Regulatory Finding on the Emissions of Hazardous Air Pollutants From Electric Utility Steam Generating Units

Riepilogo

This notice presents EPA's finding required by section 112(n)(1)(A) of the Clean Air Act (CAA) as to whether regulation of emissions of hazardous air pollutants (HAP) from fossil fuel-fired electric utility steam generating units (as defined in section 112(a)(8) of the CAA) is appropriate and necessary. This finding is based on the results of EPA's February 1998 "Study of Hazardous Air Pollutant Emissions from Electric Utility Steam Generating Units--Final Report to Congress' (utility RTC), and on information obtained subsequent to the utility RTC concerning HAP emissions to the atmosphere from electric utility steam generating units. In the utility RTC, the EPA indicated that coal- and oil-fired electric utility steam generating units are significant emitters of HAP, including mercury which is emitted from coal-fired units, and which EPA identified as the HAP of greatest concern to public health from the industry. Based on the available information, the Administrator finds that regulation of HAP emissions from coal- and oil-fired electric utility steam generating units under section 112 of the CAA is appropriate and necessary. As a result, this notice adds coal-and oil-fired elect
