The agency may ask you to respond to specific questions or organize comments by reference a Code of Federal Regulations (CFR) part or section number. • Explain why you agree or disagree; suggest alternative and substitute language for your requested changes. • Describe any assumption and provide any technical information and/ or data that you used. • If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced. • Provide specific examples to illustrate your concerns and suggest alternatives. • Explain your views as clearly as possible, avoiding the use of profanity or personal threats. • Make sure to submit your comments by the comment period deadline identified. II. Information About the Document Two sections of the Clean Air Act (CAA) govern the establishment and revision of the NAAQS. Section 108 (42 U.S.C. 7408) directs the Administrator to identify and list certain air pollutants and then to issue air quality criteria for those pollutants. The Administrator is to list those air pollutants that in her ‘‘judgment, cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare;’’ ‘‘the presence of which in the ambient air results from numerous or diverse mobile or stationary source;’’ and ‘‘for which * * *. [the Administrator] plans to issue air quality criteria * * *. ’’ Air quality criteria are intended to ‘‘accurately reflect the latest scientific knowledge useful in indicating the kind and extent of all identifiable effects on public health or welfare which may be expected from the presence of [a] pollutant in the ambient air * * *. ’’ (42 U.S.C. 7408(b)). Under section 109 (42 U.S.C. 7409), the EPA establishes primary (health-based) and secondary (welfare-based) NAAQS for pollutants for which air quality criteria PO 00000 Frm 00022 Fmt 4703 Sfmt 4703 27305 are issued. Section 109(d) requires periodic review and, if appropriate, revision of existing air quality criteria. The revised air quality criteria reflect advances in scientific knowledge on the effects of the pollutant on public health or welfare. The EPA is also required to periodically review and revise the NAAQS, if appropriate, based on the revised criteria. Section 109(d)(2) requires that an independent scientific review committee ‘‘shall complete a review of the criteria * * *. and the national primary and secondary ambient air quality standards * * *. and shall recommend to the Administrator any new * * *. standards and revisions of the existing criteria and standards as may be appropriate * * *. .’’ Since the early 1980s, this independent review function has been performed by the CASAC. Presently, the EPA is reviewing the primary NAAQS for NO2. The first draft Integrated Science Assessment for Oxides of Nitrogen (Health Criteria) (ISA) was released on November 22, 2013 (78 FR 70040), and the draft Integrated Review Plan for the Primary NAAQS for Nitrogen Dioxide (IRP) (79 FR 7184) was released on February 10, 2014. Both documents were reviewed by CASAC at a public meeting in March 2014, and announced in a separate notice (79 FR 8701). The final IRP was released in June 2014 (79 FR 36801), and is available at https://www.epa.gov/ ttn/naaqs/standards/nox/s_nox_2012_ pd.html. The second draft ISA was made available to both CASAC and the public on January 29, 2015 (80 FR 5110). The REA Planning Document considers the degree to which important uncertainties identified in quantitative analyses from previous reviews have been addressed by newly available scientific evidence, tools, or information, including those in the second draft ISA. Based on these considerations, the document reaches preliminary conclusions on the extent to which updated quantitative analyses of exposures or health risks are warranted in the current review. For updated analyses that are supported, this planning document presents anticipated approaches to conducting such analyses and, where appropriate, preliminary results. This document is available on the EPA’s Technology Transfer Network Web site at https://www.epa.gov/ttn/ naaqs/standards/nox/s_nox_2012_ pd.html. The REA Planning Document has been made available for review by CASAC and for public comment. Comments should be submitted to the docket, as described above.

deadline identified.

II. Information About the Document

    Two sections of the Clean Air Act (CAA) govern the establishment 
and revision of the NAAQS. Section 108 (42 U.S.C. 7408) directs the 
Administrator to identify and list certain air pollutants and then to 
issue air quality criteria for those pollutants. The Administrator is 
to list those air pollutants that in her ``judgment, cause or 
contribute to air pollution which may reasonably be anticipated to 
endanger public health or welfare;'' ``the presence of which in the 
ambient air results from numerous or diverse mobile or stationary 
source;'' and ``for which * * *. [the Administrator] plans to issue air 
quality criteria * * *. '' Air quality criteria are intended to 
``accurately reflect the latest scientific knowledge useful in 
indicating the kind and extent of all identifiable effects on public 
health or welfare which may be expected from the presence of [a] 
pollutant in the ambient air * * *. '' (42 U.S.C. 7408(b)). Under 
section 109 (42 U.S.C. 7409), the EPA establishes primary (health-
based) and secondary (welfare-based) NAAQS for pollutants for which air 
quality criteria are issued. Section 109(d) requires periodic review 
and, if appropriate, revision of existing air quality criteria. The 
revised air quality criteria reflect advances in scientific knowledge 
on the effects of the pollutant on public health or welfare. The EPA is 
also required to periodically review and revise the NAAQS, if 
appropriate, based on the revised criteria. Section 109(d)(2) requires 
that an independent scientific review committee ``shall complete a 
review of the criteria * * *. and the national primary and secondary 
ambient air quality standards * * *. and shall recommend to the 
Administrator any new * * *. standards and revisions of the existing 
criteria and standards as may be appropriate * * *. .'' Since the early 
1980s, this independent review function has been performed by the 
CASAC.
    Presently, the EPA is reviewing the primary NAAQS for 
NO2. The first draft Integrated Science Assessment for 
Oxides of Nitrogen (Health Criteria) (ISA) was released on November 22, 
2013 (78 FR 70040), and the draft Integrated Review Plan for the 
Primary NAAQS for Nitrogen Dioxide (IRP) (79 FR 7184) was released on 
February 10, 2014. Both documents were reviewed by CASAC at a public 
meeting in March 2014, and announced in a separate notice (79 FR 8701). 
The final IRP was released in June 2014 (79 FR 36801), and is available 
at https://www.epa.gov/ttn/naaqs/standards/nox/s_nox_2012_pd.html. The 
second draft ISA was made available to both CASAC and the public on 
January 29, 2015 (80 FR 5110).
    The REA Planning Document considers the degree to which important 
uncertainties identified in quantitative analyses from previous reviews 
have been addressed by newly available scientific evidence, tools, or 
information, including those in the second draft ISA. Based on these 
considerations, the document reaches preliminary conclusions on the 
extent to which updated quantitative analyses of exposures or health 
risks are warranted in the current review. For updated analyses that 
are supported, this planning document presents anticipated approaches 
to conducting such analyses and, where appropriate, preliminary 
results. This document is available on the EPA's Technology Transfer 
Network Web site at https://www.epa.gov/ttn/naaqs/standards/nox/s_nox_2012_pd.html.
