Toxic Substances Control Act (TSCA) Section 21 Petition for 
Rulemaking Under TSCA Section 6; Reasons for Agency Response; Denial of 
Requested Rulemaking

AGENCY: Environmental Protection Agency (EPA).

ACTION: Petition; reasons for Agency response.

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

SUMMARY: This action announces the availability of EPA's response to a 
petition received on June 16, 2022, from Daniel M. Galpern on behalf of 
Donn J. Viviani, John Birks, Richard Heede, Lise Van Susteren, James E. 
Hansen, Climate Science, Awareness and Solutions, and Climate 
Protection and Restoration Initiative (the petitioners). The 
petitioners request that EPA in general phase out the anthropogenic 
manufacture, processing, distribution, use, and disposal of greenhouse 
gas (GHG) emissions, fossil fuels, and fossil fuel emissions. They also 
request multiple actions under TSCA, and actions pursuant to the Clean 
Air Act (CAA), the Comprehensive Environmental Response, Compensation, 
and Liability Act (CERCLA), and the Independent Offices Appropriations 
Act (IOAA). EPA has determined that the request for risk management 
rulemaking under TSCA is within the ambit of a petition under TSCA's 
provision for a citizen petition. EPA is treating the other actions 
requested as petitions under the Administrative Procedure Act (APA), 
which this notice does not address. EPA shares the petitioners' 
concerns regarding the threat posed by climate change, and the Biden 
Administration will continue to combat the climate crisis with a whole 
of government approach. Nonetheless, after careful consideration, EPA 
has denied the petition for the reasons set forth in this notice.

DATES: EPA's response to this TSCA section 21 petition was signed 
September 14, 2022.

ADDRESSES: EPA has established a docket for this TSCA section 21 
petition under docket identification (ID) number EPA-HQ-OPPT-2022-0593 
and available online at https://www.regulations.gov. Additional 
instructions on visiting the docket, along with more information about

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    This action is directed to the public in general. This action may, 
however, be of interest to those persons who manufacture (including 
import), process, distribute in commerce, use, or dispose of fossil 
fuels or greenhouse gases. Since other entities may also be interested, 
the Agency has not attempted to describe all the specific entities that 
may be affected by this action.

B. What is EPA's authority for taking this action?

    Under TSCA section 21 (15 U.S.C. 2620), any person can petition EPA 
to initiate a proceeding for the issuance, amendment, or repeal of a 
rule under TSCA sections 4, 6, or 8, or to issue an order under TSCA 
sections 4, 5(e), or 5(f). A TSCA section 21 petition must set forth 
the facts which it is claimed establish that it is necessary to 
initiate the action requested. EPA is required to grant or deny the 
petition within 90 days of its filing. If EPA grants the petition, the 
Agency must promptly commence an appropriate proceeding. If EPA denies 
the petition, the Agency must publish its reasons for the denial in the 
Federal Register. A petitioner may commence a civil action in a U.S. 
district court seeking to compel initiation of the requested proceeding 
within 60 days of a denial or, if EPA does not issue a decision, within 
60 days of the expiration of the 90-day period.

C. What criteria apply to a decision on this TSCA section 21 petition?

1. Legal Standard Regarding TSCA Section 21 Petitions
    TSCA section 21(b)(1) requires that the petition ``set forth the 
facts which it is claimed establish that it is necessary'' to initiate 
the proceeding requested. 15 U.S.C. 2620(b)(1). Thus, in addition to 
petitioners' burden under TSCA section 21 itself, TSCA section 21 
implicitly incorporates the statutory standards that apply to the 
requested actions. Accordingly, EPA has reviewed this TSCA section 21 
petition by considering the standards in TSCA section 21 and in the 
provisions under which actions have been requested.
2. Legal Standard Regarding TSCA Section 6(a).
    Under TSCA section 6(a), if EPA determines that the manufacture, 
processing, distribution in commerce, use, or disposal of a chemical 
substance or mixture, or that any combination of such activities, 
presents an unreasonable risk of injury to health or the environment, 
EPA conducts a rulemaking to apply one or more of TSCA section 6(a) 
requirements to the extent necessary so that the chemical substance or 
mixture no longer presents such risk. In proposing and promulgating 
rules under TSCA section 6(a), EPA considers, among other things, the 
provisions of TSCA sections 6(c)(2), 6(d), 6(g), and 9. In addition, to 
the extent that EPA makes a decision based on science, TSCA section 
26(h) requires EPA, in carrying out TSCA sections 4, 5, and 6, to use 
``scientific information, technical procedures, measures, methods, 
protocols, methodologies, or models, employed in a manner consistent 
with the best available science,'' while also taking into account other 
considerations, including the relevance of information and any 
uncertainties. 15 U.S.C. 2625(h). TSCA section 26(i) requires that 
decisions under TSCA sections 4, 5, and 6 be ``based on the weight of 
scientific evidence.'' 15 U.S.C. 2625(i). TSCA section 26(k) requires 
that EPA consider information that is reasonably available in carrying 
out TSCA sections 4, 5, and 6. 15 U.S.C. 2625(k).

