Jinhua's Comprehensive Air Pollution Control
On the afternoon of September 16, the Jinhua Leading Group Office for the Blue Sky Protection Campaign (JLG) held a meeting to kick off the Campaign and comprehensively control the air pollution in the autumn and winter of 2019 and 2020. The leaders of 14 municipal departments—including the Jinhua Development and Reform Commission, the Jinhua Municipal Bureau of Economy and Information Technology, the Jinhua Public Security Bureau, and the Jinhua Ecological Environment Bureau—and the heads of the JLG from Jinhua's counties, cities, and districts participated in the meeting. The theme of the meeting was the protection of Jinhua's blue sky this autumn and winter.
According to the data from the JLG, the particulate matter at 2.5 (PM2.5) concentration in the urban area of Jinhua was 28 μg/m3 from January to August this year, which was a 12.5% decrease compared with the same period in 2018. The percentage of days with good air quality was 90.9%, and the number of days with good air quality was 221, increasing by 7 days from the same period last year.
The PM2.5 concentration of Jinhua's counties, cities, and districts ranged from 21 to 32 μg/m3. Pan'an County had the lowest PM2.5 concentration (21 μg/m3), while Jinyi Urban District had the highest (32 μg/m3). The PM2.5 concentration of Pan'an County ranked seventh among the 58 counties and cities in Zhejiang.
In order to better protect Jinhua's blue sky, the meeting agreed on many key actions for comprehensive air pollution control. The strict control of non-road mobile machinery (NRMM) was particularly highlighted.
According to the agreement, before the end of December of 2019, Jinhua will complete the investigation and registration of NRMM, fully understand the necessary scope of work of NRMM in Jinhua, and establish a database for Jinhua's NRMM. The machinery investigated and registered mainly include excavators, cranes, loaders, bulldozers, rollers, pavers, graders, forklifts, pile drivers, tractors, and on-site vehicles, among others.
In addition, Yiwu and the urban area in Jinhua will delimit and announce areas that are prohibited for NRMM with high air pollutants, according to the requirements of environmental functional zoning and the ecological red line, based on the NRMM information in the database. NRMM emissions in prohibited areas should meet the requirements of Class III limits specified in Table 1 of the Limits and Measurement Methods for Exhaust Smoke of Non-Road Diesel Mobile Machinery (GB36886-2018). Meanwhile, Jinhua's relevant departments will strengthen the supervision and inspection of construction machinery working in prohibited areas, especially in autumn and winter. The rate of random monthly inspections will exceed 50%.
In the field of energy, Jinhua will eliminate 35 t/h coal-fired steam boilers, transform gas-fired boilers to reduce NOx emission, raise the standards for exhaust gas of biomass boilers in the construction area, and investigate and order the rectification of industrial kilns.
In the industrial field, 11 industrial parks at or above the provincial level have introduced their rectification plans, and 50% of the rectification tasks will be completed in 2019. By the end of October, 100 projects involving volatile organic compounds will reduce their emissions, and 1000 enterprises with unqualified gas emissions will be controlled. A long-term regulatory mechanism will be established for industries with regional characteristics, such as mahogany in Dongyang and hardware painting in Yongkang and Wuyi. The government will also pay close attention to newly approved and registered enterprises in order to prevent new problems. (By Chen Yuedan, translated by Jin Haiqiong, edited by Kendra Fiddler)
