Chloroneb, Cypermethrin, Methidathion, Nitrapyrin, Oxyfluorfen, 
Pirimiphos-methyl, Sulfosate, Tebuthiuron, Thiabendazole, Thidiazuron, 
and Tribuphos; Proposed Tolerance Actions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to revoke certain tolerances for the 
fungicides chloroneb and thiabendazole; the herbicide sulfosate; the 
defoliant thidiazuron; the insecticides cypermethrin, methidathion, and 
pirimiphos-methyl; and the soil microbiocide nitrapyrin. Also, EPA is 
proposing to modify certain tolerances for the fungicides chloroneb and 
thiabendazole; the herbicides oxyfluorfen and tebuthiuron; the 
defoliants thidiazuron and tribuphos; the insecticides cypermethrin, 
methidathion, and pirimiphos-methyl; and the soil microbiocide 
nitrapyrin. In addition, EPA is proposing to establish new tolerances 
for the fungicides chloroneb and thiabendazole; the herbicide 
oxyfluorfen; the defoliants thidiazuron and tribuphos; the insecticides 
cypermethrin, methidathion, and pirimiphos-methyl; and the soil 
microbiocide nitrapyrin. 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).

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 time frames 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, remove, modify, and establish specific 
tolerances for residues of the fungicides chloroneb and thiabendazole; 
the herbicides oxyfluorfen, sulfosate, and tebuthiuron; the defoliants 
thidiazuron and tribuphos; the insecticides cypermethrin, methidathion, 
and pirimiphos-methyl; and the soil microbiocide nitrapyrin in or on 
commodities listed in the regulatory text.
    EPA is proposing these tolerance actions to implement the tolerance 
recommendations made during the reregistration and tolerance

[[Page 24200]]

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 the 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 1 (800) 490-9198; 
fax 1 (513) 489-8695; internet at http://www.epa.gov/ncepihom/ and from 

the National Technical Information Service (NTIS), 5285 Port Royal 
Road, Springfield, VA 22161, telephone 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 for chloroneb, cypermethrin, 
nitrapyrin, oxyfluorfen, tebuthiuron, and thidiazuron in public dockets 
EPA-HQ-OPP-2004-0369, EPA-HQ-OPP-2005-0293, EPA-HQ-OPP-2004-0283, EPA-
HQ-OPP-2002-0255, EPA-HQ-OPP-2002-0146, and EPA-HQ-OPP-2004-0382, 
respectively, at http://www.regulations.gov/ and for methidathion, pirimiphos-methyl, thiabendazole, and tribuphos at http://www.epa.gov/

pesticides/reregistration/status.htm. A RED for sulfosate was not 
needed because it was registered after November 1, 1984 and not subject 
to reregistration eligibility, and because its tolerances were 
reassessed at the time of the addition of a tolerance for a new use, as 
described below in Unit II.A., a TRED document was no longer needed for 
the purpose of tolerance reassessment.
    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; and
     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 paper copies for chloroneb, cypermethrin, nitrapyrin, 
tebuthiuron, and thidiazuron can be found under their respective public 
docket numbers, identified in Unit II.A. Paper copies for methidathion, 
oxyfluorfen, pirimiphos-methyl, thiabendazole, and tribuphos are 
available in the public docket for this 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 

docket number EPA-HQ-OPP-2007-0036, then click on that docket 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 domestic commodities legally 
treated.
    1. Chloroneb. Currently, chloroneb tolerances are set forth in 40 
CFR 180.257(a) for residues of chloroneb and its metabolite 2,5-
dichloro-4-methoxyphenol, calculated as chloroneb. The Agency 
determined, as described in the Residue Chemistry Chapter document, 
that residues of concern include the conjugate of 2,5-dichloro-4-
methoxyphenol. Therefore, EPA is proposing to revise the tolerance 
expression to include the conjugated as well as free metabolite in 40 
CFR 180.257(a) as follows:
    Tolerances are established for residues of the fungicide 
chloroneb (1,4-dichloro-2,5-dimethoxybenzene) and its metabolite 
2,5-dichloro-4-methoxyphenol (free and conjugated), calculated as 
chloroneb, in or on the following raw agricultural commodities.
    Also, in 40 CFR 180.257(a), EPA is proposing to remove the ``(N)'' 
designation from all entries to conform to current Agency 
administrative practice, where the ``(N)'' designation means negligible 
residues.
    The tolerance in 40 CFR 180.257(a) for chloroneb residues of 
concern in or on cotton, forage should be revoked because the Agency no 
longer considers this commodity to be a significant livestock feed 
item, and therefore, is no longer needed. Consequently, EPA is 
proposing to revoke the tolerance in 40 CFR 180.257(a) on cotton, 
forage.
    Based on available data from beans, undelinted cottonseed, 
soybeans, sugarbeet roots and sugarbeet tops that showed combined 
chloroneb residues of

[[Page 24201]]

