SUPPLEMENTARY INFORMATION:

Alpharma, Inc., One Executive Dr., P.O. Box 1399, Fort Lee, NJ 07024, filed NADA 141-156 that provides for use of Amprol® (25 percent amprolium) and BMD® (10, 25, 30, 40, 50, 60, or 75 grams per pound bacitracin methylene disalicylate) Type A medicated articles to make combination Type C medicated feeds containing 36.3 to 113.5 grams per ton (g/ton) amprolium and 4 to 50 g/ton bacitracin methylene disalicylate for use in replacement chickens. The Type C medicated feeds are used for the development of active immunity to coccidiosis, increased rate of weight gain, and improved feed efficiency in replacement chickens. The NADA is approved as of February 12, 2001, and 21 CFR 558.55 is amended 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.
