Partial Approval and Partial Disapproval of Air Quality State
Implementation Plans; Arizona; Infrastructure Requirements To Address
Interstate Transport for the 2008 Ozone NAAQS
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
partially approve and partially disapprove a State Implementation Plan
(SIP) revision submitted by the Arizona Department of Environmental
Quality on December 27, 2012, and supplemented on December 3, 2015, to
address the interstate transport requirements of Clean Air Act (CAA or
Act) section 110(a)(2)(D) with respect to the 2008 ozone
(O3) national ambient air quality standard (NAAQS). We are
proposing to approve the portion of the Arizona SIP pertaining to
significant contribution to
[[Page 15201]]
nonattainment or interference with maintenance in another state and
proposing to disapprove the portion of Arizona's SIP pertaining to
interstate transport visibility requirements. EPA's rationale for
proposing to partially approve and partially disapprove Arizona's
December 27, 2012 SIP revision and December 3, 2015 supplement is
described in this notice. EPA previously took two separate actions on
Arizona's December 27, 2012 submittal, on July 14, 2015 and August 10,
2015. We are taking comments on this proposal and plan to follow with a
final action no later than June 7, 2016.
DATES: Written comments must be received on or before April 21, 2016.
ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R09-
OAR-2015-0793 at http://www.regulations.gov, or via email to

I. Background
CAA sections 110(a)(1) and (2) require states to address basic SIP
requirements to implement, maintain and enforce the NAAQS no later than
three years after the promulgation of a new or revised standard.
Section 110(a)(2) outlines the specific requirements that each state is
required to address in this SIP submission that collectively constitute
the ``infrastructure'' of a state's air quality management program. SIP
submittals that address these requirements are referred to as
``infrastructure SIPs'' (I-SIP). In particular, CAA section
110(a)(2)(D)(i)(I) requires that each SIP for a new or revised NAAQS
contain adequate provisions to prohibit any source or other type of
emissions activity within the state from emitting air pollutants that
will ``contribute significantly to nonattainment'' (prong 1) or
``interfere with maintenance'' (prong 2) of the applicable air quality
standard in any other state. CAA section 110(a)(2)(D)(i)(II) requires
SIP provisions that prevent interference with measures required to be
included in the applicable implementation plan for any other State
under part C to prevent significant deterioration of air quality (prong
3) or to protect visibility (prong 4). This action addresses the
section 110(a)(2)(D)(i) requirements of prongs 1, 2 and 4 with respect
to Arizona's I-SIP submissions.
On March 27, 2008, EPA issued a revised NAAQS for ozone.\1\ This
action triggered a requirement for states to submit an I-SIP to address
the applicable requirements of section 110(a)(2) within three years of
issuance of the revised NAAQS.

---------------------------------------------------------------------------
On September 13, 2013, EPA issued ``Guidance on Infrastructure
State Implementation Plan (SIP) Elements under Clean Air Act Sections
110(a)(1) and 110(a)(2),'' which provides ``advice on the development
of infrastructure SIPs for the 2008 ozone NAAQS . . . as well as
infrastructure SIPs for new or revised NAAQS promulgated in the
future.'' \2\ EPA followed that guidance with an additional memo
specific to 110(a)(2)(D)(i)(I) (prongs 1 and 2) requirements for the
2008 O3 standard on January 22, 2015 entitled, ``Information
on the Interstate Transport ``Good Neighbor'' Provision for the 2008
Ozone NAAQS Under CAA Section 110(a)(2)(D)(i)(I)'' (2015 transport
memo).\3\ While this memo did not provide specific guidance to western
states on interstate transport, it did contain preliminary modeling
information for western states. This 2015 transport memo, following the
approach used in EPA's prior Cross-State Air Pollution Rule (CSAPR),\4\
provided data identifying ozone monitoring sites that were projected to
be in nonattainment or have maintenance problems for the 2008 ozone
NAAQS in 2018. Also, EPA provided the projected contribution estimates
from 2018 anthropogenic oxides of nitrogen (NOX) and
volatile organic compound (VOC) emissions in each state to ozone
concentrations at each of the projected sites.

