SUPPLEMENTARY INFORMATION: Section 108 (a) of the Clean Air Act directs
the Administrator to identify certain pollutants which ``may reasonably
be anticipated to endanger public health and welfare'' and to issue air
quality criteria for them. These air quality criteria are to
``accurately reflect the latest scientific knowledge useful in
indicating the kind and extent of all identifiable effects on public
health or welfare which may be expected from the presence of [a]
pollutant in the ambient air. * * *'' EPA is then to establish National
Ambient Air Quality Standards (NAAQS) for each pollutant for which EPA
has issued criteria. Section 109 (d) of the Act requires ``thorough''
periodic review and, if appropriate, revision of
[[Page 63112]]
existing air quality criteria to reflect the latest scientific data on
all identifiable effects on public health and welfare of the pollutant.
EPA is also to revise the NAAQS, if appropriate, based on the revised
criteria.
Particulate matter (PM) is one of six ``criteria'' pollutants for
which EPA has established air quality criteria and NAAQS. EPA initially
announced details of its plans for the review of the criteria and NAAQS
for PM in an October 23, 1997 Federal Register notice (62 FR 55201). As
part of its current review cycle of the PM criteria and NAAQS, EPA has
revised the existing Criteria Document for PM. The revised Criteria
Document will be publicly available on or about October 29, 2004, as
described above.
