Air Quality: Revision to Definition of Volatile Organic 
Compounds--Exclusion of trans 1-chloro-3,3,3-trifluoroprop-1-ene 
[SolsticeTM 1233zd(E)]

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The EPA is taking final action to revise the regulatory 
definition of volatile organic compounds (VOCs) for purposes of 
preparing state implementation plans (SIPs) to attain the national 
ambient air quality standards (NAAQS) for ozone under title I of the 
Clean Air Act (CAA). This final action adds trans 1-chloro-3,3,3-
trifluoroprop-1-ene (also known as SolsticeTM 1233zd(E)) to 
the list of compounds excluded from the regulatory definition of VOCs 
on the basis that this compound makes a negligible contribution to 
tropospheric ozone formation. As a result, if you are subject to 
certain federal regulations limiting emissions of VOCs, your emissions 
of SolsticeTM 1233zd(E) may not be regulated for some 
purposes. This action may also affect whether SolsticeTM 
1233zd(E) is considered as a VOC for state regulatory purposes, 
depending on whether the state relies on the EPA's regulatory 
definition of VOCs. An exemption for SolsticeTM 1233zd(E) 
was promulgated first as a direct final rulemaking but was withdrawn 
because EPA received an adverse comment.

DATES: This rule is effective on September 27, 2013.

I. General Information

A. Does this action apply to me?

    Entities potentially affected by this final rule include, but are 
not necessarily limited to, state and local air pollution control 
agencies that adopt and implement regulations to control air emissions 
of VOCs; industries involved in the manufacture or use of refrigerants, 
aerosol and non-aerosol solvents and blowing agents for insulating 
foams; and manufacturers of refrigeration equipment, hot water heaters 
and waste heat recovery equipment. If you have questions regarding the 
applicability of this action to a particular entity, consult the person 
listed in the preceding FOR FURTHER INFORMATION CONTACT section. This 
action has no substantial direct effects on industry because it does 
not impose any new mandates on these entities, but, to the contrary, 
removes SolsticeTM 1233zd(E) from the regulatory definition 
of VOCs. The use of this compound remains subject to other restrictions 
under the CAA. Specifically, the use of this compound as an aerosol 
propellant, blowing agent or refrigerant, or any other use in which it 
would substitute for chlorofluorocarbons, hydrochlorofluorocarbons or 
their substitutes, is subject to restrictions under the Significant New 
Alternatives Policy (SNAP) program (CAA Sec.  612; 40 CFR part 82 
subpart G). The SNAP program has issued final approvals for 
SolsticeTM 1233zd(E) as a suitable foam and refrigerant 
substitute and as a propellant (74 FR 50129, September 30, 2009; 75 FR 
34017, June 16, 2010), and as a solvent for metals, electronics, and 
precision cleaning and in adhesives, coatings, and inks.

