**SUPPLEMENTARY INFORMATION:**
FDA is amending the animal drug regulations to reflect approval actions for NADAs and ANADAs during July 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 CVM FOIA Electronic Reading Room: *http://www.fda.gov/AboutFDA/CentersOffices/OfficeofFoods/CVM/CVMFOIAElectronicReadingRoom/default.htm.*
In addition, ECO LLC, 344 Nassau St., Princeton, NJ 08540 has informed FDA that it has transferred ownership of, and all rights and interest in, ANADA 200-348 for ECOMECTIN (ivermectin) Topical Solution to SmartVet USA, Inc., 22201 West Innovation Dr., Suite 170A, Olathe, KS 66061-1304. Accordingly, the Agency is amending the regulations to reflect this change of sponsorship.
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.
