Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I & II Polymers and Resins Industry".

HJRES 161 is a congressional disapproval resolution targeting an EPA rule that set emissions standards for chemical manufacturing. It directly affects synthetic organic chemical manufacturers and polymers/resins producers by seeking to nullify the EPA's May 2024 rule (89 Fed. Reg. 42932), which established new source performance standards and hazardous air pollutant limits for these industries. The resolution uses Chapter 8 of Title 5, U.S. Code, to formally block the EPA rule from taking effect. If passed, the rule would lose all legal force, preventing the EPA from enforcing those specific emissions requirements.
