Phasedown of Hydrofluorocarbons: Establishing the Allowance 
Allocation and Trading Program Under the American Innovation and 
Manufacturing Act

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency is proposing to issue 
regulations to implement certain provisions of the American Innovation 
and Manufacturing Act, as enacted on December 27, 2020. This rulemaking 
proposes to: Establish the hydrofluorocarbon production and consumption 
baselines based on historical data; establish the allowance allocation 
program to phase down hydrofluorocarbon production and consumption; 
determine an initial methodology to allocating allowances and allowing 
for the transfer of those allowances; establish provisions for the 
international transfer of allowances; establish requirements to support 
compliance with phasing down hydrofluorocarbon production and 
consumption; establish recordkeeping and reporting requirements; 
release certain data to provide transparency and support implementation 
of the program; and, address certain other elements related to the 
effective implementation of the American Innovation and Manufacturing 
Act. In addition to the proposed provisions, EPA is seeking advance 
input on how the Agency may alter its determination of company-specific 
allocations in later years. EPA is considering these issues, and 
therefore is seeking public input on them, but is not making any 
particular proposal in relation to them, and therefore will not 
finalize any requirements on these topics before issuing a notice of 
proposed rulemaking and requesting public comment.

DATES: Comments on this notice of proposed rulemaking must be received 
on or before July 6, 2021. Under the Paperwork Reduction Act (PRA), 
comments on the information collection provisions are best assured of 
consideration if the Office of Management and Budget (OMB) receives a 
copy of your comments on or before June 18, 2021. The Environmental 
Protection Agency (EPA) will hold a virtual public hearing on June 3, 
2021. The date, time, and other relevant information for the virtual 
public hearing will be available at https://www.epa.gov/climate-hfcs-reduction.

    You may find the following suggestions helpful for preparing your 
comments: Direct your comments to specific sections of this proposed 
rulemaking and note where your comments may apply to future separate 
actions where possible; explain your views as clearly as possible; 
describe any assumptions that you used; provide any technical 
information or data you used that support your views; provide specific 
examples to illustrate your concerns; offer alternatives; and, make 
sure to submit your comments by the comment period deadline. Please 
provide any published studies or raw data supporting your position. 
Multimedia submissions (audio, video, etc.) must be accompanied by a 
written comment. The written comment is considered the official comment 
and should include discussion of all points you wish to make. EPA will 
generally not consider comments or comment contents located outside of 
the primary submission (e.g., on the web, cloud, or other file sharing 
system).
    If you produced, imported, exported, or destroyed 
hydrofluorocarbons (HFCs) and were subject to the regulatory Greenhouse 
Gas Reporting Program (GHGRP) \1\ requirements (under 40 CFR part 98) 
and are seeking to provide EPA with your past HFC activity, you must 
report that data to EPA's electronic Greenhouse Gas Reporting Tool (e-
GGRT) (https://ghgreporting.epa.gov/ghg/login.do). Companies that were 
not subject to the GHGRP may also submit HFC activity through e-GGRT. 
Information on how to report through e-GGRT in general is available at: 
https://ccdsupport.com/confluence, and specific guidance on HFC 
reporting is available at: https://ccdsupport.com/confluence/display/help/e-GGRT+and+HFC+Data+Reporting+related+to+AIM. EPA requests that 
any company that reports on HFC activity to the GHGRP in response to 
the requests in this proposed rule also submit a comment to the docket 
noting the date that the company submitted the information to e-GGRT so 
that EPA can more easily track such submissions.

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 are its main areas of focus?

    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 (Pub. L. 116-260).\2\ The AIM Act directs EPA 
to address HFCs by providing new authorities in three main areas: To 
phase down the production and consumption of listed HFCs, manage these 
HFCs and their substitutes, and facilitate the transition to next-
generation technologies by restricting use of these HFCs in the sector 
or subsectors in which they are used. This rulemaking focuses on the 
first area--the phasedown of the production and consumption of HFCs. 
EPA anticipates that there will be future rulemakings including those 
related to the latter two main areas, and therefore EPA is only 
accepting comment on the first area in this proposed rulemaking.
---------------------------------------------------------------------------

    \2\ EPA is proposing to interpret the phrase ``under this 
section'' in the AIM Act to refer to section 103 of the Consolidated 
Appropriations Act, 2021, and thus to mean ``under the AIM Act.'' 
This approach would be consistent with the language included in the 
Act, such as subsection (a) which states that ``[t]his section may 
be cited as American Innovation and Manufacturing Act of 2020.''
---------------------------------------------------------------------------

    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. The Act uses the term ``produce'' to 
mean ``the manufacture \3\ of a regulated substance from a raw material 
or feedstock chemical,'' but excludes from the definition destruction 
of HFCs using approved technologies; reclamation, reuse, or recycling 
of HFCs; and HFCs for transformation.\4\ The Act uses the term 
``consumption'' to refer to the amount of HFCs produced in and imported 
to the United States, subtracting the amount exported.
---------------------------------------------------------------------------

    \3\ While the AIM Act and the proposed definition in this rule 
use the term ``manufacture'' in defining the term ``produce,'' in 
implementing EPA's CAA Title VI programs the agency has historically 
used the term ``production'' when referring to the manufacture of 
chemicals and ``manufacture'' when referring to the manufacture of 
equipment. EPA intends to continue using this framing when 
describing production of chemicals and manufacture of equipment 
under the AIM Act to help distinguish between the two activities.
    \4\ The AIM Act uses the phrase ``a regulated substance that is 
used and entirely consumed (except for trace quantities) in the 
manufacture of another chemical'' instead of ``transformation'' in 
this definition. The quoted phrase is the definition used in Part 82 
for the term ``transform.'' The AIM Act subsequently uses the terms 
``transformation'' and ``use as a feedstock'' interchangeably. These 
two terms are intended to have the same meaning and are also used 
interchangeably in this proposal.
---------------------------------------------------------------------------

    The 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'' 5 6 to each regulated 
substance (along with other chemicals that are used to calculate the 
baseline). The table in subsection (c)(1), reproduced here in Table 2, 
lists the 18 regulated substances and their exchange values.
---------------------------------------------------------------------------

    \5\ 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 IPCC (2007). EPA uses the terms 
``global warming potential'' and ``exchange value'' interchangeably 
in this proposal.

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

The AIM Act requires that the EPA Administrator ensure the annual 
quantity of all regulated substances produced or consumed \7\ in the 
United States does not exceed the applicable percentage listed for the 
production or consumption baseline.
---------------------------------------------------------------------------

    \7\ 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.
---------------------------------------------------------------------------

    In order to execute this statutory directive, EPA must determine 
both a production and consumption baseline from which the yearly 
targets are calculated. The AIM Act provides formulas for how to set a 
baseline. The equations are composed of an HFC component, a 
hydrochlorofluorocarbon (HCFC) component, and a chlorofluorocarbon 
(CFC) component. Specifically, EPA is directed to calculate the 
production baseline by adding: (i) The average annual quantity of all 
regulated substances produced in the United States from January 1, 
2011, through December 31, 2013, and (ii) 15 percent of the production 
level of HCFCs in calendar year 1989, and (iii) 0.42 percent of the 
production level of CFCs in calendar year 1989.
    EPA is directed to calculate the consumption baseline by adding: 
(i) The average annual quantity of all regulated substances consumed in 
the United States from January 1, 2011, through December 31, 2013, and 
(ii) 15 percent of the consumption level of HCFCs in calendar year 
1989, and (iii) 0.42 percent of the consumption level of CFCs in 
calendar year 1989. 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 within 270 days of the Act's enactment 
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)(D) directs EPA to ``determine the 
quantity of allowances for the production and consumption of regulated 
substances that may be used for the following calendar year'' by 
October 1 each year. Subsection (e)(2) of the Act has a general 
prohibition that no person \8\ shall produce or consume a quantity of 
regulated substances in the United States without a corresponding 
quantity of allowances. Also within 270 days, EPA is directed in 
subsection (g) to establish regulations governing the transfer of 
production and consumption of allowances. Subsection (e)(2)(A) also 
provides that no person shall hold, use, or transfer an allocated 
production or consumption allowance except in accordance with the 
transfer regulations. Under subsection (g), the transfer regulations 
are to use the applicable exchange values and ``ensure that the 
transfers . . . will result in greater total reductions'' in production 
and consumption ``than would occur during the year in the absence of 
the transfers.''
---------------------------------------------------------------------------

    \8\ 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 requirements and prohibitions.
---------------------------------------------------------------------------

    Subsection (e)(4)(B)(iv) of the Act requires EPA to allocate 
allowances sufficient to meet the full quantity needed for production 
and consumption for six specific applications for five years following 
enactment. EPA is to determine the necessary allowance amount for these 
applications ``based on projected, current, and historical trends.'' 
The six statutorily listed applications are: Propellants in metered-
dose inhalers; defense sprays (e.g., bear spray); structural composite 
preformed polyurethane foam for marine use and trailer use; etching of 
semiconductor material or wafers and the cleaning of chemical vapor 
deposition (CVD) chambers within the semiconductor manufacturing 
sector; mission-critical military end uses; and on board aerospace fire 
suppression. The allowances EPA allocates for these applications are 
for the ``exclusive use'' in one of the six applications.
    Subsection (j) of the AIM Act speaks to international cooperation. 
Of particular relevance to this rulemaking, subsection (j)(4) requires 
EPA to promulgate a rule by December 27, 2021, to carry out the 
subsection. The AIM Act outlines several restrictions and requirements 
governing international transfers of production allowances in 
subsections (j)(1) and (j)(2) and also provides some discretionary 
authority to EPA in (j)(3) regarding the effect of such transfers on 
production limits.
    In subsection (k)(1)(A), the AIM Act provides EPA with the 
authority to promulgate necessary regulations to carry out EPA's 
functions under the Act, including its obligations to ensure that the 
Act's requirements are satisfied. The Act also states that Clean Air 
Act (CAA) sections 113, 114, 304, and 307 apply to the AIM Act and any 
regulations EPA promulgates under the AIM Act as though the AIM Act 
were part of Title VI of the CAA. Accordingly, this rulemaking is 
subject to CAA section 307(d) (42 U.S.C. 7607(d)(1)(I)) (CAA section 
307(d) applies to ``promulgation or revision of regulations under 
subchapter VI of this chapter (relating to stratosphere and ozone 
protection)'').
    In addition, although there is limited legislative history 
available on the AIM Act, Congress is generally presumed to legislate 
with an awareness of the existing law that is pertinent to enacted 
legislation. Given the similarities in the text, structure, and 
function of the production and consumption phasedown provisions of the 
AIM Act and EPA's program phasing out ozone-depleting substances (ODS) 
under Title VI of the CAA,\9\ EPA finds it reasonable to build on its 
experience phasing out ODS when developing the AIM Act's HFC allowance 
allocation and trading program, while also recognizing that there are 
areas where the AIM Act's requirements diverge from the text and 
framework of Title VI of the CAA. For example, EPA uses the 
recordkeeping and reporting provisions that the Agency has refined over 
time in the ODS context as the starting point for the proposed 
recordkeeping and reporting requirements in this rule. There are many 
instances where the definitions and structure are either identical or 
have only slight differences. For example, the definitions of 
``import'' in the AIM Act and section 601 of the CAA are materially 
similar though they have slightly different phrasing. In at least some 
instances, Congress adopted language in the AIM Act that matches EPA's 
implementation approach for

[[Page 27155]]

ODS production and consumption controls under CAA Title VI as reflected 
in 40 CFR part 82, subpart A. For example, the definition for 
``produce'' in the AIM Act mirrors the parallel definition in CAA 
section 601 in many respects, but in contrast to the CAA definition, 
the AIM Act explicitly excludes the destruction of regulated substances 
using technologies approved by the Administrator from being counted in 
production. While the CAA definition does not explicitly exclude 
destruction from production, EPA's regulatory definition for 
``production'' in 40 CFR 82.3 does exclude destruction from being 
counted as production. Throughout this proposed rulemaking, EPA 
explains how the Agency is relying on and building from its experience 
implementing the ODS phaseout provisions in the CAA and its 
implementing regulations where such considerations are relevant to 
creating the framework structure for the AIM Act's required HFC 
allowance allocation and trading program. Given EPA's extensive 
experience phasing out ODS under similar CAA authority for a regulated 
community that bears marked resemblance to entities that could be 
impacted by the rulemaking, reliance on EPA's expertise will help 
achieve the goals outlined by Congress in implementing the AIM Act.
---------------------------------------------------------------------------

    \9\ EPA's well-established regulatory program at 40 CFR part 82, 
subpart A, provides for the allocation of ODS production and 
consumption allowances, implementing the ODS production and 
consumption controls of Title VI of the CAA and facilitating an 
orderly phaseout.
---------------------------------------------------------------------------

C. What are HFCs?

    HFCs are intentionally produced \10\ fluorinated chemicals that 
have no known natural sources. HFCs are used in the same applications 
that ODS have historically been used in, such as refrigeration and air 
conditioning, foam blowing agents, solvents, aerosols, and fire 
suppression. HFCs are potent greenhouse gases (GHGs) with 100-year 
global warming potentials (GWPs) (a measure of the relative climatic 
impact of a GHG) that can be hundreds to thousands of times more potent 
than carbon dioxide (CO2).
---------------------------------------------------------------------------

    \10\ 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 
HCFC-22.
---------------------------------------------------------------------------

    Although HFCs represent a small fraction (~1.5 percent) of the 
current total GWP-weighted amount of GHG emissions,\11\ their use is 
growing worldwide due to the global phaseout of 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, but global 
adherence to the Kigali Amendment to the Montreal Protocol (Kigali 
Amendment) would substantially reduce future emissions, leading to a 
peaking of HFC emissions before 2040.\12\

Assessment of Ozone Depletion: 2018, World Meteorological 
Organization, Global Ozone Research and Monitoring Project--Report

    \12\ Ibid
---------------------------------------------------------------------------

    Atmospheric observations of most currently measured HFCs confirm 
their amounts are increasing in the global atmosphere 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.\13\
---------------------------------------------------------------------------

    \13\ Ibid.
---------------------------------------------------------------------------

    In 2016, HFCs accounted for a radiative forcing of 0.025 W/m\2\, 
not including additional forcing from HFC-23 of 0.005 W/m\2\: this is a 
36 percent increase in total HFC forcing relative to 2012. This 
radiative forcing was projected to increase an order of magnitude to 
0.25 W/m\2\ by 2050, not including additional forcing from HFC-23. In 
2016, in Kigali, Rwanda, countries agreed to adopt an amendment to the 
Montreal Protocol, known as the Kigali Amendment, which outlines a 
global phasedown of the production and consumption of HFCs. If the 
Kigali Amendment were to be fully implemented, it is expected to reduce 
the future radiative forcing due to HFCs (excluding HFC-23) to 0.13 W/
m\2\ in 2050, a reduction of about 50 percent compared to the radiative 
forcing projected in the baseline scenario of uncontrolled HFCs.\14\
---------------------------------------------------------------------------

    \14\ Ibid.
---------------------------------------------------------------------------

    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 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 (~75 percent of total HFC use in 2018) and in air 
conditioning in vehicles and refrigerated transport (~8 percent). 
Smaller amounts are used in foam products (~11 percent), aerosols (~4 
percent), fire protection systems (~1 percent) and solvents (~1 
percent).\15\
---------------------------------------------------------------------------

    \15\ Calculations based on EPA's Vintaging Model, which 
estimates the annual chemical emissions from industry sectors that 
historically used ODS, including refrigeration and air-conditioning, 
foam blowing agents, solvents, aerosols, and fire suppression. The 
model uses information on the market size and growth for each end 
use, as well as a history and projections of the market transition 
from ODS to alternatives. The model tracks emissions of annual 
``vintages'' of new equipment that enter into operation by 
incorporating information on estimates of the quantity of equipment 
or products sold, serviced, and retired or converted each year, and 
the quantity of the compound required to manufacture, charge, and/or 
maintain the equipment. Additional information on these estimates is 
available in U.S. EPA, April 2016. EPA Report EPA-430-R-16-002.

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

    EPA considered the emissions reductions from an HFC phasedown in 
the United States and presented the results in the 2016 Biennial Report 
to the United Nations Framework Climate Change Convention (UNFCCC).\16\ 
At the time, EPA provided a reductions estimate of 113 million metric 
tons of carbon dioxide equivalent (MMTCO2e) of reduced U.S. 
HFC emissions associated with the implementation of an amendment 
proposal submitted in 2015 by the United States, Canada, and Mexico 
that was under consideration by the parties to the Montreal Protocol 
and was very similar to the Kigali Amendment. While the Kigali 
Amendment ultimately adopted under the Montreal Protocol has certain 
marked differences from the AIM Act, given the two documents have a 
nearly identical list of HFCs to be phased down following the same 
schedule, the 2016 Biennial Report provides useful information. The 
Biennial Report included estimates for HFC actions under CAA section 
612 modeled in the 2016 Current Measures. HFC emissions reductions 
through additional measures in 2020 and 2025 relative to the 2016 
Current Measures scenario were presented under the Additional Measures 
scenario and included both options for continued action under the CAA 
and the implementation of an HFC phasedown in the United States, which 
is similar to the requirements of the AIM Act with an earlier start 
date.\17\ The

[[Page 27156]]

emissions reductions for the Additional Measures were estimated to be 
63 MMTCO2e in 2020 and 113 MMTCO2e in 2025.

    \17\ The ``Current Measures'' scenario in the Biennial Report 
included HFC reductions estimated under a final rule EPA issued on 
July 20, 2015, which, among, other things, changed listings for 
certain HFCs and blends from acceptable to unacceptable in various 
end uses in the aerosols, refrigeration and air conditioning, and 
foam blowing sectors. The ``Additional Measures'' scenario in the 
Biennial Report included additional actions, some of which were 
included in a final rule EPA issued on December 1, 2016, that EPA 
anticipated under a proposed amendment to the Montreal Protocol to 
phase down HFC production and consumption. Since the 2016 Biennial 
Report, after a challenge to the 2015 rule, the U.S. Court of 
Appeals for the D.C. Circuit (``the court'') issued a partial 
vacatur of the 2015 rule ``to the extent it requires manufacturers 
to replace HFCs with a substitute substance,'' and remanded the rule 
to EPA for further proceedings. Later, the court issued a similar 
decision on portions of the final rule issued December 1, 2016. See

D. How do HFCs affect public health and welfare?

    Elevated concentrations of GHGs including HFCs have been warming 
the planet, leading to changes in the Earth's climate including changes 
in the frequency and intensity of heat waves, precipitation, and 
extreme weather events, rising seas, and retreating snow and ice. The 
changes taking place in the atmosphere as a result of the well-
documented buildup of GHGs due to human activities are changing the 
climate at a pace and in a way that threatens human health, society, 
and the natural environment. While EPA does not need to make any 
particular scientific or factual findings in order to regulate HFCs 
under the AIM Act's phasedown provisions, in this section, EPA is 
providing some scientific background on climate change to offer 
additional context for this rulemaking and to help the public 
understand the environmental impacts of GHGs such as HFCs.
    Extensive additional information on climate change is available in 
the scientific assessments and the EPA documents that are briefly 
described in this section, as well as in the technical and scientific 
information supporting them. One of those documents is EPA's 2009 
Endangerment and Cause or Contribute Findings for Greenhouse Gases 
Under Section 202(a) of the CAA (74 FR 66496, December 15, 2009).\18\ 
In the 2009 Endangerment Finding, the Administrator found under section 
202(a) of the CAA that elevated atmospheric concentrations of six key 
well-mixed GHGs--CO2, methane (CH4), nitrous 
oxide (N2O), HFCs, perfluorocarbons (PFCs), and sulfur 
hexafluoride (SF6)--``may reasonably be anticipated to 
endanger the public health and welfare of current and future 
generations'' (74 FR 66523). The 2009 Endangerment Finding, together 
with the extensive scientific and technical evidence in the supporting 
record, documented that climate change caused by human emissions of 
GHGs (including HFCs) threatens the public health of the U.S. 
population. It explained that by raising average temperatures, climate 
change increases the likelihood of heat waves, which are associated 
with increased deaths and illnesses (74 FR 66497). While climate change 
also increases the likelihood of reductions in cold-related mortality, 
evidence indicates that the increases in heat mortality will be larger 
than the decreases in cold mortality in the United States (74 FR 
66525). The 2009 Endangerment Finding further explained that compared 
with a future without climate change, climate change is expected to 
increase tropospheric ozone pollution over broad areas of the United 
States, including in the largest metropolitan areas with the worst 
tropospheric ozone problems, and thereby increase the risk of adverse 
effects on public health (74 FR 66525). Climate change is also expected 
to cause more intense hurricanes and more frequent and intense storms 
of other types and heavy precipitation, with impacts on other areas of 
public health, such as the potential for increased deaths, injuries, 
infectious and waterborne diseases, and stress-related disorders (74 FR 
66525). Children, the elderly, and the poor are among the most 
vulnerable to these climate-related health effects (74 FR 66498).
---------------------------------------------------------------------------

    \18\ In describing these 2009 Findings in this proposal, EPA is 
neither reopening nor revisiting them.
---------------------------------------------------------------------------

    The 2009 Endangerment Finding also documented, together with the 
extensive scientific and technical evidence in the supporting record, 
that climate change touches nearly every aspect of public welfare \19\ 
in the United States with resulting economic costs, including: Changes 
in water supply and quality due to changes in drought and extreme 
rainfall events; increased risk of storm surge and flooding in coastal 
areas and land loss due to inundation; increases in peak electricity 
demand and risks to electricity infrastructure; and the potential for 
significant agricultural disruptions and crop failures (though offset 
to some extent by carbon fertilization). These impacts are also global 
and may exacerbate problems outside the United States that raise 
humanitarian, trade, and national security issues for the United States 
(74 FR 66530).
---------------------------------------------------------------------------

    \19\ The CAA states in section 302(h) that ``[a]ll language 
referring to effects on welfare includes, but is not limited to, 
effects on soils, water, crops, vegetation, manmade materials, 
animals, wildlife, weather, visibility, and climate, damage to and 
deterioration of property, and hazards to transportation, as well as 
effects on economic values and on personal comfort and well-being, 
whether caused by transformation, conversion, or combination with 
other air pollutants.'' 42 U.S.C. 7602(h).
---------------------------------------------------------------------------

    In 2016, the Administrator similarly issued Endangerment and Cause 
or Contribute Findings for greenhouse gas emissions from aircraft under 
section 231(a)(2)(A) of the CAA (81 FR 54422).\20\ In the 2016 
Endangerment Finding, the Administrator found that the body of 
scientific evidence amassed in the record for the 2009 Endangerment 
Finding compellingly supported a similar endangerment finding under CAA 
section 231(a)(2)(A), and also found that the science assessments 
released between the 2009 and the 2016 Findings ``strengthen and 
further support the judgment that GHGs in the atmosphere may reasonably 
be anticipated to endanger the public health and welfare of current and 
future generations'' (81 FR 54424).
---------------------------------------------------------------------------

    \20\ In describing these 2016 Findings in this proposal, EPA is 
neither reopening nor revisiting them.
---------------------------------------------------------------------------

    Since the 2016 Endangerment Finding, the climate has continued to 
change, with new records being set for several climate indicators such 
as global average surface temperatures, greenhouse gas concentrations, 
and sea level rise. Additionally, major scientific assessments continue 
to be released that further improve our understanding of the climate 
system and the impacts that GHGs have on public health and welfare both 
for current and future generations. These updated observations and 
projections document the rapid rate of current and future climate 
change both globally and in the United States.21 22 23 24

II. What is the summary of this proposed action?

    In this rulemaking, EPA is proposing to: Establish the HFC 
production and consumption baselines based on historical data; 
establish the allowance allocation program to phase down HFC production 
and consumption; determine an initial approach to allocating calendar-
year allowances and allowing for the transfer of those allowances; 
establish provisions for the international transfer of allowances; 
establish recordkeeping and reporting requirements; release certain 
data to provide transparency and support implementation of the program; 
and, address certain other elements related to the effective 
implementation of the AIM Act.
    The AIM Act directs EPA to issue a final rule by September 23, 
2021, to provide for the phasedown of the production and consumption of 
HFCs through an allowance allocation and trading program. This 
rulemaking, when finalized, is intended to fulfill that statutory 
directive. Additionally, 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. Thus, by 
October 1, 2021, EPA must calculate and determine the quantity of 
production and consumption allowances for 2022. EPA intends to issue 
allowances for the 2022 calendar year no later than October 1, 2021, 
using the procedure established through this rulemaking. EPA proposes 
that this be a single year allocation and intends to issue individual 
allowances for the 2023 calendar year no later than October 1, 2022, 
using the procedure established through this rulemaking. The AIM Act 
further directs EPA to promulgate by September 23, 2021, a regulation 
governing the transfer of production and consumption allowances, and 
EPA is herein proposing regulatory requirements related to this 
statutory directive. The AIM Act also directs EPA to issue by December 
27, 2021, regulations related to the international transfer of 
production allowances. EPA is herein proposing regulatory requirements 
related to this statutory directive as well.
    EPA is proposing to establish a regulatory framework under the 
statutory timelines required by the AIM Act, but also acknowledges at 
the outset that we intend to revisit how to allocate allowances for 
2024 and beyond and further build out aspects of the program. To 
accurately reflect that intention in this rule, EPA is proposing that 
the initial approach for determining allowance allocations that EPA 
would establish in this framework rule be time-limited. This would 
necessitate completion of another notice-and-comment rulemaking prior 
to October 1, 2023, to issue allowances for calendar year 2024 and 
later years. As a result, section XI of this preamble, which includes 
an ANPRM, explains ideas the Agency is considering for a separate 
future rulemaking that will address the criteria/framework for issuing 
allowances for 2024 and later years. Given high baseline health risks 
related to air toxics in communities near facilities that produce HFCs, 
EPA is seeking input in sections III and XI (the ANPRM) on whether 
there are potential environmental justice concerns that could be 
affected by the phasedown of HFCs, allowance transfers, and/or the 
production of substitutes. EPA is also seeking input on ways to ensure 
that these elevated risks not be further exacerbated by changes in the 
use patterns for production of HFCs or their substitutes. The Agency is 
soliciting comments on the concepts introduced in the ANPRM but is not 
proposing any action associated with those elements in this rulemaking. 
Instead, any comments received on elements of the ANPRM will 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.
    EPA estimates that in 2022 the annual net benefits are $2.6 
billion, reflecting compliance costs of $200 million and social 
benefits of $2.8 billion. In 2036, when the final phasedown step is 
reached at 15 percent of the statutorily defined HFC baseline, the 
estimated annual net benefits are $17.9 billion. The present value of 
cumulative net benefits evaluated from 2022 through 2050 is $283.9 
billion at a three percent discount rate or $278.6 billion at a seven 
percent discount rate.\25\ The present value of net benefits are 
calculated over the 29-year period from 2022-2050 to account for the 
years that emissions will be reduced following the consumption 
reductions from 2022-2036. Over the 15-year period of the phasedown of 
HFCs, at a three percent discount rate the present value of cumulative 
compliance costs are negative $5 billion, or $5 billion in savings, the 
present value of cumulative social benefits is $103.6 billion, and the 
present value of cumulative net benefits is $108.2 billion. Evaluated 
at a seven percent discount rate, the present value of cumulative 
compliance costs are negative $3 billion, or $3 billion in savings, and 
the present value of cumulative net benefits is $106.6 billion. Climate 
benefits are based on changes (reductions) in HFC emissions and are 
calculated using four different estimates of the social cost of HFCs 
(SC-HFCs) (model average at 2.5 percent, 3 percent, and 5 percent 
discount rates; and 95th percentile at 3 percent discount rate). The 
benefits presented in this paragraph are the benefits associated with 
the average SC-HFC at a 3 percent discount rate, but the Agency does 
not have a single central SC-HFC point estimate. The Interagency 
Working Group on the Social Cost of Greenhouse Gases (IWG) emphasized 
the importance and value of considering the benefits calculated using 
all four estimates.
---------------------------------------------------------------------------

    \25\ All values for costs and benefits in this section are given 
in 2020 dollars and are calculated by discounting future costs and 
benefits to 2022 using a three percent discount rate. Calculations 
using other discount rates and discussion of the impact of the 
discount rate are found in the Regulatory Impact Analysis.
---------------------------------------------------------------------------

    As summarized further in section X of the preamble and described 
more fully in the Regulatory Impact Analysis (RIA) for this proposed 
rulemaking, EPA's analysis indicates the principal costs (or savings) 
result from industry transitioning to substitute chemicals and 
technology. The principal benefits result from a decrease in emissions 
of HFCs into the atmosphere and the corresponding effects on global 
warming. The benefits are monetized by using the Social Cost of HFCs 
(SC-HFCs). SC-HFCs is estimated using a method consistent with the 
method used to estimate the Social Cost of Greenhouse Gases (SC-GHGs). 
An alternative method was also considered which estimates SC-HFCs by 
using the GWP (or exchange value) of HFCs and scaling to the known 
social cost of another GHG, e.g., CO2, CH4, or 
N2O.

III. How is EPA considering environmental justice?

    Executive Order 12898 (59 FR 7629; February 16, 1994) and Executive 
Order 14008 (86 FR 7619; January 27, 2021) establish federal executive 
policy on

[[Page 27158]]

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 minority populations 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, regulations, and 
policies.\26\ 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.\27\ 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.\28\

EPA's May 2015 guidance document
    ``Guidance on Considering Environmental Justice During the 
Development of an Action.'' Epa.gov, Environmental Protection 
Agency, 17 Feb. 2017, www.epa.gov/environmentaljustice/guidance-considering-environmental-justice-during-development-action.
    \28\ The definitions and criteria for ``disproportionate 
impacts,'' ``difference,'' and ``differential'' are contained in 
EPA's June 2016 guidance document ``Technical Guidance for Assessing 
Environmental Justice in Regulatory Analysis.'' Epa.gov, 
Environmental Protection Agency, https://www.epa.gov/sites/production/files/2016-06/documents/ejtg_5_6_16_v5.1.pdf.
---------------------------------------------------------------------------

    A regulatory action may involve potential environmental justice 
concerns if it could: (1) Create new disproportionate impacts on 
minority populations, low-income populations, and/or indigenous 
peoples; (2) exacerbate existing disproportionate impacts on minority 
populations, low-income populations, and/or indigenous peoples; or (3) 
present opportunities to address existing disproportionate impacts on 
minority populations, 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.
    As described elsewhere in this notice, this rule proposes to 
establish the framework for, and begin, the United States' phasedown of 
HFCs, which is projected to achieve significant benefits by reducing 
production and consumption of certain chemicals with high GWPs. Section 
I.D. of this proposal briefly summarizes the public health and welfare 
effects of GHG emissions (including HFCs) as documented in EPA's 2009 
and 2016 Endangerment Findings. As part of these Endangerment Findings, 
the Administrator considered climate change risks to minority 
populations and low-income populations, finding that certain parts of 
the population may be especially vulnerable 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.
    More recent assessment reports by the U.S. Global Change Research 
Program (USGCRP), the Intergovernmental Panel on Climate Change (IPCC), 
and the National Research Council (NRC) of the National Academies 
demonstrate that the potential impacts of climate change raise 
environmental justice issues. These reports concluded that poorer 
communities can be especially vulnerable to climate change impacts 
because they tend to have more limited adaptive capacities 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. Native American tribal communities 
possess unique vulnerabilities to climate change, particularly those 
impacted by degradation of natural and cultural resources within 
established reservation boundaries and threats to traditional 
subsistence lifestyles. Tribal communities whose health, economic well-
being, and cultural traditions that depend upon the natural environment 
will likely be affected by the degradation of ecosystem goods and 
services associated with climate change. The Technical Support Document 
for the 2009 Endangerment Finding also specifically noted that 
Southwest native cultures are especially vulnerable to water quality 
and availability impacts, and Native Alaskan communities are already 
experiencing disruptive impacts, including coastal erosion and shifts 
in the range or abundance of wild species crucial to their livelihoods 
and well-being.
    As alluded to elsewhere in this proposal, and detailed in the RIA, 
which can be found in the docket for this rulemaking, the provisions in 
this proposed rulemaking as part of the phasedown of HFCs in the United 
States

[[Page 27159]]

would, if finalized, achieve significant benefits associated with 
reducing climate change. However, as described in the RIA and 
summarized below, there is 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. EPA is soliciting comment 
and/or data or other information in section XI that could help reduce 
the potential for inadvertent or unexpected distributional effects from 
this program, including the potential for environmental justice 
concerns due to the release of toxic chemicals that are feedstocks, 
catalysts, or byproducts in the production of HFCs or HFC substitutes.
    More specifically, EPA is seeking comment on whether changes in 
emissions, particularly in communities that are already 
disproportionately affected by air pollution, could occur as the result 
of the HFC phasedown, the associated ability to transfer allowances, or 
other unrelated changes in the market. EPA also seeks comment on 
whether there are remedies that could be applied as part of the design 
of the program in the event the Agency determines such unintended 
distributional impacts exist. In addition, EPA solicits comment on 
whether other regulatory authorities would be more appropriate to 
address any inadvertent or unexpected distributional effects that are 
identified, for example, if a producer obtained allowances in 
sufficient quantities to grow HFC production, which could potentially 
increase air emissions at that location. In such instances, where other 
authorities may be a more appropriate avenue, EPA expects that effects 
would be addressed through that avenue outside of AIM Act regulatory 
processes under timelines appropriate to those other programs.
    EPA intends to develop another rule before allowances are allocated 
for calendar year 2024 that may alter the framework and procedure for 
issuing allowance allocations and could possibly address any identified 
environmental justice concerns past the year 2023. The HFC phasedown 
schedule prescribed by Congress may also reduce the potential for a 
facility to increase emissions above current levels for a prolonged 
period. EPA notes that this rule affects a small number of entities 
through a distinct allocation program, and that these entities 
manufacture a wide variety of products and are subject to a number of 
distinct market and regulatory forces independent of this HFC program. 
As such, the issues identified here and possible remedies may not be 
broadly applicable or practicable in other rulemakings.
    A reasonable starting point for assessing the need for a more 
detailed environmental justice analysis is to review 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 USGCRP, IPCC, and NRC. It is 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 and regulatory options. Where applicable and 
practicable, the Agency's Regulatory Impact Analysis, available in the 
docket for this rulemaking, examines certain metrics for an 
environmental justice analysis comprising more than just climate change 
effects, including: The proximity of companies receiving allowances to 
minority populations, low-income populations, and/or indigenous 
peoples; the number of companies receiving allowances that may be 
impacting population groups of concern; the nature, amounts, and 
location of regulated HFC production that may impact 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 and is based on public data from the Toxics 
Release Inventory (TRI), GHGRP, EJSCREEN (an environmental justice 
mapping and screening tool developed by EPA), Enforcement and 
Compliance History Online (ECHO), and Census data. The analysis of 
potential environmental justice concerns focuses mainly on 
characterizing baseline emissions of air toxics that are also 
associated with chemical feedstock use for HFC production. As noted in 
the RIA, 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 relatively small number of 
facilities affected by the proposed rule has enabled EPA to assemble a 
uniquely granular assessment of the characteristics of these facilities 
and the communities where they are located.
    Overall, this rule would reduce GHG emissions, which would benefit 
populations that may be especially vulnerable to damages associated 
with climate change. However, 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. The 
environmental justice analysis, which examines racial and economic 
demographic and health risk information, finds heterogeneity in 
community characteristics around individual facilities. The analysis 
shows that the total baseline cancer risk and total respiratory risk 
from air toxics (not all of which stem from HFC production) varies, but 
is generally higher, and in some cases much higher, within one to three 
miles of a HFC production facility. The analysis also finds that higher 
percentages of low income and Black or African American individuals 
live near several HFC production facilities compared with the 
appropriate national and state level average. It is not clear the 
extent to which these baseline risks are directly related to HFC 
production, but some HFC production feedstocks, catalysts, and 
byproducts are toxic, particularly with respect to potential 
carcinogenicity (e.g., carbon tetrachloride, tetrachloroethylene, 
trichloroethylene, etc.). Additionally, some HFC alternatives, e.g., 
HFOs, use the same chemicals as feedstocks in their production or 
released as byproducts, potentially raising concerns about local 
exposure to them. However, given limited information regarding where 
substitutes will be produced and what other factors might affect 
production and emissions at those locations, it is unclear to what 
extent this proposed rule would affect baseline risks from hazardous 
air toxics for communities living near HFC production facilities. EPA 
requests commenters provide data or other information to help better 
characterize these changes and their implications for

[[Page 27160]]

nearby communities for analysis of the final rule.
    As discussed, EPA's preliminary analysis of potential environmental 
justice concerns is contained in the RIA, which is available in the 
docket, as well as information on non-production releases (as defined 
by TRI), water releases, and off-site disposal for chemicals used in 
HFC production. EPA seeks input on the environmental justice analysis 
contained in the RIA, 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 (i.e., 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 is also seeking comment on whether 
there are other regulatory tools better suited than adjustments to the 
HFC program design to address potential increases in emissions in non-
HFC feedstocks and byproducts observed at facilities subject to the 
Congressionally mandated phasedown of HFCs under the AIM Act, if any. 
EPA is also soliciting comment on key assumptions underlying the 
environmental justice analysis. In addition to the questions asked in 
this section III, EPA is also soliciting input in section XI on what 
mechanisms the Agency could consider to prevent or mitigate any 
increase in exposure to air toxics emissions from facilities located 
near high risk communities, including from the proposed provisions 
relating to transfer of allowances. EPA invites readers to refer to 
section XI for that discussion.

IV. What definitions are proposed to implement the AIM Act?

    EPA is proposing to establish definitions that would implement the 
framework for the AIM Act generally and the allowance allocation and 
trading program specifically. Where possible, EPA is proposing to adopt 
definitions as written in 40 CFR part 82, subpart A, with modifications 
if needed to conform to differences in the AIM Act.

A. What definitions is EPA proposing to adopt from 40 CFR 82.3 without 
substantive change?

    EPA is proposing to adopt definitions for the following defined 
terms as used in 40 CFR 82.3 with only those changes that are needed to 
conform with the AIM Act. These defined terms are used in the same or 
substantially similar manner as in the ODS phaseout under the CAA. In 
many instances, the only proposed change to the definition of a term is 
to replace ``controlled substances'' with ``regulated substances,'' as 
the latter is the term used to describe HFCs in the AIM Act. In other 
instances, EPA is not including citations to 40 CFR part 82, subpart A, 
that were found in those definitions but that are not directly relevant 
for implementing the AIM Act. Because there is significant overlap 
between the regulated community of the AIM Act and those who partook in 
the ODS phaseout under Title VI of the CAA, maintaining the same 
definitions, where consistent with AIM Act requirements, would provide 
certainty to those that have been using and are familiar with these 
terms from the ODS phaseout experience. EPA welcomes comment on whether 
any of these terms should be updated or modified.
    These terms are: Administrator, Central Data Exchange, Consumption, 
Consumption allowances, Export, Exporter, Foreign country, Heel, 
Importer, Individual shipment, Non-objection notice, Person, Production 
allowances, Source facility, Transform, Transhipment, and Used 
regulated substances.

B. What definitions is EPA proposing to adopt from 40 CFR 82.3 with 
substantive change?

    EPA is proposing to adopt the definitions for the following defined 
terms as written in 40 CFR 82.3 with some changes necessary to align 
the definition with the AIM Act beyond those described in the previous 
section. The terms are: Confer, Destruction, Facility, Import, Metered 
Dose Inhaler (MDI), and Reclaim.
    Destruction. EPA is proposing to define destruction as ``the 
expiration of a regulated substance to the destruction and removal 
efficiency actually achieved. Such destruction might result in a 
commercially useful end product, but such usefulness would be secondary 
to the act of destruction.'' Inclusion of the second sentence clarifies 
that the listed technologies in proposed section 84.29 that are 
conversion technologies are included within the proposed definition for 
destruction and are not considered transformation. Unlike the 
definition for this term in 40 CFR part 82, subpart A, EPA is proposing 
not to distinguish between destruction and completely destroy. The 
Agency expects that all destruction of regulated substances occurs at 
98 percent or greater, which was the definition for ``completely 
destroy.'' EPA is also proposing that the new definition not include a 
reference to the Parties. Lastly, in place of the part 82 list of 
approved technologies, EPA is proposing to list the technologies 
approved by the Administrator in Sec.  84.29.
    Confer. EPA is proposing to define this term as ``to shift 
unexpended application-specific allowances obtained in accordance with 
subsection (e)(4)(B)(iv) of the AIM Act from the end user allocated 
such allowances to another entity for the production or import of a 
regulated substance for use by the end user.'' This proposed term is 
intended to distinguish conferring an allowance, which is not subject 
to an offset, from an allowance transfer, which is subject to an 
offset.
    Facility. EPA is proposing to define this term in 40 CFR part 84 to 
mean ``one or more production lines at the same location owned by or 
under common control of the same person.'' This is similar to the 
definition of ``plant'' in 40 CFR part 82. This would align the 
definition of ``facility'' more closely with definitions used in other 
CAA regulatory programs, including the GHGRP. As discussed in the 
following section of the preamble, EPA is creating a new definition 
``production line'' that has the same meaning as the definition of 
``facility'' in 40 CFR part 82.
    Import. EPA is proposing to adopt the definition of the term 
``import'' contained in subsection (b) of the AIM Act, which is nearly 
identical to the definition of ``import'' in 40 CFR part 82, and add 
one of the three exemptions from the part 82 definition. EPA is 
proposing to include an exemption for the off-loading of used regulated 
substances from a ship during servicing. This occurs, for example, when 
a foreign ship's refrigeration system is serviced in a U.S. port and 
refrigerant that is recovered from that system is offloaded for 
reclamation or destruction. The alternatives would be requiring 
shipping companies to hold allowances or store the used refrigerant on 
board until reaching another country. Issuing allowances to shipping 
companies would be impractical as servicing can happen unexpectedly to 
any type of vessel and EPA does not have data on which to base an 
allocation. Prohibiting offloading is potentially problematic because 
it could result in venting of the

[[Page 27161]]

refrigerant when the ship is offshore rather than the proper 
reclamation or disposal that is required under EPA's refrigerant 
management regulations at 40 CFR part 82, subpart F.
    Metered dose inhaler. EPA is proposing to define MDIs as ``a 
handheld pressurized inhalation system that delivers small, precisely 
measured therapeutic doses of medication directly to the airways of a 
patient. MDIs treat health conditions such as asthma and chronic 
obstructive pulmonary disease and are approved for such use by the U.S. 
Food and Drug Administration (FDA).'' This definition is substantially 
similar to the definition of ``essential metered dose inhaler'' in 40 
CFR part 82 (except that the part 82 definition refers to a 
determination of essentiality by either the Parties to the Montreal 
Protocol or the FDA).
    Reclaim. EPA is proposing to define reclaim as ``the reprocessing 
of regulated substances to all of the specifications in appendix A of 
40 CFR part 82, subpart F (based on AHRI Standard 700-2016) that are 
applicable to that regulated substance and to verify that the regulated 
substance meets these specifications using the analytical methodology 
prescribed in section 5 of appendix A of 40 CFR part 82, subpart F.''

