About Summit Lake Power Station
Location and Operational History
Summit Lake Power Station is a coal-fired electric generating facility in Iowa that operated as part of the region’s electrical infrastructure throughout much of the twentieth century. It was designed and built during an era when asbestos-containing materials were the industry standard for thermal insulation, fireproofing, and equipment protection at coal-fired steam plants.
Comparable facilities in the Mississippi River industrial corridor include Labadie Energy Center (Franklin County, Missouri), Portage des Sioux Power Plant (St. Charles County, Missouri), Sioux Energy Center (St. Charles County, Missouri), and Rush Island Energy Center (Jefferson County, Missouri), all operated or formerly operated by Ameren UE. Construction methods, materials lists, and exposure patterns at these Missouri facilities closely parallel what workers at Summit Lake may have encountered.
Many union members — particularly insulators, pipefitters, and boilermakers belonging to St. Louis-area locals — reportedly traveled between Iowa and Iowa job sites throughout their careers, accumulating asbestos exposure at multiple facilities along the corridor. This cross-state asbestos exposure history has direct legal significance for your Iowa mesothelioma settlement eligibility and statute of limitations analysis.
The Portage des Sioux plant sits directly on the Missouri bank of the Mississippi River less than thirty miles from the Iowa border. Workers whose trades took them to both Portage des Sioux and Summit Lake may carry asbestos exposure histories spanning two states — a factor that significantly affects venue selection and compensation strategy under Iowa asbestos law.
Granite City Steel in Madison County, Illinois, and the former Monsanto Chemical complex in St. Louis County, Missouri, represent additional facilities in the corridor where many of the same union locals sent their members, further expanding the potential asbestos exposure record for any individual worker.

Four Phases of Asbestos-Containing Materials Use at Power Stations
Power stations went through distinct phases of asbestos exposure risk, each carrying its own exposure profile:
Initial construction (roughly 1940s–1970s): Asbestos-containing products are alleged to have been installed throughout boilers, pipe systems, structural steel, flooring, and electrical equipment at facilities like Summit Lake.
Operational maintenance (continuing through facility life): Workers may have been exposed when they repaired, removed, and replaced insulation and equipment components — often without respirators or hazard warnings about asbestos dangers.
Renovation and upgrade cycles (periodic facility updates): Modernization projects are alleged to have disturbed asbestos-containing materials already in place for decades. Friable insulation may have released fibers when cut, abraded, or jostled during updates.
Decommissioning and demolition (end-of-life facility closure): Previously undisturbed asbestos-containing materials were reportedly released in concentrated quantities as structures were torn down or gutted for salvage.
Utility facilities routinely operated for fifty years or more. Workers across multiple generations may have encountered asbestos-containing materials with no warning labels, no hazard identification, and no protective equipment requirements — a pattern extensively documented in litigation involving Iowa facilities.
General Equipment at Summit Lake Power Station
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
- 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 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.
