EPA Sends Phasedown of Hydrofluorocarbons NPRM to OMB

Yesterday the OMB’s Office of Information and Regulatory Affairs (OIRA) announced that it had received an notice of proposed rulemaking (NPRM) from the EPA on “Phasedown of Hydrofluorocarbons: Reconsideration of Technology Transitions Final Rule Under the American Innovation and Manufacturing Act of 2020”.

According to the Spring 2024 Unified Agenda entry for this rulemaking:

“The U.S. Environmental Protection Agency received petitions to reconsider certain provisions of the Technology Transitions final rule established under subsection (i) of the American Innovation and Manufacturing (AIM) Act. This proposal would reconsider topics raised by those petitions including adjustments to restrictions for refrigeration equipment used in semiconductor manufacturing and intermodal refrigerated transport and related to the continued manufacture and sale of condensing units in the residential and light commercial air conditioning and heat pump subsector. The proposed rule would also amend and clarify other provisions of the 2023 Technology Transitions rule in addition to those covered by the petitions.”

This should be interesting, a Trump EPA’s take on a Biden EPA’s response to petitions for relief from an early key piece of Biden’s legislative agenda.
