[EPA-R05-OAR-2009-0805; EPA-R05-OAR-2012-0567; FRL-9708-9]

Approval and Promulgation of Air Quality Implementation Plans; 
Illinois; Indiana; Michigan; Minnesota; Ohio; Wisconsin; Infrastructure 
SIP Requirements for the 2006 PM2.5 National Ambient Air 
Quality Standards; Indiana NSR/PSD

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve some elements, and disapprove 
other elements, of State Implementation Plan (SIP) submissions by 
Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin regarding 
the infrastructure requirements of sections 110(a)(1) and (2) of the 
Clean Air Act (CAA) for the 2006 24-hour fine particle national ambient 
air quality standards (2006 PM2.5 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 portions of a submittal from Indiana addressing EPA's 
requirements for its new source review (NSR) and prevention of 
significant deterioration (PSD) program.

DATES: Comments must be received on or before September 4, 2012.

II. What is the background of these SIP submissions?

A. What State SIP submissions does this rulemaking address?

    This rulemaking addresses submittals from each State (and 
appropriate State agency) in EPA Region 5: Illinois Environmental 
Protection Agency (Illinois EPA); Indiana Department of Environmental 
Management (IDEM); Michigan Department of Environmental Quality (MDEQ); 
Minnesota Pollution Control Agency (MPCA); Ohio Environmental 
Protection Agency (Ohio EPA); and Wisconsin Department of Natural 
Resources Bureau of Air Management (WDNR). Each State made SIP 
submissions on the following dates: Illinois--August 9, 2011, and 
supplemented on August 25, 2011 and June 27, 2012; Indiana--October 20, 
2009, and supplemented on June 25, 2012 and July 12, 2012; Michigan--
August 15, 2011, and supplemented on July 9, 2012; Minnesota--May 23, 
2011, and supplemented on June 27, 2012; Ohio--September 4, 2009, and 
supplemented on June 3, 2011 and July 5, 2012; and, Wisconsin--January 
24, 2011, and supplemented on June 29, 2012.
    The States of Indiana and Wisconsin have also made SIP submissions 
intended to address various EPA requirements for their respective NSR 
and PSD programs. IDEM submitted revisions on July 12, 2012, for 
incorporation into its NSR and PSD program, and also requested that EPA 
approve these revisions as satisfying any applicable infrastructure SIP 
requirements for the 2006 PM2.5 NAAQS. WDNR submitted 
revisions to its NSR and PSD programs on May 12, 2011, and while the 
SIP submission was not explicitly made to satisfy the infrastructure 
SIP requirements for the 2006 PM2.5 NAAQS, a discussion of 
the relevant infrastructure SIP requirements and the State's 
satisfaction of these requirements is contained in the paragraphs 
addressing section 110(a)(2)(C).

B. Why did the States make these SIP submissions?

    Under sections 110(a)(1) and (2) of the CAA, and implementing EPA 
policy, the States are required to submit infrastructure SIPs to ensure 
that their SIPs provide for implementation, maintenance, and 
enforcement of the NAAQS, including the 2006 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 particulate matter already met 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). 
States were required to make SIP submissions meeting the requirements 
to EPA within three years after promulgation of the revised standards. 
The three-year submittal window was reiterated in a September 25, 2009, 
EPA-issued guidance document pertaining to the 2006 PM2.5 
NAAQS entitled ``Guidance on SIP Elements Required Under Sections 
110(a)(1) and (2) for the 2006 24-Hour Fine Particle (PM2.5) 
National Ambient Air Quality Standards (NAAQS)'' (2009 Memo). Because 
the finalized 2006 PM2.5 NAAQS was signed and widely 
disseminated on September 21, 2006, the due date for infrastructure SIP 
submissions to EPA was September 21, 2009. The certifications 
referenced in this rulemaking pertain to the applicable requirements of 
sections 110(a)(1) and (2) of the CAA. The SIP submissions from the six 
Region 5 States being evaluated here address only the 2006 
PM2.5 NAAQS, and the proposed rulemaking addresses only this 
pollutant as well.\1\
---------------------------------------------------------------------------

    \1\ On June 14, 2012, the Administrator of EPA signed a proposed 
rule that would strengthen various aspects of the existing 
PM2.5 NAAQS (see 77 FR 38890). The State submittals and 
EPA's rulemaking do not extend to these proposed NAAQS.
---------------------------------------------------------------------------

C. What is the scope of this rulemaking?

    This rulemaking will not cover four substantive issues 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

[[Page 45994]]

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''); (iii) existing 
provisions for minor source NSR programs that may be inconsistent with 
the requirements of the CAA and EPA's regulations that pertain to such 
programs (``minor source NSR''); and, (iv) existing provisions for PSD 
programs that may be inconsistent with current requirements of EPA's 
``Final NSR Improvement Rule,'' 67 FR 80186 (December 31, 2002), as 
amended by 72 FR 32526 (June 13, 2007) (``NSR Reform''). Instead, EPA 
has committed to address each of these four issues in separate 
rulemakings. A detailed rationale for why these four substantive issues 
are not part of the scope of infrastructure SIP rulemakings can be 
found in EPA's July 13, 2011, final rule entitled, ``Infrastructure SIP 
Requirements for the 1997 8-hour Ozone and PM2.5 National 
Ambient Air Quality Standards'' in the section entitled, ``What is the 
scope of this final rulemaking?'' (see 76 FR 41075 at 41076-41079).
    In addition to the four substantive issues above, EPA is not acting 
on portions of section 110(a)(2)(D)(i)(II)--Interstate transport; 
section 110(a)(2)(E)(ii)--Adequate resources; and section 
110(a)(2)(J)--Consultation with government officials, public 
notifications, PSD, and visibility protection. EPA is also not acting 
on section 110(a)(2)(I)--Nonattainment Area Plan or Plan Revisions 
Under Part D, in its entirety. The rationale for not acting on elements 
of these requirements is discussed below.

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 this memorandum 
(Required Section 110 SIP Elements) identified the statutory elements 
that states need to meet in order to satisfy the requirements for an 
infrastructure SIP submission. The 2009 Memo was issued to provide 
additional guidance for certain elements to meet the requirements of 
section 110(a)(1) and (2) of the CAA for 2006 PM2.5 NAAQS. 
Where appropriate, EPA will reference the guidance contained in both 
the 2007 Memo and the 2009 Memo as they pertain to the Region 5 States' 
submissions.

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

    The six States in Region 5 have certified that they meet the 
applicable requirements of sections 110(a)(1) and 110(a)(2) without 
further revisions to their respective SIPs for the 2006 
PM2.5 NAAQS. Therefore, consistent with the 2009 Memo, EPA 
believes that no public hearing or comment process was necessary at the 
State level for this NAAQS.\2\ Nevertheless, the public will now have 
the opportunity to comment on EPA's evaluation of each certification 
through our notice-and-comment rulemaking process. Illinois EPA, IDEM, 
MDEQ, MPCA, Ohio EPA, and WDNR provided detailed synopses of how 
various components of their respective SIPs meet each of the 
requirements in section 110(a)(2), as applicable. The following review 
evaluates the six States' submissions.
---------------------------------------------------------------------------

    \2\ Although the public hearing process was not necessary at the 
State level, Ohio EPA held a public hearing on August 13, 2009, and 
provided an opportunity for written comments as well. No comments 
were received in person, or in writing.
---------------------------------------------------------------------------

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. The specific nonattainment area 
plan requirements of section 110(a)(2)(I), however, are subject to the 
timing requirements of section 172, not the timing requirement of 
section 110(a)(1). Thus, section 110(a)(2)(A) does not require that 
states submit regulations or emissions limits specifically for 
attaining the 2006 PM2.5 NAAQS. Those SIP provisions are due 
as part of each state's attainment plan, and will be addressed 
separately from the requirements of section 110(a)(2)(A). 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.
    The Illinois Environmental Protection Act is contained in chapter 
415, section 5, of the Illinois Compiled Statutes (415 ILCS 5). 415 
ILCS 5/4 provides the Director of Illinois EPA with the authority to 
develop rules and regulations necessary to meet ambient air quality 
standards. Additionally, the Illinois Pollution Control Board (IPCB) 
was created under 415 ILCS 5, providing the IPCB with the authority to 
develop rules and regulations necessary to promote the purposes of the 
Illinois Environmental Protection Act. Furthermore, the IPCB ensures 
compliance with required laws and other elements of the State's 
attainment plan that are necessary to attain the NAAQS, and to comply 
with the requirements of the CAA. (415 ILCS 5/10) EPA proposes that 
Illinois has met the infrastructure SIP requirements of section 
110(a)(2)(A) with respect to the 2006 PM2.5 NAAQS.
    IDEM's authority to adopt emissions standards and compliance 
schedules is found at Indiana Code (IC) 13-14-8, IC 13-17-3-4, IC 13-
17-3-11, and IC 13-17-3-14. EPA proposes that Indiana has met the 
infrastructure SIP requirements of section 110(a)(2)(A) with respect to 
the 2006 PM2.5 NAAQS.
    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. EPA 
proposes that Michigan has met the infrastructure SIP requirements of 
section 110(a)(2)(A) with respect to the 2006 PM2.5 NAAQS.
    Minnesota Statute chapter 116.07 gives MPCA the authority to 
``[a]dopt, amend, and rescind rules and standards having the force of 
law relating to any purpose * * * for the prevention, abatement, or 
control of air pollution.'' EPA proposes that Minnesota has met the 
infrastructure SIP requirements of section 110(a)(2)(A) with respect to 
the 2006 PM2.5 NAAQS.
    Ohio Revised Code (ORC) 3704.03 provides the Director of Ohio EPA 
with the authority to develop rules and regulations necessary to meet 
State and Federal ambient air quality standards. EPA proposes that Ohio 
has met the infrastructure SIP requirements of section 110(a)(2)(A) 
with respect to the 2006 PM2.5 NAAQS.
    Wisconsin Statutes (WS) chapter 285.11 through WS chapter 285.19 
establish general authority for monitoring, updating, and implementing 
necessary revisions to the Wisconsin SIP. Additional authorities 
related to specific pollutants are contained in WS chapter 285.21 
through WS chapter 285.29. EPA proposes that Wisconsin has met the 
infrastructure SIP requirements of section 110(a)(2)(A) with respect to 
the 2006 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).

