II. Background

A. What Action is the Agency Taking?

    In the Federal Register of September 20, 2006 (71 FR 54953) (FRL-
8078-2), EPA issued a proposed rule to revoke, remove, modify, and 
establish certain tolerances and/or tolerance exemption for residues 
for the herbicides chlorpropham, linuron, asulam and pebulate and the 
fungicide thiophanate-methyl. Also, the proposal of September 20, 2006 
(71 FR 54953) (FRL-8078-2) provided a 60-day comment period which 
invited public comment for consideration and for support of tolerance 
retention under the Federal Food, Drug, and Cosmetic Act (FFDCA) 
standards.
    EPA is revoking, removing, modifying, and establishing specific 
tolerances for residues of the herbicides chlorpropham, linuron, asulam 
and pebulate and the fungicide thiophanate-methyl in or on commodities 
listed in the regulatory text.
    EPA is finalizing these tolerance actions in order to implement the 
tolerance recommendations made during the reregistration and tolerance 
reassessment processes (including follow-up on canceled or additional 
uses of pesticides). As part of the reregistration and tolerance 
reassessment processes, EPA is required to determine whether each of 
the amended tolerances meets the safety standards under the FQPA. The 
safety finding determination of ``reasonable certainty of no harm'' is 
found in detail in each Reregistration Eligibility Decision (RED) and 
Report on FQPA Tolerance Reassessment Progress and Interim Risk 
Management Decision (TRED) for the active ingredient. REDs and TREDs 
recommend certain tolerance actions to be implemented to reflect 
current use patterns, to meet safety findings and change commodity 
names and groupings in accordance with new EPA policy. Printed copies 
of 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 https://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 https://
www.ntis.gov. Electronic copies of REDs and TREDs are available on the 
internet at https://www.epa.gov/pesticides/reregistration/status.htm.
    In this final rule, EPA is revoking certain tolerances and 
tolerance exemptions because these specific tolerances and exemptions 
correspond to uses no longer current or registered under FIFRA in the 
United States. The tolerances revoked by this final rule are no longer 
necessary to cover residues of the relevant pesticides in or on 
domestically treated commodities or commodities treated outside but 
imported into the United States. It is EPA's general practice to revoke 
those tolerances and tolerance exemptions for residues of pesticide 
active ingredients on crop uses for which there are no active 
registrations under FIFRA, unless any person in comments on the 
proposal indicates a need for the tolerance or tolerance exemption to 
cover residues in or on imported commodities or domestic commodities 
legally treated.
    EPA's policy is to issue a final rule revoking those tolerances for 
residues of pesticide chemicals for which there are no active 
registrations under FIFRA, unless any person commenting on the proposal 
demonstrates a need for the tolerance to cover residues in or on 
imported commodities or domestic commodities legally treated.
    Generally, EPA will proceed with the revocation of these tolerances 
on the grounds discussed in Unit II.A. if one of the following 
conditions applies:
    1. Prior to EPA's issuance of a section 408(f) order requesting 
additional data or issuance of a section 408(d) or (e) order revoking 
the tolerances on other grounds, commenters retract the comment 
identifying a need for the tolerance to be retained.
    2. EPA independently verifies that the tolerance is no longer 
needed.
    3. The tolerance is not supported by data that demonstrate that the 
tolerance meets the requirements under FQPA.
    This final rule does not revoke those tolerances for which EPA 
received comments stating a need for the tolerance to be retained. In 
response to the proposal published in the Federal Register of September 
20, 2006 (71 FR 54953) (FRL-8078-2), EPA received two comments during 
the 60-day public comment period, as follows:
    Comment. A comment was received from a private citizen that 
expressed concern with pesticide residues in general and that pesticide 
residue levels should be zero. Concern was also expressed for the 
number of chemicals found in the bodies of adults and children.
    Agency response. The private citizen's comment did not take issue 
with the Agency's conclusion that certain tolerances should be revoked, 
established and modified. The Agency conducts a detailed risk 
assessment to determine whether establishing and/or increasing 
tolerances is safe; i.e., there is a reasonable certainty that no harm 
will result from aggregate exposure to the pesticide chemical residue. 
Also, it is EPA's general practice to propose revocation of tolerances 
for residues of pesticide active ingredients on crop uses for which 
FIFRA registrations no longer exist.
    Comment. Cerexagri, Inc. commented that the term postharvest 
associated with the tolerances for thiophanate-methyl residues of 
concern on apple, apricot, cherry, peach and plum is not appropriate 
because the use patterns are based on pre-harvest applications. 
Cerexagri, Inc. also took issue with the increase of the tolerance for 
thiophanate-methyl residues of concern on canola at 0.1 parts per 
million (ppm) to 0.2 ppm. They cited data and analytical methods which 
indicate the tolerance increase is not appropriate.
    Agency response. The thiophanate-methyl Residue Chemistry Chapter 
and RED included recommendations that certain tolerances be designated 
as postharvest. The Agency agrees that the uses of thiophanate-methyl 
include pre-harvest applications such that the post-harvest designation 
is not appropriate.

