EPA's Science Advisory Board (SAB) Staff Office has announced two meetings for the SAB Chemical Assessment Advisory Committee (CAAC), augmented for the review of the draft IRIS assessment of ammonia (CAAC-Ammonia panel). The first meeting is a public teleconference scheduled for June 2, 2014. The second is a face-to face panel meeting scheduled for July 14-16, 2014 in Arlington, VA.

The SAB CAAC-Ammonia panel will review this draft assessment. Details about the meeting dates, times, and location are available via the Federal Register Notice posted on March 25, 2014. The SAB provided information on how the public can participate in the external peer review meetings, as well as instructions about how to provide comments to the SAB in the notice.
