[Docket No. FDA-2010-N-0002]

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of two supplemental new animal 
drug applications (NADAs) filed by Elanco Animal Health, A Division of 
Eli Lilly & Co. 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.

DATES: This rule is effective September 3, 2010.

FOR FURTHER INFORMATION CONTACT:  Suzanne J. Sechen, Center for 
Veterinary Medicine (HFV-126), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8105, e-mail: 
suzanne.sechen@fda.hhs.gov.

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.
