Impact/Purpose:
This report provides critical evaluation and integration of the evidence on health and environmental effects of ozone to support EPA's Office of Air with the review of the NAAQS for ozone.
Description:
The Integrated Science Assessment for Ozone and Related Photochemical Oxidants document is a concise synthesis and evaluation of the most policy-relevant science, and has been prepared as part of the review of the primary (health-based) and secondary (welfare-based) National Ambient Air Quality Standards (NAAQS) for Ozone under the Clean Air Act. When final, the Ozone ISA, in conjunction with additional technical and policy assessments, will provide the scientific basis for EPA's decision on whether the current primary and secondary air quality standards for Ozone sufficiently protects public health and welfare.
