II. Summary of Petitioned-For 

Tolerance 

In the Federal Register of July 5, 2023 

(88 FR 42935) (FRL–10579–05–OCSPP), 

EPA issued a document pursuant to 

FFDCA section 408(d)(3), 21 U.S.C. 

346a(d)(3), announcing the filing of 

pesticide petition (PP2E9028) by the 

Interregional Research Project No. 4 (IR– 

4), North Carolina State University, 

1730 Varsity Drive, Venture IV, Suite 

210, Raleigh, NC 27606. The petition 

requests to amend 40 CFR 180.417 by 

establishing a tolerance for residues of 

triclopyr, 2-[(3,5,6-trichloro-2- 

pyridinyl)oxy]acetic acid, including its 

metabolites and degradates, in or on 

sugarcane, cane at 0.04 parts per million 

(ppm) resulting from the application of 

the butoxyethyl ester of triclopyr, 

triethylamine salt of triclopyr, or 

choline salt of triclopyr. The petition 

also requests to remove the established 

time-limited tolerance for residues of 

triclopyr in or on sugarcane, cane at 40 

ppm. That document referenced a 

summary of the petition prepared by IR– 

4, the petitioner, which is available in 

the docket (EPA–HQ–OPP–2022–0890), 

https://www.regulations.gov. 

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 


ddrumheller on DSK120RN23PROD with RULES1
14592 Federal Register / Vol. 89, No. 40 / Wednesday, February 28, 2024 / Rules and Regulations 

therein, 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 triclopyr 

including exposure resulting from the 

tolerances established by this action. 

EPA’s assessment of exposures and risks 

associated with triclopyr 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 for 

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 

considered in making its safety 

determination for the new rulemaking. 

EPA has previously published 

tolerance rulemakings for triclopyr in 

which EPA concluded, based on the 

available information, that there is a 

reasonable certainty that no harm would 

result from aggregate exposure to 

triclopyr and established tolerances for 

residues of that chemical. EPA is 

incorporating previously published 

sections from these rulemakings as 

described further in this rulemaking, as 

they remain unchanged. 

Toxicological Profile. For a discussion 

of the Toxicological Profile of triclopyr, 

see Unit III.A. of the final rule published 

in the Federal Register of February 25, 

2016 (81 FR 9353) (FRL–9941–87). 

Toxicological Points of Departure/ 

Levels of Concern. A summary of the 

toxicological endpoints and points of 

departure for triclopyr used for human 

risk assessment can be found in the 

document, ‘‘Triclopyr. Human Health 

Risk Assessment for Section 3 Use on 

Sugarcane’’ in docket ID EPA–HQ–OPP– 

2022–0890. As explained in the Food 

Quality Protection Act (FQPA) section 

below, the FQPA safety factor for shortand intermediate-term inhalation 

exposures has decreased from 10X to 1X 

since the February 25, 2016, final rule 

so the level of concern for short- and 

intermediate-term inhalation exposures 

is now 100. 

Exposure Assessment. EPA’s dietary 

exposure assessments have been 

updated to include the additional 

exposures from the petitioned-for 

tolerance. Acute and chronic dietary 

(food and drinking water) exposure and 

risk assessments were conducted using 

the Dietary Exposure Evaluation Model 

software using the Food Commodity 

Intake Database (DEEM–FCID) Version 

4.02. This software uses 2005–2010 food 

consumption data from the USDA’s 

National Health and Nutrition 

Examination Survey, What We Eat in 

America (NHANES/WWEIA). The acute 

dietary exposure assessment was 

unrefined, using tolerance-level 

residues for all registered and proposed 

commodities. The chronic dietary 

exposure assessment was slightly 

refined, using tolerance-level residues 

for all commodities except milk. An 

anticipated residue calculated from a 

recently submitted livestock feeding 

study was used for milk. HED default 

processing factors were used to estimate 

residues in processed commodities. 

