2 1. General Description
1.1 Project Background 1.1.1 Project Source The proposed G31 8Huaining section (1 ) Beneficial to the economic development in the poverty stricken areas; (2 ) Favorable to transportation centralization and decentralization of the main route (Hefei-Anqing Expressway ) ; (3) Fitted for the provincial 0I five-year plan of highway improvement, and priority given to the sections which have started construction but not completed yet in the 9gh five year plan so as to improve efficiency of the whole route and the road network; (4) The existing road sections cannot meet the increasing demand for transportation and need rehabilitation. (5) The average indicators (PQI) of road surface quality are low and surface is poor. G3 18 Huaining section is located in the south central areas of Anhui Province where the major transportation relies only on road for there is no railway to reach these areas. As the economy develops and the transportation increases, the existing road of narrow surface and poor quality cannot match the demands of economic development and transportation. Thus, Anhui Provincial Communications Department is applying for the World Bank loan (remaining savings) to support the rehabilitation of G318 Huaining highway section. The project is of great significance for improving the condition of transportation to the outside in the poverty stricken areas and stimulating local economic development and bettering the people's life. At the request of Anhui Provincial Communications Department of China, in July, 2001, Anhui Provincial Highway Administration Bureau entrusted the job of environmental assessment and preparation of the environmental impact assessment on G318 Huaining section of highway maintenance, to Hefei Design & Research Institute, Ministry of Coal Industry.
1.1.2 Status of Environmental Assessment The assessment unit, after accepting the entrustment, set up an environmental assessment group in July 2001. The group together with Anhui Provincial Highway Administration Bureau and Anhui Provincial Highway Survey and Design Institute carried out field visits and public participation and consultation along G318 Huaining highway section. The group conducted deep field investigation relating environmental status and environmental protective targets along the section. Based on the site visits, data collection and further study of the project feasibility study report, the group worked out the draft "Environmental Impact Report of G318 Huaining Section of Highway Maintenance Component of the World Bank financed Anhui Provincial Highway Project of China". The group got assistance from the environmental experts of the World Bank in the preparation of the report. Now the draft report is ready for the World Bank review. 1.2 Aim of the Environmental Assessment Qualitative or quantitative anticipation analysis and assessment are made on the possible environmental impact to be brought by the project construction. The work has been done on the base of the investigation into the natural and social environment and environmental quality within the assessment range of G3 18 Huaining section, and on the base of the combination with the understanding of the environmental status and relative environmental issues along the section. The report shall point out the potential problems and propose effective and reasonable alleviating measure correspondingly. The alleviating measure shall be put into practice to reduce the environmental impact during the project construction and operation to the lowest degree. The following targets shall be reached as well. ( I ) Possible environmental impact during the construction as well as the impact range and degree shall be fairly and objectively identified. (2 ) Investigation result shall be presented in the report based on the understanding of the public opinions via the investigation along the section. (3) Various measures of prevention, alleviation and reduction to the lowest degree of the negative impact shall be proposed, established on thc result of environmental impact anticipation and applicable compensation methods shall be proposed as well. The aim is to identify negative impact before the construction, raise attention in finalizing the design document and bid contract, and carry out the alleviation methods during the construction period. (4) The environmental assessment shall work as decision making reference, provided to the highway administration departments and local goverrnent institutions along the section in making environmental administration plan and environmental development programs. 1.3 Report Preparation Basis 1.3.1 The World Bank requirements (1) "Environmental Assessment" (OP4.01 ), the World Bank, January 1999 1.3.2 The national environmental protection laws, regulations and technical standard and guideline of assessment (2) "Environmental Protection Law of the People's Republic of China", Dated on December 26, 1989 (3) "Environmental Noise Prevention Law of the People's Republic of China" Dated on Oct. 29, 1996 (4) "Water Pollution Prevention Law of the People's Republic of China" Dated on May, 15, 1996 (5) "Air Pollution Prevention Law of the People's Republic of China" Dated on Aug. 29, 1995 (6) "Solid Waste Prevention Law of the People's Republic of China" Datedon Oct. 30,

