SUPPLEMENTARY INFORMATION:

Lloyd, Inc., 604 West Thomas Ave., Shenandoah, IA 51601, filed a supplement to NADA 139-236 that provides for use of CERVIZINE 300 (xylazine hydrochloride) solution in elk and wild deer to produce sedation, accompanied by a shorter period of analgesia. The supplemental NADA is approved as of February 10, 2003, and the regulations are amended in § 522.2662 (21 CFR 522.2662) to reflect the approval. The basis of approval is discussed in the freedom of information summary.

Section 522.2662 is also being amended to revise a codified food safety limitation and to add a food safety cautionary statement regarding the use of xylazine in elk and wild deer (Cervidae). Both statements are currently used in labeling for both pioneer and generic xylazine products. Section 522.2662 is also revised to reflect a current format.

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 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(d)(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.
