methyl 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 risk and draft ecological risk assessments for aldicarb,
bensulide, coumaphos, ethalfluralin, and pirimiphos-methyl 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 a
comprehensive draft human health and ecological risk assessments for
all aldicarb, bensulide, coumaphos, ethalfluralin, and pirimiphos-
methyl uses. After reviewing comments received during the public
comment period, EPA will issue a revised risk assessment, explain any
changes to the draft risk assessment, and respond to comments and may
request public input on risk mitigation before completing a proposed
registration review decision for aldicarb, bensulide, coumaphos,
ethalfluralin, and pirimiphos-methyl. Through this program, EPA is
ensuring that each pesticide's registration is based on

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 preparing and submitting
your comments, see the commenting tips at http://www.epa.gov/dockets/comments.html.
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 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 aldicarb, bensulide,
coumaphos, ethalfluralin, and pirimiphos-methyl 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) (7 U.S.C. 136a(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
registration for aldicarb, bensulide, coumaphos, ethalfluralin, and
pirimiphos-methyl to ensure that it continues to satisfy the FIFRA
standard for registration--that is, that aldicarb, bensulide,
coumaphos, ethalfluralin, and pirimiphos-methyl can still be used
without unreasonable adverse effects on human health or the
environment.

Aldicarb. Draft Human Health and Ecological Risk Assessments (EPA-
HQ-OPP-2012-0161). Aldicarb is a systemic carbamate insecticide,
acaricide, and nematicide registered for use on cotton, dry beans,
peanuts, soybeans, sugar beets, and sweet potatoes. It is not
registered for non-agricultural/residential use. EPA conducted a
comprehensive human health risk assessment including a highly refined
acute dietary exposure assessment for all existing food uses of
aldicarb. Acute dietary exposure estimates for drinking water as well
as food and drinking water combined are of concern. A commodity
specific analysis (CSA) was conducted to obtain estimates of acute
exposure and risk following a single consumption of a single commodity.
Exposure estimates were above the level of concern for children
following consumption of sweet potatoes or potatoes. Additionally,
there are short- and intermediate-term occupational handler risk
estimates of concern for the registered uses of aldicarb with label-
specified personal protective equipment. EPA also conducted a screening
level ecological risk assessment and identified potential risks to both
aquatic and terrestrial non-target organisms. The assessments did not
cover the EDSP component of this registration review case, nor does it
include a full pollinator assessment or a complete endangered species
assessment.
Bensulide. Draft Human Health and Ecological Risk Assessments (EPA-
HQ-OPP-2008-0022). Bensulide is a systemic organophosphate herbicide
registered to control grasses and broadleaf weeds in a variety of
agricultural (e.g., lettuce, cantaloupe, broccoli) and non-agricultural
(golf course, turf farm, residential lawn, rights-of-way, and
landscaping) settings, and is usually applied to bare ground before
crops are planted. EPA conducted a comprehensive human health risk
assessment and identified risks of concern for dietary, residential,
occupational, and spray drift exposures. The bensulide risk assessment
retained the FQPA 10x safety factor due to the uncertainty in the human
dose-response relationship for neuro-developmental effects. EPA also
conducted an ecological risk assessment for bensulide, which identified
risks of concern for non-listed species for birds, reptiles, and
terrestrial-phase amphibians; mammals; freshwater fish and aquatic-
phase amphibians; marine/estuarine fish; freshwater invertebrates; and
aquatic vascular plants. Neither an endangered species assessment nor a
pollinator assessment been completed for bensulide at this time.
Bensulide is on the second list of chemicals for tier one screening
under the Endocrine Disruptor Screening Program (EDSP).
Coumaphos. Draft Human Health and Ecological Risk Assessments (EPA-
HQ-OPP-2008-0023). Coumaphos is an organophosphate acaricide. It is
used to control ticks and mites on livestock, as well as to control
varroa mites and small hive beetles in beehives. The human health risk
assessment for coumaphos found dietary risks of concern, with food
(beef meat) being the driver in the steady state risk estimates. In
addition, almost all of the occupational exposure scenarios show risks
of concern for both dermal and inhalation routes of exposure at varying
levels of personal protection equipment and all formulations with the
exception of liquid. The coumaphos risk assessment retained the FQPA
10x safety factor due to the uncertainty in human dose-response
relationship for neuro-developmental effects. Coumaphos is expected to
pose an acute risk to birds. Coumaphos is not expected to pose a risk
to endangered or non-endangered mammals because of its limited use
pattern. Coumaphos usage on cattle may pose a high acute risk to
aquatic invertebrates. Coumaphos is not expected to pose chronic or
acute risks to listed or non-listed fish. Neither a comprehensive
endangered species assessment nor a pollinator assessment has been
completed for coumaphos at this time. Coumaphos is on the second list
of chemicals for Tier 1 screening under EDSP.
Ethalfluralin. Draft Human Health and Ecological Risk Assessments
(EPA-HQ-OPP-2011-0094). Ethalfluralin is a preemergence herbicide used
to control a variety of annual grasses and broadleaf weeds on
agricultural sites. Ethalfluralin has multiple end-use products that
are registered for use on various agricultural crops. EPA conducted a
comprehensive human health risk assessment and did not identify any
risks of concern. EPA also conducted an ecological risk assessment.
Potential risks to aquatic animals, aquatic and terrestrial plants, and
mammals were identified. The assessments did not cover the EDSP
component of this registration review case, nor does it include either
a full pollinator assessment or a complete endangered species
assessment.
Pirimiphos-methyl. Draft Human Health Risk and Ecological
Assessments (EPA-HQ-OPP-2009-0056). Pirimiphos-methyl is a member of
the organophosphate class of pesticides. Currently, it is registered
for use as an insecticide in cattle ear tags, and on post-harvest
stored grain/seeds (sorghum and corn). There are two special local need
FIFRA section 24(c) registrations: A fogger treatment on iris bulbs in
Washington, and a fogger and drench treatment on gladiola bulbs in
Michigan. EPA conducted a human health risk assessment, and did not
identify any risks of concern for dietary or residential exposures.
However, risks of concern were identified for occupational exposure and
for all handler scenarios. The pirimiphos-methyl risk assessment
retained the FQPA 10x safety factor due to the uncertainty in human
dose-response relationship for neuro-developmental effects. EPA also
conducted a quantitative ecological risk assessment and identified
potential risks to terrestrial and aquatic invertebrates. A complete
endangered species assessment nor a pollinator assessment has been
completed for pirimiphos-methyl. The assessments did not cover the EDSP
component of this registration review case.
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 aldicarb, bensulide, coumaphos,
ethalfluralin, and pirimiphos-methyl. Such comments and input could
address, among other things, the Agency's risk assessment methodologies
and assumptions, as applied to this draft risk assessment. 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 a revised risk
assessment, explain any changes to the draft risk assessment, and
respond to comments. In the Federal Register notice announcing the
availability of the revised risk assessment, if the revised risk
assessment indicates risks of concern, the Agency may provide a comment
period for the public to submit suggestions for mitigating the risk
identified in the revised risk assessment before developing a proposed
registration review decision on aldicarb, bensulide, coumaphos,
ethalfluralin, and pirimiphos-methyl.
