9 CUMULATIVE IMPACTS In theory, any development such as the Azura power plant may also be taking place at the same time as other developments, causing impacts affecting the same resources or receptors, such that there will be cumulative effects with the proposed Project. The impacts of developments already underway or committed (in particular, the neighbouring NIPP plant and the associated construction of the substation) have been taken into account in modelling future air and noise emissions and assessment of these impacts by including them in the future baseline for the Project within this impact assessment. Apart from the NIPP plant, research of relevant documents (eg the EIA for the neighbouring NIPP facility) and consultations with local and state authorities has not identified any other significant future developments whose cumulative impacts should be considered in this ESIA. 9.1 AIR QUALITY The proposed Azura IPP plant is located adjacent to the NIPP plant, which is currently under construction and during operation will release similar emissions to that of the Azura Edo IPP. As such, an assessment of the cumulative air quality impacts will need to understand the impacts related to the operation of both plants. Based on the limited public information about the details of the design of the neighbouring NIPP plant, it has been assumed that the plant and emissions and impacts will be the same as that of the Azura Edo IPP. This is considered to be a reasonable assumption, as both power plants operate on natural gas and are of a similar production capacity. The assessment of cumulative impacts was performed by modelling the emissions from both plants. The results of the assessment of cumulative impacts are presented in Figure 9.1 and Table 9.1 below. Cumulative impacts from the Project and neighbouring NIPP have been quantified for NO x (Table 9.1), but not for CO, as these levels are considered to be very low and not associated with significant impacts on air quality. The cumulative dust impacts are also expected to be low since the construction phase for the NIPP will be completed once the construction of the Azura Edo IPP is initiated.
