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 a new animal drug application (NADA) filedby Elanco Animal Health. The NADA provides for use of approved narasin/nicarbazin and bambermycins Type A medicated articles to make three-way combination Type C medicated feeds used for prevention of coccidiosis, increased rate of weight gain, and improved feed efficiency in broiler chickens.

DATES: This rule is effective May 16, 2001.

FOR FURTHER INFORMATION CONTACT: Charles J. Andres, Center for Veterinary Medicine (HFV-128), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-827-1600.

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filedNADA 140-942 that provides for use of Maxiban(36 grams per pound (g/lb) each of narasin and nicarbazin) and Flavomycin(2, 4, or 10 g/lb of bambermycins activity) Type A medicated articles to make three-way combination Type C medicated feeds for use in broiler chickens. The combination Type C medicated feeds contain 27 to 45 g/ton narasin and 27 to 45 g/ton nicarbazin (in a fixed 1:1 ratio) and 1 to 2 g/ton bambermycins, and are used for prevention of coccidiosis caused by Eimeria tenella, E. necatrix, E. acervulina, E. brunetti, and E. mivati, and for increased rate of weight gain and improved feed efficiency. The NADA is approved as of March 8, 2001, and the regulations are amended in 21 CFR 558.95 and 558.363 to reflect the approval. The basis of approval is discussed in the freedom of information summary

In accordance with the freedom of information provisions of 21 CFR part 20 and 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 Dockets Management Branch (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.
