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. 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 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 certain tolerances, proposing some with
expiration dates, for the insecticides chlorpyrifos, endosulfan,
methidathion, methyl parathion, and ethyl parathion, the fungicide
chloroneb, and the plant growth regulators clofencet and N,N-diethyl-2-
(4-methylbenzyloxy)ethylamine hydrochloride. Also, EPA is proposing to
modify certain tolerances for the herbicide atrazine. In addition, EPA
is proposing to establish new tolerances with expiration/revocation
dates for the insecticide endosulfan. Moreover, in accordance with
current Agency practice to describe more clearly the measurement and
scope or coverage of the tolerances, including applicable metabolites
and degradates, EPA is proposing minor revisions to tolerance
expressions for a number of pesticide active ingredients, including the
insecticides endosulfan, methidathion, and methyl parathion, the
fungicide chloroneb, and the plant growth regulator clofencet. The
revisions do not substantively change the tolerance or, in any way,
modify the permissible level of residues permitted by the tolerance. In
addition, EPA will be removing currently expired tolerances for
methidathion, methyl parathion, and ethyl parathion.
    EPA is proposing these tolerance actions to follow-up on canceled
uses of chloroneb, chlorpyrifos, clofencet, N,N-diethyl-2-(4-
methylbenzyloxy)ethylamine hydrochloride, endosulfan, ethyl parathion,
methidathion, and methyl parathion, and modify certain tolerances as
recommended in the atrazine Reregistration Eligibility Decision (RED)
of 2006. As part of the tolerance reassessment process, 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 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<PHONE_NUMBER>; Internet at http://www.ntis.gov. An electronic copy is available on the Internet for the
atrazine interim RED in docket EPA-HQ-OPP-2003-0072 at http://www.regulations.gov and for the atrazine final RED 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:
    1. Lawful use (sometimes through a label change) may result in a
higher residue level on the commodity.
    2. 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
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 an electronic copy for atrazine is available in the public
docket for this proposed rule. Electronic copies are available through
EPA's electronic 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-2011-0104, 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 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
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
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.
    Certain tolerances pertaining to the pesticides subject to this
proposal have expired due to previous EPA regulation setting expiration
dates. When the Agency finalizes the changes proposed in this document,
EPA will also remove the expired tolerances from the Code of Federal
Regulations. The amended regulatory text below reflects removal of the
tolerances. The Agency is not accepting comments regarding the expired
tolerances.
    1. Atrazine. Based on available field trial data that showed
combined atrazine residues of concern as high as 1.1 ppm in or on field
corn forage harvested 60 days after treatment and product labels that
show a pre-harvest interval (PHI) of 60 days for field corn forage, the
Agency determined that the tolerance on corn, field, forage should be
decreased from 15 to 1.5 ppm. Therefore, EPA is proposing in 40 CFR
180.220(a) to decrease the tolerance on corn, field, forage to 1.5 ppm.
    Also, based on available field trial data that showed combined
atrazine residues of concern as high as 0.18 ppm in or on sorghum
forage harvested 60 days after a single pre-emergence 1X application
and <0.1 ppm in or on sorghum forage harvested 45 days after a 0.25X
pre-emergence application followed by one post-emergence 1X application
(the maximum use pattern), and product labels that show PHIs of 60 and
45 days for pre-emergence and post-emergence treatment of sorghum
forage, respectively, the Agency determined that the tolerances on
sorghum, forage, forage and sorghum, grain forage should each be
decreased from 15 to 0.25 ppm, and sorghum, grain forage revised to
sorghum, grain, forage. Therefore, EPA is proposing in 40 CFR
180.220(a) to decrease the tolerance on sorghum, forage, forage to 0.25
ppm and decrease the tolerance on sorghum, grain forage to 0.25 ppm and
revise it to sorghum, grain, forage.
    2. Chloroneb. In the Federal Register notice of May 25, 2007 (72 FR
29315) (FRL-8121-6), EPA published a notice of receipt of requests to
voluntarily cancel certain uses, including uses of chloroneb as a seed
treatment on beans, cowpeas, cotton, lupine, soybeans, and sugarbeets.
In the Federal Register notice of November 7, 2007 (72 FR 62847) (FRL-
8154-7), EPA approved cancellation of the affected product
registrations and permitted the registrant to sell and distribute
existing stocks of the affected products containing chloroneb for one
year after the date of the request; i.e., until February 7, 2008.
Persons other than registrant are permitted to sell, distribute, and/or
use existing stocks of canceled chloroneb products until they are
exhausted, provided that the use complies with the EPA approved label
and labeling of the affected products. In the Federal Register notice
of April 16, 2008 (73 FR 20642) (FRL-8358-5), EPA published a notice of
receipt of requests to voluntarily cancel certain registrations,
including uses of chloroneb as a seed treatment on beans and cotton,
the last uses of chloroneb as seed treatments in the United States. On
October 14, 2008, EPA approved cancellation of the last seed treatment
product registrations for use of chloroneb. The registrant is permitted
to sell and distribute existing stocks of the

