Integrated Science Assessment (ISA) for Particulate Matter (Second External Review Draft, Jul 2009)
EPA is announcing the release of the draft document, Integrated Science Assessment for Particulate Matter (Second External Review Draft) for public review and comment as described in the July 31, 2009 Federal Register Notice. Please see Additional Information for more information and specific details for providing comments. The deadline for submitting comments is October 13, 2009 (see FR notices for extension details).

Impact/Purpose:
Key information and judgments formerly contained in an Air Quality Criteria Document (AQCD) for PM are incorporated in this assessment. Additional details of the pertinent literature published since the last review, as well as selected older studies of particular interest, are included in a series of annexes. This ISA thus serves to update and revise the evaluation of the scientific evidence available at the time of the previous review of the NAAQS for PM that was concluded in 2006.
Description:
EPA has announced that the Second External Review Draft of the Integrated Science Assessment (ISA) for Particulate Matter (PM) have been made available for independent peer review and public review. The ISA reflects the latest scientific knowledge useful in indicating the kind and extent of identifiable effects on public health which may be expected from the presence of [a] pollutant in ambient air (42 U.S.C. 7408). 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 National Ambient Air Quality Standards (NAAQS) for PM sufficiently protects public health and the environment.
