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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: 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 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.

DATES: Comments on this notice of proposed rulemaking must be received 
on or before December 19, 2022. Under the Paperwork Reduction Act 
(PRA), comments on the information collection provisions are best 
ensured of consideration if the Office of Management and Budget (OMB) 
receives a copy of your comments on or before December 5, 2022. Any 
party requesting a public hearing must notify the contact listed below 
under FOR FURTHER INFORMATION CONTACT by 5 p.m. Eastern Daylight Time 
on November 8, 2022. If a virtual public hearing is held, it will take

 Codes marked with an asterisk may apply to sectors that receive

    This table is not intended to be exhaustive, but rather provide a 
guide for readers regarding entities likely to be affected by this 
action. Other types of entities not listed in this section could also 
be affected. If you have any questions regarding the applicability of 
this action to a particular entity, consult the person listed under FOR 
FURTHER INFORMATION CONTACT.

B. What is the AIM Act, and what authority does it provide to EPA as it 
relates to this proposed action?

    On December 27, 2020, the AIM Act was enacted as section 103 in 
Division S, Innovation for the Environment, of the Consolidated 
Appropriations Act, 2021 (42 U.S.C. 7675). The AIM Act authorizes EPA 
to address HFCs in three main ways: phasing down HFC production and 
consumption through an allowance allocation program; facilitating 
sector-based transitions to next-generation technologies; and 
promulgating certain regulations for purposes of maximizing reclamation 
and minimizing releases of HFCs and their substitutes from equipment. 
This rulemaking focuses on the first area--the phasedown of the 
production and consumption of HFCs.
    Subsection (e) of the AIM Act gives EPA authority to phase down the 
production and consumption of listed HFCs through an allowance 
allocation and trading program. Subsection (c)(1) of the AIM Act lists 
18 saturated HFCs, and by reference any of their isomers not so listed, 
that are covered by the statute's provisions, referred to as 
``regulated substances'' under the Act. Congress also assigned an 
``exchange value'' 1 2 to each regulated substance (along 
with other chemicals that are used to calculate the baseline). EPA has 
codified the list of the 18 regulated substances and their exchange 
values in appendix A to 40 CFR part 84.
---------------------------------------------------------------------------

    \1\ EPA has determined that the exchange values included in 
subsection (c) of the AIM Act are identical to the global warming 
potentials (GWPs) included in the Intergovernmental Panel on Climate 
Change (IPCC) (2007). EPA uses the terms ``global warming 
potential'' and ``exchange value'' interchangeably in this proposal.

and H.L. Miller (eds.)]. Cambridge University Press, Cambridge, 
United Kingdom and New York, NY, USA https://www.ipcc.ch/report/ar4/wg1.
---------------------------------------------------------------------------

    The AIM Act requires EPA to phase down the consumption and 
production of the statutorily listed HFCs on an exchange value-weighted 
basis according to the schedule in subsection (e)(2)(C) of the AIM Act. 
The AIM Act requires that the EPA Administrator ensures the annual 
quantity of all regulated substances produced or consumed \3\ in the 
United States does not exceed the applicable percentage listed for the 
production or consumption baseline. EPA has codified the phasedown 
schedule at 40 CFR 84.7.
---------------------------------------------------------------------------

    \3\ In the context of allocating and expending allowances, EPA 
interprets the word ``consume'' as the verb form of the defined term 
``consumption.'' For example, subsection (e)(2)(A), states the 
phasedown consumption prohibition as ``no person shall . . . consume 
a quantity of a regulated substance without a corresponding quantity 
of consumption allowances.'' While a common usage of the word 
``consume'' means ``use,'' EPA does not believe that Congress 
intended for everyone who charges an appliance or fills an aerosol 
can with an HFC to expend allowances.
---------------------------------------------------------------------------

    To implement the directive that the production and consumption of 
regulated substances in the United States does not exceed the statutory 
targets, the AIM Act in subsection (e)(3) requires EPA to issue 
regulations establishing an allowance allocation and trading program to 
phase down the production and consumption of the listed HFCs. These 
allowances are limited authorizations for the production or consumption 
of regulated substances. Subsection (e)(2) of the Act has a general 
prohibition that no person \4\ shall produce or consume a quantity of 
regulated substances in the United States without a corresponding 
quantity of allowances.
---------------------------------------------------------------------------

    \4\ Under the Act's term, this general prohibition applies to 
any ``person.'' Because EPA anticipates that the parties that 
produce or consume HFCs--and that would thus be subject to the Act's 
production and consumption controls--are companies or other 
entities, we frequently use those terms to refer to regulated 
parties in this proposal. Using this shorthand, however, does not 
alter the applicability of the Act's or regulation's requirements 
and prohibitions. Similarly, in certain instances EPA may use these 
terms interchangeably in this rule preamble, but such differences in 
terminology should not be viewed to carry a material distinction in 
how EPA interprets or is planning to apply the requirements 
discussed herein.
---------------------------------------------------------------------------

    EPA published a final rule on October 5, 2021 (86 FR 55116; 
hereinafter called the Framework Rule), that, among other things: 
established the HFC production and consumption baselines; determined an 
initial approach to allocating production and consumption allowances 
for 2022 and 2023, identifying both the entities receiving allowances 
and how to determine what quantities of allowances they would receive; 
established a process for issuing ``application-specific'' allowances 
to entities in six specific applications listed in subsection 
(e)(4)(B)(iv) of the AIM Act; created a set-aside pool of allowances 
for new entrants and entities for which the Agency did not have 
verifiable data prior to the finalization of the rule; established 
provisions for the transfer of allowances; established recordkeeping 
and reporting requirements; and established a suite of

[[Page 66375]]

compliance and enforcement-related provisions. Unless otherwise stated 
in the proposal sections included in this notice, EPA's proposed 
requirements and revisions are based on the same interpretations of the 
AIM Act, and the Clean Air Act as applicable under subsection (k) of 
the AIM Act, as discussed in the Framework Rule. EPA also has inherent 
authority to prevent and identify noncompliance, to ensure the Agency 
can meet the statutory directive in subsection (e)(2)(B), and to create 
a level playing field for the regulated community.

C. What are HFCs?

    HFCs are anthropogenic \5\ fluorinated chemicals that have no known 
natural sources. HFCs are used in a variety of applications such as 
refrigeration and air conditioning, foam blowing agents, solvents, 
aerosols, and fire suppression. HFCs are potent greenhouse gases (GHGs) 
with 100-year GWPs (a measure of the relative climatic impact of a GHG) 
that can be hundreds to thousands of times that of carbon dioxide 
(CO2).
---------------------------------------------------------------------------

    \5\ While the overwhelming majority of HFC production is 
intentional, EPA is aware that HFC-23 can be a byproduct associated 
with the production of other chemicals, including but not limited to 
hydrochlorofluorocarbon (HCFC)-22.
---------------------------------------------------------------------------

    HFC use and emissions,\6\ have been growing worldwide due to the 
global phaseout of ozone-depleting substances (ODS) under the Montreal 
Protocol on Substances that Deplete the Ozone Layer (Montreal 
Protocol), and the increasing use of refrigeration and air-conditioning 
equipment globally. HFC emissions had previously been projected to 
increase substantially over the next several decades. In 2016, in 
Kigali, Rwanda, countries agreed to adopt an amendment to the Montreal 
Protocol, known as the Kigali Amendment, which provides for a global 
phasedown of the production and consumption of HFCs. Global adherence 
to the Kigali Amendment would substantially reduce future emissions, 
leading to a peaking of HFC emissions before 2040.7 8

    \7\ Ibid.
    \8\ A recent study estimated that global compliance with the 
Kigali Amendment is expected to lower 2050 annual emissions by 3.0-
4.4 Million Metric Tons of Carbon Dioxide Equivalent 
(MMTCO2e). Guus J.M. Velders et al. Projections of

---------------------------------------------------------------------------

    Atmospheric observations of most currently measured HFCs confirm 
their abundances are increasing at accelerating rates. Total emissions 
of HFCs increased by 23 percent from 2012 to 2016 and the four most 
abundant HFCs in the atmosphere, in GWP-weighted terms, are HFC-134a, 
HFC-125, HFC-23, and HFC-143a.\9\
---------------------------------------------------------------------------

    \9\ WMO, 2018.
---------------------------------------------------------------------------

    In 2016, HFCs, excluding HFC-23, accounted for a radiative forcing 
\10\ of 0.025 W/m\2\: This is a 36 percent increase in total HFC 
forcing relative to 2012. Under status quo conditions, this radiative 
forcing was projected to increase by an order of magnitude to 0.25 W/
m\2\ by 2050.\11\ If the Kigali Amendment were to be fully implemented, 
it would be expected to reduce the future radiative forcing due to HFCs 
(excluding HFC-23) to 0.13 W/m\2\ in 2050 which is a reduction of about 
50 percent compared with the radiative forcing projected in the 
business-as-usual scenario of uncontrolled HFCs.\12\

    There are hundreds of possible HFC compounds. The 18 HFCs listed as 
regulated substances by the AIM Act are some of the most commonly used 
HFCs and have high impacts as measured by the quantity of each 
substance emitted multiplied by their respective GWPs. These 18 HFCs 
are all saturated, meaning they have only single bonds between their 
atoms and therefore have longer atmospheric lifetimes.
    In the United States, HFCs are primarily used in refrigeration and 
air-conditioning equipment in homes, commercial buildings, and 
industrial operations (approximately 75 percent of total HFC use in 
2018) and in air conditioning in vehicles and refrigerated transport 
(approximately 8 percent). Smaller amounts are used in foam products 
(approximately 11 percent), aerosols (approximately 4 percent), fire

(approximately 1 percent).\13\

III. How is EPA proposing to determine allowance allocations starting 
in 2024?

    This section provides an overview of EPA's proposal to establish a 
methodology for issuing calendar year production and consumption 
allowances starting in calendar year 2024. In the Framework Rule, EPA 
codified an initial approach to allocating production and consumption 
allowances for calendar years 2022 and 2023, and did not establish any 
allocation methodology for further years. This rulemaking proposes an 
approach to calculating production and consumption allowance 
allocations for future calendar years, beginning with calendar year 
2024 allowances. EPA is proposing that this methodology would apply for 
calculating production and consumption allowances for calendar years 
2024 through 2028.
    The Framework Rule established that application-specific allowances 
would be available to identified entities for calendar years 2022, 
2023, 2024, and 2025. EPA is not proposing to change the methodology 
for issuing application-specific allowances through this rulemaking. 
The existing application-specific allowance allocation methodology 
codified at 40 CFR 84.13 will continue to apply as finalized in the 
Framework Rule.
    Subsection (e)(3) of the AIM Act requires EPA to implement the 
statutorily established phasedown of the production and consumption of 
regulated substances through an allowance allocation program. Congress 
established a cap on the number of allowances available each year (by 
defining how to calculate the baseline and requiring a set percentage 
reduction in specific years from that baseline) and requires EPA to 
establish ``an allowance allocation and trading program.''
    In the Framework Rule, EPA made clear that the Agency intended to 
revisit how to allocate production and consumption allowances for 2024 
and beyond. EPA presented and took advance comment on ideas on 
potential criteria and a framework for issuing allowances for 2024 and 
later years. EPA stated that comments received on the elements noted 
for advance comment would be taken under advisement by the Agency and 
incorporated, as appropriate, in future and separate rulemakings with 
an opportunity for public comment prior to finalization of any 
provisions. Accordingly, EPA has considered the advance comments 
provided on potential methodology for allocation methodologies starting 
with calendar year 2024 allowances in development of this proposal. 
Those comments can be found at Docket ID No. EPA-HQ-OAR-2021-0044. EPA 
is not including those comments in the docket for this rule, does not 
consider those advance comments to be part of this rulemaking record, 
and does not anticipate providing any further response to them.

A. For which years is EPA proposing to establish the allocation 
methodology?

    EPA is proposing to establish a methodology for allocating 
production and consumption allowances for calendar year 2024 through 
2028. During these five years, the annual production and consumption 
caps established in the AIM Act are 60 percent of the baseline.\15\ EPA 
is proposing to establish a consistent methodology for the duration of 
this next phasedown step.
---------------------------------------------------------------------------

    \15\ In 2029, the production and consumption caps decline to 30 
percent of baseline.
---------------------------------------------------------------------------

    In the phaseout of HCFCs, which EPA is implementing under Title VI 
of the Clean Air Act, EPA has similarly used an approach of 
periodically revisiting its allocation methodology and has found that a 
periodic revisiting of the allowance allocation methodology allowed the 
Agency to respond to changing market conditions or challenges in 
program implementation. Examples of changes in market conditions that 
the Agency could potentially consider in revisiting its methodology in 
the HFC phasedown include, among other things, companies entering or 
exiting the market, corporate mergers and acquisitions, significant 
quantities of allowances unexpended at the end of the year, and/or 
supply shortages for specific HFCs. EPA is proposing to implement the 
current methodology through allocation of calendar year 2028 allowances 
to align the next periodic revisiting of the methodology with the next 
phasedown step, which occurs in 2029. This allows EPA to consider 
lessons learned from implementation, prior year use of allowances, and 
any concerns surrounding distribution of allowances prior to the next 
reduction in the production and consumption caps. For example, EPA 
might want to adjust the allocation methodology if certain allowance 
allocations are not being expended, leading to supply constraints, or 
if there are concerns of market disruptions tied to the next phasedown 
step that EPA could alleviate through a change in allocation 
methodology. Establishing a methodology for these five years, as 
opposed to a shorter period of time, is intended to provide allowance 
holders a predictable understanding of a likely range of allocation 
levels for these five years so they can make longer term decisions and 
plans about how to deploy their allowances (e.g., whether to transfer 
or produce or import directly).
    While the Agency's primary proposal is to establish an allowance 
methodology through 2028 and reassess the methodology for allocation of 
calendar year 2029 production and consumption allowances, EPA is also 
considering whether it may be less disruptive to the market to reassess 
and potentially change methodologies in a year prior to or after a 
phasedown step (e.g., alter the methodology for allocation of calendar 
year 2028 or 2030 allowances, instead of aligning with the next 
phasedown step in 2029). EPA is also interested in commenters' input on 
whether it is appropriate to establish the methodology through a 
different phasedown step, such as through the allocation of calendar 
year 2036 allowances when the production and consumption caps reach 15 
percent of baseline.

B. What is EPA's proposed framework for determining how many allowances 
each entity receives?

    This section discusses how EPA proposes to determine the quantity 
of production and consumption allowances each entity would receive. As 
in the Framework Rule, EPA seeks to provide as seamless a transition as 
possible as HFCs are phased down, ensure that the methodology is in 
place before October 1, 2023,\16\ and develop a methodology that 
utilizes robust data. EPA is proposing to use a similar methodology to 
calculate allocation quantities as the initial framework used for 
allocating calendar year 2022 and 2023 production and consumption 
allowances, with adjustments to accommodate new market entrants \17\ 
that received allowances from EPA on March 31, 2022, pursuant to 40 CFR 
84.15(e)(3). EPA is not proposing to establish another pool of set-
aside allowances. Nor is EPA proposing any change to the methodology 
outlined in

[[Page 66377]]

40 CFR 84.13 for determining application-specific allowance allocations 
and accordingly is not reopening that methodology in this 
rulemaking.\18\
---------------------------------------------------------------------------

    \16\ Under the AIM Act, by October 1 of each calendar year EPA 
must calculate and determine the quantity of production and 
consumption allowances for the following year. EPA intends to issue 
allowances for the 2024 calendar year no later than October 1, 2023, 
using the procedure established through this rulemaking.
    \17\ EPA allocated calendar year 2022 and 2023 consumption 
allowances to entities that met the criteria of 40 CFR 84.15(c)(2) 
as part of the initial pool of set-aside allowances. In the context 
of this proposal, EPA generally refers to these entities as new 
market entrants. As discussed in this section, EPA is not proposing 
to establish another pool of set-aside allowances or to extend 40 
CFR 84.15(c)(2) to future new market entrants.
    \18\ As noted previously, the existing methodology in 40 CFR 
84.13 makes application-specific allowances available to identified 
entities for calendar years 2022, 2023, 2024, and 2025. The existing 
application-specific allowance allocation methodology codified at 40 
CFR 84.13 will continue to apply as finalized in the Framework Rule. 
EPA will consider any comments on this methodology outside the scope 
of this rulemaking.
---------------------------------------------------------------------------

1. Which methodology is EPA proposing to use as the basis for 
allocations?
    EPA is proposing to base production allowance allocations on an 
entity's market share derived from the average of the three highest 
years (not necessarily consecutive) of production of regulated 
substances \19\ between 2011 and 2019. EPA is proposing to base 
consumption allowance allocations on an entity's market share derived 
from the average of the three highest years (not necessarily 
consecutive) of consumption of regulated substances between 2011 and 
2019.\20\ For new market entrants that were allocated allowances in 
2022 and 2023, EPA is proposing an approach that would allocate 
consumption allowances such that they would see an equivalent reduction 
in allowances between the 2022-2023 and 2024-2028 timeframes as general 
pool allowance holders. Since new market entrants do not receive 
allowances based on prior import history between 2011 and 2019, EPA is 
proposing to create a value that can serve as a stand in for an average 
of the three highest years of consumption of regulated substances 
between 2011 and 2019 for each new market entrant.
---------------------------------------------------------------------------

    \19\ The Agency is not, at this time, proposing to designate any 
new regulated substances under subsection (c)(3), just as the Agency 
did not designate any new regulated substances under subsection 
(c)(3) in the Framework Rule (Response to Comments on the Framework 
Rule at page 193).
    \20\ If a company did not have three years of data, EPA took the 
average of the years between 2011 and 2019 for which the company 
produced or imported HFCs, assuming the company was active in 2020 
or applied for and received special consideration (86 FR 55146).
---------------------------------------------------------------------------

    EPA would determine this based on the number of allowances 
allocated to each new market entrant in calendar year 2023 (which is 
identical to the number of allowances allocated for calendar year 2022) 
and the percent reduction all general pool allowance holders experience 
in calendar year 2023 relative to the average of their three highest 
years of consumption. For reference, each general pool allowance holder 
received allowances at a level 32.1 percent below their individual high 
three-year average in calendar year 2022. The reduction in calendar 
2023 will likely be different, assuming the number of application-
specific allowances allocated is different, and will be determined by 
October 1, 2023. EPA would divide each new market entrant's calendar 
year 2023 allowance value by the proportion of allowances received by 
general pool allowance holders relative to their high three-year 
average in calendar year 2023. For example, if general pool allowance 
holders receive allowances equivalent to 67.9 percent of their high 
three-year average identical to calendar year 2022, a new market 
entrant that received 200,000 MTEVe of allowances in 2023 would be 
credited with approximately 294,435 MTEVe as the stand in for their 
high three-year average.
    EPA would then add the high three-year average values for historic 
producers and importers with the stand in values for new market 
entrants to determine an aggregate total across all eligible allowance 
holders. This approach is intended to ensure that new market entrants 
and general pool allowance holders would experience the same 
proportionate reduction between their 2023 allocation and their 2024 
allocation. If any entity qualifies under both the new market entrant 
and historic producer or importer methodologies, the Agency will 
allocate with the methodology that issues the greater number of 
allowances. EPA is proposing that if a company that has prior 
production and/or import activity during the relevant timeframe 
acquires a new market entrant, the Agency would add the new market 
entrant's high three-year average stand-in value to the acquiring 
entity's high three-year average consumption value and would use this 
value for future allocation determinations.
    After determining entities' market share and eligibility (see 
section III.C of this preamble), EPA is proposing to then use the same 
steps as described in the Framework Rule (86 FR 55147) and codified at 
40 CFR 84.9(a)(2)-(4) and 40 CFR 84.11(a)(2)-(4) that currently apply 
for purposes of allocations for calendar years 2022 and 2023. 
Independently for production and consumption allowances, EPA would add 
every entity's average to determine a percentage market share of 
production and consumption allowances, respectively, for each entity. 
EPA would multiply each entity's percentage market share by the total 
amount of general pool calendar-year allowances available to determine 
each entity's production or consumption allocation.
    EPA is proposing to continue using historic production and 
consumption data from 2011 to 2019, matching the approach taken for 
allocating calendar year 2022 and 2023 allowances, for many of the 
reasons described in the Framework Rule (86 FR 55145-55147). Among 
these reasons is that a broad range of years such as 2011-2019 accounts 
for changes in market behavior (e.g., actively commercializing 
alternatives to high-GWP HFCs) that took place earlier in the 
transition as a result of the global agreement to the Kigali Amendment 
or other countries enacting HFC phasedown regulations.
    Beyond the rationales detailed in the Framework Rule, EPA is 
proposing to continue to use 2011-2019 data for additional reasons. 
First, using the same timeframe as finalized in the Framework Rule 
would minimize disruption to the market in 2024. EPA is seeking to 
provide a smooth transition from HFCs through the next phasedown step. 
Over the past year, allowance holders and their supply chains have been 
adjusting to the HFC Allocation Program, and more specifically, entity-
specific allocation levels. Continuing to use the same set of years 
reduces the disruption to the market. This is especially valuable since 
reducing U.S. production and import from 90 percent of baseline to 60 
percent of baseline will result in other changes to business practices, 
such as the increased use and changes in production or import of 
alternatives and reclaimed HFCs. Using the same methodology would 
provide continuity between the 2022 to 2023 timeframe and the 2024 to 
2028 timeframe, and would allow producers and importers to estimate 
their anticipated allocation and plan accordingly. Since EPA has 
already gone through the process of identifying entities' high three 
years of historic data, averaged those, and calculated respective 
market shares, entities have more specific insight on what proportion 
of available production and/or consumption allowances they would be 
allocated if EPA continued with the same methodology, although EPA does 
anticipate some entity-specific revisions due to corrected historic 
data. In comments received on the Framework Rule, EPA heard from 
regulated entities that they have long planning horizons and would 
prefer allowances be allocated consistently for as long as possible. 
Establishing a methodology for five years that continues forward an 
approach that is similar to the one used for the calendar year 2022 and 
2023 allocation provides a longer-term planning horizon for HFC 
producers and importers. This will help enable entities to make 
decisions about which HFCs, and HFC alternatives, to produce

