Division, grading precision emission reduction control!To deal with pollution weather, the two emergency plans in Chengdu are "new"

Continue to improve the city's air quality and prevent the impact of heavy pollution on the health of the people's health, Chengdu once again "new" two emergency plans. On July 30, Red Star News reporter learned that "Chengdu Ozone Emergency Plan for Ozone Heavy Pollution (Revised in 2022)" (hereinafter referred to as the "Ozone Plan") and Chengdu Emergency Plan for Heavy Pollution Weather (Amendment of 2022) "(following It is said that the "heavy pollution plan") has been officially released through the website of the Chengdu Government, which has put forward more accurate requirements for Chengdu's summer ozone pollution and autumn and winter particulate pollution control.

Newly adding partitional warning, precise emission reduction control and control

Judging from the "two plans" just released, the warning start -up conditions have been adjusted. Among them, in accordance with the relevant requirements of the "Sichuan Province Emergency Plan (Trial)" in 2022, the "Heavy Pollution Plan" has not been adjusted, according to the development trend and severity of heavy pollution weather, the warning of severe pollution weather is divided into division into the development trend and severity of severe pollution weather. Three levels, from low to high, are yellow warning, orange warning, and red warning. The "Ozone Plan" is also divided into three levels according to the development trend and severity of ozone heavy pollution weather. From low to high to yellow warning, orange warning, and red warning, but the condition of yellow and orange warning is lowered, focusing on additional additional additions Strictly strictly start the conditions of the red warning.

It is worth noting that in order to further improve the scientificity of severe pollution weather prevention and control, to achieve the accuracy of the release and emergency emission reduction of severe pollution weather early warning information, under the conditions of existing technical capabilities, according to the air quality of the air and counties (cities) and counties Regional forecasting and forecasting analysis results, the newly revised "two plans" can issue a sub -region and levels of the city or some districts (cities) and counties to issue early warning information to achieve partitioned management and control, minimize the control of heavy pollution weather emergency control and control Impact on normal production and life. In the future, the city's scope or some districts (cities) and counties will start a yellow warning, and will be approved by the Chengdu "Three Battle" Office. The city's scope or some districts (cities) and counties start orange and red warnings (including yellow warning to orange warning, orange warning to red warning). After approval by the leadership group of the "Three Battle" in Chengdu, it was "three major major in Chengdu City "Battle" was released. The early warning was released 24 hours ahead.

Implement differentiated control under green guidance

Sorting out the contents of the "two plans", the most concerned is that the new plan will accurately reduce emission reduction, fine control as the overall direction of pollution prevention and control, and further refine it in the aspects of emission reduction ratio, emission reduction area, and emission reduction measures And optimized emergency emission reduction measures.

In the emission reduction area, comprehensive consideration of the source of pollution sources, population agglomeration, emissions intensity, etc., as well as the harm of particles and summer ozone in winter. Precise emission reduction. When the "heavy pollution plan" starts the yellow warning, the scope of management and control is the urbanization management area of ​​the central urban area and the new city of the suburbs. When the orange warning is started, the scope is expanded to the city. When the "Ozone Plan" starts the yellow warning, the scope of management and control is the central urban area. When the orange warning is started, the scope is expanded to the urbanization management area of ​​the central city and the new city of the suburbs.

In terms of emission reduction measures, the two newly revised plans have been further optimized and improved, especially to optimize vehicles, especially cargo vehicles, restricted travel time, regional, and emission stages, and strengthen mobile source control. For industrial enterprises with emergency emission reduction lists incorporated into heavy pollution weather, further optimize the "one factory, one policy" differentiation emission reduction plan, and implement subsequent and batches of chemicals, brick and tile kiln and other enterprises that cannot be discontinued or suspended immediately. Production, can be quantified, executed, checked.

For example, during the yellow warning of ozone heavy pollution weather, the key management zone prohibited the construction site soil and stone operations, building components, pavement milling, pile operations, and house removal of the construction site during the period of time from 20:00 to 8:00 the next day. From 21:00 to 7:00 the next day, construction waste (including engineering residue) transportation vehicles, pre -mixed concrete transport vehicles, and pre -mixed mortar transport vehicles are prohibited from passing. Except for energy vehicles and national emission standards above the national (including) or above. During the orange warning, the urbanization management areas of key management areas and general management areas must be transported by construction waste (including engineering residue) transport vehicles, pre -mixed concrete transportation vehicles, pre -pre -mixed concrete transportation vehicles, pre -mixed concrete transportation vehicles from 21:00 to 7:00 the next day. Mix mortar transport vehicles are prohibited from passing, and asphalt hybrid transportation vehicles are prohibited 24 hours a day.

In addition, the "two plans" also further highlights the development orientation of green and low -carbon, focusing on the exemption of enterprises' independent emission reduction measures at different early warning levels. The "Ozone Plan" and "Severe Pollution Plan" are leading A and B -level leading industrial enterprises, green benchmarking sites and emergency rescue engineering, green sheet spray auto repair enterprises, green benchmark gas stations, leading business mixed stations, new energy sources, new energy sources Verse -exemptions such as transport vehicles, special vehicles, and emission standards such as the Sixth and above of the Sixth and above.
