21 CFR Part 558

[Docket No. FDA-2011-N-0003]


New Animal Drugs for Use in Animal Feeds; Monensin

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a supplemental new animal drug 
application (NADA) filed by Elanco Animal Health, A Division of Eli 
Lilly & Co. The supplemental NADA revises a manufacturing specification 
for monensin free-choice Type C medicated feed for growing cattle on 
pasture or in dry lot.

DATES: This rule is effective December 21, 2011.

FOR FURTHER INFORMATION CONTACT: Matthew A. Lucia, Center for 
Veterinary Medicine (HFV-128), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, (240) 276-8116, email: 
matthew.lucia@fda.hhs.gov.

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli 
Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a 
supplement to NADA 95-735 that provides for use of RUMENSIN 90 
(monensin, USP) Type A medicated article in a free-choice Type C 
medicated feed for growing cattle on pasture or in dry lot (stocker and 
feeder cattle and dairy and beef replacement heifers). The supplement 
revises the percent monensin Type A medicated article in the codified 
free-choice feed specifications to reflect use of a product containing 
90.7 grams of monensin per pound. The supplemental NADA is approved as 
of May 24, 2011, and the regulations in 21 CFR 558.355 are 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

[[Page 79065]]

that does not individually or cumulatively have a significant effect on 
the human environment. Therefore, neither an environmental assessment 
nor 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.

List of Subjects in 21 CFR Part 558

    Therefore, under the Federal Food, Drug, and Cosmetic Act and under
