About Hanging Rock Energy Facility
Facility Location and Regional Industrial Context
The Hanging Rock Energy Facility sits in Ironton, Ohio, along the Ohio River in Lawrence County. This region has operated as a heavy industrial corridor since the mid-1800s, and workers here often held jobs at multiple facilities across Ohio, Kentucky, and West Virginia — and frequently across the Mississippi River industrial corridor connecting southwest Ohio and Lawrence County to Missouri and Illinois — throughout their careers.
Key historical markers:
- Mid-19th century: Lawrence County ranked among the nation’s most productive iron-producing centers
- Late 19th–20th century: Steel manufacturing, coke production, and energy generation became the dominant industries
- Tri-state and Mississippi River industrial corridor: Ironton and surrounding areas in Ohio, Kentucky, and West Virginia formed a connected industrial ecosystem that extended westward through the Mississippi River corridor into Illinois and Missouri; workers regularly moved between power plants, coke ovens, chemical facilities, and manufacturing operations on both sides of the Mississippi
Hanging Rock operated as an energy generation facility serving regional power demand. Power plants of this type reportedly contained asbestos-containing materials from major manufacturers throughout the 20th century.
Connected Facilities and Cumulative Exposure Along the Mississippi River Industrial Corridor
Workers in Lawrence County and the tri-state region often accumulated asbestos exposure across multiple job sites. The Mississippi River industrial corridor connecting southern Ohio to Missouri and Illinois created a web of shared worksites, shared employers, and shared asbestos-containing products.
Workers at Hanging Rock and similar regional facilities may have been exposed to asbestos-containing materials at connected Missouri and Illinois worksites, including:
- Energy generation facilities such as AmerenUE’s Labadie Power Plant in Franklin County, Missouri, and Portage des Sioux Power Plant in St. Charles County, Missouri — both coal-fired facilities where asbestos-containing materials were reportedly used extensively in boiler, turbine, and pipe insulation systems
- Steel manufacturing operations, including Granite City Steel (later U.S. Steel) in Granite City, Illinois, where asbestos-containing materials were allegedly present in coke ovens, blast furnaces, and steelmaking equipment, and Laclede Steel in Alton, Illinois
- Petrochemical and refinery operations, including Shell Oil’s Roxana Refinery and Clark Refinery in Wood River, Illinois, and Monsanto Chemical operations in Sauget, Illinois, and St. Louis, Missouri, where workers may have been exposed to asbestos-containing pipe insulation, boiler lagging, and gasket materials
- Other manufacturing facilities, including Alton Box Board in Alton, Illinois
Workers at these facilities may have been exposed to asbestos-containing materials from major manufacturers: , gaskets and packing, ceiling tile.
For workers who spent portions of their careers at Ohio or Illinois facilities alongside Hanging Rock work history, this cross-site exposure documentation can support claims filed in Ohio courts and may significantly affect venue selection and total compensation recovery.**
Under Ohio Rev. Code § 2305.10, Ohio’s statute of limitations for mesothelioma and asbestos-related disease claims is 2 years from the date of diagnosis — not the date of last exposure. If you were recently diagnosed, your clock is already running.Call an experienced Ohio asbestos attorney now to:

Do not wait. The deadline is real. Legislative changes could reshape your case.
Union Records as Exposure Evidence
Many workers at Hanging Rock and related regional facilities belonged to skilled trades unions. For Missouri and Illinois workers — including those who traveled to Ohio job sites or who worked at Missouri and Illinois facilities using identical asbestos-containing products — union locals maintained membership, apprenticeship, and job assignment records that can be critical exposure evidence:
- Heat and Frost Insulators Local 1 (St. Louis, MO) — insulation mechanics who worked at power plants, refineries, and chemical facilities throughout Ohio and southwestern Illinois
- Boilermakers Local 27 (St. Louis, MO) — boilermaker-welders whose work on steam generation systems placed them in direct contact with asbestos-containing boiler lagging, refractory materials, and gaskets
- Plumbers and Pipefitters UA Local 562 (St. Louis, MO) — pipefitters who installed and maintained insulated piping systems at power plants and industrial facilities along the Mississippi River corridor
- Heat and Frost Insulators Local 27 (Kansas City, MO)
- Plumbers and Pipefitters UA Local 268 (Kansas City, MO)
Union membership records, apprenticeship training documentation, and job assignment cards can establish work location, duration, and job duties — three factors that directly support proving asbestos exposure. For Ohio residents, these records are particularly valuable because they may support claims filed in Cuyahoga County Common Pleas, which has established asbestos litigation procedures and judges experienced with occupational exposure cases.

It resists corrosion from acids and alkalis, does not conduct electricity, and absorbs industrial noise. These properties made it the default material choice throughout power plant infrastructure for most of the 20th century.
The same manufacturers who supplied asbestos-containing materials to facilities like Hanging Rock Energy also supplied identical or functionally equivalent products to Labadie Power Plant, Portage des Sioux Power Plant, Monsanto Chemical facilities in Missouri, and Granite City Steel in Illinois. Workers who moved between these facilities may have encountered the same branded products from the same manufacturers at job site after job site.
Where Asbestos-Containing Materials Were Reportedly Used
Workers at Hanging Rock Energy may have been exposed to asbestos-containing materials in the following systems and locations:
Boiler and Steam Systems
- High-pressure steam turbine insulation allegedly containing asbestos fiber
- Boiler lagging and block insulation
- Steam line pipe covering and wrapping
- Boiler refractory linings and fireproof cement
- Products allegedly, and gaskets and packing
Turbine Systems
- Thermal insulation on turbine bodies and casings
- Insulation on steam inlet and exhaust connections
- Asbestos-containing expansion joints and flexible connectors
- Insulation blankets and lagging on turbine inlet valves
- Products reportedly including calcium silicate pipe insulation and Thermobestos brand materials
Electrical and Control Systems
- Electrical insulation in switchgear and bus ducts
- Asbestos-containing insulation in circuit breakers and arc chutes
- Cable tray insulation and electrical tape
- Panel board backing materials allegedly and other suppliers
Structural and Fireproofing
- Spray-applied asbestos fireproofing on structural steel
- Asbestos-containing drywall and ceiling tile, including Gold Bond and brand materials
- Asbestos-containing joint compound
General Equipment at Hanging Rock Energy Facility
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.

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.
