The Environmental Protection Agency (EPA) is amending the EPA's regulatory definition of volatile organic compounds (VOC) under the Clean Air Act (CAA). The regulatory definition of VOC currently excludes t-butyl acetate (also known as tertiary butyl acetate or TBAC; CAS Number: 540-88-5) for purposes of VOC emissions limitations or VOC content requirements on the basis that it makes a negligible contribution to tropospheric ozone formation. However, the current definition includes TBAC as a VOC for purposes of all recordkeeping, emissions reporting, photochemical dispersion modeling and inventory requirements which apply to VOC. This final action removes the recordkeeping, emissions reporting, photochemical dispersion modeling and inventory requirements related to the use of TBAC as a VOC.

Air Quality: Revision to the Regulatory Definition of Volatile 
Organic Compounds--Requirements for t-Butyl Acetate

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is amending the 
EPA's regulatory definition of volatile organic compounds (VOC) under 
the Clean Air Act (CAA). The regulatory definition of VOC currently 
excludes t-butyl acetate (also known as tertiary butyl acetate or TBAC; 
CAS Number: 540-88-5) for purposes of VOC emissions limitations or VOC 
content requirements on the basis that it makes a negligible 
contribution to tropospheric ozone formation. However, the current 
definition includes TBAC as a VOC for purposes of all recordkeeping, 
emissions reporting, photochemical dispersion modeling and inventory 
requirements which apply to VOC. This final action removes the 
recordkeeping, emissions reporting, photochemical dispersion modeling 
and inventory requirements related to the use of TBAC as a VOC.

DATES: This final rule is effective on April 25, 2016.

ADDRESSES: The EPA has established a docket for this action under

I. General Information

A. Does this action apply to me?

    Entities affected by this final rule include, but are not 
necessarily limited to, state and local air pollution control agencies 
that prepare VOC emission inventories and ozone attainment 
demonstrations for state implementation plans (SIPs). These agencies 
are relieved of the requirements to separately inventory emissions of 
TBAC. This final action may also affect manufacturers, distributors and 
users of TBAC and TBAC-containing products, which may include paints, 
inks and adhesives. This action allows state air agencies to no longer 
require these entities to report emissions of TBAC.

B. Where can I get a copy of this document and other related 
information?

    In addition to being available in the docket, an electronic copy of 
this final rule will also be available on the Worldwide Web (WWW) 
through the Technology Transfer Network (TTN). Following the 
Administrator's signature, a copy of this final rule will be posted on 
the TTN's policy and guidance page for promulgated rules at the 
following address: http://www.epa.gov/airquality/ozonepollution/actions.html#impl. The TTN provides information and technology exchange 
in various areas of air pollution control. If more information 
regarding the TTN is needed, call the TTN HELP Line at (919) 541-4814.

C. 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 final action related to the 
elimination of recordkeeping of TBAC must be filed in the Court of 
Appeals for the District of Columbia Circuit within 60 days from the 
date this final action is published in the Federal Register.

II. Background

A. The EPA's VOC Exemption Policy

    Tropospheric ozone, commonly known as smog, is formed when VOC 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 VOC that can be 
released into the atmosphere. VOCs are organic compounds of carbon, 
many of

[[Page 9340]]

which form ozone through atmospheric photochemical reactions. Different 
VOC have different levels of reactivity. That is, they do not react to 
form ozone at the same speed or to the same extent. Some VOC 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 VOC so 
as to focus control efforts on compounds that do significantly affect 
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 VOC. The EPA lists compounds that it has determined to be negligibly 
reactive in its regulations as being excluded from the regulatory 
definition of VOC (40 CFR 51.100(s)).
    The CAA requires the regulation of VOC 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 VOC for regulatory purposes. The policy of excluding 
negligibly reactive compounds from the regulatory definition of VOC 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) (from here forward referred to as the 2005 Interim Guidance). 
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 by the EPA from the regulatory definition of VOC. 
Compounds that are more reactive than ethane continue to be considered 
VOC 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 uses two different metrics to compare the reactivity of a 
specific compound to that of ethane: (1) The reaction rate constant 
(known as kOH) with the hydroxyl radical (OH); and (2) the 
maximum incremental reactivity (MIR) on ozone production per unit mass 
basis. Differences between these metrics and the rationale for their 
selection is discussed further in the 2005 Interim Guidance.

