(Visibility) for the 2012 PM2.5, 2010 NO2, 2010 SO2, and 2008 Ozone 
NAAQS

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to take 
the following four actions regarding the Georgia State Implementation 
Plan (SIP): Approve the portion of Georgia's July 26, 2017, SIP 
submittal seeking to change reliance from the Clean Air Interstate Rule 
(CAIR) to Cross-State Air Pollution Rule (CSAPR) for certain regional 
haze requirements; convert EPA's limited approval/limited disapproval 
of Georgia's regional haze SIP to a full approval; remove EPA's Federal 
Implementation Plan (FIP) for Georgia which replaced reliance on CAIR 
with reliance on CSAPR to address the deficiencies identified in the 
limited disapproval of Georgia's regional haze SIP; and approve the 
visibility prong of Georgia's infrastructure SIP submittals for the 
2012 Fine Particulate Matter (PM2.5), 2010 Nitrogen Dioxide 
(NO2), 2010 Sulfur Dioxide (SO2), and 2008 8-hour 
Ozone National Ambient Air Quality Standards (NAAQS).

SUPPLEMENTARY INFORMATION:

I. Background

A. Regional Haze Plans and Their Relationship With CAIR and CSAPR

    Section 169A(b)(2)(A) of the Clean Air Act (CAA or Act) requires 
states to submit regional haze plans that contain such measures as may 
be necessary to make reasonable progress towards the natural visibility 
goal, including a requirement that certain categories of existing major 
stationary sources built between 1962 and 1977 procure, install, and 
operate Best Available Retrofit Technology (BART) as determined by the 
state. Under the Regional Haze Rule (RHR), states are directed to 
conduct BART determinations for such ``BART-eligible'' sources that may 
be anticipated to cause or contribute to any visibility impairment in a 
Class I area. Rather than requiring source-specific BART controls, 
states also have the flexibility to adopt an emissions trading program 
or other alternative program as long as the alternative provides 
greater reasonable progress towards improving visibility than BART. See 
40 CFR 51.308(e)(2). EPA provided states with this flexibility in the 
RHR, adopted in 1999, and further refined the criteria for assessing 
whether an alternative program provides for greater reasonable progress 
in two subsequent rulemakings. See 64 FR 35714 (July 1, 1999); 70 FR 
39104 (July 6, 2005); 71 FR 60612 (October 13, 2006).
    EPA demonstrated that CAIR would achieve greater reasonable 
progress than BART in revisions to the regional haze program made in 
2005.\1\ See 70 FR 39104 (July 6, 2005). In those revisions, EPA 
amended its regulations to provide that states participating in the 
CAIR cap-and-trade programs pursuant to an EPA-approved CAIR SIP or 
states that remain subject to a CAIR FIP need not require affected 
BART-eligible electric generating units (EGUs) to install, operate, and 
maintain BART for emissions of SO2 and nitrogen oxides 
(NOX). As a result of EPA's determination that CAIR was 
``better-than-BART,'' a number of states in the CAIR region, including 
Georgia, relied on the CAIR cap-and-trade programs as an alternative to 
BART for EGU emissions of SO2 and NOX in 
designing their regional haze plans. These states also relied on CAIR 
as an element of a long-term strategy (LTS) for achieving their 
reasonable progress goals (RPGs) for their regional haze programs. 
However, in 2008, the United States Court of Appeals for the District 
of Columbia Circuit (D.C. Circuit) remanded CAIR to EPA without vacatur 
to preserve the environmental benefits provided by CAIR. North Carolina 
v. EPA, 550 F.3d 1176, 1178 (D.C. Cir. 2008). On August 8, 2011 (76 FR 
48208), acting on the D.C. Circuit's remand, EPA promulgated CSAPR to 
replace CAIR and issued FIPs to implement the rule in CSAPR-subject 
states.\2\ Implementation of CSAPR was scheduled to begin on January 1, 
2012, when CSAPR would have superseded the CAIR program.
---------------------------------------------------------------------------

