Kendal Power station Ash Disposal Facility Project: Liner 3 years concession 21 February 2014 1
Kendal Power Station 2 2
Kendal Ash Project: Background • Kendal Power Station is a coal-fired power station situated south west of Ogies in the Mpumalanga province and falls within Emalahleni Local Municipality within Nkangala District Municipality. • The station is a Dry Ash Dump which was designed in the mid 1980’s for a 40 year station life, plus an 8 year contingency period. The expected station operating life has since been increased to 60 years till 2053 which will result in an increased amount of ash that would have to be disposed. The quality of the coal used is poor and contribute to more ash than anticipated. “This renders originally designed Ash Facility to be under capacity." • To avoid the ash management challenges, two process were established for extending the current ash disposal site (Continuous ash project) and acquire a new site for ash disposal (30 year ash project). • Both EIA processes for these projects are underway and at EIR phase. 21 February 2014 3 3

Challenges on the Continuous Ash Project • The current site ashing space is anticipated to be reached by August/September 2014 and the new area (referred to as continuous project) would have to be used. • Ash from electricity generation was excluded from waste ito ECA, so no waste management license was required, until the promulgation of NEMWA, 2008. So WUL was the driver for authorisations • Eskom need to ensure that all Environmental requirements are met before ashing on the new area/site hence the EIA process is underway to obtain a Waste Management License. • However according to planning processes readiness, the liner will not be placed on time for ashing onto new land due to the following: The long lead material process to acquire material needed for lining The preparation time required for lining Engineering detailed design which it prerequisite is in the EA, although the project has started undertaking acquisition process parallel to the process. The required time for undertaking EIA/WULA processes for acquiring of EA/WUL 21 February 2014 5 5

Kendal Ash Dump – Current Schedule 7 7
Current controls • Kendal Power Station is committed to ensure that all its operations comply with all relevant legislations and its policies and procedures. • In order to achieve the duty of care principles and reduce the ash dump footprint, the followings are been considered: The feasibility study to piggyback (ashing) on the existing ash disposal site while EA is acquired and the site is prepared for liner. This study is not yet concluded and therefore its feasibility not known currently Engagement with DWA to motivate for the 3 years concession while the project prepares the liner requirements. 21 February 2014 8 8
Conclusion and recommendation • As Kendal uses coal to generate electricity, it is unavoidable to have ash. This results in a huge need for the ashing land/space. Should piggyback feasibility not prove to be feasible and 3 years concession proposal not be supported by DWA, the station will be forced to stop ashing which means stop operation. And this will negatively affect the country’s economy. Proposed recommendation: • Request for DWA’s intervention to support the proposal of 3 years concession till 2017 while the lining preparations are put in place. 21 February 2014 9 9
