This project was implemented from Feb. 9, 2011 to Dec. 31, 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, regular maintenance of Electronic Billboard, Noise Equipment Management, and Assessment of air quality and noise monitoring system, et cetera.
In the section of Manual Operation Air Monitoring Stations, 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 2010, the mean concentration of TSP and Dudtfall in year 2011 are higher than in year 2010. The TSP geometric means of three Stations all meet the air quality standard in 2011. The concentration of TSP in winter was higher than in summer. There was a declining trend for a long time, in the TSP ingredient is high by the nitrate proportion. The dustfall in Taichung City in 2011 was equally 3.04 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%.The PM10 analyzer intalled on February 9，and the HC analyzer installed on May 4 in Holi Station. In the project, we invited experts to perform functions verification and QA check, and we had improved instruments based on critical comments.
In 2011, the ratio with PSI (Pollutant Standards Index) over 100 of Taichung City revealing in Taiwan EPA report was 0.85%. As to the Maximum Index Pollutants, ozone contributed the big part. The monitoring data for the mid-Taiwan, the worst one was Nantou County standing for 1.8%, followed by Taichung City (0.85%), and then Changhua County (0.76%). Among Shan, Hai, and Tun, three districts of Taichung City, Tun district had the worst air quality from its highest ratio with PSI over 100（2.68％）and Shan had the best air quality.
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 90%. 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 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 EPB with the assistance of calculating and uploading the self-evaluation results to EPA’s Noise Control Information System quarterly.
