According to data on EPA's Clean Air Markets web page, Harrison's three boilers had NOx emissions rates of 0.298 to 0.349 lb/MMBTU. Pleasants Unit 2 was at 0.38 and the other Pleasants units are not far behind All have Low NOx boilers and SCR. This compares to rates in the neighborhood of 0.07 for Longview and 0.1 or less for the John Amos plant. As far as I can tell, Fort Martin has Low-NOx boilers but NOT SCR and its emission rates are lower than Harrison.
It looks to me like FirstEnergy could be doing better.

I had seen a news item about that petition last month (Deleware argues that the Harrison Power plant contributes to their air quality violations) but had trouble understanding why Deleware could be so specific about one plant that already has low-NOx boilers and SCR. This news article indicates that Harrison frequently operates without using the SCR, which would dramatically increase NOx emissions and down-wind ozone.
This could exacerbate the costs of operating Harrison, at a time when it is already under fire for costing more to operate than FE had projected.
Anybody know if this has a bearing on Pleasants?
