This plan mainly executed the maintenance service of Tainan Air Quality Monitoring Display System to make sure the normal operation and the data quality for equipment, it also collected the log sheet of entire service and the improved suggestions provided to the Tainan Environmental Protection Bureau (EPB) to realize the service conditions. Further to this, it offered revised standard of operational procedure and the maintenance test to guarantee the maintenance quality and met the inspection monitoring station assessment criteria from Environmental Protection Administration (EPA). Plan of Timeframe：From 5th July, 2014 to 4th July, 2015. The achievement of this project is stated below: First, the manual monitoring station (1) Operation and maintenance in monitoring station It had to conduct the regular service and maintenance in every beginning of the month and end of the month. For the next month, submitting the report and make sure all various equipment led to 100% proper ratio before the month of 10th. (2) Calibration Process For single point check before and after sampling, the flow should be between 40 to 60 CFM and the error was between ±7%. For quarterly multi-spot calibration (2014/7.10., 2015/01.04), each error was between ±5%, and the R value was bigger than 0.995. Every half year has been conducted primary standard calibration (2014/7/5, 2015/1/3) the R value was 0.999. All the calibration results in this plan have been met the regulation. (3) Sampling and inspection ＆ analysis TSP analysis of twice a month, PM10, PM2.5 and dust content of once a month, plans are in progress implementing the provisions of the contract. Second, Automatic Station (1) Monitoring Station’s operation and maintenance Regular Maintenance included weekly maintenance, monthly maintenance, and quarterly maintenance, and half-yearly maintenance and yearly maintenance, all works based on this plan schedule to carry on and all equipment in the execution period led to achieve 100% proper ratio. (2) Calibration Process Quarterly maintenance in analyzers of multi-spot calibration, it’s correlation coefficient were all above 0.995, slopes were all between 0.88~1.12, intercepts were between ±2%F.S., conformed to the Quality Check of Air Quality Monitoring Standard. Third, Xiaosimeng information electronic monitoring system (1) Regular inspection and environmental clean Every inspection is above 1 time per 1 month. (2) Update of the display board This plan in the execution period with 255 times advertisements was including the EPB had 84 times. Forth, Monitoring result (1) The manual monitoring station In this year, TSP monitoring result from July 2014 to June 2015, were complied with 24 hourly value (250 μg/m3) of the air quality standard. All previous monitoring result showed that consistent tendency, presented the winter was higher values and the summer was lower values. In monthly average, the highest value was highest in February 2015, and the lowest value was in September 2014. Maximum ratio of analysis is SO42- and NO3- and Cl- and Pb. In the portion of dust fall, each manual station classified as the extremely slight pollution class. All previous years which are dust fall demonstrated that reducing the measured values. In monthly average, the highest value was in September 2015 and the lowest value was in April 2014. For monthly average value of PM10 station, the highest average value which is 105 μg/m3, the lowest value which is 24 μg/m3. For monthly average value of PM2.5 station, the highest average value which is 59 μg/m3, the lowest value which is 12 μg/m3. In PM2.5 and PM10 ratios, the range of manual stations is between 0.32 to 0.82, and the range of automatic stations is between 0.23 to 0.70. Both of values have slight difference. In addition, for the overall average, the manual station is 0.51 and the automatic station is 0.48, so the manual station is relatively higher which is considering the difference between the manual station and the automatic station regarding analysis theory. Thus, the result of comparison is for the reference. (2) Automatic Station In Tainan, six Automatic Monitoring Station showed result from July 2014 to June 2015, that consistent tendency, presented the winter was higher values and the summer was lower values. In PM10 and O3, the season was changed obviously. Air Quality Standard: Comparing with PSI index and Air Quality Standard in the ozone portion. The Sinying station and Shanhau station have been influenced mainly by PM10. The Annan station and Tainan station have been influenced mainly by PM10 and O3. Heavy concentration of PM10 in winter and spring, heavy O3 concentration in spring and autumn, and heavy concentration of PM10 and O3 in autumn should be paid attention to air quality changes.