Drinking water was incorporated 

directly into the dietary assessment. The 

acute and chronic dietary exposure 

assessments assumed 100% crop treated 

for all registered and proposed 

commodities. 

The Agency classified triclopyr as a 

‘‘Group D Chemical—unable to be 

classified as to human carcinogenicity.’’ 

This is based on marginal evidence of 

mammary tumors in female rats and 

mice and benign adrenal 

pheochromocytomas in male rats. There 

was no evidence of mutagenicity in a 

full battery of studies for triclopyr. 

Therefore, a cancer risk assessment was 

not conducted. The use of the chronic 

reference dose (RfD), which is derived 

from the most protective point of 

departure (POD) from the tox database, 

will adequately account for all chronic 

toxicity, including potential 

carcinogenicity that could result from 

exposure to triclopyr. A 100X 

uncertainty factor (10X for interspecies 

extrapolation and 10X for intraspecies 

variation) was incorporated into the 

chronic RfD. Since the FQPA SF has 

been reduced to 1X, the chronic 

population-adjusted dose (cPAD) is 

equal to the chronic RfD. 

Drinking water exposure. EPA revised 

the triclopyr drinking water assessment 

since the February 25, 2016, final rule 

as part of Registration Review using 

current models, newly submitted 

studies and changes in labels. The 

estimated drinking water concentrations 

(EDWCs) were higher for surface water 

sources than for ground water sources. 

The acute dietary exposure assessment 

used the highest 1-in-10-year acute 

EDWC of 758 ppb of triclopyr and the 

chronic dietary exposure assessment 

incorporated the highest 1-in-10-year 

chronic EDWC of 396 ppb of triclopyr. 

The drinking water models, and their 

descriptions are available at the EPA 

internet site: https://www.epa.gov/ 

pesticide-science-and-assessingpesticide-risks/models-pesticide-riskassessment. 

Non-occupational exposure. The 

proposed use on sugarcane does not 

involve applications by homeowners or 

commercial applicators in residential 

settings. Therefore, no new residential 

exposure is expected. The residential 

exposure assessment used the same 

assumptions as described in the 

February 25, 2016, final rule. 

Cumulative exposures. 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 triclopyr and any 

other substances. 3,5,6-trichloro-2- 

pyridinol, commonly known as TCP, is 

a metabolite of triclopyr, chlorpyrifos, 

and chlorpyrifos-methyl. Risk 

assessment of TCP was conducted in 

2002, which concluded that the acute 

and chronic dietary aggregate exposure 

estimates are below EPA’s level of 

concern. As TCP is not a residue of 

concern in plants and the proposed use 

on sugarcane will not result in any 

additional exposure to TCP, the results 

of the 2002 TCP assessment are still 

considered valid. For the purposes of 

this action, EPA has not assumed that 

triclopyr has a common mechanism of 

toxicity with other substances. 

Safety Factor for Infants and 

Children. 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 Act Safety 

Factor (FQPA 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. 

Prenatal and postnatal sensitivity. 

Offspring and developmental effects 

occurred in the presence of maternal 

and parental toxicity. In the twogeneration reproduction study with 

triclopyr acid, rare malformations, 

including exencephaly (brain protrudes 

outside of the skull) and ablepharia 

(absence of eyelids), were seen in rat 

pups at the mid- and high-doses (25 mg/ 

kg/day and 250 mg/kg/day, 

respectively). These malformations were 

considered, using a weight-of-evidence 

(WOE) approach, to be evidence of 

increased qualitative susceptibility. In 

the rat developmental toxicity study 

with triclopyr acid, cleft palate, 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 89, No. 40 / Wednesday, February 28, 2024 / Rules and Regulations 14593 

brachycephaly (flat head syndrome), 

and delayed ossification occurred at the 

highest dose tested (200 mg/kg/day) 

while the no-observed-adverse-effect 

level (NOAEL) for maternal toxicity was 

not established since clinical signs of 

severe toxicity due to the bolus 

administration of a low pH compound 

were seen at the lowest dose tested (50 

mg/kg/day). There were no other 

concerns for susceptibility identified in 

the other developmental studies where 

developmental and maternal effects 

were seen at 100 mg/kg/day and 300 

mg/kg/day in the rabbit and rat, 

respectively. 