    \1\ CAIR created regional cap-and-trade programs to reduce 
SO2 and NOX emissions in 27 eastern states 
(and the District of Columbia), including Georgia, that contributed 
to downwind nonattainment or interfered with maintenance of the 1997 
8-hour ozone NAAQS or the 1997 PM2.5 NAAQS.
    \2\ CSAPR requires 28 eastern states to limit their statewide 
emissions of SO2 and/or NOX in order to 
mitigate transported air pollution unlawfully impacting other 
states' ability to attain or maintain four NAAQS: The 1997 ozone 
NAAQS, the 1997 annual PM2.5 NAAQS, the 2006 24-hour 
PM2.5 NAAQS, and the 2008 8-hour ozone NAAQS. The CSAPR 
emissions limitations are defined in terms of maximum statewide 
``budgets'' for emissions of annual SO2, annual 
NOX, and/or ozone-season NOX by each covered 
state's large EGUs. The CSAPR state budgets are implemented in two 
phases of generally increasing stringency, with the Phase 1 budgets 
applying to emissions in 2015 and 2016 and the Phase 2 budgets 
applying to emissions in 2017 and later years.
---------------------------------------------------------------------------

    Due to the D.C. Circuit's 2008 ruling that CAIR was ``fatally 
flawed'' and its resulting status as a temporary measure following that 
ruling, EPA could not fully approve regional haze SIPs to the extent 
that they relied on CAIR to satisfy the BART requirement and the 
requirement for a LTS sufficient to achieve the state-adopted RPGs. On 
these grounds, EPA finalized a limited disapproval of Georgia's 
regional haze

[[Page 4887]]

plan on June 7, 2012 (77 FR 33642), and in the same action, promulgated 
a FIP to replace reliance on CAIR with reliance on CSAPR to address the 
deficiencies in Georgia's regional haze plan. EPA finalized a limited 
approval of Georgia's regional haze SIP on June 28, 2012 (77 FR 38501), 
as meeting the remaining applicable regional haze requirements set 
forth in the CAA and the RHR.
    In the June 7, 2012, limited disapproval action, EPA also amended 
the RHR to provide that participation by a state's EGUs in a CSAPR 
trading program for a given pollutant--either a CSAPR federal trading 
program implemented through a CSAPR FIP or an integrated CSAPR state 
trading program implemented through an approved CSAPR SIP revision--
qualifies as a BART alternative for those EGUs for that pollutant.\3\ 
See 40 CFR 51.308(e)(4). Since EPA promulgated this amendment, numerous 
states covered by CSAPR have come to rely on the provision through 
either SIPs or FIPs.\4\
---------------------------------------------------------------------------

    \3\ Legal challenges to the CSAPR-Better-than-BART rule from 
state, industry, and other petitioners are pending. Utility Air 
Regulatory Group v. EPA, No. 12-1342 (D.C. Cir. filed August 6, 
2012).
    \4\ EPA has promulgated FIPs relying on CSAPR participation for 
BART purposes for Georgia, Indiana, Iowa, Kentucky, Michigan, 
Missouri, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, 
and West Virginia, 77 FR at 33654, and Nebraska, 77 FR 40150, 40151 
(July 6, 2012). EPA has approved SIPs from Alabama, Minnesota, and 
Wisconsin relying on CSAPR participation for BART purposes. See 82 
FR 47393 (October 12, 2017) for Alabama; 77 FR 34801, 34806 (June 
12, 2012) for Minnesota; and 77 FR 46952, 46959 (August 7, 2012) for 
Wisconsin.
---------------------------------------------------------------------------

