----------------------------------------------------------------------------------------------------------------

Following these changes of sponsorship, American Pharmaceuticals and 
Cosmetics, Inc.; Aratana Therapeutics, Inc.; and Dragon Fire Holding 
Co., Inc. are no longer the sponsor of an approved application. 
Accordingly, the regulations in parts 510, 520, 522, and 524 are being 
amended to reflect these changes.

III. Change of Sponsor's Address

    Halocarbon Products Corp., 887 Kinderkamack Rd., River Edge, NJ 
07661 has informed FDA that it has changed its address to 6525 The 
Corners Pkwy., Suite 200, Peachtree Corners, GA 30092. Accordingly, we 
are amending Sec.  510.600(c) to reflect this change.

IV. Withdrawals of Approval

    Fleming Laboratories, Inc., P.O. Box 34384, Charlotte, NC 28234, 
has requested that FDA withdraw approval of NADA 010-005 for use of 
WAZINE (dipiperazine sulfate and piperazine hydrochloride) Soluble 
Powders because the product is no longer manufactured or marketed. 
Following this withdrawal of approval, Fleming Laboratories, 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). In addition, Fleming Laboratories, Inc.'s product was the 
only piperazine product approved for use in food-producing animals. 
Accordingly, tolerances for piperazine will be removed from part 556.
    Also, Halocarbon Products Corp., 6525 The Corners Pkwy., Suite 200, 
Peachtree Corners, GA 30092, has requested that FDA withdraw approval 
of ANADA 200-200 for use of Halothane USP (halothane) because the 
product is no longer manufactured or marketed.
    Lastly, Mylan Institutional LLC, 4901 Hiawatha Dr., Rockford, IL 
61103, has requested that FDA withdraw approval of ANADA 200-472 for 
use of Fomepizole Injection because the product is no longer 
manufactured or marketed.
    Elsewhere in this issue of the Federal Register, FDA gave notice 
that approval of NADA 010-005 and ANADAs 200-200 and 200-472, and all 
supplements and amendments thereto, is withdrawn effective February 3, 
2020. As provided in the regulatory text of this document, the animal 
drug regulations in parts 510, 520, 556, and 529 are amended to reflect 
these actions.

V. Technical Amendments

    FDA is revising the regulations at 21 CFR 520.2520d to reflect the 
approved conditions of use of trichlorfon, phenothiazine, and 
piperazine soluble powder for oral administration to horses as an 
anthelmintic. This information was deleted in error during 
redesignation (79 FR 28833, May 20, 2014). FDA is also revising the 
regulations at 21 CFR 520.2612 to reflect the currently approved dosage 
for trimethoprim and sulfadiazine

[[Page 4207]]

suspension for oral administration to horses as an antimicrobial. 
Lastly, FDA is revising the assay limits for nicarbazin medicated feeds 
at 21 CFR 558.4(d) in the ``Category II'' table. These actions are 
being taken to improve the accuracy of the regulations.

VI. Legal Authority

    This final rule is issued under section 512(i) of the Federal Food, 
Drug, and Cosmetic Act (the 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.''

Reporting and recordkeeping requirements.

authority delegated to the Commissioner of Food and Drugs, 21 CFR parts 
510, 520, 522, 524, 529, 556, and 558 are amended as follows:

    (c) Conditions of use--(1) Indications and amount. (i) Freshwater-
reared finfish eggs for the control of mortality in due to 
saprolegniasis associated with fungi in the family Saprolegniaceae:
    (A) For all coldwater and coolwater species of freshwater-reared 
finfish eggs: 500 to 1,000 mg per liter (/L) of culture water for 15 
minutes in a continuous flow system once per day on consecutive or 
alternate days until hatch, or
    (B) For all freshwater-reared warmwater finfish eggs: 750 to 1,000 
mg/L for 15 minutes in a continuous flow system once per day on 
consecutive or alternate days until hatch.
    (ii) Freshwater-reared finfish for the control of mortality due to 
saprolegniasis associated with the fungi in the family Saprolegniaceae: 
For freshwater-reared coldwater finfish including salmonids (all life 
stages), freshwater-reared coolwater finfish fingerlings and adults, 
and freshwater-reared warmwater finfish fingerlings and adults: 75 mg/L 
for 60 minutes in continuous flow water supply or as a static bath once 
per day on alternate days for three treatments.
    (iii) Freshwater-reared salmonids for the control of mortality due 
to bacterial gill disease associated with Flavobacterium 
branchiophilum: 100 mg/L for 30 minutes, or 50 to 100 mg/L for 60 
minutes, in a continuous flow water supply or as a static bath once per 
day on alternate days for three treatments.
    (iv) Freshwater-reared salmonids for the treatment and control of 
Gyrodactylus spp: 100 mg/L for 30 minutes, or 50 to 100 mg/L for 60 
minutes, in a continuous flow water supply or as a static bath once per 
day on alternate days for three treatments.
    (v) Freshwater-reared coolwater and warmwater finfish fingerlings 
and adults for the control of mortality due to external columnaris 
disease associated with Flavobacterium columnare: 50 to 75 mg/L for 60 
minutes in continuous flow water supply or as a static bath once per 
day on alternate days for three treatments.
    (vi) Freshwater-reared coolwater finfish fry and warmwater finfish 
fry for the control of mortality due to external columnaris disease 
associated with Flavobacterium columnare: 50 mg/L for 60 minutes in 
continuous flow water supply or as a static bath once per day on 
alternate days for three treatments.
    (2) Limitations. (i) Initial bioassay on a small number is 
recommended before treating the entire group.
    (ii) Eggs: Some strains of rainbow trout eggs are sensitive to 
hydrogen peroxide treatment at a time during incubation concurrent with 
blastopore formation through closure, about 70 to 140 Daily Temperature 
Units, [deg]C. Consider withholding treatment or using an alternate 
therapeutant during that sensitive time to reduce egg mortalities due 
to drug toxicity.
    (iii) Finfish: Because finfish sensitivity to 35% PEROX-AID[supreg] 
increases with increasing water temperature, consider administering 
initial treatments at the lower end of the treatment regimen or 
reducing water temperature before treatment. Do not use this product to 
treat northern pike (Esox lucius) or paddlefish (Polyodon spathula) of 
any age. Do not use this product to treat pallid sturgeon fry. Use with 
caution on walleye (Sander vitreus) and ornamental finfish.
    (iv) Preharvest withdrawal time: Zero days.
