Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The Intermountain Power Project (IPP) consists of two 950 MWhe (gross) coal-fired thermal cycle steam-electric generating units. Each identical unit has a dry bottom boiler utilizing opposed wall low-NOX control burners with associated over-fire air for NOX reduction during combustion. Other pollution control devices (PCD) include fabric filter baghouses with reverse air cleaning and multi-module counterflow wet spray limestone flue gas desulfurization (FGD) scrubbers. Each IPP unit uses a continuous emissions monitoring system (CEMS) certified under both Part 75 for the Acid Rain Markets Program, and Part 60 New Source Performance Standard (NSPS) to monitor CO2, NOX, and SO2. Each unit also utilizes an uncertified mercury CEMS that measures flue gas concentrations only, since a data acquisition and handling system (DAHS) has not yet been integrated due to the remand of the Clean Air Mercury Rule (CAMR).
