SUPPLEMENTARY INFORMATION:

Elanco Animal Health, A Division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a supplement to NADA 141-172 that provides for use of PAYLEAN (9 or 45 grams per pound (g/lb) ractopamine hydrochloride) and TYLAN (10, 40, or 100 g/lb tylosin phosphate) Type A medicated articles to make combination drug Type C medicated feeds used for increased rate of weight gain, improved feed efficiency, and increased carcass leanness; and for the prevention of swine dysentery in finishing swine. The supplemental NADA is approved as of June 19, 2002, and the regulations are amended in § 558.500 (21 CFR 558.500) to reflect the approval. The basis of approval is discussed in the freedom of information summary.

In addition, § 558.500 is being revised to reflect a current format. The entire text of this section is being provided for the convenience of the reader.

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.
