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

Emissions of Greenhouse Gases
The proposed facility will contribute to greenhouses gases through the
emission of fossil fuel derived carbon dioxide (CO 2) to the atmosphere. The
main source of CO 2 emissions during operation is the combustion of natural
gas to generate power. GHG emissions from the proposed facility, as
provided by Azura Power, is calculated to be a total CO 2 emissions of 2,718
kt/yr.
This value exceeds the IFC Performance Standard 3 for Pollution Prevention and
Abatement threshold for a single project/ development of 100 kilo tonnes CO 2-
equivalents per year for a single project or development, and is therefore
considered a significant negative impact.
7.3.8 Impact Description and Significance: Decommissioning
Impact Description
With regard to air quality, there are no specific positive impacts relating to the
decommissioning of the proposed project. The negative impacts identified
during decommissioning activities are due to emissions of dust resulting from
demolition of buildings, site levelling and filling activities at the site. There
may also be some emissions due to traffic associated with decommissioning.
This analysis demonstrates that for >89 percent of the year the weather
conditions (all wind directions) are such that significant dust generation is
unlikely. For the remainder of the year (11 percent), any generated dust will
migrate towards north and northeast where this may impact three of the
eastern most receptors in the communities of Orior-Osemwende and the
western most receptor within the Ihobvor-Evboeka community (see Figure
7.3). The remainder of the receptors within the community of Ihobvor-
Evboeka are over 1 km from the areas of the site to the south and south west
and are therefore unlikely to be impacted by dust emissions. The community
of Idunmwumowinna-Uhro-Nisen lies to the south of the site and is therefore
unlikely to be impacts by dust generated due to wind direction.
Impact Significance
The duration of the decommissioning period is expected to be less than a year
