On May 16, the Information Office of the Shaanxi Provincial People's Government held a press conference, inviting multiple departments to interpret the "Three-year Action Plan for Shaanxi Province's Iron Fist to Control Haze to Win the Blue Sky Defense War (2018-2020)" and "Shaanxi Province Iron Fist to Control Haze" Winning the blue sky defense battle in 2018 work points.

The "Plan" pointed out that the entire village in Guanzhong area will promote clean energy replacement, requiring that by the end of 2018, strive to achieve full coverage of plain rural substitution, and the replacement rate of mountainous rural areas will reach 80%; by the end of 2019, mountainous rural substitution will achieve full coverage. In the core area of ​​Guanzhong, coal-fired power generation, coal-fired combined heat and power and coal-fired central heating projects will no longer be built or expanded, and coal-fired central heating "heat source points" will be cleanly transformed.

Focusing on shutting down and eliminating, upgrading and reforming, increase the flue gas control of coal-burning enterprises; focus on replacing the old with new ones, strict management and control, and increase the control of motor vehicle pollution; focus on dismantling small and large, and clean replacement , Intensify the popularization of clean energy; focus on points and areas, promote governance, and increase dust pollution control on construction sites and urban roads.

The "Plan" has established a joint prevention and control mechanism for air pollution in the six cities and two districts of Guanzhong. It is clear that all cities, counties, and districts are responsible for keeping the land and helping each other. They must work together to interact and achieve a win-win situation. Only by adhering to coordinated control of haze, cohesive work, and concerted efforts can we achieve early results. For the first time, it is the first time that the Guanzhong area implements time and peak production measures for petrochemical, coal chemical, packaging and printing industries in summer. Clarify the effective grid supervision and reward reporting mechanism for environmental violations as important content.

Among them, the Provincial Department of Industry and Information Technology takes the lead, the Provincial Development and Reform Commission, and the municipal governments are responsible for strictly implementing the off-peak production of industrial enterprises. In the summer (June 1 to August 31) in the Guanzhong area, the petrochemical, coal chemical, coking, and cement (including special cement, excluding grinding stations) industries will be limited in production, and surface coating (including auto repair) will be implemented , The packaging and printing industry implements wrong time production. During the winter defense period (November 15 to March 15), cement (including special cement, excluding grinding station), brick kiln (excluding natural gas as fuel), ceramics (excluding natural gas as fuel) ), gypsum board, thermal insulation and refractory materials, waterproof materials and other building materials industries have all implemented suspension of production; cement grinding stations have been suspended during the warning period of heavy pollution weather; cement that undertakes major livelihood tasks such as residential heating, co-processing of urban garbage or hazardous waste, etc. Industry enterprises must approve the maximum allowable production load based on the amount of tasks undertaken; steel, coking, coal chemical, and petrochemical industries implement partial off-peak production. Each city in Guanzhong can formulate stricter peak-shift production requirements based on local actual conditions. Southern Shaanxi and Northern Shaanxi can be implemented according to the requirements for improving the air environment quality.

The 2018 "Key Points" includes three parts. The work goal part pointed out that in 2018, the average number of good days in the province's districts and cities reached 279 days, an increase of 29 days compared with 2017; the concentration of fine particulate matter (PM2.5) reached 51 micrograms/m3, a decrease of 7.3% compared with 2017. The task section specifies 29 specific tasks. The safeguard measures partly explains 7 measures.

Different regions have different approaches and strive to "finally achieve the three-year goal with difficulty"

2020 is the assessment year for a new round of blue sky defense war. All engineering measures need to be completed within 2 years to bring out environmental benefits. Therefore, in terms of the three-year task schedule, 60% of the total three-year task will be completed in 2018, and the three-year task will be basically completed by the end of 2019. In this way, the relevant measures can continue to play a role from the beginning of 2020, and finally it is possible to achieve the three-year goal with difficulty.

Different regional tasks are considered, and the regional status quo and development positioning are fully integrated. At present, the overall situation in southern and northern Shaanxi is relatively stable and fluctuates from time to time. Ankang and Shangluo should improve stability while striving to reach the standard as soon as possible. Hanzhong should catch up and narrow the gap as soon as possible; Yan'an and Yulin should continue to work hard to make a leap The development and undertaking of the transfer of industries within the province frees up more space; the urban areas in Guanzhong, as key areas, must firmly establish a game of chess thinking, in-depth implementation of joint prevention and joint governance, to ensure breakthrough progress in air pollution control.
