Follow the framework of preliminary project, this project continues to analyze on 3 parts: to prepare the instrument of HAPs control of stationary sources, to analyze ambient levels for HAPs, and to develop the VOCs control tool for coating/paint and consumer products. During the project period, the drafts of emission standards for HAPs of stationary sources have been revised. Three regulations that related with HAPs control have established in accordance with the Air Pollution Act. The investigation of vinyl chloride and polyvinyl chloride manufacturer (7 factories, 10 processes) has completed to investigate the compliance and improvement. The HAPs emissions and control technology floor of vehicle body and parts, tape, and polyurethane synthetic leather manufacturing have completed, the draft regulatory and emission standard amendments are also proposed. For gas station VOCs control, we analyzed the BTEX ambient concentration around 10 gas stations. In order to understand the influence from fugitive sources at gas station, the tests to perform the function of the vacuum pressure valve, and refueling gun with or without hood have been conducted in this project, the diffidence of total VOCs concentration between self-service refueling and refueling by employee are also test. On the control tools of stationary sources, three draft amendments related to management and calculation for the reporting of emissions have proposed. The air toxics emission factors of boiler power generation process have calculated by follow the process that established by US EPA. The maximum ground level concentration modelling tool for HAPs (personal computer version) has been modified based on testers’ comments. The monitoring data of the special industrial parks of the year 2016 to 2018, and the ambient concentrations of organic air toxics from photochemical monitoring stations, and heavy metal, dioxins from monitoring projects were analyzed. For coating volatile organic matter control operations, collect technical information on low VOCs in coatings. Hair cosmetics and liquid cleaners were suggested as the items to do survey for VOCs content of consumer products.