II. Summary of the TSCA Section 21 Petition

A. What action was requested?

    On June 16, 2022, EPA received a TSCA section 21 petition from 
Daniel M. Galpern on behalf of Donn J. Viviani, John Birks, Richard 
Heede, Lise Van Susteren, James E. Hansen, Climate Science, Awareness 
and Solutions, and Climate Protection and Restoration Initiative (Ref. 
1). The petition requests EPA determine that the manufacture, 
processing, distribution in commerce, use, or disposal of greenhouse 
gas emissions, fossil fuels, and fossil fuel emissions present an 
unreasonable risk of injury to health or the environment and initiate a 
proceeding for the issuance of a rule under TSCA section 6(a) to: (1) 
Phase out the manufacture (including import), processing, distribution 
in commerce, use, or disposal of ``subject chemical substances and 
mixtures''; and (2) Remove and sequester, or--in the alternative--
establish a pay-in fund for the purpose of removing, such ``subject 
chemicals substances and mixtures'' from the environment (Ref. 1, pp. 
7-8, 35). The petition seeks action regarding ``subject chemical 
substances and mixtures,'' by which the petition collectively refers to 
``the GHG emissions from all anthropogenic sources, the fossil fuels, 
and those emissions associated with fossil fuels (GHGs and otherwise)'' 
(Ref. 1, p.7). The chemical substances or mixtures implicated by these 
groups, according to the petition, include: ``carbon dioxide 
(CO2), methane (CH4), nitrous oxide 
(N2O) and the Halocarbons--chlorofluorocarbons (CFCs), 
hydrochlorofluorocarbons (HCFCs) and halons (HFCs)) from all sources''; 
``[c]ertain fossil fuels'' that meet the TSCA definition of chemical 
substance or chemical mixture; and both GHGs and ``other pollutants 
released or emitted during'' the manufacture, processing, distribution 
in commerce, use and disposal of fossil fuels, ``including particulate 
matter and sulfur and nitrogen dioxides.'' (Ref. 1, p.7 (footnotes 7-8) 
and p.19).
    The petition requests that EPA also take actions under TSCA 
sections 7 and 9. In addition, the petition requests actions under the 
CAA (CAA sections 108-110, 115), CERCLA (CERCLA sections 101, 102, 104-
108), and the IOAA (31 U.S.C. 9701).
    This Federal Register document specifically addresses the 
petitioners' TSCA section 21 petition requesting EPA to issue rules 
under TSCA section 6(a). This Federal Register document does not 
address the TSCA-requested actions which cannot be addressed under TSCA 
section 21 (i.e., TSCA sections 6(b), 7 and 9), nor does it address the 
petitioners' requests under the CAA, CERCLA, and the IOAA. EPA will 
consider those requests separately, as appropriate, under the APA.
1. Request for Rulemaking Under TSCA Section 6(a)
    The petition requests that EPA undertake rulemaking under TSCA 
section 6(a) to ``phase out [the] production and importation and, as 
warranted, [the] processing, distribution, use or atmospheric disposal 
of subject chemicals substances and mixtures, as required to secure the 
elimination of associated emissions and legacy GHG emissions, on a 
timetable that is consistent with both the overarching need to protect 
and restore a habitable climate system and with the demands of national 
and international security'' and ``remove and securely sequester from 
the environment excess

[[Page 57667]]

atmospheric greenhouse gases including, at minimum, surfeit atmospheric 
carbon dioxide (CO2) and methane (CH4) or, in the 
alternative, to pay into an Atmospheric Carbon Abatement Fund that EPA 
will establish for the purpose of removing such subject chemicals and 
mixtures in an amount and pursuant to a timetable consistent with 
protection and restoration of a habitable climate system'' (Ref. 1, pp. 
7-8). TSCA section 21 provides for the submission of a petition to 
initiate a proceeding for the issuance, amendment, or repeal of a rule 
under TSCA section 4, 6, or 8, or to issue an order under TSCA section 
4, 5(e), or 5(f). As the petitioners are seeking issuance of a rule 
under TSCA section 6(a), this Federal Register document addresses this 
request.
2. Request for Standalone Finding of Unreasonable Risk of Injury to 
Health and the Environment
    The petition requests that EPA ``render a determination that `the 
manufacture, processing, distribution in commerce, use, or disposal' of 
the subject chemical substances and mixtures present an unreasonable 
risk of injury to health or the environment'' (Ref. 1, p. 7). With 
respect to actions under TSCA section 6, TSCA section 21 provides only 
for the submission of a petition seeking the initiation of a proceeding 
for the issuance, amendment, or repeal of a rule under TSCA section 6. 
Citizens may not petition under TSCA section 21 for a stand-alone risk 
determination (i.e., one that is independent from and not solely 
underlying and inherent to a request for a specific rulemaking under 
TSCA section 6(a)) or an Agency risk evaluation pursuant to TSCA 
section 6(b). To the extent that the petition seeks a stand-alone risk 
determination, this Federal Register document does not address this 
specific request because TSCA section 21 does not provide an avenue for 
the petitioners to request a stand-alone risk determination or the 
initiation of the TSCA section 6(b) prioritization (and potential risk 
evaluation) process. However, in reviewing the request for rulemaking 
under TSCA section 6(a) (see Unit II.A.1.), the Agency considered the 
information set forth in the petition that petitioners claim 
establishes that it is necessary to initiate the proceeding requested, 
including the information presented by the petitioners regarding 
whether the manufacture, processing, distribution in commerce, use, or 
disposal of a chemical substance or mixture, or any combination of such 
activities, presents an unreasonable risk of injury to health or the 
environment.
3. Request for Actions Under Other Sections of TSCA, the CAA, CERCLA, 
and the IOAA
    TSCA section 21 does not provide for the submission of a petition 
seeking action under TSCA section 7 or 9, the CAA, CERCLA, or the IOAA. 
Therefore, this Federal Register document does not address those 
portions of the petitioners' filing.
    EPA notes that the petition includes one qualified sentence 
mentioning TSCA section 4: ``If information on the efficacy of removal 
and sequestration technologies is inadequate, the [p]etitioners 
recommend that the Agency utilize its authorities under TSCA [section 
4].'' The sentence is a recommendation related to a potential lack of 
information under a potential sequestration requirement, and the 
petitioners made no attempt to assess the TSCA section 4 standards or 
set forth facts showing a necessity to act under the TSCA section 4 
authorities. For example, in a TSCA section 21 petition seeking the 
issuance of a test rule or order under TSCA section 4(a)(1)(A)(i), the 
burden is on the petitioner to demonstrate that the manufacture, 
distribution in commerce, processing, use, or disposal of a chemical 
substance or mixture, or that any combination of such activities, may 
present an unreasonable risk of injury to health or the environment; 
that information and experience are insufficient to reasonably 
determine or predict the effects of a chemical substance on health or 
the environment; and that testing of the chemical substance is 
necessary to develop the missing information. Moreover, the focus of 
the recommendation in the petition is on how EPA might deal with a 
potential lack of information under a potential sequestration 
requirement under TSCA, but neither point is a live issue. Thus, 
although TSCA section 21 petitions may petition for action under TSCA 
section 4, EPA does not consider the quoted sentence to be a facially 
complete TSCA section 21 petition for action under TSCA section 4 and 
is not addressing it further in this Federal Register document.

