About Edwin Cooper Plant

The Edwin Cooper Plant is a petroleum additive and specialty chemical manufacturing facility in Sauget, Illinois, within the greater St. Louis metropolitan industrial corridor. The plant operated under Ethyl Corporation and affiliated entities, producing lubricant additives, fuel additives, and related petroleum chemistry products at commercial scale.

Sauget sits directly across the Mississippi River from St. Louis — at the heart of one of the most industrially dense stretches of the entire Mississippi River corridor. This corridor, running from St. Louis north through Granite City and Alton, Illinois, and south through the Missouri riverfront, was home to generations of pipefitters, insulators, boilermakers, and chemical plant workers who moved fluidly between job sites on both sides of the river. Workers who built or maintained the Edwin Cooper Plant may have also worked at Granite City Steel, Labadie Energy Center, Portage des Sioux Energy Center, Monsanto’s Sauget and St. Louis facilities, and other heavy industrial sites throughout the bi-state region.

Chemical manufacturing and petroleum processing facilities active during the mid-twentieth century ranked among the most intensive industrial environments for thermal insulation, high-pressure piping, and process equipment. The Edwin Cooper Plant, consistent with industry-wide practices of its time, reportedly relied on asbestos-containing materials (ACMs) throughout its construction phases and ongoing maintenance operations from at least the 1940s through the late 1970s and, in some areas, potentially into the 1980s.

Plant Infrastructure and High-Risk Areas

Facilities of this type typically included:

  • Distillation columns and reactors requiring high-temperature insulation
  • Extensive steam and process piping systems running throughout the plant
  • Boilers, heat exchangers, and fired heaters
  • Electrical switchgear rooms and control buildings
  • Maintenance shops and fabrication areas

Workers who spent careers at this facility — in construction, operations, or shutdown maintenance — may have encountered asbestos-containing materials throughout their daily work.

Documented Asbestos Evidence — Missouri

The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Missouri Department of Natural Resources (Missouri DNR) was notified under federal NESHAP rules, the work was logged, and the asbestos-containing material was confirmed and removed under regulated conditions. These are not allegations or estimates — they are paper records tying documented asbestos-containing material to this specific site.

No Missouri DNR NESHAP abatement notifications have been identified for this facility in current public records. Per the framing above, absence of state-agency documentation should not be read as absence of asbestos — only as absence of a formal, regulated abatement event meeting reporting thresholds. Workers who recall encountering pipe insulation, block insulation, gaskets, or other asbestos-era construction materials at this facility may still have viable claims regardless of whether a state record exists.

Who May Have Been Exposed at Edwin Cooper Plant

Asbestos exposure risk at the Edwin Cooper Plant was not limited to a single craft or occupation. Multiple trades allegedly worked in close proximity to asbestos-containing materials. In confined spaces, fibers disturbed by one trade were inhaled by every worker present.

The Mississippi River industrial corridor attracted tradespeople from across Missouri and Illinois. Workers who may have handled asbestos-containing materials at Edwin Cooper often carried the same exposures to other regional job sites — and workers based primarily at Missouri facilities such as Labadie Energy Center, Portage des Sioux Energy Center, or Granite City Steel may have logged significant hours at Edwin Cooper during turnarounds and construction shutdowns.

If you worked at any of these bi-state facilities and have since received a diagnosis, consulting with an asbestos attorney in Missouri is essential. Missouri’s 5-year personal-injury deadline under § 516.120 and the 3-year wrongful-death deadline under § 537.100 apply to Missouri-connected claims regardless of which side of the river the plant sits on, depending on where your legal claims are filed. Do not assume you have time to spare.

High-Exposure Crafts

Insulators (Heat and Frost Insulators)

  • Worked directly with asbestos-containing pipe covering, block insulation, and insulating cement daily
  • Cut, fit, and applied insulation to piping and equipment, generating substantial airborne fiber concentrations
  • During scheduled turnarounds and shutdowns, may have removed old, damaged insulation before applying new material — the highest-dust phase of the work
  • Heat and Frost Insulators and Allied Workers Local 1 (St. Louis) represented many of the insulators who worked at Edwin Cooper and throughout the bi-state industrial corridor; members of Local 1 are alleged to have worked at this plant across multiple construction and maintenance cycles