[[Page 66378]]

and import as the market transitions away from high exchange value 
equivalent (EVe) regulated substances. Second, EPA has conducted 
multiple rounds of outreach and review and most entities have reviewed 
and corrected their data, if needed. EPA has reviewed 2011-2019 data 
against information available through other systems, such as import 
paperwork filed with U.S. Customs and Border Protection (CBP), and 
conducted outreach where significant inconsistencies were identified. 
If a significant inconsistency was identified, EPA requested entities 
correct the data or provide source materials to verify previously 
provided figures. As such, the 2011-2019 dataset is well understood and 
has received more review than any other set of years. Further, after 
implementing this approach through the Framework Rule, EPA has not 
identified any reasons that merit significantly changing course at this 
time, especially given the regulated community has recently adjusted to 
this new allocation program.
    Since the Agency is proposing to look at entity-specific data from 
such a wide range of years, EPA is proposing to average an entity's 
three highest years of data (not necessarily consecutive), as opposed 
to going with a single high year. Taking an average of multiple years 
minimizes the effect of market fluctuations and mitigates the 
possibility of an entity receiving a large share of allocations based 
on a single very high year. Using an average of the three highest years 
during the 2011-2019 period incorporates consideration of both industry 
history and ongoing growth and market change. EPA recognizes that there 
is no single year that is ``better'' for all market participants. There 
is no year in which a forward-looking entity may not have been 
stockpiling in preparation for a restriction on HFCs or new duties that 
were imposed by the Department of Commerce. Though countries agreed to 
the Kigali Amendment in 2016, efforts to amend the Montreal Protocol 
took the better part of a decade. As such, taking an average of a wider 
range of years is more equitable to all entities in the market. Each 
entity receives its ``best'' years regardless of actions taken by other 
entities.
    To determine entity-specific consumption data and an entity's three 
highest years, EPA intends to rely on production, import, export, 
destruction, and transformation data reported to the Greenhouse Gas 
Reporting Program (GHGRP),\21\ which parallels the approach taken in 
the Framework Rule and in the Agency's allocation of calendar year 2022 
general pool allowances. EPA acknowledges that the definition of 
``importer'' under GHGRP could apply to multiple entities, such that 
more than one entity could be considered an ``importer'' for purposes 
of GHGRP. As a result, entities could have played varying roles in the 
import activity, but still been appropriately considered an 
``importer'' under GHGRP definitions. Importantly, the GHGRP definition 
of importer is substantially similar to the definition of importer in 
the 40 CFR part 84 regulations.\22\
---------------------------------------------------------------------------

    \21\ The GHGRP requires various facilities and suppliers to 
annually report data related to GHGs to EPA (see 40 CFR part 98). 
Subpart OO, ``Suppliers of Industrial Greenhouse Gases,'' is the 
section relevant to reporting on HFC production and consumption. 
Because the HFCs listed as regulated substances under the AIM Act 
are industrial GHGs, EPA has collected data relevant to HFC 
production and consumption as defined under the AIM Act. Further 
discussion of the GHGRP can be found in the notices and dockets 
related to the Framework Rule.
    \22\ Compare 40 CFR 98.6 to 40 CFR 84.3.
---------------------------------------------------------------------------

    It is critical to develop an approach to allocation that helps 
ensure that only one entity receives credit as the ``entity that 
imported'' particular HFCs. For example, if both a consignee and an 
importer of record received credit for the same historically imported 
HFCs, this would double-allocate allowances for that single shipment. 
This double-allocation would distort the allowance system such that it 
was not a best available reflection of historic patterns. For purposes 
of determining historic import levels, EPA intends to rely on the 
entity that has historically reported the imports for a shipment. If 
two or more entities report the same import to GHGRP, EPA would include 
that import in the allowance allocation calculation of the entity that 
first reported the import to GHGRP. EPA considers historic reporting to 
GHGRP as indicative of the entity that took primary responsibility for 
complying with EPA requirements for that import and considers this a 
critical data point to determining who to credit that import to. EPA is 
concerned that entities who took limited if any responsibility for the 
import, including complying with EPA reporting requirements, may 
attempt to claim that they are in fact the importer now that EPA has 
begun implementing the AIM Act.
    EPA is also considering whether to include more recent data in 
determining allocation levels given that more recent data may be a more 
accurate reflection of the current state of the HFC production and 
import market. EPA requests comment on whether to expand the range of 
years to use to develop each allowance holder's high three-year average 
to include 2020 and 2021. EPA has not included these years in its 
primary proposal because the Agency recognizes that production and 
importation of HFCs in 2020 and 2021 were likely influenced by external 
factors such as the COVID-19 pandemic, and supply chain disruptions. In 
addition, EPA is concerned that data from 2020 and 2021 could be 
distorted due to an entity's awareness that the AIM Act may be, or had 
been, passed. Data from 2021, in particular, may be skewed given the 
likelihood of stockpiling in advance of the Framework Rule becoming 
effective and the associated restrictions on production and import of 
regulated substances that began on January 1, 2022. Expanding the range 
of years could also significantly change each entity's market share, 
which could disrupt the market and negatively affect ongoing 
adjustments to the HFC Allocation Program that have taken place in 2022 
and 2023. Further, EPA is unaware of any environmental benefit 
associated with changing the years used to determine allowance 
allocations. For the reasons described, EPA's primary proposal is to 
not use 2020 and 2021 data to determine entity-specific allocation 
amounts. However, EPA requests comment on whether there are advantages 
and disadvantages of including 2020 and 2021 data, and if so, what 
those would be.
    EPA is proposing to include data that dates as far back as 2011 
because of potential concerns that data from more recent years, 
particularly 2017-2021, could reflect attempts at market manipulation, 
stockpiling, or other system gaming by some entities that were aware of 
agreement of the Kigali Amendment to the Montreal Protocol on October 
15, 2016, and/or development and consideration of the AIM Act by 
Congress. By using only later years of data, and not data from the 
earlier timeline, EPA could potentially unfairly give additional weight 
to entities that had inflated numbers due to attempts at artificial 
market positioning or stockpiling behavior ahead of the HFC phasedown.
    EPA also considered using a rolling set of years, such as 
allocating based on entities' prior three years of production or 
consumption data, but decided against proposing this as an option. 
Using a rolling average based on the most recent production or 
consumption data would allow allocations for additional new entrants 
beyond entities that are allocated allowances based on historic 
production and import and as new market entrants from the set-aside 
pool. Under EPA's Framework Rule, 40

[[Page 66379]]

CFR 84.15, and our primary proposal in this rule, any entity that did 
not receive allowances as a new market entrant to import going forward 
or that lacked production or import history from 2011-2019, would have 
to purchase allowances from an entity willing to engage in a transfer. 
As currently established, each transfer is a one-off transaction that 
only applies to the year of the transfer. Unless an entity acquires a 
different entity that holds allowances outright and receives a regular 
allocation, this approach does not allow for an entity to secure 
allowances for the duration of the allocation period. However, there 
are many advantages of using a stable set of past years instead of 
using more recent data, especially data from after the start of the HFC 
Allocation Program. Many stakeholders have expressed concerns that if 
EPA were to base allocations on production and import volumes in 2022 
and later years, entities that transferred their allowances would 
effectively reduce their market share and receive fewer allowances in a 
future allocation. Likewise, entities that receive allowances through 
an inter-company transfer would be gaining market share that could 
increase their future allocation. In the proposal prior to the 
finalized Framework Rule (86 FR 27203, May 19, 2021), EPA sought 
advance input on what approaches to consider for 2024 and later years, 
indicating that the methodology used to determine allowance allocations 
for calendar years 2022 and 2023 may not be used for the 2024 
allocation. Uncertainty about whether EPA may decide to allocate future 
allowances on the basis of data from a rolling set of years rather than 
from a fixed historical period may have contributed to reluctance from 
some allowance holders to engage in transfers. This uncertainty would 
be resolved over the intermediate future if EPA finalizes the approach 
of continuing to use historic production and consumption data to 
determine allowance allocations for calendar years 2024 through 2028. 
Transfers are important for an efficiently functioning market and 
ensuring the opportunity for full utilization of allowances. Basing 
allowance allocations on data from a rolling set of years during this 
timeframe could promote uncertainty among allowance holders and inhibit 
the efficient transfer of allowances. EPA is concerned about finalizing 
an allocation methodology that would disincentivize transfers unless 
there were other compelling reasons to argue for such a methodology and 
is therefore not proposing to use a rolling set of years to determine 
entity-specific allocation amounts for the 2024 through 2028 
allocations.
2. What other allocation methodologies did EPA consider?
    As indicated in the proposal to the Framework Rule (86 FR 27150), 
including in the section seeking advance comment to inform future 
rulemakings, EPA has been considering other ways to undertake allowance 
allocation beyond allocating allowances to entities based on historic 
production and import activity at no cost (86 FR 27203). In considering 
different allocation mechanisms, EPA considered multiple factors, 
including ease of implementation for both the regulated community and 
the U.S. government; consistency with the AIM Act; facilitating an 
efficient market, such as by collecting and releasing data on 
production, import, and inventories of HFCs; transparency and certainty 
for regulated entities and the public; distributional effects, such as 
on new entrants; responsiveness to changing market conditions (e.g., 
companies entering or existing the market, corporate mergers and 
acquisitions, significant quantities of allowances unexpended at the 
end of the year, or supply shortages or market disruptions for specific 
HFCs); small business implications; minimizing the opportunity for 
fraud; and other factors.
    In developing this proposed rulemaking, the Agency considered 
charging a fee for allowances or establishing a system to auction 
allowances. These approaches have advantages, including returning value 
to taxpayers and setting a visible price signal, which could provide 
useful price information for the public and for market participants. A 
fee or auction would be aimed at further incentivizing the highest 
economically valued use due to the upfront expenditures needed for all 
entities seeking allowances to produce and import HFCs. There is 
extensive literature discussing the conditions where auctions may be 
more suitable than other allocation methods.\23\ The academic 
literature indicates that auctions may have potential advantages in 
addressing challenges such as new entrants, ensuring efficient and 
equitable allocations as market conditions change, and encouraging 
competition and innovation.\24\ Both EPA, and the federal government 
overall (for example, the Federal Communication Commissions' spectrum 
auctions and the U.S. Treasury Department's sealed pay as bid and 
uniform bid auctions on debt of various maturities), have experience 
administering auctions of various formats.

Recommendation 2017-4: Marketable Permits (2017), https://www.acus.gov/sites/default/files/documents/Recommendation%202017-4%20%28Marketable%20Permits%29.pdf (citing relevant literature, 
including the consultant's report, which further summarizes the 
literature, available at https://www.acus.gov/sites/default/files/documents/Marketable%20Permits%20Report-final.pdf).
    \24\ The 2017 review conducted by the Administrative Conference 
of the United States also notes that ``even when an agency has 
statutory discretion to use [an auction] program, such a program may 
not be the most suitable regulatory tool to achieve an agency's 
goal.'' See https://www.acus.gov/sites/default/files/documents/Recommendation%202017-4%20%28Marketable%20Permits%29.pdf.
---------------------------------------------------------------------------

    However, EPA also anticipates challenges with establishing a 
potential fee-based or auction system and is not proposing to use these 
methods of allocation in this proposed rulemaking. EPA and regulated 
entities have experience implementing the allocation methodology set 
for the calendar years of 2022 and 2023, which is similar to the system 
that many entities also participated in for the phaseout of ODS under 
Title VI of the Clean Air Act (CAA).\25\ Creating and administering a 
different system would result in additional burden on EPA and 
uncertainty for those involved in the early stages of the HFC 
phasedown. EPA is also concerned that smaller entities with less 
available capital may not be able to bear the initial costs of 
purchasing allowances either through a fee system or through an 
auction. EPA would also need to consider what safeguards would be 
appropriate to deter or prevent efforts by well-capitalized entities, 
particularly in an auction system, to artificially corner a portion of 
the HFC market for their overall business gains.
---------------------------------------------------------------------------

    \25\ A key difference between the phaseout of ODS and this 
program is that consumption and production of HFCs will not be 
phased out entirely.
---------------------------------------------------------------------------

    For these reasons, EPA is not proposing to establish a fee-based or 
auction system to allocate allowances in this proposed rule. These 
considerations may change as the phasedown proceeds. EPA recognizes 
that the market may face scarcity as HFC production and consumption is 
phased down, and we may also see allowances unused as new alternatives 
not subject to allocations replace HFCs. The use of an EV-weighted 
system rather than chemical-by-chemical allocation in part addresses 
these different market forces by providing flexibility about which HFCs 
are produced and imported. EPA intends to consider all relevant 
information when developing future rulemaking. To facilitate our 
continued

[[Page 66380]]

consideration, separate and apart from this current rulemaking, EPA 
invites advance comments on whether there are any current or potential 
future disadvantages with the currently proposed allocation system that 
could be addressed by an alternate allocation mechanism, as well as 
comments on design features or timing options for alternate allocation 
mechanisms that EPA could consider were the Agency to determine at a 
future point that changes are warranted.
3. What did EPA consider in developing its proposal as to the 
appropriate entities to be allocated allowances?
    As outlined in section III.B.1 of this preamble, EPA is proposing 
to use a similar methodology to calculate allocation quantities as the 
initial framework used for allocating calendar year 2022 and 2023 
production and consumption allowances, with adjustments to accommodate 
new market entrants that received allowances from EPA on March 31, 
2022. In developing this proposed approach, EPA has considered whether 
to allocate production and consumption allowances to entities beyond 
those that have historic production and import data.
    As part of this deliberation, EPA has considered whether allowance 
allocations can be used to incentivize certain behavior such as to 
maximize reclamation and minimize releases of regulated substances. 
Some commenters to the Framework Rule encouraged EPA to issue 
allowances to reclaimers. The result of this suggestion could be that 
reclaimers have allowances available to directly import virgin 
regulated substances that they could use to rebalance refrigerant 
blends that are slightly off specification after reprocessing recovered 
refrigerant. The allowances could be transferred to another entity to 
import or produce on the reclaimer's behalf, or could be used to ease a 
reclaimer's ability to purchase regulated substances from another 
entity. This could be an indirect way to foster the development of HFC 
reclamation operations. However, EPA notes that reclaimers that have 
historically directly imported were included in the Framework Rule 
methodology and would be included under the primary proposed 
methodology for this rule. EPA notes as well that several reclaimers 
applied for, and received, new market entrant allowances from the set-
aside pool for calendar years 2022 and 2023. EPA does not view issuing 
allowances to reclaimers that are not eligible based on the methodology 
EPA is proposing to use for 2024 through 2028 (i.e., similar to the 
methodology used for 2022 and 2023 including the additional allowances 
issued to new market entrants) as a meaningful way to increase 
opportunities for reclamation and recognizes that by doing so, EPA 
would reduce the number of allowances available to other market 
participants including other reclaimers. Moreover, EPA is exploring 
options to promote reclamation under other sections of the AIM act 
(e.g., under subsection (h) Management of regulated substances). 
Further, the phasedown of HFCs increases opportunities for use of 
reclaimed HFCs by restricting the amount of newly produced and imported 
HFCs that can enter U.S. commerce.
    As noted previously in this section, EPA is not proposing to 
establish a set-aside pool of allowances for calendar years 2024 
through 2028. In the Framework Rule, EPA created a set-aside pool of 
allowances to be allocated no later than March 31, 2022. The prior set-
aside pool was created for three types of entities: application-
specific allowance holders, historic importers that were under the 
GHGRP reporting threshold and did not receive general pool allowances, 
and new market entrants. The first two categories were created for 
entities that may not have known of or fully understood the regulatory 
system created in the Framework Rule given that the Agency undertook 
the rulemaking in 270 days at Congress's direction and was implementing 
a program under a new statute. This concern is no longer applicable. 
Under 40 CFR part 84, entities are required to expend allowances for 
import and production of regulated substances as of January 1, 2022; 
therefore, EPA anticipates that entities active in the HFC market are 
now well aware of EPA's HFC phasedown program. The third group eligible 
for set-aside allowances was new market entrants. EPA determined in the 
Framework Rule it was appropriate to exercise its discretion to create 
a small set-aside pool of allowances for entities looking to enter the 
HFC import market. It was appropriate to consider this as a one-time 
opportunity at the initiation of the HFC phasedown program. EPA is not 
privy to individual entities' decisions on whether to apply for new 
market entrant allowances, but entities were provided notice of the 
opportunity and many applied. While the number of consumption allowance 
holders doubled from the initial allocation with the addition of the 
eligible new market entrants, these new entrants hold a small 
percentage of the overall number of allowances issued. EPA recognizes 
that the goal of the AIM Act is to establish a national phase down of 
HFC production and consumption by 85 percent by 2036, and therefore, 
while the Agency did offer this one-time opportunity, EPA does not view 
further allocations for a set-aside pool and/or allowances for entities 
who have not previously produced and imported HFCs as supporting the 
AIM Act's objectives.

C. How is EPA accounting for past production or import activity to 
determine allocation eligibility?

    In order to be eligible to receive general pool allowances for 2024 
through 2028 based on historic production and import activity (i.e., 
for entities that produced and imported regulated substances in 2011 
through 2019), EPA is proposing that an entity must have produced (for 
production and consumption allowances) or imported (for entities only 
receiving consumption allowances) HFCs in 2021 or 2022. EPA had a 
similar requirement in the Framework Rule, specifically requiring 
production or import in 2020.\26\ This additional eligibility 
requirement, that an entity has demonstrated import or production 
activity in recent years, is intended to exclude entities from 
receiving allocations that are no longer undertaking the activities for 
which allowances are required. EPA is interested in avoiding allocating 
to entities that had historic import or production data in the 2011-
2019 timeframe, and have since ceased operations or transitioned away 
from HFC production or import. Allocating allowances to entities that 
cannot or will not use them could be disruptive to the market during 
the phasedown if allowances go unexpended or could result in windfall 
profits to an entity that will only use the allowances to transfer for 
a price. The practical effect of not allocating allowances to an entity 
due to their inactivity would be a pro rata increase of allocation 
levels to other entities receiving allowances from the general pool 
allocation.
---------------------------------------------------------------------------

    \26\ EPA also allowed for an entity to identify individual 
circumstances for not importing in that year due to the COVID-19 
pandemic, which is no longer applicable. EPA is not proposing a 
mechanism to allow an entity to request unique consideration if they 
did not produce or import in 2021 or 2022.
---------------------------------------------------------------------------

    Relying on information from 2021 or 2022 would incorporate more 
recent activity than was used for the calendar year 2022 and 2023 
allocations, which required production or import in 2020,

[[Page 66381]]

or for purposes of allocating consumption allowances, an entity to 
identify individual circumstances for not importing or producing in 
2020, given that it was an unusual year due to the COVID-19 pandemic. 
Allowing two years, as opposed to a single year, provides additional 
time to demonstrate activity in the market, and is intended to reduce 
the impacts of supply chain delays, temporary changes in demand, or 
other business decisions. Some entities also import small volumes of 
HFCs and may not need to import every year. EPA is proposing to use a 
fixed set of years (i.e., 2021 and 2022) to determine eligibility for 
entities to be allocated allowances for calendar years 2024 through 
2028 to provide a degree of clarity and certainty to entities during 
this period in order to minimize disruption to existing supply chains 
that have adjusted to the 2022 and 2023 allowance allocations. If this 
approach is finalized as proposed, all market participants will be able 
to generally understand their own and other allowance holders' market 
share for the 2024 through 2028 period as of October 1, 2023, because 
there would not generally be shifts in how many entities EPA is 
allocating allowances to and the relative share of allowances going to 
those entities. EPA considered proposing to use a rolling set of years 
to confirm activity, but using a rolling set of years would not provide 
the same stability since allowance holders could come into and out of 
the allocation system, hereby affecting everyone's relative share of 
available allowances. EPA also does not want to incentivize entities in 
each subsequent rolling set of years' entities to continue importing or 
producing small quantities that would otherwise be outside the entity's 
plans in future years just to maintain position to receive future 
calendar year HFC allowances. Looking to behavior in 2021 or 2022 would 
also have administrative benefits to EPA. For example, determining 
annual allocations would be more streamlined because EPA would be 
relying on data that has been vetted and reviewed at a single point in 
time that is in advance of the calendar year 2024 allocation as well as 
all allocations through calendar year 2028.
    EPA's primary proposal is to not apply this eligibility criteria 
for new market entrants, and instead allocate allowances to all new 
market entrants as described in section III.B.1 of this preamble, but 
EPA is considering and taking comment on whether EPA should require 
that new market entrants import in 2022 to be eligible for allocation 
of allowances for calendar years 2024 through 2028. Most new market 
entrants are, as their name suggests, new to the HFC import market and 
would not reasonably be expected to have any import activity in 2021. 
Therefore, if the Agency applies eligibility criteria to new market 
entrants at all, it seems reasonable to look to 2022 for import 
activity. Accordingly, for these entities, EPA would not be able to 
look across two years for import for most new market entrants, unlike 
for general pool participants. EPA anticipates that most new market 
entrants would make use of allocated allowances and import regulated 
substances in 2022, so it may be reasonable to look for this action to 
determine whether the new entrants did in fact enter the market and if 
they should maintain future eligibility. On the other hand, EPA 
previously recognized that new market entrants might have difficulty 
operationalizing their business to begin importing regulated substances 
in 2022 if the entity was fully new to this aspect of the import 
business. As a result, in the Framework Rule the Agency took the 
position that EPA would ``not reduc[e] allowances to new market 
entrants in 2023 for failing to use all the allowances issued in 
2022,'' (86 FR 55159).
    If the approach to determining eligibility for general pool 
allowances from 2024 through 2028 is finalized as proposed, for 
purposes of determining whether an entity imported or produced 
regulated substances in 2021, the Agency intends to rely on data that 
have been reported to EPA under the GHGRP.\27\ Entities who imported 
HFCs in quantities below the GHGRP reporting threshold (i.e., 25,000 
MTCO2e for the year) who wish to be considered for 
allowances, should report their import and export activity data through 
the electronic Greenhouse Gas Reporting Tool (e-GGRT) no later than the 
close of the comment period on December 19, 2022. EPA will not consider 
data submitted after this date for purposes of issuing allowances under 
the AIM Act for 2024 and later years. For purposes of determining 
whether an entity imported or produced regulated substances in 2022, 
EPA intends to rely on data that have been reported pursuant to the 40 
CFR part 84 requirements. EPA intends to rely on data reported no later 
than February 14, 2023, which aligns with the reporting deadline for 
fourth quarter calendar year 2022 HFC reports under the HFC allocation 
requirements at 40 CFR part 84, subpart A.\28\ Further, EPA is 
proposing that in cases where allowances were not expended at the time 
of production and/or import of HFCs in 2022, that production and import 
would not count as activity in 2022 for eligibility purposes. In other 
words, for 2022, EPA would only consider production and import of HFCs 
where allowances were expended as required when determining whether an 
entity is eligible for allowances. EPA has established a GHGRP Help 
Desk to assist potential reporters with issues related to registering 
and electronic reporting. The hotline can be reached at 
[email protected] or 1-877-444-1188 (toll free).
---------------------------------------------------------------------------

    \27\ In the limited situations where data on certain HFCs are 
not required to or cannot be reported to the GHGRP, e.g., production 
of HFC-23 that is created during production of HCFC-22, EPA would 
continue to rely on verified submissions from entities no later than 
the close of the comment period on December 19, 2022.
    \28\ For more information, visit https://www.epa.gov/climate-hfcs-reduction/hfc-allocation-rule-reporting-and-recordkeeping.
---------------------------------------------------------------------------

    Alternatively, EPA is taking comment on simply basing allocations 
on historic reported data between 2011 and 2019, without including an 
additional eligibility requirement relating to whether the entity 
produced or imported HFCs in recent years, such as 2021 or 2022. As 
noted previously, EPA is concerned that this approach would result in 
allocating to entities that are no longer in the HFC production or 
import business, and may no longer be in business at all.

