Phoenix Scientific, Inc., 3915 South 48th St. Terrace, P.O. Box 6457, St. Joseph, MO 64506-0457, filed ANADA 200-069 that provides for veterinary prescription use of FERTELIN (gonadorelin diacetate tetrahydrate) Injection by intramuscular or intravenous injection in dairy cattle for the treatment of ovarian cysts. Phoenix's FERTELIN Injection is approved as a generic copy of Merial, Ltd.'s CYSTORELIN, approved under NADA 98-379. ANADA 200-069 is approved as of August 26, 2002, and the regulations are amended in § 522.1078 (21 CFR 522.1078) to reflect the approval. Section 522.1078 is also being revised to reflect 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 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)(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.
