ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2011-0888; FRL-9913-59-Region 5]


Approval and Promulgation of Air Quality Implementation Plans; 
Illinois, Michigan, Minnesota, Wisconsin; Infrastructure SIP 
Requirements for the 2008 Lead NAAQS

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final 
action to approve elements of state implementation plan (SIP) 
submissions from Michigan and Wisconsin while taking final action to 
approve some elements and disapprove other elements of SIP submissions 
from Illinois and Minnesota regarding the infrastructure requirements 
of section 110 of the Clean Air Act (CAA) for the 2008 lead National 
Ambient Air Quality Standards (2008 Pb 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. Illinois and Minnesota already 
administer federally promulgated regulations that address the final 
disapprovals described in today's rulemaking. Therefore, these two 
states are not obligated to submit new or additional regulations to 
EPA.

DATES: This final rule is effective on August 15, 2014.

ADDRESSES: EPA has established a docket for this action under Docket ID 
No. EPA-R05-OAR-2011-0888. All documents in the docket are listed in

SUPPLEMENTARY INFORMATION: The proposed rulemaking associated with this 
final action was published on May 13, 2014, and EPA received two 
comment letters during the comment period, which ended on June 12, 
2014. One of the letters supported EPA's proposed actions, and the 
concerns raised in the other letter, as well as EPA's response, will be 
addressed in this final action.
    Throughout this document whenever ``we,'' ``us,'' or ``our'' is 
used, we mean EPA. This supplementary information section is arranged 
as follows:

I. What is the background of these SIP submissions?
    A. What state SIP submissions does this rulemaking address?
    B. Why did the states make these SIP submissions?
    C. What is the scope of this rulemaking?
II. What is our response to comments received on the proposed 
rulemaking?
III. What action is EPA taking?
IV. Statutory and Executive Order Reviews.

I. What is the background of these SIP submissions?

A. What state SIP submissions does this rulemaking address?

    This rulemaking addresses submissions from the following states in 
EPA Region 5: Illinois Environmental Protection Agency (Illinois EPA); 
Michigan Department of Environmental Quality (MDEQ); Minnesota 
Pollution Control Agency (MPCA); and Wisconsin Department of Natural 
Resources (WDNR). The states submitted their 2008 Pb NAAQS 
infrastructure SIPs on the following dates: Illinois--December 31, 
2012; Michigan--April 3, 2012, and supplemented on August 9, 2013, and 
September 19, 2013; Minnesota--June 19, 2012; and, Wisconsin--July 26, 
2012.

B. Why did the states make these SIP submissions?

    Under sections 110(a)(1) and (2) of the CAA, states are required to 
submit infrastructure SIPs to ensure that their SIPs provide for 
implementation, maintenance, and enforcement of the NAAQS, including 
the 2008 Pb 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 Pb and ozone already meet 
those requirements.
    EPA highlighted this statutory requirement in an October 2, 2007, 
guidance document entitled ``Guidance on SIP Elements Required Under 
Sections 110(a)(1) and (2) for the 1997 8-hour Ozone and 
PM2.5 National Ambient Air Quality Standards'' (2007 Memo). 
On September 25, 2009, EPA issued an additional guidance document 
pertaining to the 2006 PM2.5\1\ 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), followed by the October 14, 2011, 
``Guidance on infrastructure SIP Elements Required Under Sections 
110(a)(1) and (2) for the 2008 Lead (Pb) National Ambient Air Quality 
Standards (NAAQS)'' (2011 Memo). Most recently, EPA issued ``Guidance 
on Infrastructure State Implementation Plan (SIP) Elements under Clean 
Air Act Sections 110(a)(1) and (2)'' on September 13, 2013 (2013 Memo). 
The SIP submissions referenced in this rulemaking pertain to the 
applicable requirements of section 110(a)(1) and (2), and primarily 
address the 2008 Pb NAAQS. To the extent that the prevention of 
significant deterioration (PSD) program is comprehensive and non-NAAQS 
specific, a narrow evaluation of other NAAQS, such as the 1997 ozone 
and 2006 PM2.5 NAAQS will be included in the appropriate 
sections.
---------------------------------------------------------------------------

    \1\ PM2.5 refers to particulate matter of 2.5 microns 
or less in diameter, oftentimes referred to as ``fine'' particles.
---------------------------------------------------------------------------

C. What is the scope of this rulemaking?

    EPA is acting upon the SIP submissions from Illinois, Michigan, 
Minnesota, and Wisconsin that address the infrastructure requirements 
of CAA sections 110(a)(1) and 110(a)(2) for the 2008 Pb NAAQS. The 
requirement for states to make a SIP submission of this type arises out 
of CAA section 110(a)(1). Pursuant to section 110(a)(1), states must 
make SIP submissions ``within 3 years (or such shorter period as the 
Administrator may prescribe) after the promulgation of a national 
primary ambient air quality standard (or any revision thereof),'' and 
these SIP submissions are to provide for the ``implementation, 
maintenance, and enforcement'' of such NAAQS. The statute directly 
imposes on states the duty to make these SIP submissions, and the 
requirement to make the

