The dispersion modelling completed for the air quality assessment included the
following key aspects:
•
selection of dispersion modelling receptors;
•
conversion of predicted NO
X
concentrations to NO
2
concentrations
using the Ozone Limited Method (OLM); and
•
use of two years of meteorological data from the on-site meteorological
station located at the mine exploration camp.
A detailed description of the air dispersion modelling methodology is presented
in Volume I, Appendix 4.2.
3.4.3.1 Assessment Criteria
Madagascar does not have ambient air quality criteria; therefore, World Bank and
World Health Organization (WHO) guidelines were used. The World Bank
provides guidelines for SO
