the animal drug regulations:

sponsors of approved applications. The entries for Mylan Institutional, 
Inc. and Norbrook Laboratories Ltd. are revised as well.
     21 CFR 516.812 is amended to reflect a current drug 
labeler code for a use of enrofloxacin injectable solution in cattle.
     21 CFR 520.88g is amended reflect a current sponsor drug 
labeler code and revised indications for use of tablets containing 
amoxicillin and clavulanate in dogs and cats.
     21 CFR 520.530 is amended to conform to content codified 
for animal drugs available by veterinary prescription.
     21 CFR 520.905a is amended to reflect revised conditions 
of use for fenbendazole suspension in horses.
     21 CFR 520.928 is amended to reflect correct directions

for use of a levamisol powder in cattle and sheep.
     21 CFR 520.1720a is amended to correct an error in the

VI. 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.''