    Numerous parties filed petitions for review of CSAPR in the D.C. 
Circuit, and on August 21, 2012, the court issued its ruling, vacating 
and remanding CSAPR to EPA and ordering continued implementation of 
CAIR. EME Homer City Generation, L.P. v. EPA, 696 F.3d 7, 38 (D.C. Cir. 
2012). The D.C. Circuit's vacatur of CSAPR was reversed by the United 
States Supreme Court on April 29, 2014, and the case was remanded to 
the D.C. Circuit to resolve remaining issues in accordance with the 
high court's ruling. EPA v. EME Homer City Generation, L.P., 134 S. Ct. 
1584 (2014). On remand, the D.C. Circuit affirmed CSAPR in most 
respects, but invalidated without vacating some of the CSAPR budgets as 
to a number of states. EME Homer City Generation, L.P. v. EPA, 795 F.3d 
118 (D.C. Cir. 2015). The remanded budgets include the Phase 2 
SO2 emissions budgets for Alabama, Georgia, South Carolina, 
and Texas and the Phase 2 ozone-season NOX budgets for 11 
states. This litigation ultimately delayed implementation of CSAPR for 
three years, from January 1, 2012, when CSAPR's cap-and-trade programs 
were originally scheduled to replace the CAIR cap-and-trade programs, 
to January 1, 2015. Thus, the rule's Phase 2 budgets that were 
originally promulgated to begin on January 1, 2014, began on January 1, 
2017.
    On September 29, 2017 (82 FR 45481), EPA issued a final rule 
affirming the continued validity of the Agency's 2012 determination 
that participation in CSAPR meets the RHR's criteria for an alternative 
to the application of source-specific BART. EPA has determined that 
changes to CSAPR's geographic scope resulting from the actions EPA has 
taken or expects to take in response to the D.C. Circuit's budget 
remand do not affect the continued validity of participation in CSAPR 
as a BART alternative, because the changes in geographic scope would 
not have adversely affected the results of the air quality modeling 
analysis upon which the EPA based the 2012 determination. EPA's 
September 29, 2017, determination was based, in part, on EPA's final 
action approving a SIP revision from Alabama (81 FR 59869 (August 31, 
2016)) adopting Phase 2 annual NOX and SO2 
budgets equivalent to the federally-developed budgets and on SIP 
revisions submitted by Georgia and South Carolina to also adopt Phase 2 
annual NOX and SO2 budgets equivalent to the 
federally-developed budgets.\5\ Since that time, EPA has approved the 
SIP revisions from Georgia and South Carolina. See 82 FR 47930 (October 
13, 2017) and 82 FR 47936 (October 13, 2017), respectively.
---------------------------------------------------------------------------

    \5\ EPA proposed to approve the Georgia and South Carolina SIP 
revisions adopting CSAPR budgets on August 16, 2017 (82 FR 38866), 
and August 10, 2017 (82 FR 37389), respectively.
---------------------------------------------------------------------------

    A portion of Georgia's July 26, 2017, SIP submittal seeks to 
correct the deficiencies identified in the June 7, 2012, limited 
disapproval of its regional haze plan submitted on February 11, 2010, 
and supplemented on November 19, 2010, by replacing reliance on CAIR 
with reliance on CSAPR.\6\ Specifically, Georgia requests that EPA 
amend the State's regional haze plan by replacing its reliance on CAIR 
with CSAPR to satisfy SO2 and NOX BART 
requirements and first implementation period SO2 reasonable 
progress requirements for EGUs formerly subject to CAIR,\7\ and to 
support the RPGs for the Class I areas in Georgia for the first 
implementation period. EPA is proposing to approve the regional haze 
portion of the SIP submittal and amend the SIP accordingly.
---------------------------------------------------------------------------

