The Festus Facility: History and Documented Asbestos Risk

Background and Corporate History

The Buzzi Unicem USA cement plant in Festus, Missouri sits in Jefferson County along the Mississippi River industrial corridor — one of the most heavily industrialized stretches in the Midwest. The facility currently operates as a subsidiary of Italian multinational Buzzi Unicem S.p.A., but it has changed hands and names over the decades.

Missouri DNR NESHAP regulatory records reference a “Former LaRoche Facility” associated with this site (NESHAP abatement notification ID: A9012-2025). Workers and retirees may know the plant under earlier corporate names. That long operational history is precisely why asbestos exposure risk here spans multiple generations of workers — asbestos-containing materials installed decades ago do not disappear when a company changes its name.

Why Cement Plants Were Asbestos-Intensive Environments

Cement manufacturing is among the most asbestos-intensive industrial processes in American history, particularly at facilities built or expanded between 1930 and 1980. Rotary kilns operate at temperatures exceeding 2,700°F, and that heat demands insulation. For most of the twentieth century, that insulation was asbestos.

Workers at facilities of this type may have encountered asbestos-containing materials in applications including:

• Kiln, preheater, pipe, and duct insulation — products from manufacturers including Johns-Manville and Owens-Corning
• Gaskets and packing on pumps, valves, and flanges — products reportedly supplied by Garlock Sealing Technologies and Crane Company
• Structural fireproofing — materials potentially supplied by W.R. Grace & Company
• Floor tile in control rooms and offices — products potentially manufactured by Armstrong World Industries
• Roofing materials across large industrial structures
• Transite board (asbestos-cement composite) used for partitions and vent ducts
• Window and expansion joint caulking

From the 1930s through the late 1970s — and into the 1980s at many facilities — these applications relied on asbestos-containing materials because asbestos was inexpensive, fire-resistant, and the established industry standard. The manufacturers knew about the health risks. They chose profit over disclosure. That decision is why mesothelioma cases exist today.

MDNR NESHAP Records: What the Public Documents Show

Under the federal Clean Air Act (40 CFR Part 61, Subpart M), facility owners must notify state environmental agencies before disturbing asbestos-containing materials during renovation or demolition. The Missouri Department of Natural Resources maintains these notifications as public records — and they are among the most powerful pieces of evidence in asbestos litigation.

The following MDNR NESHAP notifications document asbestos-containing materials allegedly present at the Buzzi Unicem USA Festus plant:

NESHAP Notification ID: A6640-2015

Friable thermal system insulation removal in 2015 confirms that asbestos-containing materials were allegedly present in this facility’s active infrastructure decades after peak industrial asbestos use — meaning workers who spent careers here may have encountered it long after regulators began restricting the material elsewhere.

NESHAP Notification ID: A6730-2015

A second renovation notification within the same calendar year confirms that friable thermal system insulation was allegedly identified across multiple areas of the facility — not an isolated pocket, but a recurring condition throughout the plant’s infrastructure.

NESHAP Notification ID: A6852-2015

Three renovation notifications in a single calendar year — February, July, and December 2015 — document an extensive thermal insulation infrastructure that allegedly contained asbestos-containing materials throughout the plant. This is not incidental contamination. This is a facility-wide pattern.

NESHAP Notification ID: A9012-2025 — Largest Documented ACM Removal at This Site

Read that number carefully: over 14,600 square feet of friable asbestos-containing materials allegedly removed from a single structure during demolition in 2025 (documented in MDNR NESHAP abatement records). These were not materials sitting unused in a storage room — they were insulation systems integrated into an operational industrial structure throughout its working life. Workers in those buildings may have been exposed to airborne asbestos fibers during ordinary daily operations, not only during demolition or renovation.

ACM Types Documented at the Festus Plant

Friable asbestos-containing materials release airborne fibers when crumbled, cut, or disturbed. Those fibers are inhaled into lung tissue where they cause mesothelioma and asbestosis — diseases that often do not appear for twenty to fifty years after exposure. The latency period is why workers who retired years ago are only now receiving diagnoses.

Who Was at Risk: High-Exposure Trades at This Facility

Mesothelioma is caused by inhaling microscopic asbestos fibers over time. At a large cement plant like the Festus facility, multiple trades may have encountered asbestos-containing materials as part of routine daily work. The fact that you did not work directly with insulation does not mean you were not exposed — bystander exposure is a recognized and litigated cause of mesothelioma.

