Acephate, Cacodylic acid, Dicamba, Dicloran et al.; Proposed

Tolerance Actions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to revoke certain tolerances for the fungicides dicloran and thiophanate-methyl; the herbicides EPTC, hexazinone, picloram, and propazine; the defoliant and herbicide cacodylic acid; the plant growth regulator and herbicide diquat, the insecticides disulfoton, malathion, methamidophos, methomyl, phosmet, piperonyl butoxide, pyrethrins, and thiodicarb; the fumigant antimicrobial and insecticide methyl bromide, the nematicides/ insecticides ethoprop and fenamiphos, the insecticide synergist N-octyl bicycloheptene dicarboximide, and the tolerance exemptions for the insecticide/miticide pyrethrum and insecticide synergist N-octyl bicycloheptene dicarboximide. In addition, EPA is proposing to remove certain expired tolerances for disulfoton, fenamiphos, and thiophanate- methyl. Also, EPA is proposing to modify certain tolerances for the fungicide thiophanate-methyl, herbicides dicamba, EPTC, hexazinone and picloram, and insecticide synergist N-octyl bicycloheptene dicarboximide. In addition, EPA is proposing to establish new tolerances for the fungicide thiophanate-methyl and the herbicides

EPTC, hexazinone, and picloram. Also, EPA is proposing to reinstate specific tolerances for methamidophos residues as a result of the application of the insecticide acephate. The regulatory actions proposed in this document are in follow-up to the Agency's reregistration program under the Federal Insecticide, Fungicide, and

Rodenticide Act (FIFRA), and tolerance reassessment program under the

Federal Food, Drug, and Cosmetic Act (FFDCA), section 408(q).

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. To determine whether you or your business may be affected by this action, you should carefully examine the applicability provisions in Unit II.A. 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

Page 28157

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.

C. What Can I do if I Wish the Agency to Maintain a Tolerance that the

Agency Proposes to Revoke?

This proposed rule provides a comment period of 60 days for any person to state an interest in retaining a tolerance proposed for revocation. If EPA receives a comment within the 60-day period to that effect, EPA will not proceed to revoke the tolerance immediately.

However, EPA will take steps to ensure the submission of any needed supporting data and will issue an order in the Federal Register under

FFDCA section 408(f), if needed. The order would specify data needed and the timeframes for its submission, and would require that within 90 days some person or persons notify EPA that they will submit the data.

If the data are not submitted as required in the order, EPA will take appropriate action under FFDCA.

EPA issues a final rule after considering comments that are submitted in response to this proposed rule. In addition to submitting comments in response to this proposal, you may also submit an objection at the time of the final rule. If you fail to file an objection to the final rule within the time period specified, you will have waived the right to raise any issues resolved in the final rule. After the specified time, issues resolved in the final rule cannot be raised again in any subsequent proceedings.

II. Background

A. What Action is the Agency Taking?

EPA is proposing to revoke, modify, and establish specific tolerances for residues of the fungicides dicloran and thiophanate- methyl; the herbicides dicamba, EPTC, hexazinone, picloram, and propazine; the defoliant and herbicide cacodylic acid; the plant growth regulator and herbicide diquat, the insecticides disulfoton, malathion, methamidophos, methomyl, phosmet, piperonyl butoxide, pyrethrins, and thiodicarb; the fumigant antimicrobial and insecticide methyl bromide, the nematicides/insecticides ethoprop and fenamiphos; and the insecticide synergist N-octyl bicycloheptene dicarboximide; revoke the tolerance exemptions for the insecticide/miticide pyrethrum and insecticide synergist N-octyl bicycloheptene dicarboximide; remove certain expired tolerances for disulfoton, fenamiphos, and thiophanate- methyl; and reinstate specific tolerances for methamidophos residues as a result of the application of the insecticide acephate in or on commodities listed in the regulatory text.

EPA is proposing these tolerance/tolerance exemption actions to implement the tolerance recommendations made during the reregistration and tolerance reassessment processes (including follow-up on canceled or additional uses of pesticides). As part of these processes, EPA is required to determine whether each of the amended tolerances meets the safety standard of FFDCA. The safety finding determination of

``reasonable certainty of no harm'' is discussed in detail in each

Reregistration Eligibility Decision (RED) and Report of the Food

Quality Protection Act (FQPA) Tolerance Reassessment Progress and Risk

Management Decision (TRED) for the active ingredient. REDs and TREDs recommend the implementation of certain tolerance actions, including modifications to reflect current use patterns, meet safety findings, and change commodity names and groupings in accordance with new EPA policy. Printed copies of many REDs and TREDs may be obtained from

EPA's National Service Center for Environmental Publications (EPA/

NSCEP), P.O. Box 42419, Cincinnati, OH 45242-2419; telephone number: 1- 800-490-9198; fax number: 1-513-489-8695; Internet at http:// www.epa.gov/ncepihom and from the National Technical Information

Service (NTIS), 5285 Port Royal Rd., Springfield, VA 22161; telephone number: 1-800-553-6847 or (703) 605-6000; Internet at http:// www.ntis.gov. Electronic copies of REDs and TREDs are available on the

Internet in public dockets; REDs for cacodylic acid (EPA-HQ-OPP-2006- 0201), dicamba (EPA-HQ-OPP-2005-0479), ethoprop (EPA-HQ-OPP-2002-0269), malathion (EPA-HQ-OPP-2004-0348), N-octyl bicycloheptene dicarboximide

(EPA-HQ-OPP-2005-0040), pyrethrum (see pyrethrins RED in EPA-HQ-OPP- 2005-0043), and thiophanate-methyl (EPA-HQ-OPP-2004-0265), and TREDs for hexazinone (EPA-HQ-OPP-2002-0188) and propazine (EPA-HQ-OPP-2005- 0496) at http://www.regulations.gov and REDs for acephate, EPTC, methamidophos, phosmet, and picloram at http://www.epa.gov/pesticides/ reregistration/status.htm.

