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

• 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;
• Azura Power shall carefully decommission the groundwater abstraction
boreholes, or if they are to remain in continued use, ensure they are
capped to prevent the development of a potential pathway for
contaminants.
• Ensure correct disposal of demolition waste and chemicals (including
transformer oil, residual sludge from the wastewater treatment works and
diesel) and/or incidents and spills.
With the implementation of the mitigation measures during
decommissioning, the residual impact magnitude will be reduced to
insignificant - low but the residual impact on water resources will remain of
minor significance.
The negative impact of groundwater use on groundwater resources will
remain insignificant.
8.5 BIODIVERSITY
8.5.1 Construction
The following mitigation measures shall be implemented in the construction
phase of the Project:
• Vegetation clearing shall be limited to areas where it is absolutely
necessary. The development of biodiversity management plan (BMP)
which will include demarcation of the floral species on site by a botanist,
identifying measures to protect floral species from accidental damage
during construction. To the extent possible the site design will consider
retaining as many floral species as possible, and the relocation of those
that cannot be retained and protected;
• Provide training to staff to enable the identification of all floral and faunal
species of a Threatened status. An anti-poaching policy will also be
communicated to staff;
