    Accordingly, the animal drug regulations are being amended to 
reflect these changes of sponsorship. Following this withdrawal of 
approval, Nexcyon Pharmaceuticals, Inc. is no longer the sponsor of an 
approved application. Accordingly, it will be removed from the list of 
sponsors of approved applications in Sec.  510.600(c).

III. Withdrawals of Approval

    In addition, during January and February 2017, the following 
sponsor requested that FDA withdraw approval of the NADAs listed in the 
following table because the products are no longer manufactured or 
marketed:

                       IA 51250.        Injection.
------------------------------------------------------------------------

    Elsewhere in this issue of the Federal Register, FDA gave notice 
that approval of NADA 009-505, and all supplements and amendments 
thereto, is withdrawn, effective May 22, 2017. Following this 
withdrawal of approval, Sioux Biochemical, Inc., is no longer the 
sponsor of an approved application. As provided in the regulatory text 
of this document, the animal drug regulations are amended to reflect 
this voluntary withdrawal of approval.

IV. Technical Amendments

    We are also making several technical amendments in part 558, which 
was amended on December 27, 2016 (81 FR 94991), and February 24, 2017 
(82 FR 11510), as part of the FDA Center for Veterinary Medicine's 
(CVM's) Judicious Use Initiative. These actions are being taken to 
improve the accuracy of the regulations.
    This final rule is issued under Section 512(i) of the Federal Food, 
Drug, and Cosmetic 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 Federal Food, Drug, and 
Cosmetic 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.'' As such, this 
document is also not subject to Executive Order 12866.
