Background and Statutory Findings In the Federal Register of May 2, 2012, (77 FR 25954) (FRL–9346–1), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance petition (PP 1E7933) by Exponent Inc., 1150 Connecticut Ave. NW., Suite 1100, Washington, DC 20036, on behalf of Ecolab, Inc., 370 N. Wabasha Street, St. Paul, MN 55102. The petition requested that 40 CFR part 180.940(a) be amended by establishing an exemption from the requirement of a tolerance for residues of aluminum sulfate for use as an inert ingredient in antimicrobial pesticide formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils at a maximum end use concentration not to exceed 50 parts per million (ppm). That document referenced a summary of the petition prepared by the petitioner Exponent, E:\FR\FM\05JNR1.SGM 05JNR1 Federal Register / Vol. 80, No. 108 / Friday, June 5, 2015 / Rules and Regulations Inc., which is available in the docket, https://www.regulations.gov. There were no comments received in response to the notice of filing. 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 exemption is ‘‘safe.’’ Section 408(c)(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. Pursuant to FFDCA section 408(c)(2)(B), in establishing or maintaining in effect an exemption from the requirement of a tolerance, EPA must take into account the factors set forth in FFDCA section 408(b)(2)(C), which 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 performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. First, EPA determines the toxicity of pesticides. Second, EPA examines exposure to the pesticide through food, drinking water, and through other exposures that occur as a result of pesticide use in residential settings. mstockstill on DSK4VPTVN1PROD with RULES III. Toxicological Profile Consistent with FFDCA section 408(b)(2)(D), EPA has reviewed the available scientific data and other relevant information in support of this action and considered its validity, completeness and reliability and the relationship of this information 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. The nature of the toxic effects caused by aluminum sulfate is discussed in this unit. The acute oral toxicity of aluminum sulfate is low. The acute oral lethal dose (LD)50 in male rats is >5,000 milligram/ kilogram (mg/kg). No acute dermal or inhalation toxicity studies are available on aluminum sulfate. It is not a dermal irritant and is minimally irritating to the VerDate Sep<11>2014 17:17 Jun 04, 2015 Jkt 235001 eyes. No skin sensitization studies are available. The points of departure (PODs) used for the chronic and short-term risk assessments for aluminum sulfate were based on an Organization for Economic Cooperation and Development (OECD) Guideline 416, 2-generation rat oral reproduction study with aluminum sulfate (equivalent to OCSPP Harmonized Test Guideline 870.3800) in which the lowest-observed-adverseeffect level (LOAEL) was 188 milligram/ kilogram/day (mg/kg/day) (equivalent to 37 mg aluminum (Al)/kg/day) based on decreased body weight from pups and parents and delay in vaginal opening. The no-observed-adverse-effect level (NOAEL) was 41 mg/kg/day aluminum sulfate (equivalent to 8.06 mg Al/kg/ day. Apart from the 2-generation rat oral reproduction study described above, limited data are available on aluminum sulfate. However, since ingested aluminum sulfate will readily dissociate in the stomach to aluminum (as will many other aluminum compounds), toxicology data on aluminum compounds as well as aluminum sulfate are considered in determining the acceptability and completeness of the toxicological data relevant to aluminum sulfate. Aluminum compounds have been evaluated by the Agency for Toxic Substances and Disease Registry (ASTDR, 2008) and as part of the toxicological profile of aluminum, ASTDR notes that ‘‘There is a rather extensive database on the oral toxicity of aluminum in animals. These studies clearly identify the nervous system as the most sensitive target of aluminum toxicity and most of the animal studies have focused on neurotoxicity and neurodevelopmental toxicity. Other adverse effects that have been observed in animals orally exposed to aluminum include impaired erythropoiesis in rats exposed to 230 mg Al/kg/day and higher; erythrocyte damage (as evidenced by decreases in hemoglobin, hematocrit, and erythrocyte osmotic fragility, and altered erythrocyte morphology) in rats exposed to 230 mg Al/kg/day and higher; increased susceptibility to infection in mouse dams exposed to 155 mg Al/kg/day; delays in pup maturation following exposure of rats to 53 mg Al/kg/day; and decreases in pup body weight gain in rats and mice exposed to 103 mg Al/kg/ day and higher. Oral studies in rats and mice have not found significant