[[Page 41440]]

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

II. What is our response to comments received on the proposed 
rulemaking?

    The public comment period for EPA's proposed actions with respect 
to each state's satisfaction of the infrastructure SIP requirements for 
the 2008 Pb NAAQS closed on June 12, 2014. EPA received two comment 
letters, one of which was in support of our proposed actions. A 
synopsis of the adverse comments contained in the other letter, as well 
as EPA's response, is discussed below.
    Comment: The commenter noted that EPA did not address Wisconsin's 
compliance with the requirements to incorporate PM2.5 
increments \2\ into its SIP. The commenter asserted that because 
Wisconsin has failed to incorporate the increments, EPA needs to 
disapprove the applicable infrastructure SIP PSD sub-element for the 
PM2.5 increments, and begin a Federal Implementation Plan 
(FIP) clock.
---------------------------------------------------------------------------

    \2\ The PM2.5 increments and associated 
implementation rules in question arise from EPA's October 20, 2010, 
final rule for the ``Prevention of Significant Deterioration (PSD) 
for Particulate Matter Less Than 2.5 Micrometers 
(PM2.5)--Increments, Significant Impact Levels (SILs) and 
Significant Monitoring Concentration (SMC)''.
---------------------------------------------------------------------------

    Response: In EPA's May 13, 2014, proposed rulemaking, we stated 
that we were not taking action on Wisconsin's satisfaction of the 
applicable PSD requirements, e.g., incorporating the PM2.5 
increments found in section 110(a)(2)(C), section 110(a)(2)(D)(ii), or 
section 110(a)(2)(J) (see 79 FR 27241 at 27246). Instead, EPA stated 
that it would address Wisconsin's compliance with these requirements in 
a separate rulemaking. In other words, this comment is not germane to 
today's rulemaking.

III. What action is EPA taking?

    For the reasons discussed in our May 13, 2014, proposed rulemaking 
and in the above response to a public comment, EPA is taking final 
action to approve, as proposed, most elements of submissions from 
Illinois, Michigan, Minnesota, and Wisconsin certifying that their 
current SIPs are sufficient to meet the required infrastructure 
elements under sections 110(a)(1) and (2) for the 2008 Pb NAAQS. We are 
also taking final action to disapprove some elements of submissions 
from Illinois and Minnesota related to each state's PSD program. As 
described in the proposed rulemaking, both of these states already 
administer Federally promulgated PSD regulations through delegation, 
and therefore, no practical effect is associated with today's final 
disapproval of those elements (see 79 FR 27241 at 27256-27257).
    To clarify, EPA is taking final action to disapprove the 
infrastructure SIP submissions from Illinois and Minnesota with respect 
to certain PSD requirements including: (i) Provisions that adequate 
address the 2008 Pb NAAQS; (ii) the explicit identification of oxides 
of nitrogen (NOX) as a precursor to ozone consistent with 
the ``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''; (iii) 
the explicit identification of sulfur dioxide (SO2) and 
NOX as PM2.5 precursors (and the significant 
emissions rates for direct PM2.5, and SO2 and 
NOX as its precursors), and the regulation of 
PM2.5 and PM10 \3\ condensables, consistent with 
the requirements of the final rule on the ``Implementation of the New 
Source Review (NSR) Program for Particulate Matter Less than 2.5 
Micrometers (PM2.5)''; (iv) the PM2.5 increments 
and associated implementation rules consistent with the final rule on 
the ``Prevention of Significant Deterioration (PSD) for Particulate 
Matter Less Than 2.5 Micrometers (PM2.5)--Increments, 
Significant Impact Levels (SILs) and Significant Monitoring 
Concentration (SMC)''; and, (v) permitting of greenhouse gas (GHG) 
emitting sources at the Federal Tailoring Rule thresholds.
---------------------------------------------------------------------------

    \3\ PM10 refers to particles with diameters between 
2.5 and 10 microns, oftentimes referred to as ``coarse'' particles.
---------------------------------------------------------------------------

    EPA is also taking final action 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. This

[[Page 41441]]

final disapproval for Illinois and 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 subject to the Federally promulgated PSD regulations, and both 
states administer these regulations via EPA's delegated authority.
    EPA's final actions for each state's satisfaction of infrastructure 
SIP requirements, by element of section 110(a)(2) are contained in the 
table below.

IV. 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.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).

[[Page 41442]]

    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by September 15, 2014. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action for the purposes of 
judicial review nor does it extend the time within which a petition for 
judicial review may be filed, and shall not postpone the effectiveness 
of such rule or action. This action may not be challenged later in 
proceedings to enforce its requirements. (See section 307(b)(2)).
