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.

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 Start Printed Page 63438the 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.