II. Background

A. The EPA's VOC Exemption Policy

    Tropospheric ozone, commonly known as smog, is formed when VOCs and 
nitrogen oxides (NOX) react in the atmosphere in the 
presence of sunlight. Because of the harmful health effects of ozone, 
the EPA and state governments limit the amount of VOCs that can be 
released into the atmosphere. VOCs are those organic compounds of 
carbon that form ozone through atmospheric photochemical reactions. 
Different VOCs have different levels of reactivity. That is, they do 
not react to form ozone at the same speed or do not form ozone to the 
same extent. Some VOCs react slowly or form less ozone; therefore, 
changes in their emissions have less and, in some cases, very limited 
effects on local or regional ozone pollution episodes. It has been the 
EPA's policy that organic compounds with a negligible level of 
reactivity should be excluded from the regulatory definition of VOCs so 
as to focus VOC control efforts on compounds that do significantly 
increase ozone concentrations. The EPA also believes that exempting 
such compounds creates an incentive for industry to use negligibly 
reactive compounds in place of more highly reactive compounds that are 
regulated as VOCs. The EPA lists compounds that it has determined to be 
negligibly reactive in its regulations as being excluded from the 
regulatory definition of VOCs (40 CFR 51.100(s)).
    Section 302(s) of the CAA specifies that the EPA has the authority 
to define the meaning of ``VOC,'' and hence what compounds shall be 
treated as VOCs for regulatory purposes. The policy of excluding 
negligibly reactive compounds from the regulatory definition of VOCs 
was first set forth in the ``Recommended Policy on Control of Volatile 
Organic Compounds'' (42 FR 35314, July 8, 1977) and was supplemented 
most recently with the ``Interim Guidance on Control of Volatile 
Organic Compounds in Ozone State Implementation Plans'' (Interim 
Guidance) (70 FR 54046, September 13, 2005). The EPA uses the 
reactivity of ethane as the threshold for determining whether a 
compound has negligible reactivity. Compounds that are less reactive 
than, or equally reactive to, ethane under certain assumed conditions 
may be deemed negligibly reactive and therefore suitable for exemption 
from the regulatory definition of VOCs. Compounds that are more 
reactive than ethane continue to be considered VOCs for regulatory 
purposes and therefore are subject to control requirements. The 
selection of ethane as the threshold compound was based on a series of 
smog chamber experiments that underlay the 1977 policy.
    The EPA has used three different metrics to compare the reactivity 
of a specific compound to that of ethane: (i) The reaction rate 
constant (known as kOH) with the hydroxyl radical (OH); (ii) 
the maximum incremental reactivity (MIR) on a reactivity per unit mass 
basis; and (iii) the MIR expressed on a reactivity per mole basis. A 
full description of each metric and how it is derived can be found in 
the direct final rulemaking (78 FR 11101, February 15, 2013) and is not 
repeated here.

B. Petition to List SolsticeTM 1233zd(E) as an Exempt Compound

    Honeywell Inc. submitted a petition to the EPA on July 19, 2011, 
requesting that SolsticeTM 1233zd(E) (CAS number 102687-65-
0) be exempted from VOC control based on its low reactivity relative to 
ethane.\1\ The petitioner indicated that SolsticeTM 
1233zd(E) may be used in a variety of applications, including as a 
solvent in aerosol and non-aerosol applications, as a blowing agent in 
insulating foams for refrigerators/freezers and hot water heaters and 
as a refrigerant in commercial chillers and waste heat recovery (Rankin 
cycle) systems. A fuller description of the petition regarding 
SolsticeTM 1233zd(E), including a discussion of other 
compounds for which it would substitute, is found in the direct final 
rulemaking (78 FR 11101, February 15, 2013) and is not repeated here.
---------------------------------------------------------------------------

    \1\ Trans 1-chloro-3,3,3-trifluoroprop-1-ene will also be 
marketed by Honeywell under the trade names SolsticeTM 
N12 Refrigerant, SolsticeTM Liquid Blowing Agent 
(SolsticeTM LBA), and SolsticeTM Performance 
Fluid.
---------------------------------------------------------------------------

C. Contribution to Tropospheric Ozone

    Detailed information on the ozone reactivity of 
SolsticeTM 1233zd(E) was presented in the direct final 
rulemaking

[[Page 53031]]

(78 FR 11101, February 15, 2013) and is summarized here.
    SolsticeTM 1233zd(E) has a higher kOH value 
than ethane, meaning that it initially reacts more quickly in the 
atmosphere than ethane. However, a molecule of SolsticeTM 
1233zd(E) is less reactive than a molecule of ethane in terms of 
complete ozone forming activity as shown by the molar-based MIR (g 
O3/mole VOC) values. Also, a gram of SolsticeTM 
1233zd(E) has a lower MIR value than a gram of ethane. Thus, under the 
Interim Guidance, SolsticeTM 1233zd(E) is eligible to be 
exempted from the regulatory definition of VOCs, based on both mass-
based and molar-based MIR.

