SUPPLEMENTARY INFORMATION:

Koffolk, Inc., P.O. Box 675935, 14735 Las Quintas, Rancho Santa Fe, CA 92067, filed NADA 141-146 that provides for combining approved Nicarb® (113.5 grams per pound (g/lb) nicarbazin) manufactured by Koffolk, Inc., and Baciferm® (50 g/lb bacitracin as bacitracin zinc) manufactured by Roche Vitamins, Inc., Type A medicated articles to make Type C medicated broiler chicken feeds. The Type C broiler feeds contain 113.5 g/ton (t) nicarbazin and 4 to 50 g/t bacitracin. The Type C broiler chicken feeds are used as an aid in preventing outbreaks of cecal (Eimeria tenella) and intestinal (E. acervulina, E. maxima, E. necatrix, and E. brunetti) coccidiosis, and for increased rate of weight gain and improved feed efficiency.

The NADA is approved as of February 2, 2000, and the regulations are amended by adding 21 CFR 558.78(d)(3)(xxi) and by amending the table in 21 CFR 558.366(c) to reflect the approval. The basis for approval is discussed in the freedom of information summary.

This approval is for use of Type A medicated articles to make combination drug Type C medicated feeds. Nicarbazin is a category II drug as defined in 21 CFR 558.3(b)(1)(ii). As provided in 21 CFR 558.4(b), an approved Form FDA 1900 is required to make a Type C medicated feed from a category II drug. Under 21 U.S.C. 360b(m), as amended by the Animal Drug Availability Act of 1996 (Public Law 104-250), medicated feed applications have been replaced by a requirement for feedmill licenses. Therefore, use of Type A medicated articles to make Type C medicated feeds as provided in NADA 141-146 is limited to manufacture in a licensed feedmill.

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.