    \6\ On October 13, 2017, (82 FR 47930), EPA approved the 
portions of the July 26, 2017, SIP submission incorporating into 
Georgia's SIP the State's regulations requiring Georgia EGUs to 
participate in CSAPR state trading programs for annual 
NOX and SO2 emissions integrated with the 
CSAPR federal trading programs and thus replacing the corresponding 
FIP requirements. In the October 13, 2017, action, EPA did not take 
any action regarding Georgia's request in this July 26, 2017, SIP 
submission to revise the State's regional haze plan nor regarding 
the prong 4 element of the 2008 8-hour ozone, 2010 1-hour 
NO2, 2010 1-hour SO2, and 2012 
PM2.5 NAAQS.
    \7\ In its regional haze plan, Georgia concluded and EPA found 
acceptable the State's determination that no additional controls 
beyond CAIR are reasonable for SO2 for affected Georgia 
EGUs for the first implementation period, with the exception of five 
EGUs at three facilities owned by Georgia Power. See 77 FR 11464 
(February 27, 2012).
---------------------------------------------------------------------------

B. Infrastructure SIPs

    By statute, plans meeting the requirements of sections 110(a)(1) 
and (2) of the CAA are to be submitted by states within three years (or 
less, if the Administrator so prescribes) after promulgation of a new 
or revised NAAQS to provide for the implementation, maintenance, and 
enforcement of the new or revised NAAQS. EPA has historically referred 
to these SIP submissions made for the purpose of satisfying the 
requirements of sections 110(a)(1) and 110(a)(2) as ``infrastructure 
SIP'' submissions. Sections 110(a)(1) and (2) require states to address 
basic SIP elements such as for monitoring, basic program requirements, 
and legal authority that are designed to assure attainment and 
maintenance of the newly established or revised NAAQS. More 
specifically, section 110(a)(1) provides the procedural and timing 
requirements for infrastructure SIPs. Section 110(a)(2) lists specific 
elements that states must meet for the infrastructure SIP requirements 
related to a newly established or revised NAAQS. The contents of an 
infrastructure SIP submission may vary depending upon the data and 
analytical tools available to the state, as well as the provisions 
already contained in the state's implementation plan at the time in 
which the state develops and submits the submission for a new or 
revised NAAQS.\8\
---------------------------------------------------------------------------

    \8\ For additional information regarding EPA's approach to the 
review of infrastructure SIP submissions, see, e.g., 81 FR 57544 
(August 23, 2016) (proposal to approve portions of Georgia's 
infrastructure SIP for the 2012 PM2.5 NAAQS).
---------------------------------------------------------------------------

    Section 110(a)(2)(D) has two components: 110(a)(2)(D)(i) and 
110(a)(2)(D)(ii). Section 110(a)(2)(D)(i) includes four distinct 
components, commonly referred to as ``prongs,'' that must be addressed 
in infrastructure SIP submissions. The first two prongs, which are 
codified in section

[[Page 4888]]

110(a)(2)(D)(i)(I), are provisions that prohibit any source or other 
type of emissions activity in one state from contributing significantly 
to nonattainment of the NAAQS in another state (prong 1) and from 
interfering with maintenance of the NAAQS in another state (prong 2). 
The third and fourth prongs, which are codified in section 
110(a)(2)(D)(i)(II), are provisions that prohibit emissions activity in 
one state from interfering with measures required to prevent 
significant deterioration of air quality in another state (prong 3) or 
from interfering with measures to protect visibility in another state 
(prong 4). Section 110(a)(2)(D)(ii) requires SIPs to include provisions 
ensuring compliance with sections 115 and 126 of the Act, relating to 
interstate and international pollution abatement.
    Through this action, EPA is proposing to convert the conditional 
approvals of the prong 4 portions of Georgia's infrastructure SIP 
submissions for the 2008 8-hour Ozone, 2010 1-hour NO2, 2010 
1-hour SO2, and 2012 annual PM2.5 NAAQS to full 
approvals, as discussed in section III of this notice.\9\ All other 
applicable infrastructure SIP requirements for these SIP submissions 
have been or will be addressed in separate rulemakings. A brief 
background regarding the NAAQS relevant to this proposal is provided 
below. For comprehensive information on these NAAQS, please refer to 
the Federal Register notices cited in the following subsections.
---------------------------------------------------------------------------

