Fluridone; Pesticide Tolerances for Emergency Exemptions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This regulation establishes time-limited tolerances for 
residues of the herbicide fluridone including its degradates and 
metabolites in or on peanut and peanut, hay. This action is in response 
to EPA's granting of an emergency exemption under the Federal 
Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of 
the pesticide on peanut. This regulation establishes a maximum 
permissible level for residues of fluridone in or on these commodities. 
The time-limited tolerances expire on December 31, 2024.

DATES: This regulation is effective February 28, 2022. Objections and 
requests for hearings must be received on or before April 29, 2022, and 
must be filed in accordance with the instructions provided in 40 CFR 
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Background and Statutory Findings

    EPA, on its own initiative, in accordance with FFDCA sections 
408(e) and 408(l)(6) of, 21 U.S.C. 346a(e) and 346a(l)(6), is 
establishing time-limited tolerances for residues of fluridone, in or 
on peanut at 0.1 parts per million (ppm) and peanut, hay at 0.1 ppm. 
These time-limited tolerances expire on December 31, 2024.
    Section 408(l)(6) of FFDCA requires EPA to establish a time-limited 
tolerance or exemption from the requirement of a tolerance for 
pesticide chemical residues in food that will result from the use of a 
pesticide under an emergency exemption granted by EPA under FIFRA 
section 18. Such tolerances can be established without providing notice 
or period for public comment. EPA does not intend for its actions on 
FIFRA section 18-related time-limited tolerances to set binding 
precedents for the application of FFDCA section 408 and the safety 
standard to other tolerances and exemptions. Section 408(e) of FFDCA 
allows EPA to establish a tolerance or an exemption from the 
requirement of a tolerance on its own initiative, i.e., without having 
received any petition from an outside party.
    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings but does not include occupational exposure. 
Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue. . . 
.''
    Section 18 of FIFRA authorizes EPA to exempt any Federal or State 
agency from any provision of FIFRA, if EPA determines that ``emergency 
conditions exist which require such exemption.'' EPA has established 
regulations governing such emergency exemptions in 40 CFR part 166.

III. Emergency Exemption for Fluridone on Peanut and Peanut, Hay and 
FFDCA Tolerances

    The Arkansas and Missouri Departments of Agriculture submitted 
specific emergency exemptions for the use of fluridone on peanut to 
control Palmer amaranth, Amaranthus palmeri, populations in peanut 
fields where glyphosate-resistant Palmer amaranth biotypes are present. 
According to the States, peanut growers in Arkansas and Missouri are 
experiencing widespread multiple herbicide-resistant populations of 
Palmer amaranth. These States reported that an urgent and non-routine 
situation exists because a registered effective soil residual herbicide 
is currently unavailable to reduce the impact and prevent the expansion 
of this destructive weed species. Significant economic losses are 
expected for peanut growers due to yield and quality decreases without 
a suitable pesticide control.
    After having reviewed the submission, EPA determined that an 
emergency condition exists for these States, and that the criteria for 
approval of these emergency exemptions have been met.
    As part of its evaluation of these emergency exemption 
applications, EPA assessed the potential risks presented by residues of 
fluridone in or on peanut at 0.1 ppm and peanut, hay at 0.1 ppm. In 
doing so, EPA considered the safety standard in FFDCA section 
408(b)(2), and EPA decided that the necessary tolerances under FFDCA 
section 408(l)(6) would be consistent with the safety standard and with 
FIFRA section 18. Consistent with the need to move quickly on these 
emergency exemptions in order to address an urgent non-routine 
situation in these States and to ensure that the resulting food is safe 
and lawful, EPA is issuing these tolerances without notice and 
opportunity for public comment as provided in FFDCA section 408(l)(6). 
Although these time-limited tolerances expire on December 31, 2024, 
under FFDCA section 408(l)(5), residues of the pesticide not in excess 
of the amounts specified in the tolerance remaining in or on peanut 
after that date will not be unlawful, provided the pesticide was 
applied in a manner that was lawful under FIFRA, and the residues do 
not exceed a level that was authorized by these time-limited tolerances 
at the time of that application. EPA will take action to revoke these 
time-limited tolerances earlier if any experience with, scientific data 
on, or other relevant information on this pesticide indicate that the 
residues are not safe.
    Because these time-limited tolerances are being approved under 
emergency conditions, EPA has not made any decisions about whether 
fluridone meets FIFRA's registration requirements for use on peanut or 
whether permanent tolerances for this use would be

[[Page 10981]]

appropriate. Under these circumstances, EPA does not believe that these 
time-limited tolerance decisions serve as a basis for registration of 
fluridone by a State for special local needs under FIFRA section 24(c). 
Nor do these tolerances by themselves serve as the authority for 
persons in States other than Arkansas and Missouri to use this 
pesticide on the applicable crops under FIFRA section 18 absent the 
issuance of an emergency exemption applicable within that State. For 
additional information regarding the emergency exemptions for 
fluridone, contact the Agency's Registration Division at the address 
provided under FOR FURTHER INFORMATION CONTACT.

