SUPPLEMENTARY INFORMATION:

Pharmacia & Upjohn Co., a Division of Pfizer, Inc., 235 East 42d St., New York, NY 10017, filed supplements to NADA 140-338 for NAXCEL (ceftiofur sodium) Sterile Powder for Injection and to NADA 140-890 for EXCENEL RTU (ceftiofur hydrochloride) Sterile Suspension. These products are approved for veterinary prescription use in livestock by injection for the treatment or control of various bacterial diseases. Pharmacia & Upjohn Co. also filed supplements to NADA 141-238 for SPECTRAMAST LC (ceftiofur hydrochloride) Sterile Suspension and to NADA 141-239 for SPECTRAMAST DC (ceftiofur hydrochloride) Sterile Suspension. These products are approved for veterinary prescription use by intramammary infusion in dairy cows for the treatment of bacterial mastitis. The supplemental NADAs establish or revise preslaughter withdrawal periods in cattle consistent with the tolerance for residues of ceftiofur in bovine kidney which was revised elsewhere in this issue of the Federal Register. The applications are approved as of June 2, 2006, and the regulations are amended in 21 CFR 522.313 and 526.314 to reflect the approval. The basis of approval is discussed in the freedom of information summaries.

In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), summaries of the safety and effectiveness data and information submitted to support approval of these applications 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) that these actions are of a type that do 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.
