哥伦比亚特区巡回法院驳回了石化制造商,包括亨特斯曼石化公司提出的诉讼,对环保局2020年针对化学工厂致癌排放的规则提出质疑。 The District of Columbia Circuit Court rejected a lawsuit from petrochemical manufacturers, including Huntsman Petrochemical, challenging the EPA's 2020 rule targeting cancer-causing emissions from chemical plants. 环保局确定,用于抗冻和塑料的环氧乙烷对公众健康构成威胁。 The EPA determined that ethylene oxide, used in antifreeze and plastics, posed a threat to public health. 法院支持环保局将环氧乙烷评估作为一种致癌风险,支持环保局目前为控制排放和保护公共健康所作的努力。 The court upheld the EPA's assessment of ethylene oxide as a carcinogenic risk, supporting the agency's ongoing efforts to regulate emissions and protect public health.
