Thiram; Availability of Revised Risk Assessments
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: This notice announces the availability of documents that were
developed as part of EPA's process for making pesticide reregistration
eligibility decisions and tolerance reassessments consistent with the
Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food
Quality Protection Act of 1996 (FQPA). These documents are the human
health and environmental risk assessments and related documents for
thiram. This notice also starts a 60-day public comment period during
which the public is encouraged to submit comments on EPA's preliminary
assessment of benefits of thiram and risk management ideas or proposals
for thiram. This action is in response to a joint initiative between
EPA and the U.S. Department of Agriculture (USDA) to increase
transparency in the tolerance reassessment process for all pesticides.
Comments are to be limited to issues directly associated with thiram
and its benefits raised by the risk assessments, potential risk
reduction options, or other documents placed in the docket. By allowing
access and opportunity for comment on the risk assessments and
potential risk reduction options, EPA is seeking to strengthen
stakeholder involvement and help ensure that our decisions under FQPA
are transparent and based on the best available information.
DATES: Comments, identified by docket ID number OPP-2004-0183, must be
received on or before August 31, 2004.
ADDRESSES: Comments may be submitted electronically, by mail, or
through hand delivery/courier. Follow the detailed instructions as
provided in Unit I. of the SUPPLEMENTARY INFORMATION.

II. Background
EPA has revised the preliminary assessments of the risks of thiram
and identified areas of concern that may require risk mitigation
measures. The Agency's dietary, worker, and ecological risk estimates
for thiram indicate risks of concern. The Agency's dietary risk
estimate indicates acute risk of concern for the general U.S.
population and all population subgroups as a result of foliar
treatments of apples, peaches, and strawberries. EPA's potential risk
mitigation measures for foliar treatments may focus on the apple and
strawberry uses because thiram's main foliar uses are on these crops.
For ecological effects, Agency estimates of exposure resulting from
thiram's foliar usage and turf applications on sod farms, golf courses,
parks, and athletic fields, indicate acute risk to freshwater fish and
invertebrates, estuarine/marine fish and invertebrates, reproductive
risk to birds, and indirect effects to mammals. These risk estimates
also apply to endangered species. Agency estimates of exposure strongly
suggest that thiram-treated seed may pose a risk of causing
reproductive impairments to wild bird species. EPA received additional
information submitted during the Phase 3 comment period pertaining to
thiram's use on seed and impact to avian species, but has not completed
the review of the data. This additional data may be used to further
refine the risk estimates to birds from thiram-treated seed.
Further, worker risks of concern include some loading scenarios for
aerial granular application, some handheld equipment use, and a few
commercial and on-farm seed treatment scenarios.
[[Page 40478]]
EPA has compiled information on thiram's uses and usages, which
will be used in conjunction with comments received during the Phase 3
public comment period to perform a benefits analysis. EPA's preliminary
findings show several other useful protectant fungicides are available
for foliar use based on a review of the USDA Crop Profiles for
California, Oregon, and Washington apples, and California and Florida
strawberries, and communications with several state crop specialists on
the relative importance of thiram in these states.
Thiram's importance for uses on non-residential turf on sod farms
and golf courses appears to be relatively low. Thiram's use on golf
courses may be less than 0.1% of total golf course acres treated.
Thiram's use on sod farms appears to be negligible and may be less than
1% of acres treated.
Thiram's importance for use on seed seems relatively high. Up to
631,000 pounds of thiram (active ingredient) per year are used to treat
about 1.3 billion pounds of seed. About 24 million acres are planted
with thiram-treated seed. The five crops reflecting the distribution of
the acres planted with seed treated with thiram in order of total acres
planted are: Cotton, wheat, barley, oats, and sugar beets. These five
crops comprise a total of greater than 98% of all acres planted with
thiram-treated seed.
EPA has identified some possible preliminary risk reduction options
for thiram. The Agency is awaiting additional data on thiram that could
be used to refine the acute dietary risk assessment; however, based on
the current assessment, eliminating the uses on both strawberries and
apples would bring the dietary risk below the Agency's level of
concern. This option would also reduce the worker and ecological risks
posed by the foliar usage of thiram.
