EPA issued a final rule that will significantly reduce toxic air pollution from chemical plants, including ethylene oxide and chloroprene. EPA's action will advance the President's commitment to environmental justice by slashing more than 6,200 tons of toxic air pollution each year, dramatically reducing the number of people with elevated cancer risk due to toxic air pollution in communities surrounding plants covered by the rule. Once implemented, the rule will reduce both EtO and chloroprene emissions from covered processes and equipment by nearly 80%. A requirement for these facilities to conduct fence line monitoring for key toxic chemicals is included, and EPA will make the data publicly available to better inform and safeguard nearby communities.
