On February 29, Premier Wen Jiabao presided over the executive meeting of the State Council and agreed to issue the newly revised "Ambient Air Quality Standards" to deploy and strengthen the key work of comprehensive prevention and control of atmospheric pollution. On the same day, the Ministry of Environmental Protection issued the revised "Ambient Air Quality Index (AQI) Technical Regulations (Trial)" and "Notice on Implementation of Ambient Air Quality Standards." On March 2nd, at the press conference held by the State Council Office, Wu Xiaoqing, Vice Minister of MEP stated that this move has a milestone in the history of China's environmental protection and marks the beginning of environmental protection work from the stage of pollutant control and management. Change to environmental quality management and risk prevention. Wu Xiaoqing, inter alia: "Pollution Prevention is always the top priority of environmental protection, involving key industries including heavy metals, petrochemicals and so on." Experts from the Environmental Protection Division of the Ministry of Quality, Safety and Environmental Protection of the China Petroleum and Chemical Industry Federation stated that on the one hand, the development of new standards for ambient air quality shows that the state attaches great importance to ambient air quality, and the petrochemical industry will increase its backward production capacity. Elimination efforts will also accelerate the adoption of advanced sulfur dioxide treatment technologies to deepen energy conservation and emission reduction in the industry. On the other hand, the new standards are also beneficial to the energy conservation and environmental protection industries in the petrochemical industry. Zhao Hualin, Director of the Department of Pollution Prevention and Control of the Ministry of Environmental Protection, said in an interview with this reporter: “The promulgation of the PM2.5 standard has brought air pollution prevention and control into a new phase. It controls pollution from the local government to the joint prevention and control of the region, and controls once. The conversion of pollutants to control of secondary pollutants, from individual control of individual pollutants to coordinated control of multiple pollutants, is of great significance for improving the quality of the environment, adjusting the industrial structure, and transforming economic growth patterns.†He also stressed that the new standard has been adjusted. Environmental air function zone classification, classifying three types of districts (specific industrial zones) into second-class zones (residential zones identified in town planning, commercial traffic residential mixed zones, cultural zones, general industrial zones, and rural areas), and integrating industrial zones with In the same way, the petrochemical industry will no longer enjoy special care. According to Wu Xiaoqing, compared with the current "Ambient Air Quality Standards", the new standard emphasizes the protection of human health as the primary goal. It has adjusted the classification scheme of the ambient air function zone and further expanded the scope of protection of the crowd; adjusted the pollutant items and limits Addition of the PM2.5 average concentration limit and the ozone 8-hour average concentration limit; tightened the concentration limit of pollutants such as PM10, tightened the validity of the statistical data of the monitoring data, and the effective data requirements from the original 50 From 70% to 75% to 75% to 90%; updated analysis methods for pollutants such as sulfur dioxide, nitrogen dioxide, ozone, and particulates; added automatic monitoring and analysis methods; clarified the regulations for the implementation of standards by stages, and stipulated that standards were not met. Key cities for prevention and control of atmospheric pollution shall formulate and implement compliance plans according to law. In response to the implementation of the new standard, the "Notice" requires that environmental access thresholds be increased: that is, strictly control the entry of new projects, strictly control the excessive growth of "two high and one capital" projects and overcapacity industries, and export of products; strengthen regional industries. Develop environmental impact assessment plans and strictly control the expansion of production capacity projects in industries with excess capacity such as steel, cement, flat glass, traditional coal chemical, polysilicon, electrolytic aluminum, and shipbuilding. The "Notice" also requires that the prevention and control of motor vehicle pollution be effectively strengthened. Take economic incentives and constraints to the same time, and accelerate the advancement of vehicle fuel quality and the implementation of motor vehicle emission standards to improve the level of vehicle fuel cleanliness. For the implementation of joint prevention and control of air pollution as required by the State Council's executive meeting, the "Notice" proposes to implement air pollution prevention and control plans in key regions such as the Beijing-Tianjin-Hebei region, the Yangtze River Delta, and the Pearl River Delta, increase industrial adjustment efforts, and accelerate the elimination of outdated production capacity. The "Notice" requires the active promotion of clean energy and the launch of a trial of total coal consumption control. At the same time, we must implement multi-pollutant collaborative control, formulate and implement more stringent emission limits for air pollutants in key industries such as thermal power, iron and steel, and petrochemicals, and vigorously reduce the total emissions of sulfur dioxide, nitrogen oxides, particulate matter, and volatile organic compounds. It is a major highlight of the new standard to confirm that air pollution control requires regional control. China's chemical companies are mainly concentrated in the Yangtze River Delta and Pearl River Delta regions. According to the new ambient air quality standards, relevant departments will certainly increase supervision and strictly control. In addition, Wu Xiaoqing pointed out that the "Notice" clearly stipulates that in 2012 in Beijing, Tianjin, Yangtze River Delta, Pearl River Delta and other key regions as well as municipalities and provincial capitals, in 2013 in 113 major environmental protection cities and environmental protection model cities, 2015 in all Cities above prefecture level, implementation requirements for implementation of new standards across the country on January 1, 2016. Therefore, January 1, 2016 is the closing time for this standard to be implemented nationwide.

The Ministry of Environmental Protection is organizing the preparation of air pollution prevention and control plans in key regions. Through the optimization of industrial structure, improvement of energy structure, implementation of multi-pollutant and other coordinated control, it will strengthen industrial pollution control and effectively reduce emissions of sulfur dioxide, nitrogen oxides, particulates, and volatile organic compounds. We will strive to improve the particulate matter, sulfur dioxide and nitrogen dioxide in some key cities by 2015, and the regional air pollution such as PM2.5 and ozone will be initially controlled.
