FDA is making the following amendments to improve the accuracy of the animal drug regulations:
• 21 CFR 510.600 is amended to remove Ark Sciences, Inc., and Vetcare Oy from the list of sponsors of approved applications and to revise the address for Anivive Lifesciences, Inc. A punctuation change is made in the codified name for Veátoquinol USA, Inc.

V. 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."
