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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking direct 
final action to approve a portion of 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 has submitted a SIP revision that 
addresses the interstate transport requirements, among other things, 
for the 2008 ozone NAAQS. EPA has determined that Delaware's SIP has 
adequate provisions to prohibit the state from significantly 
contributing to nonattainment, or interfering with maintenance, of the 
2008 ozone NAAQS in any other state. EPA is approving Delaware's SIP 
revision submittal in regards to the good neighbor interstate transport 
provision in accordance with the requirements of the CAA.

DATES: This rule is effective on December 26, 2017 without further 
notice, unless EPA receives adverse written comment by October 27, 
2017. If EPA receives such comments, it will publish a timely 
withdrawal of the direct final rule in the Federal Register and inform 
the public that the rule will not take effect.

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), of the 
CAA as it relates to 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 direct final action 
addresses the first two prongs, which are also collectively known as 
the good neighbor provision. According to the CAA's good neighbor 
provision located within section 110(a)(2)(D)(i)(I), 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 
``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.
---------------------------------------------------------------------------

II. Summary of SIP Revision

    On March 27, 2013, the State of Delaware through DNREC provided a 
SIP revision submittal to satisfy 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.

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

[[Page 44933]]

    In order 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 (NO<INF>X</INF>), both of which are 
precursors to ozone. Delaware's submittal identifies SIP-approved 
regulations that reduce VOCs and NO<INF>X</INF> 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 a cost of $1,300 to $11,000 per ton of 
NO<INF>X</INF> reduced.\3\ To 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 NO<INF>X</INF> and VOC reductions. 
For non-EGUs, Delaware could not identify any cost efficient controls 
beyond those already required by the SIP; estimating that at about 
$5,000 per ton of pollutant (VOC, NO<INF>X</INF>) reduced, only a small 
amount of air 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 (NO<INF>X</INF> 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 NO<INF>X</INF> and VOCs, and because further reductions 
beyond the State's current SIP measures for NO<INF>X</INF> and VOCs are 
not economically feasible.
---------------------------------------------------------------------------

    \3\ See ``Attachment A,'' State Submittal--Delaware Section 
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 NO<INF>X</INF> 
emissions by about 375 tons per year (tpy) and VOCs by 255 tpy.
---------------------------------------------------------------------------

III. EPA Analysis

A. Cross-State Air Pollution Rule

    The CAA gives EPA a backstop role to issue federal implementation 
plans (FIPs), 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 good neighbor provision for the 2008 ozone NAAQS. 81 FR 
74504. This CSAPR Update establishes statewide NO<INF>X</INF> budgets 
for certain affected EGUs in the May-September ozone season to reduce 
the interstate transport of ozone pollution in the eastern United 
States, and thereby help downwind states and communities meet and 
maintain the 2008 ozone NAAQS.\5\ The CSAPR Update, which specifically 
focuses on reducing EGU NO<INF>X</INF> emissions, includes technical 
information and related analysis to assist states with meeting the 
requirements of section 110(a)(2)(D)(i)(I) of the CAA for the 2008 
ozone NAAQS. 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 
(PM<INF>2.5</INF>) NAAQS. The CSAPR 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 NO<INF>X</INF> 
combine in the presence of sunlight. The rate of ozone production 
can be limited by the availability of either VOCs or NO<INF>X</INF>. 
In the case of the eastern states, ozone reduction has shown to be 
more effective by reducing NO<INF>X</INF> which is why reducing 
NO<INF>X</INF> emissions is the focus of both the CSAPR Update and 
today's 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 \6\ them to the downwind air 
quality problems;
---------------------------------------------------------------------------

    \6\ In this rulemaking action, the terms ``link,'' ``linked,'' 
or ``linkage'' indicate an association or relationship between two 
entities and should not be construed as there being any type of 
physical connection.
---------------------------------------------------------------------------

    (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 in a FIP or SIP.This four-step 
framework is informed by cost-effectiveness and feasibility of 
controls, emissions, meteorology, and air quality factors. In the CSAPR 
Update, EPA used this four-step framework to determine each linked 
upwind state's significant contribution to nonattainment or 
interference with maintenance of downwind air quality.

