Environmental Protection Agency (EPA).
EPA is seeking comment on a draft White Paper that reviews data on the level in the human food supply of Cry9C protein from StarLink® corn grain. It concludes that the protein has been sufficiently removed from the human food supply to render the level of risk low enough that continued testing for the protein in yellow corn at dry mills and masa production facilities provides no added public health protection. The White Paper therefore recommends that the Food and Drug Administration (FDA) withdraw its guidance recommending testing yellow corn grain for Cry9C at dry mills and masa production facilities. Concurrent with this notice, the FDA is publishing for comment a notice in the Federal Register that FDA is considering withdrawing its guidance.

B. What Should I Consider as I Prepare My Comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through regulations.gov or e-mail. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then identify electronically within the disk or CD-ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.
2. Tips for preparing your comments. When submitting comments, remember to:
i. Identify the document by docket ID number and other identifying information (subject heading, Federal Register date and page number).
ii. Follow directions. The Agency may ask you to respond to specific questions or organize comments by referencing a Start Printed Page 58979Code of Federal Regulations (CFR) part or section number.
iii. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.
iv. Describe any assumptions and provide any technical information and/or data that you used.

What Action is the Agency Taking?
EPA is seeking comment on a draft White Paper that reviews data on the level in the human food supply of Cry9C protein from StarLink® corn grain. It concludes that the protein has been sufficiently removed from the human food supply to render the level of risk low enough that continued testing for the protein in yellow corn at dry mills and masa production facilities provides no added public health protection. StarLink® refers to a variety of corn genetically engineered to express the protein Cry9C. Because Cry9C is toxic to various insect pests of corn, Cry9C acts as a pesticide and was regulated by the U.S. Environmental Protection Agency (EPA or Agency) under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA). Under FIFRA and FFDCA, a company seeking to sell or distribute a pesticide must submit data demonstrating that it will not cause unreasonable adverse effects on the environment and that any residues in food will be safe, i.e., there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.
Aventis Agroscience, Inc. (Aventis) submitted data on the safety of StarLink® and applied for approvals under FIFRA and FFDCA. EPA concluded that the available data did not provide enough information to support a conclusion that Cry9C was not a potential human allergen, but that all other information indicated that it would not pose any other types of risks to human health or the environment. Accordingly, in 1998 EPA registered StarLink® for commercial use, provided that all grain derived from StarLink® corn was directed to domestic animal feed or to industrial uses (e.g., biofuels). The intent of requiring all StarLink® to be segregated as either animal feed or for industrial use was to preclude any occurrence of the potentially allergenic Cry9C in human food. The registration contained several specific requirements designed to ensure that no StarLink® grain entered the human food supply. Following registration, relatively small quantities of StarLink® were planted in the United States: 9,018 acres in 1998, 247,694 acres in 1999, and 350,000 acres in 2000, with the largest planting representing less than half a percent of the total acreage planted to corn in the United States.
In September 2000, residues from StarLink® were detected in taco shells, indicating that it had entered the human food supply. In response to these detections, Aventis requested cancellation of the StarLink® registration, http://www.epa.gov/fedrgstr/EPA-PEST/2001/January/Day-18/p1522.htm. In addition, working with U.S. Department of Agriculture (USDA), Food and Drug Administration (FDA), EPA, and the food industry, Aventis undertook a program to remove all StarLink® from the food supply. Among other measures, FDA recommended that facilities engaged in the dry milling or masa production of yellow corn test all incoming shipments of yellow corn for the possible presence of Cry9C and that they divert all shipments testing positive to domestic feed or industrial use.
At the same time, Aventis also requested that EPA reconsider its position that the available data did not provide enough information to support a conclusion that Cry9C was not a potential human allergen. Aventis provided additional data and analysis to support its position that the allergenic risks of Cry9C were very small. Most of the arguments advanced by Aventis involved the assertion that exposure to Cry9C was so low, especially after the full implementation of the containment and removal program, that there would be no threat to public health. In 2000 and 2001 EPA held a series of meetings of its FIFRA Scientific Advisory Panel (SAP or Panel) to evaluate the scientific issues raised by the new data, analysis, and arguments.
Following the cancellation of the StarLink® registration, Aventis established a separate corporate entity, StarLink Logistics Inc. (SLLI), as the successor to Aventis' interest in StarLink® products. SLLI oversees the StarLink®. Enhanced Stewardship Program, through which SLLI and the U.S. corn millers have continued the efforts to contain and remove Cry9C from the human food supply. SLLI also maintains a monitoring database containing the test results from more than 4 million tests from over 4 billion bushels of corn collected by dry milling facilities and other corn handling operations. These tests were carried out according to guidance developed by FDA and USDA's Grain Inspection, Packers and Stockyards Administration (GIPSA), and the federal government considers the data reliable.
In 2005, SLLI commissioned Exponent, Inc., to prepare a new exposure assessment of the levels of Cry9C present in the U.S. food supply for submission to EPA. SLLI provided supplemental information in 2006 that updates the 2005 exposure assessment and that quantitatively characterizes the impact of the monitoring and diversion program on exposure to Cry9C. The USDA's Agricultural Research Service (ARS) provided the analytical data on Cry9C concentrations in corn grain used in Exponent's exposure analysis. In addition, the ARS provided results from testing corn seeds from the 1970s and 1980s (that is, before Cry9C was ever bioengineered into corn) for the possible presence of naturally occurring Cry9C or other proteins that give a positive reaction in the Cry9C test. GIPSA conducted additional testing to verify the results of the ARS laboratory.
The draft EPA White Paper concludes that the protein has been sufficiently removed from the human food supply to render the level of risk low enough that continued testing for the protein in yellow corn at dry mills and masa production facilities provides no added public health protection. The White Paper therefore recommends that FDA withdraw its guidance recommending testing yellow corn grain for Cry9C at dry mills and masa production facilities.
