Beijing-Tianjin-Hebei and surrounding areas 2018-2019

Action Plan for Comprehensive Management of Air Pollution in Autumn and Winter

(draft for comments)

First, the overall requirements

The main objectives: Adhere to the steady progress, and promote the continuous improvement of air quality on the basis of consolidating the results of environmental air quality improvement. Complete the air quality improvement target for 2018; from October 1, 2018 to March 31, 2019, the average concentration of fine particulate matter (PM2.5) in Beijing, Tianjin and Hebei and surrounding areas decreased by about 5% year-on-year, and the number of severe and above pollution days was larger than that of the previous year. Reduce by about 5%.

Scope of implementation: Beijing-Tianjin-Hebei and surrounding areas, including Beijing, Tianjin, Shijiazhuang, Tangshan, Handan, Xingtai, Baoding, Zhangzhou, Langfang, Hengshui, Shanxi Province, Taiyuan, Yangquan, Changzhi, Jincheng, Jinan, Shandong Province , Zibo, Jining, Dezhou, Liaocheng, Binzhou, Heze, Henan Zhengzhou, Kaifeng, Anyang, Hebi, Xinxiang, Jiaozuo, Fuyang City (hereinafter referred to as “2+26” cities, including Xiong’an New District, Xinji City, Hebei Province, Dingzhou City, Jiyuan City, Henan Province).

Basic idea: adhere to the problem-oriented, based on the industrial structure, energy structure, transportation structure and land use structure optimization and adjustment, to promote clean heating, transfer iron, enterprise upgrades and upgrades as the focus, and consolidate the results of comprehensive improvement of "scattering pollution" enterprises, Grasp the special rectification of diesel trucks, industrial furnaces and volatile organic compounds (VOCs), effectively cope with heavy polluted weather, implement peak-shooting production in autumn and winter, strengthen joint prevention and control of regional joint defense, strictly inspect accountability, and deepen the comprehensive management of air pollution in autumn and winter. action.

Second, the main task

(1) Adjust and optimize the industrial structure.

1. Strictly control the production capacity of the “two high” industries. All localities have accelerated the completion of the ecological protection red line, the environmental quality bottom line, the use of resources, and the preparation of environmental access lists, and clearly defined the industries, production processes and industrial catalogues that prohibit and restrict development. By the end of December 2018, the cities completed the red line delineation of ecological protection. Heavy polluting enterprises in urban built-up areas should implement classified disposal in a manner such as thorough shutdown, transformation and development, local transformation, and extra-territorial relocation. The relocation of heavy polluting enterprises should focus on the transfer from outside the district. Tangshan, Handan and Anyang cities are not allowed to build or expand projects, and foreign enterprises are prohibited from moving to the area.

Intensified, coking, building materials and other industries to eliminate and reduce the production capacity, included in the capacity-removing enterprises, and also withdrawn from the supporting sintering, coke oven, blast furnace and other equipment. In 2018, Hebei Province's production capacity was reduced by more than 10 million tons, Shanxi Province was reduced by 2.25 million tons, Shandong Province was reduced by 3.55 million tons, and Henan Province was reduced by more than 1.5 million tons. The elimination of 48 sets of 2.94 million kilowatts of coal-fired units was completed in the area. Hebei and Shanxi provinces have fully started the coke ovens with a carbonization chamber height of 4.3 meters and below and a service life of more than 10 years; Hebei, Shandong and Henan provinces have to set a target of 0.4 or so before the end of 2020. With the steel fixed focus program, increase the elimination of independent coking enterprises.

2. Consolidate the results of comprehensive rectification of “scattering and pollution” enterprises. All localities should establish a dynamic management mechanism for “scattering and pollution” enterprises, further improve the “distributed pollution” enterprise identification standards and rectification requirements, and resolutely put an end to the “distributed pollution” project construction and the banned “scattering and pollution” enterprises from different places and resurgence. Before the end of September 2018, all localities completed a new round of "disintegration and pollution" enterprise inspection work, and implemented the classification and disposal according to the principle of "first stop and then cure". For the closure of the category of banning, it is necessary to achieve "two breaks and three clears" (cut off industrial water, electricity, remove raw materials, products, production equipment); for the integration of relocation, environmental impact assessment according to law; The implementation of in-depth governance of the advanced enterprises will be put into operation by the relevant departments, and will be open to the public and accept social supervision.

It is necessary to carry out overall rectification of the “scattering and pollution” enterprise clusters, formulate the overall rectification plan and disclose it to the society, simultaneously promote the regional environmental remediation work, and change the “dirty and messy” production environment. If the enterprise fails to meet the requirements of the governance standards, the power company will not supply power, and the illegal power supply will be openly accountable.