The selection of an individual tolerance level is based on crop field residue studies designed to produce the maximum residues under the existing or proposed product label. Generally, the level selected for a tolerance is a value slightly above the maximum residue found in such studies, provided that the tolerance is safe. The evaluation of whether a tolerance is safe is a separate inquiry. EPA recommends the raising of a tolerance when data show that:

Lawful use (sometimes through a label change) may result in a higher residue level on the commodity.

The tolerance remains safe, notwithstanding increased residue level allowed under the tolerance.

In REDs, Chapter IV on ``Risk management, Reregistration, and Tolerance reassessment'' typically describes the regulatory position, FQPA assessment, cumulative safety determination, determination of safety for U.S. general population, and safety for infants and children. In particular, the human health risk assessment document which supports the RED describes risk exposure estimates and whether the Agency has concerns. In TREDs, the Agency discusses its evaluation of the dietary risk associated with the active ingredient and whether it can determine that there is a reasonable certainty (with appropriate mitigation) that no harm to any population subgroup will result from

Page 28158

aggregate exposure. EPA also seeks to harmonize tolerances with international standards set by the Codex Alimentarius Commission, as described in Unit III.

Explanations for proposed modifications in tolerances can be found in the RED and TRED document and in more detail in the Residue

Chemistry Chapter document which supports the RED and TRED. Copies of the Residue Chemistry Chapter documents are found in the Administrative

Record and electronic copies for dicamba, ethoprop (Data Requirements and Tolerance Reassessment), hexazinone, malathion, N-octyl bicycloheptene dicarboximide, propazine, pyrethrum (see pyrethrins), and thiophanate-methyl can be found under their respective public docket ID numbers, identified in Unit II.A. Electronic copies are also available in public dockets for acephate (EPA-HQ-OPP-2007-0445), cacodylic acid (EPA-HQ-OPP-2006-0201), methamidophos (EPA-HQ-OPP-2007- 0261), and phosmet (EPA-HQ-OPP-2008-0834), and for EPTC in the public docket for this proposed rule. Electronic copies are available through

EPA's electronic public docket and comment system, regulations.gov at http://www.regulations.gov. You may search for this proposed rule under docket ID number EPA-HQ-OPP-2010-0262, then click on that docket ID number to view its contents.

EPA has determined that the aggregate exposures and risks are not of concern for the above mentioned pesticide active ingredients based upon the data identified in the RED or TRED which lists the submitted studies that the Agency found acceptable.

EPA has found that the tolerances/tolerance exemptions that are proposed in this document to be modified, are safe; i.e., that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residues, in accordance with FFDCA section 408(b)(2)(C). (Note that changes to tolerance nomenclature do not constitute modifications of tolerances).

These findings are discussed in detail in each RED or TRED. The references are available for inspection as described in this document under SUPPLEMENTARY INFORMATION.

In addition, EPA is proposing to revoke certain specific tolerances/tolerance exemptions because either they are no longer needed or are associated with food uses that are no longer registered under FIFRA. Those instances where registrations were canceled were because the registrant failed to pay the required maintenance fee and/ or the registrant voluntarily requested cancellation of one or more registered uses of the pesticide. It is EPA's general practice to propose revocation of those tolerances/tolerance exemptions for residues of pesticide active ingredients on crop uses for which there are no active registrations under FIFRA, unless any person in comments on the proposal indicates a need for the tolerance to cover residues in or on imported commodities or legally treated domestic commodities. 1. Acephate. In order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the tolerance expression in 40 CFR 180.108(a)(1) to read as follows:

Tolerances are established for residues of acephate, O,S- dimethyl acetyl phosphoramidothioate, including its metabolites and degradates other than methamidophos, in or on the commodities in the table in this paragraph. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only acephate, O,S-dimethyl acetyl phosphoramidothioate, in or on the commodity.

In the Federal Register of January 29, 2008 (73 FR 5104) (FRL-8348- 8), EPA revised the tolerance expression for acephate in 40 CFR 180.108 from the combined residues of acephate, O,S-dimethyl acetyl phosphoramidothioate, and methamidophos, O,S-dimethyl phosphoramidothioate, to residues of acephate per se, removed the terminology ``of which no more than 1 ppm, 0.5 ppm, or 0.1 ppm is O,S- dimethyl phosphoramidothioate'' from tolerances on bean (succulent and dry); Brussels sprouts; cauliflower; celery; cranberry; lettuce, head; mint hay, and pepper; and footnoted that residues of the acephate metabolite, methamidophos, are regulated under 40 CFR 180.315. However, the basis for this action was in error, as methamidophos tolerances for bean, dry, seed; bean, succulent; cranberry; peppermint, tops; and spearmint, tops had not in fact been established in 40 CFR 180.315. To remedy this inadvertent error, the Agency proposes to reinstate the 40

CFR 180.108 tolerances. Consequently, EPA is proposing to separate tolerances for residues of methamidophos from the application of acephate in newly designated 40 CFR 180.108(a)(3), with the introductory text to read as follows:

Tolerances are established for residues of methamidophos, O,S- dimethyl phosphoramidothioate, including its metabolites and degradates, in or on the commodities in the table in this paragraph as a result of the application of acephate. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only methamidophos, O,S-dimethyl phosphoramidothioate, in or on the commodity.