[[Page 45995]]

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. EPA is evaluating compliance with section 
110(a)(2)(B) in infrastructure SIP submissions by verifying that the 
state has submitted an annual monitoring plan for the relevant NAAQS, 
and that EPA has approved the most recent plan. 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.
    Illinois EPA continues to operate an extensive monitoring network 
incorporating more than 200 monitors throughout the State. Illinois EPA 
also publishes an annual report that summarizes air quality trends. 
Furthermore, Illinois EPA submits yearly monitoring network plans to 
EPA, and EPA approved the 2012 Annual Air Monitoring Network Plan for 
PM2.5 on December 19, 2011. Monitoring data from Illinois 
EPA are entered into AQS in a timely manner, and the State provides EPA 
with prior notification when changes to its monitoring network or plan 
are being considered. EPA proposes that Illinois has met the 
infrastructure SIP requirements of section 110(a)(2)(B) with respect to 
the 2006 PM2.5 NAAQS.
    IDEM continues to operate an air monitoring network; EPA approved 
the State's 2012 Annual Air Monitoring Network Plan for 
PM2.5 on January 3, 2012, including the plan for 
PM2.5. EPA noted, however, that IDEM should continue to 
search for a suitable replacement location for one monitoring site. 
IDEM 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 Indiana has met the 
infrastructure SIP requirements of section 110(a)(2)(B) with respect to 
the 2006 PM2.5 NAAQS.
    MDEQ maintains a comprehensive network of air quality monitors 
throughout Michigan. EPA approved MDEQ's 2012 Annual Air Monitoring 
Network Plan on December 19, 2011. 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 2006 PM2.5 NAAQS.
    MPCA continues to operate an ambient pollutant monitoring network, 
and compiles and reports air quality data to EPA. EPA approved MPCA's 
2012 Annual Air Monitoring Network Plan for PM2.5 on 
December 19, 2011. MPCA also provides prior notification to EPA when 
changes to its monitoring network or plan are being considered. EPA 
proposes that Minnesota has met the infrastructure SIP requirements of 
section 110(a)(2)(B) with respect to the 2006 PM2.5 NAAQS.
    Ohio EPA continues to operate a monitoring network; EPA approved 
the State's 2012 Annual Air Monitoring Network Plan for 
PM2.5 on January 11, 2012. Furthermore, Ohio EPA populates 
AQS with air quality monitoring data in a timely manner, and provides 
EPA with prior notification when considering a change to its monitoring 
network or plan. EPA proposes that Ohio has met the infrastructure SIP 
requirements of section 110(a)(2)(B) with respect to the 2006 
PM2.5 NAAQS.
    WDNR continues to operate an extensive monitoring network; EPA 
approved the State's 2012 Annual Air Monitoring Network Plan for 
PM2.5 on January 3, 2012. WDNR enters air quality data into 
AQS in a timely manner, and gives EPA prior notification when 
considering a change to its monitoring network or plan. EPA proposes 
that Wisconsin has met the infrastructure SIP requirements of section 
110(a)(2)(B) with respect to the 2006 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 the PSD and 
nonattainment new source review (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 the Region 5 States' certifications addressing 
the infrastructure SIP requirements of section 110(a)(2)(C) covers: (i) 
Enforcement of SIP measures; (ii) identification of precursors to 
PM2.5 in the PSD program; (iii) identification of 
PM2.5 condensables in the PSD program; (iv) oxides of 
nitrogen (NOx) as a precursor to ozone in the PSD program; and, (v) 
greenhouse gas (GHG) permitting and the ``Tailoring Rule.''
Sub-Element 1: Enforcement of SIP Measures
    Illinois continues to staff and implement an enforcement program 
comprised, and operated by, the Compliance Section and Division of 
Legal Counsel. 415 ILCS 5/4 provides the Director of Illinois EPA with 
the authority to implement and administer this enforcement program. 
Furthermore, Illinois EPA has confirmed that all enforcement actions 
are brought by the Office of the Illinois Attorney General or local 
State's Attorney offices, with whom Illinois EPA consults. EPA proposes 
that Illinois has met the enforcement of SIP measures requirements of 
section 110(a)(2)(C) with respect to the 2006 PM2.5 NAAQS.
    IDEM maintains an enforcement program to ensure compliance with SIP 
requirements. IC 13-14-1-12 provides the Commissioner with the 
authority to enforce rules ``consistent with the purpose of the air 
pollution control laws.'' Additionally, IC 13-14-2-7 and IC 13-17-3-3 
provide the Commissioner with the authority to assess civil penalties 
and obtain compliance with any applicable rule a board has adopted in 
order to enforce air pollution control laws. Lastly, IC 13-14-10-2 
allows for an emergency restraining order that prevents any person from 
causing, or introducing contaminants, that cause or contribute to air 
pollution. EPA proposes that Indiana has met the enforcement of SIP 
measures requirements of section 110(a)(2)(C) with respect to the 2006 
PM2.5 NAAQS.
    MDEQ continues to staff and implement an enforcement program to 
assure compliance with all requirements under State law, consistent 
with the provisions of Act 451. Additionally, this Air Quality 
Enforcement Unit provides support and technical assistance to 
Michigan's Attorney General on all air pollution enforcement issues 
referred by MDEQ's Air Quality Division for escalated enforcement 
action. Lastly, the air quality enforcement unit at MDEQ coordinates 
formal administrative actions such as contested case hearings, 
administrative complaints, and revocation of permits to install. 
Therefore, EPA proposes that Michigan has met the enforcement of SIP 
measures requirements of section 110(a)(2)(C) with respect to the 2006 
PM2.5 NAAQS.
    Minnesota Statute chapter 116.07 gives the MPCA the authority to 
enforce

[[Page 45996]]

any provisions of the chapter relating to air contamination. These 
provisions include: entering into orders; schedules of compliance; 
stipulation agreements; requiring owners or operators of emissions 
facilities to install and operate monitoring equipment; and conducting 
investigations. Minnesota Statute chapter 116.072 authorizes MPCA to 
issue orders and assess administrative penalties to correct violations 
of the agency's rules, statutes, and permits. Lastly, Minnesota Statute 
Chapter 115.071 outlines the remedies that are available to address 
such violations. EPA proposes that Minnesota has met the enforcement of 
SIP measures requirements of section 110(a)(2)(C) with respect to the 
2006 PM2.5 NAAQS.
    Ohio EPA staffs and implements an enforcement program. ORC 3704.03 
provides the Director of Ohio EPA with the authority to implement the 
enforcement program as well as the updated NSR provisions within Ohio 
Administrative Code (OAC) 3745-31. Ohio EPA compiles all air pollution 
control enforcement settlements in the State, and makes them available 
for public review on its Web site. EPA proposes that Ohio has met the 
enforcement of SIP measures requirements of section 110(a)(2)(C) with 
respect to the 2006 PM2.5 NAAQS.
    WDNR maintains an enforcement program to ensure compliance with SIP 
requirements. The Bureau of Air Management houses an active Statewide 
Compliance and Enforcement Team that works in all geographic regions of 
the State. WDNR refers most actions to the Wisconsin Department of 
Justice with the involvement of WDNR. Under WS chapter 285.13, the 
agency has the authority to impose fees and penalties to ensure that 
required measures are ultimately implemented. WS chapter 285.83 and WS 
chapter 285.87 provide the authority to enforce violations and assess 
penalties. EPA proposes that Wisconsin has met the enforcement of SIP 
measures requirements of section 110(a)(2)(C) with respect to the 2006 
PM2.5 NAAQS.
Sub-Element 2: Identification of Precursors to PM2.5 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, the EPA identified precursors to 
PM2.5 for the PSD program to be sulfur dioxide 
(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 volatile organic compounds (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) and 40 CFR 52.21(b)(50)(i). 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).
    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).
    Illinois and Minnesota have not adopted or submitted regulations 
for PSD, although Federally promulgated rules for this purpose are in 
effect in these two States, promulgated at 40 CFR 52.21. EPA has 
currently delegated the authority to implement these regulations to 
Illinois and Minnesota. These Federally promulgated rules include 
provisions establishing precursors to PM2.5 both in the 
definition of ``regulated NSR pollutant'' and ``significant.'' EPA 
acknowledges that the States have not satisfied the requirement for a 
SIP submission, which results in a proposed disapproval with respect to 
this set of infrastructure SIP requirements of section 110(a)(2)(C). 
However, Illinois and Minnesota have no further obligations to EPA 
because both States administer the Federally promulgated PSD 
regulations.
    Indiana submitted revisions to its PSD program incorporating the 
necessary changes regarding PM2.5 precursors on July 12, 
2012. In this rulemaking, we are proposing to approve portions of these 
revisions for incorporation into Indiana's SIP, and we are also 
proposing to find that Indiana has met this set of requirements of 
section 110(a)(2)(C) for the 2006 PM2.5 NAAQS. Specifically, 
changes to 326 Indiana Administrative Code (IAC) 2-2-1(ss), ``Regulated 
NSR pollutant,'' have been made to explicitly identify SO2 
and NOX as precursors to PM2.5 that will be 
evaluated in NSR permit contexts. Additionally, IDEM has also specified 
that VOCs are not presumed to be precursors to PM2.5.\3\ The 
definition of ``Significant'' has been revised at 326 IAC 2-2-
1(ww)(1)(F) to identify the significant emissions rates for direct 
PM2.5, and SO2 and NOX as its 
precursors, consistent with the 2008 NSR Rule. EPA is proposing to 
approve these revisions into the SIP, and also proposes that Indiana 
has met this set of infrastructure SIP requirements of section 
110(a)(2)(C) with respect to the 2006 PM2.5 NAAQS.
---------------------------------------------------------------------------

    \3\ Indiana has also specified that ammonia is not a presumed 
precursor to PM2.5. Ammonia is relevant only in the 
context of NNSR; for the purposes of this rulemaking related to 
structural PSD elements, EPA observes that Indiana has properly 
identified VOCs as not being a presumed PM2.5 precursor.
---------------------------------------------------------------------------

    Michigan is in the process of adopting revisions to its PSD program 
that incorporate the necessary changes regarding PM2.5 
precursors. Specifically, changes to the Part 18 Rules (R 336.2801-R 
336.2823) have been filed at the State level, and MDEQ has committed to 
submitting the revisions for incorporation into the SIP when the rules 
are adopted at the State level. Although the State has made a specific 
commitment to EPA to make the submission required by the 2008 NSR Rule, 
the deadline for when states must submit those SIP revisions has since 
passed. Therefore, EPA is proposing to disapprove this narrow portion 
of Michigan's infrastructure SIP submission for the 2006 
PM2.5 NAAQS with respect to the requirements of section 
110(a)(2)(C) regarding the identification of PM2.5 
precursors for NSR permitting.
    Ohio is in the process of adopting revisions to its PSD program 
that incorporate the necessary changes regarding PM2.5 
precursors. Specifically, draft changes are being made to OAC 3745-31-
01, and Ohio has committed to submitting the revisions for 
incorporation into the SIP when final rules are adopted at the State 
level. For the same reasons discussed above for

Michigan, EPA is proposing to disapprove this narrow portion of Ohio's 
infrastructure SIP submission for the 2006 PM2.5 NAAQS with 
respect to the requirements of section 110(a)(2)(C) regarding the 
identification of PM2.5 precursors for NSR permitting.
    Wisconsin submitted revisions to its PSD program on May 12, 2011, 
intended to meet the requirements of the 2008 NSR Rule. Specifically, 
WDNR's revisions to NR 405.02(27)(a)(5) include the significant 
emissions rates for direct PM2.5, and SO2 and 
NOX as PM2.5 precursors, consistent with the 2008 
NSR Rule. However, Wisconsin's PSD regulations include only generic 
language to define what constitutes a regulated NSR pollutant that does 
not directly account for PM2.5 and its precursors in NSR 
permitting. NR 405(02)(25i) defines ``Regulated NSR air contaminant'' 
as ``[a]ny air contaminant for which a national ambient air quality 
standard has been promulgated and any constituents or precursors for 
the air contaminants identified by the administrator * * *.'' The 2008 
NSR Rule obligates the State to explicitly identify the precursors to 
PM2.5 to be addressed in NSR permitting as part of the 
definition for ``Regulated NSR air contaminant.'' EPA notes that 
although Wisconsin has incorporated the significant emissions rates in 
accordance with the 2008 NSR Rule, WDNR has not explicitly identified 
SO2 and NOX as precursors to PM2.5 in 
defining pollutants regulated by the PSD program. Therefore, we are 
proposing to disapprove this narrow portion of Wisconsin's 
infrastructure SIP submission for the 2006 PM2.5 NAAQS with 
respect to the requirements of section 110(a)(2)(C) regarding the 
identification of PM2.5 precursors.
Sub-Element 3: Identification of Condensables in the PSD Program
    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\4\ emission 
limits in NSR permits. Instead, EPA determined that states had to 
account for PM2.5 and PM10 condensables beginning 
on or after January 1, 2011. This requirement is codified in 40 CFR 
51.166(b)(49)(vi) and 40 CFR 52.21(b)(50)(vi). 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).

