Air Quality: Revision to the Regulatory Definition of Volatile
Organic Compounds--Exclusion of 2-amino-2-methyl-1-propanol (AMP)
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is taking direct
final action to revise the regulatory definition of volatile organic
compounds (VOCs) under the Clean Air Act (CAA). This direct final
action adds 2-amino-2-methyl-1-propanol (also known as AMP; CAS number
124-68-5) 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.
DATES: This rule is effective June 25, 2014 without further notice,
unless the EPA receives adverse comment on this action by May 27, 2014.
If the EPA receives adverse comment, we will publish a timely
withdrawal in the Federal Register informing the public that the final
rule will not take effect.

I. Why is the EPA using a direct final rule?
The EPA is publishing this direct final rule without a prior
proposed rule because we view this as a noncontroversial action and
anticipate no adverse comment. This action revises the EPA's regulatory
definition of VOCs for purposes of preparing SIPs to attain the NAAQS
for ozone under title I of the CAA. However, in the ``Proposed Rules''
section of this Federal Register, we are publishing a separate document
that will serve as the proposed rule to make this revision to the
regulatory definition of VOCs if adverse comments are received on the
parallel proposal or this direct final rule. We will not institute a
second comment period on this action. Any parties interested in
commenting must do so at this time. For further information about
commenting on this rule, see the ADDRESSES section of this document.
If the EPA receives adverse comment, we will publish a timely
withdrawal in the Federal Register informing the public that this
direct final rule will not take effect. We would address all public
comments in any subsequent final rule based on the proposed rule.
II. Does this action apply to me?
Entities potentially affected by this direct 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; and industries manufacturing and/or using pigments
in water-based coatings, additives in metalworking fluids and in food
contact paper, neutralizers in personal care products, and
intermediates in chemical synthesis.
III. 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. The VOCs are those organic compounds of
carbon which 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 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 VOCs 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)).
The CAA requires the regulation of VOCs for various purposes.
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 laid out in the ``Recommended Policy on Control of Volatile
Organic Compounds'' (42 FR 35314, July 8, 1977) and was supplemented
subsequently with the ``Interim Guidance on Control of Volatile Organic
Compounds in Ozone State Implementation Plans'' (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.
Differences between these three metrics are discussed below.
The kOH is the reaction rate constant of the compound
with the OH radical in the air. This reaction is typically the first
step in a series of chemical reactions by which a compound breaks down
in the air and participates in the ozone-forming process. If this step
is slow, the compound will likely not form
[[Page 17039]]
ozone at a very fast rate. The kOH values have long been
used by the EPA as a metric of photochemical reactivity and ozone-
forming activity, and they have been the basis for most of the EPA's
previous exemptions of negligibly reactive compounds from the
regulatory definition of VOCs. The kOH metric is inherently
a molar-based comparison, i.e., it measures the rate at which molecules
react.
The MIR, both by mole and by mass, is a more recently developed
metric of photochemical reactivity derived from a computer-based
photochemical model. This metric considers the complete ozone forming
activity of a compound on a single day, not merely the first reaction
step. Further explanation of the MIR metric can be found in Carter,
1994.
The MIR values for compounds are typically expressed as grams of
ozone formed per gram of VOC (mass basis), but they may also be
expressed as grams of ozone formed per mole of VOC (molar basis). For
comparing the reactivities of two compounds, using the molar-based MIR
values considers an equal number of molecules of the two compounds.
Alternatively, using the mass-based MIR values compares an equal mass
of the two compounds, which will involve different numbers of
molecules, depending on the relative molecular weights. The molar-based
MIR comparison is consistent with the original smog chamber experiments
that underlie the original selection of ethane as the threshold
compound, in that these experiments compared equal molar concentrations
of individual VOCs. It is also consistent with previous reactivity
determinations based on kOH values, which are inherently
molar-based. By contrast, the mass-based MIR comparison is more
consistent with how MIR values and other reactivity metrics have been
applied in reactivity-based emission limits, such as the national VOC
emissions standards for aerosol coatings (40 CFR part 59 subpart E).
Many other VOCs regulations contain limits based upon a weight of VOC
per volume of product, such as the EPA's regulations for limiting VOC
emissions from architectural coatings (40 CFR part 59 subpart D).
However, the fact that regulations are structured to measure VOC
content by weight for ease of implementation and enforcement does not
necessarily control whether VOC exemption decisions should be made on a
weight basis as well.
The choice of the molar basis versus the mass basis for the ethane
comparison can be significant. In some cases, a compound might be
considered less reactive than ethane under the mass basis but not under
the molar basis. For compounds with molecular weights higher than that
of ethane, use of the mass basis results in more VOCs being classified
as less reactive than ethane than use of the molar basis.