D. Can allowances be transferred or conferred prior to the calendar 
year?

    EPA is proposing to clarify that entities may confer or transfer 
allowances at any point after they are allocated until the allowance 
expires at the end of the calendar year for which it was allocated. 
Allowances can only be expended to cover imports or production in the 
calendar year for which they are allocated, but entities can confer or 
transfer allowances before January 1 of the calendar year. 40 CFR 
84.5(d) provides that all production, consumption, and application-
specific allowances are valid only for the calendar year for which they 
are allocated (i.e., January 1 through December 31). The intent of this 
provision was to state that allowances could only be expended in the 
calendar year for which they were issued. However, use of the term 
``valid'' could be read as ambiguous with regard to whether it allows 
for transfers and conferrals before the calendar year. EPA is proposing 
to amend this prohibition to more clearly state that entities may 
transfer and confer their allowances upon their allocation, including 
ahead

[[Page 66382]]

of January 1 of the calendar year for which the allowances were 
allocated.
    The Agency hopes that this added clarity would facilitate allowance 
holders' planning for that upcoming year. EPA encourages allowance 
holders to undertake transfers and conferrals early in the year and, 
where possible, well in advance of when regulated substances would need 
to be produced or imported. Under the existing 40 CFR part 84 
regulations, the entity that is producing or importing the regulated 
substances must have the allowances in their possession as required 
(see section V.A of this preamble) and at the time that allowances are 
required to be expended.

IV. How is EPA proposing to update the consumption baseline?

    This section explains how EPA determined the consumption baseline 
in the Framework Rule, how it proposes to update the baseline, and how 
it plans to further update associated data. Subsection (e)(1) of the 
AIM Act directs EPA to establish a production baseline and a 
consumption baseline and provides the equations for doing so. In the 
Framework Rule, EPA calculated and codified the production and 
consumption baselines according to the formulas outlined in subsection 
(e)(1) of the AIM Act. After EPA finalized these baselines, a company 
informed EPA that they had misreported data previously reported to EPA 
that factors into the consumption baseline. EPA is now proposing to 
update the consumption baseline and associated phasedown schedule with 
this corrected dataset. Separate and in parallel to this action, EPA is 
also providing a final opportunity for entities to revise their HFC 
data from 2011 through 2021 for purposes of issuing allowances under 
the AIM Act.

A. How did EPA determine the consumption baseline in the Framework 
Rule?

    The AIM Act instructs EPA to calculate the consumption baseline by, 
among other things, using the average annual quantity of all regulated 
substances consumed in the United States from January 1, 2011, through 
December 31, 2013. EPA used multiple sources of data to calculate HFC 
consumption figures for 2011 through 2013: (1) Data reported to EPA's 
GHGRP; (2) data received in response to the notice of data availability 
published February 11, 2021 (86 FR 9059); (3) data from the Automated 
Commercial Environment (ACE) and confirmed through letters sent out 
under CAA section 114 (EPA ICR 2685.01); and (4) data received in 
response to the notice of proposed rulemaking for the Framework Rule by 
the comment due date. Through these sources, EPA received new or 
revised production, import, export, and destruction data, all of which 
affected the final baseline values. Based on the data reviewed and 
collected through these robust efforts, EPA codified the final 
consumption baseline as 303,887,017 Metric Tons of Exchange Value 
Equivalent (MTEVe) (40 CFR 84.7(b)(2)). A complete description of EPA's 
process in developing the codified baseline figure can be found in the 
Framework Rule at 86 FR 55137--55142.
    In subsection (e)(2)(C) of the AIM Act, Congress provided the HFC 
phasedown schedule measured as a percentage of the baseline. In the 
Framework Rule, EPA codified this phasedown schedule at 40 CFR 84.7(a). 
EPA also codified the total production and consumption in MTEVe for 
regulated substances in the United States in each year by multiplying 
the finalized production and consumption baselines by the percentages 
of the phasedown schedule. EPA codified total production and 
consumption allowance quantities that could be allocated at 40 CFR 
84.7(b)(3).

B. How is EPA proposing to adjust the consumption baseline?

    After EPA finalized the Framework Rule, one company informed EPA 
that the 2011 and 2012 HFC import data that it had reported to the 
GHGRP and certified per 40 CFR 98.4(e)(1) as true, accurate, and 
complete under penalty of law, was, in fact, significantly more than 
its actual import quantities. Because EPA used the company's 2011 and 
2012 HFC import data in the calculation of the consumption baseline, 
the Agency's calculated and codified consumption baseline was high. The 
company has since submitted and certified revised reports. EPA has 
verified the amended data by reviewing the importer's invoices and 
comparing the reported data to import data provided by CBP. EPA is 
proposing to update the codified consumption baseline with the 
corrected data. Specifically, EPA is proposing to revise the 
consumption baseline from 303,887,017 MTEVe to 300,257,386 MTEVe, which 
is a decrease of 3,629,631 MTEVe to account for this error. Because the 
erroneous data related only to imports, the Agency's previously 
calculated production baseline is not affected and EPA is not proposing 
to reopen the production baseline in this rulemaking. There are only 
nine known HFC production facilities and given EPA's experience with 
these reporters, the Agency does not expect that there are material 
errors in their data submissions from the 2011-2013 timeframe.
    The proposed revision of the baseline amounts to about a one 
percent change in the baseline. This is not an insignificant 
difference, but once EPA applies the relevant phasedown step to the 
baseline and then allocates the resulting allowances among eligible 
recipients, the change in baseline is expected to have a small effect 
on individual entities' allocations. Further, this revised baseline, if 
finalized, would start affecting allowance allocations for calendar 
year 2024. Because of the prior framing of EPA's regulations, 
specifically the fact that there was no prior allocation methodology 
that would apply to calendar year 2024 allowances and beyond, no 
entities should have had a realistic expectation of allowance 
allocation levels. Therefore, EPA expects that this alteration of 
baseline would not affect the regulated communities' reasonable 
reliance interests.
    As outlined in section IV.C of this preamble, EPA is going through 
a process under the AIM Act to provide a final opportunity for entities 
to confirm, and if necessary correct, the data available to EPA on 
those entities' historic consumption activities to inform future 
allocation calculations. Should other entities identify misreporting in 
2011 through 2013 through that process, and sufficiently certify and 
verify the corrected numbers to EPA, the Agency would include those 
revised figures in the proposed revision to the consumption baseline in 
addition to the revision outlined in the prior paragraph.
    Data that are submitted under the GHGRP in e-GGRT already have 
undergone a variety of verification checks during and after report 
submission. Facilities are sent messages about potential errors in 
their report; they can either reply with an explanation of the unusual 
values, or they can resubmit their report to correct any errors and 
certify the accuracy of the submission. EPA may also request copies of 
bills of lading, invoices, or CBP entry forms in order to verify 
reports.
    In 2021 in order to verify accurate data for calculation of the AIM 
Act baseline and allocation of allowances, EPA compared import data 
submitted to GHGRP to import data from CBP as an additional form of 
verification. If the sum of metric tons of HFCs reported to e-GGRT 
diverged significantly from the sum of metric tons of imports under 
HFC-related Harmonized Tariff Schedule (HTS) codes in CBP records,

[[Page 66383]]

these submissions were flagged for possible issues. The Agency 
generally contacted each facility that was flagged requesting that they 
either:
     Provide documentation (e.g., bills of lading, invoices, 
and/or CBP Entry Forms substantiating their imports), or
     Resubmit their report to GHGRP to correct potential errors 
that would account for why the reported GHGRP data did not more closely 
align with data reported to CBP.
    EPA staff reviewed resubmitted reports and supporting 
documentation. Any issues found in the documentation review resulted in 
additional messages sent to the facility to verify reported data. 
Additional steps taken to verify the data include quality assurance 
reviews by EPA staff and steps to confirm corporate or common ownership 
of reporting entities for each allowance holder.
    Revising the consumption baseline would change the total 
consumption cap in MTEVe for regulated substances in the United States 
in each year after the revision takes effect. In subsection (e)(2)(C) 
of the AIM Act, Congress provided the HFC phasedown schedule measured 
as a percentage of the baseline, which EPA codified at 40 CFR 84.7(a). 
EPA also codified the total production and consumption in MTEVe for 
regulated substances in the United States in each year by multiplying 
the finalized production and consumption baselines by the percentages 
of the phasedown schedule. Therefore, EPA proposes to revise the table 
of production and consumption limits at 40 CFR 84.7(b)(3) by replacing 
the current values in Table 2, column 3 of this preamble with the 
values in column 4.

    For additional context and transparency, we note that separate from 
this rulemaking process, EPA has recalculated the number of allowances 
that should have been allocated to the company that had reported 
erroneous data. EPA took administrative consequences to retire portions 
of that company's allocated calendar year 2022 and 2023 consumption 
allowances equal to the difference between the allocation level based 
on the updated historical import data and what was previously 
calculated by the Agency based on misreported data.

C. What other opportunities is EPA providing to further update data?

    Separate from this action, EPA is providing a final opportunity for 
entities to verify, and if necessary correct, the data available to EPA 
on those entities' historic consumption activities from 2011 through 
2021 for purposes of the AIM Act. EPA sent an electronic communication 
or letter to all entities that were known, or likely, to have had 
consumption activity of regulated substances from 2011 through 2021 
that they had until September 26, 2022, to verify, and if necessary 
correct, the data available to EPA on those entities' historic 
consumption activities from 2011 through 2021.\29\ EPA is providing 
this final opportunity to entities to make any corrections to historic 
data; after this point, EPA does not intend to consider any data 
revisions in allocation decisions.\30\
---------------------------------------------------------------------------

    \29\ This request was for purposes of implementing the AIM Act. 
Nothing in this letter or in the complementary process described 
below relieves any entity of obligations under the GHGRP regulations 
codified in 40 CFR part 98.
    \30\ These revisions would be taken into account when 
determining the annual allocation issued by October 1 of each year 
for 2024 and future year allocations. If information reveals an 
entity has provided false, inaccurate, or misleading information, 
EPA reserves the right to issue administrative consequences to 
adjust allowances downward (in the same year or a subsequent year). 
Regardless of whether or not EPA applies an administrative 
consequence, EPA may also pursue any and all appropriate enforcement 
action.
---------------------------------------------------------------------------

    If there is any entity that did not receive a letter or electronic 
communication from EPA that had consumption activity of regulated 
substances from 2011 through 2021, EPA is hereby providing notice that 
for the purposes of future HFC allowance allocations under the AIM Act, 
EPA will not consider any data unless submitted to EPA through e-GGRT 
by the close of the comment period on December 19, 2022. To allow EPA 
to verify the reported data in a timely manner, anyone reporting past 
consumption data for the first time must provide transactional records 
(e.g., bills of lading, invoices, or CBP entry forms). Failure to 
provide EPA with sufficient documentation at the time of submission to 
verify these reports may prevent EPA from considering the data in 
allowance allocations.
    This final opportunity for AIM Act purposes would help ensure that 
allowance allocations are based on the most accurate data available. 
EPA notes that entities may be referred to EPA's enforcement office for 
potential reporting violations under the CAA and EPA may issue 
administrative consequences to adjust 2022 and/or 2023 allowances where 
appropriate.

V. How is EPA proposing to revise requirements related to allowances 
for import?

    EPA is proposing to make amendments that codify our existing 
practice for determining which calendar year allowances must be 
expended for an import as well as who can expend allowances. 
Additionally, EPA is proposing to specify the requirements for the 
importation of heels \31\ when the precise quantity remaining is 
uncertain. EPA is making these proposals based on the experience gained 
in implementing the HFC phasedown program to date under the existing 40 
CFR part 84 regulations and establishing a system for consistent 
implementation and enforcement.
---------------------------------------------------------------------------

    \31\ ``Heel'' is defined at 40 CFR 84.3 as ``the amount of a 
regulated substance that remains in a container after the container 
is discharged or offloaded (that is no more than 10 percent of the 
volume of the container).'' EPA views this as an amount that is no 
more than 10 percent by weight of the amount of that same substance 
that is typically sold in a ``full'' container of that size. For 
example, if a ``full'' cylinder of HFC-134a typically contains 25 
pounds of HFC-134a, then 2.5 pounds or less of HFC-134a remaining in 
the cylinder would be considered a heel.

---------------------------------------------------------------------------

A. Codifying the Point in Time That an Allowance Must Be Expended to 
Import Regulated Substances

    Currently in 40 CFR 84.5(b)(1)(i) EPA prohibits persons from 
importing bulk \32\ regulated substances except, among other conditions 
and with limited exceptions, ``[b]y expending, at the time of the 
import, consumption or application-specific allowances in a quantity 
equal to the exchange value-weighted equivalent of the regulated 
substances imported.'' Through implementing the HFC allocation system, 
EPA has described the exact point in time used to determine which 
calendar year allowance would need to be expended for each import of a 
regulated substance. EPA has spoken explicitly to this issue, including 
through a December 21, 2021, post on our HFC phasedown Frequently Asked 
Questions web page.\33\ EPA stated that a marine vessel waiting off the 
coast of the United States in December 2021, that berthed in January 
2022, would be required to expend a calendar year 2022 allowance for 
any HFCs that berth at a port in the United States in 2022. EPA is 
proposing to incorporate this previously stated interpretation into the 
40 CFR part 84 regulatory text. Providing specificity on this point in 
the regulations would help ensure consistent and accurate accounting 
associated with allowance use for all importers.
---------------------------------------------------------------------------

    \32\ ``Bulk'' is defined at 40 CFR 84.3 as ``a regulated 
substance of any amount that is in a container for the 
transportation or storage of that substance such as cylinders, 
drums, ISO tanks, and small cans. A regulated substance that must 
first be transferred from a container to another container, vessel, 
or piece of equipment in order to realize its intended use is a bulk 
substance. A regulated substance contained in a manufactured product 
such as an appliance, an aerosol can, or a foam is not a bulk 
substance.''
    \33\ EPA. Phasedown of Hydrofluorocarbons Final Rule Frequently 
Asked Questions. https://www.epa.gov/climate-hfcs-reduction/phasedown-hydrofluorocarbons-final-rule-frequently-asked-questions.
---------------------------------------------------------------------------

    The AIM Act and EPA's implementing regulations define ``import'' 
\34\ broadly to mean:
---------------------------------------------------------------------------

    \34\ The definition of ``import'' is intended to allow for 
effective implementation of the AIM Act's HFC phasedown provisions 
and does not, nor was it intended to, match CBP's definition. The 
definition of ``import'' is similar to, but different from, the 
definition of ``date of importation,'' which is a CBP defined term 
and is discussed later in section VI.A.1 of this preamble.

to land on, bring into, or introduce into, or attempt to land on, 
bring into, or introduce into, any place subject to the jurisdiction 
of the United States, regardless of whether that landing, bringing, 
or introduction constitutes an importation within the meaning of the 
customs laws of the United States. Offloading used regulated 
substances \35\ recovered from equipment aboard a marine vessel, 
aircraft, or other aerospace vehicle during servicing is not 
considered an import.
---------------------------------------------------------------------------

    \35\ EPA defines ``used regulated substances'' (or used HFCs) in 
40 CFR 84.3 as ``regulated substances that have been recovered from 
their intended use systems (including regulated substances that have 
been, or may be subsequently, recycled or reclaimed).''

EPA is not proposing to amend this regulatory definition given that it 
matches the definition provided by Congress in the AIM Act. However, 
EPA is proposing a specific regulatory definition of when an allowance 
must be expended for the import of bulk regulated substances. Under 
this proposed approach, EPA would revise the prohibition language in 40 
CFR 84.5(b)(1)(i) to remove the point that an allowance must be 
expended ``at the time of import'' and instead require that an 
allowance be expended at the time of ship berthing \36\ for vessel 
arrivals, border crossing for land arrivals such as trucks, rail, and 
autos, and first point of terminus in U.S. jurisdiction for arrivals 
via air.
---------------------------------------------------------------------------

    \36\ EPA has and continues to interpret berth to mean ``to moor 
(a ship) in its allotted place at a wharf or dock.''
---------------------------------------------------------------------------

    If EPA were to finalize this proposed regulatory revision, EPA 
proposes to also require that the importer of record for the purposes 
of compliance with the final rule be in possession of allowances in the 
amount that will need to be expended at the time of filing their 
advance report under 40 CFR 84.31(c)(7). As explained in the Framework 
Rule, this advance notice reporting requirement is intended to allow 
``EPA to verify if allowances are available or the HFCs have prior 
approval for import in the case of HFCs imported for destruction or 
transformation under 40 CFR 84.25, or imported for transshipment under 
40 CFR 84.31(c)(3), and confirm whether a shipment should be allowed to 
clear Customs or not'' (86 FR 55186). If an entity does not possess 
requisite allowances for the import of bulk regulated substances at the 
time of the advance notice reporting, EPA will not be able to verify if 
allowances are available and whether the shipment meets EPA's HFC 
requirements to be released from CBP's custody. Given that advance 
reporting is required, no later than fourteen days \37\ before 
allowances must be expended, EPA does not anticipate this proposed 
requirement would be a burden on regulated entities and would have 
significant benefits for EPA implementation and enforcement efforts.
---------------------------------------------------------------------------

    \37\ Currently under EPA's regulations, importers are required 
to provide advance notification of import no later than 14 days 
prior to import. As explained in a subsequent section, EPA is 
proposing to modify and take comment on these requirements based on 
the mode of transportation.
---------------------------------------------------------------------------

    For context, the point in time that a vessel berths, a truck 
crosses the border or the first point of terminus in U.S. jurisdiction 
for planes may be reflected as the ``Conveyance Arrival'' date for 
shipments, which importers or their brokers with access to the 
Automated Broker Interface (ABI) may find through an ACE Cargo 
Manifest/In-Bond/Entry Status Query. However, regardless of the date 
identified in ABI as the ``Conveyance Arrival,'' it is the importer's 
obligation, or it would be the importer of record's obligation as 
proposed in this rulemaking and discussed below in section V.B of this 
preamble, to ensure that it has expended the appropriate calendar year 
allowances in the appropriate quantity to align with regulatory 
requirements.
    The Framework Rule at 40 CFR 84.5(b)(1)(i) prohibits the 
importation of bulk regulated substances without expending the required 
allowances, with limited exceptions. Since the definition of ``import'' 
in the AIM Act and the 40 CFR part 84 regulations finalized in the 
Framework Rule includes an ``attempt to land on, bring into, or 
introduce into, any place subject to the jurisdiction of the United 
States,'' it is clear that the existing statutory and regulatory 
framework prohibit an entity from attempting to land, bring, or 
introduce regulated substances into the United States without expending 
the required allowances, unless the importer meets one of the limited 
exceptions in the regulations. EPA does not intend to narrow prohibited 
behavior as defined under the AIM Act and the associated scope of 
liability with attempts to land, bring, or introduce regulated 
substances into the United States. We are proposing to add language at 
40 CFR 84.5(b) that states: ``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 40 CFR 
84.5(b)(1).'' These proposed changes to 40 CFR 84.5(b) maintain 
liability for attempting to land, bring, or introduce regulated 
substances into the United States without requisite allowances.
    It is possible at the final rulemaking stage for EPA to not amend 
the general prohibition provided in 40 CFR 84.5(b)(1)(i). However, EPA 
identified a need through implementation of the Framework Rule to 
describe to importers which calendar year

[[Page 66385]]

allowance must be expended for a specific import. Since the process of 
importing has multiple different events that play out over a period of 
days, weeks, and months, EPA previously described which year's 
allowances would be needed in case-specific examples as well as through 
the above-cited post on our web page to provide direction as to which 
year's allowances an individual import would be counted against for 
compliance purposes.
    As an alternative proposal, EPA is considering revising text at 40 
CFR 84.5(b)(1)(i) to specify that the calendar year allowances that 
must be expended are based on the time of ship berthing for vessel 
arrivals, border crossing for land arrivals such as trucks, rail, and 
autos, and first point of terminus in U.S. jurisdiction for arrivals 
via air. Such specificity is appropriate given that identifying a 
single point in time facilitates determination of which calendar year 
allowances must be expended.

B. Who must expend allowances for import?

    EPA proposes to specify that only the importer of record can expend 
allowances for an import of regulated substances. Under CBP 
requirements, the importer of record is ultimately responsible for the 
correctness of the entry documentation and all associated duties, 
taxes, and fees.\38\ Specifying that only the importer of record can 
expend allowances for an import would facilitate clarity, transparency, 
and accountability. It can be difficult for EPA to compare import 
records and other filings from CBP against advance notification records 
and the balance sheet of existing allowance holders without a clear 
expectation of how the entity that will expend allowances for an import 
of regulated substances would be identified in CBP filings. This can 
slow down EPA and CBP processing of imports at a minimum,\39\ and in 
the worst-case scenarios can hamper EPA's ability to identify shipments 
to be held at the border to halt potentially illegal shipments from 
entering the United States. Requiring that only the importer of record 
may expend allowances for a shipment would address this difficulty 
because EPA would be able to advise CBP to hold or deny entry of 
merchandise where the importer of record is not an allowance holder or 
had not filed appropriate reports for the destruction, transformation, 
or transhipment of imported merchandise.
---------------------------------------------------------------------------

    \38\ CBP. Tips for New Importers and Exporters. https://www.cbp.gov/trade/basic-import-export/importer-exporter-tips.
    \39\ As a real-world example, during EPA review of HFC imports, 
there was a single import entry with six unique entities (referred 
to as parties), where at least three parties, based on their named 
roles in the entry, could expend allowances to cover the import 
under EPA's existing regulations. This situation can be particularly 
confusing and lead to uncertainty if multiple listed parties in an 
entry are allowance holders.
---------------------------------------------------------------------------

    The Agency is also concerned about instances where allowance 
holders may try to circumvent the requirements in 40 CFR 84.19, 
including but not limited to the requisite offset for inter-company 
transfers of allowances. EPA has received inquiries from entities 
seeking to facilitate imports on an allowance holder's behalf where the 
facilitating entity would be listed on all available CBP paperwork and 
appear in meaningful ways to be the ``importer.'' In such instances, it 
would seem that the facilitating entity is truly importing regulated 
substances, and using a separate entity's allowances to do so. In such 
an instance, it seems more in line with existing EPA regulations and 
the AIM Act that either the allowance holder act more directly in the 
act of importing or for the allowance holder to transfer allowances to 
the facilitating entity. Making the regulatory change proposed in this 
section would help lead to such an outcome and would strengthen EPA's 
ability to track the importation of regulated substances and 
expenditure of allowances and support compliance assurance.
    The Framework Rule at 40 CFR 84.3 defines ``importer'' broadly to 
include the importer of record and any person who imports a regulated 
substance into the United States, the person primarily liable for the 
payment of any duties on the merchandise or an authorized agent acting 
on his or her behalf, the consignee, the actual owner, and the 
transferee, if the right to draw merchandise in a bonded warehouse has 
been transferred. The Framework Rule at 40 CFR 84.5(b)(2) states that 
``[e]ach 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).''
    These two sections of the regulations help EPA maintain the 
integrity of the HFC Allocation Program by imposing broad liability on 
parties involved in importing HFCs while providing regulated parties 
with a flexible approach to contractually allocate risk. Without this 
approach, EPA could be forced to pursue enforcement actions for illegal 
imports against insolvent entities or entities without assets in the 
United States.
    In order to align the proposal to only allow the importer of record 
to expend allowances with the existing regulations, we are also 
proposing to amend 40 CFR 84.5(b)(2) to make it clear that a person who 
meets the definition of an importer will be liable unless they can 
demonstrate that the importer of record possessed and expended the 
appropriate allowances. This would clarify that while the importer of 
record must be the entity possessing and expending allowances for 
imports of bulk regulated substances, if this requirement is not met, 
EPA has discretion to pursue enforcement action and/or administrative 
consequences on all entities that meet the definition of importer for 
violations of those requirements. This approach will encourage all 
parties who meet the definition of importer under EPA's regulations to 
ensure compliance with the HFC Allocation Program, provide regulated 
parties with a flexible approach to contractually allocate risk, and 
facilitate EPA's compliance evaluations.
    Nothing in this proposal is intended To alter the liability 
provision at 40 CFR 84.5(b)(2).

