ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a supplemental new animal drug application (NADA) filed by Elanco Animal Health. The supplemental NADA provides for an increased level of monensin in four-way combination Type C medicated feeds containing ractopamine, melengestrol, monensin, and tylosin for heifers fed in confinement for slaughter, a revision to bacterial pathogen nomenclature, and an increase in liver tolerance. DATES: This rule is effective October 5, 2007. FOR FURTHER INFORMATION CONTACT: Suzanne J. Sechen, Center for Veterinary Medicine (HFV-126), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-827-0221, e-mail: suzanne.sechen@cvm.fda.gov. SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a supplement to NADA 141-233 that provides for use of OPTAFLEXX (ractopamine hydrochloride), MGA (melengestrol acetate), RUMENSIN (monensin), and TYLAN (tylosin phosphate) Type A medicated articles to [[Page 56897]] make dry and liquid four-way combination Type C medicated feeds used for increased rate of weight gain, improved feed efficiency, and increased carcass leanness; for prevention and control of coccidiosis due to Eimeria bovis and E. zuernii; for suppression of estrus (heat); and for reduction of incidence of liver abscesses caused by Fusobacterium necrophorum and Arcanobacterium (Actinomyces) pyogenes in heifers fed in confinement for slaughter during the last 28 to 42 days on feed. The supplemental NADA provides for an increased level of monensin in four-way combination Type C medicated feeds containing ractopamine, melengestrol, monensin, and tylosin for heifers fed in confinement for slaughter, a revision to bacterial pathogen nomenclature, and an increase in the cattle liver tolerance. The supplemental NADA is approved as of September 11, 2007, and the regulations in 21 CFR 556.420 and 558.500 are amended to reflect the approval. In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and effectiveness data and information submitted to support approval of this application 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(a)(2) that this action is of a type that does 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.
