6.3.5 MUSIC Modelling Results
Refer to Figure 6.1 for a print screen schematic of the pre development MUSIC model and the
annual pollutant loads that will be discharged from the proposed development site. Refer to Figure
6.2 for a print screen schematic of the post development MUSIC model and the annual pollutant
loads that will be discharged from the proposed development site.
