I. What is the purpose of this action?

The purpose of this notice of availability is to solicit input from interested parties other than states and tribes on the EPA's recent responses to the state and tribal designation recommendations for the 2015 Ozone NAAQS. These responses, and their supporting technical analyses, can be found at https://www.epa.gov/​ozone-designations and in the public docket for these ozone designations at https://www.regulations.gov under Docket ID No. EPA-HQ-OAR-2017-0548.

On October 1, 2015, the EPA Administrator signed a notice of final rulemaking that revised the primary and secondary ozone NAAQS (80 FR 65292; October 26, 2015). The EPA established the revised primary and secondary ozone NAAQS at 0.070 parts per million (ppm). The 2015 Ozone NAAQS are met at an ambient air quality monitoring site when the 3-year average of the annual fourth highest daily maximum 8-hour average ozone concentration (i.e., the design value) is less than or equal to 0.070 ppm. The revised standards will improve public health protection, particularly for at-risk groups including children, older adults, people of all ages who have lung diseases such as asthma, and people who are active outdoors, especially outdoor workers. They also will improve the health of trees, plants and ecosystems.

After the EPA promulgates a new or revised NAAQS, the Clean Air Act (CAA) requires the EPA to designate all areas of the country as either “Nonattainment,” “Attainment,” or “Unclassifiable,” for that NAAQS. The process for these initial designations is contained in CAA section 107(d)(1) (42 U.S.C. 7407). After promulgation of a new or revised NAAQS, each governor or tribal leader has an opportunity to recommend air quality designations, including the appropriate boundaries for Nonattainment areas, to the EPA. The EPA considers these recommendations as part of its duty to promulgate the formal area designations and boundaries for the new or revised NAAQS. By no later than 120 days prior to promulgating designations, the EPA is required to notify states, territories, and tribes, as appropriate, of any intended modifications to an area designation or boundary recommendation that the EPA deems necessary.

On November 6, 2017, the EPA established initial air quality designations for most areas in the United States, including most areas of Indian country, for the 2015 primary and secondary ozone NAAQS 82 FR 54232, November 16, 2017). In that action, the EPA designated 2,646 counties, including Indian country located in those counties, two separate areas of Indian country, and five territories as Attainment/Unclassifiable and three counties as Unclassifiable.

This current action provides the EPA's intended designation of all remaining undesignated areas. On or about December 20, 2017, consistent with section 107(d)(1)(b)(ii) of the CAA, the EPA notified affected states and tribes of the remaining recommended designations.[1] While the EPA is in agreement with the recommendations for most areas, the EPA indicated that in some instances it intended to modify a state or tribal recommends. States and tribes have the opportunity during the 120-day process to provide additional information for the EPA to consider in making the final designation decisions. We stand ready to assist and hope to resolve any differences regarding the proper designation for all remaining areas within the 120-day process provided by the CAA.

Once designations take effect, they govern what subsequent regulatory actions states, tribes, and the EPA must take in order to improve or preserve air quality in each area.

II. Instructions for Submitting Public Comments and Internet Website for Rulemaking Information

A. Invitation To Comment

The purpose of this notice is to solicit input from interested parties, other than the states and tribes to which we have sent notification letters, on the EPA's recent responses to the designation recommendations for the 2015 Ozone NAAQS. These responses, and their supporting technical analyses, can be found at https://www.epa.gov/​ozone-designations and in the public docket for these ozone designations at Docket ID No. EPA-HQ-OAR-2017-0548. The EPA Docket Office can be contacted at (202) 566-1744, and is located at EPA Docket Center Reading Room, WJC West Building, Room 3334, 1301 Constitution Avenue NW, Washington, DC 20004. The hours of operation at the EPA Docket Center are 8:30 a.m.-4:30 p.m., Monday-Friday.

CAA section 107(d)(1) provides a process for air quality designations that involves recommendations by states, territories, and tribes to the EPA and responses from the EPA to those parties, prior to the EPA promulgating final area designations and boundaries. The EPA is not required under the CAA section 107(d)(1) to seek public comment during the designation process, but we are electing to do so for these areas with respect to the 2015 Ozone NAAQS in order to gather additional information for the EPA to consider before making final designations for the specific areas addressed in the EPA's recent letters to states and tribes. The EPA invites public input on our responses to states and tribes regarding these areas during the 30-day comment period provided in this notice. In order to receive full consideration, input from the public must be submitted to the docket by February 5, 2018. This notice and opportunity for public comment does not affect any rights or obligations of any state, or tribe, or of the EPA, which might otherwise exist pursuant to the CAA section 107(d).

Please refer to the ADDRESSES section in this document for specific instructions on submitting comments and locating relevant public documents.

In establishing Nonattainment area boundaries for a particular area, CAA section 107(d)(1)(A) requires the EPA to include within the boundaries both the area that does not meet the standard and any nearby area contributing to ambient air quality in the area that does not meet the NAAQS. We are particularly interested in receiving comments, supported by relevant information addressing the section 107(d)(1)(A) criteria, if you believe that a specific geographic area should not be categorized as Nonattainment, or if you Start Printed Page 653believe that an area the EPA had indicated that it intends to designate as Attainment/Unclassifiable or Unclassifiable should in fact be categorized Nonattainment based on the presence of a violating monitor in the area or based on contribution to ambient air quality in a nearby areas. Please be as specific as possible in supporting your views.

  • Describe any assumptions and provide any technical information and/or data that you used.
  • Provide specific examples to illustrate your concerns, and suggest alternatives.
  • Explain your views as clearly as possible.
  • Provide your input by the comment period deadline identified.

The EPA intends to complete designations for all of the areas addressed in the responses to the states and tribes no later than April 30, 2018. This would complete the designation process for the 2015 Ozone NAAQS.

B. What should I consider as I prepare my comments for the EPA?

1. Submitting CBI. Do not submit CBI information to the EPA through https://www.regulations.gov or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI in a disk or CD ROM that you mail to the EPA, mark the outside of the disk or CD ROM as CBI and then identify electronically within the disk or CD ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 Code of Federal Regulations (CFR) part 2. Send or deliver information identified as CBI only to the following address: Tiffany Purifoy, OAQPS CBI Officer, U.S. EPA, Office of Air Quality Planning and Standards, Mail Code C404-02, Research Triangle Park, NC 27711, telephone (919) 541-0878, email at purifoy.tiffany@epa.gov, Attention Docket ID No. EPA-HQ-OAR-2017-0548.

  • Identify the rulemaking by docket number and other identifying information (subject heading, Federal Register date and page number).
  • Follow directions.
  • Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.

C. Where can I find additional information for this rulemaking?

The EPA has also established a website for this rulemaking at https://www.epa.gov/​ozone-designations. The website includes the state, territorial and tribal recommendations, the EPA's intended area designations, information supporting the EPA's preliminary designation decisions, the EPA's designation guidance for the 2015 Ozone NAAQS as well as the rulemaking actions and other related information that the public may find useful.