In addition, EPA is proposing to reinstate the tolerances in 40 CFR 180.108(a)(3) on bean, dry, seed at 1 ppm; bean, succulent at 1 ppm;

Brussels sprouts at 0.5 ppm; cauliflower at 0.5 ppm (which is in harmony with the Codex maximumn residue limits (MRL) of 0.5 milligrams/ kilogram (mg/kg) on cauliflower); celery 1 ppm; cranberry at 0.1 ppm; lettuce, head at 1 ppm; pepper at 1 ppm; and reinstate mint hay, revising the tolerance terminology to peppermint, tops at 1 ppm and spearmint, tops at 1 ppm. On January 29, 2008, EPA published a final rule in the Federal Register (73 FR 5104) (FRL-8348-8), which finalized tolerance actions for several active ingredients, including acephate, and which increased the tolerances in 40 CFR 180.108(a)(1) for acephate residues in or on mint hay (peppermint, tops and spearmint, tops) from 15.0 to 27.0 ppm. Consequently, methamidophos residues resulting from acephate application are expected by the Agency to be increased from 1.0 to 2.0 ppm in or on peppermint, tops and spearmint, tops. However, the Agency is not proposing an increase on the peppermint, tops and spearmint, tops tolerances for methamidophos residues at this time.

Based on available data that showed residues of acephate were as high as 0.02 ppm for only one of seven exposed food items following both a spot treatment and crack/crevice treatment for rooms treated with acephate at the 1x rate and residues of methamidophos were undetectable from these acephate treatments, the Agency determined that a tolerance level of 0.02 ppm for acephate residues was appropriate and that there was no expectation of methamidophos residues and therefore no methamidophos tolerance was needed concerning food handling establishments. Consequently, compliance with the tolerance at 0.02 ppm in 40 CFR 180.108(a)(2) should continue to be determined by measuring only acephate residues. However, in order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the tolerance expression in 40 CFR 180.108(a)(2), to read as follows:

A tolerance of 0.02 ppm is established for residues of acephate,

O,S-dimethyl acetyl phosphoramidothioate, including its metabolites and degradates other than methamidophos, in or on all food items

Page 28159

(other than those already covered by a higher tolerance as a result of use on growing crops) in food handling establishments where food and food products are held, processed, prepared and served, including food service, manufacturing and processing establishments, such as restaurants, cafeterias, supermarkets, bakeries, breweries, dairies, meat slaughtering and packing plants, and canneries, where application of acephate shall be limited solely to spot and/or crack and crevice treatment (a coarse, low-pressure spray shall be used to avoid atomization or splashing of the spray for spot treatments; equipment capable of delivering a pin-stream of insecticide shall be used for crack and crevice treatments). Spray concentration shall be limited to a maximum of 1.0 percent active ingredient. Contamination of food or food-contact surfaces shall be avoided. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only acephate, O,S-dimethyl acetyl phosphoramidothioate, in or on the commodity.

Because EPA is proposing to revise 40 CFR 180.108(a)(2) and include text from 40 CFR 180.108(a)(2)(i) and (a)(2)(ii), existing paragraphs

(a)(2)(i) and (a)(2)(ii) are no longer needed. Therefore, EPA is proposing to remove 40 CFR 180.108(a)(2)(i) and (a)(2)(ii).

In order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the regional tolerance expression in 40 CFR 180.108(c) to read as follows:

A tolerance with a regional registration is established for residues of acephate, O,S-dimethyl acetyl phosphoramidothioate, including its metabolites and degradates other than methamidophos, in or on the commodity in the table in this paragraph. Compliance with the tolerance level specified in this paragraph is to be determined by measuring only acephate, O,S-dimethyl acetyl phosphoramidothioate, in or on the commodity.

Also, EPA is proposing to revise the table footnote in 40 CFR 180.108(a)(1) and add a table footnote in 40 CFR 180.108(c) to read as follows:

Where there is a direct use of methamidophos on the commodity, residues of methamidophos resulting from methamidophos application are regulated under 40 CFR 180.315.

There are Codex MRLs for acephate, including those on beans, except broad bean and soya bean at 5 mg/kg, cauliflower at 2 mg/kg, cranberry at 0.5 mg/kg, peppers, chili (dry) at 50 mg/kg, and other commodities. 2. Cacodylic acid. In the Federal Register notice of July 8, 2009

(74 FR 32596) (FRL-8422-6), EPA issued a notice regarding EPA's announcement of the receipt of requests from registrants to voluntarily cancel certain registrations, including ones for cacodylic acid (and sodium salt) and therefore terminate the last cacodylic acid (and sodium salt) uses in or on cotton. After the close of the 30-day comment period, EPA approved cancellation of certain registrations, including the cacodylic acid (and sodium salt) registrations for uses in or on cotton and issued a cancellation order in the Federal Register notice of September 30, 2009 (74 FR 50187)(FRL-8437-7), made them effective on September 30, 2009, and prohibited the registrants for the canceled cacodylic acid (and sodium salt) registrations to sell and distribute existing stocks after December 31, 2009. Also, EPA prohibited persons other than the registrant to sell and distribute the canceled cacodylic acid (and sodium salt) existing stocks after

December 31, 2010. The Agency believes that end users will have had sufficient time to exhaust those existing stocks and for treated cotton commodities to have cleared the channels of trade by January 1, 2012.

