6.3.4.4 Assessment of Impact on Both Sides of Roads

(1) Concentration Distribution of CO on Both Sides of Road
The forecast results indicate that the concentration of pollutant CO in emission exhausted by motor vehicles on all the sections of the Project can meet the requirements of local environmental function in characteristics predicting years.
1) Nanjiang Binlu: The forecast results indicate that in predicted characteristic years, the concentration of CO on both sides of all sections is low, not exceeding the requirement of ambient air quality ClassⅡ.
2) The Phase-II Project of the Third Ring Road: Concentration of CO at 5 meters in low wind direction: under common weather condition, the long-term concentration of CO (in 2020) is only 0.492 and 0.514mg/m³ under the instability and neutral stability. Under bad weather condition, the maximum concentration of CO is 0.804mg/m³.
3) Kuiqi Bridge: The forecast results indicate that in predicted characteristic years, the concentration of CO on both sides of all sections is low, not exceeding the requirement of ambient air quality ClassⅡ.
(2) Concentration Distribution of NO₂on Both Sides of the Road
1) Nanjiang Binlu: As per forecast, under common weather condition, NO₂on both sides of roads will not exceed the standard in the characteristic years of 2010, 2015 and 2020.
Under bad weather condition, NO_Xin emission of motor vehicles will have a great effect on NO₂of both sides of roads. In the characteristic year of 2020, the concentration impact value of NO₂on both sides of section from Aofengzhou Bridge to Sanxianzhou Bridge will reach 0.27mg/m³ at 50m from outside of road.
After Nanjiang Binlu will have been built, pollution zone of NO₂with different width will come into being in the low wind direction along the road.
2) At 5m in the low wind direction of the Phase-II Project of the Third Ring Road: as per forecast, under common weather condition, except that the impact concentration of NO₂on the section from Fuxia Flyover to Kuiqi Bridge will exceed ClassⅡ in 2020, the impact concentration of NO₂on other sections will not exceed ClassⅡ of ambient air quality in all the predicted characteristic years.
Under bad weather condition, in the characteristic year of 2020, NO₂of the whole section, i.e., Wanbian Bridge-Fuxia Flyover and Fuxia Flyover-Kuiqi Bridge, will exceed ClassⅡ of ambient air quality at 5m outside of road, while in other characteristic years, the impact concentration of NO₂ on both sides of all sections will not.
3) Kuiqi Bridge: Under common weather condition, NO₂exhausted by motor vehicles will have an effect on ambient air of both sides of bridge, however, the impact value of NO₂at 10m outside of bridge will not exceed ClassⅡ of ambient air quality and the pollutants almost distribute within 50m of both sides of bridge.
Under bad weather condition, NO2 exhausted by motor vehicles will have a great effect on ambient air on both sides of bridge, for example, at 5m outside of bridge in 2020, the impact value of NO2 is 0.257mg/m3 when northerly breeze is stable, while the impact value of NO2 is 0.777mg/m3 when southeasterly breeze is stable.
