State University of New York College of Environmental Science and Forestry; Availability of a Revised Petition, Draft Environmental Impact Statement, and Draft Plant Pest Risk Assessment for Determination of Nonregulated Status for Blight-Tolerant Darling 54 American Chestnut (Castanea dentata) Developed Using Genetic Engineering

Animal and Plant Health Inspection Service, USDA.

We will consider all comments that we receive on or before July 21, 2025.

We are advising the public that the Animal and Plant Health Inspection Service has prepared a revised draft environmental impact statement (EIS) and revised draft plant pest risk assessment (PPRA) evaluating the potential environmental impacts and plant pest risk that may result from the approval of a petition for nonregulated status for blight-tolerant American chestnut ( Castanea dentata) from the State University of New York College of Environmental Science and Forestry. The trees have been developed using genetic engineering to express an oxalate oxidase enzyme from wheat as a defense against the fungal pathogen Cryphonectria parasitica, making American chestnut tolerant to chestnut blight. Based on a revised petition submitted by the State University of New York College of Environmental Science and Forestry, we have revised the draft EIS and draft PPRA. We are making the revised petition, revised draft EIS, and revised draft PPRA available for public review and comment.
