                 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:
                 21 CFR 520.304 is amended to reflect the currently
                approved strengths of carprofen chewable tablets.
                 21 CFR part 522 is amended to organize sections for
                injectable pentobarbital drugs by their titles in alphabetic sequence.
                 21 CFR 558.128 is amended to add introductory text
                identifying the paragraph for medicated cattle feeds containing
                chlortetracycline.
                 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.''
                List of Subjects
                21 CFR Part 510
                 Administrative practice and procedure, Animal drugs, Labeling,
                Reporting and recordkeeping requirements.
                21 CFR Parts 520, 522, and 524

                 Therefore, under the Federal Food, Drug, and Cosmetic Act and under
                authority delegated to the Commissioner of Food and Drugs, 21 CFR parts
                510, 520, 522, 524, 556, and 558 are amended as follows:

                \1\ The content of any added vitamin and trace mineral may be varied;
                 however, they should be comparable to those used by the manufacturer
                 for other free-choice cattle feeds. Formulation modifications require
                 FDA approval prior to marketing. Selenium is not approved for the free-
                 choice formulations described in paragraph (e)(3)(iii) of this
                 section. Free-choice cattle feeds containing selenium must comply with
                 published regulations (see 21 CFR 573.920).
                \2\ The percentage of cane molasses and water in the formulation may be
                 adjusted as needed in order to bring the brix value of the molasses to
                 the industry standard of 79.5 brix.
                 (2) Indications for use. As in paragraph (e)(3)(i) of this section.
                 (3) Limitations. Feed a total of 5 mg of fenbendazole per kg (2.27
                mg/lb) of body weight to cattle over a 3- to 6-day period. Retreatment
                may be needed after 4 to 6 weeks. Cattle must not be slaughtered within
                13 days following last treatment. For dairy cattle the milk discard
                time is zero hours. A withdrawal period has not been established for
                this product in pre-ruminating calves. Do not use in calves to be
                processed for veal.
