Article 44 and Item 4 of Article 56 of the Law of the People's Republic of China on the Prevention and Control of Air Pollution stipulate that operators of urban catering services must take measures to prevent the pollution caused by oil fume to the living environment of nearby residents. Offenders shall be ordered by the competent administrative department of environmental protection of the local people's government at or above the county level or other departments exercising supervision and management according to law to stop the illegal act, make corrections within a time limit, and may be fined up to 51,111 yuan. Whether it causes pollution can be judged from whether an oil fume purification device is installed and whether the oil fume emission meets the "Cooking fume emission standard". It can be seen that the competent department of oil fume pollution should be the environmental protection department.

at the same time, the specific situation should also be analyzed in detail. if the hotel does not have an industrial and commercial business license at all and is operating without a license, the industrial and commercial department should first ban it, which will be faster to deal with. For the specific terms, see Article 4 of the Measures for Investigating and Banning Unlicensed Business.

according to the above two laws and regulations, if it is unlicensed, both departments should accept the complaint, and whoever fails to accept it will be regarded as an administrative omission. refer to the regulations on letters and visits in the State Council, which department does not accept the written document of rejection, and then administrative reconsideration or litigation can be done. If it is a certified hotel, it must be handled by the environmental protection department.
