End Further Info End Preamble Start Supplemental Information


ADM Alliance Nutrition, Inc., 1000 North 30th St., Quincy, IL 62305-3115, filed a supplement to NADA 48-480 that provides for the use of CHLORATET 50 (chlortetracycline), a Type A medicated article containing 50 grams of chlortetracycline per pound, for the manufacture of medicated feeds for livestock and poultry. The supplement provides for use of Type A medicated articles containing 90 or 100 grams of chlortetracycline per pound. The supplemental NADA is approved as of January 7, 2010, and the regulations are amended in 21 CFR 558.128 to reflect the approval.

Approval of this supplemental NADA did not require review of additional safety or effectiveness data or information. Therefore, a freedom of information summary is not required.

FDA has determined under 21 CFR 25.33 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.