affected products containing chloroneb for one year after the date of
the request; i.e., until April 16, 2009. Persons other than registrant
are permitted to sell, distribute, and/or use existing stocks of
canceled chloroneb products until they are exhausted, provided that the
use complies with the EPA approved label and labeling of the affected
product.
    EPA believes that existing stocks are likely to be exhausted by
April 16, 2012. Therefore, EPA is proposing to revoke the tolerances
for chloroneb in 40 CFR 180.257(a) on bean, dry, seed; bean, succulent;
beet, sugar, roots; beet, sugar, tops; cowpea, forage; cowpea, hay;
cattle, fat; cattle, meat; cattle, meat byproducts; cotton, gin
byproducts; cotton, undelinted seed; goat, fat; goat, meat; goat, meat
byproducts; hog, fat; hog, meat; hog, meat byproducts; horse, fat;
horse, meat; horse, meat byproducts; milk; sheep, fat; sheep, meat;
sheep, meat byproducts; soybean, forage; soybean, hay; and soybean,
seed; each with an expiration/revocation date of April 16, 2012.
    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 180.257(a) to read
as follows:
    Tolerances are established for residues of the fungicide chloroneb,
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 chloroneb, 1,4-dichloro-2,5-dimethoxybenzene, and its metabolite
2,5-dichloro-4-methoxyphenol (free and conjugated), calculated as the
stoichiometric equivalent of chloroneb, in or on the commodity.
    3. Chlorpyrifos. There are no active registrations, and there have
been none, for use of chlorpyrifos in or on lettuce in the United
States. EPA established in 40 CFR 180.342 the lettuce tolerance for
chlorpyrifos on September 17, 2008 (73 FR 53732) (FRL-8375-2). However,
while the chlorpyrifos IRED of 2001 and RED of 2006 recommended a
tolerance on lettuce, noting petition 4F3132 which had been submitted
on July 31, 1984, the registrant had withdrawn the petition on July 24,
2006. Therefore, the lettuce tolerance is no longer needed and should
be revoked. Consequently, EPA is proposing to revoke the tolerance in
40 CFR 180.342(a)(1) on lettuce.
    4. Clofencet. In accordance with current Agency practice, EPA is
proposing to revise 40 CFR 180.497 by redesignating currently existing
paragraph (b) as paragraph (d) for indirect or inadvertent residues,
adding and reserving new paragraph (b) for tolerances with section 18
emergency exemptions, and adding and reserving new paragraph (c) for
tolerances with regional registrations.
    In the Federal Register of April 28, 2010 (75 FR 22404) (FRL-8822-
1), EPA published a notice of receipt of requests to voluntarily cancel
all pesticide registrations containing clofencet. In the Federal
Register notice of July 14, 2010 (75 FR 40825) (FRL-8833-4), EPA
approved cancellation of the last FIFRA product registrations for use
of clofencet in the United States. The registrant is permitted to sell
and distribute existing stocks of the affected products containing
clofencet until July 14, 2011. Persons other than the registrant are
permitted to sell, distribute, and/or use existing stocks of canceled
clofencet products until they are exhausted, provided that the use
complies with the EPA approved label and labeling of the affected
products. However, the registrant believes that there is little or no
product in the channels of trade. Therefore, EPA is proposing to revoke
the tolerances in 40 CFR 180.497(a) on cattle, fat; cattle, kidney;
cattle, meat; cattle, meat byproducts, except kidney; egg; goat, fat;
goat, kidney; goat, meat; goat, meat byproducts, except kidney; hog,
fat; hog, kidney; hog, meat; hog, meat byproducts, except kidney;
horse, fat; horse, kidney; horse, meat; horse, meat byproducts, except
kidney; milk; poultry, fat; poultry, meat; poultry, meat byproducts;
sheep, fat; sheep, kidney; sheep, meat; sheep, meat byproducts, except
kidney; wheat, forage; wheat, grain; wheat, hay; and wheat, straw; each
with an expiration/revocation date of July 14, 2012, and tolerances for
indirect or inadvertent residues in newly designated 40 CFR 180.497(d)
on grain, cereal, forage, fodder and straw, group 16, except rice,
sweet corn, wheat, and wild rice; forage; grain, cereal, forage, fodder
and straw, group 16, except rice, sweet corn, wheat, and wild rice;
hay; grain, cereal, forage, fodder and straw, group 16, except rice,
sweet corn, wheat, and wild rice; stover; grain, cereal, forage, fodder
and straw, group 16, except rice, sweet corn, wheat, and wild rice;
straw; grain, cereal group 15, except rice, sweet corn, wheat, and wild
rice; soybean; soybean, forage; and soybean, hay; each with an
expiration/revocation date of July 14, 2012.
    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 180.497(a) to read
as follows:
    Tolerances are established for residues of the plant growth
regulator (hybridizing agent) clofencet, 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 clofencet, potassium 2-(4-
chlorophenyl)-3-ethyl-2,5-dihydro-5-oxo-4-pyridazinecarboxylate,
expressed as the free acid, in or on the commodity.
    Also, EPA is proposing to revise the introductory text containing
the tolerance expression in newly designated 40 CFR 180.497(d) to read
as follows:
    Tolerances are established for indirect or inadvertent residues of
the plant growth regulator (hybridizing agent) clofencet, 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 clofencet, potassium 2-
(4-chlorophenyl)-3-ethyl-2,5-dihydro-5-oxo-4-pyridazinecarboxylate,
expressed as the free acid, in or on the commodity when present therein
as a result of the application of clofencet to the growing crops in
paragraph (a) of this section.
    5. N,N-Diethyl-2-(4-methylbenzyloxy)ethylamine hydrochloride.
Because there have been no active registrations for N,N-diethyl-2-(4-
methylbenzyloxy)ethylamine hydrochloride in the United States since
2004, the sole existing tolerance, which is on orange, sweet, is no
longer needed and should be revoked. Therefore, EPA is proposing to
revoke the tolerance in 40 CFR 180.558(a) on orange, sweet and remove
that section in its entirety.
    6. Endosulfan. There have been no active registrations for use of
endosulfan in the United States for rapeseed and watercress since
October 2004; sugarcane since July 2005; grapes, succulent peas,
pecans, and spinach since December 2005; barley, oats, rye, and wheat
since October 2007. There are no active registrations for use of
endosulfan in the United States for growing tea and there may never
have been one. Therefore, these tolerances are no longer needed and
should be revoked. Consequently, EPA is proposing to revoke the sole
tolerance in 40 CFR 180.182(a)(2) on dried tea (24 ppm in or on dried
tea, reflecting less than 0.1 ppm in beverage tea), remove paragraph
(a)(2) in its entirety, and redesignate 40 CFR 180.182(a)(1) as (a). In
addition, EPA is proposing to revoke the tolerances in newly designated
40 CFR 180.182(a) on barley, grain; barley, straw; grape; oat, grain;
oat, straw; pea, succulent; pecan; rapeseed, seed; rye,

