What Is Ames GT Power Station?
The Ames GT (Gas Turbine) Power Station in Ames, Iowa, is a municipal electric generation facility operated by Ames Electric Services — the City of Ames’ municipal utility — serving residential, commercial, and industrial customers in Story County, including Iowa State University and the surrounding metropolitan area.
A Facility Built During the Asbestos Era
The Ames municipal electric system expanded substantially during the 1940s through 1970s — precisely when asbestos-containing materials were considered the industry standard, and often the legally required, solution for thermal insulation, fire resistance, and equipment protection in power generation. During this same period, comparable regional power stations along and near the Mississippi River industrial corridor — including the Labadie Energy Center (Ameren UE, Franklin County, Missouri), the Portage des Sioux Power Plant (Ameren UE, St. Charles County, Missouri), and the Granite City Steel complex (Madison County, Illinois) — incorporated extensive asbestos-containing products reportedly manufactured by Johns-Manville, Owens Corning (formerly Owens-Illinois), Eagle-Picher, and W.R. Grace. Manufacturers of these products were internally documenting serious health hazards while withholding that information from the workers installing them.
Iowa workers diagnosed today with mesothelioma or asbestos-related lung cancer who worked at Ames GT or comparable regional facilities have legal rights — but those rights are governed by strict deadlines. Under Iowa Code § 614.1(2), Iowa’s 2-year statute of limitations begins running from your diagnosis date. Active 2026 legislation —
Why Power Stations Used Asbestos-Containing Materials
Power generation facilities became among the most heavily asbestos-laden industrial environments ever built. The reason is straightforward: heat.
Extreme Heat Requires Extreme Insulation
Steam turbines, gas turbines, boilers, and heat exchangers routinely operate at temperatures ranging from several hundred to over 1,000°F. Every component in the heat path requires robust thermal insulation — and from the 1930s through the late 1970s, asbestos-containing products were the industry answer. Manufacturers including Johns-Manville, Owens Corning, and Eagle-Picher aggressively marketed these products throughout Iowa, Iowa, and Illinois:
- Chrysotile (white asbestos) — woven into textiles, mixed into pipe insulation, bound into block and board products manufactured by Johns-Manville and Owens Corning for power generation
- Amosite (brown asbestos) — prized for superior heat resistance in pipe and equipment insulation products manufactured by Eagle-Picher and W.R. Grace
- Crocidolite (blue asbestos) — used in specialty insulation and gaskets manufactured by Owens-Illinois and Johns-Manville; among the most lethal fiber types identified in occupational health research
What the Industry Knew — and Didn’t Tell Workers
- Pre-1970: No federal regulations limited worker exposure to asbestos in industrial facilities. Johns-Manville, Owens Corning, and other manufacturers held internal knowledge of asbestos hazards for decades and continued marketing these products without warning labels throughout Iowa, Iowa, and Illinois.
- 1970–1972: OSHA was established, but enforcement in municipal utilities was inconsistent, and facilities across the region continued operating with legacy asbestos installations.
- 1970s–1980s: Asbestos-containing materials already installed continued to deteriorate and release fibers. Municipal facilities managed these hazards with minimal regulatory guidance.
- NESHAP regulations: EPA required notification and proper abatement before demolition or renovation, generating records now used in litigation in Iowa courtrooms and Illinois venues.
When Asbestos Was Used at Ames GT Power Station
1940s–1950s: Original Construction and Build-Out
Municipal electric utilities across Iowa underwent major capital expansion during and after World War II. Industry standards of the era called for asbestos-containing products from manufacturers including Johns-Manville, Owens-Illinois, and Owens Corning. Workers at Ames GT during this period may have been exposed to asbestos-containing pipe insulation, boiler insulation, turbine insulation, fire-resistant construction board, and asbestos-containing cement products mixed, cut, and applied on-site.
Comparable facilities built during this era in Missouri and Illinois — including early construction at the Labadie Energy Center and Portage des Sioux Power Plant — reportedly relied on identical product types from the same manufacturers.
1960s–1970s: Peak Asbestos Use and Major Overhauls
This period represents peak asbestos content in power generation infrastructure nationwide. Major equipment overhauls, turbine installations, and piping upgrades at facilities like Ames GT allegedly involved extensive use of asbestos-containing products, including:
- Kaylo (Owens Corning / Owens-Illinois) — calcium silicate pipe and block insulation with documented asbestos content, widely identified in Missouri power generation facilities
- Thermobestos — asbestos-containing pipe insulation used across the Midwest
- Johns-Manville asbestos pipe insulation products — multiple product lines distributed throughout Midwest power generation
- Asbestos-containing gaskets and packing materials in valve stems and pump seals, manufactured by Garlock Sealing Technologies and Crane Co.
- Asbestos-containing refractory cements, castables, and insulating blankets
Workers performing maintenance and repair during this period may have been exposed to both freshly applied asbestos-containing materials and deteriorating legacy insulation already in place. Insulators from Heat and Frost Insulators Local 1 (St. Louis) and Local 27 (Kansas City), pipefitters from Plumbers and Pipefitters UA Local 562 (St. Louis), and boilermakers from Boilermakers Local 27 (St. Louis) worked on comparable facilities across the region — including Iowa job sites — during this peak exposure period.
1980s–1990s: Regulatory Recognition and Asbestos Abatement
By the early 1980s, asbestos hazards were well-established in regulatory and scientific literature. Asbestos-containing materials already installed throughout power stations — including products allegedly from Johns-Manville, Owens Corning, W.R. Grace, and Garlock Sealing Technologies — continued to pose exposure hazards, particularly for maintenance workers who routinely disturbed insulation during repair work. Iowa workers who spent earlier career years at comparable Midwest facilities before rotating to Iowa assignments carried cumulative asbestos exposure histories that courts recognize as directly relevant to disease causation.
2000s–Present: Legacy Exposure Concerns
Utility facilities constructed or substantially renovated before 1980 may still contain legacy asbestos-containing materials in place. Workers who disturb insulation, gaskets, or other asbestos-containing components during maintenance or renovation may still encounter these materials today.
If you worked at Ames GT Power Station during any of these periods and have since been diagnosed with mesothelioma, lung cancer, or asbestosis, Iowa filing deadline clock is already running. Iowa law gives you 2 years from diagnosis — and