3.1.3 Soil Vegetation Yellow and brown soil is the main soil of the local soil type and the paddy soil is the second. The whole area is classified as medium sub tropical zone in the south with the vegetation belt mixed of deciduous leave, broad-leaved evergreen and coniferous forest. There is little natural vegetation due to the long time of human activities. At present, most existing vegetation on both sides of the road and around houses are planted, namely white poplar, ailanthus, pagoda-tree, locust, platen, paulownia; Farming crops are wheat, paddy rice, bean, oil crop, peanut, cotton, vegetable, melon and fruits. 3.1.4 Soil Erosion Status According to the classification of soil erosion type of China, Huaining county belongs to southem red soil hilly area, having hydrodynamic erosion as the main feature. It is identified in the data provided by Huaining County Water Resource Department, local 2 soil erosion modulus is 1500 t/cm . a, ranking as slightly eroded grade. The soil loss 2 volume exceeds 500tIkm . a of soil unit loss allowance set by the state. 3.1.5 Surface Water Status
13 There are two major rivers in this area, Zhuliu river and Sanqiao river. Both rivers belong to Wan river system. The district is rich in surface water resources, about 483,000 m3 on average, per capita 1133 m3 and per mu of land 1375 m3 in the normal year. However water resource scatters unevenly, with much in the south while less in the north, much in the mountains while less in the hills, much in the summer while less in the winter. 3.2 Ecological Environment 3.2.1 Natural Ecological Environment The project is located in the slight hilly areas of Jianghuai Plain and Huaibei Plain where the history of human activities is very long and there is not any group of large-sized wild animals or natural vegetation. There is few rare wild animals or vegetation to be protected in this place. The man-planted vegetation and small wild animals could be seen within 200 m away from the highway, including forestation in the mounds, green belts on both sides of the highway, farming crops in the fields and various small wild animals as frogs, snakes and insects as well. The trees along the road are man-planted as poplar, platen, paulownia and willow and grow fine. Arbors are planted in the town and villages along the road and nearby, such as poplar, platen, paulownia, elm and metasequoia etc. According to the investigation along the highway and consultation with Huaining County Cultural Relics Administration Sector and Huaining County Forestation Bureau, there are not any natural protective zones, cultural relics, historic sites and wide animals and plants which need protection, within 200m away from the central line of the highway. 3.2.2 Agricultural Ecological Environment Most part of the project area is farming land. The main crops along the section are paddy rice, wheat, oil crop, corn, sweet potato and cotton and there is also forest in some areas. The crop output is usually high due to the suitable climate and rich soil and convenient irrigation. The people living nearby raise livestock and fowls, including pigs, cattle, sheep, chicken, ducks and geese etc. The raised aquatic products along the section are bighead, silver carp, crucian, carp and grass carp. Besides, there are some tea gardens, fruit trees of peach, pear, apple and so on. Local farmers plant various vegetables as greens, peppers, pumpkins and white gourds etc. 3.3 Social Economy The project covers the areas of Huaining County. The basic infornation of the project areas is shown in Table 3-2.

Huaiming 77.94 35740 0 69 2.786 3579 2238 Note: The data are extracted from Statistics in 2001 of Huaining County. According to "Anhui Provincial Statistics in the year 2000" (see Table 3-2), per capita GDP of Huaining County is lower compared with per capita GDP of Anhui Province and Anqing City, only accounting for 76% and 86% respectively. Less developed transportation is thought as one reason for the low GDP of the county. The project is believed to create more opportunities for local farmers to enter the market and participate in the competition so as to get rid of poverty.

The transportation relies on the highway in the county. Railway and waterway are less developed. It is known from the investigation that all the towns and villages have simple road connecting the state highway or provincial highway and have access to electricity and telephones as well. The local township govermnents and villages always lay emphasis on water conservation, so agricultural irrigation system is quite good and the towns and villages have certain capacity of flood control and drainage and resisting against drought. 3.4 Living Quality The investigation shows that over 99 % of proper aged children in this area are educated in the school. Local governments pay much attention to education. In addition to the schools set up by the governments, all kinds of training classed are held to update people's skill and capacity. Various social resources and channels are mobilized to promote people's cultural knowledge. There are 3 township clinics along the road, 3 middle schools and 6 primary schools A clinic is usually equipped with 10-20 wards and cures common diseases. Serious patients must be sent to city /county hospitals. The road improvement could better the healthy condition of rural residents and benefit the immediate save of serious patients
15 in this sense. 3.5 Natural Resources The district is located in the down stream of Changjiang river with main metal mines like copper, iron, gold, silver, lid, zinc, molybdenum and tungsten. There are also various energy resources such as soft coal, hard coal and uranium. Besides, there are many building materials like marble, tabular spar, lime, Baibei Stone and quartz stone.

4.1 Monitoring and Assessment of Environment Quality 4 1.1 Acoustic Environment For the purpose of obtaining the information of environment noise, the environment sensitive points were monitored from Jan. 22, 2002-Jan. 30, 2002 along the highway. The distribution of monitoring points is shown in Drawing 4-1. Table 4-1 shows monitoring record of environment noise Status. The environment noise of daytime is 48.0-56.2dB (A) and nighttime is 38.6-46.3dB (A) . The environment noise of daytime and nighttime of 7# Shijin Town Clinic exceeds the limit of Class I stipulated in "Environmental Noise Standard in Urban Areas" (GB3096-93) by 1.2dB(A) and 1,3dB(A), because the clinic is so near the highway. The clinic has taken some measures by equipping alufer windows. The noise metered in the patient ward declined to 47.2dB(A) in the daytime and 39.2dB(A) at night with window closed. Except for this clinic, all the other sensitive points meet the limit of Class 1 of "Environmental Noise Standard in Urban Areas" (GB3096-93), which means that traffic noise does not have much impact on the sensitive points along the highway.

17 4.1.2 Environment Air Xioushan Hospital and Sanqiao Hospital were selected as representatives along the highway to be monitored for the assessment of environment air. Xioushan Hospital is located in the village surrounded by farming land. The monitoring result could represent the environment air quality of the villages near the highway. Sanqiao Hospital is in Sanqiao Town along the highway. The monitoring result could represent the environment air quality of towns on the banks of the highway. The monitoring lasted for 3 days from Jan. 22, 2002-Jan. 24, 2002. Sampling was taken 4 times a day. The distribution of monitoring points is shown in Drawing 4-1. Table 4-2 shows monitoring record of environment air Status showing the value of TSP, NO2 and CO meet the limits of Class II set out in "Environment Air Quality Standard" (GB3095-1996).

