The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the State of Delaware. The Clean Air Act's (CAA) Good Neighbor Provision requires EPA and states to address the interstate transport of air pollution that affects the ability of downwind states to attain and maintain the national ambient air quality standards (NAAQS). Specifically, the Good Neighbor Provision requires each state in its SIP to prohibit emissions that will significantly contribute to nonattainment, or interfere with maintenance, of a NAAQS in a downwind state. Delaware submitted a SIP revision on March 23, 2013 that addresses the interstate transport requirements for the 2008 ozone NAAQS. On September 27, 2017, EPA published a proposed rule and a direct final rule approving Delaware's SIP in regard to the Good Neighbor Provision. However, EPA received adverse comments on its September 27, 2017 proposed rule, and subsequently withdrew the accompanying direct final rule. After considering the comments, EPA is approving Delaware's SIP revision submittal in regard to the Good Neighbor Provision for the 2008 ozone NAAQS in accordance with the requirements of the CAA.

Air Plan Approval; Delaware; State Implementation Plan for 
Interstate Transport for the 2008 Ozone Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving a state 
implementation plan (SIP) revision submitted by the State of Delaware. 
The Clean Air Act's (CAA) Good Neighbor Provision requires EPA and 
states to address the interstate transport of air pollution that 
affects the ability of downwind states to attain and maintain the 
national ambient air quality standards (NAAQS). Specifically, the Good 
Neighbor Provision requires each state in its SIP to prohibit emissions 
that will significantly contribute to nonattainment, or interfere with 
maintenance, of a NAAQS in a downwind state. Delaware submitted a SIP 
revision on March 23, 2013 that addresses the interstate transport 
requirements for the 2008 ozone NAAQS. On September 27, 2017, EPA 
published a proposed rule and a direct final rule approving Delaware's 
SIP in regard to the Good Neighbor Provision. However, EPA received 
adverse comments on its September 27, 2017 proposed rule, and 
subsequently withdrew the accompanying direct final rule. After 
considering the comments, EPA is approving Delaware's SIP revision 
submittal in regard to the Good Neighbor Provision for the 2008 ozone 
NAAQS in accordance with the requirements of the CAA.

DATES: This final rule is effective on April 23, 2018.

SUPPLEMENTARY INFORMATION: On March 27, 2013, the State of Delaware 
through the Delaware Department of Natural Resources and Environmental 
Control (DNREC) submitted a revision to its SIP to satisfy the 
requirements of section 110(a)(2), including 110(a)(2)(D)(i)(I), of the 
CAA as it relates to the 2008 ozone NAAQS. On September 27, 2017, EPA 
published a notice of proposed rulemaking (NPR) (82 FR 44984) and an 
accompanying direct final rule (DFR) (82 FR 44932) for the State of 
Delaware, approving the portion of the March 27, 2013 Delaware SIP 
revision addressing prongs 1 and 2 of the interstate transport 
requirements for section 110(a)(2)(D)(i)(I) for the 2008 ozone NAAQS. 
EPA received comments on the proposed rulemaking and the Agency 
subsequently withdrew the DFR on November 20, 2017 (82 FR 55052). This 
action responds to the comments received and finalizes EPA's approval 
of the portion of the March 27, 2013 Delaware SIP revision addressing 
section 110(a)(2)(D)(i)(I) of the CAA for the 2008 ozone NAAQS.

I. Background

    On March 12, 2008, EPA revised the levels of the primary and 
secondary ozone standards from 0.08 parts per million (ppm) to 0.075 
ppm (73 FR 16436). The CAA requires states to submit, within three 
years after promulgation of a new or revised NAAQS, SIP revisions 
meeting the applicable elements of sections 110(a)(1) and (2).\1\ 
Several of these applicable elements are delineated within section 
110(a)(2)(D)(i) of the CAA. Section 110(a)(2)(D)(i) generally requires 
SIPs to contain adequate provisions to prohibit in-state emissions 
activities from having certain adverse air quality effects on 
neighboring states due to interstate transport of air pollution. There 
are four prongs within section 110(a)(2)(D)(i) of the CAA; section 
110(a)(2)(D)(i)(I) contains prongs 1 and 2, while section 
110(a)(2)(D)(i)(II) includes prongs 3 and 4. This action addresses the 
first two prongs, which are also collectively known as the Good 
Neighbor Provision. Pursuant to prongs 1 and 2, a state's SIP must 
contain adequate provisions to prohibit any source or other type of 
emissions activity within the state from emitting air pollutants that 
will ``contribute significantly to nonattainment in, or interfere with 
maintenance by, any other state with respect to any such national 
primary or secondary ambient air quality standard.'' Under section 
110(a)(2)(D)(i)(I) of the CAA, EPA gives independent significance to 
the matter of nonattainment (prong 1) and to that of maintenance (prong 
2).
---------------------------------------------------------------------------

