Ensure that the boiler stack height is 15m+ (as assumed in emissions modeling).
Use low sulphur fuels if monitoring identifies any stack or ambient concentration exceedances for SO2.
Ensure that all significant sour gas streams are routed to the sulphur recovery unit as planned and do
not combust in furnaces, boilers or flares.
Install low NOX burners when burner sets are replaced in existing plant.
Consider the installation of multi-cyclones, fabric filters or scrubbers to control soot emissions or
alternative technologies requiring less soot blowing. Alternatively, restrict soot blowing to periods of
good dispersion potential.
Use liquefied petroleum gas (LPG) and refinery fuel gas (RFG) firing, and distillate oil for start-up. Fuel oil
should only be fired if RFG supply is inadequate.
Implement an initial air quality monitoring campaign to compare modelled predictions against
measured data.
Schedule noise-generating construction activities, in particular piling activities, during business hours to
avoid after hours noise impacts.
Ensure adequate maintenance of construction vehicles and machinery to minimise excessive noise
generation.
Investigate and respond to complaints about excessive noise.
Establish land zoning in the wider area around the refinery especially for the areas to the south of the
expanded refinery (in cooperation with the local authorities) for the establishment of an industrial area
in which residential activities (and other sensitive receptors such as schools and hospitals) will not be
allowed.
Consider the establishment of a natural acoustic shield by planting or encouraging the growth of dense
trees and underbrush in the green belt around the refinery site, concentrating on the area to the south
of the refinery site.
Schedule noise-generating activities that are unrelated to the continuous operation of the refinery, e.g.
repairs/maintenance, loading/unloading of materials, etc., during business hours.
Implement a noise monitoring programme to validate the noise impact assessment and identify any
unforeseen noise issues.
Implement good management practices during the construction phase.
Restrict the footprint of construction activities and vehicle movements, including laydown areas.
