    Following these changes of sponsorship, Ark Sciences, Inc. and 
Vetcare Oy are no longer the sponsor of an approved application. 
Accordingly, the drug labeler codes for these firms will be removed 
from Sec.  510.600 (21 CFR 510.600).

III. Change of Sponsor Address

    Anivive Lifesciences, Inc., 3250 Airflite Way, Suite 400, Long 
Beach, CA 90807 has informed FDA that it has changed its address to 
3777 Worsham Ave. Long Beach, CA 90808. As provided in the regulatory 
text, Sec.  510.600 is amended to reflect this change.

IV. Technical Amendments

    FDA is making the following amendments to improve the accuracy of 
the animal drug regulations:
     21 CFR 510.600 is amended to remove Ark Sciences, Inc., 
and Vetcare Oy from the list of sponsors of approved applications and 
to revise the address for Anivive Lifesciences, Inc. A punctuation 
change is made in the codified name for Ve[aacute]toquinol USA, Inc.
     21 CFR 520.563 is amended to reflect the correct section 
title for diatrizoate oral solution.
     21 CFR 520.2640 is amended to reflect sponsors' container 
contents and the dosage in parts per million of tylosin tartrate 
soluble powder for use in drinking water of turkeys and swine.
     21 CFR 522.955 is amended to reflect drug labeler codes of 
application sponsors and to revise a pathogen name for florfenicol 
injectable solution in cattle.
     21 CFR 522.2471 is amended to reflect a revised withdrawal 
period and human food safety warnings for tilmicosin injectable 
solution in sheep.
     The heading for Part 528 is revised to reflect a more 
accurate title.
     21 CFR 558.95 is amended to reflect revised classes of 
cattle for use of bambermycins medicated feeds.
     21 CFR 558.128 is amended to reflect approved 
incorporation rates for

[[Page 76420]]

chlortetracycline medicated feeds for cattle.
     21 CFR 558.342 is amended to reflect all sponsors of 
approved applications for use of melengestrol medicated feeds in 
heifers.
     21 CFR 558.450 is amended to reflect revised residue 
warnings for use of oxytetracycline medicated feeds in cattle.
     21 CFR 558.455 is amended to reflect a revised indication 
for use of oxytetracycline with neomycin in medicated cattle feeds and 
an updated format.
     21 CFR 558.575 is amended to reflect approved 
incorporations rates for use of sulfadimethoxine and ormetoprim in 
medicated feeds for salmonids and catfish.

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)(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.''

List of Subjects

Reporting and recordkeeping requirements.
