This report by the Northeast States for Coordinated Air Use Management (NESCAUM) dated November 2008 finds that ICI boilers are a significant source of NOx, SO2, and PM emissions, which contribute to the formation of ozone, fine particles, and regional haze, and to ecosystem acidification. These boilers are relatively uncontrolled compared to EGUs and offer the potential to achieve cost-effective reductions for all three pollutants. A host of proven emission control technologies for EGUs can be scaled-down and deployed in industrial, commercial, and institutional settings to cost-effectively reduce emissions of concern. Other technologies that have not been applied to EGUs show promise for ICI boiler applications. Careful analysis will be needed to match the appropriate emission control technology for specific applications given: boiler size, fuel type/quality, duty-cycle, and design characteristics. Further, regulators will need to determine
the level of emission reductions needed from this sector in order to inform the appropriate choice of controls.
