Environmental impact assessment (環境影響評估) was required to ensure that this project will not generate environmental pollution exceeding the tolerated maximums suggested by scientists before officially approving to proceed with the project.
The EIA mainly consists of two stages (see the next slide for details):
In the first stage, EIA committee members review the application and make a decision about whether the project may have significant impact on environment. If not, the application passed the environmental impact assessment. If yes, then go