The termination of the last cacodylic acid (and sodium salt) uses in or on cotton means that the tolerance will no longer be needed and should be revoked with an expiration/revocation date. Therefore, EPA is proposing to revoke the tolerance in 40 CFR 180.311(a) on cotton, undelinted seed with an expiration/revocation date of January 1, 2012.

Currently, tolerances are expressed for the defoliant cacodylic acid in 40 CFR 180.311(a) for residues of cacodylic acid

(dimethylarsinic acid), expressed as As2O3. In order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the tolerance expression in 40 CFR 180.311(a) to read as follows:

A tolerance is established for residues of the defoliant cacodylic acid, dimethylarsinic acid, including its metabolites and degradates, in or on the commodity in the table in this paragraph.

Compliance with the tolerance level specified in this paragraph is to be determined by measuring only those cacodylic acid residues convertible to As2O3, expressed as the stoichiometric equivalent of cacodylic acid, in or on the commodity.

There are no Codex MRLs for cacodylic acid. 3. Dicamba. Based on available processing data that showed an average concentration factor of 24.4X for molasses and the Highest

Average Field Trial (HAFT) residue of 0.183 ppm for sugarcane, EPA determined that the expected combined dicamba residues of concern in sugarcane molasses are 4.465 ppm, and that the currently established tolerance of 2.0 ppm for sugarcane molasses should be increased from 2.0 to 5.0 ppm. Therefore, the Agency is proposing to increase the tolerance in 40 CFR 180.227(a)(1) on sugarcane, molasses to 5.0 ppm.

The Agency determined that the increased tolerance is safe; i.e., there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue.

Based on available sugarcane field trial data that showed combined dicamba residues of concern as high as 0.2 ppm in or on sugarcane harvested 87-173 days following a single layby application at 2.0 lb dicamba acid equivalents per acre (ae/A), EPA determined that the tolerance should be increased from 0.1 to 0.3 ppm. While the available data, conducted at an application rate of 2.0 lb dicamba ae/A, do not support the maximum seasonal single/yearly rate of 2.8 lb dicamba ae/A that was listed in the Dicamba Master Use Profile, the Agency determined that the available data was adequate provided the registrants revise their product labels to specify a maximum seasonal rate of 2.0 lb dicamba ae/A and an 87-day preharvest interval (PHI) for sugarcane or submit additional data on sugarcane reflecting a maximum single/yearly rate of 2.8 lb dicamba ae/A. In response to the Data

Call-In (DCI) of June 27, 2008 that was issued to registrants, including the basic manufacturer BASF, BASF requested a waiver of the sugarcane study at 2.8 lb dicamba ae/A and cited MRID 44089302, and accepted rate limitations of 1 lb dicamba ae/A for single application, and an annual rate limitation of 2 lb dicamba ae/A. The Agency considers that available data to be sufficient provided product labels specify a maximum seasonal rate of 2.0 lb dicamba ae/A and an 87-day

PHI for sugarcane. Therefore, because the current tolerance on sugarcane, cane at 0.1 ppm is too low, based on the available data, EPA is proposing to increase the tolerance in 40 CFR 180.227(a)(1) on sugarcane, cane to 0.3 ppm. The Agency determined that the increased tolerance is safe; i.e., there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue.

In order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the tolerance expression in 40 CFR 180.227(a)(1) to read as follows:

Tolerances are established for residues of the herbicide dicamba, 3,6-dichloro-o-anisic

Page 28160

acid, including its metabolites and degradates, in or on the commodities in the table in this paragraph. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of dicamba, 3,6-dichloro-o-anisic acid, and its metabolite, 3,6-dichloro-5-hydroxy-o-anisic acid, calculated as the stoichiometric equivalent of dicamba, in or on the commodity.

In order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the tolerance expression in 40 CFR 180.227(a)(2) to read as follows:

Tolerances are established for residues of the herbicide dicamba, 3,6-dichloro-o-anisic acid, including its metabolites and degradates, in or on the commodities in the table in this paragraph.

Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of dicamba, 3,6-dichloro- o-anisic acid, and its metabolite, 3,6-dichloro-2-hydroxybenzoic acid, calculated as the stoichiometric equivalent of dicamba, in or on the commodity.

In order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the tolerance expression in 40 CFR 180.227(a)(3) to read as follows:

Tolerances are established for residues of the herbicide dicamba, 3,6-dichloro-o-anisic acid, including its metabolites and degradates, in or on the commodities in the table in this paragraph.

Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of dicamba, 3,6-dichloro- o-anisic acid, and its metabolites, 3,6-dichloro-5-hydroxy-o-anisic acid, and 3,6-dichloro-2-hydroxybenzoic acid, calculated as the stoichiometric equivalent of dicamba, in or on the commodity.

