this time, the Ministry of environmental protection has issued a notice to the environmental protection departments of Beijing-Tianjin-Hebei, Shanxi, Shandong and Henan provinces (cities) and the people's governments of "2+26" cities to investigate the emission list of coal-fired boilers and "small scattered pollution" enterprises and implement the emergency plan list of heavy pollution weather. The Ministry of Environmental Protection requires that the "2+26" cities in Beijing, Tianjin and Hebei, which are air pollution transmission channels, should find out the distribution and detailed list of coal-fired boilers in use, including their geographical location, enterprise information, boiler model, scale, air pollution control facilities and emission estimation. The "2+26" city government should set up a special working group, clarify the division of functions of departments, and carry out dragnet investigation to ensure that there is no false report or omission. "Enterprises that are not included in this investigation list will be shut down once they are discovered in the future, and the relevant departments and personnel will be held accountable according to the law." The Ministry of Environmental Protection pointed out that the national inspection team will take the investigation of emission list and the formulation and solution of emergency plan for heavy polluted weather as the focus of the ongoing special air quality inspection.
