Animal and Plant Health Inspection Service March 7, 2006 – Federal Register Recent Federal Regulation Documents

We are advising the public that an environmental assessment has been prepared for a proposed field trial using two transgenic grass lines. The trial consists of Argentine bahiagrass plants that are genetically engineered to express resistance to the herbicide glufosinate and resistance to the antibiotic kanamycin. Each of 4 sets of 12 genetically engineered bahiagrass plants will be encircled with a ring of several untransformed cultivars of bahiagrass. The purpose of the field trial is to study the likelihood of hybrid formation as a result of pollen movement from the transgenic plants to the nontransgenic plants. Data gained from this field experiment will also be used to evaluate current confinement practices for this species of transgenic grass. The environmental assessment is available to the public for review and comment.

We are adopting as a final rule, without change, an interim rule that amended the Karnal bunt regulations by adding certain areas in Maricopa and Pinal Counties, AZ, to the list of regulated areas and by removing certain areas or fields in Maricopa County, AZ, from the list of regulated areas. Those actions were necessary to prevent the spread of Karnal bunt into noninfected areas of the United States and to relieve restrictions on certain areas that were no longer necessary.