    \4\ PM10 refers to particles with diameters between 
2.5 and 10 microns, oftentimes referred to as ``coarse'' particles.
---------------------------------------------------------------------------

    Illinois and Minnesota have not adopted or submitted regulations 
for PSD, although Federal rules for this purpose, promulgated at 40 CFR 
52.21, are in effect in these two States. EPA has currently delegated 
the authority to implement these regulations to Illinois and Minnesota. 
These Federally promulgated rules include provisions defining 
``regulated NSR pollutant'' to include condensables for 
PM2.5 and PM10. EPA acknowledges that the States 
have not satisfied the requirement for a SIP submission, which results 
in a proposed disapproval with respect to this set of infrastructure 
SIP requirements of section 110(a)(2)(C). However, Illinois and 
Minnesota have no further obligations to EPA because both States 
administer the Federally promulgated PSD regulations.
    Indiana submitted revisions to its PSD program incorporating the 
necessary changes regarding PM2.5 and PM10 
condensables on July 12, 2012. Specifically, 326 IAC 2-1.1-1(2) has 
been revised to account for condensables in the definition of ``Direct 
PM2.5,'' and analogous changes were made at 326 IAC 2-1.1-
1(10) for ``Direct PM10.'' EPA is proposing to approve these 
revisions into the SIP, and also proposes that Indiana has met the 
infrastructure SIP requirements of section 110(a)(2)(C) to account for 
PM2.5 and PM10 condensables with respect to the 
2006 PM2.5 NAAQS.
    Michigan is in the process of adopting revisions to its regulations 
that incorporate the necessary changes regarding PM2.5 and 
PM10 condensables. Changes to Part 1 Rules (R 336.1101-R 
336.1128) have been filed at the State level, and MDEQ has committed to 
submitting the revisions for incorporation into the SIP when the rules 
are adopted at the State level. However, for the same reasons discussed 
above regarding the identification of PM2.5 precursors, EPA 
is proposing to disapprove this narrow portion of Michigan's 
infrastructure SIP submission for the 2006 PM2.5 NAAQS with 
respect to the requirements of section 110(a)(2)(C) regarding the 
regulation of PM2.5 and PM10 condensables in the 
PSD program.
    Ohio is in the process of adopting revisions to its regulations 
that incorporate the necessary changes regarding PM2.5 and 
PM10 condensables. Specifically, draft changes are being 
made to OAC 3745-31-01, and Ohio has committed to submitting the 
revisions for incorporation into the SIP when final rules are adopted 
at the State level. However, for the same reasons described above, EPA 
is proposing to disapprove this narrow portion of Ohio's infrastructure 
SIP submission for the 2006 PM2.5 NAAQS with respect to the 
requirements of section 110(a)(2)(C) regarding the regulation of 
PM2.5 and PM10 condensables in the PSD program.
    Wisconsin submitted revisions to its PSD program on May 12, 2011. 
However, these revisions do not incorporate the necessary changes 
regarding the regulation of condensables for PM2.5 and 
PM10, nor does Wisconsin's existing SIP account for 
PM2.5 and PM10 condensables. Therefore, EPA is 
proposing to disapprove this narrow portion of Wisconsin's 
infrastructure SIP submission for the 2006 PM2.5 NAAQS with 
respect to the requirements of section 110(a)(2)(C) regarding the 
regulation of PM2.5 and PM10 condensables in the 
PSD program.
Sub-Element 4: 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 8, 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, and consisted of the following\5\:
---------------------------------------------------------------------------

    \5\ Similar changes were codified in 40 CFR 52.21.

    40 CFR 51.166(b)(1)(ii): A major source that is major for 
volatile organic compounds or NOX shall be considered 
major for ozone;
    40 CFR 51.166(b)(2)(ii): Any significant emissions increase (as 
defined at paragraph (b)(39) of this section) from any emissions 
units or net emissions increase (as defined in paragraph (b)(3) of 
this section) at a major stationary source that is significant for

ambient air quality standard has been promulgated and any 
constituents or precursors for such pollutants identified by the 
Administrator (e.g., volatile organic compounds and NOX) 
are precursors for ozone; and
    40 CFR 51.166(i)(5)(i)(e) footnote 1: No de minimis air quality

subject to PSD would be required to perform an ambient impact 
analysis, including the gathering of air quality data.

    The Phase 2 Rule required that states submit SIP revisions 
incorporating the requirements of the rule, including these specific 
NOX as a precursor to ozone provisions, by June 15, 2007 
(see 70 FR 71612 at 71683).
    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 
pollutants in PSD permits. In other words, if a state lacks provisions 
needed to address NOX as a precursor to ozone, the 
provisions of section 110(a)(2)(C) requiring a suitable PSD permitting 
program must be considered not to be met irrespective of the pollutant 
being addressed (see 76 FR 23757 at 23760). In the same April 28, 2011, 
notice, we proposed to approve all six Region 5 States' infrastructure 
SIPs with respect to the NOX as a precursor to ozone 
provisions in the PSD program requirements of section 110(a)(2)(C).
    In our July 13, 2011, final rulemaking for the 1997 ozone and 
PM2.5 NAAQS infrastructure SIPs, EPA finalized approval of 
the portions of the infrastructure SIPs from Indiana, Michigan, and 
Ohio with respect to the NOX as a precursor to ozone 
provisions requirement of section 110(a)(2)(C). However, EPA 
subsequently realized that these three States also lacked sufficient 
provisions to identify NOX as a precursor to ozone in their 
respective PSD programs, as required by the Phase 2 Rule.
    In lieu of an error correction pursuant to section 110(k)(6) of the 
CAA, EPA informed Indiana, Michigan, and Ohio of the factual matter 
that portions of their infrastructure SIPs intended to address 
NOX as a precursor to ozone provisions were approved as an 
oversight. We committed to work with these States to address the 
NOX as a precursor to ozone provisions, consistent with the 
requirements of the Phase 2 Rule, in the next infrastructure SIP 
rulemaking, i.e., today's rulemaking.
    Illinois and Minnesota have not adopted or submitted regulations 
for PSD, although Federally promulgated rules for this purpose are in 
effect in these two States, promulgated at 40 CFR 52.21. EPA has 
currently delegated the authority to implement these regulations to 
Illinois and Minnesota. These Federally promulgated rules include 
provisions that explicitly identify NOX as a precursor to 
ozone. EPA acknowledges that the States have not satisfied the 
requirement for a SIP submission, which results in a proposed 
disapproval with respect to this set of infrastructure SIP requirements 
of section 110(a)(2)(C). However, Illinois and Minnesota have no 
further obligations to EPA because both States administer the Federally 
promulgated PSD regulations.
    On July 12, 2012, Indiana submitted revisions to its PSD program 
incorporating the necessary changes regarding NOX as a 
precursor to ozone, consistent with the requirements of the Phase 2 
Rule. In this rulemaking, we are proposing to approve these revisions 
to Indiana's SIP, and we are also proposing to find that Indiana has 
met this set of requirements of section 110(a)(2)(C) for the 2006 
PM2.5 NAAQS. Specifically, Indiana has revised the following 
sections to align with EPA's own regulations contained in 40 CFR 
51.166: 326 IAC 2-2-1(dd)(1): 40 CFR 51.166(b)(2)(ii); 326 IAC 2-2-
1(ff)(7): 40 CFR 51.166(b)(1)(ii); 326 IAC 2-2-1(ss)(1): 40 CFR 
51.166(b)(49)(i); 326 IAC 2-2-1(ww)(1)(G): 40 CFR 51.166(b)(23)(i); 
and, 326 IAC 2-2-4(b)(2)(vi): footnote to 40 CFR 51.166 (i)(5)(i)(e). 
EPA is proposing to approve these revisions into the SIP, and also 
proposes that Indiana has met the requirements of section 110(a)(2)(C) 
with respect to the 2006 PM2.5 NAAQS regarding the explicit 
identification of NOX as a precursor to ozone, consistent 
with the Phase 2 Rule.
    Michigan is in the process of adopting revisions to its PSD program 
that incorporate the necessary changes regarding the explicit 
identification of NOX as a precursor to ozone, consistent 
with the requirements of the Phase 2 Rule. Specifically, changes to the 
Part 18 Rules (R 336.2801--R 336.2823) have been filed at the State 
level, and MDEQ has committed to submitting the revisions for 
incorporation into the SIP when the rules are adopted at the State 
level. However, consistent with actions in Region 5 and other regions 
germane to the explicit identification of NOX as a precursor 
to ozone in PSD programs, EPA is proposing to disapprove this narrow 
portion of Michigan's infrastructure SIP for the 2006 PM2.5 
NAAQS with respect to the requirements of section 110(a)(2)(C) 
regarding the explicit identification of NOX as a precursor 
to ozone in the PSD program.
    Ohio is in the process of adopting revisions to its PSD program 
that incorporate the necessary changes regarding the explicit 
identification of NOX as a precursor to ozone, consistent 
with the Phase 2 Rule. Specifically, draft changes are being made to 
OAC 3745-31-01, and Ohio has committed to submitting the revisions for 
incorporation into the SIP when final rules are adopted at the State 
level. For the same reasons discussed above, EPA is proposing to 
disapprove this narrow portion of Ohio's infrastructure SIP for the 
2006 PM2.5 NAAQS with respect to the requirements of section 
110(a)(2)(C) regarding the explicit identification of NOX as 
a precursor to ozone in the PSD program.
    During the comment period following the April 28, 2011, notice, two 
commenters observed that although we proposed to approve Wisconsin's 
infrastructure SIP as meeting the correct requirements for 
NOX as a precursor to ozone in the State's PSD program, 
Wisconsin's PSD SIP does not contain the most recent PSD program 
revisions required by EPA for this purpose. A subsequent review of 
Wisconsin's PSD SIP indicated that the commenters were correct in their 
assertion. Specifically, Wisconsin had not made necessary revisions to 
its PSD program with respect to the identification of NOX as 
a precursor to ozone, consistent with the explicit requirements of the 
Phase 2 Rule. As a result, EPA could not finalize this portion of 
Wisconsin's infrastructure SIP for the 1997 ozone and PM2.5 
NAAQS in our July 13, 2011, final rulemaking. Instead, a subsequent set 
of actions led EPA to disapprove Wisconsin's infrastructure SIP for 
this narrow portion of section 110(a)(2)(C) with respect to the 1997 
ozone and PM2.5 NAAQS on June 15, 2012 (see 77 FR 35870). A 
detailed rationale for our disapproval can be found in the associated 
April 20, 2012, proposed rulemaking (see 77 FR 23647).
    This final disapproval triggered the requirement under section 
110(c) that EPA promulgate a Federal Implementation Plan (FIP) no later 
than two years from the date of the disapproval unless the State 
corrects the deficiency, and the Administrator approves the plan or 
plan revision before the Administrator promulgates such FIP. Wisconsin 
has not made a subsequent submittal to address the NOX as a 
precursor to ozone provisions per the Phase 2 Rule. To clarify, EPA is 
not proposing to approve or disapprove any portion of Wisconsin's 
infrastructure SIP for the 2006 PM2.5 NAAQS as it relates to 
NOX as a precursor to ozone provisions, specifically because 
we have already finalized disapproval of these provisions for the 1997 
ozone and PM2.5 NAAQS infrastructure SIPs. However, as 
discussed above, we are proposing to disapprove portions of Wisconsin's 
infrastructure SIP for the 2006 PM2.5 NAAQS with respect to 
certain requirements obligated by the 2008 NSR

