The general principle of environmental impact assessment has been explained in previous post. Three outcomes resulted from judging the proposed project are FONSI, EA and EIA. EA and EIS document generally consist on three parts, introduction, description of proposed project and alternatives and description of the environment affected by the proposed actions.
The introduction part of the document will state overview of the project, the purpose, alternative actions, summary of important environmental aspects and the methods of assessment being used. The description of proposed actions and alternative will describe the actions, lists of stage conducted for the project. In this part, alternatives are also mentioned, including a “no-action” alternatives as well. Statement also include the projected actions if the project is not done.
