SUPPLEMENTARY INFORMATION: Hoechst Roussel Vet, 30 Independence Blvd., 
P.O. Box 4915, Warren, NJ 07059, filed NADA 141-129 that provides for 
combining approved single ingredient Avatec (lasalocid) and 
Flavomycin (bambermycins) Type A medicated articles to make 
Type C medicated broiler feeds containing 68 to 113 grams per ton (g/t) 
lasalocid and 1 to 2 g/t bambermycins. The Type C medicated broiler 
feeds are used for prevention of coccidiosis caused by Eimeria tenella, 
E. necatrix, E. acervulina, E. brunetti, E. mivati, and E. maxima, and 
for increased rate of weight gain and improved feed efficiency in 
broiler chickens. The NADA is approved as of August 6, 1999, and the 
regulations are amended in 21 CFR 558.95 by adding paragraph 
(d)(1)(xiv) and in 21 CFR 558.311 by adding paragraph (e)(4)(ii) to 
reflect the approval.
    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)(2) 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.

List of Subjects in 21 CFR Part 558

    Animal drugs, Animal feeds.
    Therefore, under the Federal Food, Drug, and Cosmetic Act and under 
authority delegated to the Commissioner of Food and Drugs and 
redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is 
amended as follows:
