ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-RO5-OAR-2014-0657; FRL-9929-45-Region 5]


Approval and Promulgation of Air Quality Implementation Plans; 
Michigan; Infrastructure SIP Requirements for the 2008 Ozone, 2010 
NO2, 2010 SO2, and 2012 PM2.5 NAAQS; 
Michigan State Board Requirements

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve elements of state implementation plan (SIP) submissions from 
Michigan regarding the infrastructure requirements of section 110 of 
the Clean Air Act (CAA) for the 2008 ozone, 2010 nitrogen dioxide 
(NO2), 2010 sulfur dioxide (SO2), and 2012 fine 
particulate (PM2.5) National Ambient Air Quality Standards 
(NAAQS). The infrastructure requirements are designed to ensure that 
the structural components of each state's air quality management 
program are adequate to meet the state's responsibilities under the 
CAA. EPA is also proposing to approve a submission from Michigan 
addressing the state board requirements under section 128 of the CAA.

II. What is the background of these SIP submissions?

A. What state SIP submissions does this rulemaking address?

    This rulemaking addresses submissions from the Michigan Department 
of Environmental Management (MDEQ). The state submitted its 
infrastructure SIP for the 2008 ozone, 2010 NO2, 2010 
SO2, and 2012 PM2.5 NAAQS, as well as state board 
requirements under section 128 for incorporation into the SIP, on July 
10, 2014.

B. Why did the state make these SIP submissions?

    Under sections 110(a)(1) and (2) of the CAA, states are required to 
submit infrastructure SIPs to ensure that their SIPs provide for 
implementation, maintenance, and enforcement of the NAAQS, including 
the 2008 ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS. These submissions must contain any revisions 
needed for meeting the applicable SIP requirements of section 
110(a)(2), or certifications that their existing SIPs for the NAAQS 
already meet those requirements.
    EPA highlighted this statutory requirement in an October 2, 2007, 
guidance document entitled ``Guidance on SIP Elements Required Under 
Sections 110(a)(1) and (2) for the 1997 8-hour Ozone and 
PM2.5 National Ambient Air Quality Standards'' (2007 Memo) 
and has issued additional guidance documents, the most recent on 
September 13, 2013, ``Guidance on Infrastructure State Implementation 
Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and (2)'' 
(2013 Memo). The SIP submissions referenced in this rulemaking pertain 
to the applicable requirements of section 110(a)(1) and (2), and 
address the 2008 ozone, 2010 NO2, 2010 SO2, and 
2012 PM2.5 NAAQS. To the extent that the prevention of 
significant deterioration (PSD) program is non-NAAQS specific, a narrow 
evaluation of other NAAQS will be included in the appropriate sections.

C. What is the scope of this rulemaking?

    EPA is acting upon the SIP submissions from MDEQ that address the 
infrastructure requirements of CAA sections 110(a)(1) and 110(a)(2) for 
the 2008 ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS. The requirement for states to make a SIP 
submission of this type arises out of CAA section 110(a)(1). Pursuant 
to section 110(a)(1), states must make SIP submissions ``within 3 years 
(or such shorter period as the Administrator may prescribe) after the 
promulgation of a national primary ambient air quality standard (or any 
revision thereof),'' and these SIP submissions are to provide for the 
``implementation, maintenance, and enforcement'' of such NAAQS. The 
statute directly imposes on states the duty to make these SIP 
submissions, and the requirement to make the submissions is not 
conditioned upon

[[Page 36308]]

EPA's taking any action other than promulgating a new or revised NAAQS. 
Section 110(a)(2) includes a list of specific elements that ``[e]ach 
such plan'' submission must address.
    EPA has historically referred to these SIP submissions made for the 
purpose of satisfying the requirements of CAA section 110(a)(1) and 
110(a)(2) as ``infrastructure SIP'' submissions. Although the term 
``infrastructure SIP'' does not appear in the CAA, EPA uses the term to 
distinguish this particular type of SIP submission from submissions 
that are intended to satisfy other SIP requirements under the CAA, such 
as ``nonattainment SIP'' or ``attainment plan SIP'' submissions to 
address the nonattainment planning requirements of part D of title I of 
the CAA, ``regional haze SIP'' submissions required by EPA rule to 
address the visibility protection requirements of CAA section 169A, and 
nonattainment new source review (NNSR) permit program submissions to 
address the permit requirements of CAA, title I, part D.
    This rulemaking will not cover three substantive areas that are not 
integral to acting on a state's infrastructure SIP submission: (i) 
Existing provisions related to excess emissions during periods of 
start-up, shutdown, or malfunction at sources, that may be contrary to 
the CAA and EPA's policies addressing such excess emissions (SSM); (ii) 
existing provisions related to ``director's variance'' or ``director's 
discretion'' that purport to permit revisions to SIP-approved emissions 
limits with limited public process or without requiring further 
approval by EPA, that may be contrary to the CAA (director's 
discretion); and, (iii) existing provisions for PSD programs that may 
be inconsistent with current requirements of EPA's ``Final New Source 
Review (NSR) Improvement Rule,'' 67 FR 80186 (December 31, 2002), as 
amended by 72 FR 32526 (June 13, 2007) (NSR Reform). Instead, EPA has 
the authority to address each one of these substantive areas in 
separate rulemakings. A detailed history, interpretation, and rationale 
as they relate to infrastructure SIP requirements can be found in EPA's 
May 13, 2014, proposed rule entitled, ``Infrastructure SIP Requirements 
for the 2008 Lead NAAQS'' in the section, ``What is the scope of this 
rulemaking?'' (see 79 FR 27241 at 27242-27245).

