EPA Exempts Bt Vip3Aa Protein from Tolerance Requirement

August 8, 2008

The U.S. Environmental Protection Agency (EPA) has announced the exemption of the Bacillus thuringiensis (Bt) Vip3Aa proteins from the tolerance requirement for transgenic protein residues. Under the regulation, there will be no more need to establish a maximum permissible level of the BT protein when used as a plant incorporated protectant in corn and cotton. Based on rigorous scientific tests, EPA concluded that the Bt proteins are unlikely to endanger human and animal health or the environment.

The regulation is effective August 6, 2008. Objections and requests for hearings must be received on or before October 6, 2008. For more information, read http://edocket.access.gpo.gov/2008/pdf/E8-17931.pdf
