SUPPLEMENTARY INFORMATION: Fort Dodge Animal Health, Division of Wyeth Holdings Corp., P.O. Box 1339, Fort Dodge, IA 50501, filed a supplement to NADA 65-440 for AUREOMYCIN (chlortetracycline) Soluble Powder Concentrate, approved for oral use in medicated drinking water of chickens, growing turkeys, swine, calves, beef cattle, and nonlactating dairy cattle for the control and/or treatment of various bacterial diseases. The supplemental NADA provides for label revisions. The supplemental application is approved as of October 18, 2007, and the regulations are amended in 21 CFR 520.445b 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 Sec. 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.
