Impact/Purpose:
The Integrated Plan for Review of the NAAQS for CO {U.S. EPA, 2008 #8615} identifies key policy-relevant questions that provide a framework for this review of the scientific evidence. These questions frame the entire review of the NAAQS, and thus are informed by both science and policy considerations. The ISA organizes and presents the scientific evidence such that it, when considered along with findings from risk analyses and policy considerations, will help the EPA address these questions during the NAAQS review:
Description:
EPA announced that the First External Review Draft of the Integrated Science Assessment (ISA) for Carbon Monoxide (CO) and related Annexes was made available for independent peer review and public review. This draft ISA document represents a concise synthesis and evaluation of the most policy-relevant science and will ultimately provide the scientific bases for EPA's decision regarding whether the current standards for CO sufficiently protect public health and the environment.