III. What guidance is EPA using to evaluate these SIP submissions?

    EPA's guidance for these infrastructure SIP submissions is embodied 
in the 2007 Memo. Specifically, attachment A of that memorandum 
(Required Section 110 SIP Elements) identifies the statutory elements 
that states need to submit in order to satisfy the requirements for an 
infrastructure SIP submission. EPA issued additional guidance 
documents, the most recent being the 2013 Memo, which further clarifies 
aspects of infrastructure SIPs that are not NAAQS specific.

IV. What is the result of EPA's review of these SIP submissions?

    As noted in the 2013 Memo, pursuant to section 110(a), states must 
provide reasonable notice and opportunity for public hearing for all 
infrastructure SIP submissions. MDEQ provided the opportunity for 
public comment for these submittals that ended on May 7, 2014. 
Additionally, MDEQ provided an opportunity for a public hearing. The 
state received comments and responded to them. EPA is also soliciting 
comment on our evaluation of the state's infrastructure SIP submission 
in this notice of proposed rulemaking. MDEQ provided detailed synopses 
of how various components of its SIP meet each of the requirements in 
section 110(a)(2) for the 2008 ozone, 2010 NO2, 2010 
SO2, and 2012 PM2.5 NAAQS, as applicable. The 
following review evaluates the state's submissions.

A. Section 110(a)(2)(A)--Emission Limits and Other Control Measures

    This section requires SIPs to include enforceable emission limits 
and other control measures, means or techniques, schedules for 
compliance, and other related matters. EPA has long interpreted 
emission limits and control measures for attaining the standards as 
being due when nonattainment planning requirements are due.\1\ In the 
context of an infrastructure SIP, EPA is not evaluating the existing 
SIP provisions for this purpose. Instead, EPA is only evaluating 
whether the state's SIP has basic structural provisions for the 
implementation of the NAAQS.
---------------------------------------------------------------------------

    \1\ See, e.g., EPA's final rule on ``National Ambient Air 
Quality Standards for Lead.'' 73 FR 66964 at 67034.
---------------------------------------------------------------------------

    The Michigan Natural Resources and Environmental Protection Act, 
1994 PA 451, as amended (Act 451), sections 324.5503 and 324.5512, 
provide the Director of MDEQ with the authority to regulate the 
discharge of air pollutants, and to promulgate rules to establish 
standards for emissions for ambient air quality and for emissions. To 
maintain the 2008 ozone NAAQS, Michigan implements controls and 
emission limits for nitrogen oxide (NOX), a precursor of 
ozone, in Michigan Administrative Code sections R 336.1801 through R 
336.1834; and controls and emission limits for volatile organic 
compounds (VOC), also a precursor of ozone, in sections R 336.1601 
through R 336.1661 and R 336.1701 through R 336.1710. The 
NOX controls in sections R 336.1801 through R 336.1834 also 
help to maintain the 2010 NO2 NAAQS. To maintain the 2010 
SO2 NAAQS, Michigan implements SO2 controls and 
emission limits in sections R 336.1401 through R 336.1420. To maintain 
the 2012 PM2.5 NAAQS, Michigan implements controls and 
emission limits for particulate matter sources in sections R 336.1301 
through R 336.1374. EPA proposes that Michigan has met the 
infrastructure SIP requirements of section 110(a)(2)(A) with respect to 
the 2008 ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS.
    As previously noted, EPA is not proposing to approve or disapprove 
any existing state provisions or rules related to SSM or director's 
discretion in the context of section 110(a)(2)(A).

B. Section 110(a)(2)(B)--Ambient Air Quality Monitoring/Data System

    This section requires SIPs to include provisions to provide for 
establishing and operating ambient air quality monitors, collecting and 
analyzing ambient air quality data, and making these data available to 
EPA upon request. This review of the annual monitoring plan includes 
EPA's determination that the state: (i) Monitors air quality at 
appropriate locations throughout the state using EPA-approved Federal 
Reference Methods or Federal Equivalent Method monitors; (ii) submits 
data to EPA's Air Quality System (AQS) in a timely manner; and, (iii) 
provides EPA Regional Offices with prior notification of any planned 
changes to monitoring sites or the network plan.
    MDEQ's authority to promulgate rules to establish ambient air 
quality standard are found in Michigan Compiled laws (MCL) 324.5503 and 
MCL 324.5512. MDEQ continues to operate an air monitoring network; EPA 
approved the state's 2015 Annual Air Monitoring Network Plan on October 
31, 2014, including the plan for ozone, NO2, SO2, 
and PM2.5. MDEQ enters air monitoring data into AQS, and the 
state provides EPA with prior notification when changes to its 
monitoring network or plan are being considered. EPA proposes that 
Michigan has met the infrastructure SIP requirements of section 
110(a)(2)(B) with respect to the

[[Page 36309]]

2008 ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS.

C. Section 110(a)(2)(C)--Program for Enforcement of Control Measures; 
PSD

    States are required to include a program providing for enforcement 
of all SIP measures and the regulation of construction of new or 
modified stationary sources to meet NSR requirements under PSD and NNSR 
programs. Part C of the CAA (sections 160-169B) addresses PSD, while 
part D of the CAA (sections 171-193) addresses NNSR requirements.
    The evaluation of each state's submission addressing the 
infrastructure SIP requirements of section 110(a)(2)(C) covers: (i) 
Enforcement of SIP measures; (ii) PSD provisions that explicitly 
identify NOX as a precursor to ozone in the PSD program; 
(iii) identification of precursors to PM2.5 and 
identification of PM2.5 and PM10 \2\ condensables 
in the PSD program; (iv) PM2.5 increments in the PSD 
program; and, (v) greenhouse gas (GHG) permitting and the ``Tailoring 
Rule.'' \3\
---------------------------------------------------------------------------

