SUPPLEMENTARY INFORMATION:

Phoenix Scientific, Inc., 3915 South 48th St. Terrace, St. Joseph, MO 64503, filed ANADA 200-345 for Lincomycin-Spectinomycin (lincomycin hydrochloride monohydrate/spectinomycin dihydrochloride pentahydrate) Water Soluble Powder. The application provides for oral use of lincomycin and spectinomycin soluble powder to make medicated drinking water for administration to chickens up to 7 days of age as an aid in the control of airsacculitis caused by either Mycoplasma synoviae or Mycoplasma gallisepticum susceptible to lincomycin-spectinomycin and complicated chronic respiratory disease (air sac infection) caused by Escherichia coli and M. gallisepticum susceptible to lincomycin-spectinomycin. Phoenix Scientific's Lincomycin-Spectinomycin Water Soluble Powder is approved as a generic copy of Pharmacia & Upjohn's L-S 50 (lincomycin hydrochloride monohydrate/ spectinomycin sulfate tetrahydrate) Water Soluble Powder, approved under NADA 46 109. ANADA 200 345 is approved as of February 5, 2004, and the regulations are amended in part 520 (21 CFR part 520) by removing § 520.1263b and by adding § 520.1265 to reflect the approval and a current format. 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 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.

List of Subjects in 21 CFR Part 520

• Animal drugs

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 520 is amended as follows:
