the use of other reductants, in addition 

to current aqueous urea DEF, and will 

reexamine requisite infrastructure 

needs, any issues regarding the emission 

of unregulated pollutants, and any 

potential safety concerns. EPA is 

conducting the workshop with the 

California Air Resources Board in order 

that all relevant information be timely 

shared and considered by all affected 

parties; however, any final policies 

reached by EPA will be independently 

made and based upon applicable federal

Air Resources Board regarding this

Do not submit information that you 

consider to be CBI or otherwise 

protected through http:// 

www.regulations.gov or e-mail. The 

http://www.regulations.gov Web site is

If you send an e-mail comment directly 

to EPA without going through http:// 

www.regulations.gov, your e-mail 

address will be automatically captured 

and included as part of the comment 

that is placed in the public docket and 

made available on the Internet. If you 

submit an electronic comment, EPA 

recommends that you include your 

name and other contact information in 

the body of your comment and with any 

disk or CD–ROM you submit. If EPA 

cannot read your comment due to 

technical difficulties and cannot contact

Persons with comments containing 

proprietary information must 

distinguish such information from other 

comments to the greatest possible extent 

and label it as ‘‘Confidential Business 

Information’’ (CBI). If a person making 

comments wants EPA to base its 

decision in part on a submission labeled 

as CBI, then a non-confidential version 

of the document that summarizes the 

key data or information should be 

submitted for the public docket. To 

ensure that proprietary information is 

not inadvertently placed in the docket, 

submissions containing such 

information should be sent directly to 

the contact person listed above and not 

to the public docket. Information

Release of Final Documents Related to 

the Review of the National Ambient Air 

Quality Standards for Particulate 

Matter 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of Availability. 

SUMMARY: The Office of Air Quality 

Planning and Standards (OAQPS) of 

EPA is announcing the availability of 

two final documents titled, Quantitative 

Health Risk Assessment for Particulate 

Matter and Particulate Matter UrbanFocused Visibility Assessment. These 

two documents describe the quantitative 

analyses that have been conducted as 

part of the review of the national 

ambient air quality standards (NAAQS) 

for particulate matter (PM). 

DATES: These documents will be 

available on or about June 30, 2010. 

ADDRESSES: The documents will be 

available primarily via the Internet at 

the following Web site: http:// 

www.epa.gov/ttn/naaqs/standards/pm/ 

s_pm_2007_risk.html.

questions related to the final document 

titled, Quantitative Health Risk 

Assessment for Particulate Matter,

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 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/