grain; rye, straw; spinach; sugarcane, cane; watercress; wheat, grain;
and wheat, straw.
    In a Memorandum of Agreement (MOA) between the endosulfan
registrants and the Agency, made effective July 22, 2010, terms
regarding registrant requests for voluntary cancellation of all
existing FIFRA registrations for endosulfan were specified. In the
Federal Register notice of November 10, 2010 (75 FR 69065) (FRL-8852-
4), EPA approved cancellation of the last FIFRA section 24 and section
3 registrations, respectively, for use of endosulfan in the United
States. The List 1 (Phase-Out Group A, which includes almond, apricot,
carrots, dry beans, tart cherry, eggplant, filbert, also known as
hazelnut, macadamia nut, plum, prune, sweet potato, and walnut) uses of
existing stocks of the end-use products, for endosulfan, are prohibited
after July 31, 2012, except for products intended for export consistent
with the requirements of section 17 of FIFRA or proper disposal. (The
MOA and FR notices are available electronically under docket ID number
EPA-HQ-OPP-2002-0262). Therefore, EPA is proposing to revoke the
tolerances for endosulfan in newly designated 40 CFR 180.182(a) on
almond; almond hulls; apricot; bean; carrot, roots; cherry, tart;
eggplant; hazelnut; nut, macadamia; plum; plum, prune; sweet potato,
roots; and walnut; each with an expiration/revocation date of July 31,
2012.
    The List 2 (Phase-Out Group B, which includes cabbage, celery (AZ
only), cotton, lettuce, nectarine (non-CA), peach, and sweet cherry)
uses of existing stocks of the end-use products, for endosulfan, are
prohibited after July 31, 2012, except for products intended for export
consistent with the requirements of section 17 of FIFRA or proper
disposal. It should be noted that celery (non-AZ) and nectarine (CA
only) uses are included in List 1. Therefore, EPA is proposing to
revoke the tolerance for endosulfan in newly designated 40 CFR
180.182(a) on cabbage; celery; cherry, sweet; cotton, gin byproducts;
cotton, undelinted seed; lettuce, head; lettuce, leaf; nectarine; and
peach; each with an expiration/revocation date of July 31, 2012.
    The List 3 (Phase-Out Group C, which includes pear) use of existing
stocks of the end-use products, for endosulfan, are prohibited after
July 31, 2013, except for products intended for export consistent with
the requirements of section 17 of FIFRA or proper disposal. Therefore,
EPA is proposing to revoke the tolerance for endosulfan in newly
designated 40 CFR 180.182(a) on pear with an expiration/revocation date
of July 31, 2013.
    The List 4 (Phase-Out Group D, which includes apple, blueberry,
pepper, potato, pumpkin, sweet corn, tomato, and winter squash) uses of
existing stocks of the end-use products, for endosulfan, in the state
of Florida are prohibited after December 31, 2014, except for products
intended for export consistent with the requirements of section 17 of
FIFRA or proper disposal. The List 5 (Phase-Out Group E which includes
apple, blueberry, pepper, potato, pumpkin, sweet corn, tomato, and
winter squash) uses of existing stocks of the end-use products, for
endosulfan, in the United States (except Florida) are prohibited after
July 31, 2015, except for products intended for export consistent with
the requirements of section 17 of FIFRA or proper disposal. Endosulfan
uses on pumpkin and winter squash (members of vegetable, cucurbit,
group 9) are included in Phase-Out Groups D and E. Therefore, EPA is
proposing to revoke the tolerances for endosulfan in newly designated
40 CFR 180.182(a) on apple; apple, wet pomace; blueberry; corn, sweet,
forage; corn, sweet, kernel plus cob with husks removed; corn, sweet,
stover; pepper; potato; tomato; and vegetable, cucurbit, group 9; and
concomitantly revise 40 CFR 180.182(c) and establish tolerances on
apple at 1.0 ppm; apple, wet pomace at 5.0 ppm; blueberry at 0.3 ppm;
corn, sweet, forage at 12.0 ppm; corn, sweet, kernel plus cob with
husks removed at 0.2 ppm; corn, sweet, stover at 14.0 ppm; pepper at
2.0 ppm; potato at 0.2 ppm; pumpkin at 1.0 ppm; squash, winter at 1.0
ppm; and tomato at 1.0 ppm in newly designated 40 CFR 180.182(c)(1) for
regional tolerances for use in the state of Florida, each with an
expiration date of December 31, 2014, and establish tolerances on apple
at 1.0 ppm; apple, wet pomace at 5.0 ppm; blueberry at 0.3 ppm; corn,
sweet, forage at 12.0 ppm; corn, sweet, kernel plus cob with husks
removed at 0.2 ppm; corn, sweet, stover at 14.0 ppm; pepper at 2.0 ppm;
potato at 0.2 ppm; pumpkin at 1.0 ppm; squash, winter at 1.0 ppm; and
tomato at 1.0 ppm in newly designated 180.182(c)(2) for regional
tolerances for use in the United States (except Florida), each with an
expiration date of July 31, 2015. In addition, because EPA is proposing
to revoke the tolerance on vegetable, cucurbit, group 9 at 1.0 ppm in
newly designated 40 CFR 180.182(a) and (Phase-Out Group B) uses on
cantaloupe, cucumber, honeydew (muskmelon), summer squash, and
watermelon are allowed until July 31, 2012, EPA is also proposing to
establish individual tolerances at 1.0 ppm in newly designated 40 CFR
180.182(a) for cantaloupe; cucumber; muskmelon; squash, summer; and
watermelon; each with an expiration/revocation date of July, 31, 2012.
    The List 6 (Phase-Out Group F, which includes certain specific
vegetable crops for seed) uses of existing stocks of the end-use
products, for endosulfan, are prohibited after July 31, 2016, except
for products intended for export consistent with the requirements of
section 17 of FIFRA or proper disposal. Therefore, uses of endosulfan
in or on vegetables grown for seed, including alfalfa, broccoli,
Brussels sprouts, cabbage, cauliflower, collards, kale, kohlrabi,
mustard greens, radishes, rutabagas, and turnips are prohibited after
July 31, 2016. Following examination of product labels, the Agency
classified these endosulfan seed treatment uses as non-food (see
``Endosulfan: The Health Effects Division's REVISED Human Health Risk
Assessment'' in public docket EPA-HQ-OPP-2002-0262), and therefore
these uses do not need to be covered by a tolerance. Because there are
only active registrations in the United States for use of endosulfan in
or on both alfalfa and turnip grown for seed crop, EPA is proposing to
revoke the tolerances in newly designated 40 CFR 180.182(a) on alfalfa,
forage; alfalfa, hay; turnip, roots; and turnip, tops at the time of
publication of the final rule in the Federal Register. However, (within
Phase-Out Group A) foliar treatment uses of endosulfan for broccoli,
Brussels sprouts, cauliflower, collards, kale, and mustard greens are
allowed until July 31, 2012. Consequently, EPA is proposing to revoke
the tolerances in newly designated 40 CFR 180.182(a) on broccoli;
Brussels sprouts; cauliflower; collards; kale; mustard greens; and
mustard, seed; each with an expiration date of July 31, 2012.
    Other List 6 (Phase-Out Group F, which includes livestock ear tags,
strawberry (perennial/biennial), and pineapple) uses of existing stocks
of the end-use products for endosulfan are prohibited after July 31,
2016, except for products intended for export consistent with the
requirements of section 17 of FIFRA or proper disposal. (It should be
noted that strawberry (annual) use is included in List1). Therefore,
EPA is proposing to revoke the tolerances for endosulfan in newly
designated 40 CFR 180.182(a) on cattle, fat; cattle, liver; cattle,
meat; cattle, meat byproducts, except liver; goat, fat; goat, liver;
goat, meat; goat, meat byproducts, except liver; hog, fat; hog, liver;
hog, meat; hog,