    \2\ PM10 refers to particles with diameters between 
2.5 and 10 microns, oftentimes referred to as ``coarse'' particles.
    \3\ In EPA's April 28, 2011, proposed rulemaking for 
infrastructure SIPS for the 1997 ozone and PM2.5 NAAQS, 
we stated that each state's PSD program must meet applicable 
requirements for evaluation of all regulated NSR pollutants in PSD 
permits (see 76 FR 23757 at 23760). This view was reiterated in 
EPA's August 2, 2012, proposed rulemaking for infrastructure SIPs 
for the 2006 PM2.5 NAAQS (see 77 FR 45992 at 45998). In 
other words, if a state lacks provisions needed to adequately 
address NOX as a precursor to ozone, PM2.5 
precursors, PM2.5 and PM10 condensables, 
PM2.5 increments, or the federal GHG permitting 
thresholds, the provisions of section 110(a)(2)(C) requiring a 
suitable PSD permitting program must be considered not to be met 
irrespective of the NAAQS that triggered the requirement to submit 
an infrastructure SIP, including the 2010 NO2 NAAQS.
---------------------------------------------------------------------------

Sub-Element 1: Enforcement of SIP Measures
    MDEQ maintains an enforcement program to ensure compliance with SIP 
requirements. Part 55 of Act 451, MCL 324.5501 through 324.5542, gives 
MDEQ the authority to enforce emission limits and other control 
measures in rules, permits, and orders. In addition, MCL 324.5530 
authorizes the Michigan Attorney General to commence a civil service 
action for appropriate relief for violations of or failure to comply 
with Part 55 of Act 451. The Clean Corporate Citizen Program is 
authorized through MCL 324.1401 through 324.1429. EPA proposes that 
Michigan has met the enforcement of SIP measures requirements of 
section 110(a)(2)(C) with respect to the 2008 ozone, 2010 
NO2, 2010 SO2, and 2012 PM2.5 NAAQS.
Sub-Element 2: PSD Provisions That Explicitly Identify NOX 
as a Precursor to Ozone in the PSD Program
    EPA's ``Final Rule to Implement the 8-Hour Ozone National Ambient 
Air Quality Standard--Phase 2; Final Rule to Implement Certain Aspects 
of the 1990 Amendments Relating to New Source Review and Prevention of 
Significant Deterioration as They Apply in Carbon Monoxide, Particulate 
Matter, and Ozone NAAQS; Final Rule for Reformulated Gasoline'' (Phase 
2 Rule) was published on November 29, 2005 (see 70 FR 71612). Among 
other requirements, the Phase 2 Rule obligated states to revise their 
PSD programs to explicitly identify NOX as a precursor to 
ozone (70 FR 71612 at 71679, 71699-71700). This requirement was 
codified in 40 CFR 51.166.
    The Phase 2 Rule required that states submit SIP revisions 
incorporating the requirements of the rule, including those identifying 
NOX as a precursor to ozone, by June 15, 2007 (see 70 FR 
71612 at 71683, November 29, 2005).
    EPA approved revisions to Michigan's PSD SIP reflecting these 
requirements on April 4, 2014 (see 79 FR 18802), and therefore proposes 
that Michigan has met the set of infrastructure SIP requirements of 
section 110(a)(2)(C) with respect to the 2008 ozone, 2010 
NO2, 2010 SO2, and 2012 PM2.5 NAAQS.
Sub-Element 3: Identification of Precursors to PM2.5 and the 
Identification of PM2.5 and PM10 Condensables in 
the PSD Program
    On May 16, 2008 (see 73 FR 28321), EPA issued the Final Rule on the 
``Implementation of the New Source Review (NSR) Program for Particulate 
Matter Less than 2.5 Micrometers (PM2.5)'' (2008 NSR Rule). 
The 2008 NSR Rule finalized several new requirements for SIPs to 
address sources that emit direct PM2.5 and other pollutants 
that contribute to secondary PM2.5 formation. One of these 
requirements is for NSR permits to address pollutants responsible for 
the secondary formation of PM2.5, otherwise known as 
precursors. In the 2008 rule, EPA identified precursors to 
PM2.5 for the PSD program to be SO2 and 
NOX (unless the state demonstrates to the Administrator's 
satisfaction or EPA demonstrates that NOX emissions in an 
area are not a significant contributor to that area's ambient 
PM2.5 concentrations). The 2008 NSR Rule also specifies that 
VOCs are not considered to be precursors to PM2.5 in the PSD 
program unless the state demonstrates to the Administrator's 
satisfaction or EPA demonstrates that emissions of VOCs in an area are 
significant contributors to that area's ambient PM2.5 
concentrations.
    The explicit references to SO2, NOX, and VOCs 
as they pertain to secondary PM2.5 formation are codified at 
40 CFR 51.166(b)(49)(i)(b) and 40 CFR 52.21(b)(50)(i)(b). As part of 
identifying pollutants that are precursors to PM2.5, the 
2008 NSR Rule also required states to revise the definition of 
``significant'' as it relates to a net emissions increase or the 
potential of a source to emit pollutants. Specifically, 40 CFR 
51.166(b)(23)(i) and 40 CFR 52.21(b)(23)(i) define ``significant'' for 
PM2.5 to mean the following emissions rates: 10 tons per 
year (tpy) of direct PM2.5; 40 tpy of SO2; and 40 
tpy of NOX (unless the state demonstrates to the 
Administrator's satisfaction or EPA demonstrates that NOX 
emissions in an area are not a significant contributor to that area's 
ambient PM2.5 concentrations). The deadline for states to 
submit SIP revisions to their PSD programs incorporating these changes 
was May 16, 2011 (see 73 FR 28321 at 28341).\4\
---------------------------------------------------------------------------

