SUPPLEMENTARY INFORMATION:

Alpharma, Inc., One Executive Dr., P.O. Box 1399, Fort Lee, NJ 07024, filed NADA 141-155 that provides for use of BMD® (10, 25, 30, 40, 50, 60, or 75 grams per pound (g/lb) BMD), ROBENZ® (30 g/lb robenidine hydrochloride), and 3-NITRO® (45.4, 90, 227, or 360 g/lb roxarsone) Type A medicated articles to make three-way combination Type C medicated feeds containing 30 g/ton robenidine hydrochloride, 22.7 to 45.4 g/ton roxarsone, and 50 or 100 to 200 g/ton BMD for use in broiler chickens.

The combination Type C medicated feeds containing 50 g/ton BMD are used for prevention of coccidiosis caused by Eimeria tenella, E. necatrix, E. acervulina, E. brunetti, E. mivati, and E. maxima; for increased rate of weight gain, improved feed efficiency, and improved pigmentation in broiler chickens; and as an aid in the prevention of necrotic enteritis caused or complicated by Clostridium spp. or other organisms susceptible to bacitracin. The combination Type C medicated feeds containing 100 to 200 g/ton BMD are used for prevention of coccidiosis caused by E. tenella, E. necatrix, E. acervulina, E. brunetti, E. mivati, and E. maxima; for increased rate of weight gain, improved feed efficiency, and improved pigmentation in broiler chickens; and as an aid in the control of necrotic enteritis caused or complicated by Clostridium spp. or other organisms susceptible to bacitracin. The NADA is approved as of July 3, 2000, and the regulations are amended in §§ 558.76 and 558.515 (21 CFR 558.76 and 558.515) to reflect the approval. The basis of approval is discussed in the freedom of information summary.

Section 558.76 is also amended editorially to consolidate the cross-references for approved combinations in paragraph (d)(3) and list them in alphabetical order. Section 558.515 is amended editorially to display the conditions of use in paragraph (d) in a table 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)(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.
