II. Short term aspects mainly centred on maintaining desired ambient air qualities. This will
bring us to the debate emission levels. The ground level dispersion of emission components are easily
met far below existing standards by the modern 4-stroke diesel engines while burning heavy fuel.
In view of the above, adequate chimney/stack heights for guiding the exhaust gases away from
the ground level can easily ensure low dispersions at ground level after emission at relevant designed
chimney heights based on sulphur contents in the fuel
