Residual Risk Assessments


To assess the health risks imposed by sources of air toxics emissions, on a source category basis, to determine if control technology standards previously established for that source category are adequately protecting public health.


Each source category previously subjected to a technology-based standard will be examined to determine if health or ecological risks are significant enough to warrant further regulation. These assesments utilize existing models and data bases to examine the multi-media and multi-pollutant impacts of air toxics emissions on human health and the environment. Details on the assessment process and methodologies can be found in EPA's Residual Risk Report to Congress issued in March of 1999 (see web site).