meat byproducts, except liver; horse, fat; horse, liver; horse, meat;
horse, meat byproducts, except liver; milk, fat; pineapple; pineapple,
process residue; sheep, fat; sheep, liver; sheep, meat; sheep, meat
byproducts, except liver; and strawberry; each with an expiration/
revocation date of July 31, 2016.
    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
180.182(a) to read as follows:
    Tolerances are established for residues of the insecticide
endosulfan, 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 endosulfan, 6,7,8,9,10,10-hexachloro-
1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepin 3-oxide
(alpha and beta isomers), and its metabolite endosulfan sulfate,
6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-
benzodioxathiepin-3,3-dioxide, calculated as the stoichiometric
equivalent of endosulfan, in or on the commodity.
    Also, EPA is proposing to revise the introductory text containing
the tolerance expression in newly designated 40 CFR 180.182(c)(1) to
read as follows:
    Tolerances with regional registration, as defined in Sec.
180.1(l), are established for residues of the insecticide endosulfan,
including its metabolites and degradates, in or on the commodities in
the table in this paragraph, when endosulfan is used in the state of
Florida. Compliance with the tolerance levels specified in this
paragraph is to be determined by measuring only the sum of endosulfan,
6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-
benzodioxathiepin 3-oxide (alpha and beta isomers), and its metabolite
endosulfan sulfate, 6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-
6,9-methano-2,4,3-benzodioxathiepin-3,3-dioxide, calculated as the
stoichiometric equivalent of endosulfan, in or on the commodity.
    In addition, EPA is proposing to revise the introductory text
containing the tolerance expression in newly designated 40 CFR
180.182(c)(2) to read as follows:
    Tolerances with regional registration, as defined in Sec.
180.1(l), are established for residues of the insecticide endosulfan,
including its metabolites and degradates, in or on the commodities in
the table in this paragraph, when endosulfan is used in the United
States (except Florida). Compliance with the tolerance levels specified
in this paragraph is to be determined by measuring only the sum of
endosulfan, 6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-
methano-2,4,3-benzodioxathiepin 3-oxide (alpha and beta isomers), and
its metabolite endosulfan sulfate, 6,7,8,9,10,10-hexachloro-
1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepin-3,3-
dioxide, calculated as the stoichiometric equivalent of endosulfan, in
or on the commodity.
    7. Methidathion. After the Final Work Plan was published in August
2009 as part of the registration review process for methidathion, the
registrants requested to voluntarily cancel all of their methidathion
product registrations. In the Federal Register of April 7, 2010 (75 FR
17735) (FRL-8819-1), EPA published a notice of receipt of requests to
voluntarily cancel all pesticide registrations containing methidathion.
In the Federal Register notice of June 2, 2010 (75 FR 30824) (FRL-8828-
4), EPA approved cancellation of the last FIFRA product registrations
for use of methidathion in the United States. After December 31, 2012,
registrants are prohibited from selling or distributing existing stocks
of products containing methidathion labeled for all uses. After
December 31, 2014, persons other than registrants are prohibited from
selling or distributing existing stocks of products containing
methidathion labeled for all uses. The cancellation order of June 2,
2010 (75 FR 30824) also stated that after December 31, 2014, existing
stocks of products containing methidathion labeled for all uses,
already in the hands of users can be used legally until they are
exhausted, provided that the use complies with the EPA approved label
and labeling of the affected product. However, based on communications
with the registrants since the cancellation, EPA believes that existing
stocks are likely to be exhausted by December 31, 2016. Therefore, EPA
is proposing to revoke the tolerances in 40 CFR 180.298(a) on almond,
hulls; artichoke, globe; citrus, oil; cotton, undelinted seed; fruit,
citrus, group 10, except tangerine; fruit, pome, group 11; fruit,
stone, group 12; mango; nut, tree, group 14; olive; safflower, seed;
sorghum, forage, forage; sorghum, grain, forage; sorghum, grain, grain;
sorghum, grain, stover; sunflower, seed; and tangerine; each with an
expiration/revocation date of December 31, 2016, and regional
tolerances in 180.298(c) on kiwifruit; longan; starfruit; and sugar
apple; each with an expiration/revocation date of December 31, 2016.
    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 180.298(a) to read
as follows:
    Tolerances are established for residues of the insecticide
methidathion, 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 methidathion, S-[(5-methoxy-2-oxo-1,3,4-thiadiazol-
3(2H)-yl)methyl] O,O-dimethyl phosphorodithioate, in or on the
commodity.
    Also, EPA is proposing to revise the introductory text containing
the tolerance expression in 40 CFR 180.298(c) to read as follows:
    Tolerances with regional registration, as defined in Sec.
180.1(l), are established for residues of the insecticide methidathion,
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
methidathion, S-[(5-methoxy-2-oxo-1,3,4-thiadiazol-3(2H)-yl)methyl]
O,O-dimethyl phosphorodithioate, in or on the commodity.
    In addition, EPA is removing tolerances that expired in 2008 for
methidathion in 40 CFR 180.298(c).
    8. Methyl parathion and ethyl parathion. In March 2010, EPA and the
methyl parathion registrants signed a Memorandum of Agreement (MOA)
stating that all methyl parathion product registrations would be
canceled as specified therein. In the Federal Register notice of April
28, 2010 (75 FR 22402) (FRL-8822-6), EPA published a notice of receipt
of requests to voluntarily cancel specific methyl parathion
registrations, which included the last registrations for use of methyl
parathion in or on alfalfa, almonds, barley, corn, cotton, grasses,
oats, onions, peas, potatoes, rapeseed, rice, rye, soybeans,
sunflowers, and wheat in the United States. In the Federal Register
notices of November 10, 2010 (75 FR 69073) (FRL-8851-5) and January 26,
2011 (76 FR 4692) (FRL-8856-9), EPA published notices of receipt of
requests to voluntarily cancel specific methyl parathion registrations,
which included the last registrations for

