Pesticide Tolerances for Glyphosate
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------

SUMMARY: This document establishes tolerances and feed additive
regulations for residues of the herbicide glyphosate [(N-phosphonometyhyl)
glycine]. The specific proposals are as follows:
establishment of tolerances for alfalfa hay at 200 parts per million
(ppm), alfalfa forage at 75 ppm, soybean aspirated grain fractions at
50 ppm; sunflower seed at 0.1 ppm, increased tolerances on the kidney
of cattle, goats, hog, horses, and sheep from 0.5 to 4.0 ppm; an
amended tolerance removing the metabolite aminomethylphosphonic acid
(AMPA) from the expression and increasing the established tolerance for
soybean forage from 15 to 100 ppm; amended tolerances removing the
metabolite AMPA from the expressions for the established tolerances
soybean, grain at 20 ppm, and soybean, hay at 200 ppm; deletion of the
established tolerances for soybean straw at 200 ppm; and an amended
feed additive regulation removing the metabolite AMPA from the
expression for the established tolerance soybean hulls at 100 ppm. This
rule also amends the current tolerance for citrus fruits and the feed
additive regulation for citrus pulp, dried by removing the metabolite
AMPA from the expressions and increasing the tolerance for citrus
fruits from 0.2 to 0.5 ppm and increasing the tolerance for citrus
pulp, dried from 1.0 to 1.5 ppm. Monsanto Company requested these
tolerances and feed additive regulation in petitions submitted to EPA
pursuant to the Federal Food, Drug, and Cosmetic Act (FFDCA).

EFFECTIVE DATES: These regulations become effective April 5, 1996.

SUPPLEMENTARY INFORMATION: EPA issued notices in the Federal Register,
announcing that the Monsanto Co., 700 14th St., NW., Suite #1100,
Washington, DC 20005, had submitted petitions proposing to amend 40 CFR
part 180 pursuant to section 408 (d) of the Federal Food, Drug, and
Cosmetic (FFDCA) (21 U.S.C. 346(a), and 40 CFR part 186 under sec 409
of FFDCA (21 U.S.C. 348) by establishing regulations to permit the
combined residues of the herbicide glyphosate [N-(phosphonomethyl)glycine]
and its metabolite aminomethylphosphonic acid (AMPA) or glyphosate in or on
certain raw agricultural commodities (RACs).
    1. PP 6F3408. Published in the Federal Register of September 13,
1995 (60 FR 47578), the notice proposed establishing a regulation to
permit combined residues of glyphosate and its metabolite AMPA in or on
sunflowers at 0.1 ppm.
    2. PP 4F4312. Published in the Federal Register of July 13, 1994
(59 FR 35718), the notice proposed to amend 40 CFR 180.364 by
establishing a regulation to permit residues of glyphosate and its
metabolite AMPA resulting from the application of the isopropylamine
salt of glyphosate and/or the monoammonium salt of glyphosate in or on
alfalfa, hay at 200 ppm and alfalfa forage at 75 ppm.
    3. PP 4F4338. Published in the Federal Register of November 2, 1994
(59 FR 54907), the notice proposed to amend 40 CFR 180.364 by
establishing a regulation permitting residues of glyphosate and its
metabolite AMPA resulting from the application of the isopropylamine
salt of glyphosate and/or the monoammonium salt of glyphosate in or on
citrus fruits at 0.5 ppm.
    4. PP 4F4369. Published in the Federal Register of February 8, 1995
(60 FR 7540), the notice proposed to amend 40 CFR 180.364 by
establishing a regulation to permit residues of glyphosate resulting
from the application of the isopropyl amine salt of glyphosate and/or
the monoammonium salt of glyphosate in or on soybean forage at 100 ppm.
    5. PP 4H5692. Published in the Federal Register of July 13, 1994
(59 FR 35720), the notice proposed establishing a feed additive
regulation to permit the combined residues of glyphosate and its
metabolite aminomethylphosphonic acid (AMPA) in alfalfa meal at 400
ppm.
    6. PP 4H4701. Published in the Federal Register of March 16, 1995
(60 FR 13979), the notice proposed to amend 40 CFR 186.3500 by
establishing a feed additive regulation to permit residues of
glyphosate resulting from the application of the isopropylamine salt
and/or monoammonium salt of glyphosate on the feed commodity soybeans,
aspirated grain fractions at 30 parts per million.