histopathological changes in the brain under typical exposure conditions; however, altered myelination was found in the spinal cord of mouse pups PO 00000 Frm 00065 Fmt 4700 Sfmt 4700 32035 exposed to 330 mg Al/kg/day on gestation day 1 through postnatal day 35. Overt signs of neurotoxicity are rarely reported at the doses tested in the available animal studies (≤330mg Al/kg/ day for bioavailable aluminum compounds); rather, exposure to these doses is associated with subtle neurological effects detected with neurobehavioral performance tests. Significant alterations in motor function, sensory function, and cognitive function have been detected following exposure to adult or weanling rats and mice or following gestation and/or lactation exposure of rats and mice to aluminum lactate, aluminum nitrate, and aluminum chloride. The most consistently affected performance tests were forelimb and/or hindlimb grip strength, spontaneous motor activity, thermal sensitivity, and startle responsiveness. Significant impairments in cognitive function have been observed in some studies, although this has not been found in other studies even at higher doses. Adverse neurological effects have been observed in rats and mice at doses of 100–200 mg Al/kg/day and neurodevelopmental effects have been observed in rats and mice at doses of 103–330 mg Al/kg/day.’’ There are no available carcinogenicity studies with aluminum sulfate; however, in a cancer study with aluminum potassium sulfate, there were no exposure-related increased incidences of tumors, other proliferative lesions, or non-neoplastic lesions in B6C3F1 mice that ingested ≤979 mg Al/ kg/day as aluminum potassium sulfate in the diet for 20 months. Based on this information, aluminum sulfate is not expected to be a carcinogen. Specific information on the studies received and the nature of the adverse effects caused by aluminum sulfate as well as the NOAEL and the LOAEL from the toxicity studies are discussed in ‘‘Aluminum Sulfate: Human Health Risk Assessment and Ecological Effects Assessment for Proposed Exemption from the Requirement for a Tolerance When Used as an Inert Ingredient in Antimicrobial Pesticide Formulations Applied to Food-Contact Surfaces’’ in docket ID number EPA–HQ–OPP–2012– 0267. A. Toxicological Points of Departure/ Levels of Concern Once a pesticide’s toxicological profile is determined, EPA identifies toxicological 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 E:\FR\FM\05JNR1.SGM 05JNR1 32036 Federal Register / Vol. 80, No. 108 / Friday, June 5, 2015 / Rules and Regulations mstockstill on DSK4VPTVN1PROD with RULES for derivation of reference values for risk assessment. PODs are developed based on a careful analysis of the doses in each toxicological study to determine the dose at which the NOAEL and the LOAEL are identified. 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 RfD—and a safe margin of exposure (MOE). For non-threshold 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/ pesticides/factsheets/riskassess.htm. A summary of the toxicological endpoints for aluminum sulfate used for human risk assessment is discussed below: Acute Dietary Endpoint. No appropriate endpoint was identified from any of the aluminum sulfate studies in the database, including developmental toxicity studies in the rat. Consequently, EPA determined that there was no basis for selecting a dose and endpoint for an acute POD for the general population or females 13–49 years old. Chronic Dietary Endpoint. A 2generation reproduction study of aluminum sulfate in rats was considered critical in establishing the POD for chronic dietary risk assessment. The study supports a NOAEL of 41 mg/kg/ day and a LOAEL of 188 mg/kg/day for decreased body weight in parents and pups and a delay in vaginal opening and should be used as the POD for all durations and exposure scenarios. An uncertainty factor (UF) of 100X (10X for interspecies extrapolation and 10X for intraspecies variation) is applied to obtain a chronic reference dose (cRfD) of 0.41 mg/kg/day. The Food Quality Protection Act (FQPA) factor is reduced to 1X. The chronic population adjusted dose (cPAD) is 0.41 mg/kg/day. This cPAD is protective of potential neurotoxicological effects of aluminum compounds. B. Exposure Assessment 1. Dietary exposure from food and feed uses. Exposures to aluminum sulfate can occur following ingestion of foods with residues from food-contact surface sanitizing solutions for public eating places, treated dairy- and foodprocessing equipment and utensils as well as pre-harvest crop uses. In VerDate Sep<11>2014 17:17 Jun 04, 2015 Jkt 235001 evaluating dietary exposure to aluminum sulfate, EPA considered exposure under the requested exemption from the requirement of