2026. If you or a family member received a mesothelioma, lung cancer, or asbestosis diagnosis, the clock is already running.

What Was Harding Street Station?
A Major Indianapolis Power Plant with Decades of Alleged Asbestos-Containing Materials Use
Harding Street Station — also known as the E.W. Stout Generating Station and operated by Indianapolis Power & Light Company (IPL) and later AES Indiana — was one of Indianapolis’s largest coal-fired electrical generating facilities. Located along the White River in southwest Indianapolis, it supplied power to central Indiana for decades.
Facility History and Timeline
- 1940s–1950s: Original construction and initial expansion phases
- 1960s–1970s: Major capital expansion with additional generating units installed
- 1970s–1980s: OSHA regulations implemented; ongoing maintenance of asbestos-containing systems continued
- 1980s–2000s: Renovation and abatement activities as asbestos hazards became widely recognized
- Operator history: Indianapolis Power & Light Company (IPL) → AES Indiana (AES Corporation subsidiary)
The Mississippi River Industrial Corridor Connection: Why This Matters for Indiana residents
Harding Street Station was not an isolated facility. Coal-fired power generation stretched across the Midwest, and workers frequently moved between plants along the Mississippi River industrial corridor — the dense concentration of power plants, refineries, steel mills, and chemical facilities running through Missouri and Illinois.
Workers who may have been exposed to asbestos-containing materials at Harding Street Station often had prior or subsequent employment at Missouri and Illinois facilities, including:
- AmerenUE Labadie Energy Center (Franklin County, Missouri) — one of the largest coal-fired power plants in the United States, with documented asbestos-containing materials use
- Portage des Sioux Generating Station (St. Charles County, Missouri) — a coal-fired plant along the Mississippi River where insulators, boilermakers, and pipefitters allegedly worked with asbestos-containing materials
- Granite City Steel (Granite City, Illinois) — a major steel facility where high-temperature industrial processes reportedly drove extensive asbestos-containing materials use
- Monsanto Chemical Facilities (St. Louis area, Missouri) — chemical manufacturing operations where workers from Heat and Frost Insulators Local 1 and UA Local 562 reportedly performed work involving asbestos-containing materials
Workers who accumulated asbestos exposure across these facilities in multiple states may have legal claims in Indiana and other jurisdictions. For Indiana residents, understanding your state’s asbestos lawsuit laws — and the August 28, 2026
Why Harding Street Station Was High-Risk for Asbestos Exposure
As a coal-fired steam generation facility, Harding Street Station operated systems that allegedly incorporated asbestos-containing materials throughout:
- Boilers heated to over 1,000°F requiring asbestos-containing insulation
- High-pressure steam systems using asbestos-containing gaskets, packing, and pipe covering
- Continuous 24/7 operation with ongoing maintenance and exposure to deteriorating asbestos-containing materials
- Hundreds to thousands of workers — including permanent employees, union workers, and contractors from Heat and Frost Insulators Local 1 (St. Louis) and UA Local 562 (St. Louis Plumbers and Pipefitters), many of whom worked across multiple Midwest power plants
Why Coal-Fired Power Plants Used Asbestos-Containing Materials
Steam Power Generation Required Heat-Resistant Materials
Coal-fired power plants burn coal to heat water into high-pressure steam, which drives turbines connected to electrical generators. This process imposed thermal and mechanical demands that manufacturers met — for decades — almost exclusively with asbestos-containing materials.
Temperature and Pressure Requirements:
- Boilers reportedly operated at temperatures exceeding 1,000°F
- Steam systems maintained high-pressure environments requiring tight, durable seals
- Plants ran continuously for months before scheduled maintenance shutdowns
Why Manufacturers Chose Asbestos-Containing Products:
- Superior heat resistance — chrysotile and amphibole asbestos fibers withstand temperatures far exceeding those of alternative materials available at the time
- Exceptional insulation properties — minimizes heat loss from pipes and protects workers from burn injuries
- High tensile strength — reinforces gaskets and sealing materials under extreme mechanical stress
- Chemical resistance — withstands acids, lubricants, and steam condensate common in power plant environments
- Low cost — heavily marketed and inexpensive throughout the twentieth century
Manufacturers Concealed Known Hazards
By the 1930s and 1940s, manufacturers including Johns-Manville, Owens-Illinois, and Armstrong World Industries had internal documentation showing asbestos fibers caused serious — often fatal — health conditions. They systematically concealed this information from workers and the public for decades.