use of methyl parathion in or on sweet potatoes and walnuts in the
United States. In the Federal Register notice of July 27, 2010 (75 FR
43981) (FRL-8838-6), EPA approved the cancellations and permitted use
of existing stocks of the end-use products for methyl parathion in or
on alfalfa, almonds, barley, corn, cotton, grasses, oats, onions, peas,
potatoes, rapeseed, rice, rye, soybeans, sunflowers, and wheat through
December 31, 2013. Also, in the Federal Register notices of February
25, 2011 (76 FR 10587) (FRL-8863-4) and March 23, 2011 (76 FR 16417)
(FRL-8867-8), EPA approved the cancellations and permitted use of
existing stocks of the end-use products for methyl parathion in or on
sweet potatoes and walnuts until exhausted, provided use is consistent
with the terms of the previously approved labeling on, or that
accompanied, the canceled products. In accordance with the MOA, all use
of existing stocks of the end-use products for methyl parathion,
including in or on sweet potatoes and walnuts, are permitted through
December 31, 2013, but not thereafter. (The MOA and FR notices are
available electronically under docket ID numbers EPA-HQ-OPP-2009-0332
and EPA-HQ-OPP-2009-1017). Therefore, EPA is proposing to revoke the
tolerances for methyl parathion in 40 CFR 180.121(a) on alfalfa,
forage; alfalfa, hay; almond; almond, hulls; barley; corn, field,
forage; corn, field, grain; corn, pop, grain; corn, sweet, forage;
corn, sweet, kernel plus cob with husks removed; cotton, undelinted
seed; grass, forage; oat; onion; pea, field, vines; potato; rapeseed,
seed; rice, grain; soybean, hay; soybean, seed; sunflower, seed; sweet
potato, roots; walnut; and wheat; each with an expiration date of
December 31, 2013. Also, because there have been no active
registrations in the United States for use of ethyl parathion in or on
rye since 1989, the interim tolerance on rye in 40 CFR 180.319 for
``Parathion (O,O-diethyl-O-p-nitrophenythiophosphate) or its methyl
homolog'' should be separated into interim tolerances on rye for ethyl
parathion and methyl parathion to allow an expiration/revocation date
for methyl parathion and revocation for ethyl parathion on the date of
publication of the final rule in the Federal Register. Therefore, EPA
is proposing to separate the existing interim tolerance for parathion
on rye in 40 CFR 180.319 into one for methyl parathion and another for
ethyl parathion, revoke the newly designated interim tolerance for
methyl parathion on rye with an expiration/revocation date of December
31, 2013, and revoke the newly designated interim tolerance on rye for
ethyl parathion on the date of publication of the final rule in the
Federal Register. Also, because all the tolerances for ethyl parathion
in 40 CFR 180.122 expired in 2005, EPA will remove that section in its
entirety. In addition, because there have been no active registrations
for methyl parathion use on peanuts since 1998, EPA is proposing to
revoke the tolerance in 40 CFR 180.121(a) on peanut on the date of
publication of the final rule in the Federal Register. Moreover, EPA is
removing tolerances that expired in 2009 for methyl parathion in 40 CFR
180.121(a).
    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 180.121(a) to read
as follows:
    Tolerances are established for residues of the insecticide methyl
parathion, 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 methyl parathion, O,O-dimethyl O-(4-nitrophenyl)
phosphorothioate, in or on the commodity.