a tolerance as well as exposures from existing uses of aluminum sulfate under the extant exemption from the requirement of a tolerance under 40 CFR 180.920. EPA assessed dietary exposures from aluminum sulfate in food as follows: i. Acute exposure. Quantitative acute dietary exposure and risk assessments are performed for a food-use pesticide chemical, if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a 1-day or single exposure. No such effects were identified in the toxicological studies for aluminum sulfate; therefore, a quantitative acute dietary exposure assessment is unnecessary. ii. Chronic exposure. The chronic dietary exposure assessment for this inert ingredient utilizes the Dietary Exposure Evaluation Model Food Commodity Intake Database (DEEM– FCID), Version 3.16, EPA, which includes food consumption information from the U.S. Department of Agriculture’s National Health and Nutrition Examination Survey, ‘‘What We Eat In America’’, (NHANES/ WWEIA). This dietary survey was conducted from 2003 to 2008. In the absence of actual residue data, the inert ingredient evaluation is based on a highly conservative model that assumes that the residue level of the inert ingredient would be no higher than the highest established tolerance for an active ingredient on a given commodity. Implicit in this assumption is that there would be similar rates of degradation between the active and inert ingredient (if any) and that the concentration of inert ingredient in the scenarios leading to these highest of tolerances would be no higher than the concentration of the active ingredient. The model assumes 100 percent crop treated (PCT) for all crops and that every food eaten by a person each day has tolerance-level residues. A complete description of the general approach taken to assess inert ingredient risks in the absence of residue data is contained in the memorandum entitled ‘‘Alkyl Amines Polyalkoxylates (Cluster 4): Acute and Chronic Aggregate (Food and Drinking Water) Dietary Exposure and Risk Assessments for the Inerts’’ (D361707, S. Piper, 2/25/09) and can be found at https://www.regulations.gov in docket ID number EPA–HQ–OPP–2008–0738. Additionally, a dietary exposure assessment of aluminum sulfate resulting from the requested use in antimicrobial food-contact surface PO 00000 Frm 00066 Fmt 4700 Sfmt 4700 sanitizing solutions was conservatively assumed that 100% of the diet results from food treated with food-contact surface sanitizers and that 100% of the sanitizing solution is transferred into food. A highly conservative model based on FDA assumptions regarding transfer of food contact sanitizing solution residues to food is utilized. The dietary exposure values derived from both the conservative model used to estimate residues from application to growing crops are combined with the exposures estimated from the antimicrobial food-contact sanitizer uses. iii Cancer. Based on the data summarized in Unit III.A., EPA has concluded that aluminum sulfate is not expected to pose a cancer risk to humans. Therefore, a dietary exposure assessment for the purpose of assessing cancer risk is unnecessary. 2. Dietary exposure from drinking water. For the purpose of the screening level dietary risk assessment to support this request for an exemption from the requirement of a tolerance for aluminum sulfate, a conservative drinking water concentration value of 100 parts per billion (ppb) based on screening level modeling was used to assess the contribution to drinking water for the chronic dietary risk assessment of aluminum sulfate. This value was directly entered into the dietary exposure model. 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). There are no registered pesticide products containing aluminum sulfate as an inert ingredient for any specific use patterns that would result in residential exposure. 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 aluminum sulfate to share a common mechanism of toxicity with any other substances, and aluminum sulfate does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that aluminum sulfate does not E:\FR\FM\05JNR1.SGM 05JNR1 Federal Register / Vol. 80, No. 108 / Friday, June 5, 2015 / Rules and Regulations mstockstill on DSK4VPTVN1PROD with RULES 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 https://www.epa.gov/pesticides/ cumulative. C. 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 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. 