6.8 Cumulative impacts<br />
Anthropogenic activities can result in numerous and complex effects on the natural and social<br />
environment. While many of these are direct and immediate, the environmental effects of individual<br />
activities (or projects) can combine and interact with other activities in time and space to cause<br />
incremental or aggregate effects. Effects from disparate activities may accumulate or interact to<br />
cause additional effects that may not be apparent when assessing the individual activities one at a<br />
time (Canadian Environmental Protection Agency, no date).<br />
The IFC Procedure for Environmental and Social Review of Projects (IFC, 1998) states that<br />
environmental assessment should include consideration of “… cumulative impacts of existing<br />
projects, the proposed project and anticipated future projects.” For the purposes of this report,<br />
cumulative impacts are defined as ‘direct and indirect impacts that act together with current or<br />
future potential impacts of other activities or proposed activities in the area/region that affect<br />
the same resources and/or receptors’.<br />
6.8.1 Cumulative impacts of existing activities<br />
It is reasonably straightforward to identify significant past and present projects and activities that may<br />
interact with the project to produce cumulative impacts, and in many respects, these are taken into<br />
account in the descriptions of the biophysical and socio-economic baseline.<br />
The main potential impacts of this project, though very limited, occur during the construction phase<br />
and affect water and habitats as well as employment and traffic. Existing activities that currently<br />
affect the above aspects, and which therefore determine the cumulative impact of all activities, are<br />
discussed in Sections 4.1 and 4.2.<br />
As most of the impacts associated with the pipelines are of very low or no significance, the pipelines<br />
project is not expected make a significant additional contribution to existing impacts on the<br />
biophysical and socio-economic resources in the study area.<br />
6.8.2 Potential cumulative impacts of future activities<br />
Relevant future projects that are included in the assessment are defined as being those that are<br />
‘reasonably foreseeable’, i.e. those that have a high probability of coming to pass in the foreseeable<br />
future; speculation is not sufficient reason for inclusion.<br />
For the most part, cumulative effects or aspects thereof are too uncertain to be quantifiable, mainly<br />
due to lack of (accurate) data. This is particularly true of cumulative effects arising from potential or<br />
future projects, the design or details of which may not be finalised or available and the direct and<br />
indirect impacts of which have not yet been assessed.<br />
In this particular case, however, one important future project that will determine cumulative impacts<br />
is the <strong>Staatsolie</strong> Refinery Expansion project, which the pipelines will service, and the potential<br />
expansion of the SPCS power plant. The refinery expansion is currently underway, and potential<br />
impacts of the project are well understood from the <strong>EIA</strong> that was undertaken for the project in<br />
2009/10.<br />
Generally, the following cumulative impacts were identified for the Refinery Expansion Project:<br />
• Further alteration of the landscape (visual quality and sense of place) and reinforcement of the<br />
long term trend to urbanisation;<br />
• Acceleration of the deterioration of ambient air quality in the vicinity of the refinery;<br />
• Increase in the ambient noise levels in the vicinity of the refinery site;<br />
