Melanie R. Berson, Center for Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-827-7540, e-mail: mberson@cvm.fda.gov .
SUPPLEMENTARY INFORMATION:
Intervet, Inc., P.O. Box 318, 405 State St., Millsboro, DE 19966, filed a supplement to NADA 131-675 that provides for the use of SAFE-GUARD (fenbendazole) 20% Type A medicated article to make Type B and Type C medicated horse feeds. The medicated feeds are used for the control of large strongyles ( Strongylus edentatus , S. equinus , S. vulgaris , Triodontophorus spp.), small strongyles ( Cyathostomum spp., Cylicocyclus spp., Cylicostephanus spp.), pinworms ( Oxyuris equi ), and ascarids ( Parascaris equorum ) in horses. The NADA is approved as of March 14, 2003 , and the regulations are amended in 21 CFR 558.258 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), 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.
Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and Cosmetics Act (21 U.S.C. 360b(c)(2)(F)(iii)), this approval qualifies for 3 years of marketing exclusivity beginning March 14, 2003.
The agency has determined under § 25.33(d)(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.
