About Moreau Power Station Moreau Missouri

Moreau Power Station is an oil and gas-fired electric generating facility located along the Missouri River in Cole County, near Jefferson City, Missouri. Operations began approximately 1978 with a generating capacity of approximately 60.8 megawatts (MW). The facility was originally owned and operated by Union Electric Co. and is now operated by Ameren Corporation, successor to Union Electric following the 1997 merger with CIPSCO Incorporated.

Union Electric operated multiple large generating stations across Missouri, including the Labadie Energy Center (Franklin County), Portage des Sioux Power Plant (St. Charles County), Sioux Energy Center (St. Charles County), and Rush Island Energy Center (Jefferson County), along with extensive transmission infrastructure throughout the Missouri River and Mississippi River corridors. Ameren Corporation is now one of the largest investor-owned utilities in the United States, serving Missouri and Illinois. Its service territory tracks closely with the Mississippi River industrial corridor, encompassing facilities on both sides of the river where asbestos-containing materials were reportedly used extensively.

Moreau Power Station was built when asbestos-containing materials remained the industry standard in industrial construction. Asbestos-containing materials became standard in power generation because asbestos tolerates temperatures exceeding 1,000°F without combusting, resists acids and industrial chemicals, insulates against electrical conductivity, and can be cut and shaped to fit any application. For a facility like Moreau — where boilers, steam lines, turbines, and heat exchangers operate continuously under extreme heat and pressure — asbestos-containing products were the default choice for virtually every insulation and sealing application.

Who May Have Been Exposed at Moreau Power Station Moreau Missouri

Workers who may have been exposed during the construction phase (late 1970s) include insulators affiliated with Heat and Frost Insulators Local 1 (St. Louis, MO), pipefitters from Plumbers and Pipefitters UA Local 562 (St. Louis, MO), boilermakers affiliated with Boilermakers Local 27 (St. Louis, MO), electricians, laborers, welders, carpenters, and construction supervisors. Many of these same tradespeople reportedly worked at Labadie Energy Center, Portage des Sioux Power Plant, and Monsanto facilities in the St. Louis region during the same period, potentially compounding their total exposure to asbestos-containing materials across multiple Missouri job sites.

During ongoing operations, maintenance activities that reportedly disturbed asbestos-containing materials included reinsulating steam lines with calcium silicate insulation and pipe covering products, repacking valve stems with asbestos-containing braided packing from gaskets and packing, replacing asbestos-containing gaskets at flanged joints, repairing boiler and turbine components surrounded by installed asbestos-containing insulation, and routine mechanical system inspections in areas where asbestos-containing materials remained in place. Workers from Heat and Frost Insulators Local 1, Plumbers and Pipefitters UA Local 562, and Boilermakers Local 27 performing these tasks may have been repeatedly exposed to asbestos-containing materials throughout their time at the facility.

Thermal insulators applied, maintained, and removed insulation on virtually every heated surface at the plant, handling asbestos-containing materials including calcium silicate insulation and pipe covering, pipe and block insulation and gasket material, asbestos-containing cement, pipe insulation and spray fireproofing, and asbestos cloth and blankets. Pipefitters and plumbers installed, maintained, repaired, and replaced piping systems carrying steam, condensate, water, and hydraulic fluid, encountering calcium silicate insulation and pipe covering insulation on steam and hot water lines, asbestos-containing gaskets at flanged pipe joints, asbestos-containing valve packing materials and braided packing string, and asbestos-containing putty.

Critical Filing Deadline & Next Steps

Missouri law gives mesothelioma and asbestos-disease claimants 5 years from the date of medical diagnosis to file a personal-injury lawsuit (Mo. Rev. Stat. § 516.120). For wrongful-death claims after an asbestos-related death, the filing window is 3 years from the date of death (Mo. Rev. Stat. § 537.100). 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 Missouri 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

Missouri sits at the center of one of the most heavily industrialized corridors in North America. The Mississippi River industrial corridor — running from St. Louis south through St. Clair County and Madison County, Illinois, and north along the Missouri River through Cole County and beyond — concentrated power generation, chemical manufacturing, steel production, and refining operations within a relatively compact geographic area. Workers from Missouri and Illinois routinely crossed state lines for union work, meaning exposure histories often span both states and create legal options in multiple jurisdictions. Members of Heat and Frost Insulators Local 1 also reportedly performed insulation work at Labadie Energy Center, Portage des Sioux Power Plant, and Monsanto chemical facilities in St. Louis County during the same era, and those same documents have been introduced in asbestos cases filed in St. Louis City Circuit Court and in Madison County Circuit Court in Illinois — courts where Missouri and Illinois workers have successfully pursued claims against manufacturers for decades.