4 1.3 Surface Water Monitoring was conducted on the surface water of three rivers relative with the project from Jan. 22 - Jan. 30 2002. Table 4-3 shows the monitoring record of the monitoring. The distribution of monitoring points is shown in Drawing 4-1. Table 4-3 shows the monitoring record. Since rivers are mainly used for irrigation of farming, the Class V (see Table 1-5) of water body classified in the "Surface Water Environment Quality Standard" (GHZBI-1999) is fit for the standard of the rivers, according to the water quality program of Huaining County Environmental Protection Bureau. The three rivers are proved below the limit of Class V classified in "Surface Water Environment Quality Standard".

0 12 4L 6 8 (km) 4.2 Investigation into Industrial Pollution Generators According to the investigation into industrial pollution generators, there are not any large sized constant industrial pollution generators along the highway, except for some small brickyards, township agricultural side products processing small-sized plants and social service sectors. Due to the poor surface of the highway, much instant TSP is produced when vehicle passes by. This affects air enviromnent of the highway to some degree but the impact is limited. Meanwhile, air whistle loud speakers are used frequently so that noise dB exceeds the limit instantly. In a word, the poor road and noise of vehicle shall cause some impact on the residents' life near the highway. 4.3 Special Environment Investigation According to the investigation along the highway and consultation with Huaining County Cultural Relics Administration Sector and Huaining County Forestry Bureau, there are not any natural protective zones, cultural relics, historic sites and wild animals and plants which need protection, within 200m away from the central line of the highway. Huaining County Cultural Relics Administration Sector and Huaining County Forestation Bureau presented the documents for evidence. See Annex 2 and Annex 3. However in case any buried ancient graves or historic ruins are discovered, the contractor shall have to report to local cultural relics and historical site administration departments. The contractor shall not go on constructing until relative departments complete concerned work.
20 5. Forecast and Evaluation of Potential Environmental impact
5.1 Construction Period The construction type of G318 Huaining section is classified as "rehabilitation", that is, to widen and reinforce the road surface and subgrade, with cement to pave the road surface. The existing road surface will be widened from 9.0m to 12.0 m on the base of the existing subgrade. G318 Huaining section covers a whole length of 31.830km. In the design document, the project does not involve in land acquisition and settlement. During 2 years' construction period, the negative impact of the construction on the nearby environment would cover the following aspects: 5.1.1 Impact on Acoustic Environment Quality 5.1.1.1 Impact of Mechanical Noise on Both sides of the Highway During the construction of G318 Huaining section, various machines and vehicles would be used. The main machinery contains shovel loaders, road rollers, paver buckets and dumpers that would make unavoidable noise during the construction. Dumpers are used to transport construction materials like cobblestones, sand and concrete, which would increase the traffic volume and affect to a larger scope. Table 5-1 shows the noise levels of various machines and vehicles. Estimate of Noise of Machines and Vehicles Table 5-1 No. Machinery Type Distancefromthenoise (m) L=,JdB (A) I

Most of the section passes through open fields and the rest passes through towns and villages. There are just a few houses on both sides, and most are used for commerce. Therefore, the direct noise impact on people is not serious. During the implementation of the project, the noise of construction and traffic would affect the quality of the residents' life on both sides of the road. G3 18 Huaining section covers a whole length of 31.830km, crossing the areas named Yeshan Town, Shiqiao Town, Shijing Town, Duxiu village, Huangdun Town, Sanqiao Town, Zhongliang village, Xiaoshi Town and etc. Many of the houses are for commercial use. The middle and primary schools and hospitals within 200m away from the road are presented in the following Table 5-2.

Attenuation type of point sound source would be applied considering the types of machines and their noise. Vehicles for transportation would be regarded as sound source in the construction. The following Table 5-3 is the estimate of noise level generated by main machines and vehicles to different distances during the construction.

22 "Noise Limits of Construction Site" (GB 12523-90) stipulates: noise of construction site is limited to 70-75dB (A) in the daytime and 55dB (A) at night. Table 5-3 shows that the distance within 40m in the daytime meets the regulated noise limit. At night, the distance beyond 200m can basically meet the noise limit. According to the investigation, 9 middle and primary schools and 3 clinics will be affected within the distance of 40m- 120m by the noise on both sides of the road of Huaining section. The construction noise might affect the sensitive points, but add little to the existing traffic noise. Thus, the construction noise in the daytime might generate slight impact on schools and hospitals. The strong noise of machines is forbidden at night in the places of adjacent hospitals. But night work will be done to reduce the daytime noise when the highway goes through a school without night students. 5.1.1.2 Impact of Mechanical Noise from the Mixing Station on the Environment The concrete mixing station will be set up at K22+600, the maintenance squad during the bridge construction. On the investigation of the site, there are no environmental sensitive points (such as schools, residential areas, sanatoriums or hotels) to be protected within 100m. Based on the analogy monitoring to the concrete mixing station by Hefei Environmental Monitoring Station, the actual tested noise values are shown in Table 54. The actual tested values show the noise values of the concrete mixing station are 55.4-57.6dB (A) in the daytime and 42.9-46.8dB (A) at night at the places 1.0m from the boundaries. So the noise values both in the daytime and at night exceed the "Noise Limits for Site Boundary of Industrial Enterprises" (GB 12348-90) Class I. I-lowever, by the estimate, the environment noise at 60m away from the concrete mixing station can meet the requirements of "Urban Areas Environment Noise Limits" Class I. Because there are no sensitive points within 100m of the site, it is believed in the evaluation that the noise will not affect the environment and people nearby.