    \9\ On September 26, 2016, EPA conditionally approved the prong 
4 portions of Georgia's infrastructure SIP submissions for the 2008 
8-hour Ozone, 2010 1-hour NO2, 2010 1-hour 
SO2, and 2012 annual PM2.5 NAAQS. See 81 FR 
65899.
---------------------------------------------------------------------------

1. 2010 1-Hour SO2 NAAQS
    On June 2, 2010, EPA revised the 1-hour primary SO2 
NAAQS to an hourly standard of 75 parts per billion (ppb) based on a 3-
year average of the annual 99th percentile of 1-hour daily maximum 
concentrations. See 75 FR 35520 (June 22, 2010). States were required 
to submit infrastructure SIP submissions for the 2010 1-hour 
SO2 NAAQS to EPA no later than June 2, 2013. Georgia 
submitted an infrastructure SIP submission for the 2010 1-hour 
SO2 NAAQS on October 22, 2013, as supplemented on July 25, 
2014. This proposed action only addresses the prong 4 element of that 
submission.\10\
---------------------------------------------------------------------------

    \10\ The other portions of Georgia's 2010 1-hour SO2 
infrastructure submission submitted on October 22, 2013, and 
supplemented on July 25, 2014, were addressed in a separate action. 
See 81 FR 25355 (April 28, 2016).
---------------------------------------------------------------------------

2. 2010 1-Hour NO2 NAAQS
    On January 22, 2010, EPA promulgated a new 1-hour primary NAAQS for 
NO2 at a level of 100 ppb, based on a 3-year average of the 
98th percentile of the yearly distribution of 1-hour daily maximum 
concentrations. See 75 FR 6474 (February 9, 2010). States were required 
to submit infrastructure SIP submissions for the 2010 1-hour 
NO2 NAAQS to EPA no later than January 22, 2013. Georgia 
submitted an infrastructure SIP submission for the 2010 1-hour 
NO2 NAAQS on March 25, 2013. This proposed action only 
addresses the prong 4 element of this submission.\11\
---------------------------------------------------------------------------

    \11\ The other portions of Georgia's March 25, 2013, 2010 1-hour 
NO2 infrastructure submission were addressed in a 
separate action. See 81 FR 63106 (September 14, 2016).
---------------------------------------------------------------------------

3. 2012 PM2.5 NAAQS
    On December 14, 2012, EPA revised the annual primary 
PM2.5 NAAQS to 12 micrograms per cubic meter ([mu]g/m\3\). 
See 78 FR 3086 (January 15, 2013). States were required to submit 
infrastructure SIP submissions for the 2012 PM2.5 NAAQS to 
EPA no later than December 14, 2015. Georgia submitted an 
infrastructure SIP submission for the 2012 PM2.5 NAAQS on 
December 14, 2015. This proposed action only addresses the prong 4 
element of that submission.\12\
---------------------------------------------------------------------------

    \12\ Most of the other portions of Georgia's December 14, 2015, 
PM2.5 infrastructure submission were addressed in a 
separate action. See 81 FR 83156 (November 21, 2016). EPA is 
evaluating the remaining portions of Georgia's December 14, 2015, 
PM2.5 infrastructure submission and will consider action 
on those portions in a separate action.
---------------------------------------------------------------------------

4. 2008 8-Hour Ozone NAAQS
    On March 12, 2008, EPA revised the 8-hour Ozone NAAQS to 0.075 
parts per million. See 73 FR 16436 (March 27, 2008). States were 
required to submit infrastructure SIP submissions for the 2008 8-hour 
Ozone NAAQS to EPA no later than March 12, 2011. Georgia submitted an 
infrastructure SIP for the 2008 8-hour Ozone NAAQS on May 14, 2012. 
This proposed action only addresses the prong 4 element of that 
submission.\13\
---------------------------------------------------------------------------

