Ammonium Acetate; Exemption From 

the Requirement of a Tolerance 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: This regulation establishes an 

exemption from the requirement of a 

tolerance for residues of ammonium 

acetate (CAS No. 631–61–8) when used 

as an inert ingredient (buffering agent) 

limited to 15% in pesticide 

formulations applied to pre-harvested 

crops. Exponent Inc., 1150 Connecticut 

Ave., Suite 1100, Washington, DC 20036 

on behalf of the Gowan Company LLC., 

370 South Main Street, Yuma, AZ 85364 

submitted a petition to EPA under the 

Federal Food, Drug, and Cosmetic Act 

(FFDCA), requesting establishment of an 

exemption from the requirement of a 

tolerance. This regulation eliminates the 

need to establish a maximum 

permissible level for residues of 

ammonium acetate.

II. Petition for Exemption 

In the Federal Register of December 

30, 2013 (78 FR79359) (FRL–9903–69), 

EPA issued a document pursuant to 

FFDCA section 408, 21 U.S.C. 346a, 

announcing the filing of a pesticide 

petition (PP IN–10604) by Exponent 

Inc., 1150 Connecticut Ave., Suite 1100, 

Washington, DC 20036, on behalf of the 

Gowan Company LLC., 370 South Main 

Street, Yuma, AZ 85364. The petition 

requested that 40 CFR 180.920 be 

amended by establishing an exemption 

from the requirement of a tolerance for 

residues of ammonium acetate (CAS No. 

631–61–8) when used as an inert 

ingredient in pesticide formulations 

applied to crops pre-harvest and limited 

to 15% in pesticide formulations. That 

document referenced a summary of the 

petition prepared by Exponent Inc., on 

behalf of the Gowan Company LLC, the 

petitioner, which is available in the 

docket, http://www.regulations.gov. No 

comments were received on the notice 

of filing. EPA’s response to these 

comments is discussed in Unit V.C. 

III. Inert Ingredient Definition 

Inert ingredients are all ingredients 

that are not active ingredients as defined 

in 40 CFR 153.125 and include, but are 

not limited to, the following types of 

ingredients (except when they have a 

pesticidal efficacy of their own): 

Solvents such as alcohols and 

hydrocarbons; surfactants such as 

polyoxyethylene polymers and fatty 

acids; carriers such as clay and 

diatomaceous earth; thickeners such as 

carrageenan and modified cellulose; 

wetting, spreading, and dispersing

agents; propellants in aerosol 

dispensers; microencapsulating agents; 

and emulsifiers. The term ‘‘inert’’ is not 

intended to imply nontoxicity; the 

ingredient may or may not be 

chemically active. Generally, EPA has 

exempted inert ingredients from the 

requirement of a tolerance based on the 

low toxicity of the individual inert 

ingredients. 

IV. Aggregate Risk Assessment and 

Determination of Safety 

Section 408(c)(2)(A)(i) of FFDCA 

allows EPA to establish an exemption 

from the requirement for 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. . . .’’ 

EPA establishes exemptions from the 

requirement of a tolerance only in those 

cases where it can be clearly 

demonstrated that the risks from 

aggregate exposure to pesticide 

chemical residues under reasonably 

foreseeable circumstances will pose no 

appreciable risks to human health. In 

order to determine the risks from 

aggregate exposure to pesticide inert 

ingredients, the Agency considers the 

toxicity of the inert in conjunction with 

possible exposure to residues of the 

inert ingredient through food, drinking 

water, and through other exposures that 

occur as a result of pesticide use in 

residential settings. If EPA is able to 

determine that a finite tolerance is not 

necessary to ensure that there is a 

reasonable certainty that no harm will 

result from aggregate exposure to the 

inert ingredient, an exemption from the 

requirement of a tolerance may be 

established. 

Consistent with FFDCA section 

408(c)(2)(A), and the factors specified in 

FFDCA section 408(c)(2)(B), 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 ammonium 

acetate including exposure resulting 

from the exemption established by this 

action. EPA’s assessment of exposures 

and risks associated with ammonium 

acetate follows. 

A. Toxicological Profile 

EPA has evaluated the available 

toxicity data and considered their 

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. Specific 

information on the studies received and 

the nature of the adverse effects caused 

by ammonium acetate as well as the noobserved-adverse-effect-level (NOAEL) 

and the lowest-observed-adverse-effectlevel (LOAEL) from the toxicity studies. 

