The supplemental NADAs provide for administering a Type C medicated feed containing ractopamine hydrochloride as a top dress on Type C medicated feeds containing monensin, USP, or monensin, USP, and tylosin phosphate to cattle fed in confinement for slaughter.

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a supplement to NADA 141-225 that provides for use of OPTAFLEXX (ractopamine hydrochloride) and RUMENSIN (monensin, USP) Type A medicated articles to formulate two-way combination drug Type C medicated feeds for cattle fed in confinement for slaughter. Elanco Animal Health also filed a supplement to NADA 141-224 that provides for use of OPTAFLEXX (ractopamine hydrochloride), RUMENSIN (monensin, USP), and TYLAN (tylosin phosphate) Type A medicated articles to formulate three-way combination drug Type C medicated feeds for cattle fed in confinement for slaughter. The supplemental NADAs provide for administering ractopamine hydrochloride Type C medicated feeds as a top dress on Type C medicated feeds containing monensin, USP, or monensin, USP, and tylosin phosphate to cattle fed in confinement for slaughter as the means by which the two-way or three-way combinations will be created. Supplemental NADA 141-224 is approved as of June 7, 2010; supplemental NADA 141-225 is approved as of June 17, 2010; and the regulations in 21 CFR 558.500 are amended to reflect the approvals. In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), a summaries of safety and effectiveness data and information submitted to support approval of these applications may be seen in the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday. The agency has determined under 21 CFR 25.33 that these actions are of a type that do not individually or cumulatively have a significant effect on the human environment. Therefore, neither an environmental assessment nor an environmental impact statement is required. This rule 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.
