for the project. Shift changes times and the method of moving product between the mine and Camden Power
Station plays a major role in the trip generation. In this instance the mine is and existing operation with trucks
delivering coal to Camden Power Station. This will continue with between 120 and 150 thirty ton truckloads per
day for 24 hour operations.
12.10 Land capability assessment
The soils vary somewhat in physical and chemical composition over the different areas, are strongly influenced
by the parent materials (geology) from which they are derived, as well as by their position in the topography and
the origin of the soils (in-situ versus colluvial derived).
The major soil forms that occur on the proposed development are as follow:
On the crests and mid-slopes the typical catena is Glencoe soils followed by Avalon soils on the lower mid- and
foot-slopes and then Westleigh, Longlands, Katspruit and Rensburg soils associated with wetlands.
Glencoe (Gc)
The Glencoe soils have an Orthic A Horizon over a Yellow Brown Apedal B Horizon over Hard Plinthite. The
average depth of the Glencoe soils range from 30-60cm on the crests to 60-90cm on the mid-slopes. Subdominant
to Glencoe soils are Clovelly soils and shallow Dresden with hard rock and/or hard plinthite in the sub
soil.
RECOMMENDATION: Suitable for irrigation development. Good irrigation/water management needed. The
soils shallower then 40cm is suitable for grazing only.
Avalon (Av)
The Avalon soils have an Orthic A Horizon over a Yellow Brown Apedal B Horizon over Soft Plinthite. The
average depth of the Avalon soils Glencoe soils range from 60-90cm on the mid- and foot-slopes. Sub-dominant
to Avalon soils are Longlands soils on the foot-slopes.
RECOMMENDATION: Cultivation of dry land agriculture is possible. Under irrigation these soils become wetter
for prolonged periods, giving rise to a rise in the water table, and occasional waterlogged conditions develop for
extended periods if not well managed (drainage installed).
Westleigh (We)
The Westleigh soil has an Orthic A Horizon over a soft Plinthic B horizon with some signs of wetness in the subsoil.
The depth ranges from 0—60cm depending on the wetness of the soil. Sub dominant to the Westleigh soils
are Longlands, Katspruit and Rensburg soils forms.
The abovementioned soils forms are by definition soils with hydromorphic characteristics and all associated with
wetland conditions.
RECOMMENDATION: Unsuitable for irrigation. It is marginal for dry land crop production due to position in the
landscape. These soils should not be disturbed and are classified as wetland soils.