On August 4, 2015, EPA published a Federal Register Notice
entitled, ``Notice of Availability of the Environmental Protection
Agency's Updated Ozone Transport Modeling Data for the 2008 Ozone
NAAQS.'' \5\ This Notice of Data Availability (NODA) is an update of
the preliminary air quality modeling data that was released January 22,
2015. This NODA provided data identifying ozone monitoring sites that
are projected to be nonattainment or have maintenance problems
(following the CSAPR approach) for the 2008 ozone NAAQS in 2017.\6\
Also, EPA provided the projected ozone contribution estimates from 2017
anthropogenic NOX and VOC emissions in each state to ozone
concentrations at each of the projected monitoring sites. The 2017
modeling released in the NODA was used to support EPA's proposed update
to CSAPR to address CAA section 110(a)(2)(D)(i)(I) requirements with
respect to the 2008 ozone NAAQS in the eastern U.S. (``CSAPR Update
Rule'').\7\ CSAPR and its predecessor transport rules, the
NOX SIP Call and CAIR, were designed to address the
collective contributions from the 37 states in the eastern U.S. and
ozone contribution information was not calculated to or from the 11
states in the western U.S. The proposed CSAPR Update Rule and the
supportive
[[Page 15202]]
modeling released in the NODA include data relevant to the West but did
not evaluate potential interstate transport impacts in 11 western
states, including Arizona. In this action, we are utilizing these data
to evaluate the state's submittals and any interstate transport
obligations under section 110(a)(2)(D)(i)(I).

II. State Submittals
On December 27, 2012, the Arizona Department of Environmental
Quality (ADEQ) submitted its 2008 ozone NAAQS I-SIP (2012 submittal).
This submittal briefly summarized the CAA requirements of sections
110(a)(2)(D)(i), 110(a)(2)(D)(ii), and EPA's I-SIP action for the
previous 1997 ozone NAAQS, but as to prongs 1, 2, and 4 did not
identify or address any potential interstate transport impacts between
Arizona and other states or interstate transport visibility
requirements for the 2008 ozone NAAQS. On December 3, 2015, ADEQ
submitted a supplement to the 2012 submittal addressing 110(a)(2)(D)(i)
prongs 1, 2, and 4.\11\ For the purposes of this action, we will refer
to the supplemental submittal as the ``2015 submittal.'' The 2015
submittal represents ADEQ's comprehensive analysis of ozone transport
from Arizona to surrounding states and addresses potential interstate
transport linkages between Arizona and the El Centro, CA and Los
Angeles, CA nonattainment receptors that were identified in the 2015
ozone transport memo and the 2015 NODA. The 2015 submittal also
addresses the requirements of prong 4 (interstate transport visibility
requirements).

Heidi Haggerty of ADEQ. ``AZ 2015 Ozone Transport I-SIP Submittal
Clarification.'' Sent December 9, 2015.
---------------------------------------------------------------------------
In the 2015 submittal, ADEQ summarizes the state's impact on
downwind states. While Arizona's impact on the El Centro and Los
Angeles monitors is in each case above 1%, Arizona impacts only one of
the seven projected nonattainment or maintenance receptors in the Los
Angeles area, and contributes less than 1% to all other maintenance and
nonattainment receptors. ADEQ further states that, ``In eastern states,
the EPA has chosen a 1% of the standard threshold as a significant
contribution. However, Arizona considers the southwest to be
different.'' The state goes on to say that, ``It is unclear at this
point what threshold is significant for southwestern states.'' EPA's
assessment of these statements is described in the next section. The
submittal also summarizes sources of VOCs and NOX statewide,
outlining the controls on anthropogenic emission sources with a focus
on efforts to reduce NOX through controls implemented via
Arizona's Regional Haze SIP and EPA's Regional Haze Federal
Implementation Plan (FIP) and current and future Maricopa County
stationary source controls in the Arizona SIP. For more information on
Arizona's source categories and emissions controls, please see the
technical support document (TSD) associated with today's proposed
rulemaking.
III. EPA's Assessment
110(a)(2)(D)(i)(I) Prong 1 and Prong 2
EPA proposes to approve Arizona's SIP submissions pertaining to CAA
section 110(a)(2)(D)(i)(I), prongs 1 and 2, with respect to the 2008
ozone NAAQS. As explained below, EPA's proposal is based on the state's
submission and EPA's analysis of several factors and available data.