D. Health and Environmental Risks

    The preamble to the direct final rulemaking (78 FR 11101, February 
15, 2013) provided background information on the Premanufacture Notice 
(PMN) review and SNAP program review of SolsticeTM 
1233zd(E). That preamble also presented other information relevant to 
any potential health or environmental risks. This information is 
summarized here.
    As a chemical not yet introduced into commerce, 
SolsticeTM 1233zd(E) completed a PMN review on January 30, 
2012. After considering all relevant data currently available, the EPA 
was unable to find any unreasonable risks to human health or the 
environment from the expected use of the substance. Based on this 
finding, the EPA did not find it necessary to take any actions to 
prevent unreasonable risk under the Toxic Substance Control Act (TSCA).
    The SNAP program review of SolsticeTM 1233zd(E) 
described the potential health effects of SolsticeTM 
1233zd(E) as being common to many refrigerants, foam agents and 
solvents, including many of those already listed as acceptable under 
SNAP. Potential health effects of this substitute include serious eye 
irritation, skin irritation and frostbite. EPA anticipates that users 
will be able to meet the manufacturer's recommended workplace exposure 
limit and address potential health risks by following requirements and 
recommendations in the material safety data sheet and in any other 
safety precautions common to the refrigeration and air conditioning 
industry, the foam blowing industry and the solvent-based cleaning 
industry and common when using adhesives and coatings.\2\
---------------------------------------------------------------------------

    \2\ Since publication of the direct final rule and parallel 
proposed rule, the SNAP program found SolsticeTM 
1233zd(E) acceptable for use as a solvent for metals, electronics, 
and precision cleaning and in adhesives, coatings, and inks (78 FR 
29034, May 17, 2013). The SNAP program is currently still reviewing 
SolsticeTM 1233zd(E) for use as a refrigerant for non-
mechanical heat transfer.
---------------------------------------------------------------------------

    SolsticeTM 1233zd(E) is not flammable. 
SolsticeTM 1233zd(E) is not expected to undergo wet or dry 
deposition to an appreciable extent.
    SolsticeTM 1233zd(E) has a 100-yr global warming 
potential (GWP) reported as 4.7 to 7 and an atmospheric lifetime of 
approximately 26 to 31 days or less. The net GWP effect of increased 
use of SolsticeTM 1233zd(E) in place of certain other 
compounds will be advantageous.

III. Proposed Action and Response to Comments

    Based on both the mass and molar MIR values for 
SolsticeTM 1233zd(E) being equal to or less than that of 
ethane, the EPA issued a direct final rule (78 FR 11101, February 15, 
2013) and a parallel notice-and-comment proposal (78 FR 11119, February 
15, 2013) to find that SolsticeTM 1233zd(E) is ``negligibly 
reactive'' and to exempt SolsticeTM 1233zd(E) from the 
regulatory definition of VOCs at 40 CFR 51.100(s).
    Comments: The EPA received three comments on the parallel notice-
and-comment proposal during its comment period. Only one commenter, an 
individual, expressed reservations about the proposed exemption.\3\ 
This commenter believes that the low ozone reactivity of 
SolsticeTM 1233zd(E) is not sufficient to exempt it from the 
regulatory definition of VOCs in light of what the commenter says are 
its hazards to humans and the environment. The commenter characterizes 
SolsticeTM 1233zd(E) as being a toxin and a halogen and 
notes that it has an occupational exposure limit (OEL) of 300 parts per 
million (ppm). The commenter says that removing SolsticeTM 
1233zd(E) from the regulatory definition of VOCs would trivialize the 
safety hazards posed by its use and that keeping SolsticeTM 
1233zd(E) within the regulatory definition of VOCs would incline people 
who work near and on it to treat it with caution.
---------------------------------------------------------------------------

    \3\ The EPA considered this comment to be an adverse comment and 
accordingly withdrew the direct final rule before it became 
effective. 78 FR 23149, April 18, 2013.
---------------------------------------------------------------------------

