### 7266 Federal Register / Vol. 78, No. 22 / Friday, February 1, 2013 / Rules and Regulations

2004, the Coast Guard established regulations for the security of Department of Defense assets and military cargo in the navigable waters of Puget Sound to and adjacent waters. (See 69 FR 52600, Aug. 27, 2004). When subject to enforcement, this regulation prohibits persons and vessels from the immediate vicinity of these facilities during military cargo loading and unloading operations. The security zone will also provide for the regulation of vessel traffic in the vicinity of military cargo loading facilities in the navigable waters of the United States. In addition, the regulation establishes requirements for all vessels to obtain permission of the COTP or Designated Representative, including the Vessel Traffic Service (VTS), to enter, move within, or exit these security zones when they are enforced. Entry into this zone is prohibited unless otherwise exempted
or excluded under 33 CFR 165.1321 or unless authorized by the Captain of the Port or Designated Representative.

This notice is issued under authority of 33 CFR 165.1321 and 5 U.S.C. 552 (a).
In addition to this notice in the Federal Register , the Coast Guard will provide the maritime community with notification of this enforcement period
via marine information broadcasts and
on-scene assets. If the COTP determines that the regulated area need not be
enforced for the full duration stated in this notice, a Broadcast Notice to Mariners may be used to grant general permission to enter the regulated area.

Dated: January 23, 2013.

S.J. Ferguson, Captain, U.S. Coast Guard, Captain of the Port, Puget Sound.

II. Summary of Petition-For Tolerance

In the Federal Register of May 19, 2010 (75 FR 28009) (FRL–8823–2), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 0F7690) by BASF Corporation, 26 Davis Drive, P.O. Box 13528, Research Triangle Park, NC 27709–3528. The petition requested that 40 CFR 180.418 be amended by


### 7267 Federal Register / Vol. 78, No. 22 / Friday, February 1, 2013 / Rules and Regulations

establishing tolerances for residues of the insecticide alpha-cypermethrin in or on tree nuts, Group 14; dried shelled pea and bean, except soybean, subgroup 6C; corn, grain; pop corn; sweet corn; soybeans; and sugar beet, roots at 0.05 parts per million (ppm); succulent shelled pea and bean, subgroup 6B; and root and tuber vegetables, Group 1 at 0.1 ppm; cucurbit vegetables, Group 9; fruiting vegetables, Group 8; sugar beet, tops; and wheat, grain at 0.2 ppm; citrus fruit, Group 10 at 0.35 ppm; cottonseed; edible podded legume vegetable, subgroup 6A; and sorghum, grain at 0.5 ppm; and rice, grain at 1.5 ppm; citrus, dried pulp at 1.8 ppm; head and stem
Brassica, subgroup 5A at 2.0 ppm; citrus, oil at 4.0 ppm; leafy vegetable,
except Brassica, Group 4 at 10 ppm; and alfalfa, hay at 15 ppm. There were no comments received in response to the notice of filing.

Based upon review of the data supporting the petition, EPA hasestablished tolerances for alphacypermethrin ((R)-cyano(3- phenoxyphenyl)methyl (1 S, 3 S)-rel-3- (2,2-dichloroethenyl)-2,2- dimethylcyclopropane carboxylate) as explained in Unit IV.D.

III. Aggregate Risk Assessment and Determination of Safety

Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’ Section 408(b)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is
reliable information.’’ This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section 408(b)(2)(C) of FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a
tolerance and to ‘‘ensure that there is a reasonable certainty that no harm will
result to infants and children from aggregate exposure to the pesticide
chemical residue. * * *’’

Consistent with FFDCA section 408(b)(2)(D), and the factors specified in FFDCA section 408(b)(2)(D), EPA has
reviewed the available scientific data
and other relevant information in support of this action. EPA has
sufficient data to assess the hazards of
and to make a determination onaggregate exposure for alphacypermethrin including exposure resulting from the tolerances established by this action. EPA’s assessment of exposures and risks associated with alpha-cypermethrin follows.

A. Toxicological Profile

EPA has evaluated the available toxicity data and considered its validity, completeness, and reliability as well as the relationship of the results of the
studies to human risk. EPA has also
considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including
infants and children.

Alpha-cypermethrin, cypermethrin, and zeta-cypermethrin are all pyrethroid
insecticides and are isomer mixtures of the same chemical. The cypermethrins have been evaluated for a variety of toxic effects in experimental toxicity studies. Behavioral changes commonly seen with type II pyrethroids were consistently noted in the toxicology database for the cypermethrins. These behavioral changes included tremors, gait abnormalities, limb conditions, ataxia and hypersensitivity. Additionally, body weight changes were routinely observed and mortality was seen in a few studies in rats and dogs. Clinical signs were also noted in all acute neurotoxicity studies. Decreased activity, gait abnormalities, tremors, limb conditions, and hypersensitivity were observed at the mid and high doses. Additionally, slight nerve degeneration was seen in the acuteneurotoxicity study with alphacypermethrin at the high dose. In the subchronic neurotoxicity studies with cypermethrin and zeta-cypermethrin,
similar behavioral effects were seen along with decreased food consumption, body weight, and body weight gain.

