Copy the two plans of "new" for pollution weather, Chengdu will be divided into partitions and graded accurate emission reduction control

In response to Chengdu's summer ozone pollution and autumn and winter particulate pollution control, Chengdu has more scientific and accurate control measures.

On August 3, the Chengdu Ecological and Environment Bureau held a news ventilation meeting to interpret the newly revised "Chengdu Emergency Plan for Heavy Pollution Weather (Revised in 2022)" (hereinafter referred to as heavy pollution plans), and "Chengdu Ozone's Ozone Heavy Pollution Weather Emergency Plan (revised in 2022) "(hereinafter referred to as ozone plan).

According to the relevant person in charge of the Chengdu Ecological and Environment Bureau, in the two "new" plans, the "Heavy Pollution Plan" is used to prevent severe pollution of particulate matter in autumn and winter, and the "Ozone Plan" is used to prevent heavy ozone in summer. Separate revision is to make emergency measures more scientific, more accurate, and more refined. "

Early warning starting conditions for adjusting the ozone plan

Implement a partition or termination of the warning

On the whole, the early warning start -up conditions have been adjusted.

According to the development trend and severity of severe pollution weather, the warning of severe pollution weather is divided into three levels, from low to high to yellow warning, orange warning, and red warning. At the same time, the "Ozone Plan" is also divided into three levels according to the development trend and severity of ozone heavy pollution. From low to high to yellow warning, orange warning, and red warning, but the condition of yellow and orange warning is lowered. Focus on the strict red warning startup conditions.

At present, the cities of Chengdu Plain will uniformly implement the starting conditions for emergency warning of ozone over -pollution weather.

It is worth noting that according to the relevant person in charge of the Chengdu Ecological and Environment Bureau, according to the forecasting and forecasting results of air quality trends in the city and districts (cities), the newly revised "two preparations" can be paired with the city's scope or some districts (cities). The county implements early warning information in sub -regions and levels to achieve accurate management and control of partitions, and minimizes the disturbance of normal production and life.

For example, when the "Heavy Pollution Plan" starts the yellow warning, the scope of management and control is the urbanization management area of ​​the central city and the new city of the suburban area; when the orange warning is started, the scope is expanded to the city. When the "Ozone Plan" starts the yellow warning, the scope of control is the central city; when the orange warning is started, the scope is expanded to the urbanization management area of ​​the central urban area and the new city of the suburbs.

Scientific overall planning and control measures to realize the optimal emission reduction ratio

Optimize and improve emergency emission reduction measures

On the other hand, the "two plans" further scientifically coordinate control measures to achieve the optimal emission reduction ratio.

Specifically, in accordance with the rigid requirements of the emergency plan of Sichuan Province, the severe polluting weather with ozone or particulate matter is yellow, orange and red warning during the main pollution source. More than 30%.

After scientifically accurately calculating the combination of various types of emergency control measures, Chengdu has determined that the reduction of emission reductions of the "heavy pollution plan" this time is 10.6%, 20.8%, and 31.2%, respectively. 10.5%, 20.8%, and 31.5%, "This not only meets the hard requirements, but also reduces the impact to the greatest extent." The person in charge said.

At the same time, in terms of optimization and improvement of emergency emission reduction measures, it will optimize vehicles, especially freight vehicle restrictions, restricted regions, and restrictions on emissions, and strengthen mobile source control and control. Refine the types of management and control operations at different early warning levels of the construction site, and strengthen the control of pollution control and control of living sources.

In addition, the "two plans" further refined and optimized emergency emission reduction measures in the aspects of emission reduction areas and emission reduction measures. For industrial enterprises with emergency emission reduction lists incorporated into heavy pollution weather, further optimize the "one factory, one policy" differentiation emission reduction plan, "for enterprises that cannot immediately stop or discontinue production of safety hazards Implement the enterprise, to the production line, from the process, the construction site, and the work surface. "

Persist in green development orientation

Strengthen early warning and exemption policy

Specifically, in the formulation of the "one factory, one strategy" differentiation emission reduction plan, the relevant person in charge of the Chengdu Economic and Information Bureau stated that the "two plans" requirements, during the early warning period, to be included in the limits (stop) production and rotation production during the early warning period (stop) and rotation production. Industrial enterprises involving air pollutant emissions involving air pollutants should strictly follow the implementation limit of the "one factory, one strategy" plan (including the emission reduction plan of the rotation) and the emission reduction of emission reduction in the "one factory, one strategy" scheme. All equipment (production lines) involved in air pollutant emissions (production lines), which are included in the annual backward production capacity elimination plan.

At the same time, during the early warning of ozone heavy pollution weather, it will be prohibited from 8:00 to 18:00 oil tank loading and unloading gasoline operations (except for green benchmark gas stations). The urbanization management area of ​​key management areas and general management areas, ozone red warning is within the city.

In addition, the early warning exemption policy has also been strengthened this time.

During the yellow, orange and red warning of the "two plans", the A -level, B -level and leading industrial enterprises, green benchmarking sites, green sheet spray auto repair enterprises, green benchmark gas stations, new energy freight vehicles and construction machinery , Emergency rescue engineering, special vehicles, non -road mobile machinery for emergency maintenance operations, etc., implement different degrees of exemption policies.

The relevant person in charge of the Chengdu Ecological and Environment Bureau revealed that the expert technical team is undergoing in -depth scientific and technological assistance. Through the "one -to -one" consultation guidance, it helps to create green benchmarks or demonstrations for enterprises with willing, founded, and conditional conditions to lead enterprisesEssenceAs of now, there are 77 Class A, B -level and leading industrial enterprises in the city, 365 industrial enterprises in Class C (non -minimum), 1032 green benchmarking sites, 106 green gas stations, 752 green sheet spray auto repair enterprises"It not only enhances the green competitiveness of the enterprise, but also plays a good demonstration."
