    Alpharma Inc., One Executive Dr., P.O. Box 1399, Fort Lee, NJ 07024, filed NADA 141-148 that provides for use of DECCOX® (27.2 gram per pound (g/lb) decoquinate) and Rumensin® (20, 30, 45, 60, 80, or 90.7 g/lb monensin activity as monensin sodium) Type A medicated articles to make two-way combination Type B and Type C medicated feeds. The Type C medicated feeds contain 13.6 to 27.2 g/ton decoquinate and 5 to 30 g/ton monensin, and are used for prevention of coccidiosis caused by Eimeria bovis and E. zuernii, and improved feed efficiency in cattle fed in confinement for slaughter. The NADA is approved as of November 16, 2000, and the regulations in 21 CFR 558.195 and 558.355 are amended to reflect the approval. The basis for 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.
