The Ministry of Environmental Protection recently issued the "Measures for Soil Environmental Management of Industrial and Mining Lands (Trial) (Consultation Draft)" (hereinafter referred to as "Measures"), and solicits opinions from relevant ministries and commissions, provincial (district, municipal) environmental protection bureaus, relevant enterprises and industry associations. . According to industry experts, the "Measures" mainly focus on the environmental management of industrial and mining enterprises in production and operation, to avoid or reduce the pollution caused by soil during the production and operation of industrial and mining enterprises. The "Measures" will make the management of soil and environment in the vast field of industrial and mining land have rules to follow.
In the "Soil Pollution Prevention Action Plan" issued by the State Council in May last year (known as "Ten Ten Articles" in the industry), 2017 is an important node. The plan proposes that according to the principle of “who pollutes and who governsâ€, the unit or individual that causes soil pollution must bear the main responsibility for governance and restoration. All provinces (autonomous regions and municipalities) completed the formulation of soil pollution control and restoration plans by the end of 2017. At the same time, the implementation of soil pollution control and restoration of lifelong responsibility system, before the end of 2017, the introduction of relevant accountability methods.
Experts said that the prevention and control of soil pollution should follow the "control increment, reduce the amount of storage" ideas. The stock of soil pollution can be slowly reduced through repair, and how to control the new soil pollution will be the key to future soil pollution prevention. This is necessary to strengthen the source control, especially to strengthen the control of key pollution monitoring enterprises. Is a mining and dressing according to "soil ten", the focus of regulatory non-ferrous metals, non-ferrous metal smelting, oil exploration, petroleum processing, chemicals, coke, electroplating, leather and other industries. According to the "Measures", the key pollution supervision enterprises refer to enterprises that are involved in the management of pollutant discharge in industries such as non-ferrous metal smelting, petroleum processing, chemical industry, coking, electroplating, and tanning; and the mining and selection of non-ferrous metal ore and oil exploitation industries. enterprise.
The "Measures" have made systematic regulations on the current status of soil and groundwater pollution in industrial and mining land, environmental access, facility leakage prevention, hidden danger investigation, enterprise self-monitoring, risk management and repair.
Soil pollution has the characteristics of concealment, latentity and accumulation, which is more serious when the problem appears. Soil pollution is largely irreversible, and it takes time and labor to repair the soil, which makes the treatment of soil pollution very complicated and difficult.
After the introduction of the Measures, the soil of the key polluting enterprises of soil pollution will be included in the environmental impact assessment in the future, as well as the survey of the soil environment.
Do a good job in soil environmental impact assessment and current status survey of key polluting enterprises. On the one hand, it can control unreasonable planning and construction projects or unreasonable policies from the source to reduce the damage to the soil environment. On the other hand, the investigation of the status quo of the soil environment is aimed at the new, reform and expansion projects of key enterprises, and to a certain extent, it is also a kind of protection for related enterprises.
At the 245th China Engineering Science and Technology Forum held in April this year, Chen Jinghe, chairman of Zijin Mining, proposed that scientific research institutions and relevant state departments should correctly distinguish the differences between soil pollution and soil metal anomalies, and generally identify natural soil anomalies as mining “pollutionsâ€. "It is neither objective nor scientific; scientific and rational mine development can not only meet the needs of the mineral raw materials needed by the national economy, but also eliminate the hidden dangers that may be brought about by hidden depths in the earth. In fact, many large metal deposits will gradually precipitate heavy metal elements such as arsenic , mercury , lead and silver under natural water erosion and weathering, forming a large area of ​​heavy metal anomalies; and rational scientific mining development and protection will not only Aggravating anomalies can improve the overall environmental quality. There have been many successful cases in the history of mining at home and abroad. Therefore, mining development enterprises and geological exploration units must adhere to the bottom line of environmental protection, pay special attention to environmental geological work, and strengthen the comparative analysis of the environmental background before and after mine development, in order to better realize the organic development of mining and environmental protection. Combine.
Environmental impact assessment is a key system of environmental management. It plays an important role in preventing and mitigating environmental pollution, promoting industrial restructuring, and strictly controlling the environmental access of macro and micro economic activities. Experts said that with the continuous improvement and advancement of soil environmental protection legislation and standards development, China has already established the basis for conducting soil environmental impact assessment.
In fact, since the beginning of this year, the Ministry of Environmental Protection, the Ministry of Land and Resources and other ministries and commissions have been accelerating the work related to the prevention and control of soil pollution. In August this year, the Ministry of Environmental Protection, together with the Ministry of Finance, the Ministry of Land and Resources, the Ministry of Agriculture, and the Health Planning Commission jointly prepared the “Overall Plan for the Detailed Investigation of Soil Pollution Status in the Countryâ€, which was approved by the State Council for implementation and implementation. The soil pollution status was investigated at the local level. Started one after another. 2017 is about to close, and the detailed investigation of the soil pollution situation in the country has begun to be carried out intensively. The restoration of agricultural land around the protection of cultivated land in many provinces has achieved remarkable results.
Analysts believe that with the increasing support of the soil remediation industry policy, the demand for soil remediation is expected to accelerate, and the soil remediation market will usher in the peak period of development during the “13th Five-Year Planâ€. However, at present, the domestic soil remediation industry is still in its infancy, and it is still necessary to construct and improve the entire industrial chain from the aspects of environmental investigation, risk management, treatment and restoration. Among them, technical support and financial support are particularly critical. In the future, a number of leading enterprises with comprehensive capabilities and a group of dynamic SMEs will still need to be promoted as a whole. (Source: China Mining News)
