Guangdong VOCs prevention and control up
On June 28th, the Guangdong Provincial Environmental Protection Department announced the “Regulations on the Remediation and Reduction of Volatile Organic Compounds (VOCs) in Guangdong Province (2018-2020)” (hereinafter referred to as the “Program”), clearly stating that by 2020, it will be basically completed. VOCs refined control and management system; the total emission of active VOCs in the province is reduced by more than 387,500 tons compared with 2015, and the area of the Pearl River Delta and Guangdong North and West is reduced by 276,600 tons and 111,900 tons respectively; the focus of active VOCs in the province The project has reduced emissions by more than 21.17 million tons, and the Pearl River Delta region and the eastern and western regions of Guangdong have reduced emissions by 167,300 tons and 44,400 tons respectively.
Background: Ozone is the primary air pollutant
According to the monitoring data, the average number of air quality standards in Guangdong in 2017 was 89.4%, the main pollutants were ozone (50.0% of the primary pollutants), and the annual evaluation concentration increased by 10.9%. In the first five months of this year, the primary pollutant was ozone, with an average concentration of 149 μg/m3, up 0.7% year-on-year.
“Since last year, the province’s air quality compliance rate has decreased. The key factor is ozone, with a contribution rate of 42.7%, followed by PM2.5, accounting for 39.3%. Ozone surpasses PM2.5 to become the province’s primary pollutant.” Guangdong Province According to experts from the Environmental Monitoring Center, the problem of ozone pollution in Guangdong has become increasingly prominent. The proportion of ozone as the primary pollutant in Chaozhou, Shanwei, Shantou and Zhanjiang City is more than 70%. Observing the data from 2013 to 2017, the proportion of ozone in the air pollutants of the province and the Pearl River Delta is increasing year by year, and the increase in 2017 is 3.1 and 5.1 percentage points compared with 2015, starting from 2015. Ozone has surpassed PM2.5 to become the primary pollutant of air pollution in Guangdong.
“Guangdong should put ozone and PM2.5 synergistic control into the atmospheric management agenda as soon as possible to solve the 'last mile' problem.” In order to accelerate the prevention and control of ozone pollution, the Provincial Environmental Protection Department recently organized an expert consultation on special actions for ozone pollution prevention and control. At the meeting, many well-known experts from the industry were invited to take measures for Guangdong's ozone pollution control. Academician Zhang Yuanhang of Peking University pointed out that the coordinated reduction of VOCs and nitrogen oxides (NOx) can effectively prevent and control ozone pollution. The joint control and cross-regional coordinated control of the Pearl River Delta Dawan District is the key to the prevention and control of air pollution in Guangdong."
Under the strategic plan of the country to win the blue sky defense war, the national pollution reduction efforts are unprecedented. Zhang Yuanhang believes that while firmly grasping this external condition, Guangdong should make full use of the construction of Guangdong, Hong Kong and Macao Dawan District to release energy structure and industry. The potential of structural adjustment in pollution reduction. It is necessary to take ozone and PM2.5 as the core, and adopt multi-pollutant coordinated control and cross-regional joint prevention and control to further improve regional air quality.
“I propose to officially launch the Guangdong Ozone Pollution Prevention and Control Action Plan.” Professor Shao Min of Jinan University proposed to set up an ozone prevention and control special action inspection team and improve the typical industry by establishing a list of scattered pollution enterprises and a list of key industry enterprises and parks. Supervision guidelines, follow-up assessment and other methods to strengthen the province's VOC emissions control, improve air quality compliance rate.
Under this background, the Provincial Environmental Protection Department, in conjunction with the Provincial Development and Reform Commission, the Provincial Department of Finance, the Provincial Department of Transportation, and the Provincial Quality Supervision Bureau, jointly issued the “Program” to provide top-level design for VOCs prevention and control.
Idea: Strictly control new additions, focus on key areas and urban emission reduction work
In order to do a good job in the prevention and control of ozone pollution in the province and win the battle against blue sky, the "Proposal" proposes to strengthen the adjustment of industrial structure, deepen the emission reduction of fixed source VOCs, comprehensively promote the reduction of mobile source VOCs, and orderly reduce the VOCs of non-point sources. Five major tasks, including the establishment of a sound VOCs emission management system and the comprehensive improvement of the VOCs regulatory capacity system, and 19 specific measures.
"The basic ideas of the "Program" are two. One is to strictly control the emission control of VOCs, and the other is to reduce the emission reduction of VOCs in key areas and key cities." The person in charge of the Provincial Environmental Protection Department said that according to the design of the idea, the "plan" According to the policy of “digestion increment, reduction of stocks, total amount of control”, whether VOCs emissions meet the total control requirements is the pre-condition for EIA approval, and is included in the discharge permit management according to law, and the construction projects for emission VOCs are implemented within the region. Substitution of reductions to promote the replacement of raw and auxiliary materials and process technology upgrades for low (no) VOCs.
