4.1.4 the height of the exhaust funnel discharging phosgene, hydrogen cyanide and chlorine shall not be less than 25m, and the height of other exhaust funnels shall not be less than 15m (except for safety considerations or special process requirements). The specific height and the relative height relationship with the surrounding buildings shall be determined according to the environmental impact assessment documents. When the exhaust funnel of the new pollution source must be less than 15m, the maximum allowable discharge rate shall be 50% of the discharge rate limit listed in Table 1

4.1.5 if there are multiple exhaust funnels discharging the same pollutant in the pollutant discharge unit, if the distance between the two exhaust funnels is less than the sum of their geometric heights, they shall be combined as one equivalent exhaust funnels. If there are more than three short-distance exhaust stacks, and all of them discharge the same pollutant, the equivalent value of the first two exhaust stacks shall be obtained with the third and fourth exhaust stacks in turn. The pollutant emission rate of equivalent exhaust funnel shall be calculated according to formula (1):

4.1.6 when the exhaust gas with different emission control requirements is discharged from the combined exhaust funnel, it shall be monitored before the exhaust gas is mixed, and the corresponding emission control requirements shall be implemented; If the optional monitoring location can only monitor the mixed exhaust gas, it shall be implemented in accordance with the most stringent provisions of the emission control requirements

4.1.7 production process equipment, waste gas collection system and waste gas treatment facilities shall operate synchronously. In case of failure or maintenance of waste gas collection system or waste gas treatment facilities, the corresponding production process equipment shall be stopped and put into use after maintenance. If the production process equipment cannot be stopped or cannot be stopped in time due to safety and other factors, exhaust gas emergency treatment facilities shall be set or other alternative measures shall be taken

4.2 unorganized emission control requirements

4.2.1 from the date of implementation of the standard, the unorganized emission limits of VOCs in the plant area of new pollution sources and existing pollution sources shall comply with the requirements in Table 2
