End Further Info End Preamble Start Supplemental Information


Novartis Animal Health US, Inc., 3200 Northline Ave., suite 300, Greensboro, NC 27408, filed a supplement to NADA 140-916 for DENAGARD (tiamulin) Liquid Concentrate administered in drinking water for the treatment of certain bacterial respiratory and enteric diseases in swine. The supplemental NADA provides for use of a 12.5 percent tiamulin concentrate solution. The supplemental NADA is approved as of June 14, 2010, and 21 CFR 520.2455 is amended to reflect the approval.

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 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.