Ammonium acetate is an ammonium 

salt of acetic acid. In aqueous solutions 

acetic acid and its salt ammonium 

acetate dissociate into the acetate anion 

(CH3COO-) and the respective cations 

(H+ and NH4+). The cations and 

ammonia (also a human metabolite) are 

physiological components of the human 

body. The chemical structures, physicalchemical properties, environmental fate 

behavior, and aquatic and mammalian 

toxicity of ammonium acetate and acetic 

acid are similar. Since limited data are 

available on ammonium acetate, toxicity 

data on acetic acid were used to 

represent toxicity due to exposure to 

ammonium acetate. 

Acetic acid is of low acute dermal and 

inhalation toxicity in rats. It causes 

dermal irritation in mice and is 

corrosive in rabbits. It was also irritating 

in the eyes of rabbits. Although reduced 

body weight was observed at 390 mg/kg/ 

day in a 90-day oral toxicity study in the 

rat, the reduction in weight gain was 

likely attributed to reduced appetite and 

food consumption observed in the 

study. Therefore, this is not considered 

an adverse effect. Although increased 

spleen weight was observed at 23–31 

ppm (equivalent to 15–19 mg/kg/day) of 

acetic acid in a toxicity study in rats via 

the inhalation route of exposure, there 

is no concern for potential 

immunotoxicity. The Agency considers 

that this effect is due to red blood cell 

destruction rather than an immunotoxic 

response. Fetal susceptibility was not 

observed in several developmental 

studies in rats, mice and rabbits. Neither 

maternal nor developmental toxicity 

was not observed up to 1,600 mg/kg/

day. It is not mutagenic in an Ames test 

nor is it clastogenic in a cytogenetic 

assay with Chinese hamster ovary K1 

cells. It is not carcinogenic. In an eight 

month cancer study, tumors were not 

observed in rats at 60 mg/kg/day. While 

evidence of potential neurotoxicity was 

observed in a literature study in rats 

conducted by Sapute et al.1, a second 

study in rats showed no indication of 

systemic toxicity, neurotoxicity, 

neuropathological or histological lesions 

at the same dose that was previously 

tested, 100 mg/kg/day. Since the second 

study (MRID 49703201) 2 was conducted 

according to the Organization for 

Economic Co-operation and 

Development (OECD) and good 

laboratory practice (GLP) guidelines, it 

was considered to accurately represent 

the neurotoxic potential for ammonium 

acetate. 

As noted above, acetic acid undergoes 

dissociation to the acetate anion and the 

H+ cations in aqueous media at pHs 

commonly found in the environment. 

Also, it is a naturally-occurring 

substance in plants and animals. In 

aerobic metabolism, acetic acid (as 

acetate) is a metabolite that combines 

with Co-enzyme A to form acetyl Co-A 

which subsequently enters into the 

Citric Acid Cycle, a common metabolic 

pathway in which food molecules are 

broken down to form energy. A major 

function of the Citric Acid Cycle is the 

oxidation of acetate. In animals, acetate 

is obtained from the breakdown of 

glucose molecules. 

Specific information on the studies 

received and the nature of the adverse 

effects caused by acetic acid as well as 

the no observed adverse effect level 

(NOAEL) and the lowest observed 

adverse effect level (LOAEL) from the 

toxicity studies can be found at http:// 

www.regulations.gov in the document

B. Toxicological Points of Departure/

Levels of Concern 

In an aqueous environment, 

ammonium acetate dissociates to acetic 

acid and its salt. Therefore, it is 

appropriate to expect toxicity due to 

exposure to ammonium acetate to be 

similar to that of acetic acid. Therefore, 

based on the absence of a toxicological 

endpoint of concern via dietary route of 

exposure for acetic acid, its regulatory 

history, and no new toxicological data 

to indicate concern regarding previous 

decisions, a qualitative assessment was 

appropriate for ammonium acetate for 

all pathways of human exposure (food, 

drinking water, and residential). A 

potential endpoint of concern for the 

inhalation route of exposure was 

identified in a toxicity study. Increased 

spleen weight due to red blood cell 

destruction was observed at 23–31 ppm 

(equivalent to 15–19 mg/kg/day) of 

acetic acid in rats. However, according 

to the American Conference of 

Governmental Industrial Hygenists, Inc. 

(ACGIH), the threshold limit value 

(TLV) for occupational exposure to 

acetic acid is 10 ppm via inhalation. 