concern at < 0.1 ppm, EPA determined that these tolerances should be 
increased from 0.1 ppm and set at the limit of quantitation (LOQ) of 
0.2 ppm. Therefore, the Agency is proposing in 40 CFR 180.257(a) to 
increase the tolerances to 0.2 ppm for the following: Bean and revise 
to bean, dry, seed and bean, succulent; beet, sugar, roots; beet, 
sugar, tops; cotton, undelinted seed; and soybean and revise to 
soybean, seed. 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.
    Based on the translation of available data from cowpea forage and 
soybean forage that showed combined chloroneb residues of concern as 
high as < 2.0 ppm, EPA determined that the expected residues on cowpea 
hay and soybean hay would be < 2.0 ppm and tolerances on cowpea hay and 
soybean hay should be established at 2.0 ppm. Therefore, the Agency is 
proposing in 40 CFR 180.257(a) to establish tolerances on cowpea, hay 
and soybean, hay, each at 2.0 ppm.
    Based on cotton metabolism data that showed combined chloroneb 
residues of concern from cottonseed treatment were as high as 0.256 ppm 
on cotton gin byproducts, EPA determined that a tolerance on cotton gin 
byproducts should be established at 1.0 ppm. Therefore, the Agency is 
proposing in 40 CFR 180.257(a) to establish a tolerance on cotton, gin 
byproducts at 1.0 ppm.
    In addition, EPA is proposing to revise commodity terminology in 
newly recodified 40 CFR 180.257(a) to conform to current Agency 
practice as follows: ``bean, forage'' to ``cowpea, forage.''
    There are no Codex MRLs for chloroneb.
    2. Cypermethrin. Based on available cattle exaggerated feeding data 
(0.83x and 2.8x maximum theoretical dietary burden or MTDB) for 
cypermethrin, EPA calculated that the maximum expected residues in 
muscle, fat, kidney, liver, whole milk and milk cream at 1x MTDB to be 
0.084 ppm, 0.699 ppm, 0.025 ppm, < 0.0036 ppm, 0.084 ppm, and 0.378 ppm, 
respectively. Therefore, the Agency determined that tolerances for the 
meat of cattle, goats, horses and sheep should be increased from 0.05 
to 0.2 ppm in order to harmonize with Codex, and tolerances for the fat 
of cattle, goats, horses, and sheep should be increased from 0.05 to 
1.0 ppm. In addition, the Agency determined that the tolerance level in 
40 CFR 180.418(a)(2) for zeta-cypermethrin on milk fat (reflecting 0.10 
in whole milk) at 2.5 ppm (based on a slightly higher theoretical 
dietary burden for cattle than cypermethrin) is also appropriate for 
cypermethrin and therefore the tolerance on milk should be revised to 
milk fat and increased from 0.05 to 2.5 ppm. Consequently, EPA is 
proposing to increase the tolerances in 40 CFR 180.418(a)(1) on cattle, 
meat; goat, meat; horse, meat; and sheep, meat to 0.2 ppm; cattle, fat; 
goat, fat; horse, fat; and sheep, fat to 1.0 ppm; and milk to 2.5 ppm 
and revise the commodity terminology to milk, fat (reflecting 0.10 in 
whole milk). 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.
    Based on available cattle exaggerated feeding data and a 10-fold 
lower MTDB of cypermethrin for swine in comparison with cattle, EPA 
calculated that the maximum expected residues in muscle, fat, kidney, 
and liver of swine at 1x MTDB to be 0.0084 ppm, 0.0699 ppm, 0.0025 ppm, 
and < 0.00036 ppm, respectively. Therefore, the tolerances on hog fat 
should be increased from 0.05 to 0.1 ppm in 40 CFR 180.418(a)(1) and 
decreased from 1.0 to 0.1 ppm in 40 CFR 180.418(a)(2). Consequently, 
EPA is proposing to increase the tolerance in 40 CFR 180.418(a)(1) on 
hog, fat to 0.1 ppm and decrease the tolerance on hog, fat in 40 CFR 
180.418(a)(2) to 0.1 ppm. Also, while the Agency determined that the 
tolerance on hog meat is adequate at 0.05 ppm in 40 CFR 180.418(a)(1), 
it believes that it should be decreased from 0.2 to 0.05 ppm in 40 CFR 
180.418(a)(2). Consequently, EPA is proposing to decrease the tolerance 
on hog, meat in 40 CFR 180.418(a)(2) to 0.05 ppm. In addition, because 
the Agency expects cypermethrin residues on kidney and liver to be 
below the livestock method LOQ of 0.05 ppm, it believes that there is 
no reasonable expectation of detecting finite residues of cypermethrin 
or zeta-cypermethrin residues in or on hog, meat byproducts and 
therefore the tolerances are no longer needed under 40 CFR 180.6(a)(3). 
Consequently, the Agency is proposing to revoke the tolerances on hog, 
meat byproducts in both 40 CFR 180.418(a)(1) and (a)(2). 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 poultry exaggerated feeding data (14.3x MTDB) of 
cypermethrin, EPA calculated that the maximum expected residues in 
kidney, liver, and muscle of poultry at 1x MTDB is each at < 0.0007 ppm, 
which is below the livestock method LOQ of 0.05 ppm and LOD of 0.01 
ppm, 0.02 ppm in poultry fat, and 0.0086 ppm in egg. Therefore, EPA 
determined that there is no reasonable expectation of detecting finite 
residues of cypermethrin in poultry meat or meat byproducts and the 
poultry meat byproducts tolerance in 180.418(a)(2) is no longer needed 
under 40 CFR 180.6(a)(3). However, the Agency believes that tolerances 
of 0.05 ppm should be established on egg, poultry fat, and poultry meat 
in order to harmonize with Codex. Consequently, the Agency is proposing 
to revoke the tolerances in 40 CFR 180.418(a)(2) on poultry, meat 
byproducts and establish tolerances in 40 CFR 180.418(a)(1) on egg; 
poultry, fat; and poultry, meat at 0.05 ppm.
    Based on available field trial data that showed cypermethrin 
residues as high as 3.4 ppm in or on head lettuce, EPA determined that 
the tolerance should be decreased from 10.0 to 4.0 ppm. Also, since the 
use of zeta-cypermethrin on head lettuce is covered by the tolerance on 
leafy vegetables except Brassica, the Agency has determined that the 
tolerance on head lettuce is no longer needed in 40 CFR 180.418(a)(2). 
Therefore, the Agency is proposing in 40 CFR 180.418(a)(1) to decrease 
the tolerance on lettuce, head to 4.0 ppm and revoke the tolerance on 
lettuce, head in 40 CFR 180.418(a)(2).
    Based on data that showed cypermethrin residues as high as 8.84 ppm 
in or on cotton gin byproducts, EPA determined that a tolerance on 
cotton gin byproducts should be established at 11.0 ppm. Therefore, the 
Agency is proposing in 40 CFR 180.418(a)(1) to establish a tolerance on 
cotton, gin byproducts at 11.0 ppm.
    Because the tolerance expired on June 30, 2005, EPA is proposing to 
remove the entry for the time-limited tolerance on mustard seed from 40 
CFR 180.418(b).
    In addition, EPA is proposing to revise commodity terminology to 
conform to current Agency practice as follows: in 40 CFR 180.418(a)(1), 
``onion, dry bulb'' to ``onion, bulb;'' and in 40 CFR 180.418(a)(2), 
``dried, shelled pea and bean, except soybean (Crop subgroup 6C)'' to 
``pea and bean, dried shelled, except soybean, subgroup 6C;'' ``edible 
podded legume vegetables (Crop subgroup 6A)'' to ``vegetable, legume, 
edible podded, subgroup 6A;'' ``leafy vegetables except Brassica'' to 
``vegetable, leafy, except brassica, group 4;'' ``onion, dry bulb'' to 
``onion, bulb;'' ``sorghum, forage'' to ``sorghum, grain, forage;'' 
``sorghum, grain'' to ``sorghum, grain, grain;'' ``succulent, shelled 
pea and bean (Crop subgroup 6B)'' to ``pea

[[Page 24202]]

