The supplemental NADA provides for the use of lincomycin in swine feed for the control of porcine proliferative enteropathies (ileitis).

DATES: This rule is effective May 24, 2002.

FOR FURTHER INFORMATION CONTACT: Steven D. Vaughn, Center for Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-827-7584, e-mail: svaughn@cvm.fda.gov.

SUPPLEMENTARY INFORMATION: Pharmacia & Upjohn Co., 7000 Portage Rd., Kalamazoo, MI 49001-0199, fileda supplement to NADA 97-505 that provides for use of LINCOMIX 20 (lincomycin hydrochloride) and LINCOMIX 50 Feed Medications in medicated swine feeds for the control of porcine proliferative enteropathies (ileitis) caused by Lawsonia intracellularis. The supplemental application is approved as of February 28, 2002, and the regulations are amended in 21 CFR 558.325 to reflect the approval. Section 558.325 is also being revised to reflect a current 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.

Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this approval qualifies for 3 years of marketing exclusivity beginning February 28, 2002, because the application contains substantial evidence of the effectiveness of the drug involved, any studies of animal safety

[[Page 36513]]

or, in the case of food-producing animals, human food safety studies (other than bioequivalence or residue studies) required for approval of the application and conducted or sponsored by the applicant.

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.
