* DETAILED DESCRIPTION OF WASTE GENERATING PROCESS

Secunda Synfuels Operations Process: The sources of ash generated at Secunda Synfuels Operations are the Steam plant and Gasification plant where synthesis gas and steam are generated respectively.

Ash from the gasification process is made up of an 80 % coarse ash fraction, which is transported to the coarse ash heaps via conveyor belts, and a 20 % fine ash fraction which is transported to the fine ash dams in a slurry form by means of pumping.

Ash from the combustion process is made up of 86.4 % fine ash, which is transported to the fine ash dams together with the gasification fine ash fraction. The remaining 13.6% coarse ash is transported to the ash heaps together with the gasification coarse ash fraction.

The following factors and criteria must be used to assess the impacts of the activities:

Criteria MAGNITUDE (Severity) DURATION

10 - Very high 5 – Permanent (longer than 10 years) 8 – High 4 - Long-term (5 to 10 years) 6 – Moderate 3 - Medium-term (12 months to 5 years) 4 – Low 2 - Short-term (0 to 12 months) 2 – Minor 1 – Immediate

SCALE PROBABILITY (Likelihood) 5 – International 5 - Definite 4 – National 4 - Highly probable 3 – Regional 3 - Medium probability 2 – Local 2 - Low probability 1 - Site only 1 – Improbable 0 – None 0 – None

Magnitude Magnitude measures the size of the impact

Duration Duration refers to the lifetime of the impact i.e. how long it will last

Scale The scale refers to the extent of the impact.

Probability The probability refers to the chance of impact to occur. The potential impact could be most likely to occur, unlikely, etc. Assessment of Significance of impact Significance rating of the potential impacts illustrates the importance of the impact itself. The size of area affected by pollution may be extremely high but the significance of this effect is dependent on the concentration or level of pollution in that area. In order to determine the significance of impact, the following method was used: Significance Points (SP) = (Magnitude + Duration + Scale) x Probability The values of SP are then ranged as follows:

Rating Description

SP >60 Indicates high environmental significance

An impact which could influence the decision about whether or not to proceed with the activities regardless of any possible mitigation.

SP 30 – 60 Indicates moderate environmental significance

An impact or benefit which is sufficiently important to require management and which could have an influence on the decision unless it is mitigated.

SP <30 Indicates low environmental significance

Impacts with little real effect and which will not have an influence on or require modification of the activities.

+ Positive impact An impact that is likely to result in positive consequences/effects

RISK MANAGEMENT PLAN


Action(s) to minimise/ manage the risk Responsibility (Who is responsible to do it)



Preventative mitigation measure Dust management during loading of ash through

wetting of ash Stop loading of ash during extreme wind conditions

Ash generator i.e. Sasolburg Operations and Secunda Operations

Corrective mitigation measure Wearing of relevant PPE (dust mask and eye

protection) during ash loading

Ash generator employees Ash transporter employees



Preventative mitigation measure Dust management during transportation will include

ensuring vehicles follow an approved route that will limit the exposure of dust in communities.

Side tippers with tarpaulin devices will be recommended for the transportation of ash, however, those that cannot be covered will not be filled to capacity and will be required to go through a dust suppression (wetting) process.

Corrective mitigation measure None

Ash transporters

Preventative mitigation measure Compliance with the Road Traffic Act; Sasol Transport Policy and Procedures; Access to ash limited to customers and transporters

that have commercial contracts with Sasol. Corrective mitigation measure Implementation of the Emergency response plan; Use of Safety Data Sheet (SDS) with hazard

classification which is provided to all customers and transporters.

3. Off-loading of ash



wetting of ash Stop off-loading of ash during extreme wind

conditions Corrective mitigation measure Wearing of relevant PPE (dust mask and eye

protection) during ash off-loading

storing more than a 100 m3 of ash at a time, should have a firm impermeable surface on which to place the ash and a system to collect and store run-off arising from the ash storage facility.

Corrective mitigation measure The use of Safety Data Sheet (SDS) with hazard

classification which is provided to all ash users. Clean-up plan to be implemented where ash is

carried way from storage area 5. Handling of ash

Corrective mitigation measure Clean-up plan to be implemented where ash is not

disposed properly.

Ash users



Preventative mitigation measure Contractual agreement with ash customers to include

the following clause: "The owner of the facility, including the subsequent owner of the facility will remain responsible for any adverse impacts on the environment and health stemming from stockpiled ash, even after operations have ceased."