C. What new definitions is EPA proposing?

    Subsection (b) of the AIM Act defines some specific terms and the 
Act as a whole introduces other new terms that it does not define. EPA 
is proposing to establish definitions for a number of new terms that 
are relevant for the allowance allocation and trading program. These 
terms are: Allowance, Application-specific allowance, Bulk, Chemical 
vapor deposition chamber cleaning, Defense spray, Etching, Exchange 
value, Exchange value equivalent, Final customer, Mission-critical 
military end uses, On board aerospace fire suppression, Process agent, 
Production/Produce, Production line, Regulated substance, and 
Structural composite preformed polyurethane foam.
    Allowance. The AIM Act defines allowance as a limited authorization 
for the production or consumption of a regulated substance established 
under subsection (e). EPA is proposing to adopt that definition and add 
that an allowance allocated under this subsection does not constitute a 
property right as stated in subsection (e)(2)(D)(ii)(aa) and that an 
allowance allocated under the authority of the AIM Act can be retired, 
revoked, or withheld at the discretion of the relevant Agency official. 
EPA notes that the framework for issuing allowances is subject to 
change through notice and comment rulemaking.
    Application-specific allowance. EPA is proposing to establish a new 
category of allowances that would be issued only to entities in the six 
listed applications at (e)(4)(B)(iv) of the AIM Act. EPA is proposing 
to define this term as ``a limited authorization granted in accordance 
with subsection (e)(4)(B)(iv) of the AIM Act for the production or 
import of a regulated substance for use in the specifically identified 
applications that are listed in that subsection and in accordance with 
the restrictions contained at Sec.  84.5(c). An application-specific 
allowance does not constitute a property right and can be retired, 
revoked, or withheld at the discretion of the relevant Agency 
official.''
    Bulk. EPA is proposing to define this term 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.'' EPA is proposing to define 
this term so as to distinguish between a regulated substance that is in 
a container from a regulated substance that is in a product or other 
type of use system. The examples provided in the definition are not 
exclusive.
    Chemical vapor deposition chamber cleaning. EPA is proposing to 
define this term as, ``in the context of semiconductor manufacturing, a 
process type in which chambers used for depositing thin films are 
cleaned periodically using plasma-generated fluorine atoms and other 
reactive fluorine-containing fragments.'' This definition is closely 
based on the source category definition for electronics manufacturing 
in the GHGRP (40 CFR 98.90(a)(2)).
    Defense spray. EPA is proposing to define this term as ``an 
aerosol-based spray used for self-defense, including pepper spray and 
animal sprays, and containing the irritant capsaicin and related 
capsaicinoids (derived from oleoresin capsicum), an emulsifier, and an 
aerosol propellant.'' EPA is taking comment on whether this definition 
is inclusive of defense sprays potentially covered by subsection 
(e)(4)(B)(iv) of the AIM Act.
    Etching. EPA is proposing to define etching as, ``in the context of 
semiconductor manufacturing, a process type that uses plasma-generated 
fluorine atoms and other reactive fluorine-containing fragments that 
chemically react with exposed thin-films (e.g., dielectric, metals) or 
substrate (e.g., silicon) to selectively remove portions of material.'' 
This definition is closely based on the definition of the electronics 
manufacturing source category in the GHGRP (40 CFR 98.90(a)(1)).
    Exchange value. The AIM Act defines ``exchange value'' as the value 
assigned to a regulated substance in accordance with subsections (c) 
and (e), as applicable. Subsection (c) includes a list of regulated 
substances with listed exchange values. Subsection (e) includes a list 
of ODS with listed exchange values. EPA is proposing to adopt the 
definition contained in the AIM Act, including the tables, which EPA 
would replicate in Appendix A of 40 CFR part 84.
    Exchange value equivalent. This proposal also uses the term 
``exchange value equivalent'' or ``EVe'' to provide a common unit of 
measure. EPA is proposing to define EVe to be determined by multiplying 
the mass of a regulated substance by the exchange value of that 
substance. For example, 50 kilograms of HFC-134a would be 71,500 kgEVe 
(50 x 1,430). This can also be written as 71.5 metric tons exchange 
value equivalent (MTEVe). EPA is proposing to issue allowances in units 
of one MTEVe. This proposal also uses the term ``EV-weighted'' to 
describe a number presented in exchange value equivalents. For example, 
EPA is proposing that the size of an allowance be one EV-weighted ton.
    EVe allows for the comparison between, and calculation with, 
different regulated substances. For example, a blend containing 
multiple regulated substances would have an EVe that could be used to 
determine the quantity of allowances needed to produce or consume the 
regulated HFCs that are components of the blend. However, the EVe would 
only reflect the components of the blend that are regulated substances 
under the AIM Act. In situations where the blend contains components 
that are not regulated substances (e.g., hydrofluoroolefins or HFOs), 
the EVe would not match the GWP of the blend and would be slightly 
lower. This would be the case for blends

[[Page 27162]]

R-448A,\29\ R-449A, and R-450A, which contain a mix of HFCs and HFOs.
---------------------------------------------------------------------------

    \29\ There are a number of different blends that contain HFCs 
and non-regulated substances such as HFOs. As an example, the blend 
R-448A is made of five components, three of which are HFCs regulated 
under the AIM Act and two HFOs. The percentage of the blend and the 
exchange value of the constituents are: 26 percent HFC-32 (675), 26 
percent HFC-125 (3,500), 21 percent HFC-134a (1,430), 20 percent 
HFO-1234yf (0), and 7 percent HFO-1234ze (0). The contribution of 
each HFC to the total EVe of the blend is calculated by multiplying 
the percentage of the blend made up of that HFC times its EVe, and 
the sum of the contributions of all the blend constituents is the 
blend EVe. Thus, the EVe of R-448A is (0.26 x 675) + (0.26 x 3,500) 
+ (0.21 x 1,430) + (0.20 x 0) + (0.07 x 0) = 1,385.8.
---------------------------------------------------------------------------

    Final customer. EPA is proposing to define this term as ``the last 
person to purchase a bulk regulated substance before its intended 
use.'' For each use of HFCs, the final customer can be different. For 
example, an air-conditioning contractor would generally be the final 
customer in the residential air conditioning market. For foams, the 
foam systems house would be the final customer, as they are making a 
product (i.e., a foam system). Likewise, aerosol fillers, semiconductor 
manufacturers, air-conditioning and refrigeration equipment 
manufacturers that ship equipment pre-charged, fire extinguisher 
manufacturers would be the final customer. EPA seeks comment on whether 
a list of examples like this should be incorporated into the 
definition.
    Mission-critical military end uses. EPA is proposing to define this 
term as ``those uses of regulated substances by an agency of the 
Federal Government responsible for national defense which have a direct 
impact on mission capability, as determined by the U.S. Department of 
Defense, including, but not limited to uses necessary for development, 
testing, production, training, operation, and maintenance of Armed 
Forces vessels, aircraft, space systems, ground vehicles, amphibious 
vehicles, deployable/expeditionary support equipment, munitions, and 
command and control systems.''
    On board aerospace fire suppression. EPA is proposing to define 
this term as ``use of a regulated substance in fire suppression 
equipment used on board commercial and general aviation aircraft and 
space vehicles. On board commercial aviation fire suppression systems 
are installed throughout mainline and regional passenger and freighter 
aircraft, including engine nacelles, auxiliary power units (APUs), 
lavatory trash receptacles, baggage/crew compartments, and handheld 
extinguishers.'' EPA takes comment on whether this definition should 
include general aviation, which consists of private and/or business 
aircraft, which may not have the same requirements as commercial 
aircraft for on board fire suppression systems. This definition 
excludes military aircraft because they are already covered under the 
definition of mission-critical military end uses. EPA has previously 
defined ``space vehicle'' under Title VI regulations at 40 CFR 82.3 as 
a man-made device, either manned or unmanned, designed for operation 
beyond earth's atmosphere. This definition includes integral equipment 
such as models, mock-ups, prototypes, molds, jigs, tooling, hardware 
jackets, and test coupons. Also included is auxiliary equipment 
associated with test, transport, and storage, which through 
contamination can compromise the space vehicle performance. EPA takes 
comment on whether space vehicle, as defined above, is inclusive of 
applications that would be considered as on board fire suppression. EPA 
requests relevant information on HFC use in these applications.
    Process agent. The AIM Act uses the term ``process agent'' without 
defining it. EPA is proposing to define the term as ``the use of a 
regulated substance to form the environment for a chemical reaction 
(e.g., use as a solvent, catalyst, or stabilizer) where the regulated 
substance is not consumed in the reaction, but is removed or recycled 
back into the process and where no more than trace quantities remain in 
the final product. A feedstock, in contrast, is consumed during the 
reaction.'' \30\ This definition matches the definition used by the 
Montreal Protocol's Technology and Economic Assessment Panel (TEAP) and 
is well-established and understood in the ODS context.\31\
---------------------------------------------------------------------------

    \30\ The term ``consume'' in the AIM Act has two separate 
meanings. In the context of describing transformation/feedstock uses 
of HFCs, the word ``consume'' is used to mean the decomposition of 
the substance. For example, subsection (b)(7)(B) excludes from the 
definition of ``produce'' ``the manufacture of a regulated substance 
that is used and entirely consumed (except for trace quantities) in 
the manufacture of another chemical.'' (emphasis added).

Layer, Medical and Chemical Technical Options Committee 2018 
Assessment Report (United Nations Environmental Programme, 2018). 
https://ozone.unep.org/sites/default/files/2019-04/MCTOC-Assessment-Report-2018.pdf.
---------------------------------------------------------------------------

    Production/Produce. EPA is proposing to adopt the definition of the 
term ``produce'' that is found in subsection (b) of the AIM Act. While 
substantially similar to the definition of the term ``production'' at 
40 CFR 82.3, there are a few differences. First, the AIM Act definition 
does not use the word ``transformed'' but rather textually incorporates 
most of the definition of the defined term ``transform'' from Sec.  
82.3. Second, the definition specifically excludes the reclamation of a 
regulated substance from the term production. This exclusion was not 
found in Sec.  82.3 but matches EPA's long-held interpretation in CAA 
Title VI programs that reclamation does not constitute production and 
that reclaimed material is inherently reused/recycled.
    In addition, EPA is proposing to specifically exclude from 
production ``the inadvertent or coincidental creation of insignificant 
quantities of a regulated substance during a chemical manufacturing 
process, resulting from unreacted feedstock, from the listed 
substance's use as a process agent present as a trace quantity in the 
chemical substance being manufactured, or as an unintended byproduct of 
research and development applications.'' This phrase appears in the 40 
CFR 82.3 definition of ``controlled substance.'' EPA is proposing that 
the exclusion of these insignificant quantities is more properly 
considered in defining what qualifies as production given they describe 
acts of ``creation'' or ``resulting from'' or ``byproduct of.'' Under 
this proposal, such insignificant quantities created in the above-
listed circumstances would be considered regulated substances, but 
would not be considered production. Combining all of the exclusions 
under one term increases clarity when interpreting the terms 
``produce'' and ``regulated substance'' together.
    Production line. EPA is proposing to define the term ``production 
line'' to mean ``any process equipment (e.g., reactor, distillation 
column) used to convert raw materials or feedstock chemicals into 
regulated substances or consume regulated substances in the production 
of other chemicals.'' In 40 CFR part 82, EPA used this same description 
to define the term ``facility.'' The Agency considers the term 
``production line'' to be more consistent with common usage in the 
chemical industry to refer to a specific set of process equipment, as 
opposed to the buildings and land where production takes place.
    Regulated substance. The AIM Act uses the term ``regulated 
substance'' to refer to HFCs statutorily listed in the AIM Act and any 
such substance added to the list in future consistent with subsection 
(c)(3)(A). EPA is proposing to define the term as ``a hydrofluorocarbon 
listed in the table contained in subsection (c)(1) of the AIM Act and a 
substance included as a regulated substance by the Administrator under

[[Page 27163]]

the authority granted in subsection (c)(3). A current list of regulated 
substances can be found in appendix A of this part.''
    Structural composite preformed polyurethane foam. EPA is proposing 
to define this term as ``a foam blown from polyurethane that is 
reinforced with fibers and with polymer resin during the blowing 
process, and is preformed into the required shape (e.g., specific boat 
or trailer design) to increase structural strength, while reducing the 
weight of such structures.''
    EPA welcomes comment on these proposed defined terms and whether 
any additional terms should be defined in this rulemaking.

V. How is EPA proposing to establish the HFC production and consumption 
baselines?

    The first step in phasing down HFCs through an allowance allocation 
and trading program is to establish the U.S. production and consumption 
baselines. It is from these baselines that the total annual production 
and consumption allocations can be derived in a stepwise manner over 
time.

A. What are the components of the production and consumption baselines?

    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. The equations comprise an HFC component, an 
HCFC component, and a CFC component. Specifically, the production 
baseline is equal to the sum of: (i) The average annual quantity of all 
regulated substances produced in the United States from January 1, 
2011, through December 31, 2013, and (ii) 15 percent of the production 
level of HCFCs in calendar year 1989, and (iii) 0.42 percent of the 
production level of CFCs in calendar year 1989. For the purposes of 
establishing the baselines, EPA must use the exchange values assigned 
by Congress to develop an exchange value-weighted amount for both 
production and consumption. The equation representing the production 
baseline calculation is:
[GRAPHIC] [TIFF OMITTED] TP19MY21.000

Similarly, the AIM Act defines the consumption baseline as equal to the 
sum of (i) the average annual quantity of the consumption \32\ of 
regulated substances in the United States from January 1, 2011, through 
December 31, 2013, and (ii) 15 percent of the consumption of HCFCs in 
calendar year 1989, and (iii) 0.42 percent of the consumption of CFCs 
in calendar year 1989. The equation representing the consumption 
baseline calculation is below.
---------------------------------------------------------------------------

    \32\ Consumption is equal to production plus imports minus 
exports.
[GRAPHIC] [TIFF OMITTED] TP19MY21.001

    In developing the proposed HFC consumption baseline, EPA is 
proposing to include HFCs that are bulk chemicals and exclude HFCs that 
are contained in a product. This proposal is based on EPA's experience 
implementing similar provisions under CAA Title VI for ODS.\33\ The CAA 
Title VI provisions are written and structured similarly to the AIM Act 
provisions, and therefore it is reasonable to interpret and implement 
those terms in a similar manner. Under the phaseout requirements for 
ODS (40 CFR part 82, subpart A), only imports and exports of bulk 
controlled substances are counted as part of the consumption cap.\34\ 
Using a different mechanism under the HFC phasedown could create 
confusion and would likely cause disruption within the imported 
products market. Specifically, many companies that import bulk HFCs 
also imported bulk ODS substances and are therefore familiar with EPA's 
regulations and allocation program used to phaseout ODS under Title VI 
of the Clean Air Act. If the HFC allocation framework under the AIM Act 
were expanded beyond bulk substances to include products containing 
HFCs, the regulated importer community would be many times greater, 
would likely be caught unawares, and would encompass entities 
unfamiliar with EPA's general approach to the allocation program. 
Further, if the Agency were to include HFCs contained in products in 
the baseline figures, it also would need to include data reflecting 
HCFCs and CFCs

[[Page 27164]]

contained in products in 1989 to complete the baseline formula. The 
Agency does not have this data and given the amount of time that has 
passed since 1989, it would be administratively infeasible to collect 
such data now (as opposed to bulk CFC and bulk HCFC data which the 
Agency already collected many years ago). Given the indications that 
subsection (e) of the AIM Act does contemplate regulation of bulk 
substances--such as the exceptions for feedstocks and process agents 
(which are both examples of bulk substances) in subsection (e)(4)(A) 
and the references in (e)(4)(B)(i) and (iv) to allocation of allowances 
for use of regulated HFCs in particular applications--and given that it 
does not appear to contemplate the implications of importing products 
or equipment, EPA believes that this proposed interpretation is 
consistent with the goals of the Act.
---------------------------------------------------------------------------

    \33\ This approach is also consistent with the approach taken 
under the Montreal Protocol. Decision I/12A, taken at the first 
Meeting of the Parties to the Montreal Protocol, defines 
``controlled substances'' as bulk chemical. As such, the production 
and consumption schedules under the Montreal Protocol only apply to 
bulk chemical.
    \34\ For purposes of implementing the ODS phaseout regulations 
(40 CFR part 82, subpart A), EPA defined a controlled substance, in 
part, as any listed ODS, whether existing alone or in a mixture, but 
excluding any such substance or mixture that is in a manufactured 
product other than a container used for the transportation or 
storage of the substance or mixture. Any amount of a listed 
substance that is not part of a use system containing the substance 
is a controlled substance. If a listed substance or mixture must 
first be transferred from a bulk container to another container, 
vessel, or piece of equipment in order to realize its intended use, 
the listed substance or mixture is a ``controlled substance.''
---------------------------------------------------------------------------

    EPA is also proposing not to include transhipments within the 
baseline. A transhipment is the continuous shipment of a regulated 
substance, from a foreign country of origin through the United States, 
to a second foreign country of final destination. Transhipments do not 
enter interstate commerce in the United States. EPA proposes to not 
include transhipments in the baseline calculation because the sum 
effect of this activity would be zero--the regulated substance is both 
imported (which would be added to the consumption baseline) and 
exported (which would be subtracted from the consumption baseline) in 
identical quantities.
1. How is EPA proposing to determine the HFC component of the 
production and consumption baselines?
    In order to calculate the production and consumption baselines, EPA 
must determine the annual production and consumption of the statutorily 
listed HFCs in the years 2011, 2012, and 2013. EPA is proposing to use 
three sources of data in order to calculate HFC consumption and 
production figures for 2011 through 2013: (1) Data reported to EPA's 
GHGRP; (2) data received in response to EPA's ongoing and planned 
outreach, including the notice of data availability (NODA) published 
February 11, 2021, stakeholder meetings, and planned letters sent out, 
including under CAA section 114; and (3) any data received in response 
to this notice of proposed rulemaking by the comment due date.
(a) What is the GHGRP and what data are available from it?
    The GHGRP was established in 2009 and requires various facilities 
and suppliers to annually report data related to GHGs to EPA (see 40 
CFR part 98). The relevant subpart that relates to reporting on HFC 
production and consumption is subpart OO, ``Suppliers of Industrial 
Greenhouse Gases.'' Because the HFCs listed as regulated substances 
under the AIM Act are industrial GHGs, EPA has been collecting since 
the GHGRP's inception a significant amount of data relevant to HFC 
production and consumption as defined under the AIM Act. EPA can use 
these data to begin approximating the historic HFC production and 
consumption figures necessary to calculate baselines under the AIM 
Act.\35\
---------------------------------------------------------------------------

    \35\ While EPA determined that chemical-specific GHG data at the 
facility and importer/exporter level is CBI, EPA also determined 
that it would release the data in aggregated amounts as long as the 
aggregations meet the criteria outlined in the Federal Register 
notice cited here. For purposes of the data presented in the NODA 
accompanying this rulemaking and in the docket for this proposed 
rule, EPA determined that release of the aggregated data would not 
disclose CBI. The data presented in this proposed rule are 
aggregations for which the aggregation criteria have been met to 
ensure the underlying CBI is shielded from public disclosure, and 
the individual reporters have been notified of EPA's intent to 
aggregate.
---------------------------------------------------------------------------

    Under the GHGRP, reporting and other requirements apply to the 
facility or supplier based on the source and/or supplier categories 
located at the facility, their emission and/or supply levels (as 
applicable to a source or supplier category), and other factors. 
Facilities that undertake some types of activities (e.g., import or 
export of fluorinated GHGs) \36\ must report for that source or 
supplier category only if their emissions or supplies (or related 
quantities) meet or exceed a threshold. Facilities that undertake other 
types of activities (e.g., fluorinated GHG production) are required to 
report for at least three years regardless of the magnitude of their 
emissions or supplies. Once data are submitted, EPA conducts a multi-
step verification process to ensure reported data are complete and 
accurate.
---------------------------------------------------------------------------

    \36\ For the purposes of the GHGRP and this proposal, the term 
``fluorinated GHGs'' does not include controlled substances under 
CAA Title VI.
---------------------------------------------------------------------------

    Subpart OO captures the vast majority of the bulk HFC production, 
import, and export in the United States. Subpart OO requires reporting 
from producers of HFCs and certain importers, exporters, and destroyers 
of HFCs. The data reported are by chemical, and thus, EPA can exclude 
from the calculation of baselines any HFCs reported to the GHGRP that 
are not listed as regulated substances under the AIM Act. All producers 
of HFCs, as defined in 40 CFR 98.410(b), are required to report the 
quantities that they produce, transform (unless the transformed 
feedstock is produced onsite), destroy, or send off-site for 
transformation or destruction, unless otherwise provided in subpart OO. 
Importers with bulk imports of N2O, fluorinated GHGs, and 
CO2 that in combination are equivalent to 25,000 metric tons 
of carbon dioxide equivalent (MTCO2e) or more are required 
as part of their annual report to report the quantities that they 
import, destroy, or send off-site for transformation or destruction. 
Exporters with bulk exports of N2O, fluorinated GHGs, and 
CO2 that in combination are equivalent to 25,000 
MTCO2e or more are required as part of their annual report 
to report the quantities that they export.
    As a result of these requirements, the data provided through the 
GHGRP reflects most of the production, import, export, and destruction 
of regulated substances for the baseline years. However, EPA is aware 
of some data that are not collected through GHGRP that are relevant for 
calculating the HFC component of the AIM Act baselines.
    Companies that import or export fewer than 25,000 MTCO2e 
of industrial gases, including HFCs, are exempted from reporting.\37\ 
Analyses performed during the development of the GHGRP indicated that 
this threshold would have minimal impact on the overall topline number 
of HFCs imported and exported, exempting less than one percent of the 
GWP-weighted quantities of industrial GHGs in containers that are 
imported or exported.\38\ This high coverage is due in part to the high 
GWPs of fluorinated GHGs, including HFCs, which trigger reporting at 
relatively low volumes (e.g., 17.5 metric tons (MT) for HFC-134a or 7.2 
MT of HFC-125), and in part to the fact that the largest importers and 
exporters account for the

[[Page 27165]]

majority of the imported and exported quantities.
---------------------------------------------------------------------------

    \37\ For importers and exporters, the GHGRP also exempts the 
reporting of individual shipments containing less than 25 kg of 
fluorinated GHGs. In an analysis performed in 2006, EPA found that 
exempting such shipments would reduce the total quantity of 
industrial GHGs reported by only 0.01 percent. Thus, this exemption 
is not likely to have a material impact on the figures used for 
imports and exports in calculating the AIM Act consumption baseline.
    \38\ See the Technical Support Documents for subpart OO (below). 
One caveat is that this is based on data from 2006, and it is 
possible that import and export patterns have changed since then.

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

    EPA routinely reviews import data provided by U.S. Customs and 
Border Protection (CBP) to verify reported supply data and identify 
facilities that may be subject to annual GHG reporting under 40 CFR 
part 98. Based on this review and other information, there also appear 
to be companies that imported or exported more than 25,000 
MTCO2e of HFCs annually that have not reported imports or 
exports to the GHGRP. Section V.B.2 of this proposal provides 
instructions for late reporting.
    Subpart OO also does not require the reporting of HFC-23 that is 
intentionally coproduced, captured, and refined for use, or 
unintentionally created. Consequently, EPA is lacking data related to 
the creation of HFC-23 and any subsequent destruction or refinement for 
sale. To address this data gap, EPA has sought information from 
facilities that create HFC-23, either intentionally or unintentionally. 
EPA is not docketing the individual responses related to HFC-23 due to 
companies' CBI claims, but has included aggregated data in the analyses 
in the docket.
    Two other data gaps include (1) the amounts of HFCs other than HFC-
23 that were destroyed by free-standing destruction facilities (i.e., 
facilities that destroy HFCs but do not import or produce) during the 
baseline years \39\ and (2) any amounts of HFCs that were transformed 
by facilities that transform HFCs but that do not also produce them 
(which is necessary to determine the quantity of HFCs that are produced 
for use as feedstock).
---------------------------------------------------------------------------

    \39\ Such facilities have only been required to report the 
quantities that they destroy since 2019, when they reported their 
destruction for 2018.
---------------------------------------------------------------------------

    Not accounting for quantities that were destroyed or transformed 
would result in overestimates of production and consumption as those 
quantities are defined under the AIM Act, since the quantities 
destroyed or transformed are subtracted from GHGRP production to obtain 
AIM Act production. While EPA is not aware of any facilities in the 
U.S. that transform HFCs but do not produce HFCs, we cannot rule out 
the possibility that they exist.
(b) What outreach is EPA doing to collect data to fill known gaps in 
the GHGRP?
    As outlined in the prior section, the data available through GHGRP 
will significantly contribute to EPA's ability to calculate the amount 
of HFCs produced and consumed in the United States in 2011-2013 for 
purposes of determining the AIM Act baselines. However, there are known 
gaps in the GHGRP data, and EPA is making best efforts to fill these 
gaps. Specifically, EPA published a NODA on February 11, 2021, 
outlining the same information provided in the prior section concerning 
what data are available through GHGRP and where EPA perceived data gaps 
(86 FR 9059). EPA invited the public to provide additional data and 
identify other potential gaps in EPA's knowledge. In response to the 
NODA, EPA received 29 public comments which can be found in the docket 
for this rulemaking, five comments containing material claimed as CBI, 
and at least one additional report of historic HFC data not previously 
reported to the GHGRP. EPA received a number of public comments that 
were outside of the scope of the NODA, i.e., several comments were not 
germane to additional data that could help inform the HFC production 
and consumption baselines for 2011, 2012, and 2013. Some of these 
comments focused on implementation of various provisions of the AIM 
Act, including but not limited to allocation methodology, the statutory 
years used to establish the HFC production and consumption baselines, 
application-specific allowances, and projected market trends for, and 
associated with, various end uses of the regulated HFCs. EPA 
appreciates these comments and, in some instances, has proposed 
provisions in this rulemaking that address several of the specific 
points or has integrated specific points into section XI of the 
preamble, which includes the ANPRM. Nonetheless, the Agency's intent in 
releasing the NODA was to ask for additional data that could inform the 
HFC production and consumption baseline for 2011, 2012, and 2013. The 
Agency has reviewed the comments submitted containing material claimed 
as CBI as well as the data submitted via e-GGRT, and to the extent that 
these submissions fill in our known data gaps, the proposed HFC 
production and consumption baseline reflect this information and data 
accordingly. Some of the information received starts to fill in the 
gaps EPA identified in the NODA and above. EPA continues to invite 
public input through this proposed rulemaking and welcomes provision of 
additional data related to HFC production and consumption in the years 
2011, 2012, and 2013.
    EPA has separately requested approval under the Paperwork Reduction 
Act to collect missing data \40\ and intends to send letters under the 
authority of subsection (k)(1)(C) of the AIM Act and section 114 of the 
CAA to companies who may have relevant data.

    EPA also held a stakeholder meeting on February 25, 2021. 
Approximately 200 people participated in the stakeholder meeting to 
learn more about the AIM Act and how EPA was moving forward with 
implementation. At that meeting, EPA reminded stakeholders to submit 
relevant data to help inform this rulemaking. Additionally, five 
stakeholder workshops were held between March 11, 2021, and March 12, 
2021, specific to stakeholders interested in the statutorily listed 
applications identified in AIM Action section (e)(4)(B)(iv); as with 
the February 25, 2021, stakeholder meeting, these workshops provided 
participants the opportunity to learn more about the AIM Act and how 
EPA was moving forward with implementation. One workshop was held for 
each sector identified in AIM Act section (e)(4)(B)(iv). EPA did not 
hold a stakeholder workshop for the mission-critical military sector 
because, as will be explained in a subsequent section of this preamble, 
EPA is working directly with the Department of Defense on distributing 
allowances for mission-critical military end uses. Stakeholders at each 
workshop were similarly reminded during these workshops to submit 
relevant data to help inform this rulemaking. In addition, EPA has met 
with numerous stakeholders and participated in meetings sponsored by 
other government and non-government entities (e.g., Small Business 
Administration's February 26, 2021, small business environment 
roundtable). A full list of meetings EPA has conducted with 
stakeholders is provided in the rulemaking docket.
    For anyone seeking to submit data to the Agency regarding HFC 
production, consumption or use in the six applications listed in 
subsection (e)(4)(B)(iv) of the AIM Act, please contact the individual 
listed under FOR FURTHER INFORMATION CONTACT.
2. What is the current HFC component of the production and consumption 
baselines?
    The equations in the AIM Act for the production and consumption 
baselines include the average annual production and consumption of HFCs 
between January 1, 2011, and December 31, 2013. Based on the 
information reported to the GHGRP and gathered through recent data 
collection efforts, EPA estimates average HFC consumption at 256 
million metric tons of exchange value equivalent (MMTEVe) and HFC 
production at 331 MMTEVe for those

[[Page 27166]]

three years. A memo to the docket (``HFC Production and Consumption 
Data--Proposed Rule'') provides the current aggregated data for each of 
the three years similar to that provided in the NODA, as well as a list 
of companies that have reported data to EPA for those years. EPA 
anticipates that these values will change in the final rule as the 
Agency continues to collect additional data.
3. What are the HCFC and CFC components of the production and 
consumption baselines?
    The equations in the AIM Act for the production and consumption 
baselines include HCFC and CFC components from 1989. That year was 
designated under the Montreal Protocol as the baseline year used for 
several class I substances (Groups III, IV, and V in the Montreal 
Protocol) as well as for class II substances (HCFCs). See, e.g., 74 FR 
66412 (December 15, 2009). As a result, EPA has previously developed a 
complete accounting of ODS production, import, and export during that 
year and is therefore not specifically requesting comment on that 
value.\41\
---------------------------------------------------------------------------

    \41\ For more information on historic U.S. ODS production and 
consumption data, please visit the United Nations Environment 
Program's website at https://ozone.unep.org/countries/profile/usa.
---------------------------------------------------------------------------

    Specifically, the 1989 production and consumption levels for HCFCs 
are 216.9 MMTEVe and 210.3 MMTEVe respectively, and the 1989 production 
and consumption baselines for CFCs are 2,799.8 MMTEVe and 2,784.5 
MMTEVe respectively. Fifteen percent of the 1989 HCFC production and 
consumption baselines is 32.5 MMTEVe and 31.5 MMTEVe respectively, 
while 0.42 percent of the 1989 CFC production and consumption baselines 
is 11.8 MMTEVe and 11.7 MMTEVe respectively.

B. What are the proposed HFC production and consumption baselines?

    Using the equation provided in the AIM Act, based on the data 
currently available to EPA (which, as noted in the prior section, EPA 
is still working to refine), EPA proposes to find that the U.S. 
production baseline is 375 MMTEVe and the U.S. consumption baseline is 
299 MMTEVe. To provide the most accurate production and consumption 
baselines, EPA reiterates its request for data submissions and other 
information relevant to HFC production and consumption in 2011, 2012, 
and 2013. Once established through the final rule, EPA does not intend 
to amend the baselines. While EPA is taking comment on the inputs to 
the calculation, the Agency notes that the formulas used for 
calculating the baselines are established in the AIM Act.

VI. How is EPA proposing to establish allowances?

    This section provides an overview of how EPA intends to establish a 
system providing for HFC production and consumption allowances and 
EPA's proposed methodology for issuing allowances. The AIM Act in 
subsection (e)(3) requires EPA to conduct a rulemaking to phase down 
production and consumption of regulated substances in the United States 
through an allowance allocation and trading program. Aside from 
establishing the cap on the allowance program (by defining how to 
calculate the baseline and requiring a set percentage reduction in 
specific years from that baseline), the AIM Act provides EPA 
considerable discretion in determining how to establish the allowance 
program and how to allocate allowances in that program. Because EPA has 
experience phasing out production and consumption of ODS under Title VI 
of the CAA in similar industries, EPA is using that experience to 
inform this proposal.\42\
---------------------------------------------------------------------------

    \42\ Collectively, EPA's regulations governing the phaseout of 
ODS can be found in Subpart A to 40 CFR part 82. https://ecfr.federalregister.gov/current/title-40/chapter-I/subchapter-C/part-82.
---------------------------------------------------------------------------

A. What is an allowance?

    EPA uses an allowance as the unit of measure that controls 
production and consumption. Subsection (e)(2)(D)(ii) of the AIM Act 
specifies that an allowance allocated by EPA under the AIM Act is a 
limited authorization for the production or consumption of a regulated 
substance and does not constitute a property right. EPA is proposing 
that the Agency would issue allowances that would be valid between 
January 1 and December 31 of a given year, also known as a ``calendar-
year allowance.'' A calendar-year allowance represents the privilege 
granted to a company to produce or import regulated substances in that 
year. EPA proposes to allocate production allowances, consumption 
allowances, and ``application-specific allowances'' for six uses 
specified in the Act.\43\ EPA proposes that producing HFCs would 
require expending both production allowances and consumption 
allowances, since production is a component of the AIM Act definition 
of what composes consumption. Importing HFCs would require expending 
only consumption allowances. This is the mechanism EPA has used to 
implement the ODS phaseout and would meet the expectations of, and be 
understood by, producers and importers of HFCs. This design also helps 
EPA ensure that both the production and consumption caps from the AIM 
Act will be met through the allowances allocated. As discussed later, 
EPA is proposing that ``application-specific allowances'' are a third 
category of allowances that can be

[[Page 27167]]

expended to either produce or import HFCs.
---------------------------------------------------------------------------

    \43\ The ODS framework also issued allowances for specific uses 
such as an essential use allowance or a critical use allowance.
---------------------------------------------------------------------------

    EPA is proposing that producing or importing HFCs that will be used 
and entirely consumed (except for trace quantities) in the manufacture 
of another chemical (i.e., for use as a feedstock, which is also known 
as transformation) would not require expending production or 
consumption allowances. In general, such HFCs are exempted from the 
term ``produce'' under subsection (b) of the AIM Act. However, HFCs 
intended to be used for transformation are regulated substances and 
thus certain provisions, such as recordkeeping and reporting, apply to 
them to verify that they are in fact transformed. As such, EPA is 
proposing that an importer must submit a petition and receive a non-
objection notice before importing HFCs for transformation. EPA 
discusses proposed recordkeeping and reporting requirements for HFCs 
that are intended to be used for transformation in section IX.D of this 
preamble.
    The definition of ``Produce'' in the AIM Act and as proposed in 
this rulemaking explicitly excludes the reclamation, reuse, or 
recycling of a regulated substance. Because the definition of 
``Consumption'' includes production, EPA intends to not include the 
amounts of domestically reclaimed HFCs for calculating the yearly 
production or consumption limits. The AIM Act does not exempt HFCs that 
have been reclaimed or otherwise reprocessed from consideration when 
determining the volume of HFCs imported into the United States. EPA is 
therefore proposing to require consumption allowances for the import of 
reclaimed HFCs, unless the reclaimed HFCs are being imported solely for 
the purpose of destruction. In the situation of reclaimed HFCs imported 
solely for the purpose of destruction, if the imported reclaimed HFCs 
were counted towards consumption, it would be subtracted back out when 
destroyed. If a consumption allowance were required to be expended in 
this circumstance, EPA would likely give that allowance back after the 
substance was destroyed. In this circumstance, it seems appropriate to 
simply permit reclaimed HFCs to be imported solely for purposes of 
destruction without expenditure of an allowance, assuming it can be 
reasonably demonstrated that the HFC will in fact be destroyed. EPA is 
accordingly proposing recordkeeping and reporting requirements in Sec.  
84.31. There is further discussion of the proposed process related to 
import of used HFCs for destruction in section VIII.F. of this 
preamble.
    EPA is also proposing that producers of HFCs need not expend 
production or consumption allowances if the HFCs are destroyed in a 
timely manner using an approved technology. More specifically, EPA 
proposes that if a company intends to utilize onsite destruction 
capability, the company does not need to expend allowances for the HFC 
production if the HFCs are destroyed within 30 days. If a company 
intends to utilize offsite destruction capability, the company need not 
expend allowances for the HFC production if the HFCs are destroyed 
within 90 days. These timelines seem achievable as a practical matter 
while being short enough to avoid potential malfeasance that could 
occur over an elongated time horizon. EPA welcomes comment on this 
question and would consider longer time windows if necessary, to allow 
companies adequate time to destroy these chemicals.
    This proposal is consistent with the definition of ``Produce'' in 
the AIM Act, which excludes ``the destruction of a regulated substance 
by a technology approved by the Administrator.'' HFCs that are 
domestically produced but are intended for destruction are regulated 
substances and thus certain provisions, such as recordkeeping and 
reporting, apply to them to verify that they are in fact destroyed. As 
discussed in the definitions section, EPA is proposing to exclude from 
production ``the inadvertent or coincidental creation of insignificant 
quantities of a regulated substance during a chemical manufacturing 
process, resulting from unreacted feedstock, from the listed 
substance's use as a process agent present as a trace quantity in the 
chemical substance being manufactured, or as an unintended byproduct of 
research and development applications.'' Under this proposal, such 
insignificant quantities created through the above-listed circumstances 
would not be considered production. The necessary implication of this 
proposed definition is that any other regulated substances created 
during the manufacturing process, either in quantities that are not 
insignificant or outside of the listed circumstances, would be 
considered ``production'' and would require expenditure of production 
and consumption allowances unless destroyed in a timely manner (there 
are additional restrictions related to HFC-23, as discussed further in 
subsection F). This proposal is intended to ensure that the regulated 
substances identified under the AIM Act are appropriately controlled 
and their production and consumption are reduced under the schedule 
outlined by Congress. Whether the regulated substance is inadvertently 
created through the chemical manufacturing process does not seem to be 
relevant to Congress's directive to phase down regulated substances on 
the statutorily defined schedule.
    EPA is proposing that any import of bulk regulated substance in any 
quantity requires consumption allowances. This would include a company 
that brings into the United States a rail car, tank truck, or ISO tank 
containing a heel of regulated substances. It would also include 
imports of HFCs that are classified as ``U.S. goods returned.'' In such 
situations, the company would need to expend consumption allowances for 
the import. As with the proposal related to production, this proposal 
is intended to ensure that all the regulated substances identified 
under the AIM Act are appropriately phased down according to the 
schedule outlined. EPA is additionally concerned that providing an 
exemption for imports of heels or U.S. goods returned could provide 
avenues for illegal imports of HFCs if an entity were to mislabel a 
full container as only containing a heel or foreign produced material 
as a U.S. good returned. EPA is interested in comments, however, on 
whether it should consider exempting heels or U.S. goods returned as a 
necessary part of importers' standard practice to enable easier import 
and export of regulated substances.
    However, EPA is proposing that companies that tranship HFCs do not 
need to expend allowances for that transhipment. In order to meet the 
definition of transhipped material, the HFCs cannot enter interstate 
commerce. Transhipped materials are also, by design, intended to be 
imported into, and then exported out of, the country in identical 
quantities. EPA is proposing that an entity does not have to expend 
consumption allowances for transhipped materials if the regulated 
substances are exported within 6 months of import. If a company does 
not tranship HFCs within six months of entry, EPA is proposing that the 
company would have to expend allowances. As explained in the reporting 
section, EPA is proposing that companies notify the Agency when a 
transhipment arrives and leaves the U.S. The intent of this proposal is 
to minimize the risk of illegal imports through the guise of 
transhipments. The United States experienced this method of illegal 
importation during the phaseouts of CFCs and HCFCs. EPA requests 
comment on the length of time a transhipment could reasonably be 
expected to be in the United States and

[[Page 27168]]

whether it is appropriate to allow as little as two months or as much 
as twelve months. EPA also requests comment on other ways to reduce the 
risk of HFC transhipments entering interstate commerce, such as monthly 
reporting (or other reporting frequency) of status while it remains in 
transit; making the bonded warehouse the responsible party for any 
transhipments that enter the market unaccounted for or vented; 
requiring a label; or registration with the certification ID tracking 
system discussed later in this proposal.
    EPA is proposing that allowances issued under the AIM Act be an 
exchange value-weighted number rather than having allowances that are 
specific to each HFC. This approach would align with the approach for 
calculating the baseline envisioned in the AIM Act. Such an approach 
also maintains flexibility in the market if a producer or importer 
decides to switch between regulated substances. This would allow 
entities to efficiently distribute allowances as the market needs and 
may encourage transitions into regulated substances with lower exchange 
values earlier than would happen under the statutorily outlined 
schedule, which could lead to greater environmental and health 
benefits.
    Under this proposed approach, one allowance would be equal to one 
metric ton of exchange value equivalent (MTEVe). Producers and 
importers would multiply the quantity of the HFC they seek to produce 
or import, in kilograms, by its exchange value and then divide by 1,000 
to determine the total number of allowances needed. For example, based 
on the exchange values assigned to regulated substances in the tables 
provided in subsection (c) of the AIM Act, an importer would need to 
expend 1.43 consumption allowances to import one kilogram of HFC-134a. 
Given the variation in exchange values, one would need to expend 
between 0.053 allowances to produce one kg of HFC-152 and 14.8 
allowances to produce one kg of HFC-23. EPA is proposing to adopt the 
table of regulated substances and their corresponding exchange values 
provided in section (c) of the AIM Act into appendix A to the subpart 
established for this rule.
    EPA notes that the exchange values listed in the AIM Act for each 
regulated HFC, and for the CFCs and HCFCs used in the baseline 
calculations, are numerically identical to the 100-year global warming 
potentials (GWPs) of each substance, as given in the Errata to Table 
2.14 of the IPCC's Fourth Assessment Report (AR4) \44\ and Annexes A, 
C, and F of the Montreal Protocol. In practical terms, producers, 
importers, and exporters would be able to use the AR4 GWP of a blend 
that contains only regulated HFCs in determining the amount of EVe 
allowances necessary to produce or import that blend, or more 
precisely, the regulated HFC components contained in the blend. If a 
blend contains components that are not listed as a regulated substance, 
only the components of the blend that are regulated HFCs would be 
included in determining the EVe. As a result, the EVe would be lower 
than the CO2e value for blends that are not limited to 
regulated substances.