and bean, succulent shelled, subgroup 6B;'' and ``vegetable, fruiting, 
except cucurbits (Crop group 8)'' to ``vegetable, fruiting, group 8.'' 
Because there is an existing tolerance on grass forage, in this case 
via a group tolerance, there is no need to include sorghum, forage, 
forage in the revision of the commodity terminology for sorghum forage.
    In the Federal Register of December 13, 2006 (71 FR 74802) (FRL-
8064-3), EPA published a direct final rule which finalized certain 
pesticide tolerance nomenclature changes. In both 40 CFR 180.418(a)(1) 
and (a)(2), the changes from ``Brassica leafy'' to ``Vegetable, 
brassica, leafy group 5'' were not correct because there are existing 
tolerances for subgroup 5A and therefore the terminology ``Brassica, 
leafy'' should have been changed so as to denote subgroup 5B. 
Therefore, EPA is proposing to revise ``Vegetable, brassica, leafy 
group 5'' (formerly ``Brassica, leafy'') to ``Brassica, leafy greens, 
subgroup 5B'' in both 40 CFR 180.418(a)(1) and (2).
    The proposed tolerance actions herein for cypermethrin and zeta-
cypermethrin, to implement the recommendations of the cypermethrin RED, 
reflect use patterns in the U.S. which support a different tolerance 
than the Codex value on Brassica vegetables, cottonseed, head lettuce, 
and milk because of differences in good agricultural practices and 
determination of secondary residue levels in livestock commodities. 
However, compatibility exists for bulb onions and meat byproducts, and 
will exist between the proposed reassessed U.S. tolerances and Codex 
MRLs for cypermethrin residues in or on egg, poultry meat; and meat of 
cattle, goats, horses, and sheep.
    3. Methidathion. Because residues of methidathion in or on pecans 
and walnut at 0.05 ppm and peach at 0.05 ppm are covered by the 
existing group tolerance on nut (0.05 ppm) and stone fruit (0.05 ppm), 
respectively, EPA determined that these individual tolerances are no 
longer needed, and therefore should be revoked. Consequently, EPA is 
proposing to revoke the tolerances in 40 CFR 180.298(a) on peach, 
pecan, and walnut.
    Based on available data that showed residues of methidathion as 
high as 3.6 ppm in or on oranges, EPA determined that the tolerance on 
citrus fruit (except mandarins) should be increased from 2.0 to 4.0 
ppm. Therefore, the Agency is proposing in 40 CFR 180.298(a) to revise 
the tolerance on fruit, citrus (except mandarins) to fruit, citrus, 
group 10, except tangerine and increase the tolerance to 4.0 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.
    Also, based on available data that showed residues of methidathion 
concentrate an average of 118x in oil processed from methidathion-
treated oranges, EPA determined that a tolerance on citrus oil should 
be established at 420.0 ppm. Therefore, the Agency is proposing in 40 
CFR 180.298(a) to establish a tolerance on citrus, oil at 420.0 ppm.
    The methidathion IRED recommended both recodifying the tolerances 
for alfalfa, alfalfa hay, grass, and grass hay (revising grass and 
grass hay to timothy and timothy hay) from 40 CFR 180.298(a) into (c) 
as regional tolerances and decreasing them from 12.0 to 5.0 ppm because 
section 24(c) FIFRA registrations had existed which allowed application 
to alfalfa and grass intended for haying, green chopping or grazing to 
be fed to livestock provided that the registrations were revised to 
impose a 21-day pre-harvest interval (PHI) and limited the amount of 
active ingredient per acre to timothy or timothy/alfalfa stands to 1 
pound per cutting. From available data that showed residues of 
methidathion ranged from 0.13 to 25.0 ppm up to 12 days post-
application and field trial data which demonstrated that residues of 
methidathion decline rapidly with time, EPA calculated that residues 
would be < 5.0 ppm with a 21-day PHI. However, while currently existing 
section 24(c) FIFRA registrations for use of methidathion on timothy 
and timothy hay have a 21-day PHI, a rate up to 1 lb. per acre per 
cutting, and a restriction against the grazing or harvesting of treated 
timothy and timothy hay for feeding to any animal that may enter the 
human food chain, one registration in Idaho that expires on December 
31, 2007 does not specify a restriction against treated hay, seed, or 
seed screenings from entering the human food chain (unlike the other 
registrations). Therefore, the Agency believes that the grass and grass 
hay tolerances would no longer be needed shortly after December 31, 
2007; i.e., after the Idaho registration expires. Consequently, EPA is 
proposing to recodify the tolerances on grass and grass, hay from 40 
CFR 180.298(a) to (c), revise their commodity terminology to timothy, 
forage and timothy, hay, respectively, decrease the tolerances from 
12.0 to 5.0 ppm, and revoke them with an expiration/revocation date of 
March 31, 2008.
    In addition, section 24(c) FIFRA registrations exist for 
methidathion use on alfalfa grown for seed production, a non-food/non-
feed use (that include restrictions against grazing/feeding on alfalfa, 
including seed, seed screenings and hay for human consumption or animal 
feed). However, while one of those registrations (for use on alfalfa 
with a 21-day PHI and rate up to 1 lb. per acre per cutting in Idaho 
that expires on December 31, 2007) has a restriction against the 
grazing or harvesting of treated alfalfa for feeding to any animal that 
may enter the human food chain, it does not specify a restriction 
against treated hay, seed, or seed screenings from entering the human 
food chain. Therefore, the Agency believes that the alfalfa and alfalfa 
hay tolerances would no longer be needed shortly after December 31, 
2007. Consequently, EPA is proposing to recodify the tolerances on 
alfalfa and alfalfa, hay from 40 CFR 180.298(a) to (c), decrease them 
to 5.0 ppm, revoke them with an expiration/revocation date of March 31, 
2008, and revise the commodity terminology for alfalfa to alfalfa, 
forage.
    Also, EPA is proposing to revise commodity terminology in 40 CFR 
180.298(a) to conform to current Agency practice as follows: ``fruit, 
pome'' to ``fruit, pome, group 11;'' ``fruit, stone'' to ``fruit, 
stone, group 12;'' ``nut'' to ``nut, tree, group 14;'' and ``sorghum, 
forage'' to ``sorghum, grain, forage'' and ``sorghum, forage, forage;'' 
``sorghum, grain'' to ``sorghum, grain, grain.''
    The proposed tolerance actions herein for methidathion, to 
implement the recommendations of the methidathion RED, reflect use 
patterns in the U.S. which support a different tolerance than the Codex 
value on citrus fruits (except tangerines), as well as tolerances on 
pome fruit, stone fruit, tangerines (mandarins), and safflower seeds, 
which are to be maintained at their existing levels. However, 
compatibility with Codex MRLs exists for U.S. tolerances on globe 
artichokes, grain sorghum, pecans, sunflower seeds, and walnuts.
    4. Nitrapyrin. Based on ruminant and poultry data feeding the 
maximum theoretical dietary burden of 6-chloropicolinic acid, EPA 
determined that there is no reasonable expectation of finite residues 
of nitrapyrin's metabolite 6-chloropicolinic acid, free or conjugated, 
in any livestock or poultry commodities. (Because 6-chloropicolinic 
acid is the only residue expected in crops treated with nitrapyrin, it 
was appropriate to feed 6-chloropicolinic acid instead of nitrapyrin). 
Therefore, tolerances on the fat, meat, and meat byproducts of cattle, 
goats, hogs, horses, sheep, and poultry are no longer needed under 40 
CFR

[[Page 24203]]

