    Ridley U.S. Holdings, Inc., 424 North Riverfront Dr., P.O. Box 
8500, Mankato, MN 56002-8500 has informed FDA that it has transferred

    Accordingly, the animal drug regulations are being amended to 
reflect these changes of sponsorship. Following these withdrawals of 
approval, neither Ridley Block Operations, Inc. nor Ridley U.S. 
Holdings, Inc. is the sponsor of an approved application. Accordingly, 
these firms will be removed from the list of sponsors of approved 
applications in Sec.  510.600(c) (21 CFR 510.600(c)).

III. 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.''

Reporting and recordkeeping requirements.
