[UPDATE] To provide the public with additional time to prepare, EPA SAB staff office is rescheduling the February 18-20 meeting of the SAB Chemical Assessment Advisory Committee (CAAC). The EPA SAB staff office will announce a new date in the near future.
[UPDATE] In August 2013, EPA submitted a revised draft IRIS assessment of ammonia to the agency's Science Advisory Board (SAB) and posted this draft on the IRIS website. EPA had previously released a draft of the assessment for public comment, held a public meeting about the draft, and then revised it based on the comments received. The SAB Chemical Assessment Advisory Committee (CAAC), augmented with additional experts, will review this draft assessment. Details about the meeting dates, times, and location are available via the Federal Register Notice posted on January 31, 2014. The SAB provided information on how the public can participate in the external peer review meeting, as well as instructions about how to provide comments to the SAB in the notice. Additional information on the SAB review of ammonia is on the SAB website.
