6 Ambient air Status, Impact Assessment and Mitigation measures

6.1 Monitoring and Assessment of Ambient air Quality Status

6.1.1 Sampling locations

Arrangement of sampling locations shall conform to the following principles:

 According to the weather characteristics during sampling, sampling locations shall be set in the down wind direction of predominant wind direction;

 Objects sensitive to air pollution within a short distance;

 In consideration that the emission source of the project is mainly the traffic linear source, scope in a short distance along the roads is mainly affected by extension of air pollutant, therefore, sampling locations are mostly set near plannedly-chosen routes of the project.
As per aforesaid principles, 3 status sampling locations shall be respectively set within air assessment scope of Nanjiang Binlu and the Phase-II Project of the Third Ring Road . The three sampling locations are:

(1) Sampling locations at Nanjiang Binlu: 1# Yantai Mountain (Regular sampling location sampling location, present available materials can be used), 2# Fanchuanpu Catholic Church and 3# Jiangbian Primary School.


(2) Sampling locations at the 3rd Ring Road(Phase II) and Kuiqi Bridge: 1# Wushan Primary School, 2# Fujian College of Information and Technology, 3# South Emperor (Nan Di) Xanadu Administration (near Linpu Primary School) and 4# Kuiqi Primary School.
For the exact positions of all sampling locations, refer to Figure 5.1-1. For the sampling location of Kuiqi Primary School at the northern end of Kuiqi Bridge, see Figure 5.1-2

6.1.2 Items and Time for Monitoring

As per the categories of air pollutants discharged in the project, characteristics of ambient air pollution near the planned area of the project, and the relevant regulation ambient air, NO2, CO and PM10 can be chosen as monitoring items for the ambient air quality status.


According to related requirements in Technical Guidelines for Environmental Impact Assessment (HJ/T2.2-93) and Technical Code for Environment Impact Assessment of Highway (JTJ 005-96), the time and frequency for status monitoring of ambient air quality can be confirmed as the following: In the mid December of 2003, monitoring shall be carried on for 5 days and samples of CO and NO2 shall be taken for four times (one hour for each time) per day, the time is 7:00, 11:00, 14:00 and 19:00; samples of PM10 shall be taken once at each sampling site lasting for more than 24 hours.

6.1.3 Standards of Assessment

Ambient air Quality Standards (GB3095-1996) and the revised Class Ⅱ Standard is adopted, for more, refer to Table 6.1-1.

6.1.4.2 Assessment of Ambient air Status

(1) Hourly Average Values of CO: from Table 6.1-2, we know that the hourly average values of CO for 5 days (4 times per day) at 5 sampling locations are not up to Class Ⅰ of Ambient air Quality Standards (GB3095-1996) (i.e.≤10.00mg/m3).


(2) Hourly Average Values of NO2: from Table 6.1-3, we know that the hourly average concentration values of NO2 for 5 days (4 times per day) at 5 sampling locations are not up to ClassⅠof Ambient air Quality Standards (GB3095-1996) (i.e.≤0.12mg/m3), except that parts of frequencies and times of 2# Jiangbian Primary School on Feb.18, 2004 exceed ClassⅠ.
From Table 6.1-5, we know that the hourly average values of NO2 for 5 days at regular monitoring site of Yantai Mountain are not up to ClassⅠ.
Parts of frequencies and times of 2# Jiangbian Primary School on Feb.18, 2004 exceed ClassⅠ,but not up to ClassⅡ, through site inspection, it is mainly because there are many transmitting motor vehicles exhaust on the road outside the school during that period. No other obvious pollutant sources are found.
(3) Daily Average values of PM10: from Table 6.1-4, we know that the daily average values of PM10 for 5 days at 1# Fanchuanpu Catholic Church, 3# Wushan Primary School and 5# Cangshan South Emperor (Nan Di) Xanadu Administration are all not up to ClassⅡ(≤0.15mg/m3); the monitoring values of 2# Jiangbian Primary School on Feb.17, Feb.18 and Feb.19 are between ClassⅡ(≤0.15mg/m3)and ClassⅢ(≤0.25mg/m3), but not up to Class Ⅱon Feb.20 and Feb.21;the monitoring values of 4# Fujian College of Information and Technology on Feb.17 and Feb.19 are between ClassⅡand ClassⅢ, while not up to Class Ⅱon Feb.18, Feb.20 and Feb.21.
From Table 6.1-5, we know that the daily average values of PM10 for 5 days at regular monitoring site of Yantai Mountain are not up to ClassⅡ.
On account of no obvious pollutant sources nearby all the sampling locations, through site inspection, the reason why the PM10 of several monitoring sites exceeds ClassⅡ is possibly that dust in the air is increasing for continuous drought lasting several months, activities of people (especially the activities after school and come-and-go of students) and come-and-go of vehicles resulting in dust nuisance from the ground into the air.
