This project was implemented from May. 4, 2010 to Mar. 3, 2011. All the tasks defined in the contract had been completed including the sampling analysis, maintenance of the Manual Operation Air Monitoring Stations, regular maintenance of Auto-Monitoring Stations, calibration and maintenance of Fixed Noise Monitoring Stations, Noise Monitoring of Mobile Noise Stations, Equipment Management, the Stationary Noise Measurement of running vehicles, Delineation of Noise Control Zone, and Non-Ionizing Radiation Monitoring, et cetera.
In the section of Manual Operation Air Monitoring Stations, this project had covered the following missions in Fengyuan, Wuchi and Wufeng. There are monthly sampling and analysis of dust fall, monthly one-point flow rate calibration, every half months TSP sampling analysis and maintenance, quarterly multiple-point flow rate calibration. All equipments in Manual Operation Air Monitoring Stations are in good working conditions. In contrast with year 2009, the mean concentration of TSP in year 2010 in Fengyuan reduced approximately 7.6μg/m3 compare to 2009, the mean concentration of TSP in year 2010 in Wuchi reduced approximately 6.8μg/m3 compare to 2009, the mean concentration of TSP in year 2010 in Wufeng increased approximately 2.4μg/m3 compare to 2009. The TSP geometric means of three Stations all meet the air quality standard in 2010. The concentration of TSP in winter was higher than insummer. There was a declining trend for a long time, in the TSP ingredient is high by the nitrate proportion. The dustfall in Taichung County in 2010 was equally 3.75 ton/square kilometer/month, the graduation was extremely slightly pollute.
In the section of Auto-Monitoring Stations, all measurement items were functioning well under weekly, monthly, quarterly, semi-annual and annual maintenance scheme. The data validity all achieved above 90%. In the project, we invited experts to perform functions verification and QA check, and we had improved instruments based on critical comments.
In 2010, the PSI (Pollutant Standards Index) of Taichung County revealing in Taiwan EPA report was 1.93%. As to the Maximum Index Pollutants, suspended particulates contributed the big part（52.4％）. The measurement data for the mid-Taiwan, the worst one was Taichung County standing for 1.92%, followed by Nantou County (1.78%), Taichung City（1.51％）, and then Changhua County (1.23%). Among Shan, Hai, and Tun, three districts of Taichung County, Tun had the worst air quality from its highest PSI and Hai had the better air quality from its lowest PSI.
In the section of Noise Monitoring, the regular calibration and maintenance of Fixed Noise Monitoring Stations were completed according to the contract. The calibration report and monitoring data were submitted monthly and the data validity was above 95%. In the section of the Noise Monitoring of Mobile Noise Stations, that took twice quarterly monitoring tests at each spot, and according to predetermined progress execution. In the section of Petition Case Noise Monitoring, we had completed 21 cases times. Most of petition cases spreading along heavy traffic roadsides. The monitoring results showed five cases not complied with noise regulation standard. In the section of Stationary Noise Measurement of running vehicles, including in coordination with the federal highway police to guard against the car racing mission and Vehicles noise sentiment cases, we had performed 35 times including 171 vehicles’ inspection. The disqualified rate was 35.1％ and the disqualified vehicles were mostly stock cars.
In the section of the Equipment Management, all the noise monitors had to be sent to the auditing teams in Shan, Hai and Tun districts for testing on 15th of every month. In the section of the Software Operation/Maintenance and Data Update, apart from submitting the self- evaluation forms and updating the database of the Noise Control Information System monthly, it provided Taichung County EPB with the assistance of calculating and uploading the self-evaluation results to EPA’s Noise Control Information System quarterly.
In the section of Non-Ionizing Radiation Monitoring, we had completed 7 cases according to the contract. The monitoring results showed all cases were lower than EPA’s recommended environmental values.
