ENVIRONMENTAL PROTECTION AGENCY

Carbofuran; Notice of Availability of Revised Surface Water
Exposure Assessment

AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.

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

SUMMARY: This notice announces the availability of EPA's revised
surface water exposure assessment for the pesticide carbofuran. This
revised assessment reflects the most current soil input parameters for
the surface water exposure modeling done for the dietary risk
assessment for carbofuran. While the underlying information based on
soil type has been updated, the Agency's ultimate risk conclusions have
not changed. The new drinking water exposure assessment dated August
20, 2008, entitled ``Updated Refinements of the Drinking Water Exposure
Assessment for the Use of Carbofuran on Corn and Melons,'' is in the
carbofuran docket.

II. Background

A. What Action is the Agency Taking?

    Upon further review of its underlying assessments, the Agency has
updated its drinking water exposure assessment for the pesticide
carbofuran to reflect the most current soil input parameters for the
surface water source drinking water exposure modeling. Soil information
for 8 of the 11 scenarios has been updated to more closely resemble
soils in the areas where the scenarios for these crops were modeled. Of
the 11 scenarios, 2 resulted in concentrations that remained largely
unchanged (Minnesota corn and Nebraska corn); and 6 scenarios resulted
in concentrations that decreased slightly (Iowa corn, Indiana corn,
Kansas corn, Michigan melon, Missouri melon, and New Jersey melon). The
remaining 3 scenarios (Illinois corn, Texas corn, and Florida melons)
were not modified and remain unchanged. Despite the revisions to
certain of the underlying assessments from use of the more recent soil
types, the Agency's ultimate risk conclusions regarding carbofuran's
overall dietary risks remain unchanged. EPA is providing notice of its
revised assessments to allow the public the opportunity to comment on
the Agency's revisions during the comment period on its proposed
tolerance revocations.
    The updated exposure assessment, dated August 20, 2008, entitled
``Updated Refinements of the Drinking Water Exposure Assessment for the
Use of Carbofuran on Corn and Melons,'' is in the carbofuran docket
(EPA-HQ-OPP-2005-0162) at http://www.regulations.gov.