IV. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings but does not include occupational exposure. 
Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue. . . 
.''
    Consistent with the factors specified in FFDCA section 
408(b)(2)(D), EPA has reviewed the available scientific data and other 
relevant information in support of this action. EPA has sufficient data 
to assess the hazards of and to make a determination on aggregate 
exposure expected as a result of these emergency exemption requests and 
the time-limited tolerances for residues of fluridone on peanut at 0.1 
ppm and peanut, hay at 0.1 ppm. EPA's assessment of exposures and risks 
associated with establishing these time-limited tolerances follows.
    In an effort to streamline its publications in the Federal 
Register, EPA is not reprinting sections that repeat what has been 
previously published for tolerance rulemakings of the same pesticide 
chemical. Where scientific information concerning a particular chemical 
remains unchanged, the content of those sections would not vary between 
tolerance rulemakings, and EPA considers referral back to those 
sections as sufficient to provide an explanation of the information EPA 
considers in making its safety determination for the new rulemaking.
    In the Federal Register of May 18, 2020 (85 FR 29633) (FRL-10007-
09), EPA published a final rule that established tolerances for 
residues of fluridone in or on multiple commodities based on the 
Agency's determination that aggregate exposure to fluridone resulting 
from the residues subject to those tolerances is safe for the U.S. 
general population, including infants and children. EPA is 
incorporating sections from that final rule as described further in 
this rulemaking, as they remain unchanged.
    Toxicological profile. The toxicological profile for fluridone has 
not changed since the May 18, 2020, final rule was published; 
therefore, EPA is relying upon the discussion of that profile in Unit 
III. A. as part of this rulemaking.
    Toxicological points of departure/Levels of concern. The 
toxicological points of departure and levels of concern for fluridone 
have not changed since the May 18, 2020, final rule was published; 
therefore, EPA is relying upon the discussion in Unit III. B. as part 
of this rulemaking.
    Exposure assessment. Much of the exposure assessment for fluridone 
remains unchanged from the discussion in Unit III. C. of the May 18, 
2020, final rule, except that EPA considered the additional dietary 
exposure from the time-limited tolerances established by this action. 
Specifically, EPA conducted acute and chronic dietary exposure 
assessments to determine if the emergency use on peanut increases the 
dietary exposure to fluridone. Updated acute and chronic Dietary 
Exposure Evaluation Model (DEEM) runs were conducted with peanut 
included at a 0.1 ppm residue level. These results compared to the most 
recent dietary assessment supporting the May 18, 2020, final rule 
showed no exposure changes to two significant figures. Therefore, the 
previous assessment is protective of dietary exposure potential from 
the emergency use of fluridone on peanut.
    Safety factor for infants and children. EPA continues to conclude 
that there is reliable data showing that the safety of infants and 
children would be adequately protected if the Food Quality Protection 
Act (FQPA) safety factor were reduced from 10X to 1X. The reasons for 
that determination are articulated in Unit III. D. of the May 18, 2020, 
final rule.
    Aggregate risks and determination of safety. EPA determines whether 
acute and chronic dietary pesticide exposures are safe by comparing 
aggregate exposure estimates to the acute population-adjusted dose 
(aPAD) and chronic population-adjusted dose (cPAD). Short-, 
intermediate-, and chronic-term risks are evaluated by comparing the 
estimated aggregate food, water, and residential exposure to the 
appropriate points of departure (PODs) to ensure that an adequate 
margin of exposure (MOE) exists.
    The results of the acute and chronic analyses for fluridone do not 
exceed the Agency's level of concern (LOC). That is, all risk estimates 
were <100% of the aPAD or <100 of the cPAD and are not of concern for 
the general U.S. population and all population subgroups. The acute 
dietary exposure from food and water will occupy 2.3% of the aPAD for 
all infants (1-year old), the population with the highest estimated 
risk. Chronic exposure to fluridone from food and water will utilize 7% 
of the cPAD for children aged 1 to 2, the population with the highest 
estimated risk.
    The short-term aggregate exposure assessment for fluridone is based 
on food and drinking water as well as residential uses. For short-term 
aggregate risk assessment, potential residential exposures (dermal, 
inhalation, and incidental ingestion from swimming in treated waters 
for children; dermal and inhalation from applications via pouring into 
recreational ponds for adults) were combined with background dietary 
exposures. The combined short-term food, water, and residential 
exposures result in aggregate MOEs for of 1,300 for adults and 1,600 
for children, which are greater than the LOC of 100. Because EPA's 
level of concern for fluridone is an MOE of 100 or below, these MOEs 
are not of concern. Fluridone is not registered for any use patterns 
that would result in intermediate-term residential exposure.
    Further, since there is no evidence of carcinogenicity in the 
toxicological database for fluridone, EPA concluded that fluridone is 
not carcinogenic and is classified as ``not likely'' to be a human 
carcinogen.
    Therefore, based on the risk assessments and information described 
above, EPA concludes that there is reasonable certainty that no harm 
will result to the U.S. general population, or to infants and children 
from aggregate exposure to fluridone residues. More detailed 
information on the subject

