 2009 Final Report: Integrated Science Assessment for

 Particulate Matter

Notice

EPA is announcing the availability of the final Integrated Science Assessment for Particulate Matter as described in the December

 15, 2009 Federal Register Notice.

Report Information

EPA has released the final Integrated Science Assessment (ISA) for Particulate Matter (PM). This is EPA’s latest evaluation of the

 scientific literature on the potential human health and welfare effects associated with ambient exposures to particulate matter

 (PM). The development of this document is part of the Agency's periodic review of the national ambient air quality standards

 (NAAQS) for PM. The recently completed PM ISA and supplementary annexes, in conjunction with additional technical and

 policy assessments developed by EPA’s Office of Air and Radiation, will provide the scientific basis to inform EPA decisions

 related to the review of the current PM NAAQS.

Background

PM is one of six principal (or criteria) pollutants for which EPA has established

 NAAQS. Periodically, EPA reviews the scientific basis for these standards by

 preparing an ISA (formerly called an Air Quality Criteria Document). The ISA and

 supplementary annexes, in conjunction with additional technical and policy

 assessments, provide the scientific basis for EPA decisions on the adequacy of the

 current NAAQS and the appropriateness of possible alternative standards. The

 Clean Air Scientific Advisory Committee (CASAC), an independent science advisory

 committee whose existence and whose review and advisory functions are mandated

 by Section 109 (d) (2) of the Clean Air Act, is charged (among other things) with

 independent scientific review of EPA's air quality criteria. 

The first and second drafts of the PM ISA were released on December 22, 2008 and

 July 31, 2009, respectively, for independent external peer review and public

 comment. These drafts were reviewed at public meetings of the CASAC PM Review

 Panel on April 1-2, 2009 and October 5-6, 2009, respectively. This final PM ISA has

 benefited from the expert comments received at the CASAC meetings and from

 public comments, and it has been revised accordingly.