    \4\ EPA notes that on January 4, 2013, the U.S. Court of Appeals 
for the DC Circuit, in Natural Resources Defense Council v. EPA, 706 
F.3d 428 (D.C. Cir.), held that EPA should have issued the 2008 NSR 
Rule in accordance with the CAA's requirements for PM10 
nonattainment areas (Title I, Part D, subpart 4), and not the 
general requirements for nonattainment areas under subpart 1. As the 
subpart 4 provisions apply only to nonattainment areas, EPA does not 
consider the portions of the 2008 rule that address requirements for 
PM2.5 attainment and unclassifiable areas to be affected 
by the Court's opinion. Moreover, EPA does not anticipate the need 
to revise any PSD requirements promulgated by the 2008 NSR Rule in 
order to comply with the Court's decision. Accordingly, EPA's 
approval of Michigan's infrastructure SIP as to elements (C), 
(D)(i)(II), or (J) with respect to the PSD requirements promulgated 
by the 2008 implementation rule does not conflict with the court's 
opinion.
    The Court's decision with respect to the nonattainment NSR 
requirements promulgated by the 2008 implementation rule also does 
not affect EPA's action on the present infrastructure action. EPA 
interprets the CAA to exclude nonattainment area requirements, 
including requirements associated with a nonattainment NSR program, 
from infrastructure SIP submissions due three years after adoption 
or revision of a NAAQS. Instead, these elements are typically 
referred to as nonattainment SIP or attainment plan elements, which 
would be due by the dates statutorily prescribed under subparts 2 
through 5 under part D, extending as far as 10 years following 
designations for some elements.
---------------------------------------------------------------------------

    The 2008 NSR Rule did not require states to immediately account for 
gases that could condense to form particulate matter, known as 
condensables, in PM2.5 and PM10 emission limits 
in NSR permits. Instead, EPA determined that states had to account for 
PM2.5 and PM10 condensables for applicability 
determinations and in establishing emissions limitations for 
PM2.5 and

[[Page 36310]]

PM10 in PSD permits beginning on or after January 1, 2011. 
This requirement is codified in 40 CFR 51.166(b)(49)(i)(a) and 40 CFR 
52.21(b)(50)(i)(a). Revisions to states' PSD programs incorporating the 
inclusion of condensables were required be submitted to EPA by May 16, 
2011 (see 73 FR 28321 at 28341).
    EPA approved revisions to Michigan's PSD SIP reflecting these 
requirements on April 4, 2014 (see 79 FR 18802), and therefore proposes 
that Michigan has met this set of infrastructure SIP requirements of 
section 110(a)(2)(C) with respect to the 2008 ozone, 2010 
NO2, 2010 SO2, and 2012 PM2.5 NAAQS.
Sub-Element 4: PM2.5 Increments in the PSD Program
    On October 20, 2010, EPA issued the final rule on the ``Prevention 
of Significant Deterioration (PSD) for Particulate Matter Less Than 2.5 
Micrometers (PM2.5)--Increments, Significant Impact Levels 
(SILs) and Significant Monitoring Concentration (SMC)'' (2010 NSR 
Rule). This rule established several components for making PSD 
permitting determinations for PM2.5, including a system of 
``increments'' which is the mechanism used to estimate significant 
deterioration of ambient air quality for a pollutant. These increments 
are codified in 40 CFR 51.166(c) and 40 CFR 52.21(c), and are included 
in the table below.