Rule, including the explicit identification of NOX as a 
precursor to PM2.5.
Sub-Element 5: GHG Permitting and the ``Tailoring Rule''
    On June 3, 2010, EPA issued a final rule establishing a ``common 
sense'' approach to addressing GHG emissions from stationary sources 
under the CAA permitting programs. The ``Prevention of Significant 
Deterioration and Title V Greenhouse Gas Tailoring Rule,'' or 
``Tailoring Rule,'' set thresholds for GHG emissions that define when 
permits under the NSR PSD and title V operating permit programs are 
required for new and existing industrial facilities (75 FR 31514). The 
Tailoring Rule set the GHG PSD applicability threshold at 75,000 tpy as 
expressed in carbon dioxide equivalent; if states have not adopted this 
threshold, sources with GHG emissions above 100 tpy or 250 tpy 
(depending on source category) would be subject to PSD, effective 
January 2, 2011. The lower thresholds could potentially result in 
apartment complexes, strip malls, small farms, restaurants, etc. 
triggering GHG PSD requirements.
    On December 23, 2010, EPA issued a subsequent series of rules that 
put the necessary framework in place to ensure that industrial 
facilities can get CAA permits covering their GHG emissions when 
needed, and that facilities emitting GHGs at levels below those 
established in the Tailoring Rule do not need to obtain CAA permits.\6\ 
Included in this series of rules was EPA's issuance of the ``Limitation 
of Approval of Prevention of Significant Deterioration Provisions 
Concerning Greenhouse Gas Emitting-Sources in State Implementation 
Plans,'' referred to as the PSD SIP ``Narrowing Rule'' on December 30, 
2010 (75 FR 82536). The Narrowing Rule limits, or ``narrows,'' EPA's 
approval of PSD programs that were previously approved into SIPs; the 
programs in question are those that apply PSD to sources that emit GHG. 
Specifically, the effect of the Narrowing Rule is that provisions that 
are no longer approved--e.g., portions of already approved SIPs that 
apply PSD to GHG emissions increases from sources emitting GHG below 
the Tailoring Rule thresholds--now have the status of having been 
submitted by the state but not yet acted upon by EPA. In other words, 
the Narrowing Rule focuses on eliminating the PSD obligations under 
Federal law for sources below the Tailoring Rule thresholds. Each 
Region 5 State's status with respect to its GHG PSD program, as well as 
EPA's proposed actions, is discussed below.
---------------------------------------------------------------------------

    \6\ http://www.epa.gov/NSR/actions.html#2010.
---------------------------------------------------------------------------

    Illinois and Minnesota have not adopted or submitted regulations 
for PSD, although Federally promulgated rules for this purpose are in 
effect in these two States, promulgated at 40 CFR 52.21. EPA has 
currently delegated the authority to implement these regulations to 
Illinois and Minnesota. These Federally promulgated rules contain the 
GHG thresholds as outlined in the Tailoring Rule. EPA acknowledges that 
the States have not satisfied the requirement for a SIP submission, 
which results in a proposed disapproval with respect to this set of 
infrastructure SIP requirements of section 110(a)(2)(C). However, 
Illinois and Minnesota have no further obligations to EPA because both 
States administer the Federally promulgated PSD regulations. Note, 
however, that EPA does propose that Illinois and Minnesota have met the 
requirement contained in section 110(a)(2)(E) regarding resources 
specific to permitting GHG.\7\
---------------------------------------------------------------------------

    \7\ Section 110(a)(2)(E) requires that States have the resources 
to administer an air quality management program. Some States that 
are not covered by the Narrowing Rule may not be able to adequately 
demonstrate that they have adequate personnel to issue GHG permits 
to all sources that emit GHG under the Tailoring Rule thresholds.
---------------------------------------------------------------------------

    EPA finalized approval of revisions to Indiana's PSD SIP on 
September 28, 2011 (see 76 FR 59899). These revisions included the 
adoption of the Federal thresholds for PSD permitting of GHG-emitting 
sources. On June 25, 2012, Indiana clarified that they intended for our 
September 28, 2011 approval to satisfy applicable GHG requirements 
related to their 2006 PM2.5 NAAQS infrastructure SIP. 
Therefore, EPA proposes that Indiana's GHG permitting program has met 
this set of requirements related to section 110(a)(2)(C) and (E) for 
the 2006 PM2.5 NAAQS.
    On July 27, 2010, Michigan informed EPA that the State has both the 
legal and regulatory authority, as well as the resources, to permit GHG 
under its SIP-approved PSD permitting program, consistent with the 
thresholds laid out in the Tailoring Rule.\8\ Therefore, EPA proposes 
that Michigan's GHG PSD permitting program has met this set of 
requirements of sections 110(a)(2)(C) and (E) for the 2006 
PM2.5 NAAQS.

    \8\ Letter from the Director of MDEQ to EPA Region 5 Regional 
Administrator dated July 27, 2010.
---------------------------------------------------------------------------

    The States of Ohio and Wisconsin have the legal authority under 
their approved PSD SIPs to regulate GHGs as part of their PSD 
permitting programs. In the PSD SIP Narrowing Rule, EPA narrowed its 
previous approval of these States' PSD programs to ensure that the 
Federally approved PSD programs in these two States only require PSD 
permitting of sources emitting GHG at or above the thresholds 
established in the Tailoring Rule.
    On June 3, 2011, Ohio EPA transmitted a letter confirming that its 
2006 PM2.5 infrastructure SIP submittal before our review 
includes only those parts of their PSD SIP that remain approved after 
the PSD SIP Narrowing Rule. On March 28, 2011, Wisconsin transmitted a 
similar letter for the purposes of satisfying the same requirements for 
the 1997 ozone and PM2.5 NAAQS infrastructure SIPs. 
Wisconsin also submitted revisions to its PSD program on May 4, 2011, 
adopting the Federal thresholds for GHG emitting sources. EPA is taking 
separate action on Wisconsin's May 4, 2011, submission, but for the 
purposes of evaluating WDNR's infrastructure SIP for the 2006 
PM2.5 NAAQS, EPA notes that the portions of Wisconsin's 
submittal before our review include only those parts of the PSD SIP 
that remain approved after the PSD SIP Narrowing Rule. Thus, the GHG 
PSD permitting requirements included in the 2006 PM2.5 NAAQS 
infrastructure SIP submittals from Ohio and Wisconsin consist of only 
those portions of their PSD SIP programs that apply PSD permitting 
requirements to GHG emissions at or above Tailoring Rule thresholds. 
Therefore, EPA proposes that the GHG PSD permitting program in Ohio and 
Wisconsin have met this set of requirements of sections 110(a)(2)(C) 
and (E) for the 2006 PM2.5 NAAQS.
    EPA reiterates that minor NSR regulations and NSR reform 
regulations are not in the scope of infrastructure SIP actions. 
Therefore, we are not proposing to approve or disapprove existing minor 
NSR regulations or NSR reform regulations for each of the Region 5 
States' 2006 PM2.5 NAAQS infrastructure SIP. Furthermore, 
various sub-elements in this section overlap with elements of 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 significantly to nonattainment, or interfering with 
maintenance, of the NAAQS in another state. Furthermore, section 
110(a)(2)(D)(i)(II) requires SIPs to include provisions prohibiting any

[[Page 46000]]

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 this notice, we are not proposing to act on the portions of any 
state submittal intended to address the interstate transport 
requirements of section 110(a)(2)(D)(i)(I). We previously disapproved 
those portions of the SIP submittals from Indiana and Ohio (see 76 FR 
43175), and today's action neither proposes to approve nor proposes to 
disapprove those portions of the SIP submittals from Illinois, 
Michigan, Minnesota, and Wisconsin. EPA intends to take separate action 
on the section 110(a)(2)(D)(i)(I) portion of the SIP submittals from 
Illinois, Michigan, Minnesota, and Wisconsin. Neither Indiana nor Ohio 
has a 110(a)(2)(D)(i)(I) SIP submittal pending before the Agency at 
this time.
    With respect to the PSD requirements of section 
110(a)(2)(D)(i)(II), EPA notes that each Region 5 State's satisfaction 
of the applicable infrastructure SIP PSD requirements for the 2006 
PM2.5 NAAQS has been detailed in the section addressing 
section 110(a)(2)(C). EPA 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.
    Although Illinois and Minnesota have not adopted or submitted 
regulations for PSD, Federally promulgated rules for this purpose are 
in effect in each of the States, promulgated at 40 CFR 52.21. EPA has 
currently delegated the authority to implement these regulations to 
Illinois and Minnesota. The PSD regulations in question include: (i) 
The explicit identification of SO2 and NOX as 
PM2.5 precursors (and the significant emissions rates for 
direct PM2.5, and SO2 and NOX as its 
precursors), consistent with the requirements of the 2008 NSR Rule; 
(ii) the regulation of PM2.5 and PM10 
condensables consistent with the requirements of the 2008 NSR Rule; 
(iii) the explicit identification of NOX as a precursor to 
ozone consistent with the Phase 2 Rule; and, (iv) permitting of GHG 
emitting sources at the Federal Tailoring Rule thresholds. EPA 
acknowledges that the States have not satisfied the requirement for a 
SIP submission, which results in a proposed disapproval with respect to 
this set of infrastructure SIP requirements of section 
110(a)(2)(D)(i)(II). However, Illinois and Minnesota have no further 
obligations to EPA because both States administer the Federally 
promulgated PSD regulations.
    EPA is proposing to approve revisions to Indiana's PSD SIP that 
identify SO2 and NOX as PM2.5 
precursors, along with the significant emissions rates for direct 
PM2.5 and SO2 and NOX as its 
precursors, consistent with the requirements of the 2008 NSR Rule. We 
are also proposing to approve revisions to Indiana's SIP that regulate 
PM2.5 and PM10 condensables, consistent with the 
requirements of the 2008 NSR Rule. Lastly, EPA is proposing to approve 
revisions to Indiana's SIP that explicitly identify NOX as a 
precursor to ozone, consistent with the requirements of the Phase 2 
Rule. EPA approved revisions to Indiana's SIP on September 28, 2011, 
that incorporate the Federal thresholds for GHG emitting sources for 
PSD permitting. Therefore, EPA proposes that Indiana has met all of the 
infrastructure SIP requirements for PSD associated with section 
110(a)(2)(D)(i)(II) for the 2006 PM2.5 NAAQS.
    EPA is proposing to disapprove the portions of infrastructure SIP 
submissions from Michigan, Ohio, and Wisconsin regarding 
PM2.5 precursors, and PM2.5 and PM10 
condensables, in each of these States' PSD programs. These States have 
not made revisions to their PSD programs consistent with the 
requirements of the 2008 NSR Rule, and therefore EPA proposes that they 
have not met the infrastructure SIP requirements to identify 
PM2.5 precursors, or regulate PM2.5 and 
PM10 condensables, with respect to the PSD requirements of 
section 110(a)(2)(D)(i)(II).
    EPA is proposing to disapprove the portions of infrastructure SIP 
submissions from Michigan and Ohio regarding the explicit 
identification of NOX as a precursor to ozone in each of 
these States' PSD programs. These States have not made revisions to 
their PSD programs consistent with the requirements of the Phase 2 
Rule, and therefore EPA proposes that they have not met the 
infrastructure SIP requirements to identify NOX as a 
precursor to ozone with respect to the PSD requirements of section 
110(a)(2)(D)(i)(II). As previously noted, EPA has already finalized 
disapproval of portions of Wisconsin's infrastructure SIP with respect 
to this requirement.
    As stated above, EPA approved revisions to Indiana's SIP on 
September 28, 2011, that incorporate the Federal Tailoring Rule 
thresholds for GHG emitting sources. Michigan retains the necessary 
authority, resources, and personnel to permit GHG emitting sources at 
the Federal Tailoring Rule thresholds. Ohio and Wisconsin have the 
necessary authority to permit GHG emitting sources at the Federal 
Tailoring Rule, and both States have transmitted letters to EPA stating 
that their infrastructure SIPs before our review includes only those 
parts of their PSD SIP that remain approved after the PSD SIP Narrowing 
Rule. Thus, the GHG PSD permitting requirements included in the 2006 
PM2.5 NAAQS infrastructure SIP submittals from Ohio and 
Wisconsin consist of only those portions of their PSD SIP programs that 
apply PSD permitting requirements to GHG emissions at or above 
Tailoring Rule thresholds. EPA proposes that the States of Indiana, 
Michigan, Minnesota, and Ohio have met the infrastructure SIP 
requirements for permitting GHG emitting sources at the Federal 
Tailoring Rule thresholds with respect to the PSD requirements of 
section 110(a)(2)(D)(i)(II).
    EPA reiterates once again that minor NSR regulations and NSR reform 
regulations are not in the scope of infrastructure SIP actions. 
Therefore, we are not proposing to approve or disapprove existing minor 
NSR regulations or NSR reform regulations for each of the Region 5 
States' 2006 PM2.5 NAAQS infrastructure SIP.
    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 2009 Memo states that 
these requirements can be satisfied by an approved SIP addressing 
reasonably attributable visibility impairment, if required, and an 
approved SIP addressing regional haze.
    EPA's final approval of Illinois' regional haze plan was published 
on July 6, 2012 (see 76 FR 39943). EPA's final approval of Indiana's 
regional haze plan was published on June 11, 2012 (see 77 FR 34218). 
EPA's final approval of Ohio's regional haze plan was published on July 
2, 2012 (see 77 FR 39177). EPA's final approval of Minnesota's regional 
haze plan was published on June 12, 2012 (see 77 FR 34801). EPA's final 
approval of Wisconsin's regional haze plan was signed by the Regional 
Administrator on June 15, 2012, and is awaiting publication in the 
Federal Register. Therefore, EPA proposes that the States of Illinois, 
Indiana, Ohio, Minnesota, and Wisconsin have met this set of 
infrastructure SIP requirements of section 110(a)(2)(D)(i)(II) for the 
2006 PM2.5 NAAQS. EPA is taking separate action on 
Michigan's regional haze plan, which was submitted on November 5, 2010, 
and is not proposing to approve or disapprove the visibility protection