    Two comments, one from the petitioner Honeywell and the other from 
an individual, supported the proposed exemption. Honeywell's comments 
directly address the assertions made by the commenter who expressed the 
reservations noted above. Honeywell notes that SolsticeTM 
1233zd(E) does not meet the common definition of a ``toxin'' and that 
it is not itself a halogen. Honeywell also explains that the OEL of 300 
ppm is Honeywell's own recommendation and that this level is higher 
than three other particular chemicals that have already been excluded 
from the regulatory definition of VOCs. Honeywell states that 
SolsticeTM 1233zd(E) is not a listed chemical substance in 
the regulations of the Occupational Safety and Health Administration 
(OSHA), nor would it be classified as acutely toxic based on OSHA 
health hazard criteria. Honeywell also notes that SolsticeTM 
1233zd(E) is not a hazardous air pollutant under the Clean Air Act.
    EPA Response: The EPA agrees with the factual information provided 
in the comments from Honeywell. The EPA notes that the only fact cited 
in the single adverse comment is that the (Honeywell-recommended) OEL 
for SolsticeTM 1233zd(E) is 300 ppm. The commenter does not 
argue or present any evidence that exposures to workers or the public 
will approach this level. The EPA does not agree that keeping 
SolsticeTM 1233zd(E) within the regulatory definition of 
VOCs would increase worker or public awareness of its potential 
toxicity at high exposure levels or help them to limit their exposures, 
in the context of other mechanisms operating to inform and protect 
workers and the public from high exposures, because such individuals 
are unlikely to be aware of the details of the EPA's regulatory 
definition of VOCs and because individuals do not necessarily associate 
mere qualification as a VOC with hazard. There are more direct and 
customary ways for people likely to be exposed to the chemical to 
become aware of needed precautions (e.g., material safety data sheets). 
Issues of workplace exposure were considered in the EPA's reviews of 
this compound under the PMN and SNAP program and the EPA felt that 
existing measures were appropriate to prevent unreasonable risk.
    As stated previously, the EPA finds that SolsticeTM 
1233zd(E) qualifies as negligibly reactive with respect to its 
contribution to tropospheric ozone formation. In addition, we believe 
that risks not related to tropospheric ozone associated with currently 
allowed uses of the chemical are acceptable and that any new or 
increased risk from potential new uses are adequately addressed by 
other existing programs and policies, specifically the SNAP program. We 
also believe that the comparable or lower GWP of SolsticeTM 
1233zd(E) compared to other acceptable substitutes is an additional 
reason to approve the SolsticeTM 1233zd(E) petition given 
that

[[Page 53032]]

applying the Interim Guidance itself supports such approval.

IV. Final Action

    The EPA is taking final action to approve the petition for 
exemption of SolsticeTM 1233zd(E) from the regulatory 
definition of VOCs.
    If an entity uses or produces SolsticeTM 1233zd(E) and 
is subject to the EPA regulations limiting the use of VOC in a product 
other than an aerosol coating, limiting the VOC emissions from a 
facility, or otherwise controlling the use of VOC for purposes related 
to attaining the ozone NAAQS, then the compound will not be counted as 
a VOC in determining whether these regulatory obligations have been 
met. Emissions of this compound will not be considered in determining 
whether a proposed new or modified source triggers the applicability of 
Prevention of Significant Deterioration (PSD) requirements, in areas 
where the PSD program is implemented by the EPA or a delegated state, 
local or tribal agency. This action may also affect whether 
SolsticeTM 1233zd(E) is considered as a VOC for state 
regulatory purposes to reduce ozone formation, if a state relies on the 
EPA's regulatory definition of VOCs. States are not obligated to 
exclude from control as a VOC those compounds that the EPA has found to 
be negligibly reactive. However, states may not take credit for 
controlling these compounds in their ozone control strategies.
    This action is consistent with the Interim Guidance in that two of 
the three reactivity metric values for SolsticeTM 1233zd(E) 
compare favorably to the corresponding values for ethane. This action 
is also supported by our inability in the Premanufacture Notification 
Review Program to find any unreasonable risks to human health or the 
environment from the expected use of the substance, our finding in the 
SNAP program review of this chemical that use of this chemical in 
currently allowed applications poses lower or comparable overall risk 
to human health and the environment than other acceptable options for 
the same uses, and on our confidence that the SNAP program would 
prevent the use of this chemical in any additional applications subject 
to review by the SNAP program where such use would pose a significant 
risk to human health or the environment.

V. Statutory and Executive Order Reviews

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

    This action is not a ``significant regulatory action'' under the 
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is 
therefore not subject to review under Executive Orders 12866 and 13563 
(76 FR 3821, January 21, 2011).

B. Paperwork Reduction Act

    This action does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. 
Burden is defined at 5 CFR 1320.3(b). It does not contain any 
recordkeeping or reporting requirement.

