Legally Reviewed by Michael Throneberry, Attorney. President, National Trial Lawyers Asbestos & Mesothelioma Bar (2025 and 2026).
If you worked at a Kansas City plant, refinery, power station, or federal complex before the 1980s, asbestos may have been part of the job. Mesothelioma often appears decades after the exposure that causes it, so the work history that matters may be 40 or 50 years old. This page lists the metro sites where the record is strongest: government environmental files, Missouri state boiler inspection records, and the approved-site lists that asbestos bankruptcy trusts use to pay claims.
Throneberry Law Group keeps its registered primary office in downtown Kansas City, and attorney Michael Throneberry started his career litigating in Missouri courts. He lost his own father-in-law to mesothelioma, so we handle every family’s case personally and never pass it down a line. Our Kansas City mesothelioma lawyer page explains how we take a case from the first call to a recovery.
Federal Plants Where Government Records Name Asbestos
Three large federal sites in the metro have government environmental records that list asbestos by name. That is rarer than people expect, and it matters when we build a claim.
Lake City Army Ammunition Plant in Independence
Remington Arms opened the plant in 1941 to make and test small-caliber ammunition, and it sits on 3,935 acres at Highways 7 and 78 in eastern Jackson County. The plant was placed on the Superfund National Priorities List in 1987. The Missouri Department of Natural Resources lists asbestos siding among the contaminants at the site, and asbestos trusts also list Lake City as an approved exposure site. Our Lake City Army Ammunition Plant page covers the plant in more detail, including claims for veterans and civilian workers.
Bannister Federal Complex in South Kansas City
The complex at 1500 to 2000 E. Bannister Road was built in 1942 to make airplane engines for the Navy. From 1949 it housed the Kansas City Plant, which made non-nuclear parts for nuclear weapons. According to the Missouri Department of Natural Resources, building materials containing asbestos were located throughout the facility buildings. Bendix Corporation’s Kansas City location appears on the approved-site lists of six asbestos trusts. Our Honeywell and Bendix page explains how those companies’ asbestos liability passed to Honeywell.
Sunflower Army Ammunition Plant Near De Soto, Kansas
Sunflower covers about 9,065 acres in the northwest corner of Johnson County. It made nitrocellulose, nitroglycerin, and propellants from 1942 to 1971, then acids and nitroguanidine until 1992, with Hercules as the operator. A July 2026 Kansas Department of Health and Environment report lists asbestos-containing materials at the site and records that 53.51 tons of coated concrete were removed and disposed of as asbestos-containing material in 2025. Sunflower and Hercules Powder Company at De Soto both appear on asbestos trust lists.
Refineries, Power Stations, and Heavy Industry
The trust lists show the heaviest concentration of approved sites in fuel, power, and manufacturing. These are the metro sites that the most trusts recognize.
Refineries and Power Plants
The Sugar Creek refinery, built by Standard Oil of Indiana in 1904 and shut down by Amoco in 1982, covered 450 acres along the Missouri River, according to the Missouri Department of Natural Resources. Eleven asbestos trusts list it, more than any other Kansas City site in our review. The Phillips refinery in Kansas City, Kansas is listed by six. Among power stations, trusts list Hawthorn Station, Grand Avenue Station, Sibley Station, the Blue Valley plant in Independence, and the Board of Public Utilities’ Kaw and Quindaro plants. Missouri state boiler inspection records show water-tube power boilers at Sibley built in 1959 and 1960. Our power plant and refinery pages explain how those workplaces exposed workers.
Auto Assembly, Steel, and Manufacturing
Trusts list the Ford Claycomo plant, and Missouri state boiler inspection records show two Wickes water-tube power boilers built in 1951 in its powerhouse. General Motors plants on both sides of the line appear as well, including the Chevrolet Leeds assembly plant. Other listed sites include Armco and Sheffield Steel, Procter & Gamble in Kansas City, Kansas, Corn Products in North Kansas City, Owens Corning, Colgate, and the Swift, Armour, Cudahy, and Wilson packing houses. A circa 1930 aerial photograph in the Kansas City Public Library’s collection on the West Bottoms packing houses shows the Cudahy and Swift plants and the Kansas City Stockyards along the Kansas River, and both packers and the stockyards company appear on trust lists.
Jobs That Carried the Most Risk
Trust listings tell us where asbestos was, but the job tells us who breathed it. The trades below are the ones we see most often in Kansas City work histories:
- Boiler and power plant workers: Operators, boilermakers, and outage crews at the metro’s generating stations and plant powerhouses.
- Refinery workers: Pipefitters, insulators, and maintenance crews at Sugar Creek and the Kansas City, Kansas refineries.
- Ammunition and federal plant workers: Production and maintenance staff at Lake City, Sunflower, and the Bannister complex.
- Assembly and plant maintenance workers: Millwrights, electricians, and mechanics at the Ford, General Motors, and steel plants.
- Building trades: Insulators, plasterers, and carpenters who built or renovated hospitals, schools, and offices across the metro.
If your job is not on this list, it may still matter. Family members who washed a worker’s clothes can also develop mesothelioma, and that take-home exposure can support a claim.
Where Your Case Is Filed Can Depend on the Site
Many Kansas City careers crossed the state line, and Missouri and Kansas set different filing deadlines. The site where you were exposed, where you lived, and which companies were involved can all change which state’s law applies. Our page on Missouri and Kansas mesothelioma claims walks through the differences.
Common Questions About Kansas City Asbestos Exposure
Here are direct answers to the two questions families ask us most about these sites.
What Kansas City Job Sites Are Most Linked to Asbestos Exposure?
The Kansas City sites with the strongest records are the Lake City Army Ammunition Plant, the Bannister Federal Complex, and the Sunflower Army Ammunition Plant, where government environmental files list asbestos by name. The Sugar Creek refinery appears on more asbestos trust approved-site lists than any other site in the metro, and Procter & Gamble in Kansas City, Kansas, Armco and Sheffield Steel, Bendix, and Hawthorn Station are among the most widely listed. Ford Claycomo, General Motors, the packing houses, and many hospitals and schools are listed too. If you worked at one of these sites, or lived with someone who did, that history may support a claim. We review work histories at no cost in a free, no-obligation consultation.
Does It Matter Whether My Exposure Happened in Missouri or Kansas?
Yes, it can matter a great deal. Missouri generally allows five years to file a personal injury claim under RSMo 516.120. Kansas generally allows two years under K.S.A. 60-513, starting when the injury becomes reasonably ascertainable. The same work history can carry very different deadlines depending on where the exposure happened, where you lived, and which state’s law applies. Many Kansas City careers crossed the state line, so we look at every worksite before advising on where to file. We sort out which state’s law fits your case as part of a free, no-obligation case review.
Talk With the Kansas City Asbestos Lawyers at Throneberry Law Group
A list of sites is only a starting point. What wins a case is tying your own work history to a specific plant, product, and company, and that takes digging through decades of records. We do that work for families across the Kansas City metro, on both sides of the state line, and we can help in Spanish.
You pay nothing unless we recover money for you, and the first conversation costs nothing. If you worked at any of the sites on this page, or a family member did, tell us about the work history through our contact form.
