Research Needed To Improve Health and Ecological Risk Assessment 
for Ozone

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability of external review draft.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of the Second External 
Review Draft of a document, Research Needed to Improve Health and 
Ecological Risk Assessment for Ozone, EPA/600/R-98/031B, prepared by 
the Office of Research and Development of the U.S. Environmental 
Protection Agency (EPA). The purpose of this document is to identify 
the scientific areas in which research is most needed to improve health 
and ecological risk assessment in the process of setting National 
Ambient Air Quality Standards for ozone. Many of the research needs 
identified and discussed in this document became apparent during 
preparation of the Air Quality Criteria for Ozone and Related 
Photochemical Oxidants, EPA/600/P-93/004aF,bF,cF, July 1996. The First 
External Review Draft of this research needs document was reviewed by 
the Clean Air Scientific Advisory Committee (CASAC)

[[Page 67525]]

of EPA's Science Advisory Board, on November 16, 1998, in Chapel Hill, 
NC. This Second External Review Draft has been prepared in light of 
CASAC's comments at that time and will be reviewed by CASAC (likely in 
March 2002), with date and location of the CASAC public review meeting 
to be announced in a future Federal Register notice. This document is 
intended to serve as a general guide to planning and conducting needed 
research on ambient ozone. The document intentionally makes no attempt 
to recommend specific research studies or programs.

DATES: Anyone who wishes to comment on this document may do so in 
writing by February 15, 2002.