    7. PP 4H5705. Published in the Federal Register of November 2, 1994
(59 FR 54907), the notice proposed to amend 40 CFR 185.3500 by
establishing a feed additive regulation to permit residues of
glyphosate and its metabolite aminomethylphosphonic acid in or on
citrus pulp, dried at 1.0 ppm.
    There were no comments or requests for referral to an advisory
committee received in response to these notices of filing.
    Subsequently, the petitioner amended several of the petitions by
submitting revised Section F's. Amended filing notices were published
in the Federal Register of September 13, 1995 (60 FR 47578, 79)
proposing these changes.
    1. PP 4F4312. Monsanto amended this petition by proposing that 40
CFR 180.364 be amended by removing the metabolite AMPA from the
expression and by establishing a regulation to permit residues of
glyphosate resulting from the application of the isopropylamine salt of
glyphosate and/or the monoammonium salt of glyphosate and/or
monoammonium salt of glyphosate for herbicidal and plant growth
regulator purposes and/or sodium sesqui salt of glyphosate for growth
regulator purposes in or on the kidney of cattle, goats, hogs, sheep,
and horses at 4.0 ppm.
    2. PP 4F4338. Monsanto amended this petition by proposing to remove
the metabolite AMPA from the expression.
    3. PP 4F4369. Monsanto amended this petition by proposing that 40
CFR 180.364 be amended by establishing a regulation to permit residues
of the herbicide glyphosate resulting from the application of the
isopropylamine salt of glyphosate in or on the raw agricultural
commodities (RACs) soybean grain at 20 ppm, soybean forage at 100 ppm,
soybean hay at 200 ppm, and soybean aspirated grain fractions at 50
ppm. These tolerances are to replace the existing tolerances for
soybeans, soybean forage, soybean hay, and soybean straw.
    4. PP 4H5701. Monsanto amended this petition by deleting the feed
commodity soybean, aspirated grain fractions at 30 ppm from this
expression and reproposing it as a raw agricultural commodity under PP
4F4369. Monsanto also proposed that a feed additive regulation be
established permitting residues of glyphosate resulting from the
application of the isopropylamine salt of glyphosate and/or the
monoammonium salt of glyphosate in or the feed commodity soybean hulls
at 100 ppm. This entry would replace the current entry for soybean
hulls.
    5. PP 4H5705. Monsanto amended this petition by proposing that 40
CFR part 186 be amended by establishing a regulation to permit residues
of glyphosate in or on the feed commodity citrus pulp, dried at 1.5
ppm.
    The Agency received one comment opposing the tolerances stated in
the amended filing notices published September 13, 1995. The
commenter's opposition to the tolerances was based upon toxicological
concerns including the concept of "NOEL" (no observed effect level);
the use of animal testing to represent human reaction to potentially
toxic substances (pesticides); the indications of a link between
pesticide exposure and Parkinson's Disease (PD).
    The Agency has reviewed the comment and decided to proceed with
these tolerances. The Agency, made the decision that a wide variety of
toxicological studies would serve as the basis for determining if a
pesticide could be requested and used without reasonable risk. It is
true that animal models do not and can not predict every possible human
reaction to pesticides, but the general consensus is that they offer the best
information as to what a pesticide might do to humans. Usually, the Agency
requires and reviews long-term studies in rodents and non-rodents to determine
a dose which causes no apparent adverse effects (NOEL). The NOEL is divided by
an uncertainty factor-often at least 100- to arrive at doses or exposures that
should not cause harmful effects on humans. In our regulation of pesticides,
the Agency does not approve uses which will cause unreasonable adverse effects
to humans or the environment.
    The Agency understands that the testing of one pesticide does not
predict all the possible adverse interactions with other pesticides--or
for that matter other drugs or environmental pollutants. The Agency is
exploring ways of testing for the interactions of pesticides having
similar toxicity endpoint, but progress in that area is low.
    With reference to the indications of a link between pesticide
exposure and Parkinson's Disease, the Agency is aware that many
researchers are investigating the potential reaction of pesticide
exposures to chronic neurological diseases including Parkinson's
Disease, and additional research is needed to study this important
area. Available studies in humans or animals have not yet established
any relationship between pesticide exposures and Parkinson's Disease.
    During the course of the review the Agency determined that the
proposed tolerance for alfalfa meal (59 FR 35720) was not necessary
since the proposed tolerance on alfalfa hay will cover any residue in
meal. This petition (4H5692) was withdrawn.