Acute toxicology studies conducted with cypermethrins indicate moderate acute toxicity via the oral route and low toxicity via the acute dermal or inhalation routes. Additionally, mild irritation was seen in primary eye and
skin irritation studies but no dermal
sensitization was observed.

Dermal toxicity studies are available for zeta-cypermethrin (rat) and cypermethrin (rabbit), in which local
irritation was observed in rats and rabbits at the highest doses tested. No systemic effects were observed in the 21-day dermal study in the rat conducted with zeta-cypermethrin at dose levels up to 1,000 milligrams/ kilogram/day (mg/kg/day). In the dermal toxicity study in rabbits with cypermethrin, systemic effects were observed (focal necrosis of the liver, decreased testicular weights, and decreased body weight in females). However, these observations in the
rabbit were not used for risk assessment because the testing method (i.e., abraded skin) does not simulate actual exposure and results in compromised test conditions. Additionally, there would be physiological differences between abraded and non-abraded animals, further undermining the relevance of
these results for risk assessment.

Developmental toxicity and reproduction studies are available for the cypermethrins. In the developmental toxicity studies in ratswith cypermethrin and zetacypermethrin, there was no evidence of developmental toxicity up to the highest doses tested. Maternal toxicity included decreased body weight gain and food consumption in both chemicals. Splayed limbs, spasms and hypersensitivity to noise and
convulsions were seen with cypermethrin, and ataxia, urine-stained abdominal fur, and fecal-stained fur were seen with zeta-cypermethrin. In the developmental toxicity study in rats with alpha-cypermethrin, offspring
effects were limited to decreased fetal body weight. Maternal effects observations in the study were unsteady gait, piloerection, limb splay, and hypersensitivity to sound and touch at the same dose. In the developmental toxicity studies in rabbits with the cypermethrins, there was no evidence of developmental toxicity up to the highest
dose tested. Maternal effects seen with cypermethrin included decreased body weight gain, anorexia, abdomino-genital staining, decreased feces, and red orpink material in the pan. With alphacypermethrin, maternal effects were body weight loss and decreased food consumption. Multi-generation reproduction studies in rats areavailable for cypermethrin and zetacypermethrin. In the reproduction study with cypermethrin, decreased body weight gain was observed in adult animals and decreased body weight gain was seen in offspring animals at the highest dose tested. In the reproduction study using zeta-cypermethrin, decreased body weight gain and mortality were observed in offspring animals in the presence of mortality, increased brain weights, decreased body weights, and neurotoxicity in maternal
animals.

No effects were observed in an immunotoxicity study in rats with alpha-cypermethrin up to the limit dose.

Alpha-cypermethrin is classified as a Group C ‘‘Possible human carcinogen,’’ based on an increased incidence of lung adenomas and adenomas plus
carcinomas combined in females in a mouse carcinogenicity study. The


### 7268 Federal Register / Vol. 78, No. 22 / Friday, February 1, 2013 / Rules and Regulations

presence of common benign tumors (lung adenomas), in one species (mice) and one sex (female), with no increase in the proportion of malignant tumors or
decrease in the time-to-tumor occurrence, together with the lack of mutagenic activity, was not considered strong enough to warrant a quantitative
estimation of human risk. Quantification of risk using a non-linearapproach (i.e., acute populationadjusted dose (aPAD), acute reference dose (aRfD)) adequately accounts for all chronic toxicity, including carcinogenicity that could result from exposure to alpha-cypermethrin. While the Agency would typically use a chronic population-adjusted dose (cPAD) to protect for cancer concerns, use of the aPAD is protective because increasing toxicity with increasing duration of exposure is not demonstrated for the cypermethrins.
The no-observed-adverse-effect-level (NOAEL) observed in the mouse cancer study in which tumors were observed is 14 mg/kg/day, 2-fold higher than the point of departure (POD) used for acute
risk assessment. The lowest-observedadverse-effect-level (LOAEL) in the mouse cancer study is 57 mg/kg/day based on liver effects, not tumor
formation. The tumors were seen at 229 mg/kg/day. The acute POD of 7.16 mg/ kg/day selected for risk assessment is
32-fold lower than the dose that induced lung tumors in mice. Only the mouse study with cypermethrin resulted in tumor formation, no evidence of carcinogenicity was
observed in cancer studies in rats withcypermethrin or mice with alphacypermethrin.

as the NOAEL and the LOAEL from the toxicity studies can be found at http:// www.regulations.gov in document

OPP–2012–0185–0005.

B. Toxicological Points of Departure and Levels of Concern

Once a pesticide’s toxicological profile is determined, EPA identifies toxicological POD and levels of concern (LOC) to use in evaluating the risk posed by human exposure to the pesticide. For hazards that have a threshold below which there is no appreciable risk, the toxicological POD
is used as the basis for derivation of
reference values for risk assessment. PODs are developed based on a careful analysis of the doses in each toxicological study to determine the
dose at which no adverse effects are
observed and the lowest dose at which
adverse effects of concern are identified. Uncertainty/safety factors are used in conjunction with the POD to calculate a safe exposure level—generally referred to as a PAD or a reference dose (RfD)— and a safe margin of exposure (MOE). For non-threshold risks, EPA 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 http:// www.epa.gov/pesticides/factsheets/
riskassess.htm.

