application (NADA) filed by Bayer HealthCare LLC. The supplemental NADA 
provides for the addition of a pathogen to the indications for use of

FOR FURTHER INFORMATION CONTACT: Cindy L. Burnsteel, Center for 
Veterinary Medicine (HFV-130), Food and Drug Administration, 7500

SUPPLEMENTARY INFORMATION: Bayer HealthCare LLC, Animal Health 
Division, P.O. Box 390, Shawnee Mission, KS 66201, filed a supplement 
to NADA 141-068 for BAYTRIL 100 (enrofloxacin), an injectable solution. 
The supplemental NADA provides for the addition of Mycoplasma bovis to 
the pathogens in the indication for use of enrofloxacin solution in 
cattle, as a single injection, for the treatment of bovine respiratory 
disease (BRD). The supplemental NADA is approved as of March 10, 2011, 
and the regulation in 21 CFR 522.812 is amended to reflect the 
approval.
    In accordance with the freedom of information provisions of 21 CFR 
part 20 and Sec.  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.
    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 supplemental approval 
qualifies for 3

years of marketing exclusivity beginning on the date of approval.
    The Agency has determined under 21 CFR 25.33 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.