    \1\ SIP revisions that are intended to meet the requirements of 
section 110(a) of the CAA are often referred to as infrastructure 
SIPs and the elements under 110(a) are referred to as infrastructure 
requirements.
---------------------------------------------------------------------------

    On March 27, 2013, the State of Delaware through DNREC submitted a 
SIP revision intended to address the requirements of section 110(a)(2) 
of the CAA for the 2008 ozone NAAQS. In this rulemaking action, EPA is 
approving one portion of Delaware's March 27, 2013 submittal--the 
portion addressing prongs 1 and 2 of section 110(a)(2)(D)(i)(I) of the 
CAA. EPA previously acted on other portions of Delaware's March 27, 
2013 SIP submittal for the 2008 ozone NAAQS.\2\
---------------------------------------------------------------------------

    \2\ On April 3, 2014 (79 FR 18644), EPA approved portions of 
Delaware's March 27, 2013 submittal for the 2008 ozone NAAQS 
addressing the following: CAA section 110(a)(2)(A), (B), (C), 
(D)(i)(II), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M). In 
that action, EPA stated it would take later action on the portion of 
the March 27, 2013 SIP submittal addressing section 
110(a)(2)(D)(i)(I) of the CAA.
---------------------------------------------------------------------------

    To demonstrate that its SIP adequately addresses interstate 
transport for the 2008 ozone NAAQS, Delaware's March 27, 2013 submittal 
identifies measures in its approved SIP that cover stationary, mobile, 
and area sources of volatile organic compounds (VOCs) and nitrogen 
oxides (NOX), both of which are precursors to ozone. 
Delaware's submittal identifies SIP-approved regulations that reduce 
VOC and NOX emissions from a variety of stationary sources 
within the State, including power plants, industrial boilers, and 
peaking units. Delaware states in its submittal that its sources are 
generally controlled with best available control technology (BACT) or 
lowest achievable emission rate (LAER) level controls. Delaware notes 
that sources are generally controlled on a unit-by-unit basis at costs 
ranging from $1,300 to $11,000 per ton of NOX reduced.\3\ To

[[Page 12670]]

substantiate its control costs and feasibility claims, Delaware 
includes an assessment of potential additional control measures on 
mobile and stationary sources, including both electric generating unit 
(EGU) and non-EGU categories. The assessment evaluates, for each source 
or category, the technical and economic feasibility for additional 
NOX and VOC reductions. For non-EGUs, Delaware could not 
identify any cost-effective controls beyond those already required by 
the SIP; estimating that at about $5,000 per ton of pollutant (VOC, 
NOX) reduced, only a small amount of additional emission 
reductions would be seen.\4\ In its submittal, Delaware identifies the 
following Delaware regulations, which are already included in its 
approved SIP: 7 DE Admin. Code 1125 (New Source Review); 7 DE Admin. 
Code 1112 (NOX Reasonably Available Control Technology 
(RACT)); 7 DE Admin. Code 1124 (VOC RACT); 7 DE Admin. Codes 1126 and 
1136 (vehicle inspection and maintenance (I/M) control measures). In 
its submittal, Delaware concludes that it has satisfied the 
requirements for section 110(a)(2)(D)(i)(I) of the CAA for the 2008 
ozone NAAQS because its sources are already well controlled for 
NOX and VOCs, and because further reductions beyond the 
State's current SIP measures for NOX and VOCs are not 
economically feasible.