    The filing notice for PP 6F3408 was amended by submitting a revised
section F deleting the metabolite AMPA from the expression, Because
this is a deletion of a metabolite not longer regulated by the Agency,
there is no potential risk to humans, therefore no additional period of
public comment is necessary.
    The amended notice of filing for 4F4369 should have included the
monoammonium salt of glyphosate in the expression. The amended notice
of filing for 4H5701 should have not included reference to the salts of
glyphosate. Because these corrections are a correction of wording in
the expression, there is no potential increased risk to humans,
therefore no additional period of public comment is necessary.
    The data submitted in the petitions and other relevant material
have been evaluated. The glyphosate toxicological data listed below
were considered in support of these tolerances.
    1. Several acute toxicology studies placing technical-grade
glyphosate in Toxicity Category III and Toxicity Category IV.
    2. A 1-year feeding study with dogs fed dosage levels of 0, 20,
100, and 500 milligrams/kilogram/day (mg/kg/day) with a no-observable-
effect level (NOEL) of 500 mg/kg/day.
    3. A 2-year carcinogenicity study in mice fed dosage levels of 0,
150, 750, and 4,500 mg/kg/day with no carcinogenic effect at the
highest dose tested (HDT) of 4,500 mg/kg/day.
    4. A chronic feeding/carcinogenicity study in male and female rats
fed dosage levels of 0, 3, 10, and 31 mg/kg/day (males) and 0, 3, 11,
or 34 mg/kg/day (females) with no carcinogenic effects observed under
the conditions of the study at dose levels up to and including 31 mg/
kg/day (HDT) (males) and 34 mg/kg/day (HDT) (females) and a systemic
NOEL of 31 mg/kg/day (HDT)(males) and 34 mg/kg/day (HDT) (females).
Because a maximum tolerated dose (MTD) was not reached, this study was
classified as supplemental for carcinogenicity.
    5. A chronic feeding/carcinogenicity study in male and female rats
fed dosage levels of 0, 89, 362, and 940 mg/kg/day (males) and 0, 113,
457, and 1183 mg/kg/day (females) with no carcinogenic effects noted
under the conditions of the study at dose levels up to and including
940/1183 mg/kg/day (males/females) (HDT) and a systemic NOEL of 362 mg/
kg/day (males) based on an increased incidence of cataracts and lens
abnormalities, decreased urinary pH, increased liver weight and
increased liver weight/brain ratio (relative liver weight) at 940 mg/
kg/day (males) (HDT) and 457 mg/kg/day (females) based on decreased
body weight gain 1183 mg/kg/day (females) (HDT).
    6. A developmental toxicity study in rats given doses of 0, 300,
1,000, and 3,500 mg/kg/day with a developmental NOEL of 1,000 mg/kg/day
based on an increase in number of litters and fetuses with unossified
sternebrae, and decrease in fetal body weight at 3,500 mg/kg/day, and a
maternal NOEL of 1,000 mg/kg/day based on decrease in body weight gain,
diarrhea, soft stools, breathing rattles, inactivity, red matter in the
region of nose, mouth, forelimbs, or dorsal head, and deaths at 3,500
mg/kg/day (HDT).
    7. A developmental toxicity study in rabbits given doses of 0, 75,
175, and 350 mg/kg/day with a developmental NOEL of 350 mg/kg/day
(HDT); a maternal NOEL of 175 mg/kg/day based on increased incidence of
soft stool, diarrhea, nasal discharge, and deaths at 350 mg/kg/day
(HDT).
    8. A multigeneration reproduction study with rats fed dosage levels
of 0, 3, 10, and 30 mg/kg/day with a developmental NOEL of 10 mg/kg/day
based on increased incidence of focal tubular dilation of the kidney
(both unilateral and bilateral combined) of male F3b pups.
    9. A two generation reproduction study with rats fed dosage levels
of 0, 100, 500, and 1,500 mg/kg/day with a developmental NOEL of 500
mg/kg/day based on decreased pup body weight and body weight gain on
lactation days 14 and 21 at 1,500 mg/kg/day (HDT), a systemic NOEL of
500 mg/kg/day based on soft stools in Fo and F1 males and females at
1500 mg/kg/day (HDT) and a reproductive NOEL of 1500 mg/kg/day (HDT).
    10. Mutagenicity data included chromosomal aberration in vitro (no
aberrations in Chinese hamster ovary cells were caused with and without
S9 activation); DNA repair in rat hepatocyte; in vivo bone marrow
cytogenic test in rats; rec-assay with B. subtilis; reverse mutation
test with S. typhimurium; Ames test with S. typhimurium; and dominant-
lethal mutagenicity test in mice (all negative).
