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

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 withinthe 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 construction period is expected to last approximately two
years and thus the dust-generating activities are likely to occur for >12
months. The conditions are unsuitable for dust-generation on site for > 89
percent of the time and although there are only a small number of receptors
(within the Orior-Osemwende and Ihobvor-Evboeka) within 200 m of the
source, these receptors are highly sensitive to these impacts.
The impact of dust on surrounding receptors is therefore considered to be
major prior to mitigation and steps will need to be taken to minimise the
effects.
The emissions arising from traffic associated with the construction activities
on the local receptors are considered likely to be insignificant due to the low
number of vehicles.
7.3.7 Impact Description and Significance: Operation
With regard to air quality, there are no specific positive impacts relating to the
operation of the proposed project. The negative air quality impacts predicted
during operation are related to the following:
• Process emissions (NO x and CO);
• Cumulative process emissions (NOx and CO); and
• Greenhouse Gases.
During operations there are unlikely to be any significant emissions of dust or
odour and these have therefore not been assessed. In addition, there will be
relatively few vehicles movements associated with the operation of the
facility, and therefore impacts associated with road traffic have also not been
assessed.