The EPA has considered the choice between a molar or mass basis for
the comparison to ethane in past rulemakings and guidance. In the
Interim Guidance, the EPA stated:
[A] comparison to ethane on a mass basis strikes the right
balance between a threshold that is low enough to capture compounds
that significantly affect ozone concentrations and a threshold that
is high enough to exempt some compounds that may usefully substitute
for more highly reactive compounds.
When reviewing compounds that have been suggested for VOC-exempt
status, EPA will continue to compare them to ethane using
kOH expressed on a molar basis and MIR values expressed
on a mass basis.
The EPA's 2005 Interim Guidance also noted that concerns have
sometimes been raised about the potential impact of a VOC exemption on
environmental endpoints other than ozone concentrations, including fine
particle formation, air toxics exposures, stratospheric ozone depletion
and climate change. The EPA has recognized, however, that there are
existing regulatory and non-regulatory programs that are specifically
designed to address these issues, and the EPA continues to believe in
general that the impacts of VOC exemptions on environmental endpoints
other than ozone formation will be adequately addressed by these
programs. The VOC exemption policy is intended to facilitate attainment
of the ozone NAAQS. As such, in general, VOC exemption decisions will
continue to be based solely on consideration of a compound's
contribution to ozone formation. However, if EPA determines that a
particular VOC exemption is likely to result in a significant increase
in the use of a compound and that the increased use would pose a
significant risk to human health or the environment that would not be
addressed adequately by existing programs or policies, the EPA reserves
the right to exercise its judgment in deciding whether to grant an
exemption.
B. Petition To List AMP as an Exempt Compound
Dow Chemical Company submitted a petition to the EPA on October 12,
2012, requesting that 2-amino-2-methyl-1-propanol (also known as AMP;
CAS number 124-68-5) be exempted from the regulatory definition of VOCs
based on its low reactivity relative to ethane. The petitioner
indicated that AMP may be used in a variety of applications including
in industries involved in the manufacture or use of pigments in water-
based coatings, as an additive in metalworking fluids, in food contact
paper, as a neutralizer in personal care products, and as an
intermediate in chemical synthesis.
To support its petition, Dow Chemical referenced several documents,
including a technical report on the maximum incremental reactivity of
AMP (Carter, 2012) and two peer-reviewed journal articles on its
reaction rates. According to these documents, the reactivity of AMP is
0.25 gm O3/gm AMP in the maximum incremental reactivity
(MIR) scale. The reactivity rate is slightly less than that of ethane,
0.28 gm O3/gm ethane, the compound that the EPA has used for
comparison to define ``negligible'' ozone reactivity for the purpose of
exempting compounds from the regulatory definition of VOCs. The rate
constant for the gas-phase reaction of OH radicals with AMP,
(kOH) has been measured to be 2.8 x 10-\11\
cm\3\/molecule-sec at ~300 K (Harris and Pitts, 1983), giving it a
relatively short lifetime in the atmosphere and thus reducing its
ability to contribute to ozone formation. Under the conventional
assumption of OH concentration of 3 x 10\6\ molecules/cm\3\, AMP would
decay exponentially with a mean lifetime of about 4 hours (Carter,
2008). Based on the measured reactivity rate of AMP (Harris and Pitts,
1983), AMP has a larger kOH than ethane (ethane = 2.4 x
10-\13\) and therefore it is initially more reactive than
ethane, but as explained in detail in Carter, 2008, AMP's first
reaction primarily terminates radicals rather than cycling them and
therefore generally reduces ozone. With regard to stratospheric ozone
depletion, the petitioner stated that the ozone depletion potential of
AMP is insignificant based on the expected possible initial reactions
described in Carter 2008 and the general theory supporting the
estimated mechanisms discussed in Carter 2012. Given that AMP has a
relatively short atmospheric lifetime, and because it does not contain
chlorine or bromine, it is not expected to contribute to the depletion
of the stratospheric ozone layer.
IV. The EPA's Assessment of the Petition
The EPA is taking direct final action to approve the petition for
exemption of AMP from the regulatory definition of VOCs. This action is
consistent with the 2005 Interim Guidance based on comparison of the
three reactivity
[[Page 17040]]
metric values for AMP to the corresponding values for ethane. As a
short-lived substance, there is no evidence that AMP would have a
substantial climate impact: AMP meets the Interim Guidance criteria for
no significant risks in terms of environmental endpoints other than
ozone formation. Information on these topics is given in the following
sections.
