June 2006 Public Workshop
EPA held a public workshop Tuesday, June 27, 2006 to discuss the process the Agency uses to review its National Ambient Air Quality Standards. The agency is examining the process to determine whether it can be strengthened and streamlined. In April, an agency workgroup issued recommendations for improving the process used to review the standards.
The workshop provided the public the opportunity to present their views on the review process, and to discuss the process with EPA officials. This workshop did not cover issues related to the ongoing review of any specific air quality standard.
