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 two-way combination Type B and Type C medicated swine feeds formulated with PAYLEAN (ractopamine hydrochloride) and TYLAN (tylosin phosphate) single-Start Printed Page 41619ingredient Type A medicated articles. The supplement provides for revised indications for use of Type C medicated feeds used for increased rate of weight gain, improved feed efficiency, and increased carcass leanness; and for control of swine dysentery associated with Brachyspira hyodysenteriae and porcine proliferative enteropathies (ileitis) associated with Lawsonia intracellularis in finishing swine, weighing not less than 150 pounds (lbs), fed a complete ration containing at least 16 percent crude protein for the last 45 to 90 lbs of gain prior to slaughter. The supplemental NADA is approved as of June 20, 2007, 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.

FDA 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.
