The previous ICR estimated 97 existing sources were subject to the standard; however, the RIA indicates there are approximately 90 existing sources. This ICR reflects the most recent information obtained from the 2011 RIA, and contributes to the apparent decrease in the respondent and Agency labor burdens; and (3) there is a slight increase in Agency burden costs from the most-recently approved ICR due to the use of updated labor rates, because this ICR references labor rates from the Bureau of Labor Statistics to calculate respondent burden costs and references labor rates from OPM to calculate Agency burden costs.

If you have any questions regarding the applicability of this action to a particular entity, consult the Chemical Review Manager identified in Table 1. in Unit III. for the pesticide of interest. B. What should I consider as I prepare my comments for EPA? 1. Submitting CBI. Do not submit this information to EPA through regulations.gov or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD–ROM that you mail to EPA, mark the outside of the disk or CD–ROM as CBI and then identify electronically within the disk or CD–ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. 2. Tips for preparing your comments. When submitting comments, remember to: i. Identify the document by docket ID number and other identifying information (subject heading, Federal Register date and page number). ii. Follow directions. The Agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number. iii. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes. iv. Describe any assumptions and provide any technical information and/ or data that you used. v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced. vi. Provide specific examples to illustrate your concerns and suggest alternatives. vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats. viii. Make sure to submit your comments by the comment period deadline identified. 3. Environmental justice. EPA seeks to achieve environmental justice, the fair treatment and meaningful involvement of any group, including minority and/or low income populations, in the development, implementation, and enforcement of environmental laws, regulations, and policies. To help address potential environmental justice E:\FR\FM\26JNN1.SGM 26JNN1 38316 Federal Register / Vol. 78, No. 123 / Wednesday, June 26, 2013 / Notices issues, the Agency seeks information on any groups or segments of the population who, as a result of their location, cultural practices, or other factors, may have atypical or disproportionately high and adverse human health impacts or environmental effects from exposure to the pesticides discussed in this document, compared to the general population. II. Authority EPA is conducting its registration review of the pesticides identified in this document pursuant to section 3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the procedural regulations for registration review at 40 CFR part 155, subpart C. Section 3(g) of FIFRA provides, among other things, that the registrations of pesticides are to be reviewed every 15 years. Under FIFRA, a pesticide product may be registered or remain registered only if it meets the statutory standard for registration given in FIFRA section 3(c)(5). When used in accordance with widespread and commonly recognized practice, the pesticide product must perform its intended function without unreasonable adverse effects on the environment; that is, without any unreasonable risk to man or the environment, or a human dietary risk from residues that result from the use of a pesticide in or on food. III. Registration Reviews As directed by FIFRA section 3(g), EPA is reviewing the pesticide registrations for acetaminophen, clofentezine, fluazinam, hexythiazox, quinclorac, sulfur, and triflumizole to ensure that they continue to satisfy the FIFRA standard for registration—that is, that these pesticides can still be used without unreasonable adverse effects on human health or the environment. At this stage in the registration review process, consistent with the final paper, announced in the Federal Register issue of March 27, 2013 (78 FR 18585) (FRL– 9382–5), jointly developed with the U.S. Department of Agriculture (USDA), the National Marine Fisheries Service, and the U.S. Fish and Wildlife Service (‘‘the Services’’) to enhance opportunities for stakeholder input during pesticide registration reviews and endangered species consultations, draft environmental risk assessments include an evaluation of the potential risks to federally listed endangered and threatened species (hereafter referred to as ‘‘listed species’’). EPA intends to complete a refined assessment of potential risks to individual listed species, as needed. The refined listed species assessments will be based on the recommendations of the National Research Council (NRC), which was tasked with providing advice on ecological risk assessment tools and scientific approaches in developing listed species risk assessments that are compliant with both FIFRA and the Endangered Species Act (ESA). The NRC report, issued April 30, 2013, provides recommendations to ensure scientific soundness and maximize the utility of risk assessment refinements for listed species. Additional information can be found at the following Web site: https://www8.nationalacademies.org/cp/ projectview.aspx?key=49396. Revisions to risk assessments will likely reflect Agency review of the report and any associated methodology and science policy based on the report’s recommendations. Refinements to the listed species assessments may include, but not be limited to, the following: • More detailed, species-specific ecological and biological data. • More detailed and accurate information on chemical use patterns. • Sub-county level spatial proximity data depicting the co-occurrence of potential effects areas and listed species and any designated critical habitat. In the event that a draft risk assessment shows risks of concern to human health or the environment for a specific chemical, EPA reserves the right to initiate mitigation at this stage of registration review. This effort to mitigate a chemical’s risks early in the registration review process is consistent with the Agency’s approach for registration review. Where risks are identified early in the registration review process and opportunities for early mitigation exist, the Agency may pursue those opportunities as they arise, rather then waiting for completion of a chemical’s registration review in order to mitigate risks. The public comment period for the draft risk assessments allows members of the public to provide comments and suggestions for revising the draft risk assessments and for reducing risks. Pursuant to 40 CFR 155.53(c), EPA is providing an opportunity, through this notice of availability, for interested parties to provide comments and input concerning the Agency’s draft human health and ecological risk assessments for acetaminophen, clofentezine, fluazinam, hexythiazox, quinclorac, sulfur, and triflumizole. Such comments and input could address, among other things, the Agency’s risk assessment methodologies and assumptions, as applied in these draft risk assessments. The Agency will consider all comments received during the public comment period and make changes, as appropriate, to the draft human health and ecological risk assessments. EPA will then issue revised risk assessments, if appropriate, explain any changes to the draft risk assessment, and respond to comments. In the Federal Register notice announcing the availability of the revised risk assessments, if the revised risk assessments indicate risks of concern, the Agency may provide a comment period for the public to submit suggestions for mitigating the risks identified in those revised risk assessments before developing proposed registration review decisions on acetaminophen, clofentezine, fluazinam, hexythiazox, quinclorac, sulfur, and triflumizole. At present, EPA is releasing registration review draft risk assessments for the pesticide cases identified in the following table and further described in this unit.

