This standard specifies the required sanitary protection distance between internal combustion engine plants and residential areas. This standard applies to new internal combustion engine plants located in plains and hilly areas, as well as the expansion and reconstruction of existing internal combustion engine plants. Existing internal combustion engine plants can refer to this standard for implementation. The sanitary protection distance in areas with complex terrain conditions should be determined jointly by the competent department of the construction unit and the health and environmental protection authorities of the municipality or autonomous region where the construction project is located based on the atmospheric environment quality evaluation report.

All technical contents of this standard are mandatory.
The standard for the sanitary protection distance of industrial enterprises is a comprehensive standard involving construction planning, general layout of industrial construction, environmental sanitation, and sanitary engineering. Its purpose is to ensure that the pollutants generated after the commissioning of national key industrial enterprises will not affect the health of people in residential areas. This standard aims at the characteristics of various harmful factors, finds out the occurrence, diffusion, dilution, attenuation, and degradation characteristics of harmful factors, and then determines the allowable emission intensity of industrial enterprises based on the best practical technical principles, that is, the governance measures and maintenance management measures that can be achieved according to my country's current economic level. Finally, the appropriate gas diffusion model and corresponding parameters are selected to determine the required sanitary protection distance. This standard will be implemented from January 1, 200.

Health protection zone standard for internal combustion engine plant
Health protection zone standard for internal combustion engine plant This standard specifies the required health protection distance between internal combustion engine plant and residential area. GB 18074 2000
This standard is applicable to new internal combustion engine plant located in plain and hilly areas and the expansion and reconstruction projects of existing internal combustion engine plant. Existing internal combustion engine plant can refer to it for implementation. The dust protection distance in complex terrain conditions shall be determined by the competent department of the construction unit and the health and environmental protection departments of the province, municipality and autonomous region where the construction project is located based on the atmospheric environment quality assessment report. 2 Definitions
This standard adopts the following definitions.
2.1 Health protection zone The minimum distance from the boundary of the department (workshop or section) producing harmful factors to the boundary of the residential area. 3 Standard Contents www.bzxz.net
3.1 The sanitary protection distance of the internal combustion engine plant is stipulated according to the average wind speed in the area in the past five years as shown in Table 1. Table 1
Violation m/s
Height, m ​​
3.2 This standard also stipulates that the location of the internal combustion engine plant and the residential area should take into account the influence of factors such as wind direction frequency and terrain to minimize the pollution of the residential area's atmospheric environment.
Approved by the State Administration of Quality and Technical Supervision on April 10, 2000 and implemented on January 1, 2001
