drug regulations to reflect approval of a supplemental abbreviated new 
animal drug application (ANADA) filed by Norbrook Laboratories, Ltd. 
The supplemental ANADA adds claims for persistent effectiveness against 
various species of external and internal parasites when cattle are 
treated with a topical solution of ivermectin.

DATES:  This rule is effective February 12, 2007.

FOR FURTHER INFORMATION CONTACT:  John K. Harshman, Center for 
Veterinary Medicine (HFV-104), Food and Drug Administration, 7500

SUPPLEMENTARY INFORMATION: Norbrook Laboratories, Ltd., Station Works, 
Newry BT35 6JP, Northern Ireland, filed a supplement to ANADA 200-272 
for Ivermectin Pour-On for Cattle. The supplemental ANADA adds claims 
for persistent effectiveness against various species of external and 
internal parasites that were approved for the pioneer product with 3 
years of marketing exclusivity (69 FR 501, January 6, 2004). The 
supplemental ANADA is approved as of January 19, 2007, and 21 CFR 
524.1193 is amended 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.
    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 congressional review requirements in 5 
U.S.C. 801-808.
