The amendment of Clean Air Act in 1999 has adapted the graded Control Region system, from which each city and county is classified according to the average concentration of air pollutants and air pollution standards. Class 1 control regions include areas national parks and natural protected areas; Class 2 control regions means areas that meet air quality standards; whereas, Class 3 control regions means areas that do not meet air quality standards. In 2016, all cities and counties south of Yunlin County were rated as Class 3 for PM10, while Kaohsiung and Pingtung were rated as C ass 3 for O3. As for PM2.5 all cities/counties other than Taitung County were rated as Class 3, indicating that the control of PM2.5 will be our future objective. On the other hand, the 8-hour average of O3 has taken into the calculation of the AQI, therefore, the focus of O3 control has shifted to the decrease of the number of red-alert days. This project has been continuous for many years and has three main tasks: I. Sharing of air pollution control strategies The Clean Air Action Plant of 2015 has indicated the emission of PM, SOx, NOx, and VOCs (collectively as PSNV) should be reduced by 33%, 41%, 47%, and 14% respectively, with 2010 as the base year, to achieve Air Quality Standards. According to the Stationary Emission Database, until 2016 SOx and NOx have decreased by 35% and 19% respectively, indicating more reduction measures should be made. PM and VOCs are estimated by the emission coefficient, which is the average value of the proces. Therefore, the air quality analysis is used to improve the countermeasures. II. Control of petrochemical industry emissions This year the control of petrochemical industry emissions focuses on 1. Further control of flare towers after the discovery of ozone increase due to the emission of ethylene and propylene; 2. The compilation of pollution map with FTIR monitoring in petrochemical industrial zones after the Chaoliu Incidence; 3. Tracing and reduction of HAPs emission after the promulgation of stationary HAPs standards and make suggestions to the adjustment of VOCs Standards accordingly. III. Control of Stationary PM2.5 emission This year the measures to control PM2.5 emission includes 1. Control of major firepower plants; 2. Control of small boilers; and 3. Tracing of compliances after the promulgation of Power Generation Facilities Emission Standards in 2014.
