How many times should Beijing subway EIA be publicized?

Beijing subway EIA publicity generally needs once. Publicity of environmental impact assessment refers to the process that the construction unit discloses the contents of the environmental impact assessment report or environmental impact registration form to the public and accepts public supervision and opinions and suggestions in accordance with national and local regulations. In the process of EIA, if there is something that needs to be modified in the EIA report or the environmental impact registration form, the construction unit needs to supplement or modify it and publicize the EIA again.