C. Exposure Assessment

1. Dietary exposure from food and feed uses. In evaluating dietary exposure to alpha-cypermethrin, EPA considered exposure under the petitioned-for tolerances as well as allexisting cypermethrin and zetacypermethrin tolerances in 40 CFR 180.418. EPA assessed dietary exposures from alpha-cypermethrin in
food as follows:

i. Acute exposure. Quantitative acute dietary exposure and risk assessments are performed for a food-use pesticide, if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a 1-day or single exposure. Such effects were identified for alpha-cypermethrin.

In assessing aggregate risk to alphacypermethrin, EPA considered not only the exposure associated with theproposed food uses for alphacypermethrin, but also the potential dietary and drinking water contribution and residential exposure from existinguses of cypermethrin and zetacypermethrin. In estimating acute dietary exposure, EPA used food consumption information from the U.S. Department of Agriculture (USDA)
1994–1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII). As to residue levels in food, EPA used a partially refined (probabilistic) dietary exposure assessment to determine the exposure
and risk estimates which result from the use of cypermethrins on the crops listed under 40 CFR 180.418 and the proposed new uses. Anticipated residues from USDA Pesticide Data Program (PDP) monitoring data, field trial data, and empirical processing factors, and percent crop treated (PCT) estimates for
some commodities were used where appropriate.

ii. Chronic exposure. Based on the data summarized in Unit III.A., there is no increase in hazard from repeated exposures to alpha-cypermethrin; the acute dietary exposure assessment is higher than for chronic dietary exposures because the acute exposure levels are greater than the chronic exposure levels, therefore, a chronic dietary risk assessment was not
conducted.

iii. Cancer. As noted in Unit III.A., the Agency has determined that quantification of risk using a non-linear approach (i.e., aPAD) will adequately account for all chronic toxicity, including carcinogenicity, that couldresult from exposure to alphacypermethrin. Additionally, because an
assessment of cancer risk would estimate exposure based on average residue levels and the acute assessment used high-end residue levels, the acute dietary assessment will be protective of any cancer effects resulting from consumption of alpha-cypermethrin
residues in foods.

iv. Anticipated residue and PCT information. Section 408(b)(2)(E) of
FFDCA authorizes EPA to use available data and information on the anticipated residue levels of pesticide residues in food and the actual levels of pesticide
residues that have been measured in food. If EPA relies on such information, EPA must require pursuant to FFDCA section 408(f)(1) that data be provided 5 years after the tolerance is established, modified, or left in effect, demonstrating
that the levels in food are not above the levels anticipated. For the presentaction, EPA will issue such Data CallIns as are required by FFDCA section 408(b)(2)(E) and authorized under FFDCA section 408(f)(1). Data will be required to be submitted no later than 5 years from the date of issuance of these tolerances demonstrating that the
levels in food are not above the levels anticipated.

Section 408(b)(2)(F) of FFDCA states that the Agency may use data on the actual percent of food treated for assessing chronic dietary risk only if:

• Condition a: The data used are reliable and provide a valid basis to show what percentage of the food derived from such crop is likely to contain the pesticide residue.

• Condition b: The exposure estimate does not underestimate exposure for any significant subpopulation group.

• Condition c: Data are available on pesticide use and food consumption in a particular area, the exposure estimate does not understate exposure for the population in such area.


### 7270 Federal Register / Vol. 78, No. 22 / Friday, February 1, 2013 / Rules and Regulations

In addition, the Agency must provide for periodic evaluation of any estimates used. To provide for the periodic
evaluation of the estimate of PCT as required by FFDCA section 408(b)(2)(F), EPA may require registrants to submit data on PCT. The following maximum
PCT estimates were used in the acute dietary risk assessment, which was relied on in assessing chronic risk, for the following crops that are currently registered for the cypermethrins: Almonds, 2.5%; apples, 2.5%; broccoli, 30%; cabbage, 30%; carrot, 10%; cauliflower, 25%; celery, 60%; cherries, 5%; grapefruit, 50%; green beans, 20%; green peas, 15%; lemon, 2.5%; lettuce, 65%; orange, 45%; peach, 5%; peppers, 30%; potato, 5%; sweet corn, 20%; spinach, 45%; tomato, 10%; and watermelon, 10%.

The following average PCT estimates were used to calculate average dietary exposures in order to assess short-term aggregate risk to the cypermethrins: Almonds, 1%; apples, 1%; broccoli, 20%; cabbage, 15%; carrot, 2.5%; cauliflower, 15%; celery, 35%; cherries, 5%; grapefruit, 35%; green beans, 15%; green peas, 10%; lemon, 1%; lettuce, 55%; orange, 35%; peach, 2.5%; peppers, 15%; potato, 1%; sweet corn, 15%; spinach, 30%; tomato, 5%; andwatermelon, 2.5%. The zetacypermethrin PCT data was used as asurrogate for future PCT of alphacypermethrin.