The registration review docket for acetaminophen (EPA– HQ–OPP–2012–0145) opened in the Federal Register issue of March 28, 2012 (77 FR 18810) (FRL–9342–1). Acetaminophen (also known by the brand name Tylenol) is registered for use as a vertebrate pesticide to control the invasive brown tree snake in Guam. The snakes ingest baited mice, which are lethal to the snake. One FIFRA section 3 product is registered, and two FIFRA section 18 registrations are held by USDA Animal Plant Health Inspection Service. The Agency has conducted a quantitative ecological risk and endangered species assessment for acetaminophen based on the available information and on the limited use of this pesticide active ingredient. There was no need for a human health risk assessment due to acetaminophen’s well-studied pharmaceutical use and extremely limited opportunities for exposure from its pesticidal use on Guam. In addition, EPA has determined that no new data are needed to support the registration review decision for acetaminophen. • Clofentezine. The registration review docket for clofentezine (EPA– HQ–OPP–2006–0240) opened in the Federal Register issue of March 28, 2007 (72 FR 14548) (FRL–8118–3). Clofentezine is an acaricide that is currently registered as a liquid formulation for use on almonds, apples, apricots, cherries, Christmas trees, grapes, nectarines, ornamentals (greenhouse and outdoor), peaches, pears, persimmons, and walnuts. There are currently no residential uses associated with clofentezine. The Agency has conducted a human health risk assessment for both dietary (food and drinking water) and occupational exposure pathways. The Agency has also conducted a quantitative ecological risk assessment, which includes a screening-level listed species assessment. EPA acknowledges that further refinements to the listed species assessment will be completed in future revisions and requests public comment on specific areas that will reduce the uncertainties associated with the characterization of risk to listed species identified in the current assessment. • Fluazinam.

SUPPLEMENTARY INFORMATION: DATES: Background Section 108 (a) of the Clean Air Act directs the Administrator to identify certain pollutants, which among other things, ‘‘cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare’’ and to issue air quality criteria for them. These air quality criteria are to ‘‘accurately reflect the latest scientific knowledge useful in indicating the kind and extent of all identifiable effects on public health or welfare which may be expected from the presence of [a] pollutant in the ambient air. . . .’’ Under section 109 of the Act, EPA is then to establish NAAQS for each pollutant for which EPA has issued criteria. Section 109 (d) of the Act subsequently requires periodic review and, if appropriate, revision of existing air quality criteria to reflect advances in scientific knowledge on the effects of the pollutant on public health or welfare. EPA is also to periodically review and, if appropriate, revise the NAAQS, based on the revised air quality criteria. Pb is one of six ‘‘criteria’’ pollutants for which EPA has established NAAQS. Periodically, EPA reviews the scientific basis for these standards by preparing an Integrated Science Assessment (ISA) (formerly called an Air Quality Criteria Document). The ISA provides a concise review, synthesis, and evaluation of the most policy-relevant science to serve as a scientific foundation for the review of the NAAQS.