    The 2010 NSR Rule also established a new ``major source baseline 
date'' for PM2.5 as October 20, 2010, and a new trigger date 
for PM2.5 as October 20, 2011. These revisions are codified 
in 40 CFR 51.166(b)(14)(i)(c) and (b)(14)(ii)(c), and 40 CFR 
52.21(b)(14)(i)(c) and (b)(14)(ii)(c). Lastly, the 2010 NSR Rule 
revised the definition of ``baseline area'' to include a level of 
significance of 0.3 micrograms per cubic meter, annual average, for 
PM2.5. This change is codified in 40 CFR 51.166(b)(15)(i) 
and 40 CFR 52.21(b)(15)(i).
    On April 4, 2014 (79 FR 18802), EPA finalized approval of the 
applicable infrastructure SIP PSD revisions; therefore, we are 
proposing that Michigan has met this set of infrastructure SIP 
requirements of section 110(a)(2)(C) with respect to the 2008 ozone, 
2010 NO2, 2010 SO2, and 2012 PM2.5 
NAAQS.
Sub-Element 5: GHG Permitting and the ``Tailoring Rule''
    With respect to Elements C and J, EPA interprets the CAA to require 
each state to make an infrastructure SIP submission for a new or 
revised NAAQS that demonstrates that the air agency has a complete PSD 
permitting program meeting the current requirements for all regulated 
NSR pollutants. The requirements of Element D(i)(II) may also be 
satisfied by demonstrating the air agency has a complete PSD permitting 
program correctly addressing all regulated NSR pollutants. Michigan has 
shown that it currently has a PSD program in place that covers all 
regulated NSR pollutants, including GHGs.
    On June 23, 2014, the United States Supreme Court issued a decision 
addressing the application of PSD permitting requirements to GHG 
emissions. Utility Air Regulatory Group v. Environmental Protection 
Agency, 134 S.Ct. 2427. The Supreme Court said that the EPA may not 
treat GHGs as an air pollutant for purposes of determining whether a 
source is a major source required to obtain a PSD permit. The Court 
also said that the EPA could continue to require that PSD permits, 
otherwise required based on emissions of pollutants other than GHGs, 
contain limitations on GHG emissions based on the application of Best 
Available Control Technology (BACT).
    In order to act consistently with its understanding of the Court's 
decision pending further judicial action to effectuate the decision, 
the EPA is not continuing to apply EPA regulations that would require 
that SIPs include permitting requirements that the Supreme Court found 
impermissible. Specifically, EPA is not applying the requirement that a 
state's SIP-approved PSD program require that sources obtain PSD 
permits when GHGs are the only pollutant (i) that the source emits or 
has the potential to emit above the major source thresholds, or (ii) 
for which there is a significant emissions increase and a significant 
net emissions increase from a modification (e.g. 40 CFR 
51.166(b)(48)(v)).
    EPA anticipates a need to revise Federal PSD rules in light of the 
Supreme Court opinion. In addition, EPA anticipates that many states 
will revise their existing SIP-approved PSD programs in light of the 
Supreme Court's decision. The timing and content of subsequent EPA 
actions with respect to the EPA regulations and state PSD program 
approvals are expected to be informed by additional legal process 
before the United States Court of Appeals for the District of Columbia 
Circuit. At this juncture, EPA is not expecting states to have revised 
their PSD programs for purposes of infrastructure SIP submissions and 
is only evaluating such submissions to assure that the state's program 
correctly addresses GHGs consistent with the Supreme Court's decision.
    At present, EPA is proposing that Michigan's SIP is sufficient to 
satisfy Elements C, D(i)(II), and J with respect to GHGs because the 
PSD permitting program previously approved by EPA into the SIP 
continues to require that PSD permits (otherwise required based on 
emissions of pollutants other than GHGs) contain limitations on GHG 
emissions based on the application of BACT. Although the approved 
Michigan PSD permitting program may currently contain provisions that 
are no longer necessary in light of the Supreme Court decision, this 
does not render the infrastructure SIP submission inadequate to satisfy 
Elements C, (D)(i)(II), and J. The SIP contains the necessary PSD 
requirements at this time, and the application of those requirements is 
not impeded by the presence of other previously-approved provisions 
regarding the permitting of sources of GHGs that EPA does not consider 
necessary at this time in light of the Supreme Court decision.
    For the purposes of the 2008 ozone, 2010 NO2, 2010 
SO2, and 2012 PM2.5 NAAQS infrastructure SIPs, 
EPA reiterates that NSR Reform regulations are not within the scope of 
these actions. Therefore, we are not taking action on existing NSR 
Reform regulations for Michigan. EPA approved Michigan's minor NSR 
program on May 6, 1980 (see 45 FR 29790); and since that date, MDEQ and 
EPA have relied on the existing minor NSR program to ensure that new 
and modified sources not captured by the major NSR permitting programs 
do not interfere with attainment and maintenance of the 2008 ozone, 
2010 NO2, 2010 SO2, and 2012 PM2.5 
NAAQS.
    Certain sub-elements in this section overlap with elements of 
section 110(a)(2)(D)(i), section 110(a)(2)(E) and section 110(a)(2)(J). 
These links will be discussed in the appropriate areas below.

D. Section 110(a)(2)(D)--Interstate Transport

    Section 110(a)(2)(D)(i)(I) requires SIPs to include provisions 
prohibiting any source or other type of emissions activity in one state 
from contributing

[[Page 36311]]

significantly to nonattainment, or interfering with maintenance, of the 
NAAQS in another state.
    On February 17, 2012, EPA promulgated designations for the 2010 
NO2 NAAQS, stating for the entire country that, ``The EPA is 
designating areas as ``unclassifiable/attainment'' to mean that 
available information does not indicate that the air quality in these 
areas exceeds the 2010 NO2 NAAQS'' (see 77 FR 9532). For 
comparison purposes, EPA examined the design values \5\ from 
NO2 monitors in Michigan and surrounding states. The highest 
design value based on data collected between 2011 and 2013 was 44 ppb 
at a monitor in Detroit, MI, compared to the standard which is 100 ppb 
for the 2010 NO2 NAAQS. Additionally, Michigan has SIP 
approved rules that limit NOX emissions, including rules in 
Michigan Administrative Code sections R 336.1801 through R 336.1834. 
EPA believes that, in conjunction with the continued implementation of 
the state's SIP-approved PSD and NNSR regulations, these low monitored 
values of NO2 will continue in and around Michigan. In other 
words, the NO2 emissions from Michigan are not expected to 
cause or contribute to a violation of the 2010 NO2 NAAQS in 
another state, and these emissions are not likely to interfere with the 
maintenance of the 2010 NO2 NAAQS in another state. 
Therefore, EPA proposes that Michigan has met transport prongs 1 and 2 
related to section 110(a)(2)(D)(i)(I) for the 2010 NO2 
NAAQS. Michigan, as noted in its July 11, 2014, clarification letter, 
did not make submittals pertaining to section 110(a)(2)(D)(i)(I) for 
the 2008 ozone, 2010 SO2, and 2012 PM2.5 NAAQS.
---------------------------------------------------------------------------

    \5\ The level of the 2010 NO2 NAAQS for is 100 parts 
per billion (ppb) and the form is the 3-year average of the annual 
98th percentile of the daily 1-hour maximum. For the most recent 
design values, see http://www.epa.gov/airtrends/values.html.
---------------------------------------------------------------------------

