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 http:// 

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

for a copy of Administrator Jackson’s May 21, 2009 

memorandum and for additional information on the 

NAAQS review process. 

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 

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 

http://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 http://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. 

Dated: February 19, 2010.

Acting Director, Office of Air Quality Planning 

and Standards.

Environmental Impact Statements and 

Regulations; Availability of EPA 

Comments 

Availability of EPA comments 

prepared pursuant to the Environmental 

Review Process (ERP), under section 

309 of the Clean Air Act and Section 

102(2)(c) of the National Environmental 

Policy Act as amended. Requests for 

copies of EPA comments can be directed 

to the Office of Federal Activities at 

202–564–7146 or http://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: http:// 

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