In most cases, EPA uses available data from the U.S. Department of Agriculture/National Agricultural Statistics Service (USDA/NASS), proprietary market surveys, and the
National Pesticide Use Database for the chemical/crop combination for the most recent 6–7 years. EPA uses an average PCT for chronic dietary risk analysis. The average PCT figure for each existing use is derived by combining available public and private market survey data for that use, averaging across all observations, and rounding to the nearest 5%, except for those situations in which the average PCT is less than 1. In those cases, 1% is used as the average PCT and 2.5% is used as the maximum
PCT. EPA uses a maximum PCT for acute dietary risk analysis. The maximum PCT figure is the highest observed maximum value reported within the recent 6 years of available public and private market survey data for the existing use and rounded up to the nearest multiple of 5%.

The Agency believes that the three
conditions discussed in Unit III.C.1.iv. have been met. With respect to Condition a, PCT estimates are derived from Federal and private market survey data, which are reliable and have a valid basis. The Agency is reasonably certain that the percentage of the food treated is not likely to be an underestimation. As to Conditions b and c, regional consumption information and consumption information for significant subpopulations is taken into account through EPA’s computer-based model for evaluating the exposure of significant subpopulations including several regional groups. Use of this consumption information in EPA’s risk assessment process ensures that EPA’s exposure estimate does not understate exposure for any significant subpopulation group and allows the Agency to be reasonably certain that no regional population is exposed to residue levels higher than those estimated by the Agency. Other than the data available through national food consumption surveys, EPA does not
have available reliable information on the regional consumption of food to which alpha-cypermethrin may be applied in a particular area.

2. Dietary exposure from drinking

water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for alpha-cypermethrin in drinking
water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of alpha-cypermethrin. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www.epa.gov/oppefed1/models/
water/index.htm.

Based on the First Index Reservoir Screening Tool (FIRST) and Screening Concentration in Ground Water (SCI– GROW) models the estimated drinkingwater concentrations (EDWCs) of alphacypermethrin were 3.77 parts per billion (ppb) for surface water and 0.0036 ppb for ground water. In the dietary risk assessment conducted to support the proposed uses, EPA incorporated the surface water EDWCs directly into the dietary model, since surface water estimates were higher than those provided for ground water.

3. From non-dietary exposure. The term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, andflea and tick control on pets). Alphacypermethrin is not registered for any specific use patterns that would result in residential exposure. There are no proposed residential uses associated with alpha-cypermethrin; however, there are registered residential uses for cypermethrin and zeta-cypermethrin
that have been reassessed to reflect updates to the Agency’s 2012 Residential standard operating procedures (SOPs) along with policy changes for body weight assumptions
and inhalation rates. These revised residential exposures have been incorporated into the human healthaggregate risk assessment for alphacypermethrin, which must consider all potential exposures to the cypermethrins. The Agency has determined that short-term exposures are likely to occur in a residential setting for the cypermethrins; however, they do not increase in potency with repeated dosing. EPA assessed residential exposure using the following assumptions. The quantitative exposure/risk assessment developed for
residential handlers is based on the following scenarios:

• Mixer/loader/applicator using hoseend sprayer on turf;

• Mixer/loader/applicator using backpack on turf and gardens;

• Mixer/loader/applicator using manually pressurized handwand for indoor surfaces;

• Application via aerosol can for indoor surfaces and space.

Since a dermal endpoint was not identified, only a quantitative inhalation handler exposure assessment was performed. Residential handler inhalation exposure estimates were calculated based on a human equivalent concentration and human equivalent dose which reflect 24 hours of exposure. Since handler exposure is expected to be significantly less than 24 hours, the inhalation exposure estimates are sufficiently protective of all scenarios (turf, gardens, and indoor surface space). Although there is potential inhalation exposure resulting from the application of dog tags and spot-on products for pets, inhalation exposure is considered negligible for these scenarios and therefore a quantitative assessment was not performed for these uses.

There is the potential for postapplication exposure for individuals as a result of being in an environment that has been previously treated with cypermethrin or zeta-cypermethrin. However, the combination of low vapor pressure for chemicals typically used as active ingredients in outdoor residential pesticide products and dilution in outdoor air is likely to result in minimal inhalation exposure. Therefore, a quantitative post-application inhalation exposure assessment for cypermethrin
turf uses was not conducted. Since a dermal endpoint was not identified, and indoor post-application inhalation exposure resulting from aerosol space sprays, foggers, and pet (i.e., dog tag, spot-on) uses is negligible, the only


### 7271 Federal Register / Vol. 78, No. 22 / Friday, February 1, 2013 / Rules and Regulations

potential post-application exposure pathways of concern are incidental oral for children, and post-application inhalation exposure for adults and children resulting from indoor crack and crevice applications made with a manually pressurized handwand. The quantitative exposure/risk assessment for residential post-application exposures is based on the following

scenarios:

• Incidental oral (hand-to-mouth, object-to-mouth, and soil ingestion) exposure from turf for children.

• Incidental oral (hand-to-mouth and object-to-mouth) exposure from indoor foggers for children.

• Incidental oral (hand-to-mouth and object-to-mouth) exposure from pets for
children.

• Inhalation exposure for adults and children resulting from crack and crevice application to an indoor surface.