To determine whether the CAA section 110(a)(2)(D)(i)(I), prongs 1
and 2 requirement is satisfied, EPA first must determine whether a
state's emissions will contribute significantly to nonattainment or
interfere with maintenance of a NAAQS in other states. If a state is
determined not to make such contribution or interfere with maintenance
of the NAAQS, then EPA can conclude that the state's SIP complies with
the requirements of section 110(a)(2)(D)(i)(I). In several prior
federal rulemakings interpreting section 110(a)(2)(D)(i)(I), EPA has
evaluated whether a state will significantly contribute to
nonattainment or interfere with maintenance of a NAAQS by first
identifying downwind receptors that are expected to have problems
attaining or maintaining the NAAQS.\12\ EPA has then determined which
upwind states contribute to these identified air quality problems in
amounts sufficient to warrant further evaluation to determine if the
state can make emission reductions to reduce its contribution. CSAPR
and the proposed CSAPR Update used a screening threshold (1% of the
NAAQS) to identify such contributing upwind states warranting further
review and analysis. EPA's NODA used air quality modeling to evaluate
contributions from upwind states to downward receptors. Applying the
methodology used in CSAPR, the NODA modeling information indicates that
emissions from Arizona contribute amounts exceeding the CSAPR 1%
threshold at two projected downwind nonattainment sites in El Centro,
California, and Los Angeles, California.\13\

\13\ Data file with 2017 Ozone Contributions. Included in docket
for: Notice of Availability of the Environmental Protection Agency's
Updated Ozone Transport Modeling Data for the 2008 Ozone National
Ambient Air Quality Standard (NAAQS), 80 FR 46271 (August 4, 2015).
---------------------------------------------------------------------------
EPA notes that it disagrees with ADEQ's contention that it is
unclear what screening threshold is significant for southwestern states
when addressing interstate transport contributions. EPA believes
contribution from an individual state equal to or above 1% of the NAAQS
could be considered significant where the collective contribution of
emissions from one or more upwind states is responsible for a
considerable portion of the downwind air quality problem regardless of
where the receptor is geographically located.\14\
---------------------------------------------------------------------------
\14\ EPA has previously noted there may be additional criteria
to evaluate regarding collective contribution of transported air
pollution at certain locations in the West. See footnotes 4 and 7.
---------------------------------------------------------------------------
Accordingly, although EPA's modeling indicates that emissions from
[[Page 15203]]
Arizona contribute above the 1% threshold to two projected downwind air
quality problems, EPA examined several factors to determine whether
Arizona should be considered to significantly contribute to
nonattainment or interfere with maintenance of the NAAQS at those
sites, including the air quality and contribution modeling, receptor
data, and the statewide measures reducing emissions of VOCs and
NOX. EPA notes that no single piece of information is by
itself dispositive of the issue for purposes of this analysis. Instead,
EPA has considered the total weight of all the evidence taken together
to evaluate whether Arizona significantly contributes to nonattainment
or interferes with maintenance of the 2008 ozone NAAQS in those areas.
One such factor that EPA considers relevant to determining the
nature of a projected receptor's interstate transport problem is the
magnitude of ozone attributable to transport from all upwind states
collectively contributing to the air quality problem. In CSAPR and the
CSAPR Update Rule, EPA used the 1% air quality threshold to identify
linkages between upwind states and downwind maintenance receptors.
States whose contributions to a specific receptor meet or exceed the
threshold were considered to be linked to that receptor. The linked
states' emissions (and available emission reductions) were then
analyzed further as a second step to EPA's contribution analysis.
States whose contributions to all receptors were below the 1% threshold
did not require further evaluation to address interstate transport and
we therefore found those states were determined to make insignificant
contributions to downwind air quality. Therefore, the states below the
threshold do not significantly contribute to nonattainment or interfere
with maintenance of the NAAQS in other states. EPA used the 1%
threshold in the East because prior analysis showed that, in general,
nonattainment problems result from a combined impact of relatively
small individual contributions from upwind states, along with
contributions from in-state sources. EPA has observed that a relatively
large portion of the air quality problem at most ozone nonattainment
and maintenance receptors in the East is the result of the collective
contribution from a number of upwind states.