    Under CAA Title VI, EPA allocated baseline allowances and annual 
year allowances derived from those company-specific baselines.\45\ EPA 
is proposing to take a different approach for allowances allocated 
under the AIM Act. Specifically, EPA is proposing to only issue 
calendar-year allowances and not create company-specific baseline 
allowances. Under the ODS phaseout, baseline allowances were revisited 
periodically and updated based on transfers between companies. However, 
baseline allowances effectively became ``permanent'' and had value 
across control periods. Companies that stopped producing ODS had the 
ability to continue receiving allowances annually until the phaseout 
date, or could sell their market share to another company by 
transferring their baseline and/or calendar-year allowances. Under the 
AIM Act, EPA is proposing to only issue calendar-year allowances, which 
are only usable in the year they are issued, without the system of 
baseline allowances. This is intended to promote more flexibility in 
future years to adjust approaches and issuances of allowances to a 
dynamic marketplace as opposed to having allocations tied to a singular 
time in the past.

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

B. What are EPA's proposed options for determining allocations?

1. For which years is EPA proposing to issue allowances?
    EPA is planning to issue allowances for 2022 according to the 
framework and procedure established through this rulemaking by October 
1, 2021. EPA intends to provide notice of 2023 allowances by October 1, 
2022, using the framework and procedure to be established in this 
action. Given the AIM Act's deadline of finalizing a rule within 270 
days of enactment, EPA has focused on what can be implemented in a 
short timeframe. EPA recognizes that phasing down a regulated substance 
as required under the AIM Act may have different implications for 
stakeholders than the Agency's past experience with phasing out ODS. To 
allow more time for consideration of these differences, EPA intends to 
seek additional input from stakeholders for later years. As such, EPA 
intends to develop another rule before allowances are allocated for 
calendar year 2024 that may alter the approach and procedure for 
allowance allocations past the year 2023. Given the phasedown schedule 
in the AIM Act, EPA is intending to revisit the initial approach for 
determining allowance allocations established through this rulemaking 
before the 2024 phasedown step to consider whether any changes would be 
appropriate and further build out aspects of this program. In 2024 the 
number of allowances will decrease from 90 percent of baseline to 60 
percent of baseline. Additional analysis of the market--as well as the 
effects of implementing other provisions of the AIM Act--may be 
necessary before issuing allowances for that stepdown.
    EPA welcomes comment on its intention to issue allowances later 
this year only for 2022. EPA is also considering issuing allowances for 
2022 and 2023 by October 1 of this year. EPA's preference for proposing 
to establish a framework but issuing allowances only one year at a time 
provides time for the Agency to solicit and consider other potential 
mechanisms for issuing allowances. The Agency is also uncertain it can 
accurately forecast at this time the full quantity of allowances 
necessary for application-specific uses at this time. As discussed 
further in this section, application-specific allowances must be 
provided from within the general cap of available allowances. Until EPA 
can determine the number of application-specific allowances needed by 
the statutorily identified end users, it cannot know how many 
allowances remain from within the cap for general

[[Page 27169]]

allowances. As a result, EPA is proposing to determine the general pool 
of available allowances, and subsequently provide for individual 
company allocations, each calendar year, as opposed to allocating for 
multiple years at a time.
2. Based on currently available data, which companies is EPA proposing 
to issue allowances to?
    EPA is proposing to issue allowances to companies that produced or 
imported HFCs in 2017, 2018, and/or 2019, and were still active in 
2020. There are two elements within this proposal to discuss: Which 
companies will be eligible to receive allowances and which years of 
operation will be relevant to EPA's determination. Note that this is 
separate but related to how many allowances each company may be 
allocated. How EPA proposes to determine individual allocation amounts 
are discussed separately later.
    EPA proposes that considerations for determining who should receive 
allowances in this initial rulemaking would include providing as 
seamless a transition as possible to a regime where allowances are 
needed to produce and import HFCs, promoting equity, timeliness of 
implementation, and availability of robust data. EPA is proposing to 
issue allowances to active HFC producers and importers operating in 
2020 while providing a set aside for new entrants as a way to meet 
these objectives.
    With regards to production allowances, EPA is proposing to issue 
allowances to companies that produced HFCs in the United States in 
2017, 2018, or 2019 that were also still producing HFCs in 2020. In 
determining the appropriate approach for issuing allowances, EPA seeks 
to avoid issuing production allowances to entities that are unable to 
use them. In particular, EPA would like to avoid issuing allowances to 
companies that no longer produce HFCs or for HFC production capacity 
that has been shut down. EPA also seeks to avoid encouraging the 
creation of new high-GWP HFC production capacity within the United 
States, as that would be contrary to the intended goal of the AIM Act 
to phase down EV-weighted production by 85 percent from the calculated 
baseline figure within 15 years. Production facilities are capital 
intensive and are typically used for long periods of time. The list of 
HFC producers in the United States is included in a memo included in 
the docket (``HFC Production and Consumption Data--Proposed Rule''). As 
noted at an earlier point in this section, EPA is proposing that 
production of HFCs would require expenditure of both production and 
consumption allowances, since production is a component of the AIM 
Act's definition of consumption. As a result, EPA is proposing to issue 
production allowances to those companies that are currently listed as 
HFC producers, as well as any additional companies that can document 
their production of HFCs during the relevant years by the close of the 
comment period listed above in the DATES section of this preamble and 
report to the GHGRP.\46\
---------------------------------------------------------------------------

    \46\ As noted previously, there is no minimum threshold for 
production of HFCs in the GHGRP. People may have previously noticed 
that e-GGRT was limited to submitting and revising GHGRP annual 
reports for years 2015 to 2020. However, EPA has now made available 
a supplemental XLS form for years 2011 to 2014 for HFC producers who 
were subject to the GHGRP, did not submit an annual report for one 
or more of those years, and would now like to submit their supply 
data for those corresponding years. If you have questions, please 
contact the person listed under FOR FURTHER INFORMATION CONTACT.
---------------------------------------------------------------------------

    Consistent with the definition of ``Produce,'' EPA proposes that 
companies receive production allowances based on the total EVe quantity 
produced minus amounts for transformation minus amounts destroyed. EPA 
proposes that consumption allowances be determined for each company 
based on the EVe quantity of HFCs they produced (subtracting out 
transformation and destruction) plus the amount they imported 
(excluding the amount imported for transformation or destruction) minus 
the amount exported. As such, if a company produced HFCs, but then 
exported HFCs, their production allowances would be higher than their 
consumption allowances, assuming the company did not import more HFCs 
than it exported.
    With regards to consumption allowances, EPA is taking a similar 
approach and proposing to issue allowances to companies that produced 
and/or imported HFCs during 2017, 2018, or 2019 that were still active 
in 2020. Similar to the discussion in the baseline section, EPA is 
proposing to use data reported to GHGRP under subpart OO requirements 
to determine companies' import and export activities in 2017-2020. As 
discussed in the section on establishing the baseline, there may be 
companies that imported and exported HFCs in quantities less than 
25,000 MTCO2e and therefore were not required to report to 
the GHGRP. EPA is proposing to issue allowances to importers under the 
25,000 MTCO2e threshold so long as the company provides 
import and export records to EPA, such as Customs forms or bills of 
lading, to document their historic practice consistent with that 
required under subpart OO. EPA will consider all data provided by the 
close of the comment period listed above in the DATES section of this 
preamble. EPA plans to verify any claimed import and export before a 
company is included in the allowance allocation.
    EPA is also proposing to issue allowances at the parent company 
level. If multiple companies and/or facilities that imported HFCs in 
2020 are controlled or owned by the same corporate entity, EPA is 
proposing to issue allowances only to their parent company. If a parent 
company had multiple subsidiaries reporting consumption or production, 
EPA is proposing to base the parent company's allocation on the single 
year where all subsidiaries combined were at their highest level. This 
approach would be administratively easier and improve transparency in 
the market. It would also avoid providing allowances at a higher level 
than is warranted for parent companies that have imported under 
multiple company names. As discussed later, to ensure the integrity of 
the set aside, EPA is proposing that new entrants cannot be a 
subsidiary or otherwise related to a calendar-year allowance holder. 
EPA therefore intends to request corporate ownership information from 
all companies for which allowances may be allocated.
    EPA discusses the question of who could receive allowances in 
greater detail in another section of this proposal. As noted 
previously, EPA intends to revisit the initial approach and procedure 
for determining allowance allocations and for trading for the 2024 and 
later control periods in a subsequent rulemaking after additional 
public input and seeks advanced comment later in this proposal on ideas 
that are currently under consideration.
    EPA is proposing to allocate allowances only to companies that 
produced or imported in 2020, even if they were active in prior years, 
to increase the likelihood that allowances are allocated to companies 
that are active in the HFC market. If a company was not actively 
producing or importing in 2020, EPA would generally presume this means 
the business exited the production and/or import market. Allocating 
allowances to companies no longer producing or importing would be at 
the expense of companies who are still actively invested in HFC 
production and import. However, the Agency is open to consider 
something different from this presumption for individual companies if 
their inactivity

[[Page 27170]]

was due to the COVID-19 pandemic or some other reason, and they have 
documentation to justify such inactivity. If a company wants 
individualized consideration of their market inactivity or activity in 
2020, it must submit comments on this rulemaking containing relevant 
information no later than the end of the comment period.
    EPA recognizes that some importers may be unaware of EPA's 
regulatory activity in this area. EPA is undertaking best efforts to 
develop a comprehensive dataset for purposes of allowance allocation by 
determining the universe of potential importers. EPA is using data 
available through the GHGRP, its February 11, 2021, NODA, stakeholder 
outreach meetings, outreach to trade associations that can inform their 
members, and direct communication with companies that EPA suspects may 
have imported in relevant years that are not captured in the Agency's 
data sources. EPA invites public input on whether there are any other 
means EPA should use to reach this potentially regulated community. EPA 
provides a list of companies that would be eligible for consumption 
allowances under this framework based on currently available data in 
the docket to this rule. EPA is proposing to issue allowances to those 
importers that are currently listed, as well as any additional 
importers that can provide import records to EPA such as Customs forms 
or bills of lading. As noted previously, EPA is also willing to 
consider individual circumstances of businesses that are generally 
active in the HFC import market, but did not import HFCs in 2020, if 
the reason for their inactivity is adequately justified to EPA by the 
close of the comment period.
    For companies that have not previously reported their HFC import 
relevant data, such as through the GHGRP's e-GGRT or in response to the 
February 11, 2021, NODA, they should report to EPA no later than by the 
close of the comment period listed above in the DATES section of this 
preamble if they wish to be eligible for allowances in 2022 and 2023. 
Please contact the person listed under FOR FURTHER INFORMATION CONTACT 
and report your HFC import data for years 2011 through 2020 at https://ghgreporting.epa.gov/ghg/login.do if you have not reported previously. 
EPA needs to verify production and consumption data for companies that 
have not reported previously. Failure to provide data by the stated 
date will mean companies will not receive allowances for 2022 or 2023 
if EPA finalizes the allocation approach as proposed, except for the 
possible availability of the set aside pool for importers not 
previously subject to GHGRP requirements. Any company that was required 
to report to the GHGRP under 40 CFR part 98, but did not do so in 
accordance with the regulatory requirements, should be aware that 
information on potential noncompliance will be forwarded to the 
appropriate EPA enforcement staff.
    As an alternative to looking to data from 2017-2019, EPA is also 
taking comment on issuing allowances only to those companies that 
produced or imported HFCs in 2011-2013 or some other combination of 
years, including all years, between 2011 and 2019, assuming the company 
is still actively producing or importing as of 2020. To develop the 
baseline, EPA has been working to address data gaps and develop a 
fuller understanding of production and import in those years. EPA has 
already provided the public with a list of those companies through a 
Notice of Data Availability in the Federal Register (February 11, 2021; 
86 FR 9059). EPA sees advantages and disadvantages to this approach. 
For example, once companies began to suspect that they might receive 
allowances based on the quantities that they imported, new importers 
may have entered the market with more HFCs than the level of demand. 
2011-2013 is also prior to any anti-dumping and countervailing duties 
(AD/CVD) were finalized (see the memo to the docket on AD/CVD). To 
reward such behavior could harm companies that were already 
participating in the market and/or have invested heavily in developing 
new alternatives to replace HFCs. On the other hand, to exclude all 
newcomers based on the actions of a few could penalize those companies 
that had not entered the market to game their potential for allowances. 
Another factor to consider is when companies may have become aware that 
a phasedown on HFCs was likely and whether companies significantly 
changed their behavior. Reasonably, companies would have been aware 
that the United States may be taking action to phase down HFCs as of 
October 15, 2016, which is when countries agreed to the Kigali 
Amendment. EPA could consider relying on years prior to 2016, or, 
assuming companies that changed behavior did not significantly do so 
between October 15, 2016, and January 1, 2017, EPA could consider years 
prior to 2017. Using years prior to 2016 or 2017 would reflect the 
production and import market prior to this global agreement to phase 
down HFCs. Other proposed considerations surrounding eligibility for 
allowances are discussed in section VII.C of this proposal. EPA is also 
seeking comment on whether the Agency should consider individualized 
circumstances to take into account a company's 2020 data for 
determining allowances for companies that have newly entered the HFC 
import market, for example a company that entered the market or 
acquired another company late in 2019.
3. What is EPA's proposed framework for determining how many allowances 
each company receives?
    This section discusses how EPA proposes to determine how many 
allowances each company receives from the general allocation pool. EPA 
is proposing that under this initial framework, the amount of 
allowances to allocate to producers and importers would be determined 
based on the levels of production and import in 2017-2019. 
Specifically, EPA is proposing to use a company's highest year of 
production or import, on an EVe basis, in those years. Every company's 
highest year amount would then be added together and used to determine 
a percentage market share for each company. EPA proposes to then 
multiply each company's percentage market share with the total amount 
of available calendar-year allowances to determine each company's 
production or consumption allowances. As noted earlier, EPA is 
proposing to establish this process as an initial approach to 
allocating allowances, but intends to revisit this procedure and 
consider whether any changes to it would be appropriate before the 2024 
phasedown step.
    EPA is proposing to choose the highest year over multiple recent 
years, rather than an average or a single year, to account for 
fluctuations in the market. As noted in the previous section, EPA is 
proposing to base the allocation amount on 2017-2019 data, but only 
companies who were actively producing or importing in 2020 would be 
eligible to receive allowances (unless EPA agrees that the company 
merits individualized determination based on comments received through 
this proposed rulemaking process). The Agency could also consider using 
a company's highest market share--a company's exchange value-weighted 
production and consumption relative to the total exchange value-
weighted production and consumption in a given year--over the selected 
years.
    As mentioned previously, EPA is proposing to set aside a small 
amount of allowances out of the total cap for new market entrants. As 
will be discussed in the next section, EPA is also proposing

[[Page 27171]]

to issue allowances for statutorily defined applications according to 
the AIM Act requirements outlined in subsection (e)(4)(B)(iv). 
Subsection (e)(2)(D) of the AIM Act ensures that the total amount of 
allowances issued does not exceed the production and consumption caps, 
even including application-specific allowances.\47\ Therefore, the pool 
of available calendar-year allowances must be determined after the 
amounts for uses in subsection (e)(4)(B)(iv) are determined. These 
calculations would be conducted by EPA to protect company claims of 
CBI. EPA intends to issue allowances to individual companies for 2022 
and release information on the amount of allowances allocated to each 
company publicly no later than October 1, 2021. EPA discusses its 
approach to releasing data in a later section of the proposal. EPA 
intends to issue allowances to individual companies for 2023 and 
release that information publicly no later than October 1, 2022. As 
discussed previously, EPA is proposing this annual process for 
allowance allocations from the general allowance pool because 
application-specific allowance figures may change, and those would need 
to be subtracted from the general pool before EPA determines how many 
allowances are remaining in the general pool to be allocated.
---------------------------------------------------------------------------

    \47\ Under the ODS phaseout, essential uses were exempt from the 
phaseout and were therefore in addition to the amounts allocated. 
Under the AIM Act, application-specific and essential use 
allocations are not exemptions from the cap but rather receive 
priority within the cap. In this NPRM, EPA is not proposing to issue 
essential use allocations.
---------------------------------------------------------------------------

4. What is EPA's proposed framework for issuing allowances?
    This section contains EPA's proposed formula for determining the 
amount of production and consumption allowances to be issued to each 
producer and importer.
    First, EPA would multiply the production and consumption baselines 
by the current phasedown step shown in subsection (e)(2)(C) of the AIM 
Act. EPA is proposing to codify the phasedown steps shown in the table 
in (e)(2)(C) into the regulations at Sec.  84.7. For 2022 and 2023, 
total production and consumption cannot exceed 90 percent of baseline. 
Thus, EPA would multiply each baseline by 0.9 to determine the 
production and consumption caps for those years.
    Second, EPA would subtract from the consumption and production caps 
the amount of application-specific allowances that EPA has determined 
are necessary for the year at issue and the amount of allowances for 
the set aside pool, if EPA finalizes the set aside option proposed. As 
discussed in the next section, EPA is proposing to re-calculate the 
amount of application-specific allowances every year. The remainder is 
the general allowance pool for that year.
    Third, EPA would determine the list of companies that meet the 
framework eligibility criteria for allowances, add up each company's 
EV-weighted high production and consumption amounts in the relevant 
years, and divide each company's high production and consumption amount 
by the total amount to determine what each company's market share would 
be.\48\
---------------------------------------------------------------------------

    \48\ If EPA finalizes an approach where it uses each company's 
highest market share instead of highest production and consumption 
level, the Agency would add up each company's high production and 
consumption market share in the relevant years, and divide each 
company's high production and consumption market share by the total 
amount to determine what each company's revised market share would 
be for allowances available in the year.
---------------------------------------------------------------------------

    Fourth, EPA would multiply each producer or importer's market share 
by the general allowance pool to determine each company's calendar year 
production or consumption allocation amounts. For 2022 and 2023, EPA 
proposes to issue allowances in whole units of MTEVe. This could result 
in rounding issues. Any HFC with an exchange value more than 1,000 
would be issued allowances at less than a kilogram of regulated 
substance. When deducting allowances to account for production or 
import, EPA would round up if the value was greater than or equal to 
0.5 MTEVe and down if below that level. For example, HFC-134a has an 
exchange value of 1,430 and importing one kg would require 1.4 
allowances. However, EPA would only deduct one allowance. Rarely is 
someone importing only one kg of a chemical though, so importing 100 kg 
of HFC-134a, for example, would require 143 allowances and no rounding 
is needed at the total tonnage level. EPA may revisit this approach if 
low-exchange value HFCs become more prevalent and greater precision is 
needed. For example, HFC-152a has an exchange value of 124 and thus the 
import of one kg would require expenditure of 0.1 allowances. EPA is 
taking comment on whether to use less or more granular detail for 
allowance allocations, such as issuing allowances out to one or two 
decimal points.
    Lastly, EPA would then issue by October 1st the list of companies 
receiving production or consumption allowances and application-specific 
allowances as well as the quantities received.
    For allowances for the 2022 calendar year, EPA intends to also 
issue allowances from the set aside pool (see section VI.E. of the 
preamble) by March 31, 2022, if finalized, and distribute any unused 
allowances from the set aside at the same time.
5. What process is EPA proposing to respond to requests for additional 
consumption allowances?
    EPA is proposing a process in Sec.  84.17 to allow a person to 
obtain consumption allowances equivalent to the quantity of newly 
produced (``virgin'') regulated substances that the person exported, 
provided that the substances were originally produced or imported with 
consumption allowances in the same calendar year. Given that the AIM 
Act excludes exports from the definition of ``consumption'' under 
subsection (b)(3), it would be consistent with the Act to essentially 
refund consumption allowances that were expended to import or produce 
regulated substances if those regulated substances were later exported 
from the country. In order to ensure that the statutorily defined 
production and consumption reduction targets are met each year, EPA 
proposes that both the export and the request for additional 
consumption allowances (RACA) must occur in the year in which 
consumption allowances were expended. This approach would prevent a 
producer or importer from over producing or importing high-GWP HFCs 
prior to January 1, 2022, and exporting them to gain additional 
allowances for the initial phasedown years.
    EPA is proposing to require the exporter to submit certain 
information to EPA for the Agency to review before either granting or 
denying the request. This information is needed to verify that the 
regulated substances were in fact exported and would include: (i) The 
identities and addresses of the exporter and the recipient of the 
exports; (ii) the quantity (in kilograms) and names of regulated 
substances exported; (iii) the source of the regulated substances and 
the date purchased; (iv) the date on which, and the port from which, 
the regulated substances were exported from the United States or its 
territories; (v) the country to which the regulated substances were 
exported; (vi) a copy of the bill of lading and the invoice indicating 
the net quantity (in kilograms) of regulated substances shipped and 
documenting the sale of the regulated substances to the purchaser; and 
(vii) a written statement from the producer that the regulated 
substances were produced with expended allowances or a written 
statement from the importer that the

[[Page 27172]]

regulated substances were imported with expended allowances. The full 
list of required information in a request for additional consumption 
allowances can be found at Sec.  84.17. EPA is seeking comment on 
whether additional records should be provided to verify allowances were 
expended as part of the request, at least until the proposed 
certification ID tracking system is established.

C. What are EPA's proposals for the sectors to receive application-
specific allowances?

    This section discusses EPA's proposal to implement subsection 
(e)(4)(B)(iv) of the AIM Act, which directs the Administrator to 
allocate allowances necessary to meet HFC demand for six specified end 
uses, or ``applications.'' The Act directs EPA to issue ``the full 
quantity of allowances necessary, based on projected, current, and 
historical trends.'' The Act also includes a limitation on application-
specific allowances in subsection (e)(4)(B)(iii). This provision 
reinforces the requirement in subsection (e)(2)(A) that a person 
receiving an allocation may not produce or consume a quantity of 
regulated substances that exceeds the number of allowances held by 
them. Further, this reinforces that application-specific allowances are 
to be part of the annual production and consumption caps.
    In order to carry out this statutory direction, EPA is proposing to 
create a third category of allowances called ``application-specific 
allowances'' that can be expended to either produce or import HFCs. EPA 
is proposing to create this third category, and permit the allowance to 
be used for either produced or imported HFCs, because manufacturers of 
products in the statutorily identified applications may not know in 
advance how HFCs will be procured, and EPA wants to promote flexibility 
to ensure that end users receive the ``full quantity of allowances 
necessary.'' In order to ensure that these application-specific 
allowances are provided from within the overall annual production and 
consumption caps, EPA proposes to subtract the amount of application-
specific allowances allocated from both the production and consumption 
general allowance pools.
    This section provides an overview of the applications receiving 
allocations, estimated demand for HFCs in these applications in 2022, 
and EPA's proposed process for issuing and transferring allowances for 
these applications.
1. Overview of the Application-Specific Sectors
    The AIM Act lists six applications in subsection (e)(4)(B)(iv) that 
are to receive the full quantity of allowances needed, based on 
projected, current, and historical trends. As part of the docket to the 
NODA that preceded this proposed rule, EPA released reports 
characterizing the Agency's current understanding of the market for 
five of the six applications (86 FR 9059; February 11, 2021). These 
reports provided data on projected, current, and historical trends for 
the use of HFCs in each sector. EPA received comments on four of the 
five reports (all except defense sprays) noting agreement with 
definitions, consideration of additional applications, and potential 
updated sources for projections of HFC use in certain applications. EPA 
has updated the reports based on the information provided in the 
comments, where applicable, and has included the updated reports in the 
docket to this rule. EPA held a broad stakeholder meeting on February 
25, 2021, related to the AIM Act and the Agency's plans for 
implementation. EPA also held five workshops March 11-12, 2021, related 
to the AIM Act and focused on HFC use for the five applications that 
can receive allocations. Materials from the stakeholder meeting and the 
five workshops are included in the docket to this rule.
Metered Dose Inhalers
    MDIs are handheld pressurized inhalation systems that deliver 
small, precisely measured therapeutic doses of medication directly to 
the airways of a patient. MDIs provide reliable and effective therapy 
for asthma and chronic obstructive pulmonary disease (COPD).
    The pharmaceutical industry historically used CFCs, specifically 
CFC-11, CFC-12, and CFC-114, as a propellant. The pharmaceutical 
industry began introducing HFC propellants (also known as 
hydrofluoroalkanes (HFAs)) for MDIs as replacements for CFCs in the 
mid-1990s, specifically HFC-134a in 1996 followed by HFC-227ea in 2006. 
CFCs continued to be used after their phaseout in MDIs through the 
essential use exemption authorized by the CAA and the Montreal 
Protocol. EPA, along with interagency partners, annually assessed 
demand for CFCs in MDIs and the ability of the pharmaceutical industry 
to transition in order to nominate an exempted amount under the 
Montreal Protocol procedures. The United States stopped making annual 
requests for CFCs for MDIs in 2009. By 2014, the CFC MDI market was 
replaced with HFC MDIs and not-in-kind (NIK) medical inhalers. EPA 
estimates that in 2020, approximately 458 MT of HFC-134a and 78 MT of 
HFC-227ea propellant were contained in MDIs sold in the United States. 
EPA received comments to the market characterizations released with the 
NODA stating that the demand was twice what EPA estimates. The use of 
HFC MDIs in the United States, absent a transition to alternatives, is 
expected to continue as they may be more appropriate for certain 
patients than NIK medical inhalers, such as when the patient requires a 
reliever medication for exacerbations of asthma or other requirements 
(e.g., inhalation strength).
Defense Sprays
    Defense sprays are aerosol-based sprays intended for self-defense 
and include pepper spray and animal sprays. The defense spray industry 
historically used CFCs as a propellant. The defense spray industry 
transitioned to HFC propellants as replacements to CFCs in the mid-
1990s, specifically HFC-134a.
    EPA estimates that in 2020, approximately 125 MT of HFC-134a 
propellant was contained in defense sprays sold in the United States. 
The use of HFC-134a propellant in defense sprays in the United States, 
absent a transition to alternatives, is expected to continue due to its 
non-flammability and physical properties to provide adequate spray 
distance for foam, fog, and vapor defense sprays. Efforts to 
reformulate are underway but aerosol fillers report that alternatives 
have not yet reached their desired specifications.
    EPA is proposing to interpret the AIM Act statutory text to mean 
that EPA provide an allocation for the propellant used in defense 
sprays. EPA is not aware of any other reasonable interpretation, but 
seeks comment on this. EPA's proposed definition states that these 
products use capsaicin and related capsaicinoids (derived from 
oleoresin capsicum) as an irritant. EPA is taking comment on whether 
this definition is inclusive of defense sprays potentially covered by 
subsection (e)(4)(B)(iv) of the AIM Act. One type of defense spray, 
bear spray, is designed to be more potent than pepper sprays designed 
for personal self-defense. EPA regulates bear spray as a pesticide, and 
requires labeling consistent with 40 CFR 156.70 for human hazards 
associated with a product. Labels for bear sprays often contain 
language on hazards to humans & domestic animals similar to the 
following statement: ``DANGER: May cause irreversible eye damage if 
sprayed in the eyes at close range.

[[Page 27173]]

Contact through touching or rubbing eyes may result in substantial but 
temporary eye injury. Strongly irritating to nose and skin. Do not get 
in eyes, on skin or on clothing. Wash thoroughly with soap and water 
after handling. Remove contaminated clothing and wash clothing before 
reuse.'' \49\ Recent news reports indicate there may be use that is 
inconsistent with the label in the product (i.e., use of bear spray on 
people instead of bears).\50\ Bear sprays are not intended for use 
against people, and EPA lacks the authority to regulate or authorize 
such use under the Federal Insecticide, Fungicide and Rodenticide Act. 
EPA is taking comment on whether the Agency should distinguish between 
misuse and proper use when evaluating ``the full quantity of allowances 
necessary'' for such sprays.

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

Structural Composite Preformed Polyurethane Foam
    Structural composite preformed polyurethane (PU) foams are used for 
increased structural integrity and weight reduction in marine and 
trailer applications. The structural composite foam industry 
historically used HCFCs as a foam blowing agent (i.e., HCFC-22) and 
transitioned to HFC blowing agents as replacements for HCFCs in the 
early 2000s, specifically HFC-134a.
    The PU foam and recreational boating industries estimate that in 
2020, structural composite preformed PU foam for marine and trailer 
uses used approximately 28 MT of HFC-134a blowing agent. This specific 
use of HFC-134a blowing agent is expected to continue in the United 
States due to performance issues with alternatives (e.g., lack of 
structural integrity, shrinking). However, it is projected that at some 
point HFC-134a blowing agent will no longer be used in structural 
composite PU foam for marine and trailer use as it is anticipated that 
alternatives will replace HFC-134a throughout the market.
    EPA is proposing to interpret the statutory text to mean that EPA 
provide application-specific allocations for HFC blowing agent used to 
manufacture structural composite preformed polyurethane foam for use in 
manufacturing boats and trailers. EPA is not aware of any other 
reasonable interpretation, but seeks comment on this.
Semiconductors
    The fourth listed application is ``the etching of semiconductor 
material or wafers and the cleaning of chemical vapor deposition 
chambers within the semiconductor manufacturing sector.''
    Semiconductor devices are critical to the functioning of electronic 
equipment. Semiconductor manufacturers use a variety of high-GWP 
fluorinated gases, including HFCs, perfluorocarbons, and sulfur 
hexafluoride, in two main stems of the manufacturing process: Etching, 
also known as plasma etching, and to clean CVD chambers. Depending on 
the complexity of the product, the manufacturing process may require 
upwards of 100 steps utilizing high-GWP gases.
    Semiconductor manufacture uses HFC-23, HFC-32, and HFC-41, 
primarily in etching processes, but also minimally in CVD chamber 
cleaning processes. HFC use in semiconductor manufacturing began in the 
mid-1980s.
    EPA estimates that in 2019, semiconductor fabrication facilities in 
the United States used 43 MT of HFC-23, HFC-32, and HFC-41. Absent the 
uptake of alternatives or use of used HFCs that meet the acceptable 
purity levels, the use of HFCs in semiconductor manufacture is likely 
to continue as HFCs have physical properties that make them well suited 
for this use.
Mission-Critical Military End Uses
    Mission-critical military end uses of HFCs are those uses by an 
agency of the Federal Government responsible for national defense which 
have a direct impact on mission capability as determined by the U.S. 
Department of Defense (DoD), including, but not limited to, uses 
necessary for development, testing, production, training, operation, 
and maintenance of Armed Forces vessels, aircraft, space systems, 
ground vehicles, amphibious vehicles, deployable/expeditionary support 
equipment, munitions, and command and control systems. Based on 
preliminary information, near-term annual EV-weighted use of HFCs in 
mission-critical military end uses is anticipated to be less than 2 
MMTEVe.
On Board Aerospace Fire Suppression
    EPA is proposing to define on board aerospace fire suppression as 
use of a regulated substance in fire suppression equipment used on 
board commercial and general aviation aircraft and space vehicles. This 
definition excludes military aircraft because they are already covered 
under the definition of mission-critical military end uses. On board 
commercial aviation fire suppression systems have historically used 
halons and are installed on mainline and regional passenger and 
freighter aircraft to protect valuable and sensitive assets. Fire 
suppression systems on board aircraft can be divided into two main 
product categories: Total flooding systems and streaming applications; 
currently HFC-236fa and HFC-227ea have replaced halon 1301 in total 
flooding systems in lavatory trash receptacles. Due to weight and 
volume restrictions or penalties (e.g., increased fuel consumption), 
HFCs have not been popularized in other fire suppression systems on 
board aircraft. HFCs have replaced halon 1301 lavatory trash receptacle 
fire suppression systems in new and existing commercial aircraft. EPA 
estimates that in 2020, approximately 0.38 MT of HFC-227ea and 0.30 MT 
of HFC-236fa were installed in new aircraft lavatory fire suppression 
systems. Absent transition to use of alternatives or of used HFCs, the 
use of HFCs in lavatory fire suppression systems is expected to 
continue as new aircraft are sold.
    EPA has previously defined ``space vehicle'' under the Title VI 
regulations at 40 CFR 82.62 as ``a man-made device, either manned or 
unmanned, designed for operation beyond earth's atmosphere. This 
definition includes integral equipment such as models, mock-ups, 
prototypes, molds, jigs, tooling, hardware jackets, and test coupons. 
Also included is auxiliary equipment associated with test, transport, 
and storage, which through contamination can compromise the space 
vehicle performance.'' EPA takes comment on whether space vehicle, as 
defined above, is inclusive of applications that would be considered as 
on board fire suppression. EPA requests relevant information on HFC use 
in these applications.
2. At which point in the application-specific sector production process 
is EPA proposing to issue allowances?
    EPA is requesting comment on which entity should be the recipient 
of application-specific allocations. The Act does not specify who 
should be issued these allowances so the Agency has considered 
allocating either directly to the entity manufacturing the product 
listed in the application (end user) or to the producer or importer who 
supplies the bulk HFC to that entity.
    EPA is proposing to issue application-specific allowances to the 
end user of the HFC who is manufacturing the product listed in 
subsection (e)(4)(B)(iv)

[[Page 27174]]

of the Act or the Department of Defense, in the case of mission-
critical military end uses. EPA has experience under the essential use 
exemption, as implemented under Title VI of the CAA, with issuing 
allowances directly to end users. In that instance, EPA issued 
essential use allowances directly to MDI manufacturers, for example, 
who then conferred those allowances to a company for the production or 
import of a specified regulated substance. One advantage of this system 
was that it ensured that those companies manufacturing MDIs had the 
allowances needed and they could choose which producer or importer they 
would confer their allowances to. This allowed the MDI manufacturers to 
have power to make a competitive choice in a more open market for the 
material and price best suited to their needs, or import the material 
directly themselves. Another advantage was that it helped to ensure 
that the allowances would be expended only for an essential use. 
Because EPA has seen these advantages in its past practice, EPA is 
proposing to use this established process for the application-specific 
allocations. In other words, EPA is proposing to issue application-
specific allocations to the end users for the six statutorily listed 
applications.\51\
---------------------------------------------------------------------------

    \51\ For the purposes of clarity and consistency, any reference 
or mention of EPA issuing application-specific allowances in this 
proposed rulemaking to the end user of the HFC who is manufacturing 
the product excludes mission-critical military end uses. Instead, as 
noted earlier, EPA proposes to directly allocate application-
specific allowances to the Department of Defense for mission-
critical military end uses.
---------------------------------------------------------------------------

    One challenge EPA foresees in issuing application-specific 
allowances to end users is identifying all of the end users. Essential 
use allowances were issued by EPA to companies that had submitted 
applications to the Agency. EPA attempted to identify all of the end 
users for each of the applications listed in subsection (e)(4)(B)(iv) 
of the Act and put this understanding of the market in the 
characterization reports contained in the docket for the NODA. Through 
its NODA, EPA invited potentially affected entities to provide EPA with 
further information or point to existing or suspected data gaps. EPA 
also held five workshops March 11-12, 2021, related to the AIM Act and 
focused on HFC use for five of the six applications (not including 
mission-critical military end uses) that can receive allocations. 
Materials from the five workshops are included in the docket to this 
rule. EPA still through this proposed rulemaking welcomes information 
on whether this is a complete listing of companies. Acknowledging the 
potential limits on its knowledge, EPA also recognizes that it will 
need to provide application-specific allowances on a certain schedule, 
and so proposes to limit the application-specific allocation to 2022 
for those companies that EPA is aware of by the close of the comment 
period listed above in the DATES section of this preamble. In a 
subsequent section, ``What is EPA's Proposed Set Aside Pool of 
Allowances,'' EPA outlines its proposed approaches for setting aside 
additional allowances in the event that other end users are identified 
after the finalization of the rule. EPA recognizes that the preferred 
approach may vary by application depending upon the current methods for 
acquiring HFCs. EPA specifically requests comment from end users in 
these applications and the suppliers of those HFCs.
3. How is EPA proposing to address transfers of application-specific 
allowances?
    EPA is proposing to allow limited transfer of application-specific 
allowances. Specifically, end users within a specific application may 
transfer their allowances only with another end user that will use the 
application-specific allocation for that same application. These could 
be viewed as ``intra-application transfers.'' EPA is proposing to 
prohibit transfers with companies in other applications. Section 
(e)(4)(B)(iv) of the AIM Act states that application-specific 
allowances are provided ``for the exclusive use'' of HFCs ``in an 
application solely for'' those in the statutory list. These transfer 
provisions would help to ensure that, after EPA allocates the full 
quantity of allowances necessary for each application, the full 
quantity stays available to fully supply that application and ensure 
that the application-specific allowances are being exclusively used 
solely for one of the six listed applications. EPA takes comment on 
this proposed approach, which seems consistent with Congress's intent 
in creating this application-specific allocation program.
    EPA is similarly proposing to prohibit the transfer of application-
specific allowances back into the larger market for production and 
consumption allowances. The AIM Act specifies that the allocation is 
for the exclusive use of one of the listed applications. It follows 
that an application-specific allocation could not be transferred to 
produce or import HFCs for a use that was not enumerated. Note that 
there is no restriction on a company who uses HFCs in one of the listed 
applications from acquiring calendar-year allowances from the general 
pool or from purchasing HFCs produced or imported with calendar-year 
production and consumption allowances. In other words, any company that 
uses HFCs in one of the six listed applications has several avenues for 
acquiring HFCs, for example if their actual demand exceeds the amount 
of HFCs covered by their application-specific allowances.
    EPA is proposing similar restrictions to the sale of HFCs acquired 
by expending application-specific allowances. If an application-
specific allowance was expended for the production or import of a 
regulated substance, that substance must be used solely for the 
application it was produced or imported for. EPA is therefore proposing 
to also prohibit the sale of that HFC for use in a different 
application from the one that was intended. This would be an outgrowth 
of the statutory restriction placed on application-specific allowances 
that they be for the exclusive use in the application for which the 
allowance is provided. If an entity could procure HFCs with the 
application-specific allowance, but then freely sell that HFC on the 
open market, that would seem to create a loophole to the restriction 
placed on the use of the application-specific allowance. EPA is 
proposing to allow the intra-application sale of material (i.e., 
amongst companies within the same application), since such intra-
application sale would be consistent with the exclusive use limitation. 
EPA requests comment on the described approach for allowances and HFCs 
acquired with those allowances.
4. What are the criteria EPA is proposing to use for evaluating 
application-specific allowance requests?
    As discussed in section IX.D, EPA is proposing to collect 
information from companies who use HFCs in five of the six applications 
listed in the AIM Act. As noted previously, companies who believe they 
qualify for application-specific allowances should provide data on 
their historical and current use of HFCs in the relevant application to 
EPA by the date the comment period closes on this proposed rule. This 
information should also include a detailed description of how the HFCs 
are used so EPA can determine whether the use is consistent with the 
definition of the application. EPA will use that information to 
determine the full quantity of allowances necessary, based on 
projected, current, and historical trends, for the production or 
consumption of HFCs for the exclusive use of the regulated substance 
for each application, on a company-specific

[[Page 27175]]

basis. For the initial five years after enactment of the AIM Act, EPA 
is proposing to base application-specific allowances on the eligible 
amount of HFCs used by each company requesting such allowances based on 
the higher of the two approaches:

--HFC use by the company in the specific application in the prior year 
multiplied by the average growth rate of use for the company over the 
past three years; or
--HFC use by the company in the specific application in the prior year 
multiplied by the average growth rate of use by all companies 
requesting that type of application-specific allowances (e.g., for 
MDIs) over the past three years.

    EPA is seeking comment on whether the gross domestic product or 
U.S. population growth rates would be appropriate for each of the 
applications, and whether EPA should allow for consideration of 
individual circumstances factually documented to the Agency (e.g., when 
a company projects significant growth due to acquiring another 
company). EPA could also factor in the availability of reclaimed HFCs 
(if suitable), inventory of previously produced and imported HFCs, 
availability of alternatives, or other relevant features. EPA seeks 
comment on this proposed approach and other approaches it could adopt 
to allocate the amount of allowances necessary for each of the 
applications specified in subsection (e)(4)(B)(iv) of the Act. EPA also 
proposes that if future information reveals a company applying for 
application-specific allowances has provided false information, EPA 
reserves the right to revoke allowances, require future retirement of 
allowances at a greater level than the number of application-specific 
allowances allocated, prohibit companies from receiving future 
allowances if there is noncompliance with relevant legal and regulatory 
requirements, and pursue any other appropriate enforcement action.