B. History of the VOC Exemption for TBAC Including the Unique 
Recordkeeping, Emissions Reporting, Photochemical Dispersion Modeling 
and Inventory Requirements

    On January 17, 1997, ARCO Chemical Company (now known as and from 
here forward referred to as LyondellBasell) submitted a petition to the 
EPA, which requested that the EPA add TBAC to the list of compounds 
that are designated negligibly reactive in the regulatory definition of 
VOC at 40 CFR 51.100(s). The materials submitted in support of this 
petition are contained in Docket EPA-HQ-OAR-2003-0084. LyondellBasell's 
case for TBAC being less reactive than ethane was based primarily on 
the use of relative incremental reactivity factors set forth in a 1997 
report by Carter, et al.\1\ Although the kOH values for TBAC 
are higher than for ethane, Carter's results indicated that the MIR 
value for TBAC, expressed in units of grams of ozone per gram of TBAC, 
was between 0.43 and 0.48 times the MIR for ethane, depending on the 
chemical mechanism used to calculate the MIR. In other words, TBAC 
formed less than half as much ozone as an equal mass of ethane under 
the conditions assumed in the calculation of the MIR scale.

(1997). Investigation of the Atmospheric Ozone Formation Potential

College of Engineering Center for Environmental Research and 
Technology, University of California, 97-AP-RT3E-001-FR, http://
www.cert.ucr.edu/~carter/pubs/tbuacetr.pdf.
---------------------------------------------------------------------------

    On September 30, 1999, the EPA proposed to revise the regulatory 
definition of VOC to exclude TBAC, relying on the comparison of MIR 
factors expressed on a mass basis to conclude that TBAC is negligibly 
reactive (64 FR 52731, September 30, 1999). However, in the final rule, 
the EPA concluded at that time that even ``negligibly reactive'' 
compounds may contribute significantly to ozone formation if present in 
sufficient quantities and that emissions of these compounds need to be 
represented accurately in photochemical modeling analyses. In addition 
to these general concerns about the potential cumulative impacts of 
negligibly reactive compounds, the need to maintain recordkeeping and 
reporting requirements for TBAC was further justified by the potential 
for widespread use of TBAC, the fact that its relative reactivity falls 
close to the borderline of what has been considered negligibly 
reactive, and continuing efforts to assess long-term health risks.\2\ 
Based on these conclusions, in 2004, the EPA promulgated a final rule 
that excluded TBAC from the definition of VOC for purposes of VOC 
emissions limitations or VOC content requirements, but continued to 
define TBAC as a VOC for purposes of all recordkeeping, emissions 
reporting, photochemical dispersion modeling and inventory requirements 
that apply to VOC (69 FR 69298, November 29, 2004) (from here forward 
referred to as the 2004 Final Rule).
---------------------------------------------------------------------------

    \2\ Between the EPA's proposed and final rule exempting TBAC as 
a VOC, the state of California raised concerns to the EPA about the 
potential carcinogenicity of tertiary-butanol, or TBA, the principal 
metabolite of TBAC. At the time, the EPA decided that there was 
insufficient evidence of health risks to affect the exemption 
decision, but persuaded LyondellBasell to voluntarily perform 
additional toxicity testing, use the testing results in a health 
risk assessment, and have the testing and assessment results 
reviewed in a peer consultation.
---------------------------------------------------------------------------

    In the 2004 Final Rule, the EPA argued that the recordkeeping and 
reporting requirements were not new requirements for TBAC as industry 
and states were already subject to such requirements to report TBAC as 
a VOC prior to the exemption. However, in practice, the rule created a 
new, distinct recordkeeping and reporting burden by requiring that TBAC 
be ``uniquely identified'' in emission reports, rather than aggregated 
with other compounds as VOC. The final rule explained that the EPA was 
in the process of reviewing its overall VOC exemption policy and that 
the potential for retaining recordkeeping and reporting requirements 
for compounds exempted from the definition of VOC in the future would 
be considered in that process. That process led to the development of 
the 2005 Interim Guidance, which encouraged the development of 
speciated inventories for highly reactive compounds and identified the 
voluntary submission of emissions estimates for exempt compounds as an 
option for further consideration, but did not recommend mandatory 
reporting requirements associated with future exemptions. Thus, TBAC 
was the only compound that was excluded from the VOC definition for 
purposes of emission controls but was still considered a VOC for 
purposes of recordkeeping and reporting requirements.

