Curb Your Pollution: EPA Issues Final Rule to Reduce Toxic Air Pollution

EPA Issues Final Rule to Reduce Toxic Air Pollution from the Synthetic Organic Chemical Manufacturing Industry and the Polymers and Resins Industries

On April 9, 2024, the U.S. Environmental Protection Agency (EPA) announced its final rule that is touted to provide critical health protections to hundreds of thousands of people living near chemical plants. The final rule, signed March 28, 2024, will reduce emissions of hazardous air pollutants, including the toxic chemicals chloroprene and ethylene oxide (EtO). The rule implements sections 111 and 112 of the Clean Air Act.

When fully implemented, the final rule will reduce more than 6,200 tons a year of over 100 air toxics – including EtO and chloroprene – from covered equipment and processes at plants in Texas and Louisiana, along with plants in other parts of the country including Delaware, New Jersey, and the Ohio River Valley.

As part of the final rule, the EPA is also issuing new emissions limits for dioxins and furans. This will reduce more than 23,000 tons of smog-forming volatile organic compounds (VOCs) each year.

EPA’s final rule will also require plants to conduct fenceline monitoring if any of the equipment or processes covered by the rule use, produce, store, or emit EtO, chloroprene, benzene, 1,3- butadiene, ethylene dichloride or vinyl chloride. Fenceline monitoring is used to measure levels of pollution in the air around the perimeter of a facility. The fenceline monitoring provisions of the rule require owners and operators to ensure that levels of these six pollutants remain below a specified “action level.” Fenceline monitoring provides owners and operators the flexibility to determine what measures to take to remain below the action level, while ensuring that they are effectively controlling toxic air pollution.

The final rule will significantly reduce emissions of air toxins, especially those that are potentially harmful for surrounding communities. According to the EPA, these emission reductions will yield significant reductions in lifetime cancer risk attributable to these air pollutants, in addition to other health benefits.