D. What are EPA's proposed provisions for transferring allowances?

    Subsection (g) of the AIM Act directs EPA to issue rules that 
govern the transfer of production and consumption allowances. EPA is 
proposing to establish transfer provisions in Sec.  84.19 that are 
based in large part on the ODS transfer provisions.
    EPA is proposing to require that the transferor must submit to the 
Administrator a transfer claim setting forth the following: The 
identities and contact information of the transferor and the 
transferee; the type of allowances being transferred (i.e., production 
or consumption allowance); the quantity (in EVe) of allowances being 
transferred; the total cost of allowances transferred; the remaining 
quantity of allowances held by the transferor; and the quantity of the 
offset. For transfers of allowances issued for use in one of the 
applications listed in AIM Act subsection (e)(4)(B)(iv), the transferor 
must also include a signed document from the transferee certifying that 
HFCs produced or imported with these allowances will only be used for 
the same application they were initially allocated for.
    EPA would then certify with records in its possession that the 
transferor has unexpended allowances sufficient to cover the transfer 
claim. Within three working days of receiving a complete transfer 
claim, EPA intends to issue either an objection letter or non-objection 
letter to the transferor and transferee. The transfer cannot proceed 
until EPA issues a non-objection notice. Given reporting to the Agency 
is often after the fact for quarterly activity, EPA is also proposing 
that if after issuance of a non-objection notice the Agency finds that 
the transferor did not have sufficient unexpended allowances to cover 
the claim, the transferor and transferee, where applicable, will be 
held liable for any violations of the regulations of this subpart that 
occur as a result of, or in conjunction with, the improper transfer.
    In cases where EPA issues an objection notice disallowing the 
transfer, either transferor or transferee may file a notice of appeal, 
with supporting reasons, with the relevant Agency official within 10 
working days after receipt of notification that a transfer was 
disallowed. The official may affirm or vacate the disallowance. If no 
appeal is filed electronically by the tenth working day after 
notification, the disallowance shall be final on that day.
    EPA does not intend to broker transactions but rather solely 
confirm that the transferor has sufficient allowances to cover the 
transfer. EPA also proposes to collect information on the price of 
allowances transferred to inform future analyses of rule costs and 
provide additional insight into the market when assessing potential 
regulatory changes and future allocation options.
    Additionally, subsection (g)(2) of the Act requires that the 
regulations ``ensure that the transfers under this subsection will 
result in greater total reductions'' in the production or consumption 
``of regulated substances in each year than would occur during the year 
in the absence of the transfers.'' In other words, the transfer of 
allowances must result in less overall production or consumption than 
would have occurred absent the transfer. The AIM Act also specifies 
that, for transfers between two or more persons, the transferor's 
allowances be reduced by an amount greater than the amount of 
allowances being transferred.
    EPA is proposing to allow transfers of allowances for HFCs provided 
the transferor's remaining allowances are reduced by the amount it 
transferred plus some percentage of the amount transferred (i.e., an 
offset). EPA is proposing that the offset be five percent, and is 
taking comment on a range from one percent to 10 percent. A five 
percent offset would meet the AIM Act statutory directive and provide a 
net environmental benefit without discouraging trading necessary to 
meet market demands.
    EPA analyzed HCFC inter-company transfer data for 2010 through 
2018. The amount of consumption allowances transferred each year ranged 
between five percent and thirty percent of the total number of 
allowances allocated. Thus, a five percent offset would result in a 
reduction in the total allowances in the general pool by 0.25 percent 
to 1.5 percent. Given that small size, EPA's consideration for the size 
of the offset, at this time, pertains more to the effect on an 
individual company and less on the impact to the market overall. As the 
phasedown progresses, EPA may revisit the size of the offset.
    EPA is considering and taking comment on an offset as low as one 
percent and as high as 10 percent. EPA is less inclined to use an 
offset as low as one percent because it would result in the least 
environmental benefit of the proposed options. EPA anticipates that the 
transaction costs resulting from a one percent offset would be minimal. 
Under the class I ODS allowance system, EPA required through rulemaking 
an offset of one percent for any U.S. transfer to achieve the 
reductions in production and consumption required for transfers by 
section 607 of the CAA (60 FR 24970, May 10, 1995). However, the 
phaseout of HCFCs included chemical-specific allowances and required a 
company to exchange allowances for one specific HCFC for another 
specific HCFC (See 68 FR 2820, January 21, 2003). In this rulemaking, 
EPA is proposing to issue allowances on an exchange value-weighted 
basis, which would provide allowance holders with the flexibility to 
determine which HFCs to produce or import without needing to make a 
transfer from one HFC to another HFC. In other words, the Agency is 
proposing to structure the HFC allocation program

[[Page 27176]]

in a way that negates the need to transfer allowances between regulated 
substances, and thus EPA anticipates fewer transfers overall than would 
occur under a chemical-specific phasedown schedule. EPA is also 
considering an offset amount as high as 10 percent to be more 
protective of the environment. This level of offset, however, could 
discourage transfers, resulting in less efficient allocation of 
production and consumption allowances. On the other hand, it may 
encourage the recovery and reclamation of HFCs.
    EPA seeks comment on setting the offset at five percent and is also 
seeking comment on the full range presented. While numerically all the 
percentages would result in a greater total reduction, EPA is 
specifically seeking comment on how to balance the statute's intent of 
providing flexibility through transfers yet doing so in a manner that 
further reduces overall production and consumption, which would result 
in greater environmental protection. This proposal seeks to maximize 
the protection of the environment, while also providing for the ability 
to transfer allowances. However, it may be the case that tolling 
agreements, the fact that most HFCs are used in blends, or other 
factors result in market dynamics for HFC production and import that 
EPA has not considered. Evidence supported by data of harm to the 
market for HFCs or consumer access could be compelling to the Agency.
    EPA is proposing that an offset would apply to all transfers of 
allowances under the AIM Act, including transfers of application-
specific allowances, as subsection (g) appears to apply generally to 
transfers of allowances and does not exempt any allowances from its 
requirements. However, EPA is proposing a one percent offset, but is 
seeking comment on whether a lower offset amount in a range of 0.1 
percent to one percent is more appropriate for the transfer of 
application-specific allowances between companies in a particular 
application. Since the AIM Act states that EPA should provide 
allowances under subsection (e)(4)(B)(iv) of the Act at the levels 
necessary for the statutorily listed applications, a lower transfer 
offset level may be more consistent with the intent of that subsection 
of the AIM Act.
    Note that EPA is proposing that an application-specific allowance 
holder could confer their allowances to an importer or producer, who 
would procure the HFC for the end user, without any offset. EPA does 
not consider the conferral of allowances to be a transfer but rather an 
actualization of the allowance by an end user that is not a producer or 
importer. Because Congress made clear in subsection (e)(4)(B)(iv) of 
the Act that the statutorily listed applications should receive the 
amount of allowances necessary, based on projected, current, and 
historical trends, EPA is proposing to allow these conferrals as part 
of the inherent process of ensuring end users can receive the necessary 
amount of HFCs. As discussed previously, EPA is proposing to define the 
term ``confer,'' to distinguish the concept from ``transfer.''
    EPA welcomes comments on the proposed size of the offset, the 
Agency's assumptions about the likely amount of transfers, and the 
treatment of transfer of allowances issued under subsection 
(e)(4)(B)(iv). EPA seeks comment in a later section of this proposal on 
the applicability of subsection (g) to international transfers.

E. What is EPA's proposed set aside pool of allowances?

    As explained previously, it is reasonable for this initial 
allocation period to largely allocate allowances based on companies' 
practice in the market since 2017, but EPA also acknowledges that this 
approach could exclude companies that have historic practice in the HFC 
market that is not reflected in EPA's existing data and could create a 
market barrier to new market entrants. As a potential way to avoid 
these problems, in addition to the allocation framework and procedure 
outlined in the prior sections, EPA is also proposing to establish a 
single set aside pool of consumption and production allowances. The set 
aside pool as proposed would be available to three groups of companies: 
(1) End users in applications identified for allocations under 
subsection (e)(4)(B)(iv) of the AIM Act that EPA has not recognized in 
the initial allocation of allowances (i.e., the allocation called for 
by October 1, 2021); (2) importers of HFCs in 2017 through 2019 that 
have not been required to report through the GHGRP under 40 CFR part 
98, where EPA does not learn of their past imports in time to issue 
allowances as part of the general pool despite the Agency's best 
efforts; and (3) importers that are new market entrants. EPA is 
proposing that the set aside pool would not be open to companies 
looking to newly enter as producers of HFCs because the Agency does not 
wish to encourage the construction of new HFC production capacity.
    EPA proposes to give priority access to the set aside pool to end 
users in the applications identified in subsection (e)(4)(B)(iv) of the 
Act. EPA acknowledges that not all end users may be aware of EPA's 
regulatory activity in the HFC space, and providing access to the 
proposed set aside pool would ensure end users in the statutorily 
identified applications have the allowances necessary for their 
continued business. EPA proposes to issue allowances to these end users 
only for 2022, recognizing that once aware of the requirements these 
entities will be able to apply for 2023 in the same manner as all other 
application-specific allowance holders.
    After allowances are provided to the (e)(4)(B)(iv) of the Act 
identified applications, EPA would provide allowances from the same set 
aside pool to importers that were not previously required to report to 
GHGRP and were not identified in time to be included in the general 
allowance pool. EPA is not including producers in this stage because 
all HFC producers were required to report to the GHGRP. EPA proposes to 
issue allowances to these previously unidentified importers only for 
2022. EPA's expectation would be that once these importers came into 
the allocation system, these entities will have provided sufficient 
information to receive allocations through the general pool for 2023.
    Finally, EPA is proposing to issue remaining allowances to new 
market entrants seeking to import HFCs in line with the criteria 
outlined later in this subsection. EPA is proposing to provide 
allowances for these new market entrants for both 2022 and 2023. EPA 
proposes to issue the new market entrants allowances for 2022 and 2023 
at the same time in the same quantity for both years. As noted 
elsewhere in this proposal, EPA intends to revisit the overall process 
for allocating allowances for all years past 2024, but would generally 
expect these new market entrants to be able to participate the same as 
historic importers in those later future years.
    EPA acknowledges that creating a set aside pool for new market 
entrants would deviate from historic regulatory practice under CAA 
Title VI, but given that the AIM Act outlines a phasedown, but not 
phaseout, of HFC production and consumption in the United States, in 
this instance it may be appropriate to continue to facilitate 
participation by new market entrants in the HFC import business. EPA 
further proposes to have this set aside pool accessible only to 
businesses that meet the Small Business Administration (SBA) criteria 
for a small business.\52\ During the HCFC

[[Page 27177]]

phaseout, EPA heard from some small businesses that they had been 
unable to source material from domestic suppliers in sufficient 
quantity and/or at a competitive price. EPA's proposal would allow 
small businesses experiencing this challenge to request allowances as a 
new market entrant and import HFCs directly.
---------------------------------------------------------------------------

    \52\ A small business is principally defined and determined 
based on size standards as established by the SBA. The size of a 
small business is defined by either the average number of employees 
over the past 12 months or the average annual receipts over the past 
three years and may vary based on a business's economic activity, or 
industry, under the North American Industry Classification System 
(NAICS). SBA further defines a small business as a for-profit 
business of any legal structure, independently owned and operated, 
not nationally dominant in its field, and physically located and 
operated in the United States or its territories (13 CFR part 121). 
https://ecfr.federalregister.gov/current/title-13/chapter-I/part-121.
---------------------------------------------------------------------------

    If the set aside program is established as outlined in this 
proposal, EPA specifically encourages businesses to apply for set aside 
allowances that may have had particular challenges entering the HFC 
import market due to systemic racism, market-access barriers, or other 
challenges particularly faced by small disadvantaged businesses such as 
minority- and woman-owned small businesses. EPA is mindful of the 
Executive Order on Tackling the Climate Crisis at Home and Abroad (E.O. 
14008), which calls for ``undertaking robust actions to mitigate 
climate change'' and ``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. . . .'' (86 FR 7619). EPA conducted a 
preliminary review of HFC importers and HCFC allowance holders 
(available in the docket). EPA is specifically soliciting comment on 
whether any individuals have experienced structural barriers inhibiting 
their earlier access to the HFC import market, including if there was 
difficulty entering the HFC import market based on criteria such as 
business location, employment of socially or economically disadvantaged 
individuals, or other criteria related to business ownership, employee 
characterization, or business location. The Agency is concerned that 
certain businesses historically have and could continue to experience 
difficulty entering the HFC market due to societal problems, such as 
systemic racism or sexism, and the Agency is interested in collecting 
the information requested in this paragraph to better understand 
whether such issues are affecting entry into this market and to explore 
future opportunities to ensure a more equitable marketplace.
    EPA has reviewed data available to the Agency and determined that 
of the companies that imported HFCs between 2011-2013, eight companies 
were no longer importing HFCs by 2017-2019. It is possible some of 
these companies were still importing under a different name. Nineteen 
companies reported imports of HFCs in 2017-2019 that were not importing 
HFCs in 2011-2013. Again, it is possible that some companies changed 
names, which would reduce this number. With the exceptions of companies 
that were reporting under a different name, EPA would generally view 
these nineteen companies as new market entrants. If EPA establishes a 
set aside allowance pool, it would be appropriate to establish a pool 
that roughly estimates the market shifts EPA has seen over this 
timeframe with additional allowances to accommodate for businesses that 
would have met EPA's criteria to be eligible for general or 
application-specific allowances, but were not identified in time. 
Accordingly, EPA is proposing to establish a set aside pool for new HFC 
importers of a total of five MMTEVe of consumption allowances for 2022, 
but is considering a range up to 15 MMTEVe. Because application-
specific allowances can also function as production allowances, EPA is 
proposing to set aside one MMTEVe of production allowances as well. 
Because EPA anticipates the application-specific end users to be a 
smaller group than the other two groups, EPA is proposing a smaller set 
aside amount. EPA specifically invites comments on the size of the set 
aside for consumption and production allowances.
    As noted previously, EPA proposes that priority access would be 
given to end users that would have been eligible for application-
specific allowances. Such end users would be given an allocation equal 
to what EPA determines that end user would need. For the other 
applicants to the set aside pool, EPA proposes that each would be 
eligible for up to 0.2 MMTEVe in allowances. This value is based on the 
aggregated median quantity of AIM Act-regulated HFC imports (highest of 
2017-2019 for ``new'' importers that did not also import in 2011-2013) 
reported to the GHGRP and scaled based on a common HFC blend, in 
MMTCO2e. EPA seeks comment on whether it should finalize a 
higher limit for companies other than those seeking application-
specific allowances, up to one MMTEVe.
    If there are more applicants for allowances than EPA has set aside, 
EPA proposes to reduce each new market entrant applicant's share on a 
pro rata basis. EPA proposes that allowances received by applicants to 
the set aside pool would be nontransferable because this is the best 
way to ensure that applicants to the set aside pool only request 
allowances they are able to use, and do not simply participate in the 
pool in order to sell the allowances on the open market. If there are 
fewer applicants for allowances such that 2022 allowances remain in the 
pool, EPA proposes to redistribute them to the general pool of existing 
allowance holders on a pro rata basis by March 31, 2022. Alternatively, 
EPA could auction the remaining allowances by March 31, 2022, should it 
finalize this proposed set aside. An auction would promote a more 
dynamic market in which companies could choose to participate if they 
are seeing additional demand for allowances than they were allocated, 
and an auction allows companies to purchase allowances based on what 
the allowance is worth to the company.
    EPA is proposing that companies would have until November 30, 2021, 
to apply to the set aside pool. For entities that fall within the six 
statutorily identified applications in subsection (e)(4)(B)(iv), but 
did not initially receive application-specific allowances from EPA, 
they would apply to EPA in the same manner as they would for the 
application-specific allowances. For all other applicants, in order to 
apply to the set aside pool, EPA proposes that businesses would need to 
demonstrate that they have the ability and intention to enter the HFC 
import market. Specifically, EPA proposes to require applicants to the 
pool to submit an application showing: (1) Name and address of the 
company and the complete ownership of the company (with percentages of 
ownership); (2) whether the company is a woman or minority owned 
business; (3) contact information for the owner of the company; (4) the 
date of incorporation and State in which the company is incorporated 
and State license identifier; (5) a plan for importing HFCs; and (6) a 
prospective foreign exporter that the applicant anticipates working 
with. EPA recognizes that this new entrants pool, if not structured 
appropriately, could result in allowances going to companies that are 
already importing HFCs or are associated with companies that currently 
import HFCs. To prevent fraud and to ensure that these allowances go to 
new entrants in the HFC import business, EPA seeks comment on whether 
there are other data it should

[[Page 27178]]

request. EPA also proposes to limit the set aside to owners of 
companies, not operators or designated agents, and that businesses 
applying to the set aside pool cannot be a subsidiary of or have any 
common ownership stake or familial relationship with another allowance 
holder. EPA also seeks comment on whether it should limit new entrants 
to companies that have not previously imported HFCs. Given the focus of 
the set aside is to allow for companies that seek to newly import HFCs, 
providing allowances to companies who exited the import business seems 
at odds with the general goal of the set aside. If the set aside pool 
is limited to small businesses, applicants would also need 
documentation demonstrating that they meet the SBA criteria for a small 
business. EPA is soliciting comment on this list and invites public 
input on whether any of these items should not be included or if other 
elements should be added. EPA proposes that it would review the 
information provided, conduct follow-up verification as needed, and 
issue allowances to applicants that meet the stated program criteria no 
later than March 31, 2022. EPA also proposes that if future information 
reveals a company has provided false information or has not disclosed 
financial or familial relationships between a new entrant and another 
allowance holder, EPA reserves the right to revoke allowances and 
require the company to retire a greater number of allowances than those 
received through the set aside pool.

F. What is EPA proposing to require for HFC-23 emission controls for 
allowance holders?

    As outlined in the definition section, EPA is proposing that the 
creation of a regulated substance beyond insignificant quantities 
inadvertently or coincidentally created in three specific circumstances 
would be considered ``production.'' As explained in an earlier portion 
of this section, EPA is proposing that such production, whether 
intentional or unintentional, would generally require expenditure of 
production and consumption allowances unless the regulated substance is 
timely destroyed. In this subsection, EPA is outlining a narrowing of 
this general approach particular to HFC-23. Specifically, EPA is 
proposing that HFC-23 must be captured and controlled to a specific 
standard outlined later in this subsection. Entities could either 
destroy the HFC-23 or expend production and consumption allowances to 
capture, refine, and sell it for consumptive uses.
    As noted at the start of this section, the AIM Act provides EPA 
with significant discretion in how to establish an allowance allocation 
system. EPA is proposing to exercise this significant discretion to 
only allow production and consumption allowances to be expended for 
HFC-23 if the HFC-23 is refined and sold for consumptive uses, such as 
in semiconductor etching or refrigeration at very low temperatures. EPA 
understands that currently, some HFC-23 is unintentionally created as a 
byproduct in chemical production processes and vented to the 
atmosphere.\53\ EPA proposes that allowances created through the AIM 
Act cannot be expended for HFC-23 that is vented. An entity that 
creates HFC-23 would need to capture the HFC-23 and could either (1) 
expend production and consumption allowances to sell that HFC-23 for 
consumptive uses or (2) destroy the captured HFC-23 using a technology 
approved by the Administrator.
---------------------------------------------------------------------------

    \53\ See, e.g., ``Fluorinated Greenhouse Gas Emissions and 
Supplies Reported to the GHGRP.'' Epa.gov, Environmental Protection 
Agency, 24 Feb. 2021, www.epa.gov/ghgreporting/fluorinated-greenhouse-gas-emissions-and-supplies-reported-ghgrp#production.
---------------------------------------------------------------------------

    In the alternative, if EPA does not finalize the definition of 
production as proposed, or does not finalize the requirements around 
the exemption from expending allowances for production if regulated 
substances are timely destroyed, EPA proposes to use the significant 
discretion provided in the AIM Act to require that, in order to be 
eligible to receive production allowances under the system created 
through this rulemaking, companies must control, capture, and/or 
destroy HFC-23 byproduct that is created at facilities that produce 
regulated substances and that would otherwise be emitted to a specific 
standard outlined later in this subsection.
    As further support for both EPA's main and alternative proposed 
approaches to addressing HFC-23, EPA notes that HFC-23 is a regulated 
substance under the AIM Act. In the Congressionally provided table in 
subsection (c) of the Act, HFC-23 is assigned the highest exchange 
value of any regulated substance of 14,800, indicating that Congress 
was well aware of the potential impact of this substance and intended 
for it to be regulated on that basis. This exchange value is almost 
5,000 more than the next closest regulated substance (HFC-236fa at 
9,810). EPA has data available through the GHGRP indicating that there 
are emissions of HFC-23 at fewer than four facilities in the country 
that produce other HFCs controlled by the AIM Act.\54\ Because existing 
data suggests that absent control, there may be significant emissions 
of HFC-23 at facilities that produce regulated substances under the AIM 
Act, the AIM Act does not prevent a new entrant from producing HFCs if 
they have the necessary allowances, and because HFC-23 has a 
significantly higher exchange value than any other regulated substance 
under the AIM Act, EPA is proposing to require that an entity that 
creates HFC-23 would need to capture the HFC-23 and could either (1) 
expend production and consumption allowances to sell that HFC-23 for 
consumptive uses or (2) destroy the captured HFC-23 using a technology 
approved by the Administrator. Specifically, EPA is proposing that, no 
later than October 1, 2022, as compared with the amount of chemical 
intentionally produced on a facility line, no more than 0.1 percent of 
HFC-23 created on the line may be emitted. The HFC-23 must be destroyed 
using a technology approved by EPA as outlined in section VII.B. of 
this rulemaking and 40 CFR 84.29(b). As explained further in the 
supporting documentation provided in the docket, EPA is aware that 
these facilities are already taking steps to control, capture, and/or 
destroy their HFC-23 emissions and that current information suggests 
that some facilities are controlling HFC-23 emissions to the proposed 
0.1 percent standard or lower. EPA is also aware of continuous 
improvement projects underway to limit HFC-23 emissions at these 
facilities. Since some facilities have already achieved this standard, 
EPA is proposing that it is reasonable to require facilities to meet 
this standard. EPA acknowledges that some facilities may need to 
install and calibrate new equipment in order to meet this standard, and 
therefore is proposing a compliance date of October 1, 2022.
---------------------------------------------------------------------------

    \54\ There are also reported emissions from other sources 
including from the production of HCFC-22 regulated under CAA Title 
VI. If EPA were to finalize under the alternative interpretation 
proposed, EPA intends to take separate action to address HFC-23 
byproduct emissions from HCFC production.
---------------------------------------------------------------------------

    EPA recognizes that individual circumstances could arise that make 
it impossible for an individual facility to install necessary controls 
by October 1, 2022. Therefore, for companies that can demonstrate to 
EPA that at the relevant facilities, they have taken concrete steps to 
start to improve their HFC-23 control, capture, and destruction (such 
as purchase and installation of necessary equipment), are reporting

[[Page 27179]]

under GHGRP, and provide information to EPA regarding their plans to 
meet the 0.1 percent HFC-23 emissions limit, EPA proposes that the 
Agency may grant a six-month deferral, subject to a one-time additional 
six-month extension. Alternatively, EPA is taking comment (in addition 
to taking comment on all proposals in this section) on whether the 
Agency should grant a one-time, one-year deferral with no possible 
extension. Under either method, companies would need to request such a 
deferral by August 1, 2022. EPA proposes to make a determination on an 
application within 30 days based on whether the company has 
demonstrated good faith efforts to comply with the HFC-23 emissions 
reduction requirement, there are reasons that have necessitated 
compliance deferral, and there are clear plans for the company to come 
into full compliance by the deferred date. EPA intends to publicly 
announce any compliance deferrals granted under this process.
    EPA understands that destruction of HFC-23 may occur both at the 
facility where it is generated (on-site) and may also occur off-site at 
another facility, which may or may not be owned by the same corporate 
entity. In instances where HFC-23 is destroyed off-site, EPA proposes 
that the transportation to and destruction at the off-site facility 
would be considered in calculating compliance with the 0.1 percent 
emissions standard.

VII. What other elements of the AIM Act is EPA addressing in this 
proposed rulemaking?

A. How is EPA proposing to address international trades or transfers of 
HFC allowances?

    Subsection (j) of the AIM Act, titled ``International 
Cooperation,'' addresses the trade or transfer of production allowances 
between entities in the United States and foreign countries.\55\ To 
implement this subsection, EPA must determine whether a country has 
``enacted or otherwise established . . . the same or similar 
requirements or otherwise undertaken commitments regarding the 
production and consumption of regulated substances as are contained 
in'' the AIM Act. Under subsection (j)(4), EPA is required to 
promulgate a rule carrying out this subsection by December 27, 2021, 
and to review that rule at least annually and, if necessary, revise 
it.\56\
---------------------------------------------------------------------------

    \55\ Subsection (j)(1) also addresses exports. In particular, 
after January 1, 2033, it prohibits the export of a regulated 
substance to a person in a foreign country if EPA determines that 
the country has not undertaken certain actions regarding the 
production and consumption of regulated substances. Given the timing 
of this prohibition, EPA does not intend to further address this 
aspect of subsection (j)(1) in this rulemaking.
    \56\ This review would be an internal procedure, but EPA would 
engage in notice and comment rulemaking to revise the regulations.
---------------------------------------------------------------------------

    The statute uses the terms ``trade'' and ``transfer'' with respect 
to allowances in many parts of both subsections (g) and (j). While EPA 
has considered whether Congress intended ``trade'' and ``transfer'' to 
signify different actions with respect to allowances in these 
provisions, neither term is defined in the AIM Act and EPA cannot 
discern a consistent difference in how the terms are used in this 
context. EPA is therefore proposing to interpret them as being used 
interchangeably.
    In most instances, subsections (g) and (j) use ``transfer'' (either 
exclusively or alongside the term ``trade'') to describe the exchange 
of allowances between two entities. Subsection (j) uses the phrase 
``trade or transfer'' throughout the subsection. However, (j)(2) and 
(3) exclusively use ``transfers'' in the paragraph titles, while using 
both ``trade or transfer'' and ``transfer'' in the text of both 
paragraphs. For example, (j)(2) permits the ``trade or transfer of a 
production allowance . . . if, at the time of the transfer'' certain 
conditions are met. There is one instance in subsection (g)(2)(C) where 
the AIM Act references trade alone in requiring that EPA's rule provide 
for ``the trading of consumption allowances in the same manner as is 
applicable [for] the trading of production allowances.'' In all other 
places in subsection (g), the term ``transfer'' is used exclusively, 
for example in (g)(1), which requires EPA to issue a rule that 
``governs the transfer of [production] allowances.'' As Congress uses 
the term ``transfer'' more frequently when only one term appears in 
subsections (g) or (j), EPA is proposing that it would be appropriate 
to use the term ``transfer'' in the AIM Act implementing regulations 
for all instances where the AIM Act contemplates ``trades'' or 
``transfers.'' Hereinafter, EPA refers to ``trade or transfer'' as used 
in subsection (j) of the AIM Act as ``transfers'' for simplicity.
    International transfers of production allowances allow for the 
production of a chemical to be consolidated at fewer plants in order to 
be able to achieve economies of scale as demand shrinks and the HFC 
phasedown progresses. EPA proposes to allow such production transfers 
where the requirements of the AIM Act are met.
    In relevant part, subsection (j)(1) of the Act prohibits any 
company subject to the AIM Act's requirements from transferring a 
production allowance to a company in a foreign country that, as 
determined by EPA, has not established the same or similar requirements 
within a reasonable time from the Act's enactment or otherwise 
undertaken commitments regarding the production and consumption of HFCs 
as are contained in the Act. Subsection (j)(2) describes specific 
conditions that must be satisfied for a company in the United States to 
transfer a production allowance to--or from--a company in a foreign 
country. Such a transfer to a company in a foreign country may occur if 
at the time of the transfer EPA revises the number of production 
allowances for the United States so that the aggregate national 
production of the regulated substance to be transferred is equal to the 
least of three different levels, which are described below. Similarly, 
such a transfer may occur from a company in a foreign country to a 
company in the United States if, at the time of the transfer, EPA finds 
that the foreign country has revised their domestic production limits 
of the regulated substance in the same manner. EPA also has discretion 
under subsection (j)(3) to reduce the United States' production limits 
as a prerequisite to a transfer to a company in a foreign country, or 
to increase the United States' production limits to reflect production 
allowances transferred from a company in a foreign country to a company 
in the United States.
    The proposed regulations that would implement the AIM Act's 
international transfer provisions are structured similarly to the 
provisions governing international transfers under the ODS phaseout 
(see 40 CFR 82.9(c) and 82.18(c)). When a transfer request is 
submitted, EPA is proposing to review whether the foreign country where 
the foreign company is located meets the conditions of subsection 
(j)(1) and is therefore eligible to participate in transfers of 
production allowances to or from the United States.\57\ If the foreign 
country does not meet the conditions in subsection (j)(1), EPA would 
notify the

[[Page 27180]]

requestor in writing that no transfers to or from the country can 
occur.
---------------------------------------------------------------------------

    \57\ In the ODS context, EPA developed a list of countries that 
had domestic regulatory requirements in place regarding the 
production and consumption of ODS. Given the limited number of 
international transfers of production allowances that EPA saw under 
CAA Title VI, EPA does not presently anticipate that a list will be 
necessary to implement these provisions. EPA is thus not proposing 
to establish a list of countries that meet the conditions in (j)(1) 
at this time. EPA may consider whether to implement such a list at a 
future time, such as when the Agency starts implementing the Jan. 1, 
2033, export prohibition in (j)(1).
---------------------------------------------------------------------------

    If EPA determines that the foreign country meets the conditions in 
(j)(1) of the Act, it would consider whether the applicable 
requirements in subsection (j)(2) of the AIM Act are met. For transfers 
to a foreign country, a U.S. company may engage in the transfer under 
subsection (j)(2)(A) if at the time of the transfer EPA revises the 
number of production allowances such that the aggregate national 
production of the regulated substance to be transferred is equal to the 
lessor of three values listed in subsection (j)(2)(A)(i)-(iii):
     The maximum production level permitted under the AIM Act 
for the applicable regulated substance in the year of the international 
transfer minus the production allowances transferred;
     the maximum production level for the applicable regulated 
substances that are allowed under applicable law minus the production 
allowances transferred; or
     the average of the actual national production level of the 
applicable regulated substances for the three years prior to the date 
of the transfer minus the production allowances transferred.
    In relevant part, subsection (j)(2)(A)(i)-(iii) of the AIM Act 
refers to the ``applicable regulated substance'' and ``applicable 
regulated substances,'' such as in the phrase ``the maximum production 
level permitted for the applicable regulated substance in the year of 
the transfer . . . , less the production allowances transferred.'' 
Since EPA is proposing to issue allowances as an exchange value-
weighted amount and not as a chemical-specific quantity, allowance 
holders could use all their allocated production allowances for any one 
chemical. As such, if a company transfers production allowances to a 
foreign country, EPA considers the ``maximum production level permitted 
for the applicable regulated substance in the year of transfer'' to be 
the same as the maximum allocation listed in proposed Sec.  84.7(b), 
which is an exchange value-weighted amount. EPA would take the same 
approach of weighting amounts based on exchange values when considering 
the levels consistent with (j)(2)(A)(ii) and (iii). As the production 
allowances transferred would also be accounted for in terms of the 
exchange value-weighted units, the reduction would be appropriately 
reflected in the total.
    EPA is proposing that the U.S. company seeking to transfer 
allowances (i.e., the ``transferor'') must submit to EPA a signed 
statement requesting that EPA revise the number of production 
allowances consistent with the requirements of subsection (j)(2)(A)(i)-
(iii). EPA would determine which is the lesser of the three values. The 
transferor would also need to submit to EPA information on the contact 
person and foreign country authorizing the transfer; the chemical and 
quantity being transferred; documentation that the foreign country 
possesses the necessary quantity of unexpended production rights; and 
the calendar year for that transfer. EPA seeks comment on whether it 
should additionally require prior approval by a foreign country or some 
other documentation from the foreign country verifying it can increase 
allowable production in the relevant calendar year if EPA approves the 
transfer, or whether an application for such reduction or some other 
official government communication from the foreign country's embassy in 
the United States is sufficient. For these transfers, the allowance 
revisions for the company in the United States would be reflected at 
the individual transferor level.
    In reviewing submissions for transfers to a company in a foreign 
country, EPA would consider whether the transfer and revised production 
limits meet the requirements in subsection (j), as discussed above. EPA 
is also proposing to define other factors the Agency could take into 
account in considering whether to approve such transfers. Under the CAA 
Title VI implementing regulations in 40 CFR part 82, subpart A, EPA has 
the discretion to take factors into account relating to possible 
economic hardships created by a transfer, potential effects on trade, 
potential environmental implications, and the total amount of 
unexpended allowances held by entities in the United States. For the 
AIM Act regulations, EPA sees value in having discretion to consider 
the environmental implications, since there could be an environmental 
benefit or cost associated with the international transfer that could 
influence EPA's decision-making, and the total unexpended allowances 
held by entities in the United States, given EPA would not be able to 
approve a transfer if there were insufficient allowances to transfer, 
and is thus proposing to include these factors among those that could 
be taken into account. The Agency seeks comment on this proposal, and 
on whether and how it should consider other factors, including possible 
economic hardships created by an international transfer (e.g., on U.S. 
employment) and potential effects on trade.
    For transfers from a foreign country, subsection (j)(2)(B) of the 
Act provides that the U.S. company may engage in the transfer if EPA 
finds that the foreign country has revised the domestic production 
limits of the regulated substances in the same manner as for transfers 
by a company in the United States. Accordingly, EPA proposes that the 
company must submit a signed document from an official representative 
in that country's embassy in the United States stating that the 
appropriate authority within that country has revised the domestic 
production limits for that country equal to the least of:
     The maximum production level permitted under the AIM Act 
for the applicable regulated substance in the year of the international 
transfer minus the production allowances transferred;
     the maximum production level for the applicable regulated 
substances that are allowed under applicable law (including the 
country's applicable domestic law) minus the production allowances 
transferred; or
     the average of the country's actual national production 
level of the applicable regulated substances for the three years prior 
to the date of the transfer minus the production allowances 
transferred.
    Consistent with subsection (j)(2)(B) of the Act, these three 
situations are intended to align with the provisions in subsection 
(j)(2)(A)(i)-(iii) of the Act. As noted above, subsection (j)(2)(A)(i)-
(iii) of the AIM Act refers to the ``applicable regulated substance'' 
and ``applicable regulated substances,'' such as in the phrase ``the 
maximum production level permitted for the applicable regulated 
substance in the year of the transfer . . ., less the production 
allowances transferred.'' EPA is proposing that if the country uses an 
exchange value-weighted system similar to what EPA has proposed, this 
phrase should have the same meaning as for transfers from the United 
States to another country. If a foreign country has established 
chemical-specific production levels, this phrase would be interpreted 
to mean the production level for the particular regulated substance 
involved in the transfer. In such a scenario, the production allowances 
transferred would be translated into exchange value-weighted amounts 
for purposes of tracking compliance with obligations under the AIM Act. 
EPA would take the same approach when considering the levels consistent 
with (j)(2)(A)(ii) and (iii). If the foreign country has established a 
different domestic regulatory approach, EPA would need to consider on a 
case-by-case basis how best to review this condition to ensure

[[Page 27181]]

that requirements of the AIM Act are met.
    EPA is proposing that the language in (j)(2)(A)(i) that establishes 
one of the thresholds for determining the appropriate reduction in 
production allowances as the maximum production level permitted ``under 
this section'' for the applicable regulated substance in the year of 
the international transfer be interpreted to restrict international 
transfers from a foreign country to situations in which the country has 
revised their production limits to establish a phasedown schedule at 
least as stringent as that in the AIM Act. As noted above, under 
subsection (j)(2)(B), EPA must find that the country has revised the 
domestic production limits ``in the same manner'' as provided for 
transfers by a company in the United States to a company in a foreign 
country in order for the transfer to occur. One requirement for such 
transfers to a foreign country in (j)(2)(A) is that the number of 
allowances for production under subsection (e)(2) of the Act must be 
revised downward such that national aggregate production is equal to 
the lessor of one of three values, one of which is the maximum 
production level permitted ``under this section'' for the applicable 
regulated substance in the year of the international transfer. Under 
this proposal, subsections (j)(2)(A) and (j)(2)(B) would be read 
together to mean that Congress intended for the international transfer 
provisions only to apply to countries that have revised their 
production limits to establish a phasedown schedule at least as 
stringent as the AIM Act's.
    EPA seeks comment on this proposal and also seeks comment on 
whether those provisions could instead be interpreted to allow 
transfers from foreign countries where the country has satisfied the 
requirements in (j)(1) of the Act and established domestic production 
controls for the 18 HFCs regulated under the AIM Act, even if they are 
on a different phasedown schedule, and revised the maximum production 
limit established under those provisions to account for the transfer. 
The language in (j)(1) would allow for transfers of production 
allowances to a company in a foreign country if EPA has determined that 
the country has put in place ``the same or similar requirements'' as 
are contained in the AIM Act. In relevant part, this language appears 
to allow for transfers (i.e., of allowed production) between the United 
States and countries that have capped their production and are phasing 
down listed HFCs, even if the requirements are not identical. EPA 
specifically solicits comments on how the phrase ``in the same manner 
as provided with respect to transfers by a person in the United States 
under this subsection'' in (j)(2)(B) would be understood under such an 
interpretation.
    For international production allowance transfers to a U.S. company, 
the company would need to submit to EPA a request that includes 
information on the contact person and foreign country authorizing the 
transfer; the chemical and quantity being transferred; the calendar 
year for that transfer; and a signed statement describing whether the 
increased production is intended to allow the company in the United 
States to serve the export market or to serve the U.S. market. This 
information would be helpful to EPA because once the transfer is 
complete, EPA proposes to treat production allowances transferred from 
a foreign country the same way as all other production allowances 
issued by EPA. As such, a production allowance and a consumption 
allowance must be expended for each unit of HFC produced, though if the 
amounts are later exported, the consumption allowances may be 
reimbursed. EPA seeks comment on whether EPA should require prior 
approval by a foreign country or some other commitment from the foreign 
country's embassy in the United States verifying it has decreased 
allowable production before approving of the transfer. Additionally, 
EPA seeks comment on whether it could approve such a transfer if the 
foreign country has committed that it will decrease the allowable 
production after EPA approves but before the transfer occurs. For these 
transfers, any allowance revisions for the company in the United States 
would be reflected at the individual company level. In reviewing 
submissions for transfers from a company in a foreign country, the 
Administrator would consider whether the transfer and revised 
production limits meet the relevant requirements under subsection (j).
    For both transfers from and to foreign countries, EPA, following 
review, would notify the requestor in writing that the appropriate 
production allowances were either granted or deducted and specify the 
affected year(s), provided EPA determines the request meets the 
proposed required conditions. In approving an international transfer, 
EPA would notify the transferor in writing of the appropriate revisions 
to a transferor's allowance balance at the time of approval. For 
transfers from a foreign country, the Administrator would notify the 
requestor in writing that the allowances of that company are revised to 
equal the unexpended production allowances held by the company plus the 
level of allowable production transferred from the foreign country. EPA 
would not adjust available allowances until the foreign country's 
representative had confirmed the appropriate number of allowances were 
deducted in the foreign country.
    For a transfer to a foreign country, the AIM Act does not limit the 
quantity of production allowances that may be transferred. EPA is 
seeking comment on whether to include a provision like the one used 
under the implementing regulations for international transfers for ODS 
under CAA Title VI giving the Administrator the option to disapprove 
the proposed transfer if the transfer is not consistent with domestic 
policy. EPA also seeks comment on what policies might be relevant in 
this context. Additionally, EPA is proposing that it would deny the 
transfer if the transferor did not possess sufficient allowances to 
permit the necessary reduction in aggregate domestic production to be 
reflected in the transferor's revised production limits.
    If EPA approves the proposed transfer, EPA would establish revised 
production limits for the transferor so that the aggregate national 
production permitted reflects the effect of the transfer of production 
allowances. In certain circumstances, following a transfer of 
allowances to another country, the AIM Act requires that the aggregate 
national U.S. production of the HFC to be transferred be reduced by an 
additional amount beyond a simple deduction of the number of allowances 
transferred to another country. For instance, if the average actual 
U.S. production during the three-year period prior to the date of the 
transfer is less than the total allowable U.S. production for that 
substance under Sec.  84.7(b), then by the time of the transfer, U.S. 
production would need to be revised downward to equal the three-year 
average minus the amount transferred. This additional reduction would 
also need to be reflected in the revised production limit.
    EPA requests comment on whether there are any other scenarios where 
a greater reduction would be needed. In such circumstances, EPA is 
proposing to conclude that it would be appropriate for the required 
reduction in U.S. production to be allocated among all the transferors 
participating in international transfers in the same calendar year in 
proportion to the number of allowances transferred by each entity. This 
approach would be fair, as it treats every company equally based on the 
total number of allowances transferred. To

[[Page 27182]]

ensure EPA does not need to revise allowances if companies submit their 
requests at different times, e.g., one company submits a request by 
February 1 and another on September 1, EPA is proposing that all 
requests for international transfers of production allowances be 
submitted by October 1 of the year prior to the year the transferred 
allowances would be useable. If there is only one transferor, the 
reduction would be applied exclusively to that company. EPA would 
notify each transferor of the revised production limit before January 1 
and the allowances would be useable as of January 1 for the full 
calendar year. The transfers would be deemed to occur as of January 1, 
the date the transferor's production limit is revised and the 
allowances are useable, for purposes of determining the three-year 
period for purposes of this analysis. The transferor would then be able 
to make timely market decisions with the remaining production 
allowances. EPA would rely upon the three most recent calendar years' 
worth of data. For example, if a request were submitted by October 1, 
2022, EPA would rely upon data from January 1, 2019, through December 
31, 2021, to determine the average of the actual national production 
level over the last three years (as specified in subsection 
(j)(2)(A)(iii)). While the AIM Act states the Agency should use the 
average production level for the ``three-year period ending on the date 
of the transfer,'' such data for the year ending on the date of 
transfer would generally not be reported until 45 days after the end of 
the quarter, and then would need to be reviewed by EPA for accuracy. 
Further, the timing for the availability and/or release of another 
country's data is unknown. Thus, EPA is proposing that it is reasonable 
to implement this provision through the three most recent calendar 
years' worth of data.
    EPA requests comments on this proposal, including the proposed 
dates for submission of requests and approvals of the transfers, and 
additionally solicits comment on whether it should use a different 
three-year period for purposes of this analysis, such as based on the 
three-year period starting from the quarter closest to the date of the 
transfer that has data reviewed for accuracy by EPA. For example, EPA 
requests comments on an alternative under which if requests were 
submitted by December 31, 2022, they would be approved by March 1, 
2023, and useable for the rest of that year, and the three-year period 
would be evaluated from October 1, 2019, to September 30, 2022. EPA 
further requests comments on how it should proceed if information on 
the actual national production level for the applicable regulated 
substances is not available for all of the relevant three-year period. 
EPA also requests comment on whether rather than grouping the requests 
together, it should alternatively allow requests for international 
transfers to be submitted individually on a rolling basis over the 
year, evaluate them separately as they come in, and if any request 
happens to trigger a need to reduce the aggregate national U.S. 
production by an additional amount beyond a simple deduction of the 
number of allowances transferred, that additional amount would be 
applied exclusively to that requestor's balance.
    EPA is proposing the following method to determine the transferor's 
balance of production allowances after a transfer to a company in a 
foreign country: The Administrator would determine which of the values 
under (j)(2)(A) of the Act leads to the lowest value and adjust 
allowance balance(s) accordingly. EPA requests comment on the proposed 
provisions and method used to calculate revised production limits for 
those wishing to transfer production allowances internationally. EPA 
also requests comment on its proposal if more than one company 
transfers production of an HFC to a foreign country or countries in one 
year, and on possible alternative methods to calculate these revised 
production limits.
    Given the discussion at the start of this section explaining how 
``transfers'' is used in (g) and (j) of the Act, and that EPA is 
proposing to interpret references to that term as synonymous with 
references to trade, the Agency is also proposing to apply the 
requirement in subsection (g)(2) to international transfers. Subsection 
(g)(2) of the Act specifies that EPA's regulations shall ensure that 
transfers ``will result in greater total reductions in the production 
of regulated substances in each year than would occur during the year 
in the absence of the transfer.'' The Agency is proposing to conclude 
that it is reasonable to view (g)(2) of the Act as applying equally to 
all transfers. This is consistent with the requirement under (g)(1) 
that EPA promulgate a regulation that ``governs the transfer of 
allowances for the production of regulated substances under subsection 
(e)(3)(A)'' of the Act. As the international transfers under (j)(2) 
would affect the production allowances issued under subsection 
(e)(3)(A), it would be reasonable to apply those requirements to 
international transfers as well. This approach would also result in an 
additional benefit for the environment than would occur absent the 
transfer, consistent with (g)(2). See the discussion earlier in this 
proposal for the proposed offset that would be associated with 
transfers generally, including international transfers. EPA seeks 
comment on this proposal, as well as on whether international transfers 
should have the same offset level as all other transfers or if a level 
at the lower or higher end of the proposed one to 10 percent range is 
more appropriate. For comments addressing this issue, EPA requests that 
they include the commenter's views, if any, both on what level the 
Agency should use as an offset for international transfers and, if at a 
different level than other offsets, why a different level is warranted.

