Accordingly, the agency is amending the regulations in §§ 520.1840, 558.58, 558.115, 558.128, 558.198, 558.311, 558.355, 558.360, 558.435, 558.450, 558.460, 558.465, 558.485, 558.515, 558.550, 558.555, 558.625, and 558.635 (21 CFR 520.1840, 558.58, 558.115, 558.128, 558.198, 558.311, 558.355, 558.360, 558.435, 558.450, 558.460, 558.465, 558.485, 558.515, 558.550, 558.555, 558.625, and 558.635) to reflect the transfer of ownership. In addition, §§ 520.1840 and 558.485 are being revised to reflect current format.
Section 558.450 is also being amended to remove the entries for combination uses of oxytetracycline (OTC) with monensin, provided under NADA 99-066, because they are redundant with entries in § 558.355. The entry for the use of 400 grams per (g/) ton OTC with 90 to 110 g/ton monensin in § 558.450(d)(1)(vi) is an error created during prior revisions (61 FR 51588, Oct. 3, 1996). The correct drug levels, 200 g/ton OTC with 90 to 110 g/ton monensin, for the same indications are codified in § 558.355(f)(1)(viii). The entry for the use of 500 g/ton OTC with 90 to 110 g/ton monensin in § 558.450(d)(1)(vii) is redundant with § 558.355(f)(1)(xxii).
This rule 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.