C. Existing Requirement To Expend Allowances for Regulated Substance 
Components of Blends

    In addition to clarifying when an allowance must be expended and 
the entity permitted to expend allowances for import, EPA is proposing 
revisions to 40 CFR part 84.5(b)(1) to reflect and further clarify the 
existing requirement that allowances must be expended to import bulk 
regulated substances regardless of whether the import is of an HFC that 
is imported as a single component substance, i.e., neat substance, or 
whether the HFC is part of a multicomponent substance, i.e., a blend or 
mixture containing one or more regulated substances.
    The requirement to expend allowances equivalent to the EVe of a 
regulated substance that is a component of a blend when the blend is 
imported in bulk is based on a straightforward reading of the statutory 
language and was already made clear in the Framework Rule (86 FR 
55133). EPA stated in the Framework Rule ``allowances [are] necessary 
to produce or import [a] blend, or more precisely, the regulated HFC 
components contained in the blend'' (86 FR 55142). Under the Agency's 
existing approach, the requisite number of allowances to import a 
multicomponent substance in bulk is determined by the exchange

[[Page 66386]]

values of the blend components that are regulated substances. If a 
blend contains multiple regulated substances, then the exchange values 
of each component are used to determine the number of necessary 
allowances (86 FR 55133-55134). If a blend contains components that are 
not regulated substances, then those components are not included in 
determining the number of necessary allowances. While the Framework 
Rule already made this requirement clear, we are proposing to revise 
the regulations so that they more explicitly reflect the already 
existing requirement to expend allowances for import of bulk 
multicomponent substances equivalent to the EVe quantity of regulated 
substance components contained within the blend. This proposed change 
to the regulations would therefore further enhance clarity but would 
not further change the scope of existing requirements.

D. Establish Presumed Amount for Heel Imports of Unknown Quantity

    Many cylinders when ``empty'' still retain a residual amount of its 
contents, and some cylinders contain more than a heel if not all the 
contents are used. Removing this ``heel'' or remaining HFC requires the 
use of recovery equipment, like that used to recover refrigerant from 
an appliance. Through the Framework Rule, EPA has required that any 
import of bulk regulated substances in any quantity, including heels, 
requires the expenditure of allowances (86 FR 55183). In the Framework 
Rule EPA defined a heel as ``the amount of a regulated substance that 
remains in a container after the container is discharged or offloaded 
(that is no more than 10 percent of the volume of the container)'' (40 
CFR 84.3; 86 FR 55183).\40\ During early implementation of the 
requirement that allowances are required for the importation of heels 
of regulated substances, some entities have expressed concern that 
there may be situations where an entity does not know the precise 
weight of the heel imported until the container arrives at the entity's 
U.S. facility. Because the heel is the residual remainder left in a 
container, EPA understands that entities would know the type of 
regulated substance of which the heel is composed, but may not know the 
precise volume or weight of regulated substance remaining. Importers of 
regulated substances must expend allowances corresponding to the 
exchange-value weighted equivalent, which is obtained by multiplying 
the mass of the regulated substance by the exchange value particular to 
that given regulated substance. An entity needs to know the volume or 
weight of the heel to calculate the amount of allowances necessary to 
expend for the import of that heel.
---------------------------------------------------------------------------

    \40\ EPA views this as an amount that is no more than 10 percent 
by weight of the amount of that same substance that is typically 
sold in a ``full'' container of that size. For example, if a 
``full'' cylinder of HFC-134a typically contains 25 pounds of HFC-
134a, then 2.5 pounds or less of HFC-134a remaining in the cylinder 
would be considered a heel.
---------------------------------------------------------------------------

    To address this potential concern, EPA proposes to establish a 
standard presumption of an HFC heel content of 10 percent of the total 
potential volume of that container in EVe terms, if the heel weight has 
not been measured or documented prior to import. This standard 
presumption, by its terms, would only be available for the import of a 
heel, which was previously defined in the Framework Rule as ``the 
amount of a regulated substance that remains in a container after the 
container is discharged or offloaded (that is no more than 10 percent 
of the volume of the container)'' (40 CFR 84.3; 86 FR 55183). Because 
10 percent is the upper bound of the volume of the container that a 
regulated substance could comprise and still be considered to be a 
``heel,'' and the standard presumption, if finalized, would only be 
available for a shipment that meets the regulatory definition of a 
``heel.'' EPA is proposing the standard presumption at the 10 percent 
level as an inherently conservative estimate of what quantity would be 
a heel in a container. If an entity wanted to take advantage of this 
standard presumption, under the proposed approach that entity would be 
required to expend allowances equivalent to 10 percent of the volume of 
the container being comprised of the regulated substance that is 
residual in the container. Under this proposed approach, the entity 
would also utilize the 10 percent presumption for the advance 
notification requirement of 40 CFR 84.31(c)(7). The proposed standard 
presumption is intended to only apply in situations where an entity is 
importing a heel of a regulated substance (i.e., the container contains 
10 percent or less of the total potential volume of the container) and 
the entity does not know the precise quantity, volume, or weight of the 
heel. If the quantity of HFCs in the container is known (or the 
importer should have had reason to know), then the regulations would 
apply as for any other shipment, i.e., allowances would need to be 
expended to cover the quantity of HFCs held in the container. Given the 
possibility that an importer could use this provision as a way to 
underreport how much HFC they are importing, EPA requests comment on 
whether to set limits for the number of times an importer could use 
this presumption or whether to limit the total quantity that could be 
eligible in a given shipment, and if so, what the appropriate limits 
should be. For example, EPA could limit the use of the presumption to a 
set number of containers in a given year, to a set size category of 
containers (e.g., for containers that have a maximum capacity under 7 
kg), to shipments with a set number of containers (e.g., fewer than 20 
containers in a shipment), and/or if the net weight of regulated 
substances in a shipment is below a set weight (e.g., 200 kg). 
Alternatively, EPA could presume the container is full unless the 
importer demonstrates otherwise, such as with records documenting the 
actual weight. EPA also requests comment on whether a provision like 
this is needed or if importers have resolved the early concerns with 
determining the heel weight prior to import.
    As an alternative, EPA is also considering an option of allowing 
the importer of record to submit a provisional estimate of the quantity 
of heel imported, but requiring within a two-week period that the 
provisional estimate be corrected to match the exact amount of the 
imported HFC heel content. EPA invites comment on how this alternative 
option would align with the proposal in section V.A of this preamble. 
In particular, EPA is unsure how and when allowances would be expended 
under this provisional estimate model, and if allowances are expended 
based on the provisional estimate, how expended allowances would be 
reconciled with the corrected exact amount of imported heel. EPA is 
also concerned what the enforcement implications of this approach would 
be and seeks comment on whether such an approach would create avenues 
for an entity to illegally import that are not currently present under 
EPA's existing regulations.
    EPA notes that these proposals would only apply to imports of HFCs 
that are heels and would not change the requirement to know the precise 
quantity of HFCs in a heel for an export. Further, anyone requesting an 
additional consumption allowance under 40 CFR 84.17 and anyone 
exporting HFC heels must continue to report the actual weight of a heel 
that is exported.

[[Page 66387]]

VI. How is EPA proposing to clarify and revise recordkeeping and 
reporting requirements?

    EPA established recordkeeping and reporting requirements in the 
Framework Rule, in accordance with subsection (d) of the AIM Act. These 
requirements can be found in 40 CFR 84.31. EPA is proposing to make 
amendments to certain recordkeeping and reporting requirements as well 
as proposing new recordkeeping and reporting requirements based on the 
experience gained in implementing the HFC phasedown program.

A. How is EPA proposing to modify the import reporting requirements?

    In the Framework Rule, EPA established reporting requirements for 
importers at 40 CFR 84.31(c). EPA is proposing amendments which include 
specifying reporting obligations that fall to the importer of record, 
modifying elements of the advance notification requirement, clarifying 
how to consider import of heels, and new application of joint and 
several liability to quarterly and advance notification reporting 
requirements. EPA proposes all these amendments to provide additional 
detail on requirements and further promote transparency and consistency 
in implementation and enforcement of the rule.
1. Specify Reporting Obligations on the Importer of Record
    To align with the proposal made elsewhere in this notice that only 
the importer of record may expend allowances for the import of bulk 
regulated substances, EPA is proposing to specify that certain 
reporting obligations will fall to the importer of record. 
Specifically, EPA is proposing that the importer of record, or their 
authorized agent,\41\ would be required to file the advance 
notification report pursuant to 40 CFR 84.31(c)(7), and the importer of 
record will be required to make quarterly reports pursuant to 40 CFR 
84.31(c)(1). EPA is making this proposal to improve clarity of who must 
fulfill certain reporting requirements with the Agency and also ease 
EPA implementation in aligning the reporting requirement with the 
entity obligated to expend allowances for the import.
---------------------------------------------------------------------------

    \41\ For purposes of providing advance notification of import 
through a system such as the ABI, the vast majority (if not all) 
notifications for the imports of regulated HFCs have been filed by 
customs brokers who are licensed and regulated by CBP to assist 
importers and exporters in meeting Federal requirements governing 
imports and exports. EPA included ``authorized agents'' as 
permissible reporting entities to accommodate this standard business 
practice.
---------------------------------------------------------------------------

2. Modify Advance Notification of Import Requirements
    EPA's regulations contained in 40 CFR 84.31(c)(7) require ``[a] 
person importing a regulated substance, or their agent,'' to report 
certain information ``no later than 14 days before importation.'' The 
Agency requires reporting of data elements that are generally already 
collected by CBP (e.g., cargo description, port of entry). This 
approach simplifies the process for importers or their customs brokers 
to provide such information to EPA on time. This would generally be at 
least, and likely more than, 14 days before a vessel carrying HFCs 
berths. EPA finalized these requirements because timely access to this 
information helps the Agency ensure that annual production and 
consumption in the United States are consistent with the reductions 
established by Congress in the AIM Act. Under the AIM Act, some 
entities will face burdens and costs associated with the 
Congressionally mandated phasedown; those increased burdens and costs 
create economic incentives to avoid compliance. That reality increases 
EPA's statutory and policy imperative to identify and apply tools that 
counter those incentives to increase the rate of compliance. Given the 
risk of noncompliance, as described throughout section IX of the 
Framework Rule, there is an imperative to develop reasonable tools to 
ensure compliance and thus achieve the objectives of the AIM Act. EPA 
has required entities to provide advance notification through ACE so 
that EPA can conduct a real-time review of allowances before the 
imported material is at a U.S. port or border. Given the serious 
concerns about potential noncompliance and the undermining of 
Congress's directive to ensure reductions in production and consumption 
occur consistent with the statutory schedule, real-time review of 
import data will support EPA's ability to effectively implement the 
statute.
    The regulation enumerates several required elements that must be 
included in an advance notification of import filed through the CBP-
authorized electronic data interchange system, such as the ABI. To 
align with the proposal made elsewhere in this notice that only the 
importer of record may expend allowances for the import of bulk 
regulated substances, EPA is proposing to specify that the advance 
notification reporting obligation falls to the importer of record, or 
their authorized agent. If EPA finalizes this proposal, this should 
improve clarity of who must submit the advance notification reports and 
also ease EPA implementation in aligning the reporting requirement with 
the entity obligated to expend allowances for the import.
    To support effective real-time review of regulated HFC imports, 
including but not limited to using reported data to track imports using 
CBP databases to determine when allowances must be expended, EPA is 
proposing to add a required element to the report required pursuant to 
40 CFR 84.31(c)(7), specifically the container number(s) of the 
shipment (if applicable), for all modes of import. EPA is also 
proposing that for maritime shipments, the vessel name and the 
International Maritime Organization (IMO) number must be included as 
part of the pre-importation notification.
    EPA's current regulations in 40 CFR 84.31(c)(7) require provision 
of the ``quantity'' (in kilograms) of each import in the advance 
notification of import. Some regulated entities have expressed 
confusion over how to interpret this term. Under the current 
``quantity'' requirement, some appear to be providing the net weight, 
while others appear to be providing the gross weight. EPA is seeking to 
resolve this ambiguity and standardize reporting. To improve clarity in 
the Agency regulations and provide for consistent treatment across 
regulated entities, EPA is proposing to specifically require the 
provision of both the net weight (or net product weight) and gross 
weight (net weight plus container weight), as well as unit of mass 
(i.e., kilogram), for each container in the shipment in the pre-import 
notification. EPA requests comment on any potential difficulties that 
would be associated with meeting this revised requirement.
    Currently 40 CFR 84.31(c)(7) requires the submission of advance 
notification ``no later than 14 days before importation'' of any 
regulated substance. Footnote 97 of the preamble to the Framework Rule 
states, in part: ``EPA is using the term `date of importation' 
consistent with CBP's definition at 19 CFR 101.1. ``Date of 
importation'' means ``in the case of merchandise imported otherwise 
than by vessel, the date on which the merchandise arrives within the 
Customs territory of the United States. In the case of merchandise 
imported by vessel, ``date of importation'' means the date on which the 
vessel arrives within the limits of a port in the United States with 
intent then and there to unlade \42\ such

[[Page 66388]]

merchandise.'' To ensure consistency EPA proposes to amend 40 CFR 
84.31(c)(7) to clarify that our reference to ``before importation'' in 
the Framework Rule means ``before the date of importation (consistent 
with the definition at 19 CFR 101.1).'' EPA also proposes to clarify in 
40 CFR 84.25(a)(1)(v) and 40 CFR 84.31(c)(3)(i)(D) that these 
references are consistent with the definition at 19 CFR 101.1.\43\ The 
``Import Date'' box on CBP Form 7501, ``Entry Summary,'' as well as CBP 
Form 214 for entries where importers are applying for foreign-trade 
zone admission and/or status designation may provide information about 
the date of importation, but it is the importer's obligation to ensure 
that it has submitted its advance notification report in a timely 
manner regardless of the date identified in the Import Date box on 
these forms.
---------------------------------------------------------------------------

    \42\ In the context of imports, EPA considers ``unlade'' to mean 
unload.
    \43\ These clarifications citing, and relying on, definitions 
from CBP are intended to provide a consistent point in time for 
which importers must submit advance notification; however, they are 
not meant to change or otherwise be linked to how EPA has defined 
``import'' in 40 CFR part 84.
---------------------------------------------------------------------------

    As noted above in this subsection, EPA currently requires prior 
notification no later than 14 days in advance. Based on EPA's 
implementation experience, this timeframe is achievable for shipment by 
sea, but can be impractical based on standard practices used for non-
marine vessel imports, such as from trucks, trains, and airplanes. 
Importers bringing in goods via these transportation modes may not have 
the necessary information available at least 14 days in advance under 
current standard market practice. However, prior notification is 
important for EPA and CBP to be able to adequately review the shipment 
and relevant information. Accordingly, EPA is proposing to distinguish 
between modes of transport and to shorten the prior notification 
requirement for truck, rail, air, and other non-sea arrivals to 5 days 
prior to the date of importation, as discussed in the prior paragraph. 
EPA is proposing a 5-day prior notification after consultation with CBP 
about similar notification provisions used by other federal government 
agencies and informed by our stakeholder meetings that included customs 
brokers that have experience with importing a range of goods. EPA is 
requesting comment on whether this revised, 5-day prior notification is 
achievable for imports arriving via air, rail, truck, and other non-sea 
modes of transport. EPA is also considering whether it would be 
warranted to shorten the prior notification for arrivals by sea and is 
requesting comment on whether a 10-day prior notification requirement 
would be appropriate for arrivals by sea, since EPA has heard from some 
regulated entities that it takes fewer than 14 days for certain marine 
shipments from Europe.
3. Clarify the Reporting of Heels
    In the previous ODS phaseout, EPA witnessed some situations where 
imported ODS, including in heels, had been reported to CBP as U.S. 
goods returned as a way to evade EPA's import restrictions. The Agency 
is concerned this could happen for HFCs. Given that EPA requires 
expenditure of allowances for import of any bulk regulated substance 
and must monitor the import of such HFCs, including for heels, as 
discussed in section V.D of this preamble, we are clarifying that the 
HTS Code for the regulated substance, regardless of whether or not 
comprising the heel, must be used, and not the HTS codes for U.S. goods 
returned or empty containers. As stated in the Framework Rule, EPA is 
concerned that misreported imports of HFCs could provide avenues for 
illegal imports or could contribute to inefficient implementation and 
processing of EPA and CBP procedures for comparing shipments against 
available allowances (86 FR 55183). Reporting all volumes of regulated 
substances with the applicable HTS Code for the contained HFCs 
facilitates accurate treatment of the imports of these regulated 
substances under EPA regulations.
4. Changes to and Requirement of Importer of Record Information
    As part of the Agency's overall efforts to better identify and 
assess potentially violative shipments of regulated substances and to 
simultaneously streamline the import review process, EPA proposes to 
require the submission of certain information directly to EPA that had 
been voluntarily provided, in part, through the importer of record form 
(EPA Form #5900-556). EPA is proposing a regulatory requirement that 
certain information must be submitted by any entity anticipating being 
the importer of record for a shipment of regulated substances by 
November 15 of the prior calendar year. In other words, an entity that 
anticipates being the importer of record for a shipment of HFCs during 
calendar year 2024 must submit the required information by November 15, 
2023. If an entity is not issued allowances directly from EPA, is the 
recipient of transferred or conferred allowances and it is 
impracticable for the entity to submit the importer of record form by 
November 15, EPA is proposing that the importer of record form be 
submitted within 15 calendar days of receiving the Agency's non-
objection notice for conferral or inter-company transfer.
    EPA is also proposing that if changes are necessary on the importer 
of record form after its initial submission that those changes be made 
at least 21 calendar days prior to any import of bulk regulated 
substances for which the concerned entity will be the importer of 
record after the change in information occurs.
    As explained in the Framework Rule and reiterated in section VIII.C 
of this preamble, movement of allowances between a parent company and 
its subsidiaries, or among companies that are commonly owned, may occur 
without a transfer (86 FR 55145). However, there may be instances where 
these corporate relationships are not immediately clear to EPA. The 
importer of record form provides information on corporate relationships 
to EPA, and accounting for such instances would ensure not only that 
allowances are being expended by the right entity, but also that 
reviews of shipments are not unnecessarily delayed. In a similar 
manner, entities receiving allowances may operate under different 
names, e.g., ``Doing Business As'' (DBA), where it is not immediately 
clear to the Agency that the DBA is associated with the allowance 
holder. Accordingly, EPA is proposing that the names of all 
subsidiaries, entities majority owned and/or controlled by the same 
individual(s),\44\ all DBAs, and any corresponding importer of record 
numbers are included on the importer of record form, even if the 
importer of record number(s) is identical for the subsidiaries, 
entities majority owned and/or controlled by the same individual(s), 
and/or DBAs as it is for the allowance holder. In order to further 
efficient and accurate review of imports by EPA, the Agency reminds 
regulated entities of the importance of ensuring that when an allowance 
holder or associated subsidiary, entity that is majority owned and/or 
controlled by the same individual(s), and/or DBA provides advance 
notification of import filed through a CBP-authorized electronic data 
interchange system, such as the ABI, that the importer of record number 
accurately aligns with the name of the importer.
---------------------------------------------------------------------------

    \44\ Note that EPA intends to align the specific definition of 
``entities majority owned and/or controlled by the same 
individual(s)'' with the proposal regarding the ability to move 
allowances among commonly owned or companies with certain 
affiliation without a transfer, if it finalizes the proposal in 
section VIII.C of this preamble.
---------------------------------------------------------------------------

    As part of this information submission, EPA is also proposing that

[[Page 66389]]

if an entity receiving allowances (either allocated directly by EPA or 
through a conferral or transfer) includes subsidiaries, entities 
majority owned and/or controlled by the same individual(s), and/or DBAs 
as part of its form, the corporate structure of the entity receiving 
allowances must also be provided, and the description of the corporate 
structure must, at a minimum, explicitly show the relationship between 
the allowance holder and each subsidiary, entity that is majority owned 
and/or controlled by the same individual(s), and/or DBA. An entity also 
would need to provide the owners, and their respective percentage of 
ownership, of each subsidiary, entity that is majority owned and/or 
controlled by the same individual(s), and DBA on the submitted form. 
Further, an entity would need to indicate how many allowances will be 
expended by each other affiliated entity (e.g., subsidiaries, majority 
owned and/or controlled), specifically a quantity of allowance that 
will be expended by each affiliated entity identified by name and 
importer of record number(s). Collectively, the proposed revisions to 
the importer of record form would allow EPA to have a current 
understanding of pertinent information concerning the allowance holder, 
such as how to confirm that the importer(s) of record was still active, 
whether there had been a change in ownership, and whether ownership of 
subsidiaries and other majority-owned and/or controlled entities was 
shared, common, or familial. These revisions would help ensure that EPA 
has the updated information necessary to efficiently monitor and 
implement this program.
    As an alternative to EPA's proposal to require the reporting of how 
many allowances will be expended by each other affiliated entity, EPA 
is considering and seeking comment on requiring information as part of 
the advance notification requirement of 84.31(c)(7) that would specify 
which entity was allocated the allowances or received the allowances 
through a transfer that are associated with an individual shipment.
5. Joint and Several Liability for Importer Reporting Requirements
    EPA proposes in section VI.A.1 of this preamble to specify that the 
advance notification reporting obligation of 40 CFR 84.31(c)(7) and 
quarterly reporting requirements of 40 CFR 84.31(c)(1) falls to the 
importer of record, or their authorized agent for advance notification. 
EPA is making this proposal to align with the proposed change that the 
importer of record must expend allowances to import bulk regulated 
substances. However, such proposed changes to the reporting 
requirements could have an adverse impact on compliance with and/or 
EPA's ability to enforce reporting obligations. As explained in more 
detail elsewhere in this notice and in EPA's September 2021 Framework 
Rule, compliance with reporting requirement is critically important so 
that EPA can build a robust and enforceable allowance system. Complete 
and accurate reporting is an important component of EPA's efforts to 
monitor compliance, verify relevant information, and enforce 
requirements.
    Accordingly, EPA proposes to apply joint and several liability for 
violations of the quarterly reporting and the advance notification 
reporting requirements. Specifically, in 40 CFR 84.31(c)(10), EPA 
proposes that each person meeting the definition of an importer is 
jointly and severally liable for a violation of the quarterly reporting 
requirements at 40 CFR 84.31(c)(1) unless they can demonstrate that the 
importer of record fulfilled the quarterly reporting requirements, and 
in 40 CFR 84.31(c)(11), EPA proposes that each person meeting the 
definition of an importer is jointly and severally liable for a 
violation of the advance notification requirements at 40 CFR 
84.31(c)(7) unless they can demonstrate that the importer of record or 
their authorized agent fulfilled the advance notification requirements. 
These revisions would provide EPA with additional enforcement tools to 
ensure that EPA receives necessary information concerning past and 
incoming imports.
    Adding joint and several liability would parallel the proposal made 
in section V.B of this preamble to apply the joint and several 
liability provisions of 40 CFR 84.5(b)(2) to each person who meets the 
definition of an importer, unless they can demonstrate that the 
importer of record possessed and expended the appropriate allowances 
for the import of bulk regulated substances. As further discussed in 
section V.B of this preamble, this joint and several liability 
provision provides EPA discretion to pursue enforcement actions 
necessary to ensure compliance while providing regulated parties with a 
flexible approach to contractually allocate risk.
    With respect to the proposal to extend joint and several liability 
to reporting provisions, EPA requests comment on any potential 
reporting difficulties that could be associated with extending joint 
and several liability for these importer reporting requirements and on 
the potential burden or downsides associated with these proposed 
requirements. This proposed change would require individuals involved 
in the import of HFCs to coordinate to ensure reporting is complete and 
accurate, so EPA also seeks comment on whether additional resources 
and/or processes would be helpful to support this coordination and 
prevent duplicative reporting for the same import.
    Note that the importer of a regulated substance in 40 CFR 
84.31(c)(2) must maintain certain records to document each import. EPA 
also seeks comment on whether more specificity is needed than 
``importer,'' for example to define that recordkeeping obligations 
would fall specifically on the importer of record, and is taking 
comment on the effectiveness, accuracy, and completeness of the 
importer bearing responsibility for the recordkeeping in this section.

