[[Page 18117]]

    Elsewhere in this issue of the Federal Register, FDA gave notice 
that approval of NADAs 055-036, 055-050, 055-056, 055-061, 055-068, 
065-013, 065-493, and 065-500, and all supplements and amendments 
thereto, is withdrawn, effective March 30, 2020. As provided in the 
regulatory text of this document, the animal drug regulations are 
amended to reflect these actions.

III. Changes of Sponsor

    Cooperative Research Farms, Box 69, Charlotteville, NY 12036, has 
informed FDA that it has transferred ownership of, and all rights and 
interest in, approved NADA 119-253 for Cattle Block M (monensin) a 
free-choice Type C medicated cattle feed to Wildcat Feeds, 215 NE 
Strait Ave., Topeka, KS 66616. Following this change of sponsorship, 
Cooperative Research Farms is no longer the sponsor of an approved 
application.
    Dechra, Ltd., Snaygill Industrial Estate, Keighley Rd., Skipton, 
North Yorkshire, BD23 2RW, United Kingdom, has informed FDA that it has 
transferred ownership of, and all rights and interest in, approved 
ANADA 200-273 for VETRO-GEN Veterinary Ophthalmic Ointment to Putney, 
Inc., One Monument Sq., suite 400, Portland, ME 04101.
    Huvepharma EOOD, 5th Floor, 3A Nikolay Haytov Str., 1113 Sofia, 
Bulgaria, has informed FDA that it has transferred ownership of, and 
all rights and interest in, approved NADA 141-472 for virginiamycin and 
diclazuril Type C medicated feed to Elanco US Inc., 2500 Innovation 
Way, Greenfield, IN 46140.
    Accordingly, we are amending the regulations to reflect these 
changes.

IV. Change of Sponsors' Name and Addresses

    Putney, Inc., One Monument Sq., suite 400, Portland, ME 04101, has 
informed FDA that it has changed its name and address to Dechra 
Veterinary Products LLC, 7015 College Blvd., suite 525, Overland Park, 
KS 66211. In addition, Virbac AH, Inc., 3200 Meacham Blvd., Ft. Worth, 
TX 76137 has informed FDA that it has changed its address to PO Box 
162059, Fort Worth, TX 76161. Accordingly, we are amending Sec.  
510.600(c) (21 CFR 510.600(c)) to reflect these changes.

V. Technical Amendments

    FDA is making the following amendments to improve the readability 
and accuracy of the animal drug regulations:
     The contact information in 21 CFR 500.1410, which provides 
for the incorporation by reference of the residue assay method for n-
methyl-2-pyrrolidone, is being updated.
     We are removing entries for ``Strategic Veterinary 
Pharmaceuticals, Inc.'' from the lists of sponsors of approved 
applications in Sec.  510.600(c) and the drug labeler code for KC 
Pharmacal from 21 CFR 520.260.
     The indications for use of oxytetracycline soluble powder 
in honey bees at 21 CFR 520.1660d are amended to reflect current 
labeling.
     The single section for euthanasia injectable solutions at 
21 CFR 522.900 is being removed and separate sections for the active 
pharmaceutical ingredients are added at 21 CFR 522.1697 and 522.2092.
     The section heading in 21 CFR 524.1742 for ``N-
(Mercaptomethyl) phthalimide S-(O,O-dimethyl phosphorodithioate) 
emulsifiable liquid'' is amended to read ``Phosmet emulsifiable 
liquid''.
     The entries in 21 CFR parts 556 and 558 for coumaphos for 
which approval of the last approved application was withdrawn in 2018 
(83 FR 48940, September 28, 2018) are being removed.
     The entries in part 556 (21 CFR part 556) are being 
removed for tolerances of residues of erythromycin in swine tissues, of 
virginiamycin in turkey tissues, and of new animal drugs for which 
approval of their applications has been withdrawn.
     Cross-references to related approved uses of new animal 
drugs in part 556 and to related tolerances for drugs approved for use 
in food-producing animals in 21 CFR parts 520, 522, 524, and 558 are 
being corrected.
     A redundant cross-reference for related tolerances in 21 
CFR 558.355 for use of monensin in medicated feeds is being removed and 
reserved.
     The acceptable daily intake of total residues of 
ivermectin and tolerances for residues of ivermectin in cattle liver 
and muscle in Sec.  556.344 are being corrected.
     The acceptable daily intake of total residues of 
tildipirosin in Sec.  556.733 is being corrected.
     The regulations in 21 CFR 520.2260b for sulfamethazine 
sustained-release boluses and in 21 CFR 522.1662a for oxytetracycline 
hydrochloride injection are being reformatted to present the tolerance 
cross-reference in a consistent location.
     Typographical errors are being corrected wherever they 
have been found.

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.''
