SUPPLEMENTARY INFORMATION:

Elanco Animal Health, A Division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a supplemental application to NADA 140-929 that provides for the use of MICOTIL 300 (tilmicosin phosphate) Injection by subcutaneous injection for the treatment of ORD associated with Mannheimia (Pasteurella) haemolytica. The supplemental NADA is approved as of September 4, 2002, and the regulations are amended in 21 CFR 522.2471 and § 556.735 (21 CFR 556.735) to reflect the approval. The basis of approval is discussed in the freedom of information summary.

In addition, § 556.735 is amended by adding a tolerance for residues of tilmicosin in sheep muscle and liver and in cattle muscle, and editorially, to reflect a current format.

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 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(d)(4) 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.
