Recently, Taiyuan City's comprehensive measures for the comprehensive management of the atmosphere in autumn and winter of 2017-2018 (hereinafter referred to as "tough measures") were officially launched, including 53 articles. It is clear in the tackling measures that the air quality improvement priority principle is established and implemented, and the strict assessment accountability system is implemented.

With the principle of “adhering to the principle of improving air quality improvement”, the improvement of air quality is placed in a more prominent position in economic and social development, and the city's work obedience serves the improvement of air quality. Any production, construction, operation and other activities that are not conducive to the improvement of air quality will be adjusted accordingly, and the outstanding production will be suspended or suspended, and the air quality of the provincial cities will be given priority to improve. At the same time, it is also clear that the urban area should be built into a “no-burning zone” – except for Taigang, Erdian, waste-to-energy plants and heat-retaining plants, all of which are banned.

Heavy punching and rectifying industrial pollution

From October 1st, sulfur dioxide, nitrogen oxides and particulate matter emitted by Taigang and Meijin Iron and Steel will implement special emission limits for atmospheric pollutants. From November 1st, Xishan Baijiazhuang Power Plant and Gujiao Yiyi Power Plant reached the ultra-low emission limit of coal-fired generating units. By the end of October, the comprehensive rectification work of 90 volatile organic compounds will be completed in an all-round way. Enterprises that have not completed the reform and transformation will implement the shutdown management. 272 gas stations, 12 oil storage tanks and 378 tank trucks were all equipped with oil and gas recovery treatment facilities to ensure stable operation. The annual sales of gasoline is more than 5,000 tons and other qualified gas stations to speed up the installation of online monitoring equipment for oil and gas recovery. In addition, it is clear that four 300MW units of Guodian Taiyuan No. 1 Thermal Power Plant will be shut down.

At the same time, Taiyuan City will speed up the issuance of pollutant discharge permits for key industries. If the pollutants discharged from the pollutant discharge permit have not been obtained according to law, they shall be punished according to law. For those who do not discharge according to the certificate, they shall be ordered to suspend production and rectify according to law and impose a fine; if they refuse to make corrections, they shall be punished according to law.

Implementation of industrial enterprises' peak production and transportation

Coking foundry industry: Implementing partial peak production. From October 1 this year to March 31, 2018, the coking time of coking enterprises was extended to more than 36 hours, and the coking enterprises located in urban urban areas were extended to more than 48 hours. In the foundry industry, in addition to electric furnaces and natural gas furnaces that meet the discharge requirements, the other heating seasons will be discontinued. If it is necessary to produce in special circumstances, it shall be reported to the municipal government for approval. During the early warning of heavy pollution in yellow and above, electric furnaces and natural gas furnaces were shut down.

Building materials industry: full implementation of peak production. Cement, brick kiln (excluding natural gas as fuel), ceramic (excluding natural gas as fuel), glass wool (excluding natural gas as fuel), rock wool (excluding electric furnace), gypsum board and other building materials industries, heating All production was suspended in the season.

Non-ferrous chemical industry: Optimize production regulation. In the heating season, the electrolytic aluminum plant has a production limit of more than 30%; if the carbon enterprises fail to meet the special emission limit, all of them will be discontinued, and the special emission limit will be reached, and the production limit will be more than 50%. The pharmaceutical companies involved in the production of APIs are involved in the VOC emission process and the pesticides in the production process using organic solvents. The VOC discharge process is implemented in the heating season.

Bulk material: implementation of peak transportation. During the warning period of heavy pollution weather, the key vehicle enterprises are not allowed to transport vehicles into the factory area in principle (except for transportation vehicles that ensure safe production and operation).

Comprehensively strengthen dust pollution control

The construction site management standards are clear - to achieve the surrounding area of ​​the construction site, material storage cover, earthwork excavation wet work, road hardening, ingress and exit vehicle cleaning, and muck vehicle closed transportation "six hundred percent". Various types of long-distance municipal, highway, water conservancy and other linear projects, full implementation of segmented construction. Before the end of September, online construction and video surveillance were installed on all construction sites of earth and stone above the scale, and they were networked with the competent authorities.

The muck transport vehicle must be installed with a closed device. If it does not meet the requirements for driving on the road, it shall be punished according to the upper limit and the qualification for the transportation of the waste shall be cancelled.

During the heating season, various types of road works, water conservancy projects and other earthwork operations and house demolition will be stopped. The urban built-up area basically stopped the earthwork operations of various construction projects. Major livelihood projects and key projects involving the earthwork work cannot be stopped. The project construction unit shall apply for it and the competent department of the industry shall firstly review it and report it to the municipal government for approval.

As for the steel price, in summary, with the implementation of the comprehensive measures for the comprehensive management of the atmosphere in autumn and winter of 2017-2018, the spot market has already seen a large number of goods and no inventory. Strive to minimize the risk before the production stoppage, so the steel price in Taiyuan City is difficult to get out of the shock and decline pattern in the short term.