3. Deepen industrial pollution control. Since October 1, 2018, the special emission limits for thermal pollutants in thermal power, petrochemical, chemical, non-ferrous (without alumina), cement industry and industrial boilers have been strictly implemented, and the upgrading of pollution control facilities in key industries has been promoted. Continue to promote the unorganized emission control of industrial enterprises, implement closed storage, closed transportation, and systematic collection, which will be basically completed by the end of 2018.

Orderly promote the industry's ultra-low emission transformation. Deepen the organized emission control, the emission concentration of particulate matter, sulfur dioxide and nitrogen oxides of sintering flue gas is not higher than 10, 35, 50 mg/m3 respectively, and other production processes are not higher than 10, 50, 150 mg/m3 respectively; Unorganized emission control, all materials storage, transportation and production workshops should be closed; clean transportation, bulk materials and products are mainly transported by rail, waterway, pipeline, new energy vehicles or vehicles that meet the national standard six emission standards. Start the coke oven body in the built-up area of ​​the city and cover and seal the work, and collect and treat the exhaust gas.

It is forbidden to add chemical parks everywhere, and increase the integration and upgrading of development zones, industrial parks and high-tech zones, and reduce pollution in industrial clusters. In accordance with the principle of “one district, one heat source”, we will promote the elimination of scattered coal-fired boilers in the park. Conditional industrial gathering areas will be built with a centralized spraying engineering center, supporting high-efficiency pollution control facilities, and replacing the independent spraying process of enterprises.

4. Accelerate the management of discharge permits. Before the end of December 2018, the cities completed the issuance of ceramic, refractory, and recycled metal industrial discharge permits, and loaded the peak production plan into the sewage discharge permit. In the industry where the discharge permit has been issued, before the end of October 2018, the cities will add the relevant peak production plan requirements to the discharge permit. We will increase enforcement of laws and regulations and penalties in accordance with the regulations, strengthen information disclosure and public supervision, and ensure that pollutant discharge units implement the main responsibilities of certified discharge, discharge according to certificates, and environmental management.

(2) Accelerate the adjustment of the energy structure.

5. Effectively promote clean and warm. Concentrate resources to vigorously promote the management of loose coal. According to the task requirements of the basic completion of life and the replacement of winter heating and loose coal in the plain area before the 2020 heating season, the local government will formulate a three-year implementation plan to determine the annual management tasks, taking into account agricultural greenhouses, livestock houses, etc. Replace work with coal. Adhere to the actual situation, take into account the clean heating and warmth of the winter; adhere to the local conditions, reasonably determine the transformation of the technical route, Yidian electricity, gas, gas, coal, heat, heat; adhere to the key points, the provinces (cities) According to the needs of the scattered coal management tasks in each city, it is necessary to rationally allocate the amount of natural gas to each city, and it is necessary to strictly lean toward the “2+26” city; adhere to the fixed demand and the gas reform, and increase the new gas volume according to the annual and heating season. Reasonably determine the number of "coal to gas" households; adhere to the first break and break, for the replacement of gas by coal, electricity by coal, etc., the original heating facilities will not be removed in the absence of gas source power.

According to local reports, before the end of October 2018, “2+26” cities had to replace 3.92 million loose coal. Among them, Beijing replaced 150,000 households, and the loose area realized “zeroing” of loose coal; Tianjin replaced 400,000 households and strived to complete the treatment of loose coal before the end of October 2019; Hebei replaced 1.64 million households, focusing on accelerating Beijing South, Shijiazhuang City, north of the bulk coal replacement work, and strive to basically complete the "no-loose coal area" in the Beijing-Tianjin Baolang stone plain area before the end of October 2019; Shanxi Province replaced 260,000, Shandong Province replaced 750,000 households, Henan Province replaced 720,000 households. All localities should be promoted as a unit by township or district. In areas where bulk coal replacement is completed, local governments should designate them as high-polluting fuel-free zones; strengthen supervision and inspection, comprehensively ban bulk coal sales outlets, prohibit sales and hoarding, and prevent re-burning of scattered coal in completed areas.

Strictly crack down on the sale of inferior coal and ensure that the quality of coal used in the administrative area is in line with national and local coal quality standards.

6. Carry out comprehensive improvement of boilers. Increase the elimination of coal-fired facilities such as coal-fired small boilers and tea stoves, operating stoves, and grain storage drying equipment (hereinafter referred to as coal-fired boilers). Adhere to local conditions and take measures.

Since October 2018, the Ministry of Ecology and Environment has released the results of dust monitoring in each city to the society every month. The provinces (cities) have announced the results of dust monitoring in districts and counties every month.

