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

Type of Emission
Solid waste
All solid wastes generated during construction (surplus spoil) and
operation (waste chemicals, office waste and small amounts of
hazardous waste) will be disposed of at an appropriately licensed
landfill site. Azura Power will identify appropriate landfill sites
during the detailed design phase.
Project Schedule
It is estimated that the facility will be operational by second quarter of 2015. Site
preparation and construction is expected begin in the fourth quarter of 2012 and
to be completed by the fourth quarter of 2014. Testing and commissioning is
expected to be undertaken between the fourth quarter of 2014 and be completed
by the first quarter of 2015. The lifetime of the Project is expected to be 20 years
and decommissioning to take place from 2035.
Project Activities
Construction Phase
Project activities will commence with site clearance of vegetation, earthworks,
site levelling and construction of site roads. The “lay down” area will be on the
area reserved for the Heat Recovery Steam Generators (HRSGs) and steam
turbines. A temporary construction camp will be established to house the
employees during the construction phase within the site (on the western portion)
and will include (to be confirmed on appointment of EPC contractor) housing,
kitchens, eating areas and latrines. Site preparation will involve vegetation
clearing activities and removal of organic material, removal of unsuitable
material and top soil, and levelling and compaction, including cut to fill, and
borrowing to fill from an approved source of material.
Screw piling (auger piling) of the foundations for the gas turbines and other
large items of equipment will commence six months into the construction
schedule, and will last for three to four months. Once the piles are in place,
concrete slabs and turbine pedestals will be formed using large concrete pours.
The gas turbine building and overhead 330 kV cables will be constructed at
around 15 months while gas turbines and other heavy equipment will be
delivered at 12 - 18 months, associated with abnormal loads on the roads. Raw
materials will be sourced locally to the extent possible.
Construction will generally be during daylight hours, however the final stages of
installation and commissioning may proceed 24 hours a day, seven days a week
Approximately 500 people will be employed during the construction phase and
up to 70 percent of the construction workers can be sourced locally, from within
30 km of the Site.
