Function Responses Associated with O3

Concentrations that Just Meet the 

Current and Alternative 8-Hour Daily 

Maximum Standards—Totals and 

Portions Attributable to O3 Within 0.1 

ppm Ranges, Based on 2002 and 2004 

Air Quality Data.’’ The docket number 

for this memo is EPA–HQ–OAR–2005–

SUPPLEMENTARY INFORMATION: 

A. Background 

On July 11, 2007, EPA published a 

proposed rule to make revisions to the 

primary and secondary NAAQS for 

ozone to provide requisite protection of 

public health and welfare (72 FR 

37818). A Technical Support Document 

(TSD) was completed in July 2007 by 

Abt Associates, Inc. entitled ‘‘Ozone 

Health Risk Assessment for Selected 

Urban Areas.’’ This TSD is docket item 

EPA–HQ–OAR–2005–0172–6794. Since 

completion of the TSD, Abt Associates, 

Inc. has prepared an additional analysis 

to show the non-accidental mortality 

and lung function risk associated with 

each 0.01 ppm O3 concentration or 

exposure interval for air quality 

simulating just meeting the current and 

several alternative standards based on 

2002 and 2004 air quality data. The total 

O3-related risk for non-accidental 

mortality and specific lung function 

responses are also presented in the 

tables in this memo and are the same as 

reported in the July 2007 TSD.
