Cross Vetpharm Group Ltd., Broomhill Rd., Tallaght, Dublin 24, Ireland, filed ANADA 200-364 that provides for oral use of SPECMED (spectinomycin dihydrochloride pentahydrate) Scour-Chek in pigs under 4 weeks of age for the treatment and control of infectious bacterial enteritis (white scours) associated with Escherichia coli. Cross Vetpharm Group Ltd.'s SPECMED Scour-Chek is approved as a generic copy of Phoenix Scientific, Inc.'s SPECTAM Scour Halt, approved under NADA 033-157. The ANADA is approved as of July 29, 2004, and the regulations are amended by removing 21 CFR 520.2122 and by adding 21 CFR 520.2123c 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 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(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 the congressional review requirements in 5 U.S.C. 801-808.
