Bold and goldindicates where, for the No Subcategory option, the best performing unit has an incalculable limit, so the lowest calculable limit determined over all subcategories was selected. Blue, bold and highlighted indicates where a concentrations of zero were reported for the best performing unit. Therefore, to account for data variability, the lowest non-zero data from units in this subcategory was used. NOx (ppmvd)SO2
