**ACTION:**
Final rule.
**SUMMARY:**
The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect the withdrawal of approval of a new animal drug application (NADA) for an arsanilic acid Type A medicated article at the sponsor's request because the product is no longer manufactured or marketed.
**DATES:**
Withdrawal of approval is effective December 6, 2013.
**FOR FURTHER INFORMATION CONTACT:**
John Bartkowiak, Center for Veterinary Medicine (HFV-212), Food and Drug Administration, 7519 Standish Pl., Rockville, MD 20855, 240-276-9079, email: *[email protected]* .
**SUPPLEMENTARY INFORMATION:**
Fleming Laboratories, Inc., P.O. Box 34384, Charlotte, NC 28234 has requested that FDA withdraw approval of NADA 008-019 for PRO-GEN (arsanilic acid) Type A medicated article because the product, used to manufacture Type B and Type C medicated feeds, is no longer manufactured or marketed.
Elsewhere in this issue of the *Federal Register* , FDA gave notice that approval of NADA 008-019, and all supplements and amendments thereto, is withdrawn, effective December 6, 2013. As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these voluntary withdrawals of approval.
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.