23 5.1.2 Impact on Environment Air Quality 5.1.2.1 Impact of Road Dust on Air Environment During the construction period, the flying dust is mainly caused by the wind erosion on the bare road surface. The flying dust depends upon the travel speed of the vehicles passed by, the wind speed, the dust volume on the road and the dust humidity, among which the wind speed directly depend on the transmission distance. Table 5-5 shows the analogy monitoring to the flying dust in the similar condition that the necessary watering will reduce the flying duct 50%-80% during the construction. The impact on air environment will be distinctly decreased. And the TSP density at the distance 30m leeward can meet the "Environment Air Quality Limits " (GB3095-1996) Class I.
TSP of the Construction Road Table 5-5 Distance to the road (m) 0 20 30 100 200 TSP density No watering 3 64 0 95 0.38 0.28 0.18 (mg/m3 ) Watering 0.70 0.46 0.22 0.20 0.10
5.1.2.2 Impact of Tai Gas on Air Environment
As the transportation increases, the NO2 and CO in the tail gas by vehicles increase as well. According to he analogy monitoring conducted within the distance of 30m on both sides of the road, the average density per hour of NO2 and CO is 0.037-0.066 mg/m3 and 0.95> 1.65 mg/M3, which meet the limits of Class II set in "Environment Air Quality Limits" ( GB3095-1996). Therefore, it can be said that the NO2 and CO in the tail gas by the increasing vehicles will not pollute the air environment on both sides of the road. 5.1.2.3 Impact of Concrete Mixing Station on Air Environment It is planned to lay 381960 m2 of cement on road surface. The major pollutant is TSP when mixed, but the volume is very little. According to the analogy monitoring to the concrete mixing station by Hefei Environmental Monitoring Station, the average density per day of TSP is 0.11 mg/m3 and 0.08mg/M3 respectively at the distance 50m and 100m leeward of the mixing station, which is quite lower than the "Environment Air Quality Limits" (GB3095-1996) Class II. Therefore, as long as the mixing station is set up leeward away from the sensitive points, towns or villages, the major pollutant TSP will not affect anywhere. As there are no sensitive points within lOOm, it is considered in the evaluation that the mixing station will have no impact on air environment. 5.1.2.4 Impact of Construction Campsite on Air Environment
The main pollutants in the construction campsite are TSP and SO2 from the cooking
24 stoves. As the campsites use the house of the maintenance squad and it is in the wild field, and there are a small number of workers, the impact on the air environment is slight. 5.1.3 Impact on Ecological Environment The implementation of this project is to widen and reinforce shoulders of the existing road into road surface, there would be little impact on the enological environment. Some weeds on the shoulders and part of bush vegetation would be cut and destroyed. Around 4200 trees might be cut in the course of widening the road. There is not any grassland along the road. Since no land acquisition occurs, vegetation of farming field on both sides of the road would remain the same as before. The vegetation outside of the road shoulders would not be affected. In addition, some TSP pollutants would be generated due to the mixing of surface materials during the construction and would land on the vegetation and leaves of crops. Thanks to the rich rainfall in this area, the TSP landed on leaves would be rushed away with the rainwater and would not stay long, the impact on the growth of plants is negligible. 5.1.4 Impact on the Surface Water Environment During the construction period, the impact on the water environment involve in the following aspects: the residential wastewater and garbage in the construction campsite, the wastewater of washing machinery and the dropped machine oil in maintenance, and the watering when rolling the road. 5.1.4.1 Watering in the Construction During the works of rehabilitation of surface, water content would be kept for surface reinforcement in the rolling to reach the required degree of enforcement. Limited water would be used for the mixing of reinforcing materials and rolling. The water would be absorbed quickly by materials of surface and leave little water into the side ditches and farmland. Consequently there is no impact on water environment. 5.1.4.2 Residential Wastewater in the Construction Campsite There are 2 contract sections in this project, and each has set upl campsite, so there are 2 campsites. On the basis of the existing construction rules, each section has about 40 workers. The water used is limited, for there is no bathroom in the campsite and the toilet without water (dry toilet). In the investigation to the actual water consumption in the Hefei-Anqing Highway, the maximum water used is about 60 I/p/d, that is, the water consumption in each campsite comes up to 2.4m3/d and the wastewater is about 2.0m3/d. Therefore, the residential wastewater has a little impact on the surface water. As long as necessary measures are taken, the impact on water environment can be reduced to very little. 5.1.4.3 Wastewater in Washing Machinery and Dropped Machine oil in Maintenance When the machinery needs repairing and washing in a rainy day, the water used is just a little. Generally it can go directly into the ground, with little impact on the surface
25 water. There is no maintenance station in the construction, and all the repair work is done at the maintenance shops in the city or county. As result, no dropped machine oil in the construction site will affect the surface water. 5.1.4.4 Residential Garbage in the Construction Campsite The residential garbage of the workers is rather little. It volumes to about 20kg in each campsite in term of 0.5kg/p/d. It will be classified and treated in different ways. Therefore, the residential garbage will not affect the surface water environment with proper measures taken. 5.1.5 Impact on the Irrigation System As the project works on the rehabilitation of road surface, no river is involved. However, the road will pass through some of the irrigation system in the farmland. The irrigation canals, which come across the highway, will be increased in length, without changing the direction of water flow and flow volume. As long as attention will be paid not to block the ditches, canals or culvert with the construction materials so as to let the water through, the construction will have no affect on the water environment and the irrigation system. 5.1.6 Inpact on Soil and Water Conservation This project lies in hills. On base of the "Standards for Classes and Grades of Soil Erosion" (SL190-96) by the People's Republic of China, it belongs to southern hills with red soil. The allowable loss of soil and water is 50OVtkm 2 . a. Owing to the rehabilitation of the existing road surface, the affected area is small. According to the documents provided by Huaning Irrigation Bureau, the soil and water erosion modulus in this area 150Vt/km 2/a, the total volume of soil and water erosion will volume to 573t in this construction. So soil erosion caused by loss of soil and water in the construction is temporary and not serious. 5.1.7 Impact on Traffic in Bridge Construction 5.1.7.1 Impact on Traffic It has been considered in the design that temporary paths will be set up to let the vehicles and people pass through. So the bridge construction will have some affect on the traffic, but very little. 5.1.7.2 Impact on Construction Machinery on the Environment There are no schools and hospitals with 100m of the bridges to be built Therefore, the noise of bridge construction will have slight impact on the sensitive points. 5.1.7.3 Impact on the Loss of Soil and Water Because the base of the bridge will be dug down widely, the dug-out earthwork may cause loss of soil and water. However, the dug-open area is small and the loss of soil and water is relevantly small. The rivers crossed by the highway are all seasoning rivers, and they flow almost dry in winter. If the work is done in the dry season, the
26 loss will be reduced to lowest degree. Therefore, the loss of soil and water in bridge construction is slight. 5.1.7.4 Impact on Water Quality in the Rivers No wastewater will be discharged in bridge construction, so it will have no impact on the water quality. 5.1.8 Traffic Environment and Others In order to keep the traffic open during the construction, half of the road is under construction and the two halves in turn which might inevitably cause jam and affect traffic environment to some degree. However the negative effect is only temporary. There must be assigned person in charge of monitoring the traffic to ensure the project's quality and traffic order. In addition, certain affect would be generated by busy traffic of transportation on the construction site and would certainly bring inconvenience to the production activities, travel, living and rest of the residents along the road. But the impact is limited and could be acceptable. To sum up, the potential impact during the construction would be affect of traffic noise and TSP pollutants generated on air environment. As long as necessary measures are taken, the impact on the environment will be reduced to the lowest degree. In Chinese tradition, road repair has been considered as a kind of charities, so nobody would complain about it. 5.2 Operation Period 5.2.1 Impact from Traffic Noise When this project comes into operation, the traffic condition would be greatly improved after the completion of the project. The forecast of the traffic volume in G318 Huaining section in Table 2-3 shows that traffic volume would increase from the average 3309 no./d in the year of 2001 to 6393 no./day in 2010, and from the average 8649 no./d in the year of 2015 to 14083 no./day in 2025. The noise affect of traffic would rise as the traffic volume grows. The major affected residents are in: Yueshan Town, Shiqiao Town, Shiqing Town, Dunxiu Village, Huangdun Town, Sanqiao Town, Zhongliang Village, Xiaoshi Town. Most of houses on both sides of the road are for commercial purpose. As a result, the number of direct affected people by the traffic noise is restricted. When China Highway Project conducts EIA, Class I and IV of "Urban Area Environment Noise Limits" (GB3096-93) are used. The specific limits are shown in the Table 1-2. 4 primary schools, 4 middle schools and 3 hospitals are located within 200m on either bank of the road, and 30- 120 m away directly from the road. Estimate of environmental sensitive points of traffic noise from G318 Huaining Section is presented in the Table 5-6. Compared with the "Urban Areas Environment Noise Limits" Class I, the estimate shows there are some impact of traffic noise on Datang
27 Primary School, Shijing Primary School, Sanqiao Primary School, Sisong Primary School and Shijing Clinic. The impact on Shijing Clinic is the most serious, that would be 4.6dB (A) in the daytime and 7.8 dB (A) at night in 2005, and 5.3dB (A) in the daytime and 8.8 dB (A) at night in 2010.

