What Was the Greater Des Moines Power Station?

Facility Overview

The Greater Des Moines Power Station is located in Pleasant Hill, Iowa, a suburban community east of Des Moines in Polk County. The station supplied electricity to central Iowa throughout the twentieth century, reportedly operating from the 1930s through the late 1970s and into the 1980s.

Construction and Operations During Peak Asbestos Use

The facility operated throughout the height of industrial asbestos use in the United States. Like virtually every coal-fired or steam-generating power plant built during this era, the Greater Des Moines Power Station was reportedly constructed using insulation practices that incorporated asbestos-containing materials from major manufacturers, including:

Johns-Manville — asbestos pipe insulation and thermal block
Owens-Illinois — Kaylo insulation products
Armstrong World Industries — gaskets and insulating materials
Combustion Engineering — power generation specifications
W.R. Grace — thermal protection products

Expansion and renovation projects — often performed by rotating crews from Heat and Frost Insulators Local 1 and Plumbers and Pipefitters UA Local 562 — represent the periods when asbestos-containing materials use at power stations is most thoroughly documented in the historical record.

Many of those union members were Iowa and Illinois residents dispatched to Iowa job sites through their home locals. An experienced asbestos cancer lawyer in St. Louis can trace your multi-state exposure history and access applicable bankruptcy trust funds based on the products and manufacturers present at each facility where you worked.

The Mississippi River Industrial Corridor: Why Iowa workers Faced Iowa Exposure

The Greater Des Moines Power Station was part of a broader post-World War II industrial buildout that stretched across the Upper Mississippi River corridor from Iowa through Illinois and Missouri. The same contractors, union locals, and insulation product lines that supplied Missouri and Illinois facilities also supplied Iowa facilities during the peak asbestos era.

Multi-State Union Dispatch: How Iowa workers Reached Iowa Facilities

Missouri and Illinois Union Locals with Iowa Dispatch History:

Heat and Frost Insulators Local 1 (St. Louis, MO) — dispatched regularly to Midwest utility projects including Iowa facilities
Plumbers and Pipefitters UA Local 562 (St. Louis, MO) — sent members statewide and interstate for steam system work
Boilermakers Local 27 (St. Louis, MO) — specialized in high-risk boiler room work across the region
Operating Engineers Local 148 (St. Louis, MO) — provided heavy equipment operators for facility maintenance and renovation

Comparable Missouri and Illinois Facilities with Documented Asbestos-Containing Materials:

Labadie Energy Center (Franklin County, MO)
Portage des Sioux Power Plant (St. Charles County, MO)
Granite City Steel (Madison County, IL)

Missouri and Illinois residents dispatched to Iowa job sites during the peak asbestos era may carry exposure histories spanning multiple states, multiple facilities, and multiple product lines — all of which matter when identifying which bankruptcy trusts apply to your case.

Your Legal Rights: Multi-State Exposure and Iowa Trust Fund Claims

Your legal rights — including access to Iowa’s statute of limitations, Illinois court venues, and asbestos trust fund resources — remain fully intact regardless of where the exposure occurred. An asbestos attorney in Iowa can:

File claims in your home state even though exposure occurred in Iowa
Access all applicable bankruptcy trust funds, including trusts established by manufacturers whose products were reportedly installed at Iowa facilities
Determine your best venue for maximizing compensation across Iowa courts, Illinois federal court, or Iowa litigation
Protect your rights under Iowa’s 2-year asbestos statute of limitations

Why Power Plants Used Asbestos-Containing Materials

The High-Temperature Engineering Problem

Steam-driven power generation requires managing extraordinarily high temperatures and pressures:

Steam temperatures exceeding 1,000 degrees Fahrenheit
Boiler pressures measured in hundreds of pounds per square inch
Miles of high-temperature pipe runs carrying steam throughout the facility
Turbine housings and exhaust systems subject to extreme thermal cycling

No other commercially available insulating material of the twentieth century matched asbestos’s combination of properties: high-temperature resistance, fibrous flexibility, low cost, and long-term durability. Major manufacturers — aware of asbestos’s health hazards — marketed these products aggressively to power utilities while internally suppressing health and safety research. That suppression of evidence is exactly what drives the litigation value of these cases today.