180.6(a)(3). Consequently, the Agency is proposing to revoke the 
tolerances in 40 CFR 180.350 for the combined residues of nitrapyrin 
and 6-chloropicolinic acid in or on cattle, fat; cattle, meat; cattle, 
meat byproducts; goat, fat; goat, meat; goat, meat byproducts; hog, 
fat; hog, meat; hog, meat byproducts; horse, fat; horse, meat; horse, 
meat byproducts; sheep, fat; sheep, meat; and sheep, meat byproducts; 
poultry, fat; poultry, meat; and poultry, meat byproducts.
    Based on available data showing combined nitrapyrin and 6-
chloropicolinic acid residues as high as 0.315 ppm on sorghum forage, 
EPA determined that the tolerance for sorghum forage should be 
increased from 0.1 to 0.5 ppm. Therefore, EPA is proposing to increase 
the tolerance in 40 CFR 180.350(a) on sorghum, forage to 0.5 ppm and 
revise it to ``sorghum, forage, forage'' and ``sorghum, grain, 
forage.'' 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 data showing combined nitrapyrin and 6-
chloropicolinic acid residues as high as 0.35 ppm on wheat grain, 1.436 
ppm on wheat forage, and 4.8 ppm on wheat straw, EPA determined that 
the tolerances for wheat grain, forage, and straw should be increased 
from 0.1 to 0.5 ppm, 0.5 to 2.0 ppm and 0.5 to 6.0 ppm, respectively. 
Therefore, EPA is proposing to increase the tolerances in 40 CFR 
180.350(a) on wheat, grain to 0.5 ppm, wheat, forage to 2.0 ppm, and 
wheat, straw to 6.0 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.
    Based on field trial data that supported an increased tolerance for 
wheat grain from 0.1 to 0.5 ppm and processing data that showed 
concentration of 6-chloropicolinic acid in wheat bran by 5.5x and wheat 
shorts by 2.2x, but not in flour (nitrapyrin was not detectable in any 
processed wheat product), EPA determined that tolerances should be 
established for wheat bran at 3.0 ppm and wheat milled byproducts, 
except flour at 2.0 ppm. Therefore, the Agency is proposing to 
establish tolerances in 40 CFR 180.350(a) for combined residues of 
nitrapyrin and its metabolite 6-chloropicolinic acid in or on wheat, 
bran at 3.0 ppm, and wheat, milled byproducts, except flour at 2.0 ppm.
    Based on field trial data that supported a tolerance of 0.1 ppm for 
corn grain and processing data that showed concentration of 6-
chloropicolinic acid in field corn screenings and grits after both dry 
and wet milling by 1.4x and 1.45x, respectively, but not in sweet corn 
fractions processed from sweet corn, EPA determined that a tolerance 
should be established for field corn milled byproducts at 0.2 ppm. 
Therefore, the Agency is proposing to establish a tolerance in 40 CFR 
180.350(a) for combined residues of nitrapyrin and its metabolite 6-
chloropicolinic acid in or on corn, field, milled byproducts at 0.2 
ppm.
    Also, in 40 CFR 180.350(a), EPA is proposing to remove the ``(N)'' 
designation from all entries to conform to current Agency 
administrative practice, where the ``(N)'' designation means negligible 
residues.
    In addition, in 40 CFR 180.350(a), EPA is proposing to revise the 
commodity terminology for ``corn, forage'' to ``corn, field, forage'' 
and ``corn, sweet, forage;'' ``corn, grain'' to ``corn, field, grain'' 
and ``corn, pop, grain;'' ``corn, stover'' to ``corn, field, stover,'' 
``corn, pop, stover,'' and ``corn, sweet, stover;'' and ``sorghum, 
grain'' to ``sorghum, grain, grain.''
    There are no Codex MRLs for nitrapyrin.
    5. Oxyfluorfen. Based on available data that showed residues of 
oxyfluorfen as high as 0.03 ppm in or on mint hay, EPA determined that 
the tolerance on mint hay (peppermint and spearmint) should be 
decreased from 0.1 to 0.05 ppm. Therefore, the Agency is proposing in 
40 CFR 180.381(a) to revise the commodity terminology for mint hay into 
separate tolerances on peppermint, tops and spearmint, tops and 
decrease each tolerance to 0.05 ppm.
    Based on available exaggerated (5x to 7x MTDB) cattle feeding data 
that showed residues of oxyfluorfen as high as < 0.003 ppm in milk, 
0.007 ppm in fat, < 0.003 ppm in meat, < 0.003 ppm in kidney, and < 0.003 
ppm in liver, EPA expected residues below the LOQ (0.01 ppm) in milk, 
fat, meat, and meat byproducts at the 1x MTDB for cattle. The Agency 
determined that the tolerances on milk and the fat, meat and meat 
byproducts of cattle, goats, hogs, horses, and sheep should be set at 
the LOQ and decreased from 0.05 to 0.01 ppm. Therefore, EPA is 
proposing in 40 CFR 180.381(a) to decrease the tolerances on milk; 
cattle, fat; cattle, meat; cattle, meat byproducts; goat, fat; goat, 
meat; goat, meat byproducts; hog, fat; hog, meat; hog, meat byproducts; 
horse, fat; horse, meat; horse, meat byproducts; sheep, fat; sheep, 
meat; and sheep, meat byproducts to 0.01 ppm.
    Based on available exaggerated (2.0x MTDB) poultry feeding data 
that showed residues of oxyfluorfen as high as 0.024 ppm in eggs, 0.163 
ppm in fat, 0.004 ppm in meat, and 0.006 ppm in liver, EPA expected 
residues of 0.012 ppm in egg, 0.082 ppm in fat, 0.002 ppm in meat, and 
0.003 ppm in liver at the 1x MTDB for poultry. The Agency determined 
that the tolerances should be decreased on egg from 0.05 to 0.03 ppm, 
meat and meat byproducts from 0.05 to 0.01 ppm, and increased on fat 
from 0.05 to 0.2 ppm. Therefore, EPA is proposing in 40 CFR 180.381(a) 
to decrease the tolerances on egg to 0.03 ppm, poultry, meat to 0.01 
ppm, poultry, meat byproducts to 0.01 ppm, and increase the tolerance 
on poultry, fat to 0.2 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 data that showed oxyfluorfen residues from use 
of oxyfluorfen on grass grown for seed in Oregon and Washington were 
not detectable (< 0.03 ppm) in or on grass forage, hay, and seed 
screenings, EPA determined that the reassessed animal commodity 
tolerances are adequate to cover any residue contribution from regional 
registration uses of oxyfluorfen on grasses grown for seed and 
tolerances should be established on grass forage, hay, and seed 
screenings at 0.05 ppm. Therefore, the Agency is proposing to establish 
tolerances in 40 CFR 180.381(c) on grass, forage; grass, hay; and 
grass, seed screenings; each at 0.05 ppm.
    In addition, EPA is proposing to revise commodity terminology in 40 
CFR 180.381 to conform to current Agency practice as follows: ``banana 
(including plantain)'' to ``banana;'' ``coffee, bean'' to ``coffee, 
bean, green;'' ``corn, grain'' to ``corn, field, grain'' and ``corn, 
pop, grain;'' ``onion, dry bulb'' to ``onion, bulb;'' ``taro, corm and 
leaves'' to ``taro, corm'' and ``taro, leaves. Moreover, it should be 
noted that use of oxyfluorfen on plantains is covered by the existing 
tolerance at 0.05 ppm for banana under 40 CFR 180.1(g), and there is no 
need to establish a separate tolerance on plantains at 0.05 ppm. Also, 
because use of oxyfluorfen on garlic is covered by the existing 
tolerance at 0.05 ppm for onion bulb under 40 CFR 180.1(g), there is no 
need to establish a separate tolerance on garlic at 0.05 ppm as had 
been recommended in the RED.
    There are no Codex MRLs for oxyfluorfen.

[[Page 24204]]

    6. Pirimiphos-methyl. Currently, pirimiphos-methyl tolerances are 
established in 40 CFR 180.409 and expressed for the combined residues 
of the insecticide parent and metabolite O-(2-ethylamino-6-methyl-
pyrimidin-4-yl) O,O-dimethyl phosphorothioate and, in free and 
conjugated form, the metabolites 2-diethylamino-6-methyl-pyrimidin-4-
ol, 2-ethylamino-6-methyl-pyrimidin-4-ol, and 2-amino-6-methyl-
pyrimidin-4-ol. However, because EPA has determined that the endpoint 
chosen for dietary risk assessment is cholinesterase inhibition, the 
non-cholinesterase-inhibiting hydroxypyrimidine metabolites no longer 
need to be included for the purpose of tolerance regulation. Also, in 
an effort to harmonize with Codex, the Agency determined that the 
residue to be regulated in commodities is pirimiphos-methyl per se. 
Therefore, EPA is proposing in 40 CFR 180.409(a) to revise the 
tolerance expression to residues of pirimiphos-methyl per se as 
follows:
    Tolerances are established for residues of the insecticide 
pirimiphos-methyl (O-(2-diethylamino-6-methyl-4-pyrimidinyl) O,O-
dimethyl phosphorothioate) in or on the following raw agricultural 
commodities.

