II. Change of Sponsor's Address
Alexion Pharmaceuticals, Inc., 100 College St., New Haven, CT 06510
has informed FDA that it has changed its address to 121 Seaport Blvd.,
Boston, MA 02210.
Purina Animal Nutrition LLC, 1080 County Road F West, Shoreview, MN
55126-2910 has informed FDA that it has changed its address to 4001
Lexington Ave., North Arden Hills, MN 55126-2910.
III. Technical Amendments
FDA is making the following amendment to improve the accuracy of
the animal drug regulations:
<bullet> 21 CFR 520.304 is amended to reflect the currently
approved strengths of carprofen chewable tablets.
<bullet> 21 CFR part 522 is amended to organize sections for
injectable pentobarbital drugs by their titles in alphabetic sequence.
<bullet> 21 CFR 558.128 is amended to add introductory text
identifying the paragraph for medicated cattle feeds containing
chlortetracycline.
<bullet> 21 CFR 558.355 is amended to add introductory text
identifying the paragraph for medicated cattle feeds containing
monensin.
IV. 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
[[Page 61684]]
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.''

the industry standard of 79.5 brix.