Coal-fired power plants became some of the most dangerous asbestos exposure environments in American industry. Missouri and Illinois workers at facilities like Labadie, Portage des Sioux, and related plants were among those most heavily affected by this deliberate concealment.
That concealment has legal consequences. Manufacturers have been held accountable in courts across the country, and billions of dollars now sit in asbestos bankruptcy trust funds available to diagnosed workers and their families. Accessing those funds requires filing — and filing before
Timeline of Alleged Asbestos-Containing Materials Use (1940s–2000s)
1940s–1950s: Original Construction and Early Expansion
During initial construction and early expansion, asbestos-containing materials from manufacturers including Johns-Manville, Owens-Illinois, Garlock Sealing Technologies, and Crane Co. were allegedly incorporated into major building and mechanical systems. This era preceded any meaningful regulatory oversight of workplace asbestos exposure.
Asbestos-containing materials reportedly used during this period:
- Block and blanket insulation (Johns-Manville products)
- Pipe covering and thermal wrapping (Owens-Illinois, Johns-Manville)
- Boiler insulation and refractory materials from multiple manufacturers
- Fireproofing applications incorporating asbestos-containing board and spray materials
- Gaskets and valve packing (Garlock Sealing Technologies)
- Rope and cord packing (Crane Co.)
Workers who may have been exposed during this period include construction crews, boilermakers, insulators, and pipefitters — including members of Heat and Frost Insulators Local 1 (St. Louis) and UA Local 562.
1960s–1970s: Major Expansion and Peak Asbestos-Containing Materials Use
Harding Street Station reportedly underwent significant capital expansion during this period, including installation of additional generating units. The 1960s and 1970s represent peak asbestos-containing materials use across American industrial facilities — and the highest cumulative exposure period for many workers now receiving diagnoses.
Asbestos-containing products allegedly used:
- Kaylo and Thermobestos asbestos-containing block and pipe insulation (Johns-Manville)
- Monokote spray-applied asbestos-containing fireproofing (W.R. Grace)
- Aircell asbestos-containing insulation materials (Armstrong World Industries)
- Turbine insulation and blanket materials (Johns-Manville, Owens Corning)
- Gaskets and valve packing (Garlock Sealing Technologies, Crane Co.)
- Asbestos-containing refractory materials for boiler systems
- Thermal barrier and duct insulation materials
Workers who may have encountered high concentrations of airborne asbestos fibers include construction trades, electricians, pipefitters, and turbine installers — among them Heat and Frost Insulators Local 1 and UA Local 562 members. These same unions served workers across Indiana power plants, creating potential for multi-site asbestos exposure that strengthens the legal claims of Indiana residents.
1970s–1980s: OSHA Regulations and Ongoing Maintenance Exposure
The 1970s brought the first federal OSHA asbestos exposure standards (1972, 1975, 1986), yet asbestos-containing materials already installed throughout the facility remained in place. Ongoing maintenance and repair work exposed subsequent generations of workers to deteriorating asbestos-containing materials — often without adequate protection, warning, or disclosure.
Common maintenance tasks that may have created asbestos fiber release:
- Insulation repair and replacement on steam lines and piping
- Gasket and packing removal and installation
- Boiler maintenance and tube replacement
- Pipe fitting and valve work
- Mechanical seal replacement in pumps
- Fireproofing repair and reapplication
- Turbine overhaul and seal replacement
These tasks were performed by union tradespeople — members of Heat and Frost Insulators Local 1, UA Local 562, and Boilermakers Local 27 (St. Louis) — many of whom worked across
