Do I need to report an environmental impact assessment for the process change of the domestic sewage

The process has changed, which is a major factor change and requires an EIA. Conduct an EIA for change.

If an EIA is required, the EIA should be changed. When conducting an environmental impact assessment for a polluting construction project, an engineering analysis should be carried out, and the impact of the project on the environment should be determined according to the engineering characteristics and environmental characteristics, and the pollution prevention and control measures that should be taken, mainly in the following aspects:

1.Process flow and pollution production links.

2.Contaminant analysis.

3.Analysis of resource and energy storage and transportation.

4.Transportation impact analysis.

5.Analysis of abnormal operating conditions.

Among them, the process flow has undergone major changes - the chemical polishing of the anode production line has changed to chemical decoating, which has changed the type of raw materials for the project (mixed acid has become 98% nitric acid), and the composition and content of pollutants in the tank have changed; According to the National Hazardous Waste List, high concentrations of nitric acid belong to hazardous wastes, which have corrosive and volatile characteristics.

The high-concentration nitric acid excluded by the project is in line with the national regulations on solid waste treatment and disposal, but it should be noted that in the process of nitric acid transfer, it must be approved by the local environmental protection department and the environmental protection department of the place of transfer, and the transfer bill should be handled.

According to the provisions of the Environmental Impact Assessment Law, if the project has undergone major changes in the production process, location, scale, environmental protection measures and other aspects after passing the EIA approval, it is necessary to re-submit the EIA procedures for approval.

If the project is small, it can be renovated by reporting to the Environmental Protection Bureau, and if the project is large, it will need to do an environmental impact assessment.

According to Article 24 of the Law of the People's Republic of China on Environmental Impact Assessment:

After the environmental impact assessment document of the construction project is approved, if there is a major change in the nature, scale, location, production process adopted or measures to prevent pollution and ecological damage of the construction project, the construction unit shall re-submit the environmental impact assessment document of the construction project for approval.

If the environmental impact assessment document of the construction project is more than five years from the date of approval before the project is decided to start construction, the environmental impact assessment document shall be submitted to the original examination and approval department for re-examination; The original examination and approval department shall, within 10 days from the date of receipt of the environmental impact assessment document of the construction project, notify the construction unit of the review opinion in writing.

If the original project has already done an EIA and approved, the rectification of the wastewater station is a change in the production process and needs to be EIA.

You need to do an EIA, but you can find a company that has an EIA to help you deal with it.

It is a major renovation and needs to do an environmental impact assessment.

According to the national "Classified Management Directory": domestic sewage treatment plants, with a daily treatment capacity of more than 50,000 tons, are to make a report, and the following are to make a report form; All industrial wastewater treatment stations make reports.

Whether an EIA is required for a project or not, and whether the EIA is a report or a report form is based on the Ministry of Environmental Protection's "Catalogue of Classified Management of Environmental Impact Assessment of Construction Projects".

According to the provisions of the "Catalogue of Classified Management of Environmental Impact Assessment of Construction Projects", new construction and expansion of domestic sewage centralized treatment with a daily treatment of 100,000 tons or more need to prepare an EIA report, and others only need to prepare an EIA report form. In any case, the sewage treatment plant is subject to an EIA.

For the sewage treatment plant project, you need to obtain the "EIA Approval" before the start of construction, and the approval given by the municipal bureau needs to be filed with the county bureau.

In other words, when you submit the trial operation report, the county bureau should know that you have approved.

If you haven't obtained the EIA approval, then the trial operation report is estimated that no one will dare to give you approval.

Other situations are not well understood.

As a sewage treatment plant, it should actively cooperate with the local environmental protection department to reduce all kinds of unnecessary troubles.

Need. For details, please refer to the "Catalogue of Classified Management of Environmental Impact Assessment of Construction Projects".

If you do upgrading and transformation, the quality and quantity of the effluent must have changed. Centralized treatment of domestic sewage and industrial wastewater requires environmental impact assessment, even if it is upgraded, it will also involve the discharge and change of pollutants. This is where an environmental impact assessment comes in.

Because the purpose of setting up a sewage treatment plant is to turn the sewage discharged in life into clean water after treatment, but in the treatment process, sometimes the treatment may not meet the standard, resulting in secondary pollution discharge, and the purpose of treatment is lost, so environmental impact assessment monitoring should be carried out.

Without oversight, there will be corruption.

To build a domestic sewage treatment plant, you need to find a special EIA agency to give you an EIA report (new construction, expansion with a daily treatment of 100,000 tons or more) or a report form, and then the environmental protection department will approve it.