Conclusion. EPA has determined that 

reliable data show the safety of infants 

and children would be adequately 

protected if the FQPA SF were reduced 

from 10X to 1X for all exposure 

scenarios based on the following 

considerations: 

1. The existing toxicological database 

is adequate for characterizing triclopyr 

toxicity and quantification of hazard for 

dietary and occupational exposures. The 

developmental toxicity studies in rats 

and rabbits and two-generation 

reproduction toxicity studies in rats are 

available to assess potential fetal/ 

offspring sensitivity; 

2. There is no evidence of 

neurotoxicity from triclopyr exposure; 

3. While there is evidence of 

increased qualitative susceptibility to 

offspring from triclopyr exposure in the 

two-generation reproduction toxicity 

study, the concern is low since effects 

are well-characterized with clearly 

established NOAEL/lowest-observedadverse-effect level (LOAEL) values, 

effects were seen in the presence of 

parental toxicity, and selected 

endpoints are protective of the observed 

effects; and 

4. There are no residual uncertainties 

with respect to exposure data. The 

dietary food exposure assessment 

utilizes tolerance-level residues 

(established or recommended) except 

milk (an anticipated residue was used 

for milk in the chronic assessment) and 

100% crop treated for all proposed/ 

established commodities. By using these 

assumptions, the acute and chronic 

exposures/risks will not be 

underestimated. 

The dietary drinking water 

assessment utilizes water concentration 

values generated by models and 

associated modeling parameters that are 

designed to provide conservative, 

health-protective, high-end estimates of 

water concentrations that will not likely 

be exceeded. The residential handler 

and post-application exposure 

assessments are based upon the 

residential standard operating 

procedures (SOPs) in conjunction with 

Pesticide Handlers Exposure Database 

unit exposures. The residential SOPs are 

based upon reasonable worst-case 

assumptions and are not expected to 

underestimate risk. These assessments 

of exposure are not likely to 

underestimate the resulting estimates of 

risk from exposure to triclopyr. 

Aggregate Risk and Determination of 

Safety. EPA determines whether acute 

and chronic dietary pesticide exposures 

are safe by comparing dietary exposure 

estimates to the acute populationadjusted dose (aPAD) and chronic PAD 

(cPAD). Short-, intermediate-, and 

chronic-term risks are evaluated by 

comparing the estimated total food, 

water, and residential exposure to the 

appropriate PODs to ensure that an 

adequate margin of exposure (MOE) 

exists. 

Acute dietary risks are below the 

Agency’s level of concern of 100% of 

the aPAD; they are 53% of the aPAD for 

females 13–49 years old and 8% of the 

aPAD for all infants, the most highly 

exposed population subgroup. No acute 

residential/recreational exposures are 

expected, so the acute aggregate risk is 

equivalent to the acute dietary risk and 

is not of concern. Chronic dietary risks 

are below the Agency’s level of concern 

of 100% of the cPAD; they are 46% of 

the cPAD for all infants, the most highly 

exposed population subgroup. No longterm residential exposures are expected, 

so the chronic aggregate risk is 

equivalent to the chronic dietary risk 

and is not of concern. 

For the short-term aggregate risk 

assessment, potential residential 

exposures were combined with food and 

drinking water exposures. Specifically, 

the short-term aggregate assessment for 

adults combines dietary (food + 

drinking water) exposures with handler 

inhalation exposures resulting from the 

registered turf use and the MOE is 410. 

