Subject

Transmittal of Provisional assessment of recent studies on health
effects of particulate matter exposure









Steve,

Attached please find the subject final report for your consideration and
inclusion in the docket for the PM NAAQS process.   As noted in the
Executive Summary, this report was prepared by ORD in response to a
commitment to assess recent publications to ensure the Administrator was
aware of new science, prior to final decisions on the NAAQS.  The
NCEA-RTP staff evaluated many hundreds of studies and have prepared a
report emphasizing epidemiologic studies conducted in the US or Canada
using PM2.5 or PM10-2.5, and toxicology and epidemiology studies
comparing effects of multiple components or sources.  A peer review of
the report was completed by four independent EPA expert scientists. 
Your staff made helpful suggestions on a draft.   We are planning to
brief Assistant Administrator Gray and Acting Assistant Administrator
Wehrum on this report on Friday, June 30.   

Please let me know if you have any questions regarding this report.

Attach the final report:
