SUPPLEMENTARY INFORMATION:

FDA is amending the animal drug regulations to reflect approval actions for NADAs and ANADAs during September 2013, as listed in table 1. In addition, FDA is informing the public of the availability, where applicable, of documentation of environmental review required under the National Environmental Policy Act (NEPA) and, for actions requiring review of safety or effectiveness data, summaries of the basis of approval (FOI Summaries) under the Freedom of Information Act (FOIA). These public documents 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. Persons with access to the Internet may obtain these documents at the Center for Veterinary Medicine FOIA Electronic Reading Room: http://www.fda.gov/​AboutFDA/​CentersOffices/​OfficeofFoods/​CVM/​CVMFOIAElectronicReadingRoom/​default.htm.

In addition, Piedmont Animal Health, 204 Muirs Chapel Rd., suite 200, Greensboro, NC 27410 has informed FDA that it has transferred ownership of, and all rights and interest in, ANADA 200-555 for LIBREVIA (carprofen) Soft Chewable Tablets to Bayer HealthCare LLC, Animal Health Division, P.O. Box 390, Shawnee Mission, KS 66201. Accordingly, the Agency is amending the regulations to reflect this change of sponsorship.

Following this change of sponsorship, Piedmont Animal Health is no longer a sponsor of an approved NADA. Accordingly, FDA is amending 21 CFR 510.600 to remove the entries for this firm.

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.Start Printed Page 66264