Registration Review; Draft Human Health and Ecological Risk 
Assessments; Notice of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of EPA's draft human 
health and ecological risk assessments for the registration review of 
acetaminophen, clofentezine, fluazinam, hexythiazox, quinclorac, 
sulfur, and triflumizole and opens a public comment period on these 
documents. Registration review is EPA's periodic review of pesticide 
registrations to ensure that each pesticide continues to satisfy the 
statutory standard for registration, that is, the pesticide can perform 
its intended function without unreasonable adverse effects on human 
health or the environment. As part of the registration review process, 
the Agency has completed comprehensive draft risk assessments for each 
of the subject chemicals and is making them available for public 
comment. After reviewing comments received during the public comment 
period, EPA will issue revised risk assessments, if appropriate, 
explain any changes to the draft risk assessments, and respond to 
comments and may request public input on risk mitigation before 
completing a proposed registration review decision for each of the 
chemicals. Through this program, EPA is ensuring that each pesticide's 
registration is based on current scientific and other knowledge, 
including its effects on human health and the environment.

    3. Environmental justice. EPA seeks to achieve environmental 
justice, the fair treatment and meaningful involvement of any group, 
including minority and/or low income populations, in the development, 
implementation, and enforcement of environmental laws, regulations, and 
policies. To help address potential environmental justice

[[Page 38316]]

issues, the Agency seeks information on any groups or segments of the 
population who, as a result of their location, cultural practices, or 
other factors, may have atypical or disproportionately high and adverse 
human health impacts or environmental effects from exposure to the 
pesticides discussed in this document, compared to the general 
population.

II. Authority

    EPA is conducting its registration review of the pesticides 
identified in this document pursuant to section 3(g) of the Federal 
Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the procedural 
regulations for registration review at 40 CFR part 155, subpart C. 
Section 3(g) of FIFRA provides, among other things, that the 
registrations of pesticides are to be reviewed every 15 years. Under 
FIFRA, a pesticide product may be registered or remain registered only 
if it meets the statutory standard for registration given in FIFRA 
section 3(c)(5). When used in accordance with widespread and commonly 
recognized practice, the pesticide product must perform its intended 
function without unreasonable adverse effects on the environment; that 
is, without any unreasonable risk to man or the environment, or a human 
dietary risk from residues that result from the use of a pesticide in 
or on food.

III. Registration Reviews

    As directed by FIFRA section 3(g), EPA is reviewing the pesticide 
registrations for acetaminophen, clofentezine, fluazinam, hexythiazox, 
quinclorac, sulfur, and triflumizole to ensure that they continue to 
satisfy the FIFRA standard for registration--that is, that these 
pesticides can still be used without unreasonable adverse effects on 
human health or the environment.
    At this stage in the registration review process, consistent with 
the final paper, announced in the Federal Register issue of March 27, 
2013 (78 FR 18585) (FRL-9382-5), jointly developed with the U.S. 
Department of Agriculture (USDA), the National Marine Fisheries 
Service, and the U.S. Fish and Wildlife Service (``the Services'') to 
enhance opportunities for stakeholder input during pesticide 
registration reviews and endangered species consultations, draft 
environmental risk assessments include an evaluation of the potential 
risks to federally listed endangered and threatened species (hereafter 
referred to as ``listed species''). EPA intends to complete a refined 
assessment of potential risks to individual listed species, as needed. 
The refined listed species assessments will be based on the 
recommendations of the National Research Council (NRC), which was 
tasked with providing advice on ecological risk assessment tools and 
scientific approaches in developing listed species risk assessments 
that are compliant with both FIFRA and the Endangered Species Act 
(ESA). The NRC report, issued April 30, 2013, provides recommendations 
to ensure scientific soundness and maximize the utility of risk 
assessment refinements for listed species. Additional information can 
be found at the following Web site: https://www8.nationalacademies.org/cp/projectview.aspx?key=49396. Revisions to risk assessments will 
likely reflect Agency review of the report and any associated 
methodology and science policy based on the report's recommendations. 
Refinements to the listed species assessments may include, but not be 
limited to, the following:
     More detailed, species-specific ecological and biological 
data.
     More detailed and accurate information on chemical use 
patterns.
     Sub-county level spatial proximity data depicting the co-
occurrence of potential effects areas and listed species and any 
designated critical habitat.
    In the event that a draft risk assessment shows risks of concern to 
human health or the environment for a specific chemical, EPA reserves 
the right to initiate mitigation at this stage of registration review. 
This effort to mitigate a chemical's risks early in the registration 
review process is consistent with the Agency's approach for 
registration review. Where risks are identified early in the 
registration review process and opportunities for early mitigation 
exist, the Agency may pursue those opportunities as they arise, rather 
then waiting for completion of a chemical's registration review in 
order to mitigate risks. The public comment period for the draft risk 
assessments allows members of the public to provide comments and 
suggestions for revising the draft risk assessments and for reducing 
risks.
    Pursuant to 40 CFR 155.53(c), EPA is providing an opportunity, 
through this notice of availability, for interested parties to provide 
comments and input concerning the Agency's draft human health and 
ecological risk assessments for acetaminophen, clofentezine, fluazinam, 
hexythiazox, quinclorac, sulfur, and triflumizole. Such comments and 
input could address, among other things, the Agency's risk assessment 
methodologies and assumptions, as applied in these draft risk 
assessments. The Agency will consider all comments received during the 
public comment period and make changes, as appropriate, to the draft 
human health and ecological risk assessments. EPA will then issue 
revised risk assessments, if appropriate, explain any changes to the 
draft risk assessment, and respond to comments. In the Federal Register 
notice announcing the availability of the revised risk assessments, if 
the revised risk assessments indicate risks of concern, the Agency may 
provide a comment period for the public to submit suggestions for 
mitigating the risks identified in those revised risk assessments 
before developing proposed registration review decisions on 
acetaminophen, clofentezine, fluazinam, hexythiazox, quinclorac, 
sulfur, and triflumizole. At present, EPA is releasing registration 
review draft risk assessments for the pesticide cases identified in the 
following table and further described in this unit.