B. How is EPA proposing to address destruction of regulated HFCs?

1. Which destruction technologies is EPA proposing to approve for the 
destruction of regulated HFCs?
    The AIM Act in subsection (b)(7) defines the term produce to 
exclude the destruction of HFCs if the destruction occurs through use 
of a technology approved by the Administrator. This section proposes a 
list of destruction technologies that would be considered approved for 
purposes of the AIM Act.
    Many of the destruction technologies previously approved by EPA to 
destroy ODS have also been found capable of destroying HFCs to a 
minimum destruction and removal efficiency (DRE) of 99.99 percent.\58\ 
EPA proposes to find that technologies that destroy HFCs to a DRE of 
99.99 percent are appropriate to list for approval under the AIM Act. 
There are three broad categories of destruction technologies: Thermal 
oxidation (incineration), plasma, and conversion (other, non-
incineration) technologies. There are twelve destruction technologies 
capable of destroying HFCs other than HFC-23 to a DRE of 99.99 percent, 
and eight technologies capable of destroying HFC-23 to a DRE of 99.99 
percent.
---------------------------------------------------------------------------

    \58\ 2018 TEAP Report, Volume 2: Decision XXIX/4 TEAP Task Force 
Report on Destruction Technologies for Controlled Substances. March 
15, 2021. https://ozone.unep.org/sites/default/files/2019-04/TEAP-DecXXIX4-TF-Report-April2018.pdf.
---------------------------------------------------------------------------

    The 12 technologies that destroy HFCs other than HFC-23 to a DRE of 
99.99 percent are:
     Incineration (6 technologies): Cement kilns, gaseous/fume 
oxidation, liquid injection incineration, porous thermal reactor, 
reactor cracking, and rotary kiln incineration.
     Plasma (3): Argon plasma arc, nitrogen plasma arc, and 
portable plasma arc.

[[Page 27183]]

     Conversion (3): Chemical reaction with hydrogen 
(H2) and CO2, gas phase catalytic de-
halogenation, and superheated steam reactor.

The eight technologies that destroy HFC-23 to a DRE of 99.99 percent 
are:

     Incineration (4): Gaseous/fume oxidation, liquid injection 
incineration, reactor cracking, and rotary kiln incineration.
     Plasma (2): Argon plasma arc and nitrogen plasma arc.
     Conversion (2): Chemical reaction with H2 and 
CO2 and superheated steam reactor.
    EPA proposes creating two lists of approved destruction 
technologies--one for HFC-23, which is more difficult to destroy, and 
one for all other regulated substances. These technologies provide a 
variety of technological options for the destruction of HFCs and are 
capable of either destroying HFCs at a DRE of at least 99.99 percent or 
converting them into non-regulated substances.
    EPA solicits comment on whether the list of destruction 
technologies is appropriate, whether any additional destruction 
technology should be considered, and notes that the Agency intends to 
consider adding additional destruction processes to the list of 
approved destruction technologies in the future as further technologies 
are developed. EPA also solicits comment on whether it should only 
establish one list containing only the eight technologies that can 
destroy HFC-23. This would ensure the technologies can adequately 
destroy the HFC with the highest exchange value. EPA is concerned that 
HFC-23 could be mistakenly taken to a destruction facility that is 
incapable of destroying the compound, such as when HFC-23 is contained 
in a mixture of other HFCs. This could be avoided by approving only 
destruction technologies that can destroy all HFCs.

VIII. What enforcement and compliance provisions is EPA proposing?

    Based on EPA's experience with the ODS phaseout in the United 
States,\59\ the global experience phasing out ODS,\60\ and the recent 
experiences in countries that have already begun phasing down HFCs,\61\ 
the incentive to illegally trade HFCs will likely increase as HFC 
production and consumption become regulated and as allowances that 
authorize import and production of HFCs decline. It is EPA's intent to 
establish mechanisms that discourage and prevent illegal production, 
import, and subsequent sales of illegally produced or imported HFCs. 
These proposals are designed, when taken together, to deter 
noncompliance, incentivize future compliance, and ensure that companies 
that are complying with statutory and regulatory obligations are not 
put at a competitive disadvantage.

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

    In developing this proposal, EPA reviewed in detail the challenges 
faced by the European Union (EU) in preventing illegal imports of HFCs. 
Assessments available in the docket from HFC producers, industry 
associations, and environmental non-governmental organizations (NGOs) 
provide evidence of significant non-compliance with the EU F-gas rule 
(Regulation (EU) No 517/2014), which establishes a schedule to phase 
down HFC production and consumption over time, similar in concept to 
the HFC phasedown in the AIM Act albeit on a different schedule. These 
assessments suggest that noncompliance in the EU occurs primarily 
through illegal imports, which can be grouped into two categories: (1) 
``Open smuggling'' through the normal customs channels (e.g., correct 
commodity codes without proper allowances to do so) and, (2) 
``traditional smuggling'' where the importer seeks to avoid the typical 
customs channels altogether or where HFCs are concealed (e.g., 
mislabeling). Reports show significant awareness in the industry of 
illegal activity. A 2019 report by the Environmental Investigation 
Agency (EIA) \62\ provided results of surveys conducted with industry 
stakeholders in Europe. More than 80 percent of companies surveyed were 
aware of or suspected illegal HFC trade and 72 percent had seen or been 
offered refrigerants in disposable cylinders--a common feature of 
illegally imported HFCs despite the EU requirement that HFCs be sold in 
refillable containers.
---------------------------------------------------------------------------

    \62\ ``Doors Wide Open.'' Eia-International.org, Environmental 
Investigation Agency, Apr. 2019, https://reports.eia-international.org/doorswideopen.
---------------------------------------------------------------------------

    The review of European customs data presented in the EIA report and 
others back up this perception. EIA found that ``bulk HFC imports in 
2018 were too high for compliance with the 2018 quota.'' \63\ EIA 
estimated that the amount of HFCs placed on the market in 2018 could be 
16.3 MMTCO2e (or 16 percent) above the quota amount (i.e., 
the amount allocated) through ``open smuggling of HFCs (i.e. imports 
openly shipped through customs without quota).'' \64\ Honeywell 
estimated that illegal imports were equivalent to more than five 
percent of the total CO2-weighted quota in 2015.\65\ The law 
firm King & Spaulding, on behalf of the Alliance for Responsible 
Atmospheric Policy, found that reported imports to European customs 
officials exceeded the quota amount by 16 percent in 2019 and 33 
percent in 2020.\66\ The European FluoroCarbons Technical Committee 
(EFCTC) cited analysis of customs records done by Oxera, who found a 
significant disagreement in trade data on HFCs shipped from China to 
the EU. Oxera created a database using data from the EU statistics 
agency Eurostat, the United Nations' trading statistics database 
Comtrade, and Chinese export data to calculate the amount of HFCs that 
was illegally imported (above the quota amount). They found that what 
was reported as exported from China alone was 16 percent higher than 
the amounts reported as imported into the

[[Page 27184]]

EU during 2016, six percent higher in 2017, and 21 percent higher in 
2018.\67\

    These reports also indicate the likelihood of more covert smuggling 
activity, though the scale is not fully known. Reported seizures of 
illegally imported material in EU member states between 2018 and 2020 
range from a few cylinders to more than 76 MT of HFCs.\68\ These 
reports show significant growth in legal HFC imports from China into 
countries neighboring the EU. King & Spaulding cites a 2020 report by 
Oxera showing a 40 percent increase in HFC exports from China to EU 
neighbor countries from 2016-2018.\69\ They note the dramatic increase 
in 2018 coincides with a stepdown under the EU's HFC allocation 
program, and that the increase in legal imports to neighbor countries 
could be associated with smuggling HFCs into the EU. They also ``noted 
that various reports found smuggled imports [into the EU] were 20 to 
30% of the quota.'' \70\

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

    While not definitive, the reports note this growth may be because 
the HFCs are being illegally imported into the EU through neighboring 
countries, such as with fraudulent import declarations, disguised as 
something else, or through shipment in hidden compartments. The reports 
also note that illegally imported HFCs that are caught are shipped 
primarily in disposable cylinders. King & Spaulding cites a report from 
an international investigation agency called Kroll, which was hired by 
the EFCTC to investigate HFC trade in the EU. In addition to finding 
that illegal HFCs travel through EU neighbor countries, illegal 
shipments are often sold through online market platforms or arrive 
through misdirected transhipments, allocation abuse, open smuggling, 
and counterfeit material.\71\

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

    In summary, there is significant evidence of noncompliance with HFC 
quotas in the EU, which suggests that similar attempts will be made to 
evade legal requirements in the United States. By comparison, if the 
United States were to see similar noncompliance of five to 33 percent 
of the total U.S. allocation, that would equate to 13-90 MMTEVe of 
additional consumption than should happen under the statutorily 
provided phasedown step for 2022 alone with accompanying long term 
emissions and environmental and public health costs associated with 
that level of consumption. This level of noncompliance would put 
businesses complying with regulatory requirements at a competitive 
disadvantage and could inhibit companies from investing in research and 
development to identify new alternatives. In addition, illegal imports 
of HFCs have consequences for other U.S. agencies, such as Customs and 
Border Protection who collect duties on imports of HFCs.
    Consistent with the documented experience in the EU, EPA has also 
seen situations where material that appears to be illegally imported is 
advertised as one chemical, but the contents of the container are 
something different. EPA recently identified imports of small cans that 
were advertised as ``Cool Penguin F-12'' (or CFC-12) in small cans for 
use in motor vehicle air conditioners.\72\ While the cans contained 
some CFC-12, they also contained an inconsistent mixture of numerous 
other chemicals, including R-40 (chloromethane) which is toxic and has 
the potential to explode. Given this experience with imports of 
fluorocarbons that are mislabeled, there are consumer and worker safety 
concerns.

Alert: Online Sales of Cool Penguin F-12 in Action (November/

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

    Through the proposed requirements that follow, EPA is proposing to 
put in place strong enforcement and compliance measures at the outset 
of this new regulatory program developed pursuant to AIM Act authority 
to prevent or identify illegal activity in the United States and ensure 
compliance with the obligations under the AIM Act. Failure to do so 
could significantly harm the environment, the U.S. economy, and 
consumer and worker safety.
    The experience in the EU and the grounded belief that a similar 
scenario could come to fruition in the United States calls for robust 
enforcement, compliance, and transparency provisions to ensure EPA can 
meet the statutory directive in AIM Act subsection (e)(2)(B) that ``the 
Administrator shall ensure that the annual quantity of all regulated 
substances produced or consumed in the United States does not exceed'' 
the levels prescribed in the AIM Act. EPA understands this directive, 
as well as the prescriptive schedule established in subsection (e) of 
the AIM Act and the inclusion of application-specific allowances within 
the overall cap, as indications that Congress intended for the 
statutorily required reductions in HFC consumption and production to 
occur. EPA is accordingly proposing comprehensive compliance and 
enforcement measures to help ensure that it can implement the allowance 
program so that it achieves these reductions.
    EPA is proposing a multifaceted approach to prevent and identify 
noncompliance in order 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. Each element is intended to deter illegal 
activity and address such activity when it is identified. The key 
components of this proposal include:
     Administrative consequences to deter noncompliance and 
create pathways to address the impacts of noncompliance;
     Packaging (including requiring use of refillable 
cylinders) and labeling requirements;
     Increased oversight of imports including requiring 
consumption allowances to import heels and U.S. goods returned, 
petitioning to import regulated substances for transformation or 
destruction processes, reporting of transhipments, and prohibiting the 
import of virgin HFCs for disposal.
     Establishment of a comprehensive certification ID tracking 
system using QR codes or similar digital technology to track the 
movement of HFCs through commerce, including requiring anyone that 
introduces into interstate commerce or sells HFCs to be registered in 
the system;
     Recordkeeping and reporting;
     Third-party auditing; and
     Data transparency.
    EPA intends to work with CBP to institute an automated electronic 
mechanism to check in real-time if an importer has sufficient 
allowances for a particular shipment. EPA and CBP have established 
working relationships regarding the imports of various goods subject to 
domestic regulation, including ODS. EPA intends to modify the Agency's 
electronic database

[[Page 27185]]

monitoring HFC allowances such that the most current available 
information is up to date to allow for real-time or near real-time 
electronic confirmation by CBP of whether a company seeking to import 
HFCs is an allowance holder and has sufficient allowances for that 
specific import.

A. What are the proposed administrative consequences available to EPA 
with respect to allowances?

    As noted elsewhere in this rulemaking, production allowances, 
consumption allowances, and application-specific allowances do not 
constitute property rights. The AIM Act gives the Administrator 
significant authority to determine an appropriate allowance system, 
which EPA proposes would include the authority to retire, revoke, or 
withhold allowances at the discretion of the Administrator under 
certain defined circumstances. For clarity and consistency, EPA intends 
to treat each of these potential consequences in the following manner:
     A retired allowance would be one that EPA would have 
otherwise issued to an entity for the next calendar year, but instead, 
may not be expended in the following calendar year by that entity, nor 
be transferred to any other entity. A retired allowance would 
effectively expire unused in the next calendar year. If an entity does 
not have sufficient allowances to retire, it would need to acquire 
those allowances (e.g., through a transfer) and retire them.
     A revoked allowance would be one that EPA rescinds after 
issuance to an entity. EPA proposes that any unexpended allowances held 
by an entity may be revoked as described below and then redistributed 
on a pro rata basis to the general pool.
     A withheld allowance would be one that EPA would have 
otherwise issued to that entity for the next calendar year, but 
instead, is redistributed on a pro rata basis to the general pool. 
Similar to a retired allowance, the entity that would have received the 
allowance would not be able to expend it nor transfer it; however, 
unlike a retired allowance which would expire unused, an allowance that 
is withheld from an entity would be redistributed.
    EPA also proposes that there may be circumstances where the 
potential administrative consequence could be a ban on a company and/or 
its owner(s) receiving future allowances. In this scenario, EPA 
proposes that the company and/or its owner(s) would not be eligible to 
receive or obtain allowances by way of allocation or transfer, and such 
a ban would effectively render the company and/or owner(s) unable to 
produce or import HFCs regulated under the AIM Act. If EPA were to ban 
the company, EPA proposes that any allowances that the company has 
already received would be revoked, and any allowances that the company 
might have otherwise received in the future would be withheld and 
redistributed on a pro rata basis to the general pool. If EPA were to 
ban the owner(s), EPA proposes that any allowances that the owner(s) 
has already received, either through the company at fault or a 
different company, would be revoked, and any allowances that the 
owner(s) might have otherwise received in the future, either through 
the company at fault or a different company, would be withheld and 
redistributed on a pro rata basis to the general pool. EPA proposes 
this potential consequence both as a deterrent to prevent illegal 
production and import, but also to ensure that, if illegal activity 
occurs, bad actors are removed from the HFC allocation system such that 
EPA can ensure production and consumption caps are met moving forward 
in line with the AIM Act's Congressional directive.
    These proposed administrative consequences for allowances are not 
intended to supplant or replace any enforcement action taken under the 
AIM Act. Instead, such consequences would be in addition to any 
applicable enforcement action.

B. What practices could warrant EPA's proposed administrative action 
for allowances?

    EPA has identified the following types of practices that could 
warrant the Agency exercising its discretion to levy administrative 
consequences for allowances: falsifying information or data; not 
disclosing financial conflicts of interest or familial relationships in 
certain circumstances; noncompliance with the AIM Act or proposed 
prohibitions under Sec.  84.5; and noncompliance with Department of 
Commerce (DoC) and CBP HFC trade provisions. Discussion of each of 
these categories as well as EPA's proposal regarding what 
administrative consequences may be taken for allowances follows. Any 
administrative action taken is not intended to supplant or replace any 
enforcement action taken under the AIM Act. Instead, such consequences 
would be in addition to any applicable enforcement action. In all 
cases, EPA could also ban a company and its owner(s) receiving future 
allowances for such action, depending on the severity of the 
noncompliance.
1. Falsifying or Failing To Disclose Relevant Information
    As discussed previously in this rulemaking and detailed here, EPA 
is proposing that falsifying information with respect to application-
specific allowances may warrant one or more administrative consequences 
for allowances. Specifically for application-specific allowances, EPA 
proposes that if future information reveals a company applying for 
application-specific allowances has provided false information, EPA 
reserves the right to revoke allowances and/or require future 
retirement of allowances at a greater level than the number of 
application-specific allowances allocated.
    Falsifying or failing to disclose relevant information as described 
in the preamble section, ``What is EPA's Proposed Set Aside Pool of 
Allowances'' could warrant EPA exercising the right to revoke 
allowances and requiring the company to retire a greater number of 
allowances than those received through the set aside pool. If the 
company receiving set aside allowances is later determined to be 
financially connected or have a familial relationship with another 
company receiving set aside allowances or another allowance holder, EPA 
proposes to also have the ability to apply these provisions regarding 
revoking, withholding, and retiring allowances (with a premium as 
discussed elsewhere in this proposal), as well as banning all the 
companies and owner(s) involved from receiving future allowances.
2. Compliance With the AIM Act
    EPA is proposing that the Agency could revoke or withhold 
allowances from an entity that has been found, through a concluded 
enforcement action, to have unlawfully produced or imported, or 
attempted to unlawfully produce or import, HFCs. EPA is also proposing 
that it could ban a company and its owner(s) receiving future 
allowances for such action, depending on the severity of noncompliance.
    EPA is also proposing that if an allowance holder produces or 
imports, or attempts to produce or import, HFCs in excess of their 
allowances under the AIM Act, such as if an import arrives at a port 
without the appropriate allowances or there is production at a facility 
whose parent company does not have allowances, the allowance holder 
would be required to retire that amount in the following year. This 
administrative action would not be contingent on a concluded 
enforcement case. Instead it would be based on information available to 
EPA, such as

[[Page 27186]]

allowance availability at the time of production or import, or evidence 
from the QR code tracking system that a company is selling material 
that was produced or imported without allowances. EPA would have 
discretion to add a range of premiums based on the case specific 
factors such as the egregiousness of the violation and whether there 
are repeated violations. EPA is proposing a range of between 20 percent 
and 200 percent and welcomes comment on this range. In cases where the 
amount required to be retired in the following year exceeds the 
allowances held by the importing entity for the next year, EPA proposes 
that the allowance holder may be subject to complete revocation or 
retirement of its HFC allowances, or may not be issued allowances in 
future years or may receive a reduced allocation.
    EPA is proposing these potential administrative consequences to 
deter illegal production and import. Illegal production and import 
undermine EPA's ability to meet the AIM Act requirement that EPA ensure 
that the United States' HFC production and consumption do not exceed 
the statutorily defined cap. The proposal to retire allowances also 
ensures there is an environmental benefit to account for noncompliance 
that could result in production and/or consumption above the permitted 
levels.
3. Violation of Department of Commerce and Customs and Border 
Protection Trade Provisions
    EPA is aware of potential concerns with allocating allowances to 
entities that DoC has determined are dumping HFCs onto the U.S. market. 
Dumping refers to ``when a foreign producer sells a product in the 
United States at a price that is below that producer's sales price in 
the country of origin, (``home market''), or at a price that is lower 
than the cost of production.'' \73\ Foreign governments may subsidize 
industries by providing financial assistance to benefit the production, 
manufacture, or exportation of goods, thereby unfairly undercutting 
domestic producers. The DoC attempts to eliminate the unfair pricing or 
subsidies or the injury caused by such imports by imposing additional 
duties, termed Anti-Dumping/Countervailing Duties (AD/CVD). The amount 
of subsidies the foreign producer receives from the government is the 
basis for the subsidy rate by which the subsidy is offset, or 
``countervailed,'' through these higher import duties. Anti-dumping and 
countervailing subsidy duties are two ways that the U.S. government 
addresses dumping and unfair foreign subsidies. The U.S. government can 
require that foreign companies involved in dumping and/or benefitting 
from subsidization are charged a fee collected by CBP each time they 
import products into the United States. This helps negate the value of 
the dumping/subsidization and creates a fairer competition for U.S. 
companies. In findings of dumping, DoC issues a ``Final Determination'' 
that requires importing entities to pay AD/CVD before the case is 
considered resolved. EPA has placed a memo in the docket summarizing 
actions taken to date, as well as the HFC-relevant Final Determinations 
that it is aware of.
---------------------------------------------------------------------------

    \73\ ``U.S. Antidumping and Countervailing Duties.'' Trade.gov, 
International Trade Administration, www.trade.gov/us-antidumping-and-countervailing-duties.
---------------------------------------------------------------------------

    EPA is proposing that any entity that is subject to a DoC Final 
Determination and is requesting allowances for 2022 or 2023 must 
provide documentation of payment of the AD/CVD for HFC imported in 2017 
through the date of this proposed rule, or provide evidence that those 
imports were not required to pay AD/CVD for those years. EPA is 
proposing not to allocate to companies in 2022 or 2023 that CBP 
determines are not in compliance with or are otherwise in arrears with 
their AD/CVD during those years. After an entity is issued allowances, 
if it is subject to a DoC Final Determination and does not pay the 
required AD/CVD within the required time frame, as determined by CBP, 
EPA proposes that the company may have its allowances for that year 
revoked or retired, or may not be issued future allowances or may 
receive a reduced allocation. EPA proposes that it could, after 
consulting with CBP, also ban a company from receiving allowances in 
the future as a result of noncompliance with the regulations governing 
payment of AD/CVD.
    EPA is also proposing that the Agency would have the discretion to 
revoke, retire, or withhold allowances for companies that fail to use 
the correct Harmonized Tariff Schedule (HTS) codes with each shipment 
of HFCs or HFC blends. Intentionally misdeclaring the HFC or HFC blend 
in a shipment is one way importers may attempt to illegally import HFCs 
without allowances or with fewer allowances. As noted earlier, EPA 
intends to work with CBP to institute an automated electronic mechanism 
to check in real-time if an importer has sufficient allowances for a 
particular shipment. Errors on customs forms would inhibit EPA's 
ability to conduct this crosscheck to ensure accuracy in and compliance 
with EPA's allowance system. EPA is also proposing that the Agency 
would have the discretion to ban a company or the company owner(s) from 
receiving future allowances if the company repeatedly misreports HTS 
codes.

C. What process is EPA proposing to apply administrative consequences 
for allowances?

    EPA has provided examples where retirement, revocation, or future 
withholding of allowances may be warranted, including: falsifying or 
not disclosing relevant information in the case of application-specific 
allowances or new entrants; producing or importing, or attempting to 
produce or import, HFCs in excess of AIM Act allowances or otherwise 
not in compliance with AIM Act regulations (e.g., using HFCs claimed to 
be for feedstocks or in transhipments for other purposes); and an 
entity in arrears for any AD/CVD. These situations are not meant to be 
exhaustive, but instead are intended as examples of when EPA might 
exercise discretion to apply one or more administrative consequences 
for allowances. Additionally, any practice or combination of practices 
specified in the proposed regulatory text in Sec.  84.5 ``Prohibitions 
for regulated substances'' may warrant EPA exercising discretion to 
apply one or more administrative consequences for allowances. EPA seeks 
comment on whether there are additional non-compliant activities it 
should explicitly list as instances where the Agency could retire, 
revoke, or withhold allowances. EPA has also described what a ban on a 
company and its owner(s) would entail with respect to allowances. As 
stated earlier, these administrative consequences are not meant to 
replace or supplant any applicable enforcement action that may be taken 
under any available statutory authority; rather, such consequences 
would be in addition to any applicable enforcement action.
    EPA is proposing the following general process for retiring, 
revoking, or withholding allowances, and for banning a company or its 
owner(s) from receiving or obtaining allowances:
     Upon evidence or suspicion of practices including but not 
limited to the examples provided earlier, EPA would provide notice of 
impending allowance retirement, revocation, or withholding, or notice 
of impending ban, to the company that would set forth the facts or 
conduct that provide the basis for action. Notice would be provided no 
less than 30 days before the impending action. During this 30-day 
period, EPA proposes that the company would not be allowed to expend or 
transfer its allowances.

[[Page 27187]]

     Any company that receives such a notice of impending 
allowance retirement, revocation, or withholding, or notice of 
impending ban may choose to provide any information or data to support 
why their allowances should not be retired, revoked, or withheld, or 
why they should not be subject to a ban from receiving or obtaining 
allowances, within 14 days of the date of the Agency's notice. If EPA 
does not receive a response within 14 days, the impending action would 
be effective on the date specified in the notice, but not sooner than 
the expiration of the 14-day window.
    After review of the supporting data or information provided by the 
company receiving notice, EPA could decide to revoke or modify its 
notification, continue with the retirement, revocation, or withholding 
of allowances, or continue with the implementation of a ban from 
receiving or obtaining allowances. EPA's decision would occur within 30 
days of the date of the Agency's notice. Should EPA revoke its 
notification, the company's allowances would be unfrozen; and, should 
EPA continue with its impending action, the company's allowances would 
remain frozen until the effective date of the retirement, revocation, 
withholding, or permanent ban.

D. What is EPA proposing for packaging and labeling requirements?

    This section discusses EPA's proposals to require: (1) A ban on 
disposable cylinders, such as DOT-39 cylinders, with limited 
exceptions, (2) the accurate labeling of the contents of cylinders, and 
(3) the use of tracking or identification technology. Together these 
requirements would disincentivize illegal imports, facilitate discovery 
of illegal imports, provide for better tracking of HFCs, and ensure 
that companies that have successfully maintained good standing are not 
put at a competitive disadvantage.
1. Ban on Disposable Cylinders
    EPA is proposing a ban on the import and placement of HFCs in 
disposable cylinders with limited exceptions. The vast majority of HFCs 
packaged for sale to contractors are currently in DOT-39 disposable 
cylinders. A DOT-39 cylinder is strictly non-refillable and thus is 
designed for single use unlike refillable cylinders. A number of 
countries, including the EU member states, Australia, India, and 
Canada, have banned disposable cylinders in their countries.
    Losses from all cylinders can occur under a variety of 
circumstances during transport, storage, and disposal, the frequency 
and severity of which depends in part on the type of cylinder. However, 
HFC losses are most likely to occur and in the most significant 
quantities from disposable cylinders, including the residual amount of 
HFCs (heels) that remain in the cylinders. With disposable cylinders, 
these heels, which can measure up to eight percent of the quantity that 
was originally stored in the container, unless recovered would be 
released to the atmosphere when the cylinder is disposed of, with 
associated adverse consequences on the environment.
    EPA is proposing to prohibit the import and placement of HFCs in 
disposable cylinders beginning July 1, 2023. Prohibiting the use of 
disposable cylinders, such as DOT-39 non-refillable cylinders, would 
increase environmental benefit including by ensuring the heels left in 
a cylinder are not released to the atmosphere when disposable cylinders 
are discarded. At least on two occasions, Congress has requested that 
EPA study the use of refillable cylinders. EPA reviewed previous 
studies and has provided updated analysis in a technical support 
document that can be found in the docket for this rulemaking. EPA 
estimates that replacing disposable cylinders with refillable cylinders 
in the United States would prevent the release of up to 5.2 
MMTCO2e of HFCs per year.
    In addition to the potential environmental benefit, adding a 
prohibition on the import and placement of HFCs in disposable cylinders 
would help ensure compliance with the consumption allowance system. EPA 
understands that other countries, such as the EU member states, have 
found advantages to prohibiting disposable cylinders including a 
recognition that often HFCs entering their markets illegally are 
contained in disposable cylinders. Several studies have found that 
illegal HFCs are entering European markets in disposable cylinders.\74\ 
Prohibiting the use of disposable cylinders in the United States would 
provide CBP officers the ability to conduct a quick visual inspection 
to identify potentially illegal imports for follow-up.

Apr. 2019, https://reports.eia-international.org/doorswideopen.
---------------------------------------------------------------------------

    EPA recognizes that the vast majority of HFCs packaged in 25-pound 
cylinders currently use DOT-39 disposable cylinders. Therefore, EPA is 
proposing to prohibit the import and placement of HFCs in disposable 
cylinders beginning July 1, 2023. Since similar prohibitions have been 
successfully implemented in many other countries, EPA does not consider 
a longer lead time necessary but does recognize that a prohibition 
consistent with the effective date of the final rule may be too short 
to allow for an orderly transition.
    In developing this proposal, EPA considered one to two years from 
the publication of the final rule to transition to refillable 
cylinders. EPA is proposing that a compliance date of July 1, 2023, 
would provide appropriate time but is requesting comment on a shorter 
timeframe. EPA is not proposing a compliance date after January 1, 
2024, since EPA wants to ensure that HFCs in heels are not vented or 
otherwise go unused in order to meet demand when the next stepwise 
reduction in production and consumption occurs. Therefore, EPA is 
proposing to prohibit the import and placement of HFCs in DOT-39 and 
other disposable cylinders starting July 1, 2023, in advance of the 
step down in production and consumption that occurs on January 1, 2024. 
This timing also supports the proposal to establish a certification 
system for tracking legally imported and produced HFCs. EPA is also 
proposing to require that all refillable cylinders have a unique etched 
serial number. As noted later in the proposal, this etched number would 
be useful under the proposed certification identification and labeling 
requirements.
    Following the July 1, 2023, ban on disposable cylinders, EPA is 
proposing to still allow certain disposable containers, such as small 
cans of refrigerant with a self-sealing valve, that meet the 
requirements in 40 CFR 82.154(c)(2). These containers have a mechanism 
in place to reduce emissions, so there would not be the same 
environmental benefit from their ban as EPA perceives in banning all 
other disposable cylinders. For a more complete discussion of the ways 
self-sealing valves reduce emissions of refrigerant, see 81 FR 82272 
(November 18, 2016).
    EPA is considering how best to address disposable cylinders that 
are in existing inventory on July 1, 2023, and invites comment on this 
issue. This compliance date may provide sufficient time and notice to 
this industry to transition into refillable cylinders such that no 
special accommodation is needed. However, EPA could establish a limited 
sell-through provision, such as for six months, on the condition that

[[Page 27188]]

anyone wishing to sell HFCs in a disposable cylinder after January 1, 
2024, from their existing inventory would have to register each 
cylinder with EPA no later than November 15, 2023, and provide 
information on the HFC or HFC blend in each cylinder and the origin of 
the cylinders (e.g., imported, purchased from supplier X on Y date) to 
distinguish them from new refrigerant cylinders entering the market. To 
support effective enforcement and compliance of the ban, EPA is 
proposing that as of January 1, 2025, 18 months after the disposable 
cylinders ban takes effect, EPA would prohibit the sale or offer for 
sale of regulated substances contained in disposable cylinders. 
Eighteen months should be sufficient to allow for existing inventory of 
regulated substances contained in disposable cylinders to be sold or 
transferred to refillable cylinders. EPA requests comment on whether 18 
months is an appropriate length of time for cylinders to work their way 
through the market, or if more or less time is warranted.
2. Ban on Importing HFCs To Be Used in Feedstocks in Cylinders
    EPA is proposing to prohibit the import of HFCs intended for use in 
a process resulting in their transformation or destruction in cylinders 
designed to hold 100 pounds or less of a regulated substance. As 
discussed in section VIII.F. of this preamble, EPA is proposing that 
such HFCs may be imported without a consumption allowance. These HFCs 
are typically imported, and used, in large volumes at specific 
facilities. EPA does not anticipate this proposal would affect current 
business practice. Instead, this proposal is intended to deter attempts 
to claim that imports of HFCs in cylinders do not require allowances 
because they are for transformation or destruction processes. EPA 
requests comment on the typical container size for HFCs sold for use in 
a process resulting in their transformation or destruction, and whether 
100 pounds is an appropriate threshold for this requirement. The Agency 
expects it could be higher than 100 pounds, but takes comment on 
whether to finalize a higher or lower threshold.
3. Labeling
    EPA is proposing that all containers that contain a regulated 
substance in bulk (e.g., ISO tanks, drums, cylinders of any size, or 
small cans) must have an affixed label or other marking that indicates 
the specific HFC(s) in that container. Specifically, EPA is proposing 
that all containers of bulk regulated substances should state, legibly 
and indelibly, in numbers and letters at least \1/8\ inch high, the 
common name of the HFC or HFC blend contained, and the composition and 
ratios of the HFCs if a blend. This font size is consistent with the 
DOT-39 labeling standards (see 49 CFR 178.65). EPA seeks comment on 
whether the label should also include the quantity of HFC in the 
container. EPA does not anticipate that this proposal would result in 
any additional burden on refrigerant distributors or importers as such 
identification is the current practice. EPA requests comment on this 
presumption and whether there would be any burden associated with this 
proposal.
    This proposal is intended to facilitate more effective enforcement 
and deter future noncompliance. EPA anticipates that smugglers will 
misidentify HFCs as some other compressed gas to evade import 
restrictions. One method used to illegally import ODS refrigerants was 
to identify it as an HFC, since allowances were not required to import 
HFCs at that time. Under this method of illegal import, once the 
unidentified or misidentified regulated substance entered the United 
States a domestic counterpart who knew the true identity of the 
compressed gas would relabel the cylinder with the correct substance so 
that it could be commercially useful. As such, EPA is also proposing 
that repackaging material that was initially unlabeled or mislabeled 
would be considered a knowing violation of this subpart.
    EPA is also aware that some virgin material may not contain 
components in ratios that match that required of the blend. While 
historically that may have been due to the refrigerant being of low 
quality, there are now incentives for importers to intentionally 
misstate the contents which has implications for the allocation system. 
Mislabeling a blend that has a high EVe as a blend with a lower EVe or 
labeling a cylinder with a random mixture of HFCs as a particular blend 
both are misrepresentations that would cost allowances that do not 
reflect the actual contents of the cylinder. Such violations would 
hinder the Agency in meeting the requirement under subsection (e)(2)(B) 
of the AIM Act that EPA is charged with ``ensur[ing] that the annual 
quantity of all regulated substances produced or consumed in the United 
States does not exceed'' the statutorily prescribed phasedown schedule. 
This proposal is aimed at helping ensure EPA meets the directive of 
subsection (e)(2)(B).
    To provide a way to check the accuracy of the label, EPA is 
proposing to require producers and importers to batch test their 
product and retain records indicating the results of the batch testing. 
EPA invites comment on how to best implement this proposal.
    EPA also requests comment on whether to require that containers 
purporting to contain a specific HFC or an ASHRAE designated blend with 
an HFC component meet the specifications in Appendix A to subpart F of 
part 82--Specifications for Refrigerants. Currently, under the CAA 
section 608 regulations, reclaimed refrigerant is required to meet 
specifications based in large part on the AHRI-700 standard for purity 
before it can be released into the market. Based on input from 
industry, EPA is now aware that virgin material potentially could 
include impurities or that the ratio of components in a blend do not 
match that required of the blend.\75\

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

    If the bill of lading or other evidence suggests that cylinders 
contain HFCs but the cylinder itself is not labeled or the labeling is 
illegible, EPA is proposing to presume that the container is completely 
full of HFC-23, unless the importer verifies the contents with 
independent laboratory testing results and fixes the label on the 
container before the container enters interstate commerce. Under this 
proposal, a company would have to expend the requisite allowances to 
import HFC-23 in order to be able to legally bring the unlabeled HFCs 
into interstate commerce (i.e., clear Customs). The company could also 
choose to have the shipment held at port until they can arrange for 
testing to show what the contents are and would need to relabel the 
container before clearing Customs and enter interstate commerce. The 
goal of this presumption is to deter illegal activity and promote 
accurate and clear labeling, while also simplifying the process for 
EPA, in coordination with CBP for imports, to deduct a sufficient 
number of allowances at the point of import. HFC identifiers and a 
certified laboratory to verify the contents of a container may not be 
available, for example at a port, so providing a clear presumption that 
could be used in such circumstances would facilitate compliance and 
enforcement efforts. This proposal would reduce the safety risk of 
having unlabeled cylinders at Customs or in commerce. It would also 
reduce the potential to damage

[[Page 27189]]

equipment resulting in the release of refrigerant and harm to the 
environment. EPA requests comment on appropriate measures to deter the 
import of unlabeled cylinders. EPA also requests comment on whether the 
agency should instead simply deny entry or ban import of such unlabeled 
cylinders.

E. What is EPA proposing to require for auditing?

    EPA is proposing to require external audits performed by certified 
public accountants (CPAs) on an annual basis for all producers, 
importers and reclaimers to improve the integrity of the allocation 
program. An audit would be a systematic review of financial records and 
other transaction documents to verify that the annual reports provided 
to EPA are accurate. EPA is proposing to require external audits 
conducted by an independent accountant or auditor in the United States 
that is certified by the American Institute of Certified Public 
Accountants. EPA is soliciting comments on additional ways to ensure 
the independence of auditors and integrity of the auditing process, 
including potential compliance-related efforts.
    Numerous economic studies have found that third-party auditing 
improves company and individual compliance with the 
law.76 77 78 EPA has used third-party auditing to improve 
regulatory compliance in rules, including the Renewable Fuels Standard 
(79 FR 42080). As noted in the Renewable Fuels Standard rulemaking, 
there is expert consensus that well-implemented third-party auditing is 
a good use of limited enforcement and oversight resources. Independent 
and objective audits are a valuable tool to improve compliance and 
accuracy among all companies, not just those with covert malicious 
intent to be inaccurate or unfair in their auditing or reporting.

