The largest number of VOC emission sources, 50, were checked in this year. This included the number of feedstock, products, fuels and pollutants. This project established a pollutant check list SOP for restaurants and set up a database of 205 restaurants. Five surface coating factories were selected for hood suction efficiency assessments. We found that without pipe cleansing maintenance hood suction efficiency decreased. According to the emission database 238.538 MT VOCs came from petrochemicals and 193.33 MT VOCs came from petrol stations. Restaurant emissions were 203MT TSP, 195MT PM10, 68MT THC and 378MT NMHC. It was found that 124.414MT VOCs were reduced from the largest 20 VOC emission sources. This project tested A/L of 108 petrol stations and obtained 97.6% qualified and tested 2 inch WC static pressure performance in vapor recovery system dispensing facilities with 50% qualified. There were 2040 sources from which volatile organic compounds leaked below 1000 ppm. The THC concentration in the emissions from 5 stationary sources were qualified. In this year, according to our suggestions, 10 VOC emission sources improved their pollution control systems.
