About Niles Plant | Niles, OH
The Niles Plant, operated by Niles Power LLC, sits in Niles, Ohio — Trumbull County, within the Mahoning Valley, one of the most heavily industrialized corridors in American manufacturing history. For decades, this coal-fired generating station supplied power to residential, commercial, and industrial customers across northeastern Ohio.
Like virtually every coal-fired and steam-generating power facility built or substantially expanded during the mid-twentieth century, the Niles Plant reportedly incorporated asbestos-containing materials throughout its original construction and ongoing maintenance operations. Steam-generating facilities of that era — particularly those running high-pressure boilers, steam turbines, and extensive piping networks — ranked among the most asbestos-intensive worksites in American industry.
The Mahoning Valley Industrial Context
The Mahoning Valley carries a well-documented history of industrial asbestos use. Workers who rotated among area plants throughout their careers may have encountered asbestos-containing materials, and other manufacturers at multiple sites, compounding their total cumulative exposure.
This pattern of multi-site exposure is well understood by attorneys who litigate asbestos lawsuits in Missouri and Illinois. Workers who may have been exposed at the Niles Plant and also worked at Missouri facilities along the Mississippi River industrial corridor — including the Labadie Energy Center (Franklin County), the Portage des Sioux Power Plant (St. Charles County), Monsanto facilities in St. Louis County, or Granite City Steel across the river in Madison County, Illinois — may carry cumulative exposures drawn from multiple decades and multiple facilities. That cumulative exposure history is legally relevant in both Missouri and Illinois courts.
Former employees of the Niles Plant, along with contractors and subcontractors who performed work on-site, are among those who may have developed mesothelioma, asbestosis, lung cancer, and pleural disease decades after leaving the facility. Missouri union members — including those affiliated with Heat and Frost Insulators Local 1 (St. Louis), UA Local 562 (pipefitters and steamfitters, St. Louis), and Boilermakers Local 27 (St. Louis) — who traveled to the Niles Plant for contract or outage work may have been exposed to asbestos-containing materials at this facility in addition to Missouri-area sites.
Ohio residents: Your Filing Deadline Is Running Now. If you have been diagnosed with mesothelioma or another asbestos-related disease and worked at the Niles Plant, you have 2 years from your diagnosis date under Ohio Rev. Code § 2305.10. Pending legislation could significantly change your legal options after August 28, 2026. Consult a mesothelioma lawyer in Ohio today.
General Equipment at Niles Plant | Niles, OH
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 Ohio Environmental Protection Agency (Ohio 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 Ohio 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.

The materials documented above (and similar asbestos-containing materials commonly encountered in records of this type) appear in the AsbestosIndex catalog with historical manufacturer and trust-fund information. Click a category to view manufacturers historically associated with that material:
Critical Filing Deadline & Next Steps
Ohio law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (ORC § 2305.10). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (ORC § 2125.02). 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 Ohio 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.
