General Information A. What Should I Consider as I Prepare My Comments for EPA? 1. Submitting CBI. Do not submit this information to EPA through https:// 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. SUPPLEMENTARY INFORMATION: 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 E:\FR\FM\05MRN1.SGM 05MRN1 erowe on DSK5CLS3C1PROD with NOTICES Federal Register / Vol. 75, No. 43 / Friday, March 5, 2010 / Notices issues air quality criteria for these 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 quantities.’’ Under section 109 of the CAA, EPA establishes primary (healthbased) and secondary (welfare-based) NAAQS for pollutants for which air quality criteria are issued. 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. Presently, EPA is reviewing the air quality criteria and NAAQS for CO. The EPA’s overall plan and schedule for this review is presented in the Plan for Review of the National Ambient Air Quality Standards for Carbon Monoxide.1 A draft of this integrated review plan was released for public review and comment in March 2008 and was the subject of a consultation with the Clean Air Scientific Advisory Committee (CASAC) on April 8, 2008 (73 FR 12998). Comments received from that consultation and from the public were considered in finalizing the plan and in beginning the review of the air quality criteria. As part of EPA’s review of the primary (health-based) CO NAAQS, the Agency is conducting qualitative and quantitative assessments characterizing the health risks associated with exposure to ambient CO. The EPA’s plans for conducting these assessments, including the proposed scope and methods of the analyses, were presented in a planning document titled, Carbon Monoxide National Ambient Air Quality Standards: Scope and Methods Plan for Health Risk and Exposure Assessment (Scope and Methods Plan). This planning document was released for public comment in April 2009 and was the subject of a consultation with the CASAC on May 13, 2009 (74 FR 15265). The draft exposure and risk assessment document announced today conveys the approaches taken to assess exposures to ambient CO and to characterize associated health risks, as 1 EPA 452R–08–005; August 2008; Available: https://www.epa.gov/ttn/naaqs/standards/co/ s_co_cr_pd.html.

An earlier draft of the exposure and risk assessment document was released for CASAC review and public comment in October 2009 (74 FR 55843; October 29, 2009), and was the subject of a CASAC review meeting on November 16 and 17, 2009 (74 FR 54042). This draft document will be available on or about February 22, 2010, through the Agency’s Technology Transfer Network (TTN) Web site at https://www.epa.gov/ttn/naaqs/ standards/co/s_co_index.html. This document may be accessed in the ‘‘Documents from Current Review’’ section under ‘‘Risk and Exposure Assessments.’’ In addition, on or about March 1, 2010, EPA will make available a second draft document: Policy Assessment for the Review of the Carbon Monoxide National Ambient Air Quality Standards: External Review Draft. The development of this document is a result of recent changes to the NAAQS review process which included reinstating a policy assessment document that contains staff analyses of the scientific bases for alternative policy options for consideration by senior Agency management prior to rulemaking. This document, which builds upon the historical ‘‘Staff Paper,’’ will serve to ‘‘bridge the gap’’ between the scientific information and the judgments required of the Administrator in determining whether it is appropriate to retain or revise the standards. In conjunction with this change, EPA will no longer issue a policy assessment in the form of an Advance Notice of Proposed Rulemaking (ANPR).2 The draft Policy Assessment (PA) builds upon information presented in the Integrated Science Assessment for Carbon Monoxide and the draft assessment document described above. This draft document will be available on or about March 1, 2010, through the Agency’s Technology Transfer Network (TTN) Web site at https://www.epa.gov/ ttn/naaqs/standards/co/ s_co_index.html. This document may be accessed in the ‘‘Documents from Current Review’’ section under ‘‘Policy Assessments.’’ The EPA is soliciting advice and recommendations from the CASAC by means of a review of both draft documents at an upcoming public meeting of the CASAC.

Requests for copies of EPA comments can be directed to the Office of Federal Activities at 202–564–7146 or https://www.epa.gov/ compliance/nepa/. An explanation of the ratings assigned to draft environmental impact statements (EISs) was published in FR dated July 17, 2009 (74 FR 34754). Notice In accordance with Section 309(a) of the Clean Air Act, EPA is required to make its comments on EISs issued by other Federal agencies public. Historically, EPA has met this mandate by publishing weekly notices of availability of EPA comments, which includes a brief summary of EPA’s comment letters, in the Federal Register. Since February 2008, EPA has been including its comment letters on EISs on its Web site at: https:// www.epa.gov/compliance/nepa/ eisdata.html. Including the entire EIS comment letters on the Web site satisfies the Section 309(a) requirement to make EPA’s comments on EISs available to the public. Accordingly, after March 31, 2010, EPA will discontinue the publication of this notice of availability E:\FR\FM\05MRN1.SGM 05MRN1

