If you submit an electronic comment, EPA recommends that you include your name and other contact information in the body of your comment and with any disk or CD ROM you submit. 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. Electronic files should avoid the use of special characters, any form of encryption, and be free of any defects or viruses.

Docket: All documents in the docket are listed in the docket index. Although listed in the index, some information is not publicly available, e.g., CBI or other information whose disclosure is restricted by statute. Certain other material, such as copyrighted material, is not placed on the Internet and will be publicly available only in hard copy form. Publicly available docket materials are available in the electronic docket at http://www.regulations.gov, or, if only available in hard copy, at the OPP Regulatory Public Docket at the location identified under “Delivery” and “Important Note.” The hours of operation for this Docket Facility are from 8:30 a.m. to 4 p.m., Monday through Friday, excluding legal holidays.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this Action Apply to Me?

-You may be potentially affected by this action if you are an agricultural producer, food manufacturer, or pesticide manufacturer. Potentially affected entities may include, but are not limited to:

-• Crop production (NAICS code 111).

-• Animal production (NAICS code 112).

-• Food manufacturing (NAICS code 311).

-• Pesticide manufacturing (NAICS code 32532).

-This listing is not intended to be exhaustive, but rather provides a guide for readers regarding entities likely to be affected by this action. Other types of entities not listed in this unit could also be affected. The North American Industrial Classification System (NAICS) codes have been provided to assist you and others in determining whether this action might apply to certain entities. 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. What Action is the Agency Taking?

-EPA is printing a summary of each pesticide petition received under section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, proposing the establishment or amendment of regulations in 40 CFR part 180 for residues of pesticide chemicals in or on various food commodities. EPA has determined that these pesticide petitions contain data or information regarding the elements set forth in FFDCA section 408(d)(2); however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data support granting of the pesticide petition. Additional data may be needed before EPA rules on this pesticide petition.

-Pursuant to 40 CFR 180.7(f), a summary of the petitions included in this notice, prepared by the petitioner along with a description of the analytical method available for the detection and measurement of the pesticide chemical residues is available on EPA's Electronic Docket at http://www.regulations.gov. To locate this information on the home page of EPA's Electronic Docket, select “Quick Search” and type the OPP docket ID number. Once the search has located the docket, clicking on the “Docket ID” will bring up a list of all documents in the docket for the pesticide including the petition summary.

New Tolerances

PP 3E6762. Interregional Research Project No. 4 (IR-4), 681 US Highway #1 South, North Brunswick, NJ 08902, proposes to establish a tolerance for the residues of bifenazate (1-methylethyl 2-(4-methoxy [1,1'-biphenyl]-3-yl)hydrazinecarboxylate) and diazinecarboxylic acid, 2-(4-methoxy-[1,1'-biphenyl]-3-yl), 1-methylethyl ester (expressed as bifenazate) in or on food commodities fruit, stone (Group 12) at 2.0 parts per million (ppm); and proposes to amend 40 CFR 180.572 by deleting the existing peach and nectarine tolerances since they are included in the fruit, stone (Group 12) tolerance of 2.0 ppm;

Amendment to Existing Tolerances

PP 5E6992. Proposes bifenazate tolerances for pea, garden at 0.2 ppm; pea, edible podded at 4.0 ppm; and vegetable, tuberous and corm (Subgroup 1C) at 0.01 ppm. A practical analytical method was developed for detecting and measuring residues of bifenazate in or on raw agricultural commodities. The method utilizes reverse phase high pressure liquid chromatography (HPLC) to separate bifenazate from matrix derived interferences, and oxidative coulometric electrochemical detection (OCED) for the identification and quantification of this analyte. Using this method, the limit of quantitation (LOQ) for bifenazate in stone and pome fruit, grapes, strawberries and cotton was 0.01 ppm. For hops, the LOQ was 0.05 ppm. The limit of detection for this method, which varies with matrix, is 0.005 ppm. The analytical method for bifenazate and its major metabolite, D3598, in animal samples was designed using the same principles invoked in the plant method with minor modifications. However, in animal samples, a separate aliquot of the extract was used to determine residues of A1530 and its sulfate (combined) in milk and meat samples (these metabolites appeared to be significant in goat metabolism studies). The extract was subjected to acid hydrolysis to convert the sulfate conjugate to A1530 before it was quantified by HPLC using fluorescence or OCED detectors.
