ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[EPA-R09-OAR-2015-0187; FRL-9945-96-Region 9]
Limited Disapproval of Air Plan Revisions; Arizona; New Source
Review; PM2.5
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing a
limited disapproval of a revision to the Arizona Department of
Environmental Quality (ADEQ) portion of the Arizona State
Implementation Plan (SIP) under the Clean Air Act (CAA or Act). This
ADEQ-submitted SIP revision primarily was intended to serve as a
replacement of ADEQ's SIP-approved rules for the issuance of New Source
Review (NSR) permits for stationary sources, including but not limited
to the rules governing the review and permitting of major sources and
major modifications under the Act. This action concerns only the major
nonattainment NSR provisions in ADEQ's submittal as they pertain to the
Nogales and West Central Pinal nonattainment areas for particulate
matter with a diameter of 2.5 micrometers or less (PM2.5).
The EPA previously finalized a limited approval for these
PM2.5 nonattainment areas related to certain major
nonattainment NSR permitting requirements for PM2.5 under
the CAA, and is now also proposing a limited disapproval to set the
stage for remedying certain deficiencies related to these requirements.
DATES: Comments must arrive by June 1, 2016.

I. The State's Submittal
A. What did the State submit?
On July 28, 2011 and October 29, 2012, ADEQ submitted revisions to
the ADEQ portion of the Arizona SIP for EPA approval under the CAA. On
May 16, 2014, ADEQ supplemented the July 28, 2011 submittal. On
September 6, 2013, July 2, 2014, and February 16, 2015, ADEQ
supplemented the October 29, 2012 submittal. Collectively, these
submittals generally comprise ADEQ's current program for
preconstruction review and permitting of new or modified stationary
sources under ADEQ's jurisdiction in Arizona. On November 2, 2015, the
EPA finalized a limited approval and limited disapproval, and other
actions, for these submittals. See our final rule at 80 FR 67319 (Nov.
2, 2015) and proposed rule at 80 FR 14044 (Mar. 18, 2015). The EPA is
now taking further action related to these submittals. The specific
rules that were reviewed as part of these submittals and our previous
action, and which are the subject of this action, can be found in Table
1 of the preamble to our November 2, 2015 final rule (80 FR 67320).
The SIP submittals that are the subject of this action and our 2015
proposed and final rules, referred to herein as the
[[Page 26186]]
``NSR SIP submittal,'' represent a comprehensive revision to ADEQ's
preconstruction review and permitting program and were intended to
satisfy the requirements under both part C (prevention of significant
deterioration) (PSD) and part D (nonattainment new source review) of
title I of the Act for major sources as well as the general
preconstruction review requirements under section 110(a)(2)(C) of the
Act. The Act's preconstruction review and permitting programs are often
collectively referred to as ``New Source Review''.
Please see our previous proposed and final actions for the NSR SIP
submittal--Revisions to Air Plan; Arizona; Stationary Sources; New
Source Review--for a detailed description of the actions taken to date
related to these submittals, including the docket for these actions
(Docket ID No. EPA-R09-OAR-2015-0187 at www.regulations.gov) where
other supplementary materials are available.
On December 28, 2012, April 29, 2013, and December 2, 2014, ADEQ's
July 28, 2011, October 29, 2012, and July 2, 2014 submittals,
respectively, were deemed complete by operation of law to meet the
completeness criteria in 40 CFR part 51, appendix V, which must be met
before formal EPA review. Each of these submittals includes evidence of
public notice and adoption of the relevant ADEQ regulations.
B. What is the purpose of this proposed rule?
The purpose of this EPA rulemaking is solicit comment on whether
the major nonattainment NSR portion of ADEQ's NSR SIP submittal fully
meets the permitting requirements for PM2.5 precursors under
section 189(e) of the CAA. In the EPA's March 2015 proposed action on
ADEQ's NSR SIP Submittal, we explained that we were not evaluating at
that time whether the NSR SIP submittal would require additional
revisions related to PM2.5 to satisfy CAA section 189(e)
requirements, and we finalized our action accordingly in November 2015.
We are now proposing a limited disapproval of the major nonattainment
NSR portion of ADEQ's NSR SIP submittal for PM2.5 as it
pertains to the statutory requirements of section 189(e).
II. The EPA's Evaluation and Action
A. How is the EPA evaluating the submittal?
At this time the EPA is evaluating whether ADEQ's NSR SIP submittal
meets certain permitting requirements for PM2.5
nonattainment areas under title I, part D, subpart 4 of the CAA
(subpart 4). At the time of our 2015 action, we did not determine that
the submittal fully addressed section 189(e) in subpart 4, related to
NSR permitting requirements for PM2.5 for major stationary
sources in PM2.5 nonattainment areas, and instead finalized
a limited approval related to subpart 4 based on this issue. For
PM2.5 nonattainment areas, section 189(e) requires that the
control requirements applicable under plans in effect under part D of
the CAA for major stationary sources of PM2.5 also apply to
major stationary sources of PM2.5 precursors, except where
the Administrator determines that such sources do not contribute
significantly to PM2.5 levels which exceed the standards in
the area.