• Incidental oral (hand-to-mouth and object-to-mouth) exposure for children from indoor surface applications.

Risk estimates resulting from different exposure routes may be combined when it is likely that they can occur simultaneously based on the use pattern and when the toxicological effects across different routes of exposure are the same. Although, in the case of children, inhalation and incidental oral exposure routes share a common toxicological endpoint, risk estimates
were not combined for those routes forturf, indoor fogger, and pet since postapplication inhalation exposure is considered negligible. However, inhalation and incidental oral exposures were combined for post-application risk
assessment associated with the indoor
crack and crevice use. Inhalation and
incidental oral routes have different LOCs. Therefore, in order to combine exposure from the various routes, the aggregate risk index (ARI) approach is used to estimate exposure and risk. When this approach is used, aggregate risks are not of concern provided the calculated ARI is greater than 1.

The incidental oral scenarios from indoor exposure following crack and crevice applications and outdoor exposure from turf were not combined, not only because they are not likely to co-occur, but also because combiningthese scenarios would be overlyconservative due to the conservative
nature of each of the individual

assessments.

found at http://www.epa.gov/pesticides/ trac/science/trac6a05.pdf.

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.’’

The Agency is required to consider
the cumulative risks of chemicals sharing a common mechanism of toxicity. The Agency has determined that the pyrethroids and pyrethrins, including the cypermethrins, share a common mechanism of toxicity. The members of this group share the ability to interact with voltage-gated sodium channels, ultimately leading to neurotoxicity. The cumulative risk assessment for the pyrethroids and pyrethrins was published in the Federal Register on November 9, 2011 (76 FR 69726) (FRL–8888–9), and is available at http://www.regulations.gov in the public docket, EPA–HQ–OPP–2011–0746.
Further information about the determination that pyrethroids and pyrethrins share a common mechanism of toxicity may be found in document ID: EPA–HQ–OPP–2008–0489–0006.

The cypermethrins were included in
a recent cumulative risk assessment for pyrethrins and pyrethroids. Theproposed new uses of alphacypermethrin will not significantly impact the cumulative assessment because, in the cumulative assessment, residential exposure was the greatest contributor to the total exposure. There
are no new residential uses for the cypermethrins, and the proposed new uses will have no impact on the residential component of the cumulative
risk estimates.

Dietary exposures make a minor contribution to total pyrethroid exposure. The dietary exposure assessment performed in support of the pyrethroid cumulative was much more highly refined than that performed for the single chemical. The dietary exposure assessment for the single
chemical included conservative assumptions, using field trial data for many commodities, including the proposed new uses, with the assumption of 100 PCT, and the most sensitive apical endpoint in the cypermethrins hazard database was
selected to derive the POD. Additionally, the POD selected for alpha-cypermethrin is specific to the cypermethrins, whereas the POD
selected for the cumulative assessment
was based on-common-mechanism-ofaction data that are appropriate for all 20 pyrethroids included in the
cumulative assessment. For information regarding EPA’s efforts to evaluate the risk of exposure to pyrethroids, refer to http:// www.epa.gov/oppsrrd1/reevaluation/ pyrethroids-pyrethrins.html.

D. Safety Factor for Infants and
Children

1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an additional tenfold (10X) margin of safety for infants and children in the
case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines
based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the Food Quality Protection Act (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.

2. Prenatal and postnatal sensitivity. In guideline developmental and reproduction studies with the cypermethrins, there was no evidence of increased qualitative or quantitative susceptibility in rats or rabbits.

In a guideline developmentalneurotoxicity (DNT) study with zetacypermethrin, there was increased sensitivity in the offspring based on body weight changes in pups (5%–10%)
in the absence of treatment-related effects in maternal animals. Although, there was a 5%–8% decrease in maternal body weight in this study, a body weight decrease of <10% is generally not considered adverse in adults, as this is considered to be within the range of variability because the magnitude of body weight per se is typically small (as an example, a 3 gram (g) decrease in body weight from a 338 g rat), and adults are no longer in the growth/development phase. In contrast, the offspring are at a stage of growth and development and are therefore expected to be gaining rather than losing weight. Thus, a smaller percent decrease in body weight is considered adverse in the young relative to adults. In the case of zeta-cypermethrin, the decrease in body weight of the young is comparable to adults; however, it was considered adverse in the young but not in the adults. This disparity in interpretation leads to an apparent increase in sensitivity in the young; however, concern is reduced since the magnitude of body weight decrements was similar in adult and young animals. The results from the DNT study are very similar to results observed in the reproduction


### 7272 Federal Register / Vol. 78, No. 22 / Friday, February 1, 2013 / Rules and Regulations

studies where body weight (bwt) changes (decreased body weight gain) were seen in maternal and offspring
animals at doses similar to those in the DNT study, with no indication of increased susceptibility. Therefore,
there is no residual concern for effects observed in the study. Additionally,
there are well-characterized dose responses, with clear NOAELs and
LOAELs for effects seen in the DNT and reproduction studies, and the endpoints
and PODs selected for risk assessment are protective.

