Check sewage outfall, "one by one" remediation

The quality of ecological environment has become a weak link in Nanjing's efforts to build a well-off society at a high level. In order to implement the central and provincial, municipal decision-making and deployment, in-depth implementation of the "two reduction of six treatment and three promotion" special action, recently, the 32nd meeting of the Standing Committee of the 15th Municipal People's Congress passed the "Nanjing Municipal People's Congress Standing Committee on vigorously controlling air, water, soil pollution to speed up the improvement of environmental quality". The "Decision" firmly grasped the key factors and weak links affecting Nanjing's environmental quality, and put forward specific and clear opinions on reducing the total amount of coal consumption, adjusting and optimizing the industrial structure, and regulating black and smelly rivers, etc. All the rules and regulations are highly targeted and rigid.

We will strictly control the consumption of coal in new coal-burning projects, and shall not build new coal-burning boilers or coking projects

Controlling total coal consumption is not only a major measure to improve the quality of atmospheric environment, but also a basic requirement for adjusting industrial structure. "Since the 12th Five-Year Plan, the total coal consumption in our city has been running at a high level." Wei Changming, director of the Environmental Resources and Urban Construction Committee of the Standing Committee of the Municipal People's Congress, said that according to the analysis, coal accounted for 27.4% of the PM2.5 source analysis in the city.

To this end, the "Decision" proposes to strictly control the construction of new coal-fired coal consumption projects, except for public coal-fired back pressure units, not to approve new coal-fired power generation and heating projects and construction projects using coal as the main raw material, not to build new coal-fired boilers, coking projects. We will vigorously promote the optimization and integration of coal-fired units and the transformation of coal into gas, accelerate the upgrading of coal and electricity and the energy conservation of major energy users, and strive to reduce the total coal consumption of the city to less than 28 million tons by 2020. To actively develop clean energy and ensure that the proportion of non-fossil energy consumption in the city reaches 6\% by 2020.

Strictly implement the negative list of chemical industry and prohibit restricted items from entering the park

It is understood that the city's industrial structure is heavy, economic growth on heavy chemical industry dependence, high pollution, high energy consumption of heavy chemical industry accounts for a larger proportion (light and heavy industrial ratio of 22.5:77.5), power, petrochemical, steel, cement and other four industries, 2015 output value although only accounts for the total industrial output value of about 35\%, The emissions of sulfur dioxide and nitrogen oxide accounted for 81.7\% and 95.7\% of the city's total emissions respectively.

According to the Decision, the city will speed up the structural adjustment of the chemical industry, greatly reduce the number of chemical enterprises, strictly implement the emission standards, resolutely eliminate the enterprises that do not meet the emission standards and do not achieve the transformation, and ensure that the number of production enterprises in the chemical industry park accounts for more than 80\% of the chemical enterprises in the city by 2020. Strictly implement the negative list of chemical industry, prohibit restricted projects from entering the park, and prohibit the construction or expansion of chemical projects outside the park. We will promote the relocation, transformation and upgrading of relevant enterprises.

We will promote the development of drainage areas that meet standards, and plan to build rain and pollution networks in new towns and new areas to meet high standards

"At present, our city water environment quality standard level is low, urban water is generally black and smelly, there are bad V water bodies." Wei Changming believes that no matter completing the tasks of the national, provincial and municipal Action Plans for Water Pollution Prevention and Control, or improving the public environmental satisfaction rate, it is necessary to carry out the remediation of sewage discharge (water) mouth into the river and lake as soon as possible, establish the city's sewage discharge (water) mouth system archives into the river and lake, and formulate and implement the remediation plan.

The "Decision" proposes to speed up the rectification of sewage discharge (water) outlets into rivers, check key rivers, rivers with sections above the provincial examination level and their tributaries, formulate and implement remediation plans in accordance with the "one step, one policy" principle, and ensure that 109 black and smelly rivers will be completed by 2017. We will continue to develop drainage areas that meet standards, speed up the transformation of drainage systems based on a split drainage system, and plan and develop rainwater and pollution pipe networks and river facilities in new towns and districts to a high standard. We will accelerate the construction of sewage treatment facilities and establish a mechanism to ensure that by 2020 the sewage treatment rate in cities and towns will be at least 95\%, and all towns will have full coverage of sewage treatment facilities, and the coverage rate in villages will be at least 90\%. In accordance with the law, we will strictly investigate and punish the illegal acts of discharges in violation of regulations or exceeding the standard, and seriously investigate the administrative, civil and criminal responsibilities of the violators.

Soil pollution investigation should be carried out to master the soil environmental quality of all types of land

"Soil pollution control is costly, long and difficult. Since last year, The State Council and Jiangsu Province have issued action plans and work programs for soil pollution prevention and control, which have put forward clear requirements for relevant work." Wei Changming said that at present, the city's soil pollution control foundation is still relatively weak, "three high and two low" after the end of enterprise remediation, a large number of retired sites need to be repaired.

Therefore, "Decision" proposed to promulgate and implement "Nanjing Soil Pollution Prevention and Control Work Plan", strictly control new soil pollution, gradually reduce the stock of pollution, to ensure the quality of agricultural products and the safety of the living environment. Carry out soil pollution survey to grasp the soil environmental quality of all kinds of land; Implement classified management of agricultural land to ensure the safety of agricultural production environment; Implementing access management for construction land to prevent risks of human settlements; Strengthen prevention work, protect unpolluted land; Strictly control existing pollution sources and curb the spread of underground water and soil pollution; Highlight key areas, industries and pollutants, and control and repair contaminated soil. Increase investment, strengthen law enforcement, supervision, monitoring and information technology capabilities, ensure the safe use of soil, and ensure that by 2020, the overall quality of the city's soil environment remains stable, soil environmental security of agricultural land and construction land is basically guaranteed, and soil environmental risks are effectively controlled.

We will strengthen rigid constraints and strictly implement the environmental protection access system and pollutant discharge standards

At present, although the city has issued the "Implementation Plan on the establishment of strict environmental access system" and "Nanjing Construction Project Environmental Access Interim Provisions", but to a considerable extent, there are still problems of environmental protection access system and emission standards are not strictly implemented.

According to the "Decision", the main function zoning, ecological red line regional protection planning and ecological environmental protection planning of Nanjing shall be strictly implemented, the rigid constraints of "space, total amount and access" shall be strengthened, and the admission of new enterprises and new projects shall be well achieved according to the strictest standards. No project that does not conform to the environmental function zoning and ecological red line regional protection planning shall be approved for construction. New construction projects will be restricted to areas with degraded environmental quality, serious environmental pollution and prominent environmental violations. We will strictly implement the discharge standards for pollutants, implement a plan to fully meet the discharge standards of industrial pollution sources, and ensure consistent discharge standards through comprehensive measures such as cleaner production upgrading, in-depth pollution control, limiting production and discharge, and shutting down operations. In the chemical, steel, electric power, cement, casting, electroplating and other industries, outdated technologies, equipment and production capacity that cause serious pollution will be phased out. Those whose emissions fail to meet standards will be brought under control within a specified time limit.
