The project assisted EPA to implement regulations and related planning work of VOCs control. These include fours highlighted work: to amend VOCs rules to petrochemical, semiconductor, TFT-LCD, and adhesive tape industries; to establish the selection criteria for HAP calculation and to complete HAP calculation programs in 5 industries; to study the US area source inventory system and to do some domestic survey work and give control measure suggestions in pesticide and consumer product categorized industries; to hold 10 meeting about emission inventory survey and related integration works to wastewater treatment plants. The chief achievements for this project are: 1. By adopting the amended 4 relevant rules, under this project estimation there will be 17,686 tons emission reduction and 0.61% enhancement of average ozone concentration by using the air quality modeling system built in 2002; 2. By referring to the US emission factors from illustrative data and current VOCs emission registry records, the project took the environmental threshold limit values into account, calculated the emissions of toxic air pollutants in the TFT-LCD, semiconductor, automotive coating, adhesive tape, and petrochemical industries, estimated the toxic intensity, and finally concluded the suggested prior control pollutant- styrene, formaldehyde, propanol, m/p- xylene, isopropanol, toluene, and dichloromethane - to the future regulation; 3. The project planned the framework of VOCs control in area source from US experiences. In addition, by considering the administrative feasibility, cost-effectiveness, and technical feasibility, it also provided the prior regulated categories after finishing control measures assessment in pesticides, consumer products, and building coating; 4. The project improved the accuracy of emission inventory and established the survey process to area source and wastewater treatment plant pollutants