SUPPLEMENTARY INFORMATION: 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

[[Page 10253]]

issues air quality criteria for these 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 quantities.'' Under section 
109 of the CAA, EPA establishes primary (health-based) and secondary 
(welfare-based) NAAQS for pollutants for which air quality criteria are 
issued. 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.
    Presently, EPA is reviewing the air quality criteria and NAAQS for 
CO. The EPA's overall plan and schedule for this review is presented in 
the Plan for Review of the National Ambient Air Quality Standards for 
Carbon Monoxide.\1\ A draft of this integrated review plan was released 
for public review and comment in March 2008 and was the subject of a 
consultation with the Clean Air Scientific Advisory Committee (CASAC) 
on April 8, 2008 (73 FR 12998). Comments received from that 
consultation and from the public were considered in finalizing the plan 
and in beginning the review of the air quality criteria.

---------------------------------------------------------------------------

    As part of EPA's review of the primary (health-based) CO NAAQS, the 
Agency is conducting qualitative and quantitative assessments 
characterizing the health risks associated with exposure to ambient CO. 
The EPA's plans for conducting these assessments, including the 
proposed scope and methods of the analyses, were presented in a 
planning document titled, Carbon Monoxide National Ambient Air Quality 
Standards: Scope and Methods Plan for Health Risk and Exposure 
Assessment (Scope and Methods Plan). This planning document was 
released for public comment in April 2009 and was the subject of a 
consultation with the CASAC on May 13, 2009 (74 FR 15265).
    The draft exposure and risk assessment document announced today 
conveys the approaches taken to assess exposures to ambient CO and to 
characterize associated health risks, as well as present the initial 
key results, observations, and related uncertainties associated with 
the quantitative analyses performed. An earlier draft of the exposure 
and risk assessment document was released for CASAC review and public 
comment in October 2009 (74 FR 55843; October 29, 2009), and was the 
subject of a CASAC review meeting on November 16 and 17, 2009 (74 FR 
54042). This draft document will be available on or about February 22, 
2010, through the Agency's Technology Transfer Network (TTN) Web site 
at https://www.epa.gov/ttn/naaqs/standards/co/s_co_index.html. This 
document may be accessed in the ``Documents from Current Review'' 
section under ``Risk and Exposure Assessments.''
    In addition, on or about March 1, 2010, EPA will make available a 
second draft document: Policy Assessment for the Review of the Carbon 
Monoxide National Ambient Air Quality Standards: External Review Draft. 
The development of this document is a result of recent changes to the 
NAAQS review process which included reinstating a policy assessment 
document that contains staff analyses of the scientific bases for 
alternative policy options for consideration by senior Agency 
management prior to rulemaking. This document, which builds upon the 
historical ``Staff Paper,'' will serve to ``bridge the gap'' between 
the scientific information and the judgments required of the 
Administrator in determining whether it is appropriate to retain or 
revise the standards. In conjunction with this change, EPA will no 
longer issue a policy assessment in the form of an Advance Notice of 
Proposed Rulemaking (ANPR).\2\

Administrator Jackson's May 21, 2009 memorandum and for additional 
information on the NAAQS review process.
---------------------------------------------------------------------------

    The draft Policy Assessment (PA) builds upon information presented 
in the Integrated Science Assessment for Carbon Monoxide and the draft 
assessment document described above. This draft document will be 
available on or about March 1, 2010, through the Agency's Technology 
Transfer Network (TTN) Web site at https://www.epa.gov/ttn/naaqs/standards/co/s_co_index.html. This document may be accessed in the 
``Documents from Current Review'' section under ``Policy Assessments.''
    The EPA is soliciting advice and recommendations from the CASAC by 
means of a review of both draft documents at an upcoming public meeting 
of the CASAC. Information about this public meeting, including the date 
and location, will be published as a separate notice in an upcoming 
edition of the Federal Register. Following the CASAC meeting, EPA will 
consider comments received from the CASAC and the public in preparing 
revisions to these documents.
    The draft documents briefly described above do not represent and 
should not be construed to represent any final EPA policy, viewpoint, 
or determination. The EPA will consider any public comments submitted 
in response to this notice when revising the documents.
