**SUPPLEMENTARY INFORMATION:**
Pennfield Oil Co., 14040 Industrial Rd., Omaha, NE 68144, has requested that FDA withdraw approval of NADA 128-550 for ANCHOR Zinc Bacitracin Type A medicated article because the product is not manufactured or marketed.
In a notice published elsewhere in this issue of the *Federal Register* , FDA gave notice that approval of NADA 128-550 and all supplements and amendments thereto, are withdrawn, effective August 28, 2007. As provided in the regulatory text of this document, the animal drug regulations are amended to reflect the withdrawal of approval.
