EPA: Phasedown of Hydrofluorocarbons: Allowance Allocation Methodology for 2024 and Later Years

July 20, 2023

SUMMARY: The U.S. Environmental Protection Agency (EPA) is amending existing regulations to implement certain provisions of the American Innovation and Manufacturing Act. This rule establishes the methodology for allocating hydrofluorocarbon production and consumption allowances for the calendar years of 2024 through 2028. EPA is also amending the consumption baseline to reflect updated data and to make other adjustments based on lessons learned from implementation of the hydrofluorocarbon phasedown program thus far, including 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.

DATES: This final rule is effective on September 18, 2023, except for amendatory instructions 3 and 13, which are effective October 1, 2024, published in the Federal Register July 20, 2023, page 46836.

§84.5 Prohibitions relating to regulated substances.

* * * *

(b) Import. This paragraph applies starting January 1, 2022.

(1) No person may import bulk regulated substances, either as a single component or a multicomponent substance, except:

(i) If the importer of record possesses at the time they are required to submit reports to EPA pursuant to §84.31(c)(7), and expends at the time of ship berthing for vessel arrivals, border crossing for land arrivals such as trucks, rails, and autos, and first point of terminus in U.S. jurisdiction for arrivals via air, consumption or application-specific allowances in a quantity equal to the exchange-value weighted equivalent of the regulated substances imported, whether present as a single component or a multicomponent blend. The required amount of allowances must be calculated to the tenth, but a minimum expenditure of 0.1 allowances is required for any import of regulated substances;

(ii) After receipt of a non-objection notice for substances for use in a process resulting in their transformation or their destruction in accordance with §84.25(a);

(iii) After receipt of a non-objection notice for used regulated substances imported for destruction in accordance with §84.25(b);

(iv) As a transhipment in accordance with §84.31(c)(3) if all transhipped regulated substance is exported from the United States within six months of its import; or

(v) All imports pursuant to paragraph (b)(1)(i) or (ii) of this section must be physically accompanied by a certificate of analysis, if the certificate of analysis has not been electronically submitted pursuant to §84.31(c)(7)(xvi).

(2) No person may attempt to land bulk regulated substances on, bring regulated substances into, or introduce regulated substances into, any place subject to the jurisdiction of the United States without meeting one of the categories set forth in §84.5(b)(1).

(3) Each person meeting the definition of importer for a particular regulated substance import transaction is jointly and severally liable for a violation of paragraph (b)(1) of this section, unless they can demonstrate that another party who meets the definition of an importer met one of the exceptions set forth in paragraph (b)(1).

(4) Imports authorized under paragraph (b)(1)(ii) of this section may not be in containers designed to hold 100 pounds or less of a regulated substance.

(5) A person issued a non-objection notice for the import of an individual shipment of regulated substances under paragraph (b)(1)(ii) or (iii) of this section may not transfer or confer the right to import.

(6) No person may introduce into U.S. commerce any regulated substance claimed as a transhipment.

(7) Every kilogram of bulk regulated substances imported contrary to this paragraph (b) constitutes a separate violation of this subpart. Import of less than one kilogram of bulk regulated substance contrary to this paragraph (b) constitutes a separate violation of this subpart.

* * * *

(d) Calendar-year allowances. All production, consumption, and application-specific allowances may only be expended for production or import occurring in the calendar year for which the allowances are allocated ( i.e., January 1 through December 31). No person may expend, transfer, or confer a production, consumption, or application-specific allowance after December 31 of the year for which it was issued. Entities may transfer or confer their production, consumption, or application-specific allowances before January 1 of the calendar year for which the allowances were allocated.

* * * * *

(i) Labeling. (1) As of January 1, 2022, no person may sell or distribute, offer for sale or distribution, or import containers containing a regulated substance that lacks a label or other permanent markings stating the common name(s), chemical name(s), or ASHRAE designation of the regulated substance(s) or blend contained within, and the percentages of the regulated substances if a blend. The label or other permanent markings must be:

(i) Durable and printed or otherwise labeled on, or affixed to, the external surface of the bulk regulated substance container;

(ii) Readily visible and legible;

(iii) Able to withstand open weather exposure without a substantial reduction in visibility or legibility;

(iv) Displayed on a background of contrasting color; and

(v) If a container of a regulated substance is contained within a box or other overpack, the exterior packaging must contain legible and visible information of what regulated substance is contained within.

(2) No person other than the importer of record may repackage or relabel regulated substances that were initially unlabeled or mislabeled. In order to repackage the regulated substances, the importer of record must either:

(i) Expend consumption allowances equal to the amount of allowances that would be required if each cylinder were full of HFC–23; or

(ii) Verify the contents with independent laboratory testing results and affix a correct label on the container that matches the lab-verified test results before the date of importation (consistent with the definition at 19 CFR 101.1) of the container.

(3)(i) No person producing, importing, exporting, reclaiming, recycling for fire suppression, or repackaging regulated substances, whether as a single or multicomponent substance, may sell or distribute, or offer for sale or distribution, those regulated substances without first conducting laboratory testing of a representative sample of the regulated substances that they are producing, importing, exporting, reclaiming, recycling for fire suppression, or repackaging to verify that the composition of the regulated substance(s) matches the container labeling using the sampling and testing methodology prescribed in appendix A to 40 CFR part 82, subpart F for regulated substances offered for sale and distribution as refrigerants and using the following sampling and testing method for regulated substances offered for non-refrigerant uses:

§84.9 Allocation of calendar-year production allowances.

(a) The relevant agency official will issue, through a separate notification, calendar year 2022 and 2023 production allowances to entities that produced a regulated substance in 2020. The number of production allowances allocated to each eligible entity for 2022-2023 is calculated as follows:

§84.11 Allocation of calendar-year consumption allowances.

(a) The relevant agency official will issue, through a separate notification, calendar years 2022 and 2023 consumption allowances to entities that imported or produced a bulk regulated substance in 2020, unless an individual accommodation is permitted by a relevant Agency official. If multiple entities that imported are related through shared corporate or common ownership or control, the relevant agency official will calculate and issue allowances to a single corporate or common owner. The number of consumption allowances allocated to each eligible entity for 2022-2023 is calculated as follows:

§84.17 Availability of additional consumption allowances.
