Liability Considerations in Vernon
Vernon's Industrial Zone and Adjacent Residential Communities
Vernon is one of the smallest cities in California by population — an industrial enclave of just 222 residents surrounded by densely populated working-class communities including Maywood (population 27,000), Bell (population 36,000), and Commerce (population 13,000). Sterigenics's Vernon facility sits in this industrial zone, but EtO emissions do not respect city boundaries. Wind patterns carry the gas into the residential neighborhoods of these adjacent communities, where predominantly Latino families have lived for decades without knowledge of the exposure.
This geographic dynamic creates a powerful environmental justice narrative. Vernon's deliberate identity as an industrial city with virtually no residents means there is no local constituency to complain about emissions. The burden of the pollution falls entirely on the adjacent communities of color whose residents had no say in Vernon's land use decisions. Plaintiffs' attorneys are leveraging California's strong environmental justice framework and the documented disparate impact on these communities.
Proposition 65 and LA County Environmental Justice Claims
California's Proposition 65 requires businesses to provide clear and reasonable warnings before knowingly exposing individuals to chemicals that cause cancer or reproductive harm. Ethylene oxide is listed under Prop 65 as a known carcinogen. A Prop 65 notice has been issued for the Vernon Sterigenics facility, opening a separate legal theory beyond traditional negligence. Under Prop 65, the burden shifts to the defendant to prove that its exposures fall below the "no significant risk level" — a powerful advantage for plaintiffs.
The combination of Prop 65, California's strong discovery rule (which tolls the statute of limitations until the plaintiff discovers or should have discovered the injury), and California's recognition of enhanced damages for environmental justice violations gives Maywood, Bell, and Commerce residents multiple overlapping legal theories. Los Angeles Superior Court juries have a history of substantial verdicts in environmental contamination cases, making this a favorable venue for EtO litigation.