[[Page 46001]]

and regional haze plan requirements of section 110(a)(2)(D)(i)(II) for 
Michigan in today's action. We will address Michigan's satisfaction of 
the infrastructure SIP requirements related to visibility protection 
and regional haze of section 110(a)(2)(D)(i)(II) after EPA finalizes 
action on the regional haze submission.
    Section 110(a)(2)(D)(ii) requires each SIP to contain adequate 
provisions requiring compliance with the applicable requirements of 
section 126 and section 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.
    While Illinois and Minnesota have not adopted or submitted 
regulations for PSD, Federally promulgated rules for this purpose are 
in effect in each of the States, promulgated at 40 CFR 52.21. EPA has 
currently delegated the authority to implement these regulations to 
Illinois and Minnesota. These Federally promulgated rules contain 
provisions requiring new or modified sources to notify neighboring 
states of potential negative air quality impacts. EPA acknowledges that 
the States have not satisfied the requirement for a SIP submission, 
which results in a proposed disapproval with respect to this set of 
infrastructure SIP requirements of section 110(a)(2)(D)(ii). However, 
Illinois and Minnesota have no further obligations to EPA because both 
States administer the Federally promulgated PSD regulations.
    Indiana, Michigan, Ohio, and Wisconsin have provisions in their 
respective EPA-approved PSD programs requiring new or modified sources 
to notify neighboring states of potential negative air quality impacts. 
The original submissions from Indiana, Michigan, and Wisconsin 
reference each State's PSD program as having adequate provisions to 
meet the requirements of section 126(a). Ohio EPA's June 3, 2011, 
supplemental submission clarifies that provisions in their PSD program 
satisfy the requirements of section 126(a). EPA is proposing that 
Indiana, Michigan, Ohio, and Wisconsin have met the infrastructure SIP 
requirements of section 126(a) with respect to the 2006 
PM2.5 NAAQS. None of the Region 5 States have obligations 
under any other section of section 126.
    The original submissions from Indiana, Michigan, Minnesota, and 
Wisconsin affirm that none of these States have pending obligations 
under section 115, while Illinois EPA's August 25, 2011, and Ohio EPA's 
June 3, 2011, supplemental submissions confirmed the same satisfaction 
of section 115. EPA therefore is proposing that all Region 5 States 
have met the applicable infrastructure SIP requirements of section 
110(a)(2)(D)(ii) related to section 115 of the CAA (international 
pollution abatement).

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
    At the time of their submittal, Illinois EPA cited the most recent 
House Bill and Public Act in the State that provides appropriations for 
the Illinois Bureau of Air Programs and associated personnel. In 
addition to the environmental performance partnership agreement (EnPPA) 
with EPA, Illinois has confirmed that it retains all necessary 
resources to carry out required air programs. As discussed in previous 
sections, Illinois EPA has affirmed that 415 ILCS 5/4 and 415 ILCS 5/10 
provide the Director, in conjunction with IPCB, with the authority to 
develop rules and regulations necessary to meet ambient air quality 
standards and respond to any EPA findings of inadequacy with the 
Illinois SIP program. Lastly, IPCB ensures compliance with required 
laws or elements of the State's attainment plan that are necessary to 
attain the NAAQS, or that are necessary to comply with the requirements 
of the CAA. EPA proposes that Illinois has met the infrastructure SIP 
requirements of this portion of section 110(a)(2)(E) with respect to 
the 2006 PM2.5 NAAQS.
    Indiana's biennial budget and their EnPPA with EPA document funding 
and personnel levels for IDEM every two years. As discussed in earlier 
sections, IC 13-14-1-12 provides the Commissioner of IDEM with the 
authority to enforce air pollution control laws. Furthermore, IC 13-14-
8, IC 13-17-3-11, and IC 13-17-3-14 contain the authority for IDEM to 
adopt air emissions standards and compliance schedules. EPA proposes 
that Indiana has met the infrastructure SIP requirements of this 
portion of section 110(a)(2)(E) with respect to the 2006 
PM2.5 NAAQS.
    Michigan's budget ensures that EPA grant funds as well as State 
funding appropriations are sufficient to administer its air quality 
management program, and MDEQ has routinely demonstrated that it retains 
adequate personnel to carry out the duties of this program. Michigan's 
EnPPA with EPA documents certain funding and personnel levels for MDEQ. 
Furthermore, Act 451 provides the legal authority under State law to 
carry out the Michigan SIP. EPA proposes that Michigan has met the 
infrastructure SIP requirements of section 110(a)(2)(E) with respect to 
the 2006 PM2.5 NAAQS.
    Minnesota provided information on the State's authorized spending 
by program, program priorities, and the State budget. MPCA's EnPPA with 
EPA provides the MPCA's assurances of resources to carry out certain 
air programs. EPA also notes that Minnesota Statute chapter 116.07 
provides the legal authority under State law to carry out the SIP. EPA 
proposes that Minnesota has met the infrastructure SIP requirements of 
section 110(a)(2)(E) with respect to the 2006 PM2.5 NAAQS.
    Ohio EPA has included its most recent biennial budget with its 
submittal, which details the funding sources and program priorities 
addressing the required SIP programs. Ohio EPA has routinely 
demonstrated that it retains adequate personnel to administer its air 
quality management program. Ohio's EnPPA with EPA documents certain 
funding and personnel levels at Ohio EPA. As discussed in previous 
sections, ORC 3704.03 provides the legal authority under State law to 
carry out the SIP. EPA proposes that Ohio has met the infrastructure 
SIP requirements of section 110(a)(2)(E) with respect to the 2006 
PM2.5 NAAQS.
    Wisconsin's biennial budget ensures that EPA grant funds as well as 
State funding appropriations are sufficient to administer its air 
quality management program, and WDNR has routinely demonstrated that it 
retains adequate personnel to administer its air quality management 
program. Wisconsin's EnPPA with EPA documents certain funding and 
personnel levels at WDNR. As discussed in previous sections, basic 
duties and authorities in the State are outlined in WS chapter 285.11. 
EPA proposes that Wisconsin has met the

[[Page 46002]]

infrastructure SIP requirements of section 110(a)(2)(E) with respect to 
the 2006 PM2.5 NAAQS.
    As noted above in the discussion addressing section 110(a)(2)(C), 
the resources needed to permit all sources emitting more than 100 tpy 
or 250 tpy (as applicable) of GHG would require more resources than any 
Region 5 State appears to have. This is not a concern in Illinois and 
Minnesota, because PSD permitting for GHGs is based on Federally 
promulgated PSD rules that ``tailor'' the applicability to 75,000 tons 
per year (expressed as carbon dioxide equivalent).
    Given the effect of EPA's Narrowing Rule to provide that approved 
SIPs for Ohio and Wisconsin do not involve permitting GHG sources 
smaller than the Tailoring Rule thresholds, EPA proposes that these 
States also have the resources necessary to implement the requirements 
of their respective SIPs.
    As previously discussed, EPA approved revisions to Indiana's PSD 
program adopting the Federal Tailoring Rule thresholds for GHG on 
September 28, 2011. Therefore, Indiana's SIP as it relates to GHG-
emitting sources for PSD does not involve permitting sources smaller 
than the Tailoring Rule thresholds, and EPA proposes that Indiana 
retains the resources necessary to implement the requirements of its 
SIP.
    EPA confirms that Michigan's PSD regulations provide the State with 
adequate resources to permit GHG consistent with the Tailoring Rule 
thresholds; therefore, EPA proposes that Michigan retains all the 
resources necessary to implement the requirements of its SIP.
Sub-Element 2: State Board Requirements Under Section 128 of the CAA
    Section 110(a)(2)(E) also requires each SIP to contain provisions 
that respect the state board requirements of section 128, which has 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.
    In today's action, EPA is neither proposing to approve or 
disapprove each Region 5 State's satisfaction of the state board 
requirements of section 110(a)(2)(E)(ii). Instead, EPA will take 
separate action on compliance with section 110(a)(2)(E)(ii) for the 
States of Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin 
at a later time. EPA is working with each of the Region 5 States to 
address these requirements in the most appropriate way.

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.
    Illinois EPA requires regulated sources to submit various reports, 
dependent on applicable requirements and the type of permit issued to 
the source. These reports are submitted to the Bureau of Air's 
Compliance Unit for review, and all reasonable efforts are made by 
Illinois EPA to maximize the effectiveness of available resources to 
review the required reports. EPA proposes that Illinois has satisfied 
the infrastructure SIP requirements of section 110(a)(2)(F) with 
respect to the 2006 PM2.5 NAAQS.
    The Indiana State rules for monitoring requirements are contained 
in 326 IAC 3. Additional emissions reporting requirements are found in 
326 IAC 2-6. Emission reports are available upon request by EPA or 
other interested parties. EPA proposes that Indiana has satisfied the 
infrastructure SIP requirements of section 110(a)(2)(F) with respect to 
the 2006 PM2.5 NAAQS.
    Michigan Administrative Code (MAC) R336.2001 to R336.2004 provide 
requirements for performance testing and sampling. MAC R336.2101 to 
R336.2199 provide requirements for continuous emission monitoring, and 
MAC R336.201 and R336.202 require annual reporting of emissions. EPA 
proposes that Michigan has met the infrastructure SIP requirements of 
section 110(a)(2)(F) with respect to the 2006 PM2.5 NAAQS.
    Under Minnesota State air quality rules, any NAAQS is an applicable 
requirement for stationary sources. Minnesota's monitoring rules have 
been previously approved by EPA and are contained in Chapter 7011 of 
Minnesota's SIP. Minnesota Statute chapter 116.07 gives MPCA the 
authority to require owners or operators of emission facilities to 
install and operate monitoring equipment, while Chapter 7007.0800 of 
Minnesota's SIP sets forth the minimum monitoring requirements that 
must be included in stationary source permits. Lastly, Chapter 7017 of 
Minnesota's SIP contains monitoring and testing requirements, including 
rules for continuous monitoring. EPA proposes that Minnesota has met 
the infrastructure SIP requirements of section 110(a)(2)(F) with 
respect to the 2006 PM2.5 NAAQS.
    Ohio EPA district offices and local air agencies are currently 
required to witness 50% of all source testing and review 100% of all 
tests. EPA recognizes that Ohio has routinely submitted quality assured 
analyses and data for publication. Furthermore, requirements for 
continuous emissions monitoring under 40 CFR part 51, appendix P are 
contained in OAC 3745-17-03(c). EPA proposes that Ohio has met the 
infrastructure SIP requirements of section 110(a)(2)(F) with respect to 
the 2006 PM2.5 NAAQS.
    Wisconsin DNR requires regulated sources to submit various reports, 
dependent on applicable requirements and the type of permit issued, to 
the Bureau of Air Management Compliance Team. The frequency and 
requirements for report review are incorporated as part of Wisconsin 
Administrative Code NR 438 and Wisconsin Administrative Code NR 439. 
Additionally, WDNR routinely submits quality assured analyses and data 
obtained from its stationary source monitoring system for review and 
publication. Basic authority for Wisconsin's Federally mandated 
Compliance Assurance Monitoring reporting structure is provided in 
Wisconsin Statute Chapter 285.65. EPA proposes that Wisconsin has met 
the infrastructure SIP requirements of section 110(a)(2)(F) with 
respect to the 2006 PM2.5 NAAQS.

