    Following the withdrawal of approval of these NADAs, Eon Labs 
Manufacturing, Inc., is no longer sponsor of an approved application. 
Therefore, 21 CFR 510.600(c) is amended to remove entries for this 
sponsor.
    As provided below, the animal drug regulations are amended to 
reflect the withdrawal of approvals. The regulations for penicillin G 
procaine

[[Page 18442]]

intramammary dosage forms (21 CFR 526.1696a) are also amended to 
correct several errors and to reflect a current format.
    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.