    Based on available exaggerated (4x to 40x MTDB) cattle feeding data 
from which EPA determined that detectable residues are not reasonably 
expected in meat, and residues calculated at 1x MTDB would be expected 
at 0.01 ppm in fat, and < 0.01 ppm in both kidney and liver, the Agency 
determined that tolerances should be decreased and set at the LOQ of 
0.02 ppm for residues in the fat and meat byproducts of ruminants and 
fat in poultry. Because the tolerances on kidney and liver of cattle, 
goats, hogs, horses, and sheep should be decreased from 2.0 to 0.02 ppm 
and tolerances on meat byproducts of cattle, goats, hogs, horses, and 
sheep should be decreased from 0.2 to 0.02 ppm, residues in or on liver 
and kidney will be covered by the reassessed tolerances on meat 
byproducts and separate tolerances on kidney and liver are no longer 
needed and should be revoked. Therefore, EPA is proposing in 40 CFR 
180.409(a) to revoke the separate tolerances on cattle, kidney; cattle, 
liver; goat, kidney; goat, liver; hog, kidney; hog, liver; horse, 
kidney; horse, liver; sheep, kidney; and sheep, liver; and decrease the 
tolerances on cattle, fat; cattle, meat byproducts; goat, fat; goat, 
meat byproducts; hog, fat; hog, meat byproducts; horse, fat; horse, 
meat byproducts; poultry, fat; sheep, fat; and sheep, meat byproducts 
to 0.02 ppm.
    Based on the cattle feeding data, with current registrations, the 
tolerance for cattle meat can be classified under 40 CFR 180.6(a)(3); 
i.e. there is no reasonable expectation of finite residues, and 
therefore was recommended by the Agency in the pirimiphos-methyl RED to 
be revoked. In the Federal Register of July 31, 2002 (67 FR 49606) 
(FRL-7191-4), EPA published a rule which finalized certain tolerance 
actions for a number of pesticide active ingredients, including 
pirimiphos-methyl. In a response to a comment from Schering-Plough 
Animal Health Corporation on cattle tolerances and pending registration 
of a pour-on product, the Agency announced that it would not take 
action on revoking the tolerance for cattle meat at that time. However, 
since then, the pending registration application for a pour-on product 
formulation was withdrawn by Schering-Plough Animal Health Corporation. 
Currently, there are still active ear tag registrations. The Agency has 
determined that the use of impregnated materials (ear tags) on non-
lactating dairy cattle and beef cattle does not contribute to 
significant secondary residues in livestock (calculated contribution is 
a dietary equivalent to < 0.01 ppm, which is less than the dietary LOQ 
of 0.02 ppm). Therefore, under 40 CFR 180.6(a)(3), EPA is proposing to 
revoke the tolerance in 40 CFR 180.409 on cattle, meat.
    While there is a Codex MRL for pirimiphos-methyl on meat at 0.01 
mg/kg, EPA notes that the definition of ``meat'' under Codex is 
different than in U.S. tolerances and Codex has not established 
pirimiphos-methyl MRLs for fat or meat byproducts.
    Based on available processing data that showed residues of 
pirimiphos-methyl with an average concentration factor of 3.8x in 
aspirated grain fractions of corn and a highest average field trial 
(HAFT) of 4.87 ppm in or on corn grain, EPA determined that a tolerance 
should be established at 20.0 ppm. Therefore, EPA is proposing to 
establish a tolerance in 40 CFR 180.409(a) on grain, aspirated 
fractions at 20.0 ppm.
    In addition, EPA is proposing to revise commodity terminology in 40 
CFR 180.409 to conform to current Agency practice as follows: ``corn'' 
to ``corn, field, grain'' and ``corn, pop, grain.''
    7. Sulfosate. Because sulfosate was registered after November 1, 
1984, it was not subject to eligibility for reregistration under FIFRA 
and therefore a RED was not needed. Existing tolerances were reassessed 
according to the FQPA standard when new tolerances were established on 
September 11, 1998 (63 FR 48597)(FRL-6026-6) and therefore a TRED was 
not needed. However, the last U.S. registrations for the herbicide 
sulfosate (sulfonium, trimethyl-salt with N- (phosphonomethyl)glycine 
(1:1)) were canceled on October 15, 2004, due to non-payment of 
registration maintenance fees, and a notice was published in the 
Federal Register on October 27, 2004 (69 FR 62666)(FRL-7683-7). 
Therefore, the tolerances are no longer needed. In the Federal Register 
notice of October 27, 2004 (69 FR 62666), EPA stated that cancellation 
orders generally permit registrants to continue to sell and distribute 
existing stocks of the canceled products until January 15, 2005. 
However, during follow-up communication, the registrant informed the 
Agency that it did not produce sulfosate after 2002 and sold the 
remaining existing stocks of sulfosate in 2003. Nor is the registrant 
supporting the import tolerance on banana. Therefore, the Agency 
believes that end users have had sufficient time to exhaust existing 
stocks and for treated commodities to have cleared the channels of 
trade.
    Consequently, EPA is proposing to revoke tolerances in 40 CFR 
180.489 on the following: Almond, hulls (of which no more than 0.30 ppm 
is trimethylsulfonium (TMS)); banana (imported only); cattle, fat; 
cattle, kidney; cattle, meat byproducts, except kidney; cattle, meat; 
corn, field, forage; corn, field and pop, grain (of which no more than 
0.10 ppm is TMS); corn, field and pop, stover (of which no more than 
0.20 ppm is TMS); corn, sweet, forage (of which no more than 5.0 ppm is 
TMS); corn, sweet, kernel plus cob with husks removed (of which no more 
than 0.10 ppm is TMS); corn, sweet, stover (of which no more than 65 
ppm is TMS); cotton, gin byproducts (of which no more than 35 ppm is 
TMS); cotton, undelinted seed (of which no more than 10 ppm is TMS); 
crop group 2: Leaves of root and tuber vegetables (human food or animal 
feed (except radish) group (of which no more than 0.20 ppm is TMS); 
crop group 8: Vegetable, fruiting (except cucurbits) group; crop 
subgroup 1-A: Root vegetables (except radish) subgroup (of which no 
more than 0.10 ppm is TMS); crop subgroup 1-C: Tuberous and corm 
vegetables subgroup (of which no more than 0.50 ppm is TMS); crop 
subgroup 6-A: Edible-podded legume vegetables subgroup (of which no 
more than 0.3 ppm is TMS); crop subgroup 6-B: Succulent shelled pea and 
bean subgroup (of which no more than 0.1 ppm is TMS); crop subgroup 6C: 
Dried shelled pea and bean (except soybean and animal feed) subgroup 
(of which no

[[Page 24205]]