High-dose LD 50 studies (studies assessing what dose results in lethality to 50% of the tested population) in the
scientific literature indicate that pyrethroids can result in increased quantitative sensitivity in the young, typically in the form of neurotoxicity. Examination of pharmacokinetic and pharmacodynamic data indicates that the sensitivity observed at high doses is related to pyrethroid age-dependent pharmacokinetics—the activity of enzymes associated with the metabolism of pyrethroids. With otherwise equivalent administered doses for adults and juveniles, predictive pharmacokinetic models
indicate that the differential adultjuvenile pharmacokinetics will result in a 3X greater dose at the target organ in juveniles compared to adults. No evidence of increased quantitative or qualitative susceptibility was seen in the pyrethroid scientific literature related to pharmacodynamics (the effect of pyrethroids at the target tissue) both with regard to inter-species differences
between rats and humans and to differences between juveniles and adults. Specifically, there are in vitro pharmacodynamic data and in vivo data indicating similar responses between adult and juvenile rats at low doses and data indicating that the rat is a conservative model compared to the human based on species-specific pharmacodynamics of homologous
sodium channel isoforms in rats and
humans.

3. Conclusion. The FQPA SF was reduced to 1X for the general population, women of child bearing age and children > 6 years. For exposures from birth to <6 years of age, a 3X FQPA SF was retained based on the following
considerations:

i. The toxicology database for the cypermethrins is not complete. While
the database is considered to be complete with respect to the guideline toxicity studies for alpha-cypermethrin, EPA lacks additional data to fully characterize the potential for juvenile sensitivity to neurotoxic effects of pyrethroids. In light of the literature studies indicating a possibility of increased sensitivity to cypermethrins in juvenile rats at high doses, EPA has requested proposals for study protocols which could identify and quantify potential juvenile sensitivity. However, when evaluated together, the toxicity studies for the cypermethrins can be
used to characterize toxic effects including potential developmental and reproductive toxicity, immunotoxicity, and neurotoxicity. Acceptable developmental toxicity studies in rats and rabbits, reproduction studies in rats, neurotoxicity studies (acute neurotoxicity (ACN), subchronic neurotoxicity (SCN), and DNT) in rats, and immunotoxicity studies in rats are available. In addition, route-specific
dermal and inhalation studies are
available.

ii. After reviewing the extensive body of data and peer-reviewed literature on pyrethroids, the Agency has reached a number of conclusions regarding fetal juvenile sensitivity for pyrethroids, including the following:

• Based on an evaluation of over 70 guideline toxicity studies for 24 pyrethroids submitted to the Agency, including prenatal developmental toxicity studies in rats and rabbits, and prenatal and postnatal multi-generation reproduction toxicity studies and DNTs in rats in support of pyrethroid registrations, there is no evidence that pyrethroids directly impact developing fetuses. None of the studies show any indications of fetal toxicity at doses that do not cause maternal toxicity.

• Increased susceptibility was seen in offspring animals in the DNT study with zeta-cypermethrin (decreased pup body weights) and DNT and reproduction studies with beta-cyfluthrin (decreased body weights and tremors). However, the reductions in body weight and the other non-specific effects occur at higher doses than neurotoxicity, the effect of concern for pyrethroids. The available developmental and reproduction guideline studies in rats with zeta-cypermethrin did not show increased sensitivity in the young to neurotoxic effects. Overall, findings of increased sensitivity in juvenile animals in pyrethroid studies are rare. Therefore, the residual concern for the postnatal
effects is reduced.

• High-dose LD 50 studies (studies assessing what dose results in lethality to 50% of the tested population) in the
scientific literature indicate that pyrethroids can result in increased quantitative sensitivity to juvenile
animals. Examination of pharmacokinetic and pharmacodynamic data indicates that the sensitivity observed at high doses is related to pyrethroid age-dependent pharmacokinetics—the activity of enzymes associated with the metabolism of pyrethroids. Furthermore, a rat PBPK model predicts a three-fold increase of pyrethroid concentration in juvenile brain compared to adults at high doses.

• In vitro pharmacodynamic data and

in vivo data indicate that adult and juvenile rats have similar responses to pyrethroids at low doses and therefore juvenile sensitivity is not expected at relevant environmental exposures. Further, data also show that the rat is a conservative model compared to the human based on species-specific pharmacodynamics of homologous
sodium channel isoforms.

iii. There are no residual uncertainties with regard to dietary and residential exposure. The dietary exposure assessments are based on high-end health protective residue levels (that account for parent and metabolites of concern), processing factors, and PCT assumptions. Furthermore, conservative, upper-bound assumptions were used to determine exposure through drinking water and residential sources, such that these exposures have
not been underestimated.