[[Page 37648]]

Therefore, the Agency has determined that the postharvest designation 
should not be linked to the tolerances in the 40 CFR. Therefore, EPA is 
removing the references to ``postharvest'' from the tolerances in 40 
CFR 180.371. Cerexagri, Inc, also commented on the proposed tolerance 
level increase for canola from 0.1 to 0.2 ppm.
    Setting the tolerance on canola at 0.2 ppm was recommended in the 
thiophanate-methyl RED based on an enforcement method limit of 
quantitation (LOQ) of 0.05 ppm. Crexagri believes that the tolerance on 
canola should remain at 0.1 ppm, the current tolerance level, based on 
an appropriate enforcement method LOQ of 0.025 ppm. The field trial 
data showed non-detectable residues of thiophanate-methyl and one 
sample with detection equivalent to 0.018 ppm of the metabolite methyl 
2-benzimidazolyl carbamate (MBC). Later, Cerexagri submitted an 
addendum to the crop field trial data which details an estimation of a 
practical limit of detection (LOD) of 0.005 ppm in/on canola seed for 
MBC. The Agency believes that a viable LOQ is usually about 3x the 
method LOD, and therefore, an LOD would correspond to about a 0.015 ppm 
for the method. Consequently, the Agency believes that an LOD of 0.025 
ppm is a conservative estimate. Based on the estimated method LOQ for 
the metabolite MBC, the Agency agrees that the canola seed tolerance 
should remain at 0.1 ppm in 40 CFR 180.371(c).
    1. Chlorpropham. A plant commodity tolerance on potato for 
chlorpropham is currently regulated for residues of CIPC (isopropyl m-
chlorocarbanilate) and its metabolite 1-hydroxy-2-propyl 3'-
chlorocarbanilate (calculated as CIPC) in 40 CFR 180.181. Because the 
regulated metabolite was not detected in potato following treatment 
with radiolabelled 14C-chlorpropham, EPA determined that the tolerance 
expression for plants should be expressed in terms of chlorpropham per 
se. Meanwhile, the current interim milk and livestock tolerances in 40 
CFR 180.319 are regulated for isopropyl m-chlorocarbanilate (CIPC) 
residues. However, based on available ruminant data that show residues 
of chlorpropham and its metabolite 4-hydroxychlorpropham-O-sulfonic 
acid (4-HSA) in milk and edible tissues, EPA determined that the 
tolerance expression should be expressed in terms of the combined 
residues of chlorpropham and 4-hydroxychlorpropham-O-sulfonic acid (4-
HSA) and recodified under 40 CFR 180.181 as permanent tolerances. 
Therefore, EPA is recodifying plant tolerances for chlorpropham from 40 
CFR 180.181(a) to (a)(1) and regulate the plant regulator and herbicide 
chlorpropham (isopropyl m-chlorocarbanilate (CIPC) in plants. Also, EPA 
is removing the interim milk and livestock tolerances (meat, fat, and 
meat byproducts of cattle, hog, horse, goat, and sheep) for 
chlorpropham in 40 CFR 180.319, recodify them as permanent tolerances 
in 40 CFR 180.181(a)(2) and regulate tolerances there for the plant 
growth regulator and herbicide chlorpropham (isopropyl m-
chlorocarbanilate [CIPC]) and its metabolite 4-hydroxychlorpropham-O-
sulfonic acid (4-HSA).
    In addition, based on ruminant feeding data and the calculated 
maximum theoretical dietary burden (MTDB) estimates, EPA determined 
that tolerances on the meat of cattle, hog, horse, goat, and sheep 
should be increased from 0.05 to 0.06 parts per million (ppm), the 
limit of quantitation (LOQ). Also, based on exaggerated feeding study 
data that showed combined residues of concern in kidney at about 0.3 
ppm, the Agency determined that tolerances for kidney of cattle, hog, 
horse, goat, and sheep should be separated from their existing meat 
byproduct tolerances at 0.05 ppm and increased to 0.30 ppm. Since the 
combined residues of concern were shown to be near or below the LOQ 
(0.06 ppm), the Agency determined that tolerances for meat byproducts, 
except kidney of cattle, hog, horse, goat, and sheep should be 
increased from 0.05 to 0.06 ppm. In addition, based on ruminant feeding 
data that showed combined residues of concern in fat at 0.17 ppm, the 
Agency determined that tolerances for the fat of cattle, hog, horse, 
goat, and sheep should be increased from 0.05 to 0.20 ppm. Moreover, 
based on ruminant feeding data and the maximum tolerated dietary burden 
(MTDB) burden estimates that showed combined residues of concern to be 
0.25 ppm, the Agency determined that the tolerance for milk should be 
increased from 0.05 to 0.30 ppm. Therefore, EPA is increasing 
tolerances in newly recodified 40 CFR 180.181(a)(2) for the combined 
residues of chlorpropham and 4-hydroxychlorpropham-O-sulfonic acid (4-
HSA) as follows: Milk from 0.05 to 0.30 ppm; cattle, fat; hog, fat; 
horse, fat; goat, fat; and sheep, fat from 0.05 to 0.20 ppm; cattle, 
meat; hog, meat; horse, meat; goat, meat; and sheep, meat from 0.05 to 
0.06 ppm; cattle, meat byproducts, except kidney; hog, meat byproducts, 
except kidney; horse, meat byproducts, except kidney; goat, meat 
byproducts, except kidney; and sheep, meat byproducts, except kidney 
from 0.05 to 0.06 ppm; and cattle, kidney; hog, kidney; horse, kidney; 
goat, kidney; and sheep, kidney from 0.05 to 0.30 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 available potato field trial data that show chlorpropham 
residues as high as 24 ppm, the Agency determined that the tolerance in 
newly recodified 40 CFR 180.181(a)(1) should be decreased from 50 to 30 
ppm. The term ``postharvest'' associating these tolerances with the 
timing of the use is being removed, since the enforcement Agency would 
not know whether a commodity bore residues resulting from postharvest 
treatment. Therefore, EPA is decreasing the tolerance in newly 
recodified 40 CFR 180.181(a)(1) in or on potato, postharvest from 50 to 
30 ppm and revising potato, postharvest to potato.
    Based on available potato processing data that demonstrate an 
average concentration factor of chlorpropham residues at 3X, and the 
highest average field trial (HAFT) whole potato residue of 12.0 ppm, 
the Agency determined that residues in the wet potato peel would be 36 
ppm; therefore, a tolerance should be established on potato, wet peel 
at 40 ppm. (Residues did not concentrate in potato granules, flakes or 
chips.) Therefore, EPA is establishing a tolerance in newly recodified 
40 CFR 180.181(a)(1) for the chlorpropham residues of concern or on 
potato, wet peel at 40 ppm.
    2. Linuron. According to the TRED, the tolerance expression, which 
is currently expressed as ``residues of the herbicide linuron (3-(3,4-
dichlorophenyl)-1-methoxy-1-methylurea)'' in 40 CFR 180.184(a) and (c), 
should be modified to include metabolites that can be converted to 3,4-
dichloroaniline that are of toxicological concern. Consequently, EPA is 
establishing the tolerance expression in 40 CFR 180.184(a) to regulate 
the combined residues of the herbicide linuron (3-(3,4-dichlorophenyl)-
1-methoxy-1-methylurea) and its metabolites convertible to 3,4-
dichloroaniline, calculated as linuron in/on food commodities and in 40 
CFR 180.184(c) to regulate the combined residues of the herbicide 
linuron (3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea) and its 
metabolites convertible to 3,4-dichloroaniline, calculated as linuron 
in/on food commodities.

