KANSAS CITY, Kan. (LN) — U.S. District Judge Kathryn H. Vratil on Friday denied in part a motion to dismiss a class action lawsuit alleging that Harcros Chemicals Inc. exposed the surrounding community to carcinogenic emissions, allowing key negligence and strict liability claims to proceed against the chemical manufacturer.
The plaintiffs, representing a class of individuals who lived, worked, or attended school within a 2.5-mile radius of the facility at 5200 Speaker Rd in Kansas City, Kansas, allege that the plant’s emissions of ethylene oxide and other toxins caused cancers and miscarriages.
Harcros sought to dismiss the claims of three named plaintiffs—Rocky Garner, Kenique Smith, and Estelle White—arguing that the Kansas statute of repose barred their suits because their exposures occurred more than 10 years ago.
Vratil sustained the motion as to those three plaintiffs and the estate of Cecil B. McBee, whose claims were barred of repose.
The judge rejected the plaintiffs’ attempt to invoke the Kansas Products Liability Act’s latent disease exception, ruling that the exception applies only to defective product claims, not to torts arising from toxic emissions.
“Plaintiffs’ harm does not arise from Harcros products themselves, but rather the emissions which result from the manufacture, storage and transport processes related thereto,” Vratil wrote.
The court also dismissed the plaintiffs’ negligent construction claim, finding it waived and barred of repose, though it allowed claims for negligent repair and maintenance to stand.
However, Vratil overruled the motion to dismiss the remaining claims, including strict liability for abnormally dangerous activities, negligence, wrongful death, and failure to warn.
The judge concluded that the plaintiffs’ complaint provided sufficient factual matter to state a plausible claim, particularly regarding the high degree of risk posed by ethylene oxide emissions.
“Expert-level causation analysis of exposure levels is not necessary at this stage,” Vratil wrote, noting that summa-canister testing in June 2025 detected ethylene oxide concentrations exceeding 2,000 parts per billion near the facility.
The plaintiffs allege that the facility, which has operated since 1961, emitted dangerous quantities of neurotoxins and human carcinogens, contaminating the air and soil in surrounding neighborhoods.
The complaint cites a 2016 study finding that the average age at death of the facility was about 20 years lower than in nearby Wyandotte County.
Vratil held that the plaintiffs adequately alleged that Harcros owed a duty to exercise reasonable care for the health and safety of individuals living, working, or attending school near the facility.
The court also held that the plaintiffs sufficiently pleaded causation, noting that their allegations that high levels of ethylene oxide leaked and dispersed into the surrounding area were legally sufficient at the motion to dismiss stage.
The wrongful death claim brought on behalf of Weston T. Lawson, who died before age 4 from leukemia, also survived dismissal.
Vratil held that the complaint’s allegations that Lawson was exposed to toxic emissions in utero and throughout his short life were sufficient under notice pleading standards.
The failure to warn claim also proceeded, with the judge holding that the plaintiffs plausibly alleged that Harcros knew of the hazards but made no effort to warn the surrounding communities.
The court allowed the plaintiffs to pursue punitive damages, ruling that while punitive damages are a remedy rather than a cause of action, the plaintiffs sufficiently alleged facts to support such relief.
The case continues in U.S. District Court for the District of Kansas.