Residential exposure to the proposed 

use of ammonium acetate via inhalation 

is not expected to exceed the TLV limit 

of 10 ppm because the residential use 

pattern would result in drastically lower 

opportunities for inhalation exposure 

than allowed occupational use patterns, 

which are limited to 10 ppm. In 

addition, residential exposure will be 

much lower because exposure is 

expected to occur for shorter periods to 

diluted acetic acid as compared to 

workers who are exposed for 8 hours 

continuously, to more concentrated 

acetic acid. Therefore, a qualitative 

assessment was conducted with regard 

to inhalation exposure. 

C. Exposure Assessment 

1. Dietary exposure from food and 

feed uses. In evaluating dietary 

exposure to ammonium acetate, EPA 

considered exposure under the 

proposed exemption from the 

requirement of a tolerance. EPA 

assessed dietary exposures from 

ammonium acetate in food as follows: 

Under this exemption from the 

requirement of a tolerance, residues of 

this ammonium acetate may be found 

on foods from crops that were treated 

with pesticide formulations containing 

ammonium acetate. However, a 

quantitative dietary exposure 

assessment was not conducted since an 

endpoint for risk assessment was not 

identified. 

2. Dietary exposure from drinking 

water. Since a hazard endpoint of 

concern was not identified for the acute 

and chronic dietary assessment, a 

quantitative dietary exposure risk 

assessment for drinking water was not 

conducted, although exposures may be 

expected from use on food crops. 

3. From non-dietary exposure. The 

term ‘‘residential exposure’’ is used in 

this document to refer to nonoccupational, non-dietary exposure 

(e.g., textiles (clothing and diapers), 

carpets, swimming pools, and hard 

surface disinfection on walls, floors, 

tables). 

Ammonium acetate may be used in 

pesticide products and non-pesticide 

products that may be used around the 

home. Based on the discussion in Unit 

IV.B., a quantitative residential 

exposure assessment for ammonium 

acetate was not conducted. 

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.’’ 

EPA has not found ammonium acetate 

to share a common mechanism of 

toxicity with any other substances, and 

ammonium acetate does not appear to 

produce a toxic metabolite produced by 

other substances. For the purposes of 

this tolerance action, therefore, EPA has 

assumed that ammonium acetate does 

not have a common mechanism of 

toxicity with other substances. For 

information regarding EPA’s efforts to 

determine which chemicals have a 

common mechanism of toxicity and to 

evaluate the cumulative effects of such 

chemicals, see EPA’s Web site at http:// 

www.epa.gov/pesticides/cumulative. 

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 

FQPA 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. 

As part of its qualitative assessment, 

the Agency did not use safety factors for 

assessing risk, and no additional safety 

factor is needed for assessing risk to 

infants and children. Based on an 

assessment of ammonium acetate and its 

chemical properties, EPA has concluded 

that there are no toxicological endpoints 

of concern for the U.S. population, 

including infants and children. 

E. Aggregate Risks and Determination of 

Safety 

Because no toxicological endpoints of 

concern were identified, EPA concludes 

that aggregate exposure to residues of 

ammonium acetate will not pose a risk 

to the U.S. population, including infants 

and children, and that there is a 

reasonable certainty that no harm will 

result to the general population, or to 

infants and children from aggregate 

exposure to ammonium acetate 

residues. 

V. Analytical Enforcement Methodology 

An analytical method is not required 

for enforcement purposes since the 

Agency is establishing an exemption 

from the requirement of a tolerance. 

EPA is establishing a limitation on the 

amount of ammonium acetate that may 

be used in pesticide formulations. The 

limitation will be enforced through the 

pesticide registration process under the 

Federal Insecticide, Fungicide, and 

Rodenticide Act (FIFRA), 7 U.S.C. 136 

et seq. EPA will not register any 

pesticide formulation used on crops for 

sale or distribution containing 

ammonium acetate at ready for use enduse concentrations exceeding 15%. 

VI. Conclusions 

Therefore, an exemption from the 

requirement of a tolerance is established 

under 40 CFR 180.920 for ammonium 

acetate (CAS No. 631–61–8) when used 

as an inert ingredient (buffering agent) 

in pesticide formulations applied to 

crops pre-harvest and limited to 15% in 

the end use formulation. 

VII. Statutory and Executive Order 

Reviews 

This action establishes a tolerance 

exemption 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 


asabaliauskas on DSK5VPTVN1PROD with RULES
79708 Federal Register / Vol. 80, No. 246 / Wednesday, December 23, 2015 / Rules and Regulations 

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 exemption 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). 

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).
