This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

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 Start Printed Page 63112existing 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.Start Signature
