Air Quality Criteria for Particulate Matter

AGENCY: Environmental Protection Agency.

ACTION: Call for information.

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

SUMMARY: The Environmental Criteria and Assessment Office of Health and
Environmental Assessment, of the U.S. Environmental Protection Agency
(EPA) is undertaking to update and revise, where appropriate, EPA's air
quality criteria for particulate matter (PM) under sections 108 and 109
of the Clean Air Act.
Since completion of the 1982 criteria document for particulate
matter and sulfur oxides (and its 1986 addendum), EPA has continued to
follow the scientific literature and compile information that may be
relevant to a review of the National Ambient Air Quality Standards for
PM. Interested parties are invited to assist EPA in developing and
refining its scientific information base to help ensure that all
relevant information is considered in updating the air quality criteria
for PM. Identification of new information in the following areas will
be particularly useful: Effects of exposure on laboratory animals and
humans; effects on vegetation, agroecosystems (crops), and natural
ecosystems; effects on nonbiological materials; effects on global
climate; chemistry and physics; sources and emissions; analytical
methodology; transformation and transport in the environment; and
ambient concentrations.
To be considered for inclusion in the criteria document, submitted
information should have been published, accepted for publication, or
presented at a public scientific meeting.

DATES: All communications and information should be submitted by June
30, 1994, and addressed to the Project Manager for PM, Environmental
Criteria and Assessment office (MD-52), U.S. Environmental Protection
Agency, Research Triangle Park, NC 27711.

Dated: April 5, 1994.
Gary J. Foley,
Acting Assistant Administrator for Research and Development.
