SUPPLEMENTARY INFORMATION:

Pharmacia and Upjohn Co., 7000 Portage Rd., Kalamazoo, MI 49001-0199, filed a supplement to NADA 111-636 that provides for use of LINCOMIX (lincomycin hydrochloride) Soluble Powder for making medicated drinking water for the management of various bacterial diseases of swine and chickens. The supplemental NADA provides for replacement of the limitation “Not for use in swine weighing more than 250 pounds” with “The safety of lincomycin has not been demonstrated for pregnant swine or swine intended for breeding.” The supplemental application is approved as of December 31, 2001, and the regulations are amended in 21 CFR 520.1263c to reflect the approval. Section 520.1263c is also being revised to reflect current editorial format.

In accordance with the freedom of information provisions of 21 CFR part 20 and 514.11(e)(2)(ii), a summary of safety and effectiveness data and information submitted to support approval of this supplemental application may be seen in the Dockets Management Branch (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday.

The agency has determined under 21 CFR 25.33(a)(1) that this action is of a type that does not individually or cumulatively have a significant effect on the human environment. Therefore, neither an environmental assessment nor an environmental impact statement is required.

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.
