The NADA provides for use of single-ingredient Type A medicated articles containing semduramyicin (as semduramicin sodium biomass) and virginiamycin to manufacture 2-way combination drug Type C medicated feeds for use in broiler chickens.

SUPPLEMENTARY INFORMATION:
Phibro Animal Health, 65 Challenger Rd., 3d floor, Ridgefield Park, NJ 07660, filed NADA 141-289 that provides for the use of AVIAX II (semduramicin sodium biomass) and STAFAC (virginiamycin) Type A medicated articles to manufacture 2-way combination drug Type C medicated feeds for broiler chickens. The NADA is approved as of July 13, 2009, and the regulations are amended in 21 CFR 558.555 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.
The agency 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.
List of Subjects in 21 CFR Part 558
