the Study Area, however as much as possible the site will be covered in gravel
or an equivalent porous material.
Diesel will be stored on site during operation for the black start diesel units
and constitutes a potential impact if there are any resulting spills. Incorrect
waste disposal may also result in potential soil contamination.
Impact Significance
The negative impacts on soil will be long-term, for the lifetime of the project
and are local, restricted to the site and adjacent areas. The impact magnitude
is therefore considered to be minor.
Given the low sensitivity of the surrounding areas, which are already
disturbed, the resulting impacts are considered to be minor prior to
mitigation. Furthermore it should be ensured that to the extent possible the
site is covered with gravel or equivalent materials to ensure that the impacts
on run-off are kept to a minimum.
7.5.3 Impact Description and Significance: Decommissioning
Impact Description
It is assumed that decommissioning will involve removal of the plant and
equipment and restoration of the site. It is possible that the site will be
redeveloped for other industrial use, depending on the situation at the time of
the end of the Project’s life. For this assessment it is assumed that the
decommissioning activities will include dismantling and demolition of Project
facilities as well as subsequent earthworks and site levelling. Since certain
areas of the site are likely to be covered with hard standing, this would be
removed. The resulting disturbance and associated soil compaction could
result in negative impacts such as increased erosion. Improper handling of
the waste generated during decommissioning from the dismantling and
demolition activities could result in contamination of soils. After
decommissioning, the soil profile will be allowed to be re-established through
artificial means and through colonisation by plants.
Impact Significance
The impacts on soil during decommissioning will be local and temporary and
the magnitude is therefore considered to be low. The soil on the Project site
will have already been modified and disturbed to a large degree once the
decommissioning phase of the Project occurs and the receptor is therefore
considered to be low.
The overall significance of the impacts on soils during decommissioning are
minor prior to mitigation.