B. What support did the petitioners offer?

    To support the request for issuance of a rule under TSCA section 
6(a), the petitioners provided an appendix to the petition that 
contains scientific and economic data and literature on climate change 
(Ref. 1, pp. 38-112 (``Part II: Select Scientific and Economic 
Considerations'')). The appendix is divided into sections that discuss 
Earth's energy imbalance; carbon dioxide, methane, and other 
atmospheric pollutants; risks to land, water, and air biota; risk 
reduction methods, including GHG emission reduction and sequestration; 
and risk reduction costs and benefits.
    The Agency appreciates the robustness of information provided in 
the petition toward showing climate risks and finds it generally 
consistent with decades of peer-reviewed and published data on climate 
change, including risks to human health and the environment. From a 
scientific standpoint, and as described further in Unit III.B.1., EPA 
notes that the information and science provided in the petition is 
generally consistent with what the Agency used to make the 2009 
``Endangerment Finding'' that elevated atmospheric concentrations of 
six key well-mixed GHGs taken in combination may reasonably be 
anticipated to endanger the public health and welfare of current and 
future generations, and does not appear to present information that 
would be considered inappropriate or that the Agency would otherwise 
disagree with related to climate change science.
    EPA also received public comments on the petition, which can be 
viewed via docket ID number EPA-HQ-OPPT-2022-0593, through the Federal 
eRulemaking Portal at https://www.regulations.gov.

III. Disposition of TSCA Section 21 Petition

A. What is EPA's response?

    EPA shares the petitioners' concerns regarding the threat posed by 
climate change, and the Biden Administration will continue to combat 
the climate crisis with a whole of government approach. Nonetheless, 
after careful consideration, EPA has denied this TSCA section 21 
petition. A copy of the Agency's response, which consists of the letter 
to the petitioners and this document, is posted on EPA TSCA petition 
website at https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/tsca-section-21##greenhouse. The response, the petition (Ref. 1), 
and other information is available in the docket for this TSCA section 
21 petition (see ADDRESSES).

B. What was EPA's reason for this response?

    TSCA section 21 provides for the submission of a petition seeking 
the initiation of a proceeding for the issuance, amendment, or repeal 
of a rule

[[Page 57668]]

under TSCA section 6. The petition must set forth the facts which it is 
claimed establish that it is necessary to issue the requested rule. 15 
U.S.C. 2620(b)(1). When determining whether the petition meets that 
burden here, EPA considered whether the petition established that it is 
necessary to issue a TSCA section 6(a) rule to address the manufacture, 
processing, distribution in commerce, use, or disposal of the 
petitioned substances, or any combination of such activities, that the 
petitioners claim present an unreasonable risk of injury to health or 
the environment within the meaning of TSCA section 6(a), 15 U.S.C. 
2605(a). For EPA to be able to conclude within the statutorily-mandated 
90 days of receiving the petition that the initiation of a proceeding 
for the issuance of a TSCA section 6(a) rule is necessary, the petition 
would need to be sufficiently clear and robust.
    EPA evaluated the information presented in the petition and 
considered that information in the context of the applicable 
authorities and requirements of TSCA sections 6, 9, 21, and 26. 
Notwithstanding that the burden is on the petitioners to set forth the 
facts which it is claimed establish that it is necessary for EPA to 
issue the rule sought, EPA nonetheless also considered relevant 
information that was reasonably available to the Agency during the 90-
day petition review period. EPA shares the petitioners' concerns about 
the climate crisis and, as explained in Unit III.B.3.a., the Agency is 
taking numerous actions to combat climate change. As detailed further 
in Units III.B.2 and III.B.3., EPA finds that the petition is 
insufficiently specific and that the petitioners did not meet their 
burden under TSCA section 21(b)(1) of establishing that it is necessary 
to issue a rule under TSCA section 6(a). These deficiencies, among 
other findings, are detailed in this notice.
1. Undeniable Threat Associated With the Climate Crisis.
    The petition addresses a unique challenge--the climate crisis, 
which touches on every facet of commerce and life around the world. EPA 
shares the petitioners' concerns regarding the threat posed by climate 
change, and the Biden Administration has approached the climate crisis 
with a whole of government approach.
    Petitioners argue that risks associated with climate change are 
``unreasonable risks'' under TSCA. The petitioners' reference four past 
instances where EPA made an unreasonable risk determination and 
regulated chemical substances and mixtures under TSCA section 6(a) and 
state that the ``risk of injury to health and the environment (as well 
as actual injury) stemming from fossil fuels and other GHG sources is 
orders of magnitude greater than [such] risks'' (Ref. 1, p. 14). As 
previously mentioned, the petitioners in an appendix to the petition 
discuss risks to land, water, and air biota posed by greenhouse gas 
emissions, fossil fuels, and fossil fuel emissions (Ref. 1). In 
describing this and other information, the petitioners state, ``That 
the subject chemical substances and mixtures present not only an 
unreasonable but also an imminent risk of serious and widespread injury 
has been exhaustively established in credible reports and documents 
available to the Agency, including many adopted by the Agency or by 
other U.S. government units'' (Ref. 1, p. 19).
    The Agency agrees that the climate crisis is an undeniable and 
urgent threat to human health and the environment. Not only is climate 
change happening now, but it is already affecting human health and 
well-being, wildlife, and the natural environment. According to the 
Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment 
Report, ``[i]t is unequivocal that human influence has warmed the 
atmosphere, ocean and land. Widespread and rapid changes in the 
atmosphere, ocean, cryosphere and biosphere have occurred'' (Ref. 2). 
The IPCC states these changes have led to increases in heat waves and 
wildfire weather, reductions in air quality, and more intense 
hurricanes and rainfall events. New records continue to be set for 
indicators such as global average surface temperatures, GHG 
concentrations, and sea level. Billion-dollar weather disasters in the 
United States over the last five years have occurred at more than twice 
the rate of such disasters over the past 42 years, with 2022 already 
seeing multiple large tornadoes, hail storms, floods, heat waves, 
droughts, and wildfire events (Ref. 3). Higher CO2 
concentrations have led to acidification of the surface ocean in recent 
decades, with negative impacts on marine organisms that use calcium 
carbonate to build shells or skeletons. The 4th National Climate 
Assessment (NCA4) found that it is very likely (greater than 90% 
likelihood) that by mid-century, the Arctic Ocean will be almost 
entirely free of sea ice by late summer for the first time in about 2 
million years. Moreover, heavy precipitation events have increased in 
the eastern United States while severe drought and outbreaks of insects 
like the mountain pine beetle have killed hundreds of millions of trees 
in the western United States. Wildfires have burned more than 3.7 
million acres in 14 of the 17 years between 2000 and 2016, and Federal 
wildfire suppression costs were about a billion dollars annually. The 
NCA4 also recognized that climate change can increase risks to national 
security, both through direct impacts on military infrastructure, and 
also by affecting factors such as food and water availability that can 
exacerbate conflict outside U.S. borders. The most severe harms from 
climate change may also fall disproportionately upon underserved 
communities who are least able to prepare for, and recover from, heat 
waves, poor air quality, flooding, and other impacts (Ref. 4). As such, 
understanding and addressing climate change is critical to EPA's 
mission of protecting human health and the environment.
    As set forth in EPA's December 7, 2009, Endangerment Finding under 
section 202(a) of the CAA, the Administrator found, for the purposes of 
that particular provision, that six greenhouse gases taken in 
combination endanger both the public health and the public welfare of 
current and future generations (74 FR 66496, December 15, 2009, FRL-
9091-8). In order to develop this Finding, the Agency held a 60-day 
public comment period on the proposed Finding, during which it received 
over 380,000 public comments. EPA carefully reviewed and considered 
these comments before publishing the final Endangerment and Cause or 
Contribute Findings. Following publication of these Findings, EPA 
received 10 petitions to reconsider the findings, which were denied 
after careful review and consideration. In 2012, the D.C. Circuit in 
Coalition for Responsible Regulation, Inc. v. EPA denied all the 
petitions for review of the 2009 Endangerment and Cause or Contribute 
Findings. 684 F.3d 102 (D.C. Cir. 2012) (per curiam), reh'g denied 2012 
U.S. App. LEXIS 26313, 26315, 25997 (D.C. Cir. 2012). In 2016, EPA 
issued another set of similar findings for greenhouse gas emissions 
from aircraft under section 231(a)(2)(A) of the CAA, triggering a 
requirement for EPA to promulgate standards addressing GHG emissions 
from engines on covered aircraft. For these 2016 Findings, EPA reviewed 
major new peer-reviewed scientific assessments that had been released 
since 2009, finding that ``these new assessments are largely consistent 
with, and in many cases strengthen and add to, the already compelling 
and comprehensive scientific evidence detailing the role of the six 
well-mixed GHGs in driving climate change,