B. Does the submittal meet the evaluation criteria?
As explained further below, in order to meet the evaluation
criteria in CAA section 189(e) for PM2.5 as discussed above,
ADEQ's NSR SIP submittal would need to (1) require major stationary
sources of PM2.5 precursors (nitrogen oxides
(NOX), sulfur dioxide (SO2), volatile organic
compounds (VOC), and ammonia) in areas designated nonattainment for the
PM2.5 National Ambient Air Quality Standards (NAAQS) to meet
the same control requirements as those applicable to major stationary
sources of PM2.5, or (2) if not including such requirements
for any of these precursors, provide a demonstration that the
particular precursor does not contribute significantly to
PM2.5 levels that exceed the standard in the relevant
PM2.5 nonattainment area. As explained in our March 2015
proposed action on the ADEQ NSR SIP submittal, the rules in that
submittal regulate NOX and SO2 as
PM2.5 precursors (see 80 FR 14057). As a result, the only
remaining element for evaluation is whether the submittal appropriately
addresses VOC and ammonia as PM2.5 precursors.
1. Background
On January 4, 2013, the U.S. Court of Appeals for the District of
Columbia Circuit, in Natural Resources Defense Council (NRDC) v. EPA,
issued a decision that remanded the EPA's 2007 and 2008 rules
implementing the 1997 PM2.5 NAAQS. See 706 F.3d 428 (D.C.
Cir. 2013). The 2008 EPA implementation rule addressed by the court
decision, ``Implementation of New Source Review (NSR) Program for
Particulate Matter Less Than 2.5 Micrometers (PM2.5)'' (the
2008 NSR PM2.5 Rule),\1\ promulgated NSR requirements for
implementation of PM2.5 in both nonattainment areas (under
the nonattainment NSR program) and attainment/unclassifiable areas
(under the PSD program). The Court of Appeals found that the EPA had
erred in implementing the PM2.5 NAAQS in these rules for
nonattainment areas solely pursuant to the general implementation
provisions of subpart 1 of part D of title I of the CAA, rather than
pursuant to the additional implementation provisions specific to
particulate matter nonattainment areas in subpart 4 of part D of title
I. The Court of Appeals ordered the EPA to ``repromulgate these rules
pursuant to Subpart 4 consistent with this opinion.'' 706 F.3d at 437.
The EPA issued a proposed rule to promulgate new generally applicable
implementation regulations for the PM2.5 NAAQS in accordance
with the requirements of subpart 4 and the Court's remand decision, see
80 FR 15340 (March 23, 2015), but the EPA has not yet issued the final
implementation rule. In the interim, however, states and the EPA still
need to proceed with implementation of the PM2.5 NAAQS in a
timely and effective fashion in order to meet statutory obligations
under the CAA and to assure the protection of public health intended by
those NAAQS.
---------------------------------------------------------------------------
\1\ 73 FR 28321 (May 16, 2008).
---------------------------------------------------------------------------
2. ADEQ's NSR SIP Submittal for PM2.5 Nonattainment Areas
ADEQ's NSR SIP submittal generally includes requirements for the
PM2.5 nonattainment NSR program for major sources consistent
with the provisions promulgated in the EPA's 2008 NSR PM2.5
Rule. Specifically, ADEQ's NSR SIP submittal includes the
PM2.5 significant emission rates at R18-2-101(130),
regulation of certain PM2.5 precursors (SO2 and
NOX) at R18-2-101(130), the regulation of PM10
and PM2.5 condensable emissions at R18-2-101(122)(f), and
the emissions offset requirements at R18-2-403(A)(3). The EPA approved
these provisions into ADEQ's SIP as part of a limited approval and
limited disapproval, and other actions, on November 2, 2015 (80 FR
67319).
Although ADEQ's NSR SIP submittal does include regulation of major
sources of SO2 and NOX as PM2.5
precursors under the major source nonattainment NSR program, it does
not include rules regulating VOCs or ammonia in this manner. Nor does
the NSR SIP submittal include a demonstration showing that
[[Page 26187]]
the regulation of VOCs and ammonia is not necessary under section
189(e).
