**II. Technical Amendments**
Pharmgate LLC, 1015 Ashes Dr., suite 102, Wilmington, NC 28405, has informed FDA that it has changed its address to 1800 Sir Tyler Dr., Wilmington, NC 28405. Accordingly, we are amending § 510.600(c) to reflect this change.
We are making several technical amendments in part 558, which was amended on December 27, 2016 (81 FR 94991), and February 24, 2017 (82 FR 11510), as part of the FDA Center for Veterinary Medicine's (CVM's) Judicious Use Initiative. We are also making several technical amendments to the regulations for dosage form drugs. These actions are being taken to improve the accuracy of the regulations.
**III. Legal Authority**
This final rule is issued under section 512(i) of the Federal Food, Drug, and Cosmetic Act (the 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.”
**List of Subjects**
Administrative practice and procedure, Animal drugs, Labeling, Reporting and recordkeeping requirements.
Animal drugs.
Animal drugs, Animal feeds.
