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

• Oil interceptors and silt traps shall be put in place to manage and retain
sediments on site;
• Avoid erosion by ensuring that all roads used on and off site are suitable
for heavy vehicles (during construction and operation);
• As far as possible implement low impact excavation, in-fill and trenching
methods;
• The amount of bare ground and stockpiles shall also be minimised to
avoid silt runoff;
• 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;
• Bunding of areas where hazardous substances are stored (eg fuel, waste
areas);
8.3.2 Operation
• 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.
With the implementation of the mitigation measures listed above and
decreased erosion potential, the impact magnitude will be reduced to
moderate. The receptor sensitivity remains low, and therefore the residual
impact will remain moderate.
During operation it is important that effective site drainage and silt retention
methods have been implemented by the time the Project has reached the
operational phase. The following mitigation measures shall also be in place
during the operation phase:
• Paving of the area occupied by the plant and roads on site, which will
cover approximately 25 percent of the total area of the site ;
• The majority of the surface of the site area will be covered with gravel or a
similar material with a higher permeable surface to reduce surface run-off
particularly during heavy rains;
• 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; and
• Effective operation of the wastewater treatment plant to ensure that waste
water and oil contaminated waste water are in compliance with relevant
standards after treatment to avoid soil contamination.
