FDA has found that § 520.1263c (21 CFR 520.1263c) does not reflect the approved preslaughter withdrawal time for three lincomycin soluble powder products used to make medicated drinking water for swine. The 6-day withdrawal time was inadvertently removed for a generic product approved under ANADA 200-189 at the time it was being removed for the pioneer product approved under NADA 111-636 (64 FR 13341, March 18, 1999). The conditions of use for two other products approved February 4, 1999, under ANADA 200-241 (64 FR 13508, March 19, 1999) and September 22, 1999, under ANADA 200-233 (64 FR 66382, November 26, 1999) were subsequently codified without a withdrawal period. At this time, the regulations are being amended in § 520.1263c to correct these errors.

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.