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

    EPA is currently in the process of promulgating new guidance 
providing values that we would recommend for defining emergency 
episodes for PM2.5. Subsequent to the December 2007 
submittals, EPA has provided guidance regarding PM2.5 
emergency episode planning. This guidance was provided in Attachment B 
of a memorandum dated September 25, 2009, from the

[[Page 46003]]

Director of the Air Quality Policy Division to the Regional Air 
Division Directors. In accordance with this guidance, EPA believes that 
all states must have general emergency authority comparable to section 
303 of the CAA. With respect to contingency plans, EPA believes that 
where a state can demonstrate that PM2.5 levels have 
consistently remained below 140.4 micrograms per cubic meter ([micro]g/
m\3\), the state may satisfy section 110(a)(2)(G) without necessarily 
providing for specific emergency episode plans or contingency measures 
for 2006 PM2.5 NAAQS.
    On June 27, 2012, Illinois EPA confirmed that all monitored values 
of PM2.5 have been well below 140.4 [micro]g/m\3\ at all 
monitoring sites in Illinois, and therefore Illinois does not need to 
submit an emergency episode plan and contingency measures for 
PM2.5 at this time. Illinois also has the necessary general 
authority to address emergency episodes, and these provisions are 
contained in 415 ILCS 5/34 and 415 ILCS 5/43(a). EPA proposes that 
Illinois has met the infrastructure SIP requirements of section 
110(a)(2)(G) with respect to the 2006 PM2.5 NAAQS.
    On June 25, 2012, IDEM confirmed that all monitored values of 
PM2.5 have been well below 140.4 [micro]g/m\3\ at all 
monitoring sites in Indiana since 1999, and therefore Indiana does not 
need to submit an emergency episode plan and contingency measures for 
PM2.5 at this time. Several statutory provisions in the 
Indiana Code and the IAC provide the proper mechanisms to address air 
pollution emergency episodes. EPA proposes that Indiana has met the 
infrastructure SIP requirements of section 110(a)(2)(G) with respect to 
the 2006 PM2.5 NAAQS.
    On July 9, 2012, MDEQ confirmed that all monitored PM2.5 
values in Michigan have been well below 140.4 [micro]g/m\3\, therefore, 
MDEQ does not need to submit an emergency episode plan and contingency 
measures for PM2.5 at this time. Michigan R 324.5518 of Act 
451 provides MDEQ with the authority to require the immediate 
discontinuation of air contaminant discharges that constitute an 
imminent and substantial endangerment to the public health, safety, or 
welfare, or to the environment. Furthermore, R 324.5530 of Act 451 
provides for civil action by the Michigan Attorney General for 
violations described in R 324.5518. EPA proposes that Michigan has met 
the infrastructure SIP requirements of section 110(a)(2)(G) with 
respect to the 2006 PM2.5 NAAQS.
    On June 27, 2012, MPCA observed that all monitored values of 
PM2.5 have been well below 140.4 [micro]g/m\3\ at all 
monitoring sites in Minnesota since 2006. Therefore, Minnesota does not 
need to submit an emergency episode plan and contingency measures for 
PM2.5 at this time. Chapter 7000.5000 and 7009.1050 of the 
Minnesota SIP contain the emergency powers set forth in the State. 
Chapter 7009.1000-7009.1110 of Minnesota SIP contain the provisions 
necessary for determining air quality emergency episodes. EPA proposes 
that Minnesota has met the infrastructure SIP requirements of section 
110(a)(2)(G) with respect to the 2006 PM2.5 NAAQS.
    On July 5, 2012, Ohio EPA confirmed that all monitored values of 
PM2.5 have been well below 140.4 [micro]g/m\3\ at all 
monitoring sites in Ohio, and therefore Ohio does not need to submit an 
emergency episode plan and contingency measures for PM2.5 at 
this time. OAC 3745-25 provides the requirement to implement emergency 
action plans in the event of an Air Quality Alert or higher. EPA 
proposes that Ohio has met the infrastructure SIP requirements of 
section 110(a)(2)(G) with respect to the 2006 PM2.5 NAAQS.
    On July 2, 2012, WDNR confirmed that that all monitored values of 
PM2.5 have been well below 140.4 [micro]g/m\3\ at all 
monitoring sites in Wisconsin, and therefore Wisconsin does not need to 
submit an emergency episode plan and contingency measures for 
PM2.5 at this time. WS chapter 285.85 provides the 
requirement for WDNR to act upon a finding that episode or emergency 
conditions exist. EPA proposes that Wisconsin has met the 
infrastructure SIP requirements of section 110(a)(2)(G) with respect to 
the 2006 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.
    As previously mentioned, 415 ILCS \5/4\ and 415 ILCS \5/10\ provide 
the Director of Illinois EPA, in conjunction with IPCB, with the 
authority to develop rules and regulations necessary to meet ambient 
air quality standards. Furthermore, they have the authority to respond 
to any EPA findings of inadequacy with the Illinois SIP program. EPA 
proposes that Illinois has met the infrastructure SIP requirements of 
section 110(a)(2)(H) with respect to the 2006 p.m.2.5 NAAQS.
    IDEM continues to update and implement needed revisions to 
Indiana's SIP as necessary to meet ambient air quality standards. As 
discussed in previous sections, authority to adopt emissions standards 
and compliance schedules is found at IC 13-4-8, IC 13-17-3-4, IC 13-17-
3-11, and IC 13-17-3-14. EPA proposes that Indiana has met the 
infrastructure SIP requirements of section 110(a)(2)(H) with respect to 
the 2006 p.m.2.5 NAAQS.
    Michigan Act 451 324.5503 and 324.5512 provides the authority to: 
promulgate rules to establish standards for ambient air quality and 
emissions; issue, deny, revoke, or reissue permits; make findings of 
fact and determinations; make, modify, or cancel orders that require 
the control of air pollution and/or permits rules and regulations 
necessary to meet NAAQS; and prepare and develop a general 
comprehensive plan for the control or abatement of existing air 
pollution and for control or prevention of any new air pollution. EPA 
proposes that Michigan has met the infrastructure SIP requirements of 
section 110(a)(2)(H) with respect to 2006 p.m.2.5 NAAQS.
    Minnesota Statute chapter 116.07 grants the agency the authority to 
``[a]dopt, amend, and rescind rules and standards having the force of 
law relating to any purpose * * * for the prevention, abatement, or 
control of air pollution.'' EPA proposes that Minnesota has met the 
infrastructure SIP requirements of section 110(a)(2)(H) with respect to 
the 2006 p.m.2.5 NAAQS.
    ORC 3704.03 provides the Director of Ohio EPA with the authority to 
develop rules and regulations necessary to meet ambient air quality 
standards. EPA proposes that Ohio has met the infrastructure SIP 
requirements of section 110(a)(2)(H) with respect to the 2006 
p.m.2.5 NAAQS.
    WS chapter 285.11(6) provides WDNR with the authority to develop 
all rules, limits, and regulations necessary to meet the NAAQS as they 
evolve, and to respond to any EPA findings of inadequacy with the 
overall Wisconsin SIP and air management programs. EPA proposes that 
Wisconsin has met the infrastructure SIP requirements of section 
110(a)(2)(H) with respect to the 2006 p.m.2.5 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

[[Page 46004]]

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 Region 5 States' certifications addressing 
the requirements of section 110(a)(2)(J) are 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. All EPA Region 5 States consult with 
appropriate governments, stakeholders, and FLM in their planning 
efforts.
    Illinois EPA is required to give notice to the Office of the 
Attorney General and the Illinois Department of Natural Resources 
during the rulemaking process. Furthermore, Illinois provides notice to 
reasonably anticipated stakeholders and interested parties, as well as 
to any FLM if the rulemaking applies to Federal land which the FLM has 
authority over. Additionally, Illinois EPA participates in the Lake 
Michigan Air Director's Consortium (LADCO), which consists of 
collaboration with the States of Indiana, Wisconsin, Michigan, and 
Ohio. Lastly, Illinois EPA participates in the Regional Haze Planning 
Process through its membership in the Midwest Regional Planning 
Organization. EPA proposes that Illinois has met the infrastructure SIP 
requirements of this portion of section 110(a)(2)(J) with respect to 
the 2006 p.m.2.5 NAAQS.
    IDEM actively participates in the regional planning efforts that 
include State rule developers, representatives from the FLMs, and other 
affected stakeholders. Additionally, Indiana is an active member of 
LADCO. EPA proposes that Indiana has met the infrastructure SIP 
requirements of this portion of section 110(a)(2)(J) with respect to 
the 2006 p.m.2.5 NAAQS.
    MDEQ actively participates in planning efforts that include 
stakeholders from local governments, the business community, and 
community activist groups. MDEQ also routinely involves FLMs and Tribal 
groups in Michigan SIP development. Michigan is also an active member 
of LADCO. Therefore, EPA proposes that Michigan has met the 
infrastructure SIP requirements of this portion of section 110(a)(2)(J) 
with respect to the 2006 p.m.2.5 NAAQS.
    MPCA actively participates in the Central Regional Air Planning 
Association as well as the Central States Air Resource Agencies. MPCA 
has historically participated in LADCO, and is in the process of 
becoming a full-time member of the organization. MPCA has also 
demonstrated that it frequently consults and discusses issues with 
pertinent Tribes. Therefore, EPA proposes that Minnesota has met the 
infrastructure SIP requirements of this portion of section 110(a)(2)(J) 
with respect to the 2006 p.m.2.5 NAAQS.
    Ohio EPA actively participates in the regional planning efforts 
that include both the State rule developers as well as representatives 
from the FLMs and other affected stakeholders. The FLMs are also 
included in Ohio EPA's interested party lists which provide 
announcements of draft and proposed rule packages. Additionally, Ohio 
is an active member of LADCO. Therefore, EPA proposes that Ohio has met 
the infrastructure SIP requirements of this portion of section 
110(a)(2)(J) with respect to the 2006 p.m.2.5 NAAQS.
    WS chapter 285.13(5) contains the provisions for WDNR to advise, 
consult, contract, and cooperate with other agencies of the State and 
local governments, industries, other states, interstate or inter-local 
agencies, the Federal government, and interested persons or groups 
during the entire process of SIP revision development and 
implementation and for other elements regarding air management for 
which the agency is the officially charged agency. WDNR's Bureau of Air 
Management has effectively used formal stakeholder structures in the 
development and refinement of all SIP revisions. Additionally, 
Wisconsin is an active member of LADCO. EPA proposes that Wisconsin has 
satisfied the infrastructure SIP requirements of this portion of 
section 110(a)(2)(J) with respect to the 2006 p.m.2.5 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.
    Illinois EPA continues to collaborate with the Cook County 
Department of Environmental Control. This consists of: continued and 
routine monitoring of air quality throughout the State, and notifying 
the public when unhealthy air quality is measured or forecasted. 
Illinois EPA provides air quality data to EPA's AIRNOW program, and 
also provides the daily air quality index (AQI) to the media. 
Additionally, Illinois EPA provides the AQI to local stakeholder groups 
including Partners for Clean Air in Chicago and the Clean Air 
Partnership in St. Louis. Lastly, air quality data, as well as measures 
that can be taken to prevent exceedances, are available on Illinois 
EPA's Web site. EPA proposes that Illinois has met the infrastructure 
SIP requirements of this portion of section 110(a)(2)(J) with respect 
to the 2006 p.m.2.5 NAAQS.
    IDEM monitors air quality data daily, and reports the AQI to the 
interested public and media if necessary. IDEM also participates and 
submits information to EPA's AIRNOW program, and maintains SmogWatch, 
which is an informational tool created by IDEM to share air quality 
forecasts for each day. SmogWatch provides daily information about 
ground-level ozone, particulate matter concentration levels, health 
information, and monitoring data for seven regions in Indiana. EPA 
proposes that Indiana has met the infrastructure SIP requirements of 
this portion of section 110(a)(2)(J) with respect to the 2006 
p.m.2.5 NAAQS.
    MDEQ actively participates in programs such as Ozone Action, 
AIRNOW, and EnviroFlash. Additionally, MDEQ posts current air quality 
concentrations on the its web pages, and prepares an annual air quality 
report. EPA proposes that Michigan has met the infrastructure SIP 
requirements of this portion of section 110(a)(2)(J) with respect to 
the 2006 p.m.2.5 NAAQS.
    Minnesota consistently notifies the public when exceedances occur, 
participates in the AIRNOW program, and dedicates portions of the MPCA 
Web site to enhancing public awareness of measures that can be taken to 
prevent exceedances. EPA proposes that Minnesota has met the 
infrastructure SIP requirements of this portion of section 110(a)(2)(J) 
with respect to the 2006 p.m.2.5 NAAQS.
    Ohio EPA's district offices and local air agencies monitor air 
quality daily, and where required, report the daily AQI to the 
interested media. In addition, Ohio EPA's remote access of data system 
provides online reports of real time air quality data on the internet 
and feeds raw information to EPA's AIRNOW program. Furthermore, Ohio 
EPA actively involves local stakeholder groups in the AIRNOW forecast 
program. EPA proposes that Ohio has met the infrastructure SIP 
requirements of this portion of section 110(a)(2)(J) with respect to 
the 2006 p.m.2.5 NAAQS.
    In addition to maintaining an active monitoring network for 
multiple criteria pollutants (with NAAQS), WDNR also routinely 
forecasts air quality when elevated pollutant concentrations are

