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.