B. EPA's Assessment of Delaware

    While EPA's CSAPR Update analysis included an assessment of 
Delaware, the State was not included in the final CSAPR Update FIPs. In 
the CSAPR Update, EPA found that steps 1 and 2 of the CSAPR framework 
linked Delaware to a downwind maintenance receptor in Philadelphia 
County, Pennsylvania. EPA applied step 3 of the CSAPR framework to 
establish EGU NO<INF>X</INF> emission budgets that reflect 
NO<INF>X</INF> reductions necessary to reduce interstate ozone 
transport for the 2008 ozone NAAQS.\7\
---------------------------------------------------------------------------

    \7\ Due to the State's sources already being equivalently 
controlled, EPA's assessment shows no cost effective EGU 
NO<INF>X</INF> reduction potential available in Delaware by the 2017 
ozone season, the implementation date for the CSAPR Update. 81 FR 
74504 (October 26, 2016).
---------------------------------------------------------------------------

    For this analysis, EPA applied a multi-factor evaluation of cost, 
NO<INF>X</INF> reductions, and air quality improvements. As part of 
this analysis, EPA explicitly evaluated whether the budget quantified 
for each state would result in over-control,\8\ as required by 
precedents of the Supreme Court and D.C. Circuit.\9\ Specifically, EPA 
evaluated whether at each level of NO<INF>X</INF> emission budget, the 
identified downwind ozone problems (i.e., nonattainment or maintenance 
problems) are resolved or the upwind contribution from any linked state 
dropped below the 1% screening threshold used to link the state. This 
multi-factor evaluation of cost, NO<INF>X</INF> reductions, and air 
quality improvements (including consideration

[[Page 44934]]

of potential over-control) resulted in EPA's quantification of upwind 
emissions that significantly contribute to nonattainment or interfere 
with maintenance of the 2008 ozone NAAQS downwind.\10\
---------------------------------------------------------------------------

    \8\ 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 
in attainment. 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).
    \9\ Id.
    \10\ CSAPR Update final rule. 81 FR 74504, 74519 (October 26, 
2016).
---------------------------------------------------------------------------

C. Air Quality Assessment Tool

    The emission reductions under the various levels of emission 
budgets analyzed by EPA can 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. In examining emissions contribution to nonattainment and 
maintenance receptors for the 2008 ozone NAAQS, EPA used the Air 
Quality Assessment Tool (AQAT) to estimate the air quality impacts of 
the upwind state EGU NO<INF>X</INF> emission budgets on downwind ozone 
pollution levels for each of the assessed EGU NO<INF>X</INF> 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 solved,\11\ 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 
emission budget level, 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.
---------------------------------------------------------------------------

    \11\ When the average and maximum design values of a receptor 
decreases to values below 76 parts per billion (ppb) or (0.076 ppm), 
the nonattainment and maintenance issues of the receptor would be 
considered solved.
---------------------------------------------------------------------------

D. Conclusion

    EPA examined emission budget levels of: $0 per ton; $800 per ton; 
$1,400 per ton; $3,400 per ton; $5,000 per ton; and $6,400 per ton.\12\ 
\13\ 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' NO<INF>X</INF> 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. 81 FR at 74553 (EPA's assessment of 
EGU NO<INF>X</INF> reduction potential shows no cost effective 
reductions available in Delaware in 2017 at any evaluated cost 
threshold because they are already equivalently controlled). Further, 
EPA estimated that implementation of the CSAPR Update along with 
NO<INF>X</INF> controls in Delaware's approved SIP are anticipated to 
resolve the lone downwind maintenance receptor to which Delaware is 
linked.\14\
---------------------------------------------------------------------------

