SUPPLEMENTARY INFORMATION:

Purina Mills, Inc., P.O. Box 66812, St. Louis, MO 63166-6812, filed a supplement to NADA 141-171 for use of BOVATEC 91 (lasalocid) Type A medicated article to make Purina Sugar Mag Block 1440 BVT Medicated Mineral Block, a free-choice Type C medicated feed used for increased rate of weight gain in pasture cattle (slaughter, stocker, feeder cattle, and dairy and beef replacement heifers). The supplement provides for the use of a lasalocid Type A medicated article containing 20 percent lasalocid activity per pound. The supplemental NADA is approved as of August 18, 2006, and the regulations are amended in § 558.311 (21 CFR 558.311) to reflect the approval. Start Printed Page 56008 The basis of approval is discussed in the freedom of information summary.

In addition, FDA is amending § 558.311 to remove redundant text in an entry for combination use of single-ingredient lasalocid and chlortetracycline in cattle feed which was published in error in the Federal Register of April 27, 2006 (71 FR 24816). This correction is being made to improve the accuracy of the regulations.

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.

The agency has determined under 21 CFR 25.33(a)(6) 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.
