--------------------------------------------------------------------------------------------------------------------------------------------------------
\1\ The Agency has carefully considered an environmental assessment (EA) of the potential environmental impact of this action and has made a finding of
  no significant impact (FONSI).

II. Technical Amendments

    With the approval of NADA 141-481, Kindred Biosciences, Inc. is now 
the sponsor of an approved application. Accordingly, we are amending 
Sec.  510.600(c) to add the name, address, and drug labeler code of 
this sponsor.
    Piramal Healthcare Ltd., Piramal Tower, Ganpatrao Kadam Marg, Lower 
Parel, Mumbai-400 013, India, has informed FDA that it has changed its 
name and address to Piramal Enterprises Ltd., Ananta, Agastya Corporate 
Park, Opp Fire Brigade, Kamani Junction, LBS Mag Kurla (West), Mumbai, 
400070, India. We are amending Sec.  510.600(c) to reflect this change.
    We are also making technical amendments to update the scientific 
name of a pathogenic bacterium and to accurately list the 
concentrations of active ingredients in an otic dosage form new animal 
drug. We are also making a technical amendment to correct the sponsor 
of epsiprantel tablets. These actions are being taken to improve the 
accuracy of the regulations.
    In addition, we are reformatting the regulations to create a 
tabular display of

[[Page 64739]]

the approved uses of narasin and a separate section for uses of a 
fixed-ratio, combination drug Type A medicated article containing 
narasin and nicarbazin. These actions are being taken to improve the 
readability, consistency, and accuracy of the regulations.

III. Legal Authority

    This final rule is issued under section 512(i) of the Federal Food, 
Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 360b(i)), which requires 
Federal Register publication of ``notice[s] . . . effective as a 
regulation,'' of the conditions of use of approved new animal drugs. 
This rule sets forth technical amendments to the regulations to codify 
recent actions on approved new animal drug applications and corrections 
to improve the accuracy of the regulations, and as such does not impose 
any burden on regulated entities.
    Although denominated a rule pursuant to the FD&C Act, this document 
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. 
Likewise, this is not a rule subject to Executive Order 12866, which 
defines a rule as ``an agency statement of general applicability and 
future effect, which the agency intends to have the force and effect of 
law, that is designed to implement, interpret, or prescribe law or 
policy or to describe the procedure or practice requirements of an 
agency.''