[[Page 37649]]

    The feeding of treated soybean forage or hay to livestock is 
prohibited as stated on the registration labels and therefore, the 
tolerances are no longer needed. Consequently, EPA is revoking the 
tolerances in 40 CFR 180.184(a) soybean, forage and soybean, hay.
    Based on field trial data that indicate linuron residues of concern 
in or on field corn stover are as high as 5.5 ppm, the Agency 
determined that a tolerance should be 6.0 ppm on corn, field, stover. 
The RED indicates a data deficiency for corn, sweet, stover; however, 
the field corn stover data can be translated to sweet corn stover, 
therefore, the Agency has determined the tolerance for corn, sweet, 
stover can be increased from 1.0 to 6.0 ppm. Therefore, EPA is 
increasing the tolerance in 40 CFR 180.184(a) for the combined residues 
of the herbicide linuron and its metabolites convertible to 3,4-
dichloroaniline, calculated as linuron in or on corn, field, stover and 
corn, sweet, stover from 1.0 to 6.0 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.
    In order to conform to current Agency practice, EPA is revising the 
commodity terminology in 40 CFR 180.184(a) for corn, grain (inc. pop) 
at 0.25 ppm into corn, field, grain and corn, pop, grain. However, 
because there are no active U.S. registrations for the use of linuron 
on popcorn, the tolerance is no longer needed and should be revoked. 
Therefore, EPA is revoking the tolerance in 40 CFR 180.184(a) on corn, 
pop, grain. In addition, based on field trial data that indicate 
linuron residues of concern in or on corn grain as high as 0.06 ppm, 
the Agency determined that the corn, field, grain tolerance should be 
decreased from 0.25 to 0.1 ppm. Therefore, EPA is decreasing the 
tolerance in 40 CFR 180.184(a) for the combined residues of the 
herbicide linuron and its metabolites convertible to 3,4-
dichloroaniline, calculated as linuron in or on corn, field, grain from 
0.25 to 0.1 ppm.
    Ruminant feeding data at an exaggerated level (6.9x) show that 
linuron residues of concern expected at a 1x feeding level are 0.16 ppm 
in fat, 0.07 ppm in meat, 1.9 ppm in liver and kidney, and 0.05 ppm in 
milk. Based on these expected residue levels, the Agency determined 
that the tolerances for the fat of cattle, goat, horse and sheep should 
be decreased from 1.0 to 0.2 ppm; meat tolerances of cattle, goat, 
horse and sheep should be decreased from 1.0 to 0.1 ppm; meat byproduct 
tolerances of cattle, goat, horse, and sheep should be separated into 
tolerances for meat byproducts, except kidney and liver, and decreased 
from 1.0 to 0.1 ppm; kidney of cattle, goat, horse, and sheep, which 
should be established separately and increased from 1.0 to 2.0 ppm; 
liver of cattle, goat, horse, and sheep, which should be established 
separately and increased from 1.0 to 2.0 ppm; and a tolerance for milk 
should be established at 0.05 ppm. Therefore, EPA is decreasing 
tolerances from 1.0 ppm in 40 CFR 180.184(a) for the following: Cattle, 
fat; goat, fat; horse, fat; and sheep, fat; each to 0.2 ppm; cattle, 
meat; cattle, meat byproducts, except kidney and liver; goat, meat; 
goat, meat byproducts, except kidney and liver; horse, meat; horse, 
meat byproducts, except, kidney and liver; sheep, meat and sheep, meat 
byproducts, except kidney and liver; each from 1.0 ppm to 0.1 ppm. 
Also, EPA is establishing separate tolerances in 40 CFR 180.184(a) for 
the following commodities: Cattle, kidney; cattle, liver; goat, kidney; 
goat, liver; horse, kidney; horse, liver; sheep, kidney; and sheep, 
liver; each at 2.0 ppm. In addition, EPA is establishing a tolerance in 