Pipefitters and Steamfitters

  • Worked on process piping networks throughout the plant, cutting pipe and assembling flanged joints
  • Allegedly handled asbestos-containing gaskets and packing materials and worked alongside lagged pipe
  • Frequently disturbed existing insulation to access pipe systems for repair or modification
  • United Association Local 562 (St. Louis) represented pipefitters and steamfitters throughout the bi-state area; UA Local 562 members are alleged to have performed construction and maintenance work at Edwin Cooper and at comparable facilities across the Missouri-Illinois corridor

Boilermakers

  • Serviced boilers, heat exchangers, and pressure vessels throughout the plant
  • Allegedly worked in direct contact with refractory lining materials, boiler rope, and insulating cements that may have contained asbestos fibers
  • Fired heaters and process furnaces carried similar alleged exposures
  • Boilermakers Local 27 (St. Louis) represented many of the craftspeople who performed boiler and pressure vessel work throughout the bi-state industrial corridor, including at chemical and petroleum facilities in Sauget

Moderate- to Bystander-Exposure Crafts

Electricians

  • May have been exposed through multiple pathways:
  • Cable tray systems and conduit runs often passed through fire-stopped penetrations reportedly packed with asbestos-containing materials
  • Drilling or cutting through fire-rated assemblies may have disturbed spray fireproofing
  • Some wire and cable insulation from this era is alleged to have contained asbestos fibers

Millwrights and Maintenance Mechanics

  • Serviced pumps and valves with asbestos-containing gaskets
  • Worked around insulated process equipment during routine maintenance

Process Operators

  • Did not handle asbestos-containing materials directly, but walked the units, monitored instrumentation, and responded to process upsets while maintenance activities released ambient airborne fibers throughout the facility
  • This bystander exposure carries full legal weight and supports valid claims

Construction and Renovation Tradespeople

  • Ironworkers, carpenters, laborers, and painters employed by outside contractors during construction and expansion phases may have encountered asbestos-containing materials in concentrated form during installation and finishing
  • Many of these workers were dispatched through St. Louis-area union halls and traveled regularly between Missouri and Illinois job sites throughout the same construction season

Missouri — Filing Deadline & Next Steps

Missouri law gives mesothelioma and asbestos-disease claimants 5 years from the date of medical diagnosis to file a personal-injury lawsuit (Mo. Rev. Stat. § 516.120). For wrongful-death claims after an asbestos-related death, the filing window is 3 years from the date of death (Mo. Rev. Stat. § 537.100). The two deadlines run on separate tracks — preserving one does not extend the other.

The personal-injury clock runs from diagnosis, not from exposure. Mesothelioma latency is typically 20 to 50 years, so workers exposed in the 1950s–1980s are being diagnosed today.

Practical first steps

  1. Document what you remember. Pay stubs, W-2s, union cards, photographs, coworker names, and dates of employment. The WorkChain widget on this page can save a copy you can email yourself.
  2. Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
  3. Identify household members. Spouses who laundered work clothing and children of plant workers are eligible for secondary-exposure claims when diagnosed with an asbestos-related disease.
  4. Speak with an asbestos attorney with Missouri experience. The first conversation is free and confidential. Asbestos trust-fund claims and civil claims run on different tracks — both can be pursued in parallel.

Asbestos-Related Diseases — Missouri

Asbestos fiber exposure can cause several specific diseases that typically appear decades after the original exposure. The latency period — the gap between exposure and diagnosis — usually runs 20 to 50 years. That's why workers exposed in the 1960s, 1970s, and 1980s are receiving diagnoses today.

Mesothelioma

A rare, aggressive cancer that affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal), or heart (pericardial). Mesothelioma is almost exclusively caused by asbestos exposure, which is why a mesothelioma diagnosis often points directly to historical workplace exposure. Average latency from first exposure to diagnosis is 30-50 years.

Asbestosis

A chronic, non-cancerous scarring of lung tissue caused by inhaled asbestos fibers. Asbestosis causes progressive shortness of breath, persistent cough, and reduced lung function. It does not improve with treatment, and it is a recognized basis for a claim under most trust schedules and civil claims.

Lung Cancer

Asbestos exposure significantly increases the risk of lung cancer, particularly when combined with a history of smoking. Asbestos-related lung cancer is compensable under the same trust schedules and civil claim avenues as mesothelioma.

Other Recognized Diseases

Pleural plaques, pleural thickening, laryngeal cancer, ovarian cancer, and certain gastrointestinal cancers are also recognized as asbestos-related under various trust schedules and case-law authorities, though eligibility and proof requirements vary by claim type.

If you have any of these diagnoses and you worked at this facility, lived with someone who did, or were exposed in any documented capacity, you may have a claim worth pursuing. Speak with an attorney before assuming you don't qualify.
