Current status of noise environment, impact assessment and mitigation measures

14.4.3 Impact of ambient air during operation period and mitigation measures

1) CO concentration distribution on both sides of the road: CO impact concentration on both sides of all the sections of Nanjiang Binlu, the Phase-II Project of the Third Ring Road and Kuiqi Bridge is relatively small both under general atmosphere conditions and unfavorable weather conditions in all the forecast characteristic years, which does not exceed level two of ambient air quality.

2) NO₂: Under general atmosphere conditions, except for the forecast characteristic year 2020, the concentration of NO₂ in all the sections of the Two Roads & One Bridge satisfies the level two requirement of environmental quality in the function areas; under unfavorable atmosphere conditions, NO_X in the emission of motor vehicles has a big impact on the ambient air quality on both sides of the road, and will be especially obvious in year 2020 due to the increment of traffic volume and pollutant, among which the environment qualify in Nanjiang Binlu can still keeps level two, and the concentration of NO₂ pollutant 50 meters around the Phase-II Project of the Third Ring Road and Kuiqi Bridge will be relatively high, exceeding the level two of environmental quality. However, the pollution is not severe in general.

3) Impact on sensitive places

1) Ensure the design running speed and relieve emission pollution.

2) Carry out mitigation measures regarding pollutant sources: The motor vehicles whose emission pollutant is discharged exceeding the standard level shall not pass through; strengthen the testing and repair of motor vehicles and support and cooperate with local governments to deal with motor vehicles’ emission pollution mitigation.

3) Mitigation measures regarding diffusion of air pollutant

Increase the diffusion distance of air pollutant. It is preferred to build warehouses, shopping malls and office buildings within 100 meters away the sides of the undeveloped roads so as to relieve the impact of residents caused by NO₂ which is discharged beyond the standard value; carry out greening on both sides of the road, thus to make full use of the plants to purify ambient air.

(3) Plans and measures on control of motor vehicle exhaust pollution in Fuzhou city

As motor vehicle belongs to mobile source, so it’s difficult to control pollutant from exhaust of motor vehicles through taking measures on single road & bridge or several roads & bridges, and it’s hard to do the deed like this. The domestic and overseas experiences show that it is an urban or regional system engineering to control the pollutant from exhaust of motor vehicles.

a. Group Indication System of Environmental Protection that is also called Yellow & Green Indication System is implemented on motor vehicle to conduct environmental protection grouping on motor vehicles. Green labeling is issued to gasoline vehicles compliant with Euro I standard and diesel vehicles above Euro II standard, while yellow labeling is issued to carburetor motor cars, open loop electrical ignition vehicles and those diesel vehicles failing to achieve Euro II standard.

After grouping, Fuzhou Traffic Management Bureau may clean up all the vehicles in the urban area. It’s required for vehicles with yellow labeling to accept inspection by the annual inspection station once half a year, while vehicles with green labeling are to be inspected once a year. Besides, it’s necessary to work towards the local code and regulation issued for limitation of running road section and running time for vehicles with yellow labeling.

In addition, screen the vehicles coming and going in an electronic supervisor way – electronic net. While license plate comes into electronic net, electronic net could identify the vehicle with yellow labeling or green labeling automatically and whether the vehicle is at unauthorized area. The number of vehicles screened would be exposed on media periodically.

b. At present, environmental supervisors have been arranged by Fuzhou Environmental Protection Bureau for strengthening the inspection, who would take photos or screen the vehicles with black smoke. The vehicles on road would be taken electronic evidences, and the supervision on vehicles with black smoke also would be strengthened. The executive persons of Environmental Protection Bureau take two half-days every week to take photos on road for those vehicles with black smoke, and these photos would be taken as the evidences for traffic policemen to deal with and punish. In another way, Traffic Police Station may be asked to transfer the documents of these vehicles to us so that we can deal with according to the relevant laws and regulations and expose the vehicles violating the rules on media.

c. As it’s not regulated in new “Law of the People’s Republic of China on Road Traffic Safety” that the traffic police department can punish the running vehicles with black smock, so it’s urgent to issue a local regulations to supplement the rules on punishment, including that it should be ruled that the running vehicles with black smoke can be punished and shall be ordered to the recheck point authorized by Environmental Protection Department, besides, the vehicles can’t pass the recheck twice shall be forced to discard.

d. The personnel at annual inspection station shall check on and supervise the vehicles on the check line, and issue the certification to those qualified vehicles.

e. Set more road check posts in urban area. Arrange one traffic policeman and two persons for environmental protection for every road check post to increase the check times and strengthen the executions of road check. Besides the fixed road check posts, running road check posts also shall be set to make surprise check of the running vehicles at the variable time and variable places.

f. Actively cooperate with media to periodically expose the vehicles violating rules, publicize the trends and promote the significance of work on motor vehicle, so as to improve people’s consciousness and strengthen the prestige and influence of our work.

g. Against the serious exhaust pollution caused by public buses and passenger vehicles, the emphasis of next work would be put on improve the phenomenon of black smoke from public buses and passenger vehicles. We could suggest the municipal government eliminate public minibuses so as to control the phenomenon of black smoke from the source.

a. Strength propagandizing

We have printed promotional publications on motor vehicle exhaust management to explain the common sense about motor vehicle exhaust and the management dynamic conditions. And such publications have been distributed to Fujian Vehicle Transportation General Company, Fuzhou Huawei Vehicle Transportation Company, Fuzhou Public Transportation Group Co., Ltd. etc. combining with the daily inspection to make promotions. At the same time, traffic companies would be urged to compile “50 Questions on Public Bus Exhaust” and distribute the books to the subordinated fleets.

b. Implement source control of new car exhaust pollution

Through forbidding to sell 2-cycle motorcycles in urban area, stopping issuing licenses for motorcycles and stopping selling and issuing licenses for carburetor cars with serious pollution and hard to govern, the pollution spread of motorcycles and carburetor cars is efficiently controlled. Strengthen the replacement and style choosing of taxis. Electric ignition technology and catalytic converter must be adopted for replaced taxis after July 4th, 2002, and the exhaust must be compliant with the national environmental protection standard so as to step by step control the exhaust pollution of taxis with high frequency of running in urban area on the source.

c. Expedite the replacement and updating

Urge the public transportation companies to replace vehicles seriously exceeding the limits of exhaust. Before the New Year’s Day of 2004, 215 minibuses were discarded, and 320 were updated. It is planned to update tens of vehicles before the end of the year.

d. Enforce the supervision and spot check of motor vehicle parking locations

Carry out constant supervision and spot check of public buses. In 2003 and the first half of 2004, 240 lines (time) of public transportation courses, altogether 1949 vehicles (time) were checked, and the qualification rate was 65%. 689 violating vehicles (time) were required to be fathered. At the same time, in 11 department in 11 departments with motor vehicle parking lots including Fuzhou passenger station, carry out spot check of exhaust of some long distance coaches, in this way eliminate pollution over the border by vehicles exceeding the limits.

e. Coordinate with the traffic police department to implement the annual inspection.

Fuzhou environmental protection department actively cooperate with the traffic police department to carry out annual inspection of motor vehicle exhaust in the annual inspection station of the traffic police. Only vehicles of which the exhaust is up to standards shall pass the inspection.

f. Carry out road inspection

For vehicles exceeding the exhaust limit, our bureau will urge the owners thereof to father within a time limit for re-inspection. The traffic police department will temporarily detain their licenses and issue Notification of Disposition and Field Record of Traffic Violation.

g. Promote the usage of clean energy of public buses. Coordinate with the public transportation companies in testing of biodiesel and exhaust purifier.