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

    EPA is proposing that entities subject to the reporting requirement 
have auditors review the reports they provide to the Agency, and the 
inputs for developing those reports, to ensure that they were complete 
and accurate. At a minimum, reporters would have auditors review, as 
appropriate:
     The amount of production and consumption allowances 
allocated;
     The amount, timing, and parties to allowance transfers, 
and the associated documentation and offset amount;
     The amount of HFCs imported, exported, produced, 
destroyed, transformed, or reclaimed;
     For allocation-specific allowances, the amounts of 
allowances conferred, HFCs purchased, the specific application for 
which the HFCs were provided, and the names, telephone numbers, and 
email addresses for contact persons for the recipient companies;
     The date and the port from which HFCs were imported or 
exported;
     A copy of the bill of lading and the invoice indicating 
the quantity of HFCs imported or exported;
     Relevant commodity codes;
     The number and type of railcars, ISO tanks, individual 
cylinders or drums, small cans, or other containers used to store and 
transport HFCs;
     List of QR codes used and the digital transaction history 
associated with those codes; and
     Other information deemed relevant.
     EPA is proposing that the third-party auditor would send 
the results of their audit directly to EPA no later than May 31 of the 
subsequent year. EPA is proposing May 31st because it should allow 
sufficient time after the annual reports are due to conduct an audit.
    EPA solicits comments on requiring an annual audit performed by a 
CPA covering the elements listed in this section. Among other topics, 
the Agency is interested in comments on the frequency of the audits, 
the qualifications of the auditors, and the timing for submission of 
the audits to EPA. Recognizing there is a cost for an audit regardless 
of the size and there may be less environmental value in requiring an 
audit for a company reporting small volumes of HFCs, EPA also seeks 
comment on whether it should limit the frequency of audits for 
companies that report less than 25,000 MTEVe. EPA also seeks comment on 
whether the auditor should review additional records, such as records 
of raw materials and feedstock chemicals used at each facility for the 
production of regulated substances, or whether that type of review 
would be more appropriate for an engineer.

F. Petitions To Import HFCs as a Feedstock or for Destruction

    EPA is proposing that all bulk imports of HFCs into the United 
States either require the expenditure of consumption allowances or be 
authorized through a non-objection notice issued by EPA. This section 
discusses EPA's proposal to establish a petition process to authorize 
entities to import HFCs without expending allowances. There are two 
types of shipments addressed in this subsection. First, virgin HFCs are 
imported for use in a process resulting in their transformation (i.e., 
as feedstocks) or destruction. Second, used HFCs are imported into the 
United States to be disposed of at a destruction facility using an 
approved destruction technology.
    The definition of ``produce'' in section (b) of the AIM Act 
excludes the manufacture of a regulated substance that is used and 
entirely consumed (except for trace quantities) in the manufacture of 
another chemical. The process is known as transformation and the 
regulated substances used and consumed are called feedstocks. HFCs used 
for transformation are exempt from production, and therefore 
consumption, and do not require allowances. Typically, companies that 
need HFCs for feedstock use create the HFCs at the same facility, but 
HFCs can also be transported from another location. This is called 
second-party transformation. This proposal addresses the risk of 
unlawful behavior associated with transporting feedstock HFCs.
    With respect to destruction of HFCs that have been used and 
recovered, these chemicals can become contaminated beyond the point 
that reclamation is economical. Providing a pathway for proper disposal 
of these used HFCs within the United States can benefit the environment 
and the domestic destruction industry. EPA is proposing to limit the 
petition process for destruction to used HFCs, and require consumption 
allowances to be expended to import virgin HFCs, to keep this process 
narrow and tailored in an effort to reduce the potential for illegal 
imports.
    EPA is proposing a petition process based in large part on the one 
found in 40 CFR 82.13(g)(5) and 82.24(c)(6) for the import of used ODS 
for destruction. EPA proposes to require the importer of HFCs for 
feedstocks or destruction to submit a petition to EPA at least 30 
working days before the shipment's departure from the foreign port. EPA 
is proposing other elements to verify that these imports will in fact 
be transformed or destroyed.

[[Page 27190]]

    Specifically, EPA proposes that the petition would include the 
following elements: (i) Name, commodity code, and quantity in kilograms 
of each regulated substance to be imported; (ii) name and address of 
the importer, the importer ID number, and the contact person's name, 
email address, and phone number; (iii) name and address of the 
consignee and the contact person's name, email address, and phone 
number; (iv) source country; (v) 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 
the U.S. port of entry, the expected date of shipment and the vessel 
transporting the material, 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; 
(vi) name and address of any intermediary who will hold the material 
before the HFCs are transformed or destroyed; and (vi) name, address, 
contact person, email address, and phone number of the responsible 
party at the transformation or destruction facility; and (vii) 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.
    Within 30 working days of receiving a complete petition, EPA would 
send either a non-objection notice or an objection notice to the 
petitioner. The Agency may object to the petition if the petition 
provides insufficient information or if it contains or is suspected to 
contain false or misleading information. A petitioner may re-petition 
once if the Agency indicated ``insufficient information'' as the basis 
for the objection notice.
    EPA is proposing that HFCs imported under this process for 
transformation or destruction be transformed or destroyed, as 
applicable, within 60 days of being imported into the United States. 
EPA is taking comment on whether it should consider a longer timeframe 
such as 90 days. EPA is also taking comment on whether it is 
appropriate to allow a longer timeframe for regulated substances to be 
used as feedstocks, up to 12 months. EPA is also proposing to require 
that the petitioner submit records indicating that the substance has 
been transformed or destroyed within 45 days after its transformation 
or destruction. EPA is also proposing supporting prohibitions in Sec.  
84.5 for provisions that will be similar to 40 CFR 82.4(j)(2) and 
82.15(b)(3) to prohibit the import of HFCs for processes that result in 
their transformation or destruction, or disposal by destruction, 
without having received a non-objection notice consistent with this 
petition process.
    By providing an importer with documentation that the import is 
authorized, this proposal would both expedite Customs clearance and 
result in a more secure border. It would prevent an importer from 
falsely claiming that their shipment does not require allowances or 
authorization from EPA because it is exempted. It also would track the 
movement of the import after entering the United States by attaching 
reporting obligations of the transformer or destruction facility.
    EPA requests comment on other approaches to prevent the import of 
HFCs mislabeled as feedstock or intended for disposal by destruction. 
For example, EPA is considering whether a notification to EPA, rather 
than a petition, could be sufficient in preventing unlawful trade. 
Alternatively, EPA could require importers to register with the agency 
to be able to import HFCs for transformation and destruction uses or 
disposal and/or participate in the QR code tracking system.

G. How is EPA proposing to track the movement of HFCs in commerce?

    The Agency is proposing to establish a certification program that 
would use tracking or identification technology such as QR codes \79\ 
or some other tracking identifier to track the sale and distribution of 
HFCs starting January 1, 2024. This proposal seeks to ensure that HFCs 
introduced into and distributed or sold in the United States are 
covered by an allowance or were reclaimed. Distribution and sale of 
HFCs that did not enter the market legally would lack a certification 
and thus could be easily identified. This program would support 
compliance and, where needed, enforcement action. Buyers would also be 
able to know that they are purchasing legal HFCs. EPA is taking comment 
on the proposals related to this electronic tracking system including 
ways to make it simple and not burdensome to use, while maintaining the 
same functionality including the ability to report electronically.
---------------------------------------------------------------------------

    \79\ A QR code is a type of matrix barcode that contains data 
for a locator, identifier, or tracker that points to a website or 
application using standardized encoding modes to store data. It is 
recognizable as black squares arranged in a square grid on a white 
background, which can be read by an imaging device such as a camera. 
In this proposed rule we use the phrase QR code as a stand-in for 
'physical media that facilitate digital inventory tracking'. The 
final rule may or may not require QR codes specifically (bar codes 
and RFID chips are other possibilities, for example).
---------------------------------------------------------------------------

    Under this proposal, EPA would assign certification IDs to 
producers and importers based on the quantity of production and 
consumption allowances they have. As allowances are expended, the 
certification IDs associated with those allowances would be assigned to 
the corresponding HFCs, prior to the shipment of HFCs clearing Customs 
or being readied for transport from a production facility. For imports, 
the appropriate QR code would need to be affixed prior to clearing 
Customs so the certificates could be confirmed by Customs while still 
at the port. The certification system would be linked to the allowance 
allocation to ensure that allowances were obtained for each MTEVe 
produced or imported. The certification would be tracked using a 
physical label containing a QR code affixed to the container in which 
the material was sold after being produced in the United States or 
imported. When the QR code is scanned it would point to a website with 
a database that would indicate at least the initial allowance holder, 
the quantity and common name of the HFC, the name it is currently being 
marketed under, and the date of production or import.
    Each time the material is bought/sold, or partitioned into another 
container, the tracking information would be updated. If HFCs are 
blended, the database entry for the identifier for that container would 
be updated by the blender to reflect that new information. EPA would 
establish protocols that ensure once the tracking information is 
entered, the system would not allow the data to be altered 
retroactively, thereby preserving the integrity of the information. EPA 
is proposing that the certification continue to be tracked until it is 
sold to the final customer. The final customer will differ depending on 
the use of the HFCs. For example, EPA would consider an aerosol filler 
to be the final customer given the HFCs are being incorporated into a 
product. Similarly, a factory charging HFC refrigerant into an 
appliance would be the final customer. HFCs used in field charged or 
field serviced applications would continue to have the certification 
accompany them until they are sold to a contractor or technician.
    EPA's general understanding of the supply chain is that HFCs (from 
production or import) are shipped in large ISO tanks, individual 
cylinders or drums, and small cans. The material is then sold to 
entities that would be considered part of the distribution chain--that 
is, the entity is neither the importer nor the end user (such as a

[[Page 27191]]

refrigeration or air conditioning contractor). The material may change 
hands one or more times before it is purchased by the final entity in 
the distribution chain and subsequently sold to the final customer. EPA 
is proposing that anyone selling HFCs would need to be registered in 
the system to allow for legal HFC to be tracked from the point of 
introduction into commerce to the point of sale to the final customer 
(i.e., the person that will use the HFC) so that any illegal HFC 
offered for sale at any point in the distribution chain could be 
identified. Sellers would need to scan the containers as they are sold, 
and buyers who intend to sell the HFCs, other than the final customer, 
would need to do the same. EPA seeks comment on ways it could minimize 
burden for users, such as allowing for whole purchases or pallets to be 
scanned under one code, or having the system capture the information in 
a way where no or limited data entry is required once logged into the 
system.
    Anyone who is filling a container or cylinder, whether for the 
first time or when transferring HFC from one container to one or more 
smaller or larger containers, would be required to enter information in 
the system and generate a new QR code for the new containers and add 
information on: the brand it would be sold under, the quantity and 
composition of HFC(s) in the container, the date it was packaged or 
repackaged, the certification IDs associated with the HFCs (if being 
repackaged), the quantity of containers it was packaged in, and the 
size of the containers. EPA is providing additional information in the 
docket concerning the supply chain for HFCs and the entities we believe 
are potentially affected by this system, and seeks comment on whether 
there are other entities that are not reflected in the memo. EPA also 
seeks comment on whether exporters should have to register and note 
when they export HFCs, such as destination, date of export, the 
certification IDs associated with the containers exported, and other 
Customs records (including bills of lading), to support the proposed 
reimbursement of allowances when HFCs produced or imported with 
allowances are exported.
    EPA recognizes that not all HFCs would enter the market through the 
expenditure of an allowance. Most significantly, HFCs recovered in the 
field (e.g., refrigerants) are sent for reclamation and can be resold 
into the market after they meet specific purity standards. Under the 
CAA section 608 regulations, reclaimers must be certified by EPA and 
report the amounts and names of the HFCs reclaimed on an annual basis. 
EPA would generate certification IDs for the reclaimer in an amount 
equal to the quantity reclaimed in the previous year plus an amount 
based on the average annual growth in total U.S. HFC reclamation in the 
prior three years or five percent, whichever is higher. EPA anticipates 
reclamation will increase over time. Reclaimers could request 
additional certification IDs from EPA if the initial distribution was 
insufficient and the reclaimer provides information to the Agency that 
can allow the Agency to confirm that additional reclamation is 
occuring. The data behind that QR code would be similar to that for 
HFCs produced or imported with allowances but would indicate that it is 
reclaimed and list the reclaimer.
    To ensure regulated HFCs sold by reclaimers are legally reclaimed 
material and eligible for sale, EPA is proposing that reclaimers would 
need to log into the certification ID tracking system and, for each 
container of HFCs prior to selling regulated substances, provide 
information like the date the HFC was reclaimed and by whom; what 
regulated substance(s) (and/or the blend containing regulated 
substances) is in the container; how many kilograms were put in the 
container and on what date the container was filled; whether the purity 
of the batch was confirmed to meet the specifications in appendix A to 
40 CFR part 82, subpart F; on what date the batch was tested; and who 
certified it met the specifications. If a container is filled with 
reclaimed and virgin HFC(s), EPA proposes that the reclaimer would have 
to also provide information on how much virgin HFC was used and what 
the origin of that material was (e.g., the certificate IDs associated 
with that material). EPA expects there could be a way to build in a 
batch feature so the reclaimer could enter a total mass of HFCs that 
are reclaimed and a total mass of HFCs that are virgin and the 
certification IDs associated with the QR code on each of the containers 
would reflect the relative percentage of reclaimed and virgin material 
associated with each container, assuming the virgin and reclaimed HFCs 
were evenly mixed before being put into the new containers.
    EPA is also aware that under CAA sections 608 and 609, recovered 
HFC refrigerant can be resold if it was used only in a motor vehicle 
air conditioner (MVAC) or MVAC-like appliance and is to be used only in 
an MVAC or MVAC-like appliance and recycled in accordance with 40 CFR 
part 82, subpart B (see 40 CFR 82.154(d)). EPA is proposing to allow 
this practice to continue without requiring registration in the 
certification identification system. EPA requests comment on whether 
additional recordkeeping and/or reporting should be required, such as 
the total quantity of HFCs purchased, recovered, recycled on-site, sent 
off-site for reclamation or destruction, and charged into MVACs. If 
someone is selling bulk HFC, other than for use by that company for 
servicing MVACs, for example to another auto shop, they would need to 
be registered in the certification ID tracking system.
    EPA recognizes that a large quantity of HFCs will already be in the 
United States market prior to the finalization of this rule. Therefore, 
the Agency is proposing a compliance date of January 1, 2024, for these 
provisions. That would allow time for much of the HFCs in the 
distribution chain prior to that date to work its way through the 
supply chain. EPA is proposing that as of January 1, 2024, it would be 
unlawful to sell or distribute HFCs in a container that does not bear a 
legible QR code. The sale and purchase of uncertified HFC (or HFC in a 
container without a legible QR code) would be illegal and subject to 
civil and criminal enforcement to prevent smuggling and/or bypassing of 
the exchange system.
    EPA proposes that anyone wishing to sell HFCs produced, imported, 
or reclaimed prior to January 1, 2024, must register each container of 
HFC with EPA no later than November 15, 2023, for EPA to assign a 
certification ID for each container. The registration must provide 
information on the amount(s) and type(s) of HFCs and HFC blends, the 
containers the HFC material is in, any unique identification numbers 
assigned to the containers, and the origin of the HFC(s) (e.g., 
imported, purchased from supplier ``X'' on Y date) to verify they were 
legally imported. EPA would assign the appropriate certification ID for 
each container of HFCs if sufficient documentation is provided. EPA is 
concerned that smugglers could attempt to register illegally imported 
material through the process and seeks comment on whether additional 
requirements are needed to ensure illegal HFCs are not receiving 
certification IDs that would in effect make them legal. EPA is 
proposing to require a one-time report for anyone who requests 
certification IDs for previously imported, produced, or reclaimed HFCs 
including the company's inventory levels as of December 31 for the 
prior three to five years, so EPA could assess whether there was 
significant upward growth during that time. EPA could also require a 
random audit of the company's

[[Page 27192]]

records to ensure the information provided to EPA is accurate. EPA 
could also establish administrative consequences for suppliers that are 
found to not be in compliance or who have misrepresented information to 
EPA.
    Most buyers desire to purchase only legal HFCs. However, in the 
absence of a way to distinguish between legal and illegal HFCs, buyers 
could unwittingly buy illegal HFCs and may be unintentionally 
supporting the demand for and trade in illegal HFCs. For example, in an 
enforcement case that concluded in 2018,\80\ there was evidence that 
cylinders likely imported without allowances were bought and sold by 
multiple suppliers before they were finally determined to be 
counterfeit and likely illegally imported. There was no evidence that 
anyone in the supply chain knew the material was likely illegally 
imported other than the importer until the final purchaser noticed the 
refrigerant was off-spec and in a cylinder that did not match the 
typical packaging for that brand of product. For this reason, it is 
important to involve both the buyer and seller in the accountability 
process and provide the buyer with accurate information on the origin 
of the HFCs they intend to purchase.

    EPA views the use of QR codes that would be generated by EPA for 
production, import, and reclamation of HFCs as an alternative to a more 
burdensome recordkeeping option described below in this paragraph. EPA 
seeks comment on whether such a recordkeeping and reporting provision, 
that would not be not backed up by an EPA electronic system, would be 
appropriate in lieu of a system based on electronic reporting. EPA 
seeks comment on whether such a recordkeeping and reporting provision, 
which would not be backed up by an EPA electronic system, would be 
appropriate in lieu of a system based on electronic reporting. This 
type of approach might still require a QR code, additional label, or 
other identifier be affixed on each container at the point of import, 
to allow for CBP to verify the contents of the container and/or to 
identify the importer, or once the produced or reclaimed material is 
first put into a container. But the movement of HFC material would not 
necessarily be reported in real-time by market actors by scanning those 
codes. Instead, detailed recordkeeping, and potentially reporting 
requirements, would be used to document every sale of HFCs to verify 
the chain of custody from the point of production, import, or 
reclamation to the end user or final seller of the HFC. EPA could also 
require a signed statement between the buyer and the seller verifying 
that the material being sold was acquired legally (e.g., imported or 
produced with allowances). As part of the paperwork, the seller would 
have to maintain records of the prior seller(s) back to the point of 
production, import or reclamation. EPA could also require this 
information be reported regularly to the Agency, similar to the 
requirements for Renewable Identification Numbers (RINs) under the 
Renewable Fuels Standard. If EPA were to require substantial 
recordkeeping and reporting it could create additional burden for all 
parties, and those at the end of the distribution chain, frequently 
small businesses, could be disproportionately impacted. As a result, 
EPA is proposing a more streamlined approach and would develop an IT 
system that could simplify this process and store the appropriate 
records and data needed to verify the chain of custody of HFCs.
    EPA is soliciting comment on establishing a certification program 
that would follow the HFC through the supply chain including instances 
where the HFCs are repackaged and/or blended as described above. EPA 
solicits comment on alternatives to the proposed QR code mechanism, 
including not relying on physical media attached to the shipment, and 
other means to access a database. EPA understands that many companies, 
including companies producing, importing, and reclaiming HFCs already 
use digital inventory systems. EPA welcomes feedback on how it could 
set up such a system. EPA also welcomes comments on how to streamline 
data entry by entities that subsequently purchase the material after 
the legal HFCs are assigned a tracking ID, including the use of QR 
codes, starting January 1, 2024. EPA is also requesting comment on the 
January 1, 2024, compliance date, which would align with the proposed 
2024 reduction in production and consumption and would follow closely 
behind the proposed prohibition on the use of disposable cylinders.
    If EPA were to finalize a certification ID tracking system with QR 
codes, EPA is proposing to release several data elements associated 
with each container of HFCs to potential buyers of HFC material, to 
support this system. To allow buyers of HFCs to determine whether the 
HFC they are purchasing is legal to buy, EPA proposes to release the 
following information: (1) Whether the HFC being sold is legal to 
purchase based on existing records; (2) when the HFC was produced, 
imported, or reclaimed and by whom; (3) what HFCs are included in the 
container; (4) if reclaimed HFC, whether the purity of the batch was 
confirmed to meet the refrigerant purity standard in appendix A to 40 
CFR part 82, subpart F (based on AHRI 700-2016), when was that 
confirmed, and by whom; (5) what the brand name associated with the 
container is; and (6) all prior sales of the certification ID 
associated with a container of HFCs.
    As noted previously, certification-specific data would accompany 
each kilogram of HFC moving through commerce (as tracked with a QR 
code). While EPA sees value in releasing all of these data to the 
general public in a comprehensive database both for transparency and to 
enable the certification ID tracking system to fully operate in support 
of overall program compliance, EPA anticipates that if all information 
was publicly available in the database, item (6) could potentially 
divulge information submitters customarily keep private or closely 
held. For example, if all the data in the database were available 
publicly without the need to scan every container of HFCs, someone 
could identify the total amount of each HFC produced or imported by a 
company in a given year and all the customers associated with a given 
producer or importer. EPA is seeking comment on whether submitters 
consider the information submitted for item (6) to be information they 
customarily keep private or closely held. If so, the Agency will make a 
decision in the final rule as to whether the Agency will provide an 
express assurance of confidentiality for the information and how it 
will protect that information from unauthorized disclosure.
    Alternatively, to protect information submitters may customarily 
consider to be private or closely held, and to assuage concerns about 
divulging information in item (6), EPA proposes to not to make the full 
dataset available publicly. The Agency could limit the ability to view 
the data for a single container (or full shipment of containers) to the 
current buyer and seller. EPA sees several ways this could work. The 
Agency could restrict access to the system, so only registered users 
could scan a QR code, and a user would only be able to view active 
codes that they had scanned into their ``inventory.'' EPA could also 
limit the ability of an individual to view data in the system to within 
a certain time

[[Page 27193]]

period after scanning the code. EPA seeks comment on other ways to 
prevent the release of information submitters customarily consider 
confidential from such a system. If the Agency cannot identify a way to 
protect item (6), it could withhold that data element from inclusion in 
the publicly available data associated with the certificate tracking 
system.

IX. What are the proposed recordkeeping and reporting requirements?

    Subsection (d)(1)(A) of the AIM Act specifies that on a periodic 
basis, but not less than annually, each company 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 company: 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.

A. What generally applicable recordkeeping and reporting provisions is 
EPA proposing?

    EPA is proposing recordkeeping and reporting requirements for any 
company that produces, imports, exports, transforms, uses as a process 
agent, reclaims, or destroys regulated substances as well as any 
company that receives an application-specific allowance. Given that the 
AIM Act controls all production and consumption of HFCs in the United 
States, and data on import, export, destruction, reclaim, feedstock, 
and process agent use are relevant to determining national production 
and consumption figures, all companies would be subject to the proposed 
recordkeeping and reporting requirements. In other words, under this 
proposal, there would be no minimum threshold for reporting. The AIM 
Act in subsection (d)(1)(A) provides EPA with clear authority to 
establish reporting requirements that apply to ``each person who, 
within the applicable reporting period, produces, imports, exports, 
destroys, transforms, uses as a process agent, or reclaims a regulated 
substance'' (emphasis added).
    Unless otherwise specified, such as for application-specific 
allowance holders, EPA is proposing to require quarterly reporting. 
Quarterly reporting helps to ensure that annual production and 
consumption limits are not exceeded. The proposed frequency is 
necessary for the Agency to review allowance transfer requests, of 
which remaining allowances is a major component of the Agency's 
decision. In EPA's experience, many companies have expressed their 
preference for and found it easier to compile reports for a given 
quarter than to compile an annual report.
    EPA is proposing that reports required by this section be submitted 
to the Administrator within 45 days of the end of the applicable 
reporting period, unless otherwise specified. Quantities would be 
stated in terms of kilograms for each regulated substance unless 
otherwise specified. The report would need to be signed and attested by 
a responsible officer (EPA is proposing to consider an appropriate 
responsibility officer to match the meaning of the CAA (42 U.S.C. 7401 
et seq.)) and copies of records and reports would need to be retained 
for five years.
    EPA is proposing that reports required by any regulations finalized 
in this rulemaking be submitted electronically using the EPA's Central 
Data Exchange (CDX) through e-GGRT. EPA is working to minimize 
duplicative reporting between the AIM Act and the GHGRP and having 
reporting done through e-GGRT will aid in the synchronization of these 
systems. EPA is also proposing that reports be at the facility-level, 
and not at the corporate-level, which will also add in synchronization 
between these two programs and better allow utilization of the e-GGRT 
system. Reporting at the facility-level will also provide finer detail 
to aid in EPA's review of compliance throughout the system.

B. What recordkeeping and reporting is EPA proposing that is applicable 
to specific types of entities?

    This section presents a general overview of the types of records 
and reports EPA is proposing. EPA encourages readers to review the 
proposed regulatory text for the full reporting requirements.
Producers
    EPA is proposing to require a one-time report from producers to 
allow the Agency to understand how production volumes are measured, the 
quantity of fugitive losses, the efficiency of the production process 
for the regulated substance, the production capacity of their 
facilities, and a description of any use of a regulated substance as a 
process agent. Such information will allow EPA to better understand the 
monitoring in place, the accuracy of reporting, and the likelihood of 
emissions associated with production.
    EPA is proposing to require quarterly reporting of data that 
includes the quantity of each regulated substance produced, the 
quantity of allowances expended, and quantities produced for 
transformation or destruction. EPA is proposing 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. EPA is taking comment on whether these reports need to be 
submitted quarterly or could be submitted less frequently.
    EPA is proposing that producers report any companies that conferred 
application-specific allowances to the producer and the quantity 
conferred. Producers would also report the quantities of regulated 
substances sold for those applications, specifying amounts produced 
using conferred application-specific allowances and amounts produced 
with production and consumption allowances. This additional reporting 
on production for allocation-specific allowances would allow the Agency 
to track the use of application-specific allowances to confirm their 
appropriate use and calculate the level of production allowances needed 
in future years for the statutorily listed applications to ensure that 
EPA is allocating an appropriate amount.
    EPA is proposing that companies that produce regulated substances 
maintain records similar to those for the ODS program. This includes, 
among other things: records of the quantity of each regulated substance 
produced at each facility; copies of invoices or receipts documenting 
sale of regulated substances for use in processes that result in their 
transformation or destruction, or use as a process agent; and records 
of raw materials and feedstock chemicals used at each facility for the 
production of regulated substances. In addition, EPA is proposing that 
producers keep records that distinguish between regulated substances 
produced with application-specific allowances and those produced with 
general pool production and consumption allowances for an application 
listed in (e)(4)(B)(iv) and the quantity sold for use in those 
applications. As outlined in the application-specific allowance 
section, EPA is proposing that end users that are allocated 
application-specific allowances certify that the regulated substances 
purchased through conferral of application-specific allowances were

[[Page 27194]]

purchased solely for use in the application listed on the allowance and 
will not be resold or used in any other manufacturing process. Similar 
to the essential use provisions for ODS, EPA is proposing that 
producers maintain copies of those certifications for all conferred 
application-specific allowances. EPA is also proposing that producers 
maintain dated records of the quantity of each regulated substance used 
at each facility as a process agent.
    EPA is proposing that if a producer fails to keep records on their 
production or to submit reports regarding their production, EPA may 
determine that the producer produced at full capacity during the period 
for which records were not kept or reports were not submitted for 
purposes of determining possible violations. Producers would 
additionally be subject to enforcement for failure to keep records or 
submit reports.
Importers
    EPA is proposing that companies that import regulated substances 
provide quarterly reports that include, among other things, the total 
quantity imported of each regulated substance for that quarter 
distinguishing between quantities of consumption allowances expended 
and quantities imported under the exemptions for processes resulting in 
transformation or destruction or used HFCs intended for destruction. 
Separating these categories is necessary to determine whether the HFCs 
imported count towards the consumption cap. EPA is also proposing that 
reports include the amount imported using conferred application-
specific allowances to confirm their appropriate use and calculate the 
level of allowances needed in future years to ensure that EPA is 
allocating an appropriate amount. EPA is proposing 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. EPA is taking comment on whether these reports need to 
be submitted quarterly or could be submitted less frequently.
    EPA is proposing that companies that import regulated substances 
maintain records that form the basis of the reports outlined in the 
prior paragraph. For each shipment EPA is proposing that importers keep 
records of the following: the date on which the regulated substances 
were imported, the port of entry, the country of export, the importer 
number, the bill of lading, the invoice for the import, and the U.S. 
Customs entry number. EPA is proposing that the information on the bill 
of lading include the specific HFC(s) in the shipment, the volume of 
each HFC, and the correct HTS code to properly identify the HFC or HFC 
blend (i.e., ``mixtures,'' in the terminology of the International 
Trade Commission). EPA notes that these codes are in the process of 
being updated so that most commonly traded HFCs will have their own 
code (or be grouped with minimally traded HFCs) and most major HFC 
blends will fall under separate codes. EPA is also proposing 
recordkeeping requirements for imports of used regulated substances for 
destruction under the process in Sec.  84.25 including a copy of the 
petition to import for destruction, EPA non-objection notice, and 
documentation necessary to show that the regulated substance was 
destroyed.
Importers of Used HFCs for Destruction
    EPA is proposing that entities that import used HFCs for 
destruction without expending consumption allowances in accordance with 
the procedures outlined in Sec.  84.25 maintain for five years: a copy 
of the petition to import for destruction; the non-objection notice; a 
copy of the export license or export license application including an 
English translation thereof; U.S. Customs entry documents for the 
import that must include the commodity codes; records of that date, 
amount, and names of the regulated substance sent for destruction per 
shipment; an invoice from the destruction facility verifying shipment 
was received; and records from the destruction facility indicating the 
substances were destroyed.
Aggregators of Used HFCs Imported for Destruction
    EPA is proposing that companies that aggregate used HFCs that were 
imported for destruction under the process in Sec.  84.25 maintain 
documentation necessary to show that the regulated substance was 
destroyed, such as chain of custody information.
Transhipments
    EPA is proposing reporting and recordkeeping requirements for any 
company that tranships a regulated substance through the United States. 
EPA is proposing to require that the company notify EPA 30 days prior 
to a transhipment arriving at a U.S. port. The arrival notification 
must include the following information: (i) Name, commodity code, and 
quantity in kilograms of each regulated substance to be transhipped; 
(ii) name and address of the importer, the importer ID number, and the 
contact person's name, email address, and phone number; and (iii) the 
U.S. port of entry, the expected date of entry, and the vessel 
transporting the material. If at the time of submitting the petition 
the importer does not know this information, the importer is required 
to notify the Administrator of this information prior to the entry of 
the individual shipment into the United States.
    Once the material has left the United States, EPA is proposing that 
the company provide a second notification indicating as such. The 
departure notification must include (i) name, commodity code, and 
quantity in kilograms of each regulated substance to be transhipped; 
and (ii) date and vessel transporting the material.
    EPA is also proposing that the company maintain records that 
indicate that the regulated substance shipment (i) originated in a 
foreign country; (ii) is destined for another foreign country; and 
(iii) did not enter interstate commerce within the United States. EPA 
requests comment on whether EPA should also require monthly reporting 
(or other reporting frequencies) on the status of the HFCs held at a 
bonded warehouse.
Exporters
    EPA is proposing that exporters provide a quarterly report that, 
among other things, includes the name, quantity, and commodity code of 
each regulated substance exported, the date on which, and the port from 
which, the regulated substances were exported from the United States, 
and the country to which the regulated substances were exported. EPA is 
proposing that any exporter of used regulated substances must indicate 
on the bill of lading or invoice that the regulated substance is used.
Second-Party Transformation or Destruction
    EPA is proposing that any company that transforms or destroys 
regulated substances produced or imported by another company without 
expending allowances report annually on the names and quantities of the 
regulated substances transformed or destroyed for that year, and who 
they acquired those HFCs from. Companies would maintain records 
documenting, among other things, amounts purchased, transformed or 
destroyed, transformation or destruction verifications, and the names, 
commercial use, and quantities of the resulting chemical(s) when the 
regulated substances are transformed.

[[Page 27195]]

    Transformation--EPA is proposing that any company that acquires 
regulated substances for purposes of transformation must provide the 
producer or importer with a transformation verification that the 
regulated substances are to be used in processes that result in their 
transformation. To ensure the accuracy of the verification, EPA is 
proposing that verifications only be valid for 60 days. However, EPA is 
taking comment on whether that should be extended to 12 months to 
provide more flexibility to companies transforming HFCs. EPA proposes 
that the transformation verification would include the following: (i) 
The identity, address, and contact information of the company intending 
to transform the regulated substances; (ii) the quantity of regulated 
substances intended for transformation; (iii) the identity of shipments 
by purchase order number(s), purchaser account number(s), location(s), 
or other means of identification; and, (iv) the period of time over 
which the company intends to transform the regulated substances.
    Destruction--EPA is proposing that any company that purchases or 
receives and subsequently destroys regulated substances that were 
originally produced or imported without expending allowances shall 
provide the producer or importer from whom it purchased or received the 
regulated substances with a verification that the regulated substances 
will be used in processes that result in their destruction. EPA is 
proposing that the destruction verification include the following: (i) 
Identity and address of the company intending to destroy regulated 
substances; (ii) the destruction efficiency at which such substances 
will be destroyed; and, (iii) period of time over which the company 
intends to destroy regulated substances.
    Transformation--In addition to the requirements outlined for 
entities undertaking second party transformation, EPA is proposing that 
any company that transforms a regulated substance provide EPA with a 
one-time report containing the following information: (i) A description 
of the transformation use; (ii) a description of all technologies and 
actions taken to minimize emissions of regulated substances; (iii) the 
name of the product manufactured in the process; (iv) a list of any 
coproducts, byproducts, or emissions from the production line of any 
regulated substance that are other regulated substances, ozone-
depleting substances listed in 40 CFR part 82, subpart A, or hazardous 
air pollutants initially identified in Section 112 of the Clean Air 
Act, and as revised through rulemaking and codified in 40 CFR 63; (v) 
the estimated annual fugitive emissions by chemical associated with the 
transformation process; (vi) the anticipated ratio of regulated 
substance used for transformation to the amount of end product 
manufactured; and (vii) a mass balance equation of the transformation 
reaction.
    Destruction--In addition to the requirements outlined for entities 
undertaking second party transformation, EPA is proposing that any 
company that destroys regulated substances, whether as part of a 
process or as a disposal method of used substances, provide EPA with a 
one-time report containing the following information: (i) The 
destruction unit's destruction efficiency; (ii) the methods used to 
record the volume destroyed; (iii) the methods used to determine 
destruction efficiency; and, (iv) the name of other relevant federal or 
state regulations that may apply to the destruction process. Any 
changes to the information in paragraphs (e)(4)(i), (ii), and (iii) of 
this section must be reflected in a revision to be submitted to EPA 
within 60 days of the change(s).
Companies That Transfer Allowances
    As discussed in section VI.D. of this preamble, EPA is proposing to 
allow the transfer of allowances between companies. EPA proposes that 
both the transferer and transferee maintain a copy of the transfer 
request and a copy of EPA's non-objection notice.
Holders of Application-Specific Allowances
    EPA is proposing recordkeeping and reporting provisions for holders 
of application-specific allowances that builds on EPA's experience with 
the requirements for ODS essential-use allowance holders.
    Certification--EPA is proposing that any company issued 
application-specific allowances, or that receives application-specific 
allowances through a transfer, must certify to producers and importers 
when purchasing HFCs produced or imported using those allowances that 
the regulated substances were purchased solely for the specified 
application in subsection (e)(4)(B)(iv) of the Act and will not be 
resold or used for other purposes. A copy of the certification must 
also be maintained by the company who uses the HFCs produced or 
imported with those allowances.
    Biannual Reporting--EPA is proposing that recipients of 
application-specific allowances report by July 31 and January 31 of 
each year. EPA is proposing biannual reporting so as to gather the data 
necessary to meet two objectives: To provide end-of-year accounting 
that must be coordinated with other annual reporting processes, and 
providing information early enough in the year for the Agency to 
determine by October 1 the quantity of application-specific allowances 
to allocate for the next year.
    Specifically, EPA is proposing that recipients of application-
specific allowances report the following information: (i) The quantity 
of each regulated substance that was used for their application during 
the previous six months; (ii) the quantity of regulated substances 
acquired through conferring allowances that were imported during the 
previous six months; (iii) the quantity of regulated substances 
acquired through conferring allowances that were produced domestically 
during the previous six months; (iv) the companies to which 
application-specific allowances were conferred; (v) the quantity of 
regulated substances purchased without expending application-specific 
allowances during the previous six months (i.e., from the open market); 
(vi) the quantity of inventory of each regulated substance held by the 
reporting company or held under contract by another company for use on 
the last day of the previous six-month period (i.e., December 31 and 
June 30); (vii) the quantity of each regulated substance contained in 
products exported by the company during the previous six months; and 
(viii) the quantity of each regulated substance that was destroyed or 
recycled during the previous six months.
    EPA is proposing that the report due by July 31 of each year also 
include a request for application-specific allowances for the next 
calendar year which would include: Total quantity (in kilograms) of all 
regulated substances acquired and used in the previous three years; 
information on suppliers; whether HFCs were acquired through domestic 
production or import; whether HFCs were acquired through conferring 
allowances or from the general market; quantities held in inventory; 
and a description of any plans to transition to regulated substances 
with a lower exchange value or alternatives to regulated substances.
    EPA is also proposing that entities allocated application-specific 
allowances maintain the following records: Records necessary to develop 
the biannual reports; a copy of certifications provided to producers 
and/or importers when conferring allowances; a copy of the annual

[[Page 27196]]

submission requesting application-specific allowances; invoice and 
order records related to the purchase of regulated substances; records 
related to the transfer of allocation-specific allowances to other 
entities; and records documenting the use of regulated substances.
Process Agents
    EPA is proposing that any company that uses a regulated substance 
as a process agent provide EPA with a one-time report containing the 
following information: A description of the process agent use which 
includes details of the percentages of process agent retained within 
the process, recovered after the process, and emitted or entrained in 
the final product. The proposed one-time report would also include a 
description of all technologies and actions taken to minimize emissions 
of regulated substances; the name of the product and byproducts 
manufactured in the process; and the anticipated ratio of process agent 
emissions to end product manufactured.
    EPA is also proposing that any company that uses a regulated 
substance as a process agent provide EPA with an annual report 
containing the following information: An email address and phone number 
for a primary contact person and for an alternate; the amount of 
regulated substance used as a process agent; the amount of product and 
the amount of byproducts manufactured (including amounts eventually 
destroyed or used as feedstock); the stack point source emissions; and 
a description of any HFC emission reduction actions planned or 
currently under investigation.
Reclaimers of HFCs
    EPA is proposing that reclaimers report to EPA on the same schedule 
as for producers and importers--45 days after the end of each quarter 
(e.g., February 14 for the period ending on December 31 of the prior 
year). The data elements would generally be the same as what they 
report under 40 CFR 82.164(d), with some modifications. EPA is 
proposing the reports contain information on the quantities of used, 
reclaimed, and virgin HFCs held in inventory onsite at the end of each 
quarter. EPA is also proposing that reclaimers submit a one-time report 
with similar information on inventory, as well as the name of the 
laboratory that conducts the batch testing and a signed statement from 
that laboratory confirming there is an ongoing business relationship 
with the reclaimer, providing the number of batches tested for each 
regulated substance or blend containing a regulated substance in the 
prior year, and providing the number of batches that did not meet the 
specifications in appendix A of 40 CFR part 82, subpart F in the prior 
year. Under this proposal, reclaimers would have to maintain those 
records for five years, instead of the three years required under 40 
CFR part 82, subpart F. EPA also seeks comment on whether there are 
other entities that reprocess HFCs and resell them back into the market 
and if the existing universe of HFC reclaimers would be sufficient to 
satisfy the (d)(1)(A)(ii) requirements for reclaimers.
    Under the existing regulations in subpart F codified at 40 CFR 
82.164 reclaimers must also maintain records of the analyses conducted 
to verify that reclaimed refrigerant meets the necessary specifications 
prescribed in appendix A to 40 CFR part 82, subpart F, based on AHRI 
Standard 700-2016, and maintain records on a transaction basis for 
three years of the names and addresses of persons sending them material 
for reclamation and the quantity of the material (the combined mass of 
refrigerant and contaminants) by refrigerant sent to them for 
reclamation. EPA seeks comment on whether any reclaimers are selling 
HFCs for use in any of the six applications listed in subsection 
(e)(4)(B)(iv) of the AIM Act. EPA could consider finalizing additional 
reporting requirements for such sales, similar to the requirements for 
producers on the quantities of HFCs sold to users of HFCs for one of 
the six applications listed in the AIM Act. EPA also seeks comment if 
there are additional elements the Agency should be collecting such as 
quantities sent for destruction, data on reclamation from 2011--2013, 
quantity of inventory awaiting reclamation, or destruction to meet the 
requirements under the AIM Act.
Inventory
    EPA is proposing that all producers, importers, exporters, and 
reclaimers of HFCs annually report the quantity of each HFC they hold 
in inventory as of December 31 of each year. For reclaimers, the report 
must include inventory of reclaimed and used HFCs awaiting reclamation 
or destruction. This information would be due 45 days after the end of 
the calendar year (February 14). EPA is proposing that the first annual 
inventory report be due by February 14, 2022, to provide data on 
inventory held at the end of 2021.
    EPA is proposing to collect this information to help inform the 
Agency in its evaluation of petitions and/or requests submitted under 
the AIM Act. For example, subsection (e)(4)(B)(v) requires EPA to 
``review the availability of substitutes, including any quantities of 
the regulated substance available from reclaiming or prior 
production,'' (emphasis added). Similar language is included in 
subsections (f) and (i) of the AIM Act. Annual reporting would 
facilitate the timely review of petitions and/or requests since this 
information would already be in the Agency's possession.
HFC-23 Emissions
    For entities that own or operate facilities that generate HFC-23 
beyond the exemption for insignificant quantities in the definition of 
production, EPA is proposing a one-time report containing the following 
information: (i) Information on the capacity to produce the intended 
chemical on the line where HFC-23 is also produced; (ii) description of 
actions taken at the facility to control the creation of HFC-23 and its 
emissions; (iii) identification of approved destruction technology and 
its location intended for use for HFC-23 destruction; and (iv) a copy 
of the DRE report associated with the destruction technology. EPA is 
further proposing that any changes to the information provided in the 
one-time report be reflected in a revision submitted to EPA within 60 
days of the change(s).
    EPA is also proposing to require annual reporting, to be submitted 
45 days after the control period, for production line data on HFC-23 
amounts: (i) Emitted; (ii) generated, whether captured or not; (iii) 
generated and captured for all uses; (iv) generated and captured for 
feedstock use in the United States; (v) generated and captured for 
destruction; (vi) used for feedstock without prior capture; and (vii) 
destroyed without prior capture. EPA is also soliciting comment on the 
frequency that this information should be submitted.
    If captured HFC-23 is destroyed in a subsequent control period 
(e.g., it is created and captured December 15 and destroyed January 15 
in the following year), EPA is further proposing to require the entity 
that produced the HFC-23 submit records indicating the HFC-23 has been 
destroyed within 45 days after destruction occurs.
    To ensure that reported values for HFC-23 generation, capture, 
transformation, and destruction are reliable, EPA is proposing to 
require entities to comply with certain monitoring and calculation 
provisions. Specifically, EPA is proposing to require entities to meet 
the same requirements as outlined in 40 CFR part 98, subpart

[[Page 27197]]

L or subpart OO, depending on the quantity being reported. These 
provisions include validated methods for measuring concentrations of 
HFC-23 in process streams and the mass flow rates of those streams; 
accuracy, precision, and calibration requirements for instrumentation; 
and specific calculation methods for uncontrolled emissions and for 
quantities transformed and destroyed. EPA proposes to include these 
reporting requirements to ensure that reported data are accurate, 
precise, and comparable over time and across facilities and companies.
Offramp
    Subsection (d)(1)(C) of the AIM Act specifies that reporting is no 
longer required if a company notifies EPA that they have permanently 
ceased production, import, export, destruction, transformation, use as 
a process agent, or reclamation of all regulated substances. Any 
activity that occurs earlier in that year before the cessation of 
activities must still be reported for that year.
Other
    Section (d)(1)(C)(iii) of the AIM Act states that each periodic 
report shall include, as applicable, the information described for the 
baseline period of 2011 through 2013. EPA interprets this provision as 
allowing the Agency to collect information necessary to establish the 
United States' production and consumption baselines. EPA reads the 
phrase ``as applicable'' to mean that every quarterly report does not 
need to reiterate that baseline information, only an initial report.
    EPA discusses in section V. of this preamble methods by which EPA 
has collected, and continues to collect, data from the relevant 
entities. As noted previously, once the baselines are established, EPA 
does not intend to amend the values and thus any reporting of baseline 
data would be unnecessary.