C. Petition To Remove Recordkeeping and Reporting Requirements From the 
TBAC Exemption

    The EPA received a petition from LyondellBasell in December 2009,

[[Page 9341]]

which was re-affirmed in November 2011, requesting the removal of 
recordkeeping and reporting requirements from the final rule to exempt 
TBAC from the regulatory VOC definition. LyondellBasell contends that 
the emissions reporting requirements are redundant and present an 
unnecessary burden. In 2015, the EPA issued a proposed rule (80 FR 
6481, February 5, 2015) \3\ in order to relieve manufacturers and users 
from recordkeeping and reporting requirements that were part of the 
2004 Final Rule.

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

III. The EPA's Assessment of the Petition

    In most cases, when a negligibly reactive VOC is exempted from the 
definition of VOC, emissions of that compound are no longer recorded, 
collected, or reported to states or the EPA as part of VOC emissions. 
When the EPA exempted TBAC from the VOC definition for purposes of 
control requirements in the 2004 Final Rule, the EPA created a new 
category of compounds and a new reporting requirement that required 
that emissions of TBAC be reported separately by states and, in turn, 
by industry. However, the EPA did not issue any guidance on how TBAC 
emissions should be tracked and reported, and implementation of this 
requirement by states has been inconsistent. A few states have modified 
their rules and emissions inventory processes to track TBAC emissions 
separately and provide that information to the EPA. Others have 
included TBAC with other undifferentiated VOC in their emissions 
inventories. Thus, the data that have been reported to date as a result 
of these requirements are incomplete and inconsistent. In addition, the 
EPA has not established protocols for receiving and analyzing TBAC 
emissions data collected under the requirements of the 2004 Final Rule.
    Although the reactivity of TBAC and other negligibly reactive 
compounds is low, if emitted in large quantities, they could still 
contribute significantly to ozone formation in some locations. However, 
without speciated emissions estimates or extensive speciated 
hydrocarbon measurements, it is difficult to assess the impacts of any 
one exempted compound or even the cumulative impact of all of the 
exempted compounds.
    In the 2004 Final Rule, the EPA stated the primary objective of the 
recordkeeping and reporting requirements for TBAC was to address these 
cumulative impacts of ``negligibly reactive'' compounds and suggested 
that future exempt compounds may also be subject to such requirements. 
However, such requirements have not been included in any other proposed 
or final VOC exemptions since the TBAC decision. Having high quality 
data on TBAC emissions alone is unlikely to be very useful in assessing 
the cumulative impacts of these compounds on ozone formation. Thus, the 
requirements are not achieving their primary objective to inform more 
accurate photochemical modeling in support of SIP submissions.
    In the 2004 Final Rule, EPA also noted that recordkeeping and 
reporting requirements were justified in light of the continuing 
efforts to characterize long-term health risks associated with TBAC and 
its metabolite tertiary-butyl alcohol (TBA). Since the rule was 
finalized, those efforts have resulted in at least two studies 
regarding the long-term health risks associated with TBAC and TBA. 
LyondellBasell performed additional toxicity testing and a health risk 
assessment and submitted the peer-consultation results to the EPA in 
2009.\4\ In addition, in 2006, the state of California published its 
own assessment of the potential health effects associated with TBA and 
TBAC.\5\ Also, the EPA is currently in the process of assessing the 
evidence for health risks from TBA through its Integrated Risk 
Information System (IRIS) program.\6\ This is the first IRIS assessment 
for TBA. A draft of this assessment is expected to be released for 
public comment later this year. However, the existing toxicity 
information being examined in the IRIS assessment does not rely on any 
of the data collected through the recordkeeping and reporting 
requirements at issue in this rule, and, thus, continuation of those 
requirements does not appear relevant to any likely future 
determinations about the health risks associated with TBAC or TBA.

