periodically review and revise the 

NAAQS, if appropriate, based on the 

revised criteria.1

Presently, EPA is reviewing the 

NAAQS for PM. The EPA’s overall plan 

and schedule for this review is 

presented in the Integrated Review Plan 

for the National Ambient Air Quality 

Standards for Particulate Matter.2 A 

draft of this integrated review plan was 

released for public review and comment 

in October 2007 and was the subject of 

a consultation with the Clean Air 

Scientific Advisory Committee (CASAC) 

on November 30, 2007 (72 FR 63177; 

November 8, 2007).3 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 and secondary PM NAAQS, the 

Agency conducted quantitative 

assessments characterizing: (1) The 

health risks associated with exposure to 

ambient PM, and (2) urban visibility 

impairment associated with ambient 

PM. The EPA’s plans for conducting 

these assessments, including the 

proposed scope and methods of the 

analyses, were presented in two 

planning documents titled, Particulate 

Matter National Ambient Air Quality 

Standards: Scope and Methods Plan for 

Health Risk and Exposure Assessment 

and Particulate Matter National 

Ambient Air Quality Standards: Scope 

and Methods Plan for Urban Visibility 

Impact Assessment (henceforth, Scope 

and Methods Plans).4 These documents 

were released for public comment in 

February 2009 and were the subject of 

a consultation with the CASAC on April 

2, 2009 (74 FR 11580; March 18, 2009). 

First and second external review 

drafts of the assessment documents 

were released for CASAC review and 

public comment in September 2009 (74 

FR 46589; September 10, 2009) and 

January/February 2010 (75 FR 4067; 

January 26, 2010), respectively, and 

were the subjects of CASAC review 

meetings in October 2009 (74 FR 46586; 

September 10, 2009) and March 2010 

(75 FR 8062; February 23, 2010), 

respectively. In preparing the final 

assessment documents, EPA has 

considered comments received from 

CASAC and the public on these earlier 

draft documents. The final assessment 

documents announced today convey the 

approaches taken to assess PM-related 

human health risks and urban visibility 

impairment, as well as present key 

results, observations, and related 

uncertainties associated with the 

quantitative analyses performed. These 

documents will be available on or about 

June 30, 2010, through the Agency’s 

Technology Transfer Network (TTN) 

Web site at http://www.epa.gov/ttn/

Release of Second Draft Document 

Related to the Review of the National 

Ambient Air Quality Standards for 

Particulate Matter 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Availability of draft document 

for public comment. 

SUMMARY: On or about June 30, 2010, the

National Ambient Air Quality 

Standards—Second External Review 

Draft. This draft document will serve to 

‘‘bridge the gap’’ between the scientific

of the Administrator in determining 

whether it is appropriate to retain or 

revise the standards as part of the 

review of the national ambient air 

quality standards (NAAQS) for 

particulate matter (PM).

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 

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.1

Presently, EPA is reviewing the 

NAAQS for PM. The EPA’s overall plan 

and schedule for this review is 

presented in the Integrated Review Plan 

for the National Ambient Air Quality 

Standards for Particulate Matter.2 A 

draft of the integrated review plan was 

released for public review and comment 

in October 2007 and was the subject of 

a consultation with the Clean Air 

Scientific Advisory Committee (CASAC) 

on November 30, 2007 (72 FR 63177; 

November 8, 2007). 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) and secondary 

(welfare-based) PM NAAQS, the Agency 

has completed the Integrated Science 

Assessment for Particulate Matter 3 and 

two quantitative assessment documents 

characterizing: (1) The health risks 

associated with exposure to ambient PM 

and (2) urban visibility impairment 

associated with PM. The two assessment 

documents are titled, Particulate Matter 

Urban-Focused Visibility Assessment 

and Quantitative Health Risk 

Assessment for Particulate Matter.4

The second draft Policy Assessment 

announced today builds on the 

scientific and technical information 

available in this review as assessed in 

the Integrated Science Assessment and 

the two quantitative assessment 

documents identified above. This 

document presents factors relevant to 

EPA’s review of the primary and 

secondary PM NAAQS. It focuses on 

both evidence- and risk-based 

information in evaluating the adequacy 

of the current PM NAAQS and 

identifying potential alternative 

standards for consideration. The second 

draft Policy Assessment may be 

accessed online on or about June 30, 

2010, through EPA’s TTN Web site at 

http://www.epa.gov/ttn/naaqs/ 

standards/pm/s_pm_2007_pa.html. 

The EPA is soliciting advice and 

recommendations from the CASAC by 

means of a review of the second draft 

Policy Assessment at an upcoming 

public meeting of the CASAC that will 

be held on July 26–27, 2010 (75 FR 

32763; June 9, 2010). Following the 

CASAC meeting, EPA will consider 

comments received from the CASAC 

and the public in preparing a final 

Policy Assessment. 

The draft document described above 

does not represent and should not be 

construed to represent any final EPA 

policy, viewpoint, or determination.