110(a)(2) Infrastructure Requirements for the 2008 Ozone NAAQS, 
www.regulations.gov, Docket number EPA-R03-OAR-2013-0408.
    \4\ In its March 27, 2013 submittal, Delaware stated that at 
about $5,000 per ton, the State could reduce NOX 
emissions by about 375 tons per year (tpy) and VOCs by 255 tpy.
---------------------------------------------------------------------------

II. EPA Analysis

A. Cross-State Air Pollution Rule Update

    The CAA gives EPA a backstop role, as appropriate, in the event 
that states fail to submit approvable SIPs. On September 8, 2016, EPA 
took steps to effectuate this backstop role with respect to emissions 
in 22 eastern states (not including Delaware) by finalizing an update 
to the Cross-State Air Pollution Rule (CSAPR) ozone season program that 
addresses the obligations of the Good Neighbor Provision for the 2008 
ozone NAAQS. 81 FR 74504. The CSAPR Update established a federal 
trading program for affected EGUs to reduce the interstate transport of 
ozone pollution in the May-September ozone season in the eastern United 
States, and thereby help downwind states and communities meet and 
maintain the 2008 ozone NAAQS.\5\ The CSAPR Update uses the same 
framework EPA used when developing the original CSAPR, EPA's transport 
rule addressing the 1997 ozone NAAQS as well as the 1997 and 2006 fine 
particulate matter (PM2.5) NAAQS. This framework establishes 
the following four-step process to address the requirements of the Good 
Neighbor Provision:
---------------------------------------------------------------------------

    \5\ Ground-level ozone is formed when VOCs and NOX 
combine in the presence of sunlight. The rate of ozone production 
can be limited by the availability of either VOCs or NOX. 
In the case of the eastern states, ozone reduction has shown to be 
more effective by reducing NOX which is why reducing 
NOX emissions is the focus of both the CSAPR Update and 
this rulemaking action regarding Delaware.
---------------------------------------------------------------------------

    (1) identify downwind receptors that are expected to have problems 
attaining or maintaining the NAAQS;
    (2) determine which upwind states contribute to these identified 
problems in amounts sufficient to link them to the downwind air quality 
problems;
    (3) identify and quantify, for states linked to downwind air 
quality problems, upwind emissions that significantly contribute to 
nonattainment or interfere with maintenance of a NAAQS; and
    (4) reduce the identified upwind emissions for states that are 
found to have emissions that significantly contribute to nonattainment 
or interfere with maintenance of the NAAQS downwind by adopting 
permanent and enforceable measures through a SIP or by participating in 
a federal trading program.
    This four-step framework is informed by cost-effectiveness and 
feasibility of controls, emissions, meteorology, and air quality 
factors. Notably, the determination as to whether a linked state 
significantly contributes to nonattainment or interferes with 
maintenance of the NAAQS in a downwind state is made at step 3 based on 
a multi-factor evaluation of control costs, available NOX 
emission reductions, and air quality improvements (including 
consideration of potential over-control).\6\
---------------------------------------------------------------------------

    \6\ CSAPR Update final rule. 81 FR 74504, 74519 (October 26, 
2016).
---------------------------------------------------------------------------

B. EPA's Assessment of Delaware in the CSAPR Update

    While EPA's CSAPR Update analysis included an assessment of 
Delaware, the State was not included in the final CSAPR Update federal 
trading program for EGUs. Nonetheless, the CSAPR Update includes 
technical information and related analysis that can assist EPA and 
states with evaluating the requirements of section 110(a)(2)(D)(i)(I) 
of the CAA for the 2008 ozone NAAQS. In the CSAPR Update, EPA found in 
steps 1 and 2 of the four-step framework that Delaware is linked to a 
downwind maintenance receptor in Philadelphia County, Pennsylvania. 81 
FR 74538. Accordingly, EPA further evaluated Delaware in step 3 of the 
framework to determine whether there were cost-effective NOX 
emission reductions available from EGUs in the state.
    In the CSAPR Update, EPA examined emission reductions available at 
various levels of control stringency, represented by cost-thresholds of 
$0 per ton; $800 per ton; $1,400 per ton; $3,400 per ton; $5,000 per 
ton; and $6,400 per ton. This analysis accounted for existing limits on 
Delaware EGUs in the State's March 27, 2013 SIP submittal. Notably, for 
Delaware, EPA's assessment of EGUs' NOX reduction potential 
showed no cost-effective reductions available in Delaware within the 
allotted short term implementation timeframe (by 2017 for the 2008 
ozone NAAQS) at every cost threshold EPA evaluated because the Delaware 
EGUs are already equivalently controlled. 81 FR at 74553. In addition, 
Delaware's March 27, 2013 submittal evaluated sources other than EGUs 
and the State could not identify any cost-efficient controls for 
reducing VOCs or NOX beyond those already required by the 
SIP.

