Hello, generally, this kind of certificate, which requires the signature and consent of nearby residents, is a public participation link in the project EIA. The main reason is that your project may have an environmental impact on nearby units or individuals, and you need to ask their opinions and suggestions. For example, catering projects need the opinions of your neighbors and residents upstairs and downstairs. This is the procedure that the environmental protection department needs to go through when approving the project. Mainly to avoid disturbing people's complaints in the future, there will be public participation opinions in the EIA documents, so you should sign them one by one, remember, and have a good attitude. . .
