About Prairie State Energy Campus Marissa Illinois
Prairie State Energy Campus is a coal-fired steam generating station near Marissa, in Washington County, Illinois, approximately 40 miles east of St. Louis. The facility generates approximately 883 megawatts (MW) of electrical power serving residential and commercial customers across multiple states, including Missouri.
Prairie State’s geographic position places it within the broader Mississippi River industrial corridor — a dense band of power generation, chemical manufacturing, steel production, and refinery operations stretching from Alton, Illinois south through Granite City, East St. Louis, and Marissa, while mirroring a similar concentration of industrial facilities on the Missouri side, including Labadie, Portage des Sioux, and the St. Louis metropolitan industrial complex. Workers across this corridor frequently moved between facilities, and union trades members — including members of Heat and Frost Insulators Local 1, UA Local 562 (Plumbers and Pipefitters), and Boilermakers Local 27 — routinely worked at multiple plants throughout their careers, potentially accumulating asbestos-containing material exposures across several sites and both states.
Prairie State was commissioned in 2012, but construction spanned several years before that date — a period when asbestos-containing materials remained present in specialized industrial applications and when previously manufactured ACMs were still being installed from existing inventory. The facility sits atop the Lively Grove Mine, an active underground coal mining operation that supplies fuel via conveyor directly to the plant.
The facility’s systems include: Large-scale boiler systems; High-pressure, high-temperature turbines; Miles of steam distribution piping; Pump, valve, and mechanical equipment systems; Electrical systems; and Building infrastructure. Each of these systems historically relied on asbestos-containing materials for insulation, gaskets, packing, and fireproofing.
Workers in the construction phase and those performing operations, maintenance, and outage work since 2012 may have been exposed to asbestos-containing materials during: Original equipment installation; Routine maintenance and repairs; Equipment replacement and upgrades; Major facility outages; and Renovation and modernization work.
General Equipment at Prairie State Energy Campus Marissa Illinois
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 Illinois Environmental Protection Agency (Illinois EPA) 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.

Who May Have Been Exposed at Prairie State Energy Campus Marissa Illinois
Many of the skilled trades workers who performed work at Prairie State were members of Missouri- and Illinois-based union locals who traveled to Prairie State from the Missouri side of the Mississippi. Union trades members — including members of Heat and Frost Insulators Local 1, UA Local 562 (Plumbers and Pipefitters), and Boilermakers Local 27 — routinely worked at multiple plants throughout their careers, potentially accumulating asbestos-containing material exposures across several sites and both states. Workers in the construction phase and those performing operations, maintenance, and outage work since 2012 may have been exposed to asbestos-containing materials during original equipment installation, routine maintenance and repairs, equipment replacement and upgrades, major facility outages, and renovation and modernization work.Critical Filing Deadline & Next Steps
Illinois law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (735 ILCS 5/13-202). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (740 ILCS 180/2). 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
- 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.
- Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
- 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.
- Speak with an asbestos attorney with Illinois 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
Prairie State Energy Campus sits approximately 40 miles east of St. Louis, placing it squarely within the dense Missouri-Illinois industrial corridor lining both banks of the Mississippi River. Workers from both sides of the river — including those who also labored at Missouri facilities such as Labadie Energy Center, Portage des Sioux Power Plant, Granite City Steel, and Monsanto chemical operations — may have faced comparable asbestos-containing material exposures and may have legal rights in both Missouri and Illinois courts. The same manufacturers who allegedly supplied asbestos-containing materials to Prairie State’s construction and operations are also alleged to have supplied comparable materials to Missouri facilities including Labadie, Portage des Sioux, and industrial complexes operated by Monsanto and Granite City Steel. Workers who moved between these facilities, as members of Heat and Frost Insulators Local 1, UA Local 562, and Boilermakers Local 27 commonly did, may have accumulated exposures at multiple sites across both states.Data Sources
