[Update] New Schedule for IRIS Acrylonitrile Assessment Announced
EPA has developed a new schedule for completing the IRIS Acrylonitrile assessment, which can be found in IRIS Track (IRISTrack - Acrylonitrile). EPA has decided to make further revisions to the acrylonitrile assessment to more fully address scientific issues in the assessment. The revised draft acrylonitrile assessment will be released for public comment and rigorous, independent expert peer review. EPA will seek to have the peer review performed by the new Chemical Assessment Advisory Committee that is being formed under the auspices of the Science Advisory Board.
