Download as PDF tkelley on DSK3SPTVN1PROD with NOTICES 4694 Federal Register / Vol. 79, No. 19 / Wednesday, January 29, 2014 / Notices 002). CASAC also previously reviewed EPA’s Policy Assessment for the Review of the Ozone National Ambient Air Quality Standards (First External Review Draft—August 2012) as reported in a letter to the EPA Administrator, dated November 26, 2012 (EPA– CASAC–13–003). The CASAC Ozone Review Panel will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies. Technical Contacts: Any technical questions concerning the Health Risk and Exposure Assessment for Ozone— Second External Review Draft (January 2014) or concerning the Welfare Risk and Exposure Assessment for Ozone— Second External Review Draft (January 2014) should be directed to Dr. Bryan Hubbell (hubbell.bryan@epa.gov). Any questions concerning the Policy Assessment for the Review of the Ozone National Ambient Air Quality Standards—Second External Review Draft (January 2014) should be directed to Ms. Susan Lyon Stone (stone.susan@epa.gov). Availability of Meeting Materials: Prior to the meeting, the review documents, agenda and other materials will be accessible through the calendar link on the blue navigation bar at http:// www.epa.gov/casac/. Procedures for Providing Public Input: Public comment for consideration by EPA’s federal advisory committees and panels has a different purpose from public comment provided to EPA program offices. Therefore, the process for submitting comments to a federal advisory committee is different from the process used to submit comments to an EPA program office. Federal advisory committees and panels, including scientific advisory committees, provide independent advice to EPA. Members of the public can submit relevant comments for a federal advisory committee to consider pertaining to EPA’s charge to the committee or review materials. Input from the public to the CASAC will have the most impact if it provides specific scientific, technical information or analysis or if it relates to the clarity or accuracy of the technical information for the CASAC’s consideration. Members of the public wishing to provide comment should contact the Designated Federal Officer directly. Oral Statements: In general, individuals or groups requesting an oral presentation at a public meeting will be limited to five minutes. Interested parties should contact Dr. Stallworth, DFO, in writing (preferably via email) at the contact information noted above by March 13, 2014, to be placed on the list of public speakers for the meeting. VerDate Mar<15>2010 16:05 Jan 28, 2014 Jkt 232001 Written Statements: Written statements should be submitted to the DFO via email at the contact information noted above by March 13, 2014 for the meeting so that the information may be made available to the CASAC Panel for their consideration. Written statements should be supplied in one of the following electronic formats: Adobe Acrobat PDF, MS Word, MS PowerPoint, or Rich Text files in IBM– PC/Windows 98/2000/XP format. It is the SAB Staff Office general policy to post public comments on the Web page for the advisory meeting or teleconference. Submitters are requested to provide an unsigned version of each document because the SAB Staff Office does not publish documents with signatures on its Web sites. Members of the public should be aware that their personal contact information, if included in any written comments, may be posted to the CASAC Web site. Copyrighted material will not be posted without explicit permission of the copyright holder. Accessibility: The public can view the March 25–27, 2014 meeting via a noninteractive webcast that will be broadcast on the internet. The connection information to view the meeting via webcast will be provided on the SAB Web site at http:// www.epa.gov/casac in advance of the meeting. For information on access or services for individuals with disabilities, please contact Dr. Holly Stallworth at (202) 564–2073 or stallworth.holly@epa.gov. To request accommodation of a disability, please contact Dr. Stallworth preferably at least ten days prior to the meeting to give EPA as much time as possible to process your request.

SUPPLEMENTARY INFORMATION: I. General Information A. What should I consider as I prepare my comments for the EPA? 1. Submitting CBI. Do not submit this information to the EPA through www.regulations.gov or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI information 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 CFR part 2. 2. Tips for Preparing Your Comments. When submitting comments, remember to: • Identify the rulemaking by docket number and other identifying information (subject heading, Federal Register date and page number). • Follow directions—The agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number. • Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes. • Describe any assumptions and provide any technical information and/ or data that you used. PO 00000 Frm 00041 Fmt 4703 Sfmt 4703 4695 • 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 Specific to These Documents Two sections of the Clean Air Act (Act) 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 sources;’’ 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, if appropriate, revise the NAAQS, based on the revised air quality 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 existing criteria and standards as may be appropriate * * *.’’ Since the early 1980’s, this independent review function has been performed by the Clean Air Scientific Advisory Committee (CASAC). Presently, the EPA is reviewing the NAAQS for O3. The EPA’s overall plan E:\FR\FM\29JAN1.SGM 29JAN1 4696 Federal Register / Vol. 79, No. 19 / Wednesday, January 29, 2014 / Notices for this review is presented in the Integrated Review Plan for the Ozone National Ambient Air Quality Standards.1 As part of the EPA’s review of the primary and secondary O3 NAAQS,2 the Agency has conducted quantitative assessments characterizing the: (1) Health risks associated with exposure to ambient O3; (2) welfare risks associated with exposure to ambient O3; and, (3) associated ambient air quality analyses. On or about January 31, 2014, the EPA is making available for public comment two draft assessment documents titled, Health Risk and Exposure Assessment for Ozone, Second External Review Draft and Welfare Risk and Exposure Assessment for Ozone, Second External Review Draft. These documents revise the first draft Health Risk and Exposure Assessment (EPA– 452/P–12–001; July 2012) and first draft Welfare Risk and Exposure Assessment (EPA–452/P–12–004; July 2012), respectively.3 The draft assessment documents announced today convey the approaches taken to assess exposures to ambient O3 and to characterize associated health and welfare risks, as well as present the key results, observations, and related uncertainties associated with the quantitative analyses performed. These draft assessments may be accessed online through the EPA’s Technology Transfer Network (TTN) Web site at http:// www.epa.gov/ttn/naaqs/standards/ ozone/s_o3_index.html. In addition, on or about January 31, 2014, the EPA will make available the draft document titled, Policy Assessment for the Review of the Ozone National Ambient Air Quality Standards, Second External Review Draft. This document will serve to ‘‘bridge the gap’’ between the scientific information and the judgments required of the Administrator in determining whether to retain or revise the existing NAAQS for (O3), and, if revision is considered, what revisions may be appropriate. This document revises the first draft Policy Assessment (EPA–452/ P–12–004; July 2012).4 The Policy Assessment builds upon information presented in the Integrated Science Assessment of Ozone and Related tkelley on DSK3SPTVN1PROD with NOTICES 1 EPA 452/R–11–006; April 2011; Available: http://www.epa.gov/ttn/naaqs/standards/ozone/ data/2011_04_OzoneIRP.pdf. 2 See http://www.epa.gov/ttn/naaqs/review.html for more information on the NAAQS review process. 3 These documents were the subject of a review by the CASAC in September 2012; 77 FR 46755, August 6, 2012. 4 This document was the subject of a review by CASAC in September 2012; 77 FR 46755, August 6, 2012.