C. Air Quality Assessment Tool

    The emission reductions at the various levels of control stringency 
analyzed by EPA could result in air quality improvements such that 
individual receptors drop below the level of the 2008 ozone NAAQS based 
on the cumulative air quality improvement from the states analyzed. 
Therefore, in finalizing the CSAPR Update, EPA explicitly evaluated 
whether the potential emission budgets evaluated for each state would 
result in over-control of upwind state emissions,\7\ as required by 
precedents of the Supreme Court and D.C. Circuit.\8\ Specifically, EPA 
evaluated whether at each level of NOX emission budget, the 
identified downwind ozone problems (i.e., nonattainment or maintenance 
problems) are resolved.
---------------------------------------------------------------------------

    \7\ In this rulemaking action, the term ``over-control'' 
describes the possibility that a state might be compelled to reduce 
emissions beyond the point at which every affected downwind state is 
projected to attain and maintain the NAAQS. See EPA v. EME Homer 
City Generation, L.P., 134 S. Ct. 2014; EME Homer City Generation, 
L.P. v. EPA, 795 F.3d 118, 127 (D.C. Cir. July 28, 2015).
    \8\ Id.
---------------------------------------------------------------------------

    In examining emissions contribution to nonattainment and 
maintenance receptors for the 2008 ozone NAAQS, EPA used the Air 
Quality Assessment

[[Page 12671]]

Tool (AQAT) to estimate the air quality impacts of the upwind state EGU 
NOX emission budgets on downwind ozone pollution levels for 
each of the assessed EGU NOX emission budget levels. EPA 
assessed the magnitude of air quality improvement at each receptor at 
each level of control, examined whether receptors are considered to be 
resolved,\9\ and looked at the individual contributions of emissions 
from each state to each of that state's linked receptors. EPA also 
examined each state's air quality contributions at each potential level 
of control stringency, assessing whether a state maintained at least 
one linkage to a receptor that was estimated to continue to have 
nonattainment or maintenance problems with the 2008 ozone NAAQS.
---------------------------------------------------------------------------

    \9\ When the average and maximum design values of a receptor 
decrease to values below 76 parts per billion (ppb) or (0.076 ppm), 
the nonattainment and maintenance issues of the receptor would be 
considered resolved.
---------------------------------------------------------------------------

    As stated in section VI.D. in the preamble of the final CSAPR 
Update and in the Ozone Transport Policy Analysis Technical Support 
Document (TSD) used to support the final CSAPR Update, EPA's AQAT 
assessment indicates that an emissions budget reflecting $800 per ton 
of NOX reduced would resolve the maintenance problem at the 
Philadelphia, Pennsylvania maintenance receptor (monitor ID 4210100124) 
to which Delaware was linked. Thus, EPA estimated that implementation 
of the CSAPR Update, along with NOX controls in Delaware's 
SIP submittal, are anticipated to resolve the lone downwind receptor to 
which Delaware is linked.

D. Conclusion

    In conclusion, when evaluating all the available information, EPA 
finds that Delaware has implemented measures that have reduced 
statewide VOC and NOX emissions and that should continue to 
reduce emissions within the State. The maintenance receptor that 
Delaware is linked to in the CSAPR Update is projected by EPA to have 
its maintenance issue resolved with CSAPR Update implementation \10\ 
and existing NOX controls in place in Delaware. EPA further 
finds Delaware has no cost-effective EGU NOX emissions 
reduction potential by 2017, beyond what is already required in 
Delaware's SIP, at or below the maximum $6,400 per ton cost-threshold 
evaluated in the CSAPR Update. Additionally, EPA finds that Delaware's 
non-EGU sources are also well-controlled and that there is limited VOC 
and NOX emissions reduction potential, beyond what it 
already required in the State's SIP, at and below a $5,000 per ton 
cost-threshold. Thus, EPA finds Delaware has fully satisfied its 
obligation with respect to the requirements of section 
110(a)(2)(D)(i)(I) of the CAA for the 2008 ozone NAAQS, and EPA is 
approving the portion of the March 27, 2013 Delaware SIP submittal 
addressing prongs 1 and 2 of the interstate transport requirements for 
the 2008 ozone NAAQS.
---------------------------------------------------------------------------

    \10\ EPA notes that the preliminary 2014-2016 design value for 
the identified CSAPR Update Philadelphia maintenance site does not 
reflect the air quality improvements anticipated as a result of the 
CSAPR Update implementation because sources began compliance with 
the rule in May 1, 2017.
---------------------------------------------------------------------------