    \13\ The other portions of Georgia's May 14, 2012, 2008 ozone 
infrastructure SIP submission were addressed in a separate action. 
See 80 FR 61109 (October 9, 2015).
---------------------------------------------------------------------------

II. What are the prong 4 requirements?

    CAA section 110(a)(2)(D)(i)(II) requires a state's implementation 
plan to contain provisions prohibiting sources in that state from 
emitting pollutants in amounts that interfere with any other state's 
efforts to protect visibility under part C of the CAA (which includes 
sections 169A and 169B). EPA most recently issued guidance for 
infrastructure SIPs on September 13, 2013 (2013 Guidance).\14\ The 2013 
Guidance states that these prong 4 requirements can be satisfied by 
approved SIP provisions that EPA has found to adequately address any 
contribution of that state's sources that impacts the visibility 
program requirements in other states. The 2013 Guidance also states 
that EPA interprets this prong to be pollutant-specific, such that the 
infrastructure SIP submission need only address the potential for 
interference with protection of visibility caused by the pollutant 
(including precursors) to which the new or revised NAAQS applies.
---------------------------------------------------------------------------

    \14\ ``Guidance on Infrastructure State Implementation Plan 
(SIP) Elements under Clean Air Act Sections 110(a)(1) and 
110(a)(2),'' Memorandum from Stephen D. Page, September 13, 2013.
---------------------------------------------------------------------------

    The 2013 Guidance lays out how a state's infrastructure SIP 
submission may satisfy prong 4. One way that a state can meet the 
requirements is via confirmation in its infrastructure SIP submission 
that the state has an approved regional haze plan that fully meets the 
requirements of 40 CFR 51.308 or 51.309. 40 CFR 51.308 and 51.309 
specifically require that a state participating in a regional planning 
process include all measures needed to achieve its apportionment of 
emission reduction obligations agreed upon through that process. A 
fully approved regional haze plan will ensure that emissions from 
sources under an air agency's jurisdiction are not interfering with 
measures required to be included in other air agencies' plans to 
protect visibility.
    Alternatively, in the absence of a fully approved regional haze 
plan, a state may meet the requirements of prong 4 through a 
demonstration in its infrastructure SIP submission that emissions 
within its jurisdiction do not interfere with other air agencies' plans 
to protect visibility. Such an infrastructure SIP submission would need 
to include measures to limit visibility-impairing pollutants and ensure 
that the reductions conform with any mutually agreed regional haze RPGs 
for mandatory Class I areas in other states.

III. What is EPA's analysis of how Georgia addressed prong 4 and 
regional haze?

    Georgia's May 14, 2012, 2008 8-hour Ozone infrastructure SIP 
submission; March 25, 2013, 2010 1-hour NO2 submission; 
October 22, 2013, 2010 1-hour SO2 submission as supplemented

[[Page 4889]]

