SUPPLEMENTARY INFORMATION:

Elanco Animal Health, a Div. of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a supplement to NADA 141-172 for use of two-way combination Type B and C medicated swine feeds formulated with PAYLEAN (ractopamine hydrochloride) and TYLAN (tylosin phosphate) single-ingredient Type A medicated articles. The supplement provides use of two-way combination Type B and C medicated swine feeds formulated with ractopamine hydrochloride and tylosin phosphate following use of tylosin tartrate medicated drinking water consistent with the sequential use approved for single-ingredient tylosin medicated swine feed (73 FR 76946, December 18, 2008). The supplemental NADA is approved as of October 23, 2009, and the regulations in 21 CFR 558.500 are amended to reflect the approval.

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.

In addition, FDA has noticed that the tylosin levels for single-ingredient Type C medicated swine feed are not clearly described in 21 CFR 558.625. At this time, those regulations are being revised to clarify this use of levels. This action is being taken to improve the accuracy of the regulations.

FDA has determined under 21 CFR 25.33 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.
