This plan mainly executed the maintenance service of Tainan Air Quality Monitoring Display System to make sure the equipments’ normal operation and the data quality y, it also collected the entire service log sheet and the improvement suggestions provided to the Tainan Environmental Protection Bureau (EPB) 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 Central Environmental Administration Bureau.
The achievement of this project is stated below:
First, Chencily Auto-Monitoring Station
(1) Monitoring Station’s operation and maintenance
Regular Maintenance included weekly maintenance (48 times), monthly maintenance (12 times), and quarterly maintenance (4 times), and half-yearly maintenance (2 times) and yearly maintenance (1 time), all works based on this plan schedule to carry on and all equipments in the execution period led to achieve 100% properly. Quarterly maintenance in analyzers’ of multi-spot calibration result shown in table 1, its correlation coefficient all above 0.995, the slope all between 0.95~1.01, the intercept was between ±2%F.S., conformed to the Quality Check of survey Air Monitoring Standard.
(2) Data Management
All the data acquisition rate of all analyzers was all above 98%, the meteorological equipments were above 99%.
(3) Quality Control Process
1. AQMP invited the experts to conduct the quality control process
It was based on AQMP plan from July 14th of 2010 and appointed Professor Wu,Yi-Ling of National Chengkung University to carry on sites quality check including Chencily Auto-Monitoring Station, Shiehchin Primary School Manual Station and Chongshan Secondary School Manual Station. All related quality check results were revised and confirmed in the sites.
2. The Environmental Protection Administration Local Stations Survey
The Environmental Protection Administration conducted Chencily Auto-Monitoring Station Survey on July 21st 2010 to do the quality check and the assessment result was fine.
3. Quality Assurance Check
The team work conducted the quality assurance check yearly on March 17th 2011 and the result was satisfactory.
(4) Explanation of monitoring result
Chencily Auto-Monitoring Station showed 1 episode day (O3 counted for 1 episode day); Annan station showed 7 episode days (O3 counted for 2 episode days and PM10 counted for 5 episode days); Tainan station showed 7 episode days (O3 counted for 5 episode days and PM10 counted for 2 episode days); however, in the rest good days’ percentage, Chencily Auto-Monitoring Station obviously showed better data than the other two stations.
Second, Xiaosimeng information electronic monitoring system
(1) Regular line inspection and environment clean check
Various months’ inspection frequency was all above 4 times.
(2) Information electronic display renewal operation
This plan in the execution period did 278 times advertisements in which the EPB took 117 times all together, the proportion accounted for 42.09%.
Third, the manual monitoring station
There were following stations including EPB, Mingde Secondary School, Shiehchin
Primary School, Chongshan Secondary School, Anping Waste Water Factory, South Administration Office stations.
(1) Monitoring station operation maintenance
It had to conduct the first half and second half monthly regular service and maintenance job and on 10th in next month to submit the report and make sure all various equipments led to 100% properly.
(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 (99/06/10, 99/09/10, 99/12/10, 100/03/07) showed in Table 2, each error was between ±5%, and the R value was bigger than 0.995. Every half year conducted primary standard calibration (99/06/09, 99/12/07) the R value was 0.9999. All the calibration result in this plan met the code requirement.
(3) Monitoring result
In this year TSP monitoring result from June 2010 to May 2011, were complied with the air quality standard 24 hourly value (250 μg/m3). All previous years (from 2006 to 2010) this city TSP monitoring result showed that consistent tendency, presented the winter was high and the summer was low. The year 2010 data showed it was lowest compared with all previous years.
In the dust fall quantity monitoring part, from June 2010 to May 2011, each manual station classified as the extremely slight pollution class. All previous years from 2006 to 2010 each station dust fall demonstrated that year 2009 average values were the lowest within the past 5 years. However, in year 2011 from January to May’s dust fall were also somewhat low and closed to the first 5 month average measured value in year 2009.
(3) Accuracy test
This plan completed 6 manual stations for the accuracy quarterly tests in which all the present stage did 12 times parallel sampling work and the whole error percentage was between - 8.05% to 8.02%, meets the erroneous within 10% requirement.
(Five) The particulate matter’s sampling in the air quality deterioration season
The first sampling time from December 23rd to 24th in year 2010 were carried in Tainan and Annan stations (4 samples) and the second sampling time from February 27th to 28th in year 2011 were carried in Tainan station (6 samples).
The Annan station’s night time PM10 concentration and TC were slightly higher than day time but water-soluble ion and element proportion made no obvious difference. The Tainan station’s night time PM10 concentration and TC were higher than day time, water-soluble ion and element proportion made no obvious difference.
Fifth, the educational guidance arrangement
In this plan, it had to hold the educational guidance arrangement in the campus together with the mobile monitoring van demonstration. The purpose was to let students to understand air pollution concept and the importance of the air quality monitoring. Various arrangements listed below:
(1) First run: It was held on April 1st 2011 at Tainan Shiaigong Primary School.
(2) Second run: It was held on April 12th 2011 at Tainan Kungyuan Primary School.
Sixth, the guidance animation, the coloring doodle, the electronic greeting card and the small game
Based on the contract, this plan had to complete one of below working items including the guidance animation, the coloring doodle, the electronic greeting card and the environmental protection games. Pls also refer to below table 3 the comprehensive chart of achieving rate of each assigned project