------------------------------------------------------------------------

     Acetaminophen. The registration review docket for 
acetaminophen (EPA-HQ-OPP-2012-0145) opened in the Federal Register 
issue of March 28, 2012 (77 FR 18810) (FRL-9342-1). Acetaminophen (also 
known by the brand name Tylenol) is registered for use as a vertebrate 
pesticide to control the invasive brown tree snake in Guam. The snakes 
ingest baited mice, which are lethal to the snake. One FIFRA section 3 
product is registered, and two FIFRA section 18 registrations are held 
by USDA Animal Plant Health Inspection Service. The Agency has 
conducted a quantitative ecological risk and endangered species 
assessment for acetaminophen based on the available information and on 
the limited use of this pesticide active ingredient. There was no need 
for a human health risk assessment due to acetaminophen's well-studied 
pharmaceutical use and extremely limited opportunities for exposure 
from its pesticidal use on Guam. In addition, EPA has determined that 
no new data are needed to support the registration review decision for 
acetaminophen.
     Clofentezine. The registration review docket for 
clofentezine (EPA-HQ-OPP-2006-0240) opened in the Federal Register 
issue of March 28, 2007 (72 FR 14548) (FRL-8118-3). Clofentezine is an 
acaricide that is currently registered as a liquid formulation for use 
on almonds, apples, apricots, cherries, Christmas trees, grapes, 
nectarines, ornamentals (greenhouse and outdoor), peaches, pears, 
persimmons, and walnuts. There are currently no residential uses 
associated with clofentezine. The Agency has conducted a human health 
risk assessment for both dietary (food and drinking water) and 
occupational exposure pathways. The Agency has also conducted a 
quantitative ecological risk assessment, which includes a screening-
level listed species assessment. EPA acknowledges that further 
refinements to the listed species assessment will be completed in 
future revisions and requests public comment on specific areas that 
will reduce the uncertainties associated with the characterization of 
risk to listed species identified in the current assessment.
     Fluazinam. The registration review docket for fluazinam 
(EPA-HQ-OPP-2009-0039) opened in the Federal Register issue of 
September 23, 2009 (74 FR 48559) (FRL-8434-6). Fluazinam is a pyridine 
fungicide registered for agricultural use on a variety of crops, 
including but not limited to melons, peanuts, peppers/eggplants, 
potatoes, and soybeans. Fluazinam is also registered for non-
agricultural use on golf course turf. The Agency has conducted a human 
health risk assessment for dietary (food and drinking water), 
residential and occupational exposure pathways. An addendum to the most 
recent human health risk assessment was completed to incorporate 
information received shortly after the completion of the risk 
assessment. The addendum and risk assessment are available in the 
registration review docket. The Agency has also conducted a 
quantitative ecological risk assessment, which includes a screening-
level listed species assessment. EPA acknowledges that further 
refinements to the listed species assessment will be completed in 
future revisions and requests public comment on specific areas that 
will reduce the uncertainties associated with the characterization of 
risk to listed species identified in the current assessment.
     Hexythiazox. The registration review docket for 
hexythiazox (EPA-HQ-OPP-2006-0114) opened in the Federal Register issue 
of February 2, 2007 (72 FR 5050) (FRL-8113-1). Hexythiazox is an 
acaricide that acts primarily as a mite growth inhibitor/ovicide and is 
used to control mites. It is registered for use on a variety of 
agricultural crops, turf, and various residential plants. The Agency 
has conducted a human health risk assessment for dietary (food and 
drinking water), residential, and occupational exposure pathways. The 
Agency has conducted a quantitative ecological risk assessment, which 
includes a screening-level listed species assessment. EPA acknowledges 
that further refinements to the listed species assessment will be 
completed in future revisions and requests public comment on specific 
