III. Technical Amendments

FDA is making the following amendments to improve the accuracy of the animal drug regulations:

• 21 CFR 516.498 is removed from subpart C of part 516 and is added to subpart E.

• 21 CFR 520.370, 520.522, 522.246, 522.304, 522.2470, 524.1044c, 524.1044f, and 524.1484g are amended to reflect a sponsor's current drug labeler code.

• 21 CFR 520.441 is amended to revise the sponsor listings for uses of chlortetracycline in drinking water of various food-producing animals.

• 21 CFR 520.443 is amended to revise the sponsor listings for uses of chlortetracycline tablets and boluses in calves.

• 21 CFR 520.1196 is amended to revise the indication for uses of ivermectin and pyrantel tablets in dogs.

• 21 CFR 522. 1660a is amended to reflect the correct drug labeler code for a sponsor of an oxytetracycline injectable solution.

[top] • 21 CFR 558.355 is amended to revise a caution statement on labeling of monensin Type A medicated articles for use in broiler breeder replacement chickens.

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."