40 CFR 180.184(a) in milk at 0.05 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 ruminant feeding data and an estimated dietary burden in 
swine that is much less than that for beef and dairy cattle, the Agency 
calculated likely linuron residues of concern to be less than 0.007 ppm 
in hog fat, 0.003 ppm in hog meat, and 0.08 ppm in hog liver and 
kidney; therefore, the Agency determined the tolerances should be 
decreased to 0.05 ppm, 0.05 ppm and 0.1 ppm for hog fat, hog meat and 
hog meat byproducts, respectively. Therefore, EPA is decreasing 
tolerances in 40 CFR 180.184(a) for the combined residues of the 
herbicide linuron and its metabolites convertible to 3,4-
dichloroaniline, calculated as linuron in or on hog, fat and hog, meat 
from 1.0 to 0.05 ppm; and hog, meat byproducts from 1.0 to 0.1 ppm.
    Based on field trial data, the Agency determined that linuron 
residues of concern were non-detectable (<0.05 ppm) in or on parsnips. 
Therefore, EPA is decreasing the tolerance in 40 CFR 180.184(a) for the 
combined residues of the herbicide linuron and its metabolites 
convertible to 3,4-dichloroaniline, calculated as linuron in or on 
parsnip (with or without tops) from 0.5 to 0.05 ppm and revising the 
commodity terminology to parsnip, roots and parsnip, tops.
    Since completion of the Linuron TRED, data deficiencies for cotton 
gin byproducts have been adequately addressed. Based on more recent 
cotton storage stability and field trial data reflecting all cotton 
growing regions of the U.S. submitted in response to the TRED, the 
maximum residues of linuron in or on stripper cotton gin byproducts 
were 3.32 ppm, the Agency determined that the tolerance should be 
established for cotton gin byproducts at 5.0 ppm. Therefore, EPA is 
establishing a tolerance in 40 CFR 180.184(a) for the combined residues 
of the herbicide linuron and its metabolites convertible to 3,4-
dichloroaniline, calculated as linuron in or on cotton, gin byproducts 
at 5.0 ppm.
    Because use of linuron on potatoes and celery is restricted to east 
of the Rocky Mountains, and use on wheat is restricted to the states of 
Idaho, Oregon, and Washington, the Agency determined that tolerances on 
celery, potato, and the forage, grain, hay and straw of wheat should be 
recodified as regional registrations. Also, based on field trial data 
that indicate combined linuron residues of concern were nondetectable 
(<0.05 ppm) in or on all but one sample (0.07 ppm) of potato, 
nondetectable (<0.03 ppm) in or on wheat grain, and as high as 2.0 ppm 
in or on wheat straw, the Agency determined that the tolerances should 
be decreased from 1.0 to 0.2 ppm on potato and from 0.25 to 0.05 ppm on 
wheat, grain, and increased to 0.5 to 2.0 ppm on wheat straw. 
Therefore, EPA is recodifying tolerances on celery, potato, and the 
forage, grain, hay and straw of wheat from 40 CFR 180.184(a) to (c) for 
the combined residues of the herbicide linuron and its metabolites 
convertible to 3,4-dichloroaniline, calculated as linuron as follows: 
Potato decreased from 1.0 to 0.2 ppm; wheat, grain decreased from 0.25 
to 0.05 ppm; and wheat, straw increased from 0.5 to 2.0 ppm and 
correcting 180.1(N) to 180.1(M). 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.
    Interregional Research Project 4 (IR-4) has submitted 
petitions (PP 8E5027 and PP 8E5028) requesting the establishment of 
tolerances on celeriac and rhubarb based on use directions and data 
translated from carrots and celery, respectively. Based on field trial 
data that show linuron residues of concern for carrot samples treated 
at 0.75X were as high as 0.56 ppm and celery samples treated at 1X were 
as high as 0.42 ppm, the Agency determined that tolerances should be 
established at 1.0 ppm on