Taking all of this information into account, EPA has reduced the FQPA SF for women of child-bearing age and children over 6 years to 1X since after evaluation of over 70 guideline toxicity studies submitted to the Agency, including prenatal developmental toxicity studies in rats and rabbits, and multi-generation reproduction toxicity studies and DNTs in rats, there is no evidence that pyrethroids directly impact developing fetuses. Additionally, none of the studies show any indications of fetal/offspring toxicity at doses that do not cause maternal toxicity. However, since there remains some uncertainty as to juvenile sensitivity due to the findings in the high-dose LD 50 studies, EPA is retaining a FQPA SF for infants and children less than 6 years of age. This age group is a close approximation to the most sensitive human population, children from birth to <6 years old. EPA is seeking additional data to further characterize the potential neurotoxic risk pyrethroid toxicity. However, EPA has reliable data that show that reducing the FQPA SF to 3X will protect the safety of infants and children. These
data include:

(a) data from guideline studies with zeta-cypermethrin at relatively high doses that show no sensitivity with regard to neurotoxic effects (the most sensitive effect for the pyrethroids) and no residual concern regarding overall


### 7273 Federal Register / Vol. 78, No. 22 / Friday, February 1, 2013 / Rules and Regulations

juvenile sensitivity (i.e., sensitivity seen in body weight changes occurred at
doses above the level chosen for the POD);

(b) data showing that the potential sensitivity at high doses is due to pharmacokinetics alone;

(c) a rat PBPK model predicting a three-fold increase of pyrethroid concentration in juvenile brain compared to adults at high doses due to age-dependent pharmacokinetics; and

(d) data indicating that the rat is a conservative model compared to the human based on species-specific pharmacodynamics of homologous
sodium channel isoforms.

For several reasons, EPA concludes
these data show that a 3X factor is protective of the safety of infants and children. First, it is likely that theextensive guideline studies with zetacypermethrin showing no neurotoxicity sensitivity between adults and juveniles better characterize the potential sensitivity of juvenile animals than the

LD 50 studies. The high doses that produced juvenile sensitivity in the
literature studies are well above normal dietary or residential exposure levels of pyrethroids to juveniles and lower levels of exposure anticipated from dietary and residential uses are not expected to overwhelm the juvenile’s ability to metabolize pyrethroids, as occurred with the high doses used in
the literature studies. The lack of increased neurotoxic sensitivity of the young in the overwhelming majority (69 of 70) of the prenatal and postnatal guideline studies for pyrethroids supports this conclusion, despite the relatively high doses used in those studies. Second, limited in vitro and in

vivo data indicate similar pharmacodynamic response to pyrethroids between juvenile and adult rats. The portion of the uncertainty factor that accounts for potential pharmacodynamic differences betweenanimals and humans (i.e., the interspecies extrapolation factor) is likely to overstate the risk of the cypermethrins given the data showing similarities in pharmacodynamics between animals and humans. For the inter-species factor, the pharmacodynamic portion of the factor is generally considered to be 3X. However, for pyrethroids the actual difference is likely to be lower than 3X. In addition, there are data that show that there are no lifestage pharmacodynamic differences between young and adult rats. Standard uncertainty factors, such as those used in the cypermethrin risk assessment,
assume that there will be such differences. Finally, as indicated, pharmacokinetic modeling only predicts a 3X difference between juveniles and adults. Thus, even if there is increased juvenile neurotoxic sensitivity and even if the existing interspecies and intraspecies factors do not provide extra protection due to the conservative nature of their pharmacodynamic components for pyrethroids, the 3X additional factor will protect the young. Therefore, the FQPA factor of 3X is protective of potential juvenile sensitivity.

E. Aggregate Risks and Determination of Safety

EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure
estimates to the 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. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietaryexposure from food and water to alphacypermethrin will occupy 87% of the aPAD for all infants (<1 year old) and children 1–2 years old, the population groups receiving the greatest exposure.
This assessment is considered to be conservative, because tolerance level
residues and distributions of field trial data (as opposed to monitoring data) were used for many commodities. Additionally, although upper-bound estimates were used for drinking water, drinking water is not considered to be a major source of dietary exposure for the cypermethrins.

2. Chronic risk. Separate chronic and cancer dietary risk assessments were not conducted for the cypermethrins. Because of the rapid reversibility of the most sensitive neurotoxicity endpoint used for quantifying risks, there is no increase in hazard with increasing dosing duration, and therefore the acute dietary endpoint is protective for chronic and cancer dietary exposures.

3. Short-term risk. Short-term aggregate exposure takes into account short-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level).

Cypermethrin and zeta-cypermethrin are currently registered for uses that
could result in short-term residential exposure, and the Agency has determined that it is appropriate to aggregate chronic exposure through food
and water with short-term residential exposures to the cypermethrins including alpha-cypermethrin.

For assessing short-term aggregate risk, the average dietary exposure estimate was used since it represents a background exposure level from food and drinking water that may co-occur with residential exposures. Dietary and oral (hand to mouth) risks for children, and dietary and inhalation risks for

adults were combined in this assessment, since the toxicological endpoints were the same. However, the level of concern (LOC) values were different (oral adults and children ≥ 6 years old = 100; children <6 years old = 300), while inhalation LOC = 30. Therefore, the respective risk estimates are combined using the aggregate risk index (ARI) approach. When this approach is used, aggregate risks are not of concern provided the calculated ARI is greater than 1. The ARI for adults was

calculated to be 56 and the ARI for

children was 2.3. Because these ARIs are greater than 1, the risk estimates are

not of concern.