There are no Codex MRLs for dicamba. 4. Dicloran (DCNA). On December 2, 2009, EPA published a notice in the Federal Register (74 FR 63151) (FRL-8800-4) that announced the

Agency's receipt of requests from the registrants to voluntarily amend certain dicloran registrations and therefore terminate the last dicloran uses on carrots. EPA approved amendment of the affected DCNA registrations by publishing a cancellation order on March 31, 2010 in the Federal Register (75 FR 16105) (FRL-8815-8) and made them effective on November 2, 2010, and permitted the dicloran registrant to sell and distribute existing dicloran stocks (concerning the last uses for carrots) until November 2, 2010. For all affected dicloran products, the Agency permitted persons other than the registrant to sell and distribute existing stocks and use of those cancelled products until exhaustion. However, the Agency believes that end users will have had sufficient time to exhaust those existing stocks and for treated carrot commodities to have cleared the channels of trade by November 2, 2011.

Therefore, EPA is proposing to revoke the tolerance in 40 CFR 180.200(a)(1) for carrot, roots, postharvest with an expiration/ revocation date of November 2, 2011.

In order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the tolerance expression in 40 CFR 180.200(a)(1) to read as follows:

Tolerances are established for residues of the fungicide dicloran, 2,6-dichloro-4-nitroaniline, including its metabolites and degradates, in or on the commodities in the table in this paragraph.

Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only dicloran, 2,6-dichloro-4- nitroaniline, in or on the commodity. Unless otherwise specified, these tolerances prescribed in this paragraph provide for residues from preharvest application only.

There are Codex MRLs for dicloran, including an MRL on carrot at 15 mg/kg, and MRLs on other plant commodities. 5. Diquat. Currently, the only active registrations for diquat use on both sorghum grain and soybeans are for seed crops, and both uses have restrictions to not graze or feed treated forage to livestock and not use seed from treated plants for food, feed, or oil purposes. Given the restrictions, such uses are considered by the Agency to be non- food, and therefore the tolerances are no longer needed and should be revoked. Consequently, EPA is proposing to revoke the tolerances in 40

CFR 180.226(a)(1) on sorghum, grain, grain and soybean, seed.

There are Codex MRLs for diquat on sorghum at 2 mg/kg and on soybean (dry) at 0.2 mg/kg. 6. Disulfoton. On July 22, 2009, EPA published a notice in the

Federal Register (74 FR 36204) (FRL-8427-2) that announced the Agency's receipt of requests from the registrants to voluntarily cancel all disulfoton and methamidophos registrations and therefore terminate the last disulfoton and methamidophos products registered for use in the

United States, including the last disulfoton uses on asparagus, lima and snap beans, broccoli, Brussels sprouts, cabbage, cauliflower, coffee, cotton, and lettuce. EPA approved cancellation of the registrations by publishing a cancellation order on September 23, 2009 in the Federal Register (74 FR 48551) (FRL-8437-1) and made them effective on September 23, 2009, and permitted the disulfoton registrants to sell and distribute existing disulfoton stocks

(concerning the last uses for asparagus, lima and snap beans, broccoli,

Brussels sprouts, cabbage, cauliflower, cotton, and lettuce) until

December 31, 2010 and stocks of a single registration (264-723) with the last coffee use until June 30, 2011. For all affected disulfoton products, the Agency permitted persons other than the registrant to sell and distribute existing stocks and use of those cancelled products until exhaustion. However, the Agency believes that end users will have had sufficient time to exhaust those existing stocks and for treated asparagus, lima and snap beans, broccoli, Brussels sprouts, cabbage, cauliflower, cotton, and lettuce commodities to have cleared the channels of trade by December 31, 2012 and treated coffee commodities to have cleared the channels of trade by June 30, 2013. Therefore, EPA is proposing to revoke the tolerances in 40 CFR 180.183(a) for bean, lima; bean, snap, succulent; broccoli; Brussels sprouts; cabbage; cauliflower; cotton, undelinted seed; lettuce, head; and lettuce, leaf with expiration/revocation dates of December 31, 2012. Also, because there had been only active FIFRA section 24(c) registrations for use of disulfoton on asparagus, EPA is proposing to revoke the regional tolerance in 40 CFR 180.183(c) on asparagus with an expiration/ revocation date of December 31, 2012. In addition, EPA is proposing to revoke the tolerance in 40 CFR 180.183(a) for coffee, green bean with an expiration/revocation date of June 30, 2013.

Because the tolerances for combined disulfoton residues of concern expired on October 14, 2009, EPA is proposing to remove the tolerances in 40 CFR 180.183(a) on spinach and tomato. Also, because the tolerances for combined disulfoton residues of concern expired on

January 30, 2010, EPA is proposing to remove the tolerances in 40 CFR 180.183(a) on barley, grain; barley, straw; cattle, fat; cattle, meat; cattle, meat byproducts; goat, fat; goat, meat; goat, meat byproducts; grain, aspirated fractions; hog, fat; hog, meat; hog, meat byproducts; horse, fat; horse, meat; horse, meat byproducts; milk; peanut; pepper; potato; sheep, fat; sheep, meat; sheep, meat byproducts; wheat, grain; wheat, hay; and wheat, straw.