Specifically, EPA found the total upwind states' contribution to
ozone concentration (from linked and unlinked states) based on modeling
for 2017 ranges from 17% to 67% to identified downwind air quality
problems in the East, with between 4 and 12 states each contributing
above 1% to the downwind air quality problem.15 16 Thus,
irrespective of the 1% air quality threshold in the East, EPA has found
that the collective contributions from upwind states represent a large
portion of the ozone concentrations at projected air quality problems.
Further, in the East, EPA found that the 1% threshold is appropriate to
capture a high percentage of the total pollution transport affecting
downwind receptors. By comparison, according to EPA's modeling, the
total upwind (linked or unlinked) states' contribution to ozone
concentration at the projected nonattainment sites in El Centro,
California and Los Angeles, California, is comparatively small, with
only one state contributing above 1% to the downwind air quality
problem.
---------------------------------------------------------------------------
\15\ The stated range is based on the highest nonattainment or
maintenance receptor in each area. All nonattainment and maintenance
receptors had upwind contributions of well over 17%, except for some
receptors in Dallas and Houston.
\16\ Memo to Docket from EPA, Air Quality Policy Division.
``Contribution Analysis of Receptors in the Updated CSAPR
Proposal.'' March 10, 2016.
---------------------------------------------------------------------------
Arizona is the only state that contributes greater than the 1%
threshold to the projected 2017 levels of the 2008 ozone NAAQS at the
El Centro receptor. The total contribution from all states to the El
Centro receptor is 4.4% of the total ozone concentration at this
receptor. Arizona is also the only state that contributes greater than
1% to the projected 2017 levels of the 2008 ozone NAAQS at the Los
Angeles receptor, and the total contribution from all states is 2.5% of
the ozone concentration at this receptor. EPA believes that a 4.4% and
2.5% cumulative ozone contribution from all upwind states is
negligible, particularly when compared to the relatively large
contributions from upwind states in the East or in certain other areas
of the West. For these reasons, EPA believes the emissions that result
in transported ozone from upwind states have limited impacts on the
projected air quality problems in El Centro, California and Los
Angeles, California, and therefore should not be treated as receptors
for purposes of determining the interstate transport obligations of
upwind states under section 110(a)(2)(D)(i)(I).
Additionally, EPA has evaluated the Arizona VOC and NOX
emissions inventory and emissions projections and agrees that emissions
will be decreasing over time. Given that emissions within the state are
expected to decrease over time due to regional haze measures, Federal
engine and fuel standards, and other Federal, State, and local
rules,\17\ EPA believes that the Arizona SIP contains adequate
provisions to ensure that air emissions in Arizona do not significantly
contribute to nonattainment or interfere with maintenance of the 2008
ozone NAAQS in California or any other state in the future.
---------------------------------------------------------------------------
\17\ See TSD for details on other emissions control measures.
---------------------------------------------------------------------------
The modeling data show that Arizona contributes either less than 1%
of the NAAQS to projected air quality problems in other states, or
where it contributes above 1% of the NAAQS to a projected downwind air
quality problem in California, EPA proposes to find, based on the
overall weight of evidence, that these particular receptors are not
significantly impacted by transported ozone from upwind states.
Emissions reductions from Arizona are not necessary to address
interstate transport because the total collective upwind state ozone
contribution to these receptors is relatively low compared to the air
quality problems typically addressed by the good neighbor provision.
Additionally, Arizona has demonstrated that both VOC and NOX
emissions are going down and will continue to go down. EPA therefore
believes that Arizona's contributions to downwind receptors in
California are considered insignificant. EPA proposes to find that
Arizona does not significantly contribute to nonattainment or interfere
with maintenance of the 2008 ozone NAAQS in other states.
110(a)(2)(D)(i)(II) Prong 4
EPA believes that ozone precursor emissions of NOX may
contribute to visibility impairment in Class I areas. EPA's 2013 I-SIP
guidance clarifies that a state can rely upon a fully EPA-approved
Regional Haze SIP to satisfy the requirements of this sub-element.