[[Page 57669]]

explained in the 2009 Endangerment Finding'' (81 FR. 54421, August 15, 
2016, FRL-9950-15-OAR). Finally, EPA received four petitions between 
2017 and 2019 for reconsideration, rulemaking, or reopening of the 
Endangerment and Cause or Contribute Findings. EPA denied these 
petitions on April 21, 2022 (87 FR. 25412, FRL-9735-01-OAR), though 
litigation is ongoing. Although EPA does not rely on these findings as 
a basis for today's action, this history highlights a few instances 
where EPA has recognized the significant concerns related to climate 
change. EPA further notes that in describing these prior findings under 
sections 202(a) and 231(a)(2)(A) of the CAA, it is neither reopening 
nor revisiting those findings.
    Thus, the Agency acknowledges both the urgency and uniqueness of 
the threat presented by climate change. However, as explained in the 
following discussion, even assuming EPA were to determine that the 
petitioners have adequately demonstrated that the manufacture, 
processing, distribution in commerce, use, or disposal of at least some 
of ``the subject chemical substances and mixtures'' present an 
unreasonable risk of injury to health or the environment for purposes 
of TSCA section 6(a), EPA nonetheless finds that the petition is 
insufficiently specific and fails to establish that it is necessary to 
issue a rule under TSCA section 6. EPA makes this latter finding in 
light of ongoing and expected federal government actions to address 
these risks, the relative efficiency of TSCA rulemaking, and lack of 
TSCA authority to regulate historical GHG emissions (as described in 
detail in Unit III.B.3.).
2. Insufficient Specificity of the Petition
    As an initial matter, the petitioners' request for a rule is 
insufficient because it lacks specificity, especially in comparison to 
the magnitude of the request. In light of the sprawling nature of the 
climate problem and its solutions, and the number of federal government 
activities already ongoing to address the problem (discussed further in 
Unit III.B.3.a), the petitioners must do more to specify what the 
petitioners are seeking for EPA to do under TSCA with respect to 
particular chemical substances or mixtures (e.g., by specifying each 
chemical substance on the TSCA Inventory implicated by the broad 
request to regulate, among others, fossil fuels, fossil fuel emissions, 
and halocarbons as groups) and the activities associated with each 
chemical substance (including each source of GHG emissions) that the 
petitioners seek a TSCA rule to address. In other words, while EPA 
undeniably has authority under TSCA to regulate chemical substances and 
mixtures (see TSCA sections 3(2), 3(10), 6(a)), including those that 
may be implicated by the petition, the petitioners must provide more 
specificity on which chemical substances and which mixtures from which 
sources and activities the petitioners ask EPA to regulate under TSCA 
and, to the extent petitioners implicitly seek categorization under 
TSCA section 26(c), more specificity on the extent of such 
categorization and the basis to treat any such category as a single 
chemical substance or a single mixture.
    The petitioners assert in their petition that ``it is not 
Petitioners' burden here to propose in detail requirements that EPA 
should propose following its determination'' (Ref. 1 p. 15). But 
especially under the unique circumstances presented in this case, where 
the petitioners identify a wide-ranging global threat associated with 
innumerable activities and a multitude of chemical substances and 
mixtures (many of whose emissions are already subject to regulation 
under other federal authorities or are anticipated to be affected by 
resources provided under the Inflation Reduction Act of 2022 (IRA), 
Public Law 117-169 (2022) (see discussion in Unit III.B.3.)), the 
petitioners did not sufficiently clarify the contours of the ``rule'' 
under TSCA they assert it is necessary for the Agency to issue. 
Petitioners' request potentially affects an extraordinary number of 
industries and activities (e.g., agriculture, transportation, 
utilities, etc.), including innumerable small sources of emissions 
(e.g., residential homes). In the context of the massive climate change 
problem, the petitioners did not provide a sufficiently specific and 
targeted request addressing particular substances and industries, so 
that EPA can determine within 90 days whether the petition sets forth 
the facts which it is claimed establish that it is necessary to issue a 
TSCA section 6(a) rule, and whether any part of the requested rule (in 
addition to the requested requirement for removal and sequestration of 
legacy GHG emissions, which as discussed in Unit III.B.3.c is not 
authorized under TSCA section 6(a)) falls beyond the outer bounds of 
EPA's regulatory authority under TSCA section 6(a).
    The petitioners attempted to group together very different types of 
substances under one defined term that the petition labeled as 
``subject chemical substances and mixtures.'' The petitioners described 
these broad groups as ``the GHG emissions from all anthropogenic 
sources, the fossil fuels, and those emissions associated with fossil 
fuels (GHGs and otherwise)'' (Ref. 1 p. 7). Yet even within each of 
these three broad groups, there is a multitude of chemical substances 
that might fit. Apart from giving examples of some of the substances 
that the petition envisioned being addressed by EPA regulation (Ref. 1 
p. 7 footnotes 7-8, and p. 19), the petition did not specify the extent 
of the chemical substances or mixtures for which rulemaking action was 
sought and did not explain the basis or boundary for any 
categorization.
    Moreover, although the petition sought a rule for the ``subject 
chemical substances and mixtures,'' EPA believes that a rule for GHGs, 
for example, would look very different than a rule for fossil fuels, 
for example, in light of differences in TSCA section 6(a) regulatory 
tools for manufacture, processing, distribution in commerce, use, or 
disposal and differences in appropriate regulatory approaches for the 
relevant chemical substance. For example, the TSCA section 6(a) 
regulatory options for disposal significantly differ from those tools 
for manufacturing, processing, or distribution. Even within the group 
of GHGs, a rule addressing carbon dioxide would likely look very 
different from a rule addressing methane, or nitrous oxide, or any one 
of various halocarbons, due to the differences in the activities that 
result in atmospheric releases of these substances. The petition's 
imprecision about what type of regulation it sought for which chemical 
substance or mixture under which of its activities is a significant 
deficiency, especially considering the wide range of substances and 
activities the petition implicates, as well as the aggressive action 
already taken or underway across a wide range of statutes for many of 
these same activities (such as EPA's ongoing actions to implement the 
mandated reductions in HFC production and consumption within the 
American Innovation and Manufacturing (AIM) Act, for example).
3. Necessity of Regulation Under TSCA
    More broadly, and relatedly, even assuming the petition were 
sufficiently specific, and that EPA were to determine that an 
unreasonable risk is presented for purposes of TSCA section 6(a), the 
petitioners have failed to demonstrate that regulation under TSCA is 
``necessary'' under the unique circumstances presented here. TSCA 
section 21 requires petitioners to set forth the facts which it is 
claimed establish that it is necessary to issue, amend, or repeal a 
rule under TSCA section 6. In addition to the scientific