more than 1.5 ppm is TMS); egg; fruit, citrus, group 10; fruit, pome, 
group 11; fruit, stone, group 12; goat, fat; goat, kidney; goat, meat 
byproducts, except kidney; goat, meat; grain, aspirated fractions (of 
which no more than 720 ppm is TMS); grape; grape, raisin (of which no 
more than 0.05 ppm is TMS); hog, fat; hog, kidney; hog, meat 
byproducts, except kidney; hog, meat; horse, fat; horse, kidney; horse, 
meat byproducts, except kidney; horse, meat; milk; nut, tree, group 14; 
pistachio; poultry, fat; poultry, meat byproducts; poultry, meat; prune 
(of which no more than 0.05 ppm is TMS); radish, roots (of which no 
more than 15 ppm is TMS); radish, tops (of which no more than 8.0 ppm 
is TMS); sheep, fat; sheep, kidney; sheep, meat byproducts, except 
kidney; sheep, meat; sorghum, grain, forage (of which no more than 0.10 
ppm is TMS); sorghum, grain, grain (of which no more than 15 ppm is 
TMS); sorghum, grain, stover (of which no more than 60 ppm is TMS); 
soybean, forage (of which no more than 1 ppm is TMS); soybean, hay (of 
which no more than 2 ppm is TMS); soybean, hulls (of which no more than 
25 ppm is TMS); soybean, seed (of which no more than 13 ppm is TMS); 
wheat, bran (of which no more than 6.0 ppm is TMS); wheat, forage (of 
which no more than 30 ppm is TMS); wheat, grain (of which no more than 
2.5 ppm is TMS); wheat, hay (of which no more than 0.50 ppm is TMS); 
wheat shorts (of which no more than 0.5 ppm is TMS); wheat, shorts (of 
which no more than 5.0 ppm is TMS); wheat, straw (of which no more than 
0.5 ppm is TMS); and wheat, straw (of which no more than 40 ppm is 
TMS).
    8. Tebuthiuron. Currently, the tolerance expression in 40 CFR 
180.390 regulates for the herbicide tebuthiuron and its metabolites 
containing the dimethylethyl thiadiazole moiety. Because the Agency has 
determined that the residues of concern in plants are tebuthiuron and 
its metabolites N-(5-(2-hydroxy-1,1-dimethylethyl)-1,3,4-thiadiazol-2-
yl)-N,N'-dimethylurea, N-(5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-
N-methylurea, and N-(5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-N'-
hydroxymethyl-N-methylurea, EPA is proposing to revise the tolerance 
expression for plant commodities from 40 CFR 180.390 to 180.390(a)(1) 
with tolerances established for the combined residues of tebuthiuron 
(N-(5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-N,N'-dimethylurea) and 
its metabolites N-(5-(2-hydroxy-1,1-dimethylethyl)-1,3,4-thiadiazol-2-
yl)-N,N'-dimethylurea, N-(5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-
N-methylurea, and N-(5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-N'-
hydroxymethyl-N-methylurea.
    Also, because the Agency has determined that the residues of 
concern in fat, meat, kidney, and liver are tebuthiuron and its 
metabolites N-(5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-N-
methylurea, N-(5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)urea, 2-
dimethylethyl-5-amino-1,3,4-thiadiazole, and N-(5-(1,1-dimethylethyl)-
1,3,4-thiadiazol-2-yl)-N'-hydroxymethyl-N-methylurea, EPA is proposing 
to revise the tolerance expression for these animal commodities from 40 
CFR 180.390 to 180.390(a)(2) with tolerances established for the 
combined residues of tebuthiuron (N-(5-(1,1-dimethylethyl)-1,3,4-
thiadiazol-2-yl)-N,N'-dimethylurea) and its metabolites N-(5-(1,1-
dimethylethyl)-1,3,4-thiadiazol-2-yl)-N-methylurea, N-(5-(1,1-
dimethylethyl)-1,3,4-thiadiazol-2-yl)urea, 2-dimethylethyl-5-amino-
1,3,4-thiadiazole, and N-(5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-
N'-hydroxymethyl-N-methylurea.
    In addition, because the Agency has determined that the residues of 
concern in milk are tebuthiuron and its metabolites N-(5-(1,1-
dimethylethyl)-1,3,4-thiadiazol-2-yl)-N-methylurea, N-(5-(2-hydroxy-
1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-N-methylurea, N-(5-(1,1-
dimethylethyl)-1,3,4-thiadiazol-2-yl)urea, N-(5-(1,1-dimethylethyl)-
1,3,4-thiadiazol-2-yl)-N'-hydroxymethyl-N-methylurea, and N-(5-(2-
hydroxy-1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-N'-hydroxymethyl-N-
methylurea, EPA is proposing to revise the tolerance expression for 
milk from 40 CFR 180.390 to 180.390(a)(3) with a tolerance established 
for the combined residues of tebuthiuron (N-(5-(1,1-dimethylethyl)-
1,3,4-thiadiazol-2-yl)-N,N'-dimethylurea) and its metabolites N-(5-
(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-N-methylurea, N-(5-(2-
hydroxy-1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-N-methylurea, N-(5-
(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)urea, N-(5-(1,1-
dimethylethyl)-1,3,4-thiadiazol-2-yl)-N'-hydroxymethyl-N-methylurea, 
and N-(5-(2-hydroxy-1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl)-N'-
hydroxymethyl-N-methylurea.
    Based on the MTDB for beef cattle and available exaggerated 
ruminant feeding data (2.07x), combined tebuthiuron residues of concern 
in the milk, fat, meat, kidney, and liver of cattle were expected by 
the Agency at 1x to be as high as 0.57 ppm, 0.39 ppm, 0.67 ppm, 1.66 
ppm, and 3.44 ppm, respectively. Therefore, tolerances on the fat and 
meat of cattle, goats, horses, and sheep should be decreased from 2.0 
to 1.0 ppm; tolerances on meat byproducts of cattle, goats, horses, and 
sheep should be increased from 2.0 to 5.0 ppm; and tolerance on milk 
should be increased from 0.3 to 0.8 ppm. Consequently, EPA is proposing 
in 40 CFR 180.390(a)(2) to decrease tolerances on cattle, fat; cattle, 
meat; goat, fat; goat, meat; horse, fat; horse, meat; sheep, fat; and 
sheep, meat to 1.0 ppm; and increase tolerances on cattle, meat 
byproducts; goat, meat byproducts; horse, meat byproducts; and sheep, 
meat byproducts to 5.0 ppm. Also, EPA is proposing in 40 CFR 
180.390(a)(3) to increase the tolerance on milk to 0.8 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.
    Also, EPA is proposing to revise 40 CFR 180.390 by adding separate 
paragraphs (b), (c), and (d), and reserving those sections for 
tolerances with section 18 emergency exemptions, regional 
registrations, and indirect or inadvertent residues, respectively.
    There are no Codex MRLs for tebuthiuron.
    9. Thiabendazole. Currently, thiabendazole tolerances are 
established in 40 CFR 180.242(a)(1) and expressed for residues of the 
fungicide thiabendazole (2-(4-thiazolyl)benzimidazole in or on plant 
commodities. However, EPA has determined that for the purpose of 
tolerance regulation that its metabolite benzimidazole (free and 
conjugated) should be included as a residue of concern in or on plant 
commodities. Therefore, EPA is proposing in 40 CFR 180.242(a)(1) to 
revise the tolerance expression as follows:
    Tolerances are established for the combined residues of the 
fungicide thiabendazole (2-(4-thiazolyl)benzimidazole) and its 
metabolite benzimidazole (free and conjugated) in or on the 
following raw agricultural commodities.
    Currently, thiabendazole tolerances are established in 40 CFR 
180.242(a)(2) and expressed for combined residues of thiabendazole and 
its metabolite 5-hydroxythiabendazole in or on animal commodities. 
However, EPA has determined that for the purpose of tolerance 
regulation that its metabolites 5-hydroxythiabendazole (free and 
conjugated) and benzimidazole should be included as residues of concern 
in animal commodities. Therefore, EPA is proposing in 40 CFR 
180.242(a)(2) to revise the tolerance expression as follows:
    Tolerances are established for the combined residues of 
thiabendazole (2-(4-

[[Page 24206]]

thiazolyl)benzimidazole) and its metabolites 5-hydroxythiabendazole 
(free and conjugated) and benzimidazole in or on the following raw 
agricultural commodities.

    Currently, time-limited thiabendazole tolerances for emergency 
exemptions are established in 40 CFR 180.242(b) and expressed for 
residues of thiabendazole. However, EPA has determined that for the 
purpose of tolerance regulation that its metabolite benzimidazole (free 
and conjugated) should be included as a residue of concern in plant 
commodities. Therefore, EPA is proposing in 40 CFR 180.242(b) to revise 
the tolerance expression as follows:
    Time-limited tolerances are established for the combined 
residues of thiabendazole (2-(4-thiazolyl)benzimidazole) and its 
metabolite benzimidazole (free and conjugated), in connection with 
use of the pesticide under section 18 emergency exemptions granted 
by EPA. The tolerances are specified in the following table. The 
tolerances will expire on the dates specified in the table.

