ELR Citation: 54 ELR 20117
No(s). 23-1045 (D.C. Cir. Aug 13, 2024)

The D.C. Circuit denied a chemical manufacturer's and two trade groups' petitions to review EPA's 2020 rule regulating emissions from miscellaneous organic chemical manufacturing facilities. The petitioners challenged EPA's assessment of cancer risk from exposure to ethylene oxide emissions. The court found petitioners failed to show EPA's modeling of the lymphoid cancer risk of ethylene oxide was arbitrary and capricious, and found no merit in their arguments that EPA committed procedural errors in promulgating the rule and issuing a reconsideration decision. It denied the petitions for review.