    Section 110(a)(2)(D)(i)(II) requires that SIPs include provisions 
prohibiting any source or other type of emissions activity in one state 
from interfering with measures required to prevent significant 
deterioration of air quality or to protect visibility in another state.
    EPA notes that Michigan's satisfaction of the applicable 
infrastructure SIP PSD requirements for the 2008 ozone, 2010 
NO2, 2010 SO2, and 2012 PM2.5 NAAQS 
have been detailed in the section addressing section 110(a)(2)(C). EPA 
further notes that the proposed actions in that section related to PSD 
are consistent with the proposed actions related to PSD for section 
110(a)(2)(D)(i)(II), and they are reiterated below.
    EPA has previously approved revisions to Michigan's SIP that meet 
certain requirements obligated by the Phase 2 Rule and the 2008 NSR 
Rule. These revisions included provisions that: Explicitly identify 
NOX as a precursor to ozone, explicitly identify 
SO2 and NOX as precursors to PM2.5, 
and regulate condensable PM2.5 and PM10 in 
applicability determinations and establishing emissions limits. EPA has 
also previously approved revisions to Michigan's SIP that incorporate 
the PM2.5 increments and the associated implementation 
regulations including the major source baseline date, trigger date, and 
level of significance for PM2.5 per the 2010 NSR Rule. EPA 
is proposing that Michigan's SIP contains provisions that adequately 
address the 2008 ozone, 2010 NO2, 2010 SO2, and 
2012 PM2.5 NAAQS.
    States also have an obligation to ensure that sources located in 
nonattainment areas do not interfere with a neighboring state's PSD 
program. One way that this requirement can be satisfied is through an 
NNSR program consistent with the CAA that addresses any pollutants for 
which there is a designated nonattainment area within the state.
    Michigan's EPA-approved NNSR regulations found in Part 2 of the 
SIP, specifically in Michigan Administrative Code sections R 336.1220 
and R 336.1221, are consistent with 40 CFR 51.165, or 40 CFR part 51, 
appendix S. Therefore, EPA proposes that Michigan has met all of the 
applicable PSD requirements for the 2008 ozone, 2010 NO2, 
2010 SO2, and 2012 PM2.5 NAAQS for transport 
prong 3 related to section 110(a)(2)(D)(i)(II).
    With regard to the applicable requirements for visibility 
protection of section 110(a)(2)(D)(i)(II), states are subject to 
visibility and regional haze program requirements under part C of the 
CAA (which includes sections 169A and 169B). The 2013 Memo states that 
these requirements can be satisfied by an approved SIP addressing 
reasonably attributable visibility impairment, if required, or an 
approved SIP addressing regional haze.
    In today's rulemaking, EPA is not proposing to approve or 
disapprove Michigan's satisfaction of the visibility protection 
requirements of section 110(a)(2)(D)(i)(II), transport prong 4, for the 
2008 ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS. Instead, EPA will evaluate Michigan's 
compliance with these requirements in a separate rulemaking.\6\
---------------------------------------------------------------------------

    \6\ Michigan has an approved regional haze plan for most non-
EGUs. Michigan's plan for EGUs relied on the Clean Air Interstate 
Rule that has been recently superseded by the Cross State Air 
Pollution Rule to which Michigan EGU sources are also subject.
---------------------------------------------------------------------------

    Section 110(a)(2)(D)(ii) requires that each SIP contains adequate 
provisions requiring compliance with the applicable requirements of 
sections 126 and 115 (relating to interstate and international 
pollution abatement, respectively).
    Section 126(a) requires new or modified sources to notify 
neighboring states of potential impacts from the source. The statute 
does not specify the method by which the source should provide the 
notification. States with SIP-approved PSD programs must have a 
provision requiring such notification by new or modified sources. A 
lack of such a requirement in state rules would be grounds for 
disapproval of this element.
    Michigan has provisions in its EPA-approved PSD program in Michigan 
Administrative Code section R 336.2817 requiring new or modified 
sources to notify neighboring states of potential negative air quality 
impacts, and has referenced this program as having adequate provisions 
to meet the requirements of section 126(a). EPA is proposing that 
Michigan has met the infrastructure SIP requirements of section 126(a). 
Michigan does not have any obligations under any other subsection of 
section 126, nor does it have any pending obligations under section 
115. EPA, therefore, is proposing that Michigan has met all applicable 
infrastructure SIP requirements of section 110(a)(2)(D)(ii) for the 
2008 ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS.

E. Section 110(a)(2)(E)--Adequate Resources

    This section requires each state to provide for adequate personnel, 
funding, and legal authority under state law to carry out its SIP, and 
related issues. Section 110(a)(2)(E)(ii) also requires each state to 
comply with the requirements respecting state boards under section 128.
Sub-Element 1: Adequate Personnel, Funding, and Legal Authority Under 
State Law To Carry Out Its SIP, and Related Issues
    MDEQ's SIP program is funded through 105 and 103 grants and 
matching funds from the state's General Fund. As discussed in earlier 
sections, MDEQ has the legal authority to carry

[[Page 36312]]

out the Michigan SIP under Act 451 and the Executive Reorganization 
Order 2011-1. Michigan's PSD regulations provide adequate resources to 
permit GHG sources. EPA proposes that Michigan has met the 
infrastructure SIP requirements of this portion of section 110(a)(2)(E) 
with respect to the 2008 ozone, 2010 NO2, 2010 
SO2, and 2012 PM2.5 NAAQS.
Sub-Element 2: State Board Requirements Under Section 128 of the CAA
    Section 110(a)(2)(E) also requires that each SIP contains 
provisions that comply with the state board requirements of section 128 
of the CAA. That provision contains two explicit requirements: (i) That 
any board or body which approves permits or enforcement orders under 
this chapter shall have at least a majority of members who represent 
the public interest and do not derive any significant portion of their 
income from persons subject to permits and enforcement orders under 
this chapter, and (ii) that any potential conflicts of interest by 
members of such board or body or the head of an executive agency with 
similar powers be adequately disclosed.
    On July 10, 2014, MDEQ submitted rules from the Civil Service Rule 
at 2-8.3(a)(1) for incorporation into the SIP, pursuant to section 128 
of the CAA. MDEQ does not have a state board. The authority to approve 
air permits and enforcement orders rest with the MDEQ Director and his 
designee. These authorities are found in MCL 324.5503, MCL 324.301(b), 
Executive Order No. 1995-18, and delegation letter from the MDEQ 
Director to the Air Quality Division chief and supervisors. Therefore, 
section 128(a)(1) of the CAA is not applicable in Michigan.
    Under section 128(a)(2), the head of the executive agency with the 
power to approve enforcement orders or permits must adequately disclose 
any potential conflicts of interest. The Civil Service Rule 2-8.3(a)(1) 
contains provisions that adequately satisfy the requirements of section 
128(a)(2). This provision requires that ``At least annually, an 
employee shall disclose to the employee's appointing authority all 
personal or financial interests of the employee or members of the 
employee's immediate family in any business or entity with which the 
employee has direct contact while performing official duties as a 
classified employee'' (Civil Service Rule 2-8.3(a)(1)). The Civil 
Service Rule 1-9.1 subjects the MDEQ Director and designees to this 
provision. Therefore, when evaluated together in the context of section 
128(a)(2), the director of MDEQ or his/her designee must fully disclose 
any potential conflicts of interest relating to permits or enforcement 
orders under the CAA. As a result, we are proposing to approve Civil 
Service Rule 2-8.3(a)(1) into the SIP. On July 10, 2014, MDEQ requested 
that these rules satisfy not only the applicable requirements of 
section 128 of the CAA, but that they satisfy any applicable 
requirements of section 110(a)(2)(E) for the 2008 ozone, 2010 
NO2, 2010 SO2, and 2012 PM2.5 NAAQS. 
Therefore, EPA is proposing that MDEQ has satisfied the applicable 
infrastructure SIP requirements for this section of 110(a)(2)(E) for 
the 2008 ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS.

