PM emission rates reflect existing ESP. PM control scenarios were modeled separately from SO2 and NOx controls with results showing that the visibility improvement is negligible.

NOx control scenario emission rates reflect application fo a 20% increase over the design emission rate to account for variability. NOx emission rates calculated at a heat input capacity of 6,015 

2

SO2 control scenario emission rates reflect application of a 70% increase over the design emission rate for new scrubber to account for variability. SO2 control scenario emission rates were 

calculated at maximum fuel sulfur content of 2.6 lb/MMBtu. Shown at an assumed heat input capacity of 6,015 lb/MMBtu.
