About Fair Station | Montpelier, IA | Central Iowa

Engineering Requirements of Coal-Fired Power Plants

The reported use of asbestos-containing materials at Fair Station reflects the engineering demands of steam-electric power generation:

  • Extreme heat — steam temperatures exceeding 750°F and boiler temperatures exceeding 1,000°F
  • High-pressure systems — steam operating at hundreds of pounds per square inch
  • Thermal cycling stress — repeated expansion and contraction of metal components
  • Corrosive environments — moisture, sulfur compounds from coal combustion, and chemical treatments

Before the 1970s, no commercially available material matched asbestos across all of these requirements simultaneously:

  • Exceptional heat resistance
  • High tensile strength
  • Chemical stability
  • Low cost
  • Ease of fabrication

Industry-Wide Adoption by Major Asbestos Manufacturers

By the 1930s, asbestos insulation had become effectively universal in power plant construction. Engineering specifications routinely called for asbestos pipe covering, block insulation, cement, and gaskets as standard components. The same asbestos-containing products marketed and sold to facilities throughout the Mississippi River industrial corridor — including Missouri power plants like Labadie and Portage des Sioux — were marketed and sold to facilities like Fair Station under the same product names by the same manufacturer representatives.

Major manufacturers supplied asbestos-containing products specifically marketed to power generation facilities, and workers at Fair Station may have been exposed to materials from some or all of the following suppliers:

  • Corporation** — dominant supplier of pipe insulation and thermal products
  • — producer of calcium silicate pipe insulation, a widely used sectional covering product in U.S. power plants
  • — manufacturer of thermal insulation and building products
  • ceiling tile — producer of asbestos-containing insulation board and thermal materials
  • — supplier of high-temperature gasket and packing materials
  • — integrated boiler and equipment supplier with asbestos-containing components
  • — producer of asbestos-containing insulating coatings and castables
  • gaskets and packing — major manufacturer of asbestos-containing gasket and packing rope products
  • — supplier of gypsum wallboard products with asbestos-containing fire-stopping compounds
  • — manufacturer of valves and fittings with asbestos-containing thermal insulation and packing materials

Known Dangers, Concealed from Workers

Internal corporate documents produced in litigation revealed that manufacturers including were aware of asbestos’s carcinogenic properties as early as the 1930s and 1940s, yet continued marketing asbestos-containing products without adequate health warnings to workers or plant operators. That deliberate concealment remains central to toxic tort claims and mesothelioma litigation today — including cases filed in Polk County District Court, Madison County, Illinois, and St. Clair County, Illinois, all of which have active asbestos dockets drawing on claims from workers throughout the Mississippi River industrial corridor., a major supplier of calcium silicate pipe insulation, and similarly had access to medical literature warning of asbestos’s dangers during the period they marketed these products to power plants. Their failure to warn plant maintenance workers forms the basis for substantial pending litigation in Iowa and Illinois courts.

Multiple Trades Faced Asbestos Exposure Risks

Asbestos exposure at steam-electric facilities was not limited to any single job classification. Workers across many trades shared the same spaces. Asbestos fibers released by one trade’s activities became airborne hazards for everyone in the vicinity. Many workers who may have been exposed at Fair Station were members of Missouri and Illinois union locals dispatched to Iowa job sites throughout their careers.

Heat and Frost Insulators: Direct Asbestos Exposure

Members of the Heat and Frost Insulators and Allied Workers — including Local 1 (St. Louis, Missouri) and Local 27 (Kansas City, Missouri) — faced among the most direct potential exposure when dispatched to Fair Station and comparable facilities along the Mississippi River industrial corridor:

  • Reportedly mixing and applying asbestos-containing insulating cement to pipe surfaces
  • Cutting and fitting asbestos-containing pipe covering to equipment, including calcium silicate pipe insulation and comparable sectional products
  • Removing deteriorated asbestos-containing insulation during high-release “rip-out” operations
  • Applying asbestos-containing block insulation to boiler surfaces
  • Fabricating custom insulation from asbestos-containing cloth and felt
  • Handling asbestos-containing rope and cord packing materials

Studies of insulator union populations document elevated rates of mesothelioma, asbestosis, and lung cancer compared to the general population. Heat and Frost Insulators Local 1 in St. Louis has historically served workers dispatched to facilities throughout Iowa, Illinois, and neighboring states including Iowa — meaning members of Local 1 may have worked at Fair Station during major construction, overhaul, or maintenance periods.

Pipefitters and Steamfitters: Gasket and Packing Work

Members of the United Association of Plumbers and Pipefitters (UA) — including Local 562 (St. Louis, Missouri) and Local 268 (Kansas City, Missouri) — are reported to have worked on steam, feedwater, condensate, and cooling systems central to plant operation. UA Local 562, based in St. Louis, is one of the largest and most historically active pipefitter locals in the Mississippi River region, with members dispatched to power plants and industrial facilities across Iowa, Illinois, and Iowa:

  • Gasket work: Reportedly scraping and replacing asbestos-containing compressed gaskets — manufactured by gaskets and packing and comparable suppliers — on flanged joints, valve bonnets, and connections throughout the plant
  • Valve packing: Removing and repacking valves with asbestos-containing packing rope allegedly produced by gaskets and packing and
  • Proximity exposure: Working alongside insulators who were disturbing asbestos-containing products including calcium silicate pipe insulation, Thermobestos, pipe insulation, and comparable materials

Gasket removal carries particular significance in asbestos litigation: studies show scraping old asbestos-containing gaskets from flanges can generate fiber concentrations that may have substantially exceeded safe exposure levels.

Boilermakers: Confined Space and Refractory Exposure

Members of the International Brotherhood of Boilermakers — including Local 27 (St. Louis, Missouri) — maintained boilers, pressure vessels, and related components at power generating facilities throughout the region. Boilermakers Local 27 has represented workers at Missouri River and Mississippi River corridor power plants for decades, and members are reported to have been dispatched to Iowa facilities during major outages and construction projects:

  • Reportedly working inside boiler fireboxes allegedly lined with asbestos-containing refractory cement, including products supplied by and
  • Repairing tube sheets, drums, and headers with asbestos-containing materials
  • Replacing access door and handhole gaskets on pressure parts with asbestos-containing products
  • Working in confined spaces where asbestos-containing insulation had allegedly deteriorated and become friable

Confined-space work during boiler outages is reported to have created elevated airborne fiber concentrations due to limited ventilation. The same exposure patterns documented for Boilermakers Local 27 members working at Missouri facilities like Labadie and Portage des Sioux are alleged to apply equally to members dispatched to facilities like Fair Station.

Electricians: Switchgear and Wiring Insulation

Members of the International Brotherhood of Electrical Workers (IBEW) worked on switchgear, controls, wiring, and instrumentation systems throughout the plant:

  • Switchgear insulation: Vintage switchgear may have contained asbestos-containing arc-quenching liners and insulating sheets allegedly manufactured by and comparable suppliers
  • High-temperature wiring: Specialized electrical wiring in power plant environments may have incorporated asbestos-containing insulation on conductors and conduit seals
  • **Proximity

General Equipment at Fair Station | Montpelier, IA | Central Iowa

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 Iowa Department of Natural Resources (Iowa DNR) 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 Iowa DNR 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

Iowa law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (Iowa Code § 614.1(2A)). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (Iowa Code § 614.1(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

  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 Iowa 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.
