HIGHVELD PRIORITY AREA
Based on the Minister’s reasonable belief that the eastern portion of Gauteng and the western portion of Mpumalanga province represented an area that was exceeding ambient air quality standards, the Minister declared this area as the “Highveld Priority Area” in terms of Section 18 of the National Environmental Management: Air Quality Act, 2004 (No. 39 of 2004, “the AQA”) on 23 November 2007.
In response to the Minister’s declaration, and in line with the requirements of the AQA in this regard, the department immediately initiated the development of an air quality monitoring network for the area as well as the participatory development of the required air quality management plan for the Highveld priority Area.
To this end –
-
5 high-tech monitoring stations were established in the Priority Area – the so-called Highveld Priority Area Air Quality Monitoring Network;
-
Professional consultants were employed to assist the department in the development of the required plan;
-
The Highveld Priority Area Air Quality Officer’s Forum (AQOF) was established to ensure efficient and effective intergovernmental coordination in the development of the required plan; and
-
The Highveld Priority Area Multi-Stakeholder Reference Group (MSRG) made of representatives of all interested and affected parties was established to ensure the fully participatory development of the required plan.
The following table provides a summary of the Highveld Priority Area Air Quality Management Plan development process to date –

Air Quality Problems in the Highveld Priority Area
One of the initial activities which informed the Highveld Air Quality Management Plan (AQMP) development process was the Baseline Assessment study. This study provided the status-quo of air quality in this priority area. The major findings from the Baseline Assessment study are summarised as follows:
Most of the HPA experiences relatively good air quality, but there are nine extensive areas where ambient air quality standards for sulphur dioxide (SO2), particulate matter with a diameter of 10 micrometers or less (PM10) and ozone (O3) concentrations are exceeded. The air quality hotspots result mostly from a combination of emissions from the different industrial sectors and residential fuel burning, with motor vehicle emissions, mining and cross-boundary transport of pollutants into the HPA adding to the base loading.
Existing monitoring confirms that the areas of concern are in the vicinity of Witbank, Middelburg, Secunda, Ermelo, Standerton, Balfour, and Komati where exceedances of ambient SO2 and PM10 air quality standards occur. The effects of poor dispersion conditions in the winter are evident throughout the monitoring record for all pollutants, resulting in greater frequency of exceedances of the standards. PM10 displays this seasonal trend most strikingly, showing a sharp contrast between wintertime peaks and summer minimum values at monitoring sites. Seasonal trends are clearly observed for O3 in the monitoring record, as springtime peaks are easily identified. Monitoring data show carbon monoxide (CO) and benzene to be within acceptable limits at the new sites. Trends in pollutant concentrations, based on current data, cannot be conclusively identified, marred in particular by poor data collection.
-
The total annual emissions of fine particulate matter (PM10) on the HPA is estimated at 279 630 tons, of which approximately half is attributed to dust entrainment on mine haul roads. The emission of PM10 from the primary metallurgical industry accounts for 17% of the total emission, with 12% of the total from power generation. By contrast, power generation contributes 73% of the total estimated oxides of nitrogen (NOx) emission of 978 781 tons per annum and 82% of the total estimated SO2 emission of 1 622 233 tons per annum.
-
Industrial sources in total are by far the largest contributors of emissions in the HPA, accounting for 89% of PM10, 90% of NOx and 99% of SO2.
-
One of the major contributors to air pollution, particularly in urban areas, is motor vehicle emissions, including NOx, CO, PM10 and volatile organic compounds (VOCs), including benzene (C6H6).
-
Using MODIS 500 m fire scar data and the SA National Land Cover Atlas (2000), an advanced biomass burning emissions inventory based on “burnt land cover” was developed and used to estimate annual emissions from biomass fires on HPA in kilotonne/annum.
Identified Hotspot Zones
Based on the outcome of the Baseline Assessment study, six priority areas where intervention strategies will take priority were identified, based on the predicted ambient air concentrations from the priority pollutants and exposure potential. The nine hotspot areas are Emalahleni, Kriel, Steve Tshwete, Ermelo, Secunda, Ekurhuleni, Lekwa, Balfour and Delmas.
Industrial Intervention Strategies
In terms of section 5.2 of the Plan, industries were requested to submit detailed emission reduction strategies with written approval by their management or activities already under implementation during 2010. About 16 industries responded positively and interventions will be incorporated into the draft plan as annexure, to be unpacked and populated into the template for the final HPA AQMP. The template comprises among others, emission reduction interventions, full descriptions of emission interventions, compliance date, estimated costs where possible and progress. Atmospheric Emission License numbers will also be attached to the interventions in the final plan. These will be used as a tool to measure progress towards the overall objective of reducing emissions in this priority area beyond national standards.
The next steps
Section 57(1) of the AQA requires the Minister to give notice of the proposed Plan - (a) in the Gazette; and (b) in at least one newspaper distributed nationally or, in at least one newspaper distributed in the Highveld Priority Area. In accordance with Section 57(2) of the AQA, the notice described above must - (a) invite members of the public to submit written representations on or objections to the proposed Plan to you within 30 days of publication of the notice in the Gazette; and (b) contain sufficient information to enable members of the public to submit meaningful representations or objections.
In terms of Section 57(3) of the AQA, the MInister may in appropriate circumstances allow any interested person or community to present oral representations or objections to the draft, or a person designated by the Minister. In terms of Section 57(4), the Minister must give due consideration to all representations or objections received or presented before finalising the Highveld Priority Area Air Quality Management Plan.
With this in mind, the department is satisfied that the process of developing the draft Highveld Priority Area Air Quality Management Plan has resulted in a plan of suitable quality for publication for public comment. The draft HPA AQMP and the executive summary have now been finalised for the MInister's approval and are ready for publication in the gazette for public comment for a period of 60 days. Only the executive summary will be published in the gazette, with reference to the comprehensive draft plan (with industrial interventions as annexure) on the South African Air Quality Information System.
The draft HPA AQMP will be published in the National Gazette before the end of April 2011.