C. How is EPA proposing to coordinate AIM Act reporting with other EPA 
reporting requirements?

    Subsection (d)(2) of the AIM Act states that EPA may allow an 
entity subject to the AIM Act's reporting requirements ``to combine and 
include the information required to be reported under [the AIM Act] 
with any other related information that the [company] is required to 
report'' to EPA. This section of the notice will discuss which 
reporting requirements established under other authorities EPA is 
proposing to use instead of establishing new reporting obligations. EPA 
is soliciting comment on whether any or all of these reporting 
requirements should be established specifically under AIM Act authority 
in the regulations created through this rulemaking.
    Some of the data elements EPA is proposing to collect are similar 
to or the same as those required to be reported under the existing 
requirements associated with the GHGRP (40 CFR part 98, subparts L and 
OO). While the regulatory reporting requirements are separate, and EPA 
is not proposing any changes to 40 CFR part 98 in this rulemaking, EPA 
intends to coordinate reporting for similar or identical data elements 
by using the same online portal for submitting both AIM and GHGRP data 
(e-GGRT) and intends to reduce duplicative reporting by populating the 
annual report submitted under GHGRP with data submitted under the AIM 
Act. In the future, EPA would also consider harmonizing terms used 
under both programs or providing a document clarifying how the data 
collected under the AIM Act aligns with data collected under the GHGRP.

D. How does EPA propose to release HFC data collected under the AIM 
Act?

    In order to effectively implement an enforceable allowance 
allocation and trading program, proactively encourage compliance, and 
enable third-party engagement to complement EPA enforcement efforts, 
EPA is proposing several ways it intends to release data collected 
under this proposed rule. Some data would be released to the Ozone 
Secretariat at the United Nations Environment Programme and some data 
would be released to the general public. The Agency has noted below the 
intended audience for proposed data release. As a starting point, EPA 
notes that if a data point is collected under the GHGRP and is already 
released or determined under the GHGRP as not entitled to confidential 
treatment, and that same data point is required to be reported under 
these AIM Act regulations, it would not be given confidential treatment 
and would be considered releasable under these AIM Act regulations.\81\ 
Additionally, emission data, including data used as inputs to emissions 
equations, would generally be releasable under subsection (k)(1)(C), 
because of the AIM Act's statement in that subsection that CAA section 
114 applies to the AIM Act and any regulations promulgated under it as 
if the AIM Act were part of Title VI of the CAA. In particular, under 
subsection (k)(1)(C), CAA section 114(c), which provides that emission 
data shall be available to the public, applies to the AIM Act and any 
regulations promulgated under it.
---------------------------------------------------------------------------

    \81\ Nothing in this rulemaking is intended to change the 
regulations EPA has established determining how EPA will maintain 
data submitted in response to the GHGRP requirements. However, if 
EPA determines it can release the same data that is currently 
treated as CBI under the GHGRP, EPA would expect it could release 
such data under the GHGRP as well after making a change to the 
determination under the GHGRP consistent with 40 CFR 2.301(d)(4).
---------------------------------------------------------------------------

    To further support compliance efforts, in particular regarding 
illegal imports, EPA is proposing to release more data than it has 
historically released, some of which is currently determined to be CBI 
under the GHGRP.\82\ With respect to other data EPA is proposing to 
release, these data fall into several categories, including: Aggregated 
data that would not divulge information submitters customarily keep 
private or closely held; data to support the tracking and legal sale of 
HFCs sold in commerce; and data on allowance levels to support 
compliance and facilitate transfers of allowances.
---------------------------------------------------------------------------

    \82\ See ``Greenhouse Gas Reporting Program: Data Reported by 
Facilities Subject to the Supplier Subparts LL, through QQ, Geologic 
Sequestration Subject to Subpart RR*, and CO2 Injection 
Subject to Subpart UU,'' available at https://www.epa.gov/sites/production/files/2020-09/documents/ghgrp_cbi_tables_for_suppliers_8-28-20_clean_v3_508c.pdf.
---------------------------------------------------------------------------

1. Which general data elements does EPA propose to publicly release?
    Building on EPA's experience implementing the ODS phaseout under 
CAA Title VI, EPA is proposing to maximize transparency of the 
allocation program under the AIM Act. Market transparency would 
facilitate implementation of the allocation program and increase the 
public and current market participants' ability to provide 
complementary compliance assurances and pressure. It would allow the 
public and the industry to identify market participants and volumes in 
trade and thus enable them to alert EPA and other federal authorities 
when they suspect HFCs may have been produced, imported, or sold in 
violation of the regulations or of the AIM Act's prohibition in 
subsection (e)(2).
(a) Company-Level Production and Consumption Data
    As noted earlier, Congress has required that the Administrator 
``ensure that the annual quantity of all regulated substances produced 
or consumed in the United States does not exceed'' the annual caps 
described in subsection (e)(2)(B). To do that, EPA will need to employ 
many different compliance tools. Research shows that making data

[[Page 27198]]

publicly available facilitates compliance. Qualitative studies have 
found that ``public disclosure is [an] underutilized tool; there is 
powerful evidence that publishing information about company performance 
drives better behavior, as pressure is applied by customers, neighbors, 
investors, and insurers.'' \83\ EPA has also acknowledged the 
importance of data transparency in prior rulemakings. As the Agency 
explained in the preamble to a proposed rule (78 FR 46006, July 30, 
2013) concerning the National Pollutant Discharge Elimination System 
(NPDES):
---------------------------------------------------------------------------

    \83\ David Hindin and Jon Silberman, ``Designing More Effective 
Rules and Permits,'' George Washington Journal of Energy & 
Environmental Law, Spring 2016 at 103, 117-120.

    To promote transparency and accountability, EPA intends to make 
[a] more complete set of data available to the public, providing 
communities and citizens with easily accessible information on 
facility and government performance. Such data provides a powerful 
incentive to improve performance by giving government, permittees, 
and the public ready access to compliance information. This can 
serve to elevate the importance of compliance information and 
environmental performance within regulated entities, providing 
---------------------------------------------------------------------------
opportunity for them to quickly address any noncompliance.

    The same principles apply in this situation to incentivize 
compliance and allow the public and competing companies to identify and 
report noncompliance to EPA. To promote transparency and 
accountability, the Agency is taking comment on whether to release all 
HFC data, unaggregated and in a format similar to how it would be 
reported to EPA.\84\ This approach would allow for independent review 
of these data, in addition to the auditing and reporting requirements 
included in this proposal. EPA understands that many of the HFC supply 
data elements that would be released under this approach have 
previously been determined to be CBI (see, https://www.epa.gov/sites/production/files/2020-09/documents/ghgrp_cbi_tables_for_suppliers_8-28-20_clean_v3_508c.pdf),\85\ but still sees the value of releasing such 
data.
---------------------------------------------------------------------------

    \84\ If EPA finalizes an approach to release a data element 
collected through reporting required under the AIM Act, any of those 
same data elements collected under GHGRP would be made public and 
therefore would not be entitled to CBI protection regardless of any 
previous determinations made under GHGRP. EPA anticipates that it 
would subsequently make a corresponding change to the GHGRP CBI 
determinations in accordance with 40 CFR 2.301(d)(4).
    \85\ Many of the data elements reported to subpart OO of the 
GHGRP were determined to be, and are treated as, confidential by EPA 
(see e.g., 76 FR 30782, May 26, 2011; 76 FR 73886, November 29, 
2011; 77 FR 48072, August 13, 2012, 78 FR 71904, November 29, 2013; 
and, 81 FR 89188, December 9, 2016).
---------------------------------------------------------------------------

    Releasing all HFC activity (e.g., transfers, production data, 
transformation use) at the company and transaction level (e.g., 
chemical-specific production amounts) would be a significant divergence 
from past treatment of data under the GHGRP. Given the U.S. HFC market 
will have extensive regulation under the rulemakings implementing the 
AIM Act, it would be reasonable for EPA to take a different approach 
than has been taken for the GHGRP and release more disaggregated data 
than was released under those programs. Ensuring compliance with a 
regulatory phasedown program, where EPA is obligated to ensure that 
domestic production and consumption aligns with a statutorily defined 
schedule, is different than a reporting program where one company's 
noncompliance would mean less accurate accounting, but it does not have 
a statutorily defined target. It is reasonable for EPA to take all 
necessary steps to ensure that the Agency can ensure compliance with 
the consumption and production caps of subsection (e)(2)(B) as well as 
creating a level playing field.
    If we were to finalize this approach, companies would know that 
production and consumption information are not protected and therefore 
companies would not have a reasonable expectation that the information 
would be handled privately. Under recent Supreme Court case law, 
Exemption 4 of the Freedom of Information Act would not apply to 
information submitted with the expectation that the information would 
be made public. See Food Mktg. Inst. v. Argus Leader Media, 139 S. Ct. 
2356, 2360 (2019). Companies have a choice if they want to continue 
participating in the U.S. HFC market. EPA could also choose to release 
some elements such as transfer data since allowance holders and their 
allowance levels will be publicly available at the start of the year.
    As an alternative to the above proposal to release every data 
element reported to the Agency under the regulatory reporting structure 
being established through this rulemaking, EPA proposes to release any 
and all data elements that are publicly available through a range of 
datasets. Data that are already publicly available cannot be considered 
privately held or merit confidential treatment. EPA has not been able 
to identify a publicly available dataset on HFC production that is 
complete, although EPA's Chemical Data Registry does provide some HFC 
production and import data (https://chemview.epa.gov). EPA proposes to 
release any information that is already publicly available through 
EPA's Chemical Data Registry. EPA would not release production data 
collected through the reporting regulations established through this 
rulemaking, beyond what is available in the Chemical Data Registry, 
unless commenters identify a source where complete production data is 
available publicly.
    EPA is proposing to release all import data (e.g., transaction 
level shipment data) because EPA does not expect that release of these 
data would divulge information that is not already available through 
privately developed global trade databases.\86\ These databases charge 
a fee for access to information on imports at the transaction level 
based on Customs data from the United States and other countries, 
including bills of lading. There are also websites that provide 
selected import data at no cost.\87\ A submission available in the 
docket from First Continental International (NJ) Inc., dated March 12, 
2021, shows the types of information that can be ascertained from these 
databases. One of the key tests under the FOIA exemption in 40 CFR part 
2 regarding CBI is whether the data is available publicly elsewhere.
---------------------------------------------------------------------------

    \86\ Examples include PIERS (https://ihsmarkit.com/products/piers.html), Panjiva (https://panjiva.com), Datamyne (https://www.datamyne.com), and ImportGenius (https://www.importgenius.com). 
Mention of or referral to commercial products or services, and/or 
links to non-EPA sites does not imply official EPA endorsement of or 
responsibility for the opinions, ideas, data, or products presented 
at those locations, or guarantee the validity of the information 
provided. Mention of commercial products/services on non-EPA 
websites is provided solely as a pointer to information on topics 
related to environmental protection that may be useful to the public 
as they review this proposed rulemaking.
    \87\ Enigma, a data science firm, makes available online what 
appears to be the full Automated Manifest System import data from 
2018-2020, including the names of shipment consignees and cargo 
descriptions (https://aws.amazon.com/marketplace/pp/US-Imports-Automated-Manifest-System-AMS-Shipments/prodview-stk4wn3mbhx24). 
Similarly, usimports.info makes a limited number of import database 
queries free to users, allowing them to see data on individual bills 
of lading (https://usimports.info).
---------------------------------------------------------------------------

    Given import data is already publicly available, albeit behind a 
paywall, EPA is seeking comment on whether releasing import data 
collected under the AIM Act would divulge any additional information 
that could be claimed as CBI. Release of such data would also align 
with EPA's particular concern over imports of HFCs, where there is 
widespread global evidence of illegal activity, as outlined at the

[[Page 27199]]

beginning of section VIII of the preamble.
(b) Aggregated National Data
    As a separate alternative to the above-outlined approach, if EPA 
does not finalize to release all data elements to the public, EPA 
proposes to release all data that is already publicly available and 
otherwise to release certain aggregated HFC production and consumption 
data to the public. This approach would be similar to how EPA releases 
aggregated data collected pursuant to CAA Title VI authorities to 
implement the ODS phaseout. For example, as part of the ODS phaseout, 
EPA has released annual halon 1301 import, export, and petition data; 
\88\ aggregate inventory of pre-phaseout methyl bromide; aggregate 
annual HCFC consumption; and chemical-specific aggregated consumption 
for HCFC-22, HCFC-123, and HCFC-124, sometimes as an average over 
several years.\89\
---------------------------------------------------------------------------

    \88\ EPA has historically shared the amount of halon 1301 
imported and exported in a year, as well as the total quantity of 
material approved for import under the petition process described in 
40 CFR 82.13(g)(2). This information is shared via email with the 
interested stakeholder associations or posted to the EPA website 
(see https://www.epa.gov/ozone-layer-protection/halons-program 
(accessed February 14, 2021)).
    \89\ Aggregate HCFC data can be found in the United Nations 
Environment Programme's July 13, 2009, ``Workshop on management and 
destruction of ozone-depleting substance banks and implications for 
climate change,'' document, which can be found in the docket for 
this rulemaking.
---------------------------------------------------------------------------

    Releasing similar aggregated HFC data would allow EPA to document 
whether HFC consumption and production are at or below the levels 
prescribed in subsection (e)(2)(C), providing transparency to the 
public that EPA is meeting its statutory obligation. If aggregated data 
shows that actual values exceed those allowed under the phasedown 
schedule, it would highlight noncompliance with the requirements, and 
could encourage additional outside efforts to identify the cause of the 
exceedance, and to take further actions to ensure the caps are met. It 
would also provide insight into the ongoing transition out of specific 
HFCs, which might help inform future allocations of allowances and 
business planning for entities seeking allowances.
    For HFCs, EPA has already released certain aggregated data on the 
GHGRP website \90\ and through the recent NODA.\91\ These data include 
production minus destruction minus transformation; exports; imports; 
and net supply (CO2e quantities produced + imported-
exported-transformed-destroyed) for the 18 AIM Act-listed HFCs between 
2011 and 2019, as well as chemical-specific import data for HFC-134a, 
HFC-125, and HFC-32 for the same time period. The NODA also included a 
list of companies that produced (including those that destroyed), 
imported, and exported AIM Act-listed HFCs in 2011--2013. Other data 
elements that are released under the GHGRP are noted at https://www.epa.gov/sites/production/files/2020-09/documents/ghgrp_cbi_tables_for_suppliers_8-28-20_clean_v3_508c.pdf. EPA expects 
that release of the information in this subsection would not run any 
risk of divulging information submitters customarily keep private or 
closely held.

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

    EPA is proposing to release to the general public, without prior 
communication with the affected companies, chemical-specific 
information for HFCs where there are three or more reporting entities. 
This is the Agency's standard practice to mask information submitters 
customarily keep private or closely held. In such circumstances, a 
single reporter would know their own value but would not know how to 
apportion the remainder of the aggregated total among the other 
entities reporting. The proposed approach would be similar in that 
competitors would not be able to determine the relative share of each 
HFC with just the aggregated total. EPA proposes to release the EV-
weighted quantity as a way of masking company-specific data, as well as 
a list of the relevant HFCs.
    Under this separate alternate framework, EPA is proposing to 
release the following data annually in aggregated form in addition to 
any company or chemical specific information that is already publicly 
available:
     Total aggregated annual HFC production, EV-weighted;
     Total production by mass for each HFC;
     Total aggregated annual HFC consumption, EV-weighted;
     Total consumption by mass for each HFC;
     Total aggregated annual HFC imported, EV-weighted;
     Total imports by mass for each HFC;
     Total aggregated annual HFC exported, EV-weighted;
     Total exports by mass for each HFC;
     Total aggregated annual destruction (in kilograms) for 
each HFC;
     Annual aggregate amount of each HFC produced and imported 
(summed) for use as a feedstock by chemical; and
     Annual aggregate amount of each HFC produced and imported 
(summed) for use as a process agent, and aggregate annual emissions 
from such use by HFC.
    EPA would only release chemical-specific data without further 
consultation with the affected companies if it comprised data from 
three or more entities, if it was already publicly available, or if it 
was not claimed as CBI.
    The release of feedstock data could be useful to validate 
atmospheric measurements of HFCs, identify precursors and byproducts, 
and help inform decision making. Aggregated global data on production 
of ODS for feedstock use has been used for this purpose. EPA 
anticipates that publicly releasing feedstock data for HFCs could lead 
to similar benefits, while also providing additional transparency to 
the public on the ongoing use of HFCs that are being phased down under 
the AIM Act, but not phased out.
    EPA is not aware of current process agent use of HFCs and, as noted 
elsewhere, is seeking comment on which HFCs are used as a process 
agent, how the HFC is used as a process agent, which facilities use 
HFCs as a process agent, and the annual quantity of HFCs used as a 
process agent. If there were to be use of HFCs as process agents in 
sufficient quantities and frequencies to allow aggregation, EPA is 
proposing to release aggregated HFC process agent data.
    EPA is also proposing under this separate alternative approach to 
release aggregated annual consumption data associated with the use of 
application-specific allowances. Specifically, EPA would release total 
annual chemical-specific HFC consumption for each application, similar 
to how the Agency provided chemical-specific data in the market 
characterizations. Providing these data to the general public would 
allow EPA to show the scale of application-specific allowance use, 
identify where EPA's annual determination on the quantity of HFCs 
needed for the end use may need adjustment, and inform discussion in 
future rulemakings. This information would be aggregated across all 
application-specific allowance holders within a specific application, 
so EPA expects there would be no risk of divulging information 
submitters customarily keep private or closely held.
    Under this separate alternative approach, EPA is proposing to 
release

[[Page 27200]]

aggregated data on the quantity (in kilograms) of each HFC held in 
inventory as of December 31 of each year collectively by producers, 
importers, exporters, and reclaimers of HFCs. Analogous to the approach 
under CAA section 608, where almost all HFC reclamation data is 
released on a chemical-by-chemical basis, EPA is proposing to release 
HFC inventory by chemical. EPA would only release HFC-specific 
inventory values if there are three or more companies that have 
inventory of that HFC. Releasing inventory data can inform decisions of 
all companies in the marketplace. One motivator for this proposal is 
the experience with the phaseout of HCFC-22. Lack of reliable and 
widely distributed information on the scale of the existing inventory 
of HCFC-22 likely contributed to dramatic price swings associated with 
delays in the issuance of EPA allocation rulemakings. While additional 
information on inventory on its own may not prevent price fluctuations, 
the Agency expects it could provide more price predictability for the 
step-downs. Releasing inventory data could also help producers and 
importers make decisions about which HFCs are in short supply and/or 
could help support a smooth transition away from high-GWP HFCs.
(c) Company-Specific Allowance Data
    Separate and apart from the alternatives listed in the prior 
subsections, EPA is also proposing to publish on its website the names 
of every company receiving calendar-year production allowances, 
consumption allowances, or application-specific allowances. EPA would 
also publish the amount of allowances allocated at the beginning of the 
year to each company and revise that data quarterly as allowances are 
expended.
    Under the ODS phaseout program, EPA released similar company-
specific allowance data, including quantities produced or imported by 
each company in the baseline year by chemical and annual allocation 
amounts thereafter for nearly 30 years. EPA's experience has been that 
the release of this information has been important to reduce illegal 
imports, facilitate transfers, and provide third parties confidence 
that they were buying from a company that had allowances. EPA 
anticipates the same benefits would result from providing similar HFC 
data.
    In the case of HFCs, EPA is proposing to release an EV-weighted 
allowance value which would not divulge what HFC(s) a company is 
producing or consuming. Given this history and the fact that the data 
will be masked by being EV-weighted, EPA does not believe that 
producers or importers have a reasonable expectation of confidentiality 
concerning their allowance allocation levels.
(d) Transfer Data
    If EPA does not release all data, as described in section IX.D.1 of 
this preamble, EPA is also proposing to publish on the Agency's website 
certain aggregated data on transfers, so long as there are at least 
three companies involved in transferring allowances that year. 
Specifically, EPA is proposing to release data on the number of 
transfers, the total EV-weighted quantity of allowances transferred, 
and the average price of an allowance being transferred.
    Release of these data would provide the public with information on 
the frequency and scale of transfers associated with the HFC phasedown.
    While EPA sees value in releasing individual transfer data 
(excluding the price of the allowances transferred), the Agency expects 
that this would divulge information submitters customarily keep private 
or closely held. EPA seeks comment on this proposal, including whether 
submitters consider such data to be customarily kept private or closely 
held and whether EPA should release more data than just aggregate data.
(e) Information Relevant to the Kigali Amendment and the Montreal 
Protocol
    On January 27th, 2021, the President issued an Executive Order on 
Tackling the Climate Crisis at Home and Abroad (Executive Order 14008; 
86 FR 7619; January 27, 2021). Under part (j), the Executive Order 
directs the Secretary of State to prepare within 60 days a transmittal 
package seeking the Senate's advice and consent to ratification of the 
Kigali Amendment to the Montreal Protocol on Substances that Deplete 
the Ozone Layer. The Kigali Amendment requires an international 
phasedown of the production and consumption of HFCs. To ensure the 
United States would be prepared to comply with the data reporting 
elements of the Kigali Amendment, EPA is proposing that, if the United 
States were to join the Kigali Amendment, it would release data to the 
United Nations Environment Programme's Ozone Secretariat regarding HFC 
production, consumption, and limited emission data. With the exception 
of emission data related to the destruction of HFC-23, the data 
elements would be similar, if not identical, to those currently 
released for ODS. Should the United States join the Kigali Amendment, 
EPA will need to report \92\ the following data:
---------------------------------------------------------------------------

    \92\ The reporting forms and instructions that EPA would use to 
submit such data are available in the docket and on the Ozone 
Secretariat's website at https://ozone.unep.org/countries/data-reporting-tools (accessed February 14, 2021).
---------------------------------------------------------------------------

     Annual U.S. HFC production in MT by chemical for each of 
the HFCs listed in subsection (c) of the AIM Act, including total HFC 
production for all uses and HFC production for feedstock in the United 
States;
     Annual U.S. HFC import in MT aggregated by chemical and by 
country imported from for each of the HFCs listed in subsection (c) of 
the AIM Act, including the amount that was new (virgin), recovered and 
reclaimed, or for feedstock use;
     Annual U.S. HFC export in MT aggregated by chemical and by 
country exported to for each of the HFCs listed in subsection (c) of 
the AIM Act, including the amount that was new (virgin), recovered and 
reclaimed, or for feedstock use;
     Annual U.S. HFC destruction in MT aggregated by chemical 
for each of the HFCs listed in subsection (c) of the AIM Act; and
     Annual facility-level information on HFC-23 generated and 
destroyed, including annual amounts of HFC-23:
    [cir] Generated, whether captured or not;
    [cir] generated and captured for all uses;
    [cir] generated and captured for feedstock use in the United 
States;
    [cir] generated and captured for destruction;
    [cir] used for feedstock without prior capture;
    [cir] destroyed without prior capture; and
    [cir] generated emissions.
    Regarding annual facility-level information on HFC-23 generated and 
destroyed, these data are inputs into emission equations that are used 
under GHGRP subparts L and O to calculate and report emissions of HFC-
23, and inputs into emission equations may be considered ``emission 
data.'' Section 114(c) of the CAA provides that ``emission data'' shall 
be available to the public. As noted above, because subsection 
(k)(1)(C) of the AIM Act states that section 114 of the CAA applies to 
the AIM Act and rules promulgated under it as if the AIM Act were 
included in Title VI of the CAA, the requirements under section 114(c) 
of the CAA that apply to ``emission data'' also apply to data gathered 
under the AIM Act that are determined to be ``emission data.'' EPA is 
proposing to determine that these elements related to HFC-23 are 
emission data and thus

[[Page 27201]]

would not be treated as confidential under this rule.
    The Ozone Secretariat would release aggregated GWP-weighted annual 
production and consumption on the Ozone Secretariat's website.\93\ 
Additional data elements released include annual amounts destroyed, 
aggregated for all reported chemicals under the Montreal Protocol in 
MT, import of recovered/recycled/reclaimed substances by group (e.g., 
HFCs) in MT, and export of recovered/recycled/reclaimed substances in 
MT by group. Should the United States join the Kigali Amendment, EPA 
would also need to submit chemical-specific production and consumption 
data consistent with the data listed for 2011, 2012, and 2013 to 
establish the United States' baseline for HFCs.
---------------------------------------------------------------------------

    \93\ The Ozone Secretariat's handling of similarly reported data 
from the United States on ODS is available at https://ozone.unep.org/countries/profile/usa.
---------------------------------------------------------------------------

    The Parties to the Montreal Protocol adopted Decision I/11 \94\ 
during the First Meeting of the Parties, which outlines the Parties' 
view on how to treat the confidentiality of data submitted to the Ozone 
Secretariat. In accordance with the decision, if the United States is 
submitting data that it has determined to be entitled to confidential 
treatment, the United States has the ability to mark the data 
accordingly such that it will be treated with secrecy and maintained 
confidential by the Secretariat. EPA intends to mark any data that the 
Agency is not releasing to the general public for confidential 
treatment in its annual reporting, were the United States to join the 
Kigali Amendment. The decision requests the Ozone Secretariat to only 
release aggregated data such that any data a Party to the Protocol 
considers to be confidential will not be disclosed. However, Parties to 
the Protocol may exercise their right under Article 12, paragraph b of 
the Protocol to have access to confidential data from other parties, 
provided that they send an application in writing that guarantees such 
data will be treated with secrecy and not disclosed or published in any 
way.

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

    EPA conducted a Regulatory Impact Analysis 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 this rule. This 
analysis is intended to provide the public with information on the 
relevant costs and benefits of this action and to comply with Executive 
Orders.
    EPA estimates that in 2022 the annual net benefits are $2.6 
billion, reflecting compliance costs of $200 million and social 
benefits of $2.8 billion. In 2036, when the final phasedown step is 
reached at 15 percent of the statutorily defined HFC baseline, the 
estimated annual net benefits are $17.9 billion. Table 5 presents a 
summary of the annual costs and net benefits of the rule for selected 
years in the time period 2022-2050, but with the climate benefits 
discounted at 3%.

\a\ Benefits include only those related to climate. Climate benefits are based on changes (reductions) in HFC
  emissions and are calculated using four different estimates of the social cost of HFCs (SC-HFCs) (model
  average at 2.5 percent, 3 percent, and 5 percent discount rates; and 95th percentile at 3 percent discount
  rate). For the presentational purposes of this table, we show the benefits associated with the average SC-HFC
  at a 3 percent discount rate, but the Agency does not have a single central SC-HFC point estimate. We
  emphasize the importance and value of considering the benefits calculated using all four SC-HFC estimates. See
  Table 4-20 in the RIA for the full range of SC-HFC estimates. As discussed in Chapter 4 of the RIA, a
  consideration of climate benefits calculated using discount rates below 3 percent, including 2 percent and
  lower, are also warranted when discounting intergenerational impacts. The costs presented in this table are
  annual estimates.
\b\ Rows may not appear to add correctly due to rounding.

and 2050.

\a\ Climate benefits are based on changes (reductions) in HFC emissions and are calculated using four different
  estimates of the social cost of HFCs (SC-HFCs) (model average at 2.5 percent, 3 percent, and 5 percent
  discount rates; and 95th percentile at 3 percent discount rate). The IWG emphasized the importance and value
  of considering the benefits calculated using all four estimates. As discussed in the Technical Support
  Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates under Executive Order 13990 (IWG
  2021), a consideration of climate benefits calculated using discount rates below 3 percent, including 2
  percent and lower, are also warranted when discounting intergenerational impacts.

    EPA estimates that the present value of cumulative net benefits 
evaluated from 2022 through 2050 is $283.9 billion at a three percent 
discount rate, comprising $272.8 billion in cumulative benefits due to 
reducing HFC emissions and $11.1 billion in cumulative compliance 
savings. The present value of net benefits is calculated over the 29-
year period from 2022-2050, to account for the years that emissions 
will be reduced following the consumption reductions from 2022-2036. 
Over the 15-year period of the phasedown of HFCs, the present value of 
cumulative compliance costs is negative $5 billion, or $5 billion in 
savings, and the present value of cumulative social benefits is $103.6 
billion, both at a three percent discount rate. Over the same 15-year 
period of the phasedown, the present value of cumulative net benefits 
is $108.2 billion. At a 7% discount rate over the 15-year period of the 
phasedown of HFCs, the present value of cumulative compliance costs is 
negative $3billion, or $3 billion in savings. Over the same 15-year 
period of the phasedown, the present value of cumulative net benefits 
is $106.6 billion at a 7% discount rate for costs (and 3% for climate 
benefits). The comparison of benefits and costs in PV and EAV terms for 
the rule can be found in Table 7. Estimates in the table are presented 
as rounded values.

\b\ The annualized present value of costs and benefits are calculated over a 29-year period from 2022 to 2050.
\c\ Climate benefits are based on changes (reductions) in HFC emissions and are calculated using four different
  estimates of the social cost of HFCs (SC-HFC) (model average at 2.5 percent, 3 percent, and 5 percent discount
  rates; and 95th percentile at 3 percent discount rate). For purposes of this table, we show the benefits
  (climate benefits and net benefits) associated with the model average at a 3 percent discount rate, but the
  Agency does not have a single central SC-HFC point estimate. We emphasize the importance and value of
  considering the benefits calculated using all four SC-HFC estimates. As discussed in Chapter 4 of the RIA, a
  consideration of climate benefits calculated using discount rates below 3 percent, including 2 percent and
  lower, are also warranted when discounting intergenerational impacts.
\d\ The costs presented in this table are consistent with the costs presented in RIA Chapter 3, Table 3-5.

    The estimation of $272.8 billion in benefits due to reducing HFC 
emissions involved three steps. First, the difference between the 
consumption of HFCs allowed under the rule and the consumption that 
would have been expected in a business-as-usual scenario (BAU) was 
calculated for each year of the phasedown in exchange value-weighted 
tons (EVe). Second, using EPA's Vintaging Model, the changes in 
consumption were used to estimate changes in HFC emissions, which 
generally lag consumption by some time as HFCs incorporated into 
equipment and products are eventually released to the environment. 
Finally, the climate benefits were calculated by multiplying the HFC 
emission reductions for each year by the appropriate social cost of HFC 
to arrive at the monetary value of HFC emission reductions.
    EPA estimates the climate benefits for this proposed rulemaking 
using a measure of the social cost of each HFC (collectively referred 
to as SC-HFC) that is affected by the rule. The SC-HFC is the monetary 
value of the net harm to society associated with a marginal increase in 
HFC emissions in a given year, or the benefit of avoiding that 
increase. In principle, SC-HFC includes the value of all climate change 
impacts, including (but not limited to) changes in net agricultural 
productivity, human health effects, property damage from increased 
flood risk and natural disasters, disruption of energy systems, risk of 
conflict, environmental migration, and the value of ecosystem services. 
The SC-HFC, therefore, reflects the societal value of reducing 
emissions of the gas in question by one metric ton. The SC-HFC is the 
theoretically appropriate value to use in conducting benefit-cost 
analyses of policies that affect HFC emissions. The Interagency Working 
Group on the Social Cost of Greenhouse Gases (IWG) will be taking 
comment on how to incorporate the recommendations of the National 
Academies (2017) and other recent science including the advances 
discussed in the 2021 TSD in the development of the fully updated SC-
GHG estimates to be released by January 2022 under E.O. 13990. To 
complement the IWG process, and as an active member of the IWG, EPA is 
soliciting comment in this proposed rule on the SC-HFC estimates used 
in this RIA and the methodology underlying them,

[[Page 27203]]

including on how that methodology should be adapted in future to 
accommodate advances in the scientific and economic literature. 
Additional benefits are derived by requiring a five-percent offset for 
allowance transfers, which decreases the cap of the total allowable 
HFCs in the system. EPA is also taking comment on the RIA, which is 
included in the docket. The public is invited to provide comment and/or 
data that would inform various analytic matters and uncertainties in 
the RIA (see Executive Summary and Chapter 7 of the RIA).

XI. What should EPA consider in future rulemakings?

    In addition to the proposals included in this rulemaking, EPA is 
also providing advance notice and seeking input on how the Agency 
should determine company-specific allocations in 2024 and later years. 
Given high baseline health risks related to air toxics in communities 
near facilities that produce HFCs and potential environmental justice 
concerns, EPA is also seeking input on ways to ensure that these 
elevated risks not be further exacerbated by changes in the use 
patterns for production of HFCs or their substitutes. Since these 
topics relate to future rulemaking, rather than proposals in this 
rulemaking, EPA will take comments on this section under advisement and 
incorporate them, as appropriate, into such future rulemakings, with an 
opportunity for public comment prior to finalization of any provisions.

A. How should EPA consider future allowance allocations?

    The AIM Act requires a phasedown of HFC production and consumption 
to 15 percent of baseline by 2036 with no further lowering of the cap. 
This is in contrast to the approach for ODS, where production and 
consumption of chemicals were phased out, with limited exceptions. As 
such, EPA is considering whether a different approach is warranted for 
determining allowance allocations under the AIM Act and is seeking 
advance input on several options for the allowance framework and 
procedure for 2024 and later years.
    For ODS, EPA generally issued allowances to a set of companies 
based on their historic levels of production and consumption. Given the 
intent was to phase out the production and consumption of ODS, EPA did 
not adjust the list of allowance holders once they were set, except to 
reflect transfers of baseline allowances between companies. EPA is 
considering whether allocating HFC allowances largely to historic 
producers or importers is appropriate in the long-term for a phasedown.
    EPA is particularly interested in whether the concepts presented in 
this section would benefit the environment (e.g., by encouraging 
transition to low-GWP and non-HFC substances); provide an incentive or 
disincentive to companies that develop and introduce low-GWP and non-
HFC substances; support the effective functioning of the HFC production 
and import market; and/or create or remove barriers to new entrants to 
the market, including for socially and economically disadvantaged 
individuals. EPA seeks advance input on the following concepts, as well 
as suggestions for additional approaches the Agency could consider for 
2024 \95\ and later years.
---------------------------------------------------------------------------

    \95\ 2024 is the next milestone under the AIM Act phasedown 
schedule, when aggregate allowances must be reduced to 60 percent of 
the baseline.
---------------------------------------------------------------------------

    (1) Allocating allowances based on past production and consumption 
from a set period of years and only adjusting allowance holders to 
reflect transfers between companies;
    (2) Allocating allowances based on a reevaluation of the most 
recent years of production and consumption data as reported to EPA 
(e.g., three years);
    (3) Allocating allowances based on past production and consumption, 
but requiring a fee for every allowance provided for production or 
import of HFCs;
    (4) Establishing an auction system for the total set, or some 
subset, of generally available allowances;
    (5) A combination of the above approaches, such as phasing in the 
use of an auction or fee over time.
    Under the first concept, EPA would continue to issue allowances at 
no cost. While there would be no cost associated with the allowances, 
the allowances have value. Companies that receive allowances could 
choose to remain in the market and produce or import HFCs, sell or 
otherwise transfer their allowances to another company, or retire their 
allowances. New entrants, other than those potentially established 
through this rulemaking, would typically have to buy into the market 
through the purchase of allowances. This approach may provide the least 
flexibility for new entrants, and is most consistent with past practice 
phasing out ODS. It would also provide ongoing value to companies 
already in the market through the issuance of allowances regardless of 
whether they continue to produce or import HFCs, effectively at the 
expense of other allowance holders who are actively producing or 
importing.
    The second concept would be similar in many respects to the first, 
but would adjust each company's share of allowances periodically--
either at phasedown steps or every few years. It would reflect 
transfers periodically when EPA adjusted the years of production and 
consumption considered in allocating allowances, and would require new 
entrants, after this initial allocation rule, to purchase or otherwise 
obtain allowances from another allowance holder to enter the market 
(although such new entrants may be included in future allocations after 
the years considered shifted). This approach may better ensure the 
companies receiving allowances are the companies who are actively 
producing and importing. EPA can see advantages to this approach, 
particularly for companies that continue to produce HFCs in the United 
States, since allowances associated with companies that stop domestic 
production would periodically be reapportioned to companies that 
continue to produce domestically. However, this approach would 
encourage companies to use all of their allowances or lose them at the 
next periodic adjustment, potentially resulting in production and 
consumption at a higher level than the market would demand. This could 
also have environmental consequences if more HFCs are produced and 
imported than are needed to satisfy market demand.
    The third concept would adopt an approach similar to the first two, 
but would require companies pay a fee for allowances provided for 
production or import of HFCs. This could address concerns about 
producing or importing more HFCs than a company expects to need, 
potentially resulting in benefits for the environment, but could 
increase the cost of the allowance allocation and trading program. 
Additionally, depending on how the fee was structured, this concept 
could favor companies with more access to capital to purchase the 
allowances. Given the expected increase in the market price of HFCs 
that is likely to occur over time as allowances decrease, EPA would not 
expect this to affect companies' profitability, but it could increase 
the cost of HFCs. An increase in the cost of HFCs could foster faster 
transition to alternatives, which would result in additional 
environmental benefits. By increasing the cost of virgin material, it 
could also increase the profitability and use of reclaimed material. As 
noted previously, reclamation will be an important component to a 
smooth

[[Page 27204]]

transition from HFCs, as it has been in past ODS phaseouts. It could 
also foster a more active allowance transfer market to the extent 
companies determine they have excess allowances that would earn more 
profit if transferred to companies that are seeking additional 
allowances based on their customers' demands.
    Under the fourth concept, EPA would determine the total allocation 
level and establish an auction system for individual allowances. This 
approach would provide flexibility in the marketplace such that 
producers and importers could adjust their allowances from year-to-
year. This approach may allow the broadest participation in the HFC 
production and import market. It could have similar benefits for the 
environment by adding an extra cost to using an allowance and 
discouraging entities from seeking allowances where there isn't 
corresponding market demand. Increases in the price of virgin HFCs 
could encourage transition to alternatives and support the use of 
reclaimed material. Under an auction, EPA could consider developing a 
mechanism that would permit entities to purchase allowances for the 
purpose of retiring them which could result in additional environmental 
benefits. The Agency seeks advance input on how best to structure such 
an auction program, so as not to discourage participation by small 
businesses and businesses that are socially and economically 
disadvantaged. Smaller business may not have as much access to capital 
and could potentially be shut out of the HFC production and import 
market if the auction price was too high. This approach may also have 
administrative challenges, but EPA could rely on its experience 
implementing other environmental auction programs to set up and 
administer such a program.
    The fifth concept would be a combination of any of the other 
concepts, including allowing for future new entrants pools similar to 
the one described in the proposal. In particular, EPA is interested in 
whether it would be appropriate to phase in the third or fourth 
concepts over time. For example, allowances in the early years of the 
phasedown could be primarily allocated to companies that are currently 
producing and importing (under the first two concepts), but each year 
EPA could increase the share of allowances that are subject to a fee or 
put up for auction. Under this approach, EPA could envision all 
allowances being subject to a fee or put up for auction by 2036 when 
the final phasedown step under the AIM Act is reached. This would 
gradually transition the market from receiving allowances based on 
historic production and import to one where any company could enter the 
market.
    EPA is seeking advance input on these and other approaches for 
issuing allowances starting with 2024.

B. How should EPA address the potential health effects of air toxics 
associated with changes in the production of HFCS and substitutes in a 
future rulemaking?

