Facility Overview and History

Location and Service Area

Lime Creek Power Station sits along the Lime Creek watershed near Mason City, Iowa, in Cerro Gordo County. The facility reportedly operated as part of the electric power generation infrastructure serving north-central Iowa for decades — in a region whose industrial development closely mirrors the Mississippi River industrial corridor shared by Missouri and Illinois, where comparable generating stations including Ameren UE’s Labadie Energy Center (Franklin County, MO), Portage des Sioux Power Plant (St. Charles County, MO), Rush Island Energy Center (Jefferson County, MO), and Granite City Steel (Madison County, IL) built out intensive industrial capacity across the same mid-twentieth century decades.

That corridor context matters for workers and their families: skilled-trades workers routinely followed construction and maintenance contracts across state lines — from Mason City south through Iowa and into Iowa and Illinois. A worker’s full asbestos exposure history may span multiple facilities and multiple states. **For those whose exposure history includes Iowa facilities, the August 28, 2026 deadline created by

Historical Development and Industrial Context

Mason City and Cerro Gordo County built out significant industrial capacity during the twentieth century: agricultural processing, cement manufacturing, and electric power generation. Lime Creek Power Station, like comparable Missouri power plants such as Portage des Sioux Power Plant and Labadie Energy Center, reportedly depended on heat-resistant and insulating materials throughout construction and operation — many of which are alleged to have contained asbestos-containing materials under the construction and maintenance standards of the era.

The broader regional pattern is legally significant: Missouri facilities such as Labadie Energy Center and Portage des Sioux Power Plant reportedly used products from the same manufacturers — Johns-Manville, Owens-Illinois, Armstrong World Industries, Combustion Engineering — under the same industry specifications. Workers who moved between Iowa and Missouri or Illinois facilities, or who worked for contractors active across the region, may have accumulated asbestos exposure from multiple facilities and multiple product sources. **Any exposure history that touches Missouri facilities is now subject to time pressures created by

Workforce and Exposure Population

Over its operational lifetime, the plant reportedly employed or contracted workers across multiple skilled trades:

  • Boilermakers (potentially affiliated with Boilermakers Local 27, St. Louis, MO, on regional contracts)
  • Pipefitters and steamfitters (potentially affiliated with Heat and Frost Insulators Local 1, St. Louis, MO; UA Local 562, St. Louis, MO; or regional locals)
  • Insulation workers (potentially affiliated with Heat and Frost Insulators Local 1 or Local 27, Kansas City, MO)
  • Electricians
  • Millwrights and machinists
  • Maintenance workers
  • Plant operators
  • Welders
  • Laborers

Those workers — and family members who laundered their work clothing — may have faced asbestos exposure risks that were never adequately disclosed to them. Workers with exposure across multiple Iowa facilities should understand that their full exposure history is legally relevant — and that time to act before the August 28, 2026 deadline is limited.

Why Asbestos Was Used in Power Generation

The Physics of Steam Power Generation

Steam-driven power generation operates on extreme thermal differentials. Boilers at facilities like Lime Creek Power Station reportedly generated steam at temperatures exceeding 1,000°F and pressures in the hundreds of pounds per square inch. Equipment required insulation that could retain heat to maximize thermodynamic efficiency, protect workers from burn injuries, prevent energy loss across long pipe runs, and withstand temperature cycling through repeated startups and shutdowns.

Why Manufacturers Chose Asbestos-Containing Materials

Asbestos-containing materials were the dominant solution to these engineering requirements for most of the twentieth century. The mineral offered heat stability, flame and chemical resistance, low cost, and straightforward installation. Major manufacturers — including Johns-Manville, Owens-Corning, Armstrong World Industries, Combustion Engineering, Celotex, W.R. Grace, Georgia-Pacific, and Eagle-Picher — aggressively marketed asbestos-containing insulation, gaskets, and fireproofing compounds to the power generation sector. Their products are reported to have been among the primary materials installed at Lime Creek Power Station and comparable facilities including Labadie Energy Center, Portage des Sioux Power Plant, and Granite City Steel.

What Manufacturers Knew — And Concealed

Internal documents produced through decades of asbestos litigation — including cases filed in Polk County District Court and Madison County, Illinois Circuit Court — show that major manufacturers allegedly possessed internal research confirming that asbestos fiber inhalation caused serious and fatal diseases. Despite that knowledge, they are alleged to have continued marketing these products without adequate warnings to the workers who handled them every day.

Workers diagnosed with mesothelioma or asbestos-related disease as a result of these alleged concealment practices may have legal rights under Iowa law — but those rights must be exercised before statutory deadlines expire.