B. Modify Recordkeeping and Reporting Requirements Regarding Expending 
Allowances

    In the Framework Rule, EPA codified various recordkeeping 
requirements for producers and importers of HFCs. In 40 CFR 
84.31(c)(2), EPA established the types of records that importers must 
maintain. In 40 CFR 84.31(b)(3), EPA codified recordkeeping obligations 
for producers. For both importers and producers, EPA is proposing to 
add an obligation to the existing recordkeeping requirements that 
producers and importers undertake same day documentation of any 
allowances expended. Put another way, if a producer or importer expends 
allowances, on the same day the producer or importer would have a 
recordkeeping obligation to document the date, quantity, and type of 
allowances expended on that date. EPA is further proposing to require 
that entities include this record of same day documentation as part of 
the quarterly report required under 40 CFR 84.31(b)(2) (for producers) 
and 40 CFR 84.31(c)(1) (for importers). Additionally, EPA is proposing 
to require each producer and importer certify to EPA as part of their 
quarterly reporting that they expended the requisite number of 
allowances on the dates specified in the form for each date-specific 
production or import transaction.
    If this proposal is finalized, EPA would add additional fields to 
the producer and importer reporting forms to document the specific date 
allowances were expended. This would be a slight change for the 
importer form, since it already includes a ``date of import'' column, 
which should match

[[Page 66390]]

the ``date allowances were expended'' on a per transaction basis. For 
the quarterly producer report, EPA would need to collect date-specific 
production information.
    Finalizing these additional recordkeeping and reporting obligations 
would be intended to allow for better accountability to ensure no 
entity is producing ``regulated substances, intentionally or 
unintentionally, in excess of the quantity of unexpended production 
allowances and consumption allowances or unexpended application-
specific allowances held'' by that entity at a given point in time (40 
CFR 84.5(a)(1)). Finalizing these recordkeeping and reporting 
obligations would also allow EPA better accountability to ensure that 
entities expend allowances on import per the requirements of 40 CFR 
84.5(b)(1)(i). EPA is proposing this additional requirement to 
strengthen and ease implementation and enforcement of the HFC phasedown 
obligations. In requiring such a recordkeeping obligation, EPA will 
enable better oversight for any onsite inspections to align regulated 
substances found on site and corporate records with up-to-date 
information on allowances expended for such materials. In requiring 
these records and a certification be included in the entity's quarterly 
report, EPA intends to enable better coordination of information 
provided by the Agency with Customs records and other available 
information to help ensure the integrity of the allowance system. EPA 
understands that entities likely already undertake this sort of date-
specific tracking of allowances for corporate records, so expects that 
establishing this requirement would have minimal effect on regulated 
entities, but invites comment on the potential burden or downsides 
associated with this proposed requirement.

C. Modify the Reporting of Regulated Substances Produced for 
Transformation, Destruction or Use as a Process Agent at a Different 
Facility Under the Same Owner

    EPA currently requires in 40 CFR 84.31(b)(2)(i)-(iii) that each 
producer of a regulated substance include in the quarterly report for 
each facility information on the quantity of each regulated substance 
produced for use by the producer or a second party in processes 
resulting in their transformation, destruction, or use as a process 
agent. There are situations, however, where regulated substances are 
produced at one facility, but transformed, destroyed, or used as a 
process agent at another facility owned by the same entity. Such 
situations are distinct from regulated substances transformed, 
destroyed, or used at the same facility where the regulated substances 
were produced and those transformed, destroyed, or used by an entity 
different from the one that produced the regulated substances. EPA is 
proposing that 40 CFR 84.31(b)(2)(i)-(iii) be modified to include 
requirements to report the name, quantity, and recipient facility for 
regulated substances produced at one facility for, correspondingly, 
transformation, destruction, or use as a process agent at another 
facility owned by the same entity.
    Since EPA requires the names and quantities of transformed or 
destroyed regulated substances produced or imported by another entity 
to be reported at the facility level under 40 CFR 84.31(e)(1), these 
proposed revisions to these sections would establish consistency within 
the regulations under 40 CFR part 84. Furthermore, these revisions 
would provide greater transparency within the system and would better 
align with current AIM Act reporting forms and the GHGRP, both of which 
track transformation, destruction, and use as a process agent by 
facility. This facility-level reporting would increase transparency, 
such as for environmental justice concerns so that local communities 
have better insight into how regulated substances may move between 
facilities owned by a single entity. Such information would also 
provide EPA a better understanding of industry practice, help verify 
disposition of regulated substances, and may inform future rulemakings.

D. Additional HFC Production Facility Emissions Reporting Requirements

    Currently, EPA requires, as part of the producer one-time report, 
that producers provide a ``list of any coproducts, byproducts, or 
emissions from the production line that are other regulated substances; 
ozone-depleting substances listed in 40 CFR part 82, subpart A; or 
hazardous air pollutants [HAP] initially identified in section 112 of 
the CAA, and as revised through rulemaking and codified in 40 CFR part 
63'' (40 CFR 84.31(b)(1)(v)). These one-time reports were due May 1, 
2022, for existing facilities and within 120 days for any facility that 
begins producing HFCs after January 1, 2022.
    The reported information is qualitative (i.e., producers must only 
provide a list of the relevant chemicals) and is only required a single 
time, so the existing regulatory requirement would not allow the Agency 
to monitor changes in the list of relevant chemicals or volumes of 
relevant chemicals at facilities. EPA is particularly concerned about 
an inability to monitor such changes at facilities as the HFC phasedown 
progresses and as facilities may transition to production of lower EVe 
regulated substances or away from production of regulated substances 
altogether. Some entities with multiple production facilities may 
choose to consolidate production of regulated substances at a subset of 
facilities as the phasedown continues, which could lead to an increase 
in regulated substance production at a single facility, despite the 
overall phasedown of production. EPA stated its intention in the 
Framework Rule to ``continue to monitor the impacts of [the HFC 
phasedown] program on HFC and substitute production, and emissions in 
neighboring communities, as we move forward to implement this rule'' 
(86 FR 55129).
    As such, EPA is proposing to build on the one-time reporting 
requirement and require annual reporting of the emissions from each 
facility's HFC production line emissions units, specifically HAP, ODS, 
and HFCs.\45\ Collecting these data would allow the Agency to more 
closely monitor potential impacts of the HFC phasedown on relevant 
emissions and on communities located near facilities producing 
regulated substances. As noted in the Framework Rule, ``EPA may 
consider taking appropriate action in the future[,] including action [. 
. .] under CAA authorities, in future HFC allocation rules, or under 
other relevant authorities, if we develop further information 
indicating there is a risk of disproportionate impacts'' (86 FR 55129). 
EPA views information on the impacts of HFC production as important for 
informing policies, regulations, and other decisions, including to 
carry out the Agency's commitment to environmental justice. For 
example, EPA could use data collected through this reporting 
requirement, if finalized, in crafting the next allowance allocation 
methodology if shifts in production resulted in disproportionate 
impacts on overburdened communities. EPA could also consider using the 
reported data to propose alternative offsets for production allowance 
transfers based on potential disproportionate impacts. These proposed 
regulatory requirements

[[Page 66391]]

can also be viewed as part of an effort to improve data transparency 
particularly with regard to the Agency's commitment to the fair 
treatment and meaningful involvement of all people regardless of race, 
color, national origin, or income, with respect to the development, 
implementation, and enforcement of environmental laws, regulations, and 
policies. Therefore, EPA is proposing to require more detailed annual 
reporting on emissions from each facility's HFC production lines.
---------------------------------------------------------------------------

    \45\ While most ODS and HFCs are not HAP and generally do not 
have local effects, some do (e.g., carbon tetrachloride). Further, 
collecting this information from HFC production facilities allows 
EPA to better track potential changes in emissions of all three sets 
of chemicals and inform policies, regulations, and other decisions.
---------------------------------------------------------------------------

    The Agency has reviewed other potential sources of data to 
determine if facilities producing regulated substances are already 
required to report annual emissions at the production line level under 
other EPA regulatory programs, but did not identify such requirements. 
Based on EPA's review, data currently required to be submitted to EPA 
under different authorities are not detailed or comprehensive enough to 
allow the Agency to sufficiently monitor potential changes in emissions 
due to the phasedown of HFCs. Emissions data reporting is required for 
some larger facilities, and can be obtained, at the facility- or 
process-level, through the National Emissions Inventory (NEI), Toxics 
Release Inventory (TRI), and Title V permits. However, process-level 
emissions data are not required for all HFC production facilities, 
which results in data gaps that hinder EPA's ability to identify 
relevant emissions and track changes over time.
    AirToxScreen, and prior to its 2017 release the National Air Toxics 
Assessment (NATA) risk screen, identifies the cumulative risk to 
individuals within an area due to impacts from surrounding facilities 
without distinguishing between emission sources. While community-level 
analyses are available for all facilities producing regulated 
substances based on cumulative emissions, an HFC production facility 
may be emitting only one portion of the total modeled emissions with 
other portions being attributable to other nearby facilities 
contributing to the overall risk value. The currently available data do 
not allow EPA to consistently isolate the portion of the risk 
associated with HFC production, or to track potential changes in the 
overall risk level that could be attributable to the phasedown in HFC 
production and consumption, for example resulting from shifts in 
production levels of HFCs.
    To address these identified data and knowledge gaps, EPA is 
proposing to require that each facility producing regulated substances 
report on an annual basis emissions for each HFC production line, 
including the:

--Quantity (in pounds) of each of the following emitted at the facility 
in the prior year: HAP initially identified in section 112 of the CAA, 
and as revised through rulemaking and codified in 40 CFR part 63; HFC 
listed in Appendix A to 40 CFR part 84; and ODS listed in appendix F of 
40 CFR part 82, subpart A; and
--Quantity (in pounds) of each such HAP, HFC, or ODS emitted in the 
prior year on an emission unit basis (e.g., ``Storage tank #45a'', or 
``Scrubber #2'').

    EPA proposes that the reported emission levels reflect each 
facility's and emission unit's actual operating hours, production 
rates, in-place control equipment, and types of materials processed, 
stored, or combusted during the preceding calendar year. EPA is 
considering a range of options by which emissions would be reported and 
is welcoming comment on the associated data, calculations, and method 
used to determine emissions. While EPA is currently considering a range 
of options, the Agency intends to finalize a single chosen approach for 
determination of emissions in that there is a limited, well-understood 
universe of HFC production facilities and those facilities share a 
number of common features.

    EPA is considering the following options to be applied to determine 
the emissions required to be reported under this proposed approach:

--Continuous emission monitoring system;
--tack test at a six month or annual frequency;
--Material balance;
--U.S. EPA emission factor; or
--The compliance method required under the most recent permit issued to 
the facility pursuant to 40 CFR part 70 or 71, under the facility's 
operating permit for sources without a permit under 40 CFR part 70 or 
71, or using federally recognized procedures if emissions cannot be 
determined using the compliance methods from the facility's air permit.

    EPA is also seeking comment on whether fenceline monitoring, in 
particular of HAP that potentially pose the greatest risk to local 
communities, would be appropriate, in combination with or as an 
alternative to gathering data on emissions from these facilities. If 
this approach is finalized instead, EPA seeks comment on the advantages 
and disadvantages of this approach, what metrics should be reported, 
and how EPA could use this data to better understand the role that HFC 
production plays in emissions of HAP, HFCs, and ODS. EPA is proposing a 
range of options and is seeking comment to inform what option to 
finalize in order to allow for the effective monitoring of these 
emissions and gathering of information that could be relevant if a 
future rule would be appropriate under the AIM Act, CAA or other 
authority to address any potential disproportionate impacts associated 
with the HFC phasedown. EPA also requests comment on what methods of 
emissions estimation and monitoring are in practice currently, and 
whether these methods are appropriate for monitoring emissions changes 
over time at regulated substance production facilities. The Agency is 
also taking comment on whether the data listed in this proposal for 
additional reporting are already required under different authorities. 
Finally, in the interest of data transparency, if finalized, EPA 
intends to publish the emissions data on the Agency's website. The 
public availability of the data will allow for the public, local 
environmental agencies, or other entities to also monitor emissions 
changes due to changes in HFC production from facilities in their 
communities.
    Subsection (k) of the AIM Act provides that section 114 of the CAA 
applies to ``any rule, rulemaking, or regulation'' promulgated pursuant 
to the AIM Act. For purposes of applying section 114, the AIM Act 
provides that section 114 of the CAA shall apply as though the AIM Act 
were part of Title VI of the CAA. Section 114(a) provides EPA with the 
authority, among other things, to require any person who owns or 
operates any emission source that may have information necessary to 
provide such information as the Administrator may reasonably require 
for purposes of carrying out any provision of the CAA, or the AIM Act 
pursuant to subsection (k). As noted, EPA has determined that requiring 
reporting of the outlined data regarding emissions from HFC production 
facilities is necessary to inform future decisions on whether it may be 
appropriate to undertake a rulemaking to address potential 
disproportionate impacts associated with the HFC phasedown.
    The Agency requests comment on whether it would be appropriate and 
feasible to require each facility producing an HFC to report on an 
annual basis the quantity of each criteria air pollutant, and its 
precursors, for which EPA has established a National Ambient Air 
Quality Standard

[[Page 66392]]

(NAAQS) \46\ emitted by the facility and the quantity of each such 
pollutant emitted annually from each HFC production line on an emission 
unit basis. EPA is proposing to require reporting both for the 
regulated substance production line as a whole and the emission units 
associated with the production line to understand where emissions are 
most significant and to better gauge what, if any, additional 
regulatory action could be considered in future.
---------------------------------------------------------------------------

    \46\ The pollutants for which EPA has established a NAAQS are: 
sulfur dioxide, PM10, PM2.5, carbon monoxide, 
ozone, nitrogen dioxide, and lead. See 40 CFR part 50.
---------------------------------------------------------------------------

VII. How is EPA proposing to revise sampling and testing requirements?

    In the Framework Rule codified at 40 CFR 84.5(i), EPA established 
the requirement to label containers containing a regulated substance 
that are sold or distributed, or offered for sale or distribution, and 
for certain entities to confirm the accuracy of the labels by testing a 
representative sample of contents to verify that the composition 
matches the container label. In that regulatory section, EPA also 
codified a prohibition on the sale or distribution of regulated 
substances for use as a refrigerant that did not meet specifications in 
appendix A to 40 CFR part 82. EPA is proposing to amend these 
requirements and related requirements to establish additional 
verification requirements and codify procedures to be followed to meet 
the requirement to test a representative sample. These proposed changes 
are intended to provide clarity and direction to regulated entities, 
create a consistent approach to help ensure smoother implementation, 
and provide greater assurance on the accuracy of these container 
labels, particularly for non-refrigerant applications. If finalized, 
these proposed revisions are intended to lead to improved veracity in 
compositional testing, which in turn would result in more accurate 
expenditures of consumption and production allowances. These 
modifications would also improve the ability of EPA to understand the 
process taken and reliability of information gleaned in the 
compositional determinations that are made throughout the supply chain.
    Specifically, EPA is proposing to (1) Modify 40 CFR 84.5(i)(3)(i) 
to add that already required sampling and testing of regulated 
substances must follow a combination of appendix A of 40 CFR part 82, 
subpart F and EPA Method 18 in Appendix A-6 to 40 CFR part 60 to verify 
the label composition for all applications; (2) add a requirement to 
sample and test under specified methodology to ensure compliance with 
the existing requirements in 40 CFR 84.5(i)(3)(ii); (3) define the 
records required under 40 CFR 84.33 associated with testing and add 
recordkeeping requirements to 40 CFR 84.33 for recyclers for fire 
suppression and repackagers to ensure results from required testing are 
maintained; (4) add definitions at 40 CFR 84.3 of ``batch'' and 
``representative sample'' and clarify the relationship between these 
terms; (5) add a definition at 40 CFR 84.3 for ``laboratory testing'' 
such that laboratories used by regulated entities to meet the existing 
requirement in 40 CFR 84.5(i) must be accredited and follow the test 
methods in appendix A of 40 CFR part 82, subpart F; and (6) add a 
requirement that certificates of analysis accompany all imports of 
regulated substances.

A. Use of Appendix A to 40 CFR Part 82 and EPA Method 18 in Appendix A-
6 to 40 CFR Part 60 for Sampling and Testing

    In the Framework Rule EPA codified regulations in 40 CFR part 84 
that require, for regulated substances sold as refrigerants, that 
sampling must be done consistent with appendix A to 40 CFR part 82, 
subpart F. Appendix A is based on the Air-Conditioning, Heating, and 
Refrigeration Institute (AHRI) Standard 700-2016, Specifications for 
Refrigerants. Appendix A references detailed ``referee tests'' that are 
included in the 2008 Appendix C to AHRI Standard 700-2014, which are 
incorporated by reference in 40 CFR 82.168(b)(2). Generic maximum 
contaminant levels are defined in 40 CFR 82 subpart F appendix A1.
    40 CFR part 84 does not specify the sampling methods that must be 
used to verify that the composition of the regulated substances matches 
the container labeling for regulated substances that are sold for 
another use than as refrigerants. The current regulations also only 
explicitly require that sampling is consistent with appendix A, but 
they do not explicitly require that test methods are consistent with 
appendix A.
    EPA is proposing to revise 40 CFR 84.5(i)(3)(i), such that no 
person producing, importing, reclaiming, recycling for fire 
suppression, or repackaging regulated substances may sell or 
distribute, or offer for sale or distribution, regulated substances 
without first testing a representative sample of the regulated 
substances that they are producing, importing, 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 40 CFR part 82, subpart 
F appendix A for regulated substances offered for sale and distribution 
as refrigerants and using the following testing methods for regulated 
substances offered for non-refrigerant uses: \47\
---------------------------------------------------------------------------

    \47\ EPA is proposing to use Part 7 of 2008 Appendix C for 
Analytical Procedures for AHRI Standard 700-2014 as the testing 
method for HFC-134 is because HFC-134a is covered as a potential 
contaminant, whereas Part 9 looks at HFC-134 as a contaminant in 
HFC-134a. The same rationale applies to the testing methods used for 
HFC-143a and HFC-143. The testing methods are chosen based on the 
list of target analytes provided at each method.

    EPA is proposing these modifications to ensure that the testing 
methods used to verify the composition of all bulk HFCs can achieve at 
least the same accuracy as those specified in appendix A to 40 CFR part 
82, subpart F.
    Under the existing regulations at 40 CFR 84.5(i)(3)(ii), no person 
may sell or distribute, or offer for sale or distribution, regulated 
substances as a refrigerant that do not meet the specifications in 
appendix A to 40 CFR part 82, subpart F--Specifications for 
Refrigerants. EPA is proposing to clarify that this existing 
requirement is applicable for a regulated substance or mixture 
containing regulated substance(s). EPA is further proposing to add a 
requirement under 40 CFR 84.5(i)(3)(ii) that producers, importers, 
reclaimers, recyclers for fire suppression, or repackagers must verify 
the applicable specifications using the sampling and testing 
methodology prescribed in appendix A to 40 CFR part 82, subpart F.
    EPA is proposing these modifications to ensure that the testing 
methods used to verify the composition of all bulk HFCs offered for 
sale or distribution can achieve at least the same accuracy as those 
specified in appendix A to 40 CFR part 82, subpart F. All of these 
proposed requirements are intended to reduce the frequency that 
mislabeled, misrepresented, or off-specification regulated substances 
enter commerce from producers, importers, reclaimers, fire suppressant 
recyclers, and repackagers. EPA is also concerned that, without testing 
requirements, or specification around what sampling and testing 
methodology must be used, the composition of containers sold could not 
be sufficiently accurate, resulting in inaccurate quantities of 
consumption or production allowances expended.
    Collectively, the proposed changes will ensure that defined 
procedures will be used to perform testing on representative samples of 
single component HFCs or multicomponent HFC mixtures by all entities 
that produce, import, reclaim, recycle for fire suppression, or 
repackage HFCs. Regulated substances used as refrigerants must conform 
to the specifications provided in appendix A to 40 CFR part 82, subpart 
F, or, if not listed therein, the Generic Maximum Contaminant Levels in 
appendix A1 to 40 CFR part 82, subpart F. At a minimum, the proposed 
changes require that samples of single component regulated substance 
shall be quantitively analyzed for the component on the label, air and 
other non-condensable compounds, impurities (both volatile impurities 
and halogenated unsaturated volatile impurities), and high boiling 
residue. At a minimum, the proposed changes require that samples of 
multicomponent HFC mixtures shall be quantitatively analyzed for each 
component expected based on the container label, air and other non-
condensables, impurities (both volatile impurities and halogenated 
unsaturated volatile impurities), and high boiling residue.
    EPA believes that this testing regime is appropriate to determine 
the composition of HFCs sold for both refrigerant and non-refrigerant 
applications. The proposed methods for testing HFCs are provided in 
Table 3. For illustrative purposes, EPA is also noting the 
specifications for regulated substances in Table 4.

