SUPPLEMENTARY INFORMATION: Intervet Inc., 29160 Intervet Lane, P.O. Box 
318, Millsboro, DE 19966, filed supplements to NADA 140-897 and NADA 
140-992 for REVALOR (trenbolone acetate and estradiol) implants. Ivy 
Laboratories, Division of Ivy Animal Health, Inc., 8857 Bond St., 
Overland Park, KS 66214, filed supplements to ANADA 200-221 and ANADA 
200-346 for COMPONENT (trenbolone acetate and estradiol) and COMPONENT 
plus TYLAN (trenbolone acetate and estradiol with tylosin tartrate) 
implants. Fort Dodge Animal Health, Division of Wyeth, 800 Fifth St. 
NW., Fort Dodge, IA 50501, filed a supplement to ANADA 200-367 for 
SYNOVEX (trenbolone acetate and estradiol) implants. The supplemental 
NADAs and ANADAs provide for the addition of statements to labeling 
warning against the use of these products in calves to be processed for 
veal. The supplemental applications are approved as of October 28, 
2004, and the regulations are amended in 21 CFR 522.2477 to reflect the 
approval. 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), summaries of safety and 
effectiveness data and information submitted to support approval of 
these applications 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 these 
actions are of a type that do 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.