A. Contribution to Tropospheric Ozone
The reaction rate of AMP for reaction with OH radical
(kOH) has been measured to be 2.8 x 10-\11\
cm\3\/molecule-sec (Harris and Pitts, 1983); other reactions with ozone
and nitrate radical were negligibly small. The corresponding reaction
rate of ethane with OH is 2.4 x 10-\13\ cm\3\/molecule-sec
(Atkinson et al., 2006).
The overall atmospheric reactivity of AMP was studied in an
experimental smog chamber, and the chemical mechanism derived from this
study was used to model the complete formation of ozone for an entire
single day under realistic atmospheric conditions (Carter, 2012). Using
the standard 39-city array of input conditions, Carter calculated a MIR
value of 0.25 g O3/g VOC for AMP for ``averaged
conditions,'' versus 0.28 g O3/g VOC for ethane.
Table 1 presents the three reactivity metrics for AMP as they
compare to ethane.

AMP..................................... 2.8 x 10-11........................... 22.25 0.25
----------------------------------------------------------------------------------------------------------------
Notes:
1. kOH value at 298 K for ethane is from Atkinson et al., 2006 (page 2636).
2. kOH value at 300 K for AMP is from Harris and Pitts, 1983 (page 50).
3. Mass-based MIR value (g O3/g VOC) of ethane is from Carter, 2011.
4. Mass-based MIR value (g O3/g VOC) of AMP is from Carter, 2012.
5. Molar-based MIR (g O3/mole VOC) values were calculated from the mass-based MIR (g O3/g VOC) values using the
number of moles per gram of the relevant organic compound.
From the data in Table 1, it can be seen that AMP has a higher
kOH value than ethane, meaning that it initially reacts more
quickly in the atmosphere than ethane. Also, a molecule of AMP is more
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. However, the nitrogen-centered radical in AMP scavenges
radicals, primarily NOX and is expected to form nitramine
that is assumed to be inert according to Harris and Pitts, 1983. This
is in line with the effects of AMP addition on ozone concentration
reduction observed in the chamber experiments of Carter, 2008. The
early reactivity of AMP is thus short lived, because the reaction
pathway is terminated by the intermediate production of assumed inert
nitramine. Unlike other VOCs, AMP is a base and might be lost to some
degree by reaction with HNO3, forming non-volatile amine
salts, reducing its availability in the gas phase for O3
formation. As a result, one gram of AMP has a lower MIR value than one
gram of ethane. Thus, under the 2005 Interim Guidance AMP is eligible
to be exempted from the regulatory definition of VOCs, on the basis of
the mass-based MIR.
B. Likelihood of Risk to Human Health or the Environment
Information in Dow Chemical Company's petition and its appendices
as well as the reference material indicates that AMP has low toxicity
(Griffin 1990), no irritation or skin sensitization, and no detectable
genotoxic activity in vitro or in vivo. AMP was subject to the Ames
test, the mouse lymphoma assay and the mouse micronucleus test (Gudi,
1998; San and Clark, 1997; and Wagner 1996) and was found negative in
these studies among several others. AMP has a toxicity profile amply
documented in the appendices provided with the petition material and
placed in the docket for this rulemaking. AMP also has a favorable
toxicity profile supported by the Hazard Characterization Document
dedicated to AMP published by EPA in March of 2012, titled ``Screening-
level Hazard Characterization of High Production Volume Chemicals--2-
Amino-2-methyl-1-propanol (AMP) CASRN 124-68-5'' under the High
Production Volume (HPV) Challenge Program.\1\
---------------------------------------------------------------------------
\1\ U.S. EPA. High Production Volume (HPV) Challenge Program;
http://www.epa.gov/chemrtk/hpvis/hazchar/124685_AMP_March_2012.pdf.
---------------------------------------------------------------------------
In addition, AMP is a reasonably strong base and forms salts with
acids. Therefore, in many formulations very little AMP will evaporate
and will be available for atmospheric reaction due to its ionic or salt
form. Therefore, exposure is low due to low volatility at room
temperature. However, repeated inhalation of vapor or mist could cause
respiratory irritation. Burnett et al. (2009) reviewed safety data and
found that AMP is safe to use in cosmetics after he performed several
acute inhalation studies with AMP as well as with AMP in alcohol and
propellant. The studies indicated that AMP is nontoxic by inhalation.
The studies also tested other routes of exposure and found them to be
nontoxic as well.
AMP is not regulated as a hazardous air pollutant (HAP) under title
I of the Clean Air Act. Also, it is not listed as a toxic chemical
under section 313 of the Emergency Planning and Community Right-to-Know
Act (EPCRA).