The evaluation of which precursors need to be controlled to achieve
a NAAQS in a particular nonattainment area is typically conducted in
the context of the state's preparing and the EPA's reviewing an area's
attainment plan SIP. In this case, there are two designated
PM2.5 nonattainment areas in Arizona, the Nogales (portion
of Santa Cruz County, AZ) and West Central Pinal (portion of Pinal
County, AZ) areas. Both are designated nonattainment for the 2006
annual PM2.5 NAAQS. However, on January 7, 2013 and
September 4, 2013, the EPA finalized determinations of attainment for
these areas, respectively (78 FR 887 and 78 FR 54394), which suspended
the requirement for the state to submit, among other things, an
attainment plan SIP for the areas.\2\ Accordingly, PM2.5
attainment plans for SIP approval are not before EPA Region 9 for these
areas, nor were they at the time of the EPA's proposed or final 2015
actions on the NSR SIP submittal. In 2015, as the EPA did not have
before it the state's analysis as to which precursors needed to be
controlled in these areas pursuant to section 189(e) of the Act, we
determined that we could not fully approve as complying with the Act a
nonattainment NSR SIP that addressed only a subset of the scientific
PM2.5 precursors recognized by the EPA. We determined that
while ADEQ's NSR SIP submittal may not contain all of the elements
necessary to satisfy the CAA requirements when evaluated under subpart
4, the major source nonattainment NSR portion of the submittal
represented a considerable strengthening of the previously approved
Arizona SIP, which did not previously address NSR permitting for
PM2.5 at all. Therefore, in our 2015 action, the EPA granted
limited approval to the PM2.5 major nonattainment NSR
provisions in ADEQ's NSR SIP submittal for the Nogales and West Central
Pinal PM2.5 nonattainment areas based on the subpart 4
requirements, and indicated that we would consider whether a limited
disapproval was appropriate pertaining to these requirements when the
EPA re-promulgated its PM2.5 regulations with respect to
major nonattainment NSR permitting in response to the Court of Appeals'
remand decision in the NRDC case.
---------------------------------------------------------------------------
\2\ Prior to the NRDC Court's decision, the EPA would not have
reviewed PM2.5 attainment plan submittals for compliance
with Section 189.
---------------------------------------------------------------------------
Although the EPA has not yet re-promulgated these PM2.5
regulations in response to the remand decision, the EPA is now
proposing to determine that ADEQ's NSR SIP submittal does not fully
satisfy the major nonattainment NSR requirements for PM2.5
under section 189(e) of the Act for the Nogales and West Central Pinal
PM2.5 nonattainment areas, based on our finding that the
submittal does not include rules regulating VOCs or ammonia as
PM2.5 precursors under the major source nonattainment NSR
program, nor does it include a demonstration showing that the
regulation of VOCs and ammonia is not necessary under section 189(e).
We find it is appropriate to take action now in order to proceed with
implementation of the major source nonattainment NSR program for the
PM2.5 NAAQS in a timely and effective fashion to address
statutory obligations under the CAA and to assure the protection of
public health as intended by the Act based on those NAAQS. Therefore,
we are proposing a limited disapproval of the major source
nonattainment NSR provisions in ADEQ's NSR SIP submittal for the
Nogales and West Central Pinal PM2.5 nonattainment areas
based on our finding that the submittal does not fully satisfy section
189(e) of the Act as it relates to PM2.5 precursors. To
address this limited disapproval, ADEQ must revise its major source
nonattainment NSR permitting program to include VOC and ammonia as
PM2.5 precursors, or provide a demonstration satisfying the
requirement in section 189(e) that a particular precursor does not
contribute significantly to PM2.5 levels that exceed the
standard in the Nogales and/or West Central Pinal PM2.5
nonattainment areas.
C. Proposed Action and Public Comment
Pursuant to Section 110(k) of the Act, and for the reasons provided
above, we are proposing a limited disapproval of the major source
nonattainment NSR provisions of ADEQ's NSR SIP submittal for the
Nogales and West Central Pinal PM2.5 nonattainment areas
under section 189(e) of the Act related to PM2.5 precursors.
The EPA is proposing this action because, although we found that the
NSR SIP submittal met most of the applicable NSR permitting
requirements for PM2.5 nonattainment areas, we have found
certain deficiencies that prevent full approval. The intended effect of
our limited disapproval action is to set the stage for remedying
deficiencies in these regulations in a timely fashion.
If finalized as proposed, our limited disapproval action will
trigger an obligation on the EPA to promulgate a Federal Implementation
Plan unless Arizona corrects the deficiencies that are the bases for
this limited disapproval, and the EPA approves the related plan
revisions, within two years of the final action. Additionally, the
offset sanction in CAA section 179(b)(2) would apply in the
nonattainment areas at issue 18 months after the effective date of a
final limited disapproval, and the highway funding sanctions in CAA
section 179(b)(1) would apply in these areas six months after the
offset sanction is imposed. However, neither sanction will be imposed
under the CAA if Arizona submits, and we approve, prior to the
implementation of the sanctions, SIP revisions that correct the
deficiencies that we identify in a final action. The EPA is working
with ADEQ to correct the deficiencies identified in this action in a
timely manner.
We will accept comments from the public on the proposed disapproval
for the next 30 days.
III. 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.
[[Page 26188]]
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
consensus standards in its regulatory activities unless to do so would
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.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Population
The EPA lacks the discretionary authority to address environmental
justice in this rulemaking.