[[Page 57670]]

information provided in the appendix to the petition, the petitioners 
argue that a TSCA section 6(a) rule is necessary because of 
insufficient domestic action to date, lack of regulation of legacy 
emissions, and the specific applicability of TSCA to achieve ``deep 
decarbonization'' (Ref. 1, pp. 22-24).
    As discussed in Unit III.B.3.a., the federal government has 
numerous programs aimed at reducing GHG emissions, and President Biden 
has committed to a whole of government approach to using federal tools 
to reduce GHG emissions. Notably, since the petitioners filed their 
petition, Congress passed the most significant climate legislation 
ever, the IRA. The IRA marks the largest investment in history to 
combat climate change ($369 billion) and will focus in part on reducing 
harmful pollution, building a clean energy economy, and lowering energy 
costs. Moreover, the IRA ensures efforts to tackle the climate crisis 
and secure environmental and economic benefits for all people, that 
investments will reach the communities that need them most, and that 
EPA will accelerate work on environmental justice and empower 
community-driven solutions in overburdened neighborhoods (Ref. 5). The 
petitioners have not demonstrated that all of the existing and 
anticipated federal programs, including but not limited to those 
discussed in this notice (as well as efforts by state, local, and 
tribal governments and private entities), will fail to achieve 
sufficient progress towards meeting U.S. GHG reduction targets or that, 
in particular, a TSCA section 6(a) rule requiring the phase-out of 
manufacturing, processing, distribution in commerce, use, or disposal 
of the ``subject chemical substances and mixtures,'' is necessary to 
make sufficient progress towards meeting these targets to address the 
threat posed by climate change in light of actions under all of the 
other federal programs. As a result, EPA need not here opine on the 
outer extent of the Agency's authority under TSCA to phase out 
greenhouse gases or fossil fuels.
    Further, as described in this Unit III.B.3.b., EPA retains 
discretion in TSCA section 6(a) rulemaking to refer action to other 
agencies and EPA programs under TSCA section 9 and to grant exemptions 
from TSCA section 6(a) rule requirements under TSCA section 6(g) as 
appropriate (such as where compliance with a requirement, as applied 
with respect to a specific condition of use, would significantly 
disrupt the national economy, national security, or critical 
infrastructure), and EPA is required to consider reasonably 
ascertainable economic consequences of the rule, as well as 
availability of technically and economically feasible safer 
alternatives, among other requirements. The exercise of these 
authorities could lead to rulemaking that would not achieve emission 
reductions more expeditiously or efficiently than those achieved 
through other nationwide efforts.
    Finally, as described in Unit III.B.3.c., EPA lacks authority under 
TSCA section 6(a) to require removal and sequestration (or pay-in fund 
for removal) of historical GHG emissions as requested by the petition.
a. Substantial Ongoing and Expected Federal Government Actions
    The petitioners assert that efforts to restrict fossil fuel and 
other GHG emissions ``pursuant to other statutes'' lack a ``fossil fuel 
phaseout course'' and have not put the United States on track to 
achieve national GHG emission reduction targets for 2030, 2035, and 
2050; and that ``[n]o federal statute, other than TSCA, provides the 
Agency with the needed comprehensive authority and duty to impose 
requirements prohibiting or restricting the manufacture, processing, 
distribution, use or disposal'' of GHG emissions, fossil fuels, and 
fossil fuel emissions (Ref. 1, pp. 22-24). As such, the petitioners 
conclude that a TSCA section 6(a) rule is necessary ``because the 
Agency has declined to date to undertake the requested or equivalent 
actions on its own'' and that such a rule is the only means to address 
GHG emissions, fossil fuels, and fossil fuel emissions ``until the 
point that their unreasonable risk is abated'' (Ref. 1, p. 22-24).
    In fact, the U.S. Government has made and will continue to make 
substantial efforts to reduce future domestic emissions. In 2021, in 
line with Article 4 of the Paris Agreement, the U.S. Nationally 
Determined Contribution set a GHG reduction target of 50-52% below 2005 
levels by 2030, and net zero emissions by no later than 2050 (Ref. 6 
and 7). Meeting these ambitious targets will be achieved through 
benefits from actions already implemented, as well as future 
anticipated mitigation efforts. The recently-enacted IRA is expected to 
help reduce GHG emissions to 40% below 2005 levels by 2030, and ``get 
the U.S. a significant way towards our overall 2030 climate goals, 
positioning the [United States] to reach 50-52% GHG emission reductions 
below 2005 levels in 2030 with continued executive branch, state, 
local, and private sector actions.'' (Ref. 8). The IRA will help reduce 
emissions in both the near and long term by creating credits for clean 
electricity, energy storage, nuclear energy, and electric vehicles. 
Additionally, it supports agricultural conservation efforts, clean 
manufacturing, and more efficient buildings. A fee on methane emissions 
will also create incentives for the oil and gas industry to reduce 
leakage and waste. The IRA follows on the heels of the Bipartisan 
Infrastructure Law of 2021 (Infrastructure Investment and Jobs Act), 
Public Law 117-58, 135 Stat. 429 (2021), which advances a variety of 
infrastructure investments that will reduce transportation-related GHG 
emissions, including investing billions of dollars to modernize and 
expand sustainable public transit infrastructure, build out the first-
ever national network of electric vehicle chargers in the United 
States, and deliver thousands of electric school buses nationwide, 
among other things, as well as investing in clean energy transmission 
and the electric grid (Ref. 9 and 10).
    The IRA and Bipartisan Infrastructure Law will lead to new GHG 
emissions reductions on top of already existing government programs, 
such as the implementation of the AIM Act of 2020 (see e.g., 86 FR 
55116, October 5, 2021 (FRL 8458-02-OAR)) which includes measures to 
reduce HFC production and consumption by 85% over the next 15 years; a 
series of rules addressing GHG emissions from light duty and heavy duty 
vehicles (86 FR 74434, December 31, 2021 (FRL-8469-01-OAR); 85 FR 
24174, April 30, 2020 (FRL-10000-45-OAR); 81 FR 73478, October 25, 2016 
(FRL-9950-25-OAR); 77 FR 62624 October 15, 2012 (FRL-9706-5); 76 FR 
57106, September 15, 2011 (FRL-9455-1); 75 FR 25324, May 7, 2010 (FRL-
9134-6)), GHG standards for aircraft (86 FR 2136, January 11, 2021 
(FRL-10018-45-OAR)), standards for new and existing municipal solid 
waste landfills to reduce methane emissions (86 FR 27756, May 21, 2021 
(FRL-10022-82-OAR); 81 FR 59275, August 29, 2016 (FRL-9949-55-OAR), 81 
FR 59331, August 29, 2016 (FRL-9949-51-OAR)), New Source Performance 
Standards for new, modified, and reconstructed fossil fuel-fired power 
plants (80 FR 64510, October 23, 2015 (FRL-9930-66-OAR)), standards to 
reduce methane emissions from the oil and natural gas industry (81 FR 
35824, June 3, 2016 (FRL-9944-75-OAR); 85 FR 57398, November 15, 2020 
(FRL-10013-60-OAR)), and limitations on GHG emissions from new and 
modified stationary sources in construction permits under the PSD 
program, based on the requirement to apply Best Available Control