    \12\ Due to the close timing of Pennsylvania finalizing its May 
2016 regulation ``Additional RACT Requirements for Major Sources of 
NO<INF>X</INF> and VOCs,'' also known as RACT II, to the publication 
of the CSAPR Update, EPA was not able to factor expected emission 
limits from RACT II directly into the previously concluded modeling 
for CSAPR Update when all of the other relevant in-place state and 
national rules were incorporated. EPA therefore conducted a separate 
analysis in order to incorporate the impacts of the new PA RACT 
emission limits in addition to the already incorporated national and 
state rules. The total results were incorporated into the Agency's 
assessment at each emission budget level (e.g. $0/ton through 
$6,400/ton) and at each stage of the rulemaking analysis. See 
``Pennsylvania RACT Memo to the Docket,'' Docket No. EPA-HQ-OAR-
2015-0500 for a more detailed discussion.
    \13\ Pennsylvania's RACT II provisions are part of 
Pennsylvania's strategy to meet its RACT obligations for the 2008 
ozone NAAQS. EPA has not yet taken rulemaking action on 
Pennsylvania's RACT II.
    \14\ 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 NO<INF>X</INF> reduced would resolve the maintenance 
problem at the Philadelphia, Pennsylvania maintenance receptor 
(monitor ID 4210100124).
---------------------------------------------------------------------------

    EPA evaluated EGU NO<INF>X</INF> reduction potential under the 
CSAPR Update and the assessment showed that there was no cost effective 
EGU NO<INF>X</INF> reduction potential within Delaware at any evaluated 
cost threshold because the Delaware EGUs are already equivalently 
controlled.\15\ In Delaware's March 27, 2013 submittal, in addition to 
EGUs, Delaware evaluated sources other than EGUs and the State could 
not identify any cost efficient controls for reducing VOCs or 
NO<INF>X</INF> beyond those already required by the SIP.
---------------------------------------------------------------------------

    \15\ See 81 FR at 74553.
---------------------------------------------------------------------------

    In conclusion, when evaluating all the available information, EPA 
finds that Delaware has implemented measures that have reduced 
statewide VOC and NO<INF>X</INF> 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 \16\ 
and existing NO<INF>X</INF> controls in place in Delaware. EPA finds 
Delaware has no cost effective EGU NO<INF>X</INF> emissions reduction 
potential, beyond what is already required in Delaware's SIP, at or 
below a $6,400 per ton threshold used in the CSAPR Update 
determinations by 2017 for the 2008 ozone NAAQS. Additionally, EPA 
finds that Delaware's non-EGU sources are also well-controlled and that 
there is limited VOC and NO<INF>X</INF> emissions reduction potential, 
beyond what it already required in the State's SIP, at and below the 
$5,000 per ton 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 we are 
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.
---------------------------------------------------------------------------

    \16\ EPA notes that the preliminary 2014-2016 design value for 
the identified CSAPR Update Philadelphia maintenance site does not 
reflect the air quality results as a result of the CSAPR Update 
implementation because sources began compliance with the rule in May 
1, 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) for the 2008 ozone NAAQS in 
accordance with section 110 of the CAA 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 our prior SIP approval action, published on April 3, 
2014 (79 FR 18644).
    EPA is publishing this rule without prior proposal because EPA 
views this as a noncontroversial amendment and anticipates no adverse 
comment. However, in the ``Proposed Rules'' section of this issue of 
the Federal Register, EPA is publishing a separate document that will 
serve as the proposal to approve the SIP revision if adverse comments 
are filed. This rule will be effective on December 26, 2017 without 
further notice unless EPA receives adverse comment by October 27, 2017. 
If EPA receives adverse comment, EPA will publish a timely withdrawal 
in the Federal Register informing the public that the rule will not 
take effect. EPA will address all public comments in a subsequent final 
rule based on the proposed rule. EPA will not institute a second 
comment period on this action. Any parties interested in commenting 
must do so at this time.

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:
    <bullet> 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);
    <bullet> does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
    <bullet> 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.);
    <bullet> 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);
    <bullet> does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
    <bullet> is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
    <bullet> is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
    <bullet> 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
    <bullet> 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. 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 November 27, 2017. 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. Parties with objections to this direct final rule are 
encouraged to file a comment in response to the parallel notice of 
proposed rulemaking for this action published in the proposed rules 
section of this issue of the Federal Register, rather than file an 
immediate petition for judicial review of this direct final rule, so 
that EPA can withdraw this direct final rule and address the comment in 
the proposed rulemaking 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).)