4. Intermediate-term risk. Intermediate-term aggregate exposure

takes into account intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). An intermediate-term aggregate risk

assessment was not conducted because the cypermethrins are acutely toxic and do not increase in potency with repeated dosing. Because the neurotoxicity POD used for acute risk assessment is lower (more protective) than PODs for longer durations of exposure and acute and short-term exposure levels are higher than longer term exposure levels, the acute and short-term aggregate assessments are protective for intermediate-term aggregate risks anticipated from the cypermethrins.

5. Aggregate cancer risk for U.S. population. For the reasons discussed in Unit III.A. (cancer effects are non-linear and appear at higher doses than acute effects) and Unit III.E.2. (chronic exposures are lower than acute exposures), the acute aggregate assessment is protective of potential

cancer risk.

6. 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 the cypermethrin residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Adequate tolerance-enforcement
methods are available in PAM Volume II for determining residues of cypermethrin, zeta-cypermethrin and alpha-cypermethrin in plant (Method I) and livestock (Method II) commodities. Both methods are gas chromatographic methods with electron-capture detection (GC/ECD), and have undergone successful Agency petition method validations (PMVs). Method I has a limit of detection (LOD) of 0.01 ppm, and Method II has LODs of 0.005 ppm in milk, and 0.01 ppm in livestock tissues. These methods are not stereospecific;
thus no distinction is made between residues of cypermethrin (all eight stereoisomers), zeta-cypermethrin(enriched in four isomers) and alphacypermethrin (two isomers).

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 Alimentarius is a joint United Nations Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing
from the Codex level.

There are multiple Codex MRLs for alpha-cypermethrin, but all are in conjunction with MRLs for total cypermethrin isomers (no MRLs havebeen established solely for alphacypermethrin). However, although the
definitions of the isomers covered differ formally between U.S. tolerances and Codex MRLs, the definitions of coverage are effectively harmonized since the
tolerance enforcement methods are not stereospecific, and thus do not distinguish between residues of cypermethrin, zeta-cypermethrin and alpha-cypermethrin. For enforcement purposes, the same moiety is being regulated. As to harmonization of tolerance levels, U.S. tolerances and Codex MRLs are identical for tree nuts, tomatoes, and cattle meat byproducts. However, the proposed U.S. use patterns for all of the other crops for which U.S. tolerances are being established differ from the use patterns underlying the Codex MRLs associated with these crops. Therefore, these U.S.

tolerances cannot be established at the

same level as the Codex MRLs.

C. Response to Comments

There were no comments received on this petition.

D. Revisions to Petitioned-For

Tolerances

No revisions to the tolerance levels in the petition, as proposed by BASF, were necessary. However, all the proposed commodity definitions (except for soybean, seed) were revised to reflect the correct commodity definitions, per the Agency’s current commodity vocabulary. Additionally, appropriate tolerances for alpha-cypermethrin in livestock commodities (which were not proposed by BASF) were added(reflecting those established for zetacypermethrin), based on the potential

for residues in livestock feed items associated with the proposed uses.

V. Conclusion

Therefore, tolerances are established for residues of alpha-cypermethrin ((R)- cyano(3-phenoxyphenyl)methyl (1 S, 3 S)- rel-3-(2,2-dichloroethenyl)-2,2- dimethylcyclopropane carboxylate, in or on cotton, undelinted seed, vegetable, legume, edible podded, subgroup 6A, and sorghum, grain, grain at 0.50 ppm; vegetable, root and tuber, group 1, except sugar beet, pea and bean, succulent shelled, subgroup 6B, and hog, fat at 0.10 ppm; nut, tree, group 14– 12, pea and bean, dried shelled, except soybean, subgroup 6C, corn, field, grain, corn, pop, grain, corn, sweet, kernel plus cob with husks removed, soybean, seed, beet, sugar, roots, cattle, meat byproducts, egg, goat, meat byproducts, hog, meat, horse, meat byproducts, poultry, fat, poultry, meat, and sheep, meat byproducts at 0.05 ppm; vegetable, leafy, group 4 at 10 ppm; Brassica, head and stem, subgroup 5A at 2.0 ppm; rice, grain at 1.5 ppm; vegetable, cucurbit, group 9, vegetable, fruiting, group 8–10, beet, sugar, tops, wheat, grain, cattle, meat, goat, meat, horse, meat, and sheep, meat at 0.20 ppm; fruit, citrus, group 10–10 at 0.35 ppm; citrus, oil at 4.0 ppm; citrus, dried pulp at 1.8 ppm; alfalfa, hay at 15 ppm; cattle, fat, goat, fat, horse, fat, sheep, fat at 1.0 ppm; and milk, fat, reflecting at 0.10 ppm in whole milk at 2.5 ppm. VI. Statutory and Executive Order

Reviews

This final rule establishes tolerances under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types
of actions from review under Executive Order 12866, entitled ‘‘Regulatory Planning and Review’’ (58 FR 51735, October 4, 1993). Because this final rule has been exempted from review under Executive Order 12866, this final rule 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 final rule 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 final rule 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 final rule. In addition, this final rule does not impose any enforceable duty or contain any unfunded mandate


### 7275 Federal Register / Vol. 78, No. 22 / Friday, February 1, 2013 / Rules and Regulations

as described under Title II of the
Unfunded Mandates Reform Act of 1995 (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 of 1995 (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).

food or feed commodities.
