Phasedown of Hydrofluorocarbons: Restrictions on the Use of Certain Hydrofluorocarbons Under Subsection (i) the American Innovation and Manufacturing Act of 2020

Riepilogo

The U.S. Environmental Protection Agency is proposing to issue regulations to implement certain provisions of the American Innovation and Manufacturing Act, as enacted on December 27, 2020. This rulemaking proposes to: restrict the use of hydrofluorocarbons in specific sectors or subsectors in which they are used; establish a process for submitting technology transitions petitions; establish recordkeeping and reporting requirements; and address certain other elements related to the effective implementation of the American Innovation and Manufacturing Act. The proposed restrictions on the use of hydrofluorocarbons would, in part, address petitions granted on October 7, 2021, and September 19, 2022. The U.S. Environmental Protection Agency is also seeking advance information on certain topics that may be helpful to developing a future proposed rule including on restrictions on the use of hydrofluorocarbons for certain other sectors and subsectors and on a third-party auditing program to verify substances used in products.