The Toxic Substances Control Act (TSCA) requires the EPA to assess
and prevent any unreasonable risks to human health and the environment
before a new chemical substance is introduced into commerce. Section 5
of TSCA requires manufacturers and importers to notify the EPA before
manufacturing or importing a new chemical substance. This
premanufacture notice, or PMN, must be submitted at least 90 days prior
to the manufacture (including import) of the chemical. Under the TSCA
New Chemicals Program, the EPA then performs a risk assessment on the
new chemical substance to determine whether an unreasonable risk may,
or will, be presented by the expected manufacture, processing,
distribution in commerce, use, and disposal of the new
[[Page 17041]]
substance. AMP is TSCA compliant, but is not a new compound and did not
undergo PMN review.
The Significant New Alternatives Policy (SNAP) program is the EPA's
program to evaluate and regulate substitutes for ozone-depleting
chemicals. In Section 612(c) of the CAA, the agency is authorized to
identify and publish lists of acceptable and unacceptable substitutes
for class I or class II ozone-depleting substances. AMP is not a
substitute for any of the ozone-depleting chemicals, and it has not
been evaluated under the SNAP program. For the reasons stated in
section III, AMP does not contribute to the depletion of the
stratospheric ozone layer.
C. Climate Impacts
The EPA has previously exempted compounds with modest climate
impacts from the regulatory definition of VOCs. Because AMP has a
relatively short atmospheric lifetime (i.e., about 4 hours under the
conventional assumption of a hydroxyl radical concentration of 3 x
10\6\ molecules/cm\3\), its direct contribution to global warming
should be insignificant and thus any indirect contributions to global
warming through interactions with ozone and methane chemistry should be
of the order of or smaller than that of ethane (in addition to any
conversion of carbon in AMP to carbon dioxide).
D. Conclusion
In summary, the EPA finds that AMP is negligibly reactive with
respect to its contribution to tropospheric ozone formation and thus
may be exempted from EPA's definition of VOCs in 40 CFR section
51.100(s). We consider risks not related to tropospheric ozone
associated with currently allowed uses of the chemical to be
acceptable. AMP has not been the subject of any SNAP review. AMP's
performance as a multifunctional neutralizer combined with its reduced
ozone potential and favorable toxicity data makes this product a
preferred one compared to more toxic chemicals used for the same
purpose. In addition, there is no evidence that climate effects or
other environmental impacts resulting from AMP emissions should
disqualify AMP for exemption from the regulatory definition of VOCs
based on the 2005 Interim Guidance criteria.
V. Direct Final Action
The EPA is responding to the petition by revising its regulatory
definition of VOCs at 40 CFR 51.100(s) to add AMP to the list of
compounds that are exempt from the regulatory definition of VOCs
because they are negligibly reactive, on the basis that it is less
reactive than ethane on a mass MIR basis. If an entity uses or produces
any of this compound and is subject to EPA regulations limiting the use
of VOC in a product, limiting the VOC emissions from a facility, or
otherwise controlling the use of VOC for purposes related to attaining
the ozone NAAQS, then this compound will not be counted as a VOC in
determining whether these regulatory obligations have been met. This
action may also affect whether this compound is considered 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, no state may take credit for
controlling this compound in its ozone control strategy. For example,
reduction in emissions for this compound will not be considered or
counted in determining whether states have met rate of progress
requirement for VOCs in SIPs for purpose of meeting the ozone NAAQS.
VI. 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
proposed 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 notice on small
entities, small entity is defined as: (1) A small business that is a
small industrial entity as defined in the U.S. Small Business
Administration (SBA) size standards. (See 13 CFR 121.); (2) A
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 this direct 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 U.S.C. 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 direct final
rule removes AMP 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 this direct 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 direct final
rule removes AMP from the regulatory definition of VOCs and thereby
relieves users of the compound from requirements to control emissions
of the compound.
[[Page 17042]]
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 direct final rule removes AMP
from the regulatory definition of VOCs and thereby relieves users of
the compound from requirements to control emissions of the compound.
Thus, Executive Order 13132 does not apply to this action.
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.
This direct final rule removes AMP from the regulatory definition of
VOCs and thereby relieves users from requirements to control emissions
of the compound. Thus, Executive Order 13175 does not apply to this
action.
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 direct final rule is not subject to the Executive
Order, the EPA has reason to believe that at higher concentrations
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 AMP 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 energy action''
under EO 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 direct 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. This direct final rule removes AMP from the regulatory
definition of VOCs and thereby relieves users of the compound from
requirements to control emissions of the compound.
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 June 25, 2014.
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
must be filed, and shall not postpone the effectiveness of such action.
Thus, any petitions for review of this action related to the exemption
of AMP from the regulatory definition of VOCs must be filed in the
Court of Appeals for the District of Columbia Circuit within 60 days
from the date final action is published in the Federal Register.
