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

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 Ivy Laboratories, Division of Ivy Animal 
Health, Inc. The supplemental NADA provides for the addition of 
statements to labeling of subcutaneous implants containing estradiol 
warning against the use of these products in calves to be processed for 
veal.

DATES: This rule is effective November 22, 2004.

FOR FURTHER INFORMATION CONTACT: Eric S. Dubbin, Center for Veterinary 
Medicine (HFV-126), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-827-0232, e-mail: <a href="/cdn-cgi/l/email-protection#c0a5a4b5a2a2a9ae80a3b6adeea6a4a1eea7afb6"><span class="__cf_email__" data-cfemail="bedbdacbdcdcd7d0feddc8d390d8dadf90d9d1c8">[email protected]</span></a>.

SUPPLEMENTARY INFORMATION: Ivy Laboratories, Division of Ivy Animal 
Health, Inc., 8857 Bond St., Overland Park, KS 66214, filed a 
supplement to NADA 118-123 for ENCORE (estradiol) and COMPUDOSE 
(estradiol). The supplemental NADA provides for the addition of 
statements to labeling warning against the use of these products in 
calves to be processed for veal. The supplemental application is 
approved as of October 28, 2004, and the regulations are amended in 21 
CFR 522.840 to reflect the approval and a current format. The basis of 
approval is discussed in the freedom of information summary.
    In accordance with the freedom of information provisions of 21 CFR 
part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and 
effectiveness data and information submitted to support approval of 
this application may be seen in the Division of Dockets Management 
(HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, 
Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday.
    The agency 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.