    The reference dose (RfD) based on a developmental study with
rabbits (NOEL of 175 mg/kg/ bwt/day) and using a hundred-fold safety
factor is calculated to be 2.0 mg/kg body weight/day. The theoretical
maximum residue contribution (TMRC) for published tolerances and food
and feed additive regulations is 0.020733 mg/kg bwt/day or 1.0 percent
of the RfD for the overall U.S. population. The current actions on
citrus fruits, citrus dried pulp, alfalfa, kidney of cattle, goats,
hog, horses, and sheep, sunflower, and soybean forage will contribute
0.000726 mg/kg/bwt/day to the TMRC. These tolerances and the food
additive regulation will utilize a total of 1.0 percent of the RfD for
the overall U.S. population.
    For both U.S. subgroup populations, nonnursing infants and children
1 to 6 years of age, the current action and previously established
tolerances and the food additive regulation utilize, a total of 2.5
percent of the RfD, assuming that residue levels are at the established
tolerance levels and that 100 percent of the crop is treated.
    There are no desirable data lacking for this pesticide. There are
currently no actions pending against the continued registration of this
pesticide. No detectable residues of N-nitrosoglyphosate, a contaminant
of glyphosate, are expected to be present in the commodities for which
tolerances are established. The carcinogenic potential of glyphosate was first
considered by a panel, then called the Toxicology Branch AD Hoc
Committee, in 1985. The Committee, in a consensus review dated March 4,
1985, classified glyphosate as a Group C carcinogen based on an
increased incidence of renal tumors in male mice. The Committee also
concluded that dose levels tested in the 26-month rat study were not
adequate for assessment of glyphosate's carcinogenic potential in this
species. These findings, along with additional information, including a
reexamination of the kidney slides from the long-term mouse study, were
referred to the FIFRA Scientific Advisory Panel (SAP). In its report
dated February 24, 1986, SAP classified glyphosate as a Group D
Carcinogen (inadequate animal evidence of carcinogenic potential). SAP
concluded that, after adjusting for the greater survival in the high-
dose mice compared to concurrent controls, that no statistically
significant pairwise differences existed, although the trend was
significant.
    The SAP determined that the carcinogenic potential of glyphosate
could not be determined from existing data and proposed that the rat
and/or mouse studies be repeated in order to classify these equivocal
findings. On reexamination of all information, the Agency classified
glyphosate as a Group D Carcinogen and requested that the rat study be
repeated and that a decision on the need for a repeat mouse study would
be made upon completion of review of the rat study.
    Upon receipt and review of the second rat chronic feeding/
carcinogenicity study, all toxicological findings for glyphosate were
referred to the Health Effects Division Carcinogenicity Peer Review
Committee on June 26, 1991, for discussion and evaluation of the weight
of evidence on glyphosate with particular emphasis on its carcinogenic
potential. The Peer Review Committee classified glyphosate as a Group E
(evidence of noncarcinogenicity for humans), based upon lack of
convincing carcinogenicity evidence in adequate studies in two animal
species. This classification is based on the following findings: (1)
None of the types of tumors observed in the studies (pancreatic islet
cell adenomas in male rat, thyroid c-cell adenomas and/or carcinomas in
male and female rats, hepatocellular adenomas and carcinomas in male
rats, and renal tubular neoplasms in male mice) were determined to be
compound related; (2) glyphosate was tested up to the limit dose on the
rat and up to levels higher than the limit dose in mice; and (3) there
is no evidence of genotoxicity for glyphosate. Accordingly, EPA
concludes that glyphosate has not been "found to induce cancer when
ingested by man or animal." 21 U.S.C. 348(c)(3).
    The nature of the residue in plants is adequately understood,
adequate methodology (HPLC) with flurometric detection is available for
enforcement purposes, and the methodology has been published in the
Pesticide Analytical Manual (PAM), Vol. II. Any secondary residues
occurring in liver of cattle, goats, horses, hogs, and sheep and liver
and kidney of poultry will be covered by existing tolerances. Any
secondary residues occurring in kidney of cattle, goats, hogs, horses,
and sheep will be covered by the 4.0 ppm tolerances being established
concurrently.
    The pesticide is considered useful for the purpose for which the
regulation is sought and is capable of achieving the intended physical
or technical effect.