5.2.2 Impact on Environment Air
During the operation of the project, the increasing emission of NO2 and CO would grow on environment air quality along the road corresponding to the rise of traffic flow by years. Nevertheless, the road is in the plain area with trees on both sides and good vegetation that is beneficial to air diffusion. Table 5-7 shows the forecast of the tail gas in G318 Huaining section based on the designed traffic volume. Compared with the "Environment Air Quality Limits" (GB3095-1996) Class II, the emission of pollutants NO 2 and CO beyond lOm on both sides of the highway can meet the standards. Therefore, the impact is slight on the environment along the road.

After the completion of G318 Huaining section, the traffic condition of the road would be improved greatly. The TSP produced by vehicles would decrease correspondingly compared with the existing road. The impact of TSP to the sensitive points would decline as well. In conclusion, the potential environmental impact of this project is from traffic noise and slight tail gas. 5.3 Other Environment Problems On the basis of the features of this "rehabilitation" project and the description of environment, the evaluation group thinks that the suggested project involves no intensive rehabilitation activities or sensitive areas, therefore, the impacts on the following environment problems are tiny or can be neglected: (1) There is slight affect on wild animals, for there are no species of wild animals. (2) There are no natural protection areas, scenic spots, cultural relics and historic sites along the road. (3) The "rehabilitation" project will not fetch or discard the earth, so there are no ecological problems. (4) This project involves no land acquisition or resettlement.

