During this plan, the accomplishment of operation and maintenance for all air quality monitoring sites includes 192 times of weekly maintenances, 96 time of double weeks maintenances, 48 times of monthly maintenances, 16 times of quarter maintenances, and 4 times of yearly maintenances for automatic monitoring sites; 84 times of operation and maintenance, 168 times of sampling and analysis-TSP (PM10), 84 times of sampling and analysis-dust gauge for manual monitoring sites which include replacing a manual monitoring site, a total hydrocarbon analyzer(THC), and a hydrogen generator. Monthly meetings have continued to make improvement for the quality of the maintenance. The QA works of the site were executed 4 times of the functional inspection and the yearly inspection by third party, all lacks have been completed the correction to make sites to proceed the work smoothly and the prevention has been built to avoid any failures. The available rates of average annual data are Ne-Li Site as 98.93%; Shin-Shing Site as 99.16%; San-Ming Site as 98.74%; Guan-In Site as 99.33%. The statistical analysis has demonstrated that each site measured the value was equal to the typical monitoring features; transportation source has main species of pollutants such as CO, NOx have highest values in San-Ming Site. The stationary source pollutant possibly receives emissions from industrial zones which influenced the measured value of SO2 in Guan-In Site of Guan-In Industrial Zone and the value was obviously higher than other sites. For the pollution of ambient air regions, O3, PM10 and PM2.5 are close to the tendency of concentration in every site. Manual monitoring sites have been operated and maintained regularly in the month of first half and the month of second half; also, the report must be submitted in every next month of 15th. This plan has been executed to achieve the 100% availability ratio for all instruments. In this year, the result of TSP monitoring was complied with the air quality standard of 24 hours value (250 μg/m3) such as TSP, sulfates, nitrates and chloride are the closer tendency for all sites.
