[[Page 12493]]

    As provided in the regulatory text of this document, the animal 
drug regulations are amended to reflect these changes of sponsorship.

III. Technical Amendments

    We are reformatting the regulations in subpart B of part 558 for 
certain medicated feeds to present their approved conditions of use in 
the current tabular format. In addition, we are removing cross-
referencing citations for indications for use of combination drug 
medicated feeds wherever they have been used and in their place are 
adding the full text of the indications. These actions are being taken 
to improve the consistency and readability of the regulations.

IV. Legal Authority

    This final rule is issued under section 512(i) of the Federal Food, 
Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 360b(i)), which requires 
Federal Register publication of ``notice[s] . . . effective as a 
regulation,'' of the conditions of use of approved new animal drugs. 
This rule sets forth technical amendments to the regulations to codify 
recent actions on approved new animal drug applications and corrections 
to improve the accuracy of the regulations, and as such does not impose 
any burden on regulated entities.
    Although denominated a rule pursuant to the FD&C Act, this document 
does not meet the definition of ``rule'' in 5 U.S.C. 804(3)(A) because 
it is a ``rule of particular applicability.'' Therefore, it is not 
subject to the congressional review requirements in 5 U.S.C. 801-808. 
Likewise, this is not a rule subject to Executive Order 12866, which 
defines a rule as ``an agency statement of general applicability and 
future effect, which the agency intends to have the force and effect of 
law, that is designed to implement, interpret, or prescribe law or 
policy or to describe the procedure or practice requirements of an 
agency.''