F. Section 110(a)(2)(F)--Stationary Source Monitoring System

    States must establish a system to monitor emissions from stationary 
sources and submit periodic emissions reports. Each plan shall also 
require the installation, maintenance, and replacement of equipment, 
and the implementation of other necessary steps, by owners or operators 
of stationary sources to monitor emissions from such sources. The state 
plan shall also require periodic reports on the nature and amounts of 
emissions and emissions-related data from such sources, and correlation 
of such reports by each state agency with any emission limitations or 
standards established pursuant to this chapter. Lastly, the reports 
shall be available at reasonable times for public inspection.
    MDEQ implements a stationary source monitoring program under the 
authority of MCL 324.5512 and MCL 324.5503 of Act 451. Additional 
emissions testing, sampling, and reporting requirements are found in 
Michigan Administrative Code sections R 336.201 through R 336.202 and R 
336.2011 through R 336.2199. Emissions data is submitted to EPA through 
the National Emissions Inventory system and is available to the public 
online and upon request. EPA proposes that Michigan has satisfied the 
infrastructure SIP requirements of section 110(a)(2)(F) with respect to 
the 2008 ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS.

G. Section 110(a)(2)(G)--Emergency Powers

    This section requires that a plan provide for authority that is 
analogous to what is provided in section 303 of the CAA, and adequate 
contingency plans to implement such authority. The 2013 Memo states 
that infrastructure SIP submissions should specify authority, rested in 
an appropriate official, to restrain any source from causing or 
contributing to emissions which present an imminent and substantial 
endangerment to public health or welfare, or the environment.
    MDEQ has the authority to require immediate discontinuation of air 
contamination discharges that constitute an imminent and substantial 
endangerment to public health, safety, welfare, or the environment 
under MCL 324.5518 of Act 451. MCL 324.5530 provides for civil action 
by the Michigan Attorney General for a violation as just described. EPA 
proposes that Michigan has met the applicable infrastructure SIP 
requirements of section 110(a)(2)(G) related to authority to implement 
measures to restrain sources from causing or contributing to emissions 
which present an imminent and substantial endangerment to public health 
or welfare, or the environment with respect to the 2008 ozone, 2010 
NO2, 2010 SO2, and 2012 PM2.5 NAAQS.

H. Section 110(a)(2)(H)--Future SIP Revisions

    This section requires states to have the authority to revise their 
SIPs in response to changes in the NAAQS, availability of improved 
methods for attaining the NAAQS, or to an EPA finding that the SIP is 
substantially inadequate.
    MDEQ continues to update and implement needed revisions to 
Michigan's SIP as necessary to meet ambient air quality standards. 
Authority for MDEQ to adopt emissions standards and compliance 
schedules is found at MCL 324.5512 and MCL 324.5503 of Act 451. EPA 
proposes that Michigan has met the infrastructure SIP requirements of 
section 110(a)(2)(H) with respect to the 2008 ozone, 2010 
NO2, 2010 SO2, and 2012 PM2.5 NAAQS.

I. Section 110(a)(2)(I)--Nonattainment Area Plan or Plan Revisions 
Under Part D

    The CAA requires that each plan or plan revision for an area 
designated as a nonattainment area meet the applicable requirements of 
part D of the CAA. Part D relates to nonattainment areas.
    EPA has determined that section 110(a)(2)(I) is not applicable to 
the infrastructure SIP process. Instead, EPA takes action on part D 
attainment plans through separate processes.

J. Section 110(a)(2)(J)--Consultation With Government Officials; Public 
Notifications; PSD; Visibility Protection

    The evaluation of the submissions from Michigan with respect to the

[[Page 36313]]

