Pesticide Chemicals; Registration Review; Draft Human Health and 
Ecological Risk Assessment; 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 
chlorfenapyr, fenoxaprop-p-ethyl, flumiclorac-pentyl, maleic hydrazide, 
sulfentrazone, and tebuthiuron 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 draft human health and ecological 
risk assessments, including an endangered species assessment, for all 
uses of the previously listed pesticide chemicals. After reviewing 
comments received during the public comment period, EPA will issue 
revised risk assessments, explain any changes to the draft risk 
assessments, and respond to comments and may request public input on 
risk mitigation before completing proposed registration review 
decisions for the previously listed pesticide 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.

    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 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 chlorfenapyr, 
fenoxaprop-p-ethyl, flumiclorac-pentyl, maleic hydrazide, 
sulfentrazone, and tebuthiuron 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

 A. What action is the Agency taking?

    As directed by FIFRA section 3(g), EPA is reviewing the pesticide 
registrations for chlorfenapyr, fenoxaprop-p-ethyl, flumiclorac-pentyl, 
maleic hydrazide, sulfentrazone, and tebuthiuron 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.
    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 chlorfenapyr, fenoxaprop-p-ethyl, 
flumiclorac-pentyl, maleic hydrazide, sulfentrazone, and tebuthiuron. 
Such comments and input could address, among other things, the Agency's 
risk assessment methodologies and assumptions, as applied to 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, explain any changes to the draft risk 
assessments, 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 risk identified in the revised risk assessments. At 
present, EPA is releasing registration review draft risk assessments 
for the pesticide cases identified in the following table and further 
described after the table.

     Chlorfenapyr. Chlorfenapyr is an insecticide/
miticide used to control a wide range of mites and insects such as 
caterpillars, centipedes, thrips, fungus gnats, ants, cockroaches, 
beetles, bed bugs, silverfish, spiders, and termites. Chlorfenapyr is 
registered for use on greenhouse food and non-food crops, and as an 
insecticide/termiticide for use on indoor and outdoor residential 
sites, food/feed handling areas, indoor and outdoor commercial sites 
(including sewers), and indoor medical sites. EPA has completed a draft 
human health risk assessment for all chlorfenapyr uses. In addition, 
the Agency has determined that there is limited outdoor environmental 
exposure from the use of chlorfenapyr and has come to a no-effect 
determination for endangered species.
     Fenoxaprop-p-ethyl. Fenoxaprop-p-ethyl is an 
herbicide used to control weeds on barley, cotton, rice, soybeans, and 
wheat. It is also registered for non-agricultural use on conservation 
reserve lands, ornamentals, rights-of-way, and turf. EPA has completed 
draft human

[[Page 37314]]

health and ecological risk assessments, including a screening-level 
listed species assessment, for all fenoxaprop-p-ethyl uses. 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.
     Flumiclorac-pentyl. Flumiclorac-pentyl is a 
post-emergence herbicide registered for use on field corn, soybeans, 
cotton, and a variety of non-cropped areas. EPA has completed draft 
human health and ecological risk assessments, including a screening-
level listed species assessment, for all flumiclorac-pentyl uses. 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.
     Maleic Hydrazide. Maleic hydrazide is an 
herbicide and plant growth regulator used on tobacco, potatoes, onions, 
non-bearing citrus, turf, utility and highway rights-of-way, airports, 
industrial land, lawns, recreational areas, ornamental shade trees and 
ornamental plants. EPA has completed draft human health and ecological 
risk assessments, including a screening-level listed species 
assessment, for all maleic hydrazide uses. 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.
    Sulfentrazone. Sulfentrazone is an herbicide 
registered for use to control a variety of broadleaf weeds on several 
agricultural crops, ornamental turf/plants, residential lawns, and 
recreational areas such as golf courses. EPA has completed draft human 
health and ecological risk assessments, including a screening-level 
listed species assessment, for all sulfentrazone uses. 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.
    Tebuthiuron. Tebuthiuron is a systemic, 
relatively non-selective herbicide used to control broadleaf and woody 
weeds, grasses and brush on feed crop sites (pasture and rangeland) and 
a variety of non-food crop sites. EPA has completed draft human health 
and ecological risk assessments, including a screening-level listed 
species assessment, for all tebuthiuron uses. 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.
