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 on the basis of a petition 

under FFDCA section 408(d), such as 

the tolerance 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, not 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, 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). 

VII. 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

II. Summary of Petitioned-For 

Tolerance 

In the Federal Register of September 

23, 2022 (87 FR 58047) (FRL–9410–05– 

OCSPP), EPA issued a document 

pursuant to FFDCA section 408(d)(3), 21 

U.S.C. 346a(d)(3), announcing the filing 

of a pesticide petition (PP 2E9009) by 

BASF Corporation, 26 Davis Drive, 

Research Triangle Park, NC 27709–3528. 

The petition requested that 40 CFR 

180.500 be amended by establishing 

tolerances for residues of the herbicide 

imazapyr, (2-[4,5-dihydro- 4-methyl-4- 

(1-methylethyl)-5-oxo-1H-imidazol-2- 

yl]-3-pyridinecarboxylic acid), in or on 

rice, bran at 0.2 parts per million (ppm) 

and rice, grain at 0.06 ppm. That 

document referenced a summary of the 

petition prepared by BASF Corporation, 

the registrant, which is available in the 

docket, https://www.regulations.gov. 

There were no comments received in 

response to the notice of filing. 

Based upon review of the data 

supporting the petition, EPA is 

establishing one tolerance at a different 

level than requested by the registrant. 

The reason for these changes are 

explained in Unit IV.C. 

III. 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 FFDCA section 

408(b)(2)(D), and 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 for imazapyr 

including exposure resulting from the 

tolerances established by this action. 

EPA’s assessment of exposures and risks 

associated with imazapyr follows. 

A. Toxicological Profile 

EPA has evaluated the available 

toxicity data and considered its validity, 

completeness, and reliability as well as 

the relationship of the results of the 

studies to human risk. EPA has also 

considered available information 

concerning the variability of the 

sensitivities of major identifiable 

subgroups of consumers, including 

infants and children. 

No hazard was identified for imazapyr 

in the toxicity database, i.e., no toxicity 

was demonstrated in acceptable 

guideline studies generally up to the 

highest doses tested of 250–1,000 mg/ 

kg/day. The data also show that there is 

no evidence of neurotoxicity, 

immunotoxicity, genotoxicity, or 

carcinogenicity. Further, no adverse 

developmental effects or adverse 

reproductive effects were detected in 

well-conducted guideline studies. 

Therefore, EPA concluded that dietary, 

occupational, and residential exposures 

to imazapyr do not pose a significant 

human health risk. Although there is 

potential for exposure to imazapyr, no 

hazard was identified from the wellconducted toxicity studies. No adverse 

effects were observed in the submitted 

toxicological studies regardless of the 

route of exposure or the species tested. 

Therefore, risk assessments are not 

required. Furthermore, the toxicology 

database is considered to be adequate, 

and no additional studies are required. 

Specific information on the studies 

received and the nature of the adverse 

effects caused by imazapyr as well as 

the no-observed-adverse-effect-level 

(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the 

toxicity studies can be found at https:// 

www.regulations.gov in document titled 

‘‘Imazapyr Human Health Risks 

Assessment for the Establishment of 

Permanent Tolerances for Residues in/ 

on Rice’’ (hereinafter ‘‘Imazapyr Human 

Health Risk Assessment’’) on pages 12– 

15 in docket ID number EPA–HQ–OPP– 

2022–0577. 

B. Toxicological Points of Departure/ 

Levels of Concern 

Once a pesticide’s toxicological 

profile is determined, EPA identifies 

toxicological points of departure (POD) 

and levels of concern to use in 

evaluating the risk posed by human 

exposure to the pesticide. For hazards 

that have a threshold below which there 

is no appreciable risk, the toxicological 

POD is used as the basis for derivation 

of reference values for risk assessment. 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 88, No. 163 / Thursday, August 24, 2023 / Rules and Regulations 57893 

PODs are developed based on a careful 

analysis of the doses in each 

toxicological study to determine the the 

NOAEL and the the LOAEL. 

Uncertainty/safety factors are used in 

conjunction with the POD to calculate a 

safe exposure level—generally referred 

to as a population-adjusted dose (PAD) 

or a reference dose (RfD)—and a safe 

margin of exposure (MOE). For nonthreshold risks, the Agency assumes 

that any amount of exposure will lead 

to some degree of risk. Thus, the Agency 

estimates risk in terms of the probability 

of an occurrence of the adverse effect 

expected in a lifetime. For more 

information on the general principles 

EPA uses in risk characterization and a 

complete description of the risk 

assessment process, see https://

www.epa.gov/pesticide-science-andassessing-pesticide-risks/assessinghuman-health-risk-pesticides. 

Since no effects were seen in any 

guideline toxicity studies at doses 

relevant for human health risk 

assessment, no toxicological points of 

departure (PODs) were selected for 

imazapyr. 

C. Exposure Assessment 

1. Dietary exposure from food and 

feed uses. In evaluating dietary 

exposure to imazapyr, EPA considered 

exposure under the petitioned-for 

tolerances as well as all existing 

imazapyr tolerances in 40 CFR 180.500. 

There is likely to be dietary exposure to 

imazapyr from its registered uses as a 

pesticide on domestic crops. Should 

exposure occur, however, minimal to no 

risk is expected for the general U.S 

population, including infants and 

children, due to the low toxicity of 

imazapyr. 

