The first stage is the preparation stage, and the main work is to study relevant documents,

conduct preliminary engineering analysis and environmental status survey, select key evaluation projects,

determine the work level of each individual environmental impact assessment and prepare an evaluation outline;

The second stage is a formal work stage, and its main work is detailed engineering analysis and environmental status investigation,

and environmental impact prediction and evaluation;

the third stage is the report preparation stage, and its main work is to summarize and analyze all kinds of data obtained in the second stage, give conclusions and complete the environmental impact report.
