Azura-Edo Independent Power Plant Environmental Impact ... - IFC

Following implementation of the mitigation measures outlined above, it is
anticipated that the impact magnitude will be reduced to insignificant. The
overall residual significance of the impact will therefore become insignificant.
8.3.3 Decommissioning
The mitigation measures identified during construction shall be most relevant
for the decommissioning phase. Apart from implementing the mitigation
measures identified above, there shall be concentrated effort on the following
mitigation measures:
• Minimisation of concentrated transportation and excavation during
decommissioning to reduce erosion;
• Rehabilitation and revegetation of cleared areas adjacent to the Project site
which shall include the re-vegetation of bare soils before the next wet
season.
• Development and implementation of a waste management plan (as part of
the ESMP) to ensure that waste is disposed of correctly such that soil
contamination is minimised.
Following the implementation of the mitigation measures the magnitude may
decreased to negligible - low. The residual impact is therefore assessed to be
of insignificant – minor significance.
8.4 WATER RESOURCES
8.4.1 Construction
The following mitigation measures shall be implemented during construction
for the prevention of contamination of water resources:
• Ensure proper placement of soil stockpiles to reduce exposure of
sediment-generating materials to wind or water;
• Reduce or prevent off-site sediment transport using appropriate methods
such as effective site drainage, and sediment/silt trapping mechanisms;
• Design permanent drainage installations for heavy rainfall events and
protect stormwater channels using slope, limitation techniques, rip-rap
and lining;
• Any hydrocarbons, fuels, lubricants and chemicals to be used will be
stored in bunded and lockable oil storage tanks, with hoses and gauges
kept within the bund. Regular checking and maintenance of all plant and
machinery to minimise the risk of fuel or lubricant leakages;
