The Environmental Protection Agency (EPA) is providing notice that the Agency allocated hydrofluorocarbon (HFC) set-aside allowances to general pool production and consumption allowance holders. For the calendar year 2026 allocation of HFC allowances, the EPA withheld a limited number of allowances from all general pool allowance holders.
