I. Background and Purpose

On September 27, 2018 (83 FR 48765), the EPA published a Notice of Proposed Rulemaking (NPRM) to approve the June 16, 2017 submittal from the State of New Hampshire as meeting the interstate transport requirements of CAA section 110(a)(2)(D)(i)(I) for the 2010 SO2 NAAQS. An explanation of the CAA requirements, a detailed analysis of the State's submittal, and the EPA's rationale for approval of the submittal were provided in the NPRM, and will not be restated here. The public comment period for this proposed rulemaking ended on October 29, 2018. The EPA received one comment from an anonymous commenter. The anonymous comment lacked specificity to New Hampshire's SIP submittal and the interstate transport requirements of CAA section 110(a)(2)(D)(i)(I) as they relate to the 2010 SO2 NAAQS. A response to the anonymous comment is provided in the Response to Comments section.

II. Response to Comments

Comment: The commenter stated that emissions of SO2 can undergo chemical reactions in the atmosphere to form fine particle matter, and that fine particulate matter can travel great distances affecting regional air quality and public health. The commenter stated that the transport of SO2 and fine particulate matter across state borders, referred to as “interstate air pollution transport,” makes it difficult for downwind states to meet health-based air quality standards. The commenter stated the CAA's “good neighbor” provision requires the EPA and states to address, through state implementation plans (SIPs), interstate transport of air pollution that significantly contributes to nonattainment or interferes with maintenance of a NAAQS in a downwind area in another state. The commenter asserted that New Hampshire must prove this SIP revision addresses and meets the obligations of the interstate transport requirements of the CAA respective to the 2010 SO2 NAAQS. The commenter concluded, “To meet these obligations they must prove that the interstate transport requirements for all NAAQS pollutants prohibit any state from emitting any air pollutant in amounts that will contribute significantly to nonattainment, or interfere with maintenance, of the NAAQS in another state.”

Response: The commenter did provide some general information about the formation of fine particulate matter from SO2, but did not provide specific information to support not approving New Hampshire's June 16, 2017 submittal. Fine particulate matter, generally referring to particulate matter (PM) with aerodynamic diameter less than or equal to 2.5 micrometers (PM2.5), can travel great distances. PM2.5 can be emitted directly or formed secondarily through chemical transformation in the atmosphere involving a variety of precursor pollutants, including SO2. The EPA has addressed interstate transport of PM2.5, including secondarily-formed PM2.5, through a separate action related to New Hampshire's SIP submittal for the 2012 PM2.5 infrastructure SIP. The EPA proposed to approve a revision to the New Hampshire SIP that included the provisions related to transport for the 2012 PM2.5 NAAQS on April 10, 2018 (83 FR 15343); EPA took action in a final rule to approve the New Hampshire SIP provisions related to interstate transport and other elements for the 2012 PM2.5 NAAQS on December 4, 2018 (83 FR 62464).

It is unclear what the commenter intended in the quoted final sentence of the comment. If the commenter meant to note that the CAA generally imposes an obligation that the state's interstate transport SIP for a new or revised NAAQS adequately meets the good neighbor provision for that NAAQS, we agree and believe that the New Hampshire SO2 interstate transport SIP submittal meets these CAA obligations, as stated in our NPRM. Alternatively, if the commenter meant that this SO2 interstate transport SIP must address transport for all NAAQS, we disagree.

The EPA interprets the CAA to require each state to demonstrate that it Start Printed Page 64471meets the “good neighbor” provisions of the CAA for a new or revised NAAQS for any of the six criteria air pollutants (carbon monoxide, lead, nitrogen dioxide, ozone, particle pollution, and sulfur dioxide). Particularly, CAA section 110(a)(1) requires states, three years after the promulgation of a NAAQS, to submit a plan that meets the requirements of 110(a)(2), which includes the interstate transport requirements of 110(a)(2)(D)(i)(I), for “such” NAAQS. The EPA believes the specification of “such” in relation to a particular NAAQS under 110(a)(1) narrows the state's obligation to submit an interstate transport SIP for that specific NAAQS, rather than requiring the state to demonstrate that its transport SIP is intended to address a particular NAAQS also meets the interstate transport requirements for all NAAQS. The EPA assesses each state's interstate transport SIP demonstration on a pollutant by pollutant basis, and for pollutants that result from both primary emissions and secondary (i.e., chemical) formation, the EPA does assess both primary and secondary impacts. Because SO2 does not form secondarily in the atmosphere, only an analysis of primary emissions is necessary. The EPA's NPRM to approve New Hampshire's June 16, 2017 submittal provided a weight-of-evidence analysis that addressed the “good neighbor” provision of the CAA. The EPA's assessment of New Hampshire's analysis presented in the NPRM proposed to find that the SIP revision sufficiently addresses that New Hampshire will not significantly contribute to nonattainment of the 1-hour SO2 NAAQS or interfere maintenance of the SO2 NAAQS in another state. The commenter does not point to any specific alleged flaw or gap in the EPA's assessment.

Therefore, the EPA is not making any changes to its proposed action based on the comments submitted by the commenter.

III. Final Action

The EPA is approving New Hampshire's June 16, 2017 transport SIP submission for the 2010 SO2 NAAQS as a revision to the New Hampshire SIP.

IV. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act 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 Clean Air Act. 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);
  • This action is not an Executive Order 13771 regulatory action because this action is not significant 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 (Public Law 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 Clean Air Act; 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, 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 and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

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).

Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by February 15, 2019. 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 may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
