PERFORMANCE
Feedback on our Sulphur Dioxide
(SO2) application to be regulated on
a alternative load-based emission
limits under Clause 12A of our MES
We previously reported that Sasol sought a
dispensation in terms of Clause 12A of the
Listed Activities and Associated Minimum
Emission Standards 2013, promulgated under the
National Environmental Management: Air Quality
Act, 39 of 2004, for its Secunda Operations to
be regulated under alternative load-based
emissions standards from 1 April 2025 onwards.
The application was initially declined by the NAQO
and Sasol subsequently filed an appeal to the
Minister of Forestry, Fisheries and the
Environment in July 2023.
On 5 April 2024, the Minister issued her decision,
in terms of which she upheld Sasol’s appeal
and set aside the decision of the NAQO.
The Minister concluded that Sasol’s application
met all the requirements of Clause 12A, and
therefore replaced the NAQO’s decision by
permitting that load-based limits be applied
from 1 April 2025 up to 31 March 2030, subject to
further conditions. The decision was contingent
on the Minister’s subsequent determination of
concentration-based limits to apply, in addition
to the load-based limit. On 26 July 2024, Sasol
received notification that the concentrationbased limits have been determined and Sasol
can accordingly continue with the
implementation of its load-based integrated
solution. Sasol will apply to the local licensing
authority to incorporate the abovementioned
limits in the atmospheric emissions license (AEL)
for its SO to give effect to the Minister’s
decisions. The varied AEL will enable lawful
operations from 1 April 2025.

Air quality abatement achievements
Air quality performance
Atmospheric emissions
kilotons (kt)
Particulate Matter (PM)
In FY24, we have achieved the following:
2024
2023
7,55
7,63
Reasons
SO: 0,5% reduction associated with additional
Electro Static Precipitators (ESPs).
SEO: 6% reduction associated with boiler
retrofits.
Nitrous Oxides (NOx)
114,04
122,04
SO: 7% reduction overall, associated with the
retrofit of additional low-NOX burners at our
South African operations.
Sulphur Oxides (SOx)
160,87
166,88
SO: 9% decrease predominantly due to better
coal quality into our boiler operation.
Air quality offsetting programme
We are committed to the second phase of our offsetting implementation plan, which is
focused on the reduction of PM and SO2 emissions in surrounding communities.
For FY24 the plan included the following initiatives:
• a comprehensive education and awareness campaign, covering nine schools and the public;
• paving of an additional 1,8 km road to reduce dust pollution;
• retrofitting of household thermal insulation and the swop out of coal- for LPG- stoves in
5 532 homes in the eMbalenhle and Lebohang communities;
• the rollout of low-smoke coal stoves to households in the Zamdela area to reduce emissions
from conventional stoves; and
• re-establishing the vehicle emission testing programme that commenced in May 2024.
Air quality abatement achievement towards 2025
We are on track with implementing our air quality roadmaps, aiming to achieve compliance
with the new plant standards in 2025. We continue to engage with the National Air quality
officer on our progress and associated challenges.

PM emission reduction
Improvements for PM reduction within Secunda,
Sasolburg and Natref Operations include:
• at SO, we retrofitted 16 out of 17 ESPs
with abatement equipment;
• at SEO’s Steam Station plants, we upgraded
eight of the 12 ESPs with one boiler being
retrofitted at our Steam Station 1 plant.
NOx emission reduction
At SO, in FY24 we completed the retrofit of
three more boilers with low NOx burner
abatement technology, bringing the total
retrofitted so far to nine. At year-end, a fourth
installation was underway and a retrofit of the
rest of the fleet was on track to be fully
compliant with the MES limit.
At SEO, low NOx burners were also installed
on seven of the 12 operational boilers.
Incinerator emission reduction
At SO, we made progress on our biosludge-togasification project, with eight lysis reactors
installed by year-end. The project entails the
recycling of the biosludge waste stream into
a gasification feedstock, thereby allowing for the
decommissioning of the biosludge incinerators
and decreasing our on-site GHG emissions.
There is one incinerator online which is compliant
with emission standards at SEO, however, we
continue to review alternatives to incineration for
waste streams from Sasolburg.
