II. Withdrawal of Approval

    Elanco US Inc., 2500 Innovation Way, Greenfield, IN 46140, has 
requested that FDA withdraw approval of NADA 093-329 for use of a 
sustained-release bolus containing sulfamethazine in cattle because the 
product is no longer manufactured or marketed. As provided in the 
regulatory text of this document, the animal drug regulations are 
amended to reflect this action. Elsewhere in this issue of the Federal 
Register, FDA gave notice that approval of NADA 093-329, and all 
supplements and amendments thereto, is withdrawn.

III. Change of Sponsor

    VetDC, Inc., 320 E Vine Dr., Suite 218, Fort Collins, CO 80524, has

interest in, newly approved NADA 141-545 for TANOVEA (rabacfosadine) 
for Injection to Elanco US Inc., 2500 Innovation Way, Greenfield, IN

27, 1975).
     21 CFR 529.1940 is amended to add limitations to the use

V. Incorporation by Reference

    FDA is incorporating by reference an analytical method approved by 
the Office of the Federal Register in accordance with 5 U.S.C. 552(a) 
and 1 CFR part 51. To obtain a copy of the analytical method, go to: 
https://www.fda.gov/about-fda/center-veterinary-medicine/cvm-foia-electronic-reading-room. You may inspect a copy at the office of the 
Dockets Management Staff (HFA-305), Food and Drug Administration, 5630 
Fishers Lane, Rm. 1061, Rockville, MD 20852, 240-402-7500, between 9 
a.m. and 4 p.m., Monday through Friday.
    This standard adds a method of detection for total for residues of 
the carcinogenic excipient n-methyl-2-pyrrolidone in uncooked edible 
swine tissues to a section established for a method for residues of n-
methyl-2-pyrrolidone in uncooked edible cattle tissues.

VI. 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.''