In order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the section heading in 40 CFR 180.183 from O,O-diethyl S-(2-

Page 28161

(ethylthio)ethyl) phosphorodithioate to disulfoton and revise the introductory text containing the tolerance expression in 40 CFR 180.183(a) to read as follows:

Tolerances are established for residues of the insecticide disulfoton, O,O-diethyl S-(2-(ethylthio)ethyl) phosphorodithioate, including its metabolites and degradates, in or on the commodities in the table in this paragraph. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of disulfoton, O,O-diethyl S-(2-(ethylthio)ethyl) phosphorodithioate, and its metabolites demeton-S,O,O-diethyl S-(2-

(ethylthio)ethyl) phosphorothioate; disulfoton sulfoxide, O,O- diethyl S-(2-(ethylsulfinyl)ethyl) phosphorodithioate; disulfoton oxygen analog sulfoxide, O,O-diethyl S-(2-(ethylsulfinyl)ethyl) phosphorothioate, disulfoton sulfone, O,O-diethyl S-(2-

(ethylsulfonyl)ethyl) phosphorodithioate; and disulfoton oxygen analog sulfone, O,O-diethyl S-(2-(ethylsulfonyl)ethyl) phosphorothioate; calculated as the stoichiometric equivalent of disulfoton, in or on the commodity.

In order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the regional tolerance expression in 40 CFR 180.183(c) to read as follows:

A tolerance with regional registration is established for residues of the insecticide disulfoton, O,O-diethyl S-(2-

(ethylthio)ethyl) phosphorodithioate, including its metabolites and degradates, in or on the commodity in the table in this paragraph.

Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of disulfoton, O,O- diethyl S-(2-(ethylthio)ethyl) phosphorodithioate, and its metabolites demeton-S, O,O-diethyl S-(2-(ethylthio)ethyl) phosphorothioate; disulfoton sulfoxide, O,O-diethyl S-(2-

(ethylsulfinyl)ethyl) phosphorodithioate; disulfoton oxygen analog sulfoxide, O,O-diethyl S-(2-(ethylsulfinyl)ethyl) phosphorothioate, disulfoton sulfone, O,O-diethyl S-(2-(ethylsulfonyl)ethyl) phosphorodithioate; and disulfoton oxygen analog sulfone, O,O- diethyl S-(2-(ethylsulfonyl)ethyl) phosphorothioate; calculated as the stoichiometric equivalent of disulfoton, in or on the commodity.

There are Codex MRLs for disulfoton, including those on asparagus at 0.02 mg/kg, coffee beans at 0.2 mg/kg, common bean (pods and/or immature seeds) at 0.2 mg/kg, cotton, seed at 0.1 mg/kg, and other commodities. 7. EPTC. Because cotton forage is no longer considered by the

Agency to be a significant livestock feed commodity as delineated in

``Table 1.--Raw Agricultural and Processed Commodities and Feedstuffs

Derived from Crops,'' which is found in Residue Chemistry Test

Guidelines OPPTS 860.1000, dated August 1996 (available at http:// www.epa.gov/opptsfrs/publications/OPPTS_Harmonized/860_Residue_

Chemistry_Test_Guidelines/Series/), EPA determined that the tolerance is no longer needed, and therefore should be revoked. Consequently, the

Agency is proposing to revoke the tolerance in 40 CFR 180.117 for residues of S-ethyl dipropylthiocarbamate (EPTC) in or on cotton, forage.

Because there have been no active S-ethyl dipropylthiocarbamate registrations in the United States for use on asparagus, small fruits

(including strawberries), flax seeds, and pineapples for more than 10 years, the tolerances are no longer needed and therefore should be revoked. Consequently, EPA is proposing to revoke the tolerances in 40

CFR 180.117 on asparagus; fruit, small; strawberry; flax, seed; and pineapple.

Because castor beans and oil products are not consumed by humans or livestock, EPA determined that the tolerance is no longer needed and therefore should be revoked. Consequently, EPA is proposing to revoke the tolerance in 40 CFR 180.117 on castorbean, seed.

EPA is proposing, in 40 CFR 180.117, to remove the ``(N)'' designation from all entries to conform to current Agency administrative practice (``N'' designation means negligible residues).

Also, tolerances are currently established in 40 CFR 180.117 for negligible residues of the herbicide S-ethyl dipropylthiocarbamate, also called EPTC. EPA determined that EPTC plant residues of toxicological concern are EPTC, EPTC sulfoxide, EPTC sulfone, and the

EPTC conjugates (glutathione, cysteine, N-malonyl cysteine, S-lactic acid, and O-malonyl S-lactic acid conjugates). However, the Agency concurred with the registrant's position that development of a single enforcement analytical method that can detect each of these residues was not feasible. Because development of an enforcement analytical method for the hydroxylated metabolites (S-ethyl (2- hydroxypropyl)propylcarbamothioate, S-(2- hydroxyethyl)dipropylcarbamothioate, and S-ethyl (3- hydroxypropyl)propylcarbamothioate) was feasible, the Agency concurred with the registrant's recommendation that EPTC and its hydroxylated metabolites be used as marker residues of EPTC residues of toxicological concern. Therefore, in order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to redesignate the existing paragraph from 40 CFR 180.117 to 180.117(a) and revise the introductory text containing the tolerance expression in newly designated 40 CFR 180.117(a) to include its hydroxylated metabolites as marker residues of S-ethyl dipropylthiocarbamate residues of toxicological concern (i.e., markers of EPTC, EPTC sulfoxide, EPTC sulfone, and the EPTC conjugates resulting from the glutathione-S-transferase pathway), to read as follows:

Tolerances are established for residues of the herbicide S-ethyl dipropylthiocarbamate, including its metabolites and degradates, in or on the commodities in the table in this paragraph. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of S-ethyl dipropylthiocarbamate, S-ethyl (2- hydroxypropyl)propylcarbamothioate, S-(2- hydroxyethyl)dipropylcarbamothioate, and S-ethyl (3- hydroxypropyl)propylcarbamothioate, calculated as the stoichiometric equivalent of S-ethyl dipropylthiocarbamate, in or on the commodity.

The majority of the current crop groupings for residues of EPTC are based on obsolete crop groupings and, for many, the minimum data requirements for the establishment of crop group tolerances were not satisfied. Therefore, in the EPTC RED, the Agency recommended revocation of crop group tolerances, concomitant with the establishment of individual tolerances for the affected commodities.

Based on available field trial data that showed residues of S-ethyl dipropylthiocarbamate and its hydroxylated metabolites were 5 ppm. Also, given that a proposed food handling establishment tolerance of 5 ppm in 40 CFR 180.367(a)(2) would cover the individual fat tolerances for residues resulting from dermal application at 0.3 ppm in Sec. 180.367(a)(1), the Agency determined that there is no longer a need for the fat tolerances at 0.3 ppm and they should be revoked. In addition, because tolerances for residues in or on food from applications in food-processing and food-storage areas currently exist in 40 CFR 180.127(a)(2)(iii) for piperonyl butoxide at 10 ppm and in 40 CFR 180.128(a)(3) for pyrethrins at 1.0 ppm, the

Agency determined that the tolerances for piperonyl butoxide and pyrethrins in 40 CFR 180.367(a)(2) are duplicates which are no longer needed and should be revoked since the use would be covered by the other tolerances. Therefore, EPA is proposing to revoke the tolerances at 0.3 ppm in 40 CFR 180.367(a)(1) for N-octyl bicycloheptene dicarboximide residues resulting from dermal application in or on cattle, fat; goat, fat; hog, fat; horse, fat; milk, fat; and sheep, fat; and remove existing paragraph (a)(1) in its entirety, revoke the tolerances for piperonyl butoxide at 10 ppm and pyrethrins at 1 ppm in 40 CFR 180.367(a)(2)(ii), remove existing introductory text in 40 CFR 180.367(a)(2), (a)(2)(i), and (a)(2)(iii); decrease the tolerance in 40

CFR 180.367(a)(2)(ii) to 5 ppm and redesignate it as 40 CFR 180.367(a), and revise newly designated paragraph (a), as follows:

A tolerance of 5 parts per million is established for residues of the insecticide synergist N-octyl bicycloheptene dicarboximide, including its metabolites and degradates, in or on all food items in food handling establishments where food and food products are held, processed, prepared and/or served, provided that the food is removed or covered prior to such use, except for bagged food in warehouse storage which need not be removed or covered prior to applications of formulations containing N-octyl bicycloheptene dicarboximide.

Compliance with the tolerance level specified in this paragraph is to be determined by measuring only N-octyl bicycloheptene dicarboximide, in or on the commodity.

Because there have been no uses of N-octyl bicycloheptenedicarboximide, MGK-264, in or on growing agricultural crops for more than 10 years, the tolerance exemption is no longer needed and therefore should be revoked. Consequently, EPA is proposing to revoke the tolerance exemption in 40 CFR 180.905(a)(2) for N-octyl bicyclo(2,2,1)-5-heptene-2,3-dicarboximide, when applied to growing crops. In addition, EPA is proposing to revise 40 CFR 180.905(a) as described herein under proposals for pyrethrum.

There are no Codex MRLs for N-octyl bicycloheptene dicarboximide. 16. Phosmet. On November 4, 2005, EPA published a notice in the

Federal Register (70 FR 67167) (FRL-7744-7) that announced the Agency's receipt of requests from the registrants for amendments to delete uses in certain pesticide registrations, including the last phosmet uses on cotton. No comments were received by EPA and the Agency approved the use deletions on December 5, 2005, and permitted the registrants to sell and distribute existing stocks for a period of 18 months after approval; i.e., until June 5, 2007. The Agency believes that end users have had sufficient time to exhaust those existing stocks and for treated cotton to have cleared the channels of trade. Therefore, EPA is proposing to revoke the tolerances in 40 CFR 180.261(a) on cotton, refined oil and cotton, undelinted seed.

Also, in order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the section heading in 40 CFR 180.261 from N-(mercaptomethyl) phthalimide S-(O,O- dimethyl phosphorodithioate) and its oxygen analog to phosmet and revise the introductory text containing the tolerance expression in 40

CFR 180.261(a) to read as follows:

Tolerances are established for residues of the insecticide phosmet, N-(mercaptomethyl) phthalimide S-(O,O-dimethyl phosphorodithioate), including its metabolites and degradates, in or on the commodities in the table in this paragraph. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of phosmet, N-(mercaptomethyl) phthalimide

S-(O,O-dimethyl phosphorodithioate), and its oxygen analog, N-

(mercaptomethyl) phthalimide S-(O,O-dimethyl phosphorothioate, calculated as the stoichiometric equivalent of phosmet, in or on the commodity.

