Workshop for External Peer Review of Draft Document on Ambient 
Sources and Noncancer Respiratory Effects of Inhaled Silica

agency: Environmental Protection Agency.

action: Notice of public meeting.

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

summary: An external peer review workshop will be held by the 
Environmental Criteria and Assessment Office (ECAO) of EPA's Office of 
Health and Environmental Assessment. Expert peer reviewers, recognized 
for their contributing to the scientific literature on silica, will 
discuss a review draft of the document entitled ``Ambient Sources and 
Noncancer Respiratory Effects of Inhaled Silica.'' The results of the 
meeting will be used in the preparation of the final document.

dates: The workshop will be held on Monday, November 14, 1994, from 
9:00 a.m. to 5:00 p.m. in Classroom 2 at EPA's Environmental Research 
Center at the intersection of Alexander Drive and Highway 54, in 
Research Triangle Park, NC. The workshop is open to the public.

for further information contact: Dr. Jeffrey S. Gift, project officer, 
U.S. Environmental Protection Agency, ECAO, MD-52, Research Triangle 
Park, NC 27711 (telephone [phone]; FAX [phone]).

supplementary information: In the development of this assessment 
document, the scientific literature relating to ambient levels and 
noncancer respiratory effects of silica has been reviewed, and key 
studies evaluated. The main objective of the document is to assess the 
available data on effect levels and concentration-response 
relationships for inhaled silica and to place them in perspective with 
observed or estimated environmental silica levels. This document does 
not review the potential carcinogenicity of silica, nor does it 
extensively address effects of particulate matter exposures that are 
not silica-specific. The draft document will be made available to the 
public at the time of the workshop. Members of the public will have an 
opportunity at the workshop to make brief, oral statements. Interested 
parties also are invited to assist the EPA in developing and refining 
the scientific information base for silica by submitting new 
information on the topics covered. To be considered for inclusion in 
the review process, submitted information should be published or 
accepted for publication in a peer-reviewed, scientific journal. New 
information should be submitted through Dr. Jeffrey Gift at the address 
indicated above.

    Dated: November 11, 1994.
Carl R. Gerber,
Acting Assistant Administrator for Research and Development.
