100August 2010 8848Disposal Site, including Boipatong, Tshepiso, Sharpeville and Sebokeng. The VaalTriangle Airshed Priority Area – Air Quality Management Plan, identified domestic fuelburning as one of the main sources of particulate emissions within the region.• Biomass burning – major pollutants from veld fires are particulates, CO and VOCs. Theextent of Nox emissions depends on combustion temperatures, with minor sulphur oxidesbeing released.• Various miscellaneous fugitive dust sources, including: agricultural activities, winderosion of open areas, vehicle-entrainment of dust along paved and unpaved roads.The pollutants listed above are released directly by sources and are therefore termed‘primary pollutants’. ‘Secondary pollutants’ which form in the atmosphere as a result ofchemical transformations and reactions between various compounds include: NO2, variousphotochemical oxidants (e.g. ozone), hydrocarbon compounds, sulphur acid, sulphates,nitric acid and nitrate aerosols.Therefore, from the aforementioned the impact is of an existing HIGH significance that isoccurring the long term as a result of both the site and the industries in the area. Thereforethe initial impact is rated as a High impact.Additional ImpactOnly particulate impacts due to wind erosion on open surfaces, materials handling due toearthworks to shape the floor to an even grade and vehicle entrainment are predicted to berelated to construction phase. Possible air quality impacts associated with these emissionsare health risks associated with predicted inhalable particulate matter and nuisance impactsas a result of predicted dustfall levels. The impact is therefore rated as a low impact.Alternative 1 has been rated separately to alternative 2 and 3 as a result of the severity of nobuffer zone from the public and therefore an increase in the significance to adjacent landoccupiers. It is in the opinion of the specialist that Alternative 1 is not acceptable.Cumulative ImpactThe cumulative impact will remain as assessed for the initial impact, therefore a high impact.Mitigation MeasuresGiven the close proximity to residential areas and the exceedance of the general 500 mrecommended buffer zone, the following recommendations are made:• Dust suppression measures should be undertaken on a daily basis throughoutconstruction;ZITHOLELE CONSULTING