[[Page 37650]]

celeriac and 0.5 ppm on rhubarb. Therefore, EPA is establishing 
tolerances in 40 CFR 180.184(a) for the combined residues of the 
herbicide linuron and its metabolites convertible to 3,4-
dichloroaniline, calculated as linuron in or on celeriac at 1.0 ppm and 
rhubarb at 0.5 ppm.
    Although additional data are anticipated in 2007 in response to the 
TRED, tolerances associated with sorghum and sweet corn have been 
reassessed at the current tolerance levels. The Agency determined that 
the tolerances are safe; i.e. there is a reasonable certainty that no 
harm will result from aggregate exposure to the pesticide chemical 
residues. EPA is maintaining the tolerance level and revising the 
commodity terminology in 40 CFR 180.184(a) to conform to current Agency 
practice as follows: ``Sorghum, forage'' to ``sorghum, grain, forage'' 
at 1.0 ppm; ``corn, fresh (inc. sweet, kernel plus cob with husks 
removed)'' to ``corn, sweet, kernel plus cob with husks removed'' at 
0.25 ppm; and splitting ``soybean, (dry or succulent)'' to separate 
tolerances fo ``soybean, seed'' and ``soybean, vegetable'' both at 1.0 
ppm.
    3. Pebulate. The last U.S. registration was cancelled October 24, 
2003 due to non-payment of registration fees and a notice was published 
in the Federal Register on November 6, 2003 (68 FR 62785, FRL-7331-3). 
Therefore, tolerances are no longer needed and EPA is revoking the 
tolerances in 40 CFR 180.238 for residues of pebulate (S-propyl 
butylethylthiocarbamate) in or on beet, sugar roots; beet sugar, tops; 
and tomato.
    4. Asulam. The tolerance expression in 40 CFR 180.360 currently 
regulates asulam (methyl sulfanilylcarbamate) per se. The Agency 
recommended in the asulam TRED that the tolerance expression be revised 
to include metabolites containing the sulfanilamide moiety because in 
the absence of toxicological data the Agency assumed these compounds to 
be potentially comparable in toxicity to the parent compound, asulam. 
Therefore, EPA is revising the tolerance expression in 40 CFR 180.360 
to read as follows: ``(a) General. Tolerances are established for the 
combined residues of asulam (methyl sulfanilylcarbamate) and its 
metabolites containing the sulfanilamide moiety in or on the following 
food commodities.''
    Based on field trial data that showed asulam residues of concern as 
high as 0.23 ppm and a correction for a 70% loss of residues during 
storage, the Agency calculated that the maximum residue should be 0.71 
ppm, and determined that the tolerance on sugarcane should be increased 
form 0.1 to 1.0 ppm. Therefore, EPA is increasing the tolerance in 40 
CFR 180.360(a) for the combined residues of asulam and its metabolites 
containing the sulfanilamide moiety in or on sugarcane, cane from 
0.1(N) to 1.0 ppm. The Agency is removing the ``N'' (negligible 
residues) to conform to current Agency Administrative practice. The 
Agency determined that the increased tolerance is safe; i.e. there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue.
    Based on available sugarcane processing data that show an average 
concentration factor of asulam residues at 48x and a HAFT residue value 
that when corrected for a 70% loss in storage is expected to be 0.557 
ppm (0.167 ppm/0.3), the Agency calculated that the residues would be 
about 26.7 ppm and determined a tolerance should be established for 
sugarcane molasses at 30 ppm. Therefore, EPA is establishing a 
tolerance in 40 CFR 180.360(a) for the combined residues of asulam and 
its metabolites containing the sulfanilamide moiety in or on sugarcane, 
molasses at 30 ppm.
    Based on a 1.2x exaggerated feeding study, animal metabolism data 
and a ruminant diet containing 10% molasses (a livestock feed item), 