B. What is the agency's authority for taking this action?

    A ``tolerance'' represents the maximum level for residues of
pesticide chemicals legally allowed in or on raw agricultural
commodities and processed foods. Section 408 of FFDCA, 21 U.S.C. 346a,
as amended by FQPA of 1996, Public Law 104-170, authorizes the
establishment of tolerances, exemptions from tolerance requirements,
modifications in tolerances, and revocation of tolerances for residues
of pesticide chemicals in or on raw agricultural commodities and
processed foods. Without a tolerance or exemption, food containing
pesticide residues is considered to be unsafe and therefore
``adulterated'' under section 402(a) of FFDCA, 21 U.S.C. 342(a). Such
food may not be distributed in interstate commerce (21 U.S.C. 331(a)).
For a food-use pesticide to be sold and distributed, the pesticide must
not only have appropriate tolerances under the FFDCA, but also must be
registered under FIFRA (7 U.S.C. 136 et seq.). Food-use pesticides not
registered in the United States must have tolerances in order for
commodities treated with those pesticides to be imported into the
United States.
    EPA is proposing these tolerance actions for atrazine to implement
the tolerance recommendations made during the reregistration and
tolerance reassessment processes. As part of these processes, EPA is
required to determine whether each of the amended tolerances meets the
safety standard of FQPA. The safety finding determination is discussed
in detail in the atrazine RED. REDs and TREDs recommend the
implementation of certain tolerance actions, including modifications to
reflect current use patterns, to meet safety findings, and change
commodity names and groupings in accordance with new EPA policy.
Printed and electronic copies of the REDs and TREDs are available as
provided in Unit II.A.
    REDs and TREDs contain the Agency's evaluation of the database for
these pesticides, including requirements for additional data on the
active ingredients to confirm the potential human health and
environmental risk assessments associated with current product uses,
and in REDs state conditions under which these uses and products will
be eligible for reregistration. The REDs and TREDs recommended the
establishment, modification, and/or revocation of specific tolerances.
RED and TRED recommendations such as establishing or modifying
tolerances, and in some cases revoking tolerances, are the result of
assessment under the FFDCA standard of ``reasonable certainty of no
harm.'' However, tolerance revocations recommended in REDs and TREDs
that are proposed in this document do not need such assessment when the
tolerances are no longer necessary.
    EPA's general practice is to propose revocation of tolerances for
residues of pesticide active ingredients on crops for which FIFRA
registrations no longer exist and on which the pesticide may therefore
no longer be used in the United States. EPA has historically been
concerned that retention of tolerances that are not necessary to cover
residues in or on legally treated foods may encourage misuse of
pesticides within the United States. Nonetheless, EPA will establish
and maintain tolerances even when corresponding domestic uses are
canceled if the tolerances, which EPA refers to as ``import
tolerances,'' are necessary to allow importation into the United States
of food containing such pesticide residues. However, where there are no
imported commodities that require these import tolerances, the Agency
believes it is appropriate to revoke tolerances for unregistered
pesticides in order to prevent potential misuse.
    Furthermore, as a general matter, the Agency believes that
retention of import

