[EPA-R03-OAR-2013-0492; FRL-9901-82-Region 3]


Approval and Promulgation of Air Quality Implementation Plans; 
Delaware; Infrastructure Requirements for the 2010 Sulfur Dioxide 
National Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) 
submittal from the State of Delaware pursuant to the Clean Air Act 
(CAA). Whenever new or revised national ambient air quality standards 
(NAAQS) are promulgated, the CAA requires states to submit a plan for 
the implementation, maintenance, and enforcement of such NAAQS. The 
plan is required to address basic program elements, including, but not 
limited to, regulatory structure, monitoring, modeling, legal 
authority, and adequate resources necessary to assure attainment and 
maintenance of the standards. These elements are referred to as 
infrastructure requirements. Delaware has made a submittal addressing 
the infrastructure requirements for the 2010 sulfur dioxide 
(SO2) NAAQS. This action proposes to approve portions of 
this submittal.

DATES: Written comments must be received on or before November 25, 
2013.

SUPPLEMENTARY INFORMATION: On May 29, 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) of the CAA for the 2010 
SO2 NAAQS.

I. Background

    On June 22, 2010 (75 FR 35520), EPA promulgated a revised NAAQS for 
the 1-hour primary SO2 at a level of 75 parts per billion 
(ppb), based on a 3-year average of the annual 99th percentile of 1-
hour daily maximum concentrations. Pursuant to section 110(a)(1) of the 
CAA, states are required to submit SIPs meeting the applicable 
requirements of section 110(a)(2) within three years after promulgation 
of a new or revised NAAQS or within such shorter period as EPA may 
prescribe. Section 110(a)(2) requires states to address basic SIP 
elements such as requirements for monitoring, basic program 
requirements and legal authority that are designed to assure attainment 
and maintenance of the NAAQS. Section 110(a) imposes the obligation 
upon states to make a SIP submittal to EPA for a new or revised NAAQS, 
but the contents of that submittal may vary depending upon the facts 
and circumstances. In particular, the data and analytical tools 
available at the time the state develops and submits the SIP for a new 
or revised NAAQS affect the content of the submittal. The content of 
such SIP submittal may also vary depending upon what provisions the 
state's existing SIP already contains.
    In the case of the 2010 SO2 NAAQS, states typically have 
met the basic program elements required in section 110(a)(2) through 
earlier SIP submittals in connection with the SO2 NAAQS. 
More specifically, section 110(a)(1) provides the procedural and timing 
requirements for SIPs. Section 110(a)(2) lists specific elements that 
states must meet for ``infrastructure'' SIP requirements related to a 
newly established or revised NAAQS. As mentioned above, these 
requirements include basic SIP elements such as requirements for 
monitoring, basic program requirements and legal authority that are 
designed to assure attainment and maintenance of the NAAQS.

II. Summary of State Submittal

    On May 29, 2013, Delaware provided a submittal to satisfy section 
110(a)(2) requirements of the CAA, that is the subject of this proposed 
rulemaking, for

[[Page 63438]]

the 2010 SO2 NAAQS. This submittal addressed the following 
infrastructure elements: section 110(a)(2)(A), (B), (C), (D), (E), (F), 
(G), (H), (J), (K), (L), and (M).
    EPA has analyzed the above identified submittal and is proposing to 
make a determination that such submittal meets the requirements of 
section 110(a)(2)(A), (B), (C), (D)(i)(II), (D)(ii), (E), (F), (G), 
(H), (J), (K), (L), and (M) of the CAA, with the exception of the part 
D, Title I nonattainment planning requirements of section 110(a)(2)(I) 
and the portion of the submittal relating to section 110(a)(2)(D)(i)(I) 
on which EPA will take separate action. A detailed summary of EPA's 
review and rationale for approving Delaware's submittal may be found in 
the Technical Support Document (TSD) for this action which is available 
on line at www.regulations.gov, Docket ID Number EPA-R03-OAR-2013-0492.
    This proposed rulemaking action does not include section 
110(a)(2)(I) which pertains to the nonattainment planning requirements 
of part D, Title I of the CAA, because this element is not required to 
be submitted by the 3-year submission deadline of section 110(a)(1) of 
the CAA, and will be addressed in a separate process. This proposed 
rulemaking action also does not address section 110(a)(2)(D)(i)(I) of 
the CAA. In accordance with the decision of the U.S. Court of Appeals 
for the District of Columbia (D.C. Circuit Court), EPA at this time is 
not treating the 110(a)(2)(D)(i)(I) SIP submission from Delaware as a 
required SIP submission. See EME Homer City Generation, L.P. v. EPA, 
696 F .3d 7 (D.C. Cir. 2012), cert. granted, 2013 U.S. Lexis 4801 
(2013). On June 24, 2013, the Supreme Court granted the petitions of 
the United States and others and agreed to review this D.C. Circuit 
Court decision. However, at this time the D.C. Circuit Court decision 
remains in place and unless it is reversed or otherwise modified by the 
Supreme Court, states are not required to submit 110(a)(2)(D)(i)(I) 
SIPs until EPA has quantified their obligations under that section. EPA 
will address the portion of Delaware's May 29, 2013 SIP submittal 
addressing section 110(a)(2)(D)(i)(I) in a separate action.

III. Proposed Action

    EPA is proposing to approve Delaware's submittal that provides the 
basic program elements specified in section 110(a)(2)(A), (B), (C), 
(D)(i)(II), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M), 
necessary to implement, maintain, and enforce the 2010 SO2 
NAAQS, with the exception of the part D, Title I nonattainment planning 
requirements of section 110(a)(2)(I) and the portion of the submittal 
relating to section 110(a)(2)(D)(i)(I) on which EPA will take separate 
action. EPA is soliciting public comments on the issues discussed in 
this document. These comments will be considered before taking final 
action.

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 proposes to approve state law as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by state law. For that reason, this proposed 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 proposed rule, pertaining to Delaware's section 
110(a)(2) infrastructure requirements for the 2010 SO2 
NAAQS, 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.
