Summary of Environmental Impacts and Mitigating Measures All the impacts that are likely to be generated by the proposed Project is summarized in Table E. Mitigating measures specifically proposed for each of the impacts are also presented in a systematic manner in accordance to pre-construction, construction and operational phase. Hence, such data enable convenient identification of impacts along with their respective temporal (i.e., acute or residual) and spatial (i.e., magnitude) considerations.
