Based on a Federal Court decision the US EPA has agreed to propose the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating Units. This NESHAP is to be proposed by March 16, 2011 and promulgated by November 16th, 2011. This NESHAP, and the associated requirements for MACT (Maximum Achievable Control Technology), are expected to be very similar in form to the Industrial Boiler MACT. The MACT floor, based on EPA regulations, cannot be less stringent than the average emission limitation achieved by the best performing 12% of existing sources for subcategories with 30 or more sources, or the best-performing 5 sources for subcategories with fewer than 30 sources. Accordingly at least 90% of the Utility industry will be affected by the emission standards promulgated under this MACT. The MACT requirements will require upgrades and modifications to existing emissions control equipment and the installation of new control systems to limit emissions of mercury, the other criteria metals, acid gases such as HCl, and organics. This presentation will address the potential impacts on existing Utility Assets and discuss the implications and limitations of existing control technology to control the air pollutants addressed by this NESHAP.
