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.
