Federal Register :: National Ambient Air Quality Standards for Ozone

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.

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.
