Closed-loop management does not leave a dead end . The relevant person in charge of the Ministry of Environmental Protection introduced that the compilation of "Ten Ten Articles" has three characteristics. First, it adheres to the problem-oriented and bottom-line thinking. Compared with atmospheric and water pollution, soil pollution is concealed, and prevention and control work starts late and the foundation is weak. To this end, the relevant departments focus on conducting investigations, finding out the bottom, promoting legislation, improving standards, defining responsibilities, and strengthening supervision. At the same time, it is proposed to firmly hold the bottom line of soil environmental quality that affects the quality of agricultural products and the safety of human settlements.
The second is to persist in highlighting key points and limited goals. Practices at home and abroad have shown that solving the problem of soil pollution requires long-term and arduous efforts. In view of the current prominent soil environmental problems that harm the health of the people, based on the basic national conditions in the primary stage, and focusing on the overall situation of economic and social development, the "Ten Ten Articles" focuses on the cultivated land in agricultural land and the contaminated land in the construction land, and clearly highlights the key pollution of supervision. Goods, industries and regions, strictly control new pollution, put more strict control measures on heavily polluted cultivated land, and clearly cannot grow edible agricultural products. Other crops are not absolutely impossible to plant; for contaminated plots, different uses are not simply prohibited, according to pollution To the extent, establish a negative list of development and utilization.
The third is to adhere to classification control and comprehensive policy. In order to improve the pertinence and effectiveness of measures, agricultural land is divided into three categories according to the degree of pollution, and measures such as priority protection, safe use and strict control are implemented respectively; for construction land, management measures are clearly defined for different purposes, and strict land access is required. Targeted control requirements have also been proposed for unused land to achieve full coverage of all land types. In terms of specific measures, targeted measures for protection, control and repair are proposed for uncontaminated and contaminated soils. The incremental control is also strictly controlled, and the stock is managed to achieve closed-loop management without leaving a dead angle.
Find out the foundation and lay a solid foundation. When answering this reporter's report on the implementation of the "Ten Ten Articles" will play a role in promoting the prevention and control of soil pollution in China, the relevant person in charge of the Ministry of Environmental Protection said that the implementation of "Ten Ten Articles" will consolidate China. The basis of soil pollution prevention and control work, comprehensively improve China's soil pollution prevention and control work capacity.
First, through the detailed investigation of soil pollution status, find out the area and distribution of soil pollution in agricultural land and its impact on the quality of agricultural products, grasp the distribution of pollution plots and environmental risks in the land of enterprises in key industries, and find out the soil pollution. family property. Second, through the revision of laws and regulations, departmental regulations, and standards systems for soil pollution prevention and control, the laws and regulations for soil pollution prevention and control have been basically established. Thirdly, through the pilot demonstration of soil pollution control and remediation, we will explore the comprehensive prevention and control model of soil pollution in the aspects of soil pollution source prevention, risk management and control, treatment and restoration, and supervision capacity building, and gradually establish China's soil pollution prevention and control technology system. The fourth is to regulate the management and repair of the units and personnel of soil pollution, to clarify the main body of governance and restoration, to implement the system of soil pollution control and restoration of lifelong responsibility, to give full play to the role of the market, and to promote the development of soil pollution control and restoration industry. Fifth, through clearing the responsibilities of all parties, strengthening information disclosure, publicity and education, and other measures to form a soil pollution prevention and control system led by the government, corporate responsibility, public participation, and social supervision.
Comprehensive and accurate understanding of soil pollution is an important basis for the prevention and control of soil pollution. To this end, it is urgent to further improve the accuracy of the investigation based on the existing investigation work, truly understand the soil pollution base, and obtain the soil pollution data of the plot size. It fully meets the needs of environmental protection, land, agriculture and health, and provides a scientific basis for the full implementation of the action plan for soil pollution prevention and control. According to reports, at present, the relevant departments are preparing a detailed investigation plan and actively preparing for various tasks.
Pilot-first industry can be expected. It has been known that six cities including Taizhou, Zhejiang, Huangshi, Hunan, Changde, Guangdong Shaoguan, Guangxi Hechi, and Guizhou Tongren have begun to build a comprehensive area for comprehensive prevention and control of soil pollution. In response to the question of how to promote the implementation of the six soil pollution prevention and control first zones, the relevant person in charge of the Ministry of Environmental Protection introduced that in 2014, the Ministry of Environmental Protection began preparations for the construction of the pilot area for the comprehensive prevention and control of soil pollution, and organized the construction plans for the prefectures in the relevant cities and municipalities. The program has passed the expert review; in 2015, the start-up zone construction start-up meeting was organized, and the construction standards of the pioneer zone were being formulated. At present, the relevant cities and towns promoted the construction according to the requirements of the construction plan. In the next step, the Ministry of Environmental Protection will strengthen the assessment and inspection of the construction of the pioneering area, and urge the relevant places to complete the construction work on time.
The person in charge also revealed that in order to coordinate and coordinate the national soil pollution prevention and control work, regular research and resolution of major problems, and the establishment of a national soil pollution prevention and control coordination mechanism. Preliminary considerations are established by the Ministry of Environmental Protection, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the Ministry of Finance, the Ministry of Land and Resources, the Ministry of Housing and Urban-Rural Development, the Ministry of Water Resources, the Ministry of Agriculture, the General Administration of Quality Supervision, Inspection, Forestry, and the Legislative Affairs Office. Inter-Ministerial Coordination Group for Soil Pollution Control.
How the industry develops will greatly affect the effects of soil management and restoration. According to reports, the cost of soil pollution control and repair varies greatly depending on the type of pollutant, the degree of pollution and the repair technology. Generally speaking, the cost of agricultural land treatment and restoration ranges from several thousand yuan to several tens of thousands per mu, and the cost of soil treatment and restoration of polluted land ranges from several hundred yuan to several thousand yuan per cubic meter.
The person in charge said that China has started research and development of soil pollution control and remediation technology during the â€œTenth Five-Year Planâ€ period, especially since the â€œTwelfth Five-Year Planâ€, with the support of special funds for heavy metal pollution prevention and control, preliminary establishment of different soil pollutants and pollution levels. Soil pollution control and restoration technologies such as land use types. The number of soil pollution control and restoration enterprises has increased from more than 10 in 2010 to nearly 1,000, and the number of employees has increased from about 2,000 to nearly 10,000. The number of projects has reached more than 300. In general, from the aspects of technical reserves and personnel, it basically has the foundation for industrial development. With the release of â€œTen Shiâ€, the soil pollution control and restoration industry chain will gradually cover the soil environment investigation, analysis and testing, risk assessment, treatment and repair engineering design and construction, and form a group of specialized soil remediation enterprises. By standardizing the management of employees and personnel, implementing the system of life-cycle responsibility for soil pollution control and restoration, and accelerating the transformation and application of results, it can promote the development of soil pollution control and restoration industry.
