The agency is amending parts 510 and 520 (21 CFR parts 510 and 520) to reflect the change of sponsor. The agency is amending § 510.600(c)(1) and (c)(2) to remove the sponsor name for I. D. Russell Co., Laboratories because the firm no longer is the holder of any approved NADA's.
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 congressional review requirements in 5 U.S.C 801-808.