6.2 Possible Environmental Impact Compensation Measures 6.2.1 Design Period 6.2.1.1 Store Bulk Materials In design, the stacking site of the building materials carried from outside and the material mixing station should be kept as far as possible away from towns, residential areas, schools and hospitals and when designed. The easily dusting power materials must be covered. 6.2.1.2 Design the Culverts In the design, because the road surface is widened, the length of the culverts crossed with the highway must be relevantly added. The diameters or sections in part of the culverts are increased in order to guarantee the water flow. 6.2.1.3 Control the Road Dust In the construction procedure, watering equipment must be designed in order to water 31 the easily-dusting materials and decrease the dust. 6.2.1.4 Select the Site for the Concrete Mixing Station Yard mix is designed for the concrete of the road, and the site for the mixing station will be selected in accordance with the requirements of EIA. The maintenance squad is used for the station. There are no sensitive points within 100m. The mixer is equipped with dust-protected apparatus to reduce the flying powder. 6.2.1.5 Greening In the design of the rehabilitation project, the green belt outside the embankment on both sides of the highway, the slope protection works and side ditches must be taken into account. The varieties of vegetation should be properly selected in the design. All this must be designed with the main project.
6.2.1.6 Set Road Signs Road signs at crossed have been considered in the design, such as no whistling for towns, schools and hospitals, speed limit, pedestrian crosswalk, road bend and etc. 6.2.2 Construction Period The potential environmental irnpacts in the construction period involved in the traffic noise and road dust. The following mitigation measures are suggested: 6.2.2.1 Mixing Concrete Central yard mix of concrete must be used to decline the impact on air environment and acoustic environment. In the design, the site for the mixing station and the mixing equipment of environmental protection are selected. The construction must be in keeping with the design 6.2.2.2 Control the Construction Dust In the construction period, it is necessary to water the easily-dusting sections and materials in a fixed time, especially in the sections passing through villages and towns. In dry days, it is necessary to water 4 times a day in order to reduce the dust pollution to the nearby environment. 6.2.2.3 Store Bulk Materials and Prevent Dust Bulk materials must be stored 200m away from the sensitive sites of schools, hospitals, towns and villages. In dry days with strong wind, the easily-dusting bulk materials must be covered by canvas or plastic cloth to prevent the air pollution in the construction sections. 6.2.2.4 Treat Wastes Owing to all the building materials carried from outside, there are few wastes. If any, the action of central disposition in each section will be taken to conserve the water and soil.
32 6.2.2.5 Protect Crops The construction unit has the responsibility to tell the staff and workers to pay attention to protect the fields and crops along construction sections and not to destroy the farmland, so as to decrease the damage to the crops. 6.2.2.6 Ensure Traffic Order The half-side pavement will be used in the rehabilitation project, thus traffic block will not be avoided. In the construction sections, warning signs or detour signs must be put to ensure the project quality and keep the traffic in good order. There must be assigned person in charge of conducting the traffic. 6.2.2.7 Water and Soil Conservation When working with the fill or excavation, the exposed slopes must be done with vegetation. Some slopes and side ditches must be built up with bricks or stones, as designed, to stop the water and soil being washed away in the operation period. 6.2.2.8 Prevention Measures in Bridge Construction Temporary paths are considered in the design in order to reduce the impact on the traffic. It is suggested in the bridge construction that the surplus earth be used to strengthen the embankment of the river to reduce the block of river course and loss of water and soil. Moreover, it would be better to build the bridge in a dry season, if possible, to reduce the loss of water and soil. After the construction, the construction unit must clear up the reminders in case of blocking the river. 6.2.2.9 Cultural Relic Protection The on-the-spot investigation and the document provided by Huaining Cultural Relic Sector show that there are no cultural relics and historic sites within 200m along the highway. If any cultural relics are found in the earth, work must be laid aside and the spot must be protected while reporting to Huaining Cultural Relics Sector. Only after the cultural relics are unearthed, the work can go on by the approval of the cultural relic sector. Before the construction, the contractor must tell the workers that all the cultural relics and historical sites are state property. Everybody has the responsibility to protect it and hand in the cultual relics that are found to the local cultural relics sector. Anyone cannot snatch in an uproar and hide in private. 6.2.2.10 Road Signs By the end of the construction, the construction unit must set up the road signs in line with the design. Most of all, the sign of no whistling must be placed at the distance of 100m in the front of schools and hospitals within 200m on both sides of the highway to reduce the traffic noise. When the highway goes through villages and towns and there are schools and hospitals on the sides of the highway, signs of speed limit, village, crosswalk must be set according to the rules to avoid or reduce traffic accidents. 6.2.2.11 Greening
33 As the highway goes through the sensitive sections of villages, towns, schools and hospitals, attentions must be paid to the selection of tree varieties to lessen the pollution and beautify the environrment. The greening works must be finished together with the main project. About 4200 trees will be cut down when widening the highway, however, 25265 trees (6493 arbors and 18772 bushes) will be replanted after the rehabilitation. 6.2.2.12 Drainage of Road Surface The slopes of the subgrade and side ditches will be improved. The easily-washed slopes will be built with ditches and laid with bricks or planted with vegetation to protect soil erosion. 6.2.2.13 Environmental Sanitation and Disease Prevention in Campsites It is essential to pay attention to environmental sanitation and disease prevention. (1) toilets must be placed; (2) deposit tank must be set up to collect the residential wastewater; (3) daily garbage must be centralized to fill in spare places; (4) clean fuels will be used in cooking stoves to decrease the smokes; (5) propaganda column must be set up to prevent contagious disease and venereal diseases. During the construction period, the contractor is responsible for the worker's health check. If anyone is infected with contagious diseases or AIDS, the one must be sent to hospital at once or be separated for treatment. The contractor must tell the workers the knowledge of disease prevention and good health habits. Drug taking and whoring are banned to avoid contagious diseases or AIDS. If found, the one will be expelled and sent to the public security organs. 6.2.2.14 Set Accusation Signs for Environment Pollution The construction unit must set up accusation signs for environment pollution in the sensitive points, with the name of the construction unit, telephone number, the person in charge and the telephone number for the local EPB to solve the environmental problems in time if something occurs. 6.2.3 Operation Period 6.2.3.1 Measures to Prevent Traffic Noise Through the noise forecast in the operation period, the impact of traffic noise on the environment sensitive points outdoors would meet the requirements of "Urban Areas Environment Noise Limits" (GB3096-93) Class I. 6.2.3.2 Maintain Greening and Slopes In the operation period, close attention must be paid to keep 100% of the replanted trees alive. Meanwhile, side ditches and slope protection must be maintained to keep the ditches through. If the green belt or the slope have any damage, new trees will be replanted and the slope will be repaired in time. The green belt will be cultivated and pruned, and the harmful insects will be killed regularly. It is necessary to let the residents know the importance of road protection.
34 6.2.3.3 Maintain Road Signs Various kinds of road signs will be set up by the end of the construction. And the signs must be immediately changed or replaced if they are damaged or missed in the operation period. 6.2.3.4 Monitor the tail gas The highway management sector must cooperate with the local environmental monitoring station and check the tail gas from the vehicles at a regular time. The unqualified vehicles are banned to travel in the highway. 6.2.3.5 Manage Environment The highway squad is directly in charge of maintaining the road surface, the ditches and slopes as well. Meanwhile the squad is responsible to repair the damaged water conservation and greening. A management plan will be made out for the responsibility in each section so as to keep the highway and environmental protection in good order. 6.2.3.6 Monitor Environment In both construction and operation periods, the environmental monitoring plan in the EIA must be taken into great accounts, moreover, be implemented in accordance with the requirements. 6.2.4 Preventive Measures to Environmental Impacts 6.2.4.1 Table 6-2 shows the action plan for the environmental protection in G318 Huaining section. Table 6-3 shows the mitigation measures to the major environmental impacts.