tolerances not needed to cover any imported food may result in
unnecessary restriction on trade of pesticides and foods. Under section
408 of FFDCA, a tolerance may only be established or maintained if EPA
determines that the tolerance is safe based on a number of factors,
including an assessment of the aggregate exposure to the pesticide and
an assessment of the cumulative effects of such pesticide and other
substances that have a common mechanism of toxicity. In doing so, EPA
must consider potential contributions to such exposure from all
tolerances. If the cumulative risk is such that the tolerances in
aggregate are not safe, then every one of these tolerances is
potentially vulnerable to revocation. Furthermore, if unneeded
tolerances are included in the aggregate and cumulative risk
assessments, the estimated exposure to the pesticide would be inflated.
Consequently, it may be more difficult for others to obtain needed
tolerances or to register needed new uses. To avoid potential trade
restrictions, the Agency is proposing to revoke tolerances for residues
on crops uses for which FIFRA registrations no longer exist, unless
someone expresses a need for such tolerances. Through this proposed
rule, the Agency is inviting individuals who need these import
tolerances to identify themselves and the tolerances that are needed to
cover imported commodities.
    Parties interested in retention of the tolerances should be aware
that additional data may be needed to support retention. These parties
should be aware that, under FFDCA section 408(f), if the Agency
determines that additional information is reasonably required to
support the continuation of a tolerance, EPA may require that parties
interested in maintaining the tolerances provide the necessary
information. If the requisite information is not submitted, EPA may
issue an order revoking the tolerance at issue.

C. When do these actions become effective?

    With the exception of certain existing tolerances for chloroneb,
clofencet, endosulfan, methidathion, and methyl parathion for which EPA
is proposing specific expiration/revocation dates and proposed new
tolerances to be established for endosulfan for which EPA is also
proposing expiration/revocation dates, the Agency is proposing that
these tolerance revocations, tolerance modifications, and revisions of
tolerance nomenclature and tolerance expression become effective on the
date of publication of the final rule in the Federal Register. With the
exception of the proposed expiration/revocation of specific (existing
and new) tolerances for chloroneb, clofencet, endosulfan, methidathion,
and methyl parathion, the Agency believes that existing stocks of
pesticide products labeled for the uses associated with the tolerances
proposed for revocation have been completely exhausted and that treated
commodities have cleared the channels of trade. EPA is proposing an
expiration/revocation date of April 16, 2012 for all of the chloroneb
tolerances proposed herein for revocation; July 14, 2012 for all of the
clofencet tolerances proposed herein for revocation; various dates for
the endosulfan tolerances proposed for revocation as described herein
in Unit II.A.; December 31, 2016 for all of the methidathion tolerances
proposed herein for revocation; and December 31, 2013 for the methyl
parathion tolerances proposed herein for revocation with the exception
of the tolerance on peanut. The Agency believes that these revocation
dates allow users to exhaust stocks and allows sufficient time for
passage of treated commodities through the channels of trade. However,
with the exception of endosulfan and methyl parathion whose registrants
have a Memorandum of Agreement with the Agency concerning canceled uses
and agreed dates for sale, distribution, and use of existing stocks, if
EPA is presented with information that existing stocks would still be
available and that information is verified, the Agency will consider
extending the expiration date of the tolerance. If you have comments
regarding existing stocks and whether the effective date allows
sufficient time for treated commodities to clear the channels of trade,
please submit comments as described under SUPPLEMENTARY INFORMATION.
    Any commodities listed in this proposal treated with the pesticides
subject to this proposal, and in the channels of trade following the
tolerance revocations, shall be subject to FFDCA section 408(1)(5), as
established by FQPA. Under this unit, any residues of these pesticides
in or on such food shall not render the food adulterated so long as it
is shown to the satisfaction of the Food and Drug Administration that:
    1. The residue is present as the result of an application or use of
the pesticide at a time and in a manner that was lawful under FIFRA,
and
    2. The residue does not exceed the level that was authorized at the
time of the application or use to be present on the food under a
tolerance or exemption from tolerance. Evidence to show that food was
lawfully treated may include records that verify the dates when the
pesticide was applied to such food.

III. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint U.N. Food and
Agriculture Organization/World Health Organization food standards
program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
    The Codex has not established a MRL for atrazine, chloroneb,
clofencet, N,N-diethyl-2-(4-methylbenzyloxy)ethylamine hydrochloride,
ethyl parathion, or MRL on lettuce for chlorpyrifos.
    The Codex has established MRLs for endosulfan in or on various
commodities including melons, except watermelon at 2 mg/kg and tea,
green, black at 30 mg/kg. These MRLs are different than the tolerances
established for endosulfan in the United States because of differences
in use patterns and/or good agricultural practices.
    The Codex has established MRLs for methidathion in or on various
commodities including apple at 0.5 mg/kg; cherries at 0.2 mg/kg;
cottonseed at 1 mg/kg; nectarine at 0.2 mg/kg; olives at 1 mg/kg; peach
at 0.2 mg/kg; pear at 1 mg/kg; and plums (including prunes) at 0.2 mg/
kg. These MRLs are different than the tolerances established for
methidathion in the United States because of differences in use
patterns and/or good agricultural practices.
    The Codex has established MRLs for methyl parathion (parathion-
methyl) in or on various commodities including potato at 0.05 mg/kg.
The MRL is different than the tolerance established for methyl
parathion in the United States because of differences in use patterns
and/or good agricultural practices.

IV. Statutory and Executive Order Reviews

    In this proposed rule, EPA is proposing to establish tolerances
under FFDCA section 408(e), and also modify and revoke specific
tolerances

established under FFDCA section 408. The Office of Management and
Budget (OMB) has exempted these types of actions (e.g., establishment
and modification of a tolerance and tolerance revocation for which
extraordinary circumstances do not exist) from review under Executive
Order 12866, entitled Regulatory Planning and Review (58 FR 51735,
October 4, 1993). Because this proposed rule has been exempted from
review under Executive Order 12866 due to its lack of significance,
this proposed rule is not subject to Executive Order 13211, entitled
Actions Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May 22, 2001). This proposed rule
does not contain any information collections subject to OMB approval
under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., or
impose any enforceable duty or contain any unfunded mandate as
described under Title II of the Unfunded Mandates Reform Act of 1995
(UMRA) (Pub. L. 104-4). Nor does it require any special considerations
as required by Executive Order 12898, entitled Federal Actions to
Address Environmental Justice in Minority Populations and Low-Income
Populations (59 FR 7629, February 16, 1994); or OMB review or any other
Agency action under Executive Order 13045, entitled Protection of
Children from Environmental Health Risks and Safety Risks (62 FR 19885,
April 23, 1997). This action does not involve any technical standards
that would require Agency consideration of voluntary consensus
standards pursuant to section 12(d) of the National Technology Transfer
and Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d)
(15 U.S.C. 272 note). Pursuant to the Regulatory Flexibility Act (RFA)
(5 U.S.C. 601 et seq.), the Agency previously assessed whether
establishment of tolerances, exemptions from tolerances, raising of
tolerance levels, expansion of exemptions, or revocations might
significantly impact a substantial number of small entities and
concluded that, as a general matter, these actions do not impose a
significant economic impact on a substantial number of small entities.
These analyses for tolerance establishments and modifications, and for
tolerance revocations were published on May 4, 1981 (46 FR 24950) and
on December 17, 1997 (62 FR 66020) (FRL-5753-1), respectively, and were
provided to the Chief Counsel for Advocacy of the Small Business
Administration. Taking into account this analysis, and available
information concerning the pesticides listed in this proposed rule, the
Agency hereby certifies that this proposed rule will not have a
significant negative economic impact on a substantial number of small
entities. In a memorandum dated May 25, 2001, EPA determined that eight
conditions must all be satisfied in order for an import tolerance or
tolerance exemption revocation to adversely affect a significant number
of small entity importers, and that there is a negligible joint
probability of all eight conditions holding simultaneously with respect
to any particular revocation. (This Agency document is available in the
docket of this proposed rule). Furthermore, for the pesticide named in
this proposed rule, the Agency knows of no extraordinary circumstances
that exist as to the present proposal that would change the EPA's
previous analysis. Any comments about the Agency's determination should
be submitted to the EPA along with comments on the proposal, and will
be addressed prior to issuing a final rule. In addition, the Agency has
determined that this action will not have a substantial direct effect
on States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132,
entitled Federalism (64 FR 43255, August 10, 1999). Executive Order
13132 requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.'' This
proposed rule directly regulates growers, food processors, food
handlers, and food retailers, not States. This action does not alter
the relationships or distribution of power and responsibilities
established by Congress in the preemption provisions of section
408(n)(4) of FFDCA. For these same reasons, the Agency has determined
that this proposed rule does not have any ``tribal implications'' as
described in Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 9,
2000). Executive Order 13175, requires EPA to develop an accountable
process to ensure ``meaningful and timely input by tribal officials in
the development of regulatory policies that have tribal implications.''
``Policies that have tribal implications'' is defined in the Executive
order to include regulations that have ``substantial direct effects on
one or more Indian tribes, on the relationship between the Federal
Government and the Indian tribes, or on the distribution of power and
responsibilities between the Federal Government and Indian tribes.''
This proposed rule will not have substantial direct effects on tribal
governments, on the relationship between the Federal Government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes, as specified in
Executive Order 13175. Thus, Executive Order 13175 does not apply to
this proposed rule.

    6. Section 180.257 is amended by revising paragraph (a) to read to
as follows:

Sec.  180.257  Chloroneb; tolerances for residues.

    (a) General. Tolerances are established for residues of the
fungicide chloroneb, 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 chloroneb, 1,4-dichloro-2,5-dimethoxybenzene,
and its metabolite 2,5-dichloro-4-methoxyphenol (free and conjugated),
calculated as the stoichiometric equivalent of chloroneb, in or on the
commodity.
