III. Withdrawals of Approval

    Elanco US Inc., 2500 Innovation Way, Greenfield, IN 46140, has 
requested that FDA withdraw approval of NADA 140-939 for use of 
RUMENSIN (monensin) and TYLAN (tylosin phosphate) Type A medicated 
articles in the manufacture of combination drug Type C medicated cattle 
feeds because the product is no longer manufactured or marketed.
    Also, Sergeant's Pet Care Products, Inc., 10077 S 134th St., Omaha, 
NE 68138 has requested that FDA withdraw approval of ANADA 200-600 for 
WORMX (pyrantel pamoate) Flavored Tablets because the product is no 
longer manufactured or marketed.
    Elsewhere in this issue of the Federal Register, FDA gave notice 
that approval of NADA 140-939 and ANADA 200-600, and all supplements 
and amendments thereto, is withdrawn, effective March 25, 2019. As 
provided in the regulatory text of this document, the animal drug 
regulations are amended to reflect these actions.

IV. Technical Amendments

    In addition, we are reformatting the regulations to present the 
approved conditions of use of halofuginone, monensin, and salinomycin 
in tabular format in the respective named sections of 21 CFR part 558. 
This action is being taken to improve the readability of the 
regulations.

V. 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) because it 
is a ``rule of particular applicability'' under 5 U.S.C. 804(3)(A). 
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.''
