About Liberty Station Power Plant

For decades, power generation facilities across Kentucky and Illinois — including Ameren UE’s Labadie Energy Center in Franklin County, Portage des Sioux Power Plant in St. Charles County, Rush Island Energy Center in Jefferson County, and Sioux Energy Center in St. Charles County — were built and maintained using asbestos-containing materials.

The coal-fired and natural gas generating facilities operated by Ameren UE and other regional utilities powered residential, commercial, and industrial customers throughout the twentieth century. Labadie Energy Center (Franklin County), Portage des Sioux Power Plant (St. Charles County), Rush Island Energy Center (Jefferson County), and Sioux Energy Center (St. Charles County) are part of a broader Mississippi River industrial corridor that also includes facilities such as Monsanto chemical manufacturing complexes in Sauget and Queeny, Granite City Steel (now U.S. Steel Granite City Works) in Granite City, Illinois, and numerous other heavy industrial operations that drew on the same skilled labor pool throughout the region.

Power generation facilities built between the 1930s and 1970s rank among the most asbestos-intensive industrial environments ever constructed. Utility companies and their contractors specified asbestos-containing products because those products:

  • Withstood temperatures exceeding 1,000°F in boiler rooms, turbine halls, and steam distribution systems
  • Kept steam heat inside pipes and boilers, improving plant efficiency
  • Reduced fire risk in high-temperature environments common to coal-fired generation
  • Dampened noise from high-pressure steam and rotating machinery
  • Insulated wiring in heat-intensive areas throughout plant structures
  • Reinforced gaskets, rope packing, and cement products used in high-pressure connections
  • Cost less than available alternatives at the industrial scale required for large baseload generating stations

General Equipment at Liberty Station Power Plant

The equipment below represents the systems and infrastructure documented or typically present at this facility during the era when asbestos-containing materials were specified in industrial construction. This is general facility-equipment reference — not a legal attribution of any specific product, manufacturer, or exposure event to this facility. Material-category and manufacturer information is addressed in the AsbestosIndex Product Crosswalk linked under the records table below.

Documented Asbestos Evidence

The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Kentucky Department for Environmental Protection (Kentucky DEP) was notified under federal NESHAP rules, the work was logged, and the asbestos-containing material was confirmed and removed under regulated conditions. These are not allegations or estimates — they are paper records tying documented asbestos-containing material to this specific site.

No Kentucky DEP NESHAP abatement notifications have been identified for this facility in current public records. Per the framing above, absence of state-agency documentation should not be read as absence of asbestos — only as absence of a formal, regulated abatement event meeting reporting thresholds. Workers who recall encountering pipe insulation, block insulation, gaskets, or other asbestos-era construction materials at this facility may still have viable claims regardless of whether a state record exists.

Who May Have Been Exposed at Liberty Station Power Plant

Workers who spent careers maintaining boilers, steam lines, valves, and turbine equipment at these facilities may have been exposed to asbestos fibers. Members of Heat and Frost Insulators Local 1 (St. Louis), Plumbers and Pipefitters UA Local 562 (St. Louis), Boilermakers Local 27 (St. Louis), and related union locals staffed these power plants across multiple generations — and many of the same tradespeople moved between power plants, steel mills, petrochemical facilities, and refineries along the river corridor during their careers.

During initial plant construction at Labadie Energy Center, Portage des Sioux Power Plant, Rush Island Energy Center, and Sioux Energy Center, workers may have been exposed to asbestos-containing materials throughout virtually every phase of the work, including thermal insulation applied to boilers and steam drums, high-pressure steam distribution piping wrapped in insulation, turbine hall construction involving spray-applied fireproofing, and control rooms and electrical areas built using asbestos-containing ceiling tiles and panels. Members of Heat and Frost Insulators Local 1, UA Local 562, and Boilermakers Local 27 performed significant portions of the construction-phase insulation, pipefitting, and boiler installation work.

Daily maintenance work and scheduled outages may have generated repeated asbestos fiber release over the full productive lifetimes of workers, including boiler tube replacement and repair, valve and pump repacking using asbestos-containing rope packing and sheet packing, gasket removal and replacement on flanged high-temperature connections, turbine overhauls, pipe insulation repair, electrical maintenance, and boilermakers Local 27 members performing boiler repairs and refractory work.

Critical Filing Deadline & Next Steps

Kentucky law gives mesothelioma and asbestos-disease claimants 1 year from the date of medical diagnosis to file a personal-injury lawsuit (KRS § 413.140). For wrongful-death claims after an asbestos-related death, the filing window is 1 year from the date of death (KRS § 413.180). The two deadlines run on separate tracks — preserving one does not extend the other.

The personal-injury clock runs from diagnosis, not from exposure. Mesothelioma latency is typically 20 to 50 years, so workers exposed in the 1950s–1980s are being diagnosed today.

Practical first steps

  1. Document what you remember. Pay stubs, W-2s, union cards, photographs, coworker names, and dates of employment. The WorkChain widget on this page can save a copy you can email yourself.
  2. Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
  3. Identify household members. Spouses who laundered work clothing and children of plant workers are eligible for secondary-exposure claims when diagnosed with an asbestos-related disease.
  4. Speak with an asbestos attorney with Kentucky experience. The first conversation is free and confidential. Asbestos trust-fund claims and civil claims run on different tracks — both can be pursued in parallel.

Asbestos-Related Diseases

Asbestos fiber exposure can cause several specific diseases that typically appear decades after the original exposure. The latency period — the gap between exposure and diagnosis — usually runs 20 to 50 years. That's why workers exposed in the 1960s, 1970s, and 1980s are receiving diagnoses today.

Mesothelioma

A rare, aggressive cancer that affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal), or heart (pericardial). Mesothelioma is almost exclusively caused by asbestos exposure, which is why a mesothelioma diagnosis often points directly to historical workplace exposure. Average latency from first exposure to diagnosis is 30-50 years.

Asbestosis

A chronic, non-cancerous scarring of lung tissue caused by inhaled asbestos fibers. Asbestosis causes progressive shortness of breath, persistent cough, and reduced lung function. It does not improve with treatment, and it is a recognized basis for compensation under most trust schedules and civil claims.

Lung Cancer

Asbestos exposure significantly increases the risk of lung cancer, particularly when combined with a history of smoking. Asbestos-related lung cancer is compensable under the same trust schedules and civil claim avenues as mesothelioma.

Other Recognized Diseases

Pleural plaques, pleural thickening, laryngeal cancer, ovarian cancer, and certain gastrointestinal cancers are also recognized as asbestos-related under various trust schedules and case-law authorities, though eligibility and proof requirements vary by claim type.

If you have any of these diagnoses and you worked at this facility, lived with someone who did, or were exposed in any documented capacity, you may have a claim worth pursuing. Speak with an attorney before assuming you don't qualify.

Cross-State & Regional Corridor Workers

These Missouri and Illinois power plants sit within one of the most heavily industrialized corridors in North America — the Mississippi River industrial corridor stretching from Granite City and Alton, Illinois, through St. Louis and into St. Charles and Franklin Counties in Missouri. Workers from this region moved between power plants, steel mills, chemical plants, and refineries throughout their careers, and many were members of St. Louis-area union locals including Heat and Frost Insulators Local 1, UA Local 562, and Boilermakers Local 27.