areas that will reduce the uncertainties associated with the 
characterization of risk to listed species identified in the current 
assessment.
     Quinclorac. The registration review docket for quinclorac 
(EPA-HQ-OPP-2007-1135) opened in the Federal Register issue of December 
19, 2007 (72 FR 71893) (FRL-8342-9). Quinclorac is an herbicide for the 
selective post-emergent control of various annual grasses and broadleaf 
weeds. The variety of end-use products containing quinclorac are 
currently registered on rice, sorghum, and wheat. Additionally, 
quinclorac is registered for use by commercial applicators and 
homeowners on lawns, parks, in and around ornamentals, and golf 
courses. The Agency has conducted a human health risk assessment for 
dietary (food and drinking water), residential, and occupational 
exposure pathways in support of registration review, and for new 
proposed use on rhubarb, and low growing berry (except for strawberry), 
subgroup 13-07H. The Agency has conducted a quantitative ecological 
risk assessment, which includes a screening-level listed species 
assessment. EPA acknowledges that further refinements to the listed 
species assessment will be completed in future revisions and requests 
public comment on specific areas that will reduce the uncertainties 
associated with the characterization of risk to listed species 
identified in the current assessment.
     Sulfur. The registration review docket for sulfur (EPA-HQ-
OPP-2008-0176) opened in the Federal Register issue of March 26, 2008 
(73 FR 16011) (FRL-8356-4). Elemental sulfur is a naturally occurring 
component of the earth's core and crust and is ubiquitous in the 
environment. Sulfur has been used as a pesticide in the United States 
since the 1920s, and is currently registered for use as an insecticide 
and fungicide on a wide range of field and greenhouse-grown food and 
feed crops, livestock (and livestock quarters), and indoor and outdoor 
residential sites. Use sites include berries, field crops, ornamentals, 
pets (dogs), root crops, tree fruit, vegetables, and turf (including 
residential lawns and golf courses). Sulfur is also registered for use 
in gas cartridge products, which are used for vertebrate pest control 
in a variety of sites. The Agency has conducted a qualitative human 
health risk assessment. The Agency has also conducted a quantitative 
ecological risk assessment, which includes a screening-level listed 
species assessment. EPA

[[Page 38318]]

acknowledges that further refinements to the listed species assessment 
will be completed in future revisions and requests public comment on 
specific areas that will reduce the uncertainties associated with the 
characterization of risk to listed species identified in the current 
assessment. The human health risk assessment includes all uses of 
sulfur, including gas cartridges. The most recent ecological risk 
assessment includes all uses except gas cartridges. A separate 
ecological risk assessment for gas cartridge uses was conducted in 2010 
and can be found in the sulfur registration review docket.
     Triflumizole. The registration review docket for 
triflumizole (EPA-HQ-OPP-2006-0115) opened in the Federal Register 
issue of March 28, 2007 (72 FR 14548) (FRL-8118-3). Triflumizole is a 
broad spectrum, imidazole fungicide (group 3) that inhibits ergosterol 
biosynthesis in fungi. It is registered for use on a variety of 
agricultural crops, ornamentals in greenhouses/shade houses, interior 
scapes, and Christmas trees/conifers on nurseries and plantations. It 
is also registered for use as a pre-plant pineapple seed treatment. The 
Agency has conducted a human health risk assessment for dietary (food 
and drinking water), residential and occupational exposure pathways. 
The Agency has also conducted a quantitative ecological risk 
assessment, which includes a screening-level listed species assessment. 
EPA acknowledges that further refinements to the listed species 
assessment will be completed in future revisions and requests public 
comment on specific areas that will reduce the uncertainties associated 
with the characterization of risk to listed species identified in the 
current assessment.
