The impact is considered to have a high significant impact as a result of the operational phase of the proposed
development with regard to the increase in traffic at the intersections with the N2. Mitigation measures reduce
the impact to a medium - low significance. Mitigation measures have been set out in the Environmental
Management Programme. The impacts will become more pronounced if the suggested mitigation measures are
not implemented.
Mitigation
Proposal A
• Access to the Power Station and the Mine is relocated to the new position and a second access is
implemented for Block D. An auxillary lane is provided on the N2 to accommodate the 150 x 30 ton
truck loads to the Power Station per day. From a traffic flow point of view the trucks will use the N2 from
Block D to the power station and back. When crossing the road, mining trucks will use the new access
and will experience increasing delays to cross the N2. Truck driver frustration and conflict with traffic on
the N2 will become an issue.
Proposal B
• The truck hauling takes place on the mine side, off the N2, and no additional access is implemented for
Block D. Coal is transported to the power station through a single access point on the N2. Operating
hours are amended to outside peak traffic hours and transport is supplemented by re-activating the
existing conveyor system between the mine and Camden Power Station. The ideal situation will be
reached at a point where only the conveyor system is used, with no coal trucks crossing the N2. This
will limit the impact on the N2 to only the intersection used by the mine and the power station. For this
proposal no additional cost is required for a second access on the N2 or additional lanes on the N2.
Haul roads will be required within the mine area. From a traffic flow point of view the trucks will only
cross the N2 (not travel along it) but will experience increasing delays in crossing the N2. The conveyor
system should however completely replace the truck transport. Truck driver frustration and conflict with
traffic on the N2 will be eliminated to a great extent.
Proposal C
• The truck hauling takes place on the mine side of the N2, and no additional access is implemented for
Block D. The access to the mine and the Camden Power Station remain at-grade with a bridge placed
where the haul road would best suit the mining operation. The truck trips would be completely
eliminated from using the at-grade intersection on the N2.
• The truck hauling takes place on the mine side of the N2, and no additional access is implemented for
Block D. The access to the mine and the Camden Power Station become a split-level intersection with
on- and off ramps to the N2. The at-grade intersection is completely eliminated.