on July 25, 2014; and December 14, 2015, 2012 annual PM2.5 
submission rely on the State having a fully approved regional haze plan 
to satisfy its prong 4 requirements. However, EPA has not fully 
approved Georgia's regional haze plan, as the Agency issued a limited 
disapproval of the State's original regional haze plan on June 7, 2012, 
due to its reliance on CAIR.
    On May 26, 2016, Georgia submitted a commitment letter to EPA to 
submit a SIP revision that adopts provisions for participation in the 
CSAPR annual NOX and annual SO2 trading programs, 
including annual NOX and annual SO2 budgets that 
are at least as stringent as the budgets codified for Georgia, and 
revises its regional haze plan to replace reliance on CAIR with CSAPR 
for certain regional haze provisions. In its letter, Georgia committed 
to providing this SIP revision within one year of EPA's final 
conditional approval of the prong 4 portions of the infrastructure SIP 
revisions. On September 26, 2016 (81 FR 65899), EPA conditionally 
approved the prong 4 portion of Georgia's infrastructure SIP 
submissions for the 2008 8-hour Ozone, 2010 1-hour NO2, 2010 
1-hour SO2, and 2012 annual PM2.5 NAAQS based on 
this commitment letter from the State. In accordance with the State's 
May 26, 2016, commitment letter, Georgia submitted a SIP revision on 
July 26, 2017, to adopt provisions for participation in the CSAPR 
annual NOX and annual SO2 trading programs and to 
replace reliance on CAIR with reliance on CSAPR for certain regional 
haze provisions. As noted above, EPA approved the portion of Georgia's 
July 26, 2017, SIP revision adopting CSAPR. See 82 FR 47930 (October 
13, 2017).
    EPA is proposing to approve the regional haze portion of the 
State's July 26, 2017, SIP revision replacing reliance on CAIR with 
CSAPR, and to convert EPA's previous action on Georgia's regional haze 
plan from a limited approval/limited disapproval to a full approval 
because final approval of this portion of the SIP revision would 
correct the deficiencies that led to EPA's limited approval/limited 
disapproval of the State's regional haze plan. Specifically, EPA's 
approval of the regional haze portion of Georgia's July 26, 2017, SIP 
revision would satisfy the SO2 and NOX BART 
requirements and first implementation period SO2 reasonable 
progress requirements for EGUs formerly subject to CAIR and the 
requirement that a LTS include measures as necessary to achieve the 
State-adopted RPGs. Thus, EPA is also proposing to remove EPA's FIP for 
Georgia which replaced reliance on CAIR with reliance on CSAPR to 
address the deficiencies identified in the limited disapproval of 
Georgia's regional haze SIP. Because a state may satisfy prong 4 
requirements through a fully approved regional haze plan, EPA is 
therefore also proposing to convert the conditional approvals to full 
approvals of the prong 4 portion of Georgia's May 14, 2012, 2008 8-hour 
Ozone infrastructure SIP submission; March 25, 2013, 2010 1-hour 
NO2 submission; October 22, 2013, 2010 1-hour SO2 
submission as supplemented on July 25, 2014; and December 14, 2015, 
2012, annual PM2.5 submissions.

IV. Proposed Action

    As described above, EPA is proposing to take the following actions: 
(1) Approve the regional haze portion of Georgia's July 26, 2017, SIP 
submission to change reliance from CAIR to CSAPR; (2) convert EPA's 
limited approval/limited disapproval of Georgia's February 11, 2010, 
regional haze plan as supplemented on November 19, 2010, to a full 
approval; (3) remove EPA's FIP for Georgia which replaced reliance on 
CAIR with reliance on CSAPR to address the deficiencies identified in 
the limited disapproval of Georgia's regional haze SIP; and (4) convert 
EPA's September 26, 2016, conditional approvals to full approvals of 
the prong 4 portion of Georgia's May 14, 2012, 2008 8-hour Ozone 
submission; March 25, 2013, 2010 1-hour NO2 submission; the 
State's October 22, 2013, 2010 1-hour SO2 submission as 
supplemented on July 25, 2014; and the State's December 14, 2015, 2012 
annual PM2.5 submission. All other applicable infrastructure 
requirements for the infrastructure SIP submissions have been or will 
be addressed in separate rulemakings.

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
federal regulations. See 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, these 
proposed actions merely propose to approve state law as meeting Federal 
requirements and do not impose additional requirements beyond those 
imposed by state law. For that reason, these proposed actions:
     Are not significant regulatory actions subject to review 
by the Office of Management and Budget under Executive Orders 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     Are not Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory actions because SIP approvals are exempted under 
Executive Order 12866;
     Do not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Are 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.);
     Do 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);
     Do not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Are not economically significant regulatory actions based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Are not significant regulatory actions subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Are 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
     Do 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).
    The SIP is not approved to apply on any Indian reservation land or 
in any other area where EPA or an Indian tribe has demonstrated that a 
tribe has jurisdiction. In those areas of Indian country, the rule does 
not have tribal implications as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000), nor will it impose substantial direct 
costs on tribal governments or preempt tribal law.
