NOTE: THIS DOCUMENT IS A PRELIMINARY DRAFT. It has not been formally released by the U.S. Environmental Protection Agency and should not at this stage be construed to represent Agency policy or factual conclusions. This document is being provided now for review to EPA's Science Advisory Board. It should not be cited or referred to as EPA's final National-Scale Air Toxics Assessment.
This is a 205 page draft document (2 MB) on EPA's National-Scale Air Toxics Assessment that looks at nationwide inhalation risks from outdoor emissions of 33 pollutants (33 air toxics plus diesel particulate). EPA is soliciting the views of the Agency's Science Advisory Board through peer review before finalizing the results and before drawing conclusions about the relative risks of the air toxics examined in this assessment. The purpose of this national-scale assessment is to characterize the cancer risks and noncancer health effects of these air toxics on a broad scale to help identify pollutants of greatest potential concern to the greatest number of people. This will help set priorities for the collection of additional air toxics data to improve future assessments. Due to the broad scale of the approach, it is not designed to characterize risks sufficiently for regulatory action or to identify risks at a local or neighborhood scale. The national-scale assessment is just one of several approaches EPA uses to evaluate air toxics. The results are most meaningful when viewed at the state or national level; for smaller areas, the assessment becomes less certain. For analysis of air toxics in these smaller areas, EPA relies on other tools such as monitoring and local-scale assessments to evaluate potential "hot spots" using more refined and localized data.
