SUMMARY: The National Center for Environmental Assessment of the U.S. 
Environmental Protection Agency (EPA) announces a public meeting to 
review draft chapters of a forthcoming EPA document entitled, Air 
Quality Criteria for Particulate Matter. This meeting will discuss the 
following topics as they pertain to particulate matter (PM) as an air 
pollutant: atmospheric chemistry, sources and emissions, concentrations 
in ambient air, exposure, epidemiology, dosimetry, toxicology, and 
controlled human exposure.

DATES: The meeting is open to the public and will be held April 6-9, 
1999, from 8:30 a.m. to 5:00 p.m., daily. To accommodate seating for

SUPPLEMENTARY INFORMATION: The U.S. Environmental Protection Agency 
(EPA) is updating and revising, where appropriate, the EPA's Air 
Quality Criteria for Particulate Matter (PM). Sections 108 and 109 of 
the Clean Air Act require that the EPA carry out a periodic review and 
revision, where appropriate, of the criteria and the National Ambient 
Air Quality Standards (NAAQS) for the ``criteria'' air pollutants such 
as PM.
    The Agency will consider the discussions at the April 6-9 meeting 
in further revisions of the draft chapters prior to their incorporation 
into an external review draft of the revised Air Quality Criteria for 
Particulate Matter and will release the draft document for public 
review and comment in July or August 1999. The Clean Air Scientific 
Advisory Committee (CASAC) will meet to review the external review 
draft document in November or December 1999. This meeting will be open 
to the public, and interested parties will have an opportunity to make 
statements. Through subsequent Federal Register notices, the EPA will 
keep the public informed of opportunities to comment on the first 
external review draft and to make statements at the CASAC review 
meeting.

    Dated: March 15, 1999.

Acting Director, National Center for Environmental Assessment.