Strict construction and road dust supervision. Before the end of October 2018, cities will establish a dynamic management list of construction sites. The construction site should be surrounded by construction site enclosures, material stacking, earthwork excavation wet work, road hardening, ingress and exit vehicle cleaning, and muck vehicle closed transportation “six hundred percent”. Online monitoring and video surveillance are installed in all construction sites of 5,000 square meters and above, and are networked with relevant local authorities. Various types of long-distance linear projects such as municipal, highway, and water conservancy projects are implemented in sections. All localities should incorporate the prevention and control of dust pollution at construction sites into the “civilized construction” management scope, establish a dust control responsibility system, and include dust control fees in the project cost; the bad information that the dust management is not in place is included in the construction market credit management system, and the circumstances are serious. Enter the "black list" of the main body of the construction market; if the muck vehicle is not closed, it shall be punished according to the upper limit and the qualification of muck transportation shall be cancelled. Vigorously promote the mechanization of road cleaning and cleaning, and improve the mechanized cleaning rate of roads.

The hole discharge VOCs should be collected and treated; the process exhaust gas, the distillation device non-condensable tail gas and other process exhaust, as well as the process vessel replacement gas, purge gas, vacuum exhaust, etc. should be collected and treated.

Full implementation of the Leak Detection and Repair (LDAR) system. Leak detection of static and dynamic sealing points such as pumps, compressors, valves, flanges and other connectors, and establish a ledger to record information such as inspection time, instrument readings, repair time, and instrument readings after repair. Before the end of December 2018, the leakage rate of petrochemical equipment and pipeline components was controlled within 3 ,, and the chemical industry completed the first round of LDAR work.

Strengthen the emission control during storage and loading and unloading. Volatile organic liquids with a true vapour pressure greater than or equal to 76.6 kPa should be stored in low pressure tanks or pressure tanks; volatile organic liquids with a true vapour pressure greater than or equal to 5.2 kPa and less than 76.6 kPa. Tanks should be collected using floating roof tanks or VOCs. The fixed top tank of the treatment facility, wherein the inner floating roof tank adopts an efficient sealing method such as an immersion liquid seal and a mechanical shoe seal, and the outer floating top tank adopts a double seal. The loading of organic liquids is done by top immersion or bottom loading, and the loading facility should be equipped with an exhaust gas collection treatment system or a gas phase equilibrium system.

Strengthen the emission control of waste water, waste liquid and waste residue system. The transportation system containing VOCs wastewater should be separated from the ambient air under the conditions of safety permit; the VOCs wastewater treatment facilities should be sealed and vented to the VOCs treatment facility; the wastewater, waste liquid and waste residue should be treated, transferred or stored. The container should be sealed.

22. Promote the upgrading and upgrading of pollution control facilities. Enterprises should select appropriate technical routes based on the air volume, temperature, concentration, composition and working conditions of the exhaust gas to ensure stable discharge. Before the end of October 2018, all localities should carry out a round of law enforcement inspections on pollution control facilities of industrial enterprises VOCs, and severely crack down on market irregularities. For simple treatment processes that cannot achieve stable discharge standards, enterprises should be urged to complete rectification within a time limit. Encourage enterprises to adopt a variety of technology combination processes to improve the efficiency of VOCs governance. Low temperature plasma technology and photocatalysis technology are only suitable for treating low concentration organic waste gas or malodorous gas. The activated carbon adsorption technology should be equipped with a desorption process.

23. Comprehensively promote the management of VOCs for oil storage, transportation and sales. Before the end of October 2018, all gas stations, oil storage tanks, and tank trucks completed oil and gas recovery and treatment, and oil storage and oil and gas recovery automatic monitoring equipment installed at gas stations with annual sales of more than 5,000 tons of gasoline. We will carry out oil and gas recovery and management of crude oil and refined oil terminals and ships, and newly built oil and gas recovery facilities for shipping terminals such as crude oil, gasoline and naphtha. All new oil tankers have oil and gas recovery conditions.

(8) Effectively respond to heavy polluted weather.

24. Strengthen emergency response to heavy polluted weather. Strengthen the construction of provincial forecasting capacity. By the end of December 2018, the provincial forecasting center will realize the 7-day forecasting ability by city. Unify regional emergency warning standards and incorporate regional emergency response measures into urban emergency plans. Establish a rapid emergency response mechanism to ensure that all relevant cities respond quickly and effectively when emergency coordination is initiated. When it is predicted that a large-scale heavy polluted weather will occur in the area, the Ministry of Eco-Environment will notify the early warning information based on the regional consultation results, and each relevant city shall promptly issue an early warning according to the information of the Ministry of Eco-Environment, and initiate emergency response measures according to the corresponding level. Implement regional emergency response.

