Dicamba GE Crops Environmental Impact Statement and Related Documents

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) announced determinations of nonregulated status for Monsanto Company’s (Monsanto) soybeans and cotton that are resistant to certain herbicides, including one known as dicamba. This notice also includes the availability of our written determinations and Record of Decision (ROD).

Notice of these determinations was published in the Federal Register on January, 20, 2015, which was also the effective date for these deregulations.  A copy of the notice, Monsanto petitions, determinations, ROD, and supporting documents can be found below.

EPA is nearing completion of its concurrent review of the new use of the related herbicides on these GE plants. It is expected that EPA will make its proposed regulatory decision in the coming months.

Monsanto's Dicamba-Tolerant Crops Draft EIS Virtual Public Comment Meeting

On August 11, 2014, USDA made available for public review and comment a Draft Environmental Impact Statement (DEIS) as part of its review to determine whether to deregulate genetically engineered (GE) cotton resistant to the herbicides glufosinate and dicamba, and soybean resistant to dicamba. The DEIS analyzes the potential environmental impacts of these GE cotton and soybean varieties developed by Monsanto Company (Monsanto).

APHIS held a virtual public meeting on Thursday, September 11, 2014, to receive comments on the DEIS . We will consider all public comments made during the virtual meeting as well as those submitted to the docket (APHIS-2013-0043) on before finalizing the DEIS and preliminary plant pest risk assessment, and making our final regulatory decision on the Monsanto petitions.

Monsanto's Dicamba-Tolerant Crops EIS Virtual Public Comment Scoping Meeting

On May 16, 2013, APHIS' Biotechnology Regulatory Services (BRS) published notices of intent (NOI) in the Federal Register to prepare environmental impact statements (EIS), in response to petitions seeking determinations of nonregulated status for Dow's 2,4-D-resistant crops, and Monsanto's dicamba-resistant crops. On June 26 and 27, 2013, APHIS' BRS hosted two online virtual public meetings soliciting public comment on the scope of these draft EISs being prepared for each company's petitions, respectively. The purpose of the meetings was to further delineate the scope of alternatives and environmental impacts and issues discussed in these EISs.
