The regulations in 7 CFR part 340, “Introduction of Organisms and Products Altered or Produced Through Genetic Engineering Which Are Plant Pests or Which There Is Reason To Believe Are Plant Pests,” regulate, among other things, the introduction (importation, interstate movement, or release into the environment) of organisms and products altered or produced through genetic engineering that are plant pests or that there is reason to believe are plant pests. Such genetically engineered organisms and products are considered “regulated articles.”

The regulations in § 340.6(a) provide that any person may submit a petition to the Animal and Plant Health Inspection Service (APHIS) seeking a determination that an article should not be regulated under 7 CFR part 340. Paragraphs (b) and (c) of § 340.6 describe the form that a petition for a determination of nonregulated status must take and the information that must be included in the petition.

On February 5, 2003, APHIS received two petitions from Mycogen Seeds c/o Dow AgroSciences LLC (Mycogen/Dow) of Indianapolis, IN, requesting determinations of nonregulated status under 7 CFR part 340 for cotton (Gossypium hirsutum L.) designated as Cry1F cotton event 281-24-236 (cotton event Cry1F) (APHIS Petition No. 03-036-01p) and Cry1Ac cotton event 3006-210-23 (cotton event Cry1Ac) (APHIS Petition No. 03-036-02p), which have been genetically engineered for resistance to certain lepidopteran insect pests. The Mycogen/Dow petitions state that the subject cotton events should not be regulated by APHIS because they do not present a plant pest risk.

As described in the petitions, cotton events Cry1F and Cry1Ac have been genetically engineered to express synthetic insecticidal proteins derived from the common soil bacterium Bacillus thuringiensis (Bt). The petitioner states that the Cry1F and Cry1Ac proteins are effective in providing protection from the feeding of lepidopteran insect pests such as tobacco budworm, beet armyworm, soybean looper, and cotton bollworm. The subject cotton events also express the pat gene derived from Streptomyces viridochromogenes, a non-pathogenic bacterium. The pat gene encodes the enzyme phosphinothricin acetyltransferase (PAT), which confers tolerance to glufosinate herbicides and is present in cotton events Cry1F and Cry1Ac as a selectable marker. The subject cotton events were developed through use of the Agrobacterium-mediated transformation method. Start Printed Page 10973Cotton events Cry1F and Cry1Ac were developed primarily so that they could be crossed to produce a cotton line which contains both the insecticidal proteins and thereby to maintain a range of effective control options for lepidopteran insect pests and to reduce the potential for the development of resistance to Bt insecticides.

Cotton events Cry1F and Cry1Ac have been considered regulated articles under the regulations in 7 CFR part 340 because they contain gene sequences from the plant pathogen Agrobacterium tumefaciens. These cotton events have been field tested since 1999 in the United States under APHIS notifications. In the process of reviewing the notifications for field trials of the subject cotton, APHIS determined that the vectors and other elements were disarmed and that the trials, which were conducted under conditions of reproductive and physical confinement or isolation, would not present a risk of plant pest introduction or dissemination.

In § 403 of the Plant Protection Act (7 U.S.C. 7701-7772), plant pest is defined as any living stage of any of the following that can directly or indirectly injure, cause damage to, or cause disease in any plant or plant product: A protozoan, a nonhuman animal, a parasitic plant, a bacterium, a fungus, a virus or viroid, an infectious agent or other pathogen, or any article similar to or allied with any of the foregoing. APHIS views this definition very broadly. The definition covers direct or indirect injury, disease, or damage not just to agricultural crops, but also to plants in general, for example, native species, as well as to organisms that may be beneficial to plants, for example, honeybees, rhizobia, etc.

The U.S. Environmental Protection Agency (EPA) is responsible for the regulation of pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended (7 U.S.C. 136 et seq.). FIFRA requires that all pesticides, including herbicides, be registered prior to distribution or sale, unless exempt by EPA regulation. In cases in which genetically modified plants allow for a new use of a pesticide or involve a different use pattern for the pesticide, EPA must approve the new or different use. Accordingly, Mycogen/Dow has submitted a request to EPA for registration of the stacked Cry1F and Cry1Ac protein construct as a plant-incorporated protectant in cotton.

When the use of the pesticide on the genetically modified plant would result in an increase in the residues in a food or feed crop for which the pesticide is currently registered, or in new residues in a crop for which the pesticide is not currently registered, establishment of a new tolerance or a revision of the existing tolerance would be required. Residue tolerances for pesticides are established by EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended (21 U.S.C. 301 et seq.), and the Food and Drug Administration (FDA) enforces tolerances set by EPA under the FFDCA. Mycogen/Dow has submitted a request to EPA for a tolerance exemption for both the Cry1F and Cry1Ac proteins as expressed in the subject cotton events.

FDA published a statement of policy on foods derived from new plant varieties in the Federal Register on May 29, 1992 (57 FR 22984-23005). The FDA statement of policy includes a discussion of FDA's authority for ensuring food safety under the FFDCA, and provides guidance to industry on the scientific considerations associated with the development of foods derived from new plant varieties, including those plants developed through the techniques of genetic engineering. Mycogen/Dow has begun consultation with FDA on the subject cotton events.

To provide the public with documentation of APHIS's review and analysis of the environmental impacts and plant pest risk associated with proposed determinations of nonregulated status for Mycogen/Dow's cotton events Cry1F and Cry1Ac, an environmental assessment has been prepared. The EA was prepared in accordance with (1) The National Environmental Policy Act of 1969 (NEPA), as amended (42 U.S.C. 4321 et seq.), (2) regulations of the Council on Environmental Quality for implementing the procedural provisions of NEPA (40 CFR parts 1500-1508), (3) USDA regulations implementing NEPA (7 CFR part 1b), and (4) APHIS's NEPA Implementing Procedures (7 CFR part 372).

In accordance with § 340.6(d) of the regulations, we are publishing this notice to inform the public that APHIS will accept written comments regarding the petitions for determinations of nonregulated status from interested persons for a period of 60 days from the date of this notice. We are also soliciting written comments from interested persons on the environmental assessment prepared to examine any environmental impacts of the proposed determinations for the subject cotton events. The petitions and the environmental assessment and any comments received are available for public review, and copies of the petitions and the environmental assessment are available as indicated in the FOR FURTHER INFORMATION CONTACT section of this notice.

After the comment period closes, APHIS will review the data submitted by the petitioner, all written comments received during the comment period, and any other relevant information. After reviewing and evaluating the comments on the petitions and the environmental assessment and other data and information, APHIS will furnish a response to the petitioner, either approving the petitions in whole or in part, or denying the petitions. APHIS will then publish a notice in the Federal Register announcing the regulatory status of the Mycogen/Dow insect-resistant cotton events Cry1F and Cry1Ac and the availability of APHIS's written decision.