The following is the summary of the public opinions: 1. 100% of the participants support the rehabilitation ofG318 Huaining section. They think first priority should be given to the construction of road in the process of becoming rich. To build road would benefit both the country and the people as well. 2. Participants think that construction of road could promote the traffic conditions, stimulate the economy, and improve the residents living quality. The respective percentage is 100%, 100% and 57.7%. 3. 38.5% and 13.5% participants think the impact of the road building is traffic noise and dust. 4. 34.6% and 61.5% participants think traffic jam and dust would be the focus people most concern in the construction period. Another 9.6% participants have not expressed any comments. The focus that people most care most during the operation period is traffic noise, vehicle tail air and sidewalks. The corresponding percentage of
47 participants is 76.9%, 9.6% and 5.8%. 5. 86.5% and 13.5% of the participants expressed their active attitude towards the protection of the road and greening of sides of the highway. 7.1.3 Public Opinion and Suggestions The investigation shows, although some participants think the construction and operation of the highway might produce negative effects such as traffic noise, dust and polluted air on the residents, this negative effect would be alleviate by way of planting trees on both sides of the highway after construction. In a word, the construction of the project would produce much more positive effect than negative effect. Most participants wish the project start the sooner the better so as to let the highway contribute earlier to society, environment and economy. In addition, it is suggested that highway administration departments should enforce the highway administration and maintenance and greening as well for the purpose of keeping the highway in good condition. To sum up, 100% participants expressed their positive attitude toward the project, which plays a good foundation for the project. Highway administration departrnents and construction units shall fully concem the public opinions and suggestions and try their efforts to bring the project into full play. 7.1.4 Public Participation and Inquiries Records Public participation and inquires records are shown in Table 7-3.

