3.3.1 Ambient Air Quality Survey and Evaluation
3.3.1.1 Ambient Air Quality Monitoring
(1) Airport Monitoring Program
Set up three ambient air monitoring Sites at the airport area. See Figure 3-3-1 for monitoring sites.
(i) Monitoring Sites
1#Monitoring Site: Tashui Xiajia Village
2#Monitoring Site Fang Village
3#Monitoring Site: Peng Jiashan
(ii) Monitoring Factor and Analysis Methods
Monitoring Factor: TSP, PM10, SO2, NO2, CO, NmHc
Take samples according to the requirements of Ambient Air Quality Standards (GB3095-1996), and conduct monitoring analysis according to “Analysis Methods of Environmental Monitoring of Ambient Air and Exhaust Gas” issued by National Environmental Projection Administration.
(iii) Monitoring Period and Frequency
Monitoring Period starts from December 9, 2011 to December 15, 2011, keep monitoring for 7 successive days.
Monitor no less than 12 hours successively each time for the daily average concentration of PM10 and TSP; SO2 and NO2 monitoring include 1 hour concentration and daily average concentration, monitor 1 hour concentration 4 times per day at 02:00, 08:00, 14:00 and 20:00, and the sampling time shall be no less than 45min, successive sampling of daily average concentration shall be no less than 18 hours; monitor 1h concentration for NmHc, 4 times per day at 02:00, 08:00, 14:00 and 20:00.
Monitoring Frequency shall follow Ambient Air Quality Standards (GB3095-1996) and relevant national specifications and requirements.
3.3.1.2Ambient Air Quality Evaluation
(1) Evaluation Methods
Evaluate by way of single pollution index.
In the formula: Pi: single pollution index.
Ci: I Pollution Factor Monitoring Concentration (mg/m3);
C0i: I Pollution Factor Standard Concentration (mg/m3).
(2) Evaluation Standards
Evaluate according to Level 2 standard of Ambient Air Quality Standards (GB3095-1996); Evaluate NmHc by referring to 4.0mg/m3 of concentration limit of fugitive emission monitoring in Comprehensive Emission Standard of Atmospheric Pollutants (GB16297-1996).
(3) Monitoring and Evaluation Results
(i) Monitoring Results of Air Quality at the Airport
See table3-2-2 to table 3-2-6 for the monitoring statistics and evaluation results of the pollutants of each monitoring site.

It can be concluded from table 3-2-2-5 that the monitoring values of 1h concentration of all pollutants in each monitoring site do not exceed standards. The monitoring values of NmHc are lower than 4.0mg/m3, and thus are up to the standard.
According to table 3-2-6, the daily monitoring concentration of SO2, NO2, TSP and PM10 is up to the standard, the overall ambient air quality is good in this region.
The above monitoring results show that the ambient air quality is good in this region.

According to the ambient air monitoring statistics and the calculation results of standard index at the monitoring sites of the assessed Areas, the analysis and evaluation of the ambient air quality of the assessed Areas are as follows:
The daily average monitoring values of TSP, PM10, NO2 and SO2 in the assessed Areas are up to Level 2 standard of “Ambient Air Quality Standards” (GB3095-1996), and the pollution index of the daily monitoring values of all factors are lower than 1, and all these show that the ambient air quality of the assessed Areas are good.