2. Dietary exposure from drinking 

water. While there is no additional 

exposure expected from imazapyr 

tolerances for rice because it is for 

import only, there is likely to be dietary 

exposure to imazapyr in drinking water 

from its registered uses as a pesticide on 

domestic crops. Should exposure occur, 

however, minimal to no risk is expected 

for the general U.S population, 

including infants and children, due to 

the low toxicity of imazapyr. 

3. From non-dietary exposure. The 

term ‘‘residential exposure’’ is used in 

this document to refer to nonoccupational, non-dietary exposure 

(e.g., for lawn and garden pest control, 

indoor pest control, termiticides, and 

flea and tick control on pets). 

Imazapyr is currently registered in the 

United States for application in/around 

the home (homeowner application 

permitted) and to noncropland areas, 

aquatic sites, grasslands, and 

imidazolinone-tolerant field corn. Due 

to the low toxicity of imazapyr, 

quantitative exposure assessments are 

not required. Residential exposure to 

imazapyr is not expected to increase 

with this tolerance because these 

tolerances are for import only. EPA 

concludes with reasonable certainty that 

non-occupational exposures to imazapyr 

do not pose a significant human health 

risk. 

4. Cumulative effects from substances 

with a common mechanism of toxicity. 

Section 408(b)(2)(D)(v) of FFDCA 

requires that, when considering whether 

to establish, modify, or revoke a 

tolerance, the Agency consider 

‘‘available information’’ concerning the 

cumulative effects of a particular 

pesticide’s residues and ‘‘other 

substances that have a common 

mechanism of toxicity.’’ Unlike other 

pesticides for which EPA has followed 

a cumulative risk approach based on a 

common mechanism of toxicity, EPA 

has not made a common mechanism of 

toxicity finding as to imazapyr and any 

other substances. For the purposes of 

this action, therefore, EPA has not 

assumed that imazapyr has a common 

mechanism of toxicity with other 

substances. Further information 

regarding EPA Pesticide Commulative 

Risk Assessment can be found at https:// 

www.epa.gov/pesticide-science-andassessing-pesticide-risks/pesticidecumulative-risk-assessment-framework. 

D. Safety Factor for Infants and 

Children 

1. In general. Section 408(b)(2)(C) of 

FFDCA provides that EPA shall apply 

an additional tenfold (10X) margin of 

safety for infants and children in the 

case of threshold effects to account for 

prenatal and postnatal toxicity and the 

completeness of the database on toxicity 

and exposure unless EPA determines 

based on reliable data that a different 

margin of safety will be safe for infants 

and children. This additional margin of 

safety is commonly referred to as the 

Food Quality Protection Agency Safety 

Factor (SF). In applying this provision, 

EPA either retains the default value of 

10X, or uses a different additional safety 

factor when reliable data available to 

EPA support the choice of a different 

factor. 

2. Conclusion. No hazard was 

identified from the toxicity studies. No 

adverse effects were observed in the 

submitted toxicological studies 

regardless of the route of exposure or 

the species tested. The toxicology 

database for imazapyr is considered to 

be adequate. No additional toxicological 

studies are required, and no additional 

safety factors to protect children are 

needed and EPA is not retaining the 10X 

safety factor. 

E. Determination of Safety 

Taking into account the available data 

for imazapyr, EPA has concluded that 

given the lack of toxicity of this 

substance, no risks of concern are 

expected. Therefore, EPA concludes that 

there is a reasonable certainty that no 

harm will result to the general 

population, or to infants and children, 

from aggregate exposure to imazapyr. 

IV. Other Considerations 

A. Analytical Enforcement Methodology 

Adequate enforcement methodology 

(high-performance liquid 

chromatography with tandem mass 

spectroscopy (LC/MS/MS), method 

SOP–PA.0288) is available for tolerance 

enforcement. 

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: residuemethods@

epa.gov. 

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 has not established a MRL 

for imazapyr in or on rice. 

C. Revisions to Petitioned-For 

Tolerances 

EPA is establishing the tolerance for 

rice, bran at 0.15 ppm rather than at 0.2 

ppm as requested by the petitioner. The 

rice, bran tolerance is based on the 

highest average field trial residue (0.031 

ppm) and the median rice bran 

processing factor of 3.2x. (0.031 ppm × 

3.2 = 0.099 ppm). The tolerance is being 

established at 0.15 ppm because that is 

the rounding class after 0.1 ppm. For the 

rice grain tolerance of 0.06 ppm, EPA 

used the Organization for Economic Cooperation and Development (OECD) 

maximum residue limit (MRL) 

calculation procedures. 

V. Conclusion 

Therefore, tolerances are established 

for residues of imazapyr (2-[4,5-dihydro4-methyl-4-(1-methylethyl)-5-oxo-1Himidazol-2-yl]-3-pyridinecarboxylic 

acid), in or on rice, bran at 0.15 ppm 

and rice, grain at 0.06 ppm.

VI. Statutory and Executive Order 

Reviews 

This action establishes tolerances 

under FFDCA section 408(d) in 

response to a petition submitted to the 

Agency. 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 on the basis of a petition 

under FFDCA section 408(d), 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, not 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, 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). 

VII. 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).
