21 CFR Part 558


New Animal Drugs For Use in Animal Feeds; Monensin

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule; technical amendment.

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

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. The supplemental NADA 
provides for minor revisions to labeling of monensin Type A medicated 
articles for chickens. FDA is also amending the regulations to simplify 
the organization of special labeling requirements for formulations 
(Type A medicated articles, Type B and Type C medicated feeds) 
containing monensin for poultry and game birds. This action is being 
taken to improve the clarity of the regulations.

DATES: This rule is effective March 1, 2007.

Veterinary Medicine (HFV-130), Food and Drug Administration, 7500

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli 
Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a 
supplement to NADA 38-878 that provides for use of COBAN 60 and COBAN 
90 (monensin, USP) Type A medicated articles in feed of chickens. The 
supplement provides for minor revisions to labeling. The supplemental 
NADA is approved as of February 7, 2007, and the regulations in 21 CFR 
558.355 are amended to reflect the approval.
    In addition, FDA is taking this opportunity to amend the 
regulations to simplify the organization of special labeling 
requirements for formulations (Type A medicated articles, Type B and 
Type C medicated feeds) containing monensin for poultry and game birds. 
Similar restructuring was done recently for monensin formulations used 
in ruminants (71 FR 66231, November 14, 2006). This action is being 
taken to improve the clarity of the regulations.
    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.
    FDA has determined under 21 CFR 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.