[[Page 46005]]

noted. Public notice is provided at levels associated with the extent 
of the monitored problems ranging from a simple advisory to alert 
levels, consistent with the provisions of WS chapter 285.11. Wisconsin 
also participates in the AIRNOW program, and dedicates portions of the 
WDNR Web site to enhancing public awareness of measures that can be 
taken to prevent exceedances. EPA proposes that Wisconsin has met the 
infrastructure SIP requirements of this portion of section 110(a)(2)(J) 
with respect to the 2006 ozone and PM2.5 NAAQS.
Sub-Element 3: PSD
    States must meet applicable requirements of section 110(a)(2)(C) 
related to PSD. All six Region 5 States have stated their commitment to 
addressing both long-term requirements to meet natural visibility 
levels by 2064 as well as concurrent review of new major sources and 
major modifications under each State's approved PSD NSR program. Each 
Region 5 State'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). Our proposed actions are 
reiterated below.
    Although Illinois and Minnesota have not adopted or submitted 
regulations for PSD, Federally promulgated rules for this purpose are 
in effect in each of the States, promulgated at 40 CFR 52.21. EPA has 
currently delegated the authority to implement these regulations to 
Illinois and Minnesota. The PSD regulations in question include: (i) 
The explicit identification of SO2 and NOX as 
PM2.5 precursors (and the significant emissions rates for 
direct PM2.5, and SO2 and NOX as its 
precursors) consistent with the requirements of the 2008 NSR Rule; (ii) 
the regulation of PM2.5 and PM10 condensables 
consistent with the requirements of the 2008 NSR Rule; (iii) the 
explicit identification of NOX as a precursor to ozone 
consistent with the Phase 2 Rule; and, (iv) permitting of GHG emitting 
sources at the Federal Tailoring Rule thresholds. EPA acknowledges that 
the States have not satisfied the requirement for a SIP submission, 
which results in a proposed disapproval with respect to this set of 
infrastructure SIP requirements of section 110(a)(2)(D)(J). However, 
Illinois and Minnesota have no further obligations to EPA because both 
States administer the Federally promulgated PSD regulations.
    EPA is proposing to approve revisions to Indiana's PSD SIP that 
identify SO2 and NOX as PM2.5 
precursors, along with the significant emissions rates for direct 
PM2.5, and SO2 and NOX as its 
precursors, consistent with the requirements of the 2008 NSR Rule. We 
are also proposing to approve revisions to Indiana's SIP that regulate 
PM2.5 and PM10 condensables, consistent with the 
requirements of the 2008 NSR Rule. Lastly, EPA is proposing to approve 
revisions to Indiana's SIP that explicitly identify NOX as a 
precursor to ozone, consistent with the requirements of the Phase 2 
Rule. EPA approved revisions to Indiana's SIP on September 28, 2011, 
that incorporate the Federal thresholds for GHG emitting sources for 
PSD permitting. Therefore, EPA proposes that Indiana has met all of the 
infrastructure SIP requirements for PSD associated with section 
110(a)(2)(D)(J) for the 2006 p.m.2.5 NAAQS.
    EPA is proposing to disapprove the portions of infrastructure SIP 
submissions from Michigan, Ohio, and Wisconsin regarding 
PM2.5 precursors, and PM2.5 and PM10 
condensables, in each of these States' PSD programs. These States have 
not made revisions to their PSD programs consistent with the 
requirements of the 2008 NSR Rule, and therefore EPA proposes that they 
have not met the infrastructure SIP requirements to identify 
PM2.5 precursors, or regulate PM2.5 and 
PM10 condensables, with respect to the PSD requirements of 
section 110(a)(2)(J).
    EPA is proposing to disapprove the portions of infrastructure SIP 
submissions from Michigan and Ohio regarding the explicit 
identification of NOX as a precursor to ozone in each of 
these States' PSD programs. These States have not made revisions to 
their PSD programs consistent with the requirements of the Phase 2 
Rule, and therefore EPA proposes that they have not met the 
infrastructure SIP requirements to identify NOX as a 
precursor to ozone with respect to the PSD requirements of section 
110(a)(2)(J). As previously noted, EPA has already finalized 
disapproval of portions of Wisconsin's infrastructure SIP with respect 
to this requirement.
    As stated above, EPA approved revisions to Indiana's SIP on 
September 28, 2011, that incorporate the Federal Tailoring Rule 
thresholds for GHG emitting sources. Michigan retains the necessary 
authority, resources, and personnel to permit GHG emitting sources at 
the Federal Tailoring Rule thresholds. Ohio and Wisconsin have the 
necessary authority to permit GHG emitting sources at the Federal 
Tailoring Rule, and both States have transmitted letters to EPA stating 
that their infrastructure SIPs before our review includes only those 
parts of their PSD SIP that remain approved after the PSD SIP Narrowing 
Rule. Thus, the GHG PSD permitting requirements included in the 2006 
PM2.5 NAAQS infrastructure SIP submittals from Ohio and 
Wisconsin consist of only those portions of their PSD SIP programs that 
apply PSD permitting requirements to GHG emissions at or above 
Tailoring Rule thresholds. EPA proposes that the States of Indiana, 
Michigan, Minnesota, and Ohio have met the infrastructure SIP 
requirements for permitting GHG emitting sources at the Federal 
Tailoring Rule thresholds with respect to the PSD requirements of 
section 110(a)(2)(D)(J).
    EPA reiterates once again that minor NSR regulations and NSR reform 
regulations are not in the scope of infrastructure SIP actions. 
Therefore, we are not proposing to approve or disapprove existing minor 
NSR regulations or NSR reform regulations for each of the Region 5 
States' 2006 PM2.5 NAAQS infrastructure SIP.
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. This would be the case even in the event a secondary 
PM2.5 NAAQS for visibility is established, because this 
NAAQS would not affect visibility requirements under part C.
    EPA's final approval of Illinois' regional haze plan was published 
on July 6, 2012 (see 76 FR 39943). EPA's final approval of Indiana's 
regional haze plan was published on June 11, 2012 (see 77 FR 34218). 
EPA's final approval of Ohio's regional haze plan was published on July 
2, 2012 (see 77 FR 39177). EPA's final approval of Minnesota's regional 
haze plan was published on June 12, 2012 (see 77 FR 34801). EPA's final 
approval of Wisconsin's regional haze plan was signed by the Regional 
Administrator on June 15, 2012, and is awaiting publication in the 
Federal Register. Therefore, EPA proposes that the States of Illinois, 
Indiana, Ohio, Minnesota, and Wisconsin have met this set of 
requirements of section 110(a)(2)(J). EPA is taking separate action on 
Michigan's

[[Page 46006]]

regional haze plan, which was submitted on November 5, 2010, and is not 
proposing to approve or disapprove the visibility protection and 
regional haze plan requirements of section 110(a)(2)(J) for Michigan in 
today's action. We will address Michigan's satisfaction of the 
infrastructure SIP requirements related to visibility protection and 
regional haze of section 110(a)(2)(J) after EPA finalizes action on the 
regional haze submission.

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 from any NAAQS pollutant 
and submission of such data to EPA upon request.
    Illinois EPA maintains the capability to perform modeling of the 
air quality impacts of emissions of all criteria pollutants, including 
the capability to use complex photochemical grid models. This modeling 
is used in support of the SIP for all nonattainment areas in the State. 
Illinois EPA also requires air quality modeling in support of 
permitting the construction of major and some minor new sources under 
the PSD program. These modeling data are available to EPA as well as 
the public upon request. Lastly, Illinois EPA participates in LADCO, 
which conducts regional modeling that is used for statewide planning 
purposes. EPA proposes that Illinois EPA has met the infrastructure SIP 
requirements of section 110(a)(2)(K) with respect to the 2006 
PM2.5 NAAQS.
    IDEM continues to review the potential impact of major and some 
minor new sources using computer models. Indiana's rules regarding air 
quality modeling are contained in 326 IAC 2-2-4, 326 IAC 2-2-5, 326 IAC 
2-2-6, and 326 IAC 2-2-7. These modeling data are available to EPA or 
other interested parties upon request. EPA proposes that Indiana has 
met the infrastructure SIP requirements of section 110(a)(2)(K) with 
respect to the 2006 PM2.5 NAAQS.
    MDEQ reviews the potential impact of major and some minor new 
sources, consistent with 40 CFR part 51, appendix W, ``Guidelines on 
Air Quality Models.'' These modeling data are available to EPA upon 
request. EPA proposes that Michigan has met the infrastructure SIP 
requirements of section 110(a)(2)(K) with respect to the 2006 
PM2.5 NAAQS.
    MPCA reviews the potential impact of major and some minor new 
sources. Applicable major sources in Minnesota are required to perform 
modeling to show that emissions do not cause or contribute to a 
violation of any NAAQS. Furthermore, MPCA maintains the capability to 
perform its own modeling. Because Minnesota administers the Federally 
promulgated PSD regulations, pre-construction permitting modeling is 
conducted in compliance with EPA's regulations. EPA proposes that 
Minnesota has met the infrastructure SIP requirements of section 
110(a)(2)(K) with respect to the 2006 PM2.5 NAAQS.
    Ohio EPA reviews the potential impact of major and some minor new 
sources, consistent with 40 CFR part 51, appendix W, ``Guidelines on 
Air Quality Models,'' as well as Ohio EPA Engineering Guide 69. These 
modeling data are available to EPA upon request. EPA proposes that Ohio 
has met the infrastructure SIP requirements of section 110(a)(2)(K) 
with respect to the 2006 PM2.5 NAAQS.
    WDNR maintains the capability to perform computer modeling of the 
air quality impacts of emissions of all criteria pollutants, including 
both source-oriented and more regionally directed complex photochemical 
grid models. WDNR collaborates with LADCO, EPA, and other Lake Michigan 
States in order to perform modeling. The authorities to perform 
modeling in Wisconsin reside in WS chapter 285.11, WS chapter 285.13, 
and WS chapter 285.60--285.69. EPA proposes that Wisconsin has met the 
infrastructure SIP requirements of section 110(a)(2)(K) with respect to 
the 2006 PM2.5 NAAQS.

