"Guangzhou Heavy Pollution Weather Emergency Plan" was issued, and the level I response was limited to single and double numbers.

Easy Car News Recently, the Emergency Plan for Heavy Pollution Weather in Guangzhou (hereinafter referred to as the "Plan") was officially issued and implemented. The plan divides the early warning of heavy pollution into three levels, from light to heavy, yellow warning, orange warning and red warning in turn; The corresponding emergency response is divided into three levels: level III, level II and level I ... Among them, when the level I emergency response is started, motor vehicles are restricted, gasoline vehicles and diesel vehicles with level II and below are restricted, and other motor vehicles (including temporary license plates, except pure electric vehicles) are restricted by single and double numbers.

From light to heavy, it is divided into three grades: yellow, orange and red.

According to the relevant provisions of the National Classification Standard for Early Warning of Heavy Pollution Weather issued by the Ministry of Ecology and Environment, the early warning of heavy pollution weather is divided into three levels, namely, yellow warning, orange warning and red warning, based on the results of air quality prediction and taking the daily average value of air quality index (AQI) as the index.

Yellow warning: it is predicted that the daily average value of AQI > 200 will last for 2 days (48 hours) or more, which does not meet the high-level warning conditions.

Orange warning: it is predicted that the daily average value of AQI > 200 will last for 3 days (72 hours) or more, which does not meet the high-level warning conditions.

Red warning: it is predicted that the daily average value of AQI > 200 will last for 4 days (96 hours) and above, and it is predicted that the daily average value of AQI >: 300 will last for 2 days (48 hours) and above; Or predict that AQI will reach 500 per day.

When forecasting 1 day (24 hours) AQI >: 200-day average, health protection tips will be released together with the air quality forecast information.

Emergency response is divided into three levels: level III, level II and level I, corresponding to yellow, orange and red warning respectively. During the air quality assurance of major events or air quality control in special seasons, the emergency response level can be improved with the consent of the leaders of the municipal government according to the needs of air quality assurance. Emergency response includes health protection measures, active pollution reduction measures and mandatory pollution reduction measures.

In a first-class emergency, motor vehicles will be restricted.

According to the "preplan", the compulsory pollution reduction measures when Class I emergency response is started include motor vehicle restriction. Construction waste transport vehicles are prohibited from driving on roads within the administrative area of this Municipality (except clean energy vehicles); Except for the motor vehicles that guarantee the normal production and life of this city, gasoline vehicles and diesel vehicles of National II and National III are restricted, and other motor vehicles (including temporary license plates, except pure electric vehicles) are restricted in single and double numbers. Operate and control diesel trucks in large enterprises, ports and logistics parks, and reserve vehicles with emission standards of five or above countries for necessary cargo transportation (except special vehicles and hazardous chemicals vehicles). Car users in large cities stop operating fuel and gas transport vehicles. Vehicles transporting bulk materials, fuel and gas are completely banned. Strengthen the sampling inspection and investigation of freight vehicles on key road sections, urban trunk roads and major traffic nodes.

In addition, the active measures of Class I emergency response include advocating bus travel and off-peak commuting. Advocate the public to travel by public transport as much as possible and reduce the number of cars on the road; Citizens consciously reduce the refueling of vehicles during the day; Appropriately increase the frequency and service life of public transport; Conditional enterprises and institutions can adopt flexible working systems such as off-duty and off-peak commuting according to the actual situation.

Refine the implementation plan of "one factory, one policy"

The plan also requires that all districts should investigate the industrial sources, mobile sources, dust sources and other pollution sources within their respective administrative areas one by one, find out the actual situation of sewage discharge, and clarify the list of emergency emission reduction projects. According to the actual implementation, the emergency ranking list can be adjusted before the end of August each year, and reported to the emergency headquarters office for the record.

Refine the enterprise's "one factory, one policy" implementation plan. The emission reduction operation plan of key enterprises should include the basic situation of enterprises, main production processes, main gas-related pollution production links and pollutant discharge, and define emergency emission reduction measures at different early warning levels, specific production lines and process links, formulate "public signs" and install them in prominent positions such as the entrance of the factory. For industrial enterprises whose processes are simple or whose production lines are shut down in turn during the early warning period of heavy pollution, only "public signs" can be made. Enterprises that are included in the list of production stoppage and production restriction during heavy pollution weather and hold pollution discharge permits should apply for changing the pollution discharge permit in time according to the emergency management requirements of heavy pollution weather and improve the emission limit requirements in special periods.

On the premise of ensuring the normal operation of the city, implement Class III, Class II and Class I emergency response emission reduction measures to ensure that the emission reduction ratios of sulfur dioxide, smoke (dust), nitrogen oxides and volatile organic compounds are not less than 10%, 20% and 30% respectively; The proportion of sulfur dioxide and nitrogen oxides can be adjusted according to the local pollutant emission composition, but the sum of the two proportions is not lower than the overall requirements. According to different primary pollutants, emergency control measures of heavy pollution weather classification are implemented: when the primary pollutant is fine particulate matter (PM2.5), the emissions of sulfur dioxide (SO2), particulate matter (PM) and nitrogen oxides (nitrogen oxides) are mainly controlled, followed by volatile organic compounds (VOCs); When the main pollutant is ozone (O3), the emission of VOCs and nitrogen oxides should be controlled.
