SUPPLEMENTARY INFORMATION:

I. Background

Particle pollution, also referred to as particulate matter (PM), is a complex mixture of small particles and liquid droplets suspended in the air, which causes adverse health effects and is the leading cause of visibility impairment in the United States. Particles with a diameter equal to or less than 2.5 microns, referred to as fine particulate matter or PM2.5, are either emitted directly into the atmosphere or are formed from the chemical reactions of precursor gases, such as sulfur dioxide (SO2), nitrogen oxides (NOX), certain volatile organic compounds (VOCs), and ammonia, in the atmosphere. SO2 and NOX are the primary precursors for the formation of PM2.5 and are emitted primarily from point sources as well as nonpoint, onroad, and nonroad sources.

On July 18, 1997, EPA promulgated a new 24-hour and a new annual NAAQS for PM2.5 (62 FR 38652). On October 17, 2006, EPA revised the NAAQS for PM2.5, tightening the 24-hour PM2.5 standard from 65 micrograms per cubic meter (µg/m[3] ) to 35 µg/m[3] , and retaining the annual PM2.5 NAAQS at 15 µg/m[3] (71 FR 61144). Subsequently, on December 14, 2012, EPA revised the level of the health based (primary) annual PM2.5 NAAQS to 12 µg/m[3] . See 78 FR 3086 (January 15, 2013).[1]

Pursuant to section 110(a)(1), states must submit “within 3 years (or such shorter period as the Administrator may prescribe) after the promulgation of a national primary ambient air quality standard (or any revision thereof),” a plan that provides for the “implementation, maintenance, and enforcement” of such NAAQS. The statute directly imposes on states the duty to make these SIP submissions and the requirements to make the submissions is not conditioned upon EPA's taking any action other than promulgating a new or revised NAAQS. Section 110(a)(2) includes a list of specific elements that “[e]ach such plan” submission must address. EPA commonly refers to such state plans as “infrastructure SIPs.”

II. Summary of SIP Revision and EPA Analysis

On August 18, 2016, the State of Maryland, through the Maryland Department of the Environment (MDE), formally submitted a SIP revision (SIP #16-12) in order to satisfy the requirements of section 110(a) of the CAA for the 2012 PM2.5 NAAQS. The SIP submittal addressed the following infrastructure elements for the 2012 PM2.5 NAAQS: CAA section 110(a)(2)(A), (B), (C), (D)(i)(I), (D)(i)(II), D(ii), (E), (F), (G), (H), (J), (K), (L), and (M).

Maryland's infrastructure SIP submittal did not address the following two elements of CAA section 110(a)(2): The portion of section 110(a)(2)(C) pertaining to permit programs, known as nonattainment new source review (NNSR), under part D of the CAA, and section 110(a)(2)(I), referred to as “element (I),” pertaining to the nonattainment requirements of part D, title I of the CAA. According to the EPA guidance issued on September 13, 2013 (2013 Infrastructure Guidance),[2] the NNSR permitting program requirement of section 110(a)(2)(C) is to be addressed in a different SIP, and therefore does not need to be addressed in this SIP revision. Section 110(a)(2)(I) is not required to be submitted by the 3-year submission deadline of CAA section 110(a)(1) and will be addressed in a separate process if necessary.

On July 5, 2018 (83 FR 31352), EPA published a notice of proposed rulemaking (NPR) for Maryland. In the NPR, EPA proposed approval of Maryland's August 18, 2016 infrastructure SIP submittal for the 2012 PM2.5 NAAQS. A detailed summary of EPA's review and rationale for approving Maryland's submittal may be found in the Technical Support Document (TSD) for this rulemaking action, which is available online at www.regulations.gov, Docket ID Number EPA-R03-OAR-2017-0441.

III. Public Comments and EPA Response

EPA received a total of three comments on the July 5, 2018 NPR. Two of the comments did not concern any of the specific issues raised in the NPR, nor did they address EPA's rationale for the proposed approval of MDE's submittal. Therefore, EPA is not responding to those comments. EPA also received a comment that was supportive of EPA's proposed approval of Maryland's August 18, 2016 infrastructure SIP submittal for the 2012 PM2.5 NAAQS. All of the comments received are included in the docket for this action, available online at www.regulations.gov, Docket ID: EPA-R03-OAR-2017-0441.

IV. Final Action

EPA's review of Maryland's August 18, 2016 infrastructure SIP submittal for the 2012 PM2.5 NAAQS indicates that MDE's August 18, 2016 submittal satisfies the infrastructure requirements of CAA section 110(a) for the 2012 PM2.5 NAAQS.[3] EPA is approving Maryland's Start Printed Page 44484August 18, 2016 infrastructure SIP submittal for the 2012 PM2.5 NAAQS as a revision to the Maryland SIP.

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. 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 October 30, 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 approving Maryland's August 18, 2016 infrastructure SIP submittal for the 2012 PM2.5 NAAQS may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)

3.  As stated above, Maryland's infrastructure SIP submittal did not address the portion of CAA section 110(a)(2)(C) pertaining to the NNSR permitting program nor CAA section 110(a)(2)(I) pertaining to the nonattainment requirements of part D, title I of the CAA. According to the 2013 Infrastructure Guidance, the NNSR permitting program requirement of section 110(a)(2)(C) is to be addressed in a different SIP and therefore does not need to be addressed in this SIP revision. Section 110(a)(2)(I) is not required to be submitted by the 3-year submission deadline of CAA section 110(a)(1) and will be addressed in a separate process if necessary.
