Rehabilitation of overburden stockpile areas
After the removal of overburden material for backfilling of the final voids, the stockpile areas will be
ripped to 100mm and covered with a layer of topsoil. Sections used to access the areas will be ripped
to 250 mm before being covered with topsoil for seeding.
Rehabilitation of the pollution control dam and the diversion trenches/berms
The pollution control dam will be cleaned out and filled with stockpiled subsoil. A layer of topsoil will
be spread over the rehabilitated surface.
The clean and dirty water diversion trenches will be cleaned out and filled, after the rehabilitation of
the stockpiling area. Berms will be pushed into the trenches as filling material.
Seeding of rehabilitated areas
Following mechanical rehabilitation of the area, a seed mix will be applied to all rehabilitated areas to
accelerate vegetation establishment. The species to be used for seeding will be based on the
vegetation specialist recommendation.
Maintenance and monitoring of rehabilitated and surrounding environments
All rehabilitated areas will be monitored for cracks, erosion and settlements. All cracks, erosion
gullies and settlement depressions will be repaired.
Data gathered from the above maintenance and from a monitoring programme will be used for the
application of a closure certificate.

The tables below describe the assessment of impacts from the proposed mining operations, its
associated activities and the changes in the existing Nkomati Anthracite mining operations. Note that
under the assessment the following abbreviations i.e. E, P and S were used, which stands for Extent,
Probability and Significance respectively.
The assessment also shows the cost for the mitigation measures that has been properly budgeted for
by Nkomati Anthracite (Pty) Limited. The annual budget for Nkomati Anthracite (Pty) Limited showing
money put aside for the management of environmental impacts as determined under the impact
assessment is attached as Appendix 5.
