NOx emissions are

NOx emissions are considered to be baseline emissions. To define uncontrolled NOx emissions for the pre-NSPS boilers, emissions data from various databases and utility retrofit applications were examined. To define baseline NOx emissions for the subpart D and Da boilers, the NSPS limits as well as emissions data from various databases were examined. 2-4