In addition, EPA is proposing to revise the introductory text containing the tolerance expression for regional tolerances in 40 CFR 180.261(c) to read as follows:

Tolerances with regional registration are established for residues of the insecticide phosmet, N-(mercaptomethyl) phthalimide

S-(O,O-dimethyl phosphorodithioate), including its metabolites and degradates, in or on the commodities in the table in this paragraph.

Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of phosmet, N-

(mercaptomethyl) phthalimide S-(O,O-dimethyl phosphorodithioate), and its oxygen analog, N-(mercaptomethyl) phthalimide S-(O,O- dimethyl phosphorothioate, calculated as the stoichiometric equivalent of phosmet, in or on the commodity.

Page 28168

There are Codex MRLs on certain commodities for phosmet, including an MRL on cottonseed. 17. Picloram. As a post-RED action, EPA made certain tolerance determinations for picloram on November 19, 2009 in a document made available in the public docket of this proposed rule. Because there is no need for a different tolerance expression for the existing tolerances for picloram residues in processed grain commodities in 40

CFR 180.292(a)(2), EPA determined that paragraph (a)(2) should be removed and the tolerances there should be moved into the table in

Sec. 180.292(a)(1), which therefore should be redesignated as paragraph (a).

Also, in order to describe more clearly the measurement and scope or coverage of the tolerances, EPA is proposing to revise the introductory text containing the tolerance expression in newly designated 40 CFR 180.292(a) to read as follows:

Tolerances are established for residues of the herbicide picloram, 4-amino-3,5,6-trichloropicolinic acid, including its metabolites and degradates, in or on the commodities in the table in this paragraph from its application in the acid form or in the form of its salts. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only picloram, 4-amino- 3,5,6-trichloropicolinic acid, in or on the commodity.

Based on available field trial data that showed picloram residues of 195 ppm in or on grass forage at an application rate of 0.5 lb ae/A with a 0-day PHI, EPA determined that the existing tolerance should be increased from 80.0 to 400 ppm, which is an appropriate tolerance level for grass forage for the existing maximum approved rate of 1.0 lb ae/A.

Also, based on available data that showed picloram residues as high as 170 ppm in or on grass hay at an application rate of 2.0 lb ae/A with a 14-day PHI and 213 ppm in or on grass hay at an application rate of 0.5 lb ae/A with a 0-day PHI, EPA determined that a tolerance should be established on grass hay at 225 ppm. Therefore, EPA is proposing to increase the tolerance in 40 CFR 180.292(a) on grass, forage to 400 ppm and establish a tolerance in 40 CFR 180.292(a) on grass, hay at 225 ppm. The Agency determined that the increased tolerance is safe; i.e., there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue.

Based on available cattle exaggerated feeding data at 1.39X the

Maximum Theoretical Dietary Burden (MTDB) that showed picloram residues at 0.5 ppm in fat, 0.5 ppm in muscle, 18 ppm in kidney, 2.0 ppm in liver, and 0.29 ppm in milk, EPA calculated that the maximum expected residues in fat, muscle, meat byproducts, and milk at 1X MTDB to be 0.36 ppm, 0.36 ppm, 12.95 ppm, and 0.21 pm, respectively. Therefore, the Agency determined that the tolerances for the fat and meat of cattle, goats, horses, and sheep should be increased from 0.2 to 0.4 ppm, the tolerance for milk should be increased from 0.05 to 0.25 ppm; the separate tolerances for the kidney of cattle, goats, horses, and sheep, and liver of cattle, goats, horses, and sheep should be revoked because they will be covered by redefined meat byproduct tolerances for cattle, goats, horses, and sheep, and the redefined meat byproduct tolerances should be increased to 15 ppm. Consequently, EPA is proposing to increase the tolerances in 40 CFR 180.292(a) on cattle, fat; cattle, meat; goat, fat; goat, meat; horse, fat; horse, meat; sheep, fat; and sheep, meat to 0.4 ppm, and milk to 0.25 ppm. Also, EPA is proposing to revoke the individual tolerances in 40 CFR 180.292(a) on cattle, kidney; cattle, liver; goat, kidney; goat, liver; horse, kidney, horse, liver; sheep kidney; and sheep, liver. In addition, EPA is proposing to revise the tolerances in 40 CFR 180.292(a) on ``cattle, meat byproducts, except kidney and liver'' to ``cattle, meat byproducts;'' ``goat, meat byproducts, except kidney and liver'' to

``goat, meat byproducts;'' ``horse, meat byproducts, except kidney and liver'' to ``horse, meat byproducts;'' and ``sheep, meat byproducts, except kidney and liver'' to ``sheep, meat byproducts;'' and increase them to 15 ppm. The Agency determined that the increased tolerances are safe; i.e., there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue.

Although grass commodities are not significant feed items for swine, wheat milled byproduct feed items which have picloram tolerances show that the MTDB for swine is low (1.5 ppm). The lowest levels of picloram fed to cattle and sheep (200 and 30 ppm) were well above the anticipated exposure for hogs and the 30 ppm dose showed picloram residues in kidney, liver, fat, and muscle of sheep were 0.38 ppm,