    Based on the information cited above, the Agency has determined
that the establishment of tolerances by amending 40 CFR part 180 will
protect the public health, and the establishment of feed additive
regulations by amending 40 CFR part 186 will be safe. Therefore, EPA is
establishing the tolerances and feed additive regulations as set forth
below.
    Any person adversely affected by this regulation may, within 30
days after publication of this document in the Federal Register, file
written objections with the Hearing Clerk, at the address given above.
40 CFR 178.20. A copy of the objections and/or hearing requests filed
with the Hearing Clerk should be submitted to the OPP docket for this
rulemaking. The objections submitted must specify the provisions of the
regulation deemed objectionable and the grounds for the objections. 40
CFR 178.25. Each objection must be accompanied by the fee prescribed by
40 CFR 180.33(i). If a hearing is requested, the objections must
include a statement of the factual issue(s) on which the hearing is
requested, the requestor's contentions on each such issue, and a
summary of any evidence relied upon by the objector. 40 CFR 178.27. A
request for a hearing will be granted if the Administrator determines
that the material submitted shows the following: There is a genuine and
substantial issue of fact; there is a reasonable possibly that
available evidence identified by the requestor would, if established,
resolve one or more issues in favor of the requestor, taking into
account uncontested claims or facts to the contrary; and resolution of
the factual issue(s) in the manner sought by the requestor would be
adequate to justify the action requested. 40 CFR 178.32.
    A record has been established for this rulemaking under docket
number [PP 6F3408, 4F4312, 4F4338, 4F4369, FAP 4H5701, 4H5705/R2204]
(including objections and hearing requests submitted electronically as
described below). A public version of this record, including printed,
paper versions of electronic comments, which does not include any
information claimed as CBI, is available for inspection from 8 a.m. to
4:30 p.m., Monday through Friday, excluding legal holidays. The public
record is located in Room 1132 of the Public Response and Program
Resources Branch, Field Operations Division (7506C), Office of
Pesticide Programs, Environmental Protection Agency, Crystal Mall #2,

    Written objections and hearing requests, identified by the document
control number [PP 6F3804, 4F4312, 4F4338, 4F4369, FAP 4h5701, 4H5705/
R2204] may be submitted to the Hearing Clerk (1900), Environmental
Protection Agency, Rm 3708, 401 M St SW., Washington, DC 20460. A copy
of electronic objections and hearing requests filed with the Hearing
Clerk can be sent directly to EPA at:
opp-Docket@epamail.epa.gov
    A copy of electronic objections and hearing requests filed with the
Hearing Clerk must be submitted as an ASCII file avoiding the use of
special characters and any form of encryption.
    The official record for this rulemaking, as well as the public
version, as described above will be kept in paper form. Accordingly,
EPA will transfer any objections and hearing requests received
electronically into printed, paper form as they are received and will
place the paper copies in the official rulemaking record which will
also include all objections and hearing requests submitted directly in
writing. The official rulemaking record is the paper record maintained
at the address in "ADDRESSES" at the beginning of this document.
    Under Executive Order 12866 (58 FR 51735, October 4, 1993), the
Agency must determine whether the regulatory action is "significant"
and therefore subject to review by the Office of Management and Budget
(OMB) and the requirements of the Executive Order. Under section 3(f),
the order defines a "significant regulatory action " as an action
that is likely to result in a rule (1) having an annual effect on the
economy of $100 million or more, or adversely and materially affecting
a sector of the economy, productivity, competition,jobs, the environment,
public health or safety, or State, local, or tribal governments or
communities (also referred to as "economically significant"); (2)
creating serious inconsistency or otherwise interfering with an action
taken or planned by another agency; (3) materially altering the
budgetary impacts of entitlement, grants, user fees, or loan programs
or the rights and obligation of recipients thereof; or (4) raising
novel legal or policy issues arising out of legal mandates, the
President's priorities, or the principles set forth in this Executive
Order.
    Pursuant to the terms of the Executive Order, EPA has determined
that this rule is not "significant" and is therefore not subject to
OMB review. Pursuant to the requirements of the Regulatory Flexibility
Act (Pub. L. 96-354, 94 Stat. 1164, 5 U.S.C. 601-612), the
Administrator has determined that regulations establishing new
tolerances or raising tolerance levels or establishing exemptions from
tolerance requirements do not have a significant impact on a
substantial number of small entities. A certification statement to this
effect was published in the Federal Register of May 4, 1981 (46 FR 24950).