requirements of section 110(a)(2)(J) is described below.
Sub-Element 1: Consultation With Government Officials
    States must provide a process for consultation with local 
governments and Federal Land Managers (FLMs) carrying out NAAQS 
implementation requirements.
    Michigan actively participates in the regional planning efforts 
that include business, community groups, state rule developers, 
representatives from the FLMs, and other affected stakeholders. 
Michigan Administrative Code section R 336.2816 requires that FLMs are 
provided with notification of permit applications that may impact class 
I areas. Additionally, Michigan is an active member of the Lake 
Michigan Air Directors Consortium, which consists of collaboration with 
the States of Illinois, Wisconsin, Indiana, Minnesota, and Ohio. EPA 
proposes that Michigan has met the infrastructure SIP requirements of 
this portion of section 110(a)(2)(J) with respect to the 2008 ozone, 
2010 NO2, 2010 SO2, and 2012 PM2.5 
NAAQS.
Sub-Element 2: Public Notification
    Section 110(a)(2)(J) also requires states to notify the public if 
NAAQS are exceeded in an area and must enhance public awareness of 
measures that can be taken to prevent exceedances.
    MDEQ notifies the public if there are NAAQS exceedances and of any 
public health hazards associated with those exceedances through 
CleanAirAction!, AirNow, and EnviroFlash as well as posting on its Web 
site. MDEQ published an annual air quality report comparing Michigan 
monitors to the NAAQS. EPA proposes that Michigan has met the 
infrastructure SIP requirements of this portion of section 110(a)(2)(J) 
with respect to the 2008 ozone, 2010 NO2, 2010 
SO2, and 2012 PM2.5 NAAQS.
Sub-Element 3: PSD
    States must meet applicable requirements of section 110(a)(2)(C) 
related to PSD. MDEQ's PSD program in the context of infrastructure 
SIPs has already been discussed in the paragraphs addressing section 
110(a)(2)(C) and 110(a)(2)(D)(i)(II), and EPA notes that the proposed 
actions for those sections are consistent with the proposed actions for 
this portion of section 110(a)(2)(J). Therefore, EPA proposes that 
Michigan has met all of the infrastructure SIP requirements for PSD 
associated with section 110(a)(2)(D)(J) for the 2008 ozone, 2010 
NO2, 2010 SO2, and 2012 PM2.5 NAAQS.
Sub-Element 4: Visibility Protection
    With regard to the applicable requirements for visibility 
protection, states are subject to visibility and regional haze program 
requirements under part C of the CAA (which includes sections 169A and 
169B). In the event of the establishment of a new NAAQS, however, the 
visibility and regional haze program requirements under part C do not 
change. Thus, we find that there is no new visibility obligation 
``triggered'' under section 110(a)(2)(J) when a new NAAQS becomes 
effective. In other words, the visibility protection requirements of 
section 110(a)(2)(J) are not germane to infrastructure SIPs for the 
2008 ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS.

K. Section 110(a)(2)(K)--Air Quality Modeling/Data

    SIPs must provide for performing air quality modeling for 
predicting effects on air quality of emissions of any NAAQS pollutant 
and submission of such data to EPA upon request.
    MDEQ continues to review the potential impact of major, and some 
minor, new and modified sources using computer models. Michigan's rules 
regarding air quality modeling are contained in Michigan Administrative 
Code sections R 336.1240 and R 336.1241. These modeling data are 
available to EPA or other interested parties upon request. EPA proposes 
that Michigan has met the infrastructure SIP requirements of section 
110(a)(2)(K) with respect to the 2008 ozone, 2010 NO2, 2010 
SO2, and 2012 PM2.5 NAAQS.

L. Section 110(a)(2)(L)--Permitting Fees

    This section requires that SIPs mandate that each major stationary 
source pay permitting fees to cover the cost of reviewing, approving, 
implementing, and enforcing a permit.
    MDEQ implements and operates the title V permit program, which EPA 
approved on December 4, 2001 (66 FR 62969); revisions to the program 
were approved on November 10, 2003 (68 FR 63735). MDEQ's authority to 
levy and collect an annual air quality fee from fee-subject facilities 
is found in section 324.5522 of Act 451. EPA proposes that Michigan has 
met the infrastructure SIP requirements of section 110(a)(2)(L) with 
respect to the 2008 ozone, 2010 NO2, 2010 SO2, 
and 2012 PM2.5 NAAQS.

M. Section 110(a)(2)(M)--Consultation/Participation by Affected Local 
Entities

    States must consult with and allow participation from local 
political subdivisions affected by the SIP.
    MDEQ regularly works with local political subdivisions for 
attainment planning purposes and actively participates in regional 
planning organizations. Rulemaking is subject to notice, comment, and 
hearing requirements under the Michigan Administrative Procedures Act, 
1969 PA 306 and is authorized in MCL 324.5512. EPA proposes that 
Michigan has met the infrastructure SIP requirements of section 
110(a)(2)(M) with respect to the 2008 ozone, 2010 NO2, 2010 
SO2, and 2012 PM2.5 NAAQS.

V. What action is EPA taking?

    EPA is proposing to approve most elements of submissions from MDEQ 
certifying that its current SIP is sufficient to meet the required 
infrastructure elements under sections 110(a)(1) and (2) for the 2008 
ozone, 2010 NO2, 2010 SO2, and 2012 
PM2.5 NAAQS. In addition, EPA is proposing to approve a 
submission from Michigan intended to meet the state board requirements 
of section 128, specifically the Civil Service Rule 2-8.3(a)(1).
    EPA's proposed actions for the state's satisfaction of 
infrastructure SIP requirements, by element of section 110(a)(2) are 
contained in the table below.

VI. Incorporation by Reference

    In this rule, the EPA is proposing to include in a final EPA rule 
regulatory text that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by 
reference the Michigan Civil Service Commission Rule 2-8.3(a)(1) 
entitled ``Disclosure,'' effective October 1, 2013. The EPA has made, 
and will continue to make, these documents generally available 
electronically through www.regulations.gov and/or in hard copy at the 
appropriate EPA office (see the ADDRESSES section of this preamble for 
more information).

VII. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve State choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves State law as meeting Federal requirements and 
does not impose additional requirements beyond those imposed by State 
law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4);
     does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, the SIP is not approved to apply on any Indian 
reservation land or in any other area where EPA or an Indian tribe has 
demonstrated that a tribe has jurisdiction. In those areas of Indian 
country, the rule does not have tribal implications and will not impose 
substantial direct costs on tribal governments or preempt tribal law as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
