3.2 View from Graceland Casino At present the degree of visibility of the landfill from the Graceland Casino grounds is limited, due to the presence of existing trees located in the area in between.

The visual impact is also further reduced due to the distance between the landfill and the casino and as a result, only the western half of the landfill is exposed to view.

However the visibility of the landfill increases significantly when its height is increased, due to the fact that the Casino is located in a slightly elevated position in relation to the landfill. This occurrence will be more pronounced when viewed from the higher storeys of the casino hotel, as viewers would effectively look over the existing vegetation onto the landfill. While the existing vegetation still offers some degree of screening at a height of 5 m and 10 m, more than half of the facing landfill side slope will be visible at a height of 15 m and especially at 20 m.

By establishing a tree screen along the western half of the northern site boundary, the landfill can still be significantly screened from view at a landfill height of 5 m. This is no longer the case at a landfill height of 10 m as the upper half of the landfill is now visible above the existing trees in the left hand half of the view and also protrudes above the tree screen. The level of visibility of the landfill is especially higher at heights of 15 m and 20 m, as the tree screen is no longer expected to obscure the top half of the landfill. However, the distance between the landfill and the casino is expected to mitigate the visual impact to some extent, especially once the landfill has been re-profiled and vegetated. In addition, the landfill will effectively screen much of the Sasol infrastructure behind it as its heights increases.

These aspects are illustrated by Figure 3.

3.3 View from Secunda Mall shopping Centre Similar to the Charlie 1 Gate, the visual impact of the landfill is at present significantly mitigated by the distance between the two areas and the presence of significant existing vegetation. In addition, the backdrop of the existing Sasol plant infrastructure and ash dams result in the landfill site not being visually intrusive.

This remains to be the case when the landfill is expanded to a height of 5 m, as the existing visual horizon backdrop or silhouette presented by Sasol is still “higher” than that of the landfill, effectively masking the landfill from view. By establishing a tree screen along the northern and eastern site boundary, the landfill is effectively completely screened from view. At a height of 10 m the topmost part of the dump protrudes above the tree screen but is still not expected to be visually prominent as it will likely be overshadowed by the infrastructure behind it.

Whilst the level of visibility of the landfill increases more significantly with a height increases to 15 m and 20 m, the resultant visual impact is still largely mitigated for the same reasons as stated above. The landfill is also not expected to significantly screen any of the existing Sasol infrastructure, at least not from elevated positions along the upper levels of the mall complex.

The above options are illustrated on Figure 4.

4.0 DISCUSSION AND RECOMMENDATIONS Based on the findings of the visual modelling conducted the most sensitive visual receptor is expected to be Charlie 1 Gate, as it is located directly adjacent to the existing landfill and hence has the highest visual exposure to the proposed landfill expansion. However, it is expected that the visual impact can be significantly mitigated by planting a tree and shrub screen along the perimeter of the site, regardless of the final height of the landfill.

Conversely, the extent to which the landfill can be screened is somewhat limited from the other receptor locations, as in most instances the viewer will be able to see over a vegetative screen than is planted alongside the landfill, especially at a final height of 15 m or 20 m. However, the severity of the visual impact is reduced due to the distance between the landfill and these receptor locations; and is expected to be further mitigated once the landfill has been re-profiled and vegetated. In addition, the landfill will in some instances actually serve to screen parts of the Sasol complex from view. Given the above considerations, from a visual perspective a final height of up to 10 m is likely to be considered unobtrusive as the impact can be largely mitigated from Charlie 1 Gate; and is not expected to be especially significant from the other main receptors which are located some distance away.

In terms of plant species, poplar (Populus nigra) and Plumbago auriculata were used as screening tree and shrub species respectively, as both species are expected to grow in the local climate. A number of other species may also be suitable for this purpose, which will influence the degree of visual screening provided as well as overall appearance of the resultant scenery. However, suitable non-invasive tree species choices are limited as few relatively fast-growing species would be suited to the climate. Another tree species that may be considered is the Fever tree (Acacia xanthophloea), while additional shrub species could include Ehretia rigida and Buddleja salviifolia. It is recommended that a botanist be consulted to provide further guidance in this regard.

Furthermore it is recommended that Sasol further engage with potentially affected stakeholders regarding the expansion of Charlie 1 landfill, to ensure that potential dissatisfaction or tension in this regard is avoided.

5.0 ASSUMPTIONS AND QUALIFICATIONS The following assumptions and qualifications apply to the visual assessment and resultant findings:

Only fully mitigated options are presented i.e. assuming the landfill has been re-shaped, capped and vegetated and all vegetative screens have been fully established, as opposed to an operational situation, which will likely be visually less favourable;

The modelled options assumed that all screening vegetation will be planted at commencement of landfill expansion, in order to afford sufficient time for plants to grow. The degree of visual screening will be compromised if screening vegetation is only planted towards end of operations;

The visual assessment assumed that optimal growth of plant species as well as re-vegetation of the landfill itself will have taken place. Poor plant growth as a result of unfavourable conditions or inadequate maintenance or other unforeseen occurrences were not taken into consideration, and will compromise the degree of screening as well as visual quality of resultant scenery;

The images represented in this document are significantly reduced in scale and therefore likely “underplay” the likely actual appearance and resultant visual impact of the expanded landfill. Images at appropriate scale are therefore separately provided on an accompanying DVD, and should be printed to A2 paper size to provide reasonable representation of expected effects; and

The results of this visual assessment process are based on conceptual/preliminary landfill designs and screening vegetation placement arrangements; and should therefore be considered as indicative only in the event of notable landfill configuration changes with detailed design.