                                          composition on label.
------------------------------------------------------------------------

    The testing regime specified in AHRI 700 is sufficiently flexible 
to allow for the use of more recent analytical technology. Section 5 of 
appendix A to 40 CFR part 82, subpart F, entitled ``Sampling and 
Summary of Test Procedures,'' identifies the test methods in the 
section as ``referee tests'' and states that, ``[i]f alternative test 
methods are employed, the user must be able to demonstrate that they 
produce results at least equivalent to the specified referee test 
method.'' The referee test for refrigerant identification is specified 
in section 5.3 of appendix A as gas chromatography as described in 2008 
appendix C to AHRI Standard 700-2014 (incorporated by reference, see 
Sec.  82.168(b)(2)). Appendix C to AHRI Standard 700-2014 contains 
several different gas chromatography methods, specialized for different 
refrigerant types. Section 7 of each method in Appendix C to AHRI 
Standard 700-2014 provides information concerning the sensitivity, 
precision, and accuracy of that test method. Therefore, to demonstrate 
that an alternate test method is equivalent, it is sufficient to 
demonstrate that the alternate test method can achieve the same 
sensitivity, precision, and accuracy as the referee test method.
    EPA anticipates that alternate test methods could include gas 
chromatography using physical layer open tubular columns alternative to 
packed columns, two-dimensional alternatives to one-dimensional 
chromatography, and alternate detectors (e.g., mass spectrometer as an 
alternative to a flame ionization detector). Since Appendix C to AHRI 
Standard 700-2014 does not include specific test procedures for 
determining the quality of regulated substances that are not used as 
refrigerants, EPA is proposing using EPA Method 18 for HFC-227ea, HFC-
236cb, HFC-236ea, HFC-236fa, HFC-245ca, HFC-365mfc, HFC-43-10mee, 
isomers of listed regulated substances and mixtures of regulated 
substances not used as a refrigerant. EPA Method 18, ``Measurement of 
gaseous organic compound emissions by gas chromatography,'' can be 
found at Appendix A-6 to 40 CFR part 60--Test Methods 16 through 18. 
This method appears to be appropriate for the HFCs regulated under the 
AIM Act and would provide a well-established standard used in other EPA 
regulatory programs. EPA requests comment on whether this standard is 
appropriate to fill gaps in the requirements in appendix A to 40 CFR 
part 82, subpart F, or if EPA could rely on appendix A to 40 CFR part 
82, subpart F, including appendix A1 and the incorporated Appendix C to 
AHRI Standard 700-2014, for all sampling and testing requirements. EPA 
could finalize an approach that uses one or both standards.

[[Page 66394]]

    While the current testing and sampling requirement in 40 CFR 
84.5(i)(3) applies to entities producing, importing, reclaiming, 
recycling for fire suppression, or repackaging regulated substances, 
EPA seeks comment on whether to extend this requirement to exporters 
(or exporters that request additional consumption allowances under 40 
CFR 84.19) to verify the regulated substances being exported match the 
label and, where relevant, the request for additional consumption 
allowances. EPA also seeks comment on whether to extend the testing and 
sampling requirements to additional entities, including others that 
sell or distribute regulated substances, or that offer them for sale 
and distribution as well as those that transform, use as a process 
agent, destroy, or receive application-specific allowances in the six 
applications listed in subsection (e)(4)(B)(iv) of the AIM Act to 
further ensure the label matches the regulated substance in containers 
and aid in the detection of off-specification and potentially non-
compliant containers of regulated substances. Finally, EPA seeks 
comment on whether to establish purity and other specifications for 
non-refrigerants similar to those found in appendix A to 40 CFR part 
82, subpart F or if the proposed approach of requiring the label to 
match the nominal composition of regulated substance(s) in the 
container is sufficient to ensure purchasers know the contents of the 
container and that all entities can verify the number of allowances 
that needed to be expended when the regulated substances in the 
container were imported or produced.

B. Recordkeeping of Tests

    EPA proposes to modify the existing recordkeeping requirements in 
40 CFR 84.31 to specify that the types of records required to be 
maintained related to testing results includes instrument calibration, 
sample testing data files, and results summaries of both sample test 
results and quality control test results that are in a form suitable 
and readily available for review.
    Since the existing requirement in 40 CFR 84.5(i)(3)(i) requires 
fire suppressant recyclers \48\ and repackagers \49\ to test a 
representative sample of regulated substances before they are sold, EPA 
is proposing that the recordkeeping requirement for test records be 
extended from producers, importers, and reclaimers to include recyclers 
for fire suppression and repackagers to ensure sufficient records are 
maintained. Specifically, EPA is proposing to add a recordkeeping 
provision at 40 CFR 84.31(j)(3)(ii) and 84.31(k) requiring that 
recyclers for fire suppression and repackagers maintain dated records 
of batch tests of regulated substances packaged for sale or 
distribution, including information on instrument calibration, sample 
testing data files, and results summaries of both sample test results 
and quality control test results that are in a form suitable and 
readily available for review. This would support enforcement efforts if 
EPA identifies an off-specification or mislabeled container of 
regulated substances and needs to confirm proper testing was conducted 
to verify the contents of the container(s).
---------------------------------------------------------------------------

    \48\ Generally, an entity that collects used HFC fire 
suppressants and directly resells those recovered HFCs--with or 
without any additional reprocessing including testing for purity--to 
another person for reuse as a fire suppressant would qualify as a 
fire suppressant recycler (also referred to as a ``recycler for fire 
suppression'' in 40 CFR part 84, subpart A). A person that recovers 
and aggregates used HFC fire suppressants for distribution to 
another entity for reprocessing before being sold for reuse as a 
fire suppressant would not be a fire suppressant recycler. Reselling 
HFC fire suppressants that have already been recovered and 
subsequently reprocessed by another person would not be a fire 
suppressant recycler. In effect, a fire suppressant recycler is the 
first entity to reintroduce recovered HFC fire suppressants into the 
market use as fire suppressant. EPA requests comment on whether 
existing interpretations and guidance provide sufficient clarity on 
this issue or whether EPA should codify this explanation to provide 
a regulatory definition of fire suppressant recyclers.
    \49\ EPA views repackagers and cylinder fillers interchangeably 
under the regulations at 40 CFR part 84, subpart A, and would define 
repackagers as entities who transfer regulated substances, either 
alone or in a mixture, from one container to another container prior 
to sale or distribution or offer for sale or distribution. EPA 
requests comment on whether it should codify this explanation to 
provide a regulatory definition of repackagers.
---------------------------------------------------------------------------

    To align with the request for comment on whether to extend the 
testing and sampling requirements, EPA seeks comment on whether to 
extend this recordkeeping requirement to other entities, such as 
exporters.

C. Define ``Batch'' and ``Representative Sample'' and Clarify the 
Relationship Between These Terms

    In the Framework Rule, reclaimers, producers, and importers are 
required to maintain records of the results of ``batch tests'' of 
regulated substances. Producers and importers are required to keep 
``[d]ated records of batch tests of regulated substances packaged for 
sale or distribution'' (40 CFR 84.31(b)(3)(xi) and 40 CFR 
84.31(c)(2)(xvi)), whereas the requirement for reclaimers does not 
depend upon sale or distribution and echoes the language in the 
definition of ``reclaim.'' EPA is proposing to add requirements to 
maintain dated records of batch tests of regulated substances packaged 
for sale or distribution for fire suppressant recyclers and 
repackagers.
    The current rule specifies testing requirements for producers and 
importers only at 40 CFR 84.5(i)(3)(i), which requires testing of a 
``representative sample.'' Regulated substances sold as refrigerants 
must be sampled according to appendix A. Part 5.2, Refrigerant Sampling 
at 5.2.1 provides that ``[s]pecial precautions should be taken to 
ensure that representative samples are obtained for analysis.'' Since 
the rest of section 5.2 specifies methods for sampling refrigerants, it 
is clear that the intent of these sampling methods is to allow for the 
collection of representative samples of refrigerants. The sampling 
methods defined for refrigerants are specific to sampling of individual 
cylinders, which are commonly used in the sale of refrigerants, but may 
not cover all possible containers used for sales or distributions of 
refrigerants. EPA's proposed changes for regulated substances, both 
sold as a refrigerant and for other uses, is specified in the preceding 
section.
    EPA is proposing to include a definition of ``batch'' at 40 CFR 
80.3. EPA is proposing that a batch be defined as (1) A vessel, 
container, or cylinder from which a producer, importer, reclaimer, 
recycler, or repackager transfers HFCs directly for sale or 
distribution, or for repackaging for sale or distribution or (2) a 
population of small vessels, containers, or cylinders that a producer, 
importer, reclaimer, recycler, or repackager directly offers for sale 
or distribution.
    EPA is also proposing to define the term ``representative sample'' 
within the context of this regulation. EPA is proposing a two-part 
definition of representative sample. The first defines a representative 
sample of a container for sale as a sample collected from a container 
offered for sale or distribution using a sampling method that obtains 
all components of HFC(s) in an unbiased and precise manner. This 
definition is consistent with the implied notion of representative 
sample in appendix A of CFR part 82 Subpart F, which outlines specific 
methods for sampling containers. For the second part, EPA proposes to 
define a representative sample of a batch as a sample that can be used 
to infer that the composition of HFC(s) in a population of containers 
offered for sale or distribution that constitute, or are derived from, 
the batch are within stated tolerances (e.g., within the specifications 
established in the tables in section 6 of appendix A to 40 CFR part 82, 
subpart F, such as

[[Page 66395]]

composition and percent by volume air and other non-condensables).
    EPA is proposing to make these changes to allow for the common 
scenario when testing of a batch is used to satisfy the requirement for 
``testing of a representative sample'' to verify that the composition 
of HFCs in containers matches the container labeling, while also 
requiring that these batch test results produce valid labels for 
individual containers. These changes will help clarify the 
recordkeeping requirements associated with maintaining records of 
``batch tests.''

D. Laboratory Methods and Accreditation

    At 40 CFR 82.5(i)(2)(ii), EPA currently provides an option to 
importers that want to repackage regulated substances that were 
initially either unlabeled or mislabeled to ``[v]erify the contents 
with independent laboratory testing results and affix a correct label 
on the container that matches the test results before the date of 
importation (consistent with the definition at 19 CFR 101.1) of the 
container.'' But this requirement places no restrictions on what 
constitutes an ``independent laboratory'' nor on the quality of the 
analysis that the laboratory would have to achieve.
    EPA is proposing to define ``laboratory testing'' as the use of the 
sampling and testing methodology prescribed by a laboratory that is 
accredited to ISO 17025. EPA is proposing this change to make clear 
that laboratory testing means, for purposes of 40 CFR part 84, the use 
of the methods specified (or incorporated by reference) in appendix A 
to 40 CFR 82, subpart F and EPA Method 18, where appropriate. This 
ensures that laboratory testing undertaken pursuant to the 40 CFR part 
84 regulations uses a methodology that is consistent with the testing 
required for sales and distribution of HFCs, which will ensure 
consistency throughout the HFC regulatory environment. EPA is also 
proposing that laboratories must be accredited in order to be used for 
purposes of meeting the 40 CFR 84.5(i)(2)(ii) requirements. Laboratory 
accreditation bodies assess a variety of aspects of a laboratory, 
including the technical competence of staff; the validity and 
appropriateness of test methods; traceability of measurements and 
calibration to national standards; suitability, calibration, and 
maintenance of the testing environment; sampling, handling, and 
transportation of test items; and quality assurance of test and 
calibration data. In November 2017, International Organization for 
Standardization (ISO)/International Electrotechnical Commission (IEC) 
published a new version of the test laboratory accreditation standard, 
ISO/IEC 17025:2017. In addition to adding a definition of 
``laboratory,'' the new version replaces certain prescriptive 
requirements with performance-based requirements and allows for greater 
flexibility in satisfying the standard's requirements for processes, 
procedures, documented information, and organizational 
responsibilities. Interested persons may purchase a copy of ISO/IEC 
17025:2017 from the source provided in 40 CFR 84.37(b)(1), and it is 
available at https://www.techstreet.com/standards/iso-iec-17025-2017?product_id=2000100. This accreditation would ensure that 
laboratories follow good laboratory practices and that their operations 
have been reviewed by a recognized accreditation authority.
    EPA is seeking comment on whether to require that all testing under 
40 CFR 84.5(i)(3) be conducted by an independent and/or accredited 
laboratory. EPA understands that some entities have in-house 
laboratories and/or unaccredited laboratories that they currently rely 
upon for testing. Since the requirement for sampling and testing 
generally is in response to concerns about the potential for unlabeled 
or mislabeled container(s), the additional stringency of this 
requirement may be justified. However, EPA seeks comment on whether 
other safeguards are in place at laboratories that are currently 
typically used by this regulated community that are similar in nature 
to accreditation, such as certification by an independent third party, 
that would decrease the importance of testing being conducted by an 
independent and/or accredited laboratory.
    EPA is also seeking comment on whether AHRI Certified Refrigerant 
Testing Laboratory and others should be allowed in addition to ISO 
17025 laboratories. The AHRI certification program requires competence 
with the refrigerant testing requirements of appendix A, although the 
certification is not as rigorous as an ISO 17025 accreditation.

E. Certificate of Analysis for Imports of Regulated Substances

    To aid in the review and monitoring of imports of HFCs, EPA is also 
proposing to require that certificates of analysis records accompany 
all imports of regulated substances. Under this proposal, certificates 
of analysis would include the sampling and testing that is used to 
verify the composition of bulk regulated substance(s) offered for sale 
or distribution, and the proposed definitions will facilitate this 
recordkeeping when batch testing is used to satisfy the labeling 
requirement. EPA understands that certificates of analysis regularly 
accompany imports of HFCs currently and does not expect this 
requirement to change current practices. If finalized, it would provide 
EPA additional information to confirm the number of allowances that 
need to be expended at the time of import. Under this proposal, EPA 
would require that the certificate of analysis be made available to EPA 
on the same timeline as the advance notice required under 40 CFR 
84.31(c)(7).
    EPA seeks comment on whether EPA should require that the 
certificate of analysis that is provided and testing and sampling 
conducted prior to import be conducted by a laboratory accredited under 
ISO 17025. For the same reasons described in the prior section of this 
preamble, this accreditation would ensure that laboratories follow good 
laboratory practices and that their operations have been reviewed by a 
recognized accreditation authority.

VIII. What other revisions is EPA proposing?

    In addition to what is outlined in the prior sections, EPA is 
proposing a number of additional regulatory changes based on both 
lessons learned and current practices that have proved useful in 
implementing the HFC phasedown.

A. Define the Term ``Expend''

    Under the AIM Act and EPA's implementation of the HFC phasedown, a 
person must expend allowances to produce or import regulated substances 
outside of limited exceptions. In the Framework Rule, EPA did not 
codify a regulatory definition of ``expend'' in 40 CFR 84.3. EPA 
proposes to amend 40 CFR 84.3 to include a definition of expend. EPA 
proposes to define expend to mean to subtract the number of allowances 
required for the production or import of regulated substances under 40 
CFR part 84 from a person's unexpended allowances. We are proposing in 
section V.A of this preamble to codify the point in time that 
determines when calendar year allowances are expended, in section V.B 
of this preamble to codify that importers of record must expend 
allowances, and in section VI.B of this preamble to require same day 
recordkeeping of when producers and importers expend allowances that 
would be included in quarterly reports. EPA is proposing to add a 
regulatory definition of ``expend'' to accompany these proposed 
regulatory revisions to provide additional

[[Page 66396]]

specificity on how parties are required to implement these 
requirements.

B. Modify Labeling Requirements

    EPA codified certain labeling requirements in 40 CFR 84.5(i)(1), to 
require a person who is selling, distributing, offering for sale or 
distribution, or importing containers containing a regulated substance 
that the container include ``a label or other permanent markings 
stating the common name(s), chemical name(s), or American Society of 
Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 
designation of the regulated substance(s) or blend contained within, 
and the percentages of the regulated substances if a blend.'' EPA is 
proposing several changes to this regulatory text to provide additional 
detail on requirements, both to enable more transparency into the 
movement of HFCs and to help enable implementation and enforcement, 
where appropriate. Having accurate labeling of containers of regulated 
substances allows EPA, CBP, and other enforcement officials to quickly 
identify containers of interest, understand the contents of those 
containers, and make decisions about whether further inspection is 
warranted.
    EPA proposes revising 40 CFR 84.5(i)(1) to require a ``permanent 
label'' in place of ``a label or other permanent marking.'' In other 
regulatory programs, EPA has experienced situations where an entity has 
swapped out easily removable labels in anticipation of an upcoming 
inspection. During the phaseout of ODS, EPA is aware of instances where 
an importer would import cylinders labeled as containing HFCs (prior to 
enactment of the AIM Act), when in fact they contained regulated HCFCs. 
Shortly after import, the importer would relabel the cylinders and sell 
them as HCFCs in an attempt to circumvent the CAA prohibition on 
importing HCFCs without allowances. EPA is proposing to require a 
permanent label to avoid such situations and to prohibit tampering with 
the permanent label. EPA is soliciting comment on examples of 
situations where permanent labels may be appropriate and is also 
soliciting comment on what type of ``permanent marking'' may be 
available for use on the types of containers used for regulated 
substances that are consistent with other Federal requirements. EPA is 
also soliciting comment on whether there are reasons why regulated 
entities would benefit from the ability to use a ``permanent marking'' 
in place of a label. EPA is also soliciting comment on any 
implementation challenges associated with requiring a ``permanent 
label.'' EPA is also soliciting comment on any implementation 
challenges associated with requiring a ``permanent label.''
    To ensure that the labeling requirements meet their intended 
purpose, EPA is also proposing to add more detail and specificity on 
the regulatory labeling requirements. EPA proposes to make changes to 
the existing regulatory text at 40 CFR 84.5(i)(1) to include the 
following features such that all marks must be:
     Durable and printed or otherwise labeled on, or affixed 
to, the external surface of the bulk HFC container;
     Readily visible and legible;
     Able to withstand open weather exposure without a 
substantial reduction in visibility or legibility;
     Displayed on a background of contrasting color; and
     If a container of regulated substances is contained within 
a box or other overpack, the exterior packaging must contain legible 
and visible information in at least 20-point font of what regulated 
substance is contained within.
    These proposed revisions to the labeling requirements are intended 
to help ensure that all containers of regulated substances would 
contain labeling that is not easily manipulated, that would be easily 
visible and legible, and would contain information that is necessary 
for appropriate inspection and enforcement, as appropriate. As outlined 
in detail in the Framework Rule (86 FR 55166), the Agency has 
significant concerns about the potential for and impact of illegal 
trade in regulated substances. This concern is particularly heightened 
at the start of a new phasedown step. The requirements of the HFC 
phasedown are implemented at a variety of locations, including at 
border entries and industrial facilities. As a result, EPA relies on a 
diverse array of law enforcement officials to aid in compliance efforts 
related to the 40 CFR part 84 requirements. It is particularly 
important in light of these circumstances for EPA to strive to ensure a 
program that can be readily and efficiently implemented. Without 
appropriate labeling, containers of regulated substances may not be 
readily distinguishable from containers of other products. Accordingly, 
these proposed provisions would facilitate inspections by providing 
durable labels that clearly identify contents.
    As a complementary measure to these additional labeling 
requirements, EPA is proposing to add to the prohibitions at 40 CFR 
84.5(i)(2), that no one other than the importer of record may repackage 
or relabel regulated substances that were initially unlabeled or 
mislabeled. EPA is proposing to change the current text, which applies 
to importers, to allow only for the importer of record to undertake 
these actions. This is intended to parallel the proposals elsewhere in 
this preamble that would permit only an importer of record to expend 
allowances for the import of bulk regulated substances. Additionally, 
the current regulatory text does not preclude relabeling; it only 
precludes repackaging. However, this regulatory text is intended to 
apply to regulated substances that were ``initially mislabeled or 
unlabeled.'' While it is important to provide restrictions in such 
situations on repackaging, it is equally important to speak to 
relabeling for a scenario where the regulated substances are not moved 
into a different container.

C. Clarify Ability To Move Allowances Among Companies With Certain 
Affiliation Without a Transfer

    EPA made clear in the Framework Rule that in calculating the 
quantity of allowances to allocate, ``for purposes of determining the 
quantity of past imports, EPA is treating all companies majority owned 
and/or controlled by the same individual(s) as a single company, even 
if there is no corporate parent'' (86 FR 55145). EPA also considers all 
parent, \50\ subsidiary,\51\ sister,\52\ and commonly owned \53\ 
companies together in determining past imports. Complementarily, it is 
EPA's longstanding practice that allowances can be expended by parents, 
subsidiaries, sister, or commonly owned companies without a transfer. 
EPA is proposing to revise the regulatory text at 40 CFR 84.19(a) to 
codify this practice for additional clarity for allowance holders.
---------------------------------------------------------------------------

    \50\ In referring to a parent, EPA means a company that has a 
majority, i.e. at least fifty percent, stake in another company.
    \51\ In referring to a subsidiary, EPA means a company that is 
majority, i.e. at least fifty percent, owned by another company.
    \52\ In referring to a sister company, EPA means an entity 
related to another entity by a shared corporation with majority 
ownership.
    \53\ In referring to a commonly owned company, EPA means a 
company that is related to another company by a shared individual 
owner or owners, where there is at least (1) a single individual 
that owns 30 percent or more of each company or (2) individuals with 
direct family relationships (parent, child, sibling, or spouse) that 
own a majority of each company.
---------------------------------------------------------------------------

    Given that EPA considers historic activity together for these 
companies in determining a single quantity of allowances to allocate, 
it is appropriate to allow companies in this situation to expend from 
the single pool of allowances through different arms of its corporate 
chain. Therefore, it seems

[[Page 66397]]

inappropriate to require a transfer, including a petition to the Agency 
and a transfer offset, when EPA considers these commonly owned 
companies as a single entity for purposes of calculating and allocating 
allowances. However, EPA invites comments on potential negative 
implications of this proposal. EPA requests comment on whether the 
proposed revisions to the text adequately capture the appropriate 
entities.