III. Summary of Public Comments and EPA Responses

    During the comment period, EPA received several anonymous comments 
on the rulemaking. EPA provides responses to two of these comments, 
below. All other comments received were not specific to this action and 
thus are not addressed here.
    Comment #1: The first commenter stated that EPA cannot rely on 
federal implementation plans (FIPs) to reduce the downwind contribution 
of air pollution to another state and pointed out that section 
110(a)(2)(D) of the CAA requires that measures addressing interstate 
transport must be approved into the State's SIP. The commenter believes 
that EPA stated in its DFRN \11\ that Delaware has been shown to 
significantly contribute to the Philadelphia receptor, and subsequently 
the commenter states that EPA cannot approve Delaware's plan because 
the necessary measures to reduce interstate transport of air pollutants 
to other states cannot be met without a FIP. Further, the commenter 
states that ``the fact that Delaware is included in the Federal plan 
means that EPA has already determined that the state's own plan does 
not meet the requirement of 110.'' The commenter asks EPA to reconsider 
and disapprove Delaware's plan until ``such time as Delaware is able to 
implement its own plan and that plan is approved into the SIP.''
---------------------------------------------------------------------------

    \11\ September 27, 2017 (82 FR 44932).
---------------------------------------------------------------------------

    Response: As an initial matter, EPA disagrees that FIPs are an 
inappropriate tool to address the requirements of section 
110(a)(2)(D)(i)(I). Pursuant to section 110(c), whenever EPA finds that 
a state has failed to make a required submission or disapproves a 
state's submission, the Agency has an obligation to promulgate a FIP to 
address the deficiencies in a state's plan, including the requirements 
of section 110(a)(2)(D)(i)(I). Since 2005, EPA has relied on federal 
trading programs, such as the Clean Air Interstate Rule (CAIR), its 
replacement CSAPR, and the CSAPR Update in order to reduce the downwind 
contributions of air pollution to another state via the promulgation of 
FIPs. In 2014, the United States Supreme Court upheld CSAPR in EPA v. 
EME Homer City Generation, L.P., finding that EPA had the authority to 
promulgate a FIP upon a determination that a state had failed to make 
an adequate submission. 134 S. Ct. 1584, 1601 (2014). Thus, EPA 
disagrees with the commenter's premise that EPA cannot rely on federal 
plans to reduce the downwind contribution of air pollution to another 
state in addressing section 110(a)(2)(D) of the CAA.
    Nonetheless, whether or not EPA may rely on a FIP to address the 
requirements of the Good Neighbor Provision is irrelevant to EPA's 
action on Delaware's SIP because its approval is not contingent on a 
FIP. EPA did not promulgate a FIP for Delaware in the CSAPR Update (the 
federal plan to which the commenter presumably refers). Accordingly, 
contrary to the commenter's assertion, EPA did not already determine in 
that rulemaking that the State's submittal does not meet the 
requirements of section 110(a)(2)(D)(i)(I) of the CAA. Rather, EPA 
explicitly stated that it would further evaluate the state's compliance 
with the Good Neighbor Provision when it evaluated the State's SIP in a 
separate action. See 81 FR at 74553.
    EPA also disagrees with the commenter's assertion that EPA stated 
in its September 27, 2017 DFR that Delaware was shown to 
``significantly contribute'' to the Philadelphia, Pennsylvania 
receptor. In fact, as EPA stated in its DFR and again in this final 
notice, the Agency used a four-step framework to evaluate each state in 
order to determine whether the state will significantly contribute to 
nonattainment or interfere with maintenance of downwind air quality. 
While EPA's analysis did determine that the Philadelphia monitor/
receptor was expected to have problems attaining or maintaining the 
2008 ozone NAAQS (step 1 of four-step framework) and that Delaware was 
linked to the downwind air of the Philadelphia receptor (step 2 of the 
framework), this is not equivalent to a determination that Delaware 
will significantly contribute to nonattainment or interfere with 
maintenance. Rather, this determination is made at step 3 of the 
framework and depends on whether EGUs in the linked state have 
available cost-effective NOX