Technology (BACT) (42 U.S.C. 7475(a)(4); Utility Air Regulatory Group 
(UARG) v. EPA, 134 S.Ct. 2427, 2447-49 (2014); 80 FR 50199, 50200, 
August 19, 2015 (FRL-9932-11-OAR)). Moreover, in 1990, Congress amended 
the CAA to include Title VI (42 U.S.C. 7671c-7671q), which includes 
measures that are directed at phasing out production and consumption of 
listed class I substances, which include CFCs, halons, and carbon 
tetrachloride, and listed class II substances, which are HCFCs. To 
implement the phaseout of class I substances, EPA issued a rule in 1992 
to limit the production and consumption of class I substances, with 
production and consumption of most such substances to be phased out by 
January 1, 2000, and then in 1993 EPA announced the acceleration of the 
phaseout date for the production of most class I substances from 
January 1, 2000 to December 31, 1995 (57 FR 33754, July 30, 1992 (FRL-
4158-2) and 58 FR 65018, December 10, 1993 (FRL-4810-7)). In 1993, EPA 
established a phaseout schedule for HCFCs, which focused on certain 
HCFCs first and will lead to a complete phaseout of the production and 
consumption of HCFCs by 2030 (see e.g., 58 FR 65018, December 10, 1993 
(FRL-4810-7) and 85 FR 15258, March 17, 2020 (FRL-10003-80-OAR)).
    Beyond the IRA and the highlighted regulatory programs, EPA's 
efforts also include coordinating international programs such as the 
Global Methane Initiative (see https://www.globalmethane.org/), 
domestic labeling and voluntary programs such as ENERGY STAR (see 
https://www.energystar.gov/), Natural Gas Star (see https://www.epa.gov/natural-gas-star-program), the Coalbed Methane Outreach 
Program (see https://www.epa.gov/cmop), and the Landfill Methane 
Outreach Program (see https://www.epa.gov/lmop), developing Agency, 
Regional, and program-office climate adaptation plans, and 
communication and educational efforts such as the updated Climate 
Change web page (see https://www.epa.gov/climate-change). EPA also 
partners with states and tribes to assist with adaptation and 
mitigation through programs such as Creating Resilient Water Utilities 
(see https://www.epa.gov/crwu) and the State and Local Climate and 
Energy Program (see https://www.epa.gov/statelocalenergy/local-climate-and-energy-program).
    EPA also is developing new stationary and mobile source standards 
under the CAA to better control GHG emissions from oil and gas 
operations, electric generating units (EGUs), and vehicles. Examples 
include the following:
     Oil and gas methane new source performance standards (RIN 
2060-AV16);
     Oil and gas methane emission guidelines (RIN 2060-AV16);
     EGU GHG new source performance standards (RIN 2060-AV09);
     EGU GHG emission guidelines (RIN 2060-AV10);
     Phase 3 GHG standards for heavy-duty engines and vehicles 
(RIN 2060-AV50); and
     Multi-pollutant emissions standards for model years 2027 
and beyond, light duty and medium duty vehicles (RIN 2060-AV49).
    These rules under development will build on earlier stationary and 
mobile source standards. Similarly, EPA is continuing its work to 
address HFCs through timely and effective implementation of the AIM 
Act. Those efforts include development of a rule (RIN 2060-AV45) to 
provide the framework for how the Agency will issue allowances in 2024 
and later years for the phasedown of the production and consumption of 
listed HFCs on the schedule listed in the AIM Act, and a rule (RIN 
2060-AV46) under subsection (i) of the AIM Act, which provides EPA 
authority to restrict, fully, partially, or on a graduated schedule, 
the use of HFCs in sectors or subsectors in which they are used. The 
public may track the regulatory plan for these and other actions by 
searching or browsing the Unified Agenda of Regulatory and Deregulatory 
Actions, available online at https://www.reginfo.gov/public/do/eAgendaMain.
    In addition, in combination with state, local, tribal, and 
international actions, the U.S. federal government is pursuing a whole 
of government strategy to reduce GHG emissions to protect current and 
future generations. For example, federal initiatives launched since 
2021 from the U.S. Department of Agriculture, the U.S. Department of 
Energy, the U.S. Department of the Interior, and the U.S. Department of 
Transportation, include investments to build or improve renewable 
energy infrastructure in rural communities (Ref. 11); partnerships to 
finance pilot projects that create market opportunities for U.S. 
agricultural and forestry products that use climate-smart practices 
(Ref. 12); efforts to accelerate innovation in carbon dioxide removal 
and storage (Ref. 13), initiatives to catalyze nationwide development 
of new and upgraded high-capacity electric transmission lines (Ref. 
14); approvals for construction and operation of commercial-scale, 
offshore wind energy projects (Ref. 15); programs to allow states, 
tribes, and territories to retrofit low-income homes to increase energy 
efficiency and lower utility bills (Ref. 16); and grants to transit 
agencies, territories, and states for bus fleets that use zero-
emissions technology and training for transit workers to maintain and 
operate new clean bus technology (Ref. 17). In addition, the U.S. 
Securities and Exchange Commission proposed rule changes in Spring 2022 
that, if finalized, would require registrants to provide certain 
climate-related information in their registration statements and 
periodic reports, including certain information about climate-related 
financial risks and disclosure of a registrant's GHG emissions, to 
enable investors to make informed judgments about the impact of 
climate-related risks on current and potential investments (87 FR 
21334, April 11, 2022). At the state level, the U.S. Climate Alliance--
including 24 states and 2 U.S. territories--continue to work to combat 
climate change through policies that encourage investment in clean 
energy, energy efficiency, and climate resilience. Following the 
passage of the IRA, this organization published tools and resources to 
help states better utilize the social cost of greenhouse gases (Ref. 
18).
    In light of actions taken to date, as well as ongoing and planned 
actions, and with the recently authorized resources and programs under 
the IRA, the Agency finds that the petitioners have not met the TSCA 
section 21(b)(1) burden to establish that it is necessary to initiate a 
proceeding under TSCA section 6(a) at this time. EPA believes that 
actions under all of these other authorities and programs are best 
suited at this time to address the urgent threat of climate change.
b. Relative Efficiency of TSCA Rulemaking
    Even if EPA were to initiate a rulemaking proceeding under TSCA 
section 6(a) to address an unreasonable risk associated with 
prospective GHG emissions and/or fossil fuels, any final rule under 
TSCA would be unlikely to achieve emissions reductions more 
expeditiously or efficiently than those that are already anticipated to 
be achieved through the IRA and other recent, ongoing, or planned 
federal actions.
    In proposing and promulgating rules under TSCA section 6(a), EPA 
considers the provisions of TSCA sections 6(c)(2), 6(d), 6(g), and 9. 
TSCA section 6(c)(2)(A) requires EPA to consider and publish a 
statement based on reasonably available information with respect to:

