SUPPLEMENTARY INFORMATION:

Alpharma, Inc., One Executive Dr., P.O. Box 1399, Fort Lee, NJ 07024, filed a supplement to NADA 96-298 that provides for the use of Avatec® (lasalocid sodium) Premix, a Type A medicated article. The supplement provides for establishing tolerances for residues of lasalocid in edible tissues of chickens and turkeys. The supplement is approved as of February 20, 2001, and the regulations in § 556.347 (21 CFR 556.347) are amended to reflect the approval. The basis of approval is discussed in the freedom of information summary.

In addition, the agency is taking the opportunity to codify the acceptable daily intake (ADI) for total residues of lasalocid which was previously established, and to establish a tolerance for residues of lasalocid in sheep liver. The regulations are further amended in § 556.347 to reflect these actions.

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)(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 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.
