Intervet, Inc., P.O. Box 318, 29160 Intervet Lane, Millsboro, DE 19966, filed a supplement to NADA 104-494 that provides for use of PANACUR (fenbendazole) Suspension 10% in horses for the control of various internal parasites. The supplemental NADA provides for a revised human food safety warning on product labeling. The supplemental NADA is approved as of March 25, 2009, and the regulations are amended in 21 CFR 520.905a to reflect the approval and a current format.
Approval of this supplemental NADA did not require review of additional safety or effectiveness data or information. Therefore, a freedom of information summary is not required.
The agency has determined under 21 CFR 25.33(a)(1) 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.Start List of Subjects
