The U.S. EPA Office of Research and Development's National Center for Environmental Assessment (NCEA) is preparing an Integrated Science Assessment (ISA) as part of the review of the primary National Ambient Air Quality Standards (NAAQS) for oxides of sulfur (SOX) (for which the indicator is sulfur dioxide [SO2]). This ISA will update the scientific assessment presented in the Integrated Science Assessment for Sulfur Oxides Health Criteria (EPA 600/R-08/047F), published in September 2008. Interested parties are invited to assist the EPA in developing and refining the scientific information base for the review of the NAAQS for SOX by submitting recent research studies that have been published, accepted for publication, or presented at a public scientific meeting. The EPA is also announcing that a workshop entitled ``Kickoff Workshop to Inform EPA's Review of the Primary SO2 NAAQS'' is being organized by NCEA and the EPA Office of Air and Radiation's Office of Air Quality Planning and Standards (OAQPS). The workshop will be held June 12-13, 2013, in Research Triangle Park, North Carolina. The workshop will be open to attendance by interested public observers on a first-come, first-served basis up to the limits of available space. Additionally, in the near future, the EPA Scientific Advisory Board (SAB) will be forming a Clean Air Scientific Advisory Committee (CASAC) panel for the SO2 NAAQS health review.
