of ash per load. • Ash is dropped at disposal area and leveled to a depth of about half a meter (18-24 in). • Ash grading takes about 8 min with grader moving at 2.2 m s-1 (5 mph). • Fugitive emissions are primarily due to dropping and grading operations (haul trucks moving over bottom ash road produces very little fugitive dust).

Ash handling system are generally divided into three types fly ash handling system, bottom ash handling system and ash slurry disposal system. Fly ash handling system: Fly ash is captured and removed from the flue gases by economiser, air-preheater and electrostatic precipitator (ESP) located at the outlet of the furnace and before the induced draft.

Moisture content had a substantial role in PRB coal dust emissions; emissions dropped by two orders of magnitude as coal moisture content increased from 21 to 33%. Power plant sites with PRB coal that experience significant precipitation over a year would likely overestimate fugitive coal dust emissions if using AP-42,