the Agency determined that because the anticipated residues of asulam 
and sulfanilamide containing metabolites in milk are <0.025 ppm, in/on 
fat, liver, and muscle are <0.05 ppm, and kidney is 0.12 ppm, that 
tolerances should be established in milk, and on the fat and meat of 
cattle, goats, hogs, horses, and sheep at 0.05 ppm, and meat byproducts 
of cattle, goats, hogs, horses, and sheep at 0.2 ppm. Therefore, EPA is 
establishing tolerances in 40 CFR 180.360(a) for the combined residues 
of asulam and its metabolites containing the sulfanilamide moiety in/on 
commodities, as follows: Cattle, fat; goat, fat; hog, fat; horse, fat; 
and sheep, fat; cattle, meat; goat, meat; hog, meat; horse, meat; and 
sheep, meat at 0.05 ppm; and cattle, meat byproducts; goat, meat 
byproducts; hog, meat byproducts; horse, meat byproducts; and sheep, 
meat byproducts at 0.2 ppm; and milk at 0.05 ppm.
    5. Thiophanate-methyl. Currently, the tolerances for thiophanate-
methyl are expressed in 40 CFR 180.371(a) in terms of thiophanate-
methyl(dimethyl regulates thiophanate-methyl and its oxygen analogue 
dimethyl-4,4-o-phenylenebis(allophonate), and its benzimidazole-
containing metabolites (calculated as thiophanate-methyl); and in 40 
CFR 180.371(b) and (c) in terms of thiophanate-methyl and its 
metabolite (methyl 2-benzimidazoyl carbamate (MBC)). The Agency has 
determined that the residues of concern for plant and animal 
commodities for tolerance enforcement consists of the parent and its 
metabolite methyl 2-benzimidazolyl carbamate (MBC). Therefore, EPA is 
amending the tolerance expression in 40 CFR 180.371(a), (b), and (c) so 
as to regulate tolerances for the combined residues of thiophanate-
methyl (dimethyl[(1,2-phenylene) bis(iminocarbonothioyl)] 
bis(carbamate)) and its metabolite methyl 2-benzimidazoyl carbamate 
(MBC), calculated as thiophanate-methyl in/on food commodities.
    EPA no longer considers dry apple pomace, banana pulp, and bean 
forage and hay, and peanut forage to be significant animal feed items 
and tolerances are no longer needed (A listing of significant food and 
feed commodities is found in ``Table 1.--Raw Agricultural and Processed 
Commodities and Feedstuffs Derived from Crops'' which is found in 
Residue Chemistry Test Guidelines OPPTS 860.1000 dated August 1996, 
available athttps://www.epa.gov/opptsfrs/publications/OPPTS_Harmonized/
860_Residue_Chemistry_Test_Guidelines/Series/). Currently, there is 
a tolerance in 40 CFR 180.371 on peanut (forage and hay). Based on 
field trial data that show thiophanate-methyl residues of concern as 
high as 3.76 ppm, the Agency has determined that the tolerance on 
peanut hay should be decreased from 15.0 to 5.0 ppm. In addition, 
thiophanate-methyl registrations were approved by EPA to be amended to 
delete use on celery by request of the registrant in 1997 (62 FR 67365, 
FRL-5761-8). Therefore, EPA is revoking the tolerances in 40 CFR 
180.371(a) on apple, dry pomace; banana, pulp; bean (forage and hay), 
and celery, and revise the commodity terminology from peanut (forage 
and hay) into separate tolerance for peanut, forage and peanut, hay, 
and revoke peanut forage, and decrease peanut, hay from 15.0 to 5.0 
ppm.
    Based on available exaggerated (10x) poultry feeding data, EPA 
determined that there is no reasonable expectation of finite 
thiophanate-methyl residues of concern in poultry commodities and 
therefore, the tolerance for egg (the only existing poultry commodity 
tolerance) is no longer needed under 40 CFR 180.6(a)(3). Therefore, EPA 
is revoking the tolerance in 40 CFR 180.371 for egg.
    Based on the available ruminant feeding study, the Agency 
determined that the thiophanate-methyl residues of

[[Page 37651]]

