Start Preamble

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.
