Control scenarios for industrial sources can be considered for
rational air quality management for the industrial region. In this
study, two types of control scenarios have been made based on
increment of height of stack and fuel change. The first type of
scenario considers 10%, 25% and 50% increment of stack height and
second type of scenario considers change from high emission fuel
to low emission fuel. More height decreases ground level concentration
but it may cause regional impact on climate. Taller stack
needs larger area than shorter stack on the ground. The making
taller stack has more cost and risk. So, the control scenario based on
changing of fuel was taken. The SO2, NOx and PM emissions in
Chembur region are mainly from industries but emission change
strategies are available only for NOx and PM not for SO2. Thus,
emission based control strategies have been applied for NOx and
PM and increment of stack height has been applied for these all
three pollutants.