concern in milk and animal tissues were at the combined limit of 
quantitations (LOQs) of 0.05 ppm. Therefore, the tolerances for the 
milk and fat, meat and meat byproducts of cattle, goat, horse, and 
sheep should be increased to 0.15 ppm. Since the tolerance should be 
0.15 ppm for all meat byproducts which includes liver and kidney 
tissues, the tolerances should be revised from ``meat byproducts, 
except liver and kidney'' to ``meat byproducts'' and the tolerances for 
``horse, liver'' and ``cattle, goat, and sheep liver and kidney'' 
should be removed. Further, the Agency is removing the ``(N)'' 
(negligible residues) designation to conform to current Agency 
administrative practice. Therefore, EPA is increasing the tolerances in 
40 CFR 180.371 for the combined residues of thiophanate-methyl and 
methyl 2-benzimidazolyl carbamate in or on milk from 0.1 to 0.15 ppm; 
cattle, goats, horses, and sheep meat and fat from 0.1(N) to 0.15 ppm; 
revising ``cattle, goats, and sheep meat byproducts, except liver and 
kidney at 0.1(N)'' and ``horse, meat byproducts, except liver at 
0.1(N)'' to ``cattle, goats, horses, and sheep meat byproducts at 0.15 
ppm''; and removing cattle, goats, and sheep liver each at 2.5 ppm; 
horse, liver at 1.0 ppm; cattle, kidney at 0.2(N) ppm; and goat and 
sheep kidney each at 0.2 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 show thiophanate-methyl residues of 
concern as high as 16.25 ppm in/on tart and sweet cherries, 6.22 ppm on 
strawberries, less than the LOQ (<0.1 ppm) on wheat, the Agency 
determined that the tolerances should be increased on cherries from 
15.0 to 20.0, on strawberries from 5.0 to 7.0 ppm, and on wheat, grain 
from 0.05 to 0.1 ppm. Therefore, EPA is increasing and revising the 
tolerances in 40 CFR 180.371(a) for the combined residues of 
thiophanate-methyl and methyl 2-benzimidazolyl carbamate in/on cherry, 
postharvest at 15.0 to cherry, sweet and cherry, tart at 20.0 ppm, 
strawberry from 5.0 to 7.0 ppm, and wheat, grain from 0.05 to 0.1 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 the available field trial data that indicate thiophanate-
methyl and methyl 2-benzimidazolyl carbamate residues of concern were 
less than 2.0 ppm in/on apples, less than the combined LOQs (<0.1 ppm 
each) in/on almond nutmeat and as high as 0.49 ppm in/on almond hulls, 
<0.1 ppm in/on pecans and peanut nutmeat, as high as 0.19 ppm in/on dry 
beans (as high as 1.43 ppm on snap beans), as high as 2.55 ppm in/on 
peaches, and less than 0.5 ppm in/on plums, the Agency determined that 
established tolerances should be decreased for apples; almonds; almond, 
hulls; dry beans; peaches; peanuts; peanut hay; pecans; and plums. 
Therefore, EPA is decreasing the tolerances in 40 CFR 180.371(a) for 
the combined residues of thiophanate-methyl and methyl 2-benzimidazolyl 
carbamate in/on apple, postharvest from 7.0 to 2.0 ppm; almond from 
0.2(N) to 0.1 ppm; almond, hulls from 1.0 to 0.5 ppm; dry, beans from 
2.0 to 0.2 ppm and revise the commodity terminology from bean (snap and 
dry) to bean, snap, succulent at 0.2 ppm and bean, dry, seed at 0.2 
ppm; peach, postharvest from 15.0 to 3.0 ppm; peanut from 0.2(N) to 0.1 
ppm; pecans from 0.2 ppm to 0.1 ppm, and revise the commodity 
terminology from plum, postharvest from 15.0 to 0.5 ppm.
    In accordance with 40 CFR 180.1(h), residues in/on nectarines are 
covered by the reassessed tolerance on peaches, and therefore the 
tolerance on postharvest nectarines is no longer needed. Therefore, EPA 
is proposing to remove the tolerance in 40 CFR 180.371(a) on nectarine, 
postharvest.
    Based on plum processing data form plums treated at 10x that show 
thiophanate-methyl residues of concern do not concentrate in prunes, 
the Agency determined that the tolerance on plum, prune, postharvest is 
no longer needed since residues in/on prunes would be covered by the 
reassessed tolerance on plum, postharvest at 0.5 ppm. Therefore, EPA is 
removing the tolerance in 40 CFR 180.371(a) on plum, prune, 
postharvest.
    Based on field trial data that show thiophanate-methyl residues of 
concern in or on dry bulb onions as high as 0.30 ppm, the Agency 
determined that the tolerance onion, dry should be decreased from 3.00 
to 0.5 ppm and residues on garlic are covered by the bulb onion 
tolerance in accordance with 40 CFR 180.1(h). EPA is decreasing the 
tolerance in 40 CFR 180.371 for the combined thiophanate-methyl 
residues of concern in/on onion, dry from 3.0 to 0.5 ppm and revising 
the term to onion, bulb.
    Based upon the HAFT residues of 0.2 ppm in/on soybeans and the 
observed 6.5X concentration factor for hulls, the Agency determined 
that a separate tolerance should be established on soybean hulls at 1.5 
ppm. Therefore, EPA is establishing a tolerance in 40 CFR 180.371(a) 
for the combined residues of thiophanate-methyl and methyl 2-
benzimidazolyl carbamate in/on soybean, hulls at 1.5 ppm.
    The available field trial residue data in/on cucumbers, melons, 
pumpkins, and squash are adequate to support a cucurbit vegetable group 
9 tolerance at 1.0 ppm. Because a crop group tolerance covers all of 
the cucurbit vegetables, individual tolerances are no longer needed. 
Therefore, EPA is removing the individual tolerances in 40 CFR 
180.371(a) in/on cucumber, melon, pumpkin, and squash at 1.0 ppm, and 
combining them into a crop group tolerance on vegetable, cucurbit, 
group 9 at 1.0 ppm.
    As discussed in the comments in Unit II.A., the thiophanate-methyl 
Residue Chemistry Chapter and RED included recommendations that certain 
tolerances be designated as postharvest when the use is not solely 
postharvest. Therefore, the term postharvest should be removed. The 
Agency has determined that timings of treatment should not be included 
as part of these tolerances because a tolerance enforcement agency 
collecting and analyzing samples wouldn't know whether a commodity bore 
residues resulting from a seed treatment. The Agency is revising 
commodity terminology to conform to current Agency practice. Therefore, 
EPA is revising tolerances in 40 CFR 180.371(a) as follows: ``Apple, 
postharvest'' to ``apple;'' ``apricot, postharvest'' to ``apricot;'' 
``cherry, postharvest'' to ``cherry;'' ``peach, postharvest'' to 
``peach;'' ``plum, postharvest'' to ``plum;'' ``sugar beet, roots'' to 
``beet, sugar, roots;'' ``sugar beet, tops'' to ``beet, sugar, tops;'' 
``soybean'' to ``soybean, seed;'' ``sugarcane, seed piece treatment 
PRE-H'' to ``sugarcane, cane'' and in 40 CFR 180.371(b) from ``cotton'' 
to ``cotton, undelinted seed.''

