Federal Register Notices
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 trimethylbenzenes (CAAC-Trimethylbenzenes panel). The first meeting is a public teleconference scheduled for May 22, 2014. The second is a face-to face panel meeting scheduled for June 17-19, 2014 in Arlington, VA. Additional information about participation in the external peer review meetings, including how to provide comments to the SAB, are now available on the SAB review of trimethylbenzenes website and via the Federal Register.
In August 2013, EPA submitted a revised draft IRIS assessment of trimethylbenzenes 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 CAAC-Trimethylbenzenes 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. Additional information on the SAB review of trimethylbenzenes is on the SAB website.