action to establish time-limited tolerances in or on peanut and peanut, 
hay can be found at https://www.regulations.gov in the document 
entitled, ``Fluridone: ID# 21AR03 Section 18 Specific Exemption for Use 
on Peanut in Arkansas.'' This document can be found in docket ID number 
EPA-HQ-OPP-2021-0337.

V. Other Considerations

A. Analytical Enforcement Methodology

    An adequate enforcement methodology (high performance liquid 
chromatography (HPLC) method (originally submitted as method AM-AA-CA-
RO52-AA-755)) is available to enforce the tolerance expression.
    The method may be requested from: Chief, Analytical Chemistry 
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 
20755-5350; telephone number: (410) 305-2905; email address: 
[email protected].

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. EPA 
considers the international maximum residue limits (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex is a joint United Nations Food and 
Agriculture Organization/World Health Organization food standards 
program, and it is recognized as an international food safety 
standards-setting organization in trade agreements to which the United 
States is a party. EPA may establish a tolerance that is different from 
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain 
the reasons for departing from the Codex level.
    The Codex has not established a MRL for fluridone.

VI. Conclusion

    Therefore, time-limited tolerances are established for residues of 
fluridone, in or on peanut at 0.1 ppm and peanut, hay at 0.1 ppm. These 
tolerances expire on December 31, 2024.

VII. Statutory and Executive Order Reviews

    This action establishes tolerances under FFDCA sections 408(e) and 
408(l)(6). The Office of Management and Budget (OMB) has exempted these 
types of actions from review under Executive Order 12866, entitled 
``Regulatory Planning and Review'' (58 FR 51735, October 4, 1993). 
Because this action has been exempted from review under Executive Order 
12866, this action is not subject to Executive Order 13211, entitled 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001) or Executive 
Order 13045, entitled ``Protection of Children from Environmental 
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997). This 
action does not contain any information collections subject to OMB 
approval under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et 
seq., nor does it require any special considerations under Executive 
Order 12898, entitled ``Federal Actions to Address Environmental 
Justice in Minority Populations and Low-Income Populations'' (59 FR 
7629, February 16, 1994).
    Since tolerances and exemptions that are established in accordance 
with FFDCA sections 408(e) and 408(l)(6), such as the tolerances in 
this final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.) do not apply.
    This action directly regulates growers, food processors, food 
handlers, and food retailers, but does not regulate States or Tribes, 
nor does this action alter the relationships or distribution of power 
and responsibilities established by Congress in the preemption 
provisions of FFDCA section 408(n)(4). As such, the Agency has 
determined that this action will not have a substantial direct effect 
on States or Tribal Governments, or on the relationship between the 
National Government and the States or Tribal Governments, or on the 
distribution of power and responsibilities among the various levels of 
government or between the Federal Government and Indian Tribes. Thus, 
the Agency has determined that Executive Order 13132, entitled 
``Federalism'' (64 FR 43255, August 10, 1999) and Executive Order 
13175, entitled ``Consultation and Coordination with Indian Tribal 
Governments'' (65 FR 67249, November 9, 2000) do not apply to this 
action. In addition, this action does not impose any enforceable duty 
or contain any unfunded mandate as described under Title II of the 
Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.).
    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 (NTTAA) (15 U.S.C. 272 note).

VIII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
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 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