The second draft Policy Assessment may be accessed online through the EPA’s TTN Web site at: http:// www.epa.gov/ttn/naaqs/standards/ ozone/s_o3_index.html. The EPA is soliciting advice and recommendations from the CASAC by means of a review of these draft documents at an upcoming public meeting of the CASAC. Information about these public meetings, including the dates and locations, will be published as a separate notice in the Federal Register. Following the CASAC meeting, the EPA will consider comments received from the CASAC and the public in preparing revisions to these documents. The EPA will consider public comments submitted in response to this notice when revising the documents. The documents that are the subject of today’s notice do not represent and should not be construed to represent any final EPA policy, viewpoint or determination. Dated: January 22, 2014. Mary E.

II. Information Specific to These Documents

    Two sections of the Clean Air Act (Act) 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 
sources;'' 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, if appropriate, revise the NAAQS, 
based on the revised air quality 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 existing 
criteria and standards as may be appropriate * * *.'' Since the early 
1980's, this independent review function has been performed by the 
Clean Air Scientific Advisory Committee (CASAC).
    Presently, the EPA is reviewing the NAAQS for O3. The 
EPA's overall plan

[[Page 4696]]

for this review is presented in the Integrated Review Plan for the 
Ozone National Ambient Air Quality Standards.\1\ As part of the EPA's 
review of the primary and secondary O3 NAAQS,\2\ the Agency 
has conducted quantitative assessments characterizing the: (1) Health 
risks associated with exposure to ambient O3; (2) welfare 
risks associated with exposure to ambient O3; and, (3) 
associated ambient air quality analyses. On or about January 31, 2014, 
the EPA is making available for public comment two draft assessment 
documents titled, Health Risk and Exposure Assessment for Ozone, Second 
External Review Draft and Welfare Risk and Exposure Assessment for 
Ozone, Second External Review Draft. These documents revise the first 
draft Health Risk and Exposure Assessment (EPA-452/P-12-001; July 2012) 
and first draft Welfare Risk and Exposure Assessment (EPA-452/P-12-004; 
July 2012), respectively.\3\ The draft assessment documents announced 
today convey the approaches taken to assess exposures to ambient 
O3 and to characterize associated health and welfare risks, 
as well as present the key results, observations, and related 
uncertainties associated with the quantitative analyses performed. 
These draft assessments may be accessed online through the EPA's 
Technology Transfer Network (TTN) Web site at http://www.epa.gov/ttn/naaqs/standards/ozone/s_o3_index.html.

    In addition, on or about January 31, 2014, the EPA will make 
available the draft document titled, Policy Assessment for the Review 
of the Ozone National Ambient Air Quality Standards, Second External 
Review Draft. This document will serve to ``bridge the gap'' between 
the scientific information and the judgments required of the 
Administrator in determining whether to retain or revise the existing 
NAAQS for (O3), and, if revision is considered, what 
revisions may be appropriate. This document revises the first draft 
Policy Assessment (EPA-452/P-12-004; July 2012).\4\ The Policy 
Assessment builds upon information presented in the Integrated Science 
Assessment of Ozone and Related Photochemical Oxidants (Final Report) 
\5\ and the two draft assessment documents announced today and 
described above. The second draft Policy Assessment may be accessed 
online through the EPA's TTN Web site at: http://www.epa.gov/ttn/naaqs/standards/ozone/s_o3_index.html.

    The EPA is soliciting advice and recommendations from the CASAC by 
means of a review of these draft documents at an upcoming public 
meeting of the CASAC. Information about these public meetings, 
including the dates and locations, will be published as a separate 
notice in the Federal Register. Following the CASAC meeting, the EPA 
will consider comments received from the CASAC and the public in 
preparing revisions to these documents. The EPA will consider public 
comments submitted in response to this notice when revising the 
documents. The documents that are the subject of today's notice do not 
represent and should not be construed to represent any final EPA 
policy, viewpoint or determination.
