Kendal Ash Project: Background

• Kendal Power Station is a coal-fired power station situated south west
• f 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.

Kendal Ash Dump Remaining Standby Shifts Inside Fence (Continuous Ashing)

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

Kendal Ash Dump – Current Schedule

8

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.

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.