C. Regulatory Flexibility Act

    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. Small entities include small businesses, 
small organizations and small governmental jurisdictions.
    For purposes of assessing the impacts of this action on small 
entities, small entity is defined as: (1) A small business as defined 
by the Small Business Administration (SBA) regulation (see 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; and (3) a small organization that is 
any not-for-profit enterprise which is independently owned and operated 
and is not dominant in its field.
    After considering the economic impacts of today's final rule on 
small entities, I certify that this action will not have a significant 
economic impact on a substantial number of small entities. In 
determining whether a rule has a significant economic impact on a 
substantial number of small entities, the impact of concern is any 
significant adverse economic impact on small entities, since the 
primary purpose of the regulatory flexibility analyses is to identify 
and address regulatory alternatives ``which minimize any significant 
economic impact of the rule on small entities.'' 5 USC 603 and 604. 
Thus, an agency may certify that a rule will not have a significant 
economic impact on a substantial number of small entities if the rule 
relieves regulatory burden, or otherwise has a positive economic effect 
on all of the small entities subject to the rule. This final rule 
removes SolsticeTM 1233zd(E) from the regulatory definition 
of VOCs and thereby relieves users of the compound from requirements to 
control emissions of the compound. We have, therefore, concluded that 
today's final rule will relieve regulatory burden for all affected 
small entities.

D. Unfunded Mandates Reform Act

    This action contains no federal mandates under the provisions of 
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 
1531-1538 for state, local or tribal governments or the private sector. 
The action imposes no enforceable duty on any state, local or tribal 
governments or the private sector. Therefore, this action is not 
subject to the requirements of sections 202 and 205 of the UMRA.
    This action is also not subject to the requirements of section 203 
of UMRA because it contains no regulatory requirements that might 
significantly or uniquely affect small governments. This final rule 
removes SolsticeTM 1233zd(E) from the regulatory definition 
of VOCs and thereby relieves users of the compound from requirements to 
control emissions of the compound.

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, as 
specified in Executive Order 13132. This final rule removes 
SolsticeTM 1233zd(E) from the regulatory definition of VOCs 
and thereby relieves users from requirements to control emissions of 
the compound. Thus, Executive Order 13132 does not apply to this rule.

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

    This action does not have tribal implications, as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000). It would not 
have substantial direct effects on tribal governments, 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.

[[Page 53033]]

Thus, Executive Order 13175 does not apply to this rule.

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

    This action is not subject to EO 13045 (62 FR 19885, April 23, 
1997) because it is not economically significant as defined in EO 
12866. While this final rule is not subject to the Executive Order, the 
EPA has reason to believe that ozone has a disproportionate effect on 
active children who play outdoors (62 FR 38856; 38859, July 18, 1997). 
The EPA has not identified any specific studies on whether or to what 
extent SolsticeTM 1233zd(E) may affect children's health.

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

    This action is not subject to Executive Order 13211 (66 FR 28355 
(May 22, 2001)), because it is not a significant regulatory action 
under Executive Order 12866.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law 104-113, section 12(d), (15 U.S.C. 
272 note) directs the EPA to use voluntary consensus standards in its 
regulatory activities unless to do so would be inconsistent with 
applicable law or otherwise impractical. Voluntary consensus standards 
are technical standards (e.g., materials specifications, test methods, 
sampling procedures and business practices) that are developed or 
adopted by voluntary consensus standards bodies. The NTTAA directs the 
EPA to provide Congress, through OMB, explanations when the agency 
decides not to use available and applicable voluntary consensus 
standards. This rulemaking does not involve technical standards. 
Therefore, the EPA has not considered the use of any voluntary 
consensus standards.

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

    Executive Order (EO) 12898 (59 FR 7629, Feb. 16, 1994) establishes 
federal executive policy on environmental justice. Its 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.
    The EPA has determined that this final rule will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations because it will not 
affect the level of protection provided to human health or the 
environment.

K. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. The EPA will submit a report containing this rule and 
other required information to the U.S. Senate, the U.S. House of 
Representatives and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2). This rule will be effective on September 27, 2013.

L. Judicial Review

    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the District of Columbia Circuit Court within 60 days from the date the 
final action is published in the Federal Register. Filing a petition 
for review by the Administrator of this final action does not affect 
the finality of this action for the purposes of judicial review nor 
does it extend the time within which a petition for judicial review
