About Mullin Creek Generating Station Missouri

Facility Location and Operations

Mullin Creek Generating Station is a natural gas-fired power generation facility in Missouri, operated by Evergy Missouri West Inc., a subsidiary of Evergy Inc. The facility reportedly generates approximately 489.7 megawatts (MW), serving residential and commercial customers across western Missouri. Mullin Creek operates within the same regional network as other major Missouri power facilities with documented histories of asbestos-containing materials use. Related Evergy and predecessor facilities include:

  • Labadie Energy Center (Franklin County, Missouri River)
  • Portage des Sioux Power Plant (St. Charles County, Missouri/Mississippi River confluence)
  • Sioux Energy Center (St. Charles County)
  • Rush Island Energy Center (Jefferson County, Mississippi River)

These facilities were historically connected through shared contractor networks, shared union labor agreements, and centralized product supply chains. A worker whose career spanned multiple Evergy-operated sites may have accumulated significant cumulative asbestos exposure — and that multi-site work history is critical to establishing liability and damages in litigation. The Mississippi River industrial corridor running from the Quad Cities through St. Louis to Cape Girardeau encompasses some of the most heavily industrialized geography in the American Midwest. Missouri and Illinois share this corridor, and skilled trades including insulators, pipefitters, and boilermakers frequently crossed state lines for construction and maintenance projects. Workers employed at Missouri facilities may also have worked at Granite City Steel (Madison County, Illinois), Monsanto chemical operations (St. Louis County and Illinois), and other corridor plants — creating multi-state exposure histories that affect both Missouri and Illinois asbestos lawsuit filing options.

Corporate Ownership and Successor Liability

Liability in asbestos cases runs through corporate predecessors as well as product manufacturers. Multiple entities may bear responsibility depending on when exposure allegedly occurred:

  • Current operator: Evergy Missouri West Inc. - Parent company: Evergy Inc. (formed 2018)
  • **Predecessor entities:
  • Kansas City Power & Light (KCPL)
  • Great Plains Energy Incorporated

Workers allegedly exposed during KCPL operations may hold claims against KCPL, Great Plains Energy, and Evergy under Missouri successor liability doctrine. Corporate restructuring that produced Evergy does not extinguish claims arising from predecessor-era operations — Missouri courts have consistently permitted successor liability arguments in industrial injury cases. This corporate complexity reinforces the importance of contacting an asbestos attorney immediately. The longer you delay, the harder it becomes to locate witnesses, recover records, and establish the chain of corporate liability. Grace** — specialty insulation and fireproofing

Specific product lines reportedly present at comparable Missouri power plants include calcium silicate insulation, pipe covering, and pipe insulations; spray fireproofing sprayed fireproofing; pipe and block insulation electrical insulation; gasket material boiler materials; gaskets and packing; and joint compound wallboard. —

General Equipment at Mullin Creek Generating Station Missouri

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 Missouri Department of Natural Resources (Missouri 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 Missouri 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

Missouri law gives mesothelioma and asbestos-disease claimants 5 years from the date of medical diagnosis to file a personal-injury lawsuit (Mo. Rev. Stat. § 516.120). For wrongful-death claims after an asbestos-related death, the filing window is 3 years from the date of death (Mo. Rev. Stat. § 537.100). 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 Missouri 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.