To address the ecological risks posed by thiram's usage on turf, an
option would be to limit the use of thiram to golf course tees and
greens. In relation to addressing these risk concerns, the technical
registrant has submitted a voluntary letter of cancellation that
eliminates the uses of thiram for turf applications to parks, athletic
fields, and commercial landscapes; and all homeowner and retail uses as
for animal repellency on residential lawns or turf, turf being grown
for sale or other commercial use such as sod.
To address the risk concerns for workers, an option would be to add
additional levels of personal protection (e.g., the use of a
respirator) or to eliminate certain application methods (e.g., high
pressure handwand), or use sites (e.g., on-farm seed treatment). In
relation to addressing these risk concerns, the technical registrant
has submitted a voluntary letter of cancellation that eliminates the
on-farm seed treatment of peanuts.
EPA is investigating additional risk reduction options to mitigate
ecological risks of concern posed by the seed treatment uses of thiram.
Commenters are encouraged to discuss the feasibility of restricting the
broadcasting of treated seed and means to ensure that spillage from
drilled seeding applications is removed from the field or buried, as
has been required by the European Union. Alternatively, restrictions
could be placed on which types of seed are treated, the areas of the
country where thiram-treated seed could be planted, and/or the time of
year it is planted. The Agency encourages stakeholders to submit risk
management proposals.
EPA has identified the areas of risk posed by thiram as it is
currently labeled and seeks stakeholder input on how thiram use and
usages can be modified to reduce these risks. EPA encourages
stakeholder input on the following items to assist in developing a risk
mitigation plan:
1. Describe how you use thiram during your production cycles. What
production changes would you make if thiram were not available
including alternative fungicides? What specific pests are being
targeted?
2. How effective are the alternatives to thiram? What are the
differences in costs associated with the use of thiram alternatives?
What impact, if any, do you observe to quality or yield?
3. What is the maximum application rate that you use and how often
do you use it?
4. How important is thiram for the foliar, turf, and seed treatment
uses?
5. How can the Agency reduce ecological risks posed by thiram-
treated seed?
6. How can the Agency reduce occupational risks posed by thiram
(e.g., sewing bags of commercially treated seed or applying thiram with
high pressure handwand)?
III. What Action is the Agency Taking?
EPA is providing an opportunity, through this notice, for
interested parties to provide written comments and input to the Agency
on the risk assessments and preliminary risk reduction options for
thiram. These documents have been developed as part of the public
participation process that EPA and USDA are using to involve the public
in the reassessment of pesticide tolerances under FQPA, and the
reregistration of individual pesticides under FIFRA. A goal of the
public participation process has been to find a more effective way for
the public to participate at critical junctures in the Agency's
development of pesticide risk assessments and risk management
decisions. EPA and USDA began implementing this pilot process in August
1998, to increase transparency and opportunities for stakeholder
consultation. The documents being released to the public through this
notice provide information on the revisions that were made to the
thiram preliminary risk assessments, which were released to the public
on January 26, 2004 (69 FR 3581) (FRL-7341-2), through notices in the
Federal Register. The Agency's human health and environmental risk
assessments and other related documents for thiram are available in the
individual pesticide docket. As additional comments, reviews, and risk
assessment modifications become available, these will also be docketed
for thiram.
In addition, this notice starts a 60-day public participation
period during which the public is encouraged to submit risk management
proposals or other comments on risk management for thiram. The Agency
is providing an opportunity, through this notice, for interested
parties to provide written comments on risk management proposals or
ideas for thiram. Such comments and proposals could address ideas about
how to manage dietary, occupational, or ecological risks on specific
thiram use sites or crops across the United States or in a particular
geographic region of the country. To address dietary risk, for example,
commenters may choose to discuss the feasibility of modifications in
use, and usages of thiram or suggest alternative measures to reduce
residues contributing to dietary exposure. For occupational risks,
commenters may suggest personal protective equipment or technologies to
reduce exposure to workers and pesticide handlers. For ecological
risks, commenters may suggest ways to reduce environmental exposure,
e.g., exposure.
All comments should be submitted by August 31, 2004, using the
methods in Unit I. of the SUPPLEMENTARY INFORMATION. Comments will
become part of the Agency record for thiram.