[[Page 57672]]

the effects of the chemical substance or mixture on health and the 
environment and magnitude of exposure; the benefits of the chemical 
substance or mixture for various uses; and reasonably ascertainable 
economic consequences of the rule (15 U.S.C. 2605(c)(2)(A)). These 
economic consequences include consideration of the likely effect of the 
rule on the national economy, small business, technological innovation, 
the environment, and public health; the costs and benefits of the 
proposed and final regulatory action and of one or more primary 
alternative regulatory actions considered by the Administrator; and the 
cost effectiveness of the proposed regulatory action and of the one or 
more primary alternative regulatory actions considered by the 
Administrator (15 U.S.C. 2605(c)(2)(A)(iv)). EPA must factor in these 
considerations to the extent practicable when selecting among 
prohibitions and other restrictions in the rulemaking (15 U.S.C. 
2605(c)(2)(B)).
    In addition, under TSCA section 6(d), any rule under TSCA section 
6(a) must provide for a reasonable transition period (15 U.S.C. 
2605(d)(1)(E)). Further, in deciding whether to prohibit or restrict in 
a manner that substantially prevents a specific condition of use of a 
chemical substance or mixture, and in setting an appropriate transition 
period for such action, EPA must also consider, to the extent 
practicable, whether technically and economically feasible alternatives 
that benefit health or the environment, compared to the use so proposed 
to be prohibited or restricted, will be reasonably available as a 
substitute when the proposed prohibition or other restriction takes 
effect (15 U.S.C. 2605(c)(2)(C)).
    TSCA section 6(g) allows EPA to grant an exemption from a 
requirement of a TSCA section 6(a) rule for a specific condition of use 
of a chemical substance or mixture, if the Administrator finds that: 
the specific condition of use is a critical or essential use for which 
no technically and economically feasible safer alternative is 
available; compliance with the requirement, as applied with respect to 
the specific condition of use, would significantly disrupt the national 
economy, national security, or critical infrastructure; or the specific 
condition of use of the chemical substance or mixture, as compared to 
reasonably available alternatives, provides a substantial benefit to 
health, the environment, or public safety (15 U.S.C. 2605(g)(1)). EPA 
must establish a time limit on any exemption, to be determined by the 
Administrator as reasonable on a case-by-case basis, but may extend an 
exemption where warranted (15 U.S.C. 2605(g)(3)).
    Taken together, the TSCA sections 6(c)(2), (d), and (g) 
considerations regarding economic consequences, reasonable transition 
periods, technically and economically feasible alternatives, and 
critical exemptions indicate that a rulemaking proceeding under TSCA 
section 6(a) at this time would be unlikely to reduce GHG emissions 
more expeditiously or efficiently than would actions under the IRA, the 
Bipartisan Infrastructure Law, the CAA and other environmental 
statutes, and the AIM Act, as well as the other federal government 
actions described earlier. The historic and transformational climate 
investments made in the IRA and the Bipartisan Infrastructure Law, and 
the ongoing regulatory actions under the CAA and other statutes, 
provide a means for reducing GHG emissions more rapidly and efficiently 
than would initiating a new rulemaking proceeding under TSCA.
    Furthermore, TSCA section 9(b) provides that EPA ``shall coordinate 
actions taken under [TSCA] with actions taken under other Federal laws 
administered in whole or in part by [EPA]'' (15 U.S.C. 2608(b)(1)). 
TSCA section 9(d) further instructs the Administrator to consult and 
coordinate TSCA activities with other federal agencies for the purpose 
of achieving the maximum enforcement of TSCA while imposing the least 
burden of duplicative requirements. TSCA sections 9(a) and (b) each 
establish mechanisms for referring an unreasonable risk identified 
under TSCA for risk management action under another federal statute if 
the Administrator determines that the risk could be eliminated or 
reduced to a sufficient extent by action taken under that other federal 
statute. Through TSCA section 9, Congress intended ``to assure that 
overlapping or duplicative regulation is avoided'' (S. Rep. No. 94-
1302, at 84 (1976) (Conf. Rep.)). Given the range of other federal 
actions either planned or already underway to address risks posed by 
various GHGs and emissions associated with fossil fuels--including but 
not limited to those described previously in this notice--other federal 
authorities clearly play a crucial role in addressing risks from GHG 
emissions and climate change. Accordingly, even if EPA were to initiate 
a rulemaking proceeding under TSCA section 6(a), the Agency would 
retain discretion to refer action under TSCA section 9, and would 
necessarily consider whether the risks could be better addressed under 
other federal authorities such as the CAA.
    Although not a basis for EPA's denial, the Agency notes that the 
TSCA program is still relatively nascent following comprehensive 
amendments to the law in 2016, which significantly expanded the 
Agency's requirements and responsibilities. In the years that followed 