2. Prenatal and postnatal sensitivity. In a 2-generation reproduction toxicity study, there was no evidence of increased susceptibility of infants and children to aluminum sulfate. In this study, the offspring and parental toxicity NOAEL was 41 mg/kg/day based on decreased weight gain in offspring, decreased body weight in parental animals, and a delay in vaginal opening seen at the LOAEL of 188 mg/ kg/day. 3. Conclusion. EPA has determined that reliable data show the safety of infants and children would be adequately protected if the FQPA SF were reduced to 1X. That decision is based on the following findings: i. The toxicity database for aluminum sulfate includes a 2-generation reproduction study, as well as chronic/ carcinogenicity studies, mutagenicity studies, neurotoxicity studies and developmental neurotoxicity studies on other related aluminum compounds. The Agency concludes that for this ingredient, the results of these studies provide a reliable basis for assessing the range of potential effects to infants and children, such that the Agency has determined that no additional data are necessary at this time to evaluate effects to infants and children. ii. There are available data on neurotoxicity and developmental neurotoxicity on aluminum compounds. The point of departure selected for risk assessment is based on a 2-generation rat reproductive toxicity study with VerDate Sep<11>2014 17:17 Jun 04, 2015 Jkt 235001 aluminum sulfate, in which adverse effects were identified at dose levels below the dose levels at which neurotoxic effects or developmental neurotoxicological effects were observed and is therefore protective of those effects; no additional UFs are required to account for neurotoxicity. iii. There is no evidence of increased susceptibility due to pre-or post-natal exposure to aluminum in infants and children. iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100 PCT and residues equivalent to the highest established tolerance-level residues for every food commodity. EPA made conservative (protective) assumptions utilizing a 100 ppb default value in the ground and surface water modeling used to assess exposure to aluminum sulfate in drinking water. In addition, highly conservative assumptions were utilized in assessing exposures to aluminum sulfate resulting from the proposed use in food-contact surface antimicrobial pesticide formulations. These assessments will not underestimate the exposure and risks posed by aluminum sulfate. D. 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 PAD (aPAD) and cPAD. For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE exists. 1. Acute risk. An acute aggregate risk assessment takes into account acute exposure estimates from dietary consumption of food and drinking water. No adverse effect resulting from a single oral exposure was identified, therefore, an acute dietary exposure assessment was not conducted. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to aluminum sulfate from food and water will utilize 6.7% of the cPAD for children 1–2 years old, the population group receiving the greatest exposure. 3. Short-term and intermediate-term risk. Short-term and intermediate-term aggregate exposure takes into account short-term residential exposure plus PO 00000 Frm 00067 Fmt 4700 Sfmt 4700 32037 chronic exposure to food and water (considered to be a background exposure level). A short-term/ intermediate-term adverse effect was identified; however, aluminum sulfate is not used as inert ingredient in any pesticide product registered for any use patterns that would result in short-term or intermediate-term residential exposure. Because there is no short-term or intermediate-term residential exposure and chronic dietary exposure has already been assessed under the appropriately protective cPAD (which is at least as protective as the POD used to assess short-term risk), no further assessment of short-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating short-term risk for aluminum sulfate. 4. Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in a rodent carcinogenicity study with aluminum potassium sulfate, aluminum sulfate is not expected to pose a cancer risk to humans. 5. Determination of safety. Based on these risk assessments, 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 aluminum sulfate residues. VII. Other Considerations A. 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 without any numerical limitation. EPA is establishing a limitation on the amount of aluminum sulfate that may be used in food-contact surface antimicrobial applications. That 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 foodcontact surface antimicrobial applications for sale or distribution that contains greater than 50 ppm of aluminum sulfate by weight. VIII. Conclusion Therefore, an exemption is established for residues of aluminum sulfate for use as an inert ingredient in antimicrobial pesticide formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils at a maximum end use concentration not to exceed 50 ppm.