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

    This section requires SIPs to mandate each major stationary source 
to pay permitting fees to cover the cost of reviewing, approving, 
implementing, and enforcing a permit.
    Illinois EPA implements and operates the title V permit program, 
which EPA approved on December 4, 2001 (66 FR 62946); therefore, EPA 
proposes that Illinois has met the infrastructure SIP requirements of 
section 110(a)(2)(L).
    IDEM implements and operates the title V permit program, which EPA 
approved on December 4, 2001 (66 FR 62969); revisions to program were 
approved on August 13, 2002 (67 FR 52615). EPA proposes that Indiana 
has met the infrastructure SIP requirements of section 110(a)(2)(L).
    MDEQ implements and operates the title V permit program, which EPA 
approved on December 4, 2001 (66 FR 62949); revisions to the program 
were approved on November 10, 2003 (68 FR 63735). EPA proposes that 
Michigan has met the infrastructure SIP requirements of section 
110(a)(2)(L).
    MPCA implements and operates the title V permit program, which EPA 
approved on December 4, 2001 (66 FR 62967); therefore, EPA proposes 
that Minnesota has met the infrastructure SIP requirements of section 
110(a)(2)(L).
    Ohio EPA implements and operates the title V permit program, which 
EPA approved on August 15, 1995 (60 FR 42045); revisions to the program 
were approved on November 20, 2003 (68 FR 65401). EPA proposes that 
Ohio has met the infrastructure SIP requirements of section 
110(a)(2)(L).
    WDNR implements and operates the title V permit program, which EPA 
approved on December 4, 2001 (66 FR 62951); revisions to the program 
were approved on February 28, 2006 (71 FR 9934). EPA proposes that 
Wisconsin has met the infrastructure SIP requirements of section 
110(a)(2)(L).
    EPA proposes that all Region 5 States have met the infrastructure 
SIP requirements of section 110(a)(2)(L) with respect to 2006 
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.
    All public participation procedures pertaining to Illinois EPA are 
consistent with 35 Illinois Administrative Code Part 164 and Part 252. 
Part 252 is an approved portion of Illinois' SIP. EPA proposes that 
Illinois has met the infrastructure SIP requirements of section 
110(a)(2)(M) with respect to the 2006 PM2.5 NAAQS.
    Any IDEM rulemaking procedure contained in IC 13-14-9 requires 
public participation in the SIP development process. In addition, IDEM 
ensures that the requirements of 40 CFR 51.102 are satisfied during the 
SIP development process. EPA proposes that Indiana has met the 
infrastructure SIP requirements of section 110(a)(2)(M) with respect to 
the 2006 PM2.5 NAAQS.
    In Michigan, memoranda of understanding regarding consultation or 
participation in the SIP development process have been entered between 
MDEQ and local political subdivisions. MDEQ also provides opportunity 
for stakeholder workgroup participation in rule development processes. 
EPA proposes that Michigan has met the infrastructure SIP requirements 
of section 110(a)(2)(M) with respect to the 2006 PM2.5 
NAAQS.
    Minnesota regularly consults with local political subdivisions 
affected by the SIP, where applicable. EPA observes that Minnesota 
Statute chapter 116.05 authorizes cooperation and agreement between 
MPCA and other State and local governments. Additionally, the Minnesota 
Administrative Procedures

[[Page 46007]]

Act (Minnesota Statute chapter 14) provides general notice and comment 
procedures that are followed during SIP development. Lastly, MPCA 
regularly issues public notices on proposed actions. EPA proposes that 
Minnesota has met the infrastructure SIP requirements of section 
110(a)(2)(M) with respect to the 2006 PM2.5 NAAQS.
    Ohio EPA follows approved procedures for allowing public 
participation, consistent with OAC 3745-47, which is part of the 
approved SIP. EPA proposes that Ohio has met the infrastructure SIP 
requirements of section 110(a)(2)(M) with respect to the 2006 
PM2.5 NAAQS.
    In addition to the measures outlined in the paragraph addressing 
WDNR's submittal regarding consultation requirements of section 
110(a)(2)(J), as contained in WS chapter 285.13(5), the State follows a 
formal public hearing process in the development and adoption of all 
SIP revisions that entail new or revised control programs or strategies 
and targets. EPA proposes that Wisconsin has met the infrastructure SIP 
requirements of section 110(a)(2)(M) with respect to the 2006 
PM2.5 NAAQS.

V. What action is EPA taking?

    EPA is proposing to approve some elements and disapprove remaining 
elements of submissions from the EPA Region 5 States certifying that 
the current SIPs are sufficient to meet the required infrastructure 
elements under sections 110(a)(1) and (2) for the 2006 PM2.5 
NAAQS. EPA is also proposing to approve portions of a submittal from 
Indiana intended to meet EPA's requirements for the NSR and PSD program 
in that State. Specifically, they include: (i) 326 IAC 2-1.1-1(2); (ii) 
326 IAC 2-1.1-1(10); (iii) 326 IAC 2-2-1(dd)(1); (iv) 326 IAC 2-2-
1(ff)(7); (v) 326 IAC 2-2-1(ss)(1); (vi) 326 IAC 2-2-1(ww)(1)(F); (vii) 
326 IAC 2-2-1(ww)(1)(G); and, (viii) 326 IAC 2-2-4(b)(2)(vi).
    EPA's proposed actions for each Region 5 State's satisfaction of 
infrastructure SIP requirements, by element of section 110(a)(2) are 
contained in the table below.

----------------------------------------------------------------------------------------------------------------
In the above table, the key is as follows:
A Approve.
NA No Action/Separate Rulemaking.
D Disapprove.
* Federally promulgated rules in place.
** Previously discussed in element (C).

    To clarify, EPA is proposing to disapprove the infrastructure SIP 
submissions from Illinois and Minnesota with respect to certain PSD 
requirements including: (i) The explicit identification of 
SO2 and NOX as PM2.5 precursors (and 
the significant emissions rates for direct PM2.5, and 
SO2 and NOX as its precursors) consistent with 
the requirements of the 2008 NSR Rule; (ii) the regulation of 
PM2.5 and PM10 condensables consistent with the 
requirements of the 2008 NSR Rule; (iii) the explicit identification of 
NOX as a precursor to ozone consistent with the Phase 2 
Rule; and, (iv) permitting of GHG emitting sources at the Federal 
Tailoring Rule thresholds.
    EPA is also proposing to disapprove the infrastructure SIP 
submissions from Illinois and Minnesota with respect to the 
requirements of section 110(a)(2)(D)(ii) related to interstate 
pollution abatement. Specifically, this section requires states with 
PSD programs have provisions requiring a new or modified source to 
notify neighboring states of the potential impacts from the source, 
consistent with the requirements of section 126(a).
    However, Illinois and Minnesota have no further obligations to EPA 
because Federally promulgated rules, promulgated at 40 CFR 52.21 are in 
effect in each of these States. EPA has delegated the authority to 
Illinois and Minnesota to administer these rules, which include 
provisions related to PSD and interstate pollution abatement. A final 
disapproval for Illinois or Minnesota for these infrastructure SIP 
requirements will not result in sanctions under section 179(a), nor 
will it obligate EPA to promulgate a FIP within two years of final 
action if the States do not submit revisions to their PSD SIPs 
addressing these deficiencies. Instead, Illinois and Minnesota are 
already administering the Federally promulgated PSD regulations.

[[Page 46008]]

    The grounds for EPA's proposed disapproval of portions of the 
infrastructure SIP submittals from Ohio, Michigan, and Wisconsin are 
very narrow, and pertain only to these specific deficiencies in the 
States' SIPs described in the relevant sections of this proposed 
action.
    As previously discussed, Michigan and Ohio have been working on 
revisions to their PSD programs, consistent with the requirements of 
the Phase 2 Rule and the 2008 NSR Rule. We will work with the States to 
rectify these issues promptly. In addition, EPA will work with WDNR to 
account for the explicit identification of precursors to 
PM2.5, as well as PM2.5 and PM10 
condensables, in its PSD program.\9\
---------------------------------------------------------------------------

    \9\ Although not specific to this action, EPA will also continue 
to work with WDNR to ensure that revisions to the State's PSD 
program contain provisions that explicitly identify NOX 
as a precursor to ozone, consistent with the Phase 2 Rule.
---------------------------------------------------------------------------

    Under section 179(a) of the CAA, final disapproval of a submission 
that addresses a requirement of a Part D Plan (section 171--section 193 
of the CAA), or is required in response to a finding of substantial 
inadequacy as described in section 110(k)(5) starts a sanction clock. 
The provisions in the submissions we are disapproving were not 
submitted by Michigan, Ohio, or Wisconsin to meet either of those 
requirements. Therefore, if EPA takes final action to disapprove these 
submissions, no sanctions under section 179 will be triggered.
    The full or partial disapproval of a SIP revision triggers the 
requirement under section 110(c) that EPA promulgate a FIP no later 
than two years from the date of the disapproval unless the state 
corrects the deficiency, and the Administrator approves the plan or 
plan revision before the Administrator promulgates such FIP. As 
previously mentioned, EPA anticipates that MDEQ and Ohio EPA will make 
submissions rectifying each of these deficiencies. Further, EPA 
anticipates acting on the submissions within the two year time frame 
prior to our FIP obligation on these very narrow issues. In the 
interim, EPA expects Michigan and Ohio to treat and explicitly identify 
NOX as a precursor to ozone for PSD permitting consistent 
with the requirements of the Phase 2 Rule. EPA also expects these 
States to adhere to the requirements of the 2008 NSR Rule with respect 
to the treatment and identification of PM2.5 precursors and 
the accounting for PM2.5 and PM10 condensables in 
permitting emissions limits in their respective PSD programs.
    EPA will actively work with Wisconsin to incorporate changes to its 
PSD program that explicitly identify PM2.5 precursors and 
account for PM2.5 and PM10 condensables in 
permitting emissions limits, consistent with the 2008 NSR Rule. In the 
interim, EPA expects WDNR to adhere to the associated requirements of 
the 2008 NSR Rule in its PSD program, specifically with respect to the 
explicit identification of PM2.5 precursors, and the 
accounting for PM2.5 and PM10 condensables in 
permitting emissions limits.

VI. 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 Order 
12866 (58 FR 51735, October 4, 1993);
     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 (Pub. L. 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, this rule does not have Tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and EPA notes that it will not impose substantial direct 
costs on Tribal governments or preempt Tribal law.
