SUPPLEMENTARY INFORMATION: IVX Animal Health, Inc., 3915 South 48th 
Street Ter., St. Joseph, MO 64503, filed a supplement to ANADA 200-286 
that provides for oral use of PHOENECTIN (ivermectin) Paste 1.87 
percent for the treatment and control of additional species of 
gastrointestinal parasites in horses. The supplemental ANADA is 
approved as of December 18, 2008, and the regulations are amended in 21 
CFR 520.1192 to reflect the approval.
    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.
