According to the degree of environmental impact of construction projects, the state implements classified management of environmental impact assessment of construction projects. Environmental impact assessment documents can be divided into three forms: environmental impact report, environmental impact report form and environmental impact registration form.
Construction projects that produce waste water, waste gas, waste residue, dust, noise, vibration, electromagnetic radiation, radioactive substances, toxic and harmful substances, odor, etc. during the construction process or after the completion of the project. Environmental impact assessment shall be conducted for the needs affecting environmental quality. According to the degree of environmental impact of construction projects, the environmental impact assessment of construction projects shall be managed at different levels:
1. If the construction project may cause significant environmental impact, an environmental impact report shall be prepared to comprehensively evaluate the environmental impact;
2, the construction project may cause slight environmental impact, it shall prepare an environmental impact report, environmental impact analysis or special evaluation;
3. For construction projects that have little impact on the environment, an environmental impact registration form shall be filled in.
EIA documents are not required by every enterprise, but only by construction projects. According to the level of EIA documents, it can be divided into three categories: construction project environmental impact report, construction project environmental impact report form and construction project environmental impact registration form.
Classification of environmental impact assessment
A, according to the evaluation object, environmental impact assessment.
1, planning environmental impact assessment
2, the construction project environmental impact assessment
The second is to conduct environmental impact assessment according to environmental factors.
1, atmospheric environmental impact assessment
2, surface water environmental impact assessment
3, acoustic environmental impact assessment
4. Eco-environmental impact assessment.
5, solid waste environmental impact assessment
Third, in chronological order, environmental impact assessment.
1, environmental quality status evaluation
2, environmental impact prediction and evaluation
3. Post-evaluation of environmental impact
