This briefing, sent by Eskom to the Department of Environmental Affairs (DEA) on 17 July 2014, provides additional information to support Eskom's application to postpone compliance with Minimum Emission Standards (MES) for the Duvha Power Station. The document focuses on ambient air quality monitoring data from three stations—Komati, Middelburg, and Witbank—and references an Atmospheric Impact Report regarding health and environmental assessments.

• At the Komati monitoring station, PM10 concentrations significantly exceed South African Ambient Air Quality Standards, with 82 to 162 exceedances of the 24-hour limit value recorded annually, compared to a permitted limit of 4. PM10 levels are higher in winter than in summer.
• The Komati monitoring station is in compliance with ambient SO2 and NO2 standards. NO2 levels remained below the 1-hour limit value with no exceedances recorded between 2010 and 2012.
• The Middelburg monitoring station shows non-compliance with PM10 standards, recording 68 exceedances of the 24-hour limit value in 2011 and 85 in 2012, against an allowed limit of 4 per year. Most exceedances occur between May and August.
• Middelburg is in compliance with ambient SO2 and NO2 standards. No 24-hour average SO2 limit exceedances were recorded in 2011 or 2012, and only three 1-hour limit exceedances occurred in 2011.
• The Witbank monitoring station is in non-compliance with both SO2 and PM10 standards. For SO2, 31 exceedances of the 24-hour average limit were recorded in 2011 and 16 in 2012 (limit is 4). For PM10, 57 exceedances of the 24-hour limit occurred in 2011 and 50 in 2012 (limit is 4).
• Witbank is in compliance with ambient NO2 standards, with no 1-hour limit value exceedances recorded in 2011 or 2012.
• Eskom directs the DEA to the Atmospheric Impact Report (Annexure C) for data on residential area positions (via isopleth plots), human health impact analysis (Section 5.6), and environmental impact analysis (Section 5.7).