Asbestos-Containing Product Categories in Power Stations

Manufacturers allegedly supplied asbestos-containing materials throughout power generation facilities in the following categories:

Pipe and Thermal Insulation:

Johns-Manville asbestos pipe insulation — 85% magnesia pipe block with asbestos reinforcement
Kaylo insulation (Owens-Illinois) — asbestos pipe sections and block insulation
Woven asbestos rope and packing material — used in pump stuffing boxes, valve stems, and expansion joints

Boiler Systems and Refractory Materials:

Asbestos refractory cement — used for boiler firebox repair and relining
Asbestos-containing boiler block insulation
Asbestos gasket material — compressed asbestos sheet in flanged connections, valve bonnets, and heat exchangers

Structural and Facility Components:

Transite panels and electrical insulating board — asbestos-reinforced panels in control cabinets and electrical enclosures
Asbestos floor tiles and flooring adhesive — in control rooms, offices, and maintenance areas
Asbestos ceiling tiles — in administrative and operational spaces
Fireproofing sprays — applied to structural steel during construction and renovation
Asbestos-cement roofing materials — panels and shingles on facility structures

When Peak Asbestos Use Occurred at Midwest Power Plants

Construction Era (Pre-1940s Through 1960s)

Workers involved in original construction and early expansion projects may have been exposed to asbestos-containing materials during installation of pipe insulation in unventilated mechanical spaces, boiler block insulation in enclosed boiler rooms, fireproofing applications in confined areas, and electrical insulation in switchgear enclosures. Early-era workers received no warning about health hazards and no respiratory protection.

Peak Industrial Use (1940s–1970s): The Critical Exposure Window

The post-World War II industrial expansion marked the period of maximum asbestos-containing materials use in American industry. Iowa power facilities reportedly relied heavily on insulation products supplied by major manufacturers throughout this era.

Mesothelioma carries a latency period of 20 to 50 years between first exposure and diagnosis. Workers first exposed in the 1950s, 1960s, or 1970s are receiving diagnoses today — placing them squarely within Iowa’s 2-year statute of limitations window if they act promptly.

Maintenance and Renovation Era (1960s–1990s)

After asbestos became recognized as hazardous, existing asbestos-containing materials typically remained in place at most power facilities. Maintenance work continued to disturb deteriorated insulation through:

Replacing gaskets and packing material in valve systems
Re-insulating degraded pipe sections
Repairing boilers with asbestos refractory materials
Overhauling turbines and associated systems

Contractor workers and outside tradespeople — including Iowa and Illinois union members dispatched to Iowa job sites — may have faced even higher exposure risks than permanent facility employees. They were often not informed which materials contained asbestos. They worked under compressed schedules in confined spaces where dust concentrations accumulated. That combination — confined space, compressed schedule, no warning — is a recurring pattern that plaintiff-side attorneys have successfully litigated for decades.

Why Asbestos Remained In-Service After Regulations Took Effect

The regulatory response was delayed and incomplete:

1971: OSHA issued its first asbestos occupational exposure standard
1973: EPA established National Emission Standards for Hazardous Air Pollutants (NESHAP)
1989 (later vacated): EPA issued stricter asbestos regulations; the rule was partly overturned in 1991
Post-1970s: Progressively stricter permissible exposure limits (PELs) were phased in

OSHA regulations and EPA standards did not require removal of in-place asbestos-containing materials in good condition. Substantial quantities remained in active service at existing power facilities for decades after these standards took effect. Workers continued to disturb these materials during maintenance, renovation, and capital improvement projects throughout the 1980s and 1990s — long after the manufacturers knew exactly what they were selling and to whom.

High-Risk Occupations and Trades at Power Stations

Asbestos-containing materials exposure at power stations was not confined to one job classification. Power plant work placed multiple trades in direct contact with — or in close proximity to — these materials throughout normal work operations.

Insulators (Heat and Frost Insulators)

Heat and Frost Insulators Local 1 (St. Louis, MO) members may have faced the most direct and concentrated asbestos-containing materials exposure of any trade at power facilities. Local 1 members were regularly dispatched to out-of-state projects throughout the Midwest, including Iowa utility facilities, during the peak asbestos era.

Work activities that allegedly generated significant asbestos fiber release included:

Cutting, sawing, and shaping pipe insulation sections — including Johns-Manville asbestos pipe block and Kaylo products
