The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is deregulating Pioneer Hi-Bred International, Inc.’s (Pioneer) DP23211 corn. This corn was developed using genetic engineering to resist corn rootworm and tolerate glufosinate herbicides. After a thorough review, we concluded that DP23211 corn is unlikely to pose a plant pest risk. 

Our determination is based on our evaluation of the following:

• Information Pioneer submitted in its petition for deregulation
• Our analyses
• Public comments received in response to previous notices announcing the availability of the petition, draft environmental assessment (EA) and draft plant pest risk assessment (PPRA) 

We are publishing the Determination of Nonregulated Status, final EA, final PPRA, and response to public comments. These documents support APHIS’ review and analysis of any potential environmental impacts associated with deregulating DP23211 corn.
