SUPPLEMENTARY INFORMATION: 

I. What is the purpose of this action?

    The purpose of this notice of availability is to solicit input from 
interested parties other than Texas on the EPA's recent response to the 
designation recommendation from Texas for the San Antonio area for the 
2015 Ozone NAAQS. This response, and the 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.
    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 agency's intended designations for the remaining 
undesignated areas, except for eight counties in the San Antonio, 
Texas, area. States and tribes were provided an opportunity during the 
120-day process to provide additional information for the EPA to 
consider in making the final designation decisions. Although not 
required, the EPA also provided a public comment period on its intended 
designations for these areas.
    On January 19, 2018, the EPA sent a follow-up letter to the 
Governor of Texas requesting any additional information that the state 
would like the EPA to consider in designating the San Antonio area. In 
a letter dated February 28, 2018, the Governor of Texas provided his 
response on the appropriate designation for the San Antonio area.
    On March 19, 2018, the EPA notified the Governor of Texas of the 
agency's intended designations for the eight

[[Page 13720]]

counties in the San Antonio area. That action initiated the 120-day 
period process specific to the eight counties in the San Antonio area. 
The EPA plans to continue to work with the state in an effort to 
resolve any disagreement regarding the designation of the eight 
counties in the San Antonio area.
    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 Texas, on the EPA's recent response to the 
designation recommendation from Texas for the eight counties in the San 
Antonio area for the 2015 Ozone NAAQS. The response, and the supporting 
technical analysis, 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 with 
respect to the 2015 Ozone NAAQS in order to gather additional 
information for the EPA to consider before making final designations. 
The EPA invites public input on our response to Texas regarding the 
designations for the San Antonio area 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 April 30, 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 FOR FURTHER INFORMATION CONTACT 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 believe 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.
