What to do with the land after the chemical company is closed and relocated?

On April 22, Su Kejing, director of the Department of Soil Ecology and Environment of the Ministry of Ecology and Environment, revealed at the regular press conference of the Ministry of Ecology and Environment in April that combined with the implementation of major projects in the "14th Five-Year Plan" plan, enterprises in the chemical and nonferrous metal industries will be Focus on implementing 100 soil pollution source control projects
.

In recent years, a large number of chemical enterprises have been relocated, especially some chemical enterprises along the Yangtze River are accelerating their relocation, and the problem of soil pollution after the relocation of chemical enterprises has attracted social attention
.
Su Kejing said: "Effectively control the risk of soil pollution and ensure that land development and utilization meet the requirements of soil environmental quality.
The plots vacated after the closure and relocation of chemical companies usually have a higher risk of soil pollution, which has always been the focus of our attention
.
"

According to Su Kejing, the Ministry of Ecology and Environment has cooperated closely with relevant departments in recent years, and mainly took the following measures, which can be summarized in nine words: building a list, strict access, and risk prevention
.

The first is to bring it into the regulatory vision in a timely manner and build a list
.
Establish a national soil environmental management system for polluted plots, and share them in the departments of ecological environment, natural resources, housing, and urban and rural construction.
Land that has been engaged in production and business activities in chemical and other industries will be included in suspected contaminated plots and contaminated land according to relevant regulations.
List of blocks, timely bring the vacated land into the vision of supervision, and urge the implementation of supervision measures
.

The second is to improve the linkage supervision mechanism and strict access
.
The Implementing Regulations of the Land Administration Law clearly stipulates that when engaging in land development and utilization activities, measures should be taken to ensure that the construction land meets the requirements of soil environmental quality.
Provinces, regions and municipalities have formulated and issued specific measures for construction land access, and ensure that the land used for construction meets the requirements of soil environmental quality.
Entry gate
.

Specifically, the environmental risks of polluted plots should be considered in the planning stage, and the uses should be reasonably determined, especially the planned uses of heavily polluted plots in chemical, pesticide and other industries should be strictly controlled
.
For example, cities such as Beijing and Shanghai have planned and utilized some land plots left by chemical companies as urban green heart parks, central green spaces, and so on
.

In the stage of land use approval and planning permission, the land plots included in the soil pollution risk control and restoration list of construction land shall not be used as residential, public management and public service land
.
Strengthen supervision during the construction stage, and prohibit the construction of any projects unrelated to risk management, control and restoration on plots that fail to meet the risk management, control and restoration goals
.

The third is to promote control and repair to prevent risks
.
For the contaminated land plots to be developed and utilized, guide all localities to promote the implementation of soil pollution risk control and restoration measures in an orderly manner
.
For the polluted plots that are not to be developed and utilized for the time being, measures such as cleaning up pollution sources, delimiting isolation areas, and conducting groundwater monitoring are mainly taken to prevent the spread of pollution
.

"Strengthening the supervision of closing and relocating plots is a practical need to ensure 'safe living' at the current stage," Su Kejing pointed out.
To fundamentally ensure the safety of the living environment, it is also necessary to strengthen the pollution prevention of in-production enterprises to ensure that the land used by enterprises is no longer used.
Added soil pollution
.

The next step is to prepare for work from the following four aspects:

One is to strictly implement the soil environmental impact assessment system for construction projects
.
For construction projects that may cause soil pollution, carry out an assessment of the impact on the soil environment in accordance with the law, and propose specific measures to prevent soil pollution
.

The second is to strengthen the supervision of key soil pollution supervision units
.
In accordance with the principle of due diligence, timely update and improve the list of key supervision units, and supervise and guide the enterprises in the list to strictly implement the obligations of self-monitoring of soil pollution and investigation of hidden dangers
.
Strengthen the monitoring of soil and groundwater around the enterprise
.

The third is to implement soil pollution source control projects
.
Combined with the implementation of major projects in the "14th Five-Year Plan" plan, focusing on chemical and non-ferrous metal industry enterprises, implement 100 soil pollution source control projects, guide enterprises in production to implement pipeline, airtight transformation, and anti-corrosion and anti-seepage transformation in key areas.
As well as overhead construction of materials and sewage pipelines
.

Fourth, pay attention to the pollution prevention and control of facilities and equipment dismantling activities to prevent secondary pollution caused by improper operation
