About MEPI GT Facility Joppa Illinois
The MEPI GT Facility in Jopla, Illinois — Massac County, at the state’s southernmost tip — operated as a power generation and oil/gas processing installation for nearly five decades.
- Operational period: Approximately 1974–2022
- Generating capacity: Approximately 65 megawatts (MW)
- Primary function: Oil and gas processing and electricity generation
- Status: Closed in 2022
The facility was built around 1974 — a period when OSHA (established 1970) was still developing its asbestos exposure standards and EPA had not yet enacted NESHAP demolition and renovation requirements.
The nearly 50-year operational history means workers and contractors who may have been exposed to asbestos-containing materials at this facility can develop asbestos-related diseases decades after that exposure. Facilities like the MEPI GT Jopla plant carried exceptionally dense asbestos-containing material inventories because of steam generation systems requiring extensive pipe insulation, turbines and generators with high-temperature insulation on casings and connections, oil- or gas-fired boilers encased in asbestos-containing insulation blankets, heat exchangers and condensers with insulated pipe connections and flange gaskets, control rooms and switch houses insulated and fireproofed with asbestos-containing materials, expansion joints in high-temperature piping with asbestos-containing packing materials, and valve packing throughout oil and gas processing lines.
General Equipment at MEPI GT Facility Joppa 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.
No Illinois EPA 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 MEPI GT Facility Joppa Illinois
Workers on the original construction — insulators potentially from Heat and Frost Insulators Local 1 (St. Louis, MO) or Heat and Frost Insulators Local 27 (Kansas City, MO), pipefitters potentially from Plumbers and Pipefitters UA Local 562 (St. Louis, MO), boilermakers potentially from Boilermakers Local 27 (St. Louis, MO), electricians, and laborers — may have been exposed to airborne asbestos fibers during installation of pipe and equipment insulation, fireproofing application using spray-applied asbestos-containing products, installation of gaskets and electrical components, and general construction dust generated by cutting, fitting, and handling asbestos-containing materials.
Continuous operations required ongoing maintenance that may have disturbed asbestos-containing materials and allegedly generated elevated airborne fiber concentrations through pipe insulation removal and replacement, boiler tube replacement, gasket and flange work, valve repacking, turbine overhauls, electrical system maintenance, equipment modification and repairs, and conduit and wiring work. Many of these maintenance outages were staffed by union contractors based in St. Louis or the Metro East region of Illinois, drawing from the same Heat and Frost Insulators Local 1, UA Local 562, and Boilermakers Local 27 membership.
Insulators carry the highest documented asbestos exposure risk of any trade at facilities of this type.
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
The Jopla facility sits at the heart of the Mississippi River industrial corridor — a densely industrialized zone stretching from St. Louis northward through Missouri and southward into the extreme tip of Illinois, encompassing some of the most asbestos-intensive industrial infrastructure in the American Midwest. Facilities across this corridor — including AmerenUE’s Labadie Energy Center in Franklin County, Missouri, the Portage des Sioux Power Station in St. Charles County, Missouri, Monsanto Chemical operations in Sauget, Illinois and St. Louis, Missouri, and Granite City Steel in Madison County, Illinois — reportedly relied heavily on asbestos-containing materials throughout their operational histories.
Missouri workers frequently moved between facilities along this corridor, and union locals such as Heat and Frost Insulators Local 1 (St. Louis), UA Local 562 (St. Louis), and Boilermakers Local 27 (St. Louis) dispatched members to job sites on both sides of the Mississippi River. A worker whose primary employer was a Missouri facility may have accumulated significant asbestos exposure at Jopla as well. Heavy asbestos-containing material use throughout this entire region is well documented.
