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).

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

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

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

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

[[Page 15194]]
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

[[Page 15195]]
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:

    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

[[Page 15196]]
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).
