2005 Federal Register Notices by Publication Date

This page lists Federal Register notices originated by the Office of Transportation and Air Quality (OTAQ). There is no guarantee that this is a complete list, but it should contain virtually everything generated by OTAQ since 1994.  For more information on finding a particular Federal Register notice, please Contact Us.

NOTES:

  1. For state-specific SIP actions, conformity rulings, etc., search the Air Subset of the EPA's Federal Register Notices web site for the state name and action of interest (e.g., Louisiana Transportation Conformity.) This site also contains all OTAQ-related Federal Register notices.
  2. For fuel economy standards, see DOT/NHTSA rulemaking documents.
  3. All Federal Register Notices in text and Adobe Acrobat PDF format can also be found on GPO Access Web sites around the country (A list of all such sites can be found at:  Access GPO ).  Besides offering the PDF format, these also allow more search options than the EPA Web site.
  4. For Electronic Code of Federal Regulations (e-CFR)
