EPA issues final rule for HFC phasedown
On September 23, 2021, EPA Administrator Michael S. Regan signed a final rule to cap and phase down the production and consumption of hydrofluorocarbons (HFCs) in the United States. This final rule will phase down the U.S. production and consumption of 15 listed HFCs (40 CFR 84 appendix A) over the next 15 years. The new regulation, which will be found at 40 Code of Federal Regulation (CFR) Part 84, becomes mostly effective 30 days after it appears in the Federal Register. The exception to that 30-day applicability takes effect immediately and applies only to EPA’s task of determining allocation allowances. The American Innovation and Manufacturing (AIM) Act established an October 1, 2021, deadline for these allocations and therefore require EPA to continue working on this as the rule is finalized. The final rule establishes the HFC baseline levels from which reductions will be made; establishes a methodology for allocating the next two years of HFC allowances; outlines recordkeeping, reporting, and auditing requirements; and creates an enforcement system for the program.
The total annual allocations for 2022 and 2023 are 344.3 million metric tons of exchange value equivalent (MMTEVe) of production allowances and 273.5 MMTEVe of consumption allowances. EPA intends to issue allowances for 2022 by October 1, 2021. Allocations will be made based on the three highest years (not necessarily consecutive) of production or consumption between 2011 and 2019. EPA is issuing allowances to active HFC producers and importers operating in 2020 with some exceptions being made for historical importers that were not active in 2020. The current allocation methodology is being implemented for only 2022 and 2023 with a plan to use future rulemaking to determine allocations for calendar years 2024 and beyond.
The final rule addressed many public comments with application-specific allowances that will be available for calendar years 2022 through 2025. This exception allows regulated substances to continue being used in cases where alternatives are not available, including propellants in metered dose inhalers, use in defense sprays (such as bear spray), onboard aerospace fire suppression, as well as others (see 40 CFR 84.13 for the full list).
In the last part of this rulemaking, EPA has included a unique approach to deter, identify, and penalize illegal activity. This includes administrative consequences for allowance holders, requiring use of refillable cylinders, increased oversight of imports, third-party auditing, and comprehensive tracking of containers of HFCs as they are imported, sold, and distributed.