Statutory and Executive Order Reviews This action establishes an exemption from the requirement of 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 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).

II. Background and Statutory Findings

    In the Federal Register of May 2, 2012, (77 FR 25954) (FRL-9346-1), 
EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 
346a(d)(3), announcing the filing of a pesticide tolerance petition (PP 
1E7933) by Exponent Inc., 1150 Connecticut Ave. NW., Suite 1100, 
Washington, DC 20036, on behalf of Ecolab, Inc., 370 N. Wabasha Street, 
St. Paul, MN 55102. The petition requested that 40 CFR part 180.940(a) 
be amended by establishing an exemption from the requirement of a 
tolerance for residues of aluminum sulfate for use as an inert 
ingredient in antimicrobial pesticide formulations applied to food-
contact surfaces in public eating places, dairy-processing equipment, 
and food-processing equipment and utensils at a maximum end use 
concentration not to exceed 50 parts per million (ppm). That document 
referenced a summary of the petition prepared by the petitioner 
Exponent,

[[Page 32035]]

Inc., which is available in the docket, https://www.regulations.gov. 
There were no comments received in response to the notice of filing.
    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 exemption is ``safe.'' Section 408(c)(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. Pursuant to FFDCA section 408(c)(2)(B), in 
establishing or maintaining in effect an exemption from the requirement 
of a tolerance, EPA must take into account the factors set forth in 
FFDCA section 408(b)(2)(C), which 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 performs a number of analyses to determine the risks from 
aggregate exposure to pesticide residues. First, EPA determines the 
toxicity of pesticides. Second, EPA examines exposure to the pesticide 
through food, drinking water, and through other exposures that occur as 
a result of pesticide use in residential settings.

III. Toxicological Profile

    Consistent with FFDCA section 408(b)(2)(D), EPA has reviewed the 
available scientific data and other relevant information in support of 
this action and considered its validity, completeness and reliability 
and the relationship of this information 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. The nature of the toxic effects caused by 
aluminum sulfate is discussed in this unit.
    The acute oral toxicity of aluminum sulfate is low. The acute oral 
lethal dose (LD)50 in male rats is >5,000 milligram/kilogram 
(mg/kg). No acute dermal or inhalation toxicity studies are available 
on aluminum sulfate. It is not a dermal irritant and is minimally 
irritating to the eyes. No skin sensitization studies are available.
    The points of departure (PODs) used for the chronic and short-term 
risk assessments for aluminum sulfate were based on an Organization for 
Economic Cooperation and Development (OECD) Guideline 416, 2-generation 
rat oral reproduction study with aluminum sulfate (equivalent to OCSPP 
Harmonized Test Guideline 870.3800) in which the lowest-observed-
adverse-effect level (LOAEL) was 188 milligram/kilogram/day (mg/kg/day) 
(equivalent to 37 mg aluminum (Al)/kg/day) based on decreased body 
weight from pups and parents and delay in vaginal opening. The no-
observed-adverse-effect level (NOAEL) was 41 mg/kg/day aluminum sulfate 
(equivalent to 8.06 mg Al/kg/day.
    Apart from the 2-generation rat oral reproduction study described 
above, limited data are available on aluminum sulfate. However, since 
ingested aluminum sulfate will readily dissociate in the stomach to 
aluminum (as will many other aluminum compounds), toxicology data on 
aluminum compounds as well as aluminum sulfate are considered in 
determining the acceptability and completeness of the toxicological 
data relevant to aluminum sulfate.
    Aluminum compounds have been evaluated by the Agency for Toxic 
Substances and Disease Registry (ASTDR, 2008) and as part of the 
toxicological profile of aluminum, ASTDR notes that ``There is a rather 
extensive database on the oral toxicity of aluminum in animals. These 
studies clearly identify the nervous system as the most sensitive 
target of aluminum toxicity and most of the animal studies have focused 
on neurotoxicity and neurodevelopmental toxicity. Other adverse effects 
that have been observed in animals orally exposed to aluminum include 
impaired erythropoiesis in rats exposed to 230 mg Al/kg/day and higher; 
erythrocyte damage (as evidenced by decreases in hemoglobin, 
hematocrit, and erythrocyte osmotic fragility, and altered erythrocyte 
morphology) in rats exposed to 230 mg Al/kg/day and higher; increased 
susceptibility to infection in mouse dams exposed to 155 mg Al/kg/day; 
delays in pup maturation following exposure of rats to 53 mg Al/kg/day; 
and decreases in pup body weight gain in rats and mice exposed to 103 
mg Al/kg/day and higher. Oral studies in rats and mice have not found 
significant histopathological changes in the brain under typical 
exposure conditions; however, altered myelination was found in the 
spinal cord of mouse pups exposed to 330 mg Al/kg/day on gestation day 
1 through postnatal day 35. Overt signs of neurotoxicity are rarely 
reported at the doses tested in the available animal studies (<=330mg 
Al/kg/day for bioavailable aluminum compounds); rather, exposure to 
these doses is associated with subtle neurological effects detected 
with neurobehavioral performance tests. Significant alterations in 
motor function, sensory function, and cognitive function have been 
detected following exposure to adult or weanling rats and mice or 
following gestation and/or lactation exposure of rats and mice to 
aluminum lactate, aluminum nitrate, and aluminum chloride. The most 
consistently affected performance tests were forelimb and/or hindlimb 
grip strength, spontaneous motor activity, thermal sensitivity, and 
startle responsiveness. Significant impairments in cognitive function 
have been observed in some studies, although this has not been found in 
other studies even at higher doses. Adverse neurological effects have 
been observed in rats and mice at doses of 100-200 mg Al/kg/day and 
neurodevelopmental effects have been observed in rats and mice at doses 
of 103-330 mg Al/kg/day.''
    There are no available carcinogenicity studies with aluminum 
sulfate; however, in a cancer study with aluminum potassium sulfate, 
there were no exposure-related increased incidences of tumors, other 
proliferative lesions, or non-neoplastic lesions in B6C3F1 mice that 
ingested <=979 mg Al/kg/day as aluminum potassium sulfate in the diet 
for 20 months. Based on this information, aluminum sulfate is not 
expected to be a carcinogen.
    Specific information on the studies received and the nature of the 
adverse effects caused by aluminum sulfate as well as the NOAEL and the 
LOAEL from the toxicity studies are discussed in ``Aluminum Sulfate: 
Human Health Risk Assessment and Ecological Effects Assessment for 
Proposed Exemption from the Requirement for a Tolerance When Used as an 
Inert Ingredient in Antimicrobial Pesticide Formulations Applied to 
Food-Contact Surfaces'' in docket ID number EPA-HQ-OPP-2012-0267.

A. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological 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

[[Page 32036]]

for derivation of reference values for risk assessment. PODs are 
developed based on a careful analysis of the doses in each 
toxicological study to determine the dose at which the NOAEL and the 
LOAEL are identified. 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 RfD--and a safe 
margin of exposure (MOE). For non-threshold 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/pesticides/factsheets/riskassess.htm.
    A summary of the toxicological endpoints for aluminum sulfate used 
for human risk assessment is discussed below:
    Acute Dietary Endpoint. No appropriate endpoint was identified from 
any of the aluminum sulfate studies in the database, including 
developmental toxicity studies in the rat. Consequently, EPA determined 
that there was no basis for selecting a dose and endpoint for an acute 
POD for the general population or females 13-49 years old.
    Chronic Dietary Endpoint. A 2-generation reproduction study of 
aluminum sulfate in rats was considered critical in establishing the 
POD for chronic dietary risk assessment. The study supports a NOAEL of 
41 mg/kg/day and a LOAEL of 188 mg/kg/day for decreased body weight in 
parents and pups and a delay in vaginal opening and should be used as 
the POD for all durations and exposure scenarios. An uncertainty factor 
(UF) of 100X (10X for interspecies extrapolation and 10X for 
intraspecies variation) is applied to obtain a chronic reference dose 
(cRfD) of 0.41 mg/kg/day. The Food Quality Protection Act (FQPA) factor 
is reduced to 1X. The chronic population adjusted dose (cPAD) is 0.41 
mg/kg/day. This cPAD is protective of potential neurotoxicological 
effects of aluminum compounds.