D. Revise Required Elements To Request Additional Consumption 
Allowances

    In the Framework Rule EPA created a process by which a person may 
obtain consumption allowances equivalent to the quantity of regulated 
substances exported by that person. Given that the AIM Act subtracts 
exports in the definition of ``consumption'' under subsection (b)(3), 
it is consistent with the Act to refund consumption allowances that 
were expended to import or produce regulated substances if those 
regulated substances were later exported from the country. An exporter 
must submit certain information (40 CFR 84.17(a)) for EPA's review to 
verify that the regulated substances were in fact exported.
    Through implementation of the existing 40 CFR 84.17 regulations, 
EPA has learned that the review of requests for additional consumption 
allowances (RACAs) could be more efficient if exporters provided 
additional information with their RACA requests. Specifically, EPA is 
proposing to require that RACA applicants submit the following 
additional data points: (1) Internal Transaction Numbers (ITNs) for all 
shipments regardless of monetary value, destination country, or other 
characteristics that could otherwise exempt or preclude an exporting 
entity from obtaining an ITN, (2) conveyance names, (3) IMOs of the 
vessel(s) carrying the export, as applicable and (4) container numbers 
(e.g., ISO tank numbers). Inclusion of this additional information 
would aid EPA in verifying reported exports through CBP data. These 
proposed additional data points should help ensure that EPA can quickly 
locate exports and review RACA applications expeditiously. An ITN is 
received as confirmation that the Electronic Export Information (EEI) 
has been accepted in the Automated Export System (AES). EPA notes that 
there are some exports where an exporter is not required to receive an 
ITN. This may be the case for certain exports destined for Canada or 
valued under $2,500, for example. This proposal would require that all 
exports of regulated substances have associated EEI that is filed by 
way of AES, regardless of whether the exports are destined for Canada, 
under a low value threshold, or otherwise not required to have an ITN. 
EPA requests comment on whether there are any additional data points 
that would aid the Agency in quickly verifying the information provided 
in a RACA application, including but not limited to customs release 
documents from the country receiving the exports and proof of receipt 
at the final destination. EPA also requests comment on whether any 
entity that may apply for a RACA would have difficulty gathering and 
submitting the additional data points proposed here. EPA's 
understanding is that these data points appear on existing bills of 
lading, although the specific data points on a given bill of lading may 
differ by broker.
    EPA is also taking comment on whether the Agency should require the 
reporting of certain EEI, which are data that must be filed through 
AES, to aid in EPA's review of RACAs and to verify export data more 
generally similar to those required (and proposed to be required) under 
40 CFR 84.31(c)(7), such as cargo description, gross and net weight, 
unit of mass (i.e., kilograms), HTS Code, container number(s) of the 
shipment (if applicable), vessel name and the IMO number, where 
applicable, CAS Number(s) of the regulated substance(s) imported and, 
for regulated substances that are in a mixture, either the ASHRAE 
numerical designation of the refrigerant or the percentage of the 
mixture containing each regulated substance.
    Finally, while the current RACA requirements allow an entity to 
receive a refund on allowances for an export regardless of when the HFC 
was initially produced or imported, EPA is considering amending the 
regulations to require that exporters provide documentation to verify 
an allowance was expended when the regulated substance being exported 
was produced or imported. This could reduce the opportunity for an 
entity to illegally import an HFC, export it legally, and receive a 
legal consumption allowance, effectively allowing a bad actor to 
launder smuggled HFCs. It would also reduce the opportunity for 
entities to receive RACAs for stockpiled HFCs imported or produced 
prior to 2022. EPA noted its concern in the proposed Framework Rule 
that an entity could over produce or import high-GWP HFCs prior to 
January 1, 2022, and export them to gain additional allowances in later 
years. In the Framework Rule, EPA initially proposed that RACAs would 
only be available for regulated substances that were produced or 
imported in the same year as the export occurred, but did not finalize 
that time restriction noting that it could be unnecessarily 
prescriptive, cause challenges around the change in calendar year, and 
the challenges such a requirement would have for net exporters who are 
not allocated allowances at the start of the year since their historic 
consumption would be negative. EPA seeks comment on whether these 
reasons will still be valid by 2024 and also whether it is appropriate 
to finalize a requirement with some more flexible time-related 
restriction.

E. Petitions To Import Regulated Substances for Laboratory Testing with 
Eventual Destruction

    EPA's regulations codified in 40 CFR 84.25(b) detail the process by 
which entities can import used regulated substances into the United 
States for destruction without expending allowances. The Framework Rule 
explained that used HFCs may need to be destroyed when they are 
contaminated beyond the point that reclamation is economical, and that 
providing a pathway to import used HFCs for proper disposal in the 
United States can benefit the environment and the domestic destruction 
industry (86 FR 55181). The Agency explicitly excluded importing virgin 
HFCs for disposal from the petition process, stating that ``Importing 
virgin HFCs, even for disposal, requires the expenditure of consumption 
allowances.''
    In reviewing import activity, EPA has learned that some entities 
may import small amounts of regulated substances for laboratory testing 
to determine the type and amount of any impurities in the United 
States, after which point the substances are destroyed. In such 
situations the regulated substances are virgin material, but may not 
meet the exact specifications required by the producer or for the 
intended applications. The current regulations require allowances to be 
expended in these instances, as these materials are not used regulated 
substances. Even if these regulated substances could be considered 
used, there are no provisions in the current regulations to allow for 
an intermediary step (such as laboratory testing) prior to destruction 
without expending allowances.
    Based on current information, EPA does not consider laboratory 
testing of regulated substances that are ultimately bound for 
destruction as meriting an exemption from expending allowances. EPA 
established a regulatory petition process for other situations where

[[Page 66398]]

regulated substances are imported without expending allowances, such as 
for feedstock uses or disposal by destruction. Those standardized 
processes provide a means for EPA to document shipments, verify that 
the intended functions are being carried out, and expedite reviews. In 
the case of laboratory testing with eventual destruction, the 
frequency, quantity, and number of potentially affected entities are 
not fully known, though the Agency does not believe that that they are 
sufficient enough in scale to necessitate a regulatory petition process 
for the entities to be exempt from expending allowances. The Agency 
currently lacks compelling reasons or rationale for why such testing 
cannot be performed in the country of use. Nonetheless, EPA is 
soliciting comment on whether a petition process like that in 40 CFR 
84.25(b) would be appropriate and necessary, and on the number of 
entities that would potentially make use of a petition process as well 
as the frequency and quantity of such imports. If compelling comments 
are received demonstrating that these tests cannot be performed in the 
countries of use or that the scope of these activities warrant a 
regulatory petition process, EPA would consider finalizing a process as 
outlined further in this section.
    Should EPA determine there is need for such a petition process, EPA 
is taking comment on whether a petition process should be provided, by 
which allowances would not be necessary for importing virgin or used 
regulated substances exclusively for laboratory testing for the type 
and quantity of impurities, where the regulated materials are 
ultimately bound for destruction.
    Specifically, EPA is taking comment on a process for which imports 
of regulated substances could qualify if they are imported for 
laboratory testing and ultimately bound for destruction and are limited 
to 0.5 kg per shipment, and that a person must petition the Agency for 
the import of each individual shipment of a regulated substance that 
met these criteria in order to not expend allowances. If EPA were to 
determine such a process is needed, it is taking comment on including 
the following requirements in that process: a petition would be 
required at least 30 days before the shipment is to arrive at a U.S. 
port, containing the following information:
     Name, HTS code, and quantity in kilograms (limited to 0.5 
kg) of each regulated substance to be imported;
     Name and address of the importer, the importer 
identification number, and the contact person's name, email address, 
and phone number;
     Name and address of the consignee and the contact person's 
name, email address, and phone number;
     Name and address of any intermediary who will hold the 
imported regulated substances for laboratory testing, and the contact 
person's name, email address, and phone number;
     Name and address of any intermediary who will hold the 
imported regulated substances for destruction, and the contact person's 
name, email address, and phone number;
     Source country;
     An English translation, if needed, of the export license 
(or application for an export license) from the appropriate government 
agency in the country of export;
     The U.S. port of entry for the import, the expected date 
of import, and the vessel transporting the material. If at the time of 
submitting the petition the importer does not know this information, 
and the importer receives a non-objection notice for the individual 
shipment in the petition, the importer is required to notify the 
relevant Agency official of this information prior to the entry of the 
individual shipment into the United States;
     Name, address, contact person, email address, and phone 
number of the responsible party at the laboratory testing facility;
     Name, address, contact person, email address, and phone 
number of the responsible party at the destruction facility;
     A certification from the importer attesting that prior to 
destruction, the regulated substances are only being imported for 
testing to determine the type and quantity of impurities with no other 
use;
     A certification from the laboratory conducting the testing 
that they will only distribute the regulated substances to the 
destruction facility specified in the petition after testing is 
complete and will send the regulated substances to the destruction 
facility within 60 days of receipt; and
     A certification from the destruction facility that they 
will destroy the regulated substance within 45 days of receipt.
    EPA is further taking comment on using a review process, time by 
which the regulated substances must be destroyed, quantity (in MTEVe) 
limits, proof of destruction requirements, and recordkeeping provisions 
for the petition process described above in this section, that would be 
similar to those currently codified in 40 CFR 84.25 (b)(2)-(6). Finally 
with respect to this petition process, the Agency is taking comment on 
requiring that the laboratory performing the purity testing submit to 
EPA information demonstrating and confirming that the regulated 
substances have been delivered to a destruction facility in accordance 
with approved technologies in 40 CFR 84.29 within 15 calendar days of 
the destruction facility receiving the regulated substances.

IX. What are the costs and benefits of this proposed action?

    In the Framework Rule, EPA conducted a Regulatory Impact Analysis 
(RIA) which estimated the costs and benefits of implementing the 
phasedown of HFCs as a result of the passage of the AIM Act, as 
realized by promulgating that rule. This action proposes to follow an 
allocation methodology and framework nearly identical to that rule, and 
this action is not expected to result in significant changes to the 
phasedown program as a whole or fundamentally change the assumptions 
made in the RIA. As described in this preamble, we are proposing to 
adjust the consumption baseline, revise particular recordkeeping and 
reporting requirements, and carry out other limited revisions to the 
existing regulations. These revisions would generally apply from the 
years 2024 and beyond. In this section we discuss two discrete changes 
to the analysis of benefits and costs as presented in the RIA for the 
Framework Rule. First, we are providing an analysis of the incremental 
change in benefits and costs associated with the proposed adjustment to 
the consumption baseline from 2024 through 2050 relative to the 
benefits and costs estimate for the same time period as estimated in 
the supporting analysis for the Framework Rule. Secondly and 
separately, we have adjusted estimated costs associated with the HFC 
phasedown from 2024 through 2050 due to updating assumptions for an 
abatement option used in the analysis.
    This analysis is intended to provide the public with updated 
information on the relevant costs and benefits of this action and to 
comply with Executive Orders. The analysis does not form a basis or 
rationale for any of the actions EPA is proposing in this rulemaking. 
The Framework Rule, its RIA, and supporting documentation provide more 
detail on our analysis methodology of the costs and benefits of the HFC 
phasedown between 2022 and 2050, and are available in the docket for 
this action (Docket ID No. EPA-HQ-OAR-

[[Page 66399]]

2022-0430). More information on the analysis for this action is 
available in an addendum to the Framework Rule's RIA in the docket for 
this action.
    As discussed in section IV of this preamble, this rule proposes to 
reduce the consumption baseline by 3.6 million metric tons of exchange 
value equivalent (MMTEVe) (approximately 1.2 percent) relative to the 
baseline codified in the Framework Rule at 40 CFR 84.7(b)(2). With a 
lower consumption baseline, more abatement will be necessary in each 
year starting in 2024 to reduce HFC consumption from its business-as-
usual level to a level below the maximum allowed consumption. However, 
for the years 2029 through 2035, the abatement options modeled 
previously using the higher baseline had already lowered consumption 
below the maximum consumption allowed. This ``overshoot'' reached a 
level of consumption that is already below the maximum consumption that 
would be allowed with the lowered baseline, so no additional abatement 
options are needed in these years and no incremental costs are accrued. 
More detail is provided in the RIA addendum for this rule. Assuming EPA 
finalizes the proposed change, using the same abatement option approach 
as used in the Framework Rule RIA, we estimate consumption will 
decrease relative to the business-as-usual forecast by an additional 
22.3 MMTEVe through 2050 (i.e., 7,183 MMTEVe compared with the previous 
estimate of 7,160 MMTEVe).
    Reducing the consumption of HFCs reduces the emissions of HFCs, 
although the time profile of emissions reduction can vary depending on 
the application the HFCs are used in because consumption in some 
applications, e.g., aerosols, may result in an immediate emissions 
release, while others, e.g., closed-cell foams, emit the HFCs used to 
produce them over many years. Thus, the percentage reduction in a 
discounted stream of consumption may not match the percentage reduction 
in a discounted stream of emissions. EPA's Vintaging Model is used to 
calculate consumption and emissions under a ``business-as-usual'' 
forecast and an alternative scenario in which the AIM Act allowance 
allocation phasedowns are in effect and abatement options are 
undertaken. The difference results in the reduction in consumption as 
well as the reduction of emissions of HFCs in each year. The 2024-2050 
total reduction in emissions of regulated HFCs from the proposed 
reduction in the consumption baseline is estimated to be 2 MMTEVe fewer 
relative to the previous estimate from the Framework Rule. By 
multiplying the change in emissions of each HFC in each year by the 
social cost of HFCs for that HFC for that year, the monetary value of 
the climate benefits of the emissions reduction can be estimated. These 
reductions in HFC consumption, emissions, and associated climate 
benefits, are all attributable to the baseline adjustment. From 2024 
through 2050 at a discount rate of 3 percent in 2020 dollars and 
discounted to 2022, this proposed baseline adjustment would result in 
incremental climate benefits of $125 million, costs of $1.2 billion, 
and a net cost of $1.1 billion. Relative to the present value of 
cumulative net benefits for the HFC Allocation Program between 2022 and 
2050, this increase represents a 0.4 percent decrease in cumulative net 
benefits. Although EPA is using the social costs of HFCs for purposes 
of this analysis, this proposed action does not rely on the estimates 
of these costs as a record basis for the Agency action, and EPA would 
reach the proposal conclusion even in the absence of the social costs 
of HFCs.
    EPA also updated an abatement option used in the analysis to 
reflect the most recently available information. Specifically, the 
previous analysis assumed that some consumption of HFC-134a could be 
abated by transitioning the foam-blowing agent used to produce extruded 
polystyrene (XPS) boardstock foam. If XPS foam producers shifted from 
using a combination of HFC-134a and carbon dioxide to a mixture of 
liquid carbon dioxide (LCD) and alcohol, all of the HFC consumption 
associated with producing XPS foam could be avoided. However, EPA 
received comment from two foam manufacturers that the abatement option 
of using LCD/alcohol has not been proven to meet the safety and 
performance standards required in the United States and would not be a 
viable option. While the LCD/alcohol technology is successfully used in 
other countries, we understand that U.S. companies expect XPS foam 
production to transition from using HFC-34a/CO2 to blends 
containing a hydrochlorofluoroolefin (HCFO) and/or a hydrofluoroolefin 
(HFO). This revision of an abatement option did not result in any 
changes to the emissions or benefits, because these options are applied 
to reduce consumption to the respective phasedown step. The updated 
assumption resulted in a cost increase of $2.7 billion from 2024-2050 
at a 3 percent discount rate relative to the prior estimate provided 
with the Framework Rule RIA. The effect is a one percent change in the 
estimated net benefit of the HFC phasedown in 2022-2050. This revision 
solely reflects a change in assumptions. It is not the result of a 
regulatory change and does not reflect a change in costs from actions 
proposed in this rule. EPA requests comment on this assumption, 
including on the modeled transition and estimated cost, and other 
transition scenarios described in the RIA addendum in the docket.
    For informational purposes, considering the incremental change to 
the consumption baseline associated with this proposed rule and the 
separate update to the analytical model described further in the 
addendum in the docket for this rulemaking, the present value of 
cumulative net benefits for the HFC Allocation Program between 2022 and 
2050 is now estimated to be $268.9 billion.

X. How is EPA considering environmental justice?

    As part of the RIA addendum for this proposed rule, EPA updated the 
environmental justice analysis that was previously conducted for the 
Framework Rule. The updated environmental justice analysis used the 
same analytical approach used previously, along with updated data on 
cancer and respiratory risks. The analysis also includes the addition 
of another facility that reported HFC production. Furthermore, as 
described in section VI.D of this preamble, EPA is also proposing to 
require that HFC production facilities report annual emissions of HAP, 
ODS, and HFCs from their HFC production lines.
    Executive Order 12898 (59 FR 7629, February 16, 1994) and Executive 
Order 14008 (86 FR 7619, January 27, 2021) establish Federal executive 
policy on environmental justice. Executive Order 12898's main provision 
directs Federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on people of color and low-income populations 
in the United States. EPA defines environmental justice as the fair 
treatment and meaningful involvement of all people regardless of race, 
color, national origin, or income with respect to the development, 
implementation, and enforcement of environmental laws,

[[Page 66400]]

regulations, and policies.\54\ Meaningful involvement means that: (1) 
Potentially affected populations have an appropriate opportunity to 
participate in decisions about a proposed activity that will affect 
their environment and/or health; (2) the public's contribution can 
influence the regulatory Agency's decision; (3) the concerns of all 
participants involved will be considered in the decision-making 
process; and (4) the rule-writers and decision-makers seek out and 
facilitate the involvement of those potentially affected.\55\ The term 
``disproportionate impacts'' refers to differences in impacts or risks 
that are extensive enough that they may merit Agency action. In 
general, the determination of whether there is a disproportionate 
impact that may merit Agency action is ultimately a policy judgment 
which, while informed by analysis, is the responsibility of the 
decision-maker. The terms ``difference'' or ``differential'' indicate 
an analytically discernible distinction in impacts or risks across 
population groups. It is the role of the analyst to assess and present 
differences in anticipated impacts across population groups of concern 
for both the baseline and proposed regulatory options, using the best 
available information (both quantitative and qualitative) to inform the 
decision-maker and the public.\56\

Environmental Justice During the Development of an Action.''

---------------------------------------------------------------------------

    A regulatory action may involve potential environmental justice 
concerns if it could: (1) Create new disproportionate impacts on people 
of color, low-income populations, and/or indigenous peoples; (2) 
exacerbate existing disproportionate impacts on people of color, low-
income populations, and/or indigenous peoples; or (3) present 
opportunities to address existing disproportionate impacts on people of 
color, low-income populations, and/or indigenous peoples through the 
action under development.
    Executive Order 14008 calls on agencies to make achieving 
environmental justice part of their missions ``by developing programs, 
policies, and activities to address the disproportionately high and 
adverse human health, environmental, climate-related and other 
cumulative impacts on disadvantaged communities, as well as the 
accompanying economic challenges of such impacts.'' Executive Order 
14008 further declares a policy ``to secure environmental justice and 
spur economic opportunity for disadvantaged communities that have been 
historically marginalized and overburdened by pollution and under-
investment in housing, transportation, water and wastewater 
infrastructure, and health care.'' In addition, the Presidential 
Memorandum on Modernizing Regulatory Review calls for procedures to 
``take into account the distributional consequences of regulations, 
including as part of a quantitative or qualitative analysis of the 
costs and benefits of regulations, to ensure that regulatory 
initiatives appropriately benefit, and do not inappropriately burden 
disadvantaged, vulnerable, or marginalized communities.'' EPA also 
released its June 2016 ``Technical Guidance for Assessing Environmental 
Justice in Regulatory Analysis'' (2016 Technical Guidance) to provide 
recommendations that encourage analysts to conduct the highest quality 
analysis feasible, recognizing that data limitations, time and resource 
constraints, and analytic challenges will vary by media and 
circumstance.
    In the Framework Rule, EPA established the baselines for the 
production and consumption of regulated substances, determined the 
quantity of allowances that would be available nationwide according to 
the AIM Act's phasedown schedule, and created an allowance allocation 
and trading program. EPA also summarized the public health and welfare 
effects of GHG emissions (including HFCs), including findings that 
certain parts of the population may be especially vulnerable to climate 
change risks based on their characteristics or circumstances, including 
the poor, the elderly, the very young, those already in poor health, 
the disabled, those living alone, and/or indigenous populations 
dependent on one or limited resources due to factors including but not 
limited to geography, access, and mobility (86 FR 55124-55125). 
Potential impacts of climate change raise environmental justice issues. 
Low-income communities can be especially vulnerable to climate change 
impacts because they tend to have more limited capacity to bear the 
costs of adaptation and are more dependent on climate-sensitive 
resources such as local water and food supplies. In corollary, some 
communities of color, specifically populations defined jointly by both 
ethnic/racial characteristics and geographic location, may be uniquely 
vulnerable to climate change health impacts in the United States.
    EPA has not assessed climate-based impacts to communities that 
surround HFC production facilities for this rule or as part of the 
Framework Rule. The location of HFC production facilities has no 
significant bearing on the climate impacts that these communities will 
experience.
    As detailed in the Framework Rule and its accompanying RIA, the 
phasedown of HFCs in the United States will achieve significant 
benefits associated with reducing climate change. However, as described 
in the RIA for the Framework Rule and in the addendum for this proposed 
rule, there continues to be significant uncertainty about how the 
phasedown of HFC production, the issuance of allowances, and market 
trends independent of this proposed rulemaking could affect production 
of HFCs and HFC substitutes--and associated air pollution emissions--at 
individual facilities, particularly in communities that are 
disproportionately burdened by air pollution. The manner in which 
producers transition from high-GWP HFCs could drive changes in future 
risk for communities living near facilities that produce HFCs, to the 
extent the use of toxic feedstocks, byproducts, or catalysts changes 
and those chemicals are released into the environment with adverse 
local effects.
    For the environmental justice analysis performed to support the 
Framework Rule, as a starting point for assessing the need for a more 
detailed environmental justice analysis, EPA reviewed the available 
evidence from the published literature and from community input on what 
factors may make population groups of concern more vulnerable to 
adverse effects (e.g., cumulative exposure from multiple stressors), 
including but not limited to the 2009 and 2016 Endangerment Findings 
and the reports from IPCC, the U.S. Global Change Research Program, and 
the National Research Council. It was also important to evaluate the 
data and methods available for conducting an environmental justice 
analysis.
    EPA's 2016 Technical Guidance does not prescribe or recommend a 
specific approach or methodology for conducting an environmental 
justice analysis, though a key consideration is consistency with the 
assumptions underlying other parts of the regulatory analysis when 
evaluating the baseline

