SUPPLEMENTARY INFORMATION:

First Priority, Inc., 1590 Todd Farm Dr., Elgin, IL 60123, filed a supplement to ANADA 200-340 for PRIVERMECTIN (ivermectin), a topical solution used on cattle to control infestations of certain species of external and internal parasites. The supplemental ANADA Start Printed Page 26648adds 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 March 26, 2010, and 21 CFR 524.1193 is amended to reflect the approval.

In addition, FDA has noticed the regulations do not accurately reflect approved indications for generic products. At this time, the regulations are being revised to reflect which generic products have approved labeling for the durations of persistent effectiveness approved for the pioneer product. FDA is also adding a parasite species that was inadvertently omitted in the previously cited January 6, 2004, final rule. These actions are being taken to improve the accuracy of the regulations.

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 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.
