### C. How and to Whom Do I Submit Comments?

You may submit comments electronically, by mail, or through hand delivery/courier. To ensure proper receipt by EPA, identify the appropriate docket ID number in the subject line on the first page of your comment. Please ensure that your comments are submitted within the specified comment period. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments. If you wish to submit CBI or information that is otherwise protected by statute, please follow the instructions in Unit I.D. Do not use EPA Dockets or e-mail to submit CBI or information protected by statute.

                    1.                     *Electronically*. If you submit an electronic comment as prescribed in this unit, EPA recommends that you include your name, mailing address, and an e-mail address or other contact information in the body of your comment. Also include this contact information on the outside of any disk or CD ROM you submit, and in any cover letter accompanying the disk or CD ROM. This ensures that you can be identified as the submitter of the comment and allows EPA to contact you in case EPA cannot read your comment due to technical difficulties or needs further information on the substance of your comment. EPA's policy is that EPA will not edit your comment, and any identifying or contact information provided in the body of a comment will be included as part of the comment that is placed in the official public docket, and made available in EPA's electronic public docket. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment.                

                    i.                     *EPA Dockets*. Your use of EPA's electronic public docket to submit comments to EPA electronically is EPA's preferred method for receiving comments. Go directly to EPA Dockets at                     *http://www.epa.gov/​edocket/​*, and follow the online instructions for submitting comments. Once in the system, select “search,” and then key in docket ID number OPP-2005-0084. The system is an “anonymous access” system, which means EPA will not know your identity, e-mail address, or other contact information unless you provide it in the body of your comment.                

                    ii.                     *E-mail*. Comments may be sent by e-mail to                     *opp-docket@epa.gov*, Attention: Docket ID Number OPP-2005-0084. In contrast to EPA's electronic public docket, EPA's e-mail system is not an “anonymous access” system. If you send an e-mail comment directly to the docket without going through EPA's electronic public docket, EPA's e-mail system automatically captures your e-mail address. E-mail addresses that are automatically captured by EPA's e-mail system are included as part of the comment that is placed in the official public docket, and made available in EPA's electronic public docket.                

                    iii.                     *Disk or CD ROM*. You may submit comments on a disk or CD ROM that you mail to the mailing address                           ( print page 53007)                        identified in Unit I.C.2.

### D. How Should I Submit CBI to the Agency?

Do not submit information that you consider to be CBI electronically through EPA's electronic public docket or by e-mail. You may claim information that you submit to EPA as CBI by marking any part or all of that information as CBI (if you submit CBI on disk or CD ROM, 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 CBI). Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.

                    In addition to one complete version of the comment that includes any 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 and EPA's electronic public docket. If you submit the copy that does not contain CBI on disk or CD ROM, mark the outside of the disk or CD ROM clearly that it does not contain CBI. Information not marked as CBI will be included in the public docket and EPA's electronic public docket without prior notice. If you have any questions about CBI or the procedures for claiming CBI, please consult the person listed under                     **FOR FURTHER INFORMATION CONTACT**                    .                

### E. What Should I Consider as I Prepare My Comments for EPA?

You may find the following suggestions helpful for preparing your comments:

1. Explain your views as clearly as possible.

2. Describe any assumptions that you used.

3. Provide any technical information and/or data you used that   support your views.

4. If you estimate potential burden or costs, explain how you arrived at your estimate.

5. Provide specific examples to illustrate your concerns.

6. Offer alternatives.

7. Make sure to submit your comments by the comment period deadline identified.

                    8. To ensure proper receipt by EPA, identify the appropriate docket ID number in the subject line on the first page of your response. It would also be helpful if you provided the name, date, and                     **Federal Register**                     citation related to your comments.                

## II. Background

### A. What Action is the Agency Taking?

EPA is making available the Agency's revised risk assessments, initially made available to the public for comment through a technical briefing on December 14, 1999, as well as related documents for dimethoate. EPA also is soliciting public comment on risk reduction options for dimethoate, namely, possible ways to mitigate drinking water risks, risks to workers, and risks to wildlife, as well as any data that may be available on the rate of conversion of dimethoate to omethoate during drinking water treatment. EPA developed the risk assessments for dimethoate as part of its public process for making pesticide reregistration eligibility and tolerance reassessment decisions. Through these programs, EPA is ensuring that pesticides meet current standards under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA).

Dimethoate is a systemic organophosphate insecticide used for control of a wide variety of insect pests on a number of fruit, vegetable, grain, and field crops, as well as ornamentals and non-cropland adjacent to agricultural fields.

EPA is providing an opportunity, through this notice, for interested parties to provide risk management proposals or otherwise comment on risk management for dimethoate. Risks of concern associated with the use of dimethoate are as follows:

1. Dietary risks from food and drinking water together exceed the Agency's level of concern on an acute basis for all population subgroups, and on a chronic basis for infants and children.

2. Risks to occupational handlers for some handler scenarios exceed the level of concern.

3. Post-application risks for some exposure scenarios exceed the level of concern.

4. The Agency's ecological levels of concern are exceeded for birds on an acute and chronic basis, mammals on an acute and chronic basis, freshwater fish on a chronic basis, and freshwater invertebrates on an acute and chronic basis.

In targeting these risks of concern, the Agency solicits information on effective and practical risk reduction measures.

                    EPA is applying the principles of public participation to all pesticides undergoing reregistration and tolerance reassessment. The Agency's Pesticide Tolerance Reassessment and Reregistration; Public Participation Process, published in the                     **Federal Register**                     on May 14, 2004, (69 FR 26819) (FRL-7357-9), explains that in conducting these programs, EPA is tailoring its public participation process to be commensurate with the level of risk, extent of use, complexity of issues, and degree of public concern associated with each pesticide. Due to its uses, risks, and other factors, dimethoate is being reviewed through the full 6-Phase public participation process.                

                    All comments should be submitted using the methods in Unit I. of the                     **SUPPLEMENTARY INFORMATION**                    , and must be received by EPA on or before the comment period deadline. Comments and proposals will become part of the official public docket for dimethoate. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.                

After considering comments received, EPA will develop and issue for comment the dimethoate IRED. The decisions presented in this IRED may be supplemented by further risk mitigation measures when EPA considers its cumulative assessment of the organophosphate pesticides.

### 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 FFDCA, 21 U.S.C. 346a(q), requires EPA to review                           ( print page 53008)                        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 is to be completed by August 3, 2006.