B. Exposure Assessment

    1. Dietary exposure from food and feed uses. Exposures to aluminum 
sulfate can occur following ingestion of foods with residues from food-
contact surface sanitizing solutions for public eating places, treated 
dairy- and food-processing equipment and utensils as well as pre-
harvest crop uses. In evaluating dietary exposure to aluminum sulfate, 
EPA considered exposure under the requested exemption from the 
requirement of a tolerance as well as exposures from existing uses of 
aluminum sulfate under the extant exemption from the requirement of a 
tolerance under 40 CFR 180.920. EPA assessed dietary exposures from 
aluminum sulfate in food as follows:
    i. Acute exposure. Quantitative acute dietary exposure and risk 
assessments are performed for a food-use pesticide chemical, if a 
toxicological study has indicated the possibility of an effect of 
concern occurring as a result of a 1-day or single exposure. No such 
effects were identified in the toxicological studies for aluminum 
sulfate; therefore, a quantitative acute dietary exposure assessment is 
unnecessary.
    ii. Chronic exposure. The chronic dietary exposure assessment for 
this inert ingredient utilizes the Dietary Exposure Evaluation Model 
Food Commodity Intake Database (DEEM-FCID), Version 3.16, EPA, which 
includes food consumption information from the U.S. Department of 
Agriculture's National Health and Nutrition Examination Survey, ``What 
We Eat In America'', (NHANES/WWEIA). This dietary survey was conducted 
from 2003 to 2008. In the absence of actual residue data, the inert 
ingredient evaluation is based on a highly conservative model that 
assumes that the residue level of the inert ingredient would be no 
higher than the highest established tolerance for an active ingredient 
on a given commodity. Implicit in this assumption is that there would 
be similar rates of degradation between the active and inert ingredient 
(if any) and that the concentration of inert ingredient in the 
scenarios leading to these highest of tolerances would be no higher 
than the concentration of the active ingredient. The model assumes 100 
percent crop treated (PCT) for all crops and that every food eaten by a 
person each day has tolerance-level residues. A complete description of 
the general approach taken to assess inert ingredient risks in the 
absence of residue data is contained in the memorandum entitled ``Alkyl 
Amines Polyalkoxylates (Cluster 4): Acute and Chronic Aggregate (Food 
and Drinking Water) Dietary Exposure and Risk Assessments for the 
Inerts'' (D361707, S. Piper, 2/25/09) and can be found at https://www.regulations.gov in docket ID number EPA-HQ-OPP-2008-0738.
    Additionally, a dietary exposure assessment of aluminum sulfate 
resulting from the requested use in antimicrobial food-contact surface 
sanitizing solutions was conservatively assumed that 100% of the diet 
results from food treated with food-contact surface sanitizers and that 
100% of the sanitizing solution is transferred into food. A highly 
conservative model based on FDA assumptions regarding transfer of food 
contact sanitizing solution residues to food is utilized.
    The dietary exposure values derived from both the conservative 
model used to estimate residues from application to growing crops are 
combined with the exposures estimated from the antimicrobial food-
contact sanitizer uses.
    iii Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that aluminum sulfate is not expected to pose a cancer risk 
to humans. Therefore, a dietary exposure assessment for the purpose of 
assessing cancer risk is unnecessary.
    2. Dietary exposure from drinking water. For the purpose of the 
screening level dietary risk assessment to support this request for an 
exemption from the requirement of a tolerance for aluminum sulfate, a 
conservative drinking water concentration value of 100 parts per 
billion (ppb) based on screening level modeling was used to assess the 
contribution to drinking water for the chronic dietary risk assessment 
of aluminum sulfate. This value was directly entered into the dietary 
exposure model.
    3. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., textiles (clothing and diapers), carpets, swimming 
pools, and hard surface disinfection on walls, floors, tables).
    There are no registered pesticide products containing aluminum 
sulfate as an inert ingredient for any specific use patterns that would 
result in residential exposure.
    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 aluminum sulfate to share a common mechanism of 
toxicity with any other substances, and aluminum sulfate does not 
appear to produce a toxic metabolite produced by other substances. For 
the purposes of this tolerance action, therefore, EPA has assumed that 
aluminum sulfate does not

[[Page 32037]]

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 https://www.epa.gov/pesticides/cumulative.

