PURINA SAF-T-BLOC BG 520.1840 Medicated Feed Block (poloxalene, 6.6%). ------------------------------------------------------------------------ Elsewhere in this issue of the Federal Register, FDA gave notice that approval of NADAs 011-779, 040-205, 042-116, 043-215, 046-700, 091-260, 097-258, 102-942, 113-748, 135-941, 136-116, and 140-869, and all supplements and amendments thereto, is withdrawn, effective October 9, 2018. As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these actions. IV. Technical Amendments JBS United Animal Health II LLC, 322 S Main St., Sheridan, IN 46069 has informed FDA that it has changed its name to United-AH II LLC. Accordingly, we are amending Sec. 510.600(c) to reflect this change. We are also making technical amendments to update the scientific name of a pathogenic bacterium and to accurately list the concentrations of new animal drug ingredients in combination drug medicated feeds. These actions are being taken to improve the accuracy of the regulations. 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.''