    Because thiabendazole residues of concern on postharvest banana 
pulp will be covered by the tolerance in 40 CFR 180.242(a)(1) on 
banana, postharvest at 3.0 ppm, a separate tolerance on postharvest 
banana pulp at 0.4 ppm is no longer needed, and therefore that 
tolerance on postharvest banana pulp should be revoked. Furthermore, 
currently, the Agency considers the raw agricultural commodity to be 
the whole banana and not just the pulp. Therefore, EPA is proposing to 
revoke the tolerance in 40 CFR 180.242(a)(1) for thiabendazole residues 
of concern in or on banana, pulp, postharvest.
    Because there have been no registered uses of thiabendazole for 
squash since 1993 and rice since 1999, the tolerances on hubbard 
squash, rice hulls, rice rough, and rice straw are no longer needed. 
Therefore, EPA is proposing to revoke the tolerances in 40 CFR 
180.242(a)(1) for thiabendazole residues of concern in or on squash, 
hubbard; rice, hulls; rice, rough; and rice, straw.
    Based on available processing data that showed residues of 
thiabendazole do not concentrate in any regulated processed commodity 
of potato (granules/flakes, chips, or wet peel) or wheat (bran, flour, 
middlings, shorts, germ), the Agency determined that the tolerances on 
processing waste of potato and milled fractions (excluding flour) of 
wheat are no longer needed. Therefore, EPA is proposing to revoke 
tolerances in 40 CFR 180.242(a)(1) on potato, processing waste (pre- & 
post-H) and wheat, milled fractions (except flour).
    Based on available processing data that showed residues of 
thiabendazole concentrated in dried citrus pulp by a factor of 1.6x and 
a HAFT of 5.2 ppm for whole citrus fruits, EPA expected residues of 8.3 
ppm, which is below the current and reassessed tolerance of 10.0 ppm on 
whole citrus fruit. Therefore, the dried citrus pulp tolerance is no 
longer needed. Consequently, EPA is proposing to revoke the tolerance 
in 40 CFR 180.242(a)(1) on citrus, dried pulp, postharvest.
    Based on the MTDB for poultry and available exaggerated (125x MTDB) 
poultry feeding data which showed combined thiabendazole residues of 
concern in poultry tissues at < 0.109 ppm and in egg yolks at 0.065 ppm, 
the Agency expects residues to be < 0.027 ppm in poultry tissues and 
0.015 ppm in eggs. Because these levels are below the combined LOQs of 
0.3 ppm in tissues and 0.15 ppm in eggs for the enforcement method, the 
Agency concluded that there is no reasonable expectation of finding 
finite thiabendazole residues of concern in poultry tissues and eggs 
resulting from the feeding of thiabendazole treated crops to poultry. 
Therefore, tolerances on poultry and eggs are no longer needed. 
Consequently, under 40 CFR 180.6(a)(3), EPA is proposing to revoke 
tolerances in 40 CFR 180.242(a)(2) on poultry; poultry, meat 
byproducts; poultry, meat; and egg.
    Based on the MTDB for beef cattle and swine and available 
exaggerated ruminant feeding data (1.9x and 6.7x MTDB in fat and 
muscle, respectively), combined thiabendazole residues of concern in 
the fat and meat of cattle were as high as 0.030 and 0.023 ppm, 
respectively. Because each of these levels is below the combined LOQ 
(0.1 ppm for each analyte), the Agency concluded that there is no 
reasonable expectation of finding finite thiabendazole residues of 
concern in the fat and meat of cattle, goats, hogs, horses, and sheep 
resulting from the feeding of thiabendazole treated crops to livestock. 
Therefore, tolerances on the fat of cattle, goats, hogs, horses, and 
sheep are no longer needed. Consequently, under 40 CFR 180.6(a)(3), EPA 
is proposing to revoke tolerances in 40 CFR 180.242(a)(2) on cattle, 
fat; goat, fat; hog, fat; horse, fat; and sheep, fat.
    The proposed changes to include the metabolite benzimidazole in the 
tolerance expression for thiabendazole when finalized could make U.S. 
tolerances and Codex MRLs incompatible because the Codex MRLs for 
thiabendazole are currently expressed in terms of the parent for plant 
commodities and sum of the parent and 5-hydroxythiabendazole for animal 
commodities. Because of the lack of Codex MRLs on the meat of goats, 
hogs, horses, and sheep; proposed change in the tolerance expression 
for animal commodities, and data that show no reasonable expectation of 
finding finite thiabendazole residues of concern in the meat of cattle, 
goats, hogs, horses, and sheep, the Agency determined that the meat 
tolerances of goats, hogs, horses, and sheep are no longer needed and 
therefore should be revoked. Consequently, under 40 CFR 180.6(a)(3), 
EPA is proposing to revoke tolerances in 40 CFR 180.242(a)(2) on goat, 
meat; hog, meat; horse, meat; and sheep, meat. However, despite the 
expected difference in tolerance expression and undetectable residues, 
EPA is maintaining the tolerance on cattle meat at 0.1 ppm in order to 
harmonize as closely as possible with the Codex MRL of 0.1 mg/kg.
    Based on available ruminant feeding data (1x MTDB) that showed 
combined thiabendazole residues of concern as high as 0.028 ppm in 
milk, which is below the combined LOQ of 0.1 ppm for the enforcement 
method, EPA determined that the tolerances on milk should be decreased 
from 0.4 to 0.1 ppm. Therefore, the Agency is proposing to decrease the 
tolerance in 40 CFR 180.242(a)(2) on milk to 0.1 ppm.
    Based on available exaggerated (1.9x MTDB) ruminant feeding data 
that showed combined thiabendazole residues of concern as high as 0.28 
ppm in liver and 0.687 ppm in kidney, EPA expected residues of 0.15 ppm 
in liver and 0.36 ppm in kidney at the 1x MTDB for beef cattle. The 
Agency determined that the tolerance for meat byproducts of cattle, 
goats, horses, and sheep should be increased from 0.1 to 0.4 ppm. 
Therefore, EPA is proposing to increase the tolerances in 40 CFR 
180.242(a)(2) on cattle, meat byproducts; goat, meat byproducts; horse, 
meat byproducts; and sheep, meat byproducts to 0.4 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 exaggerated ruminant feeding data and 14.7x MTDB 
for swine that showed combined thiabendazole residues of concern as 
high as 0.28 ppm in liver and 0.687 ppm in kidney, the Agency 
determined that the tolerance for combined thiabendazole residues of 
concern on hog meat byproducts should be increased from 0.1 ppm and set 
at the combined LOQ of 0.3 ppm for the analytes in the enforcement 
method. Therefore, EPA is proposing to increase the tolerance in 40 CFR 
180.242(a)(2) on

[[Page 24207]]