[[Page 12672]]

emission reductions.\12\ As noted above, EPA determined that Delaware's 
sources were already being controlled at levels equivalent to the cost-
threshold applied to linked states in the CSAPR Update, and therefore 
had no cost-effective emission reductions available from EGUs in the 
State. Thus, EPA did not conclude that Delaware significantly 
contributes to nonattainment or interferes with maintenance in the 
CSAPR Update and did not involve the State in a FIP.
---------------------------------------------------------------------------

    \12\ The Supreme Court held that it was a permissible 
interpretation of the statute to apportion responsibility for states 
linked to nonattainment receptors considering ``both the magnitude 
of upwind States' contributions and the cost associated with 
eliminating them.'' EPA v. EME Homer City Generation, L.P., 134 S. 
Ct. at 1606.
---------------------------------------------------------------------------

    Therefore, EPA disagrees with the commenter that Delaware relies on 
any FIP to meet section 110(a)(2)(D) of the CAA for the 2008 ozone 
NAAQS, and the Agency thus disagrees that it should disapprove 
Delaware's plan until ``such time as Delaware is able to implement its 
own plan and that plan is approved into the SIP.'' EPA has discussed in 
section II of this notice why EPA agrees with Delaware's determination 
in its March 27, 2013 SIP revision submittal that the SIP contains the 
necessary measures to address prongs 1 and 2 of the interstate 
transport requirements for section 110(a)(2)(D)(i)(I) for the 2008 
ozone NAAQS.
    Comment: The second commenter stated that EPA did not address a 
March 28, 2017 Executive Order regarding the promotion of energy 
independence and economic growth. The Executive Order required federal 
agencies to review all regulations to ensure they do not impose 
unnecessary burdens on the economy.
    Response: The March 28, 2017 Executive Order (E.O.) \13\ pertains 
to reviewing existing regulations, orders, guidance documents, 
policies, and any other similar agency actions (collectively, agency 
action) that potentially burden the development or use of domestically 
produced energy resources, with attention to oil, natural gas, coal, 
and nuclear energy. EPA does not believe that EPA's regulatory action 
to approve Delaware's SIP submittal is inconsistent with this E.O. 
Specifically, EPA is approving Delaware's submission on the grounds 
that the controls that it already imposes address interstate transport 
of emissions, such that its sources do not significantly contribute to 
nonattainment or interfere with maintenance in another state. In any 
event, if a SIP submittal from a state meets all the requirements of 
section 110(a)(2) of the CAA, including the required emission 
limitations, then section 110(k)(3) of the CAA requires that EPA shall 
approve the SIP submission. As explained in section II of this action, 
the Agency finds that the Delaware SIP meets the requirements of 
section 110(a)(2)(D)(i)(I) of the CAA with respect to the 2008 ozone 
NAAQS. Thus, under the plain language of section 110(k)(3), EPA must 
approve the SIP submission, and cannot disapprove it based on the March 
28, 2017 E.O.
---------------------------------------------------------------------------

    \13\ Based on the comment, EPA assumes the E.O. in question is 
E.O. 13738, Promoting Energy Independence and Economic Growth, 
signed March 28, 2017.
---------------------------------------------------------------------------

IV. Final Action

    EPA is approving the portion of the March 27, 2013 Delaware SIP 
revision addressing prongs 1 and 2 of the interstate transport 
requirements for section 110(a)(2)(D)(i)(I) of the CAA for the 2008 
ozone NAAQS for the reasons discussed in this rulemaking.
    On April 3, 2014 (79 FR 18644), EPA finalized approval of the 
following infrastructure elements or portions thereof from the March 
27, 2013 submittal: CAA section 110(a)(2)(A), (B), (C), (D)(i)(II), 
(D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M). This action 
approves the remaining portions of the March 27, 2013 SIP revision, 
which address prongs 1 and 2 of section 110(a)(2)(D)(i)(I) of the CAA, 
also known as the Good Neighbor Provision. EPA did not take action upon 
these elements in the Agency's prior SIP approval action, published on 
April 3, 2014 (79 FR 18644).

V. Statutory and Executive Order Reviews

A. General Requirements

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866.
     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.

B. Submission to Congress and the Comptroller General

    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.

[[Page 12673]]

This action is not a ``major rule'' as defined by 5 U.S.C. 804(2).

C. Petitions for Judicial Review

    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by May 22, 2018. 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, addressing Delaware's interstate transport for the 
2008 ozone NAAQS, may not be challenged later in proceedings to enforce 
its requirements. (See section 307(b)(2).)
