This briefing, sent by Eskom to the South African Department of Environmental Affairs on 17 July 2014, provides additional information regarding an application to postpone compliance with Minimum Emission Standards (MES) for the Tutuka Power Station. It outlines planned retrofits for particulate matter and nitrogen oxides, discusses ambient air quality monitoring data from the Grootdraai and Majuba stations, and addresses data gaps regarding PM2.5 health and environmental impacts.

• Eskom intends to install fabric filter plants (FFPs) and low NOx Burners (LNBs) at Tutuka Power Station, with completion dates set for April 2024 and April 2025 respectively. These retrofits are intended to bring the station into compliance with the 2020 'new plant' MES for particulate matter (PM) and nitrogen oxides (NOx). However, Eskom stated it has no plans to upgrade the station to meet the new plant SO2 emission limit.
• Eskom argues that full compliance with the MES by the 2015 and 2020 deadlines is not beneficial or practically feasible for South Africa, leading the company to propose a phased and prioritised approach to compliance.
• Monitoring at the Grootdraai station showed compliance with ambient SO2 standards, with no 24-hour limit exceedances in 2010 and 2011, and 2 exceedances in 2012. Hourly SO2 limit exceedances were 2 in 2010, 13 in 2011, and 36 in 2012, all within the allowed frequency of 88 per annum. Ambient NOx values were generally well below limits, with 5 exceedances of the 1-hour limit in 2012 and none in 2010 or 2011.
• Air quality data for particulate matter (PM10) at the Grootdraai monitoring site is described as having poor availability and questionable quality, though indications suggest non-compliance with ambient PM10 standards.
• At the Majuba monitoring station, ambient SO2 and NOx standards were met, despite 1-hour limit exceedances occurring in most years. PM10 levels showed compliance in 2010 but non-compliance in 2012, although data availability for 2011 was poor for both NOx and PM10.
• Eskom reports a lack of sufficient information on particle size distribution to model the specific impact of PM2.5 emissions from Tutuka Power Station. Consequently, Eskom used PM10 concentrations from the Majuba Power Station for its Atmospheric Impact Report. Eskom suggests that while there is a risk of non-compliance with ambient PM2.5 standards, Tutuka's emissions make only a small contribution to total ambient particulate levels.