The Pearl River Delta region, where ozone pollution is more prominent, is listed as a key area for VOCs emission reduction in the province; Guangzhou, Shenzhen, Foshan, Dongguan, Maoming and Huizhou, which have large volatile organic emissions, are key cities for VOCs emission reduction. At the same time, we will focus on promoting the reduction of VOCs in key industries such as refining and petrochemical, chemical, industrial coating, printing, shoemaking, and electronics manufacturing, as well as the storage and marketing of motor vehicles and oil products; Reduction of key active components of VOCs such as alkynes, aldehydes and ketones.
The "Proposal" also proposed to increase the intensity of industrial restructuring. Each city shall formulate a special plan for “scattering and pollution” enterprises, establish a list of “disorganized pollution” air pollution discharge enterprises within the jurisdiction, and clarify the remediation measures and time limits for remediation. Before the end of 2019, the cities should complete the clean-up and rectification of VOCs “scattering and pollution” enterprises in accordance with the law. In terms of access to construction projects, it is necessary to strictly limit the construction projects of high VOCs such as petrochemical, chemical, packaging and printing, industrial coating, etc. In the key industries, new industrial enterprises involved in VOCs emission should enter the park in principle and are not included in the planning of petrochemical industry. The new refining and chemical project of the Plan shall not be constructed.
In terms of emission reduction of fixed-source VOCs, it is necessary to comprehensively promote the comprehensive management of VOCs in the petroleum and chemical industries. By 2020, the emissions of VOCs in the chemical industry such as pharmaceuticals, synthetic resins, rubber and plastic products manufacturing will be reduced by more than 30%. Focus on promoting VOCs emission control in the coating process of container, automobile, furniture, shipbuilding and other manufacturing industries. By 2020, the province's industrial coating VOCs emissions will be reduced by more than 20%.
In terms of emission reduction of mobile source VOCs, we will focus on gasoline vehicle exhaust emissions and evaporative emission control to promote the reduction of vehicle VOCs. The Pearl River Delta region is striving to implement the national VI emission standards for motor vehicles in 2018. The province will implement the light vehicle national VI emission standard from July 1, 2020, and introduce on-board oil and gas recovery technology (ORVR) to significantly reduce evaporative emissions.
A key link in the prevention and control of VOCs is source reduction. In this regard, the “Program” requires the promotion of raw materials and products with low VOCs content and low reactivity. Raw material substitution is implemented with a focus on reducing the use of solvents and auxiliaries such as benzene, toluene, xylene, and dimethylformamide. The coatings industry focuses on the promotion of green products such as water-based coatings, powder coatings, high-solids coatings, and radiation-curing coatings.
Measures: find out the family, strengthen supervision and inspection
In order to ensure the implementation of the work, the "Proposal" requires accelerating the construction of the province's comprehensive management platform for VOCs emission control and the accounts of VOCs in various cities, systematically grasping the production, processing, emission and distribution of industrial source VOCs, and uniformly supervising the pollution of VOCs. Material emissions and online automatic monitoring data.
Before the end of 2018, the cities and municipalities completed the investigation and inventory preparation of VOCs pollution sources in their respective jurisdictions, reported the list of key projects to the provincial Environmental Protection Department, and established a mechanism to update the VOCs emission inventory.
“Regular inspections of VOCs in key enterprises will be carried out regularly, and enterprises that do not meet the relevant regulations and fail to meet the standards for discharge or idle treatment facilities shall be investigated and punished according to law.” The person in charge of the Environmental Protection Bureau of the Provincial Environmental Protection Department said that law enforcement personnel should be regularly organized in various places. Conduct business training to improve the law enforcement level of law enforcement personnel; improve the front-end mobile law enforcement terminal equipment and back-office mobile law enforcement business management support system for law enforcement personnel, and improve environmental violations such as the smuggling of corporate air pollutants and the suspension of pollution control facilities. Supervise the effectiveness of law enforcement. Enterprises should also standardize internal environmental management systems, formulate operational management plans for VOCs prevention and control facilities, and keep relevant account records for at least three years.
"To establish a VOCs pollution reduction scheduling, notification and early warning system, regularly schedule the completion of key projects, and implement the notification of the construction of key projects that are lagging behind and the implementation of policy measures are not in place." The person in charge of the Provincial Environmental Protection Department mentioned that The "Proposal" proposes to introduce a third-party evaluation and assessment mechanism, carry out supervision and inspection and spot checks on the key project management of VOCs, and carry out assessment and assessment of the implementation of the program year by year, and the results of the assessment are included in the annual air pollution prevention and control assessment. “Interview with local people’s governments that have not completed the annual air quality improvement and VOCs emission reduction targets.”
The "Proposal" also mentioned that it is necessary to formulate and introduce comprehensive rectification regulations for VOCs and refine the management requirements of VOCs in various fields. Accelerate the formulation of emission standards for volatile organic compounds in key industries such as catering fumes and shipbuilding, and mandatory environmental standards for VOCs in organic solvents such as paints, inks, adhesives and cleaning agents. We will improve technical specifications, technical guidelines, and clean production audit technical standards for the prevention and control of volatile organic compounds in key industries, and continuously improve the local VOCs pollution prevention and control standards system. All localities can, in conjunction with provincial standards and regulations, formulate localized VOCs for industrial industry. (Environment Magazine)
