Shizuishan City strengthens summer ozone control

Since June 2020, ozone pollution in Shizuishan City has become prominent, with a gradual increase in trend. As of June 30, the average ozone concentration was 148 micrograms/cubic meter, an increase of 5% year-on-year. The number of pollution days with ozone as the main pollutant reached 8 days, an increase of 5 days. In response to the unfavorable situation at that time, our Office specially formulated the "Ten Ozone Control Articles" based on the "Special Action Plan for the Prevention and Control of Ozone Pollution in 2020 by the Autonomous Region" and the actual situation. The specific measures are as follows:

　　 Ⅰ. Management of VOCs-related enterprises

　　 1. In accordance with the "Regulations on the Control of Volatile Organic Compounds Undisposed Emissions", accelerate the promotion of non-scheduled emissions management and control operations. The main point is to carry out the storage, transfer and transportation of materials containing VOCs (including raw and auxiliary materials containing VOCs, products containing VOCs, waste materials containing VOCs, and organic polymers, etc.), leakage of equipment and pipeline components, opening of liquid surface escaping and Check and rectify the non-scheduled discharge links in the process.

　　 2. If the sealing points of equipment and pipeline components containing gaseous and liquid VOCs are greater than or equal to 2,000, a round of leak detection and correction (LDAR) operation shall be completed by July 20, and the leak source shall be corrected in time.

　　 Ⅱ, industrial enterprises peak production

Intensify the seasonal control of industrial enterprises' production. According to the requirements of the "Announcement on Staggering Production of Some Industrial Occupations in the Summer of 2020" (Shigong Xinfa [2020] No. 100), the main points will be coke, activated carbon, chemical raw materials and chemical products. Production, oil refining and chemical, pharmaceutical, pesticide intermediate production, carbon enterprises with carbon brick production, ferroalloy enterprises with inadequate and stable emissions in the tail gas power generation section, and cement, steel and coking enterprises with inadequate and qualified emissions are classified as staggered production. Guide enterprises to reasonably arrange production schedules and reduce the impact on ambient air quality.

　　 III. Oil Storage, Transportation and Sales Control

1. Intensify the “look back” efforts of oil and gas recovery in gas stations, oil depots and tank trucks, especially at gas stations (points) along suburban national roads and provincial roads in the city, and focus on problem rectification and strictly implement ozone Pollution prevention and control measures. From June to September, the fueling and unloading operations in the built-up area should be staggered during the high temperature period, and the oil unloading operation should be suspended from 11:00 to 17:00; in any case, the gasoline station and the oil depot should not cause gasoline leakage due to operation, maintenance and management. . Before July 15, the oil storage depot conducted a test on the closed collection system of oil and gas, and the concentration of the volume fraction of oil and gas discharged from any leakage point should not exceed 0.05%.

2. Strengthen the quality supervision and management of oil production and sales units, severely crack down on the production, processing, and sales of unqualified oil products and vehicle urea, continue to carry out sampling inspections of vehicle oil quality in the production and circulation fields, and promptly announce the results of oil quality sampling . The unqualified oil products found in the inspection shall be confiscated and the history shall be checked to strictly punish the illegal acts. Implementation of black gas station (point) dynamic clearing.

　　 Ⅳ, professional management of auto repair

　　 Strict auto repair pollution prevention and control. During the period of ozone prevention and control, strengthen the management and control of auto repair enterprises that are open-type, not rectified in place, have no waste gas collection and treatment facilities or have abnormal operation of facilities. Auto repair professional paint spraying operation (in addition to adopting efficient management processes such as adsorption concentration-catalytic incineration and equipment VOCs on-line monitoring and overrun alarm equipment) to perform the wrong time operation, the paint spraying operation is suspended from 11:00 to 17:00.

　　 VI. Construction area source control

　　 1. Strengthen the supervision of municipal construction such as construction and decoration, road painting operations, and asphalt paving. From June to September, minimize the application of organic solvents such as asphalt pavement, marking, pipelines, railing spraying on municipal roads. During the daytime high temperature period, field-related VOCs such as asphalt pavement, scribing, piping, railing spraying, etc. were suspended. Suspend the construction of field-related VOCs such as wall painting and steel structure painting.

2. Carry out on-site inspections of urban road asphalt pavement projects from time to time to ensure that asphalt pavement is staggered from 11:00 to 16:00 daily during high temperature and intense sunshine periods, and the monitoring and inspection found that the requirements of the "Special Action Plan for the Prevention of Ozone Pollution in the Autonomous Region in 2020" have not been implemented Problems, promptly notify the relevant units to supervise, and pay close attention to the implementation of rectification.