C. 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 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.
    2. Prenatal and postnatal sensitivity. In a 2-generation 
reproduction toxicity study, there was no evidence of increased 
susceptibility of infants and children to aluminum sulfate. In this 
study, the offspring and parental toxicity NOAEL was 41 mg/kg/day based 
on decreased weight gain in offspring, decreased body weight in 
parental animals, and a delay in vaginal opening seen at the LOAEL of 
188 mg/kg/day.
    3. Conclusion. EPA has determined that reliable data show the 
safety of infants and children would be adequately protected if the 
FQPA SF were reduced to 1X. That decision is based on the following 
findings:
    i. The toxicity database for aluminum sulfate includes a 2-
generation reproduction study, as well as chronic/carcinogenicity 
studies, mutagenicity studies, neurotoxicity studies and developmental 
neurotoxicity studies on other related aluminum compounds. The Agency 
concludes that for this ingredient, the results of these studies 
provide a reliable basis for assessing the range of potential effects 
to infants and children, such that the Agency has determined that no 
additional data are necessary at this time to evaluate effects to 
infants and children.
    ii. There are available data on neurotoxicity and developmental 
neurotoxicity on aluminum compounds. The point of departure selected 
for risk assessment is based on a 2-generation rat reproductive 
toxicity study with aluminum sulfate, in which adverse effects were 
identified at dose levels below the dose levels at which neurotoxic 
effects or developmental neurotoxicological effects were observed and 
is therefore protective of those effects; no additional UFs are 
required to account for neurotoxicity.
    iii. There is no evidence of increased susceptibility due to pre-or 
post-natal exposure to aluminum in infants and children.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and residues equivalent to the highest established 
tolerance-level residues for every food commodity. EPA made 
conservative (protective) assumptions utilizing a 100 ppb default value 
in the ground and surface water modeling used to assess exposure to 
aluminum sulfate in drinking water. In addition, highly conservative 
assumptions were utilized in assessing exposures to aluminum sulfate 
resulting from the proposed use in food-contact surface antimicrobial 
pesticide formulations. These assessments will not underestimate the 
exposure and risks posed by aluminum sulfate.

D. 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 PAD (aPAD) and cPAD. For linear cancer risks, EPA calculates the 
lifetime probability of acquiring cancer given the estimated aggregate 
exposure. Short-, intermediate-, and chronic-term risks are evaluated 
by comparing the estimated aggregate food, water, and residential 
exposure to the appropriate PODs to ensure that an adequate MOE exists.
    1. Acute risk. An acute aggregate risk assessment takes into 
account acute exposure estimates from dietary consumption of food and 
drinking water. No adverse effect resulting from a single oral exposure 
was identified, therefore, an acute dietary exposure assessment was not 
conducted.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
aluminum sulfate from food and water will utilize 6.7% of the cPAD for 
children 1-2 years old, the population group receiving the greatest 
exposure.
    3. Short-term and intermediate-term risk. Short-term and 
intermediate-term aggregate exposure takes into account short-term 
residential exposure plus chronic exposure to food and water 
(considered to be a background exposure level). A short-term/
intermediate-term adverse effect was identified; however, aluminum 
sulfate is not used as inert ingredient in any pesticide product 
registered for any use patterns that would result in short-term or 
intermediate-term residential exposure. Because there is no short-term 
or intermediate-term residential exposure and chronic dietary exposure 
has already been assessed under the appropriately protective cPAD 
(which is at least as protective as the POD used to assess short-term 
risk), no further assessment of short-term risk is necessary, and EPA 
relies on the chronic dietary risk assessment for evaluating short-term 
risk for aluminum sulfate.
    4. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in a rodent carcinogenicity study with 
aluminum potassium sulfate, aluminum sulfate is not expected to pose a 
cancer risk to humans.
    5. Determination of safety. Based on these risk assessments, 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 aluminum sulfate residues.

VII. Other Considerations

A. 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 without any numerical limitation. EPA is establishing a 
limitation on the amount of aluminum sulfate that may be used in food-
contact surface antimicrobial applications. That 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 food-contact surface antimicrobial 
applications for sale or distribution that contains greater than 50 ppm 
of aluminum sulfate by weight.

VIII. Conclusion

    Therefore, an exemption is established for residues of aluminum 
sulfate for use as an inert ingredient in antimicrobial pesticide 
formulations applied to food-contact surfaces in public eating places, 
dairy-processing equipment, and food-processing equipment and utensils 
at a maximum end use concentration not to exceed 50 ppm.

[[Page 32038]]

IX. Statutory and Executive Order Reviews

    This action establishes an exemption from the requirement of 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 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).

X. 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).