hog, meat byproducts 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.
    Based on available data showing combined thiabendazole residues of 
concern as high as < 0.022 ppm on sweet potatoes grown from treated seed 
roots, EPA determined that the postharvest tolerance for sweet potato 
from treated seed should be increased from 0.02 to 0.05 ppm. Therefore, 
EPA is proposing to increase the tolerance in 40 CFR 180.242(a)(1) on 
sweet potato (post-H to sweet potato intended only for use as seed) to 
0.05 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 data that showed combined thiabendazole residues 
of concern as high as 5.0 ppm in or on pears and a HAFT for 3.4 ppm for 
apples, EPA determined that the tolerances on apples and pears should 
be decreased from 10.0 to 5.0 ppm and combined into a group tolerance. 
Therefore, the Agency is proposing to decrease the tolerances in 40 CFR 
180.242(a)(1) on apple, postharvest and pear, postharvest and combine 
them into a group tolerance for fruit, pome, group 11, postharvest at 
5.0 ppm.
    Based on available processing data that showed residues of 
thiabendazole concentrated in wet apple pomace by a factor of 3.5x and 
a HAFT of 3.4 ppm for apples, EPA expected combined residues of 11.9 
ppm in wet apple pomace. Therefore, the Agency determined that a 
tolerance on wet apple pomace should be established at 12.0 ppm. 
Consequently, EPA is proposing to establish a tolerance in 40 CFR 
180.242(a)(1) on apple, wet pomace at 12.0 ppm.
    Based on available processing data that showed residues of 
thiabendazole concentrated in citrus oil by an average factor of 2.4x 
and a HAFT of 5.2 ppm for whole citrus fruits, EPA expected combined 
residues of 12.5 ppm in citrus oil. Therefore, the Agency determined 
that a tolerance on citrus oil should be established at 15.0 ppm. 
Consequently, EPA is proposing to establish a tolerance in 40 CFR 
180.242(a)(1) on citrus, oil at 15.0 ppm.
    In addition, EPA is proposing to revise commodity terminology in 40 
CFR 180.242(a)(1) to conform to current Agency practice as follows: 
``fruit, citrus, postharvest'' to ``fruit, citrus, group 10, 
postharvest.''
    Currently, there is an active registration for thiabendazole use on 
sugar beets. The registrant does not intend to support the sugar beet 
tolerances. Consequently, EPA will not take action to revoke the sugar 
beet tolerances in 40 CFR 180.242 at this time, but will follow-up with 
the registrant on amending the registration in order to delete the 
sugarbeet use and address the tolerances in a future publication in the 
Federal Register.
    10. Thidiazuron. Based on available processing data that show 
thidiazuron residues on cottonseed hulls concentrated slightly by a 
factor of 1.4x, EPA expects residues not to exceed the current 
recommended raw agricultural commodity tolerance of 0.3 ppm for 
cottonseed. Therefore, the tolerance on cottonseed hulls is no longer 
needed. Consequently, EPA is proposing to revoke the tolerance in 40 
CFR 180.403(a) on cotton, hulls.
    Cottonseed meal is a common feeding source for poultry. A 
cottonseed meal processing study at 5x application rate showed that 
thidiazuron residues were less than the LOQ (< 0.05 ppm) and did not 
concentrate, and EPA determined that there is no reasonable expectation 
of finite residues in poultry and eggs. Therefore, the tolerances on 
poultry fat, meat, meat byproducts, and egg are no longer needed under 
40 CFR 180.6(a)(3). Consequently, the Agency is proposing to revoke the 
tolerances in 40 CFR 180.403 for the combined residues of thidiazuron 
and its aniline containing metabolites in or on poultry, fat; poultry, 
meat; poultry, meat byproducts; and egg.
    Based on available data showing thidiazuron residues were as high 
as 0.21 ppm on cottonseed, EPA determined that the tolerance should be 
decreased from 0.4 to 0.3 ppm. Therefore, the Agency is proposing to 
decrease the tolerance in 40 CFR 180.403(a) on cotton, undelinted seed 
to 0.3 ppm.
    Pending storage stability and raw data to validate the ruminant 
feeding study, EPA determined that the tolerances for thidiazuron and 
its metabolites of concern are not expected to exceed 0.4 ppm for fat, 
meat, and meat byproducts, and therefore should be increased from 0.2 
to 0.4 ppm. Therefore, the Agency is proposing to increase the 
tolerances in 40 CFR 180.403(a) on cattle, fat; cattle, meat; cattle, 
meat byproducts; goat, fat; goat, meat; goat, meat byproducts; hog, 
fat; hog, meat; hog, meat byproducts; horse, fat; horse, meat; horse, 
meat byproducts; sheep, fat; sheep, meat; and sheep, meat byproducts to 
0.4 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 pestcide chemical residue.
    Based on available data that showed thidiazuron residues as high as 
22.12 ppm, EPA determined that a tolerance of 24.0 ppm should be 
established for cotton gin byproducts. Therefore, the Agency is 
proposing to establish a tolerance in 40 CFR 180.403(a) for the 
combined residues of thidiazuron and its aniline containing metabolites 
in or on cotton, gin byproducts at 24.0 ppm.
    There are no Codex MRLs for thidiazuron.
    11. Tribuphos. EPA is proposing to remove the ``negligible 
residue'' designation from all entries in 40 CFR 180.272 to conform to 
current Agency administrative practice.
    Based on the MTDB for cattle and available exaggerated ruminant 
feeding data (2.7x MTDB), tribuphos residues in milk and fat were 
expected by the Agency at 1x to be as high as 0.008 ppm and 0.13 ppm, 
respectively. Therefore, the Agency determined that the tolerance on 
milk should be increased from 0.002 ppm to the LOQ (0.01 ppm), and that 
tolerances on the fat of cattle, goats, and sheep should be increased 
from 0.02 to 0.15 ppm and tolerances on the fat of hogs and horses 
should be established at 0.15 ppm. Therefore, EPA is proposing in 40 
CFR 180.272 to increase tolerances on cattle, fat; goat, fat; and 
sheep, fat to 0.15 ppm; and establish tolerances on hog, fat and horse, 
fat at 0.15 ppm. Also, EPA is proposing in 40 CFR 180.272 to increase 
the tolerance on milk to 0.01 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.
    Based on the MTDB for cattle and available exaggerated ruminant 
feeding data (2.7x MTDB), tribuphos residues in meat and liver were 
expected by the Agency at 1x to be as high as 0.015 ppm and 0.019 ppm, 
respectively. Therefore, the Agency determined that the tolerances on 
meat and meat byproducts of hogs and horses should all be established 
at 0.02 ppm. Therefore, EPA is proposing in 40 CFR 180.272 to establish 
tolerances on hog, meat; hog, meat byproducts; horse, meat; and horse, 
meat byproducts at 0.02 ppm.
    Based on available data (where sites had a 7-day PHI, with the 
exception of one site with a 9-day PHI) that showed tribuphos residues 
as high as 36.39 ppm, EPA determined that a tolerance of 40.0 ppm 
should be established for cotton gin byproducts. Therefore, the Agency 
is proposing to establish a

[[Page 24208]]

tolerance in 40 CFR 180.272 on cotton, gin byproducts at 40.0 ppm.
    There are no Codex MRLs for tribuphos.

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 the 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 the 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 in follow-up to the 
tolerance recommendations made during the reregistration and tolerance 
reassessment processes (including follow-up on canceled or additional 
uses of pesticides). The safety finding determination under section 408 
of the FFDCA standard is discussed in detail in each Post-FQPA RED and 
TRED for the active ingredient. 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.
    EPA has issued post-FQPA REDs for chloroneb, cypermethrin, 
methidathion, nitrapyrin, oxyfluorfen, pirimiphos-methyl, 
thiabendazole, thidiazuron, and tribuphos, and a TRED for tebuthiuron, 
whose RED was completed prior to FQPA. A RED for sulfosate was not 
needed because it was registered after November 1, 1984 and not subject 
to reregistration eligibility, and its tolerances were reassessed prior 
to completion of a TRED, such that a TRED for sulfosate was no longer 
needed because EPA made a safety finding which reassessed its 
tolerances according to the FFDCA standard, maintaining them when new 
tolerances were established as noted in Unit II.A. REDs and TREDs 
contain the Agency's evaluation of the data base 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 the 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.
    EPA has developed guidance concerning submissions for import 
tolerance support (65 FR 35069, June 1, 2000) (FRL-6559-3). This 
guidance will be made available to interested persons. Electronic 
copies are available on the internet at http://www.epa.gov/. On the 

Home Page select ``Laws, Regulations, and Dockets,'' then select 
Regulations and Proposed Rules and then look up the entry for this 
document under ``Federal Register--Environmental Documents.'' You can 
also go directly to the ``Federal Register'' listings at http://www.epa.gov/fedrgstr/
.

    When EPA establishes tolerances for pesticide residues in or on raw 
agricultural commodities, consideration must be given to the possible 
residues of those chemicals in meat, milk, poultry, and/or eggs 
produced by animals that are fed agricultural products (for example, 
grain or hay) containing pesticides residues (40 CFR 180.6). When 
considering this possibility, EPA can conclude that:
    1. Finite residues will exist in meat, milk, poultry, and/or eggs.
    2. There is a reasonable expectation that finite residues will 
exist.

[[Page 24209]]

    3. There is a reasonable expectation that finite residues will not 
exist. If there is no reasonable expectation of finite pesticide 
residues in or on meat, milk, poultry, or eggs, tolerances do not need 
to be established for these commodities (40 CFR 180.6(b) and (c)).
    EPA has evaluated certain specific meat, milk, poultry, and egg 
tolerances proposed for revocation in this rule and has concluded that 
there is no reasonable expectation of finite pesticide residues of 
concern in or on those commodities.

C. When do These Actions Become Effective?

    With the exception of revocation of regional tolerances for 
methidathion on alfalfa forage, alfalfa hay, timothy forage, and 
timothy hay for which EPA is proposing specific expiration/revocation 
dates, the Agency is proposing that the actions herein become effective 
on the date of publication of the final rule in the Federal Register. 
With the exception of the revocation of these four regional tolerances 
for methidathion, 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 had sufficient time for passage through the channels 
of trade. EPA is proposing an expiration/revocation date of March 31, 
2008 for the methidathion tolerances on alfalfa forage, alfalfa hay, 
timothy forage, and timothy hay. The Agency believes that, because 
their regional registrations expire on December 31, 2007, the 
revocation date of March 31, 2008 allows sufficient time for passage of 
treated commodities through the channels of trade. However, 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 section, 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. Are the Proposed Actions Consistent with International 
Obligations?

    The tolerance actions in this proposal are not discriminatory and 
are designed to ensure that both domestically produced and imported 
foods meet the food safety standards established by the FFDCA. The same 
food safety standards apply to domestically produced and imported 
foods.
    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, as required by section 408(b)(4) 
of the FFDCA. 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 in a notice published 
for public comment. EPA's effort to harmonize with Codex MRLs is 
summarized in the tolerance reassessment section of individual REDs and 
TREDs, and in the Residue Chemistry document which supports the RED and 
TRED, as mentioned in Unit II.A. Specific tolerance actions in this 
rule and how they compare to Codex MRLs (if any) are discussed in Unit 
II.A.

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, 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) (Public Law 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), 
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 action 
will

[[Page 24210]]

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 the 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 6, 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.
