Summary of common environmental violations related to exhaust emissions

01. When the exhaust gas is collected by an external exhaust hood (gas collecting hood), the control wind speed does not reach 0.3m/s at the unorganized emission position of VOCs farthest from the opening surface of the exhaust hood (if there are specific provisions in the relevant industrial specifications, the relevant provisions shall prevail).

Applicable penalty provisions: Item 1 of Article 108 of the Law of the People's Republic of China on the Prevention and Control of Air Pollution: Anyone who violates the provisions of this Law and commits one of the following acts shall be ordered to make corrections by the competent department of ecological environment of the people's government at or above the county level and be fined not less than 20000 yuan but not more than 200000 yuan; If it refuses to make corrections, it shall be ordered to stop production for rectification: (1) The production and service activities that produce waste gas containing volatile organic compounds are not carried out in the confined space or equipment, and the pollution prevention and control facilities are not installed and used in accordance with the provisions, or the measures to reduce waste gas emissions are not taken;

02. The transmission pipeline of the waste gas collection system is not under negative pressure, or the leakage detection value under positive pressure exceeds 500 μ mol/mol。

03. For VOCs leakage control of equipment and pipeline components, if one of the following conditions is found, it is illegal, and shall be dealt with in accordance with laws and regulations and other relevant provisions:

a) The number of enterprise sealing points exceeds 2000 (inclusive), but leakage detection and repair work has not been carried out;

b) Failing to detect and repair the leakage according to the specified frequency and time;

c) Through random spot check on the site, it is found that more than 2 (excluding) sealing points not within the repair period have visible leakage phenomenon or exceed the identified leakage concentration under the condition that no more than 100 sealing points are detected.

Whether the leakage detection and repair work is carried out according to the specified frequency and time shall be determined according to the account data.

04. VOCs treatment facilities are not configured as required (VOCs treatment facilities shall be configured when the initial emission rate of non-methane total hydrocarbon in the collected waste gas is ≥ 3kgh, and the treatment efficiency shall not be less than 80%; for key regions, VOCs treatment facilities shall be configured when the initial emission rate of non-methane total hydrocarbon in the collected waste gas is ≥ 2kgh, and the treatment efficiency shall not be less than 80%; except that the raw and auxiliary materials used meet the national regulations on products with low VOCs content)

05. The height of exhaust funnel is less than 15m (except for safety considerations or special process requirements), or the exhaust funnel is not built according to the environmental impact assessment document.

Applicable penalty provisions: Item 5 of Article 100 of the Law of the People's Republic of China on the Prevention and Control of Air Pollution: Anyone who violates the provisions of this Law and commits one of the following acts shall be ordered to make corrections by the competent department of ecological environment of the people's government at or above the county level and be fined not less than 20000 yuan but not more than 200000 yuan; Those who refuse to make corrections shall be ordered to stop production for rectification:...... (V) Those who fail to set up air pollutant discharge outlets according to regulations.

06. The VOCs waste gas collection and treatment system is not synchronized with the production process equipment. (In case of failure or maintenance of VOCs waste gas collection and treatment system, the corresponding production process equipment shall stop running and be put into use synchronously after the maintenance is completed; if the production process equipment cannot stop running or cannot stop running in time, the waste gas emergency treatment facilities shall be set up or other alternative measures shall be taken.)

At the same time, the case shall be transferred to the public security organ in accordance with Article 63 (3) of the Environmental Protection Law of the People's Republic of China: if an enterprise, institution or other producer or operator commits one of the following acts, which does not constitute a crime, in addition to being punished in accordance with relevant laws and regulations, the competent environmental protection department of the people's government at or above the county level or other relevant departments shall transfer the case to the public security organ, The person in charge and other persons directly responsible shall be detained for not less than 10 days but not more than 15 days; If the circumstances are relatively minor, they shall be detained for not less than five days but not more than ten days:...... (3) illegally discharging pollutants by means of concealed pipes, seepage wells, seepage pits, perfusion, or tampering with or falsifying monitoring data, or abnormal operation of pollution prevention and control facilities to avoid supervision;

07. Failure to establish a standing book as required to record the main operation and maintenance information of the waste gas collection system and VOCs treatment facilities, such as operation time, waste gas treatment capacity, operating temperature, residence time, adsorbent regeneration and replacement cycle and replacement amount, catalyst replacement cycle and replacement amount, pH value of adsorbed liquid and other key operating parameters.

Applicable penalty provisions: Article 69 of the Regulations on the Administration of Pollutant Discharge Permits (to be issued) [Violation of standing book records (penalty on a daily basis)], in violation of the provisions of this Regulation, commits one of the following acts, the local ecological and environmental authorities at or above the municipal level divided into districts shall order correction and impose a fine of not less than 1000 yuan but not more than 20000 yuan per day; If it refuses to make corrections, the administrative organ that has made the punishment decision according to law may, from the next day after the date of the order to make corrections, impose continuous punishment on a daily basis according to the original amount of punishment:

（1） Failure to record the account in accordance with the requirements of the pollution discharge license;

（2） The contents of the account are untrue and incomplete.

08. Discharge air pollutants in excess of the air pollutant discharge standard. The monitoring shall be conducted at the place 1m away from the discharge outlet of the plant doors and windows or vents, other openings (holes), and 1.5m above the ground. If the plant is incomplete (if there is a roof without a wall), the monitoring shall be carried out at the place 1m downwind from the operation station and 1.5m above the ground. Any hourly average concentration (6mg/m3) or any single concentration (20mg/m3) measured at the monitoring point in accordance with the requirements of the monitoring specification shall be determined as exceeding the limit value specified in this standard.

Applicable penalty provisions: Article 99, Item 2, of the Law of the People's Republic of China on the Prevention and Control of Air Pollution: order correction, restrict production, stop production for rectification, and impose a fine of not less than 100000 yuan but not more than 1 million yuan; If the circumstances are serious, it shall be ordered to suspend business or close down (2) Discharge of atmospheric pollutants in excess of the emission standards of atmospheric pollutants or the total emission control indicators of key atmospheric pollutants.