the amendments, and despite the substantially increased workload, the 
program's budget remained essentially flat (Ref 19). As a result, 
although the program has made continued progress, it continues to 
struggle to meet statutory deadlines to, for example, review pre-
manufacture notices for new chemicals, conduct risk evaluations, and 
regulate chemicals that the Agency has determined to present 
unreasonable risks, risks that in many cases only TSCA has the clear 
federal authority to address.
    Because there are numerous other federal, state and local actions 
already undertaken or underway to address the climate crisis, and 
because EPA believes that a complete consideration of the costs, 
critical and military uses, needed transition times, technological 
feasibility, and other required factors and discretionary 
considerations under TSCA would be unlikely to lead to a different 
outcome than these other actions for the activities involving the GHG 
emissions, fossil fuels, and/or fossil fuel emissions that would be 
subject to a TSCA rule, EPA believes it is unnecessary and would be an 
inefficient use of government resources to initiate a new, resource-
intensive rulemaking under TSCA at this time.
c. TSCA Authority To Address Legacy Emissions
    In regard to legacy emissions, the petitioners argue that EPA ``has 
not yet imposed any requirement pursuant to any statute upon any fossil 
fuel company, or indeed, upon any other source of GHG emissions, to 
remove all, or even a share, of such source's legacy GHG emissions'' 
and that TSCA is the only federal statute that can compel a party to 
``remove and securely sequester their legacy GHG emissions'' (Ref. 1, 
p. 23). The petitioners advocate for the removal of such legacy 
emissions because the ``scientific consensus is that humanity has 
already far overshot the safe level of atmospheric CO2 and 
other GHGs so that, even in conjunction with a rapid yet feasible 
phaseout of additional quantities of the subject chemical substances 
and mixtures, at least some substantial carbon removal will be 
necessary to protect and restore a viable climate system'' (Ref. 1, p. 
23). To achieve the outcome of removing

[[Page 57673]]

and sequestering historical GHG emissions from the atmosphere or 
undertaking a security and burden sharing agreement (i.e., carbon 
abatement fund) based on such historical GHG emissions, the petitioners 
invoke TSCA section 6(a)(6) and 6(a)(7).
    EPA does not have legal authority under TSCA to require removal and 
sequestration of historical GHG emissions from the atmosphere, or to 
establish an atmospheric GHG abatement fund and require historical GHG 
emitters to pay into the fund based on such historical GHG emissions. 
EPA considers such historical GHG emissions to be legacy disposals 
(i.e., disposals that have already occurred), and EPA has interpreted 
legacy disposals to be excluded from those ``conditions of use'' that 
EPA evaluates and regulates under TSCA. See Safer Chemicals v. EPA, 943 
F.3d 397, 425-26 (9\th\ Cir. 2019) (upholding EPA's exclusion of legacy 
disposals from consideration as conditions of use under the TSCA Risk 
Evaluation rule); 15 U.S.C. 2602(4). Thus, EPA does not consider 
historical GHG emissions to be activities subject to regulation under 
TSCA section 6(a). EPA recognizes that TSCA section 6(a)(6) could be 
used to address ongoing or prospective disposal by certain entities and 
that TSCA section 6(a)(7) could be used to require manufacturers or 
processors to replace or repurchase their substances. However, the 
petitioners have not demonstrated how either of these tools could--
either legally or practically--be used to impose regulatory 
requirements on entities today based on activities that occurred 
decades ago.

C. What were EPA's conclusions?

    The petitioners' request to initiate a proceeding for the issuance 
of a rule under TSCA section 6(a) lacks sufficient specificity, 
especially in comparison to the magnitude of the request. Even assuming 
that the petition were sufficiently specific in its request for a rule, 
when the requested actions are considered in the context of the IRA and 
current actions under the CAA, the Bipartisan Infrastructure Law, the 
AIM Act, and other statutes, which include programs being implemented 
by a range of federal agencies, as well as considerations inherent to 
the promulgation of a TSCA section 6(a) rule, EPA's review of relevant 
information that was reasonably available to the Agency during the 90-
day petition review period does not support a grant of the petition to 
initiate rulemaking under TSCA section 6(a). The petitioners have not 
established at this time that it is ``necessary'' to initiate a 
proceeding for the issuance of a TSCA rule, given the unique challenges 
of the climate crisis, the multitude of other ongoing federal efforts 
to address it, and the other considerations discussed in this notice. 
The Agency does not believe that a rulemaking proceeding under TSCA at 
this time would likely achieve a different result than aforementioned 
federal authorities and programs in addressing climate change, 
greenhouse gas emissions, fossil fuels, and fossil fuel emissions. 
Accordingly, EPA denied the request to initiate a proceeding for the 
issuance of a rule under TSCA section 6(a).
