Common Effects Methodology Regional Stakeholder Meeting January 11 -22, 2010

The U.S. Environmental Protection Agency held six regional public meetings in January 2010 to solicit stakeholder input on its initial thinking regarding a common effects assessment process as well the scope and content of future white papers. The meetings were held in the EPA regions: Regions 2, 4, 5, 7, 9 (Oakland, CA) and 10.

The five presentations for the regional meetings laid out the need for this effort, the process the EPA would use, and the agency’s initial thinking on major issues regarding common effects assessments using available data in an effort to solicit stakeholder input on the EPA's initial thinking regarding a common effects assessment process.
