FOR FURTHER INFORMATION CONTACT: Lonnie W. Luther, Center for 
Veterinary Medicine (HFV-101), Food and Drug Administration, 7500

SUPPLEMENTARY INFORMATION: First Priority, Inc., 1585 Todd Farm Dr., 
Elgin, IL 60123, filed ANADA 200-327 for PRIVERMECTIN (ivermectin) 
Drench for Sheep. The application provides for oral use of a 0.08 
percent ivermectin solution in sheep for the treatment and control of 
various internal parasites. First Priority's PRIVERMECTIN Drench for 
Sheep is approved as a generic copy of Merial Limited's IVOMEC Drench 
for Sheep, approved under NADA 131-392. ANADA 200-327 is approved as of 
May 15, 2002, and the regulations are amended in Sec. 520.1195 (21 CFR 
520.1195) to reflect the approval. The basis of approval is discussed 
in the freedom of information summary. Section 520.1195 is also being 
amended to correctly describe the concentration of the product and to 
incorporate 21 CFR 520.1194 in a current format.
    In accordance with the freedom of information provisions of 21 CFR 
part 20 and 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 Dockets Management Branch (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 congressional review requirements in 5 
U.S.C. 801-808.

List of Subjects in 21 CFR Part 520

    Animal drugs.

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

amended as follows:
