### 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-2005-0284. 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-2005-0284. 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 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 releasing for public comment its human health and environmental fate and effects risk assessments and related documents for resmethrin, a synthetic pyrethroid insecticide, and soliciting public comment on risk management ideas or proposals. Resmethrin is an insecticide used for indoor space treatments and crack and crevice treatments in residential and commercial areas. Resmethrin is also formulated as a ultra-low volume (ULV) outdoor mosquito adulticide. EPA developed the risk assessments and risk characterization for resmethrin through a modified version 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).

Resmethrin is a synthetic pyrethroid insecticide used in commercial and residential areas for treatment of many species of insects. Resmethrin is used for indoor space treatments, crack and crevice treatments, and as a mosquito adulticide ULV spray in residential and commercial areas. Currently there is one tolerance, set at 3 parts per million (ppm), for food items that have come in contact with resmethrin when it is used in food handling establishments (40 CFR 180.525). Resmethrin may be used as an insecticide by private citizens in their homes and may also be applied indoors by commercial pest control operators. It is also used by certified applicators as a ULV spray for outdoor mosquito control. Resmethrin is used alone, with other active ingredients, and in combination with synergists such as piperonyl butoxide, that increase the effectiveness of resmethrin. Approximately 50,000 pounds (lbs) of resmethrin are applied per year.

EPA is providing an opportunity, through this notice, for interested parties to provide comments and input on the Agency's risk assessments for resmethrin. Such comments and input could address, for example, the availability of additional data to further refine the risk assessments, such as the percent of food handling establishment actually treated with resmethrin, or mitigation options for ecological risk, or could address the Agency's risk assessment methodologies and assumptions as applied to this specific pesticide.

Through this notice, EPA also is providing an opportunity for interested parties to provide risk management proposals or otherwise comment on risk management for resmethrin. The current resmethrin human health risk assessment indicates a potential risk of concern from dietary exposure to products used in food handling establishments for control of insects. The assessment utilizes an assumption that one-hundred percent of food handling establishments are treated with resmethrin. This is a conservative assumption given that the total volume of resmethrin used in the United States is approximately 50,000 lbs annually, an amount that is not sufficient to treat all the food handling establishments in the United States. Thus, information on resmethrin use in food handling establishments, such as amount used and frequency of application, would be helpful to refine the dietary assessment. The current resmethrin human health risk assessment also indicates a potential risk of concern for products used by private citizens to treat enclosed spaces for insect control. The exposure assumptions used in the assessment include exposure for 3 days a year for 50 years treating 1,600 square feet of surface area with one 10 ounce (oz) spray can containing a maximum of 0.2% active ingredient (ai). The exposure duration used is less than or equal to 2 hours and the adult breathing rate is one cubic meter per hour. Information to confirm or refute these assumptions would be useful, as would suggestions for reducing exposure for this use.

EPA seeks to achieve environmental justice, the fair treatment and meaningful involvement of all people, regardless of race, color, national origin, or income, in the development, implementation, and enforcement of environmental laws, regulations, and policies. To help address potential environmental justice issues, the Agency seeks information on any groups or segments of the population who, as a result of their location, cultural practices, or other factors, may have atypical, unusually high exposure to resmethrin, compared to the general population.

                    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, the Agency is tailoring its public participation process to be commensurate with the level of risk, extent of use, complexity of the issues, and degree of public concern associated with each pesticide. For resmethrin, a modified, 4-Phase process with one comment period and ample opportunity for public consultation seems appropriate in view of its limited risk and use. However, if as a result of comments received during this comment period EPA finds that additional issues warranting further discussion are raised, the Agency may lengthen the process and include a second comment period, as needed.                

All comments should be submitted using the methods in Unit I.C. and must be received by EPA on or before the closing date. Comments will become part of the Agency Docket for resmethrin. Comments received after the close of the comment period will be marked “late” EPA is not required to consider these late comments.

### 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 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.
