The U.S. Environmental Protection Agency is proposing to amend existing regulations to implement certain provisions of the American Innovation and Manufacturing Act, as enacted on December 27, 2020. This rulemaking proposes to establish the methodology for allocating hydrofluorocarbon production and consumption allowances for the calendar years of 2024 through 2028. EPA is also proposing to amend the consumption baseline to reflect updated data and to make other adjustments based on lessons learned from the implementation of the hydrofluorocarbon phasedown program thus far, including proposing to: codify the existing approach of how allowances must be expended for import of regulated substances; revise recordkeeping and reporting requirements; and implement other modifications to the existing regulations.