[[Page 66401]]

and regulatory options. Where applicable and practicable, the Agency's 
RIA examined certain metrics for an environmental justice analysis 
comprising more than just climate change effects, including: the 
proximity of entities receiving allowances to populations disaggregated 
by race and ethnicity, low-income populations, and/or indigenous 
peoples; the number of entities receiving allowances that may be 
adversely affecting population groups of concern; the nature, amounts, 
and location of regulated HFC production that may adversely affect 
population groups of concern; and potential exposure pathways 
associated with the production of the regulated HFCs or with chemicals 
used as feedstocks, catalysts, or byproducts of HFC production unique 
to particular populations (e.g., workers). The environmental justice 
analysis is described in the RIA for the Framework Rule and is based on 
public data from the TRI, GHGRP, EJSCREEN (an environmental justice 
mapping and screening tool developed by EPA), Enforcement and 
Compliance History Online (ECHO), and Census data. In addition, the 
analysis integrated suggestions received during the public comment 
period to the extent possible. The environmental justice analysis also 
contains information on non-production releases (as defined by TRI), 
water releases, and offsite disposal for chemicals used in HFC 
production. The analysis of potential environmental justice concerns 
focused mainly on characterizing baseline emissions of air toxics that 
are also associated with chemical feedstock use for HFC production. As 
noted in the RIA for the Framework Rule, there is uncertainty around 
the role that HFC production plays in emissions of these air toxics. In 
addition, EPA conducted a proximity analysis to examine community 
characteristics within one and three miles of these facilities. The 
Agency also explored larger radii (5 and 10 miles) in response to 
public comments that releases from these facilities may travel longer 
distances.
    The relatively small number of facilities directly affected by this 
rule enabled EPA to assemble a uniquely granular assessment of the 
characteristics of these facilities and the communities where they are 
located. The environmental justice analysis, which examines racial and 
economic demographic and health risk information, found heterogeneity 
in community characteristics around individual facilities. The analysis 
showed that the total baseline cancer risk and total respiratory risk 
from air toxics (not all of which are due to emissions from HFC 
production) varies, but is generally higher, and in some cases much 
higher, within one to ten miles of an HFC production facility. The 
analysis also found that higher percentages of both low-income and 
Black or African American individuals live near several HFC production 
facilities compared with the appropriate national and state level 
average. EPA noted in the final rulemaking, and reiterates here, that 
it is not clear the extent to which these baseline risks are directly 
related to HFC production, but some feedstocks, catalysts, and 
byproducts are toxic, particularly with respect to potential 
carcinogenicity (e.g., carbon tetrachloride, tetrachloroethylene, and 
trichloroethylene). All HFC production facilities are near other 
industrial facilities that could contribute to the AirToxScreen 
cumulative cancer and respiratory risk; the number of neighboring TRI 
facilities within one mile of an HFC production facility ranges from 2 
to 14, within 3 miles there are 2 to 19 neighboring TRI facilities, 
within 5 miles there are 2 to 34 neighboring TRI facilities, and within 
10 miles there are 6 to 66 neighboring TRI facilities.
    At this time, it is not clear how emissions related to HFC 
production compare to other chemical production at the same or nearby 
facilities. Additionally, some HFC alternatives, such as 
hydrofluoroolefins (HFOs), use the same chemicals as feedstocks in 
their production or release the same chemicals as byproducts, 
potentially raising concerns about local exposure. Emissions from 
production facilities manufacturing non-fluorinated substitutes (e.g., 
hydrocarbons, ammonia) could also be affected by the phasedown of HFCs. 
However, there is still limited information regarding how much of each 
substitute would be produced, which substitutes would be used, and what 
other factors might affect production and emissions at those locations, 
so it continues to be unclear to what extent this rule may affect 
baseline risks from hazardous air toxics for communities. Further, the 
HFC phasedown schedule prescribed by Congress--with a 40 percent 
reduction by 2024, a 70 percent reduction by 2029, an 80 percent 
reduction by 2034 and an 85 percent reduction by 2036--may also reduce 
the potential for a facility to increase emissions above current levels 
for a prolonged period, if at all.
    For this proposed rulemaking, EPA is updating the environmental 
justice analysis that was done as part of the Framework Rule. Not much 
time has elapsed since this rule was signed last September, and the 
Agency still does not have enough data to determine how the 
implementation of the HFC phasedown may affect production and emissions 
at facilities that produce HFCs and their substitutes. For this reason, 
EPA is following the analytical approach used in the Framework Rule RIA 
to provide updated data on the total number of TRI facilities near HFC 
production facilities and the cancer and respiratory risks to 
surrounding communities. This update includes the use of the most 
recent data available for the AirToxScreen data set from 2017, 
replacing the 2014 NATA data used in the previous analysis. 
Additionally, EPA is updating the list of HFC production facilities as 
part of this analysis to include an additional ninth facility that 
reported production of HFCs in 2022.
    Finally, EPA is including a demonstration of a microsimulation 
approach to analyze the proximity of communities to potentially 
affected HFC production facilities. Microsimulation is a technique 
relying upon advanced statistics and data science to combine disparate 
survey and geospatial data. It has long been used in a variety of 
economic and social science research and has been used before by EPA 
(in the context of understanding the implications of underground 
storage tank impacts on groundwater). Recent advances in data science 
and computational power have increased the availability of 
microsimulation for applications such as environmental justice 
analysis. The demonstration analysis included in the RIA addendum 
contributes to understanding communities that may warrant further 
environmental justice analysis.
    The updated environmental justice analysis found that for eight of 
the nine facilities identified as HFC producers, the demographic data 
are identical to that included in the Framework Rule RIA. The racial, 
ethnic, and income figures for the 8 communities within 1, 3, 5, and 10 
miles of the respective facilities are drawn from the most recent 
American Communities Survey data from 2019. Using the updated 2017 
AirToxScreen data, the total cancer risk and total respiratory risk 
generally decreased compared with the previous analysis for the 
communities surrounding several production facilities. The exception is 
the apparent rise in total cancer risk within one mile of the Mexichem 
Fluor facility in St. Gabriel, LA. The total cancer risk identified 
using the 2014 NATA data was 180 per million at a one-mile

[[Page 66402]]

radius. Using the 2017 AirToxScreen dataset, the total cancer risk 
rises within one mile of the facility to 200 per million. However, 
further from the facility, the total cancer risk was lower using the 
updated 2017 AirToxScreen data compared with that identified using the 
2014 NATA data. In particular, the total cancer risk drops to 130 per 
million from 140 per million within the three-mile radius, 120 per 
million from 140 per million within the five-mile radius, and further 
to 82 per million from 98 per million within the 10-mile radius. The 
total respiratory risk near the facility appears lower using the new 
data. Additionally, looking across the nine HFC production facilities, 
the risks from air emissions (not all of which necessarily stem from 
HFC production), while varied, were still generally higher, and in some 
cases much higher, within one to three miles of an HFC production 
facility and compared with the overall national and state averages.
    For the additional ninth facility, Islechem, the total cancer risk 
and total respiratory risk within 1 to 10 miles of the facility were 
similar to or lower than the risks based on the national and state 
average. The proportion of low-income and Black or African American and 
other communities of color were lower than the national and state 
averages and increased with increasing distance from this facility.
    As mentioned above in this section, emissions from facilities 
producing fluorinated and non-fluorinated substitutes may also be 
affected by the phasedown of HFCs. For the forthcoming proposed 
technology transitions rulemaking under the AIM Act, EPA is conducting 
an environmental justice analysis to assess the potential impacts of 
that proposed rule by examining the characteristics of communities near 
facilities producing HFC substitutes (e.g., hydrocarbons, 
CO2, ammonia, HFOs) used in the sectors or subsectors 
addressed in the petitions. More information will be provided in 
conjunction with that proposed rule, which the Agency anticipates 
publishing later this year.
    EPA seeks input on the environmental justice analysis contained in 
the RIA addendum for this proposed rule, as well as broader input on 
other health and environmental risks the Agency should assess. To 
support the development of comments, EPA is seeking data or analysis to 
identify whether it is reasonable to expect net increases in emissions, 
and if so how we might isolate the impacts of this program (e.g., 
effects resulting from the phasedown itself, the trading of production 
allowances, or some other factor) that would enable the Agency to 
conduct a more nuanced analysis of changes in releases associated with 
chemical feedstocks and byproducts for HFC substitutes, given the 
inherent uncertainty regarding where, and in what quantities, 
substitutes will be produced.
    EPA seeks comment and further discussion of the use of 
microsimulation approaches and techniques for regulatory impact 
analysis and other program activities. For example, what 
microsimulation tools are appropriate for better understanding the 
burdens faced by communities, and in what circumstances? The 
demonstration analysis presented in this RIA addendum uses a dataset of 
``synthetic households'' based on geospatial data combined through 
microsimulation techniques with information from the U.S. Decennial 
Census and the American Communities Survey (ACS). What other surveys or 
other geospatial datasets should be the focus of EPA efforts to combine 
with the ACS and/or Decennial Census data? How can microsimulation 
tools supplement other EPA tools for understanding demographics, 
multiple burdens facing communities, and assessing the impact of EPA 
programs? Can microsimulation and other techniques to use current 
survey information be used to identify data gaps which might be filled 
with refinements or improvements to existing survey tools?
    For the final rule, EPA is also considering updating the analysis 
to estimate exposure of the communities near the identified facilities 
to toxics using the Risk Screening Environmental Index Geographic 
Microdata (RSEI-GM). The Agency seeks comment on whether updating the 
analysis provided with the Framework Rule would be useful and what 
additional insight it might provide for the environmental justice 
analysis.
    EPA is taking comment on whether the proposal to require annual 
reporting of certain emissions, as described in more detail above in 
section VI.D of this preamble, would allow for the effective monitoring 
of these emissions and their localized impacts of the HFC phasedown on 
surrounding communities. EPA is also taking comment on whether there 
are other authorities that would allow for the reporting of emissions 
tied to HFC and HFC substitute production. Finally, EPA is seeking 
comment in order to aid our efforts to understand further cumulative 
impacts and how they might be addressed. Since the updated 
environmental justice analysis and proposed reporting requirement are 
focused on chemical stressors, the Agency is requesting additional 
information on how both the chemical and non-chemical stressors 
associated with the HFC phasedown can alter the cumulative impacts 
experienced by communities surrounding HFC production facilities, how 
the Agency can share this information with the public, and whether and 
how the Agency can assess and measure cumulative impacts in the context 
of the HFC phasedown.

XI. Statutory and Executive Order Review

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action is an economically significant regulatory action that 
was submitted to the Office of Management and Budget (OMB) for review. 
Any changes made in response to OMB recommendations have been 
documented in the docket. A summary of the potential costs and benefits 
associated with this action is included in the section titled, ``What 
are the costs and benefits of this proposed action?'' of this proposed 
rulemaking, and EPA prepared an analysis of the potential costs and 
benefits associated with this action, which is available in Docket ID 
No. EPA-HQ-OAR-2022-0430.

B. Paperwork Reduction Act (PRA)

    The information collection activities in this proposed rule have 
been submitted for approval to OMB under the PRA. The ICR document that 
EPA prepared has been assigned EPA ICR number 2685.03 and proposes to 
revise OMB Control No. 2060-0734. You can find a copy of the ICR in the 
docket for this rule (Docket ID. No. EPA-HQ-OAR-2022-0430), and it is 
briefly summarized here.
    Subsection (d)(1)(A) of the AIM Act specifies that on a periodic 
basis, but not less than annually, each person that, within the 
applicable reporting period, produces, imports, exports, destroys, 
transforms, uses as a process agent, or reclaims a regulated substance 
shall submit to EPA a report that describes, as applicable, the 
quantity of the regulated substance that the person: produced, 
imported, and exported; reclaimed; destroyed by a technology approved 
by the Administrator; used and entirely consumed (except for trace 
quantities) in the manufacture of another chemical; or, used as a 
process agent. EPA collects such data regularly to support 
implementation of the AIM Act's HFC

[[Page 66403]]

phasedown provisions. EPA requires quarterly reporting to ensure that 
annual production and consumption limits are not exceeded. It is also 
needed for EPA to be able to review allowance transfer requests, of 
which remaining allowances is a major component of EPA's review. In 
addition, EPA collects information in order to calculate allowances, to 
track the movement of HFCs through commerce, and to require auditing. 
Collecting these data elements allows EPA to ensure that the annual 
quantity of all regulated substances produced or consumed in the United 
States does not exceed the cap established by the AIM Act, consistent 
with subsection (e)(2)(B) of the Act. As described above in this 
preamble, EPA proposes revisions to the recordkeeping and reporting 
requirements and new requirements, including annual reporting of 
estimated emissions from HFC production facilities and recordkeeping of 
analysis results on regulated substances.
    All information sent by the submitter electronically is transmitted 
securely to protect information that is CBI or claimed as CBI 
consistent with the confidentiality determinations made in the 
Framework Rule. The reporting tool guides the user through the process 
of submitting such data. Documents containing information claimed as 
CBI must be submitted in an electronic format, in accordance with the 
recordkeeping requirements.
    For reference, EPA continued to use data collected under the ICR 
for the GHGRP (OMB Control No. 2060-0629) as well as the associated 
reporting tool, the e-GGRT in developing this proposed rulemaking. EPA 
also earlier requested an emergency ICR for a one-time collection 
request pertaining to data necessary to establish the U.S. consumption 
and production baselines as well as to determine potential producers, 
importers, and application-specific end users who were not subject to 
the GHGRP (OMB Control No. 2060-0732). EPA is not revising either ICR 
through this proposed rule.
    Respondents/affected entities: Respondents and affected entities 
will be individuals or entities that produce, import, export, 
transform, distribute, destroy, or reclaim certain HFCs that are 
defined as a regulated substance under the AIM Act. Respondents and 
affected entities will also be individuals and entities who produce, 
import, or export products in six statutorily specified applications: a 
propellant in metered dose inhalers; defense sprays; structural 
composite preformed polyurethane foam for marine and trailer use; the 
etching of semiconductor material or wafers and the cleaning of 
chemical vapor deposition chambers within the semiconductor 
manufacturing sector; mission-critical military end uses, such as 
armored vehicle and shipboard fire suppression systems and systems used 
in deployable and expeditionary applications; and, on board aerospace 
fire suppression.
    Respondent's obligation to respond: Mandatory (AIM Act).
    Estimated number of respondents: 10,195.
    Frequency of response: Quarterly, biannual, annual, and as needed 
depending on the nature of the report.
    Total estimated burden: 57,617 hours (per year). Burden is defined 
at 5 CFR 1320.3(b).
    Total estimated cost: $7,765,111 per year, includes $817,607 
annualized capital or operation & maintenance costs.
    An agency may not conduct or sponsor, and a person is not required 
to respond to, a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations in 40 CFR are listed in 40 CFR part 9.
    Submit your comments on the Agency's need for this information, the 
accuracy of the provided burden estimates and any suggested methods for 
minimizing respondent burden to EPA using the docket identified at the 
beginning of this rule. EPA will respond to any ICR-related comments in 
the final rule. You may also send your ICR-related comments to OMB's 
Office of Information and Regulatory Affairs using the interface at 
www.reginfo.gov/public/do/PRAMain. Find this particular information 
collection by selecting ``Currently under Review--Open for Public 
Comments'' or by using the search function. OMB must receive comments 
no later than January 3, 2023.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities (SISNOSE) under the 
RFA. The small entities subject to the requirements of this action 
include those that may produce, import, export, destroy, use as a 
feedstock or process agent, reclaim, or recycle HFCs. EPA estimates 
that approximately 32 of the 279 potentially affected small businesses 
could incur costs in excess of one percent of annual sales and that 
approximately 28 small businesses could incur costs in excess of three 
percent of annual sales. Because there is not a significant number of 
small businesses that may experience a significant impact, it can be 
presumed that this action will have no SISNOSE. Details of this 
analysis are presented in ``Economic Impact Screening Analysis for 
Phasedown of Hydrofluorocarbons: Allowance Allocation Methodology for 
2024 and Later Years.'' (Docket ID EPA-HQ-OAR-2022-0430).

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in 
UMRA, 2 U.S.C. 1531-1538 and does not significantly or uniquely affect 
small governments. The action imposes no enforceable duty on any state, 
local, or tribal governments.

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the states, on the relationship between 
the national government and the states, or on the distribution of power 
and responsibilities among the various levels of government.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have tribal implications as specified in 
Executive Order 13175. It will not have substantial direct effects on 
tribes on the relationship between the federal government and Indian 
tribes, or on the distribution of power and responsibilities between 
the federal government and Indian tribes, as specified in Executive 
Order 13175. Thus, Executive Order 13175 does not apply to this action. 
EPA periodically updates tribal officials on air regulations through 
the monthly meetings of the National Tribal Air Association and has 
shared information on this rulemaking through this and other fora.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    This action is subject to Executive Order 13045 (62 FR 19885, April 
23, 1997) because it is an economically significant regulatory action 
as defined by Executive Order 12866, and EPA believes that the 
environmental health or safety risk addressed by this action has a 
disproportionate effect on children. Accordingly, EPA has evaluated the 
environmental health and welfare effects of climate change on children.
    GHGs, including HFCs, contribute to climate change. The GHG 
emissions reductions resulting from implementation of this rule would 
further improve children's health. The assessment literature cited in 
EPA's

[[Page 66404]]

2009 and 2016 Endangerment Findings concluded that certain populations 
and life stages, including children, the elderly, and the poor, are 
most vulnerable to climate-related health effects. The assessment 
literature since 2016 strengthens these conclusions by providing more 
detailed findings regarding these groups' vulnerabilities and the 
projected impacts they may experience.
    These assessments describe how children's unique physiological and 
developmental factors contribute to making them particularly vulnerable 
to climate change. Impacts to children are expected from heat waves, 
air pollution, infectious and waterborne illnesses, and mental health 
effects resulting from extreme weather events. In addition, children 
are among those especially susceptible to most allergic diseases, as 
well as health effects associated with heat waves, storms, and floods. 
Additional health concerns may arise in low-income households, 
especially those with children, if climate change reduces food 
availability and increases prices, leading to food insecurity within 
households. More detailed information on the impacts of climate change 
to human health and welfare is provided in section I.C of this 
preamble.

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution, or Use

    This action is not a ``significant energy action'' because it is 
not likely to have a significant adverse effect on the supply, 
distribution, or use of energy. This action applies to certain 
regulated substances and certain applications containing regulated 
substances, none of which are used to supply or distribute energy.

I. National Technology Transfer and Advancement Act (NTTAA) and 
Incorporation by Reference

    This action involves a technical standard. EPA is proposing to 
require laboratory testing be conducted by a laboratory that is 
accredited to ISO 17025 and accordingly is incorporating by reference 
ISO/IEC 17025:2017, ``General requirements for the competence of 
testing and calibration laboratories'', Third Edition, November 2017. 
ISO/IEC 17025:2017 specifies general requirements for competence, 
impartiality, and consistent operation of laboratories. The standard is 
applicable to all organizations performing laboratory activities, 
regardless of the number of personnel. This standard is available for 
purchase from Techstreet at 3025 Boardwalk Drive, Suite 220, Ann Arbor, 
MI 48108; tel.: 855.999.9870; email: [email protected]; website: 
http://www.techstreet.com/, or https://www.techstreet.com/standards/iso-iec-17025-2017?product_id=2000100. The cost of an electronic copy 
of ISO 17025:2017 is approximately $162. The cost of obtaining this 
accreditation standard is not a significant financial burden for 
laboratories. Therefore, EPA concludes that the ISO 17025 standard 
being incorporated by reference is reasonably available.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    EPA believes that it is not feasible to determine whether this 
action has disproportionately high and adverse effects on minority 
populations, low-income populations and/or indigenous peoples, as 
specified in Executive Order 12898 (59 FR 7629, February 16, 1994). 
This rule would continue to reduce emissions of potent GHGs, which as 
noted earlier in section I of this preamble will reduce the effects of 
climate change, including the public health and welfare effects on 
overburdened and underserved communities, including low-income 
communities and communities of color, and/or indigenous peoples. At the 
same time, the Agency recognizes that phasing down the production of 
HFCs may cause significant changes in the location and quantity of 
production of both HFCs and their substitutes, and that these changes 
may in turn affect emissions of HAP at chemical production facilities. 
EPA carefully evaluated available information on HFC production 
facilities and the characteristics of nearby communities to evaluate 
these impacts. In the Framework Rule, EPA also solicited comment on 
whether these changes pose risks to communities with environmental 
justice concerns and what steps, if any, should be taken either under 
the AIM Act or under EPA's other statutory authorities to address any 
concerns that might exist. Based on EPA's analysis, EPA finds evidence 
of environmental justice concerns near HFC production facilities from 
cumulative exposure to existing environmental hazards in these 
communities. Given uncertainties about which and in what quantities HFC 
substitutes will be produced, EPA cannot determine how this rule would 
affect existing disproportionate adverse effects on communities of 
color and low-income people as specified in Executive Order 12898. 
However, the Agency is proposing to require additional reporting on 
emissions from HFC production facilities and is taking comment on its 
revised analysis for this rule. A summary of the Agency's approach for 
considering potential environmental justice concerns as a result of 
this rulemaking can be found in section X of this preamble, and our 
environmental justice analysis can be found in the RIA addendum, 
available in the docket for this rulemaking.

required to submit reports to EPA pursuant to Sec.  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;
    (A) The calendar year of the expended allowances must be for the 
same calendar year in which the ship containing regulated substances 
berthed for sea arrivals, at the border crossing for land arrivals, or 
in which an air arrival first reached its point of terminus in U.S. 
jurisdiction;
    (B) [Reserved]
* * * * *
    (v) In the case of a heel when the precise quantity is unknown or 
has not been measured prior to import, if the importer of record 
expends, at the time of the import, consumption or application-specific 
allowances in a quantity equal to 10 percent of the total potential 
volume of the container in exchange value-weighted equivalent terms for 
the regulated substance contained therein.
    (vi) All imports pursuant to paragraphs (b)(1)(i) or (v) of this 
section must be accompanied by a certificate of analysis.
    (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 Sec.  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 the importer of record possessed and expended 
allowances in accordance with the requirement outlined in (b)(1)(i) or 
(v) or another party who meets the definition of an importer met one of 
the exceptions set forth in (b)(1)(ii) through (iv) of this section.
* * * * *
    (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.

box or other overpack, the exterior packaging must contain legible and 
visible information in at least 20-point font 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 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, reclaiming, recycling for 
fire suppression, or repackaging regulated substances may sell or 
distribute, or offer for sale or distribution, regulated substances 
without first testing a representative sample of the regulated 
substances that they are producing, importing, reclaiming, recycling 
for fire suppression, or repackaging to verify

the relevant Agency official will issue, through a separate 
notification, calendar year production allowances to entities that 
produced a regulated substance in 2021 or 2022, or both 2021 and 2022. 
The allocation of calendar year 2024, 2025, 2026, 2027, and 2028 
production allowances is calculated as follows for each entity:
    (1) Take the average of the three highest annual exchange value-
weighted production amounts that each eligible entity reported to the 
Agency for calendar years 2011 through 2019;
    (2) Sum every entity's average values determined in paragraph 
(b)(1) of this section and determine each entity's percentage of that 
total;
    (3) Determine the amount of general pool production allowances by 
subtracting the quantity of application-specific allowances for that 
year as determined in accordance with Sec.  84.13 from the production 
cap in Sec.  84.7(b)(3);
    (4) Determine individual entities' production allowance quantities

Sec.  84.11  Allocation of calendar-year consumption allowances.

* * * * *
    (b) Starting with the allocation of 2024 calendar years allowances 
the relevant Agency official will issue, through a separate 
notification, calendar year consumption allowances. The allocation of 
calendar year 2024, 2025, 2026, 2027, and 2028 consumption allowances 
is calculated as follows for each entity:
    (1) For new market entrants that were allocated allowances pursuant 
to Sec.  84.15(e)(3), take the allowances allocated for calendar year 
2023 and divide that value by the proportion of calendar year 2023 
consumption allowances received by general pool allowance holders 
pursuant to paragraph (a) of this section relative to their high three 
average calculated pursuant to paragraph (a)(2) of this section;

[[Page 66407]]

    (2) For entities that produced or imported a regulated substance in 
2021 or 2022, or both 2021 and 2022, and have not been allocated 
allowances pursuant to Sec.  84.15(e)(3), the relevant Agency official 
will calculate and issue allowances to a single entity if multiple 
importers are related through shared corporate or common ownership. The 
relevant Agency official will take the average of the three highest 
annual exchange value-weighted consumption amounts, which for entities 
related through shared corporate or common ownership or control would 
be aggregated and averaged at the corporate or common ownership level, 
that each eligible entity reported to the Agency for calendar years 
2011 through 2019;
    (3) If an entity has a value calculated under (b)(1) of this 
section and (b)(2) of this section, take the single higher value;
    (4) Sum every entity's values as determined in (b)(1), (2), and (3) 
of this section and determine each entity's percentage of that total;
    (5) Determine the amount of general pool consumption allowances by 
subtracting the quantity of application-specific allowances for that 
year as determined in accordance with Sec.  84.13 from the consumption 
cap in Sec.  84.7(b)(3);
    (6) Determine individual entities' consumption allowance quantities 
by multiplying each entity's percentage determined in (b)(3) of this 
section by the amount of general pool allowances determined in (b)(4) 
of this section.