    Section III of the preamble describes EPA's initial approach in 
assessing potential environmental justice concerns and poses several 
questions designed to inform the Agency's analysis. The Agency's 
preliminary screening-level analysis is included in the RIA, available 
in the docket associated with this rulemaking. EPA is evaluating 
whether there may be inadvertent or unexpected distributional effects 
of the phasedown of HFCs that may cause potential environmental justice 
concerns. Specifically, chemical feedstocks and byproducts emitted as 
part of the production process at a facility expending allowances, or 
producing substitutes, may cause or contribute to disproportionately 
high exposure to certain air toxics in communities adjacent to, or 
surrounding, that facility. As noted above, there is uncertainty about 
how this rule would change production of HFCs and substitutes at 
individual facilities, and how any such changes might affect air toxics 
emissions and exposure in nearby communities.
    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 (i.e., effects resulting from the phasedown itself, the trading 
of production allowances, or some other factor) to 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 is also seeking comment on whether 
there are other regulatory tools better suited than adjustments to the 
HFC program design to address potential increases in emissions in non-
HFC feedstocks and byproducts at facilities subject to the 
Congressionally mandated phasedown of HFCs under the AIM Act, if any. 
EPA also seeks comment on whether these are the appropriate questions 
or if there are other questions the Agency should be asking. EPA is 
also soliciting comment on key assumptions underlying the environmental 
justice analysis.
    EPA is also seeking input on the following approaches for future 
rulemaking with respect to how the Agency treats allowance transfers to 
address any potential for increased air toxics exposure in at-risk 
communities, and the Agency is also seeking input on other approaches 
that we have not considered.
1. Adjustments to Transfer Offsets
    EPA could consider adjusting the transfer offset, currently 
proposed at five-percent (and taking comment on one to 10 percent), 
based on factors such as the location of the receiving facility and 
projected impacts to the surrounding community.
2. Issuing Allowances at a Facility Level
    EPA's current proposal is to issue allowances at a company level, 
but the Agency could consider issuing allowances at a facility level in 
future rulemakings to limit the potential for disproportionately high 
production of HFCs.
3. Release of Relevant Facility Data
    As part of an allowance transfer request, EPA could require the 
company receiving allowances to submit relevant facility data, which 
would be made available to the public, that is sufficient to 
demonstrate that transfers of allowances would not increase risks in 
communities with high existing air toxic emissions or elevated health 
risks.

XII. 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 
is the Summary of this 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 Number EPA-HQ-OAR-2021-
0044.

B. Paperwork Reduction Act (PRA)

    The information collection activities in this proposed rule will be 
submitted for approval to the Office of

[[Page 27205]]

Management and Budget (OMB) under the PRA upon publication of this 
proposed rule. The Information Collection Request (ICR) document that 
EPA prepared has been assigned EPA ICR number 2685.01. You can find a 
copy of the ICR in the docket for this rule, 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 company 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 company: 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 is proposing to collect such data regularly to 
support implementation of the AIM Act's HFC phasedown provisions. EPA 
is proposing 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 is 
proposing to collect information in order to calculate allowances, to 
track the movement of HFCs through commerce, and to require auditing. 
Collecting these data elements would allow for 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.
    All information sent by the submitter electronically is transmitted 
securely to protect information submitters customarily keep private or 
closely held. The reporting tool guides the user through the process of 
submitting CBI. Documents containing information claimed as CBI must be 
submitted in an electronic format, in accordance with the recordkeeping 
requirements. EPA also allows respondents to report CBI by fax and 
through courier.
    Respondents/affected entities: Respondents and affected entities 
will be individuals or companies 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 companies 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: 11,664.
    Frequency of response: Quarterly, biannual, annual, and as needed 
depending on the nature of the report.
    Total estimated burden: 36,540 hours (per year). Burden is defined 
at 5 CFR 1320.3(b).
    Total estimated cost: $4,506,092 per year, includes $24,100 
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. You may also send your ICR-related comments to 
OMB's Office of Information and Regulatory Affairs via email to 
OIRA_submission@omb.eop.gov, Attention: Desk Officer for EPA. Since OMB 
is required to make a decision concerning the ICR between 30 and 60 
days after receipt, OMB must receive comments no later than June 18, 
2021. EPA will respond to any ICR-related comments in the final rule.
    EPA used data collected under the ICR for the Greenhouse Gas 
Reporting Program (OMB Control No. 2060-0629) as well as the associated 
reporting tool, the electronic Greenhouse Gas Reporting Tool (e-GGRT) 
in developing this proposed rulemaking. EPA has also requested an 
emergency ICR for a one-time collection request pertaining to data 
necessary to establish the United States 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).

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. The 
small entities subject to the requirements of this action are suppliers 
of HFCs including producers, importers, exporters, reclaimers, 
companies that destroy HFCs, and companies that sell and distribute 
HFCs. Details of this analysis are presented in ``Economic Impact 
Screening Analysis for Proposed Allowance System for an HFC Production 
and Consumption Phasedown.'' Docket ID EPA-HQ-OAR-2021-0044.
    The Regulatory Flexibility Act (RFA) generally requires an agency 
to prepare a regulatory flexibility analysis of any rule subject to 
notice-and-comment rulemaking requirements under the Administrative 
Procedure Act or any other statute unless the agency certifies that the 
rule will not have a significant economic impact on a substantial 
number of small entities (SISNOSE). Small entities include small 
businesses, small organizations, and small governmental jurisdictions. 
For purposes of assessing the impacts of this rule on small entities, 
small entity is defined as: (1) A small business as defined by the U.S. 
Small Business Administration's (SBA) regulations at 13 CFR 121.201; 
(2) a small governmental jurisdiction that is a government of a city, 
county, town, school district, or special district with a population of 
less than 50,000; or (3) a small organization that is any not-for-
profit enterprise that is independently owned and operated and is not 
dominant in its field.
    If a rule may have a SISNOSE, the Agency would be required to take 
certain steps to ensure that the interests of small entities were 
represented in the rulemaking process. To determine whether this 
proposed rule would likely have a significant economic impact on a 
substantial number of small entities (SISNOSE), EPA identified 
producers, importers, exporters, and reclaimers of HFCs from 2018 and 
2019 that reported to EPA's Greenhouse Gas Reporting Program and the 
U.S. Customs and Border Protection Automated Commercial Environment 
(ACE). Available economic data about each identified entity (i.e., 
number of employees, annual sales) were obtained from the Dun and 
Bradstreet databases, and the sizes compared with the U.S. Small 
Business Administration's table of small business size standards 
matched to NAICS codes. The small business threshold is defined by SBA 
as the number of employees in the

[[Page 27206]]

company and varied between 100 and 1,500 employees. There were 
identified HFC importers and reclaimers that met the definition of 
small businesses, but no HFC producers were identified as small 
businesses. To determine the likely economic impact on these small 
businesses, it was assumed that a percentage of the HFCs they imported 
would be replaced by an alternative, and the difference in the price 
between the HFCs and their alternatives was applied to determine any 
change in sales revenue. The methods used and assumptions made to 
perform this analysis are described in detail in the technical support 
document, Economic Impact Screening Analysis for Proposed Allowance 
System for an HFC Production and Consumption Phasedown, found in the 
docket of this proposed rule.
    EPA estimates that approximately 9 of the 8,746 potentially 
affected small businesses could incur costs in excess of one percent of 
annual sales and that approximately 4 small businesses could incur 
costs in excess of three percent of annual sales. Because these levels 
are below the thresholds used in EPA's other rulemakings affecting 
these industries (e.g., CAA Title VI rulemakings), it can be presumed 
that this action will have no SISNOSE.

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 will 
share 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 will 
further improve children's health. The assessment literature cited in 
EPA's 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)

    This rulemaking does not involve technical standards.

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

    This rule will 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 
minority populations, low-income populations and/or indigenous peoples. 
However, EPA is not yet able 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). A summary of the 
Agency's approach for considering potential environmental justice 
concerns as a result of this rulemaking can be found in section III of 
the preamble, and our environmental justice analysis can be found in 
the RIA, available in the docket for this rulemaking.

Appendix A to Part 84--Regulated Substances

    Authority: Section 103 in Division S, Innovation for the 
Environment, of the Consolidated Appropriations Act, 2021 (Pub. L. 
116-260).

Subpart A--Production and Consumption Controls

Sec.  84.1  Purpose and scope.

    (a) The purpose of the regulations in this subpart is to implement 
the American Innovation and Manufacturing Act of 2020 (AIM Act), 
enacted as part of Public Law 116-260. The AIM Act imposes limits on 
the production and consumption of certain regulated substances, 
according to a specified schedule.
    (b) This subpart applies to any person that produces, transforms, 
destroys, imports, exports, distributes, or reclaims a regulated 
substance and to end users in the six applications listed in subsection 
(e)(4)(B)(iv) of the AIM Act.

Sec.  84.3  Definitions.

    As used in this subpart, the term:
    Administrator means the Administrator of the United States 
Environmental Protection Agency or his or her authorized 
representative. Reports and petitions, as well as any related 
supporting documents, must be submitted electronically in a format 
specified by the Administrator.
    Allowance means a limited authorization for the production or 
consumption of a regulated substance established under subsection (e) 
of section 103 in Division S, Innovation for the Environment, of the 
Consolidated Appropriations Act, 2021 (Pub. L. 116-260) (the AIM Act). 
An allowance allocated under subsection (e) of section 103 in Division 
S of the AIM Act does not constitute a property right and can be 
retired, revoked, or withheld at the discretion of the relevant Agency 
official.
    Application-specific allowance means a limited authorization 
granted in accordance with subsection (e)(4)(B)(iv) of the AIM Act for 
the production or import of a regulated substance for use in the 
specifically identified applications that are listed in that subsection 
and in accordance with the restrictions contained at Sec.  84.5(c). An 
application-specific allowance does not constitute a property right and 
can be retired, revoked, or withheld at the discretion of the relevant 
Agency official.
    Bulk means 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,

Sec.  84.5  Prohibitions for regulated substances.

    (a) Production. (1) Effective January 1, 2022, no person may 
produce regulated substances, intentionally or unintentionally, in 
excess of the quantity of unexpended production allowances or 
unexpended application-specific allowances held by that person under 
the authority of this subpart at that time in that control period. 
Every kilogram of production in excess of allowances expended 
constitutes a separate violation of this subpart.
    (2) Effective January 1, 2022, no person may use production 
allowances to produce a quantity of regulated substances unless that 
person uses an equal quantity of consumption allowances at the same 
time.
    (3) A person is not required to expend production allowances or 
application-specific allowances to produce regulated substances if the 
regulated substances are destroyed using a technology approved by the 
Administrator for destruction under Sec.  84.29 within 30 days if the 
destruction technology is located at the facility where production 
occurred or 90 days if the destruction technology is not located at the 
facility where production occurred.
    (b) Import. Effective January 1, 2022, (1) No person may import 
bulk regulated substances, except:
    (i) By 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;
    (ii) After receipt of a non-objection notice for substances for use 
in a process resulting in their transformation or their destruction in 
accordance with Sec.  84.25(a);
    (iii) After receipt of a non-objection notice for used regulated 
substances imported for destruction in accordance with Sec.  84.25(b); 
or
    (iv) As a transhipment in accordance with Sec.  84.31(c)(3) if all 
transhipped regulated substance leaves the country within six months of 
its entry.
    (2) Imports authorized under paragraph (b)(1)(ii) of this section 
may not be in containers designed to hold 100 pounds or less of a 
regulated substance.
    (3) A person issued a non-objection notice for the import of an 
individual shipment of regulated substances under paragraphs (b)(1)(ii) 
and (iii) of this section may not transfer or confer the right to 
import.
    (4) No person may introduce into interstate commerce any regulated 
substance claimed as a transhipment and/or held in a bonded warehouse 
while in transit.
    (5) Every kilogram of bulk regulated substances imported contrary 
to this paragraph (b) constitutes a separate violation of this subpart.
    (c) Application-specific uses. (1) Effective January 1, 2022, no 
person may confer application-specific allowances for the production or 
import of a regulated substance in excess of the amount of unexpended 
application-specific allowances held by that person under the authority 
of this subpart at that time in that control period. No person may 
expend an application-specific allowance for regulated substances to be 
used in any application other than the one identified by the 
application-specific allocation expended. Every kilogram of production 
in excess of the application-specific allowances expended by the 
producer constitutes a separate violation of this subpart. Every 
kilogram of import in excess of the application-specific allowances 
expended by the importer constitutes a separate violation of this 
subpart.
    (2) No person may use a regulated substance produced or imported 
using application-specific allowances for any purpose other than those 
for which the application-specific allowance was allocated, and as set 
forth in this paragraph (c). Application-specific allowances are 
apportioned to a person under Sec. Sec.  84.13 and 84.15 for the 
production or import of regulated substances solely for the individual 
application listed on the allowance, which may include:
    (i) A propellant in metered dose inhalers;
    (ii) Defense sprays;
    (iii) Structural composite preformed polyurethane foam for marine 
use and trailer use;

application-specific allowances unless for use in the same application 
as associated with the application-specific allowance. No person may 
transfer application-specific allowances unless for use in the same 
application as associated with the application-specific allowance.
    (ii) No person may acquire or sell regulated substances produced or 
imported using application-specific allowances for use in anything 
other than the application for which it was originally allocated. Every 
kilogram of a regulated substance imported or exported in contravention 
of this paragraph constitutes a separate violation of this subpart.
    (d) International transfers. Effective January 1, 2022. (1) no 
person subject to the requirements of this subpart may transfer a 
production allowance to a person in a foreign country unless that 
country has established the same or similar requirements or otherwise 
undertaken commitments regarding the production and consumption of 
regulated substances as are contained in the AIM Act, as determined by 
the EPA.
    (2) Similarly, no person may transfer production allowances to or 
from a person in a foreign country without satisfying the requirements 
in Sec.  84.19. Every production allowance transferred in contravention 
of this paragraph constitutes a separate violation of this subpart.
    (e) Violations. No person may sell or distribute, or offer for sale 
or distribution, any regulated substance that was produced or imported 
in violation of paragraphs (a) through (d) of this section, except for 
such actions needed to re-export the regulated substance. Every 
kilogram of a regulated substance sold or distributed, or offered for 
sale or distribution, in contravention of this paragraph constitutes a 
separate violation of this subpart.
    (f) False information. No person may provide false information to 
the EPA when petitioning, reporting, or for any

[[Page 27210]]

communication required under this subpart.
    (g) Agency actions. The Agency has full discretion to retire, 
revoke, or withhold the allocation of allowances for actions in 
contravention of this part.
    (h) Anti-Dumping/Countervailing Duties. The relevant Agency 
official reserves the right to retire, revoke, or withhold the 
allocation of allowances to any otherwise qualifying importer that is 
in arrears with Anti-Dumping/Countervailing Duties required under a 
final determination from the Department of Commerce.
    (i) Disposable cylinders. (1) Effective July 1, 2023, no person may 
import or place a regulated substance in a non-refillable cylinder.
    (2) Effective January 1, 2025, no person may sell or offer for sale 
regulated substances contained in a non-refillable cylinder.
    (3) Small cans containing less than two pounds of regulated 
substances that utilize a self-sealing valve that meets the 
requirements in 40 CFR 82.154(c)(2) are not subject to this 
restriction.
    (j) Labeling. (1) Effective January 1, 2022, no person may sell or 
distribute, or offer to sell or distribute, containers containing a 
regulated substance that lacks a label or other permanent markings, in 
numbers and letters at least \1/8\ inch high, stating the common name 
of the regulated substances or blend contained, the composition and 
ratios of the regulated substances if a blend, and a cylinder serial 
number.
    (2) No person other than the importer may repackage material that 
was initially unlabeled or mislabeled unless the importer:
    (i) Expends consumption allowances equal to the amount of 
allowances that would be required if each cylinder were full of HFC-23; 
or
    (ii) Verifies the contents with independent laboratory testing 
results and fixes a label on the container conveying the lab-verified 
test results before the container enters interstate commerce.

Sec.  84.9  Allocation of calendar-year production allowances.

    (a) EPA will issue, through a separate notification, calendar year 
production allowances to entities that produced a regulated substance 
in 2020. The number of production allowances allocated to each eligible 
entity for 2022-2023 is calculated as follows:
    (1) Take the highest annual exchange value-weighted production 
amount that each eligible entity reported to the agency for calendar 
year 2017, 2018, or 2019, whichever year is highest.
    (2) Sum the ``high year'' values determined in step 1 of all 
eligible entities 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 and the set aside in 
Sec.  84.15 from the production cap in Sec.  84.7(b)(3).
    (4) Determine individual entities' production allowance quantities 
by multiplying each entity's percentage determined in step 2 by the 
amount of general pool allowances determined in step 3.
    (b) (1) EPA will allocate calendar year production allowances to 
individual entities by October 1 of the calendar year prior to the year 
in which the allowances will be used based on the exchange value-
weighted quantities calculated in paragraph (a)(4) of this section.
    (2) EPA will provide public notice of the list of companies 
receiving production allowances as well as the quantities they will be 
allocated by that date.
    (3) In addition to the procedure in paragraph (a) of this section, 
EPA will allocate calendar year production allowances to entities that 
qualified for allowances under Sec.  84.15.
    (4) If there are remaining production allowances after distribution 
from the set aside under Sec.  84.15, EPA will distribute such 
allowances on a pro rata basis to the entities in paragraph (a) of

[[Page 27211]]

this section by March 31 of the calendar year in which the allowances 
will be used.

Sec.  84.11   Allocation of calendar-year consumption allowances.

    (a) EPA will issue, through a separate notification, calendar year 
consumption allowances to entities that imported or produced a bulk 
regulated substance in 2020, unless an individual accommodation is 
permitted by a relevant Agency official. If multiple importers are 
related through shared corporate ownership or control, EPA will 
calculate and issue allowances to a single corporate owner. The number 
of consumption allowances allocated to each eligible entity for 2022-
2023 is calculated as follows:
    (1) Take the highest annual exchange value-weighted bulk 
consumption amount chosen at the corporate-level for eligible entities 
reporting to the agency for each calendar year 2017, 2018, or 2019, 
whichever year is highest.
    (2) Sum the ``high year'' values determined in step 1 of all 
eligible entities and determine each entity's percentage of that total.
    (3) 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 and the set aside in 
Sec.  84.15 from the consumption cap Sec.  84.7(b)(3).
    (4) Determine individual entity consumption allowance quantities by 
multiplying each entity's percentage determined in step 2 by the amount 
of general pool allowances determined in step 3.
    (b)(1) EPA will allocate calendar year consumption allowances to 
individual entities by October 1 of the calendar year prior to the year 
in which the allowances will be used based on the exchange value-
weighted quantities calculated in paragraph (a)(4) of this section.
    (2) EPA will provide public notice of the list of companies 
receiving consumption allowances as well as how they will be allocated 
by that date.
    (c)(1) In addition to the procedure in paragraph (a) of this 
section, EPA will allocate calendar year consumption allowances to 
entities that qualified for allowances under Sec.  84.15.
    (2) If there are remaining consumption allowances after 
distribution from the set aside under Sec.  84.15, EPA will distribute 
such allowances on a pro rata basis to the entities in paragraph (a) of 
this section by March 31 of the calendar year.

Sec.  84.13   Allocation of application-specific allowances.

    (a) Application-specific allowances are available to entities for

the year in which the allowances will be used starting with the 
calendar year 2023 allocation. The application must include the 
following:
    (1) Total quantity (in kilograms) of each specific regulated 
substance acquired and used in the three calendar years prior to the 
year in which the request is being made;
    (2) For regulated substances acquired over the past twelve months 
by conferring allowances to a domestic producer, the quantity (in 
kilograms) acquired, the specific regulated substance acquired, and the 
name and contact information of the supplier.
    (3) For regulated substances acquired over the past twelve months 
by conferring allowances to an importer, the quantity (in kilograms) 
acquired, the specific regulated substance acquired, and the name and 
contact information of the supplier.
    (4) Quantity of each specific regulated substances acquired over 
the past twelve months by expending application-specific allowances for

must meet the criteria for eligibility in this section and are subject 
to the requirements of this section.
    (f) EPA will publish a list of companies allocated application-
specific allowances and their application.
    (g) Application-specific allowances may be expended for either the 
import or production of a regulated substance.
    (h) Conferring application-specific allowances to a producer or 
importer is not subject to the offset required of transfers of 
allowances described in Sec.  84.19.

Sec.  84.15   Set aside of application-specific allowances, production 
allowances, and consumption allowances.

Sec.  84.17   Availability of additional consumption allowances.

    (a) A person may obtain at any time during the year, in accordance 
with the provisions of this section, consumption allowances equivalent 
to the quantity of regulated substances that the person exported from 
the United States and its territories to a foreign country in 
accordance with this section, when that quantity of regulated substance 
was produced in the United States or imported into the United States 
with expended consumption allowances. Both the export of the regulated 
substance and the request for additional consumption allowances must 
occur during the calendar year in which the consumption allowances were 
expended to produce or import those same regulated substances.
    (1) The exporter must submit to the relevant Agency official a 
request for consumption allowances setting forth the following:
    (i) The identities and addresses of the exporter and the recipient 
of the exports;
    (ii) The exporter's Employer Identification Number;
    (iii) The names, telephone numbers, and email addresses of contact 
persons for the exporter and the recipient;
    (iv) The quantity (in kilograms) and name of the regulated 
substances exported;
    (v) The source of the regulated substances and the date purchased;
    (vi) The date on which, and the port from which, the regulated 
substances were exported from the United States or its territories;
    (vii) The country to which the regulated substances were exported;
    (viii) A copy of the bill of lading and the invoice indicating the 
net quantity (in kilograms) of regulated substances shipped and 
documenting the sale of the regulated substances to the purchaser;
    (ix) The commodity codes of the regulated substances exported; and
    (x) A written statement from the producer that the regulated 
substances were produced with expended allowances or a written 
statement from the importer that the regulated substances were imported 
with expended allowances.
    (2) The relevant Agency official will review the information and 
documentation submitted under paragraph (a)(1) of this section and will 
issue a notice to the requestor.
    (i) The relevant Agency official will determine the quantity of 
regulated substances that the documentation verifies was exported and 
issue consumption allowances equivalent to the quantity of regulated 
substances that were exported.
    (A) The grant of the consumption allowances will be effective on 
the date the notice is issued.
    (B) The consumption allowances will be granted to the person the 
exporter indicates, whether it is the producer, the importer, or the 
exporter.
    (ii) The relevant Agency official will issue a notice that the 
consumption allowances are not granted if the official determines that 
the information and documentation do not satisfactorily substantiate 
the exporter's claims.

Sec.  84.19   Transfers of allowances.

    (a) Inter-company transfers. Effective January 1, 2022, a person 
(``transferor'') may transfer to any other person (``transferee'') any 
quantity of the transferor's production allowances, consumption 
allowances, or application-specific allowances for use by the same type 
of application, as long as the following conditions are met:
    (1) An offset equal to five percent of the amount of allowances 
transferred will be deducted from the transferor's production allowance 
balance if a transfer is made of production allowances, or deducted 
from the transferor's consumption allowance balance if a transfer is 
made of consumption allowances. In the case of transferring 
application-specific allowances, one percent of the amount of 
allowances transferred will be deducted from the transferor's 
application-specific allowance balance.
    (2) The transferor must submit to the relevant Agency official a 
transfer claim setting forth the following:
    (i) The identities and addresses of the transferor and the 
transferee;

[[Page 27213]]

    (ii) The names, telephone numbers, and email addresses of contact 
persons for the transferor and the transferee;
    (iii) The type of allowances being transferred, including the 
specific application (if applicable), for which allowances are to be 
transferred;
    (iv) The quantity (in MTEVe) of allowances being transferred;
    (v) The total cost of the allowances transferred;
    (vi) The amount of unexpended allowances of the type and for the 
year being transferred that the transferor holds under authority of 
this subpart as of the date the claim is submitted to EPA;
    (vii) For transfers of consumption allowances or production 
allowances, the quantity of the five percent offset applied to the 
quantity transferred that will be deducted from the transferor's 
allowance balance. For transfers of application-specific allowances, 
the quantity of the one percent offset applied to the quantity 
transferred that will be deducted from the transferor's allowance 
balance.
    (viii) For transfers of application-specific allowances, a signed 
document from the transferee certifying that the transferee will use 
the application-specific allowances only for the same application for 
which the application-specific allowance was allocated.
    (3) The relevant Agency official will determine whether the records 
maintained by EPA indicate that the transferor possesses unexpended 
allowances sufficient to cover the transfer claim as of the date the 
transfer claim is processed. The transfer claim is the quantity in EVe 
to be transferred plus five percent of that quantity or plus one 
percent for application-specific allowances. The relevant Agency 
official will take into account any previous transfers, any production, 
and allowable imports and exports of regulated substances reported by 
the transferor. Within three working days of receiving a complete 
transfer claim, the official will take action to notify the transferor 
and transferee as follows:
    (i) The relevant Agency official will issue a non-objection notice 
to both the transferor and transferee indicating if EPA's records show 
that the transferor has sufficient unexpended allowances to cover the 
transfer claim. In the case of transfers of production allowances or 
consumption allowances, EPA will reduce the transferor's balance of 
unexpended allowances by the quantity to be transferred plus five 
percent of that quantity. In the case of transfers of application-
specific allowances EPA will reduce the transferor's balance of 
unexpended allowances by the quantity to be transferred plus one 
percent of that quantity. The transferor and the transferee may proceed 
with the transfer when EPA issues a non-objection notice. However, if 
EPA ultimately finds that the transferor did not have sufficient 
unexpended allowances to cover the claim, the transferor and 
transferee, where applicable, will be held liable for any violations of 
the regulations of this subpart that occur as a result of, or in 
conjunction with, the improper transfer.
    (ii) The relevant Agency official will issue an objection notice 
disallowing the transfer if EPA's records show that the transferor has 
insufficient unexpended allowances to cover the transfer claim, or that 
the transferor has failed to respond to one or more Agency requests to 
supply information needed to make a determination. Either transferor or 
transferee may file a notice of appeal, with supporting reasons, with 
the relevant Agency official within 10 working days after receipt of 
notification that a transfer was disallowed. The official may affirm or 
vacate the disallowance. If no appeal is filed electronically by the 
tenth working day after notification, the disallowance shall be final 
on that day.
    (4) The transferer and transferee must maintain a copy of the 
transfer claim and a copy of EPA's non-objection or objection notice 
for five years.
    (b) International transfers of production allowances. (1) A person 
may request to increase or decrease their production allowances for a 
specified control period through transfers of such allowances with a 
person in a foreign country if the applicable conditions in this 
paragraph are met. Once transferred, all allowances transferred 
consistent with this paragraph will function as a production allowance, 
as defined in Sec.  84.3.
    (i) Timing of requests. Any request for an increase or decrease in 
production allowances based on an international transfer under this 
paragraph must be submitted by October 1 of the year prior to the 
calendar year in which the transferred allowances would be useable.
    (ii) Timing of the transfer. International transfers under this 
paragraph will be deemed to occur, and the transferred allowances will 
be useable, as of January 1 of the calendar year to which the transfer 
applies.
    (2) Transfer from a person in a foreign country--Information 
requirements. (i) A person requesting to change their production 
allowances based on a transfer from a person in a foreign country must 
submit to the relevant Agency official at the time the international 
transfer is requested a signed document from an official representative 
in that country's embassy in the United States stating that the 
appropriate authority within that country has revised the domestic 
production limits for that country equal to the lowest of the following 
three production quantities:
    (A) The maximum production level permitted in Sec.  84.7(b) in the 
year of the international transfer minus the quantity of production 
allowances (in exchange value-weighted kilograms) to be transferred;
    (B) The maximum production level for the applicable regulated 
substances that are allowed under applicable law (including the foreign 
country's applicable domestic law) minus the quantity of production 
allowances (in exchange value-weighted kilograms) to be transferred; or
    (C) The average of the foreign country's actual national production 
level of the applicable regulated substances for the three calendar 
years prior to the year of the transfer minus the quantity of 
production allowances (in exchange value-weighted kilograms) to be 
transferred.
    (ii) A person requesting a revision based on a transfer from a 
foreign country (``transferee'') must also submit to the relevant 
Agency official a true copy of the document that sets forth the 
following:
    (A) The identity and address of the transferee;
    (B) The foreign country authorizing the transfer;
    (C) The names, telephone numbers, and email addresses of contact 
persons for the transferee and for the person in the foreign country;
    (D) The name of the chemical and quantity (in kilograms) of 
production being transferred;
    (E) Documentation that the foreign country possesses the necessary 
quantity of unexpended production rights;
    (F) The calendar year to which the transfer applies; and
    (G) A signed statement from a responsible official describing 
whether the increased production is intended for export or the market 
in the United States.
    (3) Transfer to a person in a foreign country--Information 
requirements. A person requesting a transfer to a person in a foreign 
country must submit a request to the relevant Agency official that sets 
forth the following information:
    (i) The identity and address of the person seeking to transfer the 
allowances (``transferor'');
    (ii) The foreign country authorizing the transfer;

[[Page 27214]]

    (iii) The names, telephone numbers, and email addresses of contact 
persons for the transferor and for the person in the foreign country;
    (iv) The name of the chemical and quantity (in kilograms) of 
allowable production being transferred; and
    (v) The calendar year to which the transfer applies;
    (vi) A signed statement from a responsible official requesting that 
the relevant Agency official revise the number of production allowances 
the transferor holds such that the aggregate national production in the 
United States is equal the lowest of the following three production 
quantities:
    (A) The maximum production level permitted in Sec.  84.7(b) in the 
year of the international transfer minus the quantity of production 
allowances (in exchange value-weighted kilograms) to be transferred;
    (B) The maximum production for the applicable regulated substances 
that are allowed under applicable law minus the quantity of production 
allowances (in exchange value-weighted kilograms) to be transferred; or
    (C) The average of the United States' actual national production 
level of the applicable regulated substances for the three calendar 
years prior to the year of the transfer minus the quantity of 
production allowances (in exchange value-weighted kilograms) to be 
transferred.
    (4) Review of international transfer request to a foreign country. 
After receiving a transfer request that meets the requirements of 
paragraph (b)(3) of this section, the relevant Agency official may, at 
his/her discretion, consider the following factors in deciding whether 
to approve such a transfer:
    (i) Potential environmental implications; and
    (ii) The total quantity of unexpended production allowances held by 
U.S. entities.
    (5) Notice of transfer. The relevant Agency official will review 
the submitted requests to determine whether the foreign country in 
which the person is located has enacted or otherwise established the 
same or similar requirements or otherwise undertaken commitments 
regarding the production and consumption of regulated substances as are 
contained in the AIM Act, within a reasonable time frame of the date of 
its enactment. If it is determined that these conditions are not met, 
the relevant Agency official will notify the requestor in writing that 
no transfers to or from the country can occur. If these conditions are 
satisfied such that transfers to or from the country can occur, the 
relevant Agency official will consider if the request meets the 
applicable requirements of paragraph (b) of this section. If the 
request meets the requirements of paragraph (b)(2) of this section for 
transfers from foreign countries and paragraph (b)(3) of this section 
for transfers to foreign countries, and if the relevant Agency official 
has not decided to disapprove the request based on consideration of 
factors listed in paragraph (b)(4) of this section if applicable, the 
relevant Agency official will notify the person in writing that the 
appropriate production allowances were either granted or deducted and 
specify the control period to which the transfer applies. Notifications 
of production allowances granted or deducted will be provided before 
January 1 of the calendar year to which the transfer applies.
    (i) For transfers from a foreign country, such notification will 
reflect a revision of the balance of allowances held by the recipient 
of the transfer to equal the unexpended production allowances held by 
the recipient of the transfer plus the quantity of allowable production 
transferred from the foreign country minus an offset of five percent of 
the quantity transferred. The relevant Agency official will not adjust 
available allowances until the foreign country's representative had 
confirmed the appropriate number of allowances were deducted in the 
foreign country.
    (ii) For transfers to a foreign country, such notification will 
reflect a revision of the balance of production allowances for the 
transferor such that the aggregate national production of the regulated 
substance to be transferred is to equal the value the relevant Agency 
official determines to be the lowest of:
    (A) The maximum production level permitted in Sec.  84.7(b) in the 
year of the international transfer minus the quantity of production 
allowances transferred and minus an offset of five percent of the 
quantity transferred; or
    (B) The maximum production level for the applicable regulated 
substances that is allowed under applicable law (in exchange-value 
weighted kilograms) minus the quantity of production allowances 
transferred and minus an offset of five percent of the quantity 
transferred; or
    (C) The average of the actual annual U.S. production of the 
applicable regulated substances for the three years prior to the date 
of the transfer (in exchange-value weighted kilograms minus the 
quantity of production allowances transferred and minus an offset of 
five percent of the quantity transferred.
    (6) Revised production limit for previous transferors. If the 
average actual U.S. production during the three most recent calendar 
years before the date of the transfer is less than the total allowable 
U.S. production for the applicable regulated substances permitted in 
Sec.  84.7(b) for a calendar year for which international transfers are 
approved to occur, the aggregate allowed national U.S. production of 
those substances will be reduced by an additional amount beyond a 
simple deduction of the number of allowances reflected in the 
notifications under paragraph (b)(5)(ii)(B) of this section. In these 
circumstances, the relevant Agency official will revise the production 
limit for each transferor who obtained approval of a transfer of the 
applicable regulated substances to a foreign country in the same 
calendar year and notify each transferor of the revision in writing. 
The amount of the revision will equal the result of the following set 
of calculations:
    (i) The total U.S. allowable production of the applicable regulated 
substances minus the average of the actual annual U.S. production of 
those substances during the three most recent calendar years prior to 
the calendar year of the transfer;
    (ii) The quantity of production allowances for the applicable 
regulated substances transferred by the transferor in that calendar 
year divided by the total quantity of production allowances for those 
substances approved for transfer to a person in a foreign country by 
all the persons approved to make such transfers in that calendar year;
    (iii) The result of paragraph (b)(6)(i) of this section multiplied 
by the result of paragraph (b)(6)(ii) of this section.
    (iv) The unexpended production allowances held by the person minus 
the result of paragraph (b)(6)(iii) of this section.
    (7) Effective date of revised production limits. If a revision is 
issued under paragraph (b)(6) of this section, the change in production 
allowances will be effective on the date that the notification is 
issued.

Sec.  84.21   Sale or transfer of regulated substances produced or 
imported with application-specific allowances.

    (a) Sale or transfer of HFCs produced or imported using 
application-specific allowances. (1) Effective January 1, 2022, any 
person receiving an application-specific allowance (transferor) may 
sell or transfer regulated substances produced or imported using that 
allowance to another person within the same application (transferee) 
provided that

[[Page 27215]]

the relevant Agency official approves the sale or transfer.
    (2) The transferee must submit a claim to the relevant Agency 
official for approval before the sale or transfer can take place. The 
claim must set forth the following:
    (i) The identities and addresses of the transferor and the 
transferee;
    (ii) The name, telephone numbers, and email addresses of contact 
persons for the transferor and the transferee;
    (iii) The amount of each regulated substance being sold or 
transfered;
    (iv) The cost of the regulated substance;
    (v) The specific products that the transferee plans to produce with 
the HFCs; and
    (vi) Certification that the HFCs will be used only for the same 
application for which the application-specific allowance under which 
the substances were produced or imported was allocated.
    (3) The transferor must submit a letter to the relevant Agency 
official stating that it concurs with the terms of the sale or transfer 
as requested by the transferee.
    (4) Once the claim is complete, and if EPA does not object to the 
sale or transfer, then EPA will issue letters to the transferor and the 
transferee within 10 business days indicating that the transaction may 
proceed. EPA reserves the right to disallow a transaction if the claim 
is incomplete, or if it has reason to believe that the transferee plans 
use the regulated substance in anything other than the stated 
application. If EPA objects to the transaction, EPA will issue letters 
to the transferor and transferee stating the basis for disallowing the 
transaction.
    (5) The burden of proof is placed on the transferee to retain 
sufficient records to prove that the sold or transfered regulated 
substances are used only for the stated application.
    (b) [Reserved].

Sec.  84.23   Certification identification generation and tracking.

    (a) Scope and applicability. All containers of bulk regulated 
substance must be associated with a certification identification as of 
January 1, 2024. Certification identifications may only be generated by 
a person that produces, imports, reclaims, repackages, or blends 
regulated substance for distribution or sale in bulk and reports to EPA 
consistent with paragraph (d) of this section.
    (b) Prohibitions. Effective January 1, 2024, every kilogram of bulk 
regulated substance sold or distributed, or offered for sale or 
distribution, in violation of this section is a separate violation of 
this subpart. Every kilogram of bulk regulated substance purchased or 
received, or attempted to be purchased or received in violation of this 
section is a separate violation of this subpart.
    (1) No person may sell or distribute, or offer for sale or 
distribution, and no person may purchase or receive, or attempt to 
purchase or receive, a regulated substance unless the container has a 
valid certification identification.

distribution, regulated substance unless they are registered with EPA 
consistent with Sec.  84.31.
    (3) No person may purchase or receive, or attempt to purchase or 
receive, the regulated substance unless the person is registered with 
EPA consistent with paragraph (d) or a final customer;
    (4) The following situations are exempt from the prohibitions in 
paragraphs (b)(1) through (3) of this section:
    (i) The regulated substance is part of a transhipment and the 
person transhipping the regulated substance has reported to EPA 
consistent with Sec.  84.31(c)(3);
    (ii) The regulated substance was:
    (A) Previously used, has been recovered from a piece of equipment, 
and is intended for reclamation;
    (B) The person selling or distributing the regulated substance 
certifies in writing to the person purchasing or receiving the 
regulated substance was recovered from a piece of equipment and 
provides the date of recovery; and
    (C) The person purchasing or receiving the regulated substance is 
either an EPA-certified refrigerant reclaimer or a registered supplier 
of regulated substances consistent with paragraph (d) of this section.
    (iii) The regulated substance was imported consistent with the 
petition process described in Sec.  84.25 and is being distributed by 
an aggregator or destruction company; or
    (iv) The material was collected for destruction at a destruction 
facility.
    (5) No producer or importer may request certification 
identifications that would exceed their currently available allowances.
    (6) A person who reclaims regulated substances may request 
certification identifications at a level equal to their reported 
reclamation for the prior year plus an amount based on the average 
annual growth in total U.S. HFC reclamation in the prior three years or 
five percent, whichever is higher. If that level is not sufficient, the 
reclaimer must notify EPA 45 days in advance of exceeding their allowed 
level and request approval to generate additional certification 
identifications. The request must estimate the additional certification 
identifications needed for the next six months and provide an 
explanation for the increased level of reclamation. EPA will review the 
request and adjust the amount of certification identifications for the 
person as appropriate within 21 days. Additional requests can be 
submitted throughout the year as needed.
    (7) No regulated substance repackager or blender may request 
certificate identifications unless they have allowances. They may 
generate new QR codes based on the certification identifications 
associated with the containers currently in their possession.
    (c) Required Practices. The following practices are required, 
unless the person purchasing or receiving the bulk regulated substance 
is listed in paragraph (b)(4) of this section:
    (1) Any person producing, importing, reclaiming, packaging, selling 
or distributing, or offering to sell or distribute regulated substances 
must register with EPA consistent with paragraph (d) of this section.
    (2) Any person who introduces a container of regulated substance or 
reclaimed regulated substance into U.S. commerce, must permanently 
affix a QR code to the container that documents a valid certification 
identification using the standards defined by EPA prior to the 
container entering U.S. commerce. For the purposes of this subpart, 
examples of when a container of regulated substance or reclaimed 
regulated substance enters U.S. commerce include arrival at U.S. 
Customs and departure from a production or reclamation facility.
    (3) At the time of sale or distribution, a person selling or 
distributing regulated substance must ensure there is a valid and 
legible certification identification on each container of regulated 
substance, scan the certification identification system to identify a 
transaction, identify the person receiving the regulated substance, and 
indicate whether the person receiving the regulated substance is a 
final customer or supplier.
    (4) At the time of sale or distribution, a person taking ownership 
of a regulated substance that is a registered supplier must ensure 
there is a valid and legible certification identification on each 
container of regulated substance and scan the certification 
identification in the certification identification system to identify a 
transaction.
    (d) Recordkeeping and Reporting--(1) Importers. Any person 
importing a

[[Page 27216]]

container of regulated substance must enter the following information 
in the certification identification system to generate a new QR code 
and associated certification identification for each container of 
regulated substance: The name or brand the regulated substance is being 
sold and/or marketed under, the date it was imported, the unique serial 
number associated with the container, and amount and name of the 
regulated substance(s) in the container.
    (2) Reclaimers. Any person filling a container with a reclaimed 
regulated substance must enter the following information in the 
certification identification system to generate a new QR code and 
associated certification identification for each container of regulated

or marketed under, the date the regulated substance was reclaimed and 
by whom, the date the reclaimed regulated substance was put into a 
container, the unique serial number associated with the container, the 
amount and name of the regulated substance(s) in the container, whether 
the purity of the batch was confirmed to meet the specifications in 
appendix A to 40 CFR part 82, subpart F, the date the batch was tested 
for purity, and who certified the reclaimed regulated substance meets 
the purity specifications. If a container is filled with reclaimed and 
virgin regulated substance(s), the reclaimer must provide the amount of 
virgin regulated substance is included in the container and the 
certification identification(s) associated with that regulated 
substance.
    (3) Producers and Packagers. Anyone who is filling a container, 
whether for the first time after production or when transferring 
regulated substance from one container to one or more smaller or larger 
containers, must enter information in the certification identification 
system and generate a new QR code for the container(s) of repackaged 
regulated substances: The name or brand the regulated substance is 
being sold and/or marketed under, the date it was repackaged, the 
certification identification(s) associated with the regulated substance 
being repackaged, the unique serial number for the container, and 
amount and name of the regulated substance(s) in the container, and the
