conduct air quality modeling, and conduct risk assessments to understand how air pollution may affect the health in communities across the country. An example of EPA’s use of the NEI is that the data are used as one of the considerations in area designations for new or revised National Ambi...
data that suggest at least 21 states could face a Clean Air Act duty to curb transported emissions of ozone under the agency's latest strict ambient air limit for the criteria pollutant, including many of the states subject to the Cross-State Air Pollution Rule (CSAPR) emissions trading ...
Paulsboro High School - Valero refinery and Air Products chemical plant in background. Note the direction of plume from stack - pollution is being blown directly toward school. I could strongly smell volatile organic chemicals. After just 15 minutes shooting these pictures, I was nauseous and had...
A group of scientists assembled by the EPA to advise it on air pollution standards couldn't reach agreement on whether the standards should be tightened or remain the same, a development that may complicate ongoing effort to update them. The Environmental Protection Agency's Clean Air Scientific ...

The proposals mainly affect air emissions by old coal-fired power plants and would require the plants to meet emissions targets in 2010 and 2015. The proposals set national emission caps and allowutilities to meet them by pollution trading as well as by installing controls. The result would be...
(dv) based on a 90thpercentile form over three years. EPA also sought comment on alternative levels (down to 25 dv) and averaging times (e.g., 4 hours). Based on public comment and further analysis of air quality monitoring data, EPA concluded that the current secondary standard would ...

Hence, satellite data can be used to monitor global air pollution on an almost daily basis. In our current study we used seven years of surface and satellite data over several locations in EPA region 4 to derive these relationships. We also discuss the uncertainties associated with using ...