IV. Public Comments

    The EPA received five comments on the proposed rule referenced 
above from industry in support of this final action. No adverse 
comments were received.

V. Final Action

    The EPA is removing the recordkeeping, emissions reporting, 
photochemical dispersion modeling and inventory requirements for TBAC.
    There is no evidence that TBAC is being used at levels that would 
cause concern for ozone formation. Additionally, the EPA believes these 
requirements, which are unique among all VOC-exempt compounds, are of 
limited utility because they do not provide sufficient information to 
judge the cumulative impacts of exempted compounds, and because the 
data have not been consistently collected and reported. Because these 
requirements are not addressing any of the concerns as they were 
intended, the EPA is removing the requirements for TBAC to relieve 
industry and states of the associated information collection burden.
    This final action removes recordkeeping, emissions reporting, 
photochemical dispersion modeling and inventory requirements related to 
the use of TBAC. This action does not affect the existing exclusion of 
TBAC from the regulatory definition of VOC for purposes of emission 
limits and control requirements.
    We note that removal of the recordkeeping and reporting 
requirements does not indicate that the EPA has reached final 
conclusions about all aspects of the health effects posed by the use of 
TBAC or its metabolite TBA. The EPA is currently awaiting completion of 
the IRIS assessment on the potential risks involved with TBA and its 
toxicity. If it becomes clear that action is warranted due to the 
health risks of direct exposure to TBA or TBAC, the EPA will consider 
the range of authorities at its disposal to mitigate these risks 
appropriately.

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 and was 
therefore not submitted to the Office of Management and Budget (OMB) 
for review.

[[Page 9342]]

B. Paperwork Reduction Act (PRA)

    This action does not impose an information collection burden under 
the PRA. It does not contain any new recordkeeping or reporting 
requirements. This action removes recordkeeping, emissions reporting, 
photochemical dispersion modeling and inventory requirements related to 
use of TBAC.

C. Regulatory Flexibility Act (RFA)

    After considering the economic impacts of the TBAC final rule on 
small entities, I certify that this action will not have a significant 
economic impact on a substantial number of small entities under the 
RFA. In making this determination, the impact of concern is any 
significant adverse economic impact on small entities. 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, has no net burden or otherwise has a positive economic effect 
on the small entities subject to the rule. This action removes 
recordkeeping, emissions reporting, photochemical dispersion modeling 
and inventory requirements related to use of TBAC. We have, therefore, 
concluded that this action will relieve regulatory burden for all 
directly regulated small entities.

D. Unfunded Mandates Reform Act (UMRA)

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

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. In fact, 
this should reduce the burden on states.

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

    This action does not have tribal implications, as specified in 
Executive Order 13175. This final action removes existing emission 
inventory reporting and other requirements that uniquely apply to TBAC 
among all VOC-exempt compounds. Thus, Executive Order 13175 does not 
apply to this action.

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

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. This action is not subject to 
Executive Order 13045 because the EPA does not believe the 
environmental health or safety risks addressed by this action present a 
disproportionate risk to children. This action removes recordkeeping, 
emissions reporting, photochemical dispersion modeling and inventory 
requirements related to use of TBAC. It does not affect the existing 
exclusion of TBAC from the regulatory definition of VOC for purposes of 
emission limits and control requirements.

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

    This action is not subject to Executive Order 13211, because it is 
not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

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

    The EPA believes the human health or environmental risk addressed 
by this action will not have disproportionately high and adverse human 
health or environmental effects on minority, low-income or indigenous 
populations. The EPA did not conduct an environmental analysis for this 
rule because the EPA does not believe that removing the unique 
reporting requirements will lead to substantial and predictable changes 
in the use of TBAC in and near particular communities.

K. Congressional Review Act (CRA)

    This action is subject to the CRA, and the EPA will submit a rule 
report to each House of the Congress and to the Comptroller General of 
the United States. This action is not a ``major rule'' as defined by 5 
U.S.C. 804(2).
