Do not submit this information to EPA through www.regulations.gov or e-mail. 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 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. • 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. • Make sure to submit your comments by the comment period deadline identified. Under section 108(a) of the Clean Air Act (CAA), the Administrator identifies and lists certain pollutants which ‘‘cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare.’’ The EPA then issues air quality criteria for listed pollutants, which are commonly referred to as ‘‘criteria pollutants.’’ The air quality criteria are 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, in varying E:\FR\FM\12MRN1.SGM 12MRN1 srobinson on DSKHWCL6B1PROD with NOTICES 11878 Federal Register / Vol. 75, No. 48 / Friday, March 12, 2010 / Notices quantities.’’ Under section 109 of the CAA, EPA establishes national ambient air quality standards (NAAQS) for each listed pollutant, with the NAAQS based on the air quality criteria. Section 109(d) of the CAA 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. The EPA is currently conducting a joint review of the existing secondary (welfare-based) NAAQS for oxides of nitrogen (NOX) and oxides of sulfur (SOX). Because NOX, SOX, and their associated transformation products are linked from an atmospheric chemistry perspective as well as from an environmental effects perspective, and because of the National Research Council’s 2004 recommendations to consider multiple pollutants in forming the scientific basis for the NAAQS, EPA has decided to jointly assess the science, risks, and policies relevant to protecting the public welfare associated with NOX and SOX. This is the first time since NAAQS were established in 1971 that a joint review of these two pollutants has been conducted. Since both the CASAC and EPA have recognized these interactions historically, and the science related to these interactions has continued to evolve and grow to the present day, there is a strong basis for considering them together. As part of this review of the current secondary (welfare-based) NAAQS for NOX and SOX, EPA’s OAQPS staff are preparing a first draft Policy Assessment. The objective of this assessment is to evaluate the policy implications of the key scientific information contained in the document Integrated Science Assessment for Oxides of Nitrogen and SulfurEcological Criteria (https:// cfpub.epa.gov/ncea/cfm/ recordisplay.cfm?deid=201485), prepared by EPA’s National Center for Environmental Assessment (NCEA) and the results from the analyses contained in the Risk and Exposure Assessment for Review of the Secondary National Ambient Air Quality Standards for Oxides of Nitrogen and Oxides of Sulfur (https://www.epa.gov/ttn/naaqs/ standards/no2so2sec/cr_rea.html).

A. What Should I Consider as I Prepare My Comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through 
www.regulations.gov or e-mail. 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 EPA, mark the outside of the disk or CD-ROM as

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.
     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.
     Make sure to submit your comments by the comment period 
deadline identified.
    Under section 108(a) of the Clean Air Act (CAA), the Administrator 
identifies and lists certain pollutants which ``cause or contribute to 
air pollution which may reasonably be anticipated to endanger public 
health or welfare.'' The EPA then issues air quality criteria for 
listed pollutants, which are commonly referred to as ``criteria 
pollutants.'' The air quality criteria are 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, in

quantities.'' Under section 109 of the CAA, EPA establishes national 
ambient air quality standards (NAAQS) for each listed pollutant, with 
the NAAQS based on the air quality criteria. Section 109(d) of the CAA 
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.
    The EPA is currently conducting a joint review of the existing 
secondary (welfare-based) NAAQS for oxides of nitrogen (NOX) 
and oxides of sulfur (SOX). Because NOX, 
SOX, and their associated transformation products are linked 
from an atmospheric chemistry perspective as well as from an 
environmental effects perspective, and because of the National Research 
Council's 2004 recommendations to consider multiple pollutants in 
forming the scientific basis for the NAAQS, EPA has decided to jointly 
assess the science, risks, and policies relevant to protecting the 
public welfare associated with NOX and SOX. This 
is the first time since NAAQS were established in 1971 that a joint 
review of these two pollutants has been conducted. Since both the CASAC 
and EPA have recognized these interactions historically, and the 
science related to these interactions has continued to evolve and grow 
to the present day, there is a strong basis for considering them 
together.
    As part of this review of the current secondary (welfare-based) 
NAAQS for NOX and SOX, EPA's OAQPS staff are 
preparing a first draft Policy Assessment. The objective of this 
assessment is to evaluate the policy implications of the key scientific 
information contained in the document Integrated Science Assessment for 
Oxides of Nitrogen and Sulfur-Ecological Criteria (https://cfpub.epa.gov/ncea/cfm/recordisplay.cfm?deid=201485), prepared by EPA's 
National Center for Environmental Assessment (NCEA) and the results 
from the analyses contained in the Risk and Exposure Assessment for 
Review of the Secondary National Ambient Air Quality Standards for 
Oxides of Nitrogen and Oxides of Sulfur (https://www.epa.gov/ttn/naaqs/standards/no2so2sec/cr_rea.html). The first draft Policy Assessment 
will be available online at: https://www.epa.gov/ttn/naaqs/standards/no2so2sec/. This first draft Policy Assessment will be 
reviewed by the CASAC during a public meeting to be held April 1 and 2, 
2010. Information about this public meeting will be available at https://yosemite.epa.gov/sab/sabpeople.nsf/WebCommittees/CASAC.