25. Consolidate emergency measures. Before the end of September 2018, the cities completed the preparation of the emission reduction measures for heavy pollution weather emergency plans, and reported them to the Ministry of Ecology and Environment for the record. In the yellow, orange and red warning levels, the emission reduction ratios of major pollutants such as sulfur dioxide, nitrogen oxides and particulate matter are not less than 10%, 20% and 30% of the total social discharge, respectively. The emission reduction ratio of VOCs is not lower than 10%, 15% and 20%.

Refine emergency measures to reduce emissions, implement them in all process steps of the enterprise, and implement inventory management. Priority is given to controlling overcapacity industries and increasing regulation and control; prioritizing and controlling high-energy-consumption and high-emission industries; peer-to-peer companies are sorting and classifying and controlling according to pollutant emission performance levels; giving priority to highly polluting enterprises in urban built-up areas and using highly polluting fuels The enterprises have taken measures to stop production and limit production. The enterprise shall formulate the “one factory, one policy” implementation plan, prioritize the process links with large pollutant emissions and rapid and safe emission reduction, and publicize the measures for stopping production and production at different emergency levels in the prominent position of the plant and accept social supervision. Innovate the supervision method, actively promote the use of electricity, video surveillance, material balance and other means to verify the implementation of various emergency response measures.

(9) Deeply promote the production and transportation of peaks in industrial enterprises.

26. Implement the peak production of differentiated industrial enterprises. All localities should reduce the emission of pollutants by the production of peaks not less than the new emission of heating, and implement high-emissions production in autumn and winter for high-emission industries such as building materials, coking, casting, non-ferrous metals and chemicals. Before the end of September 2018, the cities completed the development of the peak production plan, and refined the peak production plan to the production line, process and equipment of the enterprise. The benchmark production capacity of the company's peak production was calculated in September 2018.

Implement differentiated management, and strictly prohibit the “one size fits all” approach. The performance level of pollution emission in the industry is obviously better than that of other environmental protection benchmark enterprises in the same industry. The production should be limited or not limited; the use of natural gas, electric power, power plant heat or fuel热源的铸造、陶瓷、砖瓦、玻璃棉、石膏板、防水建筑材料、岩棉、矿物棉等企业,可少限产或不予限产;属于《产业结构调整指导目录》限制类的,要提高限产比例或实施停产。企业未按期完成治理改造任务的,纳入错峰生产方案中,实施停产治理。对涉及重大民生保障不予错峰生产的,各地要严格审核,坚决杜绝以保障民生为由规避错峰生产要求,不纳入错峰生产的项目,由相关省级部门上报工业和信息化部、生态环境部备案。

27.、焦化、铸造行业实施部分错峰生产。 In key cities such as Tianjin, Shijiazhuang, Tangshan, Handan, Xingtai and Anyang, the production capacity in the heating season is limited to 50%; the proportion of production in other cities is not less than 30%, and the provincial government plans to formulate implementation plans; Metering, supporting sintering, coke oven and other equipment synchronous stop production, using the actual electricity consumption of the enterprise to verify.企业有组织排放、无组织排放和大宗物料及产品运输全面达到超低排放要求的,可不予错峰,在橙色及以上重污染天气预警期间限产50%,由相关省级部门上报生态环境部、工业和信息化部备案;仅部分生产工序和环节达到超低排放要求的,仍纳入错峰生产实施方案,按照排放绩效水平实施差异化错峰。秋冬季期间,焦化企业出焦时间延长至36小时以上;焦炉炉体加罩封闭、配备焦炉烟囱废气脱硫脱硝装置且达到特别排放限值的,可不予错峰。铸造行业除满足达标排放要求的电炉、天然气炉外,其他铸造熔炼设备(含铸造用生铁高炉)采暖季实施停产,特殊情况确需生产的,应报地市级人民政府批准;电炉、天然气炉在黄色及以上重污染天气预警期间应停产。


29.有色化工行业优化生产调控。在采暖季,电解铝产能限产30%以上,以停产电解槽的数量计;氧化铝产能限产30%,以生产线计;炭素产能限产50%,以生产线计;有色再生行业熔铸工序限产50%。 For pharmaceutical companies involved in the production of APIs, VOCs are involved in the VOCs emission process, and the pesticides that use organic solvents in the production process are involved in the VOCs emission process. In the heating season, the production is suspended. In the case of special needs such as people's livelihood, production is required. Approved by the people's government.
