End Further Info End Preamble Start Supplemental Information


Alpharma Inc., One Executive Drive, P.O. Box 1399, Fort Lee, NJ 07024, filed a supplement to NADA 141-148 for use of DECCOX (decoquinate) and RUMENSIN (monensin sodium) Type A medicated articles to make two-way Type B and Type C medicated feeds for cattle at the broader range of concentrations. The supplemental application is approved as of July 30, 2004, and the regulations are amended in 21 CFR 558.195 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 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)(1) 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 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.