After the completion of draft EIA, Information 5 was provided to concerned social organizations. All the information were printed and issued to the concerned people or organizations that were inquired. * Information 1 - Construction Target The project name: G318 Huaining Section of Highway Maintenance Component of Anhui Provincial Highway Project of China. The project is the subproject of Hefei- Anqing Expressway. The first target is to improve transportation conditions of the poor areas of the provincial west. The second is to promote the surface quality and traffic capacity to assure the safety of drive. The third is to increase people's life level and encourage local economy via the rehabilitation. * Information 2- Project Description G3 18 Huaining section lies in the middle and south of Anhui Province, starting at the Yueshan Town in the east and ending at Chezhousi, covering the total length of 31.830 km. This section is the main access to Gaojie Expressway for most towns of Huaining County, and also a very important road leading to the tourist landscape of Tianzhu Mountain in Anqing City. The affected towns of the county are as follows Yueshan Town, Shijing Town, Duxiou Village, Huangdun Town, Sanqiao Town, Zhonglian Village and Xiaoshi Town. The sensitive points are identified as 9 schools and 3 hospitals, namely, Datang Primary School, Shijing Center Primary School, Tashui Primary School, Xiusban Primary School, Sanqiao Primary School, Zhonglian Primary School, Xiwang Middle School, Sisong Primary School, Xiaoshi Middle School, Shijing Town Clinic, Huaining No.4 Hospital and Sanqiao Hospital. G318 Huaining section traffic volume estimate(converted to medium sized vehicle): the year 2005, 4606 no./d; the year 2010, 6393 no./d; the year 2020, 11 226no./d; the year 2025, 14083 no./d. The total cost of the rehabilitation of G3 18 Huaining section is estimated RMB67,064,378 yuan. The project is planned to start in May 2002, and complete in April 2004, covering the period of 24 month. * Information 3- potential environmental impact of the project (1 ) The noise and dust during the construction shall have negative effects on the sensitive points along the highway. The construction shall bring inconvenience to the nearby residents in their daily life. The residential waste and wastewater of the construction sites shall affect environment. However the construction shall not affect the rivers and irrigation system of farming land. (2) The noise along the highway shall increase as the traffic volume increase once the highway is in full operation after completion of the project. The top noise value of daytime and nighttime in the year 2010, is estimated to reach 60.3dB (A) and 53.8dB (A) in Shijing Town Clinic. Now the Clinic has equipped alufer windows and doors. The noise of patient wards in daytime and nighttime is anticipated to be lower than the limit value when the windows and doors facing the highway are closed. As for
50 Datang Primary School that has no facilities of noise barriers, some action needs to be taken by building enclosing walls of 3m high and 30m long located at the place 5m away from classrooms. Then traffic noise shall not affect the sensitive point. After the improvement of the highway, traffic condition shall be better, dust shall be less and air environment along the highway shall be cleaner. * Information 4-Alleviation Plan of Environmental Impact (I) Designing stage: select proper place for storing building materials and for mixture, over lOOm away from sensitive points: carry out regular maintenance to noise machines; equip spraying vehicle to control dust; improve greening belts on both banks; enforce road drainage, slope protection and highway facilities like signs of warning indication and road direction etc. (2) construction stage: Building materials for road surface shall be centralized for mixture and delivered by vehicle to each construction site. Strong noise machines shall stop working at night in places where sensitive points are located. Spraying shall be done in the places with much dust whenever needed. The planting of green belts of highway shall be finished at the same time of the completion of major construction work. The temporary wastewater treatment facilities shall be established for the treatment of centralized residential wastewater and waste of construction site. ( 3 ) operation stage: Highway environmental management, environmental supervision institutes and environmental monitoring report system shall be reinforced. Highway environmental protection targets and environmental management plan shall be established as well. * Information 5-Conclusion of environmental impact assessment The monitoring results of major sensitive points along the highway shows noise of daytime and nighttime basically meet Class I set out in "Environment Noise Standard in Urban Area" (GB3096-93) , except for that of 7 # Shijing Town Hospital slightly exceed the limit. The monitoring of air environment shows TSP, NO2 and CO of sensitive points along the highway below the limits of Class II set out in "Environment Air Quality Standard". The noise of construction and dust in the implementation of the project shall produce certain effect on the sensitive points nearby, but the effect shall not last long and be limited. Environment pollution shall be controlled through various measures on the construction site and some action shall be taken to prevent from infectious disease, local disease and AIDS. Simultaneously propaganda and education shall be emphasized. Although traffic noise and polluted tail air generated during the operational period shall cause negative effect on the sensitive points along the highway, this impact shall be within the limit range. The impact shall be controlled once the alleviation measures are put into practice and green belts on both banks of the highway are built. Besides, much effort has to be made on the environmental management and maintenance. 7.2.2 Information Disclosure Channels

52 8. Conclusion
The proposed "rehabilitation" project of G3 18 Huaining section highway is one of the highway maintenance component of Anhui Province proposed to apply for the World Bank loan. The total length is 32km. This subproject is also one of the highway improvement projects in the 0th five-year plan. This is the action to promote transportation condition of poor areas in the west of Anhui Province and lay better foundation for local economic development and flow of goods and people. Huaining County per capita GDP accounts for 76% of the per capita GDP of the province. Less developed transportation constrains the growth of local economy. The improvement of the highway shall create more opportunities for local farmers to enter the market and participate in the competition. More agriculture products and side products shall appear in the market and more technical and scientific information shall spread in the towns and villages. The construction of the project shall bring typical social benefits and economic benefits. Investigation and public participation show 100% support the project, which means the project is so important to the local development. The civil works of the project shall implement within the range of existing reserved subgrade, thus there is no requirement for land acquisition or demolition or resettlement. According to the investigation and consultation with Huaining Cultural Relics Administration Sector and Huaining Forestation Bureau, there are not any objects requiring special protection along the highway such as natural protective zones, cultural relics, historic sites, tourist landscapes, wild animals and plants. The project implementation has sound social basis and natural environment. The monitoring results of major sensitive points along the highway shows noise of daytime and nighttime basically meet Class I set out in "Environment Noise Standard in Urban Area" (GB3096-93 ), except for 7# Shijing Hospital that exceeds the limit. The monitoring of air environment shows the daily concentration value of TSP and hourly concentration value of NO and CO are both below the limit of Class II set out in "Environment Air Quality Standard". The other ecological environment and social environment shall not produce constraining impact. During the implementation, noise and dust generated by the construction shall produce certain effect on the sensitive points along the highway, but the impact is temporary and limited to the acceptable level. The traffic noise and vehicle tail air caused by the increase of traffic volume shall not much affect sensitive points along the way. However during the operation period, environmental management, supervision system reporting procedure of monitoring should be strengthened so as to alleviate environmental impact to the lowest degree. To sum up, this project would produce certain negative effects on the resident's life, school's study and hospital's wards. However as long as the mitigation measures proposed in EIA are actually taken, the unfavorable effects will be effectively controlled and decreased to the lowest degree. Through the comprehensive
53 assessment, the social benefits and economical benefits are considerable. 100% of the people along the highway support the project. Therefore this project is feasible in conclusion.