B. What is the Agency's Authority for Taking this Action?

    EPA may issue a regulation establishing, modifying, or revoking a 
tolerance under section 408(e) of FFDCA. In this final rule, EPA is 
establishing, modifying, and revoking tolerances to implement the 
tolerance recommendations made during the reregistration and tolerance 
reassessment processes, and as follow-up on canceled uses of 
pesticides. As part of these processes, EPA is required to determine 
whether each of the amended tolerances meets the safety standards under 
the Food Quality Protection Act (FQPA). The safety finding 
determination is found in detail

[[Page 37652]]

in each Reregistration Eligibility Document (RED) and Tolerance 
Reassessment Document (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 pebulate and thiophanate-methyl 
and TREDs for chlorpropham, linuron, and asulam, which had REDs 
completed prior to FQPA. REDs and TREDs contain the Agency's evaluation 
of the data base for these pesticides, including statements regarding 
additional data on the active ingredients that may be needed to confirm 
the potential human health and environmental risk assessments 
associated with current product uses, and 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 FQPA standard of 
``reasonable certainty of no harm.'' However, tolerance revocations 
recommended in REDs and TREDs that are made final in this document do 
not need such assessment when the tolerances are no longer necessary.
    EPA's general practice is to revoke 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. 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.
    When EPA establishes tolerances for pesticide residues in or on raw 
agricultural commodities, the Agency gives consideration to possible 
pesticide residues 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). If there is no 
reasonable expectation of finite pesticide residues in or on meat, 
milk, poultry, or eggs, then tolerances do not need to be established 
for these commodities (40 CFR 180.6(b) and 180.6(c)).

C. When Do These Actions Become Effective?

    These actions become effective on the date of publication of this 
final rule in the Federal Register because their associated uses have 
been canceled for several years. The Agency believes that treated 
commodities have had sufficient time for passage through the channels 
of trade.
    Any commodities listed in the regulatory text of this document that 
are treated with the pesticides subject to this final rule, and that 
are in the channels of trade following the tolerance revocations, shall 
be subject to section 408(1)(5) of FFDCA, as established by the 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 that the 
pesticide was applied to such food.

III. Are There Any International Trade Issues Raised by this Final 
Action?

    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 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, section 408(b)(4) of FFDCA 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 the proposed rule cited in Unit II.A.

IV. Statutory and Executive Order Reviews

    In this final rule EPA establishes tolerances under section 408(e) 
of FFDCA, and also modifies and revokes specific tolerances established 
under section 408 of FFDCA. The Office of Management and Budget (OMB) 
has exempted these types of actions (i.e., 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 rule has been exempted from review under 
Executive Order 12866 due to its lack of significance, this 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 final 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 104-13, 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,

[[Page 37653]]

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 rule, the Agency hereby certifies that this final rule will not 
have a significant 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 pesticides named in 
this final rule, the Agency knows of no extraordinary circumstances 
that exist as to the present revocations that would change EPA's 
previous analysis. 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 final 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 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 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 rule.

V. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report to each House of the Congress and to 
the Comptroller General of the United States. EPA will submit a report 
containing this rule and other required information to the U.S. Senate, 
the U.S. House of Representatives, and the Comptroller General of the 
United States prior to publication of this final rule in the Federal 
Register. This final rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).
