SUPPLEMENTARY INFORMATION: Roussel-UCLAF, Division Agro-Veterinaire, 
163 Ave. Gambetta, 75020 Paris, France, filed supplemental NADA 140-
897, which provides for use of an ear implant containing 2 pellets, 
each pellet containing 20 milligrams (mg) of trenbolone acetate and 4 
mg of estradiol. The implant is used in pasture steers (slaughter, 
stocker, feeder) for increased rate of weight gain. The supplemental 
NADA is approved as of March 27, 1996, and the regulations are amended 
in 21 CFR 522.2477 by adding new paragraph (c)(3) to reflect the 
approval. The basis for approval is discussed in the freedom of 
information summary.
    In accordance with the freedom of information provisions of part 20 
(21 CFR part 20) and Sec. 514.11(e)(2)(ii) (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, 12420 
Parklawn Dr., rm. 1-23, Rockville, MD 20857, between 9 a.m. and 4 p.m., 
Monday through Friday.
    Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this approval qualifies 
for a 3-year period of marketing exclusivity beginning on March 27, 
1996, because new clinical or field investigations (other than 
bioequivalence or residue studies) essential to the approval were 
conducted or sponsored by the applicant.
    The agency has carefully considered the potential environmental 
effects of this action. FDA has concluded that the action will not have 
a significant impact on the human environment, and that an 
environmental impact statement is not required. The agency's finding of 
no significant impact and the evidence supporting that finding, 
contained in an environmental assessment, may be seen in the Dockets 
Management Branch (address above) between 9 a.m. and 4 p.m., Monday 
through Friday.
