EPA announced in the November 18 Federal Register that it is requesting public nominations of scientific experts for appointment to EPA’s Science Advisory Board (SAB) Chemical Assessment Advisory Committee. The primary purpose of this new committee is to review chemical assessments. The exact number for new committee members has not yet been determined. EPA will also consult with the committee on questions regarding the Integrated Risk Information System (IRIS) Program. This action continues the agency’s efforts to further strengthen the IRIS program. IRIS is a publicly available online database that provides high quality science-based human health assessments used to inform the agency’s decisions on protecting public health and the environment.