Timeline: When Asbestos-Containing Materials Were Present

The Peak Exposure Era: 1940s Through Late 1970s

Power generation facilities like Lime Creek were most intensively constructed, expanded, and renovated from approximately 1940 through the mid-1970s — precisely when asbestos use in industrial applications peaked. Workers employed at or contracted to Lime Creek Power Station during this period may have encountered the highest concentrations of asbestos-containing materials.

That same construction timeline applies to Missouri corridor facilities: Portage des Sioux Power Plant came online in the early 1950s, Labadie Energy Center began construction in the 1960s, and Granite City Steel expanded repeatedly through the same decades — all under identical industry specifications for asbestos-containing materials procurement and installation.

Workers who were active in these trades during the peak exposure era are now in their 70s, 80s, and beyond — precisely the age range when asbestos-related diseases emerge after decades of latency. A mesothelioma diagnosis may feel sudden. It has been building for 30 or 40 years. The 5-year statute of limitations under Iowa Code § 614.1(2) runs from diagnosis, not from exposure — meaning the window to act opens the day you receive your diagnosis, and it does not stay open indefinitely.

Pre-1970s Construction and Expansion

During the post-World War II economic expansion, power utilities across the Midwest undertook large construction and capacity expansion projects. Those projects reportedly required substantial quantities of asbestos-containing insulation, fireproofing, and construction materials manufactured by Johns-Manville, Owens-Corning, Armstrong World Industries, Combustion Engineering, and Georgia-Pacific. Workers who participated in original construction or major expansions of Lime Creek Power Station during this era may have been exposed to asbestos-containing materials in their most friable state — when fibers release most readily into the breathing zone.

Contractors who moved between Lime Creek and Missouri or Illinois facilities during the same period — including work at Monsanto’s St. Louis area operations or Granite City Steel — may carry cumulative asbestos exposure histories spanning multiple states and multiple product sources. Those multi-state exposure histories can strengthen legal claims, and they make prompt consultation with a Iowa asbestos attorney all the more important.

1970s Maintenance and Repair Operations

Routine maintenance, repair, and renovation at power stations continued to disturb existing asbestos-containing installations even as asbestos hazards became more widely known. Workers performing the following tasks during the 1970s may have been exposed:

  • Boiler maintenance and re-tubing
  • Re-insulation of pipe systems using products such as Kaylo, Thermobestos, Aircell, and Monokote (manufactured by Johns-Manville and competitors)
  • Equipment overhauls and refurbishment
  • Removal of degraded or damaged asbestos-containing insulation
  • Replacement of asbestos-containing gaskets and packing materials from manufacturers including Garlock Sealing Technologies

Asbestos-containing materials that degraded over time became increasingly friable — more easily crumbled, more likely to release fibers into the breathing zone of anyone working nearby.

The Regulatory Transition: 1970s–1980s

OSHA and EPA issued asbestos-specific regulations beginning in the 1970s — including the OSHA asbestos standard promulgated in 1972, EPA asbestos regulations throughout the decade, and NESHAP (National Emission Standards for Hazardous Air Pollutants) asbestos requirements. Regulatory implementation at specific facilities was uneven, however. Workers at Iowa and Midwest power stations may have continued to face exposure risks well into the 1980s, particularly during renovation and demolition activities where existing asbestos-containing materials were disturbed.

Occupational Groups at High Risk

Boilermakers and High-Heat Equipment Workers

Boilermakers who worked on boiler installation, repair, and maintenance at Lime Creek Power Station may have been exposed to asbestos-containing insulation, refractory materials, and packing compounds used in boiler systems. Workers affiliated with Boilermakers Local 27 (St. Louis, MO) or other regional locals on construction and maintenance contracts may have performed similar work at comparable Missouri power plants including Labadie Energy Center and Portage des Sioux Power Plant.

Exposure risk was reportedly highest during:

  • Original boiler installation (1940s–1960s)
  • Major re-tubing operations
  • Removal and replacement of asbestos-containing insulation
  • Repair of degraded gaskets and packing materials

Insulators and Heat/Frost Insulators

Workers affiliated with Heat and Frost Insulators Local 1 (St. Louis, MO), Heat and Frost Insulators Local 27 (Kansas City, MO), or UA Local 562 (St. Louis, MO) who performed pipe insulation, equipment insulation, and fireproofing work may have encountered concentrated levels of airborne asbestos fibers — particularly when cutting, trimming, or removing pre-formed pipe insulation products manufactured by Johns-Manville, Owens-Corning, and Armstrong World Industries.