Trades with Highest Documented Exposure Risk

Heat and Frost Insulators

Workers — including members of Heat and Frost Insulators Local 1 (St. Louis) or Local 27 (Kansas City) — who worked at the Festus plant may have installed, repaired, or removed thermal system insulation on kilns, pipes, boilers, and process equipment. Insulation work generates the highest concentrations of airborne asbestos fiber of any trade. Insulators appear in mesothelioma case records at higher rates than nearly any other trade classification in the United States, and the NESHAP records here document the type of insulation work they would have performed.

Pipefitters and Plumbers

Members of UA Local 562 (St. Louis) or UA Local 268 who worked at industrial facilities in this region may have encountered asbestos-containing pipe insulation, gaskets, and packing materials throughout the plant’s piping systems. Products reportedly supplied by Garlock Sealing Technologies and Crane Company were among those allegedly used at facilities of this type. Cutting insulated pipe runs allegedly released friable fiber directly into the breathing zone. Gasket removal and replacement created direct hand contact with asbestos-containing materials — and hands covered in asbestos dust go home, contaminating cars and family members.

Boilermakers

Boilers, pressure vessels, and high-temperature process equipment were insulated with asbestos-containing materials from manufacturers including Johns-Manville. Workers on these systems may have been exposed during original installation and during every subsequent maintenance cycle requiring them to disturb existing insulation — which means cumulative exposure across an entire career.

Electricians

Electricians at facilities of this type may have encountered asbestos-containing materials while working in insulated equipment rooms, running conduit adjacent to pipe insulation, or handling asbestos-containing electrical insulation materials common in industrial facilities through the 1970s. Bystander exposure in areas with deteriorating thermal system insulation is documented in litigation records as a cause of disease — you do not have to be the one holding the pipe.

Millwrights and Industrial Mechanics

Maintenance on conveyors, crushers, kilns, and grinding mills required regular work with asbestos-containing gaskets, rope packing, and insulation. Every equipment disassembly or seal replacement allegedly disturbed asbestos-containing materials, releasing fiber into the immediate work environment. These workers often had no respiratory protection and no warning.

Trades with Significant Bystander Exposure Risk

Maintenance Workers and General Laborers

Bystander exposure — working in proximity to trades disturbing asbestos-containing materials — is firmly established in both scientific literature and decades of U.S. litigation as a sufficient cause of mesothelioma. Maintenance workers who cleaned, repaired, or simply worked near areas with asbestos-containing materials may have been exposed without ever directly handling those materials.

Cement Plant Operators and Floor Workers

Workers assigned to kilns, preheaters, and process equipment may have been exposed to fibers released from aged or damaged thermal system insulation during routine operations — not only during scheduled maintenance. NESHAP records document friable thermal system insulation integrated throughout facility structures (per MDNR NESHAP abatement records). Friable means it was releasing fiber.

Litigation Landscape

Workers at industrial cement and building materials manufacturing facilities like the Buzzi Unicem USA–Festus plant faced exposure to asbestos-containing products common throughout the mid-twentieth century. Litigation arising from such facilities has identified several manufacturers as frequent defendants, including Johns-Manville, Owens-Corning, Combustion Engineering, Crane Co., W.R. Grace, Garlock, Armstrong Industries, Babcock & Wilcox, and Eagle-Picher. These companies supplied insulation, gaskets, pipe wrapping, protective gear, and refractory materials widely used in cement production and associated industrial operations.

When workers develop asbestos-related diseases following exposure at such facilities, multiple compensation avenues may be available. Many of the manufacturers identified above established bankruptcy trust funds—including the Johns-Manville Settlement Trust, Owens-Corning Fibreboard Trust, Combustion Engineering Trust, Crane Co. Trust, and W.R. Grace Trust—specifically to compensate injured workers. Each trust operates under a documented claim procedure and holds substantial reserves for mesothelioma, lung cancer, and asbestosis claims.

Publicly filed litigation from industrial manufacturing facilities of this era demonstrates a consistent pattern: workers exposed to legacy asbestos products during production, maintenance, or equipment installation have successfully pursued both trust claims and direct litigation against responsible manufacturers. Claims typically identify multiple defendants based on documented asbestos-containing products used at the specific facility during the worker’s employment period.