Arizona's Regional Haze SIP shows that sources in Arizona impact
visibility in Colorado (Great Sand Dunes National Monument, Mesa Verde
National Park, Black Canyon of the Gunnison National Park, La Garita
Wilderness, and Weminuche Wilderness), New Mexico (Bandelier National
Monument, San Pedro Parks Wilderness, Pecos Wilderness, Bosque del
Apache National Wildlife Reserve, and Gila Wilderness), and Utah (Zion
National Park, Bryce Canyon National Park, Capitol Reef National Park,
Canyonlands National Park, and Arches
[[Page 15204]]
National Park).\18\ Arizona's Regional Haze SIP is not fully approved
by EPA. Instead, Arizona's 2012 and 2015 submittals rely, in part, on
regulations imposed by FIPs to address visibility impairment in Class 1
Areas caused by NOX, SO2, and PM. These
regulations include emission limits on the following facilities:
Arizona Public Service Cholla Power Plant,\19\ Salt River Project
Coronado Generating Station,\20\ Freeport McMoran Miami Smelter,\21\
ASARCO Hayden Smelter,\22\ Sundt Generating Station Unit 4,\23\ and
Nelson Lime Plant Kilns 1 and 2.\24\ Emissions limits have been
incorporated into the state SIP, replacing a previous FIP, at AEPCO
Apache Station Units 1, 2, and 3.\25\

---------------------------------------------------------------------------
Because Arizona's 2012 and 2015 submittals rely in part on FIPs to
address interstate transport visibility requirements, they do not meet
the requirements of prong 4 for the 2008 ozone NAAQS. However, because
FIPs are already in place, no additional FIP obligation would be
triggered by a final disapproval of this portion of Arizona's
infrastructure SIP. EPA will continue to work with Arizona to
incorporate emission limits to address the requirements of the Regional
Haze Rule into the Arizona SIP. For further discussion of our analysis
of prong 4, please see the TSD associated with this proposal and in the
docket for today's rulemaking.
IV. Proposed Action
EPA is proposing to approve Arizona's SIP as meeting the interstate
transport requirements of CAA section 110(a)(2)(D)(i)(I) prongs 1 and 2
for the 2008 ozone NAAQS. EPA is proposing this approval based on the
overall weight of evidence from information and analysis provided by
Arizona, as well as the recent air quality modeling released in EPA's
August 4, 2015 NODA, and other data analysis that confirms that
emissions from Arizona will not contribute significantly to
nonattainment or interfere with maintenance of the 2008 ozone NAAQS in
California or any other state.
EPA is proposing to disapprove Arizona's SIP with respect to the
interstate transport requirements of CAA section 110(a)(2)(D)(i)(II)
prong 4 for the 2008 ozone NAAQS. Because Arizona's 2012 and 2015
submittals rely, in part, on FIPs to address interstate transport
visibility requirements, they do not meet the requirements of this
portion of CAA Sec. 110(a)(2)(D) for the 2008 ozone NAAQS. However,
because FIPs are already in place, no additional FIP obligation would
be triggered by a final disapproval of this portion of Arizona's
infrastructure SIP. EPA will continue to work with Arizona to
incorporate emission limits to address the requirements of the Regional
Haze Rule into the Arizona SIP.
V. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.
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.
B. Paperwork Reduction Act (PRA)
This action does not impose an information collection burden under
the PRA because this action does not impose additional requirements
beyond those imposed by state law.
C. Regulatory Flexibility Act (RFA)
I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. This
action will not impose any requirements on small entities beyond those
imposed by state law.
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. This action does not impose additional requirements
beyond those imposed by state law. Accordingly, no additional costs to
State, local, or tribal governments, or to the private sector, will
result from this action.
E. Executive Order 13132: Federalism
This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government.
F. Executive Order 13175: Coordination With Indian Tribal Governments
This action does not have tribal implications, as specified in
Executive Order 13175, because the SIP is not approved to apply on any
Indian reservation land or in any other area where the EPA or an Indian
tribe has demonstrated that a tribe has jurisdiction, and will not
impose substantial direct costs on tribal governments or preempt tribal
law. Thus, Executive Order 13175 does not apply to this action.
G. Executive Order 13045: Protection of Children From Environmental
Health Risks 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 it does not impose additional
requirements beyond those imposed by state law.
H. Executive Order 13211: Actions 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)
Section 12(d) of the NTTAA directs the EPA to use voluntary

be inconsistent with applicable law or otherwise impractical. The EPA
believes that this action is not subject to the requirements of section
12(d) of the NTTAA because application of those requirements would be
inconsistent with the CAA.
