Ethofumesate; Modification and Closure of Reregistration Eligibility Decision; Notice of Availability
This notice announces EPA's intention to modify certain risk mitigation measures that were imposed as a result of the 2005 Reregistration Eligibility Decision (RED) for the pesticide ethofumesate, and opens a public comment period on these changes. EPA conducted this reassessment of the ethofumesate RED in response to new dermal absorption data submitted by the technical registrant, Bayer CropScience, Inc. These data allowed the Agency to modify its original assumption of 100% dermal absorption to 27% and thus modify the ethofumesate label requirements including: removing the 9-day re-entry interval for maintenance activity and adjusting the existing harvest prohibition for sod from 16 days to 3 days.

I. General Information ↑
A. Does this Action Apply to Me? ↑
This action is directed to the public in general, and may be of interest to a wide range of stakeholders including environmental, human health, and agricultural advocates; the chemical industry; pesticide users; and members of the public interested in the sale, distribution, or use of pesticides. Since others also may be interested, the Agency has not attempted to describe all the specific entities that may be affected by this action. If you have any questions regarding the applicability of this action to a particular entity, consult the person listed under FOR FURTHER INFORMATION CONTACT.
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 Code 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.
v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.
vi. Provide specific examples to illustrate your concerns and suggest alternatives.
vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.
viii. Make sure to submit your comments by the comment period deadline identified.
II. Background ↑
A. What Action is the Agency Taking? ↑
In 2005, EPA issued a RED for ethofumesate under section 4(g)(2)(A) of FIFRA. Subsequent to publication of this RED, the technical registrant submitted additional data to further refine ethofumesate use and exposure scenarios. After receiving an acceptable dermal absorption study from Bayer CropScience, the Agency refined the existing dermal absorption assumption of 100% in the RED to 27%. Using the 27% dermal absorption assumption from the new study, the Agency recalculated the re-entry intervals (REIs) and as a result will lower the prohibition for sod harvesting at maximum application rate from 16 days to 3 days and will no longer require a re-entry interval of 9 days for turf maintenance workers. The Agency has also updated the existing ethofumesate docket with additional memoranda addressing how the Agency refined the existing RED using the dermal absorption study. The docket also includes response to comments memoranda.
All comments should be submitted using the methods in ADDRESSES, and must be received by EPA on or before the closing date. Comments and proposals will become part of the Agency Docket for ethofumesate. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.
EPA will carefully consider all comments received by the closing date and will provide a Response to Comments Memorandum in the Docket and regulations.gov. If any comment significantly affects the document, EPA also will publish an amendment to the RED in the Federal Register. In the absence of substantive comments requiring changes, the ethofumesate RED will be implemented as it is now presented.
B. What is the Agency's Authority for Taking this Action? ↑
Section 4(g)(2) of FIFRA as amended directs that, after submission of all data concerning a pesticide active ingredient, “the Administrator shall determine whether pesticides containing such active ingredient are eligible for reregistration,” before calling in product specific data on individual end-use products and either reregistering products or taking other “appropriate regulatory action.”
Section 408(q) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(q), requires EPA to review tolerances and exemptions for pesticide residues in effect as of August 2, 1996, to determine whether the tolerance or exemption meets the requirements of section 408(b)(2) or (c)(2) of FFDCA. This review was completed on August 3, 2006.
