Description of the source (including control equipment). Please see the attachments for source or

 process flow diagram:

One (1) dry bottom, pulverized coal-fired boiler, identified as Unit No. 1, constructed in

1974, with a start up date of 1979, with a design fuel heat input capacity of 2518 million

(MM) Btu per hour (nominal HHV), with a fabric filter for control of particulate matter (PM),

with a dual alkali flue gas desulfurization (FGD) system for control of sulfur dioxide (SO2),

with low-nitrogen oxides (NOx) combustion (low-excess air and low -NOx burners) and

selective catalytic reduction (SCR) system for control of NOx, with continuous emissions

monitoring systems (CEMS) for NOx and SO2 and continuous opacity monitoring (COM)

system for opacity and exhausting to stack #1. Natural gas (NG) can be used as an

alternate fuel for startup, shutdown, and malfunctions.