For children 1 to <2 years old, the shortterm aggregate assessment combines 

dietary (food + drinking water) exposure 

with potential post-application 

incidental oral exposure resulting from 

the registered turf use and the MOE is 

360. For children 3 to <6 years old, the 

short-term aggregate assessment 

combines dietary (food + drinking 

water) exposure with potential postapplication inhalation and incidental 

oral swimmer exposure resulting from 

the registered aquatic use and the MOE 

is 120. As the short-term aggregate 

MOEs are greater than 100, the risks are 

not of concern. Although there are 

intermediate-term residential exposures, 

an intermediate-term aggregate was not 

separately assessed since: 1. the shortand intermediate-term points of 

departure are the same and 2. the shortterm aggregate provides a worst-case 

estimate of residential exposure. For 

these reasons, the short-term aggregate 

is protective of the longer-term 

exposures. 

As stated in Unit III.A. of the February 

25, 2016, final rule, EPA has determined 

that an aggregate exposure risk 

assessment for cancer risk is not 

required based on WOE conclusions on 

the marginal evidence of carcinogenicity 

in two adequate rodent carcinogenicity 

studies and the use of the chronic RfD 

which will adequately account for any 

potential carcinogenic effects. 

Therefore, based on the risk 

assessments and information described 

above, 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 triclopyr residues. More 

detailed information on this action can 

be found in the document titled 

‘‘Triclopyr. Human Health Risk 

Assessment for Section 3 Use on 

Sugarcane’’ in docket ID EPA–HQ–OPP– 

2022–0890. 

IV. Other Considerations 

A. Analytical Enforcement Methodology 

For details about the analytical 

enforcement methodology, see Unit 

IV.A. of the final rule published in the 

Federal Register of February 25, 2016. 

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 any 

MRLs for triclopyr. 

C. Revisions to Petitioned-For 

Tolerances 

EPA is not removing the established 

time-limited tolerance for residues of 

triclopyr in or on sugarcane, cane at 40 

ppm. The use pattern in the emergency 

exemption for triclopyr on sugarcane is 

different than the Section 3 use 

supported by this tolerance rule and 

there may be sugarcane in the channels 

of trade with higher residues from use 

under the emergency exemption. 

V. Conclusion 

Therefore, a tolerance is established 

for residues of the herbicide triclopyr, 

including its metabolites and 

degradates, in or on sugarcane, cane at 


ddrumheller on DSK120RN23PROD with RULES1
14594 Federal Register / Vol. 89, No. 40 / Wednesday, February 28, 2024 / Rules and Regulations 

0.04 ppm, resulting from the application 

of the butoxyethyl ester of triclopyr, 

triethylamine salt of triclopyr, or 

choline salt of triclopyr. 

VI. Statutory and Executive Order 

Reviews 

This action establishes a tolerance 

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 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 

rule’’ as defined by 5 U.S.C. 804(2).

SUPPLEMENTARY INFORMATION: The 

United States is a member of the InterAmerican Tropical Tuna Commission 

(IATTC), which was established under 

the Convention for the Establishment of 

an IATTC signed in 1949 (1949 

Convention). The 1949 Convention 

provides an international agreement to 

ensure the effective international 

conservation and management of highly 

migratory species of fish in the IATTC 

Convention Area. In 2003, the IATTC 

updated the 1949 Convention through 

the adoption of the Convention for the 

Strengthening of the IATTC Established 

by the 1949 Convention between the 

United States of America and the 

Republic of Costa Rica (Antigua 

Convention). The IATTC Convention 

Area, as amended by the Antigua 

Convention, includes the waters of the 

EPO bounded by the coast of the 

Americas, the 50° N and 50° S parallels, 

and the 150° W meridian. 

Fishing for PBF in the EPO is 

managed, in part, under the Tuna 

Conventions Act of 1950, as amended 

(the Act), 16 U.S.C. 951 et seq. Under 

the Act, NMFS must publish regulations 

to carry out recommendations and 

decisions of the IATTC in consultation 

with the Department of State. 

Regulations implementing conservation 

and management measures for tuna and 

tuna-like species in the EPO are codified 

at 50 CFR part 300, subpart C.
